• How to determine subprocess.Popen() failed when shell=True

  - by Malcolm

  Windows version of Python 2.6.4: Is there any way to determine if subprocess.Popen() fails when using shell=True? Popen() successfully fails when shell=False >>> import subprocess >>> p = subprocess.Popen( 'Nonsense.application', shell=False ) Traceback (most recent call last): File ">>> pyshell#258", line 1, in <module> p = subprocess.Popen( 'Nonsense.application' ) File "C:\Python26\lib\subprocess.py", line 621, in __init__ errread, errwrite) File "C:\Python26\lib\subprocess.py", line 830, in _execute_child startupinfo) WindowsError: [Error 2] The system cannot find the file specified But when shell=True, there appears to be no way to determine if a Popen() call was successful or not. >>> p = subprocess.Popen( 'Nonsense.application', shell=True ) >>> p >>> subprocess.Popen object at 0x0275FF90&gt;&gt;&gt; >>> p.pid 6620 >>> p.returncode >>> Ideas appreciated. Regards, Malcolm

• wxPython, Threads, and PostEvent between modules

  - by Sam Starling

  I'm relatively new to wxPython (but not Python itself), so forgive me if I've missed something here. I'm writing a GUI application, which at a very basic level consists of "Start" and "Stop" buttons that start and stop a thread. This thread is an infinite loop, which only ends when the thread is stopped. The loop generates messages, which at the moment are just output using print. The GUI class and the infinite loop (using threading.Thread as a subclass) are held in separate files. What is the best way to get the thread to push an update to something like a TextCtrl in the GUI? I've been playing around with PostEvent and Queue, but without much luck. Here's some bare bones code, with portions removed to keep it concise: main_frame.py import wx from loop import Loop class MainFrame(wx.Frame): def __init__(self, parent, title): # Initialise and show GUI # Add two buttons, btnStart and btnStop # Bind the two buttons to the following two methods self.threads = [] def onStart(self): x = Loop() x.start() self.threads.append(x) def onStop(self): for t in self.threads: t.stop() loop.py class Loop(threading.Thread): def __init__(self): self._stop = threading.Event() def run(self): while not self._stop.isSet(): print datetime.date.today() def stop(self): self._stop.set() I did, at one point, have it working by having the classes in the same file by using wx.lib.newevent.NewEvent() along these lines. If anyone could point me in the right direction, that'd be much appreciated.

• Troubles with PyDev and external libraries in OS X

  - by Davide Gualano

  I've successfully installed the latest version of PyDev in my Eclipse (3.5.1) under OS X 10.6.3, with python 2.6.1 I have troubles in making the libraries I have installed work. For example, I'm trying to use the cx_Oracle library, which is perfectly working if called from the python interpeter of from simple scripts made with some text editor. But I cant make it work inside Eclipse: I have this small piece of code: import cx_Oracle conn = cx_Oracle.connect(CONN_STRING) sql = "select field from mytable" cursor = conn.cursor() cursor.execute(sql) for row in cursor: field = row[0] print field If I execute it from Eclipse, I get the following error: import cx_Oracle File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 7, in <module> File "build/bdist.macosx-10.6-universal/egg/cx_Oracle.py", line 6, in __bootstrap__ ImportError: dlopen(/Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so, 2): Library not loaded: /b/227/rdbms/lib/libclntsh.dylib.10.1 Referenced from: /Users/dave/.python-eggs/cx_Oracle-5.0.3-py2.6-macosx-10.6-universal.egg-tmp/cx_Oracle.so Reason: no suitable image found.

