# PRE-COMMIT HOOK␊ |
#␊ |
# The pre-commit hook is invoked before a Subversion txn is␊ |
# committed. Subversion runs this hook by invoking a program␊ |
# (script, executable, binary, etc.) named 'pre-commit' (for which␊ |
# this file is a template), with the following ordered arguments:␊ |
#␊ |
# [1] REPOS-PATH (the path to this repository)␊ |
# [2] TXN-NAME (the name of the txn about to be committed)␊ |
#␊ |
# [STDIN] LOCK-TOKENS ** the lock tokens are passed via STDIN.␊ |
#␊ |
# If STDIN contains the line "LOCK-TOKENS:\n" (the "\n" denotes a␊ |
# single newline), the lines following it are the lock tokens for␊ |
# this commit. The end of the list is marked by a line containing␊ |
# only a newline character.␊ |
#␊ |
# Each lock token line consists of a URI-escaped path, followed␊ |
# by the separator character '|', followed by the lock token string,␊ |
# followed by a newline.␊ |
#␊ |
# The default working directory for the invocation is undefined, so␊ |
# the program should set one explicitly if it cares.␊ |
#␊ |
# If the hook program exits with success, the txn is committed; but␊ |
# if it exits with failure (non-zero), the txn is aborted, no commit␊ |
# takes place, and STDERR is returned to the client. The hook␊ |
# program can use the 'svnlook' utility to help it examine the txn.␊ |
#␊ |
# On a Unix system, the normal procedure is to have 'pre-commit'␊ |
# invoke other programs to do the real work, though it may do the␊ |
# work itself too.␊ |
#␊ |
# *** NOTE: THE HOOK PROGRAM MUST NOT MODIFY THE TXN, EXCEPT ***␊ |
# *** FOR REVISION PROPERTIES (like svn:log or svn:author). ***␊ |
#␊ |
# This is why we recommend using the read-only 'svnlook' utility.␊ |
# In the future, Subversion may enforce the rule that pre-commit␊ |
# hooks should not modify the versioned data in txns, or else come␊ |
# up with a mechanism to make it safe to do so (by informing the␊ |
# committing client of the changes). However, right now neither␊ |
# mechanism is implemented, so hook writers just have to be careful.␊ |
#␊ |
# Note that 'pre-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␊ |
# 'pre-commit.bat' or 'pre-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␊ |
# /usr/share/subversion/hook-scripts, and in the repository at␊ |
# http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and␊ |
# http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/␊ |
