2018/03/20 | 1,213 | 4,125 | <issue_start>username_0: I have XML similar in structure to the below example stored in a Camel header as a String:
```
xxx
aaa
bbb
ccc
John
4324234
New Book
dsdaassda
...
...
```
I would like to extract the library element into another Camel header
```
xxx
aaa
bbb
ccc
```
How can I achieve this using Camel Java DSL?
(My main source of confusion is applying the XPath to an exchange header item rather than the body)<issue_comment>username_1: This should work:
```
.xpath("[your XPath expression]", "[the name of the header to select from]")
```
Your use case could be done like this
```
from("direct:input")
.setHeader("newHeader").xpath("[your XPath]", "[xmlHeader]")
.to("...");
```
You can find this also in the [Camel docs](http://camel.apache.org/xpath.html), Section `Using XPath on Headers`.
And it is for example used in this [Camel unit test](https://github.com/apache/camel/blob/master/camel-core/src/test/java/org/apache/camel/builder/xml/XPathHeaderNameTest.java), in the route at the bottom of the file.

```
@Override
public void configure() throws Exception {
XPathExpression xPathExpression = new XPathExpression();
xPathExpression.setHeaderName("completexml"); //assuming the header name of the xml as completexml
xPathExpression.setExpression("/list/library");
from("direct:abc")
.setHeader("OriginalBody", simple("${body}")) //get original body
.split(xPathExpression) //split according to xPathExpression
.setHeader("library", simple("${body}")) //set new header with only library element
.setBody(simple("${header.OriginalBody}")) //set the original body back
//.log("${header.completexml}")
//.log("${header.library}")
//.log("${body}")
;
}
```
As per the answer [here](https://stackoverflow.com/questions/18483320/in-camel-how-can-i-split-a-route-using-xpath-on-a-header), we could give a second argument to xpath which is of type `String`. But With the latest version, I don't see any such method in xpath which takes a second argument as String. May be it is removed in newer versions.
What I am doing is storing the original body in a header(since after split, original body is replaced by the result of split), then replacing it.

```
@Override
protected RouteBuilder createRouteBuilder() {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start")
.routeId("xpathTest")
.log(LoggingLevel.INFO, "XML input : \n${body}")
.setHeader("XNODE").xpath("/list/library", NodeList.class)
.setBody().xpath("/list/library", NodeList.class)
.to("log:end?level=INFO&showAll=true&multiline=true");
}
};
}
```
Оutput log:
```

So for the header you need an expression:
```
.setHeader("XNODE").xpath("/list/library", NodeList.class)
```
and for the body:
```
.setBody().xpath("/list/library", NodeList.class)
```

```
.setHeader("yourHeaderName", xpath("//*[local-name()='library']").stringResult())
```

{'message-ids' //this is your key that ties to the value

Long running task is executed after user receives the response.

How can I parse this payload to variables? I see this doc <https://wso2-extensions.github.io/siddhi-map-xml/api/4.0.11/> but i don't know, how get incoming wso2event to sourcemapper and then pars it to variables?<issue_comment>username_1: **siddhi-map-\*** extensions are used to map input/output event attributes at the source/sink level.
Since this xml payload is an attribute of another stream, you can use **siddhi-execution-map** extension to create a map from that xml.
Then you can handle the xml payload as a hashmap within the siddhi app.
Please refer to the documentation[1] for more details on this.

Upvotes: 3 [selected_answer]<issue_comment>username_2: Ok, I realized, that there is bug in <https://wso2-extensions.github.io/siddhi-execution-map/api/latest/> **createFromXML** function. This function correctly parse xml file over each element, but there is badly defined HashMap, because function is called recursively and every cycle is created new map and override data in old map. So at the end, there is map with only one key.
```
private Object getMapFromXML(OMElement parentElement) throws XMLStreamException {
Map topLevelMap = new HashMap();
Iterator iterator = parentElement.getChildElements();
while (iterator.hasNext()) {
OMElement streamAttributeElement = (OMElement) iterator.next();
String key = streamAttributeElement.getQName().toString();
Object value;
if (streamAttributeElement.getFirstElement() != null) {
value = getMapFromXML(streamAttributeElement);
} else {
logger.info("getFirstElement is null now, iam in else - " + key);
String elementText = streamAttributeElement.getText();
if (elementText.equals("true") || elementText.equals("false")) {
value = Boolean.parseBoolean(elementText);
} else {
if (NumberUtils.isNumber(elementText)) {
try {
value = numberFormat.parse(elementText);
} catch (ParseException e) {
value = elementText;
}
} else {
value = elementText;
}
}
}
topLevelMap.put(key, value);
}
return topLevelMap;
}
```
topLevelMap should be declared as private global variable. Could someone make ticket on wso2 github to resolve this bug please?

However,here I've written a code snippet:
```
struct A {};
struct B : private A // note: *private* inheritance
{
A* test() {
return dynamic_cast(this);
}
};
int main()
{
B b;
if(b.test()==nullptr)
throw 1;
}
```
In the code snippet above, `A` is just a private base of `B`, which is not taken into account by the c++ primer. However, **this code snippet could be compiled and run without error**. Has the primer made a mistake?<issue_comment>username_1: This is all in all an unfortunate phrasing on the primers part. It bunched the two types of casts one can do into one sentence, and then misspoke as a result.
Casting to a base class, doesn't require a runtime cast operation. It is, [as username_2 says](https://stackoverflow.com/a/49381799/817643), purely a static construct. And like username_2 quoted, it requires an **accessbile** base, not public one. So your code is all good and well.
For a runtime cast (a downcast) the C++ standard places a requirement on the operand and the types involved in a dynamic cast in order for it to succeed. The class must be publicly derived, otherwise the implementation isn't obligated to make a successful cast down the inheritance chain. I mean, it could in theory make the cast successful, but according to the specification [*"the runtime check fails"*](https://timsong-cpp.github.io/cppwp/expr.dynamic.cast#8.3), which doesn't leave much leeway.
But either way there's nothing wrong in your program that would make it fail to compile, nor is there anything there that would cause any sort of runtime error.
---
If we change your code to cast down, and not cast up, here's an [example that doesn't even build](http://coliru.stacked-crooked.com/a/183f7faa7f8eee0f):
```
struct A {};
struct B : private A // note: *private* inheritance
{
A* test(B* p) {
return dynamic_cast(p);
}
friend B\* foo(A\*);
};
B\* foo(A\* a) {
return dynamic\_cast(a);
}
int main()
{
B b;
\*foo(&b);
}
```
`A` is an accessible base of `B` in `foo`, and yet, the cast is ill-formed.
---
The minimal change which will bring the primer back on course is to turn *"a class type that is **publicly** derived from the target type"* into *"a class type that is **accessibly** derived from the target type"*. Since there's nothing of the sort in the [publicly available errata](http://ptgmedia.pearsoncmg.com/images/9780321714114/errata/9780321714114_errata_10-31-12.html), we can guess it's an editorial mistake that is yet to be pointed out.
Upvotes: 4 [selected_answer]<issue_comment>username_2: A derived-to-base `dynamic_cast` is static, not dynamic, and only requires the base to be accessible in the context of the cast (and unambiguous). See [[expr.dynamic.cast]/5](https://timsong-cpp.github.io/cppwp/expr.dynamic.cast#5).
Upvotes: 3 <issue_comment>username_3: The bolded passages are all obviously wrong.
The dynamic cast expression that deals with class types can be logically subdivided in two cases.
* `type` is a class type which is a base class of the *statically determined* type of `e`. In this case dynamic\_cast is more or less synonymous with static\_cast. In particular, `type` must be an accessible and unambiguous (but not necessarily public) base class of the type of `e`.
* `type` is a class type which is not a base class of the *statically determined* type of `e`. In this case, a runtime check takes place. This is further subdivided to the *downcast* and *crosscast* cases. The differences between those are only important in the case of multiple inheritance and/or non-public inheritance. In either of these cases, `type` must be a type of some subobject of the full object of `e`.
The primer never says whether it means static or dynamic type of `e`, but in either case the description is completely wrong. For the cast to succeed,
* `type` does not need to be related to the *static* type of `e` in any way
* `type` must be a base class of the *dynamic* type of `e` or that type itself (but not a proper derived class of it), with further restrictions related to accessibility and non-ambiguity.

I tried most of the solutions provided on other stackoverflow questions but nothing supposed to be working.
please help. Thank you<issue_comment>username_1: The most common reasons to encounter this error is the incompatibility of pip installs and python versions.
Though the error log mentions that your pandas module is not available even after you've installed it, there is a possibility to run into this error is due to the presence of multiple/incompatible versions of python where you've failed to install pandas according to the specific python version.
So first check the python version that you're currently on using
`python -V`
And if you're on **Python 2.** , use
`pip install pandas`
If you're on **Python 3.** use
`pip3 install pandas`.
Then proceed on with your script. This at most should solve your issue.

EXTRACT(year FROM sysdate) as currentyear,

```
substr(numCommande, 1, 6)
```
which gives you `'161013'`; and then convert that string to a date with a suitable format model:
```
select to_date(substr(numCommande, 1, 6), 'RRMMDD') from your_table;
```
Quick demo with static value instead:
```
select to_date(substr('1610131223ZVV40', 1, 6), 'RRMMDD') from dual;
TO_DATE(SU

Unfortunately, it's directly triggering a download whenever a byte-array of information is sent in response.

```

2018/03/20 | 1,307 | 5,148 | <issue_start>username_0: My question is this: what is the best way (or at least an effective way) to write to a file from multiple processes?
**Note:** I am using c++11 and I want this to run on any platform (i.e. pure c++ code only).
I have done some research and here is what I have concluded:
1. In my processes I have multiple threads. This is easily handled within each process using a mutex to serialise access to the file.
2. A c++/c++11 mutex or conditional variable cannot be used to serialise between processes.
3. I need some sort of external semaphore / lock file to act as a "mutex"... but I am not sure how to go about doing this.
I have seen applications use things like creating a ".lock" file when in use. But for multiple rapid access it seems like this may not work (i.e. after one process has decided the file does not exist another could create it and then the first process will also try to create it) because the operation to test and create the file is not atomic.
**Note:** Each process always writes one entire line at a time. I had thought that this might be enough to make the operation "atomic" (in that a whole line would get buffered before the next one), but this does not appear to be the case (unless I have my code wrong) since I (rarely) get a mangled line. Here is a code snippet of how I am doing a write (in case it is relevant):
```
// in c'tor
m_osFile.open("test.txt", std::fstream::out | std::fstream::app)
// in write func (std::string data)
osFile << data<< std::endl;
```
This must be a common-ish issue, but I have not yet found a workable solution to it. Any code snippets would be welcome.<issue_comment>username_1: Usually the operating system provides special functions for locking files that are guaranteed to be atomic (like [lockf](https://stackoverflow.com/questions/2057784/locking-files-in-linux-with-c-c) on Linux or [LockFile(Ex)](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365203(v=vs.85).aspx) on Windows). As by now, the C++ standard library provides no such functionality, so a plattform-independent approach to such facilities is provided by e.g. [Boost.Interprocess](http://www.boost.org/doc/libs/1_66_0/doc/html/boost/interprocess/file_lock.html).
Upvotes: 2 <issue_comment>username_2: Well I can imagine two scenarios. Since you didn't specify in your questions how the processes are spawned, I imagine two situations:
1. Your first process spawns the second process (e.g. using `fork()`).
2. The two processes are generated separately in your environment.
In the first scenario, a simple mutual exclusion access to the wanted resource (mutex) between your processes should work fine. This will prevent to a process to access a resource that is being used by the other process.
The second scenario is a bit more complex, it would require that each process acknowledges the existence of the other. A similar issue has already been discussed [here](https://stackoverflow.com/questions/5210945/atomic-file-creation-on-linux), where it's present an interesting link on [how to avoid race conditions](https://www.dwheeler.com/secure-programs/Secure-Programs-HOWTO/avoid-race.html). I would also consider checking the `O_EXCL` and `O_CREAT` flags for this purpose

The best way is... don't do it!
This really seems a sort of log (appending). I would just let every process write its own file and then merge them when needed. This is the common approach at least, and here it is the rationale.
Any kind of intra-process locking is not going to work. Open files have buffering at OS level, even after being closed on some OSes (windows).
You cannot perform file locking, if you want a portable solution ("I want this to run on any platform"): you are going to meet even possible performance penalties/undefined behavior depending on the filesystem being used (eg: samba, NFS).
Writing concurrently and reliably to a single file is in fact a system-dependent activity, today.
I don't mean that it is not possible - DB engines and other applications do it reliably, but it's a customized operation.
As a good alternative, you can let one process act as a collector (as proposed by <NAME>), all the rest as producers, but this is not going to be a reliable alternative: logs need to get to disk "simply": if a bug can let the logs not to be written, the log purpose is going to be lost.
However you can think to use this approach, decoupling the processes and letting the messages between them to be exchanged reliably and efficiently: if this is the case you can think to use a messaging solution like [RabbitMQ](http://www.rabbitmq.com/).
In this case all the processes publish their "lines" to the message broker, and one more process consumes such messages and write them to file.

2018/03/20 | 886 | 3,330 | <issue_start>username_0: I get the following `warning: parameter 'tupleValue' set but not used [-Wunused-but-set-parameter]`, but the parameter is explicitly used in return statement.
Does it really mean that the return value is ignored somewhere later in the call sequence and compiler is just cool enough to optimize it out on this line?
Here is the code:
```
template
typename removeLastType::type internalRemoveData(intValues, std::tuple tupleValue)
{
return std::forward\_as\_tuple(std::get(tupleValue)...);
}
```
Complete source is here: <https://github.com/copperspice/cs_signal/blob/master/src/cs_internal.h#L316>
Compiled in Windows:
```
-- The C compiler identification is GNU 5.3.0
-- The CXX compiler identification is GNU 5.3.0
```<issue_comment>username_1: Not an answer actually, but you have undefined behavior in your code, as @RinatVeliakhmedov has pointed out. The return value of `internalRemoveData` function is a `std::tuple`, that consist of dangling references, i.e., references to no-longer existing objects.
Consider the following simplified case:
```
struct X {
X() { std::cout << "def ctor\n"; }
~X() { std::cout << "dtor\n"; }
void f() { std::cout << "f\n"; }
};
template
auto f(std::tuple t) {
return std::forward\_as\_tuple(std::get(t)...);
}
int main() {
auto res = f<0>(std::tuple{});
std::cout << "---" << std::endl;
// std::get<0>(res).f(); // would use no-longer existing object
}
```
This program prints out:
```
def ctor
dtor
---
```
After the `f` functions has finished, there does not exist any object of `X` anymore.
---
Note that this problem can be very dangerous, since the program can behave as expected. I tried it in Wandbox with uncommented `std::get<0>(res).f();` statement and the program printed out `f` and did not manifest any error. Undefined behavior includes expected behavior as well.
Upvotes: 2 <issue_comment>username_2: As one of the authors of the original code, I think the behavior here is well defined, but the reason is a bit subtle. Here is my logic. If I have missed something, let's keep the discussion open.
The internalRemoveData method receives a tuple of values, and returns a tuple of values with exactly the same data types, minus the last element. Considering each element in the tuple separately, there are only three possible cases that matter.
1. If the element is a value type, the forward\_as\_tuple function will yield an lvalue reference. This lvalue reference will be assigned to the corresponding element of the return tuple, which is a value type. This will copy from the input to the output, no dangling reference.
2. If the element is an lvalue reference, it must have already been a reference to some valid original object. It will be forwarded as an lvalue reference, which is then bound to the corresponding lvalue reference in the output.
3. If the element is an rvalue reference, it also must have already been a reference to some valid original object. We get the same behavior as the lvalue reference case.
The key to this is seeing that the return type is *not* the same as the type which forward\_as\_tuple returns.
If this question gets closed, look for further discussion on our YouTube channel where the original question was asked: <https://www.youtube.com/watch?v=uK-2jzB41c4>

test.increase();
}
}.start();
while(Thread.activeCount() > 1)Thread.yield();
System.out.println(test.inc);
}
}
```
The first one uses a for and the second one doesn't, and that is the only difference, but the first one gets the result smaller than 2000, the second gets the result equals to 2000, why?<issue_comment>username_1: Consider this operation that you do inside the `increase` method. You first read the existing value, then increment it and write it back. There are several instructions here and that can be interrupted. The reason behind getting a value which is < 2000 is because of the race condition. Using the keyword `volatile` does not guarantee the atomicity. To guarantee atomicity you have to use a lock. Try this out.
```
private final Object lock = new Object();
public void increase() {
synchronized (lock) {
inc++;
}
}
```
Another alternative is to use `AtomicInteger` here. So your code will now look like this.
```
public AtomicInteger inc = new AtomicInteger(0);
public void increase() {
inc.incrementAndGet();
}
```
This also guarantees the atomicity as the name implies.
Upvotes: 2 <issue_comment>username_2: The result `2000` of second test is not guranteed by jls, you can let the thread sleep sometime before increment to make it "break" more easily:
```
public void increase(){
try {
Thread.sleep(20);
} catch (Exception e) {
}
inc++;
}
```
You might get:
```
1997
1999
```
or some other unpredict results.
`volatile` can gurantee the changes to a variable are always visible to other threads, but can not gurantee the actions on this variable is atomic.
Suppose `i = 1`, thread1 and thread2 might read `1` at the same time, and increment it to `2`, then write back, which leads to wrong result.
Upvotes: 1 <issue_comment>username_3: That’s just coincidence. Both variants are equally broken, but the second defines two distinct classes doing the same thing, so before starting the second thread, this additional class has to be loaded, verified and initialized. This overhead gives the first thread a headstart, raising the chance of completing entirely before the second even starts.
So the race condition does not materialize then, but since this execution is not guaranteed, it’s still a broken program containing the possibility of data races. Running the same program in an environment with faster class loading/initialization or an ahead-of-time strategy may exhibit the same behavior as with the first variant.
Note that likewise, it’s not guaranteed that the first variant will experience lost updates. It may still happen that starting the second thread is slow enough to allow the first one to complete without data races. Even if both threads run, the system’s thread scheduling policy may change the likelihood of experiencing lost updates. Also, the entire loop could get optimized to a single increment by `1000`, that would not contradict the requirements for `volatile` variables, even if the current version of the HotSpot JVM doesn’t do that.

