That's right. In practice I bisect the date instead; that way I can issue the same command in all my svn source directories from sf.net and lbl.gov. For example:
svn update -r "{2014-03-08 18:00}”
You can do that with git as well but it looks more geeky: git checkout `git rev-list -n 1 --before="2014-03-08 18:00” master` although you could easily put that in a tiny script called checkout-date and then issue “git checkout-date”. In any case, git bisect is easy to run in the simple case where you know HEAD is broken but 3c303a24 is good: % git bisect start HEAD 3c303a24 — This will checkout some version half-way through. You test and you find it’s broken: % git bisect bad If on the contrary, you find it works fine: % git bisect good Either of those commands will again checkout some version half-way through. Then you continue until git tells you the bisection is done.
