Proposed Changes to PHP Guidelines
Synopsis
This page describes items that need to be changed in the PHP Guidelines or other items that need to be reviewed or ratified by the Fedora Packaging Comittee and FESCo .
Actual Guidelines
File Placement
Non-PEAR PHP extensions should put their Class files in /usr/share/php.
Change proposal
File Placement
Non-PEAR PHP extensions should put their Shared Class files in a subfolder of /usr/share/php.
Actual Guidelines
Requires and Provides
PECL Packages
A PECL package MUST have:
BuildRequires: php-devel, php-pear
Requires(post): %{__pecl}
Requires(postun): %{__pecl}
%if %{?php_zend_api}0
Requires: php(zend-abi) = %{php_zend_api}
Requires: php(api) = %{php_core_api}
%else
Requires: php-api = %{php_apiver}
%endif
Provides: php-pecl(foo) = %{version}
Change proposal
Requires and Provides
C extensions (PECL and others)
Each C extension instantiate a zend_module_entry with the ZEND_MODULE_API_NO constant. PHP check that the value for the extension is egal to the value for PHP (standard ABI check).
A C extension MUST have:
BuildRequires: php-devel
%if %{?php_zend_api}0
Requires: php(zend-abi) = %{php_zend_api}
Requires: php(api) = %{php_core_api}
%else
Requires: php-api = %{php_apiver}
%endif
Condition around Requires could be removed if the extension requires php >= 5.2.0, where php_zend_api always defined. (so it is mandatory for EPEL package)
PECL Packages
PECL extension MUST have ABI check (see previous)
A PECL package MUST also have:
BuildRequires: php-pear
Requires(post): %{__pecl}
Requires(postun): %{__pecl}
Provides: php-pecl(foo) = %{version}
Actual Guidelines
Macros and scriptlets
PECL Modules
The php-pear package in Fedora Core 5 and above (version 1:1.4.9-1.2) provides several useful macros:
- %{pecl_phpdir}
- %{pecl_docdir}
- %{pecl_testdir}
- %{pecl_datadir}
- %{pecl_xmldir}
You may need to define a few additional macros to extract some information from PHP. It is recommended that you use the following:
%global php_apiver %((echo 0; php -i 2>/dev/null | sed -n 's/^PHP API => //p') | tail -1)
%{!?__pecl: %{expand: %%global __pecl %{_bindir}/pecl}}
%{!?php_extdir: %{expand: %%global php_extdir %(php-config --extension-dir)}}
And here are some recommended scriptlets for properly registering and unregistering the module:
%if 0%{?pecl_install:1}
%post
%{pecl_install} %{pecl_xmldir}/%{name}.xml >/dev/null || :
%endif
%if 0%{?pecl_uninstall:1}
%postun
if [ $1 -eq 0 ] ; then
%{pecl_uninstall} %{pecl_name} >/dev/null || :
fi
%endif
Change proposal (just add a comment)
Condition around the post/postun scriplet can be removed if the extension requires php >= 5.2.0, where pecl_install always defined. (so it is mandatory for EPEL package)
