| * Introduce commit notesJohannes Schindelin2008-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects.

* sort_in_topological_order(): avoid setting a commit flagJohannes Schindelin2008-07-23
| | | | | | | | | | | | | | | | | | | | | | We used to set the TOPOSORT flag of commits during the topological sorting, but we can just as well use the member "indegree" for it: indegree is now incremented by 1 in the cases where the commit used to have the TOPOSORT flag. This is the same behavior as before, since indegree could not be non-zero when TOPOSORT was unset. Incidentally, this fixes the bug in show-branch where the 8th column was not shown: show-branch sorts the commits in topological order, assuming that all the commit flags are available for show-branch's private matters. But this was not true: TOPOSORT was identical to the flag corresponding to the 8th ref. So the flags for the 8th column were unset by the topological sorting.

* reduce_heads(): protect from duplicate inputJunio C Hamano2008-07-14
| | | | | | | | | | Because we do not try computing merge base with itself for obvious reasons, the code was not prepared for an arguably insane case of the caller feeding the same commit twice to it.

* reduce_heads(): thinkofixSverre Hvammen Johansen2008-07-13
| | | | | | | | | | | | When comparing two commit objects for equality, it is sufficient to compare their in-core pointers because the object layer guarantees the uniqueness. However, comparing pointers to two "struct commit_list" instances that point at the same commit does not make any sense. Spotted by Sverre Hvammen Johansen who wrote an additional test to expose the problem, fixed by Miklos Vajna. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Introduce reduce_heads()Junio C Hamano2008-06-30
| | | | | | | | | | | | | | The new function reduce_heads() is given a list of commits, and removes ones that can be reached from other commits in the list. It is useful for reducing the commits randomly thrown at the git-merge command and remove redundant commits that the user shouldn't have given to it. The implementation uses the get_merge_bases_many() introduced in the previous commit. If the merge base between one commit taken from the list and the remaining commits is the commit itself, that means the commit is reachable from some of the other commits.

* Introduce get_merge_bases_many()Junio C Hamano2008-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a new function get_merge_bases_many() which is a natural extension of two commit merge base computation. It is given one commit (one) and a set of other commits (twos), and computes the merge base of one and a merge across other commits. This is mostly useful to figure out the common ancestor when iterating over heads during an octopus merge. When making an octopus between commits A, B, C and D, we first merge tree of A and B, and then try to merge C with it. If we were making pairwise merge, we would be recording the tree resulting from the merge between A and B as a commit, say M, and then the next round we will be computing the merge base between M and C. o---C...* / . o---B...M / . o---o---A But during an octopus merge, we actually do not create a commit M. In order to figure out that the common ancestor to use for this merge, instead of computing the merge base between C and M, we can call merge_bases_many() with one set to C and twos containing A and B.

* parse_commit_buffer: tighten checks while parsingMartin Koegler2008-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | This tightens the parsing of a commit object in a couple of ways. - The "tree " header must end with a LF (earlier we did not check this condition). - Make sure parsing of timestamp on the "committer " header does not go beyond the buffer, even when (1) the "author " header does not end with a LF (this means that the commit object is malformed and lacks the committer information) or (2) the "committer " header does not have ">" that is the end of the e-mail address, or (3) the "committer " header does not end with a LF. We however still keep the existing behaviour to return a parsed commit object even when non-structural headers such as committer and author are malformed, so that tools that need to look at commits to clean up a history with such broken commits can still get at the structural data (i.e. the parents chain and the tree object).

| * clear_commit_marks(): avoid deep recursionJohannes Schindelin2007-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this patch, clear_commit_marks() recursed for each parent. This could be potentially very expensive in terms of stack space. Probably the only reason that this did not lead to problems is the fact that we typically call clear_commit_marks() after marking a relatively small set of commits. Use (sort of) a tail recursion instead: first recurse on the parents other than the first one, and then continue the loop with the first parent. Noticed by Shawn Pearce.

It is made a char * so that we can sloppily accept things that perform: sb->buf[0] = '\0', and because you can't pass "" as an initializer for ->buf without making gcc unhappy for very good reasons. strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf anymore. as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying ->buf isn't an option anymore, if ->buf is going to escape from the scope, and eventually be free'd. API changes: * strbuf_setlen now always works, so just make strbuf_reset a convenience macro. * strbuf_detatch takes a size_t* optional argument (meaning it can be NULL) to copy the buffer's len, as it was needed for this refactor to make the code more readable, and working like the callers.

Currently, --pretty=oneline and --pretty=email (hence format-patch) take and use only the first line of the commit log message. This changes them to: - Take the first paragraph, where the definition of the first paragraph is "skip all blank lines from the beginning, and then grab everything up to the next empty line". - Replace all line breaks with a whitespace. This change would not affect a well-behaved commit message that adheres to the convention of "single line summary, a blank line, and then body of message", as its first paragraph always consists of a single line. Commit messages from different culture, such as the ones imported from CVS/SVN, can however get chomped with the existing behaviour at the first linebreak in the middle of sentence right now, which would become much easier to see with this change. The Subject: and --pretty=oneline output would become very long and unsightly for non-conforming commits, but their messages are already ugly anyway, and thischange at least avoids the loss of information.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally we had 16kB limit when formatting log messages for output, because it was easier to arrange for the caller to have a reasonably big buffer and pass it down without ever worrying about reallocating. This changes the calling convention of pretty_print_commit() to lift this limit. Instead of the buffer and remaining length, it now takes a pointer to the pointer that points at the allocated buffer, and another pointer to the location that stores the allocated length, and reallocates the buffer as necessary. To support the user format, the error return of interpolate() needed to be changed. It used to return a bool telling "Ok the result fits", or "Sorry, I had to truncate it". Now it returns 0 on success, and returns the size of the buffer it wants in order to fit the whole result. Signed-off-by: Junio C Hamano <gitster@pobox.com>
