It is still reproducible with php5.2-200709071230 (snapshot). php-5.2.3 worked fine. Reverting this commit [1] solves the problem. I'm using the tarballs from php.net, no patches. This change breaks certain Typo3 setups. [1] http://cvs.php.net/viewcvs.cgi/php-src/sapi/cgi/cgi_main.c?r1=1.267.2.15.2.42&r2=1.267.2.15.2.43&pathrev=PHP_5_2 (Fixed bug #40419 (Trailing Slash in CGI request don't work)) Reproduce code: --------------- (a web server, lighttpd in this case, is set up at 127.0.0.1:8000; foo.php5.2.3 is handled by php5.2.3, foo.php5.2.5dev by php5.2-200709071230; both binaries have the -n option passed; docroot is /var/tmp/php) christian@tux /var/tmp/php $ mkdir foo christian@tux /var/tmp/php $ echo '<?php print getcwd(); ?>' > foo/bar.php christian@tux /var/tmp/php $ ln -s foo/bar.php bar.php5.2.3 christian@tux /var/tmp/php $ ln -s foo/bar.php bar.php5.2.5dev christian@tux /var/tmp/php $ curl http://localhost:8000/bar.php5.2.5dev /var/tmp/php/foo christian@tux /var/tmp/php $ curl http://localhost:8000/bar.php5.2.3 /var/tmp/php Expected result: ---------------- >=php-5.2.4 should behave exactly as <php-5.2.4; above commands should show "/var/tmp/php" (= the directory of the symlink; not the directory of the target of the symlink). Actual result: -------------- getcwd() returns /var/tmp/php/foo -- the directory which contains the target of the requested symlink. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42587&edit=1
