Assuming sess is the session, you can do sess.execute(CreateTable(tenantX_tableY)) instead.
EDIT: CreateTable is only one of the things being done when calling table.create(). Use table.create(sess.connection()) instead. | 1 | 0 | 0 | 0 | I'm using Sqlalchemy in a multitenant Flask application and need to create tables on the fly when a new tenant is added. I've been using Table.create to create individual tables within a new Postgres schema (along with search_path modifications) and this works quite well.
The limitation I've found is that the Table.create method blocks if there is anything pending in the current transaction. I have to commit the transaction right before the .create call or it will block. It doesn't appear to be blocked in Sqlalchemy because you can't Ctrl-C it. You have to kill the process. So, I'm assuming it's something further down in Postgres.
I've read in other answers that CREATE TABLE is transactional and can be rolled back, so I'm presuming this should be working. I've tried starting a new transaction with the current engine and using that for the table create (vs. the current Flask one) but that hasn't helped either.
Does anybody know how to get this to work without an early commit (and risking partial dangling data)?

The lib provides a high-level access to a custom in-house database. At this point, I know that I could send the lib version along with the query request, and show the user a message with the result that they need to install an update.

The simplest approach would be to always let your program use the same client and let it sync the file. You could let your program call p4 sync and see if you get a new version or not. Let it continue if you get a new version. This approach has the advantage that you don't need to remember any states/version from the previous run of your program.
If you don't like using a fixed client you could let your program always check the current head revision of the file in question:
p4 fstat //depot/path/yourfile |grep headRev | sed 's/.*headRev \(.*\)/\1/'
You could store that version for the next run of your program in some temp file and compare versions each time.
If you run your program at fixed times (e.g. via cron) you could check the last modification time (either with p4 filelog or with p4 fstat) and if the time is between the time of the last run and the current time then you need to process the file. This option is a bit intricate since you need to parse those different time formats. | 1 | 0 | 0 | 0 | I'm writing a python app that connects to perforce on a daily basis.

The topic is function arguments that can semantically be expressed in many different ways. For example, to give a file to a function, you could either give the file directly, or you could give a string, which is the path to the file. To specify a number, you might allow an integer as an argument, or maybe you might allow a string (the numeral), or you might even allow a string such as "one". Another example might be a function that takes a list (of numbers, say), but as a convenience, it will convert a number into a list containing one element: that number.
Is there a more or less standard approach in Python to allowing this sort of flexibility? It certainly complicates the code for a program if you're not certain what types the arguments are, so my guess would be to try factor out the convenience functions into just one place, instead of scattered everywhere, but I don't really know how best to do that kind of factoring. | Flexible Arguments in Python | 0 | 0 | 1 | 0 | 0 | 1,455 |

In windows 7 (64bit) windows explorer when I right clicked a Python file and selected "edit with IDLE" the editor opens properly but when I run (or f5) the Python 3.3.1 program, it fails with the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." error message. All other methods of starting IDLE for running my python 3.3.1 programs worked perfectly.
Even the "Send to" method worked but it was unacceptably clunky. I've spend four days (so far) researching this and trying various things including reinstalling Python many times.
And NO it's not the FireWall blocking it. I've tried totally turning Firewall off and it had no effect.
Here's an important clue: In the beginning I installed and configured python 3.3 64 bit and everything worked including running from "edit with IDLE" but then recently when I needed a library only available in Python 2 I installed python 2.7.4 and from that point on the stated problem began. At one point I completely removed all traces of both versions and reinstalled Python 3.3.1 64 bit. Problem remained.
Then I tried have both 32 bit versions installed but still no luck. Then at some point in my muddling around I lost the option to "edit with IDLE" and spent a day trying everything including editing in Regedit. No luck there either. I reinstalled Python 3.3.1 still no "edit with IDLE" then Finally I uninstalled all versions of Python and I removed python references to environment variables PATH and PYTHONPATH. Then I Deleted all the Python related keys in the windows registry, deleted the C:\python33 directory that the uninstall didn't bother to delete. Overkill, of course, then I restarted windows and installed Python 3.3.1 64 bit version again and thankfully the option to 'edit with IDLE' was back.

