I would create a class method like System.sleep() and use this in your application. System.sleep() can be mocked then. | 1 | 1 | 0 | I am writing an application that would asynchronously trigger some events. The test looks like this: set everything up, sleep for sometime, check that event has triggered.
However because of that waiting the test takes quite a time to run - I'm waiting for about 10 seconds on every test. I feel that my tests are slow - there are other places where I can speed them up, but this sleeping seems the most obvious place to speed it up.
What would be the correct way to eliminate that sleep? Is there some way to cheat datetime or something like that?
The application is a tornado-based web app and async events are triggered with IOLoop, so I don't have a way to directly trigger it myself.
Edit: more details.
The test is a kind of integration test, where I am willing to mock the 3rd party code, but don't want to directly trigger my own code.
The test is to verify that a certain message is sent using websocket and is processed correctly in the browser. Message is sent after a certain timeout which is started at the moment the client connects to the websocket handler. The timeout value is taken as a difference between datetime.now() at the moment of connection and a value in database. The value is artificially set to be datetime.now() - 5 seconds before using selenium to request the page. Since loading the page requires some time and could be a bit random on different machines I don't think reducing the 5 seconds time gap would be wise. Loading the page after timeout will produce a different result (no websocket message should be sent).
So the problem is to somehow force tornado's IOLoop to send the message at any moment after the websocket is connected - if that happened in 0.5 seconds after setting the database value, 4.5 seconds left to wait and I want to try and eliminate that delay.
Two obvious places to mock are IOLoop itself and datetime.now(). the question is now which one I should monkey-patch and how. | Mocking "sleep" | 0.099668 | 0 | 1 | 481 |

it is a conformant implementation of Python 2's syntax - and the differences to Python3 are just the one you will find documented everywhere.
I don't know where jython stands in terms of implementation of Python's stdlib - but I believe it has most of Python's 2.7 stdlib in place and working - some modules won't work, like "ctypes" for example. But as far as the language constructs go, you will be fine.
(IMO it is a good tool, not only for what you want, but a nice tool for exploring Java's libraries themselves in an interactive way, since you can use any Java class from the jython interactive shell)
As for the comments talking about unavailable modules: those are 3rd party modules installable on CPython. You certainly don't need them to get the language constructs, like you want. It is a trade off: you loose a lot of the Python ecosystem, but you can use the Java ecosystem in its place. And certainly, when starting a new project, you can just use normal CPython with whatever modules you need: the language is the same. | 1 | 3 | 0 | If I learn Jython first, does that mean I will also be learning all of the Python language?

As suggested in the comments above installed packages by downloading the source and compiled them in a machine which had glibc2.5 then created binary executable of my pygtk app using pyinstaller
I had tried compiling packages earlier also, but weren't checking the ./configure output properly. The problem was, I was trying to install gtk and pygtk without installing cairo and pango. So pygtk skipped building gtk packages because it did not find any cairo package. This was mentioned in the ./ configure script but I had not checked that.
Summarizing:
To configure pygtk to python need to folow these steps
install sqlite-devel #If sqlite needed
install python(2.7)
install gtk(2.24.0) -> requires glib(2.27.3), atk(1.29.2), cairo(1.8.10), pango(1.22.4), gdk-pixbuf(2.21.3)
install pygtk(2.24.0) -> requires pygobject-2.28.3, pycairo(1.8.10)
All the above packages must be compiled to the same prefix, and need to set the PYTHON and PATHONPATH environment variables. The versions of packages also play major role. Added version in parenthesis that worked for me.
There are many dependencies while installing some of the packages so I had to install following packages using yum:
libxext, librender, gettext, zlib, libgtk2-devel | 1 | 1 | 0 | I have developed a pygtk application and i need to release it to customers.
I am using python 2.7, pygtk 2.2 in ubuntu.
My question is how can I bundle the required packages(python, pygtk, gobject) together with my application, so that even if these packages are not installed in client machine I can run my application.
I tried with pyinstaller but, the executable depends on the glibc i.e executable created with higher glibc version will not work with the machine which has lower glibc version.
So is there any way to create a release directory which includes all the packages required so that I can run my application in any system without installing the packages.

