  • How to have PHP and mod_wsgi python app on the same domain?

    - by Lazik
    I am using apache with mod_wsgi (python3) on ubuntu 12.04. I have a python app (bottle) which is at www.mysite.com/ In my python app I have routes like www.mysite.com/abbb?q=blab I would like a path www.mysite.com/forum to resolve to a php app (simple machine forums) Ideally I would like to use apache to handle the forum part and pass it to php (instead of coding it in the python app). Don't know if it's possible. I'm new to this, I have read https://code.google.com/p/modwsgi/wiki/ConfigurationGuidelines#The_Apache_Alias_Directive but I don't understand how to use it. Here is my apache conf for the mod_wsgi app, I don't know how to specify the PHP portion. <VirtualHost *:80> ServerName www.ex.com ServerAlias ex.com *.ex.com RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}$1 [R=301,L] WSGIDaemonProcess ex user=www-data group=www-data processes=1 threads=5 WSGIScriptAlias / /var/www/vhosts/ex/app.wsgi <Directory /var/www/vhosts/ex> WSGIProcessGroup ex WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> </VirtualHost>

  • puppet execution of a python script where os.system(...) command is not working

    - by philippe
    I am trying to manage Unix users with puppet. Puppet provides enough tools to create accounts and provide authorized_keys files for instance, but no to set up user password, and it tell to the user. What I have done is a python script which generate a random password and send it to the user by email. The problem is, it is not possible to launch passwd Unix command with python, I have then written a bash script with the command: echo -ne "$password\n$password\n" | passwd $user passwd -e $user Launched manually, the script works fine and the created user has its password sent by email. But when puppet launches it, only the python script gets executed, as if the os.system('/bin/bash my_bash_script') is ignored. No error is displayed. And the user gets its password, but the passwd commands are not launched. Is there any limitation with puppet preventing to perform what I described? Or, how can I otherwise change the user account, its expiration, and send password by email? I can provide more information, but right now, I don't know which are accurate. Many thanks!

  • How to combine twill and python into one code that could be run on "Google App Engine"?

    - by brilliant
    Hello everybody!!! I have installed twill on my computer (having previously installed Python 2.5) and have been using it recently. Python is installed on disk C on my computer: C:\Python25 And the twill folder (“twill-0.9”) is located here: E:\tmp\twill-0.9 Here is a code that I’ve been using in twill: go “some website’s sign-in page URL” formvalue 2 userid “my login” formvalue 2 pass “my password” submit go “URL of some other page from that website” save_html result.txt This code helps me to log in to one website, in which I have an account, record the HTML code of some other page of that website (that I can access only after logging in), and store it in a file named “result.txt” (of course, before using this code I firstly need to replace “my login” with my real login, “my password” with my real password, “some website’s sign-in page URL” and “URL of some other page from that website” with real URLs of that website, and number 2 with the number of the form on that website that is used as a sign-in form on that website’s log-in page) This code I store in “test.twill” file that is located in my “twill-0.9” folder: E:\tmp\twill-0.9\test.twill I run this file from my command prompt: python twill-sh test.twill Now, I also have installed “Google App Engine SDK” from “Google App Engine” and have also been using it for awhile. For example, I’ve been using this code: import hashlib m = hashlib.md5() m.update("Nobody inspects") m.update(" the spammish repetition ") print m.hexdigest() This code helps me transform the phrase “Nobody inspects the spammish repetition” into md5 digest. Now, how can I put these two pieces of code together into one python script that I could run on “Google App Engine”? Let’s say, I want my code to log in to a website from “Google App Engine”, go to another page on that website, record its HTML code (that’s what my twill code does) and than transform this HTML code into its md5 digest (that’s what my second code does). So, how can I combine those two codes into one python code? I guess, it should be done somehow by importing twill, but how can it be done? Can a python code - the one that is being run by “Google App Engine” - import twill from somewhere on the internet? Or, perhaps, twill is already installed on “Google App Engine”?

