Mercurial 2.3 sprint, Day 1-2-3

2012/05/15 by Pierre-Yves David

I'm now back from Copenhagen were I attended the mercurial 2.3 sprint with twenty other people. A huge amount of work was done in a very friendly atmosphere.

Regarding mercurial's core:

  • Bookmark behaviour was improved to get closer to named branch's behaviour.
  • Several performance improvements regarding branches and heads caches. The heads cache refactoring improves rebase performance on huge repository (thanks to Facebook and Atlassian).
  • The concept I'm working on, Obsolete markers, was a highly discussed subject and is expected to get partly into the core in the near future. Thanks to my employer Logilab for paying me to work on this topic.
  • General code cleanup and lock validation.

Regarding the bundled extension :

  • Some fixes where made to progress which is now closer to getting into mercurial's core.
  • Histedit and keyring extensions are scheduled to be shipped with mercurial.
  • Some old and unmaintained extensions (children, hgtk) are now deprecated.
  • The LargeFile extension got some new features (thanks to the folks from Unity3D)
  • Rebase will use the --detach flag by default in the next release.

And I'm probably forgetting some stuff. Special thanks to Unity3D for hosting the sprint and providing power, network and food during these 3 days.


Mercurial 2.3 day 0

2012/05/10 by Pierre-Yves David

I'm now at Copenhagen to attend the mercurial "2.3" sprint.

About twenty people are attending, including staff from Atlassian, Facebook, Google and Mozilla.

I expect code and discussion about various topic among:

  • the development process of mercurial itself,
  • performance improvement on huge repository,
  • integration of Obsolete Markers into mercurial core,
  • improvement on various aspect (merge diff, moving some extension in core, ...)

I'm of course very interested in the Obsolete Markers topic. I've been working on an experimental implementation for several months. An handful of people are using them at Logilab for two months and feedback are very promising.
