2011-11-08merge: make usage of commit->util more extensibleLibravatar Junio C Hamano1-40/+23
The merge-recursive code uses the commit->util field directly to annotate the commit objects given from the command line, i.e. the remote heads to be merged, with a single string to be used to describe it in its trace messages and conflict markers. Correct this short-signtedness by redefining the field to be a pointer to a structure "struct merge_remote_desc" that later enhancements can add more information. Store the original objects we were told to merge in a field "obj" in this struct, so that we can recover the tag we were told to merge. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-10-12Teach merge the '[-e|--edit]' optionLibravatar Jay Soffian1-39/+70
Implemented internally instead of as "git merge --no-commit && git commit" so that "merge --edit" is otherwise consistent (hooks, etc) with "merge". Note: the edit message does not include the status information that one gets with "commit --status" and it is cleaned up after editing like one gets with "commit --cleanup=default". A later patch could add the status information if desired. Note: previously we were not calling stripspace() after running the prepare-commit-msg hook. Now we are, stripping comments and leading/trailing whitespace lines if --edit is given, otherwise only stripping leading/trailing whitespace lines if not given --edit.

2011-09-18Accept tags in HEAD or MERGE_HEADLibravatar Nguyễn Thái Ngọc Duy1-5/+2
HEAD and MERGE_HEAD (among other branch tips) should never hold a tag. That can only be caused by broken tools and is cumbersome to fix by an end user with: $ git update-ref HEAD $(git rev-parse HEAD^{commit}) which may look like a magic to a new person. Be easy, warn users (so broken tools can be fixed if they bother to report) and move on. Be robust, if the given SHA-1 cannot be resolved to a commit object, die (therefore return value is always valid).

2011-09-18merge: remove global variable head[]Libravatar Nguyễn Thái Ngọc Duy1-44/+53
Also kill head_invalid in favor of "head_commit == NULL". Local variable "head" in cmd_merge() is renamed to "head_sha1" to make sure I don't miss any access because this variable should not be used after head_commit is set (use head_commit->object.sha1 instead).

2011-09-18merge: use return value of resolve_ref() to determine if HEAD is invalidLibravatar Nguyễn Thái Ngọc Duy1-1/+1
resolve_ref() only updates "head" when it returns non NULL value (it may update "head" even when returning NULL, but not in all cases). Because "head" is not initialized before the call, is_null_sha1() is not enough. Check also resolve_ref() return value.

2011-09-15Allow git merge ":/<pattern>"Libravatar Junio C Hamano1-5/+14
It probably is not such a good idea to use ":/<pattern>" to specify which commit to merge, as ":/<pattern>" can often hit unexpected commits, but somebody tried it and got a nonsense error message: fatal: ':/Foo bar' does not point to a commit So here is a for-the-sake-of-consistency update that is fairly useless that allows users to carefully try not shooting in the foot.

2011-08-19want_color: automatically fallback to color.uiLibravatar Jeff King1-4/+0
All of the "do we want color" flags default to -1 to indicate that we don't have any color configured. This value is handled in one of two ways: 1. In porcelain, we check early on whether the value is still -1 after reading the config, and set it to the value of color.ui (which defaults to 0). 2. In plumbing, it stays untouched as -1, and want_color defaults it to off. This works fine, but means that every porcelain has to check and reassign its color flag. Now that want_color gives us a place to put this check in a single spot, we can do that, simplifying the calling code.

2011-08-18diff: refactor COLOR_DIFF from a flag into an intLibravatar Jeff King1-2/+0
This lets us store more than just a bit flag for whether we want color; we can also store whether we want automatic colors. This can be useful for making the automatic-color decision closer to the point of use. This mostly just involves replacing DIFF_OPT_* calls with manipulations of the flag. The biggest exception is that calls to DIFF_OPT_TST must check for "o->use_color > 0", which lets an "unknown" value (i.e., the default) stay at "no color". In the previous code, a value of "-1" was not propagated at all. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-05-26clean up calling conventions for pretty.c functionsLibravatar Jeff King1-1/+2
We have a pretty_print_context representing the parameters for a pretty-print session, but we did not use it uniformly. As a result, functions kept growing more and more arguments. Let's clean this up in a few ways: 1. All pretty-print pp_* functions now take a context. This lets us reduce the number of arguments to these functions, since we were just passing around the context values separately. 2. The context argument now has a cmit_fmt field, which was passed around separately. That's one less argument per function. 3. The context argument always comes first, which makes calling a little more uniform. This drops lines from some callers, and adds lines in a few places (because we need an extra line to set the context's fmt field). Overall, we don't save many lines, but the lines that are there are a lot simpler and more readable. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The merge-recursive strategy already handles root commits; it cherry-picks the difference between the empty tree and the root commit's tree. However, for external strategies, we dereference NULL and segfault while building the argument list. Instead, let's handle this by passing the empty tree sha1 to the merge script.

2011-03-25merge: merge unborn index before setting refLibravatar Jeff King1-1/+1
When we merge into an unborn branch, there are basically two steps: 1. Write the sha1 of the new commit into the ref pointed to by HEAD. 2. Update the index with the new content, and check it out to the working tree. We currently do them in this order. However, (2) is the step that is much more likely to fail, since it can be blocked by things like untracked working tree files. When it does, the merge fails and we are left with an empty index but an updated HEAD. This patch switches the order, so that a failure in updating the index leaves us unchanged. Of course, a failure in updating the ref now leaves us with an updated index and mis-matched HEAD. That is arguably not much better, but it is probably less likely to actually happen.

2011-02-21Introduce CHERRY_PICK_HEADLibravatar Jay Soffian1-0/+7
When a cherry-pick conflicts git advises: $ git commit -c <original commit id> to preserve the original commit message and authorship. Instead, let's record the original commit id in CHERRY_PICK_HEAD and advise: $ git commit -c CHERRY_PICK_HEAD A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part. Note that we record CHERRY_PICK_HEAD even in the case where there are no conflicts so that we may use it to communicate authorship to commit; this will then allow us to remove set_author_ident_env from revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit is used, as presumably the user intends to further edit the commit and possibly even cherry-pick additional commits on top.
