• Does Django tests run slower on the mac compared to linux?

  - by Thierry Lam

  I'm currently developing my Django projects on both: Mac OS X 10.5, 32 bit Ubuntu Server 9.10 64 bits (1 CPU, 512MB RAM) Both of the above OS are using: Python 2.6.4 Django 1.1.1 MySQL 5.1 Running 12 tests for one of my application take: Mac: 57.513s Linux: 30.935s EDIT: Mac Hardware Spec: MacBook Pro 2.2 GHz Intel Core 2 Duo 3GB RAM I'm running the Ubuntu OS on the same mac above through VMware Fusion 2.0.6. You might argue that Ubuntu Server 64 bits is faster but I have observed a similar speed difference on Ubuntu 8.10 32 bits desktop edition. Even if I turn off my linux VM and other mac applications, I still experience the slowness. Has anyone else experienced this Django test speed difference across those two OS?

• cd Terminal at a given directory after running a Python script?

  - by Dave Everitt

  I'm working on a simple Python script that can use subprocess and/or os to execute some commands, which is working fine. However, when the script exits I'd like to cd the actual Terminal (in this case OS X) so on exit, the new files are ready to use in the directory where the have been created. All the following (subprocess.Popen, os.system, os.chdir) can do what I want from within the script (i.e. they execute stuff in the target directory) but on exit leave the Terminal at the script's own directory, not the target directory. I'd like to avoid writing a shell script to temporary file just to achieve this, if this is at all possible anyway?

• Weird exception: Cannot cast String to Boolean when using getBoolean

  - by La bla bla

  I'm getting a very weird error. I have 2 activities. On both I'm getting the SharedPreferences using MODE_PRIVATE (if it matters) by sp = getPreferences(MODE_PRIVATE); on each activity's onCreate() I'm calling sp.getBoolean(IntroActivity.SHOW_INTRO, true) On the IntroActivity this works fine. But when I'm trying in the main activity, I'm getting this 10-12 04:55:23.208: E/AndroidRuntime(11668): FATAL EXCEPTION: main 10-12 04:55:23.208: E/AndroidRuntime(11668): java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.app.SharedPreferencesImpl.getBoolean(SharedPreferencesImpl.java:242) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.lablabla.parkme.ParkMeActivity$2.onClick(ParkMeActivity.java:194) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.view.View.performClick(View.java:4084) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.view.View$PerformClick.run(View.java:16966) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Handler.handleCallback(Handler.java:615) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Handler.dispatchMessage(Handler.java:92) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.os.Looper.loop(Looper.java:137) 10-12 04:55:23.208: E/AndroidRuntime(11668): at android.app.ActivityThread.main(ActivityThread.java:4745) 10-12 04:55:23.208: E/AndroidRuntime(11668): at java.lang.reflect.Method.invokeNative(Native Method) 10-12 04:55:23.208: E/AndroidRuntime(11668): at java.lang.reflect.Method.invoke(Method.java:511) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 10-12 04:55:23.208: E/AndroidRuntime(11668): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-12 04:55:23.208: E/AndroidRuntime(11668): at dalvik.system.NativeStart.main(Native Method) I made sure that I'm not putting a String somewhere in the middle with that same key Any ideas?

• execution of instructions in a child process

  - by ness kh

  I want to exit from a child process when the execution of os.system(comm) will be executed. My code is: pid = os.fork() if pid == 0: #instruction else: comm = "python file.py" os.system(comm) os.exit(error) Now, my file file.py contains a loop, and I can get out from it only if a condition is satisfied. But, even when the condition is not satisfied, the program exits from the loop and displays the message error. Also it doesn't execute the rest of instructions in file.py. file.py is : while 1: if(condition): break # rest of instructions

• Fetching JSON object from Servlet Java

  - by ChrisA

  I want to create an application that will fetch a JSON object from a servlet to deserialize it, and then use its variables to do other things. My servlet has the following code in the doPost: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ObjectOutputStream os; os = new ObjectOutputStream(response.getOutputStream()); String s = new String("A String"); Gson gson = new Gson(); String gsonObject= gson.toJson(s); os.writeObject(gsonObject); os.close(); } Now, while the servlet is running, I can access it via a browser, if I post same code in the doGet method, that would download a servlet file, which is not what I want. What should I use in my second application that would connect to the servlet, fetch the object, so that I can manipulate it later? Thanks in advance.

