2018/03/20 | 390 | 1,592 | <issue_start>username_0: I am new in selenium and I have configured Cucumber with Maven and create one feature file but feature file's green icon is not displayed. Can I missed some configuration?
[Cucumber feature file](https://i.stack.imgur.com/198nk.png)<issue_comment>username_1: There is a plugin called **Natural 0.7.6** and it has a cucumber editor. If you download and install it from Eclipse Marketplace, then you will see the green icon for Cucumber feature file.
If you want to check the detailed steps, then please refer this article - [Add Cucumber feature file](http://www.automationtestinghub.com/add-cucumber-feature-file/)
Upvotes: 1 <issue_comment>username_2: That is because your version of IntelliJ is not recognizing the feature extension. For that, in IntelliJ, go to File --> Settings --> Editor --> File Types --> Mark "Cucumber Scenario" and add Registered Patters the \*.feature
The Cucumber green icon will be displayed the next tim you create a feature file.
Upvotes: 0 <issue_comment>username_3: after installing Natural plugin, open .feature file and right click on it.
then choice option as >> open with > others > from internal editor please select the cucumber editor > then above the ok button checked mark on "use it for all "\*.feature" files.
then you can see the all **.feature** file display green.

Upvotes: 0 <issue_comment>username_3: The problem is with this line:
```
if(sheet.cell(row+1,1).value == None):
```
`sheet.cell` is expecting to have a `str` cell name such as `A1` and not of type `int` for one parameter function.
You need to specify the `row` and `column` keys such as:
```
sheet.cell(row=row+1, column=1).value
```
if you specify an `int` type `row` and `column` variables
Upvotes: 2 [selected_answer]<issue_comment>username_4: I've created a small xlsx file myself with only one column filled with integers in the following order: 5, 4, 3, 2, 10 and 11. The code below seems to work for, for me at least:
```
column_index = 0 # 0 = A, 1 = B, ...
sheet_name = "Sheet1"
sheet = wb[sheet_name]
for r in sheet.rows:
value = r[column_index].value
print("value",value)
if value is None:
break
```
Output:
```
value 5
value 4
value 3
value 2
value 10
value 11
```
If I delete one intermediate value in that column, say 2, then the loop stops, like so:
```
value 5
value 4
value 3
value None
```
I hope this helps with your problem.

But its not working properly.<issue_comment>username_1: One option is to loop thru your `|`s and wrap it by 2. And using `.html()` update the table `tbody`
```js
$(function() {
var td = $(".test td");
var html = "";
for (var x = 0; x < td.length; x += 2) {
html += "|";
html += $(td[x]).prop('outerHTML');
html += $(td[x + 1]).prop('outerHTML');
html += "

}
$(".test tbody").html(html);
});
```

| |` after the second `|` ends. If you try the code like `$(".test tr td:eq(1)").after('|');`, it won't work. This will add the element like below.
[](https://i.stack.imgur.com/6FBA4.jpg)
Because using JQuery you can't add the closing as it as directly like above. You can get more article if you google it for why you can't add closing tag in JQuery. Now coming to our problem, how we can fix the issue.
Thanks to <NAME> giving the solution for the same kind of situation for `ul` and `li` elements [here](https://stackoverflow.com/a/9886743/3607064). In JQuery, you can use [nextAll()](http://api.jquery.com/nextAll/) with [andSelf()](http://api.jquery.com/andSelf/) to get the elements you want to move, then create a new `|
| |` and use [append()](http://api.jquery.com/append/) to relocate the elements. I refactor his solution to fix our issue like below.
```js
$("table.test tr td:nth-child(3)").each(function(){
$("|").insertAfter($(this).parent())
.append($(this).nextAll().andSelf());
});
```
```css
body {
font-family: Verdana, Arial, sans-serif;
font-size: 12px;
}
```
```html

```
when I access `Subscription.objects.all()` it's returning all the records in db without filtering. but, If I use below query
```
queryset = Subscription.objects.all()
queryset.filter(
models.Q(expiration_date__gte=datetime.date.today()) |
models.Q(
expiration_date__gte=datetime.date.today() - datetime.timedelta(days=40),
is_invoice_emailed=True
)
)
```
It is returning filtered results. Why?
I'm using django==1.11.11, python2.7 and db Postgresql
Please help. Thanks.<issue_comment>username_1: The method all() on a manager just delegates to get\_queryset(), and it is design to return all the objects on dB.
If you would use a filter method like filter() or exclude(), you would already have the QuerySet, and it return certain object which matches the condition of filter.
You can learn about queryset on
[django queryset documentation here](https://docs.djangoproject.com/en/2.0/topics/db/queries/)
Upvotes: 0 <issue_comment>username_2: Your `get_query_set()` method should be typed like `get_queryset()`
You may also use QuerySet directly instead of Manager:
```
class CustomQuerySet(models.QuerySet):
def get_result(self):
return self.filter(
models.Q(expiration_date__gte=datetime.date.today()) |
models.Q(
expiration_date__gte=datetime.date.today() - datetime.timedelta(days=40),
is_invoice_emailed=True
)
)
class Subscription(models.Model):
...
objects = CustomQuerySet().as_manager()
```
The pros of above is that you no longer have to provide Manager class.
From now you can use it like: `Subscription.objects.get_result()`

Every time, to start working using my project, I need to run each function manually one by one.

1. Create your own package and load it on the start-up, you will have all the function available. [A tutorial](https://cran.r-project.org/doc/contrib/Leisch-CreatingPackages.pdf)
2. Customize R start-up loading automatically your R files containing your functions. [A tutorial](https://www.r-bloggers.com/fun-with-rprofile-and-customizing-r-startup/) and [an example](https://stackoverflow.com/questions/36914701/run-r-script-with-the-start-up-of-r)

1. Bundle the functions and create a package -`yourpackage` and then load the package
```
library(yourpackage)

Upvotes: 1 <issue_comment>username_3: If you don't wish to take the package approach (which I agree is the best approach), you could stack all your functions on top of one another in an R script and source it on startup. One step instead of 6. End up with all the functions in your .GlobalEnv
Put this in an R script:
```
###Put in a script
eeee <- function(){
cat("yay I'm a function")
}
ffff <- function(){
cat("Aaaaaah a talking function")
}
```
If you use RStudio, the code would be as below. Otherwise change the source location. Do this in console (or in a script):
```
###Do this
source('~/.active-rstudio-document')
```
Then you can do:
```
eeee()
yay I'm a function
ffff()
Aaaaaah a talking function
```

for(f_path in file_path_vec){source(f_path)}

2018/03/20 | 777 | 3,628 | <issue_start>username_0: *Effective Java 3rd Edition, Item 18: Favor composition over inheritance* describes an issue with using inheritance to add behavior to a class:
>
> A related cause of fragility in subclasses is that their superclass can acquire new methods in subsequent releases. Suppose a program depends for its security on the fact that all elements inserted into some collection satisfy some predicate. This can be guaranteed by subclassing the collection and overriding each method capable of adding an element to ensure that the predicate is satisfied before adding the element. This works fine until a new method capable of inserting an element is added to the superclass in a subsequent release. Once this happens, it becomes possible to add an "illegal" element merely by invoking the new method, which is not overridden in the subclass.
>
>
>
The recommended solution:
>
> Instead of extending an existing class, give your new class a private field that references an instance of the existing class... Each instance method in the new class invokes the corresponding method on the contained instance of the existing class and returns the results. This is known as *forwarding*, and the methods in the new class are known as *forwarding methods*... adding new methods to the existing class will have no impact on the new class... It's tedious to write forwarding methods, but you have to write the reusable forwarding class for each interface only once, and forwarding classes may be provided for you. For example, Guava provides forwarding classes for all of the collection interfaces.
>
>
>
My question is, doesn't the risk remain that methods could also be added **to the forwarding class**, thereby breaking the invariants of the subclass? How could an external library like Guava ever incorporate newer methods in forwarding classes without risking the integrity of its clients?<issue_comment>username_1: >
> doesn't the risk remain that methods could also be added to the forwarding class, thereby breaking the invariants of the subclass?

Composition is an alternative to inheritance, so when you use composition, there is no sub-class. If you add new public methods to the forwarding class (which may access methods of the contained instance), that means you want these methods to be used.
Upvotes: 2 <issue_comment>username_2: Because you are the owner of the forwarding class, only you can add new methods to it, thus maintaining the invariant.
Upvotes: 0 <issue_comment>username_3: The tacit assumption seems to be that *you* are the one writing the forwarding class, therefore you are in control of whether anything gets added to it. That's the common way of using composition over inheritance, anyway.
The Guava example seems to refer to [the Forwarding Decorators](https://github.com/google/guava/wiki/CollectionHelpersExplained#forwarding-decorators), which are explicitly designed to be inherited from. But they are just helpers to make it simpler to create these forwarding classes without having to define every method in the interface; they explicitly *don't* shield you from any methods being added in the future that you might need to override as well:
>
> Remember, by default, all methods forward directly to the delegate, so overriding `ForwardingMap.put` will not change the behavior of `ForwardingMap.putAll`. Be careful to override every method whose behavior must be changed, and make sure that your decorated collection satisfies its contract.

>
So, if I understood all this correctly, Guava is not such a great example.

2018/03/20 | 3,610 | 9,077 | <issue_start>username_0: I have this code:
```
let result = Object.values(response.data.reduce((r,{ PO_NO, PO_LINE_NO, MATERIAL_NO, MATERIAL_NAME, PO_QTY, GRPO_QTY, GRPO_SHIPDATE }) => {
r[PO_NO] = r[PO_NO] || { PO_NO, LINES: [] }
r[PO_NO].LINES.push({
LINE_NO: PO_LINE_NO,
PO_QTY: PO_QTY,
MATERIAL_NO: MATERIAL_NO,
MATERIAL_NAME: MATERIAL_NAME,
GRPO_QTY: GRPO_QTY,
GRPO_SHIPDATE: GRPO_SHIPDATE
})
return r
},{}))
```
Which results into an array of nested objects. However, in the **LINES.push()** part, there are items that have the same line\_no, material\_no, material\_name, and po\_qty. The difference are grpo\_qty and grpo\_shipdate.
Is it possible to do remove the shipdate and get the sum of grpo\_qty with the same line\_no for every po\_no so that I only have a single row per line\_no of every po\_no?
Example of response.data content:
```
{
"PO_NO": 35159,
"LINES": [
{
"LINE_NO": 15,
"PO_QTY": 500000,

"GRPO_QTY": 320800,
"GRPO_SHIPDATE": "October, 07 2017 00:00:00"

"GRPO_QTY": 440000,
"GRPO_SHIPDATE": "October, 20 2017 00:00:00"
}
]
},
```<issue_comment>username_1: Well I think you can just iterate over each entry and call a reduce function on the lines array. In this function you can create a unique key with properties that stay the same and then sum up the grpo\_qty values.
It could look something like this
```
result.forEach(entry => {
entry.LINES = Object.values(entry.LINES.reduce((result, current) => {
const uniqueKey = `${current.LINE_NO}-${current.MATERIAL_NO}-${current.PO_QTY}-${current.MATERIAL_NAME}`;
if (!result[uniqueKey]) {
result[uniqueKey] = {
LINE_NO: current.LINE_NO,
PO_QTY: current.PO_QTY,
MATERIAL_NO: current.MATERIAL_NO,
MATERIAL_NAME: current.MATERIAL_NAME,
GRPO_QTY: 0,
};
}
result[uniqueKey].GRPO_QTY += current.GRPO_QTY;
return result;
}, {}));
});
```
Maybe you can provide a jsfiddle so it is easier to test.
You could also imagine to do this in your original reduce. Creating the unique key there and also sum up the values. Then you later just need to convert the object back to an array.
Theoretically it would also be possible to directly write everything in an array and find the existing entry with array.find(), but personally I'd suggest using one of the reduce. It is a lot cleaner, more performant and easier to read

If you have an array of POs, you can simply `map` our new function over it
```
console.log (poList.map (po => groupPoLines (po)))
// [ { PO_NO: 1, LINES: [ ... ] }, { PO_NO: 2, LINES: [ ... ] } ]

2018/03/20 | 548 | 2,191 | <issue_start>username_0: I'm building protractor tests for my Angular 5 app (built with Angular CLI). My problem is that to build a test takes a lot of time - each time I run `ng e2e` I need to wait until the app is compiled. That happens lot of times, since there are lot of mistakes with incorrect selectors in my code.
I have feeling that I'm doing something wrong. There must be a way to do protractor tests faster... am I right?<issue_comment>username_1: It's completely normal. E2E tests do not need to be run at every commit.
The best is to run them before a release or tagging.
Once in place, you'll only change them when your code evolves.
On my project, they take about 3 min to pass with 80 tests.
Upvotes: 0 <issue_comment>username_2: To skip the angular application compilation process, install protractor as global:
```
npm install -g protractor
webdriver-manager update
```
serve the application as normal **ng serve** and run protractor inside project folder, command line:
```
proctractor
```
Also you can modify file **package.json** in section 'scripts' adding line as:
```
"scripts": {
...
"protractor": "protractor"
},
```
then you can run your protractor tests in other command line prompt as:
```
npm run protractor
```
In addition: To run tests that matches specific name you can invoke:
```
protractor --grep "test name"
```
also if you want to be more strict with test names and suite names you can use `^` and `$` with `--grep` option, but you should know: suite name and test name is concatenated with space. So to run specific tests from different suites run command as:
```
protractor --grep "^Suite name1 test name1$|^Suite name2 other test name2$"
```
Upvotes: 2 <issue_comment>username_3: In a situation where you have a live environment, as in a running webapp, you can set up protractor to run against the live app. I'm in a situation where I never need to ng serve and run against the compiled app because we have multiple environments and I am not running tests against the production environment. In this situation is usually takes no time at all to develop and run tests.

2018/03/20 | 552 | 2,108 | <issue_start>username_0: When trying to run `grunt`, I get an error message:
```
Warning: Task "default" not found. Use --force to continue.
Aborted due to warnings.
```
I have already found several posts on this topic, and in each of them the problem was a missing comma. But in my case I have no idea what's wrong, I think I didn't miss any comma (btw, this content was copy/pasted from the internet).
```
module.exports = (grunt) => {
grunt.initConfig({
execute: {
target: {
src: ['server.js']
}
},
watch: {
scripts: {
files: ['server.js'],
tasks: ['execute'],
},
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-execute');
};
```
What could be the problem?<issue_comment>username_1: You didn't registered the default task. Add this after the last loadNpmTask
`grunt.registerTask('default', ['execute']);`
The second parameter is what you want to be executed from the config, you can put there more tasks.
Or you can run run existing task by providing the name as parameter in cli.
`grunt execute`
With you config you can use `execute` and `watch`. See <https://gruntjs.com/api/grunt.task> for more information.
Upvotes: 2 [selected_answer]<issue_comment>username_2: If you run *grunt* in your terminal it is going to search for a "default" task, so you have to register a task to be executed with Grunt defining it with the *grunt.registerTask* method, with a first parameter which is the name of your task, and a second parameter which is an array of subtasks that it will run.
In your case, the code could be something like that:
```
...
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-execute');
grunt.registerTask("default", ["execute", "watch"]);
...
```
In this way the "default" task will run rispectively the "execute" and the "watch" commands.
However [here](https://gruntjs.com/creating-tasks) you can find the documentation to create tasks with Grunt.
Hope it was helpful.

I made pairs of `userID` and `number_of_followee` with one MapReduce step.
With this data, however, I am not sure how to sort them in distributed systems.
I am not sure how `priority queue` can be used in either of Mappers and Reducers since they have the distributed data.
Can someone explain me how I can use data structures to sort the massive data?

If in China, git does not seem to work so I've to download the source as a zip file. What's the difference between the two?<issue_comment>username_1: "clone" uses git software on your computer to download the source code and it's entire version history.
"download zip" creates a zip file of just the current version of the source code for you to download - the project history is not included.
Upvotes: 1 <issue_comment>username_2: In China, `git` always works.
`github` was banned several years ago but now it works too.
There are two possibilities that `git` doesn't seem to work:
1) You are working behind some proxy.
In this case you need to configure your git or your system to enable your proxy.
Also, in some system, such as Ubuntu 16.04, `git` behind proxy may have some bug: <https://askubuntu.com/questions/186847/error-gnutls-handshake-failed-when-connecting-to-https-servers/187199#187199>
To solve this issue, you just need to remove the `git` and reinstall it from source.
2) `git clone` from `github` is too slow.
This is because there is a unstable network connection between China and `github`.
You can download a project using your browser. @username_1 has told you about the difference.

On Linux & Windows
* `git config --global http.proxy 'socks5://127.0.0.1:1080'`
* `git config --global https.proxy 'socks5://127.0.0.1:1080'`
On Mac

Note: this can not be tested in command line or playground. but it works on jenkins only.

```
dependencies {
testPlugins 'ru.yandex.qatools.allure:allure-jenkins-plugin:2.30.2'
}
```
Note: what can help is making sure Allure is available on your Jenkins, which you can check by going to <https://url-of-your-jenkins.org/plugin/job-dsl/api-viewer/index.html> and looking for "allure".
Hope this helps anyone who struggled with the error!

