I want to Search for an Object name. If i have this Structure: /de/myspace/media/justAnotherPdf.pdf Then i want to Search for the name "justAnotherPdf" to find it or something like "justAnot" I have Indexed the pdf files. But i cant search it with TextIndexNG2 or PathIndex.

Currently this is not supported out-of-the-box. Object identifiers (getId) are only indexed as field values and thus can only be looked up as whole strings. You'd need to add separate index to the catalog to support your use-case. You could add a new TextIndexNG2 index with a new name indexing just the getId method. In the ZMI, find the portal_catalog, then it's 'Indexes' tab, then on the right-hand-side you'll find a drop-down menu for adding a new index. Pick a memorable name ('fullTextId' for example) and use getId as the indexed attribute. You'll need to do a reindex, but only for that index. Once added, select it in on the Indexes tab (tick the check-box) and select 'Reindex' at the bottom of that page. Now you can use this index in your custom searches with a wildcard search.

I have a C++ process running in the background that will be generating 'events' infrequently that a Python process running on the same box will need to pick up. The code on the C side needs to be as lightweight as possible. The Python side is read-only. The implementation must be cross-platform. The data being sent is very simple. What are my options? Thanks

How complex is your data? If it is simple I would serialize it as a string. If it was moderately complex I would use JSON. TCP is a good cross-platform IPC transport. Since you say that this IPC is rare the performance isn't very important, and TCP+JSON will be fine.

I will say you create a DLL that will manage the communication between the two. The python will load DLL and call method like getData() and the DLL will in turn communicate with process and get the data. That should not be hard. Also you can use XML file or SQLite database or any database to query data. The daemon will update DB and Python will keep querying. There might be a filed for indicating if the data in DB is already updated by daemon and then Python will query. Of course it depends on performance and accuracy factors!

Does anyone know, what is the actual reason behind "dollar variable notation" in some of the scripting languages, i.e. PHP or Perl? Python creators did not find $variable useful, neither do I. Why does PHP and Perl force me to press shift-4 so often? (OK, in Perl you can somehow explain it with distinguishing $scalar, @array and %hash but still it could be successfully avoided there, type does not need to be explicit)

With pyudev, each device object provides a dictionary-like interface for its attributes. You can list them all with device.keys(), e.g. UUID is for block devices is dev['ID_FS_UUID'].

I'd like some advice on how to check for the correctness of the parameters I receive. The checking is going to be done in C++, so if there's a good solution using Boost.Python (preferably) or the C API, please tell me about that. Otherwise, tell me what attributes the object should have to ensure that it meets the criteria. So... How do you check that an object is a function? How do you check that an object is a bound method? How do you check that an object is a class object? How do you check that a class object is a child of another class?

I have two unconventional recommendations for you: 1) Don't check. The Python culture is to simply use objects as you need to, and if it doesn't work, then an exception will occur. Checking ahead of time adds overhead, and potentially limits how people can use your code because you're checking more strictly than you need to. 2) Don't check in C++. When combining Python and C (or C++), I recommend only doing things in C++ that need to be done there. Everything else should be done in Python. So check your parameters in a Python wrapper function, and then call an unchecked C++ entry point.

When in doubt just work out how you would get the required effect by calling the usual Python builtins and translate it to C/C++. I'll just answer for Python, for C you would look up the global such as 'callable' and then call it like any other Python function. Why would you care about it being a function rather than any other sort of callable? If you want you can find out if it is callable by using the builtin callable(f) but of course that won't tell you which arguments you need to pass when calling it. The best thing here is usually just to call it and see what happens. isinstance(f, types.MethodType) but that won't help if it's a method of a builtin. Since there's no difference in how you call a function or a bound method you probably just want to check if it is callable as above. isinstance(someclass, type) Note that this will include builtin types. issubclass(someclass, baseclass)

I'm deciding on a web framework for an upcoming project, and I'd appreciate any advice. We've decided to use jQuery for the JavaScript, and are heavily leaning toward Python or PHP (more Python) for our server-side logic. I'm especially interested in web2py because of its jQuery integration. About our project Our project is to develop a security console for a complex cybersecurity system operating within an organization's internal network. This console will be largely server-driven, as messages come in from the network and must be pushed by the server to the user. The user will also be able to initiate security actions, the implementation for which will likely be in C++. The interface we've planned will be relatively rich, and I want to leverage jQuery's power as much as possible. We have some control over the browser environment we'll be running in (e.g., we don't have to worry about clients with JavaScript disabled). Our site is likely to have only a few, long-lived client connections. We are looking for software components with permissive licenses, though we're using some copyleft components (I see that web2py is LGPL while Django is BSD, so +1 to Django) We have about a month to create a functional demo of our system, of which this interface is a small (but visible) part. About us We are two developers with about 5 years of programming experience, but little web development experience. I have several years of Python experience and a summers' worth of experience messing around with PHP. My coworker has some Python experience and has never touched PHP. I used Django once back in 2008, and was frustrated by the file and code structure, which I found highly unintuitive. Perhaps this structure is inherent to the MVC model (I've had similar experiences with Django and CakePHP since), and I just need to bite the bullet and memorize it. My Question Given the information above, what are the relative advantages of the various Python/PHP web frameworks for our project? As mentioned above, I'm especially interested in web2py because of its jQuery integration, though Django's dominance is (once again) hard to ignore. Thank you very much for your time!

