Using Git bisect to quickly locate and introduce the wrong version

Now there is a project, in the development of the day, by an engineer introduced a bug, take the system and not go, directly lock the database connection. The project uses the Java Platform for version management on SVN. I do not want a version of code review troubleshooting, think of the most violent binary version of the method, of course, in SVN to do means to a version checkout out, so big project, is also very time-consuming, at this time, Git-bisect is my only choice.

First, export the SVN repository as a git library:
$ git svn clone-s http://svn.xxx.com/svn/xxxxx
Then, start git bisect:
$ git bisect start
Mark the current version as error:
$ git bisect bad
Find the version of the previous day, do a tag (tag20090106), test for the correct, mark it:
$ git bisect good tag20090106
At this point git will tell you to choose an intermediate version, then start compiling, testing, if not, execute:
$ git bisect bad
Git will use the binary method to look forward to an intermediate version, start compiling, testing, if passed, execute:
$ git bisect good
Git will continue to locate revision until it finally navigates to a bug-introducing version, then analyze the reason, and then find the troublesome engineer Pk,pk finished back to the end of the execution:
$ git bisect reset
Git will return to the current head.
