答复: Can SVN pull request same as GIT?

In the past, we used another way to implement functions similar to pull requests:



We make a pre-commit code review like this ( we named it as Force Review):

1.Before developer commit code, user can use ForceReview command to create an online code review. ForceReview command is a tool to upload patches and start review .

   It can work at working copy, command like this : ForceReview @ReviewerA @ReviewerB -m ${Subject}



2.Reviewer review the code , and complete it. In fact , user will change his code and iterative pre-commit review.



3.When code review completed, developer can use code review ID to commit his code. One ID can only commit his code one time.



SVN use a pre-commit to make sure the code has code reviewed:

1.First we will define which code need to code review. We use regular expression to match those code.

2.Then pre-commit script will get the code review ID in log message. And to determine if the code is allowed to be commit.

Yes, that's exactly the point. The easiest way to implement a "pull

request" workflow in Subversion is to use multiple branches within

a single repository.



At the data model level, pull requests are feature branches. The

differences are in the surrounding social patterns and in tooling built

around the "pull request - review - merge" workflow. Such tooling could

be implemented on top of Subversion 1.1.0 (sic), and has been.

Using multiple repositories and porting commits between them amounts to

implementing a DVCS (such as git-svn) on top of Subversion. However, as

several people already pointed out, there's no need to be distributed in

order to support pull requests. One only needs to be able to pass

patches around; branches achieve that.



Cheers,



Daniel
