svn_log
Returns the commit log messages of a repository URL
(PECL svn:0.1-0.2)
array svn_log ( string repos_url [, int revision_no] )
svn_log() returns the complete history of the item at the repository URL
repos_url, or the history of a specific revision
if revision_no is set. This function is equivalent
to svn log --verbose -r $revision_no $repos_url.
For repositories with large histories, the output may
be quite large (one array item for every revision of the item).
This function does not support the
--limit NUM flag, nor does it support revision
ranges (revision_no must be an integer).
Parameters
- repos_url
Repository URL of the item to retrieve log history from.
- revision_no
Revision number of the log to retrieve. Use
SVN_REVISON_HEADto retrieve the log for the most recent revision.
Return Values
On success, this function returns an array file listing in the format of:
[0] => Array, ordered most recent (highest) revision first
(
[rev] => integer revision number
[author] => string author name
[msg] => string log message
[date] => string date formatted per ISO 8601, i.e. date('c')
[paths] => Array, describing changed files
(
[0] => Array
(
[action] => string letter signifying change
[path] => absolute repository path of changed file
)
[1] => ...
)
)
[1] => ...The output will always be a numerically indexed array of arrays, even when there are none or only one log message(s).
The value of action is a subset of the
» status output
in the first column, where possible values are:
Table 316. Actions
| Letter | Description |
|---|---|
| M | Item/props was modified |
| A | Item was added |
| D | Item was deleted |
| R | Item was replaced |
If no changes were made to the item, an empty array is returned.
Notes
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.
Examples
Example 2498. svn_log() example
<?php
print_r( svn_log('http://www.example.com/', 23) );
?>The above example will output something similar to:
Array
(
[0] => Array
(
[rev] => 23
[author] => 'joe'
[msg] => 'Add cheese and salami to our sandwich.'
[date] => '2007-04-06T16:00:27-04:00'
[paths] => Array
(
[0] => Array
(
[action] => 'M'
[path] => '/sandwich.txt'
)
)
)
)
Example 2499. Simulating --limit with svn and svn_log()
This sample function simulates the --limit switch
by using the SVN executable to return a list of revisions, which
are then losslessly accessed using svn_log().
This function will perform a total of limit + 1 requests: the first request to pull the required revisions, and each one after to retrieve the log item for that request.
<?php
/**
* Retrieves the last $limit log entries.
* @param $repos_url Repository URL of item to get logs for
* @param $limit Integer limit of items
*/
function svn_log_limit($repos_url, $limit) {
$limit = (int) $limit;
if ($limit <= 0) return array();
// -q flag used to prevent server from sending log messages
$output = shell_exec("svn log -q --limit $limit $repos_url");
preg_match_all('/^r(\d+) /m', $output, $matches);
$ret = array();
foreach ($matches[1] as $rev) {
$log = svn_log($repos_url, (int) $rev);
$ret[] = $log[0]; // log is only one item long
}
return $ret;
}
?>