2018/03/20 | 1,722 | 5,427 | <issue_start>username_0: I just wanted to know if there is a way to improve this for loop, by skipping those if somehow.
Var `String` can have more parameters and their order can be casual.
In order to replace the param with a real value, I need :
1. To split it
2. To check what parameter is and in which position
Here is a synthetic example on how I thought it:
```
String = "{FullDate}_{Month}_{Day}_{Year}_{ElementID}_{ElementCD}"
String_split = String.split("_")
for params in range(len(String_split)):
if "FullDate" in String_split[params]:
# Do something
elif "Name" in String_split[params]:
# Do something
elif "ElementID" in String_split[params]:
# Do something
elif "ElementCD" in String_split[params]:
# Do something
elif "Year" in String_split[params]:
# Do something
elif "Day" in String_split[params]:
# Do something
elif "Month" in String_split[params]:
# Do something
```
UPDATE: That's what i would like to accomplish
```
# Default values
FullDate = now().format("yyyy-MM-dd_HH:mm:ss")
Name = "John"
ElementID = "Apple"
ElementCD = "01Appxz"
Year = now().format("yyyy")
Day = now().format("dd")
Month = now().format("MM")
############################
String = "{FullDate}_{Month}_{Day}_{Year}_{ElementID}_{ElementCD}"
String_split = String.split("_")
for params in range(len(String_split)):
if "FullDate" in String_split[params]:
Report_Name = Report_Name + FullDate + "_"
elif "Name" in String_split[params]:
Report_Name = Report_Name + Name + "_"
elif "ElementID" in String_split[params]:
Report_Name = Report_Name + ElementID + "_"
elif "ElementCD" in String_split[params]:
Report_Name = Report_Name + ElementCD + "_"
elif "Year" in String_split[params]:
Report_Name = Report_Name + Year + "_"
elif "Day" in String_split[params]:
Report_Name = Report_Name + Day + "_"
elif "Month" in String_split[params]:
Report_Name = Report_Name + Month + "_"
# Report_Name must return default values, ordered by String variable (eg: FullDate, 1st position; Month 2nd position etc..)
# >> "1999-01-01_10:10:29_01_01_1999_Apple_01Appxz"
# if the String variable changes the params order to
# String = "{Year}_{Month}_{ElementCD}_{FullDate}_{ElementID}_{Day}"
# Report_Name should return
# >> "1999_01_01Appxz_1999-01-01_10:10:29_Apple_01"
```<issue_comment>username_1: ---
**Before reading**:
- This is a solution that, as you mentionned, don't use dictionary
---
**Solution**
With:
```
#Default values
FullDate = '2010-01-01_00:00:00'
Name = "John"
ElementID = "Apple"
ElementCD = "01Appxz"
Year = '2010'
Day = '01'
Month = '01'
#--
String = "{FullDate}_{Month}_{Day}_{Year}_{ElementID}_{ElementCD}"
```
You can do this without `for` loop, just replacing as required:
```
Report_Name = '.RName_' + String
if "FullDate" in Report_Name:
Report_Name = Report_Name.replace('{FullDate}',FullDate)
if "Name" in Report_Name:
Report_Name = Report_Name.replace('{Name}',Name)
#...
if "ElementCD" in Report_Name:
Report_Name = Report_Name.replace('{ElementCD}',ElementCD)
print(Report_Name)

**[Be carefull] Another solution**
Or maybe you can use `.eval()` (see [documentation](https://docs.python.org/3/library/functions.html#eval)) to evaluate variable from its name. It requires that `parameters` and `variables` name are the same.
Here is a way to do this:
```
import re
Parameters = [re.sub('[{-}]+', '', s) for s in String.split('_')]
Report_Name = '.RName_' + String
for p in Parameters:
Report_Name = Report_Name.replace('{%s}'%p,eval(p))
print(Report_Name)
.RName_2010-01-01_00:00:00_01_01_2010_Apple_01Appxz
```
Be aware that you should use `.eval()` **carefully** - [see Why is using eval a bad practice](https://stackoverflow.com/a/1832957/3941704)
Check alternatives to this solution - [using `globals/locals/vars`](https://stackoverflow.com/a/7969953/3941704) for instance - if :
* You want a similar behaviour
* You think it is not safe enough for your problem
Upvotes: -1 [selected_answer]<issue_comment>username_2: * Use `for name in names` to remove all your `String_split[params]` noise.
* Remove the `{}` from your variables so you can use `==` rather than `in`.
* Use `+=`.
This gets:
```
names = "FullDate Month Day Year ElementID ElementCD".split()
for name in names:
if "FullDate" == name:
Report_Name += FullDate + "_"
elif "Name" == name:
Report_Name += Name + "_"
elif "ElementID" == name:
Report_Name += ElementID + "_"
elif "ElementCD" == name:
Report_Name += ElementCD + "_"
elif "Year" == name:
Report_Name += Year + "_"
elif "Day" == name:
Report_Name += Day + "_"
elif "Month" == name:
Report_Name += Month + "_"
```
You should also learn how to use format strings and the `**` operator. If you change your `FullDate` stuff to a dictionary then you can use:
```
REPORT_FORMAT = '{FullDate}_{Month}_{Day}_{Year}_{ElementID}_{ElementCD}'
report = {
'FullDate': now().format("yyyy-MM-dd_HH:mm:ss")
'Name': "John"
'ElementID': "Apple"
'ElementCD': "01Appxz"
'Year': now().format("yyyy")
'Day': now().format("dd")
'Month': now().format("MM")
}
report_name = REPORT_FORMAT.format(**report)

Upvotes: 0 <issue_comment>username_4: This is happening because you are trying to connect an outlet from the Interface Builder to a non-corresponding View Controller file, so that's why it only gives you the option to add an Exit action. Just make sure that you are in the same View Controller both in the IB and in the Assistant Editor.
P.S. I recommend you renaming properly every view controller so it will be easier to avoid this (make sure to change the name not only in the class but also in the IB). You can use the cmd + click when selecting the class name on the code and click on `Rename...` to change all at once. If you already changed it in your code, you have also to do it then manually in the IB, selecting the corresponding one from the drop-down menu of the Identity Inspector:

2018/03/20 | 1,085 | 3,614 | <issue_start>username_0: I am trying to kill a process by name which i will pass as a variable to a system command.
Below is what i have:
```
my $processName=$ARGV[0];
print "$processName\n";
system(q/kill -9 `ps -ef | grep '$processName' | grep -v grep | awk '{print $2}'`/);
```
The above script throws an error:
```
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
```
However, if i directly enter the process name inside the system command, it works.
Can someone help me on this?<issue_comment>username_1: You have the different variables `$processName` and `$jobName`, so the whole `` `` expression ends up empty. [`use strict`](http://p3rl.org/strict) would have pointed that out; it's useful even for three-line scripts. The `kill` error message is what you get when you run it without any arguments.
Pro tip: [`pkill`](https://gitlab.com/procps-ng/procps/#procps) exists, you can replace the whole problematic hack with one command.
Upvotes: 2 <issue_comment>username_2: One problem is that the command line that invokes the script has the name of the process which you then query, by design; so one thing found will be the script itself.
This can be guarded against, but why go out to the system with that big pipeline?
Query the process in Perl, for example with [Proc::ProcessTable](http://search.cpan.org/~durist/Proc-ProcessTable-0.39/ProcessTable.pm)
```
use warnings;
use strict;
use Proc::ProcessTable;
my $proc_name = shift // die "Usage: $0 process-name\n"; #/
my $pid;
my $pt = Proc::ProcessTable->new();
foreach my $proc (@{$pt->table}) {
next if $proc->cmndline =~ /$0.*$proc_name/; # not this script
if ($proc->cmndline =~ /\Q$proc_name/) {
$pid = $proc->pid;
last;
}
}
die "Not found process with '$proc_name' in its name\n" if not defined $pid;
kill 9, $pid; # must it be 9 (SIGKILL)?
my $gone_pid = waitpid $pid, 0; # then check that it's gone
```
Note that it is far nicer to "kill" a process by sending it `SIGTERM` (usually 15), not `SIGKILL`.
Looking for a process "name" can be perilous as there are many processes with long command lines running on a modern system that may contain that word. The code uses your requirement, to simply query by submitted name, but I recommend strengthening that with additional checks.
For many process details that the module can query see its [stub module](http://search.cpan.org/~durist/Proc-ProcessTable-0.39/Process/Process.pm).
Even if you'd rather parse the process table yourself I would get only `ps -ef` and then parse it in the script. That gives far more flexibility in ensuring that you really terminate what you want.

my $pid = `ps -ef | grep '$processName' | grep -v grep | awk '{print \$2}'`;

Upvotes: 1 <issue_comment>username_4: You can kill a process by name without invoking the shell by using [`IPC::System::Simple`](http://search.cpan.org/~pjf/IPC-System-Simple-1.25/lib/IPC/System/Simple.pm):
```
use IPC::System::Simple qw(systemx EXIT_ANY);
systemx(EXIT_ANY, 'pkill', '-9', '--', $processName);
```
Or you can collect a list of process IDs first:
```
use IPC::System::Simple qw(capturex EXIT_ANY);
kill 9, capturex(EXIT_ANY, 'pgrep', '--', $processName));
```
Then you don't have to worry about [`String::ShellQuote`](https://metacpan.org/pod/String::ShellQuote). See [this answer](https://stackoverflow.com/questions/3212128/perl-equivalent-of-phps-escapeshellarg) by username_1.

2018/03/20 | 1,171 | 3,871 | <issue_start>username_0: I'm trying STL in c++ now and found a question that I didn's understand.
I imagine a problem that needs to show each element and how many times that it occured in a vector. Since I knew how to use vector to finish this problem, I tried to use "set" or "map" to solve the problem.
```
vector v{ 'a', 'b', 'f', 'b', 'd', 'c', 'b', 'f', 's', 'v', 'x'};
map m; //
for (char n : v)
m.insert(pair(n, m[n]+1));
```
I thought that it will make counter plus each time when key was found, however, counter didn't work and each counter is 0.
After some change:
```
vector v{ 'a', 'b', 'f', 'b', 'd', 'c', 'b', 'f', 's', 'v', 'x'};
map m; //
for (char n : v)
m.insert(pair(n, m[n]++));
```
Then it work. I don't know why.<issue_comment>username_1: Have a close look at [insert](http://en.cppreference.com/w/cpp/container/map/insert) function: It only inserts an element, if it is not yet found!
The [index operator](http://en.cppreference.com/w/cpp/container/map/operator_at), in contrast, updates an element, if found, and creates a new one with default value otherwise.
So:
```
m.insert(pair(n, m[n]+1));
```
The first time you call this, `m[n]` creates already an element with default value 0. Then, you call `insert` on the map, but as the key is already found, no pair is inserted. So you get 0 all the time...
```
m.insert(pair(n, m[n]++));
```
Actually, from sight of `insert`, there is no difference: The entry in the map is created the first time you visit the map at position `n`, and you increment the entry directly. `insert` itself *never* actually inserts a pair...
So if you cut off the "do nothing" piece of code, all that remains is:
```
for (char n : v)
m[n]++;
```
For better understanding, a variant using `insert` equivalent to my code sample above:
```
for (char n : v)
(m.insert(std::pair(n, 0)).first->second)++;
```
Interesting, isn't it? Breaking it into pieces:
```
for (char n : v)
{
std::pair::iterator, bool> result = m.insert(std::pair(n, 0));
std::pair& entry = \*result.first;
entry.second++;
}
```
The core part of is this line:
```
std::pair::iterator, bool> result = m.insert(std::pair(n, 0));
```
The bool of the pair is set to true, if the element actually was inserted and to false otherwise. As not interested in this piece of information in the specific case, not used any further.
The iterator points to the element in the map - either the newly created one (bool part is true), or the one already found (bool part is false).
Upvotes: 2 [selected_answer]<issue_comment>username_2: First of all, your attempts to update map entries by calling `insert` are all ignored, because `insert` doesn't do anything if an entry already exists. To quote from the [C++ reference](http://en.cppreference.com/w/cpp/container/map/insert):
>
> Inserts element(s) into the container, if the container doesn't already contain an element with an equivalent key.
>
>
>
It gets a little clearer if you rewrite your code a little:
```
for (char n : v)
{
int& count = m[n];
int new_count = count + 1;
pair p(n, new\_count);
m.insert(p); // ignored because the key already exists
}
```
The second version, though, directly modifies the count that's inside the map, due to the `operator[]` returning a *reference* to the stored value, and the `operator++` directly manipulating the `int`. Your second version rewitten would look something like this:
```
for (char n : v)
{
int& count = m[n];
count++; // operates on the value that is stored in the map
pair p(n, count);
m.insert(p); // ignored because the key already exists
}
```
Even though your attempt to insert a new pair into the map is ignored again, since you directly modify the value that's stored in the map, the second version does what you wanted your code to do in the first place.

(Array access out of bound is undefined behavior) Here you have accessed array index out of bound.
First check if the access would be out of range - if that's the case you return from there, else you access it and check it. And then have the next recursive call.
```
if(k >= SIZE){
printf("target not found !!!");
}
else{
if(a[k] == target){
...
}
//next call
}
```
The `count` variable is not there when you return from the function. It is not needed or it's use not clear in this case.
The complete code can be as simple as this:
```
void verify(int a[],int target,int k)
{
if(k < SIZE)
{
if(a[k] == target)
printf("target found:%d at index= %d\n",a[k],k);
else
verify(a,target,k+1);
}
else
{
printf("target not found !!!");
}
}
```
Upvotes: 0 <issue_comment>username_2: ```
if(a[k]==target&&count
```
are always true as count is always zero in each iteration of recursion, you should use `k` for instead of `count` in your conditions
Upvotes: 0 <issue_comment>username_3: You are getting segmentation fault because `count` is a local variable of `verify()` function and in every recursive call to `verify()` function, the `count` initializes to `0` and the condition `count will always be `true`.
In every recursive call to `verify()`, you are passing `k+1` and comparing the element at `k`th location of array `a` with the `target` --> `if(a[k]==target&&count. At one stage the `k` will be having a value which is beyond the size of the array `a`. Your program is accessing the element beyond the array size which is undefined behavior which includes program may give segmentation fault.``
You dont need `count` variable at all. Just compare the value of `k` to with `SIZE` to ensure that it should not go beyond the array size.

RUN set -ex \
&& apk add --no-cache --virtual .plpython3-deps --repository http://nl.alpinelinux.org/alpine/edge/testing \

```
When I try to create the extension I get the following error:
```
postgres=# CREATE EXTENSION plpython3u;
ERROR: could not open extension control file "/usr/local/share/postgresql/extension/plpython3u.control": No such file or directory
```
But when I search for the files inside my container I can find them within a different directory:
```
/ # find / -name '*plpy*'
/usr/lib/postgresql/plpython3.so
/usr/share/postgresql/extension/plpython3u.control
/usr/share/postgresql/extension/plpython3u--1.0.sql
/usr/share/postgresql/extension/plpython3u--unpackaged--1.0.sql
```
How can I install `postgresql-plpython3` to a different directory or configure `postgres` to recognize my added extension?
**Update**
When I just `mv` the files to `/usr/local/share/postgresql/extension` I get the error:
```
postgres=# CREATE EXTENSION plpython3u;
ERROR: could not access file "$libdir/plpython3": No such file or directory
```
**Update 2**
So the issue with `$libdir` was that `pg_config --pkglibdir` points to `/usr/local/lib/postgresql` but `plpython3.so` is inside `/usr/lib/postgresql`. When I move everything to the according `/usr/local` directories I can successfully create the extension.
This leads to the question where I hope to find an answer. How can I install `postgresql-plpython3` to `/usr/local/...` instead of `/usr/...`?<issue_comment>username_1: I am fairly certain that if you use prebuilt packages you are stuck with hardcoded installation paths.
The easiest way around your problem is to create symlinks after installation:
```

```
Response res = given().
get(url).
then().
statusCode(200).
extract().
response();
JsonArray arr=new JsonParser().parse(res.jsonPath().get("al").toString()).getAsJsonArray();
```
You can then use JSONArray to find out the index and also the corresponding elements.
Upvotes: 1 <issue_comment>username_2: Regarding the assertions you can use the RestAssured built-in [GPath](http://james-willett.com/2017/05/rest-assured-gpath-json/) query syntax:
```
RestAssured.given()
.baseUri("http://your.server.com")
.accept(ContentType.JSON)
.get("/jsonFile")
.then()
.statusCode(200)
.body("al.findIndexOf { it.aid == 1461 }", is(2)) // findIndexOf returns zero-based list index
.body("al.find { it.aid == 1461 }._c", is("Gurgaon1"))
.body("al.find { it.aid == 1461 }.pc", is("122003"));

2018/03/20 | 592 | 2,806 | <issue_start>username_0: I'm looking for best practices for the following design: I have an abstract class and every concrete class extending that abstract class should be a singleton.
Background: The concrete classes are collectors that compile and log statistics about the operation of a complex legacy system. Collectors are accessible via a static registry, so there's no need to pass dependencies. The abstract class provides the interface to the registry.
I'm aware that there's no perfect solution that gives guarantees, properties have to be maintained by conventions. Nevertheless, there might be best practices for this case.<issue_comment>username_1: Technically you cannot prevent the concrete class to allow the creation of more than one instance of it.
But you have ways to try to conceptually enforce it :
* document clearly the interface
* set a constraint that require that these subclasses be beans managed by a dependency injection container
Upvotes: 1 <issue_comment>username_2: There is a solution to implement this, it is based on the following:
1. The constructors of the abstract class must have private visibility, so that it could be instantiated from inside only and to prevent it from being extended elsewhere.
2. The implementing singleton classes must be nested within the abstract class and must not be extendable.
3. The instances of the implementing nested classes are static members of the abstract class.
The drawback of this approach is that it can quickly become messy, due to nesting, especially if there are many implementations for singletons.
This might look as follows:
```
public abstract class AbstractEntity {
public static final AbstractEntity SINGLETON1 = new EntityImpl1(); // might be also instantiated lazily
/**
* Private accessor will not allow this class to be extended from outside.
*/
private AbstractEntity() {
}
static final class EntityImpl1 extends AbstractEntity {
private EntityImpl1() {
}
}
// other implementations...
}
```