2018/03/20 | 700 | 2,435 | <issue_start>username_0: I am currently creating a module to execute a set of codes on hookActionProductCancel. Module is running well and I would like to send out an email after execution.
```
$template_path = $this->local_path . 'mails/';
Mail::Send((int)(Configuration::get('PS_LANG_DEFAULT')),
'xxx', //need to change the template directory to point to custom module
'Subject',

```
I have created the templates and place the files as follow:
1. ../mails/en/xxx.html
2. ../mails/en/xxx.txt
While I understand the default navigation for email templates are above, how do I use templates placed in my custom modules directory?
I have created a directory - ../modules/custommodule/mails/ and placed both files but am not successful in pointing to it.
Any guidance is appreciated. Thank you.<issue_comment>username_1: You can specify template path in [Mail::Send()](https://github.com/PrestaShop/PrestaShop/blob/1.6.1.x/classes/Mail.php#L87) .
You can see that 11th parameter is `$template_path` so you just need to specify that (if you're calling send method from main module class you can use `$this->local_path . 'mails/'`). The `$template_path` parameter must be server file path not URI because the method uses `file_exists()` to check if a template exists. Method will extract from your module path that it is in fact a custom module template.
Now the method will first check if you have mail template in
`themes/shop_theme/modules/mymodule/mails/iso_lang/xxx.html`
then in
`modules/mymodule/mails/iso_lang/xxx.html`
and load the first template it finds. Same goes for txt files.
**Edit:**
How to execute method correctly:
```
Mail::Send(
(int)(Configuration::get('PS_LANG_DEFAULT')),
'xxx', //need to change the template directory to point to custom module
'Subject',
array(
'{aaa}' => $bbb,
'{bbb}' => $ccc,
'{ccc}' => $ddd,
'{ddd}' => $eee
),

null,
$this->local_path . 'mails/' // 11th parameter is template path

Upvotes: 4 [selected_answer]<issue_comment>username_2: yes, I agree with 'username_1' you have to pass 11th parameter correctly and if you face an error with

That's why it will not be calculated using such an independent metrics function (as we are not providing, how ypred was calculated).
However you can calculate the adjusted R2 from R2 with a simple formula given [here](https://en.wikipedia.org/wiki/Coefficient_of_determination#Adjusted_R2)

case msg: String => println("You sent me a String: " + msg)

My questions would be:
1. How can I get rid of the compiler warning
*"non-variable type argument Int in type pattern (Int, scala.collection.immutable.ListMap[Double,Double], scala.collection.immutable.ListMap[Double,Double]) is unchecked since it is eliminated by erasure"*
on the below? I would understand ListMap type erasure, but the compiler seems to complain about the Int..
2. My message (payload) is pretty big (each ListMap has some tens of thousands of raws). The processing consists of displaying the Maps in a plot and computing a sort 'distance' between the two of them.
Is there a preferred alternative to sending this as a message to gain more from parallelism? I'm thinking along the lines of storing the data outside the actor scope..<issue_comment>username_1: 1. Don't send `String`s and tuples with `Int`s and `List`s. Define a proper protocol with case classes you can pattern-match on.
2. Depends on your definition of "ok". You could try to tweak `maximum-frame-size` (see e.g. [here](https://stackoverflow.com/questions/31038115/akka-net-sending-huge-messages-maximum-frame-size)), but then you would soon have to also tweak all kinds of heartbeat-timeouts, because your actors would become increasingly unresponsive, and at some point parts of your system would begin to declare other parts of your system for dead and quarantine each other. With [artery](https://doc.akka.io/docs/akka/2.5/remoting-artery.html?language=scala) this should no longer be a problem.
Upvotes: 2 <issue_comment>username_2: This warning is very common working with pattern matching. The compiler alerts that these types only exist at compile time so it wont differentiate between ListMap[Double,Double] and ListMap[Any, Any]. There are some workarounds using TypeTags. I would give an opportunity to Akka Typed to create a more expressive protocol. An example in how to migrate from classical version to Typed version is detailed here <https://www.bbva.com/en/akka-actors-evolution-type-safe-distributed-computations/>. For processing big datasets like in your case I´d use Spark.

The rownames I want for this dummy data would be `B,C,C,B,E2,E3`. However, I am aware that R does not allow non-unique rownames. I have seven possible rowname classes for my complete dataset, `A,B,C,D,E1,E2,E3`.
I was trying to write a script in R (but failing), that takes a vector of my non-unique rownames, and adds numbers to the elements 1,2,3... so on, depending on the length of that character in the vector.
Thus for this dummy data, the vector I would have is `B-1,C-1,C-2,B-2,E2-1,E3-1`, and my final matrix would be:
```

```<issue_comment>username_1: If you *really* want to do this, then this will work
```
uniqify_names <- function(names_vector) {
names <- unique(names_vector)
count_table <- rep(0, length(names))
names(count_table) <- names # works because R has weird symbol lookup
update_name <- function(name) {
new_name <- paste0(name, ".", count_table[name])
count_table[name] <<- count_table[name] + 1
new_name
}
vapply(names_vector, update_name, FUN.VALUE = "character")
}
```
It works like this:
```
> non_unique_names <- c("A", "B", "A", "A", "B", "C", "A", "B", "C")
> uniqify_names(non_unique_names)
A B A A B C A B C
"A.0" "B.0" "A.1" "A.2" "B.1" "C.0" "A.3" "B.2" "C.1"
```
You can set the row names using `rownames` from this vector.
Upvotes: 2 [selected_answer]<issue_comment>username_2: You can try this.
```r
df <- data.frame(row_name = c('B','C','C','B','E2','E3'))
library(dplyr)
df <- df %>%
group_by(row_name) %>%
mutate(count = sequence(n()),
unique_row_name = paste(row_name, count, sep="-"))
```
`df$unique_row_name` is your candidate!

I will ignore the PCA part (recommendations to use matrix or not to use rownames at all).
To generate wanted vector of names you can use this:
```
foo <- c("A", "B", "C", "C", "B", "E", "E")
paste0(foo, "-", sapply(seq_along(foo), function(x) sum(foo[1:x] == foo[x])))
[1] "A-1" "B-1" "C-1" "C-2" "B-2" "E-1" "E-2"
```

2018/03/20 | 454 | 1,797 | <issue_start>username_0: My daemon keeps querying db on a cronly basis. In every iteration, (a) the deamon makes a DB query (b) receives some documents from db (c) processes those results. I want to emit *the number of documents returned for the query* on Datadog. What is the right metric type?<issue_comment>username_1: [Gauge metric](https://docs.datadoghq.com/developers/metrics/#gauges "Gauge metric") types will do the job here given that your query does not run more than once within 10 seconds. If that is not the case, go for [count metric](https://docs.datadoghq.com/developers/metrics/#count "count metric")
The flush interval in datadog by default is 10 seconds, if you use a **gauge metric** and the metric is reported more than once in a flush interval, datadog agent only sends the last value ignoring the previous ones. For **count metric** in contrast, the agent sums up all the values reported in the flush interval.
More details about flush interval [here](https://help.datadoghq.com/hc/en-us/articles/211545826-Why-histogram-stats-are-all-the-same-inaccurate-Characteristics-of-Datadog-histograms- "here").
Upvotes: 2 <issue_comment>username_2: The best metric type would be a `histogram` metric. This will take multiple values, and pre-aggregate them within a flush window, so you will be able to get things like min/max/sum/avg and various percentiles.
If you run multiple times within a flush window:
* `count` would combine multiple values together, so you would lose the individual numbers, meaning you couldn't easily tell between the process returning a lot of documents, or it returning only a few, but being called a lot
* `gauge`, as mentioned in @username_1's answer, would only keep the latest, making it harder to get thins like the max/min count.

1. split the paragraph into lines and join the first 2 lines:
```
set lines [split $para \n]
set first2 [lrange $lines 0 1]
set wanted [join $first2 \n]
# or
set wanted [join [lrange [split $para \n] 0 1] \n]
```
2. find the position of the 2nd newline and take the characters from the start of the paragraph up to that position
```
set firstnewline [string first \n $para]
set secondnewline [string first \n $para $firstnewline+1]
set wanted [string range $para 0 $secondnewline-1]
```
You can also get the 2nd newline index with
```
set secondnewline [lindex [regexp -all -inline -indices \n $para] 1 0]
```

```
[.orderedAscending, .orderedSame].contains(Calendar.current.compare(date, to: range.from, toGranularity: .day))
```
In my opinion it is a little bit unclear and I looking for better.
### Edit:
According to @Martin\_R answer of course in this example I can do negative equalization:
```
Calendar.current.compare(date1, to: date2, toGranularity: .day) != .orderedDescending
```
`ComparisonResult` used here is only an example. I looking for more general solution answer. For example, what if enum would be have more cases?<issue_comment>username_1: There's a couple of ways to do this:

2018/03/20 | 444 | 1,659 | <issue_start>username_0: I'm trying to configure Gitlab / Git in multi-user and multi-project mode on linux
I have two local repositories
**The problem:**
If I create a repository specifying the login in the url, the local config will contain this credential, and we can only use this one. So we lose the ability to know who push what in the remote
```
git clone https: // login@ url / xxx/ yyy.git
```
**The bad solution:**
Respecify the remote in the global config => we will not be able to work on other repositories
**The ideal solution:**
We should be able to clone a directory without specifying the user in the url:
```
git clone https: // @ url / xxx/ yyy.git
```
Git would ask the user / passwd every time
Except that Gitlab does not allow it; make the following error:
```
git clone https://url/xxx/yyy.git
Initialized empty Git repository in /path/.git/
error: The requested URL returned error: 401 Unauthorized while accessing https://url/xxx/yyy.git/info/refs
fatal: HTTP request failed
```
Thanks in advance for your help<issue_comment>username_1: Please check your current `git` version installed on your local machine.
The command for that would be: `git --version`
Make sure you have git 1.7.10 or later. After that version it should prompt for the username and password.
The Gitlab remote URLs are (without the specific user name):
* HTTPS: `https://domain/owner_name/repository_name.git`

I have seen may examples where arrow keys are used to navigate only between editable cells. There are 50+ columns in my kendo grid in which 20+ cell are editable. I have created a keydown event in databound which works fine only for editable cell. If I move to non editable cell Key press events are not working.
**Current Working Logic:**
Left and Right arrow keys are working only inside Editable cell. Once we reach non editable cell it's not working.
**Desired Working Logic**
When we press arrow key if the cell is editable then it should go in edit mode, if the cell is non editable the focus should stay and when we press left / right arrow key it cursor should move to prev/next cell.
I have created a [telerik dojo](http://dojo.telerik.com/eLaWeCIj).
**UPDATE** This Dojo is working as expected in IE. But in chrome it's not working. Basically `Right arrow key` should work like `TAB` key and `Left Arrow key` should work like `SHIFT+TAB`<issue_comment>username_1: Please check your current `git` version installed on your local machine.

The command for that would be: `git --version`
Make sure you have git 1.7.10 or later. After that version it should prompt for the username and password.
The Gitlab remote URLs are (without the specific user name):
* HTTPS: `https://domain/owner_name/repository_name.git`
* SSH: `git@domain:owner_name/repository_name.git`

2018/03/20 | 1,206 | 3,248 | <issue_start>username_0: I trying to show the weekends between 2 dates in a formatted way.
For an example:
```
$start = strtotime(date('Y-m-d'));
$end = strtotime(2018-06-12);
for ($i = $start; $i <= $end; $i = strtotime("+1 day", $i)) {
//show weekends as
// saturday and sunday - march 24-25, 2018
// saturday - march 31, 2018
// sunday - april 1, 2018
// saturday and sunday - april 7-8, 2018
//.........
}
```
If you can see above i need to group the weekend and if the saturday and sunday falls in 2 different months show them separately.
Can someone please help me how to do this?<issue_comment>username_1: Try this:
```
$start = strtotime(date('Y-m-d'));
$end = strtotime('2018-06-12');
for ($i = $start; $i <= $end; $i = strtotime("+1 day", $i)) {
$date = date('D Y-m-d N', $i);
$n = (int)date('N', $i);
if ($n > 5) {
echo $date . '
---
';
}
}
```
date('N', $i) will give you number of the weekday(1-monday, 7-sunday)
And you check if its greater than 5(6 or 7) (Saturday or Sunday)

The array is built on year, month, week and day.
Then it's just a matter of iterating and echoing.
```
$start = strtotime(date('Y-m-d'));
$end = strtotime("2018-06-12");
for ($i = $start; $i <= $end;) {
If(date("N", $i) == 6){
$arr[date("Y", $i)][date("F", $i)][date("W", $i)][date("l", $i)] = date("d", $i);
$i+= 86400;
$arr[date("Y", $i)][date("F", $i)][date("W", $i)][date("l", $i)] = date("d", $i);
$i+= 86400*6;
}Else If(date("N", $i) == 7){
$arr[date("Y", $i)][date("F", $i)][date("W", $i)][date("l", $i)] = date("d", $i);
$i+= 86400*6;
}Else{
$i+= 86400;
}
}
Foreach($arr as $year => $years){
Foreach($years as $month => $months){
Foreach($months as $week){
Echo implode(" and ",array_keys($week)) . " - " . $month . " " . Implode("-", $week) . ", ". $year . "\n";
}
}
}
```
<https://3v4l.org/nHe0d>
Edit: forgot to output month.
Edit 2: changed the initial loop to not loop all days. Should make it slightly faster.
Edit 3: found a bug in the code. Corrected.

**Ex:**
```
import datetime
s = (3090, 'Backup-Local.2018-02-04_23.05.00_57', 'Backup-Local',

