#43173 [Opn->Fbk]: FastCGI broken due to invalid descriptor

ID: 43173 Updated by: jani@php.net Reported By: davidb at chelsea dot net -Status: Open +Status: Feedback Bug Type: CGI related Operating System: Solaris 2.8 PHP Version: 5.2.4 Assigned To: dmitry New Comment: And my point was that this happened (yes, it was needed to fix certain issues): File: NEWS -----8<------ 31 May 2007, PHP 5.2.3 - Changed CGI install target to php-cgi and 'make install' to install CLI when CGI is selected. (Jani) -----8<------ So what you have there called 'php' is actually the CLI binary. The cgi binary is called 'php-cgi'.. Previous Comments: ------------------------------------------------------------------------ [2007-11-19 19:35:59] davidb at chelsea dot net Greetings. I don't know how else to convince everyone that I'm using the right file. But, here goes: - I run the EXACT SAME CONFIGURE SCRIPT for 5.2.0 and 5.2.4. It looks like this: ./configure --prefix=/opt/php/5.2.4 \ --with-zlib=/usr/local \ --with-mysql=/usr/local \ --with-db4=/usr/local \ --with-config-file-path=/usr/local/etc/php \ --enable-gd-native-ttf \ --with-jpeg-dir=/usr/local \ --with-openssl=/usr/local \ --with-gd=/usr/local \ --with-png-dir=/usr/local \ --with-freetype-dir=/usr/local \ --with-mhash=/usr/local \ --with-mm=/usr/local \ --with-xsl=/usr/local \ --with-zend-vm=CALL \ --with-curl=/usr/local \ --with-imap=/usr/local \ --with-imap-ssl=/usr/local \ --with-libxml-dir=/usr/local \ --enable-spl \ --enable-calendar \ --enable-fastcgi \ --enable-force-cgi-redirect \ --enable-sockets \ --enable-mbstring You'll know the first line allows us to change the directory that we build in so we can test new versions. - /usr/local/bin/php5 is a symlink pointing to the currently active version on the test machine. We also sometimes exec /opt/php/5.2.4/bin/php directly, there's no difference in failure type. - 5.2.0 works without a problem (as to 5.0.3 and 4.X); 5.2.3 and 5.2.4 do not. - Here's the output of ls -l: -rwxr-xr-x 1 root other 39685444 Aug 12 08:34 /opt/php/5.2.0/bin/php* -rwxr-xr-x 1 root other 40515124 Aug 6 10:49 /opt/php/5.2.3/bin/php* -rwxr-xr-x 1 root other 41271848 Nov 13 10:37 /opt/php/5.2.4/bin/php* We've been doing this with PHP/FastCGI for years now. Please advise. If there's anything else you'd like to see, please let me know and I'll be happy to add it in. How/where does PHP decide to launch in FastCGI mode v. CGI mode when it is exec'd by the web server? Did the win32 changes in 5.2.2 leak into UNIX somehow? ------------------------------------------------------------------------ [2007-11-19 18:59:34] jani@php.net And you're sure php5 is the cgi binary and not the CLI binary? As of some version we changed the binary name to be php-cgi. What was the configure line you used? ------------------------------------------------------------------------ [2007-11-16 13:53:20] davidb at chelsea dot net PHP under apache uses it's own process manager to spawn children. I believe you can disable that so Apache does it itself, but I prefer to manage it in PHP so we can control the number of PHP works without editing httpd.conf. Here's the relevant configuration. In httpd.conf, I set up the PHP server as follows: AddHandler php-fastcgi .php <Location /cgi-bin/php> SetHandler fastcgi-script </Location> Action php-fastcgi /cgi-bin/php DirectoryIndex index.html index.shtml index.php AddType application/x-httpd-php .php FastCgiServer /export/httpd/DOMAINS/fastcgi.com/cgi-bin/php -processes 1 The FastCgiServer is a shell script that execs the PHP process. We use it to set shell variables that we might need: #!/bin/sh PHP_FCGI_CHILDREN=2 export PHP_FCGI_CHILDREN exec /usr/local/bin/php5 All of this has worked fine for PHP 4.X, 5.0.X, 5.1.X, and 5.2.0. It broke sometime after 5.2.0. David. ------------------------------------------------------------------------ [2007-11-16 13:23:48] dmitry@php.net What do you mean in "Using the php proc manager to control children"? Could you show your configuration files. ------------------------------------------------------------------------ [2007-11-15 23:28:25] davidb at chelsea dot net I am absolutely, 100% certain that I'm using the right binary. I've gone back and forth multiple times, and it is reproducible. Since this is for http://www.fastcgi.com, I have added incentive to get it figured out. How can I help troubleshoot this? How does php decide if it's running as a CGI or a FastCGI? How did that part of the code change? I'm not a C coder unfortunately (limited read-only knowledge) but from the truss() I'm guessing that the check is failing and it's using the cgi interfaces instead of the fastcgi interface when it wakes up. The web server is running as follows: - apache 1.3.39 - mod_fastcgi (previous versions, and also tried latest release of a few days ago to see if it makes a difference) - Using the php proc manager to control children, NOT the apache procmanager (this is the default mode of operation, or at least it was) - The only environment variable is PHP_FCGI_CHILDREN=2 - suexec is spawning this As I mentioned before, I have an identical configuration for 5.2.0 and it works fine. Thanks. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
