Current status

Targeted release: Fedora 25
Last updated: 2016-09-11
Tracker bug: #1353500

Most of the work is done in my personal repository, see php70 repository for Fedora 24

PHP version 7.0.8 build in rawhide June 27th.

Detailed Description

Update the PHP stack in Fedora to latest version 7.0.x, which brings a big performance improvement.

PHP 7.0.0 was released in December 2015.
PHP 7.1.0 is planed for end of year, but is probably not compatible with our Schedule, will probably be a Fedora 26 feature

Compatibility for PHP code is very good, while internal API have big changes, implying a major rewrite of C extensions.

Benefit to Fedora

Provides the latest PHP version to developers and system administrators. Especially a great performance boost have been confirmed by various projects (running big web site), around 50% saved, time and memory.

Some other distributions already provides this version, upgrade have been differed in Fedora to give time to projects using PHP to fix compatibility.

This will be an opportunity to clean (remove) old packages, not compatible and unmaintained upstream.

Scope

Proposal owners: Check Koschei status. Test with latest version to ensure compatibility. Work with upstream on bug fixing.

Other developers: all PHP package owners: test with latest version to ensure compatibility. Work with upstream on bug fixing.

Release engineering: needed mass rebuild (C extensions) done but change owner.

Policies and guidelines: N/A (not affected by this Change)

Trademark approval: N/A (not needed for this Change)

Upgrade/compatibility impact

Status of compatibility for C extensions: see PECL extensions status

Not yet compatible extensions are probably dead projects:

php-pecl-cairo
php-pecl-gearman
php-pecl-jsonc (replaced by php-json which is now under a "free" license) => dropped
php-pecl-judy
php-pecl-krb5
php-magickwand (upstream states this project is deprecated, and recommends php-pecl-imagick)
php-pecl-memprof
php-pecl-mongo (replaced by new driver php-pecl-mongodb, and the php-mongodb library, both are under review) => dropped
php-pecl-mysqlnd-ms => dropped
php-pecl-mysqlnd-qc => dropped
php-pecl-ncurses
php-pecl-parsekit
php-pimple (by disabling the extension, keeping the pure-php library, without its accelerator)
php-pecl-runkit
php-twig (by disabling the extension, keeping the pure-php library, without its accelerator)
php-xcache (php-opcache is the official opcode cache, maintained by the PHP project, APCU for user data cache) => dropped
php-pecl-xhprof => dropped

New packages needed:

php-pecl-mongodb (the new driver), review #1269056
php-mongodb (the library), review #1276834
php-alcaeus-mongo-php-adapter (a compatibility library), review #1347147
php-pecl-apcu-bc (the APC compatibility layer for php-pecl-apcu), review #1350148

How To Test

The PHP stack (extensions and libraries) are monitored by Koschei, see the Koschei PHP group

install and play with your web applications

User Experience

Developers and system administrators will have the great benefit or running the latest PHP version.

Dependencies

All php-* packages (and some *-php)

Contingency Plan

Contingency mechanism: Drop not compatible packages
Contingency deadline: Beta
Blocks release? No (broken packages will be proposed for removal)
Blocks product? N/A
