Bug #65697 [Nab]: is_link not working with windows junctions

Edit report at https://bugs.php.net/bug.php?id=65697&edit=1 ID: 65697 User updated by: giunta dot gaetano at gmail dot com Reported by: giunta dot gaetano at gmail dot com Summary: is_link not working with windows junctions Status: Not a bug Type: Bug Package: *Directory/Filesystem functions Operating System: win7 64bit PHP Version: 5.4.19 Block user comment: N Private report: N New Comment: Mmm, if it walks like a duck and quacks like a duck... For all scenarios I can figure (backups, deploying code using symlinks), treating a junction as a symlink makes more sense than not doing it. Right now the only way to tell if a folder is actually a "real one" or not is to use the array_diff trick I put in the test script. It looks hackish, cumbersome, and why should lstat() treat a junction differently than is_link() anyway?) It is true that windows versions starting with Vista do create symlinks by default, but tools like "Link Shell Extension" or the venerable sysinternals junction.exe still allow one to create Junctions. Previous Comments: ------------------------------------------------------------------------ [2013-09-18 19:00:39] pajoye@php.net Junctions are not symlinks, the result is correct. Also the junctions pointing to a directory may work. I remember some windows version specific changes here, where it ended as symlink or junction (recent always do it as symlonk afair) ------------------------------------------------------------------------ [2013-09-18 12:51:32] giunta dot gaetano at gmail dot com Description: ------------ is_link seems to return false for junction points which show up as <JUNCTION> when using the DIR command. It seems to work for junctions which show up as <SYMLINKD> when using the DIR command. tested on php 5.3.27 and 5.4.14 (32 bit of course) Test script: --------------- <?php $paths = array( "linksource", "linktarget", "linktarget2" ); foreach ( $paths as $path ) { echo "----\n $path\n"; var_dump( is_link( $path ) ); var_dump( is_dir( $path ) ); var_dump( array_diff( stat($path), lstat($path) ) ); } Expected result: ---------------- results of DIR command: 07/09/2013 15:59 <DIR> linksource 07/09/2013 19:11 <JUNCTION> linktarget [D:\htdocs\linksource] 18/09/2013 14:30 <SYMLINKD> linktarget2 [linksource] Actual result: -------------- D:\htdocs>php linktest.php ---- linksource bool(false) bool(true) array(0) { } ---- linktarget bool(false) bool(true) array(8) { [2]=> int(16895) [8]=> int(1378562389) [9]=> int(1378562389) [10]=> int(1378562389) ["mode"]=> int(16895) ["atime"]=> int(1378562389) ["mtime"]=> int(1378562389) ["ctime"]=> int(1378562389) } ---- linktarget2 bool(true) bool(true) array(8) { [2]=> int(16895) [8]=> int(1378562389) [9]=> int(1378562389) [10]=> int(1378562389) ["mode"]=> int(16895) ["atime"]=> int(1378562389) ["mtime"]=> int(1378562389) ["ctime"]=> int(1378562389) } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65697&edit=1