• Is there a way to convert code to a string and vice versa in Python?

  - by Dragos Toader

  The original question was: Is there a way to declare macros in Python as they are declared in C: #define OBJWITHSIZE(_x) (sizeof _x)/(sizeof _x[0]) Here's what I'm trying to find out: Is there a way to avoid code duplication in Python? In one part of a program I'm writing, I have a function: def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) In another part, I've got this code embedded in a string that will later be output to a python file that will itself be run: """ def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) """ How can I build a "macro" that will avoid this duplication?

• Why is a non-blocking TCP connect() occasionally so slow on Linux?

  - by pts

  I was trying to measure the speed of a TCP server I'm writing, and I've noticed that there might be a fundamental problem of measuring the speed of the connect() calls: if I connect in a non-blocking way, connect() operations become very slow after a few seconds. Here is the example code in Python: #! /usr/bin/python2.4 import errno import os import select import socket import sys def NonBlockingConnect(sock, addr): while True: try: return sock.connect(addr) except socket.error, e: if e.args[0] not in (errno.EINPROGRESS, errno.EALREADY): raise os.write(2, '^') if not select.select((), (sock,), (), 0.5)[1]: os.write(2, 'P') def InfiniteClient(addr): while True: sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) sock.setblocking(0) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) # sock.connect(addr) NonBlockingConnect(sock, addr) sock.close() os.write(2, '.') def InfiniteServer(server_socket): while True: sock, addr = server_socket.accept() sock.close() server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0) server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) server_socket.bind(('127.0.0.1', 45454)) server_socket.listen(128) if os.fork(): # Parent. InfiniteServer(server_socket) else: addr = server_socket.getsockname() server_socket.close() InfiniteClient(addr) With NonBlockingConnect, most connect() operations are fast, but in every few seconds there happens to be one connect() operation which takes at least 2 seconds (as indicated by 5 consecutive P letters on the output). By using sock.connect instead of NonBlockingConnect all connect operations seem to be fast. How is it possible to get rid of these slow connect()s? I'm running Ubuntu Karmic desktop with the standard PAE kernel: Linux narancs 2.6.31-20-generic-pae #57-Ubuntu SMP Mon Feb 8 10:23:59 UTC 2010 i686 GNU/Linux

• Cant fetch production db results using Google app engine remote_api

• How can I link two Java serialised objects back together?

  - by Kidburla

  Sometimes (quite a lot, actually) we get a situation in Java where two objects are pointing to the same thing. Now if we serialise these separately it is quite appropriate that the serialised forms have separate copies of the object as it should be possible to open one without the other. However if we now deserialise them both, we find that they are still separated. Is there any way to link them back together? Example follows. public class Example { private static class ContainerClass implements java.io.Serializable { private ReferencedClass obj; public ReferencedClass get() { return obj; } public void set(ReferencedClass obj) { this.obj = obj; } } private static class ReferencedClass implements java.io.Serializable { private int i = 0; public int get() { return i; } public void set(int i) { this.i = i; } } public static void main(String[] args) throws Exception { //Initialise the classes ContainerClass test1 = new ContainerClass(); ContainerClass test2 = new ContainerClass(); ReferencedClass ref = new ReferencedClass(); //Make both container class point to the same reference test1.set(ref); test2.set(ref); //This does what we expect: setting the integer in one (way of accessing the) referenced class sets it in the other one test1.get().set(1234); System.out.println(Integer.toString(test2.get().get())); //Now serialise the container classes java.io.ObjectOutputStream os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test1.ser")); os.writeObject(test1); os.close(); os = new java.io.ObjectOutputStream(new java.io.FileOutputStream("C:\\Users\\Public\\test2.ser")); os.writeObject(test2); os.close(); //And deserialise them java.io.ObjectInputStream is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test1.ser")); ContainerClass test3 = (ContainerClass)is.readObject(); is.close(); is = new java.io.ObjectInputStream(new java.io.FileInputStream("C:\\Users\\Public\\test2.ser")); ContainerClass test4 = (ContainerClass)is.readObject(); is.close(); //We expect the same thing as before, and would expect a result of 4321, but this doesn't happen as the referenced objects are now separate instances test3.get().set(4321); System.out.println(Integer.toString(test4.get().get())); } }

• deleting unaccessed files using python

  - by damon

  My django app parses some files uploaded by the user.It is possible that the file uploaded by the user may remain in the server for a long time ,without it being parsed by the app.This can increase in size if a lot of users upload a lot of files. I need to delete those files not recently parsed by the app -say not accessed for last 24 hours.I tried like this import os import time dirname = MEDIA_ROOT+my_folder filenames = os.listdir(dirname) filenames = [os.path.join(dirname,filename) for filename in filenames] for filename in filenames: last_access = os.stat(filename).st_atime #secs since epoch rtime = time.asctime(time.localtime(last_access)) print filename+'----'+rtime This shows the last accessed times for each file..But I am not sure how I can test if the file access time was within the last 24 hours..Can somebody help me out?

