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

ID: 49039 Comment by: sant9442 at gmail dot com Reported By: sant9442 at gmail dot com Status: Feedback Bug Type: CGI related Operating System: Windows PHP Version: 5.3.0 New Comment: From: pajoye@php.net > It does not make sense to me. > Are these paths real paths or mounted (virtual or not), > junctions, etc Good question. All of the above was tried. All this started with a programmer reported that our PHP extension PHP_WILDCAT.DLL called PWE (PHP Wildcat Extenson) for 5.2.6 was not working with 5.3.0. Our installed creates to sub folders for PWE sample scripts: Server side (using d:\wc63 install folder of our hosting server) d:\wc63\http\pwe d:\wc63\http\public\pwe In our system, http is inherently private (authentication is required) with the excepton of the public\ folder. So d:\wc6\http is the docuument root, and URL references will be: /pwe /public/pwe In any case, after downloading 5.3-WIN32 and the source code for VC6 builds, I recompiled the PHP_WILDCAT.DLL extension for 5.3. and the first test was: /pwe/phpinfo.php to see the Wildcat! extension module info. But I got the "No Input File Specified." error. I copied it to the public\pwe folder and tried it: /public/pwe/phpinfo.php and that worked. That began a 10 hour adventure to see what was going on. I focused on the the ini CGI settings which were: ;doc_root = cgi.force_redirect=0 ;cgi.fix_pathinfo=1 and I wasted time trying all kinds of variations to no avail. What I did finally realized that it wasn't related to our extension and could repeat the problem via the command line, by simply emulating what the web server would do: cd \wc63\http d:\wc63\php\php-cgi.exe d:\wc63\http\pwe\phpinfo.php d:\wc63\php would be where PHP installed, but it can be anywhere of course. The result of above is: Status: 404 Not Found X-Powered-By: PHP/5.3.0 Content-type: text/html No input file specified. Now, I have PHP 5.2.6, also installed d:\wc63\php526\php-cgi.exe d:\wc63\http\pwe\phpinfo.php X-Powered-By: PHP/5.2.6 Content-type: text/html HELLO PRIVATE Now, all I have to do is use a folder that is not 3 characters, which I have one called WCPHP which I created and copied the script to: d:\wc63\php\php-cgi.exe d:\wc63\http\wcphp\phpinfo.php Status: 404 Not Found Content-type: text/html HELLO PRIVATE Anyway, once I saw it was the 3 character PWE folder I was thinking of how to fool it or change our installer to use longer folder names. I even tried a junction cd \wc63\http junction wcphp pwe and it that didn't work which left me wondering if PHP-CGI.EXE was resolving the junction path. This is all odd and rest assured, whether anyone can repeat it or not, the issue does exist. I hope some one can trace thru the logic.

As shown in the last example, none of these php-cgi.exe command line issues appear in 5.2.6 or lesser version. Only with 5.3. Here is my analysis of the situation. In 5.3, there was a massive change to the parsing and file name resolution logic. There are issues with it. Unfortunately, I lack the time to get into a windows recompiling project I can trace it down. The last time I did that I lost a tooth. :-) Please also see bug #49040 which was found during the time trying to figure this out expecting it was related to the cgi ini settings and/or the env settings where were not the case. thanks ------------------------------------------------------------------------ [2009-07-23 19:25:10] pajoye@php.net Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ If any, try a 5.3 snapshot... ------------------------------------------------------------------------ [2009-07-23 19:22:43] jani@php.net Please try using this snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ ------------------------------------------------------------------------ [2009-07-23 19:09:07] sant9442 at gmail dot com It should be noted that we spend 10 hours on this issue, first believing it was related to changed to the php.ini options ;doc_root = ;cgi.fix_pathinfo = 1 cgi.force_redirect = 0 and CGI environment strings: DOCUMENT_ROOT=d:\wc63\http PATH_INFO=/pwe/helloworld.php SCRIPT_NAME=/pwe/helloword.php PATH_TRANSLATED=d:\wc63\http\pwe\helloworld.php SCRIPT_FILENAME=d:\wc63\http\pwe\helloworld.php which all research (googling) of "no input file specified" related to. Reqardless of what we tried, it would not work until I discovered the 3 character folder name off the root folder was the problem. Renaming it to 4 characters or more, solved the issue and that was discovered when all other URLS were working and we noticed the only difference was the 3 character length of the folder name. This comment is mentioned so that time isn't wasted on the above issues related and possible reasons for "no input file specified." ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
