# PRE-COMMIT HOOK
|
| 4 |
|
|
#
|
| 5 |
|
|
# The pre-commit hook is invoked before a Subversion txn is
|
| 6 |
|
|
# committed. Subversion runs this hook by invoking a program
|
| 7 |
|
|
# (script, executable, binary, etc.) named 'pre-commit' (for which
|
| 8 |
|
|
# this file is a template), with the following ordered arguments:
|
| 9 |
|
|
#
|
| 10 |
|
|
# [1] REPOS-PATH (the path to this repository)
|
| 11 |
|
|
# [2] TXN-NAME (the name of the txn about to be committed)
|
| 12 |
|
|
#
|
| 13 |
|
|
# The default working directory for the invocation is undefined, so
|
| 14 |
|
|
# the program should set one explicitly if it cares.
|
| 15 |
|
|
#
|
| 16 |
|
|
# If the hook program exits with success, the txn is committed; but
|
| 17 |
|
|
# if it exits with failure (non-zero), the txn is aborted, no commit
|
| 18 |
|
|
# takes place, and STDERR is returned to the client. The hook
|
| 19 |
|
|
# program can use the 'svnlook' utility to help it examine the txn.
|
| 20 |
|
|
#
|
| 21 |
|
|
# On a Unix system, the normal procedure is to have 'pre-commit'
|
| 22 |
|
|
# invoke other programs to do the real work, though it may do the
|
| 23 |
|
|
# work itself too.
|
| 24 |
|
|
#
|
| 25 |
|
|
# *** NOTE: THE HOOK PROGRAM MUST NOT MODIFY THE TXN, EXCEPT ***
|
| 26 |
|
|
# *** FOR REVISION PROPERTIES (like svn:log or svn:author). ***
|
| 27 |
|
|
#
|
| 28 |
|
|
# This is why we recommend using the read-only 'svnlook' utility.
|
| 29 |
|
|
# In the future, Subversion may enforce the rule that pre-commit
|
| 30 |
|
|
# hooks should not modify the versioned data in txns, or else come
|
| 31 |
|
|
# up with a mechanism to make it safe to do so (by informing the
|
| 32 |
|
|
# committing client of the changes). However, right now neither
|
| 33 |
|
|
# mechanism is implemented, so hook writers just have to be careful.
|
| 34 |
|
|
#
|
| 35 |
|
|
# Note that 'pre-commit' must be executable by the user(s) who will
|
| 36 |
|
|
# invoke it (typically the user httpd runs as), and that user must
|
| 37 |
|
|
# have filesystem-level permission to access the repository.
|
| 38 |
|
|
#
|
| 39 |
|
|
# On a Windows system, you should name the hook program
|
| 40 |
|
|
# 'pre-commit.bat' or 'pre-commit.exe',
|
| 41 |
|
|
# but the basic idea is the same.
|
| 42 |
|
|
#
|
| 43 |
|
|
# The hook program typically does not inherit the environment of
|
| 44 |
|
|
# its parent process. For example, a common problem is for the
|
| 45 |
|
|
# PATH environment variable to not be set to its usual value, so
|
| 46 |
|
|
# that subprograms fail to launch unless invoked via absolute path.
|
| 47 |
|
|
# If you're having unexpected problems with a hook program, the
|
| 48 |
|
|
# culprit may be unusual (or missing) environment variables.
|
| 49 |
|
|
#
|
| 50 |
|
|
# Here is an example hook script, for a Unix /bin/sh interpreter.# For more examples and pre-written hooks, see those in
|
| 51 |
|
|
# the Subversion repository at
|
| 52 |
|
|
# http://svn.collab.net/repos/svn/trunk/tools/hook-scripts/ and
|
| 53 |
|
|
# http://svn.collab.net/repos/svn/trunk/contrib/hook-scripts/
