Junio C Hamano	13956670a7	Use 'merge-base --all' where applicable. It may get extra merge base on truly pathological commit histories, but is a lot easier to understand, explain, and prove correctness. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	64da9e604e	Add 'ours' merge strategy. This adds the coolest merge strategy ever, "ours". It can take arbitrary number of foreign heads and merge them into the current branch, with the resulting tree always taken from our branch head, hence its name. What this means is that you can declare that the current branch supersedes the development histories of other branches using this merge strategy.

Junio C Hamano	123ee3ca7b	Add --no-commit to git-merge/git-pull. With --no-commit flag, git-pull will perform the merge but pretends as if the merge needed a hand resolve even if automerge cleanly resolves, to give the user a chance to add further changes and edit the commit message.

Chris Shoemaker	50b8e355b6	Documentation changes to recursive option for git-diff-tree Update docs and usages regarding '-r' recursive option for git-diff-tree. Remove '-r' from common diff options, mention it only for git-diff-tree. Remove one extraneous use of '-r' with git-diff-files in get-merge.sh. Sync the synopsis and usage string for git-diff-tree.

Junio C Hamano	4f692b1978	Allow git-merge not to commit. Martin Langhoff wants to use git-merge from outside git-pull and wants to do further processing; for this, he wants git-merge no to commit even when it cleanly merges. I think other script writers would want something like that as well, so here it is. Instead of the "merge commit message" parameter (which usually is made for you by "git-pull" which calls this command), you pass an empty string to it. Then it will not update your HEAD -- you can do whatever you want with the resulting index file, which contains the merge results. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Fredrik Kuivinen	88f8f0a52b	[PATCH] Enable and fix support for base less merges. Let the merge strategies handle the base less case if they are able to do it. It also fixes git-resolve.sh to die if no common ancestors exists, instead of doing the wrong thing. Furthermore, it contains a small independent fix for git-merge.sh and a fix for a base less code path in gitMergeCommon.py. With this it's possible to use git merge -s recursive 'merge message' A B to do a base less merge of A and B. [jc: Thanks Fredrik for fixing the brown-paper-bag in git-merge. I fixed a small typo in git-merge-resolve fix; 'test' equality check is spelled with single equal sign -- C-style double equal sign is bashism.] Signed-off-by: Fredrik Kuivinen <freku045@student.liu.se> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	f9d72413bc	Handle really trivial case inside git-merge. Using Linus' --trivial option, this handles really trivial case inside git-merge itself, without using any strategy modules. A 'really trivial case' is: - we are merging one branch into the current branch; - there is only one merge base between the branches; - there is no file-level merge required.

Junio C Hamano	bf7960eb51	Use git-update-ref in scripts. This uses the git-update-ref command in scripts for safer updates. Also places where we used to read HEAD ref by using "cat" were fixed to use git-rev-parse. This will matter when we start using symbolic references. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	60fa056052	Fastpath the normal case by not checking that index matches HEAD. The merge strategy would check this itself and typically does it by using git-read-tree -m -u 3-way merge. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	deca7e8c59	Give default merge message after failed automerge. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	a935824036	Fix overzealous cleanliness check in git-merge Being able to try multiple strategies and automatically picking one that seems to give less conflicting result may or may not much sense in practice. At least that should not force normal use case to additionally require the working tree to be fully clean. As Linus shouted, local changes do not matter unless they interfere with the merge. This commit changes git-merge not to require a clean working tree. Only when we will iterate through more than one merge strategies, local changes are stashed away before trying the first merge, and restored before second and later merges are attempted. The index file must be in sync with HEAD in any case -- otherwise the merge result would contain changes since HEAD that was done locally and registered in the index. This check is already enforced by three-way read-tree existing merge strategies use, but is done here as a safeguard as well. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Fredrik Kuivinen	8cc01e5019	[PATCH] More descriptive messages for conflict cases in merges The merge strategies can give more descriptive error messages for conflict cases if they are given the actual branch names instead of the SHA1s.

Fredrik Kuivinen	e4cf17ce0d	[PATCH] Rename the 'fredrik' merge strategy to 'recursive'. Otherwise we would regret when Fredrik comes up with another merge algorithm with different pros-and-cons with the current one.

Junio C Hamano	f88ed172e7	Fix off-by-one error in git-merge 'git-merge -s' without a strategy name does not fail and does not give usage as it should. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	720d150c48	Add a new merge strategy by Fredrik Kuivinen. I really wanted to try this out, instead of asking for an adjustment to the 'git merge' driver and waiting. For now the new strategy is called 'fredrik' and not in the list of default strategies to be tried. The script wants Python 2.4 so this commit also adjusts Debian and RPM build procecure files.

Junio C Hamano	2276aa6c09	Use Daniel's read-tree in the merge strategy 'resolve'. And rename the one Linus kept calling stupid, 'stupid'. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	91063bbc6c	Multi-backend merge driver. The new command 'git merge' takes the current head and one or more remote heads, with the commit log message for the automated case. If the heads being merged are simple fast-forwards, it acts the same way as the current 'git resolve'. Otherwise, it tries different merge strategies and takes the result from the one that succeeded auto-merging, if there is any. If no merge strategy succeeds auto-merging, their results are evaluated for number of paths needed for hand resolving, and the one with the least number of such paths is left in the working tree. The user is asked to resolve them by hand and make a commit manually. The calling convention from the 'git merge' driver to merge strategy programs is very simple: - A strategy program is to be called 'git-merge-<strategy>'. - They take input of this form: <common1> <common2> ... '--' <head> <remote1> <remote2>... That is, one or more the common ancestors, double dash, the current head, and one or more remote heads being merged into the current branch. - Before a strategy program is called, the working tree is matched to the current <head>. - The strategy program exits with status code 0 when it successfully auto-merges the given heads. It should do update-cache for all the merged paths when it does so -- the index file will be used to record the merge result as a commit by the driver. - The strategy program exits with status code 1 when it leaves conflicts behind. It should do update-cache for all the merged paths that it successfully auto-merged, and leave the cache entry in the index file as the same as <head> for paths it could not auto-merge, and leave its best-effort result with conflict markers in the working tree when it does so. - The strategy program exists with status code other than 0 or 1 if it does not handle the given merge at all. As examples, this commit comes with merge strategies based on 'git resolve' and 'git octopus'. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