I've been using Django as part of my work for a couple years now and truly enjoy it when I can make it work. Unfortunately, and maybe it's just me, but I end up spending hours working on configuration every time I start a new server, or try to make it work in a development IDE. It's relatively simple to start a new project and start coding. But there are all sorts of little catches that keep things from working if you deviate from the norm. Things like if you want your django project to serve from a subdirectory like example.com/django. The information is out there to make it work. But it's hard to find. I can't tell you if web2py has those same problems or not. I only just learned about it from your question. It does look slick and simple though. I can tell you that after the hassles of getting the applications to serve properly from whatever server configuration I'm using, django is way more fun to program with than plain php. PHP frameworks may differ.

Python vs PHP: Python With python, you can always write wrappers for C code so you won't have to mess with starting other processes and passing args to them. That might be useful for your security functions. Web2py will allow you to easily write a webservice for this too, to more easily integrate the C portions with the web-site infrastructure. If you already prefer python, I would go with that. If you need to bring on web-developers later that are trained in PHP, teach them Python. It won't take long, and I'm sure they'll appreciate it in the long run. Plus, moving from a PHP MVC framework to web2py or even django would make things easier. I've used CodeIgniter for PHP and find that web2py was so much simpler and easy to understand. Also as for the directory structure, django is not actually true MVC -- it's MTV (model, template, view). I find web2py's organization a little more straight-forward. But yes, either way it can seem strange at first. I would say YES, you should bite the bullet and use MVC. In web2py, the "view" is html markup with the ability to write raw python code. The controller extracts data from the model (database), attaches any needed files (css/js etc) and the model of course simply defines the structure of the data and allows you to access it in an OO way. Lastly, I wouldn't tip my hat in favor of web2py just because of jQuery integration. It does use it, and a some of the built-in framework stuff (like response.flash/session.flash, the LOAD function that loads a page or data from another controller) rely on jQuery, but using it in another framework only means you have to write an include statement (e.g. ). But, the way it allows/forces you to focus on development is what takes the cake for me.

Before deciding on a framework, you should first decide if you want to commit to a language you are unfamiliar with. You said you've both got minimal PHP experience, so you have to weigh up the advantages here; Will the pros for going PHP (if any) out weigh the amount of time the developers will need to spend to retrain? (Although depending on your background experience, PHP should be very easy to pick up.) If you frame it like that, PHP would have to have a pretty convincing offering to give you. From what I'm seeing, specifically Django vs web2py, they both seem very close in functionality - which is good, but doesn't provide the "you must use x!" scenario you may be after. However, If you will be bringing more people in later and feel finding people to work with web2py will be difficult, it may tip it to PHP. You said your self, Django's popularity (and BSD license) is hard to ignore, and it should make it easier to find people for later expansion. If it were me, in your shoes, I would go with web2py. Assuming the development team will continue to be Python focused for the foreseeable future.

You have no other way than generate confirm url in your message like most sites registrations do. If person would be glad to register on your website, he will certainly click confirm at his email client of any sort. Otherwise it's a spam/scam email. There is no way you can do it and know it's a live e-mail for sure... Besides there are 2 other ways mentioned by my colleagues... But they are based on "unsecure" settings in old email clients rather than sure way... IMHO.

You can try setting require return receipt flag on the email you are sending. But, a lot of people (I know I do) ignore that return receipt so you will never find out in those cases. If you are asking for a 100% certain method of finding out if the recipient read his/her email, then the straight answer is: NO, you can't do that.

I'm currently researching deployment techniques for our Python products. We manage our code with multiple git repositories already but want to improve the process of setting up and updating our servers. It seems that easy_install, .egg files and virtualenv are the best tools for doing this nowadays. Here's the catch: We don't really do versioning; all our products have a master branch which is supposed to provide stable code all the time. If we want to update, we have to git pull the master branch on every server, for each product and all its dependencies. This solution is very time-consuming and we want to improve it. My idea was to create a virtualenv instance on all servers/installations and use easy_install to install and update our own packages, but I couldn't find a way to specify a git repository as a source for the source code. Is there a way to achieve that? Did I miss something? Am I going in the wrong direction and this is a bad idea overall? Thanks in advance, Fabian

I have several scripts written in perl, python, and java (wrapped under java GUI with system calls to perl & python). And I have many not-tech-savy users that need to use this in their windows machines (xp & 7). To avoid users from installing perl,python,and java and to avoid potential incompatibility between various versions of these interpreters, I'd like to make a local copy of these interpreters in a folder and then calling them. I'd zip the whole folder (which would also contain my code) and send it away. I'd have to worry about environment variables and make calls to the correct interpreter (especially when other versions of python,java,perl may exists in their current system), but not sure what other problems I may face. Any better ideas? I never used jython and do not know the overhead of moving to it. I also suspect a complex python system, with many files and 3rd party modules will have problems. Same with perl scripts and I don't know a robust perl interpreter callable from java. Thank you, in advance.

