Bug #13182 Updated: session_start() can't create a _new_ session control file.

ID: 13182 Updated by: yohgaki Old Summary: session_start() can't create a _new_ session control file. Reported By: d99alu@efd.lth.se Status: Open Bug Type: Session related Operating System: Solaris 7 Old PHP Version: 4.0.6 PHP Version: 4.1.1 New Comment: Version update. Previous Comments: ------------------------------------------------------------------------ [2002-01-15 03:34:49] yohgaki@php.net Got feedback from a user. -- feedback from samcooley@yahoo.com -- Hello, I was hoping you could re-open PHP-BUG #13182. I have completed a test in 4.1.1 and receive the same error. I have also attempted to compile a snapshot from CVS but the build failed so I will have to tweak it and get back to you on that. As for this bug, I am attaching the error on top of a phpinfo() page. I originally tried it in 4.0.6 or some older release. The only configure params, as you can see, are the Roxen location and the Sybase location (for Sybase support). I have tested this application from 4.0.0 on in Apache on Win2000, Solaris 7 and Solaris 8. I have tested it with 4.0.6 on Roxen with Solaris 7. So the difference here (and I have really tried to bring the configs as close as possible) seems to be the Solaris 7 vs 8. I will try and gather more information but would appreciate the bug being reopened as I feel it is reproducible. Regards, Sam Cooley __________________________________________________ Do You Yahoo!?

Thank you -- Yasuo ------------------------------------------------------------------------ [2001-09-06 14:16:14] d99alu@efd.lth.se We installed php 4.0.6 in a Roxen 2.1.625 web server on Solaris 7. Now we have a problem with temporary session files. The session_start() command will abort with the following error message: Warning: open(/tmp/sess_e8771af1171a6cbdf51eebdba5199d25, O_RDWR) failed: m (0) in [path/file.php] on line 78 Warning: open(/tmp/sess_e8771af1171a6cbdf51eebdba5199d25, O_RDWR) failed: m (0) in Unknown on line 0 Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0 The thing is that session.save_path is correct. It points to /tmp, where the web server and php has write permissions. The session controller can read and write existing files. The problem occurs only when session_start() has to create a _new_ session control file. If we use fopen(), we can read and write files in /tmp. If we create a file with the name of the supposed session control file (sess_..., the name stated in the error message from session_start()) with fopen() and then reload the page, session_start() will execute correctly, using the file we just created for it. Then php will access the file correctly, writing and reading session variables just as it is supposed to. So, again, the problem occurs only when session_start() has to create a _new_ session control file. Shouldn't a file be created automatically if it doesn't exist? The only strange thing with the installation of PHP on Roxen was that no binary file was created. We can't find the stand-alone program to execute php files from the shell. This happened even though no error message was given at the time of installation. The roxen installation was made as the config script suggested. Do you have a clue why this problem occurs? What our research toold us is: "If the 'open' is a system call, then this is the expected behavior. You need to provide a O_CREAT (or O_APPEND, don't know which) that will automatically create the file if it doesn't exist. Just providing O_RDWR/RDONLY will not create the file, and will return an error if the file doesn't exist. This is the correct behavior for a POSIX open system call."
