1 | 1 | 0 | 2 | 1 | 1 | 1.2 | 0 | I was wanting to use some non-standard python packages in my project and was wondering how to add them. What is the benefit of using the AWS eb config files (.ebextensions and requirements.txt) rather than just downloading and including the package in my actual project under a lib directory like you would with a java application? | 0 | python,amazon-web-services,amazon-elastic-beanstalk | 2013-12-16T07:31:00.000 | 0 | 20,605,544 | by including it in the requirements.txt, you can include only the packages you are calling. Pip then takes care of installing the dependencies and checking the versions.
This has the additional advantage of when you are changing or upgrading your project, you can specify a new version of the library you are using and all the dependent libraries will also be updated. | 0 | 289 | true | 0 | 1 | Adding external packages to elastic beanstalk python app | 20,607,574 |
1 | 1 | 0 | 1 | 0 | 0 | 1.2 | 0 | My application polls an API repeatedly and spawns processes to parse any new data resulting from these calls, conditionally making an API request based on those data. The speed of that turnaround time is critical.
A large bottleneck seems to be related to the setup of the actual spawned processes themselves -- a few module imports and normal instantiation code, which take up to 0.05 seconds on a middling Amazon setup†. It seems like what it would be helpful to have a batch of processes with those imports/init code already done††, waiting to process results. What is the best approach to create/communicate with a pool (10-20?) of warm, reusable, and extremely lightweight processes in Python?
† - yes, I know throwing better hardware at the problem will help, and I'll do that too.
†† - yes, I know doing less will help, and I'm working on making the code as streamlined and minimal as possible | 0 | python | 2013-12-16T17:48:00.000 | 0 | 20,617,337 | Well, you're in for a learning curve here, but multiprocessing.Pool() will create a pool of any number of processes you specify. Use the initializer= argument to specify a function each process will run at the start. Then there are several methods you can use to submit work items to the processes in the pool - read the docs, play with it, and ask questions if you get stuck.
One caution: "extremely lightweight processes" is impossible. By definition, processes are "heavy". "How heavy" is up to your operating system, and has approximately nothing to do with the programming language you use. If you're looking for lightweight, you're looking for threads. | 0 | 442 | true | 0 | 1 | Pool of warm, reusable Python processes | 20,617,564 |
1 | 3 | 0 | 3 | 4 | 1 | 1.2 | 0 | This might be a more broad question, and more related to understanding Python's nature and probably good programming practices in general.
I have a file, called util.py. It has a lot of different small functions I've collected over the past few months that are useful when doing various machine learning tasks.
My thinking is this: I'd like to continue adding important functions to this script as I go. As so, I will want to use import util.py often, now and in the future, in many unrelated projects.
But Python seems to feel like I should only be able to access the code in this file if it lives in my current directly, even if the functions in this file are useful for scripts in different directories. I sense some reason behind the way that works that I don't fully grasp; to me, it seems like I'll be forced to make unnecessary copies often.
If I should have to create a new copy of util.py every time I'm working from within a new directory, on a different project, it won't be long until I have many different version / iterations of this file, scattered all over my hard drive, in various states. I don't desire this degree of modularity in my programming -- for the sake of simplicity, repeatability, and clarity, I want only one file in only one location, accessible to many projects.
The question in a nutshell: What is the argument for Python to seemingly frown on importing from different directories? | 0 | python,data-structures,import | 2013-12-17T01:18:00.000 | 0 | 20,624,211 | If your util.py file contains functions you're using in a lot of different projects, then it's actually a library, and you should package it as such so you can install it in any Python environment with a single line (python setup.py install), and update it if required (Python's packaging ecosystem has several features to track and update library versions).
An added benefit is that right now, if you're doing what the other answers suggested, you have to remember to manually have put util.py in your PYTHONPATH (the "dirty" way). If you try to run one of your programs and you haven't done that, you'll get a cryptic ImportError that doesn't explain much: is it a missing dependency? A typo in the program?
Now think about what happens if someone other than you tries to run the program(s) and gets those error messages.
If you have a library, on the other hand, trying to set up your program will either complain in clear, understandable language that the library is missing or out of date, or (if you've taken the appropriate steps) automatically download and install it so things are ready to roll.
On a related topic, having a file/module/namespace called "util" is a sign of bad design. What are these utilities for? It's the programming equivalent of a "miscellaneous" folder: eventually, everything will end up in it and you'll have no way to know what it contains other than opening it and reading it all. | 0 | 83 | true | 0 | 1 | What is the argument for Python to seemingly frown on importing from different directories? | 20,624,583 |