I haven't used IDLE for a few months and decided to try if it works properly with newly installed python3.3 (on Linux Mint 13 x86). In between I made iptables setup much more aggressive and apparently it blocked idle-python3.3 from connecting to the Python RPC server.

In windows 7 (64bit) windows explorer when I right clicked a Python file and selected "edit with IDLE" the editor opens properly but when I run (or f5) the Python 3.3.1 program, it fails with the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." error message. All other methods of starting IDLE for running my python 3.3.1 programs worked perfectly.
Even the "Send to" method worked but it was unacceptably clunky. I've spend four days (so far) researching this and trying various things including reinstalling Python many times.
And NO it's not the FireWall blocking it. I've tried totally turning Firewall off and it had no effect.
Here's an important clue: In the beginning I installed and configured python 3.3 64 bit and everything worked including running from "edit with IDLE" but then recently when I needed a library only available in Python 2 I installed python 2.7.4 and from that point on the stated problem began. At one point I completely removed all traces of both versions and reinstalled Python 3.3.1 64 bit. Problem remained.
Then I tried have both 32 bit versions installed but still no luck. Then at some point in my muddling around I lost the option to "edit with IDLE" and spent a day trying everything including editing in Regedit. No luck there either. I reinstalled Python 3.3.1 still no "edit with IDLE" then Finally I uninstalled all versions of Python and I removed python references to environment variables PATH and PYTHONPATH. Then I Deleted all the Python related keys in the windows registry, deleted the C:\python33 directory that the uninstall didn't bother to delete.

I saw the same errors today. I tracked down the cause for me, hopefully it'll help you. I had IDLE open in the background for days. Today I tried to run a script in IDLE, and got the "IDLE's subprocess didn't make connection. Either IDLE can't start a subprocess or personal firewall software is blocking the connection." errors. So I closed all IDLE windows, and tried to restart IDLE. That then caused the same errors to pop up, and now IDLE wouldn't open successfully.
The cause was an extra pythonw.exe process running in the background. If I open up an instance of IDLE, then open a second, the second has issues connecting, and closes. But it does not close the instances of pythonw.exe that it opened, one is left running in the background. That extra instance then prevents future attempts to open IDLE.
Opening up Task Manager and killing all pythonw.exe processes fixed IDLE, and now it functions properly on my machine (1 instance open at a time though!). | 11 | 10 | 0 | 0 | Resolved April 15, 2013.

I'm questioning how Python implements the safety of memory areas and would like to know more about it, mainly because i'm curious :)

ld_preload to replace the functionality of the string handling of Python on a lower level.
One other option which is a bit easier was to develop my own C library that has more functionality then what Python offers through the standard string handling.
Mainly the C code has a shread() function that writes over the memory area where the string "was" stored and some other error checks.
However, @Ber gave me a good enough answer to start developing my own solution since (as he pointed out) there is no secure method in Python and python stores strings in way to many places and relies on the OS (which, on it's own isn't a bad thing except when you don't trust the OS you are installing your realtively secure application on). | 2 | 5 | 0 | 0 | Say i store a password in plain text in a variable called passWd as a string.