Why don't you try migrating your perl/python code into java and then packagin everything into a nice webstart application? What do perl/python offer that java doesn't support? For perl you can use something like perl2exe and for python py2exe so you can have 2 exes (which would include all the necessary interpreter bits) and invoke them as resources from within java? Or unzip them inside user's home directory and call them again as normal external programs (ProcessBuilder ?) ?

I'm trying to get certain strings in a .py file translated, using the i18n machinery. Translating .pt files is not a problem, but whenever I try to translate using _('Something') in Python code on the filesystem, it always gives English text (which is the default) instead of the Norwegian text that should be there. So I can see output from python code in English, while other Page Templates bits are correctly translated. Is there a how-to or something similar for this?

be aware that _() does not translate the text at call, but returns a Message object which will be translated when rendered in a template. That means: do not concat Message objects. "text %s" % _('translation') will not work, as well as "text" + _('translation') if you do not send the text to the browser through a template, it may not be translated. for example if you generate a email you need to translate the Message object manually

You don't need a tool to create a python module, any filename ending in .py is sufficient. A package, which is a collection of modules, is similarly created by the presence of a file named __init__.py in the same folder as other modules (and possibly other packages). The __init__.py file can be empty or not, your choice. Best practices dictate that importing a module should have no side effects; It should define classes and functions, but take no action. python modules should start with a docstring explaining the purpose of the module and how it should be used.

I am having a python .so file which works fine with python v2.4.3 , but I dont have the source code of that library file. Now It fails to work in python 2.6.5. Is it possible to open the .so file and recompile it in python 2.6.5 ?? I dont know whether it is possible, I am just curious . Thanks !

A .so file (.pyd on Windows) is a module which was written in C. It's compiled for, and tied to, a specific version of Python, in this case Python 2.4.x. If you want it to work with a different version of Python, you'll need to re-compile the original source code for that version.

I am about to get involved in a NLP-related project and I need to use various libraries. Some are in java, others in C/C++ (for tasks that require more speed) and finally some are in Python. I was thinking of using Python as the "glue" and create wrapper-classes for every task that I want to do that relies on a different language. In order to do that, the wrapper class, for example, would execute the java program and communicate with it using pipes. My questions are: Do you think that would work for cpu-demanding and highly repetitive tasks? Or would the overhead added by the pipe-communication be too heavy? Is there any other (preferably simple) architecture that you would suggest?

I would simply advise not doing this. Don't implement stuff in C/C++ "for speed". The performance benefit is not likely to be as great as you expect; e.g. compared with implementing in Java using "best practice" design and performance techniques. Don't try and glue lots of languages together. You are setting yourself up for lots of portability issues, difficulties in debugging, and reliability issues; e.g. due to C / C++ bugs crashing the JVM. In addition, there are performance overheads in bridging between languages, and there can be unexpected bottlenecks. (For instance, you may find that your C/C++ has to be run single-threaded due to threading issues, and that you therefore can't get the benefit of Java multi-threading on a typically multi-core system.) Instead, I advise you to look for libraries that allow you to implement the entire application in one language. If that is not possible, design it so that the different language components are different executables / processes, communicating via some kind of RPC, messaging, or whatever.

This is simply a personal exercise/project, I don't intend to inflict this on the world. My goal is to further my understanding of both languages, and it would be a nice having a nice Python code base in the end. But basically there is a program I like with a large (about 100ksloc) C++ code base, what I'd like to do is gradually rewrite modules in Python while having the existing C++ code use the new Python. The reason I'd like to do it this way instead of starting from scratch is because the application would/should be fully functional from the beginning. Prime question is: Is this realistic? I'm pretty sure it'd work in theory, but in practice is it just not worth the effort? Has anyone done it before?

having the existing C++ code use the new Python I think you'll find that python makes a better glue language for C++ than C++ does for python. So you probably will have an easier time converting the main function to python first (in fact, the first step could be just renaming the main function, compiling the C++ app as a python library, and having one line of python which calls the renamed main). Then start moving functionality from C++ to python one line at a time. As @freedompeace suggested, you may want to leave significant chunks in C++, with python providing the glue. Depends on whether portability or speed/memory efficiency is more important to you.

I usually unit test per class and this is no problem. However after messing around with python I have hit a problem that I have not encountered before in other languages, meta classes and inner classes. Say I have a class that contains an inner class and also has a meta class, what is the best way to structure unit tests for this situation? One way could be to test all three in a single test module as they are so tightly coupled anyway. But this seems wrong to me. But how would I unit test the meta class on it's own, create a dummy class within the test that uses said meta class?? Your thoughts please stackoverflow!

You test a class by instantiating it. The "dummy class" you mentioned would be an instance of the metaclass, so that's exactly how you should test it. When it comes to testing the inner class / outer class -- yes, I would include testing the inner class in the test for the outer class. If it makes sense to test the inner class independently from the outer class, why is it an inner class at all? Any inner class should only make sense in the scope of the outer class. If you are going to test it independently, you'll have to imitate the environment of the outer class anyway.