1 | 1 | 1 | 4 | 2 | 0 | 1.2 | 0 | I am using Google Protobuf in my Python application. Experimenting with the protobufs I found that Protobuf Message Creation is much slower in CPP based python implementation as compared to Python based Python implementation.
Message creation with PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=cpp was upto 2-3 times slower as compared to pure python based Protobuf Message Creation.
Is this expected? I found that SerializeToString and ParseFromString both are faster in the cpp verison. The difference in each case widens as the size of the Message increases.
I am using python's standard timeit module to time these tasks.

The pure-Python implementation stores all the fields in a dict. To construct a new message, it essentially just creates an empty dict, which is very fast. The C++ implementation actually initializes a C++ DynamicMessage object under the hood and then wraps it. DynamicMessage actually initializes all of the fields upfront, so even though it's implemented in C++, it's "slower" -- but this upfront initialization makes later operations faster.
I believe you can improve performance further by compiling C++ versions of your protobuf objects and loading them in as another extension. If I recall correctly, the C++-backed Python protobuf implementation will then automatically used the compiled versions rather than DynamicMessage. | 0 | 4,148 | true | 0 | 1 | Performance of C++ based python implementation of Google Protobuf | 20,713,817 |

I need to execute a bash shell command when a properly constructed email is received (I'm using GMail) using Python. I have previously used Python to send emails, but the only solution I have yet found is to use feedparser and Google Atom, which I don't like.

3 | 3 | 0 | 4 | 9 | 0 | 0.26052 | 0 | I am using py.test (version 2.4, on Windows 7) with xdist to run a number of numerical regression and interface tests for a C++ library that provides a Python interface through a C module.
The number of tests has grown to ~2,000 over time, but we are running into some memory issues now. Whether using xdist or not, the memory usage of the python process running the tests seems to be ever increasing.
In single-process mode we have even seen a few issues of bad allocation errors, whereas with xdist total memory usage may bring down the OS (8 processes, each using >1GB towards the end).
Is this expected behaviour? Or did somebody else experience the same issue when using py.test for a large number of tests? Is there something I can do in tearDown(Class) to reduce the memory usage over time?
At the moment I cannot exclude the possibility of the problem lying somewhere inside the C/C++ code, but when running some long-running program using that code through the Python interface outside of py.test, I do see relatively constant memory usage over time. I also do not see any excessive memory usage when using nose instead of py.test (we are using py.test as we need junit-xml reporting to work with multiple processes) | 0 | python,pytest | 2014-01-03T09:26:00.000 | 0 | 20,900,380 | py.test's memory usage will grow with the number of tests. Each test is collected before they are executed and for each test run a test report is stored in memory, which will be much larger for failures, so that all the information can be reported at the end. So to some extend this is expected and normal.
However I have no hard numbers and have never closely investigated this. We did run out of memory on some CI hosts ourselves before but just gave them more memory to solve it instead of investigating. Currently our CI hosts have 2G of mem and run about 3500 tests in one test run, it would probably work on half of that but might involve more swapping. Pypy is also a project that manages to run a huge test suite with py.test so this should certainly be possible.
If you suspect the C code to leak memory I recommend building a (small) test script which just tests the extension module API (with or without py.test) and invoke that in an infinite loop while gathering memory stats after every loop.

On the other hand, most dynamically generated web pages in PHP, Python, Ruby, etc. use templates that are static and there's just a small portion of dynamic content.

Content that is static for a user's entire session, such as a static top bar that's shown on each and every page (e.g. top bar on a site like Facebook that may contain a user's picture and name). Can this user specific information be cached locally in Javascript to prevent needing to request this same information for each and every page load?
Pages that are 99% static and that contain 1% of dynamic content that is mostly unique for a given viewer and differs from page to page (e.g. a page that only differs by indicating whether the user 'likes' some of the content on the page via a thumbs up icon.

