#18869 [Opn]: include and include_once fail under load in iPlanet/NSAPI

ID: 18869 User updated by: fillmore@NRCan.gc.ca Reported By: fillmore@NRCan.gc.ca Status: Open Bug Type: Scripting Engine problem Operating System: Solaris 8 PHP Version: 4.2.2 New Comment: A colleague pointed out this bug entry to me: http://bugs.php.net/bug.php?id=16037 We recoded our scripts to use the string variable substitution syntax suggested by that bug report, and reran our load tests without disabling multithreading, and it now works! I think that this proves that there is something wrong in the PHP script engine. - Bob Previous Comments: ------------------------------------------------------------------------ [2002-08-12 12:32:20] rasmus@php.net PHP should be threadsafe, but chances are some of the 3rd party libs you have linked in are not. It is the same problem the threaded version of Apache2 has. A lot of UNIX libraries are simply not threadsafe and we don't have a good handle on which ones are and which ones aren't. Having said that, the NSAPI code has not had extensive testing, so there could very well be a bug lurking. Try Apache instead. ------------------------------------------------------------------------ [2002-08-12 12:27:50] fillmore@NRCan.gc.ca A site was developed with scripts that use "include" and "include_once", and it worked fine until the client load increased. The symptoms include various parser errors that seem to indicate that code from an include file was truncated or corrupted. The errors are reproduceable using a web load generator. Assuming that the problem may be caused by code that is not thread-safe, I configured iPlanet web server to limit the number of threads for PHP to 1 - this fixed the problem. However, PHP should really be thread-safe when running in an iPlanet 4.1/NSAPI environment. Here are the obj.conf changes to fix the problem: Init fn="thread-pool-init" name="php-thread-pool" MinThreads="1" MaxThreads="1" QueueSize="300" Init fn="load-modules"funcs="php4_init,php4_close,php4_execute,php4_auth_trans" shlib="/suitespot/bin/libphp4.so" pool="php-thread-pool" Here is the config call: CC=gcc ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/ph p/etc --with-nsapi=/suitespot --enable-libgcc --enable-dbase --with-xml Thanks, Bob Fillmore ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18869&edit=1