I'm in the process of setting up a webserver from scratch, mainly for writing webapps with Python. On looking at alternatives to Apache+mod_wsgi, it appears that pypy plays very nicely indeed with pretty much everything I intend to use for my own apps. Not really having had a chance to play with PyPy properly, I feel this is a great opportunity to get to use it, since I don't need the server to be bulletproof. However, there are some PHP apps that I would like to run on the webserver for administrative purposes (PHPPgAdmin, for example). Is there an elegant solution that allows me to use PyPy within a PHP-compatible webserver like Apache? Or am I going to have to run CherryPy/Paste or one of the other WSGI servers, with Apache and mod_wsgi on a separate port to provide administrative services?

You could do this - Use Javascript to check progress every 3 seconds. Your Python script hit at anytime should give the progress at that instance. It should essentially act as state-machine. You need a server here or maybe the progress is stored on some file. But having a server is the way to go... Maybe the long running process stores the progress in a MySQL table. Hope this helps...

You mean you're using the "log in via twitter" hack? Well, if you want a "remember me" option you can build one just like normal (store some session info in a cookie... all security caveats apply). If the actually are logged out and there's no cookie then you have to go through the whole process again anyway. The authorize step will just redirect them right back, likely, since they have already authorized your app.

I've noticed how easy it is to debug a Python script from Eclipse. Simply set breakpoints and run a Python script from the debug menu. But is it possible to start a Python Interactive Interpreter instead of running a particular Python script, whilst still having Eclipse breaking on breakpoints? This would make it so much easier to test functions. Thanks for any help Still looking for a simple/ish way to start the debugger in Eclipse->PyDev that lets me use the interactive debugger.

what about this, in the script, you can write a function, say onlyForTest, then each time you write a new function and want to test it, you can just put it in the onlyForTest function, then specify some arguments required by the new function you just write, then open the interactive python shell, import the script, call the onlyForTest function, check out the result.

I'm primarily using Drupal and am considering moving away from CMS. If I were to build my own platform could I integrate modules like commenting systems, user login, etc. through a PHP/Python API? What would be the proper steps/good places to look/good tutorial on this? Would I have to build all of my own tables manually to suit the needs of such custom modules? I'm wondering if this would even be possible with out having to hard code all of this by hand? Thank you.

First of all if you are considering moving away from CMS than you should consider using some sort of framework but with time you will come to idea that you need your own shit in order to be satisfied. Second, subject you are trying to decipher is a little bit more complex than just writing it down here. I would suggest you to first think what do you need. What is your main goal with it or what are you trying to accomplish? For example in meaning of commenting, if you want the truth nor PHP nor Python are masterpieces. Why not to consider Node.JS for that? I mean, web is becoming real-time more and more. Now days we have scripts or to be more precise, pieces of art such as Socket.IO who can with help of Node.JS handle large amount of traffic without any problem. Something nor Python nor PHP can do. Some stuff you will need to code by yourself but most of the time you just need to code "architecture link" between one versus many features. Eg. take some code and adjust it to be able use it from your own framework or whatever. As far I see it. I like to do all crucial parts by myself but for example there is Zend Framework and you can use ACL + Auth library and start from there. Hope this makes some sense. Cheers!

I'm unit-testing a python c module in Eclipse using PyDev unit-testing. The development steps are: I first write the python tests in Eclipse and then the c code that passes the tests for the module in Codeblocks. Here is where a script is called to create a dll and ctypes bindings for it. After that the “dll” and the “py” code is copied to a directory where the module can be easily imported. But sometimes I get the error: IOError: [Errno 13] Permission denied: 'C:\...\pyCModule.dll' I’ve haven’t found the reason for that (deactivating code analysis and code completion haven’t helped). I’ve checked with the Process Explorer (from sysinternals) and it shows that the eclipse process has python.exe as child (I suppose that’s from PyDev) and that one is using my pyCModule.dll (and not always releasing it). Does someone have and idea of want could be done here? or what is wrong? Thanks in advance ! Francis

This happens because PyDev launches a shell that imports that dll (to do code-completion). You can do Ctrl+2 kill (with focus in a PyDev editor), to kill all the shells that PyDev may have spawned (that way you can update it). Cheers, Fabio

I just did this today and a far easier way to do it is to use the built-in installer. Go to Help -> Install New Software and then type pydev in the software filter. Since you already have the zip, if you extract it in the dropins folder, you'll skip the download portion and go straight to installing it. I have been able to use the zip to install it manually before. I would extract its contents in the eclipse folder overwriting the features and plugins folder. I suggested this to a coworker earlier today and it didn't work for her. She had to download the newest version of eclipse for this method to work. She downloaded the classic version.

Python honors PYTHONPATH environmental variable. It is a PATH like environmental variable specifying paths where Python loads modules. Inside .py script PYTHONPATH can be accessed and updated through the sys.path variable. If you can show more source code how you create Python interpreter more helpful answer can be given.