The problem I've encounter at this point is that it is starting to be slow, thus, my system is not working properly, some processeses hang because SQS closes the connection and also writing to remotes machines.

My questions are:
What alternatives exist to SQS, I know of Redis, RabbittMQ, but both need local deployment, configuration and that might lead to unreliable functionality, if for example the box that is running it suddenly crashes and other boxes are not able to write messages to the queue.

That depends on the camera model, but since you mention in your post you are using "webcams", then the answer is almost certainly no. You could slow down the requests you make to the camera to take a picture though.
This sequence of events is possible:
wait
request camera takes picture
camera returns picture as normal
wait
This sequence of events is not possible (with webcams at least)
wait
request camera takes picture
wait
camera returns picture at a significantly later time that you want
to have control over

You might be able to find some other solution to your problem (for instance what happens if you request 50 photos from 50 cameras nd saturate the USB bus?

1 | 2 | 0 | 3 | 1 | 0 | 1.2 | 0 | We have a database that contains personally-identifying information (PII) that needs to be encrypted.
From the Python side, I can use PyCrypto to encrypt data using AES-256 and a variable salt; this results in a Base64 encoded string.
From the PostgreSQL side, I can use the PgCrypto functions to encrypt data in the same way, but this results in a bytea value.
For the life of me, I can't find a way to convert between these two, or to make a comparison between the two so that I can do a query on the encrypted data. Any suggestions/ideas?
Note: yes, I realize that I could do all the encryption/decryption on the database side, but my goal is to ensure that any data transmitted between the application and the database still does not contain any of the PII, as it could, in theory, be vulnerable to interception, or visible via logging. | 1 | python,postgresql,encryption | 2014-01-14T20:01:00.000 | 0 | 21,122,847 | Imagine you have a Social Security Number field in your table. Users must be able to query for a particular SSN when needed. The SSN, obviously, needs to be encrypted. I can encrypt it from the Python side and save it to the database, but then in order for it to be searchable, I would have to use the same salt for every record so that I can incorporate the encrypted value as part of my WHERE clause, and that just leaves us vulnerable. I can encrypt/decrypt on the database side, but in that case, I'm sending the SSN in plain-text whenever I'm querying, which is also bad.
The usual solution to this kind of issue is to store a partial value, hashed unsalted or with a fixed salt, alongside the randomly salted full value. You index the hashed partial value and search on that. You'll get false-positive matches, but still significantly benefit from DB-side indexed searching. You can fetch all the matches and, application-side, discard the false positives.
Querying encrypted data is all about compromises between security and performance. There's no magic answer that'll let you send a hashed value to the server and have it compare it to a bunch of randomly salted and hashed values for a match. In fact, that's exactly why we salt our hashes - to prevent that from working, because that's also pretty much what an attacker does when trying to brute-force.
So. Compromise. Either live with sending the SSNs as plaintext (over SSL) for comparison to salted & hashed stored values, knowing that it still greatly reduces exposure because the whole lot can't be dumped at once. Or index a partial value and search on that.
Do be aware that another problem with sending values unhashed is that they can appear in the server error logs. Even if you don't have log_statement = all, they may still appear if there's an error, like query cancellation or a deadlock break. Sending the values as query parameters reduces the number of places they can appear in the logs, but is far from foolproof. So if you send values in the clear you've got to treat your logs as security critical. Fun! | 0 | 2,355 | true | 0 | 1 | Encryption using Python and PostgreSQL | 21,128,178 |