PyOpenGL (the Mike Fletcher version, right?) is the best Python OpenGL API I know of. It has support for OpenGL 3 and 4 and is just very nice and Pythonic.
PyQt itself only supports OpenGL 2, but PyOpenGL will run inside a PyQt context. Since PyQt does have a Python 3 version, this combination should meet your needs.
For the GUI stuff I prefer wxPython, but as you note that hasn't been updated for Python 3 yet. You could take a look at the wxPython Phoenix project, but that's very much a work in progress.
Pyglet is also quite nice but has less GUI functionality that wxPython or PyQt. Think of it as the equivalent of GLUT. The Python 3 version is currently in alpha, but given that it's not a complete rewrite I'd expect it to be stable very soon.
Hope this helps. | 1 | 0 | 0 | I want to write a visualization for some complex scientific data in Python. I have done a similar thing a few years ago in Objective-C/Cocoa/OpenGL. The visualization will contain some fancy shader programs, so at least OpenGL 3.0 is required. Also, I need to draw a window and do some mouse/keyboard handling. Some GUI widgets would be nice, but not required. Python 3 support is highly desirable.
I looked into:
PyOpenGL, which has no window/mouse/keyboard handling.
PyGlet, which only supports Python 2.7.
PyQt, which only supports OpenGL 2.0.
PySide, which is pretty much dead, and stuck in Qt 4.7.

parameter is a file or folder in current directory | 1 | 2 | 0 | I am working in python. my problem is I have several strings and I have to detect which part of them look like a path and then normalize the ones that are actual paths.
e.g. I have several different strings like follows :
1. ..\..\..\Workspace
2. C:\source\Workspace
3. -B..\..\source
4. -build..\..\work\source..\workspace
5. -HD:\abc\bds\Workspace
Basically some strings are paths straightaway and some have a trailing - attached to them. The length of option string is variable.
In the above example strings 3, 4, 5 contain a path string pre-attached with an option -B, -build, -H respectively.
The problem is how to detect from the above examples, which part of the string is a path and which is not. The options are not fixed so I can't just check given string's head for pre-specified options.
The only way to go forward is taking the sub-string starting from .. or one character before : (e.g. C: or D:).
So the question is that is there any generalized way of doing this or does python provide any function to take truncated portion of a string starting from any particular position ?
any answer which satisfies above 5 examples is cool even though it is kinda overfitting.
The code that I am currently using for e.g. 2 and 5 is : path = path[path.find(':')-1:]
and for others its path = path[path.find('.'):]. But this is not generalized and uncool. So I am looking for a better algorithm or solution. | find if string is a path | 0 | 0 | 0 | 6,380 |

# inside my views file

However, my problem is that debugging from within the *register_POST* method, the self.request.POST dict is empty. Also, when I check the debug button on the page, the POST request is registered in the list, but the POST data is empty.

Create a buffer, drop the ids from your zeromq messages in there and let you worker poll regularly this id-pool. If it fails retrieving an object for the id from the database, let the id sit in the pool until the next poll, else remove the id from the pool.
You have to deal somehow with the asynchronous behaviour of your system. When the ids arrive constantly before persisting the object in the database, it doesnt matter whether pooling the ids (and re-polling the the same id) reduces throughput, because the bottleneck is earlier.
An upside is, you could run multiple frontends in front of this. | 1 | 1 | 0 | Inside an web application ( Pyramid ) I create certain objects on POST which need some work done on them ( mainly fetching something from the web ). These objects are persisted to a PostgreSQL database with the help of SQLAlchemy. Since these tasks can take a while it is not done inside the request handler but rather offloaded to a daemon process on a different host. When the object is created I take it's ID ( which is a client side generated UUID ) and send it via ZeroMQ to the daemon process. The daemon receives the ID, and fetches the object from the database, does it's work and writes the result to the database.
Problem: The daemon can receive the ID before it's creating transaction is committed. Since we are using pyramid_tm, all database transactions are committed when the request handler returns without an error and I would rather like to leave it this way. On my dev system everything runs on the same box, so ZeroMQ is lightning fast. On the production system this is most likely not an issue since web application and daemon run on different hosts but I don't want to count on this.
This problem only recently manifested itself since we previously used MongoDB with a write_convern of 2. Having only two database servers the write on the entity always blocked the web-request until the entity was persisted ( which is obviously is not the greatest idea ).
Has anyone run into a similar problem?
How did you solve it?
I see multiple possible solutions, but most of them don't satisfy me:
Flushing the transaction manually before triggering the ZMQ message. However, I currently use SQLAlchemy after_created event to trigger it and this is really nice since it decouples this process completely and thus eliminating the risk of "forgetting" to tell the daemon to work. Also think that I still would need a READ UNCOMMITTED isolation level on the daemon side, is this correct?
Adding a timestamp to the ZMQ message, causing the worker thread that received the message, to wait before processing the object. This obviously limits the throughput.
Dish ZMQ completely and simply poll the database. Noooo! | ZeroMQ is too fast for database transaction | 0 | 1 | 0 | 2,062 |