• Converting a bash script to python (small script)

  - by Mestika

  Hi, I’ve a bash script I’ve been using for a Linux environment but now I have to use it on a Windows platform and want to convert the bash script to a python script which I can run. The bash script is rather simple (I think) and I’ve tried to convert it by google by way around but can’t convert it successfully. The bash script looks like this: runs=5 queries=50 outfile=outputfile.txt date >> $outfile echo -e "\n---------------------------------" echo -e "\n----------- Normal --------------" echo -e "\n---------------------------------" echo -e "\n----------- Normal --------------" >> $outfile for ((r = 1; r < ($runs + 1); r++)) do echo -e "Run $r of $runs\n" db2 FLUSH PACKAGE CACHE DYNAMIC python reads.py -r1 -pquery1.sql -q$queries -shotelspec -k6 -a5 >> $outfile done The main command, the python read.py … etc. is another python file I’ve been given and have the arguments as you see. I know it is a lot to ask for, but it would really help me out if someone could convert this to a python script I can use or at least give me some hints and directions. Sincerely Mestika

• Django tests failing on invalid keyword argument

  I have a models.py like so: from django.db import models from django.contrib.auth.models import User from datetime import datetime class UserProfile(models.Model): user = models.OneToOneField(User) def __unicode__(self): return self.user.username class Project(models.Model): user = models.ForeignKey(UserProfile) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) product = models.ForeignKey('tool.product') module = models.ForeignKey('tool.module') model = models.ForeignKey('tool.model') zipcode = models.IntegerField(max_length=5) def __unicode__(self): return unicode(self.id) And my tests.py: from django.test import TestCase, Client # --- import app models from django.contrib.auth.models import User from tool.models import Module, Model, Product from user_profile.models import Project, UserProfile # --- unit tests --- # class UserProjectTests(TestCase): fixtures = ['admin_user.json'] def setUp(self): self.product1 = Product.objects.create( name='bar', ) self.module1 = Module.objects.create( name='foo', enable=True ) self.model1 = Model.objects.create( module=self.module1, name='baz', enable=True ) self.user1 = User.objects.get(pk=1) ... def test_can_create_project(self): self.project1 = Model.objects.create( user=self.user1, product=self.product1, module=self.module1, model=self.model1, zipcode=90210 ) self.assertEquals(self.project1.zipcode, 90210) But I get a TypeError: 'product' is an invalid keyword argument for this function error. I'm not sure what is failing but I'm guessing something to do with the FK relationships... Any help would be much appreciated.

• Python: puzzling behaviour inside httplib

  - by Anna

  I have added one line ( import pdb; pdb.set_trace() ) to httplib's HTTPConnection.putheader, so I can see what's going on inside. httplib.py, line 489: def putheader(self, header, value): """Send a request header line to the server. For example: h.putheader('Accept', 'text/html') """ import pdb; pdb.set_trace() if self.__state != _CS_REQ_STARTED: raise CannotSendHeader() str = '%s: %s' % (header, value) self._output(str) then ran this from the interpreter import urllib2 urllib2.urlopen('http://www.ioerror.us/ip/headers') ... and as expected PDB kicks in: > c:\python26\lib\httplib.py(858)putheader() -> if self.__state != _CS_REQ_STARTED: (Pdb) in PDB I have the luxury of evaluating expressions on the fly, so I have tried to enter self.__state: (Pdb) self.__state *** AttributeError: HTTPConnection instance has no attribute '__state' Alas, there is no __state of this instance. However when I enter step, the debugger gets past the if self.__state != _CS_REQ_STARTED: line without a problem. Why is this happening? If the self.__state doesn't exist python would have to raise an exception as it did when I entered the expression. Python version: 2.6.4 on win32

• Django-South introspection rule doesn't work.

