python - Bitnami Trac 0.11.6 SVN Post commit hooks failing

问题描述:

Beating my head against a wall here for a day trying to get post commit hooks work so I can add refs/ close tickets in trac from an SVN commit.

I used the bitnami trac stack to install and am fairly happy with the way its setup.

Every commit though gives the error

svn: MERGE of "/svn/Project": 200 OK (http://10.0.0.204)

I can see from various posts that this is down to the post commit hook failing but thesvn commit succeding. I've used the standard script from the edgewall site and my files look like the below (sorry for the length these make the post but I guess the more info the better..)

post-commit.cmd

@ECHO OFF

:: POST-COMMIT HOOK

::

:: The post-commit hook is invoked after a commit. Subversion runs

:: this hook by invoking a program (script, executable, binary, etc.)

:: named 'post-commit' (for which this file is a template) with the

:: following ordered arguments:

::

:: [1] REPOS-PATH (the path to this repository)

:: [2] REV (the number of the revision just committed)

::

:: The default working directory for the invocation is undefined, so

:: the program should set one explicitly if it cares.

::

:: Because the commit has already completed and cannot be undone,

:: the exit code of the hook program is ignored. The hook program

:: can use the 'svnlook' utility to help it examine the

:: newly-committed tree.

::

:: On a Unix system, the normal procedure is to have 'post-commit'

:: invoke other programs to do the real work, though it may do the

:: work itself too.

::

:: Note that 'post-commit' must be executable by the user(s) who will

:: invoke it (typically the user httpd runs as), and that user must

:: have filesystem-level permission to access the repository.

::

:: On a Windows system, you should name the hook program

:: 'post-commit.bat' or 'post-commit.exe',

:: but the basic idea is the same.

::

:: The hook program typically does not inherit the environment of

:: its parent process. For example, a common problem is for the

:: PATH environment variable to not be set to its usual value, so

:: that subprograms fail to launch unless invoked via absolute path.

:: If you're having unexpected problems with a hook program, the

:: culprit may be unusual (or missing) environment variables.

::

:: Here is an example hook script, for a Unix /bin/sh interpreter.

:: For more examples and pre-written hooks, see those in

:: the Subversion repository at

:: http://svn.collab.net/repos/svn/trunk/tools/hook-scripts/ and

:: http://svn.collab.net/repos/svn/trunk/contrib/hook-scripts/

setlocal

:: Debugging setup

:: 1. Make a copy of this file.

:: 2. Enable the command below to call the copied file.

:: 3. Remove all other commands

::call %~dp0post-commit-run.cmd %* > %1/hooks/post-commit.log 2>&1

:: Call Trac post-commit hook

call %~dp0trac-post-commit-hook.cmd %* || exit 1

trac-post-commit-hook.cmd

@ECHO OFF

::

:: Trac post-commit-hook script for Windows

::

:: Contributed by markus, modified by cboos.

:: Usage:

::

:: 1) Insert the following line in your post-commit.bat script

::

:: call %~dp0\trac-post-commit-hook.cmd %1 %2

::

:: 2) Check the 'Modify paths' section below, be sure to set at least TRAC_ENV

setlocal

:: ----------------------------------------------------------

:: Modify paths here:

:: -- this one *must* be set

SET TRAC_ENV=E:\Trac\Project\Project

:: -- set if Python is not in the system path

:: SET PYTHON_PATH=

:: -- set to the folder containing trac/ if installed in a non-standard location

:: SET TRAC_PATH= "C:\Program Files\Bitnami Trac Stack\"

:: ----------------------------------------------------------

:: Do not execute hook if trac environment does not exist

IF NOT EXIST %TRAC_ENV% GOTO :EOF

set PATH=%PYTHON_PATH%;%PATH%

set PYTHONPATH=%TRAC_PATH%;%PYTHONPATH%

SET REV=%2

:: Resolve ticket references (fixes, closes, refs, etc.)

Python "%~dp0trac-post-commit-resolve-ticket-ref.py" -p "%TRAC_ENV%" -r "%REV%"

endlocal

haven't removed the comments from the trac path there but don't think it should be needed. Finally the script from edgewall..

# This Subversion post-commit hook script is meant to interface to the

# Trac (http://www.edgewall.com/products/trac/) issue tracking/wiki/etc

# system.

#

# It should be called from the 'post-commit' script in Subversion, such as

# via:

#

# REPOS="$1"

# REV="$2"

# TRAC_ENV="/path/to/tracenv"

#

# /usr/bin/python /usr/local/src/trac/contrib/trac-post-commit-hook \

# -p "$TRAC_ENV" -r "$REV"

#

# (all the other arguments are now deprecated and not needed anymore)

#

# It searches commit messages for text in the form of:

# command #1

# command #1, #2

# command #1 & #2

# command #1 and #2

#

# Instead of the short-hand syntax "#1", "ticket:1" can be used as well, e.g.:

# command ticket:1

# command ticket:1, ticket:2

# command ticket:1 & ticket:2

# command ticket:1 and ticket:2

#

# In addition, the ':' character can be omitted and issue or bug can be used

# instead of ticket.

#

# You can have more than one command in a message. The following commands

# are supported. There is more than one spelling for each command, to make

# this as user-friendly as possible.

#

# close, closed, closes, fix, fixed, fixes

# The specified issue numbers are closed with the contents of this

# commit message being added to it.

# references, refs, addresses, re, see

# The specified issue numbers are left in their current status, but

# the contents of this commit message are added to their notes.

#

# A fairly complicated example of what you can do is with a commit message

# of:

#

# Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12.

#

# This will close #10 and #12, and add a note to #12.

If anyone can see why the python script is failing in someway it would really help me out.

Thanks...

Traced out the command and got the following in the log file.

trac.core.TracError: Unsupported version control system "svn": "DLL load failed with error code 182"

As I had this working at some point before messing with SSL I'm wondering if something has been moved or deleted in error... any clues?

网友答案:

Imports were working from command line. The problem turned out to be the path. It wasn't working setting the python path in the script file or as an system variable as PYTHON_PATH or PYTHONPATH. It would run the python command correctly like that but would then not use the correct svn bindings. Adding the python dir location to the system Path worked. thanks anyway!
