* Add '...' operator for revisionsRene Scharfe2006-07-01
| | | | | | | | | | | | | 'A...B' is a shortcut for 'A B --not $(git-merge-base --all A B)'. This XOR-like operation is called symmetric difference in set theory. The symbol '...' has been chosen because it's rather similar to the existing '..' operator and the somewhat more natural caret ('^') is already taken.

* Add get_merge_bases_clean()Rene Scharfe2006-07-01
| | | | | | | | | | | | | | | Add get_merge_bases_clean(), a wrapper for get_merge_bases() that cleans up after doing its work and make get_merge_bases() NOT clean up. Single-shot programs like git-merge-base can use the dirty and fast version. Also move the object flags used in get_merge_bases() out of the range defined in revision.h. This fixes the "66ae0c77...ced9456a 89719209...262a6ef7" test of the ... operator which is introduced with the next patch.

| * git-repack: Be careful when updating the same pack as an existing one.Junio C Hamano2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a clone, packfiles are read-only by default and "mv" to replace the pack with a new one goes interactive, asking if the user wants to replace it. If one is successfully moved and the other is not, the pack and its idx would become out-of-sync and corrupts the repository. Recovering is straightforward -- it is just the matter of finding the remaining .tmp-pack-* and make sure they are both moved -- but we should be extra careful not to do something so alarming to the users.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Slower connections can make git-svn look as if it's doing nothing for a long time; leaving the user wondering if we're actually doing anything.

This relies on the SVN::* libraries to work. We can't reliably parse path info from the svn command-line client without relying on XML, so it's better just to have the SVN::* libs installed. This also removes oldvalue verification when calling update-ref In SVN, branches can be deleted, and then recreated under the same path as the original one with different ancestry information, causing parent information to be mismatched / misordered. Also force the current ref, if existing, to be a parent, regardless of whether or not it was specified. --no-metadata: This gets rid of the git-svn-id: lines at the end of every commit. With this, you lose the ability to use the rebuild command. If you ever lose your .git/svn/git-svn/.rev_db file, you won't be able to fetch again, either. This is fine for one-shot imports. Also fix some issues with multi-fetch --follow-parent that were exposed while testing this. Additionally, repack checking is simplified greatly. git-svn log will not work on repositories using this, either.

We ensure that tree joins (--branch and --branch-all-refs options) during commit time only add SVN parents that occurred before the commit we're importing Also fixed branch detection via merge messages, this manner of merge detection (a la git-svnimport) is really all fuzzy, but at least it actually works now :) Add some new tests to go along with these fixes, too.

I'm probably overflushing my file handles, but that's the safest thing to do... * BDB kept segfaulting on me during tests, so svnadmin will use FSFS whenever we can. * If somebody used an expanded CVS $Id$ line inside a file, then propsetting it to use svn:keywords will cause the original CVS $Id$ to be retained when asked for the original file. As far as I can see, this is a server-side issue. We won't care in the test anymore, as long as it's not expanded by SVN, a static CVS $Id$ line is fine. While we're at making ourselves more compatible, avoid grep along with the -q flag, which is GNU-specific.

The topic is then abandoned or forked off again from that point at the mainline. The barebone porcelainish that comes with core git tools does not officially support such operation, but you can fake it by using "git pull --no-merge" when such a topic branch is not a strict superset of the mainline, like this: git checkout mainline git pull --no-commit . that-topic-branch : fix conflicts if any rm -f .git/MERGE_HEAD git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged This however does not work when the topic branch is a fast forward of the mainline, because normal "git pull" will never create a merge commit in such a case, and there is nothing special --no-commit could do to begin with. This patch introduces a new option, --squash, to support such a workflow officially in both fast-forward case and true merge case. The user-level operation would be the same in both cases: git checkout mainline git pull --squash . that-topic-branch : fix conflicts if any -- naturally, there would be : no conflict if fast forward. git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged When the current branch is already up-to-date with respect to the other branch, there truly is nothing to do, so the new option does not have any effect.

This is particularly bad when importing history from another SCM (tailor 0.9.23 uses git-commit). In the best cases all lines are stripped and the commit fails with a confusing "empty log message" error, but in many cases the commit is done, with loss of information. Note that it is quite peculiar to just have "#" handled as a leading comment char here. One commonly meet CVS: or CG: or STG: as prefixes, and using GIT: would be more robust as well as consistent with other commit tools. However, that would break any tool relying on the # (if any).
