Using python scripts in subversion hooks on windows

Question

My main goal is to get this up and running.

My hook gets called when I do the commit with Tortoise SVN, but it always exits when I get to this line: Python "%~dp0trac-post-commit-hook.py" -p "%TRAC_ENV%" -r "%REV%" || EXIT 5

If I try and replace the call to the python script with any simple Python script it still doesn't work so I'm assuming it is a problem with the call to Python and not the script itself.

I have tried setting the PYTHON_PATH variable and also set %PATH% to include Python.

I have trac up and running so Python is working on the server itself.

Here is some background info:

• Python is installed on Windows server and script is called from local machine so

  IF NOT EXIST %TRAC_ENV% EXIT 3

  and

  SET PYTHON_PATH=X:\Python26 IF NOT EXIST %PYTHON_PATH% EXIT 4

fail unless I point set them to the mapped network drive (That is point them at X and Y drives not C and E drives)

• Python scripts can be called anywhere from the command line from the server regardless of the drive so the PATH variable should be set correctly

Appears to be an issue with calling python scripts externally, but not sure how I go about changing the permissions for this.

Thanks in advance.

Take the following things into account:

• network drive mappings and subst mappings are user specific. Make sure the drives exist for the user account under which the svn server is running.
• subversion hook scripts are run without any environment variables being set for security reasons, not even %path%. Call the python executable with an absolute path, e.g. c:\python25\python.exe.