* singleton property is managed by the registry. JavaDoc clearly states the correct and intended use
* a concrete instance is registered by a static `register(Instance.class, Instance::new)` method that has the class object and a supplier of instances of that class as arguments
* the registry maintains a map of String to instance objects, with the `toString()` result of the class object as key
Advantages
* instances can be private and can be placed close to the classes that using them (i.e., in the same package)
* instances are created once at first registry
Disadvantages
* instances are created by a constructor with empty parameter list
* the registry method needs two arguments

```<issue_comment>username_1: You could nest a if statement inside the timer that says if queue is full then disable this if statement then let the timer continue until its done without affecting the queue. I don't think it will cause conflict with your program because the timer is probably a closure.

2018/03/20 | 1,305 | 4,343 | <issue_start>username_0: I am learning Go and I am on channels now. I have written a simple program using channels. I have created two channels and the channels are passed to a function which is called concurrently.
My expectation is to print output form both the channels but in reality only one channel output is getting printed:
```
package main
import "fmt"
func square(dat int, ch chan<- int) {
ch <- dat * dat
}
func main() {
resp1 := make(chan int)
resp2 := make(chan int)
go square(20, resp1)
go square(10, resp2)
select {
case msg1 := <-resp1:
fmt.Println(msg1)
case msg2 := <-resp2:
fmt.Println(msg2)
}
}
```
Either the message from `resp1` is printed or that from `resp2` during each execution. Channels should block until something is pushed into it, right?<issue_comment>username_1: >

Select chooses one of a set. For example,
```
package main
import "fmt"
func square(dat int, ch chan<- int) {
ch <- dat * dat
}
func main() {
resp1 := make(chan int)
resp2 := make(chan int)
go square(20, resp1)
go square(10, resp2)
// Choose one
select {
case msg1 := <-resp1:
fmt.Println(msg1)
case msg2 := <-resp2:
fmt.Println(msg2)
}
// Choose the other
select {
case msg1 := <-resp1:
fmt.Println(msg1)
case msg2 := <-resp2:
fmt.Println(msg2)
}
}
```

>
> A "select" statement chooses which of a set of possible send or receive operations will proceed.

>
> If one or more of the communications can proceed, a single one that can proceed is chosen via a uniform pseudo-random selection.

If you want to read from both channels, rather than having `select` figure out which one is ready to be read from (or select one pseudo-randomly if both can be read from), don't use `select`. Just read from both:
```
msg1 := <-resp1:
fmt.Println(msg1)
msg2 := <-resp2:
fmt.Println(msg2)
```
**Update**
If, as @username_1 suggests, your goal is to read from both channels, starting with whichever is ready first, I'd think something like this would be a reasonable approach:
```
func main() {
resp1 := make(chan int)
resp2 := make(chan int)
readsWanted := 0
readsWanted += 1
go square(20, resp1)
readsWanted += 1
go square(10, resp2)
for i := 0; i < readsWanted; i++ {
select {
case msg1 := <-resp1:
fmt.Println(msg1)
case msg2 := <-resp2:
fmt.Println(msg2)
}
}
}
```
You could of course hard-code the loop to only run twice, but I have an aversion to such things, although in this simple example it doesn't much matter.
Upvotes: 2 <issue_comment>username_3: As per your code in the select whenever any case matches will execute and main function will terminate .That is why it is only printing the single channel value.
You can fix this by doing something like this :
```
package main
import (
"fmt"
"os"
"time"
)
func square(dat int, ch chan<- int) {
ch <- dat * dat
}
func main() {
resp1 := make(chan int)
resp2 := make(chan int)
go square(20, resp1)
go square(10, resp2)
time.Sleep(1 * time.Second)
for {
select {
case msg1 := <-resp1:
fmt.Println(msg1)
case msg2 := <-resp2:
fmt.Println(msg2)
default:
close(resp1)
close(resp2)
fmt.Println("no value recieved")
os.Exit(0)
}
}
}
```
Output
```
100
400
no value recieved
```

2018/03/20 | 923 | 3,501 | <issue_start>username_0: In my project I have a Polymorphic relation. This relation is as followes:
```
Plugins
id - integer
composer_package - string
Themes
id - integer
composer_package - string
Products
id - integer
name - text
...
commentable_id - integer
commentable_type - string
```
When I need to display all the products that are a Theme I do the following:
`$themes = DB::table('products')->orderBy('id', 'asc')->where('productable_type', Theme::class)->get();`
The code above provides me with a list of all the products where the `productable_type` field is filled with `App/Theme`, I display them with a foreach loop like this `@foreach($themes as $theme)`. Now my problem is.
I need to get the `composer_package` from the themes table that belongs to that product. So say for instance. I get a product from the products table where the `productable_id` is 3. I want the value of the `composer_package` field in the themes table where the ID is 3. When I do `{{ $theme->products->composer_package }}` or `{{ $theme->composer_package }}` It gives me the error `Undefined property` What is causing this?
This is my product model
```
public function product()
{
return $this->morphTo();
}
public function order_items()
{
return $this->hasMany(Orderitems::class);
}
```
And this is my theme model
```
public function webshops()
{
return $this->hasMany(Webshop::class);
}
public function products()
{
return $this->morphMany(Product::class, 'productable');
}
```
Thanks in advance!<issue_comment>username_1: Your table has "commentable", but your model is looking for "productable". You're also missing a method.
in your **product** model add:
```
public function commentable(){
return $this->morphTo();
}
```
in your **theme** model modify the products() method to:
```
public function products(){
return $this->morphMany(Product::class, 'commentable');
}
```
You could also update your `commentable_type` and `commentable_id` columns in your table to `productable_type` and `productable_id`, in which case you need to rename `commentable()` in the code for the product model above to `productable()`, and `'commentable'` to `'productable'` in the code for the theme model above.

Upvotes: 0 <issue_comment>username_2: Is there any reason you are using the `DB` facade to pull data instead of the actual models?
One issue your are having is that your polymorphic relationship is stored in the commentable\_id / commentable\_type field, while your function name is product. Laravel does some of its magic just by naming alone, so let's make sure the column names and polymorphic function names match up in the product model:
```
public function commentable()
{
return $this->morphTo();
}
```
After that, try something like this in the controller:
```
$themeProducts = Product::where('commentable_type', Theme::class)->get();
```
And this in the view
```
@foreach ($themeProducts as $themeProduct)
{{ $themeProduct->commentable->composer_package }}
@endforeach
```
Upvotes: 2 [selected_answer]<issue_comment>username_3: Create relations with the model as mentioned in above answers, then you can retrieve relations using with helper.
E.g.:
Product::where('commentable\_type', Theme::class)->with('commentable')->get();
and then can directly use as mentioned above.
e.g.: $themeProduct->commentable

What am i doing wrong?<issue_comment>username_1: The error message simply states that you are feeding the wrong dimensions to the placeholder y while running the optimization algorithm and cost function (through feed\_dict). Check whether the dimensions are correct.
Upvotes: 2 <issue_comment>username_2: Without the data to run the code myself I have to guess. But the `ValueError` indicates that the dimension of your input from `x_batch` (100, 150, 70) does not match the shape of the placeholder (None, 150).
If I understand your code correctly, each image you are trying to classify has 150x70 pixels. If that's true then I would flatten each of those into a vector and use that vector's length as the placeholder `x`'s dimension (None, 150x70).
Also, it seems, `y` doesn't have a specified shape. In this case it should be (None, 2). If there is no particular reason why you encode your two labels "fake" and "authentic" as two dimensional vectors, you could also use a just one dimensional vector.

2018/03/20 | 905 | 3,406 | <issue_start>username_0: I am a bit confused about new rules about copy elision and actually I am not even sure if it applies in this case. I have this:
```
template struct foo {
T t;
foo(const T& t) : t(t) {}
~foo() { std::cout << "destructor \n"; }
}
template foo make\_foo(const T& t) { return {t}; }
```
where `make_foo` is only to allow deducing the parameter (in the real code `t` is a lambda, but I left it out here for the sake of simplicity, or rather for the sake of confusion, sorry for that) as in
```
auto x = make_foo(123);
```
Now I need to be absolutely sure that `foo`s destructor is called exactly once: when `x` goes out of scope. I am afraid this is a unclear-what-you-are-asking question, but if it is that obvious that there wont be any temporary `foo`, that would be answer enough ;).
**In C++11, can I be certain that there wont be a temporary `foo` in `make_foo` that will be destroyed? The destructor should be called only when `x` goes out of scope.**
As correctly pointed out in a comment, this question is the Y part of a XY question and the X part is that I want to implement some end of scope functionality. The destructor of `foo` has some side effects (in the example the `cout`) that should be called at the end of scope of `x` but not in `make_foo` in case there would be some temporary `foo`.<issue_comment>username_1: Since C++17 there is guaranteed to be no temporary.
In C++14 and earlier, there must be an accessible copy/move constructor, and it is optional to the compiler whether or not there is actually a temporary.
As far as I'm aware, the only compiler that would actually manifest a temporary is older versions of MSVC in Debug mode.
Upvotes: 1 <issue_comment>username_2: In C++11 copy elision even for nameless temporary only allowed not mandated. It's described here [copy elision](http://en.cppreference.com/w/cpp/language/copy_elision). It is mandated since C++17.
Also in C++17 you will have automatic deduction guides, so you will not need such a construction.
And you can test your compiler, because most of modern compilers will elide copying here.
Upvotes: 3 [selected_answer]<issue_comment>username_3: In your case to be sure that destructor will not be called for unnamed object you can bind return value to **const reference**.
To clarify what happens if we not rely on copy elision:
```
template foo make\_foo(const T& t) { return {t}; }
```
In this function, return object will not be constructed in scope of that function. It will create **temporary unnamed object** out of the scope.
If you will bind return value to a **new named object** move constructor will be called(or copy if move is not defined) to create you **new object** from **returned temporary**. However if you bind returned temporary to **const reference** it will be strictly bound to that reference and no new objects will be constructed and temporary will not be destructed till that reference is out of the scope.
EDIT:
To not mislead you. Constructor for temporary called in function scope, but lifetime of that temporary will indeed be prolonged to lifetime of const reference
If you need more info you can check this answer. It refers to the C++ standard.

2018/03/20 | 251 | 1,058 | <issue_start>username_0: I want to save different revisions of a file from MKS Integrity using the Command Line Interface. The aim is to save these two files locally and use a script I wrote to compare them.
When I check the member history I can double click on the Revision Number and the file opens up in the chosen Editor. This file is saved in the TEMP Folder locally.
How can I do it using the command line arguments. Till now I have found the ***si edit*** command. This opens the file locally and creates a copy in the TEMP Folder but with a weird name.
If someone could help me with a better command that is available and I have overlooked in the documentation or if someone could tell me how the name is created?<issue_comment>username_1: Try using the `projectco` command.
```
si projectco --nolock --project= --targetFile=
```

2018/03/20 | 967 | 3,361 | <issue_start>username_0: I have an array of people with certain information about them.
I want to filter this array according to religion, gender, and record number at the same time.
Is there a way to do?
Here is **PEOPLE** Array:
```
{
"Id": 1270,
"FirstName": "name",
"LastName": "<NAME>",
"Religion": "religion",
"RecordNumber": 1,
"Gender": "male",
"Contacted": false,
"NeedsTransportation": false,
"WhenContacted": null,
"ContactedByWho": null,
},
{
"Id": 1383,
"FirstName": "name",
"LastName": "<NAME>",
"Religion": "religion",
"RecordNumber": 1,
"Gender": "male",
"Contacted": false,
"NeedsTransportation": false,
"WhenContacted": null,
"ContactedByWho": null
},
{
"Id": 1394,
"FirstName": "name",
"LastName": "<NAME>",
"Religion": "religion",
"RecordNumber": 1,
"Gender": "male",
"Contacted": false,
"NeedsTransportation": false,
"WhenContacted": null,
"ContactedByWho": null,
}
```
Thanks for any help.<issue_comment>username_1: Use `filter`:
```
const people: Person[] = [...];
people.filter(p => {
return p.Religion === (...) // condition for religion
&& p.Gender === (...) // condition for gender
&& p.RecordNumber === (...); // condition for record number
});
```
Of course the conditions needn't be equality comparisons, and neither you've got to use AND operators. The idea is that the `filter` method will return a new array containing only those items for which the function passed as an argument returns `true`. Inside you can make any checks you need.
Upvotes: 3 [selected_answer]<issue_comment>username_2: Why cant you just do `filter`.
```
var filteredResult = x.filter((x)=> (x.Id == 1394) && (x.Religion =="religion") && (x.Gender=="male") )
```
Of course, you can use any operator which can give you a boolean true for the item you are iterating to get that item in the result array

}]
const FILTER = (RELIGION, GENDER, RECORD_NUMBER) => {
return people.filter(({Religion, Gender, RecordNumber}) => Religion === RELIGION && Gender === GENDER && +RecordNumber === +RECORD_NUMBER)
}
let filteredPeople = FILTER('christian', 'male', 1)
console.log(filteredPeople)
```
I prepend the `+` operator before the `RecordNumber && RECORD_NUMBER` arguments incase it is passed as a String e.g `+'1' === 1`

2018/03/20 | 6,529 | 17,245 | <issue_start>username_0: I have a problem with integrating Google Play Services into my Unity game. I am sure the setup is correctly done on the google play developer console/google play API, and even Unity.
Using ADB Logcat, here is my error log text : <https://hastebin.com/varilupaxi.scala> (on short, the errors are "Could not register one or more required Java classes." and "InvalidOperationException: There was an error creating a GameServices object.").
Any idea how to fix this ? I also have the latest version of the Google Play Services(0.9.50).
Here it's my Unity C# code : <https://hastebin.com/iqajeguvop.cs>

2018/03/20 | 622 | 2,520 | <issue_start>username_0: I am using google maps and drawing polylines on it by passing array of coordinates on each location update. After plotting the polyline i first remove the previous one and then i am plotting new polyline based on updated coordinates array list. Problem is, google maps is plotting a separate polyline from starting to end point on each location update.
I know mistake is somewhere in the hierarachy of calling things. Can anybody help me figuring this out.
This is the method in which i am updating the camera focus and plotting polylines.
```
private void moveCamera(Location location) {
if (location != null) {
if (polyline != null) {
polyline.remove();
}
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(location.getLatitude(), location.getLongitude()), 16));
coordList.add(new LatLng(location.getLatitude(), location.getLongitude()));
// Create polyline options with existing LatLng ArrayList
polylineOptions.addAll(coordList);
polylineOptions
.width(5)
.color(Color.RED);
// Adding multiple points in map using polyline and arraylist
polyline = mMap.addPolyline(polylineOptions);
}

I can not figure out the problem. It would be great if anyone help me about this issue. Thank you.<issue_comment>username_1: The problem is in the following line
```
data = json.load(reader(res))
```
when your response is not a json string, `JSONDecodeError` occurs. so, add an additional logic to see if the response is `None` or a `json` string. First thing, print the `reader(res)` and see what the return is
Upvotes: 2 <issue_comment>username_2: I finally figured out the problem! Using the `requests` library have solved my problem now I can filter the api request.
```
data = requests.get('https://api.xxxxx.com.tr/v1/articles', headers =
headers, params={"$filter":"Path eq '/xxxxxx/'"}).json()
```
I am leaving this answer here for anyone else who can need this solution in the future.

