#49039 [Fbk]: Can't pass file name with subfolder name 3 characters or less

ID: 49039 Updated by: pajoye@php.net Reported By: sant9442 at gmail dot com Status: Feedback Bug Type: CGI related Operating System: win32 only - Windows PHP Version: 5.3.0 Assigned To: pajoye New Comment: Which windows version do you use? Previous Comments: ------------------------------------------------------------------------ [2009-08-10 15:17:13] pajoye@php.net Hi, I was not able to reproduce this problem using: F:\wc63>dir <JUNCTION> http [F:\wc63\http-1234] <DIR> http-1234 and the following call: ..\obj\Debug_TS\php-cgi.exe f:\wc63\http\pwe\t.php X-Powered-By: PHP/5.3.1-dev Content-type: text/html included F:\wc63\http-1234\pwe script being: <?php echo "included\n"; print_r(getcwd()); Are you sure about the last line of the processmonitor log? G:\files\php\php5-3-1-snapshot\pwephpinfo.php NAME NOT FOUND As it is not only missing a back slash but the path itself is completely wrong. It should have been: D:\wc63\http\pwe\phpinfo.php If you still get the same (wrong) results, please give me a way to reproduce it. Using one directory tree (D:\wc63\http with D:\wc63\http-1234 for example) and how exactly you call php. ------------------------------------------------------------------------ [2009-07-23 23:15:20] sant9442 at gmail dot com Sure thing! Btw, take a look at the last line for the 5.3 Process Monitor dump, where it shows: G:\files\php\php5-3-1-snapshot\pwephpinfo.php NAME NOT FOUND Notice that it is missing a slash, so it seems its pointer movement is off by one somewhere in the code, and I think this might be part of the GPF that might occur as mentioned in bug #49040. Thanks ------------------------------------------------------------------------ [2009-07-23 23:02:57] pajoye@php.net Thanks for the clear explanation :) Ok, so it may be related to a bug with junctions and symlink in 5.3. I will check it while working in the other related bugs (august, not before :). ------------------------------------------------------------------------ [2009-07-23 23:02:25] sant9442 at gmail dot com Small followup. I used SysInterna's ProcessMonitor and what I found, that PHP 5.3 has a REVERSE ORDER LOOKUP of symbol link vs PHP 5.2.6 For example, for PHP 5.2.6, Process Monitor shows: IRP_MJ_CREATE D:\ SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63 SUCCESS IRP_MJ_CLEANUP D:\ SUCCESS IRP_MJ_CLOSE D:\ SUCCESS IRP_MJ_CREATE D:\wc63 SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http SUCCESS IRP_MJ_CLEANUP D:\wc63 SUCCESS IRP_MJ_CLOSE D:\wc63 SUCCESS IRP_MJ_CREATE D:\wc63\http REPARSE IRP_MJ_CREATE D:\wc63\http-4529 SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http-4529\pwe SUCCESS IRP_MJ_CLEANUP D:\wc63\http-4529 SUCCESS IRP_MJ_CLOSE D:\wc63\http-4529 SUCCESS IRP_MJ_CREATE D:\wc63\http-4529\pwe REPARSE IRP_MJ_CREATE D:\wc63\http-4529\pwe SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http-4529\pwe\phpinfo.php SUCCESS In PHP 5.3, it does it reverse manner: IRP_MJ_CREATE D:\wc63\http-4529\pwe REPARSE IRP_MJ_CREATE D:\wc63\http-4529\pwe SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http-4529\pwe\phpinfo.php SUCCESS IRP_MJ_CLEANUP D:\wc63\http-4529\pwe SUCCESS IRP_MJ_CLOSE D:\wc63\http-4529\pwe SUCCESS IRP_MJ_CREATE D:\wc63\http REPARSE IRP_MJ_CREATE D:\wc63\http-4529 SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http-4529\pwe SUCCESS IRP_MJ_CLEANUP D:\wc63\http-4529 SUCCESS IRP_MJ_CLOSE D:\wc63\http-4529 SUCCESS IRP_MJ_CREATE D:\wc63 SUCCESS IRP_MJ_DIRECTORY_CONTROL D:\wc63\http SUCCESS IRP_MJ_CLEANUP D:\wc63 SUCCESS IRP_MJ_CLOSE D:\wc63 SUCCESS IRP_MJ_CREATE D:\wc63\http SUCCESS IRP_MJ_FILE_SYSTEM_CONTROL D:\wc63\http SUCCESS IRP_MJ_CLEANUP D:\wc63\http SUCCESS IRP_MJ_CLOSE D:\wc63\http SUCCESS IRP_MJ_CREATE G:\files\php\php5-3-1-snapshot\pwephpinfo.php NAME NOT FOUND So PHP 5.3 symbolic link logic resolution logic seems broken :-) -- ------------------------------------------------------------------------ [2009-07-23 22:49:24] sant9442 at gmail dot com > I find this whole report confusing. Let us try to make it simple. Yes I agree, and thanks to your clue about junctions points and my yesterday attempt to fool it with a junction pointing to a longer folder name, I think I found the problem. In our hosting server product installation folder, for example: d:\wc63 we have a locked in sub folder name "HTTP" d:\wc63\http would be the so called "document root" folder. Now, for my development or support, I create multiple HTTP-build# to represent versions of our templates: http-4521\ http-4522\ http-4525\ http-4529\ or I might have customer's copies of their HTTP folder http-customer1\ http-customer2\ What I do is create a junction to symbolic name HTTP for example: junction HTTP HTTP-4529 So in DOS, the DIR listing shows: 06/20/2009 09:22 PM <JUNCTION> http 07/23/2009 05:48 PM <DIR> http-4529 Now, I have a PWE (PHP for wildcat) script in http-4529\pwe\phpinfo.php which is linked to: http\pwe\phpinfo.php PHP 5.3 has a problem with this: php.exe d:\wc63\http\pwe\phpinfo.php Could not open input file: d:\wc63\http\pwe\phpinfo.php php.exe d:\wc63\http-4529\pwe\phpinfo.php HELLO PRIVATE It appears PHP 5.3 has an issue with symbolic links, This is not the case with 5.2.6. g:\php526\php.exe d:\wc63\http\pwe\phpinfo.php HELLO PRIVATE Thanks ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