2018/03/20 | 580 | 2,192 | <issue_start>username_0: I currently creating a program using Java + Selenium WebDriver, currently having a difficulty of looping technique in Java.
Below is my code:
Assume,
>
> rt = {Capacity Utilization,Overlay Report}
>
>
> fq = {15 Minute,Hourly,Daily}
>
>
>
Code::
```
for( String rt : rep_type ) {
new Select(driver.findElement(By.name("reporttype"))).selectByVisibleText(rt);
for( String fq : freq ){
try {
Thread.sleep(2000);
new Select(driver.findElement(By.name("frequency"))).selectByVisibleText(fq);
Thread.sleep(3000);
} catch (Exception e){
e.printStackTrace();
}
Thread.sleep(1500);
try {
WebElement selectElement = driver.findElement(By.id("firstPeriod"));
Select select = new Select(selectElement);
List opts = select.getOptions();
------
-----
----
--
-
```
The problem is, when 'rt' equal to "Overlay Report", there are no element for this report to match the String in 'fq' array. Hence, it will proceed to the next code within the same loop.
How I can jump into the initial loop again which is,
```
for( String rt : rep_type ) {
```
so it will not proceed to the next code when there are no condition met with 'fq' array.<issue_comment>username_1: You're looking for either the `break` or `continue` keywords. When called from within a loop they will either break out of the loop or skip to the end of the current iteration.
So, your potential solution will look like this:
```
for( String rt : rep_type ) {
if ("Overlay Report".equals(rt)) {
continue;
}
// rest of code
```
Upvotes: 1 <issue_comment>username_2: You can label your loop and use it just like this:
```
myLoopForInitialCycle:
for(Smth smth : smths) {
...
for(Smth smth2: smths2) {
if (smth.equals(smth2) {
continue myLoopForInitialCycle;
}
}
}
```
This smells like structural style, and some measures have to be executed to avoid it, but I think this is just what you are asking for.

As you already know that **Android Oreo** introduced the new design for **media controls**, rather than selecting a singular color for the **notification based on the app's color**, media playback notifications can instead **draw colors out of the album artwork**. Android then uses those colors to make a notification that blends the artwork into the notification while making the notification itself pop in your **notification shade**.
May I know how we can do this ?<issue_comment>username_1: <https://developer.android.com/reference/android/app/Notification.Builder.html>
To fill with solid colour:
```
.setColorized(boolean colorize)
```
Set whether this notification should be colorized.
-A media template lets the user control media currently playing from an app.
The collapsed view displays up to three actions, and the large icon can show a related image, such as an album cover.
The expanded view displays up to five actions with a larger image, or six actions if no image is displayed. Colors from provided images automatically color the notification's background and other elements.
(<https://material.io/guidelines/patterns/notifications.html#notifications-templates>)
-Media notifications will automatically get colorized based on the album art.
The Palette API takes the album art, extracts some colors, and applies it to the media player notification.
Upvotes: 0 <issue_comment>username_2: This is MediaStyle for Notification. You need to set MediaStyle and media session tokon and thats it. For example:
```
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID);
//building some actions...
builder.setSmallIcon(R.mipmap.ic_launcher)
.setStyle(new android.support.v4.media.app.NotificationCompat.MediaStyle()
.setShowActionsInCompactView(0, 1, 2)
.setShowCancelButton(true)
.setMediaSession(mediaSessionCompat.getSessionToken()))
.setCategory(NotificationCompat.CATEGORY_TRANSPORT)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setShowWhen(false)
.setContentTitle("Title Name")
.setContentText("Content text")
.setSmallIcon(R.drawable.pause)
.setWhen(0)
.setAutoCancel(true)
.setLargeIcon(icon);
```

Every thread writes (produces) in the queue something like:
```
INSERT INTO CHAT_COMMENTS (chat_comment_id, comment) values (3,'This is a comment';
```
The above string generated as
```
sprintf(insert_statement, "INSERT INTO CHAT_COMMENTS (chat_comment_id, comment) values (%d,'%s')",e->id,e->comment);
```
A scheduler runs every a while and executes all of these insert statements in a MySQL database. Now, the problem is that comments might have some MySQL special characters as shown below:
```
cout << comment; // produces "this_% LIKE 'a comment """\m/'DROP TABLE USERS"
INSERT INTO CHAT_COMMENTS (chat_comment_id, comment) values (3,'this_% LIKE 'a comment """\m/'DROP TABLE USERS');
```
Is there a way to handle these case?
I know that one can use prepared statements, but I am looking for something different as PreparedStatements are not thread safe and also because I want to execute the queries above in batches.<issue_comment>username_1: You're probably looking for the [`mysql_real_escape_string()`](https://dev.mysql.com/doc/refman/5.7/en/mysql-real-escape-string.html) function.

----------------------------------------
Use prepared statements. If you need to ensure that the prepared statement (or connection) is only used on one thread at a time, associate it with a `std::mutex` (or similar) that you lock while it is being used.
```
class threaded_statement;
class threaded_connection
{
std::unique_ptr conn;
std::mutex mut;
public:
threaded\_statement prepareStatement(const char \* stmt)
{
std::lock\_guard guard(mut);
return { conn->prepareStatement(stmt) };
}
};
class threaded\_statement
{
std::unique\_ptr stmt;
std::mutex mut;
public:
threaded\_statement(sql::PreparedStatement \* stmt) : stmt(stmt) {}
void setInt(int pos, int value)
{
std::lock\_guard guard(mut);
stmt->setInt(pos, value);
}
void setString(int pos, std::string value)
{
std::lock\_guard guard(mut);
stmt->setString(pos, value);
}
// etc ...
void execute()
{
std::lock\_guard guard(mut);
stmt->execute();
}
}

2018/03/20 | 824 | 2,523 | <issue_start>username_0: I like how easy it is to write some variables to console output in C++ using `qDebug` from Qt:
```
int a = b = c = d = e = f = g = 1;
qDebug() << a << b << c << d << e << f << g;
```
Result:
```
1 1 1 1 1 1 1
```
In comparison, using `std::cout` would require me to add the spacing and newline manually to get the same result:
```
std::cout << a << " " << b << " " << c << " " << d << " " << e << " " << f << " " << g << "\n";
```
While I often use Qt, I sometimes work on projects where adding the Qt framework just to get access to qDebug would be overkill. And although it is not hard to write a new class that behaves similar to `qDebug`, I am wondering if any established alternative to `std::cout` with similar behavior to `qDebug` already exists?
**Edit:** What I am looking for is ideally an *established* library (or snippet, but I prefer something existing over rolling my own) that I can always use as my go-to solution when I need something like this. It could be header-only, or a large logging library that is much used and well-tested, or a simple, small snippet. The point is that it should be small and/or standard enough that other collaborators would be okay with including it in a project just for debugging/logging purposes.
**Edit 2**: To clarify: It would be great to have a solution that both inserts spaces between the variables and newlines for each statement:
```
myDebug << 1 << 2 << 3;
myDebug << 4 << 5 << 6;
```
Should return:
```
1 2 3
4 5 6
```<issue_comment>username_1: ```

We can render the Dropdown using the cell render method, but that way it doesn't cover the whole table cell because of cell padding. Thus the user has to precisely click the displayed text, instead of the whole cell.<issue_comment>username_1: For the context menu you can use `Dropdown` or `Popover` components with some css customization, but the problem is the popup menu doesn't appear next to mouse pointer, it appears relatively to a wrapped element. You can check it **[here](https://codesandbox.io/s/n90579l9pm)** what I ment above.

Upvotes: 3 <issue_comment>username_4: `IRequestCultureFeature` provides the first matched language, which is supported by your application. Declaration of supported languages is defined in Configure() of your Startup class (see [example](https://github.com/aspnet/Localization/blob/master/samples/LocalizationSample/Startup.cs)). If you still need all accepted languages as a simple `string[]` like the older `Request.UserLanguages` property, then use the `HeaderDictionaryTypeExtensions.GetTypedHeaders()` extension defined in the `Microsoft.AspNetCore.Http` namespace:
```
// In your action method.
var languages = Request.GetTypedHeaders()
.AcceptLanguage
?.OrderByDescending(x => x.Quality ?? 1) // Quality defines priority from 0 to 1, where 1 is the highest.
.Select(x => x.Value.ToString())
.ToArray() ?? Array.Empty();
```
The array `languages` contains the list of accepted languages according to the priority parameter `q`. The language with the highest priority comes first. To get the default language take the first element of the array `languages`.
As an extension method:
```
using System.Collections.Generic;
using System.Linq;
using Microsoft.AspNetCore.Http;
public static class HttpRequestExtensions
{
public static string[] GetUserLanguages(this HttpRequest request)
{
return request.GetTypedHeaders()
.AcceptLanguage
?.OrderByDescending(x => x.Quality ?? 1)
.Select(x => x.Value.ToString())
.ToArray() ?? Array.Empty();
}

2018/03/20 | 3,178 | 8,364 | <issue_start>username_0: There is a big javascript library (~ 40 000 lines of code) and an application which uses less than **50%** of the library's code.
There is a test which utilizes all the needed functionality from the library and can produce coverage report.
How to remove programmatically every unused line of code relying on the test?
**Note**: coverage report contains indices of lines which were executed but it is not accurate: closing braces are ignored, lines with method names are marked as executed even if the method body was not etc.<issue_comment>username_1: This approach will not work I fear. Not that easy and not with the data you have available at least.
1. The coverage report for your *test which utilizes all the needed functionality* is using which coverage metric? Does it excercise all values, conditions and possible combinations thereof? If not, you may miss out on usage of some part of the code.
2. If your coverage report is not accurate you cannot rely on it for removal actions. Although braces
Given a sufficiently good test suite you can use the code coverage reports for hints however. Remove code that is reported as unused, re-run your tests and check whether they still pass. Repeat until nore more code snippets can be removed.

Removing a dead code block

```
function hello(name) {
alert('Hello, ' + name);
}
function hi(name) {
alert('Hi, ' + name);
}
hello('New user 1');
hello('New user 2');
```
Compiles to:
```
alert("Hello, New user 1");
alert("Hello, New user 2");
```
completely stripping away the `hi` function and inlining `hello`.

Moving to a more complicated case
---------------------------------
As the code gets more complicated, it finds new ways to optimize. For example:
```
let greeted = 0;
function hello(name) {
greeted += 1;
alert('Hello, ' + name);
}
function hi(name) {
greeted += 1;
alert('Hi, ' + name);
}
hello('New user ' + greeted);
hello('New user ' + greeted);
```
Becomes:
```
var a = 0;
function b() {
var c = "New user " + a;
a += 1;
alert("Hello, " + c);
}
b();
b();
```

1. **Dead code elimination (DCE)** :
compiler optimisation- It excludes which is not needed in the program.
2. **Tree Shaking**
It works in reverse direction, includes only what is actually needed in the program.

1. Tree shaking
2. Ugliy and Minification tools such as uglifyjs, Terser
3. Google closure compiler (best results)
However, in order to find the unused assets, to remove manually, you can use [deadfile](https://m-izadmehr.github.io/deadfile/#/) library:
<https://m-izadmehr.github.io/deadfile/>
It can simply find unused files, in any JS project.

Yes, after this we have only the js code used, but unfortunately it is not valid. You can manually fix the errors and then everything will be ok.

sum(amount) as amount_m

2018/03/20 | 1,221 | 3,178 | <issue_start>username_0: I'm trying to transform this unicode value:

I feel like I've tried everything:
```
decoded_str = string_value.decode('utf-8')
```
or
```
string_value = str(string_value)
decoded_str = string_value.encode('latin1').decode('utf-8')
```
or
```
string_value = string_value.decode('latin-1')
```
for this one the result is:
>
> d\xc3\xa9cid\xc3\xa9
>
>
>
I have the same result if I do:
```
string_value = string_value.encode('utf-8')
```
I've read from:
[How do I convert 'blah \xe9 blah' to 'blah é blah'](https://stackoverflow.com/questions/27197507/how-do-i-convert-blah-xe9-blah-to-blah-%C3%A9-blah)
also from:
[Why does Python print unicode characters when the default encoding is ASCII?](https://stackoverflow.com/questions/2596714/why-does-python-print-unicode-characters-when-the-default-encoding-is-ascii)
and:
[How do I convert a unicode to a string at the Python level?](https://stackoverflow.com/questions/2783079/how-do-i-convert-a-unicode-to-a-string-at-the-python-level)
EDIT:
My problem is I need to use the data, I mean if I have :
>
> string\_value = u'mai 2017 \u2013 Aujourd\u2019hui'
>
>
>
which is :
>
> mai 2017 – Aujourd’hui
>
>
>
I want to do:
```
string_list = string_value.split('-')
```
But the result is:
```
[u'mai 2017 \u2013 Aujourd\u2019hui']
```
And I would:
```
['mai 2017', 'Aujourd’hui']
```
NEW EDIT:
I understand that I'm going to the wrong direction, thanks to your answer.
\xe9 is the right representation of 'é' and it's not a problem.
My real issue is why does json.loads() transform 'mai 2017 – Aujourd’hui' to 'mai 2017 \u2013 Aujourd\u2019hui' ?<issue_comment>username_1: I am not sure what you're asking: `\xe9` is a representation of the code point 233 (`e9` in hexadecimal), [which simply is the letter "é"](http://www.codetable.net/decimal/233):
```
>>> u'é' == u'\xe9'
True
```
Your confusion might stem from the fact that the `repr` of a Python string is (in Python 2) in ASCII, so non-ASCII characters are escaped. The Python console displays a value using `repr` if you do not `print` it explicitly:
```
>>> print(repr(u'é'))
u'\xe9'
>>> print(repr(u'\xe9'))
u'\xe9'
```
However, when you print the value, then it that conversion doesn't happen and everything works as expected:
```
>>> print(u'é')
é
>>> print(u'\xe9')
é
```
Also note that in Python 3, `repr` returns Unicode:
```
Python 3.5.2 (default, Nov 23 2017, 16:37:01)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> print(repr(u'\xe9'))
'é'
```
**Update after the question was edited:**
As pointed out in the comments, `\u2013` is not the same character as `-` (just as `a` and `b` are separate characters). So you'll need to split on `\u2013` instead of splitting on `-`.

