-Summary: Segmentation fault with apache2 php pages not served
Reported By: [EMAIL PROTECTED]
-Status: Feedback
+Status: Open
-Bug Type: Apache2 related
+Bug Type: SWF related
Operating System: Red Hat Linux 7.1
PHP Version: 4.1.1
New Comment:
This has been hiding as feedback under Apache2, but it's
most likely not Apache2 related, and I didn't want this
patch, if valid, to be forgotten. So I'm reopening and
reclassifying as SWF related.
Thanks...

Please try again with Apache 2.0.35 (GA) and PHP from
CVS (either the 4.2.0 branch or HEAD).

I don't know much about cvs and how diff works. So I couldn't make
anything out of these lines. One thing I did was, removed --with-swf
from configure option and everything worked fine. I want to help but I
have a very slow pentium-1 computer and a slow dial up connection (in
punjab-IN) so it takes at least one hour to compile php alone. I know
little C so if you tell me what to add, what to remove and where then I
can make that change and try to compile again and see if that works.

Hmm .. have you compiled php with thread support?
It seems the swf module is missing an ZEND_INIT_MODULE_GLOBALS() call
in PHP_MINIT_FUNCTION().
Can you test this patch (against current CVS) ?

This time I compiled php with --enable-debug option to generate
backtrace.A
new file cgisock (0 size) is automatically created after this compile.
I think
problem is related to swf functions(swf.c). gdb results are at the
end:

After making and installing both apache and php when I started apache
and
tried to access http://localhost. It worked and apache test page was
displayed.
Then I tried to access a php file with only phpinfo() function.
Netscape displayed a message the document contained no date. Follwing
was added to apache error_log:

I stoped apache removed all logs files and tried /wwwroot/bin/httpd -X
after running 'ulimit -c unlimited' and
then accessed a php file with phpinfo() and lynx displayed unable to
access start document...unkonwn network error and exited.
/wwwroot/bin/httpd -X produced:
Segmentation fault
and exited.
No core file is produced under /wwwroot/bin (/wwwroot is apache 2.0
install directory). /wwwroot/bin has write permission for everyone.
Then I
tried the second option like this and was successful:

[2002-02-27 15:20:29] [EMAIL PROTECTED]
I did read the README file in sapi/apache2filter directory. But I think
it wasn't mentioned there that we should use Apache 2_0_31.
Anyway, I started from scratch again and tried each step one by one. I
forgot to generate back trace but I will generate it next time. But
this time I tried various configurations which are given below. In some
cases php 4.1.1 and apache 2_0_28 did work.
FIRST CONFIGURATION
----------
---------------------Apache 2.0--------------
./configure --prefix=/wwwroot --enable-so
---------------------PHP 4.1.1-----------------
./configure --prefix=/wwwroot/php --with-mysql
--with-java=/usr/java/j2sdk1.4.0
php did work and phpinfo() displayed information java library was
loaded.
But when jver.php was accessed lynx exited with following error:
Looking up localhost
Making HTTP connection to localhost
Sending HTTP request.
HTTP request sent; waiting for response.
Alert!: Unexpected network read error; connection aborted.
Can't Access `http://localhost/jver.php'
Alert!: Unable to access document.
nothing was added to logs/error_log or to php error log file (php error
logging was enabled and a file name was specified)
no segmentation fault etc was entered in error log.
Then I did this:
export
LD_LIBRARY_PATH=/usr/java/j2sdk1.4.0/jre/lib/i386/native_threads:/usr/java/j2sdk1.4.0/jre/lib/i386/client:/usr/java/j2sdk1.4.0/jre/lib/i386;
Every thing worked and when jver.php (sample file provided with java
ext) was
accessed java version etc. was displayed.
extension directory created was:
/wwwroot/php/lib/php/extensions/no-debug-zts-20010901/
Second Time
-----------
---------------Apache 2.0 Configure Options-------------------
./configure --prefix=/wwwroot --enable-auth-anon --enable-auth-db
--enable-auth-dbm --enable-auth-digest --enable-file-cache
--enable-echo
--enable-cache --enable-mem-cache --enable-example --enable-ext-filter
--enable-case-filter --enable-case-filter-in --enable-mime-magic
--enable-cern-meta --enable-expires --enable-usertrack
--enable-unique-id
--enable-ssl --enable-optional-hook-export
--enable-optional-hook-import
--enable-optional-fn-import --enable-optional-fn-export --enable-http
--enable-dav --enable-cgi --enable-info --enable-cgid --enable-dav-fs
--enable-vhost-alias --enable-speling --enable-actions --enable-rewrite
--enable-so
------------------------------PHP 4.1.1 ------------------------------
./configure --prefix=/wwwroot/php --with-mysql
--with-java=/usr/java/j2sdk1.4.0 --with-apxs2=/wwwroot/bin/apxs
--with-config-file-path=/wwwroot/php
phpinfo() worked and java library was loaded.
Java (jver.php) worked after exporting this:
export
LD_LIBRARY_PATH=/usr/java/j2sdk1.4.0/jre/lib/i386/native_threads:/usr/java/j2sdk1.4.0/jre/lib/i386/client:/usr/java/j2sdk1.4.0/jre/lib/i386;
and displayed this:
Java version=1.4.0-beta
Java vendor=Sun Microsystems Inc.
OS=Linux 2.4.3-12 on i386
Wednesday, February 27, 2002 at 3:29:02 AM India Standard Time
But following was added to apache 2.0 error_log:

THIRD TIME
------------
Then I made a distclean in php-4.1.1 directory. stopped apache 2.0.
Removed directory /wwwroot/php. And configured and installed php with
following options..
------------------------------PHP 4.1.1 Configure---------------------
./configure --prefix=/wwwroot/php --with-apxs2=/wwwroot/bin/apxs
--with-mod_charset --with-config-file-path=/wwwroot/php/ --with-openssl

--enable-track-vars --enable-overload --with-mcrypt
--with-java=/usr/java/j2sdk1.4.0 --enable-sysvsem --enable-sysvshm
This time when I restarted apache 2.0 php didn't work and lynx exited
with
same Unknown network error message. Following was added to apache
logs/error_log
[Wed Feb 27 19:44:25 2002] [notice] Digest: done