I'm implementing a profiler in an application and I'm a little flummoxed about how to implement Python profiling such that the results can be displayed in my existing tool. The application allows for Python scripting via communication with the python interpreter. I was wondering if anyone has ideas on how to profile Python functions from C++ Thank you for your suggestions :)

The usual technique for profiling already-existing functions that we use in Lua a lot is to overwrite the function with your own version that will start timing, call the original function, and stop timing, returning the value that the original function returned.

I am trying to import the OpenGL.GL module. Given the py file with that line, I can perform "python file.py" just fine, but I cannot run that same file when used in Aptana or Eclipse. Both IDEs have PyDev installed. I do have PyOpenGL installed. I wish to point out that I can still import other modules (PIL, numpy), which were installed the same way as the PyOpenGL. I am confident that there is only 1 python running on my MacOS.

Are you sure you don't have multiple versions of python? Seems to me like the interpreter that aptana uses is not the same as the one used from command line. You can look in: Run -> Run configurations -> Python run -- then you have Interpreter tab There you can click : See resulting command line. Than will get you the python that is used as well as the python path

I had the same problem after installing a different version of PyOpen and my Eclipse PyDev path is messed up. What I did was remove the interpreter link and re-added the old one which made PyDev to re-scan my libs. This seems to fix the problem. Don't forget for all your projects, you need to go to the property (Right click project->properties) and re-select the interpreter.

Is it possible to retrieve messages from an SQS queue during their visibility timeout if you don't have the message id? I.e. something along the lines of "get invisible messages" or "get messages currently being processed". I'm working with large timeouts and sometimes I'd like to be able to inspect the queue to see what's left. I'd rather not have to wait for a 5 hour timeout to expire. I'm working with boto in python. Thanks.

As far as I know there is no way of doing this. Seeing as your processing code should only take what it needs off the queue and nothing more it doesn't seem like you would ever need to do this. Do your jobs actually take 5hrs to complete? I assume based on "I'm working with large timeouts" they do but if not you can set the expiration to make it a shorter period.

First, props to whoever did node.js. I've been using it for less than a day and I'm already thinking about using it for stuff I use Python for now. In fact, whoever did node.js should think about using it for stuff they use Python for now. There is apparently a tool called node-waf that is in Python and is necessary for npm to work and npm of course is necessary for anything else useful. I think that my original install went bad because node-waf (which is in /mnt/michael/bin/node-waf) couldn't find Scripting.py (which is in /mnt/michael/node/tools/wafadmin/; it was looking in non-existent /mnt/michael/node/tools/../lib/node/wafadmin/). So I hacked node-waf to point to the right director and kept going and found a much more serious problem. Turns out node-waf isn't written in "Python", but in Python2.6, which is a perfectly good language, it's the language I use myself, but it isn't the language that the default on the system I use. The system is CentOS, which requires Python2.4 be the Python that the command "python" invokes. Yes, that's foolish on the part of the CentOS people but less foolish than the same mistake on the part of the node-waf people, since they are necessarily subject to the rules of the OS. So, please tell me there's some switch I haven't found yet that say "Use Python2.6". Also, any hints about a proper install would be appreciated.

To solve the path problem, I backed up and re-installed Node. To solve the version problem, at the suggestion of some bright soul on the #nodejs channel, I created a symbolic link at ~/bin/python that pointed to the right version (that solved a lot of my own problems too, starting up the wrong version from the command line...) An obvious hack, but when you're frustrated, you overlook the obvious.

Well Aptana is built upon eclipse, so you could just use the basic eclipse with all your necessary add ons. Obviously you'll need Pydev for the python stuff and that has Django integration. For some reason though I actually prefer netbeans for my php ide. Tbh just try out a few and see which one you like best.

I want to be able to identify an audio sample (that is provided by the user) in a audio file I've got (mp3). The mp3 file is a radio stream that I've kept for testing purposes, and I have the Pre-roll of the show. I want to identify it in the file and get the timestamp where it's playing in the file. Note: The solution can be in any of the following programming languages: Java, Python or C++. I don't know how to analyze the video file and any reference about this subject will help.

I'd start by computing the FFT spectrogram of both the haystack and needle files (so to speak). Then you could try and (fuzzily) match the spectrograms - if you format them as images, you could even use off-the-shelf algorithms for that. Not sure if that's the canonical or optimal way, but I feel like it should work.

I am looking for feasible solutions for my Application to be backed with MongoDB. I am looking to host the MongoDB on the cloud with a python based server to interact with the DB and my app (either mobile/web). I am trying to understand how the architecture should look like. Either i can host a mongoDB on the AWS cloud and have the server running there only. I also tried using MongoLab and seemed to be simple accessing it using HTTP requests. but i am not sure if it exposes all the essential features of MongoDB (what ever i can do using a pymongo driver)? Also, should i go for accessing the MongoLab service directly from my application or still i should build a server in-between? I would prefer to building an server in either case as i want to do some processing before sending the data back to application. but i am not sure in that case how my DB-server-app interaction design should be Any suggestions?

