PHP IDE :: NuSphere Forums :: View topic - [resolved] pls confirm dbg WILL NOT wrk with zts.

Posted: Mon May 26, 2008 7:15 pm

I have loaded the correct dbg modules to my server (confirmed that my Linux server is running glibc 2.3.4)

I have installed the dbg-wizard.php in my public_html dir

I my custom php.ini, I have added

Code:

extension_dir=/home/USERNAME/extensions

(because this is a shared server and I don't have access to /usr/lib/php/extensions/no-debug-zts-20060613, the default extension location)

I am being told from dbg-wizard that 'DBG (PHP DEBUGGER) is NOT INSTALLED':

* PHP Version: 5.2.5
* Web Server: Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.7a mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635
* Server Name: USERNAME.com
* OS: Linux
* Your Client IP Address: XX.XXX.XXX.XX
* Your Server IP Address: XX.XXX.XXX.XX
* Port: 80
* Your Web Server and PhpED are on different machines
* Path to website files: /home/USERNAME/public_html/
* Document Root is: /home/USERNAME/public_html/
* Your PHP.INI file is /home/USERNAME/platform/php.ini
* PHP extensions directory is /home/USERNAME/extensions
* DBG (PHP DEBUGGER) is NOT INSTALLED

I followed the instructions from the paragraph 'How to install Server side DBG module'

Code:

[debugger]
debugger.enabled=on
debugger.profiler_enabled=on
debugger.hosts_allow=host1 host2 host3
debugger.hosts_deny=ALL
debugger.ports=7869, 10000/16

[Zend]

zend_optimizer.optimization_level=15
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.2.0
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.2.0
zend_optimizer.version=3.2.0

zend_extension_ts=/home/USERNAME/extensions/dbg.so-5.2.x

zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

I have tried several iterations with the zend_extension_ts in different places.
I even try putting in nonsense file names (e.g. dbg.so-5.2.y) , and I don't get errors in my log file

HOWEVER if I use the glibc 2.7 version of the file, I get a core dump every time I try the correctly named 2.7 version (so, the file is getting read)

PHP Configure Command:

Code:

'./configure' '--enable-bcmath' '--enable-calendar' '--enable-dbase' '--enable-exif' '--enable-fastcgi' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-magic-quotes' '--enable-maintainer-zts' '--enable-mbstring' '--enable-pdo=shared' '--enable-soap' '--enable-sockets' '--enable-wddx' '--enable-zip' '--prefix=/usr' '--with-bz2' '--with-curl=/opt/curlssl/' '--with-curlwrappers' '--with-freetype-dir=/usr' '--with-gd' '--with-gettext' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libexpat-dir=/usr' '--with-libxml-dir=/opt/xml2' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mhash=/opt/mhash/' '--with-mime-magic' '--with-mysql=/usr' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--with-mysqli=/usr/bin/mysql_config' '--with-openssl=/usr' '--with-openssl-dir=/usr' '--with-pdo-mysql=shared' '--with-pdo-sqlite=shared' '--with-png-dir=/usr' '--with-pspell' '--with-sqlite=shared' '--with-tidy=/opt/tidy/' '--with-ttf' '--with-xmlrpc' '--with-xpm-dir=/usr/X11R6' '--with-xsl=/opt/xslt/' '--with-zlib' '--with-zlib-dir=/usr'

I don't seem to get any errors in my error_log. Any suggestions?

Other phpinfo() settings:

Code:

Server API CGI/FastCGI
Virtual Directory Support enabled
Configuration File (php.ini) Path /usr/lib
Loaded Configuration File /home/USERNAME/platform/php.ini
PHP API 20041225
PHP Extension 20060613
Zend Extension 220060519
Debug Build no
Thread Safety enabled
Zend Memory Manager enabled
IPv6 Support enabled
Registered PHP Streams zip, php, file, data, tftp, ftp, telnet, dict, ldap, http, https, ftps, compress.bzip2, compress.zlib

Registered Stream Filters string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, convert.iconv.*, bzip2.*, zlib.*

Looks like Thread Safety is enabled - I ran across a post that indicated this can be problematic. Is this my issue?

In desperation, I even commented out the existing Zend ts lines and tried putting this into my php.ini:

Code:

extension=dbg.so-5.2.x;

At least this kicks me an error (=more information):

Code:

[28-May-2008 11:36:02] PHP Warning: PHP Startup: Unable to load dynamic library '/home/USERNAME/extensions/dbg.so-5.2.x' - /home/USERNAME/extensions/dbg.so-5.2.x: undefined symbol: compiler_globals in Unknown on line 0

Again, my assumption is that this has something to do with thread safety. ANYONE have ANY ideas?

We think the problem is because you are using
--enable-maintainer-zts'

Please try recompiling w/o it. Thanks!

1st - thanks for the response.

Is there a php.ini setting that disables --enable-maintainer-zts?

Again - I am using a SHARED server - not gonna be able to easily recompile with the options I like.

Thanks in advance,

Kevin,

You're right. You don't need zts under any linux/unix until want to get troubles with stability in almost all php extensions. Although the extensions themselves are threadsafe, it's known that only a few of them are using thread-safe 3rd party libraries.
Don't forget to run make clean or better unpack fresh php sources before running configure without zts argument.

Regarding php settings, no zts can't be turned off after php is compiled. It's a compile-time switch that changes php binary in many ways.

Thanks - that was all I was looking for.