I ran into a problem in my application. I want to implement a post search by the post title, post text, and its tags, I have a search form and I want ALL posts that contain this word in the title or text or tags to be displayed, but now it works differently, for example, I have 2 posts:
one of them contains the word "hello" in the header, and the other has the tag "hello",
I want both of these posts to be displayed, but now only the one that has the tag is displayed, and the second with the word "hello" in the header is ignored, I don't know why. I know that the problem with my `Post.search` method.
Please help me, thank in advance!
**Here is my code:**
**Post.rb:**
```
class Post < ApplicationRecord
mount_uploader :image, ImageUploader
validates :body, presence: true, length: { maximum: 500}
validates :title, presence: true, length: { maximum: 50}
validates :adress, length: { maximum: 50}
belongs_to :user
has_many :taggings
has_many :tags, through: :taggings
has_many :comments, dependent: :destroy
has_many :favorites, dependent: :destroy
def self.search(keywords)
if keywords
joins(:tags).where("lower (title) ILIKE :value OR
lower (body) ILIKE :value OR
lower (tags.name) ILIKE :value",
value: "%#{keywords.downcase}%")
else
all.order("created_at DESC")
end
end
end
```
**Post Controller index action:**
```
def index
@posts = Post.search(params[:keywords]).uniq
end
```<issue_comment>username_1: Try to the following
**Option One**
```
Post.includes(:tags).where("lower (posts.title) ILIKE :value OR
lower (posts.body) ILIKE :value OR
lower (tags.name) LIKE :value",
value: "%#{params[:keywords].downcase}%" ).references(:tags)
```
Or something like this direct to your controller index action
**Option Two**
```

if params[:keywords].present?
@posts = Post.includes(:tags).where("lower (posts.title) ILIKE :value OR
lower (posts.body) ILIKE :value OR
lower (tags.name) LIKE :value",
value: "%#{params[:keywords].downcase}%" ).references(:tags)
else
@posts = Post.all.order(created_at: :DESC)
end
end
```

/home/user/Desktop/IS/proj_1/sch/text 4 2018-03-14 07:41:01

And I need to delete that one particular line from the file somehow. I've searched many posts and tried using various quotations and ways of expansions, but nothing did the trick. If I type it in directly, it deletes the line without problem, but I'm having a hard time doing it from a variable. This is what I came up with but it still doesn't work.

2018/03/20 | 470 | 1,739 | <issue_start>username_0: Consider the following code:
```
auditlog.getMessages()
.stream()
.filter(m -> messageId.equals(m.getMessageid()))
.findFirst()
.orElseThrow(NoMessageFoundException::new)
```
`NoMessageFoundException` is a custom unchecked exception, extending from `RuntimeException`. When `findFirst()` returns an empty optional I expect a `NoMessageFoundException` to be thrown, however, the code just carries on.
Is it impossible to do this with unchecked exceptions?
I could change `NoMessageFoundException` to a checked exception, but then I would have to write a `try/catch` block or some sort of wrapper to catch the exception as explained [here](http://www.baeldung.com/java-lambda-exceptions) but I wish to not do that.
Any ideas?<issue_comment>username_1: There is no limitation on the type of Exception that can be thrown.
```
public T orElseThrow(Supplier extends X exceptionSupplier) throws X {
if (value != null) {
return value;
} else {
throw exceptionSupplier.get();
}
}
```
If the code "carries on", it means that a message is found.
Upvotes: 3 [selected_answer]<issue_comment>username_2: if the exception is not getting throw is because there is at least one element remaining after the filter action...
see this example:
```
public class ASFasf {
public static void main(String[] args) {
List l = Arrays.asList(1, 2, 3, 4, 5);
Integer iR = l.stream().filter(x -> x > 100).findFirst().orElseThrow(NoMessageFoundException::new);
System.out.println(iR);
}
}
class NoMessageFoundException extends RuntimeException {
public NoMessageFoundException() {
super("Opala!!");
}
}
```
iR will never get printed, and a `NoMessageFoundException` is thrown....

You have to use Paramiko API to list the files, like [`SFTPClient.listdir`](https://docs.paramiko.org/en/latest/api/sftp.html#paramiko.sftp_client.SFTPClient.listdir):
```
import fnmatch

sftp = client.open_sftp()

You can also use a regular expression for the matching, if it suits your needs better. See [Using wildcard in remote path using Paramiko's SFTPClient](https://stackoverflow.com/q/51866185/850848).

2018/03/20 | 755 | 2,651 | <issue_start>username_0: I have this code
```
textureAtlas = TextureAtlas("atlas.atlas")
val box = textureAtlas.findRegion("box")
```
I want to create a texture with "box". Is it possible? box.texture return the original texture, not the regioned. Oh and I don't want to use Sprite and SpriteBatch. I need this in 3D, not 2D.
Thanks<issue_comment>username_1: You can do this:
```
Texture boxTexture = new TextureRegion(textureAtlas.findRegion("box")).getTexture();
```
Upvotes: -1 <issue_comment>username_2: TextureAtlas actually not separating pieces. When you get region from atlas its just saying that this is the area you gonna use (u,v,u2,v2) and this is original reference to whole texture.
This is why batch.draw(Texture) and batch.draw(TextureRegion) are not same in use.
However taking part of picture as texture is possible.
* You can use pixmap to do it.
First generate pixmap from atlas texture. Then create new empty pixmap in size of "box" area you want. Then assign pixel arrays and generate texture from your new pixmap.
It may be quite expensive due to your Textureatlas size.
* You can use framebuffer.
Create FBbuilder and build new frame buffer.Draw texture region to this buffer and get texture from it.
Problem here is the sizes of texture will be same as viewport/screen sizes.I guess you can create new camera to change it to sizes you want.
```
GLFrameBuffer.FrameBufferBuilder frameBufferBuilder = new GLFrameBuffer.FrameBufferBuilder(widthofBox, heightofBox);
frameBufferBuilder.addColorTextureAttachment(GL30.GL_RGBA8, GL30.GL_RGBA, GL30.GL_UNSIGNED_BYTE);
frameBuffer = frameBufferBuilder.build();
OrthographicCamera c = new OrthographicCamera(widthofBox, heightofBox);
c.up.set(0, 1, 0);
c.direction.set(0, 0, -1);
c.position.set(widthofBox / 2, heightofBox / 2, 0f);
c.update();
batch.setProjectionMatrix(c.combined);
frameBuffer.begin();
batch.begin();
batch.draw(boxregion...)
batch.end();
frameBuffer.end();
Texture texturefbo = frameBuffer.getColorBufferTexture();
```
Texturefbo will be y flipped. You can fix this with texture draw method by setting scaleY to -1 or You can scale scaleY to -1 while drawing on framebuffer or can change camera like this
```
up.set(0, -1, 0);
direction.set(0, 0, 1);
```
to flip to camera on y axis.
Last thing came to my mind is mipmapping this texture.Its also not so hard.
```
texturefbo.bind();
Gdx.gl.glGenerateMipmap(GL20.GL_TEXTURE_2D);
texturefbo.setFilter(Texture.TextureFilter.MipMapLinearLinear,
Texture.TextureFilter.MipMapLinearLinear);
```

Meanwhile I got stuck when pass separate "where" sequelize statement into one.
Okay, this is my current code :
```
var periodsParam = {};

tipe: 1,
variantid: (!ctx.params.id ? ctx.params.id : variants.id)
};
if (ctx.query.country) {

}
console.log(periodsParam);
```
From code above, its always return `{ country: 'SG' }` , but I want to return `{ delete: 'F', tipe: 1, variantid: 1, country: 'SG' }`
How can I resolve that ?
Anyhelp will appreciate, thankyouu.<issue_comment>username_1: The problem was that you were always re initializing it. You should set it as a property of the existing object.
Update from
```
periodsParam = {
country: ctx.query.country
};
```
to
```
periodsParam.country = ctx.query.country;
```
Upvotes: 2 <issue_comment>username_2: You can also just assign the Object like this:
`periodsParam = Object.assign({}, periodsParam, { country: ctx.query.country });`
Upvotes: 1 <issue_comment>username_3: The problem is, you're using `=` sign with `periodsParam` 3 times and you end up with `periodsParam` returning only `country`, because of this lines:
```
if (ctx.query.country) {
periodsParam = {
country: ctx.query.country
};
}
```
Instead of assigning new object to `periodsParam`, use dot notation to add another key-value pair, like this:
```
if (ctx.query && ctx.query.country) { //before accesing .country check if ctx.query is truthy
periodsParam.country = ctx.query.country;
}
```
As [@Paul](https://stackoverflow.com/users/3756843/paul-rey) suggested, condition should be `ctx.query && ctx.query.country` - it will prevent TypeError if `ctx.query` is `undefined`.

2018/03/20 | 865 | 3,612 | <issue_start>username_0: Yes, I read the other questions on the same topic, but they do not cover my issue.
We run two environments; DEV and Prod. The two were synched last week, meaning they ought to contain the same data, run the same SSIS packages, and source the same source data.
However, today we had a package on PROD go through its' usual steps (3 tables being truncated, and then loaded from OLEDB source to OLEDB destination, one after the other). The package finished without throwing an error, and the first 2 tables contain data, whereas the last one does not.
On DEV, everything looks fine.
I went through the package history, and it actually shows it wrote 0 rows:
[](https://i.stack.imgur.com/dAced.png)
Yesterday, however, it worked as intended:
[](https://i.stack.imgur.com/XKLMS.png)
When I manually ran the package, it wrote data. When I click "Preview", it displays data. When I manually run the source query, it consistently returns data, the same amount of rows, every time. The SSIS catalog has not been updated (no changes were deployed to PROD between yesterday and today).
The source query does not use table variables, but it does use CTEs. I have seen suggestions to add `SET NOCOUNT ON`, and willing to accept this could be an explanation. However, those answers seem to indicate the package never writes any data, whereas this package has worked successfully before, and works successfully on DEV.
Does anyone have any explanation as to how I can explain to my customer that I have no clue as to why 1 package suddenly chose not to write any data, and how I can ensure this won't happen again, to either this package or any of the other packages?<issue_comment>username_1: This can be tricky. Try the following:
1. Under `Integration Service Catalogs -> SSISDB -> project -> (right click)Reports -> Standard Reports -> All executions`. Check here if at any point, ETL job lost contact with warehouse.
2.If you have logging enabled, try to see at what task\_name your package started returning 0:
```
select
data_stats_id,
execution_id,
package_name,
task_name,
source_component_name,
destination_component_name,
rows_sent
from
ssisdb.catalog.execution_data_statistics
```
3. How are you handling transactions and checkpoints? This is important if you want to know root cause of this issue. It may happen that due to loss of connectivity had forced to rollback any write in warehouse.
Upvotes: 1 <issue_comment>username_2: As it turns out, the issue was caused by an oversight.
Because we run DEV and PROD on the same server (we know, and have recommended the customer to at the very least consider using different instances)), we use variables in which we point at the proper environment (set in the environment variables).
The query feeding this particular package was updated, and apparently rather than using the variable to switch databases, it was hard-coded (likely as result of testing, and then forgetting to update the variable). The load for DEV and PROD run at the same time, and we suspect that while PROD was ready, DEV was still processing the source tables, and thus 0 rows were returned.
We only found this out today because the load again ran fine right until this morning. I was too late to catch it using Profiler, but because it was only this package, I checked, and spotted the hardcoded reference to \_DEV.
Thanks everyone for chiming in.

* def uuid = function(){ return java.util.UUID.randomUUID() + '' }
```
You can now call this feature like this:
```
* call read('common.feature')
```
And now all the functions in that feature are available for use:
```
* def time = now()
* def id = uuid()
```

2018/03/20 | 377 | 1,434 | <issue_start>username_0: I've got a PowerShell-Script to create a VM from an Image in Azure and in this Script I deposited a `.json` (Parameter for VM, etc.). But if I want to create more than one VM the Names of the VM, Vnet, etc. cannot be the same for every execution (have to be in the same Resource Group).
So my Question: How can I insert Variables in the .json File to change the Name of the VM, etc. for every execution? Perhaps I have to rethink?
[](https://i.stack.imgur.com/G7aTp.png)<issue_comment>username_1: A very basic approach could be something like this:
```
# Grab the file contents
$contents = Get-Content -Path $templateFile
# Update some tokens in the file contents
$contents = $contents.replace("original value", "new value")
# Push the updated contents to a new file
Set-Content -Path $updatedFile -Value $contents
```

That way, you can generate the values in your powershell script without having to output them to json file first.
For more details, have a look at the [cmdlet specs](https://learn.microsoft.com/en-us/powershell/module/azurerm.resources/new-azurermresourcegroupdeployment?view=azurermps-5.5.0)

2018/03/20 | 395 | 1,555 | <issue_start>username_0: I am having an issue while binding the Image path to img src in angular 2.
I am saving the image in localdisk and saving the path in the database and retrieving the image path and binding to the img source tag but it is not binding. I tried to bind the local disk url directly to the image tag then i am getting error "**Not Allowed to load local resources.**", If i bind the local path value to **SafeUrl variable** then the error is **unsafe:E:\Main Projects\img\20182201521541566536.jpg:1**
can any one please give me some solution.
thanks<issue_comment>username_1: You cannot read files from your harddrive as image source. You need to provide the images in your project, so they are available on localhost.
Upvotes: 0 <issue_comment>username_2: Below works for me
Step 1 ) import { DomSanitizer } from '@angular/platform-browser';
Step 2 )Then in constructor add the dependency
public \_DomSanitizationService: DomSanitizer
Step 3 )Now bind property as
this.ImagePath = this.\_DomSanitizationService.bypassSecurityTrustUrl(this.FilePath);
Upvotes: -1 <issue_comment>username_2: I have one more solution for it and its working for me. We can host our images on IIS and then we can provide the http path to SRC of IMG tag.
When you deploy your code to any live server then you have to pass the http path of images as per the live server settings.
Browsers consider those URLs as unsafe which dont have http attached to them.
If anyone still finding any issue then please let me know, I'll share my code here.