One thing to consider is that you don't need to use MongoLab's REST API. You can connect directly via a driver as well. So, if you need to implement business logic (which it sounds like you do), it makes sense to have a three tier architecture with an app server connecting to your MongoLab database via one of the drivers. In your case it sounds like this would be pymongo. -will

It does not really matter in which language you would make it. If you are good programmer, the application will work fine in any of those environment. If you are not good programmer, it will sux always :) you can do it for example in Ruby on Rails, but what is the purpose if you will not be able to follow MVC structure? it's a little bit risky to use technology that you do not know. There are many issues you can run into. Just for example N+1 queries. I wouldn't recommend you switching the language, unless you really would like to learn other technology - but be aware that your application most probably will not be "pretty" :)

I think you should stick with PHP : you already know the language you already have the tools for development you already have a code base I think you should see how your site behaves in production and see what are the most wanted user needs before spending time rewriting everything, and during this time not beeing able to answer correctly to their needs. And while your site sends its first bits, it will give you a lot more info on what to expect from the version 2, from a technical point of view. Edit : I am not pro-php, I just think you should stick whit the language you already know, until your business gives you time to learn something else.

I was wondering if there are any settings I need to do to enable Satchmo sending me an email (to the store config email address) each time an order is placed? I have set up the template: templates/shop/email/order_placed_notice.html and enabled Send HTML Email in the settings. The site is sending the order placed and order shipped emails to the customer no problems, but is not sending an email to the store email. I have searched through the Satchmo docs around the settings and couldn't find anything. Should I be changing something to the signals? I have gone through the signals.py, listeners.py and mail.py files and done reading on Django & Satchmo Signals but was reluctant to play around as my programming knowledge isn't too great.

I have a launchd entry that worked with OSX 10.6 but that fails with 10.7. It uses python, and it produces an error whilst trying to import serial. I don't quite understand this, because I've re-downloaded pyserial-2.5 and re-installed it with sudo. (In desperation, I re-installed it for each of the many flavours of python on my machine.) As a test, I can enter python and do import serial without difficulties. Maybe there is a system path that is set up well for an interactive user, that is not set up for launched?? Can anyone suggest how I might diagnose the problem?

The path you are appending: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages is the site-packages directory for a third-party, non-system Python, possibly installed using a python.org installer, and not that of the Apple-supplied system Python 2.7, which would be: /Library/Python/2.7/site-packages So most likely you are using the python.org Python to install pyserial but are launching the system Python under launchd. Check your shell PATH (echo $PATH), it probably has: /Library/Frameworks/Python.framework/Versions/2.7/bin in it. And try which python. If you want to use the python.org Python with your launchd plist, modify it to use an absolute path to the right Python, for instance: /Library/Frameworks/Python.framework/Versions/2.7/bin/python If you want to install pyserial with the system supplied Python, you can use an absolute path to it when doing the install: /usr/bin/python2.7

I am working with a pressure-sensing mattress having a USB interface. The maker provides USB device drivers for Windows, and an API written in C++ which has functions to request data and set some parameters. Currently, I cannot use this sensor for testing some Python data-visualization scripts directly, having had to ask my coworkers to write a text-logger for me, and then I read this information offline with Python. Also, I cannot use Linux at all with the sensor, because there are not drivers for Linux, and I do not know where to start to "hack" the sensor, and that is why I am asking: "If I were to try to read data from this sensor directly with Python and perhaps in Linux, what should I do first, or read first?" EDIT: the device has an FTDI driver (FTD2XX.dll) if it helps. Any help would be very welcome

I'm in the process of writing an application with an Urwid front-end and a MongoDB back-end in python. The ultimate goal is to be able to be able to serve the application over SSH. The application has its own authentication/identity system. I'm not concerned about the overhead of launching a new process for each user, the expected number of concurrent users is low. Since the client does not recall any state information and instead it is all stored in the DB I'm not concerned about sessions as such except for authentication purposes. I was wondering if there are any methods to serving the application as is without having to roll my own socket-server code or re-code the app using Twisted. I honestly don't know how Urwid and Twisted play together. I see that Urwid has a TwistedEventLoop method which purports to use the twisted reactor but I cannot find any example code running an Urwid application over a twisted connection. Examples would be appreciated, even simple ones. I've also looked at ZeroMQ but that seems even more inscrutable than Twisted. In short I explored a number of different libraries which purport to serve applications over tcp, most of them by telnet. And nearly all of them focusing on http. Worst case scenario I expect that I may create an extremely locked down user as a global login and use chrooted SSH sessions. that way each user gets their own chroot/process/client. Yes, I know that's probably a "Very Bad Idea(tm)". But I had to throw it out there as a possibility. I appreciate any constructive feedback. Insults, chides, and arrogance will be scowled at, printed out and spat upon. -CH

A cheap and posibly very dangerous hack is to put your app as the default shell for a particular user. you need to be very careful though (suggestion chroot it to hell and back) as it might be possible to break out of the app and into the server.