  • How can I build the Boost.Python example on Ubuntu 9.10?

    - by Gatlin
    I am using Ubuntu 9.10 beta, whose repositories contain boost 1.38. I would like to build the hello-world example. I followed the instructions here (http://www.boost.org/doc/libs/1%5F40%5F0/libs/python/doc/tutorial/doc/html/python/hello.html), found the example project, and issued the "bjam" command. I have installed bjam and boost-build. I get the following output: Jamroot:18: in modules.load rule python-extension unknown in module Jamfile</usr/share/doc/libboost1.38-doc/examples/libs/python/example>. /usr/share/boost-build/build/project.jam:312: in load-jamfile /usr/share/boost-build/build/project.jam:68: in load /usr/share/boost-build/build/project.jam:170: in project.find /usr/share/boost-build/build-system.jam:248: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/doc/libboost1.38-doc/examples/libs/python/example/boost-build.jam:7: in module scope I do not know enough about Boost (this is an exploratory exercise for myself) to understand why the python-extension macro in the included Jamroot is not valid. I am running this example from the install directory, so I have not altered the Jamroot's use-project setting. As a side question, if I were to just willy-nilly start a project in an arbitrary directory, how would I write my jamroot?

  • Optimization in Python - do's, don'ts and rules of thumb.

    - by JV
    Well I was reading this post and then I came across a code which was: jokes=range(1000000) domain=[(0,(len(jokes)*2)-i-1) for i in range(0,len(jokes)*2)] I thought wouldn't it be better to calculate the value of len(jokes) once outside the list comprehension? Well I tried it and timed three codes jv@Pioneer:~$ python -m timeit -s 'jokes=range(1000000);domain=[(0,(len(jokes)*2)-i-1) for i in range(0,len(jokes)*2)]' 10000000 loops, best of 3: 0.0352 usec per loop jv@Pioneer:~$ python -m timeit -s 'jokes=range(1000000);l=len(jokes);domain=[(0,(l*2)-i-1) for i in range(0,l*2)]' 10000000 loops, best of 3: 0.0343 usec per loop jv@Pioneer:~$ python -m timeit -s 'jokes=range(1000000);l=len(jokes)*2;domain=[(0,l-i-1) for i in range(0,l)]' 10000000 loops, best of 3: 0.0333 usec per loop Observing the marginal difference 2.55% between the first and the second made me think - is the first list comprehension domain=[(0,(len(jokes)*2)-i-1) for i in range(0,len(jokes)*2)] optimized internally by python? or is 2.55% a big enough optimization (given that the len(jokes)=1000000)? If this is - What are the other implicit/internal optimizations in Python ? What are the developer's rules of thumb for optimization in Python? Edit1: Since most of the answers are "don't optimize, do it later if its slow" and I got some tips and links from Triptych and Ali A for the do's. I will change the question a bit and request for don'ts. Can we have some experiences from people who faced the 'slowness', what was the problem and how it was corrected? Edit2: For those who haven't here is an interesting read Edit3: Incorrect usage of timeit in question please see dF's answer for correct usage and hence timings for the three codes.

  • Why does Ruby have Rails while Python has no central framework?

    - by yar
    This is a(n) historical question, not a comparison-between-languages question: This article from 2005 talks about the lack of a single, central framework for Python. For Ruby, this framework is clearly Rails. Why, historically speaking, did this happen for Ruby but not for Python? (or did it happen, and that framework is Django?) Also, the hypothetical questions: would Python be more popular if it had one, good framework? Would Ruby be less popular if it had no central framework? [Please avoid discussions of whether Ruby or Python is better, which is just too open-ended to answer.] Edit: Though I thought this is obvious, I'm not saying that other frameworks do not exist for Ruby, but rather that the big one in terms of popularity is Rails. Also, I should mention that I'm not saying that frameworks for Python are not as good (or better than) Rails. Every framework has its pros and cons, but Rails seems to, as Ben Blank says in the one of the comments below, have surpassed Ruby in terms of popularity. There are no examples of that on the Python side. WHY? That's the question.