```
mysqldump -u xxxx -p dbxxx > xxxx270613.sql
```
what is command to take mysqldump with UTF8 ?<issue_comment>username_1: Hi please try the following.
```none
mysqldump -u [username] –p[password] --default-character-set=utf8 -N --routines --skip-triggers --databases [database_name] > [dump_file.sql]
```
Upvotes: 6 [selected_answer]<issue_comment>username_2: `--default-character-set=utf8` is the option you are looking for the one can be used together with these others:
```
mysqldump --events \
--routines \
--triggers \
--add-drop-database \
--compress \
--hex-blob \
--opt \
--skip-comments \
--single-transaction \
--skip-set-charset \
--default-character-set=utf8 \
--databases dbname > my.dump
```
Also, check the `--hex-blob` it helps to dump binary strings in hexadecimal format, so I can guaranty (be more portable) making the import to work.
>
> The `--databases` option causes all names on the command line to be treated as database names. Without this option, `mysqldump` treats the first name as a database name and those following as table names.
>
>
> With `--all-databases` or `--databases`, `mysqldump` writes `CREATE DATABASE` and `USE` statements prior to the dump output for each database. This ensures that when the dump file is reloaded, it creates each database if it does not exist and makes it the default database so database contents are loaded into the same database from which they came. If you want to cause the dump file to force a drop of each database before recreating it, use the --add-drop-database option as well. In this case, `mysqldump` writes a `DROP DATABASE` statement preceding each `CREATE DATABASE` statement.

>
This helps to restore using:
```
# mysql < dump.sql
```
Instead of:
```
# mysql dbname < dump.sql
```
Upvotes: 4 <issue_comment>username_3: I had the problem, that even with applied utf-8 flags when creating the dump I could not avoid broken characters importing a dump that was created from a DB with many text columns using latin1.
Some googling and especially [this site](https://www.whitesmith.co/blog/latin1-to-utf8/) helped me to finally figure it out.
1. mysqldump with **--skip-set-charset --default-character-set=latin1** flags,
to avoid MySQL attempt of reconversion and setting a charset.
2. fix the dump by replacing the charset strings using sed on terminal
sed -i 's/latin1\_swedish\_ci/utf8mb4/g' mysqlfile.sql
sed -i 's/latin1/utf8mb4/g' mysqlfile.sql
to make sure you don't miss anything you can do grep -i 'latin1' mysqlfile.sql before step 2 - and then come up with more sed orders. Introduction to sed [here](https://www.cyberciti.biz/faq/how-to-use-sed-to-find-and-replace-text-in-files-in-linux-unix-shell/)
3. create a clean DB
CREATE DATABASE mydatabase CHARACTER SET utf8mb4 COLLATE utf8mb4\_0900\_ai\_ci;
4. apply fixed dump

Run command `svn help` in your terminal (mac app) and see available list of commands (Command list/code depends upon, type of **SVN** you've installed in your system. In general cases, all types of SVN has same commands but its better to check, available commands for your SVN)
If you've installed [`Apache - Subversion`](http://subversion.apache.org/), then here are all available commands for it.

2018/03/20 | 1,506 | 5,678 | <issue_start>username_0: I'm wondering how to do the following:
So, I have here an example table:
```
ID: Name: Occupation: Startdate: Enddate:
1 John Journalist 01/01/2000 01/01/2000
2 John Baker 01/01/2002 01/01/2004
3 John Butcher 01/01/2004 (null)
4 Mark Baker 05/03/2000 (null)
5 Petrus Lawyer 01/01/2001 01/01/2002
6 Petrus Baker 01/01/2002 (null)
7 Andre Journalist 01/01/1999 01/01/2000
8 Andre Baker 01/01/2000 (null)
```
So, here's what I want: I want to find the names of all the persons who have first been a journalist and then switched to being a baker. So, I don't want to find people who were just bakers, nor do I wanna find people who have first been a journalist, then a baker, and then went on to being a butcher. So, basically, I want the query to return the two records of Andre.
Is there a way to do this?
EDIT: I should mention that this db is not to be edited, so no inserts or anything that would alter the db in any way, what I want is as simple a select query as possible, if possible.<issue_comment>username_1: This uses a trick of your data, which is that the `enddate` of the previous occupation matches the `startdate` of the next one:
```
with candidates as (
select name, enddate from your_table
where occupation = 'Journalist'
intersect
select name, startdate from your_table
where occupation = 'Baker'
and enddate is null -- this is current record
)
select name
from candidates
/
```
This won't work for people who started as journalists, became butchers, then became bakers. But according to your comment that's not something you'd want to do.

In real life bounded date ranges commonly don't overlap. That is, the `startdate` should be `enddate+1`. After all, people generally don't start a new job at lunchtime!

I have this following code:
```
@Configuration

The overload of `SpringApplication.run(APPLICATION_CONTEXT_XML, getFullArgList(args))` is:
```
/**

* specified source using default settings.
* @param source the source to load

public static ConfigurableApplicationContext run(Object[] sources, String[] args) {

public class NiceBootApplicationWithoutDB extends AbstractBootApplication {

public static void main(String[] args) {
SpringApplication.run(AbstractBootApplication.class, getFullArgList(args));

}
```
Upvotes: 1 <issue_comment>username_2: You are right : the API of the `SpringApplication` class in the version 2 of Spring Boot doesn't provide an equivalence.
So no direct way to provide a XML Spring configuration file.
According to this [answer](https://stackoverflow.com/questions/31677553/where-do-i-put-my-xml-beans-in-a-spring-boot-application), you could annotate your Spring Boot class with [`@ImportResource`](https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/context/annotation/ImportResource.html).
```
@ImportResource("classpath:/META-INF/application-context-nodb.xml")
```
It works as `@Import` but that it imports XML spring configuration files instead of class files.
**Javadoc information** :
>
> Indicates one or more resources containing bean definitions to import.
>
>
> Like `@Import`, this annotation provides functionality similar to the

```
I've been trying for hours, I tired a lot of examples but failed.
any help will be gratefully received.
Thanks a lot.<issue_comment>username_1: Simply [match](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/String/match) everything between the two brackets:
```js
const str = 'some text(text here(possible text)text(possible text(more text)))end text';
const match = str.match(/\((.*)\)/);
console.log(match[0])
```

You might try printing the list of operations of your graph using `graph.get_operations()` and attempting to locate an appropriate-sounding node (try the first one that is printed)

2018/03/20 | 926 | 3,803 | <issue_start>username_0: Hello I'm trying to define relationships in my migrations
I'm using on delete restrict to prevent deletion of parent record when child is present. but its not working. For example I have this event table (parent) that has editions (child). I'm using event\_id in editions table
with `onDelete('restrict')` and have event\_id in my edition table..
It should restrict me on deleting from events table as long record has child record in edition tables right? but its not..
Here are the migrations of both tables
Events (parent)
```
php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateEventsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('events', function (Blueprint $table) {
//master table
$table-increments('event_id');
$table->string('name');
$table->text('full_name');
$table->text('description');
$table->tinyInteger('status');
$table->integer('created_by');
$table->integer('updated_by');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('events');
}
}
```
Editions (Child)
```
php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateEditionsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('editions', function (Blueprint $table) {
$table-increments('edition_id');
$table->integer('event_id')->unsigned();
$table->string('name');
$table->dateTime('start')->nullable();
$table->dateTime('end')->nullable();
$table->enum('stage', ['Archived', 'Cancelled', 'Closed', 'Live', 'On-site', 'Pre-event', 'Sold out'])->nullable()->default('Pre-event');
$table->tinyInteger('status');
$table->integer('created_by');
$table->integer('updated_by');
$table->timestamps();
});
Schema::table('editions', function($table) {
$table->foreign('event_id')
->references('event_id')->on('events')
->onDelete('restrict')->onUpdate('restrict');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('editions');
}
}
```<issue_comment>username_1: One thing I see missing from your foreign key definition is adding an index on it, that is a requirement for foreign keys and it might be what's caussing issues for you.
Try changing
```
$table->integer('event_id')->unsigned();
```
to
```
$table->integer('event_id')->unsigned()->index();
```
Also, you can just add the foreign key definition immediately after the column definition, no need to put it in a different `Schema::table()` block.

So make sure that you use `DELETE` not `SoftDeletes` otherwise you can add the constraint manually.

2018/03/20 | 591 | 1,643 | <issue_start>username_0: When I run the following code I get an KeyError: ('a', 'occurred at index a'). How can I apply this function, or something similar, over the Dataframe without encountering this issue?
Running python3.6, pandas v0.22.0
```
import numpy as np
import pandas as pd
def add(a, b):
return a + b
df = pd.DataFrame(np.random.randn(3, 3),
columns = ['a', 'b', 'c'])
df.apply(lambda x: add(x['a'], x['c']))
```<issue_comment>username_1: I think need parameter `axis=1` for processes by rows in [`apply`](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.apply.html):
>

```
df = df.apply(lambda x: add(x['a'], x['c']), axis=1)
print (df)
0 -0.802652
1 0.145142
2 -1.160743

```
Upvotes: 4 [selected_answer]<issue_comment>username_2: You don't even need apply, you can directly add the columns. The output will be a series either way:
```
df = df['a'] + df['c']
```
for example:
```
df = pd.DataFrame({'a': [1, 2], 'b': [3, 4], 'c': [5, 6]})
df = df['a'] + df['c']
print(df)
# 0 6
# 1 8
# dtype: int64
```
Upvotes: 0 <issue_comment>username_3: you can try this
```
import numpy as np
import pandas as pd
def add(df):
return df.a + df.b
df = pd.DataFrame(np.random.randn(3, 3),
columns = ['a', 'b', 'c'])
df.apply(add, axis =1)
```
where of course you can substitute any function that takes as inputs the columns of df.

My folder tree
```
root/
-contarats/
-proto/
some.proto
-package.json
"script": {
"contracts": "generate-some-contracts contracts/proto contracts",
}
const input = process.argv[2]
const settings = require(path.resolve(input, 'package.json'))
```<issue_comment>username_1: Are you looking for a way to iterate through directories? If so heres a synchronous function that would do that
```
function search_sync(dir) {
var results = []
var list = fs.readdirSync(dir)
list.forEach(function(file) {
file = path.resolve(dir, file)
filename = file.split('\\');
filename = filename[filename.length-1]
var stat = fs.statSync(file)
if (stat && stat.isDirectory()) results = results.concat(search_sync(file))
else if(filename == 'package.json')results.push(file)
})
return results
```
}
That will return an array of any files that are named package.json with their full file path. EG:
```
search_sync('./')
[C:\Users\User\MyNodeProject\package.json,
C:\Users\User\MyNodeProject\npm\someDependency\package.json,
C:\Users\User\MyNodeProject\npm\someOtherDependency\package.json]
```
Personally, I'd then break each line by their '\' character and see which one is closer to my root folder
Upvotes: 2 <issue_comment>username_2: Looking at your tree of directories, the `package.json` file is not in `contracts/proto`, but in `contracts`. (I assume that `contaracts` is a typo.) Changing the first argument on the command line should help:
```
generate-some-contracts contracts contracts
```
Nevertheless, you ask about the recursive search for the nearest `package.json`. NPM does it, when looking for the package root. It starts in the current directory and then follows the ancestors, until it finds a `package.json`. A function reading and parsing that `package.json`, similarly to `require`, could look like this:
```js
const { readFile } = require('fs/promises')
const { join, resolve } = require('path')
async function loadPackageJson(cwd) {
const startDir = cwd || process.env.INIT_CWD || process.cwd()
let dir = startDir, prevDir
do {
try {
const path = join(dir, 'package.json')
const content = await readFile(path, 'utf8')
return JSON.parse(content)
} catch (err) {
if (err.code !== 'ENOENT') throw err
}
prevDir = dir
dir = resolve(dir, '..')
} while (prevDir !== dir)
throw new Error(`package.json not found in ${startDir} and its ancestors`)
}
```

2018/03/20 | 1,143 | 3,743 | <issue_start>username_0: I have a filemaker database and I want to show records based on the following criteria:
Show all records in which either the owner or the user is "John" and the place is "London", "Paris" or "Amsterdam"
The first part is easy:
```
Enter Find Mode [Pause:Off]
Set Field [mydb::Owner; "John"]
New Record/Request
Set Field [mydb::User"; "John"]
Perform Find[]
```
But what about the second part? So far I have not been able to implement this. I could of course go ahead and loop through the records found and omit the ones I don't want, but there should be a better way to do this.<issue_comment>username_1: There is. You can use the Constrain Found Set after you perform your initial find.
```
Enter Find Mode [Pause:Off]
Set Field [mydb::Owner; "John"]
New Record/Request
Set Field [mydb::User"; "John"]
Perform Find[]
#Constrain the found set
Enter Find Mode [Pause:Off]
Set Field [mydb::Place; "London"]
New Record/Request
Set Field [mydb::Place; "Paris"]
New Record/Request
Set Field [mydb::Place; "Amsterdam"]
Constrain Found Set []
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: One straightforward way to create FileMaker searches is to rephrase your search-requirements in a list like this:
```
(O and L)
or
(O and P)
or
(O and A)
or
(U and L)
or
(U and P)
or
(U and A)
but not
(B and C)
```
In other words:
1. For *each case* that you want to find, you write down the criteria seperated by 'and' in one line. You can add parentheses, which are optional, but they do make it easier to read & understand the logic correctly
2. Then you separate each line with an 'or'
3. And if you have cases that you want to *exclude* from the results you write 'but not' instead of 'or', and - very importantly - you add the exclusions at the END of the list!
In your example, you could write:
```
(Owner="John" and Place="London")
or
(Owner="John" and Place="Paris")
or
(Owner="John" and Place="Amsterdam")
or
(User="John" and Place="London")
or
(User="John" and Place="Paris")
or
(User="John" and Place="Amsterdam")
```
When you have this written down, all you then have to do is:
1. Replace each criteria with the equivalent Set Field step (and otherwise ignore the 'and's)
2. Replace 'or' with a New Record/Request step
3. Replace 'but not' with the two steps New Record/Request, Omit Record
4. Put all that in an Enter Find Mode [Pause:Off] / Perform Find[] sandwich, and you are ready to run!
The example code then looks like this:
```
Enter Find Mode [Pause:Off]
Set Field [mydb::Owner ; "John"]
Set Field [mydb::Place ; "London"]
New Record/Request
Set Field [mydb::Owner ; "John"]
Set Field [mydb::Place ; "Paris"]
New Record/Request
Set Field [mydb::Owner ; "John"]
Set Field [mydb::Place ; "Amsterdam"]
New Record/Request
Set Field [mydb::User ; "John"]
Set Field [mydb::Place ; "London"]
New Record/Request
Set Field [mydb::User ; "John"]
Set Field [mydb::Place ; "Paris"]
New Record/Request
Set Field [mydb::User ; "John"]
Set Field [mydb::Place ; "Amsterdam"]
Perform Find[]
```
Whether you use this multiple-request method or username_1's constrain method is a question of performance & the quantity of combinations you have got.
For the sake of completeness, here is an example of 'but not' - with a Brexit theme:
Say you are wanting to find FileMaker programmers in continental europe, you may have the following criteria:
```
(Job="FileMaker" and Place="Europe")
but not
(Land="UK")
```
Using the above method this would then be implemented as:
```
Enter Find Mode [Pause:Off]
Set Field [mydb::Job ; "FileMaker"]
Set Field [mydb::Place ; "Europe"]
New Record/Request
Omit Record
Set Field [mydb::Land ; "UK]
Perform Find[]
```
Happy FileMaking!

I have data in my objectArrayList list. I can print it in console, but nothing is coming in recyclerview. In recyclerview, it is only displaying empty Textview.
Following way, implement recyclerview,
```
layoutManager = new LinearLayoutManager(this);
dispatchMaterialAdapter =
new DispatchMaterialAdapter(itemClickListener, dispatchMaterialMds);
recycleListDetail.setLayoutManager(layoutManager);
recycleListDetail.setAdapter(dispatchMaterialAdapter);
```
dispatchMaterialMds is an arraylist of model class which is filled from the database's data.
Can you please help me, why my data is not getting displayed ?<issue_comment>username_1: Please try this
```
@Override
public int getItemCount() {

dispatchMaterialAdapter =
new DispatchMaterialAdapter(itemClickListener, dispatchMaterialMds);
recycleListDetail.setLayoutManager(layoutManager);
recycleListDetail.setAdapter(dispatchMaterialAdapter);
dispatchMaterialAdapter.notifyDataSetChanged();
```
and also check your adapter in bind view get the arraylist value and check arraylist type in getting and passing to adapter that same or not.