• How to select random image of specific size using Django / Python?

  - by Jonathan

  I've been using this little snippet to select random images. However I would like to change it to select only images of a certain size. I'm running into trouble checking against image size. If I use get_image_dimensions() I need to use a conditional statement, which then requires that I allow exceptions. So, I guess I need some pointers on just limiting by image dimensions. Thanks. import os import random import posixpath from django import template from django.conf import settings register = template.Library() def is_image_file(filename): """Does `filename` appear to be an image file?""" img_types = [".jpg", ".jpeg", ".png", ".gif"] ext = os.path.splitext(filename)[1] return ext in img_types @register.simple_tag def random_image(path): """ Select a random image file from the provided directory and return its href. `path` should be relative to MEDIA_ROOT.

• Why should I install Python packages into `~/.local`?

  - by Matthew Rankin

  Background I don't develop using OS X's system provided Python versions (on OS X 10.6 that's Python 2.5.4 and 2.6.1). I don't install anything in the site-packages directory for the OS provided versions of Python. (The only exception is Mercurial installed from a binary package, which installs two packages in the Python 2.6.1 site-packages directory.) I installed three versions of Python, all using the Mac OS X installer disk image: Python 2.6.6 Python 2.7 Python 3.1.2 I don't like polluting the site-packages directory for my Python installations. So I only install the following five base packages in the site-packages directory. For the actual method/commands used to install these, see SO Question 4324558. setuptools/ez_setup distribute pip virtualenv virtualenvwrapper All other packages are installed in virtualenvs. I am the only user of this MacBook. Questions Given the above background, why should I install the five base packages in ~/.local? Since I'm installing these base packages into the site-packages directories of Python distributions that I've installed, I'm isolated from the OS X's Python distributions. Using this method, should I be concerned about Glyph's comment that other things could potentially break (see his comment below)? Again, I'm only interested in where to install those five base packages. Related Questions/Info I'm asking because of Glyph's comment to my answer to SO question 4314376, which stated: NO. NEVER EVER do sudo python setup.py install whatever. Write a ~/.pydistutils.cfg that puts your pip installation into ~/.local or something. Especially files named ez_setup.py tend to suck down newer versions of things like setuptools and easy_install, which can potentially break other things on your operating system. Previously, I asked What's the proper way to install pip, virtualenv, and distribute for Python?. However, no one answered the "why" of using ~/.local.

• How to write a list to a text file in the correct format

• SQL Server 2008 R2 Enterprise won't install on Windows 2008 R2 Enterprise

  I've been trying to install SQL Server on a new Windows Server 2008. I have tried everything but I haven't been able to narrow down the problem. When the installation fails I get " Exit code (Decimal): -2068643839". The problem with this is that according to Microsoft this is a generic error code. I follow their guide to look into the detail.txt inside C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log\ But I can't find something that specifies the exact error. Any suggestions ? Thanks in advanced. I uploaded to detail.txt to http://www.megaupload.com/?d=0MV46SZH because it is to big to paste here.

• Running two wsgi applications on the same server gdal org exception with apache2/modwsgi

