Hello all, I just (mostly) finished up some work on Launchpad on behalf of the team at Canonical who work on the Ubuntu Software Center.
While doing that work, I got really interested in how many lines of code were being added or removed by a particular branch or commit as I didn't want to go against LP's lines-of-code neutrality policy. Thus, I wrote a simple little Bazaar plugin that can give you quick answers. I've mentioned it on IRC to a few of you, but Rob suggested I send an email. Get the plugin from lp:bzr-damage in the usual way. In one branch,:: $ bzr damage Damage: 28 lines of code In another,:: $ bzr damage Healing: 39 lines of code That will show you how many lines of code you are inflicting if you land that branch. There's also a command, 'bzr loc', that takes mostly the same arguments as 'bzr log', but shows the lines of code in each revision, and shows the actual author rather than PQM. e.g.:: $ bzr loc --limit 10 15429: Jonathan Lange 2012-06-15 -48 [merge] [r=stub][bug=1006295] Remove support code to handle two different 15428: William Grant 2012-06-15 +9 [merge] [r=wgrant][no-qa] Merge db-stable r11680. 15427: William Grant 2012-06-15 -298 [merge] [r=wgrant][bug=1009370][no-qa] Drop unused 15426: Ian Booth 2012-06-15 -13 [merge] [r=wgrant][bug=1009358, 15425: Brian Murray 2012-06-15 +35 [merge] [r=wallyworld][bug=826854] [r=wallyworld][bug=826854] add a 15424: Ian Booth 2012-06-15 +14 [merge] [r=wallyworld][bug=1012912] The filebug page safely ignores missing 15423: Ian Booth 2012-06-15 -229 [merge] [r=wgrant][no-qa] Delete RemoveGranteeSubscriptionJob since it's now 15422: Curtis Hovey 2012-06-14 +87 [merge] [r=jcsackett][bug=1012808] Register the commercial email job sources 15421: Graham Binns 2012-06-14 +1 [merge] [r=jcsackett][bug=682771][no-qa] Launchpad now depends on 15420: Ivo Kracht 2012-06-14 -5 [merge] [r=jcsackett][bug=999662] [r=jelmer][bug=999662] Package information Total damage: -447. Finally, there's 'bzr high-scores', which shows each author over the given revision range, ranked by how many lines of code they've removed. <http://paste.ubuntu.com/1039164/> is a slightly stale run of the rankings since the policy was introduced. <http://paste.ubuntu.com/1040992/> are the rankings for the same time period before the policy. For the link shy, here are the top 5:: 1. Aaron Bentley <aa...@canonical.com> -6410 2. Colin Watson <cjwat...@canonical.com> -2330 3. William Grant <william.gr...@canonical.com> -1984 4. Curtis Hovey <curtis.ho...@canonical.com> -1743 5. Robert Collins <robe...@robertcollins.net> -1395 I would also draw everyone's attention to cjwatson's loc-contributions in lp:lp-dev-utils, which will tell you the score for an individual contributor. The code lives at lp:bzr-damage. Everyone in ~canonical has commit access but please, file MPs. I haven't yet filed bugs but there are XXX comments in the code that highlight known problems and potential areas for improvement. I've also had a chat with the bzr-stats guys (Hi Jelmer, John!) and am seeking ways to consolidate that code. cheers, jml _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
