ID: 15702 Updated by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] -Status: Feedback +Status: Open Bug Type: Java related Operating System: Red Hat Linux 7.1 PHP Version: 4.1.1 New Comment:
I have generated backtrace this time which showed that problem was related to mutex.c. I used Apache 2.0 because there was also a problem in swf.c which resulted in segmentation fault when using Apache 2 only not Apache 1.3. After I removed --with-swf from configure Apache and php worked fine. I have also submitted that bug report. Then I decided to find the source of segmentation fault caused by Java extension. This time I used --enable-debug configure option and Apache 2 beta (Apache 2_0_28) and compiled php 4.1.1 as Apache shared module (libphp4.so). - ---------------------------APACHE 2_0_28-------------------------- ./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-apxs2=/wwwroot/bin/apxs --with-mod_charset --with-config-file-path=/wwwroot/php/ --with-openssl --with-zlib --enable-bcmath --with-bz2 --enable-calendar --with-cpdflib --with-png-dir --with-jpeg-dir --with-tiff-dir --enable-ctype --with-curl --with-db3 --with-dom --enable-exif --enable-filepro --enable-ftp --with-gd --enable-gd-native-ttf --with-xpm-dir --with-freetype-dir=/usr --with-ttf --with-t1lib --with-gettext --with-gmp --with-hyperwave --with-iconv --with-imap --with-kerberos --with-imap-ssl --with-ircg --with-ldap --enable-mbstring --enable-mbstr-enc-trans --with-mcal=/usr/src/libmcal --with-mhash --with-mnogosearch=/usr/local/mnogosearch --with-mysql --with-pgsql --with-pspell --with-qtdom --enable-trans-sid --enable-shmop --with-snmp -enable-ucd-snmp-hack --enable-sockets --with-regex=php --enable-wddx --with-expat-dir=/usr/local --enable-xslt --with-xslt-sablot --with-yaz=/usr/local/lib --enable-yp --with-zip --with-pdflib --enable-versioning --with-tsrm-st --with-tsrm-pthreads --enable-track-vars --enable-overload --with-mcrypt --with-Java=/usr/Java/j2sdk1.4.0 --enable-sysvsem --enable-sysvshm --enable-debug ------------------------------------------------------------------------ Apache and php worked well no segmentation fault etc. But Java didn't work.

My configuration is RedHat Linux 7.1, apache_1.3.23, php-4.1.1 and Jdk1.4 beta 2. I must mention here that earlier php versions 4.0.6 (or earlier) and jdk1.2.2 worked without any problems (and without exporting LD_LIBRARY_PATH With php 4.1.1 and jdk1.4, I faced many problems: ***************************************Results with Apache 1.3.23********************** I first tried to compile php and apache with almost all options available as below: /////////////////////////////////////PHP//////////////////////////////////// ./configure --prefix=/wwwroot/php --with-apache=/usr/src/apache_1.3.23 --with-mod_charset --with-config-file-path=/wwwroot/php/ --with-openssl --with-zlib --enable-bcmath --with-bz2 --enable-calendar --with-cpdflib --with-png-dir --with-jpeg-dir --with-tiff-dir --enable-ctype --with-curl --with-db3 --with-dom --enable-exif --enable-filepro --enable-ftp --with-gd --enable-gd-native-ttf --with-xpm-dir --with-freetype-dir=/usr --with-ttf --with-t1lib --with-gettext --with-gmp --with-hyperwave --with-iconv --with-imap --with-kerberos --with-imap-ssl --with-ircg --with-ldap --enable-mbstring --enable-mbstr-enc-trans --with-mcal=/usr/src/libmcal --with-mhash --with-mnogosearch=/usr/local/mnogosearch --with-mysql --with-pgsql --with-pspell --with-qtdom --enable-trans-sid --enable-shmop --with-snmp -enable-ucd-snmp-hack --enable-sockets --with-regex=php --with-swf --enable-wddx --with-expat-dir=/usr/local --enable-xslt --with-xslt-sablot --with-yaz=/usr/local/lib --enable-yp --with-zip --with-pdflib --enable-versioning --with-tsrm-st --with-tsrm-pthreads --enable-track-vars --enable-overload --with-mcrypt --with-java=/usr/java/j2sdk1.4.0 --enable-sysvsem --enable-sysvshm --with-xmlrpc ////////////////////////////////////////APACHE//////////////////////////////////// ./configure --prefix=/wwwroot --activate-module=src/modules/php4/libphp4.a --with-perl=/usr/bin/perl --enable-module=auth_anon --enable-module=auth_dbm --enable-module=auth_db --enable-module=auth_digest --enable-module=cern_meta --enable-module=example --enable-module=expires --enable-module=headers --enable-module=info --enable-module=log_agent --enable-module=log_referer --enable-module=mime_magic --enable-module=mmap_static --enable-module=proxy --enable-module=rewrite --enable-module=so --enable-module=speling --enable-module=unique_id --enable-module=usertrack --enable-module=vhost_alias //////////////////////////////////////////////////////////////////////////////////// No libphp_java.so was created with these options under /usr/src/php-4.1.1/modules or under /usr/src/php-4.1.1/ext/java and only libphp_java.a was created. Under /wwwroot/php/lib/php/20010901 also only libphp_java.a was installed after make install. Then thinking that java support might have been built in with this version. I tried to access sample jver.php file. But message, unable to create instance of non-existing class etc. was displayed. Then I tried to compile php with only --with-apache=/usr/src/apache_1.3.23 and --with-java=/usr/java/j2sdk1.4.0 options and this time libphp_java.so was created. But java didn't work (even after enabling [java] in php.ini and exporting LD_LIBRARY_PATH as