RFE: php should provides "Zend Module Api No"
Last modified: 2007-11-30 17:11:46 EST
Description of problem: php only provide "PHP Api Version" (php-api). This value still the same across version, while "Zend Module Api No" change. At load time, php check "Zend Module Api Version". For example, when trying to load a extension, build with php-5.2.0, on php-5.1.6, a sanity check refuse to load the extension # php -v PHP Warning: PHP Startup: mailparse: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=0 PHP compiled with module API=20050922, debug=0, thread-safety=0 These options need to match I think it would be better to handle this with Requires/Provides in the RPM spec file. For exemple, in php.spec %define zendver 20050922 ... Provides: php-zendapi = %{zendver} ... vzend=$(sed -n '/#define PHP_API_VERSION/{s/.* //;p}' main/php.h) if test "x${vzend}" != "x%{zendver}"; then : Error: Upstream Zend Module API version is now ${vapi}, expecting %{apiver}. : Update the zendver macro and rebuild. exit 1 fi And in a pecl extension specfile : %global php_zendver %((echo 0; php -i 2>/dev/null | sed -n 's/^PHP Extension => //p') | tail -1) ... Requires: php-zendapi = %{php_zendver} There is also "Zend Extension Api No" (220051025), but i don't know when this value is used. Regards.
I saw version 5.2.0-4 is on rawhide, great. This provides php-zend-abi = "Zend Extension Api No" Why not the "Zend Module Api No" (ZEND_MODULE_API_NO define in Zend/zend_modules.h) as the check seems made on this value. I must apologize, my example int the bug report was not correct (don't search for the good value). sed -n '/#define PHP_API_VERSION/{s/.* //;p}' main/php.h 20041225 sed -n '/#define ZEND_MODULE_API_NO/{s/.* //;p}' Zend/zend_modules.h 20060613 sed -n '/#define ZEND_EXTENSION_API_NO/{s/^[^0-9]*//;p;}' Zend/zend_extensions.h 220060519 Regards.
I confirm that it's ZEND_MODULE_API_NO which is first needed. Each pecl extension include an "zend_module_entry" object. Second member is "zend_api". Value is ZEND_MODULE_API_NO (included in STANDARD_MODULE_HEADER). ext/standard/php_dl.c (in function php_dl) check this value. > module_entry->zend_api != ZEND_MODULE_API_NO Same safety check is done in ./Zend/zend_extensions.c with ZEND_EXTENSION_API_NO, but i don't find any extension using a "extension_version_info".
php-5.1.6-3.2.fc6 has been pushed to FC6 updates-testing, which should contain the fix for this bug. You can test the new packages by running: # yum --enablerepo=updates-testing update php
Have you more information about ZEND_MODULE_API_NO vs ZEND_EXTENSION_API_NO (comment #2) ? I've also test php-5.2.0-7 from rawhide. Providing /etc/rpm/macros.php is really a good idea. Regards
Ah, good catch Remi, you're correct, thanks, I'll fix that.
Well, After the Fedora Extras Packaging Commitee, members wants to be consistent with other langages virtual provides. : ruby(abi) python(abi) ... Can you update php to provide : Provides: php-api = %{apiver}, php(api) = %{apiver}, php(zend-abi) = %{zendver} (php-api is used for a very long time, php(..) will be used for packaging guidelines) Can you also add the macros.php to FC-6 version ? Regards
Can you file new bugs for those two requests, and include a link to the Packaging discussion for the first issue? This bug is being used to track too much :)
Dear Sirs WE have the same problem, php-mysql package was compiled with diferent API than php package. I can't find any newer package than php-mysql-5.2.0-8.x86_64.rpm that returns the error message Unable to initialize module\nModule compiled with module API=20050922, debug=0, thread-safety=0\nPHP compiled with module API=20060613, debug=0, thread-safety=0\nThese options need to match\n in Unknown on line 0 Please can you give us information if this error was solved in any package for x86_64 architecture. Thank You Raul Drelichman (raul@drelichman.com)
Raul, php-mysql requires exact version of php-common. You shouldn't have this issue (which is pecl extension related). It seems you have installed php-myql with --nodeps or --force option with php-5.1.6 installed.
Remi: Thanks. No, I installed the modules in the correct order, i.e., in frst time php-common 5.2.0.-8 (and first the modules needed by this i rememeber php-cli also) then php 5.2.0.-8 and the last one php-mysql 5.2.0.-8 without use the --force or --nodeps options. Do you consider that I need to do a clean install of all. uninstaling all the modules and reinstaling from zero? Thank again for giving your experience to us Raul Drelichman
