(PECL svn:0.1-0.2)
svn_diff — Recursively diffs two paths
Recursively diffs two paths, path1 and path2.
Note: This is not a general-purpose diff utility. Only local files that are versioned may be diffed: other files will fail.
First path to diff. This can be a URL to a file/directory in an SVN repository or a local file/directory path.
Note: Les chemins relatifs peuvent être résolus si le dossier de travail courant est l'un de ceux qui contiennent le binaire PHP. Pour utiliser le dossier de travail, utilisez la fonction realpath(), ou l'instruction dirname(__FILE__).
If a local file path has only backslashes and no forward slashes, this extension will fail to find the path. Always replace all backslashes with forward slashes when using this function.
First path's revision number. Use SVN_REVISON_HEAD to specify the most recent revision.
Second path to diff. See path1 for description.
Second path's revision number. See rev2 for description.
Returns an array-list consisting of two streams: the first is the diff output and the second contains error stream output. The streams can be read using fread(). Returns FALSE or NULL on error.
The diff output will, by default, be in the form of Subversion's custom unified diff format, but an » external diff engine may be used depending on Subversion's configuration.
Cette fonction est EXPERIMENTALE. Cela signifie que le comportement de cette fonction, son nom et, concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS ! Soyez-en conscient, et utilisez cette fonction à vos risques et périls.
Exemple 2670. Basic example
This example demonstrates the basic usage of this function, and the retrieval of contents from the stream:
<?php
list($diff, $errors) = svn_diff(
'http://www.example.com/svnroot/trunk/foo', SVN_REVISION_HEAD,
'http://www.example.com/svnroot/branches/dev/foo', SVN_REVISION_HEAD
);
if (!$diff) exit;
$contents = '';
while (!feof($diff)) {
$contents .= fread($diff, 8192);
}
fclose($diff);
fclose($errors);
var_dump($contents);
?>
L'exemple ci-dessus va afficher :
Index: http://www.example.com/svnroot/trunk/foo =================================================================== --- http://www.example.com/svnroot/trunk/foo (.../foo) (revision 23) +++ http://www.example.com/svnroot/branches/dev/foo (.../foo) (revision 27) // further diff output
Exemple 2671. Diffing two revisions of a repository path
This example implements a wrapper function that allows a user to easily diff two revisions of the same item using an external repository path (the default syntax is somewhat verbose):
<?php
function svn_diff_same_item($path, $rev1, $rev2) {
return svn_diff($path, $rev1, $path, $rev2);
}
?>
Exemple 2672. Portably diffing two local files
This example implements a wrapper function that portably diffs two local files, compensating for the realpath() fix and the backslashes bug:
<?php
function svn_diff_local($path1, $rev1, $path2, $rev2) {
$path1 = str_replace('\\', '/', realpath($path1));
$path2 = str_replace('\\', '/', realpath($path2));
return svn_diff($path1, $rev1, $path2, $rev2);
}
?>