You can then process your stuff in a seperate thread in a synchronous manner and you won't have to worry about blocking at all. Well, Python is not suited for CPU bound tasks in the first place, so you should also think of spawning subprocesses. | 1 | 16 | 0 | 0 | I have recently been working on a pet project in python using flask. It is a simple pastebin with server-side syntax highlighting support with pygments. Because this is a costly task, I delegated the syntax highlighting to a celery task queue and in the request handler I'm waiting for it to finish. Needless to say this does no more than alleviate CPU usage to another worker, because waiting for a result still locks the connection to the webserver.
Despite my instincts telling me to avoid premature optimization like the plague, I still couldn't help myself from looking into async.
Async
If have been following python web development lately, you surely have seen that async is everywhere. What async does is bringing back cooperative-multitasking, meaning each "thread" decides when and where to yield to another. This non-preemptive process is more efficient than OS-threads, but still has it's drawbacks. At the moment there seem to be 2 major approaches:
event/callback style multitasking
coroutines
The first one provides concurrency through loosely-coupled components executed in an event loop. Although this is safer with respect to race conditions and provides for more consistency, it is considerably less intuitive and harder to code than preemptive multitasking.
The other one is a more traditional solution, closer to threaded programming style, the programmer only having to manually switch context. Although more prone to race-conditions and deadlocks, it provides an easy drop-in solution.
Most async work at the moment is done on what is known as IO-bound tasks, tasks that block to wait for input or output. This is usually accomplished through the use of polling and timeout based functions that can be called and if they return negatively, context can be switched.
Despite the name, this could be applied to CPU-bound tasks too, which can be delegated to another worker(thread, process, etc) and then non-blockingly waited for to yield. Ideally, these tasks would be written in an async-friendly manner, but realistically this would imply separating code into small enough chunks not to block, preferably without scattering context switches after every line of code. This is especially inconvenient for existing synchronous libraries.
Due to the convenience, I settled on using gevent for async work and was wondering how is to be dealt with CPU-bound tasks in an async environment(using futures, celery, etc?).
How to use async execution models(gevent in this case) with traditional web frameworks such as flask? What are some commonly agreed-upon solutions to these problems in python(futures, task queues)?
EDIT: To be more specific - How to use gevent with flask and how to deal with CPU-bound tasks in this context?
EDIT2: Considering how Python has the GIL which prevents optimal execution of threaded code, this leaves only the multiprocessing option, in my case at least. This means either using concurrent.futures or some other external service dealing with processing(can open the doors for even something language agnostic).

I don't know for sure that this is a PyCharm issue, but that's my best guess. Here's a description:
When I use the "Debug" control to start the app, webpages refresh automatically as I navigate from one page to another. That is, if I start at page A, navigate to page B, take some action that changes what A should look like, and navigate back to A, the change appears.
However, when I use the "Run" control to start the app, with no other changes, webpages do not automatically refresh. In that same scenario, when I navigate back to A, the old version of that webpage appears. I need to click my browser's Refresh control to see the updated page.
Please tell me how to stop the browser from displaying cached pages in Run mode. I haven't tried publishing this to our GAE website yet, and hopefully it won't happen there, but I need Run mode for performance on the video tutorial I'm creating.

And if you look at other implementations such as PyPy, IronPython, Jython etc., you won't have any luck with .pyc files at all.
Besides, .pyc files correspond to one .py file. What you (probably) have in mind are libraries which include a part written in C.

Unlike compiled languages, or even Python modules written in C, it is not a technical requirement that these files exist in the first place - if it was, you wouldn't be able to put your own scripts directly into python and have them run without a compile step.
Any library that strictly requires a build step before it is installed certainly has a component that compiles to native code - which certainly isn't cross-platform. For any pure-python library, it is always sufficient to put the module's source directory tree somewhere in your PYTHONPATH, having copied it directly from the archive you downloaded it in. | 2 | 6 | 0 | 0 | If I am right in understanding, Python compile files are cross platform.

ok: for key in x: print(x[key])
seems to be a tuple. dont know how to deal with, I would like to make as many dictionarys out of the transactions-tuple as there are. So sort of
for every tuple make dict[x] with tuple in it.
I know some mysql, in the end I want to have a table with one transaction per line, sorted chronologically, so i can build a chart of the transaction prices or some sort of 2-dimensional array, that i can acces by array[x][y].

