PLEASE give proper steps to reproduce this. Preferrably something we can simply cut'n'paste.. Previous Comments: ------------------------------------------------------------------------ [2009-07-29 16:34:25] rusxakep at gmail dot com You can use any other directory where you are able to do it. You can use the virtual machine (like VirtalBox or VMware) and so forth. Installation "execution bit" on/usr/bin/strace is necessary for situation creation where the error in function file_exist() appears. It is necessary for more exact understanding of an error. In a real situation which is described in my first post, the role strace is fulfilled by the program written on C with "execution bit enable". If still something is not clear, write, I will explain.) ------------------------------------------------------------------------ [2009-07-28 20:49:00] j...@php.net My /home dir isn't writable by anyone. So how could it work? And what does setting those permissions on strace help to debug this? ------------------------------------------------------------------------ [2009-07-28 20:12:08] rusxakep at gmail dot com Jani, Is bug reproducing ONLY with using "set execution bit"! Simple way test with strace output: 1. Temprorarly set "chmod 6755" to /usr/bin/strace binary for correct test. 2. Create simple CONSOLE test.php file and place to /home/1/ directory (owner should be root.root): #!/usr/bin/php -q <?php if (!file_exists("/home/1/2/3")) mkdir("/home/1/2/3",0700,true); ?> 3. Run this script under any unprivileged user with next cmd: "su - someuser -c "/usr/bin/strace /home/1/test.php" First run test.php create directory /home/1/2 and /home/1/2/3 successfully with "someuser" owner and 0700. Second run test.php script must be finish w/o any messages, because directory already exists, but function file_exists() incorrectly fulfils and produces that the directory does not exist, though it is. Try it! If something else is not clear, I will explain more in detail.) ------------------------------------------------------------------------ [2009-07-28 19:52:47] j...@php.net Your report is quite confusing. You talk about creating /home/user/2/3 directories (note the missing 1?) but your straces show quite different outputs. Please, come up with _simple_ way to reproduce this. Simple meaning ONE php (and PHP ONLY!) file. ------------------------------------------------------------------------ [2009-07-27 09:19:12] rusxakep at gmail dot com Added -D__USE_FILE_OFFSET64 to CFLAGS and re-compile all php stuff.