  - by monkut

  I'm trying to run two wsgi applications, one django and the other tilestache using the same server. The tilestache server accesses the db via django to query the db. In the process of serving tiles it performs a transform on the incoming bbox, and in this process hit's the following error. The transform works without error for the specific bbox polygon when run manually from the python shell: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 325, in __call__ mimetype, content = requestHandler(self.config, environ['PATH_INFO'], environ['QUERY_STRING']) File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 231, in requestHandler mimetype, content = getTile(layer, coord, extension) File "/usr/lib/python2.7/dist-packages/TileStache/__init__.py", line 84, in getTile tile = layer.render(coord, format) File "/usr/lib/python2.7/dist-packages/TileStache/Core.py", line 295, in render tile = provider.renderArea(width, height, srs, xmin, ymin, xmax, ymax, coord.zoom) File "/var/www/tileserver/providers.py", line 59, in renderArea bbox.transform(METERS_SRID) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/geos/geometry.py", line 520, in transform g = gdal.OGRGeometry(self.wkb, srid) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geometries.py", line 131, in __init__ self.__class__ = GEO_CLASSES[self.geom_type.num] File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geometries.py", line 245, in geom_type return OGRGeomType(capi.get_geom_type(self.ptr)) File "/usr/local/lib/python2.7/dist-packages/django/contrib/gis/gdal/geomtype.py", line 43, in __init__ raise OGRException('Invalid OGR Integer Type: %d' % type_input) OGRException: Invalid OGR Integer Type: 1987180391 I think I've hit the non thread safe issue with GDAL, metioned on the django site. Is there a way I could configure this so that it would work? Apache Version: Apache/2.2.22 (Ubuntu) mod_wsgi/3.3 Python/2.7.3 configured Apache apache2/sites-available/default: <VirtualHost *:80> ServerAdmin ironman@localhost DocumentRoot /var/www/bin LogLevel warn WSGIDaemonProcess lbs processes=2 maximum-requests=500 threads=1 WSGIProcessGroup lbs WSGIScriptAlias / /var/www/bin/apache/django.wsgi Alias /static /var/www/lbs/static/ </VirtualHost> <VirtualHost *:8080> ServerAdmin ironman@localhost DocumentRoot /var/www/bin LogLevel warn WSGIDaemonProcess tilestache processes=1 maximum-requests=500 threads=1 WSGIProcessGroup tilestache WSGIScriptAlias / /var/www/bin/tileserver/tilestache.wsgi </VirtualHost> Django Version: 1.4 httpd.conf: Listen 8080 NameVirtualHost *:8080 UPDATE I've added the a test.wsgi script to determine if the GLOBAL interpreter setting is correct, as mentioned by graham and described here: http://code.google.com/p/modwsgi/wiki/CheckingYourInstallation#Sub_Interpreter_Being_Used It seems to show the expected result: [Tue Aug 14 10:32:01 2012] [notice] Apache/2.2.22 (Ubuntu) mod_wsgi/3.3 Python/2.7.3 configured -- resuming normal operations [Tue Aug 14 10:32:01 2012] [info] mod_wsgi (pid=29891): Attach interpreter ''. I've worked around the issue for now by changing the srs used in the db so that the transform is unnecessary in tilestache app. I don't understand why the transform() method, when called in the django app works, but then in the tilestache app fails. tilestache.wsgi #!/usr/bin/python import os import time import sys import TileStache current_dir = os.path.abspath(os.path.dirname(__file__)) project_dir = os.path.realpath(os.path.join(current_dir, "..", "..")) sys.path.append(project_dir) sys.path.append(current_dir) os.environ['DJANGO_SETTINGS_MODULE'] = 'bin.settings' sys.stdout = sys.stderr # wait for the apache django lbs server to start up, # --> in order to retrieve the tilestache cfg time.sleep(2) tilestache_config_url = "http://127.0.0.1/tilestache/config/" application = TileStache.WSGITileServer(tilestache_config_url) UPDATE 2 So it turned out I did need to use a projection other than the google (900913) one in the db. So my previous workaround failed. While I'd like to fix this issue, I decided to work around the issue this type by making a django view that performs the transform needed. So now tilestache requests the data through the django app and not internally.

• Error installing pkgconfig via macports

  - by Greg K

  I installed Macports 1.8.2 from a DMG. That seemed to install fine. I ran sudo port selfupdate to make sure my ports tree was current. I then tried to install bindfs as I want to mount some directories in my OS X file system (like you can do with mount --bind in linux). pkgconfig and macfuse are two dependencies of bindfs. I had trouble installing bindfs due to errors installing pkgconfig, so I tried to just install pkgconfig, here's the debug output from sudo port install pkgconfig: $ sudo port -d install pkgconfig DEBUG: Found port in file:///opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/pkgconfig DEBUG: Changing to port directory: /opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/pkgconfig DEBUG: OS Platform: darwin DEBUG: OS Version: 10.3.0 DEBUG: Mac OS X Version: 10.6 DEBUG: System Arch: i386 DEBUG: setting option os.universal_supported to yes DEBUG: org.macports.load registered provides 'load', a pre-existing procedure.
