In addition to this, several modules do not work with the new PHP yet. Among them is of course the suhosin extension but also APC and xdebug. The state of other extensions still needs to be researched; if you are lucky simply recompiling will do it.
While I obviously cannot recommend the use of PHP 5.4.0 on any server or production system yet, I would consider it a good idea to start testing your setup and scripts for compatibility. Also at Arch we like to play with the newest features and get hit by bugs nobody has seen before.
Therefore I set up a repository for all administrators and developers who like their packages broken. These come without suhosin (patch nor extension) and are available for both i686 and x86_64. I also packaged some modules like memcache(d), apc and geoip. Note that I will base these builds upon the [testing] repository. This might not be a problem right now, but once you see a our stock version of PHP in [testing] these package wont work without the usage of [testing] as well.
To use this repo put the following lines on top of all other repositories (including [testing]) in pacman.conf:
[php] Server = https://repo.pierre-schmitz.com/$repo/os/$arch
For those who are all over the brand new signing stuff: Yes, all these packages are signed using my Arch packager key.
Before you get started have a brief look at the changelog and migration guide which are provided upstream. Then make sure you get all changes in php.ini merged. The easiest was to do so is probably starting with the packaged one and adjust the changes you need. For testing properly it is important to enable error reporting:
error_reporting = E_ALL display_errors = On display_startup_errors = On
Note that E_ALL now also includes E_STRICT by default. If you are testing third party code make sure it does not override these settings by either .htaccess or calling error_reporting(). If you find any error this way: You know the drill, report it to the upstream projects.
If you have any suggestions about the packages or configuration, let me know. Especially drop a line if you found any issues regarding extensions or web apps. It’ll help me a lot to know how many breakage such an update will cause.