  • How do I set up the python/c library correctly?

    - by Bartvbl
    I have been trying to get the python/c library to like my mingW compiler. The python online doncumentation; http://docs.python.org/c-api/intro.html#include-files only mentions that I need to import the python.h file. I grabbed it from the installation directory (as is required on the windows platform), and tested it by compiling the script: #include "Python.h". This compiled fine. Next, I tried out the snippet of code shown a bit lower on the python/c API page: PyObject *t; t = PyTuple_New(3); PyTuple_SetItem(t, 0, PyInt_FromLong(1L)); PyTuple_SetItem(t, 1, PyInt_FromLong(2L)); PyTuple_SetItem(t, 2, PyString_FromString("three")); For some reason, the compiler would compile the code if I'd remove the last 4 lines (so that only the pyObject variable definition would be left), yet calling the actual constructor of the tuple returned errors. I am probably missing something completely obvious here, given I am very new to C, but does anyone know what it is?

  • Where should executables be run from? Network share or client?

    - by user74150
    We have an executable that is used by 50+ client machines on a network and upgraded regularly. Is it acceptable to put the executable on a network share and have the client machines run it from there via a shortcut on their desktop? That way when we upgrade the .exe we can simply replace the one file with a new one and all clients will be accessing the new one. How will a slow or unstable network handle this? If this is not acceptable, what would be the best way to keep all clients updated with the latest .exe?

  • Why is VMware vSphere Client hanging at the console?

    - by David
    When I use the vSphere Client (against an ESXi 4.1 server) it hangs a lot. It's always at the same place - using the console on a VM. The console stops responding - and a lot of times, the management window stops responding as well. The operating system won't close the window (as the application isn't responding) and requires a force close. I've had the console refuse to give up the mouse, and have had the console freeze with the cursor in the top left (before any VM software starts, maybe?). The environment is this: the system is a Dell laptop running Ubuntu 10.10 (Maverick) fully updated with VirtualBox OSE running Windows XP (also fully updated). The vSphere Client is running in the Windows XP VM. Got all that? How do I keep these hangs from happening? It is very aggravating. I'm still trying just to get the VM loaded with Ubuntu Server...

  • Trouble installing Mercurial 1.5 on Mac OS X 10.5.8 (without using MacPorts)

    - by gjvis
    I'm having trouble installing Mercurial 1.5 (build 20100307) from the prebuilt installer on Mac OS X 10.5.8. The installer is halting telling me that I need to install Python 2.6 to continue. I've installed the latest version of Python (2.6.5) twice now but it's not helping. which python is reporting /Library/Frameworks/Python.framework/Versions/2.6/bin/python, but I can see that I also have 2.3 and 2.5 in /System/Library/Frameworks/Python.framework/Versions directory, which I suspect is being picked up by the installer ahead of the 2.6 install. If possible I'd like to install Mercurial and Python without having to resort to MacPorts, but if that is the only option then so be it :)

  • How to know when the Client is disconnected from Server in C#?

    - by menacheb
    Hi, I have a Client-Server program in C#. Here is the Server's code: ... String dataFromClient = ""; NetworkStream networkStream; TcpClient clientSocket; bool transfer = true; ... while (transfer) { networkStream = clientSocket.GetStream(); networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize); dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom); dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$")); .... } I want to make a condition that stop the loop when the Client is disconnected. How can I do that? Many thanks,

  • Mac OS X multi-user thin client server (terminal server)?

    - by username
    Is there any solution out there to turn a Mac into a true multi-user thin client server? I'd like to set up a few cheap PCs with access to a couple accounts using something like VNC, but it isn't economical to buy a new server for each user or a new license for virtualized OS X Server for each user. I'm fully aware that OS X Server lets you set up users with "network home folders," and I know there's also VNC built into Mac OS X. Neither of these fit the bill (the former requires a thick client, and the latter is single-user only) UPDATE: yay, Lion! http://www.9to5mac.com/54102/10-7-lion-allows-multi-user-remote-computing

  • Bacula windows client could not connect to Bacula director

    - by pr0f-r00t
    I have a Bacula server on my Linux Debian squeeze host (Bacula version 5.0.2) and a Bacula client on Windows XP SP3. On my network each client can see each other, can share files and can ping.