  - by Ory Band

  I'm using Django 1.2.3 and South 0.7.3. I am trying to convert my app (named core) to use Django-South. I have a custom model/field that I'm using, named ImageWithThumbsField. It's basically just the ol' django.db.models.ImageField with some attributes such as height, weight, etc. While trying to ./manage.py convert_to_auth core I receieve South's freezing errors. I have no idea why, I'm Probably missing something... I am using a simple custom Model: from django.db.models import ImageField class ImageWithThumbsField(ImageField): def __init__(self, verbose_name=None, name=None, width_field=None, height_field=None, sizes=None, **kwargs): self.verbose_name=verbose_name self.name=name self.width_field=width_field self.height_field=height_field self.sizes = sizes super(ImageField, self).__init__(**kwargs) And this is my introspection rule, which I add to the top of my models.py: from south.modelsinspector import add_introspection_rules from lib.thumbs import ImageWithThumbsField add_introspection_rules( [ ( (ImageWithThumbsField, ), [], { "verbose_name": ["verbose_name", {"default": None}], "name": ["name", {"default": None}], "width_field": ["width_field", {"default": None}], "height_field": ["height_field", {"default": None}], "sizes": ["sizes", {"default": None}], }, ), ], ["^core/.fields/.ImageWithThumbsField",]) This is the errors I receieve: ! Cannot freeze field 'core.additionalmaterialphoto.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.photo' ! (this field has class lib.thumbs.ImageWithThumbsField) ! Cannot freeze field 'core.material.formulaimage' ! (this field has class lib.thumbs.ImageWithThumbsField) ! South cannot introspect some fields; this is probably because they are custom ! fields. If they worked in 0.6 or below, this is because we have removed the ! models parser (it often broke things). ! To fix this, read http://south.aeracode.org/wiki/MyFieldsDontWork Does anybody know why? What am I doing wrong?

• A UnicodeDecodeError that occurs with json in python on Windows, but not Mac.

  - by ventolin

  On windows, I have the following problem: >>> string = "Don´t Forget To Breathe" >>> import json,os,codecs >>> f = codecs.open("C:\\temp.txt","w","UTF-8") >>> json.dump(string,f) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python26\lib\json\__init__.py", line 180, in dump for chunk in iterable: File "C:\Python26\lib\json\encoder.py", line 294, in _iterencode yield encoder(o) UnicodeDecodeError: 'utf8' codec can't decode bytes in position 3-5: invalid data (Notice the non-ascii apostrophe in the string.)

I've also tried using UTF-16 and UTF-32 with json and codecs, but to no avail.

• Debugging Django project problem.

  - by Wasim

  Hi all, I asked this question before, but had no replies, maybe I wasn't so clear. I'm trying to debug a django project using MySQL database. If I run the admin or trying to use the shell to communicate to the data base every thing is well and I can do every thing. I installed MySQLdb for Python 2.6. I installed PyDev on my Apatana studio. Configured the Debugging with runserver 8001 --noreload. When I start debugging , When I arrive to the following code in C:\Python26\Lib\site-packages\django\db\backends\mysql\base.py try: import MySQLdb as Database except ImportError, e: from django.core.exceptions import ImproperlyConfigured raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) I get an import error : django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: DLL load failed: The specified module could not be found. I trying to ge more deeply with the import MySQLdb as Database line , it goes to the C:\Python26\Lib\site-packages\MySQLdb__init__.py and fail in the line import _mysql. I can't understand the problem. When running the Django admin every thing is ok, but with debugging it fails to work. Any help please. Thanks in advance.

• rotate an image aroound a point

  - by Girish

  Hi all, I have an image which is of rectangular dimension, eg 30 x 60 pixels I want to rotate this image around the bottom center of the image, i.e i want to set the pivot in the above example as (15, 60 )pixel. I am using a drawble and matrix to get this done, whatever i try i always end up rotating around center of the image. Code is : Bitmap bitmapOrg = BitmapFactory.decodeFile("/sdcard/DCIM/2010-06-01_15-32-42_821.jpg"); // float angle = (angle + 10.0f)%360.0f; if(null !=bitmapOrg) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 15; int newHeight = 15; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; /* Canvas c = new Canvas(bitmapOrg); float px = ; float py; c.rotate(angle, px, py)*/ // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // rotate the Bitmap // matrix.postRotate(45); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); // make a Drawable from Bitmap to allow to set the BitMap // to the ImageView, ImageButton or what ever BitmapDrawable bmd = new BitmapDrawable(resizedBitmap); ImageView imageView = new ImageView(this); // set the Drawable on the ImageView imageView.setImageDrawable(bmd); // center the Image imageView.setScaleType(ScaleType.CENTER); // imageView.layout(100, 300, 0, 0); // linLayout.addView(imageView); // add ImageView to the Layout linLayout.addView(imageView, new AbsoluteLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 10, 30 ) ); can anyone let me know how to get this rectified?