For example, I know you can check the authentication token of the user and see if he is still 'actively logged in', but this doesn't tell me much, since the user could technically be logged in for two weeks, though only actively on the site for one minute of that duration. last_login would be equally unhelpful.

Current best practice is to store passwords salted and hashed. That is, when the user creates a new account and enters a password, you build a string from the password plus user name plus a "salt" (which is just a small string that's the same for everyone on your site--this is to thwart rainbow table attacks). Then you run that string through a good hash algorithm--something like SHA1 is fine (even MD5 is more than adequate, despite reports to the contrary). You certainly don't need anything like AES. Anyway, now that you have a hash, you store the hash in the database, and not the password. Even a strong cipher like AES is useless if don't do the rest right.
Next time the user logs in, you do the same: add his password to user name and salt, hash that, and compare the hash to what's stored. There's no way, even in principle, for you to know what his password was, so no way for an attacker to find it even if they get your database and know your algorithm and salt. | 1 | 1 | 0 | 0 | issue
I am writing an application in python. It takes care of contacts and other information about a person. I want to prompt the user for a master key every time that he/she wants to perform a major operation. I have everything figured out. The whole application is ready and works well. But I store the master key in a file. This file is easily readable in the plain text form. And my friends who tried using this said that the software is useless if I don't apply a strong encryption algorithm as users would simply trust the application with the details that can be easily stolen.
goal
To store the master key in a form that can be deciphered (or read) only by my program.
other things
there is an option for the user to change the master key.
The master key will be read and deciphered only once. At the start of the program. It will be stored in a variable then and and used from this variable.
It is a GUI application. And I am using python Tkinter.
details
Please note that the data is stored using another encryption that is not un breakable but enough for this kind of information.
I have not used any database to store the information.
The only data to be encrypted is a master key. It is an alphanumeric string of length anywhere from 7 to 80 characters.

In a couple of words, pip started to prompt for a user/password, which was quickly a pain (all automated tools were hanging forever...). And since today, it simply fails.
I was wondering how to have something more reliable. As I guess anyone can remove a package from pypi, it is not safe to fully rely on it, right ? I was using a cache and thought that would be enough, but apparently it always try to connect to the internet to check the package existence.
What is recommanded here ? Should I download everything manually, and only refer to local path via the variable "dependency_links" in my setup.py ? Or is there something smarter ?

In my system, there are many plugins contributed by different people that may not know each other. If I allow them to define their error codes. It's mostly like error code of two plugins may conflict.
================================================================================================
I want to design an extendable error codes system that allows plugins to define their own error codes.
The basic idea is:
system has a range of reserved error codes
plugin can select a range that not used by system, then creates its error codes in that range. However, the problem is plugins don't know each other(because plugins may be written by different people and installed into system by user's preference). so their error codes range may conflict.
Is there any good practice for this requirement? I google a lot but to my surprise, there are very few articles talking about designing error codes in production software. Most posts are focus on exception vs error code.
And, is there any good pattern for showing error in product that user could figure out what's going on?

How to train the system?
Can the system consist of "sci-fi" and "others"?
The answer to 2 is yes. Having a 80% confidence threshold idea also makes sense, as long as you see with your data, features and algorithm that 80% is a good threshold. (If not, you may want to consider lowering it if not all sci-fi movies are being classified as sci-fi, or lowering it, if too many non-sci-fi movies are being categorized as sci-fi.)