  • Detect user logout / shutdown in Python / GTK under Linux

    - by Ivo Wetzel
    OK this is presumably a hard one, I've got an pyGTK application that has random crashes due to X Window errors that I can't catch/control. So I created a wrapper that restarts the app as soon as it detects a crash, now comes the problem, when the user logs out or shuts down the system, the app exits with status 1. But on some X errors it does so too. So I tried literally anything to catch the shutdown/logout, with no success, here's what I've tried: import pygtk import gtk import sys class Test(gtk.Window): def delete_event(self, widget, event, data=None): open("delete_event", "wb") def destroy_event(self, widget, data=None): open("destroy_event", "wb") def destroy_event2(self, widget, event, data=None): open("destroy_event2", "wb") def __init__(self): gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL) self.show() self.connect("delete_event", self.delete_event) self.connect("destroy", self.destroy_event) self.connect("destroy-event", self.destroy_event2) def foo(): open("add_event", "wb") def ex(): open("sys_event", "wb") from signal import * def clean(sig): f = open("sig_event", "wb") f.write(str(sig)) f.close() exit(0) for sig in (SIGABRT, SIGILL, SIGINT, SIGSEGV, SIGTERM): signal(sig, lambda *args: clean(sig)) def at(): open("at_event", "wb") import atexit atexit.register(at) f = Test() sys.exitfunc = ex gtk.quit_add(gtk.main_level(), foo) gtk.main() open("exit_event", "wb") Not one of these succeeds, is there any low level way to detect the system shutdown? Google didn't find anything related to that. I guess there must be a way, am I right? :/

  • Python Tkinter Tix: How to use ScrolledWindow with grid in Tix NoteBook

    - by Sano98
    Hi guys, I'm adding several widgets to a Frame which is located in a tix.NoteBook. When there are too much widgets to fit in the window, I want to use a scrollbar, so I put tix.ScrolledWindow inside that Frame and add my widgets to this ScrolledWindow instead. The problem is that when using the grid() geometry manager, the scrollbar appears, but it is not working (The drag bar occupies the whole scroll bar). from Tkinter import * import Tix class Window: def __init__(self, root): self.labelList = [] self.notebook = Tix.NoteBook(root, ipadx=3, ipady=3) self.notebook.add('sheet_1', label="Sheet 1", underline=0) self.notebook.add('sheet_2', label="Sheet 2", underline=0) self.notebook.add('sheet_3', label="Sheet 3", underline=0) self.notebook.pack() #self.notebook.grid(row=0, column=0) tab1=self.notebook.sheet_1 tab2=self.notebook.sheet_2 tab3=self.notebook.sheet_3 self.myMainContainer = Frame(tab1) self.myMainContainer.pack() #self.myMainContainer.grid(row=0, column=0) scrwin = Tix.ScrolledWindow(self.myMainContainer, scrollbar='y') scrwin.pack() #scrwin.grid(row=0, column=0) self.win = scrwin.window for i in range (100): self.labelList.append((Label(self.win))) self.labelList[-1].config(text= "Bla", relief = SUNKEN) self.labelList[-1].grid(row=i, column=0, sticky=W+E) root = Tix.Tk() myWindow = Window(root) root.mainloop() Whenever I change at least one of the geometry managers from pack() to grid(), the problem occurs. (Actually, I'd prefer using grid() for all containers.) When I don't use the NoteBook widget, the problem does not occur either. The other examples here all seem to rely on pack(). Any ideas? Many thanks, Sano

  • video player with qt phonon (using python)

    - by cppb
    hi, I am working on Windows xp and am trying to get a simple video player running. I am trying to use Phonon::VideoPlayer module for this. I am connecting the signal as connect(self.player,SIGNAL("finished()"),self.player.deleteLater) and then , when the Play button is pressed, it makes the following call: self.player.play(Phonon.MediaSource("C:\vid.mp4")) But, this doesn't display the video in the video player widget. Neither can I hear audio. Can anyone help?? I tried using different video file formats but no luck.

