Operating system: linux 2.4 glibc 2.1
PHP version: 4.0.6
PHP Bug Type: Unknown/Other Function
Bug description: pthread_create in extension function never returns
I've created a wrapper extension for PHP to include my c++ library in as a
shared module. My c++ library create a thread with pthread_create somewhere
in the code. Using my library inside a stand-alone application works great,
but when using it in PHP extension. The function never returns.
I compiled PHP with these options
--with-apxs --without-mysql
I hadto disable GetRUsage to be able to compile PHP.
So PHP is an Apache Module.
I have Pentium 200Mhz with 92MB Linux 2.4.9 with glibc 2.1.
In fact, only in the main thread (I suppose to be the main thread) the
pthread_create function does not returns. The child thread is create, and
this child can create sub thread and their call to pthread_create
returns.
The problem can be easily reproduce by adding a pthread_create(&thread_id,
NULL, threadloop, NULL); directly in an extension function. I mean by
extension function the function beginning with PHP_FUNCTION.
Example:
void* threadloop (void*arg)
{
//This line is execute after pthread_create
}
PHP_FUNCTION(test)
{
pthread_t othread;
pthread_create (&othread, NULL, threadloop, NULL);
//The execution never comes here
}
--test.php
<HTML>
<BODY>
<?php test();
//Script hang on previous line
?>
</BODY>
</HTML>
I would like to know if it's a bug in linux pthread implementation or in
PHP.