1 | 2 | 0 | -1 | 4 | 0 | -0.099668 | 0 | Preface: I am fully aware that this could be illegal if not on a test machine. I am doing this as a learning exercise for learning python for security and penetration testing. This will ONLY be done on a linux machine that I own and have full control over.
I am learning python as my first scripting language hopefully for use down the line in a security position. Upon asking for ideas of scripts to help teach myself, someone suggested that I create one for user enumeration.The idea is simple, cat out the user names from /etc/passwd from an account that does NOT have sudo privileges and try to 'su' into those accounts using the one password that I have. A reverse brute force of sorts, instead of a single user with a list of passwords, Im using a single password with a list of users.
My issue is that no matter how I have approached this, the script hangs or stops at the "Password: " prompt. I have tried multiple methods, from using os.system and echoing the password in, passing it as a variable, and using the pexpect module. Nothing seems to be working.
When I Google it, all of the recommendations point to using sudo, which in this scenario, isnt a valid option as the user I have access to, doesnt have sudo privileges.
I am beyond desperate on this, just to finish the challenge. I have asked on reddit, in IRC and all of my programming wizard friends, and beyond echo "password" |sudo -S su, which cant work because the user is not in the sudoers file, I am coming up short. When I try the same thing with just echo "password"| su I get su: must be run from a terminal. This is at a # and $ prompt.
Is this even possible? | 0 | python,linux,security | 2014-01-17T06:29:00.000 | 1 | 21,179,274 | If you just want to do this for learning, you can easily build a fake environment with your own faked passwd-file.

You should make sure all other variables are as you expect them to be and test your single method. To do that for methods which use third party APIs, you should probably mock them using a mocking library. By mocking you provide data you expect and verify that your method works as expected. You can also try to separate your code so that the part which makes API request and the part that parses/uses it are separate and unit test that second part with a certain API example response you provide. | 0 | 569 | false | 0 | 1 | Python - unit testing | 21,203,787 |

As for unit testing, you have probably written your crawler with several components, like page parser, url recogniser, fetcher, redirect handler, etc. These are your UNITS. You should unit tests each of them, or at least those with at least slightly complicated logic, where you can expect some output for some input. Remember, that sometimes you'll test behaviour, not input/output, and this is where mocks and stubs may come handy.
As for functional testing - you'll need to create some test scenarios, like webpage with links to other webpages that you'll create, and set them up on some server. Then you'll need to perform crawling on webpages YOU created, and check whether your crawler is behaving as expected (you should know what to expect, because you;ll be creating those pages).
Also, sometimes it is good to perform integration tests between unit and functional testing. If you have some components working together (for example fetcher using redirect handler) it is good to check whether those two work together as expected (for example, you may create resource on your own server, that when fetched will return redirect HTTP code, and check whether it is handled as expected).
So, in the end:
create unit tests for components creating your app, to see if you haven't made simple mistake
create integration tests for co-working components, to see if you glued everything together just fine
create functional tests, to be sure that your app will work as expected (because some errors may come from project, not from implementation) | 0 | 569 | true | 0 | 1 | Python - unit testing | 21,203,798 |

We haven't started the development, but we chose python for various reasons. So I don't wanna switch to PHP just because of an api-sdk.
Here are my thoughts for a possible solution:
Rewrite the api-sdk in Python. It's not extremely complex. I guess it will take 3-5 days. However we have to update the sdk by ourself. And the api, for what the sdk is made for, changes a lot.
Write a wrapper around the sdk. That enables us to call each single sdk-function by executing a php file in python like execfile(filename).
Or I use a wrapper to make the sdk-functions accessible via url.
The sdk returns result objects (like productResult).
The problem with solution 2 and 3 is that I can't to use these result objects in python. Solution 2 & 3 have to return a JSON. So I would lose some functionality of the api.

not sure, if Heroku allows other than HTTP protocols. It shall try to connect to your application after it gets started to test, it is up and running. It is possible, the test will attempt to do some HTTP request which is likely to fail with ZeroRPC service.
what about authentication of users? You would have to build some security into ZeroRPC itself or accept providing the service publicly to anonymous clients.
Proposed steps:
try providing the ZeroRPC services on the port, Heroku provides you.

if you have changes in xml file of those module you have to update only those module.
if you going to update base module it will update all module which installed in your databae,
because every module depend on base, we can call base is the kernal of our all modules, all module depend on this module, if you update base it will going to update all modules
if you have done some changes in sale then you have to search for sale and update the only
sale module not go to update base module