2018/03/20 | 706 | 2,526 | <issue_start>username_0: I am trying to have expandable list items in a table with constant header. For this I am using `Table` and `ExpansionPanel` component from React material ui 1.0.0-beta.34. However, table is not alligning well. All the body data comes under one header `TableCell`.
Here is my code.
Table component:
```
import React, { Component } from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import Table, { TableBody, TableCell, TableHead, TableRow } from 'material-ui/Table';
import Paper from 'material-ui/Paper';
import { styles } from './styles';
import ExpandableTableRow from 'client/components/expandable-table-row';
class GenericTable extends Component {
render() {
const { classes, items, headItems } = this.props;
return (
{headItems.map((n, i) => {
return {n}
}) }
{
!items.length &&
There is no data to display
}
{items.map((item, i) => {
return (
);
})}
);
}
}
GenericTable.propTypes = {
items: PropTypes.array.isRequired,
headItems: PropTypes.array.isRequired,
};
export default withStyles(styles)(GenericTable);
```
ExpandableTableRow component:
```
import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import ExpansionPanel, {
ExpansionPanelSummary,
ExpansionPanelDetails,
} from 'material-ui/ExpansionPanel';
import Typography from 'material-ui/Typography';
import { styles } from './styles';
import { TableRow, TableCell } from 'material-ui/Table';
class ExpandableTableRow extends React.Component {
render() {
const { classes, item } = this.props;
return (
{item.a}
{item.b}
{item.c}
{item.d}
{item.e}
{item.f}
Expansion panel expanded
);
}
}
ExpandableTableRow.propTypes = {
};
export default withStyles(styles)(ExpandableTableRow);
```
I am trying to make this work. Any help is appreciated.<issue_comment>username_1: Im also looking into the same problem. Apparently, material UI has an issue thread regarding expandable table rows. this [link](https://github.com/mui-org/material-ui/issues/4476) might help you.
Edit: React now has docs for Collapsible Table here. <https://material-ui.com/components/tables/#collapsible-table>
Upvotes: 2 <issue_comment>username_2: This is how I solved this problem earlier. I wrapped a `Collapse` transition inside a `TableCell` and set it's `hidden` and `in` prop. Example:
```
{
}
```

For dat of week in alphabets, you use EEEE or EEE similar to MMM & yyyy for month year.

dateFormatter.setLocalizedDateFormatFromTemplate("EEE MMM d yyyy")
print(dateFormatter.string(from: Date())) // "Tue, Mar 20, 2018" for en-US locale

```
func timeStamp()->String {

Upvotes: 2 <issue_comment>username_5: The best way to change your date is follow this method.
```
func ChangeDateFormat(date:String,FromFormat: String, ToFormat: String) -> String {
let dateFormatter1 = DateFormatter()
dateFormatter1.dateFormat = FromFormat
let myDate = dateFormatter1.date(from: date)
dateFormatter1.dateFormat = ToFormat
if(myDate != nil){
let Date = dateFormatter1.string(from: myDate!)
return Date
}
else{
return ""
}
}
```
and then you can use this method like
```
String(ChangeDateFormat(date: StartDate, FromFormat: "yyyy-MM-dd hh:mm:ss a", ToFormat: "MMM d, yyyy"))
```
You can pass your date format in which format do you want in your case it should be
```
String(ChangeDateFormat(date: StartDate, FromFormat: "Pass your date format", ToFormat: "EEE MMM d, yyyy"))
```
Upvotes: 0 <issue_comment>username_6: Rather than needing to spell out a date format. I would simplify it further to:
```
dateFormatter.dateStyle = .full
```
Or if you just want the day:
```
dateFormatter.dateFormat = "EEEE"

2018/03/20 | 1,044 | 4,017 | <issue_start>username_0: How can I return 1 or 0 using COUNT between two dates?
```
CREATE PROCEDURE [dbo].[CheckCharterDate]
@DateCheck date,
@DateCheck2 date,
@charterID int
AS
SELECT Count(StartDate)
FROM Booking
WHERE StartDate >= @DateCheck
AND EndDate <= @DateCheck2
AND CharterID = @charterID
RETURN 0
```
This stored procedure only returns 1 or 0 whenever the user selects exactly the two dates that are in the database but if they select a date in between, it returns a 0 and it says that it's available.<issue_comment>username_1: I think you are looking for overlapping date ranges.
The way to test if two ranges overlap is to make sure one starts before the second ends, while the second starts before the first end. You can see a visualization of this in the [overlap](/questions/tagged/overlap "show questions tagged 'overlap'") tag [info](https://stackoverflow.com/tags/overlap/info).
```
CREATE PROCEDURE [dbo].[CheckCharterDate]
@DateCheck date,
@DateCheck2 date,
@charterID int
AS
SELECT Count(StartDate)
FROM Booking
WHERE StartDate <= @DateCheck2
AND EndDate >= @DateCheck
AND CharterID = @charterID
```
Also, as username_3 noted in his answer, you should use `exists` instead of `count`.

```
CREATE PROCEDURE [dbo].[CheckCharterDate]

BEGIN
SELECT CASE WHEN Count(StartDate)=0 THEN 0
ELSE 1 END AS Count_StartDate
FROM Booking
WHERE StartDate <= @DateCheck2
AND EndDate >= @DateCheck
AND CharterID = @charterID
END;
```
**Why I Changed the order of inequalities?**
Since for overlapping date ranges what is the basic condition:
If you have to check `start_date` and `end_date` is overlapping between `@DateCheck` and `@DateCheck2` `( @DateCheck < @DateCheck2)` then
Check
if `start_date` is less than `@DateCheck2` or not And also `end_date` is greater than `@DateCheck` or not.
So that's why there should be a change in the inequalities.
Upvotes: 3 [selected_answer]<issue_comment>username_3: Don't use `COUNT()` for this. From a performance perspective, it is suboptimal.
Instead, use `EXISTS`:
```
CREATE PROCEDURE [dbo].[CheckCharterDate] (
@DateCheck date,
@DateCheck2 date,
@charterID int
) AS
BEGIN
SELECT (CASE WHEN EXISTS (SELECT 1
FROM Booking b
WHERE b.StartDate <= @DateCheck2 AND
b.EndDate >= @DateCheck2 AND
b.CharterID = @charterID
THEN 1 ELSE 0
END) as overlap_flag
END;
```
I don't recommend that you return a value from a stored procedure -- unless that value is a status. Instead, just write a user defined function:
```
CREATE FUNCTION dbo.udf_CheckCharterDate (
@DateCheck date,
@DateCheck2 date,
@charterID int
) RETURNS INT
BEGIN
DECLARE @flag int;
SELECT @flat = (CASE WHEN EXISTS (SELECT 1
FROM Booking b
WHERE b.StartDate <= @DateCheck2 AND
b.EndDate >= @DateCheck2 AND
b.CharterID = @charterID
THEN 1 ELSE 0
END) as overlap_flag;
RETURN @flag;
END;
```
The function can simply be used as any other function. For instance:
```
WHERE dbo.udf_CheckCharterDate( . . . ) = 1

This is how I save the files:
```
private void uploadFile() {
progressBar.setVisibility(View.VISIBLE);
StorageReference sRef = mStorageReference.child(Constants.STORAGE_PATH_COURSES + System.currentTimeMillis() + ".pdf");
sRef.putFile(filepath)

textViewStatus.setText("File Uploaded Successfully");
Course upload = new Course(editTextFilename.getText().toString(), taskSnapshot.getDownloadUrl().toString());
mDatabaseReference.child(mDatabaseReference.push().getKey()).setValue(upload);
}
})
.addOnFailureListener(new OnFailureListener() {

double progress = (100.0 \* taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
textViewStatus.setText((int) progress + "% Uploading...");
}
});
}
```
I searched for the possibilities and tried a few but I can not make them work.
I tried to use this, but it displays nothing.

```
pdfView=(PDFView) findViewById(R.id.pdfView);
Bundle bundle = getIntent().getExtras();
if (bundle != null) {
url = getIntent().getStringExtra("url");
}
uri=Uri.parse(url);
pdfView.fromUri(uri).load();
```
If I load the pdf from the assets folder, it works well.
I've also tried the webview:
```
WebView webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://drive.google.com/viewerng/viewer?embedded=true&url=" + url)
```
I'm really new to Android and I'm sure that I do something wrong...I would be really grateful if someone could help me. Thanks!<issue_comment>username_1: `AndroidPdfViewer` library supports loading PDF file from local storage not from remote url.Since your are trying to load remote link it wont show anything.You need to download your pdf file in app cache and load it from that path
`WebView` will work fine in this situation because its loading a remote url in a browser
You can refer the following Issue [HERE](https://github.com/barteksc/AndroidPdfViewer/issues/423)

2018/03/20 | 373 | 1,339 | <issue_start>username_0: In my `swift 4` project I have `iOS 9.0` as `deployement target` and I'm using the `safe area layout guide`.
In the `storyboard`, I always give 0 as value between my main `view` top space and the `safe area` top. When I run the application in `iOS 9` or `iOS 10` I'm having a white space at the top.
How can I remove this white space without disabling the `safe area layout guide`?<issue_comment>username_1: I guess you are testing on iPhone X? You can change safe area insets such way:
```
var newSafeArea = UIEdgeInsets()
newSafeArea.top -= 20
self.additionalSafeAreaInsets = newSafeArea
```

Upvotes: 2 <issue_comment>username_3: I can't explain why, but in the storyboard views don't calculate the navigationbar height and therefor you will have an (often 44px) white space. You can remove this by either as username_2 said, by turning of `Adjust Scroll View insets` or you can do it programmatically by setting `edgesForExtendedLayout = []` in your `viewDidLoad()`

2018/03/20 | 602 | 2,121 | <issue_start>username_0: Ive just installed redis and sidekiq on my app,
I Have a job to update a field on the users table when called upon,
And a job that sends an email once a week to all users.
Now if i boot up sidekiq with `bundle exec sidekiq` The job to update the users field fires off and completes but the email job stays in the enqueued section.
But if i boot it up with `bundle exec sidekiq -q workers -q mailers` Which i got from the Sidekiq github page only the mail jobs get completed and the others stay in the enqueued section.
Is there a command to be able to run both? Ive only started to learn about sidekiq and redis yesterday so sorry if this a stupid question,
I have the `activejob.que_adaptar` set to `sidekiq` in application.rb.
This is how i have my sidekiq worker for the User job set up:
```
class DeactivateUser
include Sidekiq::Worker
def perform
User.active.update_all(active: false)
end
end
```
Thanks.<issue_comment>username_1: Create `config/sidekiq.yml` with list of your queues and run `sidekiq -C config/sidekiq.yml`.
```
#config/sidekiq.yml
---
:concurrency: 5
:queues:
- default
- mailers
- orders
```
Upvotes: 2 <issue_comment>username_2: As username_1 configured, follow the same approach to have multiple queues processed by single sidekiq process. In addition, you have to mention the queue name in the worker file. So that the sidekiq process will get the jobs from redis of that queue. For ex: ( `sidekiq_options queue: :mailers` )
```
class WORKER_NAME
include Sidekiq::Worker
sidekiq_options queue: :
def perform
... # your work
end
end
```
If you want to start process only listening to one queue mailers and having concurrency 10, please start like this.
`bundle exec sidekiq -c 10 -C config/myapp_sidekiq.yml -q mailers -q queue1 -q queue2`
This will listen to total of 3 queues named `mailers`, `queue1`, `queue2`. This is how you will have to start the sidekiq. For more documentation, please [refer to this](https://github.com/mperham/sidekiq/wiki/Advanced-Options).

2018/03/20 | 369 | 1,294 | <issue_start>username_0: I came across a weird issue on google chrome which seems to be new because I'm pretty sure it worked before (on older version).
```css
.container {
width: 400px;
height: 266px;
overflow: hidden;
position: relative;
border: 2px solid red;
margin-bottom: 30px;
}
iframe {
position: absolute;
width: 480px;
height: 350px;
top: 50%;
left: 50%;
transform: translateX(-50%) translateY(-50%);
z-index: -1;
overflow:hidden;
}
```
```html
```
You see that the first container contains a youtube iframe and is bigger than the container, but with overflow:hidden it shouldn't be visible and 'cutted' on the sites. But google chrome is not able to do this anymore (all other browsers works fine). The second container just contains a normal page and there the hidden overflow works well, so I guess it's somehow related to video embeds (vimeo embeds = the same issue). It seems like a bug from their site.
Do you have any workaround for this?<issue_comment>username_1: The Chrome overflow problem is resolved. Google fixed it
Upvotes: 1 <issue_comment>username_2: I updated today my Google Chrome to version 66.0.3359.117 and the bug was resolved.

2018/03/20 | 735 | 2,306 | <issue_start>username_0: First I will explain my situation:
I added react-native-multiple-select-list package to my react-native project by running: 'yarn add react-native-multiple-select-list':
```
"dependencies": {
"react-native-multiple-select-list": "^1.0.4"
}
```
The package [email protected] has a dependency on react-native-vector-icons package:
```
"dependencies": {
"react-native-vector-icons": "^3.0.0"
},
```
The problem is that [email protected] has unmet dependency with my react@16
I found on github that the on the new version (1.0.5) the issue was fixed and the version of react-native-vector-icons changed to 4.5 which is met with react@16
But this version (1.0.5) is not published yet to npm.
So my questions are:
* Is there a way you use the last github version?
* I tried to change manually the version of "react-native-vector-icons" to 4.5 and than run `yarn install` from inside the package. It works, but each time I run `yarn add` (no matter which package) it gets changed
back the version to 3. Is there way to keep it on 4.5?
Thanks

Now:
1. Initially, I selected a package(Woo Subscription)
2. Then I added all the details.
3. But did not submit it.
4. Came back to the site, so to buy again I need to select a package. So I selected the package and filled in details and went to the payment package.
5. Now in my cart both the packages are present (i.e the one I selected without buying first time and the recent one)
6. How can this be fixed so the latest selected one is in the cart and earlier one deleted as soon as latest one selected.
I tried this [Woocommerce Delete all products from cart and add current product to cart](https://stackoverflow.com/questions/21181911/woocommerce-delete-all-products-from-cart-and-add-current-product-to-cart) but did not help.<issue_comment>username_1: Updated *(with 2 different alternatives)*:
You should try the following:
```
add_filter( 'woocommerce_add_to_cart_validation', 'remove_cart_item_before_add_to_cart', 20, 3 );
function remove_cart_item_before_add_to_cart( $passed, $product_id, $quantity ) {
if( ! WC()->cart->is_empty() )
WC()->cart->empty_cart();
return $passed;
}
```
*Code goes in functions.php file of your active child theme (or theme)*. **Tested and works** with both ajax-add-to-cart and normal add-to-cart…
---
Or you can use this different one that will keep in cart the last added item:
```
// Keep only last cart item
add_action( 'woocommerce_before_calculate_totals', 'keep_only_last_cart_item', 30, 1 );
function keep_only_last_cart_item( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
$cart_items = $cart->get_cart();
if( count( $cart_items ) > 1 ){
$cart_item_keys = array_keys( $cart_items );
$cart->remove_cart_item( reset($cart_item_keys) );
}
}
```

