| # 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/␊ |
