As a starting point, here's a paper by some smart folks at Microsoft Research: http://research.microsoft.com/en-us/um/people/abegel/papers/codebook-icse2010.pdf More generally, there's the Mining Software Repositories conference: http://2012.msrconf.org/http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment11http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment11Wed, 12 Oct 2011 03:07:44 GMTDefine a nice model around this question, create a git hook which updates some ravendb docs (curl) on each commit and let indexing do the rest?http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment10http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment10Tue, 11 Oct 2011 23:31:53 GMTNice idea. Btw, I would be interested in how you handle code ownership in you company. Does every developer own a piece? Microsoft does it this way.http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment9http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment9Tue, 11 Oct 2011 19:19:11 GMTI can see it already: RavenVC, running on a RavenDB backend. A "second generation distributed version control system"! :)http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment8http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment8Tue, 11 Oct 2011 16:36:27 GMTThis can only mean one thing, Ayende is about to create his own DVCS xDhttp://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment7http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment7Tue, 11 Oct 2011 15:51:33 GMTWhat about automatic code reformatting that could be made by anyone but is not an indication of knowledge sharing?http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment6http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment6Tue, 11 Oct 2011 12:43:24 GMTActually the code need a small modification as it solves the task "to find files modified exclusively by specific user" but not "to find files modified exclusively by one user". But the general idea is the same: retrieve the list of current files by "list" command and then pass this list to "log" command which returns modifiers.http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment5http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment5Tue, 11 Oct 2011 11:53:18 GMTInteresting idea. I found this (http://stackoverflow.com/questions/6572728/svn-list-of-files-changed-exclusively-by-1-user) solution for SVN. I guess it is pretty simple to port it to Git.http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment4http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment4Tue, 11 Oct 2011 11:38:07 GMTAnother way to find troublesome code is to analyze which file(s) are being changed most often. This could indicate a violation of SRP, perhaps other things too. There are tools that do this already, but I can't remember any names right now.http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment3http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment3Tue, 11 Oct 2011 11:01:22 GMTScooletz, This assume that you are doing this check on a single branchhttp://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment2http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment2Tue, 11 Oct 2011 10:49:44 GMTWhat about forks which were not pulled back?http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment1http://ayende.com/107521/idle-musing-while-commuting-the-ownership-index#comment1Tue, 11 Oct 2011 10:47:59 GMT