  • Python: nonblocking read from stdout of threaded subprocess

    - by sberry2A
    I have a script (worker.py) that prints unbuffered output in the form... 1 2 3 . . . n where n is some constant number of iterations a loop in this script will make. In another script (service_controller.py) I start a number of threads, each of which starts a subprocess using subprocess.Popen(stdout=subprocess.PIPE, ...); Now, in my main thread (service_controller.py) I want to read the output of each thread's worker.py subprocess and use it to calculate an estimate for the time remaining till completion. I have all of the logic working that reads the stdout from worker.py and determines the last printed number. The problem is that I can not figure out how to do this in a non-blocking way. If I read a constant bufsize then each read will end up waiting for the same data from each of the workers. I have tried numerous ways including using fcntl, select + os.read, etc. What is my best option here? I can post my source if needed, but I figured the explanation describes the problem well enough. Thanks for any help here. EDIT Adding sample code I have a worker that starts a subprocess. class WorkerThread(threading.Thread): def __init__(self): self.completed = 0 self.process = None self.lock = threading.RLock() threading.Thread.__init__(self) def run(self): cmd = ["/path/to/script", "arg1", "arg2"] self.process = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1, shell=False) #flags = fcntl.fcntl(self.process.stdout, fcntl.F_GETFL) #fcntl.fcntl(self.process.stdout.fileno(), fcntl.F_SETFL, flags | os.O_NONBLOCK) def get_completed(self): self.lock.acquire(); fd = select.select([self.process.stdout.fileno()], [], [], 5)[0] if fd: self.data += os.read(fd, 1) try: self.completed = int(self.data.split("\n")[-2]) except IndexError: pass self.lock.release() return self.completed I then have a ThreadManager. class ThreadManager(): def __init__(self): self.pool = [] self.running = [] self.lock = threading.Lock() def clean_pool(self, pool): for worker in [x for x in pool is not x.isAlive()]: worker.join() pool.remove(worker) del worker return pool def run(self, concurrent=5): while len(self.running) + len(self.pool) > 0: self.clean_pool(self.running) n = min(max(concurrent - len(self.running), 0), len(self.pool)) if n > 0: for worker in self.pool[0:n]: worker.start() self.running.extend(self.pool[0:n]) del self.pool[0:n] time.sleep(.01) for worker in self.running + self.pool: worker.join() and some code to run it. threadManager = ThreadManager() for i in xrange(0, 5): threadManager.pool.append(WorkerThread()) threadManager.run() I have stripped out a log of the other code in hopes to try to pinpoint the issue.

  • Python: combine logging and wx so that logging stream is redirectet to stdout/stderr frame