You might consider using Pinax. When I used it, it had the self-concept of 'django with an opinion.' I'm not sure where it's at now, but my experience was that it was best suited for exactly what you want to do. One of the base projects is actually a fully functional social network site.

I have a concept I'd like to work on that requires the use of low-level sockets (i.e.: no frameworks or wrappers, just the standard send/recv pattern included in most standard libraries. I'm familiar with both Ruby and Python, and from my (limited) experience they seem to have similar socket libraries. What I'd like to know is if either language has any advantage, whether it be with performance, stability, ease-of-use or otherwise. Thanks.

I'm trying to create a python shell script to create a number of directories in Ubuntu Linux. The main directory I'm trying to create directories in is protected from write access. Is there a way to allow the Python script to be allowed to create directories in there as if it's the root user but not have to run the script through su, since other users might need to run the script but should not have su access?

You could create a separate command that creates the directory and make it setuid root (or, more safely, setuid or setgid to the owner of the parent directory). Make sure the command can't do anything other than what you want to allow it to do (e.g., don't let it pass its argument to system()). Then invoke that command from your Python script. Of course this will also enable any other process with execute permission on the new command to create subdirectories.

This question is not really related to Python. The Python script is just a process like any other process and needs to have to right permissions to do things. The usual method is to create a group, and make the parent directory g+ws for that group. Then add the appropriate users to that group as a supplemental group.

Unfortunately no. A process's permissions in a *nix environment are always less than or equal to the permissions of the person who fires it. This actually makes sense though -- it is a huge security risk to allow processes exceed the user's own abilities. This will require someone who has access to that directory -- either through one of their groups or through sudo. Either way, it will require human interaction on every machine that the script is run on. As far as what is easiest, well, you'll need someone who has that authority to grant it to another user, or simply use sudo directly.

You could add a user just for this task, then give the said user permissions for the directory you want the subdirectories created in and execute the script as the said user. There might be easier solutions but that's what comes to my mind at first glance.

Quickie here that needs more domain expertise on pymongo than I have right now: Are the "right" parts of the pymongo driver written in python for me to call gevent monkey_patch() and successfully alter pymongo's blocking behavior on r/w within gevent "asynchronous" greenlets? If this will require a little more leg work on gevent and pymongo -- but it is feasible -- I would be more than willing to put in the time as long as i can get a little guidance over irc. Thanks! Note: At small scale mongo writes are not a big problem because we are just queuing a write "request" before unblocking. BUT talking to fiorix about his twisted async mongo driver (https://github.com/fiorix/mongo-async-python-driver), even mongo's quick write (requests) can cause problems in asyncronous applications at scale. (And of course, non-blocking reads could cause problems from the start!)

On initial inspection it doesn't appear to do any socket operations in the c code so it should be fine (blocking ops should just block the green thread).

I have used PyMongo with Gevent and here are a few things you need to watch out for: Instantiate only one pymongo.Connection object, preferrably as a global or module-level variable. This is important because Connection has within itself a pool! Monkey patch everything, or at least BOTH socket and threading. Due to the use of thread locals in Connection, patching socket alone is not enough. Remember to call end_request to return the connection to the pool. The answer to your question is go ahead, PyMongo works just fine with Gevent.

First and foremost, make sure you have the newest version of gmake/make. I had a nasty problem using an older version. It was similar to this, which is why I am suggesting it. If you don't have it, install gmake and redo the python installation (./configure, make, make install). Hope that helps!

I wonder if is there any reliable and consistant way to get a Python package's "import name" / namespace. For example; Package; django-haystack Import name; haystack or Package; ipython Import name; IPython So far I know, PyPi doesn't store that information that I've checked with PyPiXmlRpc. I also tried to automate to download the package, extract it and dig the .egg-info but some packages doesn't have that folder at all. Any help will be appreciated and will be used for a good-manner gadget :)

Note that what you call a package here is not a package but a distribution. A distribution can contain zero or more modules or packages. That means there is no one-to-one mapping of distributions to packages. I'm not sure there is a way to detect what modules and packages will be installed by a distribution, other than actually installing it and introspect filesystem changes for newly added packages, modules and pth files.

bash loads a large number of commands from disk. Most other scripting languages have many more instructions that they run internally. For example, to do a simple computation in bash, you'd use a=`expr 1 + 2` and bash will first load /usr/bin/expr, run that command which writes the result in the output, bash collects the output (the ` quotes) and saves the result in the variable 'a'. That's definitively slow. The advantage of bash is the incredible flexibility though. Each person may have a different set of powerful "instructions". For example, I have a small tool called hex to print out numbers in octal, hexadecimal and decimal all at once. Other languages would not integrate in the way bash does...

My webhost where our website is runs Python 2.4 & the website uses the SQLite3 python module (which is only part of Python 2.5 & up). This means that I cant use the module SQLite3 because its not part of Python 2.4. Is there a way for me to upload the python SQLite3 module myself & just import/refernce that in my script? Do you know how I would do this? Usually I would just install Python25 on my webhost home directory, but this webhost wont allow me to do this. Is there any way I can just upload & import a specific module - coming from c++ it seems this must be possible right? Because in C++ I spend my whole life writting libraries & just importing specific parts of them & importing specific classes of a namespace & etc.

