I had a theory that we might be getting better at preventing regressions now than a year or so ago due to the expansion of things like AppDB and the test suite. It'd be nice to have some sort of data though.
Would it be reasonable to comb through the bugzilla database for all the bugs tagged regression and analyze them? I'm interested in:
- quantity and frequency of bugs tagged regression that were filed at
various dates since the release of 1.0. I'm not sure whether it's better to use the version number field in bugzilla as a proxy for "first version with regression" or to just guess that from the date. 2) how long regression bugs took to be fixed
Thanks, Scott Ritchie
It'd be better to use the SHA1SUM of the bad patch, which will give you the day the regression was added.
If the fix has the SHA1SUM listed in there as well, it's even easier for you.
