This was a pretty big year for the Miro project and the first year for
the Miro Community project. In Miro-land, we pushed out Miro 2.0 which
was a complete re-write of the user interface. Then we pushed out Miro
2.5 which was a rewrite of the storage/database layer. We also switched
from svn to git. That's three really big changes for a single project
in one year.
Miro 2.5 was a messy release and we've made a bunch of changes so we
don't have to go through that again. We've been spending time on the
unit test, QA automation, and code quality for Miro 2.6. We've changed
the release process so that it buffers more time to catch issues.
We're doing more peer review of complex code changes. The switch to git
will help since branching and merging are much easier and less error-prone.

"Opened reports at end of year" is the total number of opened bugs at the end
of that year. So at the end of 2007, we had 453 open bugs. At the end of
2008, we had 705 open bugs, ...
I wasn't sure whether to include 2007 or not since half way through that year
we switched from Trac to Bugzilla. No one needed to create an account in
Trac, so user numbers should be lower. Also, we were getting a lot of Trac
spam, so comment, opened and closed numbers were much higher.

I thought this was an interesting data set.
The INCOMPLETE status was added mid-2008. We use this for whenever we ask a
user for some information that we need to work on a bug and the user never gets
back to us. It's better than marking it as INVALID or WORKSFORME since it's
easier to find this set of bugs that were pushed to the side because need
We're fixing on average 3 bugs a day--that's pretty impressive.

non-PCF people in this list, Uwe is the Debian packager for Miro and Pan is
an OpenSUSE packager for Miro. sg and Keith Lard both run OSX.

Moving along, I can now get stats out of our git repository. git ftw!
In 2009, we did 11 releases (22 releases if you include release candidates)
of which 2 were MASSIVE code overhaul releases. Miro 2.0 involved a re-write
of the user interface using native widgets which resulted us in dropping
4,000 files from the codebase (a large portion of that was probably
locale-related). Miro 2.5 involved a re-write of the database layer. We
had a lot of bug fix releases to stabilize things after these two big releases.

Half of the 2.0 work and all of the 2.5 work was done in 2009. 2.0 was
clearly a monumental release like no other release we've ever done.
In 2009, we did 1,382 commits. For comparison, we did 2,049 commits in 2008.
The bulk of the work for Miro 2.0 was done at the end of 2008--I think that
accounts for the large discrepancy here.
I don't have stats for testing contributions or translation contributions
so I can't speak to those. I can only speak to patches and bug triage
In 2009, we had 19 contributed fixes/features. PCF employees are doing the
bulk of the work. This is still an area we could use help with.
In 2009, we've done a lot to lower the barriers to entry and make this easier:
improved code quality, wrote documentation, improved build documentation,
improved build scripts, added unit tests, ... In 2010, we're continuing this
Despite the Miro 2.5 release which was pretty rocky, I think we had a really
good year and got a lot accomplished. I'm looking forward to Miro 2.6 (or
whatever the next release gets called).
I'd love to see more contributions from other people. If you have some free
time or some passion and want to help out, let me know. If you don't have
free time, but have some spare change floating around, please donate--this
helps PCF pay for employees to work on Miro.
