Bug #15665 Updated: readdir() crashes

ID: 15665 Updated by: jason@jase.org Reported By: david@acz.org Status: Open Bug Type: Reproducible crash Operating System: FreeBSD 4.4-STABLE PHP Version: 4.1.1 New Comment: See: http://bugs.php.net/bug.php?id=16905 (closed) && http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/37825 (patch) Jason Previous Comments: ------------------------------------------------------------------------ [2002-04-13 08:55:39] noemail@a.ml forgon to tell you... apache 1.3.22 and php4.1.1 (both from the ports collection) ------------------------------------------------------------------------ [2002-04-13 08:54:30] noemail@a.ml I have the same problems with a script under freebsd4.5-release. It just started crasching out of nothing. No change in the dirscancode, no change on the server. Worked just fine before yesterday. The only way to run the script now is to press the updatebutton in internetexplorer several times quite quickly, it works when I do so (I get about 5-6 httpds wotrking in the background). This is so strange. ------------------------------------------------------------------------ [2002-02-22 03:47:22] david@acz.org The option is --enable-debug, right? --with-debug appeared to do nothing. When compiled with --enable-debug, the script did not crash. But it certainly crashes with a normal build without debugging. ------------------------------------------------------------------------ [2002-02-21 19:30:43] david@acz.org I'll compile PHP from source with debugging and test tomorrow. Can't do it today since I just changed the code to exec find, and it already processed today's files (is a webserver log processing helper script). You're right, I know about the 0/false issue, but I was lazy since all the filenames will always be fully qualified hostnames :) I don't remember exactly how many times readdir() was being called before it crashed, but probably somewhere between 100-200. When it first crashed, I noticed I had been calling that function a lot without using closedir(), but after I added it and only called it once on a single directory, it still crashed. ------------------------------------------------------------------------ [2002-02-21 18:50:04] mfischer@php.net Can you enable --with-debug please and post a backtrace? Btw, how often have you to call readdir() until it crashes? Btw, your code won't work for directories containing files or dirs naming like '0'; see the manual page and use 'while (false !== ($s = readdir() ...' Also, can you try the source relese itself please and not a/the port? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