Context mContext;
```
public RecyclerViewAdpater(List mStringList, Context mContext) {

}
public class ItemViewHolder extends RecyclerView.ViewHolder {
TextView textView;
public ItemViewHolder(View itemView) {
super(itemView);
textView=itemView.findViewById(R.id.timeData);

2018/03/20 | 1,077 | 3,521 | <issue_start>username_0: This is my code, we have database called "our\_new\_database".
The connection is fine, as well as the HTML Form and credentials and I still cannot insert information into the database.
Table is created, I can see the columns and lines in XAMPP / phpMyAdmin.
The only error I'm getting is the last echo of the If/Else Statement - "Could not register".
Tried everything I can and still cannot make this insertion to work normally.
Can someone advise me something?
```
php
include "app".DIRECTORY_SEPARATOR."config.php";
include "app".DIRECTORY_SEPARATOR."db-connection.php";
include "app".DIRECTORY_SEPARATOR."form.php";
$foo_connection = db_connect($host, $user_name, $user_password, $dbname);
$sql = "CREATE TABLE user_info(
user_name_one VARCHAR(30) NOT NULL,
user_name_two VARCHAR(30) NOT NULL,
user_email VARCHAR(70) NOT NULL UNIQUE
)";
if(mysqli_query($foo_connection, $sql)){
echo "Table created successfully";
}
else {
echo "Error creating table - table already exist.".mysqli_connect_error($foo_connection);
}
if($_SERVER['REQUEST_METHOD'] == 'POST'){
$user_name_one = $_POST["userOne"];
$user_name_two = $_POST["userTwo"];
$user_email = $_POST["userEmail"];
$sql = "INSERT INTO user_info (userOne,userTwo,userEmail) VALUES('".$_POST['userOne']."',('".$_POST['userTwo']."',('".$_POST['userEmail']."')";

```
$sql = "INSERT INTO user_info (userOne,userTwo,userEmail) VALUES('".$_POST['userOne']."',('".$_POST['userTwo']."',('".$_POST['userEmail']."')";
```
Do not match, it should look like something like this:
```
$sql = "INSERT INTO user_info (userOne,userTwo,userEmail) VALUES('".$_POST['userOne']."','".$_POST['userTwo']."','".$_POST['userEmail']."')";
```
Cause for know your query is:
```
"INSERT INTO user_info (userOne,userTwo,userEmail) VALUES('value',('value1',('value2')"
```
As said above you might use:
echo $foo\_connection->error
To see some errors displayed
Upvotes: 0 <issue_comment>username_3: You need to change
```
$sql = "INSERT INTO user_info (userOne,userTwo,userEmail) VALUES('".$_POST['userOne']."',('".$_POST['userTwo']."',('".$_POST['userEmail']."')";
```
To
```
$sql = "INSERT INTO `user_info`(`user_name_one`,`user_name_two`,`user_emai`l) VALUES ('$user_name_one','$user_name_two','$user_email')";
```
remember you should use prepared query
```
$sql= $foo_connection->prepare("INSERT INTO user_info
(user_name_one,user_name_two,user_email))
VALUES(?,?,?)");
$sql->bind_param('sss', $user_name_one, $user_name_two, $user_email );
$sql->execute();
```
Upvotes: 1 [selected_answer]<issue_comment>username_4: You should avoid the direct use of variables in SQL statements, instead, you should use parameterized queries.
This also should avoid the need to string concatenation and manipulation problems.
```
$stmt = $foo_connection->prepare("INSERT INTO user_info
(user_name_one,user_name_two,user_email))
VALUES(?,?,?)");
$stmt->bind_param('sss', $user_name_one, $user_name_two, $user_email );
$stmt->execute();

2018/03/20 | 1,246 | 4,480 | <issue_start>username_0: I am trying to trigger a Dataflow pipeline from a Cloud Function which itself is triggered upon upload of a new file in a GCS bucket.
When I upload a file, the Cloud function gets triggered properly but timesout after few seconds without any Dataflow being triggered.
Below is my function code:
```js
const google = require('googleapis');
const projectId = "iot-fitness-198120";
exports.moveDataFromGCStoPubSub = function(event, callback) {
const file = event.data;
if (file.resourceState === 'exists' && file.name) {
google.auth.getApplicationDefault(function (err, authClient, projectId) {
if (err) {
throw err;
}
if (authClient.createScopedRequired && authClient.createScopedRequired()) {
authClient = authClient.createScoped([
'https://www.googleapis.com/auth/cloud-platform',
'https://www.googleapis.com/auth/userinfo.email'
]);
}
console.log("File exists and client function is authenticated");
console.log(file);
const dataflow = google.dataflow({ version: 'v1b3', auth: authClient });
console.log(`Incoming data: ${file.name}`);
dataflow.projects.templates.create({
projectId: projectId,
resource: {
parameters: {
inputFile: `gs://${file.bucket}/${file.name}`,
outputTopic: `projects/iot-fitness-198120/topics/MemberFitnessData`
},
jobName: 'CStoPubSub',
gcsPath: 'gs://dataflow-templates/latest/GCS_Text_to_Cloud_PubSub',
staginglocation: 'gs://fitnessanalytics-tmp/tmp'
}
}, function(err, response) {
if (err) {
console.error("problem running dataflow template, error was: ", err);
}
console.log("Dataflow template response: ", response);
callback();
});
});
}
};
```
The execution doesn't even log the following line, console.log("File exists and client function is authenticated"); which tells me it is not even getting that far.
Here's the log output during execution:
2018-03-20 04:56:43.283 GST
DataflowTriggeringFunction
52957909906492
Function execution took 60097 ms, finished with status: 'timeout'
2018-03-20 04:55:43.188 GST
DataflowTriggeringFunction
52957909906492
Function execution started
Any idea why it's not triggering the Dataflow and yet not throwing an error message ?<issue_comment>username_1: Guess your cloud function execution fails doesn't satisfy your if statement,
```
if (file.resourceState === 'exists' && file.name)
```
I had similar issue when I started working on Cloud Function. Modify your index.js file `var {google} = require('googleapis');` as provided in the solution [here](https://stackoverflow.com/questions/49348220/google-cloud-functions-cannot-read-property-getapplicationdefault)

2018/03/20 | 2,301 | 8,677 | <issue_start>username_0: I've followed the tutorial on the angular site (<https://angular.io/guide/http>) but I can't achieve what I want since I have an error that I don't understand.
I've put my text file in the assets doc and created a config.json file where I entered the code from the tutorial.
I get errors in my service.ts file and component.ts file aswell.
Please help me understand my errors and the tutorial.
**Component.ts**
```
import { Component, OnInit } from '@angular/core';
import {Observable} from 'rxjs/Observable';
import {HttpClient, HttpErrorResponse, HttpResponse} from '@angular/common/http';
import {GeneralService} from '../general.service';
@Component({
selector: 'app-general',
templateUrl: './general.component.html',
styleUrls: ['./general.component.css']
})
export interface General {
generalUrl: string;
textfile: string;
}
export class GeneralComponent implements OnInit {
title = 'Introduction';
generalUrl = 'assets/project_description.txt';
general: General;
generalService: GeneralService;
constructor(private http: HttpClient) { }
ngOnInit() {
}
getGeneral() {
return this.http.get(this.generalUrl);
}
showGeneral() {
this.generalService.getGeneral()
.subscribe(data => this.general = {
generalUrl: data['generalUrl'],
textfile: data['textfile']
});
}
showGeneralResponse() {
this.generalService.getGeneralResponse()
.subscribe(resp => {
const keys = resp.headers.keys();
this.headers = keys.map(key =>
`${key}: ${resp.headers.get(key)}`);
this.config = {
});
}
}
```
On my showGeneralResponse() function headers and config are unresolved variables
**Service.ts**
```
import { Injectable } from '@angular/core';
import {General} from './general/general.component';
import {HttpResponse} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';
@Injectable()
export class GeneralService {
constructor() { }
getGeneral() {
return this.http.get(this.generalUrl);
}
getGeneralResponse(): Observable> {
return this.http.get(
this.generalUrl, { observe: 'response'}
);
}
}
```
In getGeneral() and getGeneralresponse() functions I have http and generalUrl who are unresolved variables
But in my config.json file I have no error
**config.json**
```
"generalUrl": "api/general",
"textfile": "assets/project_description.txt"
```
I also would like to know which function to put in my html file so my application would display me my file text<issue_comment>username_1: @<NAME>
1.- the json must be a json, see the "{" and the "
```
{
generalUrl: "api/general",
textfile: "assets/project_description.txt"
}
```
2.-You have defined the variable "generalUrl" in your component, but not in the service.
3.-If you want to use a Service in a component you must inject in the constructor
```
//In your component
//remove the line below
//generalService: GeneralService;
//And change the cosntructor
constructor(private http: HttpClient,private generalService:GeneralService) { }
```
4.-You must cal lthe function this.showGeneral() in your ngOnInit() or never happens
5.- Declare the export interface before the component
```
import { Component, OnInit } from '@angular/core';
...
//Move export inferface here
export interface General {
generalUrl: string;
textfile: string;
}
@Component({
selector: 'app-general',
templateUrl: './general.component.html',
styleUrls: ['./general.component.css']
})
export class GeneralComponent implements OnInit {
...
}
```

```
//app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {HttpClientModule} from '@angular/common/http';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
HttpClientModule
],
providers: [DataService,],
bootstrap: [AppComponent]
})
export class AppModule { }
//DataService.ts
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Injectable()
export class DataService {
constructor(private http: HttpClient) { }
getData() {
return this.http.get('../assets/data.json')
}
}
//app.compontent.ts
import { Component, OnInit } from '@angular/core';
import {DataService} from './data.service'
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
data:any;
constructor(private dataService:DataService){}
ngOnInit(){
this.dataService.getDataDos(null).subscribe(res=>{
this.data=res;
})
}
}
}
//app.component.html
{{data |json}}
//data.json (in folder assets/)
[
{"key":"uno"},
{"key":"dos"},
{"key":"tres"},
{"key":"cuatro"},
{"key":"cinco"}
]

The data and the error are available directly via these callbacks.
[A reason for existing](https://i.stack.imgur.com/XgO0e.png)
------------------------------------------------------------
When you use HttpClient with Observable, you have to use **.subscribe(x=>...)** in the rest of your code.
This is because **Observable<`HttpResponse`<`T`>>** is tied to **HttpResponse**.
This **tightly couples** the **http layer** with the **rest of your code**.
This library encapsulates the **.subscribe(x => ...)** part and exposes only the data and error through your Models.
**With strongly-typed callbacks, you only have to deal with your Models in the rest of your code.**
The library is called **angular-extended-http-client**.
[**angular-extended-http-client library on GitHub**](https://github.com/VeritasSoftware/angular-http-client-ext)
[**angular-extended-http-client library on NPM**](https://www.npmjs.com/package/angular-extended-http-client)
Very easy to use.
Sample usage
------------
The strongly-typed callbacks are
Success:
* **IObservable<`T`>**
* **IObservableHttpResponse**
* **IObservableHttpCustomResponse<`T`>**
Failure:
* **IObservableError<`TError`>**
* **IObservableHttpError**
* **IObservableHttpCustomError<`TError`>**
### Add package to your project and in your app module
```js
import { HttpClientExtModule } from 'angular-extended-http-client';
```
and in the @NgModule imports
```js
imports: [
.
.
.
HttpClientExtModule
],
```
### Your Models
```js
//Normal response returned by the API.
export class RacingResponse {
result: RacingItem[];
}
//Custom exception thrown by the API.
export class APIException {
className: string;
}
```
### Your Service
In your Service, you just create params with these callback types.
Then, pass them on to the **HttpClientExt**'s get method.
```js
import { Injectable, Inject } from '@angular/core'
import { RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.
@Injectable()
export class RacingService {
//Inject HttpClientExt component.
constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {
}
//Declare params of type IObservable and IObservableError.
//These are the success and failure callbacks.
//The success callback will return the response objects returned by the underlying HttpClient call.
//The failure callback will return the error objects returned by the underlying HttpClient call.
getRaceInfo(success: IObservable, failure?: IObservableError) {
let url = this.config.apiEndpoint;
this.client.get(url, ResponseType.IObservable, success, ErrorType.IObservableError, failure);
}
}
```
### Your Component
In your Component, your Service is injected and the **getRaceInfo** API called as shown below.
```js
ngOnInit() {
this.service.getRaceInfo(response => this.result = response.result,
error => this.errorMsg = error.className);
}
```
Both, **response** and **error** returned in the callbacks are strongly typed. Eg. **response** is type **RacingResponse** and **error** is **APIException**.
You only deal with your Models in these strongly-typed callbacks.
Hence, The rest of your code only knows about your Models.
Also, you can still use the traditional route and return Observable<`HttpResponse<`T`>`> from Service API.

How to put this values from `response.data.experience` in `experience` prop?<issue_comment>username_1: You can change the state like
```
axios({
method: 'GET',
url: 'https://example.com/dictionaries/',
headers: {
'User-Agent': 'React App/1.0 (<EMAIL>)',
'HH-User-Agent': 'React App/1.0 (<EMAIL>)',
'Content-Type':'application/x-www-form-urlencoded',
}
}).then((response) => {
console.log(response.data.experience);
this.setState({experience: response.data.experience})
}).catch(function (error) {
console.log(error);
});
```
And you can loop through the `experience` array by using this :
`{
this.state.experience.map((value, index) =>
{value.name}
)
}`

2018/03/20 | 831 | 2,926 | <issue_start>username_0: So the question is this :
we have n classes (n intervals) with start time and finish time [si , fi] and we want to find the minimum number of classrooms which we can satisfy all the classes(intervals) without any collusion
the book that I'm reading says we can solve this in O(nlogn) but i cannot find any algorithm better than O(n^2)
it says we should sort them by the starting time but doesn't say the rest of the solution, but that doesn't make any sense because before giving each class a room, shouldn't we check all the other intervals to see if we have a collusion or not? which makes it O(n^2) because for each interval we need to check all the other intervals
am i missing something ?<issue_comment>username_1: You can sort the events (an event is either the start of a class or the end of a class) by time. This will take O(n log n).
Now, keep a stack of empty rooms and go through the events in order:
* for each start event take a room from the empty stack and allocate the class to it.
* for each end event put the corresponding room back to the empty stack.
This second phase can be completed in O(n).
By keeping track of the allocations and deallocations done you can easily find the number of needed rooms and the schedule.
If you just need the number of needed rooms this can be simplified to just use a counter instead of the list of rooms. Add one for each start event and subtract 1 for each end event; keep track of the maximum.

**Second step**: Sort the `actions` array in ascending order by their time. If the times are equal then sort them by `type` in ascending order.
**Third step**: Set counter to 0, iterate through `actions` array, if it is starting type add 1 to counter, if it is finishing type subtract 1 from counter. Again, if times are equal execute finishing types first. Because you can use the same classroom as soon as the class at that room ends.
The maximum value that counter reaches is your answer.

# construct a action list:

`$route['Product/(:num)/(:any)] = 'Product/$1/$2';`
I am assuming Saffron is your `base_url` directory.

2018/03/20 | 862 | 3,233 | <issue_start>username_0: I am building a weather application with ionic 3, my problem is when the response comes back (and I know the names of its keys) when I call one of them WeatherStorm (the IDE I am using) says:
>
> property 'current\_observation' does not exist on type object"
>
>
>
but the application is working when I try it on 'localhost:8100/ionic-lab'.
Until now no problem, I took this and said that the problem is from the editor(cuz it is working and giving correct results) but when I was trying to build the app to generate apk the Windows-Command-Line and Git-Bash both complained about this error. The exact command causing me the trouble is: "ionic cordova build --release android".
Here is the call method:
```
getWeather(city, state) {
return this.http.get(this.url + '/' + state + '/' + city + '.json')
.map(res => res);
}
```
And here is the response (here comes the error at current\_observation):
```
this.weatherProvider.getWeather(
this.location.city,
this.location.state
).subscribe(weather => {
this.weather = weather.current_observation;
console.log(this.weather);
})
}).catch(()=> {
});
```
Any idea?
Thank you in advance.<issue_comment>username_1: You should also declare the type of `weather` variable so that you don't get an error.
```
this.weatherProvider.getWeather(
this.location.city,
this.location.state
).subscribe((weather : Weather) => {
this.weather = weather.current_observation;
console.log(this.weather);
})
}).catch(()=> {
});
```

So at the place where you are subscribing it will expect a value of type `Weather` and will check type accordingly.
```
getWeather(city, state): Observable {
return this.http.get(this.url + '/' + state + '/' + city + '.json')
.map(res => res);
}
// place Weather in its own file and import in places where you use it.
class Weather {
current\_observation: any;
...otherKeys
}
```
If you don't care about any of these, you can try marking the return type as `any`
```
getWeather(city, state): Observable {
return this.http.get(this.url + '/' + state + '/' + city + '.json')
.map(res => res);
}
```
Also, make sure your project and your IDE are using the same version of Typescript.

So restart your computer and `ionic serve` your project again and try this code.

.subscribe((weather) =>{
this.weather = weather["current_observation"];

```<issue_comment>username_1: the issue for you sprites not showing up is that none of your objects have a zPosition set on them. You need to layer the objects as you expect them to show in the scene.
for example...
```
background.zPosition = 1
player.zPosition = 1
enemy.zPosition = 1
bullet.zPosition = 2
scoreLabel.zPosition = 100
```
In my opinion you shouldn't be using timers to generate your enemies. Spritekit has it's own timing functionality built into the update function. Which you are already using to control the timing of the backgrounds.
You had waaaaay to much code in your question, you need to look at how I've tailored the code down to only relevant code to your question. Including all of your code in your question actually makes it more unlikely that you will get the help or answers you need because it is harder to go through all the code to figure out what is happening. Also don't include so many spaces in your code in your question scrolling through hundreds of lines even if a lot of them are spaces is very tedious.

enemy.zPosition = 3
bullets.zPosition = 2

2018/03/20 | 293 | 1,115 | <issue_start>username_0: how can I upload multiple images using a single file upload control in asp.net web forms?
I am able to upload a single image file using file upload control but I want to make it more dynamic to upload multiple images by using one control.
Can anyone help me out in this?
Thankyou.<issue_comment>username_1: You can't. It is strictly one file per control.
To upload multiple files using one submit button you would need to use Javascript to add more FileControls dynamically, like this (using jQuery):
```
$(document).ready(function () {
$("#addAnotherFile").click(function () {
$("input[type='file']").after('
');
}
});
```
In the submit button handler, you can then enumerate through the Request.Files collection to access your uploads:
```
for (int i = 0; i < Request.Files.Count; i++)
{
HttpPostedFile file = Request.Files[i];

I have already `set` **authentication json** file to the environment variable `GOOGLE_APPLICATION_CREDENTIALS`. However, I got the translateException when I run java sample code.
```
Exception in thread "main" com.google.cloud.translate.TranslateException: The request is missing a valid API key.
at com.google.cloud.translate.spi.v2.HttpTranslateRpc.translate(HttpTranslateRpc.java:61)

"message" : "The request is missing a valid API key.",
"reason" : "forbidden"
} ],
"message" : "The request is missing a valid API key.",
"status" : "PERMISSION_DENIED"
}
```
The doc shows that this JSON file contains key infomation.
The sample code is shown
```
// Instantiates a client
Translate translate = TranslateOptions.getDefaultInstance().getService();
// The text to translate
String text = "Hello, world!";
// Translates some text into Russian
Translation translation =
translate.translate(
text,
TranslateOption.sourceLanguage("en"),
TranslateOption.targetLanguage("ru"));
System.out.printf("Text: %s%n", text);
System.out.printf("Translation: %s%n", translation.getTranslatedText());
```
I have no idea how to set api-key.
It still doesn't work after I set environment variable for `key` and `credentials`.