```
INSERT INTO #TMP call SPName;
```
to store the result in temp table but it says **feature not supported**. Is there anyway to store the result of stored procedure in temp table. I don't want to alter the definition of already build SP but want to store the result in temp table to join with another set of statement to get my final result.<issue_comment>username_1: Have you tried to use an output table type as one of your stored procedure parameter? And then use that out parameter in your stored procedure to return the result?
This is the typical approach used in many example in the documentation.
```
DROP TYPE TT_MYTYPE;
CREATE TYPE TT_MYTYPE AS TABLE(A VARCHAR (100), B INT);
DROP PROCEDURE MYPROC;
CREATE PROCEDURE MYPROC (OUT OUTPUT_TABLE TT_MYTYPE )
LANGUAGE SQLSCRIPT SQL SECURITY INVOKER
AS
BEGIN
OUTPUT_TABLE = SELECT 'Test' as A, 3 as B FROM DUMMY;
END;
-- output table is created dynamically and in the overview you can get the table name
CALL MYPROC( ? ) with overview;
-- pass an output parameter table to receive the result
DROP TABLE MYOUTPUT;
CREATE TABLE MYOUTPUT LIKE TT_MYTYPE;
CALL MYPROC( MYOUTPUT ) with overview;
SELECT * FROM MYOUTPUT;
```
Hope this helps.
Upvotes: 2 <issue_comment>username_2: You can use the **WITH RESULT VIEW** extension of the procedure definition.
For example, if I use the @Abdel's code
```
CREATE PROCEDURE MYPROC (OUT OUTPUT_TABLE TT_MYTYPE )
LANGUAGE SQLSCRIPT
READS SQL DATA
WITH RESULT VIEW myView
AS
BEGIN
OUTPUT_TABLE = SELECT 'Test' as A, 3 as B FROM DUMMY ;
END;
```
Then you can simply execute a SELECT statement on myView as follows
```
SELECT * FROM myView ;
```
For more details on how you can use [With Result View to select data from HANA procedure](http://www.kodyaz.com/sap-abap/select-from-procedure-on-hana-database-using-sqlscript.aspx), you can refer to given tutorial.
If your procedure accepts input parameters, the view created by "with result view" can be queried just like a parametric view

2018/03/20 | 1,521 | 4,544 | <issue_start>username_0: I have a pandas dataframe:
[](https://i.stack.imgur.com/HNXlY.png)
It has around 3m rows. There are 3 kinds of `age_units`: Y, D, W for years, Days & Weeks. Any individual over 1 year old has an age unit of Y and my first grouping I want is <2y old so all I have to test for in Age Units is Y...
I want to create a new column `AgeRange` and populate with the following ranges:
* <2
* 2 - 18
* 18 - 35
* 35 - 65
* 65+
so I wrote a function
```py
def agerange(values):
for i in values:
if complete.Age_units == 'Y':
if complete.Age > 1 AND < 18 return '2-18'
elif complete.Age > 17 AND < 35 return '18-35'
elif complete.Age > 34 AND < 65 return '35-65'
elif complete.Age > 64 return '65+'
else return '< 2'
```
I thought if I passed in the dataframe as a whole, I would get back what I needed and then could create the column I wanted something like this:
```py
agedetails['age_range'] = ageRange(agedetails)
```
BUT when I try to run the first code to create the function I get:
```none
File "", line 4
if complete.Age > 1 AND complete.Age < 18 return '2-18'
^
SyntaxError: invalid syntax
```
Clearly it is not accepting the AND - but I thought I heard in class I could use AND like this? I must be mistaken but then what would be the right way to do this?
So after getting that error, I'm not even sure the method of passing in a dataframe will throw an error either. I am guessing probably yes. In which case - how would I make that work as well?
I am looking to learn the best method, but part of the best method for me is keeping it simple even if that means doing things in a couple of steps...<issue_comment>username_1: With Pandas, you should avoid row-wise operations, as these usually involve an inefficient Python-level loop. Here are a couple of alternatives.
### Pandas: [`pd.cut`](https://pandas.pydata.org/pandas-docs/stable/generated/pandas.cut.html)
As @JonClements suggests, you can use `pd.cut` for this, the benefit here being that your new column becomes a [Categorical](https://pandas.pydata.org/pandas-docs/stable/categorical.html).
You only need to define your boundaries (including `np.inf`) and category names, then apply `pd.cut` to the desired numeric column.
```
bins = [0, 2, 18, 35, 65, np.inf]
names = ['<2', '2-18', '18-35', '35-65', '65+']
df['AgeRange'] = pd.cut(df['Age'], bins, labels=names)
print(df.dtypes)
# Age int64
# Age_units object
# AgeRange category
# dtype: object
```
### NumPy: [`np.digitize`](https://docs.scipy.org/doc/numpy-1.14.0/reference/generated/numpy.digitize.html)
`np.digitize` provides another clean solution. The idea is to define your boundaries and names, create a dictionary, then apply `np.digitize` to your Age column. Finally, use your dictionary to map your category names.
Note that for boundary cases the lower bound is used for mapping to a bin.
```
import pandas as pd, numpy as np
df = pd.DataFrame({'Age': [99, 53, 71, 84, 84],
'Age_units': ['Y', 'Y', 'Y', 'Y', 'Y']})
bins = [0, 2, 18, 35, 65]
names = ['<2', '2-18', '18-35', '35-65', '65+']
d = dict(enumerate(names, 1))
df['AgeRange'] = np.vectorize(d.get)(np.digitize(df['Age'], bins))
```
### Result
```
Age Age_units AgeRange
0 99 Y 65+
1 53 Y 35-65
2 71 Y 65+
3 84 Y 65+
4 84 Y 65+
```
Upvotes: 7 [selected_answer]<issue_comment>username_2: This task can also be done using numpy methods. In particular, `numpy.select` can be used here to convert the numeric data into categorical data. It is very similar to the if-else ladder in the OP; only the conditions are in one list and the return values are in another list.
```py
import numpy as np
conds = [df['Age']<2, df['Age'].between(2, 18), df['Age'].between(19, 35), df['Age'].between(36, 65)]
names = ['<2', '2-18', '18-35', '35-65', '65+']
df['AgeRange'] = np.select(conds, names[:-1], names[-1])
```
Another method is `numpy.searchsorted`. In fact, under the hood, `pd.cut` implements this method as well. The basic idea is to find where each age would be inserted in `bins` to preserve order (which is essentially what binning is) and select the corresponding label from `names`.
```py
bins = [0, 2, 18, 35, 65, np.inf]
names = np.array(['<2', '2-18', '18-35', '35-65', '65+'])
df['AgeRange'] = names[np.searchsorted(bins, df['Age'])-1]
```

This is most likely due to not setting up your mail service properly. Make sure you have all the correct `.env` variables and details in the `config/mail.php` set

I've built a bespoke *share* include for a client site. It works fine but I'm sure one of you clever lot can help me to make it less bulky.
I have three share URLs:
`$share_url_facebook`, `$share_url_twitter` and `$share_url_linkedin`.
Each URL is different in its structure and is fairly complex.
I then have the following code:
```
echo '[';
echo '';
echo '](' . $share_url_facebook . ' "Share this on facebook")';
echo '[';
echo '';
echo '](' . $share_url_twitter . ' "Share this on twitter")';
echo '[';
echo '';
echo '](' . $share_url_linkedin . ' "Share this on LinkedIn")';
```
Is there a way for me to create some sort of loop to prevent the repetition?

Based on the accepted solution by @JasonK here is my final(simplified) tested code:
```
$share = [

foreach ($share as $key => $details) {
echo '[';
echo '';
echo '](' . $details['url'] . ' "Share this on ' . $details['title'] . '")';
}
```<issue_comment>username_1: You can use array to store "config". Key is a name of service, value is url or variable with url.
After that, you can iterate on this array using foreach.
In foreach you can use echo or other function to output string, or asigne string to variable. I used sprintf to format all string without contacenation and to assigned it to variable <http://php.net/manual/en/function.sprintf.php>
```
$services [
'facebook' => $share_url_facebook,
'twitter' => $share_url_twitter
]
$output = '';
foreach ($services as $serviceName => $url) {
$output += sprintf(
'',
$url,
ucfirst($serviceName),
$serviceName
);
}
```

This way you can remain your old variables. This is especially useful, if they come from a file you didnt write yourself and therefore cant/dont want to change
```
$social = [ 'facebook', 'twitter', 'linkedin' ];
foreach ($social as $site) {
print '[';
print '';
print '](' . ${'share_url_' . $site} . ' "Share this on ' . $site . '")';
}

Eg.
```
$now = new DateTime();
$itemDate->diff($now)->format("%r%a")
```
But almost always these types of posts don't really have an explanation about what format parameters are about. I'm okay with regular Date format parameters but (as in this case) not sure about eg. %r.<issue_comment>username_1: r - Sign "-" when the difference is negative, empty when positive
a - Total number of days as a result of a DateTime::diff() or (unknown) otherwise.
As an example,
```
php
$now = new DateTime();
$d = new DateTime('2019-01-01T15:03:01.012345Z');
$x = $d-diff($now)->format("%r%a");
echo $x;
?>
```
Output: string(4) "-287"

You don't have DateTime's anymore, you have interval, and intervals are formatted different as DateTime objects. Format is explained here: <http://php.net/manual/en/dateinterval.format.php>

2018/03/20 | 912 | 3,095 | <issue_start>username_0: I have a template txt file. This template needs to be written as 10 new files where I can then make amendments to each file based on certain conditions (not relevant to the question).
I read my template file as follows:
```
with open('template.txt', 'r') as template_file:
file_lines = template_file.readlines()
file_lines = [line.rstrip('\n') for line in file_lines]
for i in range(10):
new_file = open('output_%s' % i, 'w')
new_file.write(file_lines)
new_file.close()
```
It won't work as I cannot write a list to each file, it must be a string, but I don't know how to get every element from that list to be written in the same file 10 times...Each time I try it a different way I end up getting each line on different files, rather than all lines in all files.
Something wrong in my logic I cannot work out.
Another way I can do it as :
```
template_file = open('template.txt', 'r')
template_lines = template_file.read()
for i in range(10):
new_files = open('output_%s' % i, 'w')
new_files.write(template_lines)
```
But I want to be able amendment particular lines which makes it more convenient to write into each new file line by line (via readlines())<issue_comment>username_1: Try indenting the `new_file.close()` so it's saved after every for loop

Something like:
```
with open('template.txt', 'r') as template_file:
file_lines = template_file.readlines()
file_lines = [line.rstrip('\n') for line in file_lines]
for i in range(10):
with open('output_%s' % i, 'w') as new_file:
new_file.write_lines(file_lines)
```
Also not sure you need the `rstrip('\n')` as `readlines()` already should be removing newlines.
Upvotes: 2 <issue_comment>username_3: I don't fully understand what you want to achieve. Anyways, here is a code snippet of how you can write the same line to every one of the 10 files:

file_lines = template_file.readlines()
file_lines = [line.rstrip('\n') for line in file_lines]
for line in file_lines:
for i in range(10):
new_file = open('output_%s' % i, 'a') # appending content
new_file.write(line)
new_file.close()
```
or even this, if you prefer:
```

file_lines = template_file.readlines()

```
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP\_HOST} ^www\.
RewriteCond http%1://%{HTTP\_HOST} ^(https?://)(www\.)?(.+)$
RewriteRule ^ https://%3%{REQUEST\_URI} [R=301,L]
# BEGIN WordPress
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST\_FILENAME} !-f
RewriteCond %{REQUEST\_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
```
This redirects to `https://` and removes `www.` from `http://` urls. However, it doesn't remove the subdomain if the `https://` is already there, so e.g. `http://www.example.com` is changed to `https://example.com`, but `https://www.example.com` remains unchanged.
What am I doing wrong?<issue_comment>username_1: You could exclude main domain to match all sub domain + remove wwww + force https :
```
RewriteCond %{HTTP_HOST} !^(www\.)?maindomain\.com$
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\.
RewriteCond %{HTTP_HOST} ^(www\.)?(.+)$
RewriteRule ^ https://%2%{REQUEST_URI} [L,R=301]

```

RewriteCond %{HTTPS} off

Additionally, if you don't override the command when you start your image, use `CMD` ([documentation](https://docs.docker.com/engine/reference/builder/#cmd)) instead of `ENTRYPOINT` (and also try to use more "normal" quotes instead of `”`):
```
CMD ["java", "-jar", "/app.jar"]

This was my `Dockerfile`:
FROM openjdk:8-jre
```
VOLUME /tmp
WORKDIR /app
COPY payment-collection.jks .
RUN cat /app/payment.jks
RUN keytool -list -v -keystore /app/payment.jks -storepass my-name.
RUN mkdir cert
COPY payment.jks /app/cert
COPY /target/payment-1.0.1-SNAPSHOT.jar /app
ENTRYPOINT [\"java\",\"-jar\",\"/app/${prod_jar_name}.jar\"]
EXPOSE 443
```
But when I deploy the docker app, I get the error:
>
> /bin/sh: 1: ["java","-jar","/app/payment-1.0.1-SNAPSHOT.jar"]: not found
>

>
**Here's how I fixed it**:
I simply changed from this:
```
ENTRYPOINT [\"java\",\"-jar\",\"/app/payment-1.0.1-SNAPSHOT.jar\"]
```
To this:
```
ENTRYPOINT ["java", "-jar", "/app/payment-1.0.1-SNAPSHOT.jar"]
```
So my new `Dockerfile` looked like this after then:
```
FROM openjdk:8-jre
VOLUME /tmp
WORKDIR /app
COPY payment-collection.jks .
RUN cat /app/payment.jks
RUN keytool -list -v -keystore /app/payment.jks -storepass my-name.