• cgi.FieldStorage always empty - never returns POSTed form Data

  - by Dan Carlson

  This problem is probably embarrassingly simple. I'm trying to give python a spin. I thought a good way to start doing that would be to create a simple cgi script to process some form data and do some magic. My python script is executed properly by apache using mod_python, and will print out whatever I want it to print out. My only problem is that cgi.FieldStorage() is always empty. I've tried using both POST and GET. Each trial I fill out both form fields. <form action="pythonScript.py" method="POST" name="ARGH"> <input name="TaskName" type="text" /> <input name="TaskNumber" type="text" /> <input type="submit" /> </form> If I change the form to point to a perl script it reports the form data properly. The python page always gives me the same result: number of keys: 0 #!/usr/bin/python import cgi def index(req): pageContent = """<html><head><title>A page from""" pageContent += """Python</title></head><body>""" form = cgi.FieldStorage() keys = form.keys() keys.sort() pageContent += "<br />number of keys: "+str(len(keys)) for key in keys: pageContent += fieldStorage[ key ].value pageContent += """</body></html>""" return pageContent I'm using Python 2.5.2 and Apache/2.2.3. This is what's in my apache conf file (and my script is in /var/www/python): <Directory /var/www/python/> Options FollowSymLinks +ExecCGI Order allow,deny allow from all AddHandler mod_python .py PythonHandler mod_python.publisher </Directory>

• Django: Serving Media Behind Custom URL

  - by TheLizardKing

  So I of course know that serving static files through Django will send you straight to hell but I am confused on how to use a custom url to mask the true location of the file using Django. http://stackoverflow.com/questions/2681338/django-serving-a-download-in-a-generic-view but the answer I accepted seems to be the "wrong" way of doing things. urls.py: url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'), views.py: def song_download(request, song_id): song = Song.objects.get(id=song_id) fsock = open(os.path.join(song.path, song.filename)) response = HttpResponse(fsock, mimetype='audio/mpeg') response['Content-Disposition'] = "attachment; filename=%s - %s.mp3" % (song.artist, song.title) return response This solution works perfectly but not perfectly enough it turns out. How can I avoid having a direct link to the mp3 while still serving through nginx/apache? EDIT 1 - ADDITIONAL INFO Currently I can get my files by using an address such as: http://www.example.com/music/song/1692/download/ But the above mentioned method is the devil's work. How can I accomplished what I get above while still making nginx/apache serve the media? Is this something that should be done at the webserver level? Some crazy mod_rewrite? http://static.example.com/music/Aphex%20Twin%20-%20Richard%20D.%20James%20(V0)/10%20Logon-Rock%20Witch.mp3

• Django internationalization for admin pages - translate model name and attributes

  - by geekQ

  Django's internationalization is very nice (gettext based, LocaleMiddleware), but what is the proper way to translate the model name and the attributes for admin pages? I did not find anything about this in the documentation: http://docs.djangoproject.com/en/dev/topics/i18n/internationalization/ http://www.djangobook.com/en/2.0/chapter19/ I would like to have "???????? ????? ??? ?????????" instead of "???????? order ??? ?????????". Note, the 'order' is not translated. First, I defined a model, activated USE_I18N = True in settings.py, run django-admin makemessages -l ru. No entries are created by default for model names and attributes. Grepping in the Django source code I found: $ ack "Select %s to change" contrib/admin/views/main.py 70: self.title = (self.is_popup and ugettext('Select %s') % force_unicode(self.opts.verbose_name) or ugettext('Select %s to change') % force_unicode(self.opts.verbose_name)) So the verbose_name meta property seems to play some role here. Tried to use it: class Order(models.Model): subject = models.CharField(max_length=150) description = models.TextField() class Meta: verbose_name = _('order') Now the updated po file contains msgid 'order' that can be translated. So I put the translation in. Unfortunately running the admin pages show the same mix of "???????? order ??? ?????????". I'm currently using Django 1.1.1. Could somebody point me to the relevant documentation? Because google can not. ;-) In the mean time I'll dig deeper into the django source code...