Note: I have Messaging,Sales,Invoicing,Human-resource,Tools and Reporting modules installed,is it due to i have more modules installed??
Thanks in advance. | 0 | python-2.7,openerp,base | 2014-01-28T05:30:00.000 | 0 | 21,397,605 | As you have said that You are new to OpenERP, Let me tell you something which would be very helpful to you. i.e Never Do changes in Standard modules not in base. If you want to add or remove any functionality of any module, you can do this by creating a customzed module. in which inherit the object you want, and do the changes as per
your requirement.
Now regarding the time spent when upgrading base module, This is because when you update base module it will automatically update all the other modules which are already installed (in your case - Sales,Invoicing,Human-resource,Tools and Reporting) as base is the main module on which all the other modules are dependedent.
So, Better is to do your changes in customized module and upgrade that perticular module only, not the base.

Does the boto takes care of credential rotation? (For example, imagine I have an instance that should be up for a long time, and it constantly have to upload keys to s3 bucket. In case if credentials are expired, do I need to 'catch' an exception and reconnect? or boto will silently do this for me?)

I would hate to have to rewrite my code with absolute-imports every time I want to update mypackage in site-packages, and then change it back if I want to make changes and debug my code in Eclipse. | 0 | python,eclipse,pydev | 2014-02-05T01:58:00.000 | 0 | 21,567,271 | Adding the project directory /${PROJECT_DIR_NAME} to the project's PYTHONPATH seems to have done the trick.
Before, I only had /${PROJECT_DIR_NAME}/mypackage in the project's PYTHONPATH. So I suspect that, when using absolute imports, Eclipse was unable to find /${PROJECT_DIR_NAME}/mypackage/mypackage/mymodule and would then proceed to search in site-packages. | 0 | 638 | true | 0 | 1 | PyDev imports from package in site-packages rather than package in development (absolute-imports) | 21,666,549 |

1 | 2 | 0 | 0 | 2 | 0 | 0 | 0 | I'm new to Emacs and I'm trying to set up my python environment. So far I've learned that using "python-mode.el" in a python buffer C-c C-c loads the contents of the current buffer into an interactive python shell, apparently using what which python yields. In my case that is python 3.3.3. But since I need to get a python 2.7 shell, I'm trying to get Emacs to spawn such a shell on C-c C-c. Unfortunatly I can't figure out, how to do this. Setting py-shell-name to what which python2.7 yields (i.e. /usr/bin/python2.7) does not work. How can get Emacs to do this, or how can I trace back what Emacs executes when I hit C-c C-c? | 0 | python,python-2.7,emacs,emacs24 | 2014-02-05T21:03:00.000 | 1 | 21,588,464 | I don't use python, but from the source to python-mode, I think you should look into customizing the variable python-python-command - It seems to default to the first path command matching "python"; perhaps you can supply it with a custom path? | 0 | 1,019 | false | 0 | 1 | Using python2.7 with Emacs 24.3 and python-mode.el | 21,590,370 |
1 | 1 | 0 | 0 | 1 | 0 | 0 | 0 | I have developed couple of extensions and never had any problem in deploying to the production server. I did try to installation a new extension today on my production server that works on my dev machine but doesn't work on the production server. I am suppose to see a new menu option as part on this new extension and I don't see that. To test I changed the extension name in the production.ini and I got an expected error (PlugInNotFoundError). I have restarted the apache and nginx. I am running CKAN 2.1.
I did ran the following command on the production server:
python setup.py develop
I got the message that the plugin was successfully installed.
I also included this new plugin in the production.ini file settings.
Restarted both the apache2 and nginx servers.
Still not seeing a new menu option to access the functionality provided by this newly installed extension.
Any help to sort this out be appreciated.
Thanks,

1 | 2 | 0 | 0 | 0 | 0 | 0 | 1 | Im working on a little project that running rabbitmq with python, I need a way to access the management api and pull stats, jobs, etc. I have tried using pyRabbit, but doen't appear to be working unsure why, hoping better programmers might know? Below I was just following the basic tutorial and readme to perform the very basic task. My server is up, I'm able to connect outside of python and pyrabbit fine. I have installed off the dependencies with no luck, at least I think. Also open to other suggestions for just getting queue size, queues, active clients etc outside of pyRabbit.