2018/03/20 | 2,392 | 9,560 | <issue_start>username_0: Are there some special things that must be considered to avoid memory leaks in [Mule Applications](https://www.mulesoft.com/de/resources/esb/what-mule-esb)?
How can we avoid memory leaks in Mule Applications?
For example; Do we actually have to remove flow variables? What must be done done explicitly by the developers of the Mule Applications and what is done (automatically) by the [Mule Runtime](https://www.mulesoft.com/de/platform/mule) and the [JVM GC](https://stackoverflow.com/questions/3798424/what-is-the-garbage-collector-in-java)?<issue_comment>username_1: **General Recommendations**
* Session Variables
For applications with many endpoints, prefer fewer and smaller session variables over many or
large ones.The session scope is serialized and deserialized every time a message crosses
an endpoint, even a VM endpoint. So if an application has a lot of endpoints, it will involve many
serializations/deserializations. Using fewer and smaller session variables helps minimize this
overhead.
* Payload format
When it comes to performance, not all formats are equal. Some payload formats allow faster
access to data than others. Bean payloads tend to be the fastest for Mule applications. So if it is
a viable option given other considerations, create payloads in Java objects.
* Data Extraction
Mule Expression Language (MEL) can be used to extract data from messages.8 In terms of
performance, allowing MEL to extract data can be preferable to using a scripting language.
Scripting languages are dynamically typed. Some are even interpreted at runtime. Those factors
can generate overhead that may degrade performance.
* Flow References
Flow references are a pleasantly direct way to enable flow communication within an application.
Flow references are preferred for communications between flows than VM endpoints. Flow
references inject messages into the target flow without intermediate steps. Although the
VM connector is an in-memory protocol. It emulates transport semantics that serialize and
deserialize parts of messages. The phenomenon is especially notable in the Session scope. As
such, flow references are superior to VM endpoints for the purpose of inter-flow communication
because the former avoid unnecessary overhead generated by serialization and deserialization.
**JVM and GC flags can be set for Mule in wrapper.conf .**
It is easy to get passionate about a particular Java Virtual Machine (JVM) or garbage collection
(GC) method. JRockit versus HotSpot, parallel mark-and-sweep (MS) versus G1.
* MuleSoft uses HotSpot, the standard Oracle JVM. HotSpot is
well-supported and easy to customize for a variety of purposes.
MuleSoft’s performance testing emphasizes throughput, and thus
parallel GC. HotSpot is also easy to optimize for response time. The
tips in the following sections show how to calibrate HotSpot for
throughput or response time.
* Designate the initial and maximum heap sizes to be the same value.
This can be done by setting MaxMetaspaceSize=MetaspaceSize and
MaxNewSize=NewSize . Doing so can avoid the need for the JVM to
dynamically allocate additional memory during runtime. The flags are
set in wrapper.conf .
e.g.
wrapper.java.additional.16=-XX:NewSize=1365m
wrapper.java.additional.17=-XX:MaxNewSize=1365m
wrapper.java.additional.18=-XX:MetaspaceSize=256m
wrapper.java.additional.19=-XX:MaxMetaspaceSize=256m
wrapper.java.additional.20=-Xms=2048m
wrapper.java.additional.21=-Xmx=2048m
* There are at least two reasons why such dynamic reallocation can
hinder performance. First, the JVM performs a major GC for each heap
resize. A full GC stops all threads for a period of time. That holds
even when using concurrent mark-and-sweep (CMS). World-stopping
should always be minimized, other things being equal. This is
especially crucial for applications prioritizing low response times.
Dynamic heap resizing creates a second worry when memory is tight.
Suppose the JVM increases its heap size during runtime and the system
does not have enough free memory pages readily available. As a
result, some pages for a kernel-chosen process might be swapped out
to disk. The circumstance would incur slowdown due to increased disk
IO.
**Garbage Collection**
HotSpot is equipped with three canonical garbage collection (GC) mechanisms. These are
serial, parallel, and concurrent mark-and-sweep (CMS).18 Garbage First (G1) has recently been
added to the list.19 The JVM uses parallel GC by default on machines with 2 or more physical
processors and 2 or more GB of physical memory.
Parallel GC is the default garbage collection algorithm in HotSpot JVM. When triggered, it uses
multiple threads to scan, move and collect the unreachable objects in the heap.
CMS GC (Concurrent-Mark-Sweep)
Concurrent mark-and-sweep (CMS) GC is designed to reduce application pauses by running
most of the cleaning phases concurrently with the application threads, hence it offers more
control over the stall time which affects the application response time.
Here is an example demonstrating how to set the JVM to use CMS, plus other options. Set the
following in Mule’s wrapper.conf file. Section 6, “Sample Configuration Files” gives additional
context in which the flags are set.
```
wrapper.java.additional.22=-XX:+UseConcMarkSweepGC
wrapper.java.additional.23=-XX:CMSInitiatingOccupancyFraction=65
wrapper.java.additional.24=-XX:UseCMSInitiatingOccupancyOnly
```
The flag -XX:CMSInitiatingOccupancyFraction designates a percentage of the total heap
usage. When that percentage is reached, the JVM will trigger a CMS GC. A value of 40 to
70 typically suffices for applications running on Mule. If the value is too low, it could result in
excessive, premature collections. It is usually recommend to start at a relatively higher value for
-XX:CMSInitiatingOccupancyFraction and decrease it as needed to optimize for the fewest CMS
events for the best performance.
Specify -XX:+UseCMSInitiatingOccupancyOnly when designating -XX:
+CMSInitiatingOccupancyFraction . Otherwise, the JVM attempts to dynamically adjust the value
for -XX:+CMSInitiatingOccupancyFraction. A changing value is undesirable in most production
scenarios. That is because dynamic adjustment is based on statistical analysis that may not
reliably account for load spikes.
GC logging is a good idea for performance tests. The GC log, once enabled, provides
extremely valuable information about the activities in the heap and how they affect the runtime
performance. GC logging tends to have little overhead for disk IO.
Here is an example of how to enable various aspects of GC logging. Add these configurations to
Mule’s wrapper.conf file.
```
wrapper.java.additional.4=-XX:+PrintGCApplicationStoppedTime
wrapper.java.additional.5=-XX:+PrintGCDetails
wrapper.java.additional.6=-XX:+PrintGCDateStamps
wrapper.java.additional.7=-XX:+PrintTenuringDistribution
wrapper.java.additional.8=-XX:ErrorFile=%MULE_HOME%/logs/err.log
wrapper.java.additional.9=-Xloggc:%MULE_HOME%/logs/gc.log
wrapper.java.additional.10=-XX:+HeapDumpOnOutOfMemoryError
```
Upvotes: 2 <issue_comment>username_2: A good way to get to the memory leak suspects would be to take a heap dump (of all the nodes) right after you start seeing a decline in memory reclaim post-major GC. There are multiple tools available that help analyze the memory leaks.
There is [a great blog post](https://dzone.com/articles/enduring-black-fridays-with-mulesoft-apis) in the topic. This has summarized some memory-leak related issues like the following findings for example:
**Finding**: *Pooled memory manager generally grabs 10% of JVM heap and lives with it without releasing.*
Fix: Switch the Grizzly Memory Manager implementation HeapMemoryManager. Note that HeapMemoryManager is the default implementation and is recommended by Grizzly for performance; albeit, Mule treats PoolMemoryManager implementation as the default.
Wrapper.conf changes:
```
wrapper.java.additional.=-Dorg.glassfish.grizzly.DEFAULT\_MEMORY\_MANAGER=org.glassfish.grizzly.memory.HeapMemoryManager
```
**Finding**: *Async logging was being used widely and associated Log4J was observed to be holding a lot of JVM memory.* The default setting of 256\*1024 slots was apparently too high. Since this RingBuffer does not grow or shrink, a high fixed size with each slot allocated as a separate object (RingBufferLogEvent), each holding a log event, could occupy a considerable amount of memory.
**Fix**: *Reduce the Log4J RingBuffer size to 128 in wrapper.conf or log4j2.xml*
```
wrapper.java.additional.=-DAsyncLoggerConfig.RingBufferSize=128
```
Or, in log4j2.xml:
```
```
Memory leak due to default HazelCast implementation used for aggregator components (splitter-Aggregator pattern).
**Finding**: Heap analysis pointed memory being held up by default HazelCast objectstore implementation used in splitter-aggregator components used in specific flows. It appeared as if the store was not getting expired appropriately.
**Fix**: Custom Object store implementation (subclass of PartitionedInMemoryObjectStore) was written and TTL (TimeToLive) for entries explicitly defined.
```
@Override
public void expire(int entryTTL, int maxEntries, String partitionName) throws ObjectStoreException
{
super.expire(entryTTL, maxEntries, partitionName);
if (getPrivatePartitionSize(partitionName) == 0) {
disposePartition(partitionName);
}
}
```

Since the library is big, parsing it is slow and **I have to wait for a long time until IntelliSense becomes relevant** again.
Is there a way to speed up this parsing, perhaps, by excluding the library from IntelliSense?
This question is NOT a duplicate of [Visual Studio 2017 is too slow during building and debugging](https://stackoverflow.com/questions/42877071/visual-studio-2017-is-too-slow-during-building-and-debugging) because it deals specifically with speeding up IntelliSense, which is not touched by the other question, nor it's answers.<issue_comment>username_1: You can increase Rescan Solution interval in the VS settings.

---
Then I start playing with **Automatic Precompiled Header Cache Quota** (*Tools > Options > Text Editor > C/C++ > Advanced*). In first step I've increased it from default 50Gb to 75gb - guess what: it became slower and slower. Once cache directory (*[solution directory].vs*) reached the limit - IntelliSense became completely useless.
If you think: really, how 50gb-75gb of precompiled code could lead to faster IntelliSense? Such amount of data has to be indexed, queried... maintained.
**Setting limit to 10Gb made my day**. IntelliSense became responsive as it should be.

I have to point out that issue is not limited to VS2017, but also occurs in VS2019. This issue actually made me trying VS2019. While VS2019 is really much better with C++ than VS2017, it has the same problem with project cache. Also, it is important to say that this is not only VS C++ issue, I had same/similar problem with project cache [.vs] back in my C# years. It is just more drastic with C++ projects due language specifics.

I've changed access settings of the google spreadsheet to allow anyone with it's link to view and edit it. This error is arising only when I'm trying to write into the spreadsheet, I'm able to read a spreadsheet using other functions.<issue_comment>username_1: No one knows what domains you white-listed so no one can reproduce your code. And your spreadsheet doesn't have the `Class Data` sheet and you tried wrongly to write at `A1:C1` not `A1:A4`.
So I added a sheet and changed `values` and tried with the [API explorer](https://developers.google.com/sheets/api/reference/rest/v4/spreadsheets.values/update). The result was `200 OK`. Maybe you can try `'RAW'` instead of `"RAW"` or/and `values: values` instead of `resource: body`.

Clear and delete show up, but the upward and downward arrows don't show up. Here is the stackblitz: <https://stackblitz.com/edit/angular-hntkry?file=app%2Fapp.component.html>

as well as @Mateusz Juruś is right, there should be `_` instead of `space`.

2018/03/20 | 872 | 2,889 | <issue_start>username_0: I have two different contents, I want to show the contents as marquee in single line and the contents should display one after another with some delay time duration.
```
Label 1 content here
Label 2 content here
```<issue_comment>username_1: Instead of using and tags (which you shouldn't use in this context), please try using JavaScript this way:
```js
$(function () {
$(".slider .slide").hide();
$(".slider .slide:first").fadeIn().delay(10000).fadeOut(function () {
$(this).next().fadeIn();
});
setInterval(function () {
$(".slider .slide:first").fadeIn().delay(10000).fadeOut(function () {
$(this).next().fadeIn();
});
}, 20000);
});
```
```html
Label 1 content here
Label 2 content here
```
The above is a bare minimal demonstration of what you might like. Let me know if you need more improvement on this. ☺
Upvotes: 1 <issue_comment>username_2: You may use this way, without marquee, basing on jquery queue and adding a css class to your elements:
```js
$(function () {
var current_button = 0;
$('div.slider .slide:first')
.show(100)
.addClass('active');
setInterval(function() {
if(current_button===$('.slide').length) {
$('div.slider .slide:first')
.show(100)
.addClass('active');
current_button=0;
} else {
$('div.slider .slide')
.hide(100)
.removeClass('active');
$('div.slider .slide:eq(' + current_button + ')')
.show(100)
.addClass('active');
current_button++;
}
},3500)
});
```
```css
.slide {
float: left;
transform: translateX(400%);
transition: all 7s;
}
.active {
transform: translateX(-350%);
}
```
```html
Label 1 content here
Label 2 content here
```

2018/03/20 | 577 | 2,202 | <issue_start>username_0: The query I'm trying to do is query that taking from OrderDetails all the items that accounts bought sum them for one row and show for me how much bought from any product, what i am tring to do it is to show the itemname and the item Image
not only the id and sum
this is the query that i did:
```
string strSql = "SELECT Sum(OrderDetails.ItemStock),OrderDetails.ItemID,Items.ItemName,Items.ItemImage FROM OrderDetails,Items WHERE OrderDetails.ItemID = Items.ItemID GROUP BY OrderDetails.ItemID ORDER BY SUM(OrderDetails.ItemStock) DESC";
```
the error that i got from this query :
"The query does not include the specified phrase 'ItemName' as part of an aggregate function."
when i'm writing the query like this :
```
string strSql = "SELECT Sum(OrderDetails.ItemStock),OrderDetails.ItemID FROM OrderDetails GROUP BY OrderDetails.ItemID ORDER BY SUM(OrderDetails.ItemStock) DESC";
```
it is ok<issue_comment>username_1: Error message `"The query does not include the specified phrase 'ItemName' as part of an aggregate function."` clearly says that you need to include column `ItemName` which is missing in your `group by` clause.
based on your columns in `select` statement you query should be as below , which will be all columns on which aggregate function not applied include in `group by` clause. that is requirement of `group by` clause in sql.
```
string strSql = "SELECT Sum(OrderDetails.ItemStock),
OrderDetails.ItemID,Items.ItemName,Items.ItemImage
FROM OrderDetails,Items
WHERE OrderDetails.ItemID = Items.ItemID
GROUP BY OrderDetails.ItemID,,Items.ItemName,Items.ItemImage
ORDER BY SUM(OrderDetails.ItemStock) DESC";
```
Upvotes: 2 <issue_comment>username_2: Learn to use explicit `JOIN` syntax! And, fix your aggregation as well:
```
SELECT SUM(od.ItemStock), od.ItemID, i.ItemName, i.ItemImage
FROM OrderDetails as od INNER JOIN
Items as i
ON od.ItemID = i.ItemID
GROUP BY od.ItemID, i.ItemName, i.ItemImage
ORDER BY SUM(od.ItemStock) DESC;
```
The fix to your problem is simply to include all the non-aggregated columns in the `GROUP BY`. But you should learn how to write clean SQL along the way.

2018/03/20 | 2,993 | 9,877 | <issue_start>username_0: I'm completely new to Ruby on Rails but I think I might be missing something obvious. I'm currently working on a webapp that scrapes auction websites. The bones of the app was created by someone else. I'm currently trying to add new website scrapes but they don't seem to be working.
I have read through some of the Nokogiri documentation, checked that the scraped information is indeed not being written to the database (the seeded URLs that are being targeted have been when I check via the rails console) and used the chrome extension CSS Selector Tester to check that I am targeting the correct CSS selectors. The record ids are correct when I check via the rails console.
I have put what I think are the important sections of code below, but I might be missing something that I don't realise is important.
The websites I'm having issues with are [Lot-art.com](https://www.lot-art.com/auction-search/?form_id=lot_search_form&page=1&mq=&q=Vase&ord=recent) & [Lot-Tissimo.com](https://lot-tissimo.com/en/cmd=s&lwr=&ww=Vase&xw=&srt=SN&wg=EUR&page=1)

```<issue_comment>username_1: `new` just initializes an instance but doesn't save the instance. Do you actually call `save` somewhere?
You have two options:
Call `save` on the item:
```
item = action.items.new(
# ...
)
item.save
```
Or use `create` instead of `new`:
```
item = action.items.create(
# ...
)
```

I am still having continuing issues with lot-tissimo although that appears to be from something else as other scrapers have issues such as scraping-hub's portia spiders.

2018/03/20 | 447 | 1,544 | <issue_start>username_0: How can I use Django 1.11 as default version in **pycharm** ?
Letting you know that I'm using **macOS** and default Django version is 2.0.3 !<issue_comment>username_1: Pycharm has nothing to do with Django version. You can just install django version you need.
Use: `pip3 install django==1.11`
>
> Note:
>
>
>
You can check your globally installed django version by typing:
```
python3
import django
django.VERSION
```
You will probably get 2.0.3 as global django version. So now you have to type:
```
pip3 install django==1.11
```
That will install django with version 1.11 as global. From now, whenever you will create new project via:
`django-admin startproject your_project`
Django version of that new project will be 1.11 by default
>
> And some advice:
>
>
>
Next time just use `virtualenv` or `virtualenvwrapper`, by using it you will set your libraries locally for each project
Upvotes: 2 <issue_comment>username_2: You can use `python virtualenv` to create a custom environment for your project with django version 1.11.
* <https://docs.python.org/3/library/venv.html>
* <https://www.jetbrains.com/help/pycharm-edu/creating-virtual-environment.html>
In your project folder :
```
python3 -m venv env
source env/bin/activate
pip install django=1.11
```
This will create a folder named `env` (`source` command activates this environment). You may need to install all your other dependencies.
In PyCharm, under project settings `Project Interpreter`, select this environment.