• Debian packaging of a Python package.

  - by chrisdew

  I need to write (or find) a script to create a Debian package (using python-support) from a Python package. The Python package will be pure Python (no C extensions). The Python package (for testing purposes) will just be a directory with an empty __init__.py file and a single Python module, package_test.py. The packaging script must use python-support to provide the correct bytecode for possible multiple installations of Python on a target platform. (i.e. v2.5 and v2.6 on Ubuntu Jaunty.) Most advice I find while googling are just examples nasty hacks that don't even use python-support or python-central. I have so far spent hours researching this, and the best I can come up with is to hack around the script from an existing open source project - but I don't know which bits are required for what I'm doing. Has anyone here made a Debian package out of a Python package in a reasonably non-hacky way? I'm starting to think that it will take me more than a week to go from no knowledge of Debian packaging and python-support to getting a working script. How long has it taken others? Any advice? Chris.

• Django Image Upload: IOErrno2 Could not find path -- and yet it's saving the image there anyway?

  - by Rob

  I have an issue where the local version of django is handling image upload as expected but my server is not. Note: I am using a Django Container on MediaTemple.net (grid server) Here is my code. def view_settings(request): <snip> if request.POST: success_msgs = () mForm = MainProfileForm(request.POST, request.FILES, instance = mProfile) pForm = ChangePasswordForm(request.POST) eForm = ChangeEmailForm(request.POST) if mForm.is_valid(): m = mForm.save(commit = False) if mForm.cleaned_data['avatar']: m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) m.save() success_msgs += ('profile pictured updated',) <snip> def upload_photo(data,saveLocation): savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, data.name) destination = open(savePath, 'wb+') for chunk in data.chunks(): destination.write(chunk) destination.close() return os.path.join(saveLocation, data.name) Here's where it gets whacky and I was hoping someone could shed a light on this error, because either a) it's the wrong error code, or b) something is happening with the file before it's completely handled. To recap, the file was actually uploaded to the server in the intended directory - and yet this err msg continues to persist.

• Why can't I pass an argument to create this window using wxpython?

  - by somefreakingguy

  I am trying to learn how to make a GUI in python! Following an online tutorial, I found that the following code 'works' in creating an empty window: import wx from sys import argv class bucky(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(300, 200)) if __name__=='__main__': app=wx.PySimpleApp() frame=bucky(parent=None,id=-1) frame.Show() app.MainLoop() That gives me a window, which is great. However, what if I want to get an argument passed onto the program to determine the window size? I thought something like this ought to do the trick: import wx from sys import argv script, x, y = argv class mywindow(wx.Frame): def __init__(self, parent, id): wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x, y)) if __name__=='__main__': app=wx.PySimpleApp() frame=mywindow(parent=None,id=-1) frame.Show() app.MainLoop() But, alas, that does not work! Nor does the raw_input() function pass on the value. I keep getting the following error: C:/Python26/pythonw.exe -u "C:/Documents and Settings/Owner/Desktop/wz.py" File "C:/Documents and Settings/Owner/Desktop/wz.py", line 8 wx.Frame.__init__(self, parent, id, 'Frame aka window', size=(x y)) ^ SyntaxError: invalid syntax Thanks for the help!

• Return a list of imported Python modules used in a script?

