ID: 13806 User updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Old Summary: zlib compression is broken? Status: Open Old Bug Type: Zlib Related Bug Type: Reproducible crash Old Operating System: Linux 2.4.4/glibc 2.2.2 Operating System: Linux 2.4.14-pre3/glibc 2.2.2 Old PHP Version: 4.0CVS-2001-10-24 PHP Version: 4.1.0 RC CVS-2001-10-24 New Comment:
via-rihine chipset NIC dvriver seems to be fixed in 2.4.13, finanlly :) I could upgrade kernel from 2.4.4 to 2.4.14-pre3. It seems many *.c files are not modified for new asm/*.h files, yet. (It was the same, when I tried 2.4.13) Therefore, I couldn't use the same config as 2.4.4. I was using 2.4.4 kernel that comes with my distribution. Most of kernel drivers/options are compiled in or compiled as module. I'm using kernel optimized for my test PC now. Kernel may crash with other options/modules... Anyway, PHP behaves much better with newer kernel. New behavior is as follows. * PHP outputs the top part of the test script "<?php phpinfo(); ?>" correctly. * PHP sends a lot of garbages with the test script. * Kernel seems to stop freezing. + PHP stopped complaining about many memory leaks at shutdown. Problem: * When memory limit is enabled, PHP do not terminate script execution even if it is already exhausted memory. (I get multiple error message for a single execution as attached apache error log) * PHP can't send proper phpinfo() output. * PHP segfaults with my scripts. I changed bug type form Zlib Related to Reproducible crash. If your PHP does not segfault easily, please let me know. I'll send back trace. == apache error log start == /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) /home/yohgaki/public_html/test/phpinfo.php(1) : Fatal error - Allowed memory size of 8388608 bytes exhausted at zlib.c:995 (tried to allocate 2915587 bytes) == end == Previous Comments: ------------------------------------------------------------------------ [2001-10-27 16:24:56] [EMAIL PROTECTED] Just an update. Better procedure to reproduce this bug. I can reproduce this bug on RedHat 7.1(kernel 2.4.7) and Kondara 2.0(Kernel 2.4.4) I think this bug is *critical* and better to be fixed/workarounded before 4.1.0 release.... (Or disable zlib.output_compression?) Caution: This can crash your linux kernel and may crash filesystem. 1) Get 4.1.0RC CVS source 2) Copy php.ini-recommend to php.ini and enable zlib.output_compression zlib.output_compression=On 3) configure/build/install PHP 4.1.0RC './configure' \ '--with-apxs' \ '--disable-short-tags' \ '--without-mysql' \ '--without-pear' \ '--with-zlib' \ '--enable-debug' 4) Create test php script containing <?php phpinfo(); ?> 5) restart httpd, diplay the test script 6) Stop httpd and check apache error log see if memory leak is reported or not. ------------------------------------------------------------------------ [2001-10-27 16:09:07] [EMAIL PROTECTED] This bug may be related to following bugs. http://bugs.php.net/bug.php?id=12270 http://bugs.php.net/bug.php?id=13698 ------------------------------------------------------------------------ [2001-10-24 08:46:19] [EMAIL PROTECTED] This is not exactly what I've reported, but if following problem is fixed, this bug may be fixed. Fixing this may fix bug #13698, also. (CGI version segfaults at shutdown) php.ini: php.ini-recommened. Only change I've made is enable ZLIB compression. If zlib compression is off, it seems working.
