| 3 | # PRE-REVPROP-CHANGE HOOK
|
|---|
| 4 | #
|
|---|
| 5 | # The pre-revprop-change hook is invoked before a revision property
|
|---|
| 6 | # is added, modified or deleted. Subversion runs this hook by invoking
|
|---|
| 7 | # a program (script, executable, binary, etc.) named 'pre-revprop-change'
|
|---|
| 8 | # (for which this file is a template), with the following ordered
|
|---|
| 9 | # arguments:
|
|---|
| 10 | #
|
|---|
| 11 | # [1] REPOS-PATH (the path to this repository)
|
|---|
| 12 | # [2] REVISION (the revision being tweaked)
|
|---|
| 13 | # [3] USER (the username of the person tweaking the property)
|
|---|
| 14 | # [4] PROPNAME (the property being set on the revision)
|
|---|
| 15 | # [5] ACTION (the property is being 'A'dded, 'M'odified, or 'D'eleted)
|
|---|
| 16 | #
|
|---|
| 17 | # [STDIN] PROPVAL ** the new property value is passed via STDIN.
|
|---|
| 18 | #
|
|---|
| 19 | # If the hook program exits with success, the propchange happens; but
|
|---|
| 20 | # if it exits with failure (non-zero), the propchange doesn't happen.
|
|---|
| 21 | # The hook program can use the 'svnlook' utility to examine the
|
|---|
| 22 | # existing value of the revision property.
|
|---|
| 23 | #
|
|---|
| 24 | # WARNING: unlike other hooks, this hook MUST exist for revision
|
|---|
| 25 | # properties to be changed. If the hook does not exist, Subversion
|
|---|
| 26 | # will behave as if the hook were present, but failed. The reason
|
|---|
| 27 | # for this is that revision properties are UNVERSIONED, meaning that
|
|---|
| 28 | # a successful propchange is destructive; the old value is gone
|
|---|
| 29 | # forever. We recommend the hook back up the old value somewhere.
|
|---|
| 30 | #
|
|---|
| 31 | # On a Unix system, the normal procedure is to have 'pre-revprop-change'
|
|---|
| 32 | # invoke other programs to do the real work, though it may do the
|
|---|
| 33 | # work itself too.
|
|---|
| 34 | #
|
|---|
| 35 | # Note that 'pre-revprop-change' 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-revprop-change.bat' or 'pre-revprop-change.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.
|
|---|
| 51 | # For more examples and pre-written hooks, see those in
|
|---|
| 52 | # /usr/share/subversion/hook-scripts, and in the repository at
|
|---|
| 53 | # http://svn.apache.org/repos/asf/subversion/trunk/tools/hook-scripts/ and
|
|---|
| 54 | # http://svn.apache.org/repos/asf/subversion/trunk/contrib/hook-scripts/
