# PRE-REVPROP-CHANGE HOOK # # The pre-revprop-change hook is invoked before a revision property # is added, modified or deleted. Subversion runs this hook by invoking # a program (script, executable, binary, etc.) named 'pre-revprop-change' # (for which this file is a template), with the following ordered # arguments: # # [1] REPOS-PATH (the path to this repository) # [2] REVISION (the revision being tweaked) # [3] USER (the username of the person tweaking the property) # [4] PROPNAME (the property being set on the revision) # [5] ACTION (the property is being 'A'dded, 'M'odified, or 'D'eleted) # # [STDIN] PROPVAL ** the new property value is passed via STDIN. # # If the hook program exits with success, the propchange happens; but # if it exits with failure (non-zero), the propchange doesn't happen. # The hook program can use the 'svnlook' utility to examine the # existing value of the revision property. # # WARNING: unlike other hooks, this hook MUST exist for revision # properties to be changed. If the hook does not exist, Subversion # will behave as if the hook were present, but failed. The reason # for this is that revision properties are UNVERSIONED, meaning that # a successful propchange is destructive; the old value is gone # forever. We recommend the hook back up the old value somewhere. # # On a Unix system, the normal procedure is to have 'pre-revprop-change' # invoke other programs to do the real work, though it may do the # work itself too. # # Note that 'pre-revprop-change' 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-revprop-change.bat' or 'pre-revprop-change.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.collab.net/repos/svn/trunk/tools/hook-scripts/ and # http://svn.collab.net/repos/svn/trunk/contrib/hook-scripts/