```
public function __construct(
ProductRepositoryInterface $productRepository,
SearchCriteriaBuilder $criteriaBuilder
) {
$this->productRepository = $productRepository;
$this->criteriaBuilder = $criteriaBuilder;
}
/**
* @return ProductInterface[]
*/
public function getProducts(): array
{
$categoryIdsToExport = $this->config->getCategoriesToExport();
return $this->productRepository->getList(
$this->criteriaBuilder
//It's Custom Filter from di.xml
->addFilter('category_id', $categoryIdsToExport, 'in')
//Here you cat filter products in standart Magento way
->addFilter('status', \Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED)
->addFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH)
->create()
)->getItems();
}
```
Unfortunately There are few info in stackexchange about "Search Criteria Unify Processing" - better and currently proper way to filter,sort models.
[Here Magento doc about Search Criteria Unify Processing](https://devdocs.magento.com/guides/v2.4/extension-dev-guide/searching-with-repositories.html#m2devgde-searchcriteria-unify-processing)
Also you can register your own CustomFilter to filter products.
See example in `vendor/magento/module-catalog/etc/di.xml` :
```
Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\FilterProcessor\ProductCategoryFilter
Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\FilterProcessor\ProductStoreFilter
Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\FilterProcessor\ProductStoreFilter
Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\FilterProcessor\ProductWebsiteFilter

in this look the ChangeDetection Category and change the alias property from c to cd for example an try again.

npm uninstall @schematics/angular --save
```
Afterwards, `ng generate component` worked for me.

2018/03/20 | 2,399 | 8,439 | <issue_start>username_0: **TL;DR: My question is how to bundle some of my sass files into single sass file?**
I've been developing an Angular component library and I package it with ng-packagr. Let's call it `@my-lib/ngx-components`.
Consumers of my lib will import my components like `@my-lib/ngx-components/navbar`.
I decided to add theming support to components.
For example, I have a navbar component with default colors (background, text, hover etc.) I want consumers of my library to be able to override these colors with their own theme. That's why I've written a `mixin` which takes a `$theme` input and override some css rules as follows (this is a basic version of what I have)
`_navbar-theme.sass`
```
@mixin navbar-theme($theme)
$primary-color: map-get($theme, primary-color)
$secondary-color: map-get($theme, secondary-color)
$color: map-get($theme, color)
.navbar
background-color: $primary-color
color: $color
&:hover
background-color: $secondary-color
```
Each component has its own `*-theme.sass` file.
I also have global `_theming.sass` file which imports all of these as follows
`_theming.sass`
```
@import './components/navbar/navbar-theme'
@import './components/button/button-theme'
@import './components/dropdown/dropdown-theme'
```
I want to export this `_theming.sass` file from my lib, so people can import this file in their own `sass` file as `@import '~@my-lib/ngx-components/theming'` and start using all of the `mixin`s available.
If they want to have custom `navbar`, `button` etc, they should be able to use those `mixin`s with single import.
I tried to make it look like angular-material theming setup.
At first, I have tried `node-sass` which is already in my dependencies. But, it tries to build sass into css so it omits mixins in the output file.
Then, I looked at what angular-material has done. They use [scss-bundle](https://github.com/SimplrJS/scss-bundle)
I thought "this is exactly what I want." However, it requires `scss` files, not `sass` files. It cannot read `sass` files.
Then, I thought "Okay, I can give up on sass and start using scss. How do I convert all those files to scss without going through them by hand". Then, I found [sass-convert](https://github.com/SassDoc/sass-convert). [In this question](https://stackoverflow.com/questions/26493111/is-it-possible-to-convert-whole-folder-with-convert-sass-scss-to-sass) it was said that I can use it within command line. However, when I install `sass-convert` with npm globally, it didn't give me a command line executable. I think I need `Gulp` to use it.
I've been avoding to use `Gulp` from the beginning, because it means another tool to learn and it adds complexity to codebase.
At this point, I feel like ["Hal fixing light bulb"](https://www.youtube.com/watch?v=AbSehcT19u0)
**TL;DR: My question is how to bundle some of my sass files into single sass file?**
Also, If you can come up with a solution that requires webpack, that's fine too.<issue_comment>username_1: Let's through your opinion or questions:

You need to know, what is your target audience. Mostly people using angular cli for create their app like template scratch.
So you need provide `css` bundle (people just want import your css) and `sass` bundle (who want to use your object or your mixin).

Firstly, you need to know that `@angular/material` doesn't export `sass` (they use scss) but they export css thene compiled by `scss-bundle` (as you mention it) see their [code](https://github.com/angular/material2/blob/fcc09089c38fb5d2d78db45f473908a924e5c14e/tools/sass_bundle.ts) and documentation [theme](https://material.angular.io/guide/theming#defining-a-custom-theme).

It is better you need transfer your code from sass to scss (by yourself), it would not much to do it (I think, I always write scss instead sass file).

Solution:
=========
1. Provide css and sass (scss better)
-------------------------------------
When you deliver your component libs, You have to provide `css` and `scss`. Beacuse angular cli doesn't provide `scss` loader by default.
Don't use `sass` file, use `scss` file see my refer answer on top.
**scss-bundle + webpack**
Since you have to provide css, you can you [webpack shell plugin](https://www.npmjs.com/package/webpack-shell-plugin) to bundle scss. Scss have provide cli, if you want to use cli.
2. Structure your scss
----------------------
Okay, let's take sample from bootstrap@4 module for this case. Bootstrap use structure like this ([Documents](https://getbootstrap.com/docs/4.0/getting-started/theming/#sass)):
```
scss
|-- _variables.scss
|-- _mixins.scss
|-- _functions.scss
|-- ...
|-- index.scss
```
inside `index.scss` will have like this:
```
@import 'variables'
@import 'mixins'
@import 'functions'
...
```
so, this `scss` you have to deliver beside `css`. Like `bootstrap` do, then `mixin` will available to consumer. Also this good approach when consumer to find `scss` file in `scss` folder (easy to pointing which is scss put in).
---
UPDATE
======
For bundle to single file you have to create task runner to do it. In your case you want to use webpack, you can create a plugin to do it.
Here example plugin:
[scss-bundle-plugin.js](https://github.com/username_1/hello-world-loader/blob/master/scripts/scss-bundle-plugin/scss-bundle-plugin.js)
call to you config webpack:
```
plugins: [
new webpack.NoEmitOnErrorsPlugin(),
new SCSSBundlePlugin({
file: path.join(__dirname, 'src/index.scss')
})
],
```
To try playground, checkout [hello-world-loader](https://github.com/username_1/hello-world-loader) then:
```
# install dependency
npm install
# try play ground
npm run webpack
```
it will create file `_theme.scss` at `./dist`.
My advice don't use webpack, use task runner instead (gulp or grunt) for this simple case. Webpack too advance and hard to write task.

I've used small module [bundle-scss](https://www.npmjs.com/package/bundle-scss?activeTab=readme)
It bundles files by file name mask. So you need to pass correct mask like `./src/**/*.theme.scss` specify destination file and maybe your custom sort-order
You don't have to create one entry point file with all imports. `bundle-scss` will get all files by mask analyze all imports and include this files as well
Upvotes: 0 <issue_comment>username_3: There is also a widely used package, called [scss-bundle](https://github.com/reactway/scss-bundle).
It is quite simple to use, you just create a config file with all relevant configuration and then run scss-bundle.
This for example will use all scss files, imported in entry.scss and move it to out.scss. All imports will be resolved, except for angular themes in this example, like `@import '~@angular/material/theming';`.
scss-bundle.config.json:
```
{
"bundlerOptions": {
"entryFile": "my-project/src/entry.scss",
"outFile": "dist/out.scss",
"rootDir": "my-project/src",
"project": "../../",
"ignoreImports": [
"~@angular/.*"
],
"logLevel": "debug"
}

I have a question regarding a schema of my database. I'm writing RESTful application using Spring. The idea is to allow user to create his own diet based on products stored in DB.
So I came to creating entity Meal, which should consist of Products and amount of those products. It seems like natural way to have something like this is using Map. Problem is, that as I have read there is a problem with mapping such class to JSON Object, which I would like to send to clients browser. My other idea was to store List of objects like ProductWithQuantity instead of such map, but I'm a little worried that DB would be quickly flooded by entries like 1 glass of milk, 2 glasses of milk, 1.1243 glasses of milk and so on.
So my question is - do you have any better idea for the schema for such purpose? ;)<issue_comment>username_1: Let's through your opinion or questions:

2018/03/20 | 1,522 | 5,190 | <issue_start>username_0: I have a NodeJS lambda function that I run on AWS. I want to write a simple test for the `.handler` function.
**CODE**
Here is the `index.js` code:
```
// importing dependencies
var mySQLWriter = require('./mySQLWriterService');
exports.handler = function(event, context, callback) {
console.log('Printing out JSON.stringify(event): ');
console.log(JSON.stringify(event));
event.Records.forEach((record) => {
if (record.eventName === 'INSERT') {
console.log('We have an INSERT happening.');
mySQLWriter(record, callback);
}
});
};
```
I want to write a simple test that would pass if `mySQLWriter` is called.
Using Mocha and Chai and with help from dashmud below, I have attempted to do this, but it isn't working, here is my `indexTests.js` code:
```
const chai = require('chai');
const expect = chai.expect;
const spies = require('chai-spies');
chai.use(spies);
const appStart = require('../index');
const mySQLWriter = require('../mySQLWriterService');
describe('lambda function', () => {
it('should call the mySQLWriter() function', () => {
const spy = chai.spy.on(mySQLWriter, 'mySQLWriter');
let event = {
Records: [
{
eventName: 'INSERT',
dynamodb: {
NewImage: {
DeviceId: { S: 'Device 000' },
TimeStamp: { S: '2018-03-20T11:15:31.668Z' },

}
}
}
]
};
const context = {};
appStart.handler(event, context, () => {
expect(spy).to.have.been.called();
done();
})

Upvotes: 0 <issue_comment>username_2: Your `appStart` is just a module. You need to call the `handler` inside your `appStart` (`index.js`) and do your assertions inside the callback.
```
const chai = require('chai');
const expect = chai.expect;
const spies = require('chai-spies');
chai.use(spies);
const appStart = require('../index');
describe('lambda function', () => {
it('should call the mySQLWriter() function', done => {
const spy = chai.spy.on(mySQLWriter, 'mySQLWriter');
const event = {};
const context = {};
appStart.handler(event, context, () => {
expect(spy).to.have.been.called();
done();
})
});
});
```

Update based on comment and updated question:
Based on your screenshot, it seems like `mySQLWriterService.js` exports an object with a `mySQLWriter` function.
This will not work.
```
var mySQLWriter = require('./mySQLWriterService');
```
I think is should be like this:
```
const mySQLWriter = require('./mySQLWriterService').mysqlWriter;
```
(I'm not 100% sure as you did not include the code inside your `mySQLWriterService.js`.)
P.S. Don't use `var`. Ever.

2018/03/20 | 453 | 1,610 | <issue_start>username_0: I'm currently trying to make my script dynamic and looking for a way to grab my file data with wildcards.
This is my old code:
```
#process .csv into the database
if(($handle = fopen("9_filename.csv", "r")))
```
Here I just grab a file through a string. Works fine. But it's static and I need to process 20 files per week at once, which change the calendar week in the file name.
So after some research I found the "glob" function, which allows me to set wildcards. So I assign a variable with the "glob" function. A var\_dump returns the correct file name "9\_filename.csv". So the string exists.
This is my new code:
```
#variables
$file = glob("*_filename.csv");
#process .csv into the database
if(($handle = fopen($file, "r")))
```
Unfortunately as a result I get the following error:

And fopen can only handle one at a time, so you need to feed them one at a time:

foreach($files as $file){
#process .csv into the database

```

I'm trying to get the "state" property in another file so I
```
import module from './veux'
```
then
```
const { state } = module
```
however `state` is **undefined** which is weird because `console.log(module)` shows me that `module.state` is present
I'm new to this ES6-7 flow so but what exactly am I doing wrong here?<issue_comment>username_1: Since you have exported the object `{module, plugin}` as `default export`
after importing like
```
import module from './veux'
```
module will have structure like
```
module = {
module: { state, mutations, actions, getters },
plugin
}
```
so in order to access state, you will write `module.module.state` or
```
const {module: {state}} = module; // nested destructuring
console.log(state)
```
an easier to understand and readable method would be to export your module with named export like
```
export const module = { state, mutations, actions, getters }
export default plugin
```
and import it like
```
import plugin, { module } from './veux'
```
after which you can do
```
const { state } = module;

No, you're importing the whole default-exported object (with its `module` and `plugin` properties) as `module`. The property would be `module.module.state`.

Don't. Use named exports for exporting multiple things:
```
export const module = { state, mutations, actions, getters }
export { plugin }
```
then you can do
```
import { module } from './veux'
const { state } = module

Instead, I am getting `{ ,0, ,1, ,1}`. As you can see it is working correctly for even positions but giving blank space in odd positions. I tried casting it to **int** which gives `{0,48,0,49,0,49}` while using **Character.getNumericValue(s\_td[i])** gives `{-1,0,-1,1,-1,1}`.
Thanks in advance!<issue_comment>username_1: Since you have exported the object `{module, plugin}` as `default export`
after importing like
```
import module from './veux'
```
module will have structure like
```
module = {
module: { state, mutations, actions, getters },
plugin
}
```
so in order to access state, you will write `module.module.state` or
```
const {module: {state}} = module; // nested destructuring
console.log(state)
```
an easier to understand and readable method would be to export your module with named export like
```
export const module = { state, mutations, actions, getters }
export default plugin
```
and import it like
```
import plugin, { module } from './veux'
```
after which you can do
```
const { state } = module;
```

```
import { module } from './veux';
```

No, you're importing the whole default-exported object (with its `module` and `plugin` properties) as `module`. The property would be `module.module.state`.

Don't. Use named exports for exporting multiple things:
```
export const module = { state, mutations, actions, getters }
export { plugin }
```
then you can do
```
import { module } from './veux'
const { state } = module
```

Sorry for not posting any code, but I have no idea how I could achieve this. All solutions I know and all I found are based on JS. [Example](https://stackoverflow.com/a/26583062/1457385).
I already add to the HTML if it does not exist yet, but at least images are often displayed way too big.
All images are provided to `WKWebView` by a `WKURLSchemeHandler`.<issue_comment>username_1: Please put
```
```
inside your tag.

extension String {
mutating func fitContentToScreen() {
self.add(prefix: "")
}
}
```
You add this header line to html content to fit screen.

```
public function get_loginsecuritydetails($security_date,$apt_id) {
$sql = "SELECT s.* , IF( DATE( s.security_date ) = DATE( '$security_date' ) , 1, 0 ) AS loginstatus,a.agency_companyname FROM security s JOIN agency a ON(a.agency_id=s.security_cat) WHERE apartment_id='$apt_id'; ";
$res=mysqli_query($sql) or die(mysqli_error());
return $res;
}
```<issue_comment>username_1: You can convert it in codeigniter query builder as below:
```
$this->db->select("s.* , IF( DATE( s.security_date ) = DATE( '$security_date' ) , 1, 0 ) AS loginstatus,a.agency_companyname");
$this->db->join("agency as a","a.agency_id=s.security_cat");
$this->db->where('apartment_id',$apt_id);
$query = $this->db->get('security as s');
$result = $query->result();
return $result;
```

Try like this -
$this->db->select("s.* , IF( DATE( s.security_date ) = DATE( '$security_date' ) , 1, 0 ) AS loginstatus,a.agency_companyname");
$this->db->join("agency as a","a.agency_id=s.security_cat");
$this->db->where('apartment_id',$apt_id);
$querys = $this->db->get('security as s');
$result = $querys->result();
```

Having said that the easiest solution is to simply run the query like:
```
$this->db->query('YOUR QUERY HERE');
```
The part that says 'YOUR QUERY HERE' should be replaced with the actual query like:
```
$this->db->query("SELECT s.* , IF( DATE( s.security_date ) = DATE( '$security_date' ) , 1, 0 ) AS loginstatus,a.agency_companyname FROM security s JOIN agency a ON(a.agency_id=s.security_cat) WHERE apartment_id='$apt_id'");
```
Now I'm pretty sure you'd want to clean this up and start using paramaters inside your query instead of PHP variables.
So you should look into the query builder class, <https://www.codeigniter.com/userguide3/database/query_builder.html>

2018/03/20 | 303 | 1,098 | <issue_start>username_0: This is my code:
```
interface a {}
class b{}
class c extends b implements a{}
class d extends b{}
class e{
public void makeItWork(){
b[] bees = new b[] {new c(), new d()};
for (b bee: bees){
if (bee instanceof a) {
a beeA = (a) bee;
//how to call the method test if object bee conforms the the interface?
test(beeA.getClass(), beeA);
//this goes wrong
}
}
}
public void test(Class classType, T concrete){
}
}
```
Besides maybe the bad design, I would like to know if it is possible to call the method `test` on objects who implements the interface `a`.<issue_comment>username_1: your `test` method doesn't need a generic type parameter.
You can define it as:
```
public void test(Class extends a classType, a concrete) {
}
```
P.S. please use capitalized class names.

public void test(a concrete) {
}