mentioned below). I wanted to enable other php options so I deleted apache and php source and install directories and tried to install php again as apache shared module (libphp4.so) with following options //////////////////////////////PHP//////////////////////////////////// ./configure --prefix=/wwwroot/php --with-apxs=/wwwroot/bin/apxs --with-mod_charset --with-config-file-path=/wwwroot/php/ --with-openssl --with-zlib --enable-bcmath --with-bz2 --enable-calendar --with-cpdflib --with-png-dir --with-jpeg-dir --with-tiff-dir --enable-ctype --with-curl --with-db3 --with-dom --enable-exif --enable-filepro --enable-ftp --with-gd --enable-gd-native-ttf --with-xpm-dir --with-freetype-dir=/usr --with-ttf --with-t1lib --with-gettext --with-gmp --with-hyperwave --with-iconv --with-imap --with-kerberos --with-imap-ssl --with-ircg --with-ldap --enable-mbstring --enable-mbstr-enc-trans --with-mcal=/usr/src/libmcal --with-mhash --with-mnogosearch=/usr/local/mnogosearch --with-mysql --with-pgsql --with-pspell --with-qtdom --enable-trans-sid --enable-shmop --with-snmp -enable-ucd-snmp-hack --enable-sockets --with-regex=php --with-swf --enable-wddx --with-expat-dir=/usr/local --enable-xslt --with-xslt-sablot --with-yaz=/usr/local/lib --enable-yp --with-zip --with-pdflib --enable-versioning --with-tsrm-st --with-tsrm-pthreads --enable-track-vars --enable-overload --with-mcrypt --with-java=/usr/java/j2sdk1.4.0 --enable-sysvsem --enable-sysvshm --with-xmlrpc ///////////////////////////////////APACHE/////////////////////////////////////// ./configure --prefix=/wwwroot --with-perl=/usr/bin/perl --enable-module=auth_anon --enable-module=auth_dbm --enable-module=auth_db --enable-module=auth_digest --enable-module=cern_meta --enable-module=example --enable-module=expires --enable-module=headers --enable-module=info --enable-module=log_agent --enable-module=log_referer --enable-module=mime_magic --enable-module=mmap_static --enable-module=proxy --enable-module=rewrite --enable-module=so --enable-module=speling --enable-module=unique_id --enable-module=usertrack --enable-module=vhost_alias This time libphp_java.so was created and installed. I enabled java support in php.ini as below: [Java] java.home=/usr/java/j2sdk1.4.0:/wwwroot/htdocs java.class.path=/wwwroot/php/lib/php/php_java.jar extension_dir=/wwwroot/php/lib/php/20010901 extension=libphp_java.so java.library=/usr/java/j2sdk1.4.0/jre/lib/i386/client/libjvm.so With above options libphp_java.so was shown as loaded by phpinfo(). When I tried to access that sample file provided with java extension (jver.php) it produced error that libjvm.so was unable to load libjava.so. Then I exported LD_LIBRARY_PATH as: export LD_LIBRARY_PATH=/usr/java/j2sdk1.4.0/jre/lib/i386/native_threads:/usr/java/j2sdk1.4.0/jre/lib/i386:/usr/java/j2sdk1.4.0/jre/lib/i386/client; Then I restarted apache from same shell in which I exported LD_LIBRARY_PATH. This time when I accessed jver.php browser sent the request and just waited and waited and then exited with some message like network error etc. I had enabled php error logging but nothing was entered in that file. Then when I looked at apache error_log I found so segmentation fault produced by php: ////////////////////////////////////////////////////////////////////////////// [Sat Feb 23 20:51:09 2002] [notice] Digest: generating secret for digest [Sat Feb 23 20:51:48 2002] [notice] child pid 704 exit signal Segmentation fault (11) [Sat Feb 23 20:52:55 2002] [notice] child pid 703 exit signal Segmentation fault (11) [Sat Feb 23 20:53:22 2002] [notice] child pid 706 exit signal Segmentation fault (11) // errors produced by php authentication ... ///////////////////////////////////////////////////////////////////////////////// Then I accessed jver.php again and these messages increased in apache error_log. I knew these errors were due to some problem in php. But I don't know what is the problem. I changed java settings in php.ini as below but it still didn't work and same error ("network error and segmentation fault in apache error_log") ///////////////////////////////////////////////////////// [Java] java.home=/usr/java/j2sdk1.4.0:/wwwroot/htdocs java.class.path=/wwwroot/php/lib/php/php_java.jar extension_dir=/wwwroot/php/lib/php/20010901 extension=libphp_java.so java.library=/usr/java/j2sdk1.4.0/jre/lib/i386/libjava.so // this was changed /////////////////////////////////////////////////////////////////////////////// ------With JDK 1.2.2 it worked------------------------------------ Then thinking that there might be problem with Jdk1.4, I installed Jdk1.3 and then Jdk1.2.2. With Jdk1.2.2 I compiled every thing again from beginning and configure options changed to --with-apache=/usr/src/apache_1.3.23 and --with-java changed according to jdk1.2.2 paths. libphp_java.so was produced this time. When jver.php was accessed this time errors were about unable to find libjvm.so and other libs etc. I exported LD_LIBRARY_PATH with paths of Jdk1.2.2 and restarted apache. Finally this time it worked and Java Version was displayed. I added this export to /root/.bashsrc and then to /etc/profile and finally in /etc/httpd start function but this variable wasn't set and I had to manually export LD_LIBRARY_PATH every time and then restart apache only then java worked. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15702&edit=1
