#40326 [Opn->Fbk]: Can't open file from cwd if parent folder not readable

ID: 40326 Updated by: tony2001@php.net Reported By: sborrill at precedence dot co dot uk -Status: Open +Status: Feedback Bug Type: Streams related Operating System: NetBSD 3.1_STABLE PHP Version: 5.2.0 New Comment: Please provide an account on this machine. Previous Comments: ------------------------------------------------------------------------ [2007-02-10 21:39:07] sborrill at precedence dot co dot uk I've tracked this down to changes to virtual_file_ex() which is called from expand_filepath(). expand_filepath() returns "/file" from "file" with 5.2.0 (and later), but returns "file" with 5.1.6 and earlier. This is down to changes between revisions 1.74.2.9 (v5.1.6) and 1.74.2.9.2.9 (v5.2.0) of TSRM/tsrm_virtual_cwd.c. I've not yet tracked it down further. ------------------------------------------------------------------------ [2007-02-10 19:25:28] sborrill at precedence dot co dot uk Yes, as per my original bug report, it is not fixed in the daily snapshots. I've confirmed it today's too. I can recreate it with the cli php binary too (i.e. I don't have to test it from Apache). ------------------------------------------------------------------------ [2007-02-05 13:51:27] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip ------------------------------------------------------------------------ [2007-02-05 13:45:38] sborrill at precedence dot co dot uk OK, permissions are nearly the same (except in our case, it's the parent of the www directory that is -r not the www itself, but that's probably unimportant). The getcwd() line shows a difference though. On NetBSD and other Unix OSes (all except for Linux?) getcwd() returns FALSE as noted in http://bugs.php.net/bug.php?id=24185 Perhaps the reason it's working for you on Linux is because your getcwd() _isn't_ returning FALSE and there's now an extra getcwd() call in the fopen codepath. N.B. as in my original report, with PHP 5.1.6, getcwd() returned FALSE, but fopen worked nonetheless. Also, the patches to PHP in the NetBSD package are the same between 5.1.6 and 5.2.0 (or if they differ it's in an unrelated section). The patches related to php.ini, configure, curl and imap/c-client only. Everything else is stock: http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/lang/php5/patches/ ------------------------------------------------------------------------ [2007-02-05 09:40:56] tony2001@php.net >What OS?