The worker thread/process will keep running. Moreover, if there is no wait/sleep in the loop, it will hog the CPU. Other threads/process will get very little cpu, resulting your entire site on slow response.
Also, I don't think server will send any timeout error to client explicitly. If the TCP timeout is set, TCP connection will be closed.
Client may also have some timeout setting to get response, which may come into picture.
Avoiding such code is best way to avoid such code. You can also have some monitoring tool on server to look for CPU/memory usage and notify for abnormal activity so that you can take action. | 1 | 7 | 0 | 0 | Something that I just thought about:
Say I'm writing view code for my Django site, and I make a mistake and create an infinite loop.
Whenever someone would try to access the view, the worker assigned to the request (be it a Gevent worker or a Python thread) would stay in a loop indefinitely.
If I understand correctly, the server would send a timeout error to the client after 30 seconds. But what will happen with the Python worker? Will it keep on working indefinitely? That sounds dangerous!
Imagine I've got a server in which I've allocated 10 workers. I let it run and at some point, a client tries to access the view with the infinite loop. A worker will be assigned to it, and will be effectively dead until the next server restart. The dangerous thing is that at first I wouldn't notice it, because the site would just be imperceptibly slower, having 9 workers instead of 10. But then it might happen again and again throughout a long span of time, maybe months. The site would just get progressively slower, until eventually it would be really slow with just one worker.
A server restart would solve the problem, but I'd hate to have my site's functionality depend on server restarts.
Is this a real problem that happens? Is there a way to avoid it?
Update: I'd also really appreciate a way to take a stacktrace of the thread/worker that's stuck in an infinite loop, so I could have that emailed to me so I'll be aware of the problem. (I don't know how to do this because there is no exception being raised.)
Update to people saying things to the effect of "Avoid writing code that has infinite loops": In case it wasn't obvious, I do not spend my free time intentionally putting infinite loops into my code.

When your game gets more complicated, it's easier if you use the technique ecline6 suggested:
changing your background image.
But since it is a loaded image i suppose, you can use this trick:
Let's say you have a background surface. Every 10s you will fire an event that will change the backround by blitting an low alpha-black surface on top of it. That way your background will get darker.

And, if you could, you would not want to store it.
In fact, the OS doesn't even have the user's password. The OS has a hash of it, and when the user logs in, it hashes what the user types and checks that it matches.
Also, if you ask the user to log in with their system password, any savvy user is going to immediately mistrust your app and refuse to use it. Make them create a password, and then login with that, not their system password. And don't save the password, save a hash, just like the OS does.
If you want to verify that they've been authenticated by the OS… well, you already know that, or they couldn't have logged in to run your app. (If you're building a network server that allows remote login based on local accounts, that's a different story, but it's not relevant to your use case, and complicated, so I won't get into it here.)
If you want to allow someone to "stay logged in", you don't do that by saving their password. Instead, you create some kind of hard-to-fake "session key" when they log in, and store that somewhere. They don't have to log in again until you destroy the session key (which you do when they log out).
The one exception to "never store passwords" is when you need to act as a "proxy" for the user to some other application that needs their password. A well-designed application will provide a way for you to proxy the login properly, but many applications are not well-designed. Web browsers have to do this all the time, which is why most web browsers have a "remember my password at this site" checkbox.
In this case, you do want to store passwords, ideally encrypted by the OS on your behalf (e.g., using OS X's Keychain APIs), or, if not, encrypted by you code using some key that's generated from the user's "master password" (which you don't store).
Unfortunately, there is no real shortcut to learning how to design for security—or, rather, there are all kinds of shortcuts, and taking any one of them means your entire system ends up insecure and all the work you put into trying to secure it ends up useless.
The easy solution is to use complete off-the-shelf solutions.
If you want to design things yourself, you need at least a basic grounding in all of the issues. Start with one of Bruce Scheneier's "pop" books, Secrets and Lies or Beyond Fear. Then read his Practical Cryptography on designing cryptosystems, and Applied Cryptography on evaluating crypto algorithms. Then, once you realize how much you don't know and how important it is, learn everything you need for your problem, and then you can think about solving it. | 2 | 1 | 0 | 0 | basically, I want to have a login box, and the option to remember the password next time you log in.

In that case, don't give the user a false sense of security, use cleartext.
A notable exception is the GNOME login keyring (and equivalent on other platforms) not asking for a password, but it uses a trick: it encrypts data with your login password and decrypts them with the same when you enter it at startup.
