HOLLAND, Michigan - The Perl Foundation has migrated Perl 5 to the Git
version control system, making it easier than ever for Perl's development
team to continue to improve the language that powers many websites.
Moving from Perforce to git provides a number of benefits to the Perl
- With a public repository and Git's extensive support for distributed
and offline work, working on Perl 5's source becomes easier for everyone
- Because Git is open source, all developers now have equal access to
the tools required to work on Perl's codebase.
- Core committers have less administrative work to do when integrating
- Developers outside the core team can more easily work on experimental
changes to Perl before proposing them for inclusion in the next release.
- A vast array of improved repository and change analysis tools are now
available to Perl's developers.
- The new Git repository includes every version of Perl 5 ever released,
as well as every revision made during development.

In true open source style, Sam Vilain converted Perl's history from
Perforce to Git. He did the work both in his spare time and in time
donated by his employer, Catalyst IT. He spent more than a year building
custom tools to transform 21 years of Perl history into the first
ever unified repository of every single change to Perl. In addition
to changes from Perforce, Sam patched together a comprehensive view
of Perl's history incorporating publicly available snapshot releases,
changes from historical mailing list archives and patch sets recovered
from the hard drives of previous Perl release engineers.
Perl 5 is used by businesses around the world including the BBC,
Amazon.com, LiveJournal, Ticketmaster, Craigslist and IMDb. Larry Wall
created Perl in 1987 while working as a systems administrator for NASA.
Larry released Perl 1.000 on December 18th 1987. Over the past 21 years,
Perl has grown into a high-level, general-purpose, dynamic programming
language and is widely used for Web development, Systems Administration,
Genomics and in many other disciplines. The most recent major version
of Perl 5 (5.10.0) was released one year ago.
Git is an open source version control system designed to handle very
large projects with speed and efficiency. Created by Linus Torvalds,
the inventor of Linux to handle the vast number of contributions to
the Linux Kernel, Git is highly flexible and extensible. Perl's motto,
"There's More Than One Way To Do It!" perfectly matches the Git workflow.
Nicholas Clark, the manager for Perl 5.8.9 which was released this week,
said "I'm looking forward to Git giving me the ability to work either
online or offline. Perforce is great when I have a network connection,
but until now those times when I've been trying to develop on trains
or planes, at stations or airports, I'm back in the 'dark ages' before
version control. Git solves this problem and more".
The hardware behind this and the systems administration time to maintain
it is donated by Booking.com. Booking.com has also recently donated
$50,000 to The Perl Foundation, to aid in the further development and
maintenance of the Perl programming language in general, and Perl 5.10
Perl originally used the Revision Control System (RCS) until March
1997 when it switched to the Perforce Software Configuration Management
System. The Perforce repository was graciously hosted and maintained,
free of charge, by ActiveState. Perforce provided the core developers
with powerful tools, but these tools were not available to users outside
the core team. The switch to Git removes this barrier.
