Bad graft data is noticed in several places in read_graft_line(), and in each case we go back to the first site of detection. It in general is a better style to have an exception handling out of line from the main codepath and make error codepath jump forward.

2010-04-01make commit_tree a library functionLibravatar Jeff King1-0/+55
Until now, this has been part of the commit-tree builtin. However, it is already used by other builtins (like commit, merge, and notes), and it would be useful to access it from library code. The check_valid helper has to come along, too, but is given a more library-ish name of "assert_sha1_type". Otherwise, the code is unchanged. There are still a few rough edges for a library function, like printing the utf8 warning to stderr, but we can address those if and when they come up as inappropriate.

This change is being offered as a refactoring to make later commits in the smart HTTP series easier. By changing the enabled capabilities to be formatted in a strbuf it is easier to add a new capability to the set of supported capabilities. By formatting the want portion of the request into a strbuf and writing it as a whole block we can later decide to hold onto the req_buf (instead of releasing it) to recycle in stateless communications.

2009-10-19Introduce commit notesLibravatar Johannes Schindelin1-0/+1
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. This patch has been improved by the following contributions: - Thomas Rast: fix core.notesRef documentation - Tor Arne Vestbø: fix printing of multi-line notes - Alex Riesen: Using char array instead of char pointer costs less BSS - Johan Herland: Plug leak when msg is good, but msglen or type causes return Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Tor Arne Vestbø <tavestbo@trolltech.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com> get_commit_notes(): Plug memory leak when 'if' triggers, but not because of read_sha1_file() failure

In 2d14d65 (Use a clearer style to issue commands to remote helpers, 2009-09-03) I happened to notice two changes like this: - write_in_full(helper->in, "list\n", 5); + + strbuf_addstr(&buf, "list\n"); + write_in_full(helper->in, buf.buf, buf.len); + strbuf_reset(&buf); IMHO, it would be better to define a new function, static inline ssize_t write_str_in_full(int fd, const char *str) { return write_in_full(fd, str, strlen(str)); } and then use it like this: - strbuf_addstr(&buf, "list\n"); - write_in_full(helper->in, buf.buf, buf.len); - strbuf_reset(&buf); + write_str_in_full(helper->in, "list\n"); Thus not requiring the added allocation, and still avoiding the maintenance risk of literal string lengths. These days, compilers are good enough that strlen("literal") imposes no run-time cost.

2009-07-24git repack: keep commits hidden by a graftLibravatar Johannes Schindelin1-1/+5
When you have grafts that pretend that a given commit has different parents than the ones recorded in the commit object, it is dangerous to let 'git repack' remove those hidden parents, as you can easily remove the graft and end up with a broken repository. So let's play it safe and keep those parent objects and everything that is reachable by them, in addition to the grafted parents. As this behavior can only be triggered by git pack-objects, and as that command handles duplicate parents gracefully, we do not bother to cull duplicated parents that may result by using both true and grafted parents.

2009-05-17commit: add function to unparse a commit and its parentsLibravatar Christian Couder1-0/+20
This patch adds the "unparse_commit" function that returns a commit into an unparsed state by freeing its data and resetting its fields to 0. Its parents are recursively unparsed too, because they might have been changed. But its tree is not unparsed as it should not have been modifed. Note that as the "flags" and "used" fields may be used even if the object is not parsed, we have to reset them anyway.

2008-07-23sort_in_topological_order(): avoid setting a commit flagLibravatar Johannes Schindelin1-7/+6
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.

2008-07-14reduce_heads(): protect from duplicate inputLibravatar Junio C Hamano1-2/+9

2008-06-30Introduce reduce_heads()Libravatar Junio C Hamano1-0/+45
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.

2008-06-30Introduce get_merge_bases_many()Libravatar Junio C Hamano1-18/+38
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.

2008-01-20parse_commit_buffer: tighten checks while parsingLibravatar Martin Koegler1-7/+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).

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.

For that purpose, the ->buf is always initialized with a char * buf living in the strbuf module. 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.