    - by Uwe
    Here's the thing: I'm trying to combine the logging module with wx.App()'s redirect feature. My intention is to log to a file AND to stderr. But I want stderr/stdout redirected to a separate frame as is the feature of wx.App. My test code: import logging import wx class MyFrame(wx.Frame): def __init__(self): self.logger = logging.getLogger("main.MyFrame") wx.Frame.__init__(self, parent = None, id = wx.ID_ANY, title = "MyFrame") self.logger.debug("MyFrame.__init__() called.") def OnExit(self): self.logger.debug("MyFrame.OnExit() called.") class MyApp(wx.App): def __init__(self, redirect): self.logger = logging.getLogger("main.MyApp") wx.App.__init__(self, redirect = redirect) self.logger.debug("MyApp.__init__() called.") def OnInit(self): self.frame = MyFrame() self.frame.Show() self.SetTopWindow(self.frame) self.logger.debug("MyApp.OnInit() called.") return True def OnExit(self): self.logger.debug("MyApp.OnExit() called.") def main(): logger_formatter = logging.Formatter("%(name)s\t%(levelname)s\t%(message)s") logger_stream_handler = logging.StreamHandler() logger_stream_handler.setLevel(logging.INFO) logger_stream_handler.setFormatter(logger_formatter) logger_file_handler = logging.FileHandler("test.log", mode = "w") logger_file_handler.setLevel(logging.DEBUG) logger_file_handler.setFormatter(logger_formatter) logger = logging.getLogger("main") logger.setLevel(logging.DEBUG) logger.addHandler(logger_stream_handler) logger.addHandler(logger_file_handler) logger.info("Logger configured.") app = MyApp(redirect = True) logger.debug("Created instance of MyApp. Calling MainLoop().") app.MainLoop() logger.debug("MainLoop() ended.") logger.info("Exiting program.") return 0 if (__name__ == "__main__"): main() Expected behavior is: - a file is created named test.log - the file contains logging messages with level DEBUG and INFO/ERROR/WARNING/CRITICAL - messages from type INFO and ERROR/WARNING/CRITICAL are ether shown on the console or in a separate frame, depending on where they are created - logger messages that are not inside MyApp or MyFrame are displayed at the console - logger messages from inside MyApp or MyFrame are shown in a separate frame Actual behavior is: - The file is created and contains: main INFO Logger configured. main.MyFrame DEBUG MyFrame.__init__() called. main.MyFrame INFO MyFrame.__init__() called. main.MyApp DEBUG MyApp.OnInit() called. main.MyApp INFO MyApp.OnInit() called. main.MyApp DEBUG MyApp.__init__() called. main DEBUG Created instance of MyApp. Calling MainLoop(). main.MyApp DEBUG MyApp.OnExit() called. main DEBUG MainLoop() ended. main INFO Exiting program. - Console output is: main INFO Logger configured. main.MyFrame INFO MyFrame.__init__() called. main.MyApp INFO MyApp.OnInit() called. main INFO Exiting program. - No separate frame is opened, although the lines main.MyFrame INFO MyFrame.__init__() called. main.MyApp INFO MyApp.OnInit() called. shouldget displayed within a frame and not on the console. It seems to me that wx.App can't redirect stderr to a frame as soon as a logger instance uses stderr as output. wxPythons Docs claim the wanted behavior though, see here. Any ideas? Uwe

  • Python Image Library, Close method

    - by DNN
    Hello, I have been using pil for the first time today. And I wanted to resize an image assuming it was larger than 800x600 and also create a thumbnail. I could do either of these tasks separately but not together in one method (I am doing a custom save method in django admin). This returns a "cannot identify image file" error message. The error is on the line "image = Image.open(self.photo)" after "#if image is size is greatet than 800 x 600 then resize image." I thought this may be because the image is already open, but if i remove the line I still get issues. So I thought I could try closing after creating a thumbnail and then reopening. But I couldn't find a close method.... This is my code: def save(self): #create thumbnail Thumb_Size = (75, 75) image = Image.open(self.photo) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Thumb_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.thumbnail.save(suf.name+'.jpg', suf, save=False) #if image is size is greatet than 800 x 600 then resize image. image = Image.open(self.photo) if image.size[0] > 800: if image.size[1] > 600: Max_Size = (800, 600) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Max_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.photo.save(suf.name+'.jpg', suf, save=False) #enter info to database super(Photo, self).save()

  • Simple implementation of N-Gram, tf-idf and Cosine similarity in Python

    - by seanieb
    I need to compare documents stored in a DB and come up with a similarity score between 0 and 1. The method I need to use has to be very simple. Implementing a vanilla version of n-grams (where it possible to define how many grams to use), along with a simple implementation of tf-idf and Cosine similarity. Is there any program that can do this? Or should I start writing this from scratch?
