 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] REV          (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 # the Subversion 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/