  - by Jono Bacon

  Hi All, I am writing a program that categorizes a list of Python files by which modules they import. As such I need to scan the collection of .py files ad return a list of which modules they import. As an example, if one of the files I import has the following lines: import os import sys, gtk I would like it to return: ["os", "sys", "gtk"] I played with modulefinder and wrote: from modulefinder import ModuleFinder finder = ModuleFinder() finder.run_script('testscript.py') print 'Loaded modules:' for name, mod in finder.modules.iteritems(): print '%s ' % name, but this returns more than just the modules used in the script. As an example in a script which merely has: import os print os.getenv('USERNAME') The modules returned from the ModuleFinder script return: tokenize heapq __future__ copy_reg sre_compile _collections cStringIO _sre functools random cPickle __builtin__ subprocess cmd gc __main__ operator array select _heapq _threading_local abc _bisect posixpath _random os2emxpath tempfile errno pprint binascii token sre_constants re _abcoll collections ntpath threading opcode _struct _warnings math shlex fcntl genericpath stat string warnings UserDict inspect repr struct sys pwd imp getopt readline copy bdb types strop _functools keyword thread StringIO bisect pickle signal traceback difflib marshal linecache itertools dummy_thread posix doctest unittest time sre_parse os pdb dis ...whereas I just want it to return 'os', as that was the module used in the script. Can anyone help me achieve this?

• Python 3.0 IDE - Komodo and Eclipse both flaky?

  - by victorhooi

  heya, I'm trying to find a decent IDE that supports Python 3.x, and offers code completion/in-built Pydocs viewer, Mercurial integration, and SSH/SFTP support. Anyhow, I'm trying Pydev, and I open up a .py file, it's in the Pydev perspective and the Run As doesn't offer any options. It does when you start a Pydev project, but I don't want to start a project just to edit one single Python script, lol, I want to just open a .py file and have It Just Work... Plan 2, I try Komodo 6 Alpha 2. I actually quite like Komodo, and it's nice and snappy, offers in-built Mercurial support, as well as in-built SSH support (although it lacks SSH HTTP Proxy support, which is slightly annoying). However, for some reason, this refuses to pick up Python 3. In Edit-Preferences-Languages, there's two option, one for Python and Python3, but the Python3 one refuses to work, with either the official Python.org binaries, or ActiveState's own ActivePython 3. Of course, I can set the "Python" interpreter to the 3.1 binary, but that's an ugly hack and breaks Python 2.x support. So, does anybody who uses an IDE for Python have any suggestions on either of these accounts, or can you recommend an alternate IDE for Python 3.0 development? Cheers, Victor

• Google App Engine Needs Index Error

  - by Andrew Johnson

  I am currently getting a needs index error on my app engine app: http://www.gaiagps.com/wiki/home. I believe this index should have been created automatically by my index.yaml file (see below). Googling a bit, I think I just need to wait for my index to be built. Is this correct, or do I need to do something manually? Is there some sort of index-building queue? My tables are very, very small right now. EDIT: I added the line "indexes:" to my app.yaml, and now app engine reports the index is building, so I think this is fixed. It's weird that this file was wrong considering I've never touched it. indexes: # AUTOGENERATED # This index.yaml is automatically updated whenever the dev_appserver # detects that a new type of query is run. If you want to manage the # index.yaml file manually, remove the above marker line (the line # saying "# AUTOGENERATED"). If you want to manage some indexes # manually, move them above the marker line. The index.yaml file is # automatically uploaded to the admin console when you next deploy # your application using appcfg.py. - kind: Revision properties: - name: name - name: created The app works on my dev server, but not in production. However, on my dev console, I have noticed this error (EDIT: THIS ERROR IS GONE NOW THAT I ADDED indexes: to the app.yaml file above): ERROR 2009-10-18 04:46:51,908 dev_appserver_index.py:176] Error parsing /gaiagps.com/index.yaml: 'NoneType' object is not callable in "<string>", line 13, column 3: - kind: Revision ^