Since it's a clone I don't know what could be different but everytime I run my Fabric script I get the error Error reading SSH protocol banner.

We're running a pylons app with multiple ini files (production, staging, development, etc). When a new setting is added that can be the same in all environments, it would be great to be able to set it once in some sort of master configuration that gets included with all .ini files. Or included via some other way to load centralized config as well as deploy-specific config. It doesn't look like there's an "import" syntax for pylons ini files.

Nobody answered me, but I figured out the answer. Maybe it will help someone. I finally realized that since 'hg -y debuginstall' at the command line was giving me the same error message, it wasn't an Eclipse problem at all (duh). Reinstalling a newer version of Mercurial solved the problem.

I'm on Mac OS X 10.7.1 (Lion). I just downloaded a fresh copy of Eclipse IDE for Java EE Developers, and installed the Mercurial plugin. I get the following error message: abort: couldn't find mercurial libraries in [...assorted Python directories...]. I do have Python 2.6.1 and 3.2.1 installed. I also have a directory System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7, which is on the list of places it looked for the Mercurial libraries. hg -y debuginstall gives me the same message.

I had two installation of mercurial in mac. One was installed directly and another using macport. Removing the direct installation solved the problem. Remove the direct installation using easy_install -m mercurial Update "Mercurial Executable" path to "/opt/local/bin/hg" Eclipse->Preference->Team->Mercurial-> Restart eclipse

I think Github (Git) or Bitbucket/Kiln (Mercurial) would be the best places to host any code. That way you can keep it in version control + get comments, suggestions, and even features or additional code for free via the pull requests.

We're building a commercial (closed/proprietary) intranet application which makes used of hosted IronPython (2.7), targeting .NET 4.0. What approach would you recommend for ensuring the DLR runtimes (Microsoft.Scripting.dll & Microsoft.Dynamic.dll - both included in the IronPython 2.7 binary distribution) are available at runtime? They're both licensed under Apache license so including with our software wouldn't be a problem. Potentially an alternative would be ensuring they're available in the GAC. It seems the intention of the DLR developers is that more and more of the DLR will eventually end up in the .NET framework/CLR (presumably under System.Core). Any thoughts or considerations are appreciated.

The best thing to do is include the DLR DLLs in your application next to the IronPython DLLs. Putting them in the GAC will affect every other application on the system that uses the DLR, which is probably not what you want unless you have complete control of the systems involved. What's in .NET 4 is probably the extent of the DLR that's going to go in; Microsoft is not involved in the development of the DLR anymore.

In perl debugger I can use DB::get_fork_TTY() to debug both parent and child process in different terminals. Is there anything similar in python debugger? Or, is there any good way to debug fork in python?

But I'm still curious if there's any similar feature in python debugger. I happen to find this feature in perldb and I find it's very handy No. You don't need it. No matter how handy it may appear in other environments, you just don't need it. You don't need fork() in Python; therefore you don't need fancy debugging to work with fork(). If you think you need fork() you should either use subprocess, multiprocessing or C.

The debugger in pyCharm does this nicely. It seems to use gdb with python support to accomplish that, however all the tutorials on how to do this with gdb by Hand which I've found so far didn't work for me. In pyCharm it just works.

One possible way to debug a fork is to use pdb on the main process and winpdb on the fork. You put a software break early in the fork process and attach the winpdb app once the break has been hit. It might be possible to run the program under winpdb and attach another instance after the fork - I haven't tried this. You certainly can't attach two winpdb instances at the same time, I've tried and it fails. If it works, this would be preferable - pdb really sucks.

You can emulate forked process if you will set instead of fork and its condition (pid == 0) always True. For debugging main process debugger will work. For debugging multi-processing interaction better to use detailed logs as for me

We are running a very large framework of python scripts for test automation and I do really miss the opportunity to kill a running python script with ctrl + c in some situations on Windows. When the script might be doing some socket communications with long time-outs the only options sometimes is to kill the DOS window.. Is there any options I have missed?

Rather than using blocking calls with long timeouts, use event-driven networking. This will allow you never to have long periods of time doing uninterruptable operations.

I recently implemented password reset on AD using python ldap module. This involved passing modified attributes in this manner: add_pass = [(ldap.MOD_REPLACE, "unicodePwd", )] This worked since the passwords on AD are stored in attribute "unicodePwd". Now I want to unlock a locked user account but I cannot find the attribute that must be changed to achieve the same. Could you guys please tell me which attribute I have to change?

To unlock a user, you need to set the lockoutTime attribute to 0.

Test logic and tests should never be part of "production" (production can mean in use by you, released to client, etc.) code. So, it is a bad idea to have them anywhere within your script. Ideally, have them in separate files.

Best practice is to put the tests in separate units that use the unittest module. This separation allows you to keep the main code clean (no need for lots of testing helper functions) and encourages you to write good comprehensive tests since you are not inhibited by cluttering the main code.