According with my high traffic on my app, I am having issues with memory data after 30 minutes start to appear as no saved, however queries are being executed on postgres ( I have checked that on last activity )
Fake Solution
I have amke a script that restart my app, postgres ang pgbouncer, however this is a wrong solution, because each time that I restart my app, gps get disconnected, and must to reconnected again
Posible Solution
I am thinking on a high availability solution based on a Data Layer, where each time when database have to be restarted or something happened, a txt file store data from gps devices.
For get it, I am thing on a no unique connection, I am thinking on a simple connection each time one data must be saved, and then test database, like a pooler, and then if database connection is wrong, the txt file store it, until database is ok again, and the other process read txt file and send info to database
Question
Since I am thinking on a app data pooler and a single connection each time when this data must be saved for try to no lost data, I want to know
Is ok making single connection each time that data is saved for this
kind of app, knowing that connections will be done more than 100 times
each 5 seconds?
As I said, my question is too simple, which one is the right way on working with db connections on a high traffic app? single connections per query or shared unique connection for all app.
The reason on looking this single question, is looking for the right way on working with db connections considering memory resources.
I am not looking for solve postgresql issues or performance, just to know the right way on working with this kind of applications. And that is the reason on give as much of possible about my application
Note
One more thing,I have seen one vote to close this question, that is related to no clear question, when the question is titled with the word "question" and was marked on italic, now I have marked as gray for notice people that dont read the word "question"

loop over all files in a folder with a for-loop and the os.listdir method
check if the file belongs to the data collection, for example by using something like str.endswith('.csv')
convert the filename to a full path by using os.path.join
read the data to a numpy array with numpy.loadtxt

Here is the relevant part of my PATH before editing:
C:\Python27\;
C:\Python27\Lib\site-packages\pip\;
C:\Python27\Scripts;
C:\Python27\Lib\site-packages\django\bin;

Then in the middle part of that window check the the shell path is set to "cmd.exe" or not, if not then set it to "cmd.exe" (it will have it's path associated with it so no need to do anything just click on "cmd.exe" from the drop down list) then click on "apply" button below and click "ok".

My take on it is due to django's intense desire to separate view logic from the template.
The request object is the gateway to all data that view logic is built from (given what the browser sent us, do X, Y, Z) - therefore allowing it in the templates is akin to giving the template huge amounts of control which should be placed in the view under normal circumstances. The idea is to populate the template context with specifics, not everything.
Removing them is just some more encouragement that "most things should be done in the view". The common django.contrib apps mostly don't rely on it, if it's not required by default.
And of course, that's further proof the request object isn't necessary in the template except for special use cases.
That's my take, anyways. | 1 | 5 | 0 | I was troubleshooting a problem with obtaining the request obj with a new project and realized "django.core.context_processors.request" was commented in vanilla installs of Django.

If x=2, f(a,b,x) = 1 because if one divide 15 into 3 parts, the number 2 is in the first part.
If x=7, f(a,b,x) = 2 because if one divide 15 into 3 parts, the number 7 is in the second part.
If x=15, f(a,b,x) = 3 because if one divide 15 into 3 parts, the number 15 is in the third part.
If x<0 or >15 the results are irrelevant to me.

No, it has to be escaped like that just before it ends up in an HTML page - step (5) above.
The right type of escaping has to be applied when text is injected into a new surrounding context. That means you HTML-encode data at the moment you include it in an HTML page. Ideally you are using a modern templating system that will do that escaping for you automatically.
(Similarly if you include data in a JavaScript string literal in a <script> block, you have to JS-encode it; if you include data in in a stylesheet rule you have to CSS-encode it, and so on. If we were using SQL queries with data injected into their strings then we would need to do SQL-escaping, but luckily Mongo queries are typically done with JavaScript objects rather than a string language, so there is no escaping to worry about.)
The database is not an HTML context so HTML-encoding input data on the way to the database is not the right thing to do.
(There are also other sources of XSS than injections, most commonly unsafe URL schemes.) | 1 | 7 | 0 | I'm trying to determine the best practices for storing and displaying user input in MongoDB. Obviously, in SQL databases, all user input needs to be encoded to prevent injection attacks. However, my understanding is that with MongoDB we need to be more worried about XSS attacks, so does user input need to be encoded on the server before being stored in mongo? Or, is it enough to simply encode the string immediately before it is displayed on the client side using a template library like handlebars?
Here's the flow I'm talking about:
On the client side, user updates their name to "<script>alert('hi');</script>".
Does this need to be escaped to "<script>alert('hi');</script>" before sending it to the server?
The updated string is passed to the server in a JSON document via an ajax request.
The server stores the string in mongodb under "user.name".
Does the server need to escape the string in the same way just to be safe? Would it have to first un-escape the string before fully escaping so as to not double up on the '&'?
Later, user info is requested by client, and the name string is sent in JSON ajax response.
Immediately before display, user name is encoded using something like _.escape(name).
Would this flow display the correct information and be safe from XSS attacks? What about about unicode characters like Chinese characters?
This also could change how text search would need to be done, as the search term may need to be encoded before starting the search if all user text is encoded.