The simplest way to authenticate is to use [Application Default Credentials](https://cloud.google.com/docs/authentication/production). These credentials are automatically inferred from your environment, so you only need the following code to create your service object:
```
Translate translate = TranslateOptions.getDefaultInstance().getService();
```
I have personally never gotten that to work.
This code can be also used with an API key. By default, an API key is looked for in the `GOOGLE_API_KEY` environment variable. Once the API key is set, you can make API calls by invoking methods on the Translation service created via `TranslateOptions.getDefaultInstance().getService()`.

CASE
when ty.type ='Catalog'

or zs.name='Leo'
AND ( CASE
when actual_finish_date is not null
then actual_finish_date

else baseline_finish_date
END ) is not null
and visibility.ty_visibility !='Private'
then 1
else 0
END as PARTICIPANT,

Now the problem is it's not checking the entire condition,it's stopping at the first line itself(ty.type='Catalog').
Even when ty\_visibility is equal to Private it's selecting the value as 1 instead of 0

I am a beginner I want to make a top bar button that has badge like the picture above, after searching on the internet, I can make the badge on the button by implementing the `SSBadgeButton` like the code below
```
import UIKit
class SSBadgeButton: UIButton {
var badgeLabel = UILabel()
var badge: String? {
didSet {
addBadgeToButon(badge: badge)
}
}
public var badgeBackgroundColor = UIColor.red {
didSet {
badgeLabel.backgroundColor = badgeBackgroundColor
}
}
public var badgeTextColor = UIColor.white {
didSet {
badgeLabel.textColor = badgeTextColor
}
}
public var badgeFont = UIFont.systemFont(ofSize: 12.0) {
didSet {
badgeLabel.font = badgeFont
}
}
public var badgeEdgeInsets: UIEdgeInsets? {
didSet {
addBadgeToButon(badge: badge)
}
}
override init(frame: CGRect) {
super.init(frame: frame)
addBadgeToButon(badge: nil)
}
func addBadgeToButon(badge: String?) {
badgeLabel.text = badge
badgeLabel.textColor = badgeTextColor
badgeLabel.backgroundColor = badgeBackgroundColor
badgeLabel.font = badgeFont
badgeLabel.sizeToFit()
badgeLabel.textAlignment = .center
let badgeSize = badgeLabel.frame.size
let height = max(18, Double(badgeSize.height) + 5.0)
let width = max(height, Double(badgeSize.width) + 10.0)
var vertical: Double?, horizontal: Double?
if let badgeInset = self.badgeEdgeInsets {
vertical = Double(badgeInset.top) - Double(badgeInset.bottom)
horizontal = Double(badgeInset.left) - Double(badgeInset.right)
let x = (Double(bounds.size.width) - 10 + horizontal!)
let y = -(Double(badgeSize.height) / 2) - 10 + vertical!
badgeLabel.frame = CGRect(x: x, y: y, width: width, height: height)
} else {
let x = self.frame.width - CGFloat((width / 2.0))
let y = CGFloat(-(height / 2.0))
badgeLabel.frame = CGRect(x: x, y: y, width: CGFloat(width), height: CGFloat(height))
}
badgeLabel.layer.cornerRadius = badgeLabel.frame.height/2
badgeLabel.layer.masksToBounds = true
addSubview(badgeLabel)
badgeLabel.isHidden = badge != nil ? false : true
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.addBadgeToButon(badge: nil)
fatalError("init(coder:) has not been implemented")
}
}
```
as we can see the `SSBadgeButton`is UIButton, and I need to convert that `SSBadgeButton` to `UIBarButtonItem`. the purpose of this is to make the `UIBarButtonItem` class to be accessible in the Interface builder as the custom class like the picture below
[](https://i.stack.imgur.com/kBJi9.png)<issue_comment>username_1: you can create `UIBarButtonItem` with custom button
```
let button = SSBadgeButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30)
let barBtnItem = UIBarButtonItem(customView: button)
```
Upvotes: 1 <issue_comment>username_2: You don't need to convert the `UIButton` to `UIBarButtonItem`, you can always create `UIBarbuttonItem` using `UIButton` as shown below
```
let button = UIButton()
button.setTitle("ABCD", for: .normal)
let uiBarButtonItem = UIBarButtonItem(customView: button)
self.navigationItem.leftBarButtonItems = [uiBarButtonItem]
```
Instead of UIButton you will use your `SSBadgeButton` thats all

2018/03/20 | 1,404 | 6,049 | <issue_start>username_0: We are developing a .Net Core 2.1 Web API with JWT Bearer authentication. The application itself will generate and hand out tokens which are to be send to the backend.
While we have everything up and running, i.e. we can send the bearer token from Angular and test it with Postman, Swagger won't send the Bearer token.
We have added the Swagger configuration to use a SecurityDefinition as followed, I will post the complete ConfigureServices method:
```
public void ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMvc();
services.AddCors(options =>
{
options.AddPolicy("AllowAllOrigins",
policy => policy.WithOrigins("*").AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod());
});
services.Configure(options =>
{
options.Filters.Add(new CorsAuthorizationFilterFactory("AllowAllOrigins"));
});
ServiceInstaller.Install(services, Configuration);
// api user claim policy
services.AddAuthorization(options =>
{
var authorizationPolicy = new AuthorizationPolicyBuilder()
.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
.RequireAuthenticatedUser().Build();
options.AddPolicy("Bearer", authorizationPolicy);
});
// add identity
var builder = services.AddIdentityCore(o =>
{
// configure identity options
o.Password.RequireDigit = false;
o.Password.RequireLowercase = false;
o.Password.RequireUppercase = false;
o.Password.RequireNonAlphanumeric = false;
o.Password.RequiredLength = 6;
});
builder = new IdentityBuilder(builder.UserType, typeof(IdentityRole), builder.Services);
builder.AddEntityFrameworkStores().AddDefaultTokenProviders();
var keyByteArray = Encoding.ASCII.GetBytes("placekeyhere");
var signingKey = new Microsoft.IdentityModel.Tokens.SymmetricSecurityKey(keyByteArray);
services.AddAuthentication(options => { options.DefaultScheme = JwtBearerDefaults.AuthenticationScheme; }).AddJwtBearer(
options =>
{
options.TokenValidationParameters = new TokenValidationParameters()
{
IssuerSigningKey = signingKey,
ValidAudience = "Audience",
ValidIssuer = "Issuer",
ValidateIssuerSigningKey = true,
ValidateLifetime = true,
ClockSkew = TimeSpan.FromMinutes(0)
};
});
// Configure JwtIssuerOptions
services.Configure(options =>
{
options.Issuer = "Issuer";
options.Audience = "Audience";
options.SigningCredentials = new SigningCredentials(signingKey, SecurityAlgorithms.HmacSha256);
});
// Register the Swagger generator, defining one or more Swagger documents
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info { Title = "AppName", Version = "v1" });
c.OperationFilter();
c.AddSecurityDefinition("Authorization", new ApiKeyScheme
{
Description =
"JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = "header",
Type = "apiKey",
});
});
}
```
This does add the Authenticate option to the top of the screen. In the configure method we tell the application to actually use the authentication:
```
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseAuthentication();
if (env.IsDevelopment())
{
// Enable middleware to serve generated Swagger as a JSON endpoint.
app.UseCors();
app.UseSwagger();
// Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.), specifying the Swagger JSON endpoint.
app.UseSwaggerUI(c => { c.SwaggerEndpoint("/swagger/v1/swagger.json", "AppName"); });
}
app.UseMvc();
}
```
However when we authenticate ourselves with a token, the curl for the function does not show the Bearer token. It looks like Swagger does not send the token to the backend.
We use .Net Core 2.1 and Swagger 2.3. Any help would be appreciated, thank you.<issue_comment>username_1: **Update - The Swagger spec has changed. check answer by @nilay below for the correct solution.**
I had the very same problem.
2 things are neccessary
1. You have to put `"bearer "` like this.
Putting only token will not work.
2.
to get this to work in swagger 2.x, you need to accompany your scheme definition with a corresponding requirement to indicate that the scheme is applicable to all operations in your API:
```
c.AddSecurityRequirement(new Dictionary>
{
{ "Bearer", new string[] { } }
});
```
Complete definition:
```
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info { Title = "Some API", Version = "v1" });
c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
{
Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = "header",
Type = "apiKey"
});
c.AddSecurityRequirement(new Dictionary>
{
{ "Bearer", new string[] { } }
});
});
```

Thank for your help.
UPDATE: SOLVED
'Pesan' should be List<><issue_comment>username_1: **Update - The Swagger spec has changed. check answer by @nilay below for the correct solution.**
I had the very same problem.
2 things are neccessary
1. You have to put `"bearer "` like this.
Putting only token will not work.
2.
to get this to work in swagger 2.x, you need to accompany your scheme definition with a corresponding requirement to indicate that the scheme is applicable to all operations in your API:
```
c.AddSecurityRequirement(new Dictionary>
{
{ "Bearer", new string[] { } }
});
```
Complete definition:
```
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info { Title = "Some API", Version = "v1" });
c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
{
Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = "header",
Type = "apiKey"
});
c.AddSecurityRequirement(new Dictionary>
{
{ "Bearer", new string[] { } }
});
});
```

```
var securityScheme = new OpenApiSecurityScheme()
{
Description = "JWT Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.Http,
Scheme = "bearer",
BearerFormat = "JWT"
};
var securityRequirement = new OpenApiSecurityRequirement
{
{
new OpenApiSecurityScheme
{
Reference = new OpenApiReference
{
Type = ReferenceType.SecurityScheme,
Id = "bearerAuth"
}
},
new string[] {}
}
};
options.AddSecurityDefinition("bearerAuth", securityScheme);
options.AddSecurityRequirement(securityRequirement);

I'm making a program where after the Javascript file does its thing, the text in the upper right hand corner of the table will be replaced with the 'sum.toFixed(2)' variable (in this case, 67.97). It works, but the problem is that the .text() method repeats itself, causing the result to become NaN, since the other numbers required to make the sum.toFixed(2) are erased after it has been added to the sum. And based on the console below, it seems that that is the cause of the problem.
[](https://i.stack.imgur.com/xbk2C.png)
[](https://i.stack.imgur.com/MDTBg.png)<issue_comment>username_1: Unfortunately, `text` is slightly unusual as compared to other jQuery methods. From [the documentation](http://api.jquery.com/text/):
>
> Get the combined text contents of each element in the set of matched elements, including their descendants, or set the text contents of the matched elements.
>
>
>
Almost every other accessor function in jQuery accesses only the **first** of the matched elements, but `text` combines all of their text.
If you want the text of only the **first** matched item, you have to do that on purpose:
```
var first = parseFloat(rows.find('.price').first().text());
// ---------------------------------------^^^^^^^^
```
Upvotes: 1 <issue_comment>username_2: I solved the problem. I added an if-else statement that checks if the sum is NaN (not a number) or not. If it is NaN, no output will be shown. But if it isn't, the output will show.
```
if (sum != sum){
}
else {
rows.find('.price').first().text(sum.toFixed(2));
}

jq -rc '.RoleDetailList

| @csv' ./output.json
```
Desired output:
```
"dev-instance-role","dev-instance-role-policy","ssm.amazonaws.com--ec2.amazonaws.com--*"
```
Current output:
```
"dev-instance-role","dev-instance-role-policy","*"
```<issue_comment>username_1: It appears that .Principal.Service is either a string or an array of strings, so you need to handle both cases. Consider therefore:
```
def to_s: if type == "string" then . else join("--") end;
```
You might want to make this more generic to make it more robust or for other reasons.
You might also want to streamline your jq filter to make it more intelligible and maintainable, e.g. by using jq variables. Note also that
```
.x.a + .x.b + x.c
```
can be written as:
```
.x | (.a + .b + .c)
```
Upvotes: 1 <issue_comment>username_2: Consider adding additional condition to check whether `.Principal.Service` is type of either `array` or `string`:
```
jq -rc '.RoleDetailList

```
CREATE TABLE `test1` (

When I run following query in **mysql 5.5**, I can see the table has a default value `'0'` for the primary key even though I've not specified it
```
CREATE TABLE `test2` (
`id` int(10),
`data` VARCHAR(50),
PRIMARY KEY (`id`)
);
```
This doesn't happen in **mariadb 10.2**.
I used to compare database structures using the values in information\_schema. But now it seems to be not possible to compare default values of 2 table columns from 5.5 and 10.2 databases. Anybody knows why this is automatically added? And a solution for this?<issue_comment>username_1: If a column definition includes no explicit DEFAULT value, MySQL determines the default values.
Upvotes: 0 <issue_comment>username_2: Since Primary key cant be NULL & cant be duplicate, MYSQL assign default value for the first record if you don't specify a value to it at the time of record insert.
You can set this primary key as auto increment and you can also insert values if you want even after it is of type auto increment ( If you Want ).
Upvotes: 0 <issue_comment>username_3: According to [MariaDB documentation](https://mariadb.com/kb/en/library/primary-keys-with-nullable-columns/) `MariaDB` before the version `10.1.7` and `MySQL` before the version `5.7` convert such columns into a NOT NULL column with a default value of 0. But then both DBs changed their behaviour and currently the column is converted to NOT NULL, but without a default value.
Thus, you can change one of your DB version to achieve the same behaviour

2018/03/20 | 1,765 | 6,566 | <issue_start>username_0: there is a table containing a column of type `SDO_GEOMETRY` representing some points. Later a spatial query like 'show all other points within distance x' shall be executed.
After pumping some data via `sqlloader` into a import-table I am going to bring these datasets into a base-table while merging if business-key still exists.
My application is a executable jar using `hibernate 5.0.9`, `hibernate-spatial 5.0.9 final`, Oracle12c database and the hibernate.dialect has been
```
org.hibernate.dialect.Oracle12cDialect
```
before but now changed to
```
org.hibernate.spatial.dialect.oracle.OracleSpatial10gDialect
```
I know that there is only a spatial-dialect oficially for Oracle10 and also testet with oracle11 but with oracle12.
The problem now is, that the objects are stored via hibernate into base-table but inside the SDO-Geometry all coordinates are null (while the sdo\_geometry object isnt).
```
select
businessKey,
my_sdo_geometry.sdo_point.x longitude,
my_sdo_geometry.sdo_point.y latitude
from my_import_table;
```
[](https://i.stack.imgur.com/6ZmH4.png)
After sqlloader, all coordinates in import-table are shown well.
[](https://i.stack.imgur.com/nWTb3.png)
But after processing each import-dataset its column 'imported' {Y, N} is set to 'Y'. And doing so I am using `myEntityManager.merge(importDataset)`. Due to this (although alle coordinates had been fine after sqlloader) the coordinates of the import-dataset are cleared to null.
```
//coordinates still viewable in database
importObject.setImported(Boolean.TRUE);
em.merge(importObject);
//coordinates null now
```
[](https://i.stack.imgur.com/R4i71.png)
I guess that the spatial dialect is not working properly.
I am afraid that this happens due to some incompatibility between last version of hibernate-spatial and oracle12c.
I am writing here with hope that there is anybody using hibernate-spatial successfully with oracle12 (to clarify that its possible at all) and to may get some help with any bad configuration on my side.
The persistance.xml of my application:
```
org.hibernate.ejb.HibernatePersistence
```
Thanks in advance.
edit:
in the entity class the sdo\_geometry column (here called 'Position') getter is annotated as follows:
```
@Column(name = "POSITION", nullable = false)
public Point getPosition() {
return this.position;
}
```
edit 2:
after enabling hibernate sql trace, I found that hibernate is trying this update:
```
Hibernate: update IMPORT_TABLE set HB_VERSION=?, BUSINESS_KEY=?, IMPORTED=?, [...], POSITION=? where IMPORT_TABLE_ID=? and HB_VERSION=?
```
I am pointing to `POSITION=?` which cannot be right I believe.
At this position I would expect the hibernate-dialect to take place.
May another hint to an imcompatibility with hibernate-dialect spatial10 and oracle12.<issue_comment>username_1: I found a workaround which is not answering my question as I intend but its a workaround so far.
Instead of using hibernate objects and the merge-operator It works when instead using a custom query like this:
```
Query q = em.createQuery("INSERT INTO base_table"
+ "(techId, myBuildingFK, [...], my_sdo_geometry) "
+ "SELECT l.impTechId, b, [...], l.my_sdo_geometry"
+ "FROM import_table l, Buildiung b "
+ "WHERE l.businessKey = g.businessKey ");
q.executeUpdate();

