If they want to commit to a different branch, they can b****y well check out that branch and merge to _that_. That is the way all the rest of git works and nobody whines that this is a restriction. Quite the opposite: that git-svn does not feel constrained to actually commit to the base of the checked-out branch is a complete nuisance. _Why_ would anybody want to dcommit to a Subversion branch not associated with the current branch? Just yesterday, I _again_ had git-svn dcommit to a nonsensical branch (this time, the commit was to branch instead of the trunk, while more often the catastrophes happen the other way round). And it is not like git-svn gives you a chance to override this bad decision: you have to rebase -i all of your commit messages from potential cherrypicks or whatever else and remove the git-svn taglines manually for every commit before git-svn will deign to dcommit to the same branch as before. Eric, this is not "flexibility". This is madness. If you think that it is essential to dcommit to a branch unrelated to the current HEAD, then create a sane command line interface for it that takes effect at the time of dcommit. But the current interface is just throwing dice as far as the user is concerned, since the addition of git-svn tags to commit messages happens behind his back, and any merge or cherrypick or rebase 5 revisions back might come to bite you. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
