It's strange. Works for me, and there is another guy with apache 2.0 who use it. Can you describe your test case? Maybe you've found another problem? Previous Comments: ------------------------------------------------------------------------ [2003-08-13 21:43:09] [EMAIL PROTECTED] I could finally reproduce this. The patches didn't make any difference. ------------------------------------------------------------------------ [2003-07-28 04:56:01] wmeler at wp-sa dot pl What is --worker=MPM ? Did you mean --mpm=worker ? If so, with php4-STABLE-200307280730 I got in error_log (configure options the same as before): [Mon Jul 28 11:41:58 2003] [notice] Apache/2.0.47 (Unix) PHP/4.3.3RC2-dev configured -- resuming normal operations [Mon Jul 28 11:42:28 2003] [notice] child pid 31209 exit signal Segmentation fault (11) [Mon Jul 28 11:42:30 2003] [notice] child pid 31233 exit signal Segmentation fault (11) [Mon Jul 28 11:42:31 2003] [notice] child pid 31252 exit signal Segmentation fault (11) [Mon Jul 28 11:42:33 2003] [notice] child pid 31271 exit signal Segmentation fault (11) Finally I saw the page I requested, but it was after 4 crashes - mozilla tries to reload page if server disconnects without response. ------------------------------------------------------------------------ [2003-07-21 04:18:51] wmeler at wp-sa dot pl patches work together http://strony.wp.pl/wp/wmeler/ ------------------------------------------------------------------------ [2003-07-21 02:46:15] wmeler at wp-sa dot pl As I said - heap corrupted. backtrace: #0 0x40393966 in _efree (ptr=0x42671030, __zend_filename=0x403e5840 "/tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c", __zend_lineno=291, __zend_orig_filename=0x403e5ca0 "/tmp/php4-STABLE-200307081130/Zend/zend_variables.c", __zend_orig_lineno=44) at /tmp/php4-STABLE-200307081130/Zend/zend_alloc.c:259 #1 0x403a3e18 in _zval_dtor (zvalue=0x81d6018, __zend_filename=0x403e5840 "/tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c", __zend_lineno=291) at /tmp/php4-STABLE-200307081130/Zend/zend_variables.c:61 #2 0x4039b878 in _zval_ptr_dtor (zval_ptr=0x81d60d4, __zend_filename=0x403e5ca0 "/tmp/php4-STABLE-200307081130/Zend/zend_variables.c", __zend_lineno=167) at /tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c:291 #3 0x403a40d2 in _zval_ptr_dtor_wrapper (zval_ptr=0x81d60d4) at /tmp/php4-STABLE-200307081130/Zend/zend_variables.c:167 #4 0x403aa7a3 in zend_hash_destroy (ht=0x81bfa94) at /tmp/php4-STABLE-200307081130/Zend/zend_hash.c:543 #5 0x4039b361 in shutdown_executor (tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/Zend/zend_execute_API.c:186 #6 0x403a546d in zend_deactivate (tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/Zend/zend.c:666 #7 0x40374772 in php_request_shutdown (dummy=0x0) at /tmp/php4-STABLE-200307081130/main/main.c:995 #8 0x403c4923 in php_apache_request_dtor (r=0x81a6830, tsrm_ls=0x81aa7f0) at /tmp/php4-STABLE-200307081130/sapi/apache2handler/sapi_apache2.c:445 #9 0x403c4c4d in php_handler (r=0x81a6830) at /tmp/php4-STABLE-200307081130/sapi/apache2handler/sapi_apache2.c:541 #10 0x808269e in ap_run_handler (r=0x81a6830) at config.c:194 With my patch there are almost no problems. The problem is that shutdown function won't execute - EG(timeout) flag should be cleared before execution of shutdown function. I can correct it if you want. ------------------------------------------------------------------------ [2003-07-21 02:07:48] wmeler at wp-sa dot pl I took few days off. You know - holidays. My config.nice : './configure' \ '--disable-all' \ '--with-apxs2=/usr/local/apache2/bin/apxs' \ '--with-config-file-path=/usr/local/apache2/conf/' \ '--enable-debug' \ "$@" my script: <? function shutdown() { echo strlen($GLOBALS['a']); } set_time_limit(1); register_shutdown_function('shutdown'); while (true) $a.='a'; I use apache 2.0.47 with config.nice: "./configure" \ "--enable-so" \ "--with-mpm=worker" \ "$@" Now I have SIGSEGVs instead of hangs :) - probably longjump hit in the middle of emalloc/erealloc and memory cache is corrupted. I used my own module before, witch uses shared variables and locks - thats why it hanged. Now - without my module it just crashes :). ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