With this HQL-Query I am getting the coordinates not be emptied.
Due to its still a HQL Query may something of the spatial-dialect is still used but it seems it is not working properly with merge-command of entity manager. May I am missing still some annotation at the entity to get this working may its incompatible with Oracle12.
I hope still for other and may better answers than mine.
edit:
because I need merge-behaviour I thought of just merging the object via entity manager and then do an sql or hql updatequery to store the sdo\_geometry but since the transaction did not finish there is no datset to be updated.
```
// //not working
// em.merge(mergeObject);
// String updateQueryString =
// "update BaseTable set sdo_geometry = :sdoGeometry" + " where baseTableId = :baseTableId";
// Query updateQuery = em.createQuery(updateQueryString);
// updateQuery.setParameter("sdoGeometry", mergeObject.getSdoGeometry());
// updateQuery.setParameter("baseTableId", mergeObject.getBaseTableId());
// int cnt = updateQuery.executeUpdate();
```
Due to this I am now doing a native oracle merge statement which does work as expected but escapes every hibernate behaviour and is of bad architecture I think.
```
String mergeQueryString = "MERGE INTO Base_Table gl "
+ "USING (SELECT * FROM Import_Table WHERE import_table_id = :importTableId) igl "
+ "ON (gl.base_table_id = :baseTableId) "
+ "WHEN MATCHED THEN UPDATE SET gl.my_sdo_geometry = igl.my_sdo_geometry "
+ "WHEN NOT MATCHED THEN INSERT (gl.baseTableId, gl.anyFkId, gl.my_sdo_geometry) "
+ "VALUES (id_gen_function, :anyFkId, igl.my_sdo_geometry)";
Query mergeQuery = em.createNativeQuery(mergeQueryString);
mergeQuery.setParameter("importTableId", importObject.getImportTableId());
mergeQuery.setParameter("baseTableId", refModelObject.getBaseTableId());
mergeQuery.setParameter("anyFkId", refModelObject.getAnyFkObject().getAnyFkId());
int cnt = mergeQuery.executeUpdate();
```

In geolatte-geom version 1.1 or higher you should be able to set the GEOLATTE\_USE\_SDO\_POINT\_TYPE Java system property. With that property set, Point geometries will be stored in the SDO\_Geometry.SDO\_Point field. If your Hibernate version uses an older Geolatte-geom version, you may want to add a more recent version to your classpath so you can use this feature.
Btw. Hibernate Spatial works by encoding the Java Geometries to values that can be set in a prepared statement, so the "... Position=?" part in the generated SQL is fine.

```
class MyData: NSObject {
var name = ""
/// making variable optional
var params: PublicData?
func initUserWithInfo(userInfo: [String : AnyObject]) {
if let name = userInfo["name"] as? String {
self.name = name

if let params = userInfo["params"] as? ParamData {
self.params = params

2018/03/20 | 1,570 | 6,600 | <issue_start>username_0: I need to check if some value is null or not. And if its not null then just set some variable to true. There is no else statement here. I got too many condition checks like this.
Is there any way to handle this null checks without checking all method return values?
```
if(country != null && country.getCity() != null && country.getCity().getSchool() != null && country.getCity().getSchool().getStudent() != null .....) {
isValid = true;
}
```
I thought about directly checking variable and ignoring `NullpointerException`. Is this a good practice?
```
try{
if(country.getCity().getSchool().getStudent().getInfo().... != null)
} catch(NullPointerException ex){
//dont do anything.
}
```<issue_comment>username_1: No, it is generally not good practice in Java to catch a NPE instead of null-checking your references.
You can use [`Optional`](https://docs.oracle.com/javase/8/docs/api/java/util/Optional.html) for this kind of thing if you prefer:
```
if (Optional.ofNullable(country)
.map(Country::getCity)
.map(City::getSchool)
.map(School::getStudent)
.isPresent()) {
isValid = true;
}
```
or simply
```
boolean isValid = Optional.ofNullable(country)
.map(Country::getCity)
.map(City::getSchool)
.map(School::getStudent)
.isPresent();
```
if that is all that `isValid` is supposed to be checking.
Upvotes: 7 [selected_answer]<issue_comment>username_2: You could use `Optional` here, but it creates one Optional object at each step.
```
boolean isValid = Optional.ofNullable(country)
.map(country -> country.getCity()) //Or use method reference Country::getCity
.map(city -> city.getSchool())
.map(school -> school.getStudent())
.map(student -> true)
.orElse(false);
//OR
boolean isValid = Optional.ofNullable(country)
.map(..)
....
.isPresent();
```
Upvotes: 4 <issue_comment>username_3: As alternative to other fine usage of `Optional`, we could also use a utility method with a `Supplier` var-args as parameter.
It makes sense as we don't have many nested levels in the object to check but many fields to check.
Besides, it may easily be modified to log/handle something as a `null` is detected.
```
boolean isValid = isValid(() -> address, // first level
() -> address.getCity(), // second level
() -> address.getCountry(),// second level
() -> address.getStreet(), // second level
() -> address.getZip(), // second level
() -> address.getCountry() // third level
.getISO()
@SafeVarargs
public static boolean isValid(Supplier... suppliers) {
for (Supplier supplier : suppliers) {
if (Objects.isNull(supplier.get())) {
// log, handle specific thing if required
return false;
}
}
return true;
}
```
---
Suppose you would like to add some traces, you could so write :
```
boolean isValid = isValid( Arrays.asList("address", "city", "country",
"street", "zip", "Country ISO"),
() -> address, // first level
() -> address.getCity(), // second level
() -> address.getCountry(),// second level
() -> address.getStreet(), // second level
() -> address.getZip(), // second level
() -> address.getCountry() // third level
.getISO()
);
@SafeVarargs
public static boolean isValid(List fieldNames, Supplier... suppliers) {
if (fieldNames.size() != suppliers.length){
throw new IllegalArgumentException("...");
}
for (int i = 0; i < suppliers.length; i++) {
if (Objects.isNull(suppliers.get(i).get())) {
LOGGER.info( fieldNames.get(i) + " is null");
return false;
}
}
return true;
}
```

You can either:
* catch the NPE and ignore it
* check all the references manually
* use Optional as per the other answers
* use some sort of tooling like XLST
Otherwise if you have control over the domain objects, you can redesign your classes so that the information you need is available from the top level object (make `Country` class do all the null checking...)
Upvotes: 2 <issue_comment>username_5: The object-oriented approach is to put the isValid method in Country and the other classes. It does not reduce the amount of null checks, but each method only has one and you don't repeat them.
```
public boolean isValid() {
return city != null && city.isValid();
}
```
This has the assumption that validation is the same everywhere your Country is used, but typically that is the case. If not, the method should be named hasStudent(), but this is less general and you run the risk of duplicating the whole School interface in Country. For example, in another place you may need hasTeacher() or hasCourse().
Another approach is to use null objects:
```
public class Country {
public static final Country NO_COUNTRY = new Country();
private City city = City.NO_CITY;
// etc.
}
```
I'm not sure it is preferable is this case (strictly you would need a sub class to override all modification methods), the Java 8 way would be to go with Optional as method in the other answers, but I would suggest to embrace it more fully:
```
private Optional city = Optional.ofNullable(city);
public Optional getCity() {
return city;
}
```
Both for null objects and Nullable only work if you always use them instead of null (notice the field initialization), otherwise you still need the null checks. So this option avoid null, but you code becomes more verbose to reduced null checks in other places.
Of course, the correct design may be to use Collections where possible (instead of Optional). A Country has a set of City, City has a set of Schools, which has set of students, etc.
Upvotes: 3 <issue_comment>username_6: You could also look at vavr's Option which as the below posts describes is better than Java's Optional and has a much richer API.

2018/03/20 | 629 | 2,186 | <issue_start>username_0: I've searched around for a while now on how to generate a shortened url (e.g. how bit.ly or goo.gl work) but have been unsuccessful.
I presumed it would be something like:
```
baseN(hash(long_url))
```
But I always end up with a very long digest instead of something short like 6 characters.
Is it safe to just truncate the digest before encoding it (is encoding it even necessary - I believe it is for making it URL 'safe' but wanted to ask) and is there not a possibility of collisions when only dealing with six characters?
It seems like (warning: I don't know maths) a factorial of 6! (e.g. `6*5*4*3*2*1`) would result in only 720 combinations.
I also remember reading somewhere that with a hash table of 100k items, that a rough calculation for the number of collisions could yield ~17% chance of collision. That feels like a pretty large percentage to me?
The following Python code is based off my understanding of how I might do this type of url shortening:
```
import hashlib, base64
message = hashlib.sha512()
message.update("https://www.python.org/dev/peps/pep-0537/")
base64.urlsafe_b64encode(
message.hexdigest().encode("utf-8")
)[:6].decode("utf-8")
```<issue_comment>username_1: There is no effective function to do this. You need to:
1. Store the URL in a database
2. Generate a unique ID (or if you already have the url, reuse the id)
Upvotes: 2 <issue_comment>username_2: you may be looking for a bidirectional function as mentioned in [How to code a URL shortener?](https://stackoverflow.com/questions/742013/how-to-code-a-url-shortener#742047)

a much simpler approach would be to just keep record of what you've mapped:

The definition of the "regular file" is ambiguous for me.
On the terminal, I did
```
$ touch afile
$ ln -fs afile LN-FILE
```
Then, I executed the following script (check\_file\_exist\_180320\_exec)

#!/usr/bin/env bash
if [ -e LN-file ]
then
echo "file exists [-e]"
fi
if [ -f LN-file ]
then
echo "file exists [-f]"
fi
```
For CentOS and Ubuntu, both show -e and -f for symbolic linked file (LN-FILE).
However, ls -l returns `l:symbolik link` (not `-:regular file`) identifiers for the LN-FILE file.
( see. <https://linuxconfig.org/identifying-file-types-in-linux>)

Basically when you do `-f LN-file` , and LN-file is a symbolic link, the `-f` test will follow that symlink, and give you the result of what the symlink points to.
If you want to check if a file is a symlink or a regular file, you need to do e.g.
```
if [ -h LN-file ]
then
echo "file is a symlink [-h]"
elif [ -f LN-file ]
then
echo "file is a regular file [-f]"
fi

**Or**, in Ganache (GUI), click the gear in the upper right corner and change the port number from `7545` to `8545`, then restart. With ganache-cli use `-p 8545` option on startup to set 8545 as the port to listen on.
Either way, the mismatch seems to be the issue; these numbers should match. This is a common issue.

My plan is to read a file to `MemoryStream` and edit it as `WordprocessingDocument` and then returning `MemoryStream as Byte[]`.
I have two problems here:
1. If I read `WordprocessingDocument` directly from file without memory stream, I don't see a way to transform it to the shape `FileResult()` wants.
2. If I create new `WordprocessingDocument` with empty `MemoryStream` I can simply create content and return it as `File` but I lack the previously prepared header with desired content.
So, how to edit a `.docx` template and return it as `FileResult()`?<issue_comment>username_1: This is how you go about creating a new spreadsheet document with `MemoryStream` and then saving it to a `Byte[]`
```
Byte[] file;
using (MemoryStream mem = new MemoryStream())
{
using (SpreadsheetDocument spreadsheetDocument =
SpreadsheetDocument.Create(mem, SpreadsheetDocumentType.Workbook))
{
WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
workbookpart.Workbook = new Workbook();
WorksheetPart worksheetPart = workbookpart.AddNewPart();
worksheetPart.Worksheet = new Worksheet(new SheetData());
Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.
AppendChild(new Sheets());
Sheet sheet = new Sheet()
{
Id = spreadsheetDocument.WorkbookPart.
GetIdOfPart(worksheetPart),
SheetId = 1,
Name = "aStupidSheet"
};
sheets.Append(sheet);
workbookpart.Workbook.Save()
spreadsheetDocument.Close();
}
file = mem.ToArray();
}
```

So the desired "workflow" is:
1. copy `.docx` template (added headers or other things) to memory
2. edit content of the document
3. return this document as `FileResult` without saving the changes to template
So here is the code:
```
public FileResult EditDOCXBody()
{
// Prepare file path
string file = "../WordTemplates/EmptyTemplate.docx";
String fullFilePath = HttpContext.ApplicationInstance.Server.MapPath(file);
// Copy file content to MemeoryStream via byte array
MemoryStream stream = new MemoryStream();
byte[] fileBytesArray = System.IO.File.ReadAllBytes(fullFilePath);
stream.Write(fileBytesArray, 0, fileBytesArray.Length); // copy file content to MemoryStream
stream.Position = 0;
// Edit word document content
using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(stream, true))
{
MainDocumentPart mainPart = wordDoc.MainDocumentPart;
Body body = mainPart.Document.Body;
// add some text to body
body.Append(new Paragraph(
new Run(
new Text("Current time is: " + DateTime.Now.ToLongTimeString()))));
// Save changes to reflect on stream object
mainPart.Document.Save();
}
return File(stream.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "servedFilename.docx");
}
```
Some important notes:
* you need to write file bytes to MemoryStream manually otherwise you get **Memory stream is not expandable** error. More info [here](https://stackoverflow.com/questions/20589020/adding-to-wordprocessingdocument-opened-from-memorystream-without-getting-memor)
* you have to use `mainPart.Document.Save()` for changes to take effect on `MemoryStream`
* when returning the file, you have to use `.ToArray()` otherwise the returned file is corrupted

Take a look at the `HijrahChronology`, `HijrahDate` and `HijrahEra` classes, perhaps you can get some ideas and see how all the math is done to convert between this calendar and ISO8601 calendar.
But honestly, IMO calendars implementations are too complex and in most cases are not worth the trouble to do it by yourself. That's one of the cases where adding a library is totally worth it.
Using the [ThreeTen-Backport lib](http://www.threeten.org/threetenbp/) - and [configuring it to use with Android](https://stackoverflow.com/questions/38922754/how-to-use-threetenabp-in-android-project) - will give you an easy way to convert the dates and also to format them:
```
// get ISO8601 date (the "normal" date)
int dayOfMonth = 20;
int monthOfYear = 3;
int year = 2018;
// March 20th 2018
LocalDate dt = LocalDate.of(year, monthOfYear, dayOfMonth);
// convert to hijrah
HijrahDate hijrahDate = HijrahDate.from(dt);
// format to MM/DD/YYYY
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("MM/dd/yyyy");
String formatted = formatter.format(hijrahDate); // 07/03/1439
```
You can also call `HijrahDate.now()` to directly get the current date.
And you can convert the `hijrahDate` back to a "normal" date with `LocalDate.from(hijrahDate)`.
---
You can also use [time4j](http://time4j.net/):
```
// get ISO8601 date (the "normal" date)
int dayOfMonth = 20;
int monthOfYear = 3;
int year = 2018;
PlainDate dt = PlainDate.of(year, monthOfYear, dayOfMonth);
// convert to Hijri, using different variants
HijriCalendar hijriDateUmalqura = dt.transform(HijriCalendar.class, HijriCalendar.VARIANT_UMALQURA);
HijriCalendar hijriDateWest = dt.transform(HijriCalendar.class, HijriAlgorithm.WEST_ISLAMIC_CIVIL);
// format to MM/DD/YYYY
ChronoFormatter fmt = ChronoFormatter.ofPattern("MM/dd/yyyy", PatternType.CLDR, Locale.ENGLISH, HijriCalendar.family());
String formatted = fmt.format(hijriDateUmalqura); // 07/03/1439
// get current date
HijriCalendar now = HijriCalendar.nowInSystemTime(HijriCalendar.VARIANT\_UMALQURA, StartOfDay.MIDNIGHT);
// convert back to "normal" date
PlainDate date = hijriDateUmalqura.transform(PlainDate.class);
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: Taking into account your statement given in one comment that **you only want a native solution and reject any extra library**, I would advise to use ICU4J-class [IslamicCalendar](https://developer.android.com/reference/android/icu/util/IslamicCalendar.html).
Sure, you have then to accept two major disadvantages:
* API-level 24 (not so widespread on mobile phones)
* Old-fashioned API-style (for example not immutable)
Another disadvantage (which is only relevant if you are also interested in the clock time) is the fact that ICU4J does not support the start of Islamic day in the evening at sunset on previous day. This feature is only supported in my lib Time4J, nowhere else. But you have probably no need for this feature in a date picker dialog.
Advantages:
* API-style similar to what is "traditional" in package `java.util`, so I assume that you are got accustomed to it (but many/most people see the style rather as negative, you have to make your own decision)
* at least [umalqura-variant](https://developer.android.com/reference/android/icu/util/IslamicCalendar.CalculationType.html)-variant of Saudi-Arabia is offered (note: other libs like Threeten-BP or Joda-Time-Android do NOT offer that variant)
* acceptable or even good degree of internationalization (also better than in ThreetenBP or Joda-Time-Android)
For completeness, if you are willing to restrict your Android app to level 26 or higher only then you can also use [java.time.chrono.HijrahChronology](https://developer.android.com/reference/java/time/chrono/HijrahChronology.html). But I think this is still too early in year 2018 because the support of mobile phones for level 26 is actually very small. And while it does offer the Umalqura variant (of Saudi-Arabia), it does not offer any other variant.
Else there are no native solutions available. And to use only native solutions is a restriction, too, IMHO.

```<issue_comment>username_1: a) Both gotoxy not outputting via std::cout are not thread safe /synchronized. You need process-wide mutex to synchronize that
b) exception is likely due to fact that you do not use `WaitForMultipleObjects` in main to wait for threads to finish. Depending on hardware and optimization main may exit before threads finish their work.
Upvotes: 0 <issue_comment>username_2: All of these solutions in comments including mine are definitely not the way how it should be done. The main problem is lack of synchronization between threads and lack of processing their termination. Also, every function should be checked for thread-safe compatibility or should be wrapped to match it.
Considering `std::cout` since c++11 we have some data race guarantees:
>

So lask of synchronization primitives is oblivious according to this note.
Considering processing of thread termination.
```
HANDLE threadH = CreateThread(...);
...
TerminateThread(threadH, 0); // Terminates a thread.
WaitForSingleObject(threadH, INFINITE); // Waits until the specified object is in the signaled state or the time-out interval elapses.
CloseHandle(threadH); // Closes an open object handle.
```
[TerminateThread()](https://msdn.microsoft.com/en-us/library/windows/desktop/ms686717(v=vs.85).aspx), but be aware of this solution, [because ..](https://stackoverflow.com/questions/10737417/kill-a-running-thread)
[WaitForSingleObject()](https://msdn.microsoft.com/en-us/library/windows/desktop/ms687032(v=vs.85).aspx)
And this is only first steps to thread-safe way.
I would like to recommend C++ Concurrency in Action: Practical Multithreading by <NAME> for further reading.

```
SELECT
LISTAGG (case,'+') WITHIN GROUP (ORDER BY case) case,
ACC
FROM TEST
GROUP BY ACC
```
Them you will be able to count:
```
SELECT case, count(*) FROM (
SELECT

ACC
FROM TEST
GROUP BY ACC
) GROUP BY case
ORDER BY CASE;

2018/03/20 | 1,577 | 6,310 | <issue_start>username_0: I have two tables that I want to join.
Both tables are containing some varchar columns that I use to join them.
However, running queries to make calculations using varchar columns in order to join, is a slow process.
So, I would like to transform these varchar columns to unique integer ids so the comparison will be faster.
```
SELECT /*do calculations*/
FROM [dbo].[messages] m WITH (NOLOCK)
JOIN [dbo].[jointable] j ON j.address = m.orig OR j.address = m.recip
```
The address, orig and recip are the column which have strings and would be better to have ids to make performance faster.
I realise that the part `ON j.address = m.orig OR j.address = m.recip` slows performance.
The tables that i want to join have the following structure:
```
CREATE TABLE [dbo].[jointable](
[displayname] [nvarchar](256) NULL,
[alias] [nvarchar](129) NULL,
[firstname] [nvarchar](129) NULL,
[lastname] [nvarchar](129) NULL,
[address] [nvarchar](256) NULL,
[company] [nvarchar](129) NULL,
[department] [nvarchar](129) NULL,
[office] [nvarchar](129) NULL)
CREATE TABLE [dbo].[messages](
[messageid] [bigint] NOT NULL,
[message] [varchar](150) NULL,
[orig] [nvarchar](256) NULL,
[recip] [nvarchar](256) NULL)
```
How can I do this? Is there any function that I can convert an id from varchar to integer? Thank you in advance.<issue_comment>username_1: 1. [Normalize](https://en.wikipedia.org/wiki/Database_normalization) data in your tables
2. Add int primary key to the first table
3. Add int foreign key to the second table. Set corresponding value from the first table
4. Join by int keys
Upvotes: 3 [selected_answer]<issue_comment>username_2: First try to add indexes on your columns (even if they are `VARCHAR`). If you are still struggling with performance, you can use the following to join by integer values.
```
-- Create a table to link a varchar with an integer
CREATE TABLE WordIndex(
WordID INT IDENTITY PRIMARY KEY,
Word VARCHAR(500))
CREATE NONCLUSTERED INDEX NCI_WordIndex_Word ON WordIndex (Word)
GO
-- Load the table with all available words
INSERT INTO WordIndex (
Word)
SELECT DISTINCT
YourVarcharColumn
FROM
YourTable
UNION
SELECT DISTINCT
YourOtherVarcharColumn
FROM
YourSecondTable
GO
-- Add the integer ID to your tables
ALTER TABLE YourTable ADD WordID INT
ALTER TABLE YourSecondTable ADD WordID INT
ALTER TABLE YourTable ADD FOREIGN KEY (WordID) REFERENCES WordIndex (WordID)
ALTER TABLE YourSecondTable ADD FOREIGN KEY (WordID) REFERENCES WordIndex (WordID)
GO
-- Optionally (but recommended) add indexes on the ID
CREATE NONCLUSTERED INDEX NCI_YourTable_WordID ON YourTable (WordID)
CREATE NONCLUSTERED INDEX NCI_YourSecondTable_WordID ON YourSecondTable (WordID)
GO
-- Update the integer ID
UPDATE T SET
WordID = W.WordID
FROM
YourTable AS T
INNER JOIN WordIndex AS W ON T.Word = W.Word
UPDATE T SET
WordID = W.WordID
FROM
YourSecondTable AS T
INNER JOIN WordIndex AS W ON T.Word = W.Word
GO
-- Join by integer
SELECT
1
FROM
YourTable AS T
INNER JOIN YourSecondTable AS N ON T.WordID = N.WordID
```
Using this approach requieres maintaining the word index table.

If your strings are short and unique within 16 bytes this might work for you:
```
DECLARE @tbl TABLE(SomeString VARCHAR(100),TheGUID UNIQUEIDENTIFIER);
--a GUID is a 16-Byte(128 bit) sized type
INSERT INTO @tbl(SomeString) VALUES
('test1')
,('Some short text')
,('Some very very very very long text')
,('Some very very very very long text which is the same as the other one in the first 16 bytes');
UPDATE @tbl SET TheGUID=CAST(CAST(SomeString AS VARBINARY(16)) AS UNIQUEIDENTIFIER);
SELECT SomeString
,TheGUID
,CAST(CAST(TheGUID AS VARBINARY(16)) AS VARCHAR(16))
FROM @tbl;
```
The result (scroll to the side)
```
+---------------------------------------------------------------------------------------------+--------------------------------------+--------------------+
| SomeString | TheGUID | (<NAME>) |
+---------------------------------------------------------------------------------------------+--------------------------------------+--------------------+
| test1 | 74736574-0031-0000-0000-000000000000 | test1 |

If you just add int for the relationship and properly assign the int the problem is if you later change the data then the int relationship is wrong.
If you index those columns a varchar join is not much faster than int.
Would likely be the same query plan but
```
SELECT /*do calculations*/
FROM [dbo].[messages] m
JOIN [dbo].[jointable] j ON j.address in (m.orig, m.recip)
```

2018/03/20 | 807 | 2,699 | <issue_start>username_0: I want to create a local inverted theme (modern browsers). Color shades are set using CSS Vars (CSS custom properties). Some elements have more contrast, others are low contrast. Now the inverted container has a black background. Everything within there, should be reversed. Dark grey should be light grey. Light grey should be dark grey.
My goal is to achieve this without reassigning the vars in CSS selectors. For this example it would be easy, but the actual code base is big and there are many selectors. So instead of that I just want change the CSS Vars. Also, I want keep the original CSS Vars to be editable.
**Final goal mockup**
[](https://i.stack.imgur.com/ogNlx.png)
Simple reassignment of the Vars (light = dark, dark = light) does not work, obviously. I tried to transpose the values to a new placeholder var, but that also didn't worked. *Maybe I was doing it wrong?* Is there a clean way? I don't think so.
I am aware of workarounds using SASS, or hacks using mix-blend-mode.
**Playground**:
<https://codepen.io/esher/pen/WzRJBy>
**Example code:**
```
high contrast
low contrast
high contrast
low contrast
```<issue_comment>username_1: What about something like this:
```css
:root {
--high-contrast: var(--high);
--low-contrast: var(--low);
--high: #222;
--low: #aaa;
/* Yes I can put them at the end and it will work, why?
Because it's not C, C++ or a programming language, it's CSS
And the order doesn't matter BUT we need to avoid
cyclic dependence between variables.
*/
}
.high-contrast {
color: var(--high-contrast)
}
.low-contrast {
color: var(--low-contrast)
}
.inverted {
--high-contrast: var(--low);
--low-contrast: var(--high);
}
```
```html
high contrast
low contrast
high contrast
low contrast
```

```
.light {
--invert:invert(100%);
}
.dark {
--invert:invert(0%);
}
div {
filter:var(--invert)
};
```
wheither your `div` is associated to `.dark` or `.light` class you'll get the desired invertion.
```js
const button = document.getElementById('toggle');
let theme = 'dark';
button.addEventListener('click', () => {
const div = document.getElementsByTagName('div')[0];
div.classList.toggle(theme === 'dark' ? 'light' : 'dark');
})
```
```css
.dark{
--invert:invert(100%)
}
.light{
--invert:invert(0%)
}
.to-invert {
height:100px;
width:100px;
background-color:blue;
filter:var(--invert);
margin-bottom:1rem;
}
```
```html
Invert

GROUP BY sales.customer_id,times.the_year
```
am getting this error:#1054 - Unknown column 'income' in 'where clause'<issue_comment>username_1: income is alias name,so can't use that in where condition.

```
SET @limit=50;
SELECT customers.`fname`, customers.`lname` ,ROUND(SUM(sales.store_sales)) as income,times.the_year
FROM `sales`
LEFT JOIN times
ON sales.time_id=times.time_id
LEFT JOIN customers
ON customers.customer_id=sales.customer_id
WHERE `total_children`=0
GROUP BY customers.customer_id,times.the_year
having income>@limit
```
Upvotes: 1 <issue_comment>username_3: The quantity you aliased as `income` is an aggregate, and therefore it does not make sense to refer to it in the `WHERE` clause. Move this `WHERE` logic to a `HAVING` clause:
```
SET @limit=50;
SELECT
c.fname,
c.lname,
ROUND(SUM(s.store_sales)) AS income,
t.the_year
FROM sales s
LEFT JOIN times t
ON s.time_id = t.time_id
LEFT JOIN customers c
ON c.customer_id = s.customer_id
WHERE
total_children = 0
GROUP BY
c.customer_id,
t.the_year
HAVING
ROUND(SUM(s.store_sales)) > @limit;
```
Note that technically we could have used the alias in the `HAVING` clause:
```
HAVING income > @limit;
```
But this would not be portable to most other databases. Also, I introduced aliases into the query, which make it easier to read.

Are you sure you don't want a simple query like this?
```
SELECT *
FROM customers AS c
WHERE yearly_income > @limit -- but why is yearly_income a VarChar(50)?
AND total_children=0

2018/03/20 | 696 | 1,960 | <issue_start>username_0: In my case I have a list of dicts that contains other several list of dicts.
```
l = [{
'a': [
{ 'b': 4}
]
}, {
'a': [
{ 'b': 3}
]
}]
```
What I would technically like to do would be to sort using the path ['a'][0]['b'] using the sort filter of jinja2.
Is it possible in someway?<issue_comment>username_1: You can write your custom template filter.
<http://jinja.pocoo.org/docs/dev/api/#custom-filters>
Here would be a rough solution (no support for reverse, case sensitive, etc.):
Somwhere in your app:
```
def deep_sort(value, attribute, subattribute):
return sorted(value, key=lambda element: element[attribute][0][subattribute])
environment.filters['deep_sort'] = deep_sort
```
And in your template:
```
{% for value in l|deep_sort('a', 'b') %}
{{value['a'][0]['b']}}
{% endfor %}
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: You can try this in one line if you want:
```
l = [{
'a': [
{ 'b': 4}
]
}, {
'a': [
{ 'b': 9}
]
},
{
'a': [
{ 'b': 3}
]
}]
print(sorted(l,key=lambda x:x['a'][0]['b']))
```
output:
```
[{'a': [{'b': 3}]}, {'a': [{'b': 4}]}, {'a': [{'b': 9}]}]
```
Explanation :
Using lambda you can access b's values , so basically sorted() will sort basis on a list of int here how:
```
print(list(map(lambda x:x['a'][0]['b'],l)))
```
output:
```
[4, 9, 3]
```
sorted() will sort basis on this list.
Upvotes: -1 <issue_comment>username_3: You can use the `attribute` parameter in [`sort`](https://jinja.palletsprojects.com/en/3.0.x/templates/#jinja-filters.sort), where you specify `0` as the first element in the list then `b` as the key of that element, and in your case you have `attribute="a.0.b"`:
```py
your_document_list = [{
'a': [
{ 'b': 4}
]
}, {
'a': [
{ 'b': 3}
]
}]
```
```
{% for document in your_document_list | sort(attribute="a.0.b") %}
...
{% endfor %

2018/03/20 | 627 | 2,509 | <issue_start>username_0: I am working on angular 2 project and I am having an issue when I am trying to change the list . NgFor not recognizing the changes , and displaying only the list loaded at first time .
here is an example code when I am loading all list and imminently after loading I reset it with null . the view still displaying all the list ...
this is my component constructor for example :
```
constructor( private songService : SongService)
this.songService.getSongs()
.subscribe(songsList => {
this.songs = songsList;
});
this.songs = null;
}
```
and this is the html :
```
```<issue_comment>username_1: Instead of null you should set an empty array, also have it inside a method, otherwise it never gets called
```
this.songService.getSongs()
.subscribe(songsList => {
this.songs = songsList;
});
clear(){
this.songs = [];
}
```
Upvotes: 1 <issue_comment>username_2: Try this
```
constructor(private songService: SongService) {
this.songService.getSongs()
.subscribe(songsList => {
this.songs = songsList;
this.reset();
});
}
reset() {
this.songs = [];
}
```
Upvotes: -1 <issue_comment>username_3: The reason why you are still seeing your list is because it is async. You can't be sure when the subscribe method is executed. It can be be direct, within seconds, take hours or not even at all. So in your case you are resetting the list before you are even getting one.
```
constructor( private songService : SongService)
this.songService.getSongs()
.subscribe(songsList => { //Might take a while before executed.
this.songs = songsList;
});
this.songs = null; //executed directly
}
```
The above explanation might be the cause of your problem, but there could also be another explanation. The constructor is only called when the component is created. Changing a router parameter doesn't necessarily create a component. Angular might re-use the component if it can.
Upvotes: 2 <issue_comment>username_4: Loops in Angular sometimes screw up, in the way that they don't track your items the way you would want it to.
To prevent that, you can use a custom track by function like this
```
```
In your TS
```
customTB(index, song) { return `${index}-${song.id}`; }
```
This way, you set up a custom trackBy function, that will update your view (the view wasn't getting updated because the tracking ID wasn't changing).

2018/03/20 | 450 | 1,079 | <issue_start>username_0: The objective of task required to produce an array output such that `output[i]` is equal to the sum of all the elements of nums except `nums[i]`.
Eg: given `[6,7,8,9]`, return `[24,23,22,21]`.
`Input = [6,7,8,9]`
The calculation behind is
```
0+7+8+9 = 24
6+0+8+9 = 23
6+7+0+9 = 22
6+7+8+0 = 21
Output = [ 24, 24, 22, 21 ]
```<issue_comment>username_1: You can use list comprehension:
```
In [1]: a = [6,7,8,9]
In [2]: s = sum(a)
In [3]: [s - i for i in a]
Out[3]: [24, 23, 22, 21]
```
Upvotes: 2 <issue_comment>username_2: Use `numpy` broadcasting + vectorised operations for this:
```
import numpy as np
x = np.array([6,7,8,9])
y = np.sum(x) - x
# array([24, 23, 22, 21])
```
Upvotes: 1 <issue_comment>username_3: You can use a for loop and python's inbuilt sum function
```
a = [6,7,8,9] #your input array
b = [] # initialise an empty list
for index in range(len(a)): #iterate through the list's length
b.append( sum( a[0:index] + a[index+1:] ) ) #add to two parts before and
# after the index
print(b)

2018/03/20 | 1,141 | 3,956 | <issue_start>username_0: I'm trying to create a script to download subtitles from one specific website. Please read the comments in the code.
Here's the code:
```
import requests
from bs4 import BeautifulSoup
count = 0
usearch = input("Movie Name? : ")
search_url = "https://www.yifysubtitles.com/search?q="+usearch
base_url = "https://www.yifysubtitles.com"
print(search_url)
resp = requests.get(search_url)
soup = BeautifulSoup(resp.content, 'lxml')
for link in soup.find_all("div",{"class": "media-body"}): #Get the exact class:'media-body'
imdb = link.find('a')['href'] #Find the link in that class, which is the exact link we want
movie_url = base_url+imdb #Merge the result with base string to navigate to the movie page
print("Movie URL : {}".format(movie_url)) #Print the URL just to check.. :p
next_page = requests.get(movie_url) #Soup number 2 begins here, after navigating to the movie page
soup2 = BeautifulSoup(next_page.content,'lxml')
#print(soup2.prettify())
for links in soup2.find_all("tr",{"class": "high-rating"}): #Navigate to subtitle options with class as high-rating
for flags in links.find("td", {"class": "flag-cell"}): #Look for all the flags of subtitles with high-ratings
if flags.text == "English": #If flag is set to English then get the download link
print("After if : {}".format(links))
for dlink in links.find("td",{"class": "download-cell"}): #Once English check is done, navigate to the download class "download-cell" where the download href exists
half_dlink = dlink.find('a')['href'] #STUCK HERE!!!HERE'S THE PROBLEM!!! SOS!!! HELP!!!
download = base_url + half_dlink
print(download)
```
I'm getting the following error :
```
File "C:/Users/PycharmProjects/WhatsApp_API/SubtitleDownloader.py", line 24, in
for x in dlink.find("a"):
TypeError: 'NoneType' object is not iterable
```<issue_comment>username_1: Just change the above line this:
`for dlink in links.find("td",{"class": "download-cell"}):`
to this:
```
for dlink in links.find_all("td",{"class": "download-cell"}):
```
because you are running a loop on an single element rather than a list.
**Note:** The only difference is that find\_all() returns a list containing the single result, and find() just returns the result.
Hope this will helps you! :)

So, you don't need to loop over the `find()` function to get the tags. You need to make the following changes in your code (removed the unnecessary `for` loops):
```
...
# Previous code is the same
soup2 = BeautifulSoup(next_page.content,'lxml')
for links in soup2.find_all("tr",{"class": "high-rating"}):
if links.find("td", {"class": "flag-cell"}).text == "English":
print("After if : {}".format(links))
half_dlink = links.find('td', {'class': 'download-cell'}).a['href']
download = base_url + half_dlink
print(download)
```
