2006-04-17rev-list --boundary: show boundary commits even when limited otherwise.Junio C Hamano
The boundary commits are shown for UI like gitk to draw them as soon as topo-order sorting allows, and should not be omitted by get_revision() filtering logic. As long as their immediate child commits are shown, we should not filter them out. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-11blame and friends: adjust to multiple pathspec change.Junio C Hamano
This makes things that include revision.h build again. Blame is also built, but I am not sure how well it works (or how well it worked to begin with) -- it was relying on tree-diff to be using whatever pathspec was used the last time, which smells a bit suspicious.

2006-04-09Make "--parents" logs also be incrementalLinus Torvalds
The parent rewriting feature caused us to create the whole history in one go, and then simplify it later, because of how rewrite_parents() had been written. However, with a little tweaking, it's perfectly possible to do even that one incrementally. Right now, this doesn't really much matter, because every user of "--parents" will probably generally _also_ use "--topo-order", which will cause the old non-incremental behaviour anyway. However, I'm hopeful that we could make even the topological sort incremental, or at least _partially_ so (for example, make it incremental up to the first merge). In the meantime, this at least moves things in the right direction, and removes a strange special case.

2006-04-01Move "--parent" parsing into generic revision.c library codeLinus Torvalds
Not only do we do it in both rev-list.c and git.c, the revision walking code will soon want to know whether we should rewrite parenthood information or not. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-03-29rev-list --boundaryJunio C Hamano
With the new --boundary flag, the output from rev-list includes the UNINTERESING commits at the boundary, which are usually not shown. Their object names are prefixed with '-'. For example, with this graph: C side / A---B---D master You would get something like this: $ git rev-list --boundary --header --parents side..master D B tree D^{tree} parent B ... log message for commit D here ... \0-B A tree B^{tree} parent A ... log message for commit B here ... \0 Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-03-11rev-lib: Make it easy to do rename tracking (take 2)Fredrik Kuivinen
prune_fn in the rev_info structure is called in place of try_to_simplify_commit. This makes it possible to do rename tracking with a custom try_to_simplify_commit-like function. This commit also introduces init_revisions which initialises the rev_info structure with default values.

2006-03-01git-log (internal): more options.Junio C Hamano
This ports the following options from rev-list based git-log implementation: * -<n>, -n<n>, and -n <n>. I am still wondering if we want this natively supported by setup_revisions(), which already takes --max-count. We may want to move them in the next round. Also I am not sure if we can get away with not setting revs->limited when we set max-count. The latest rev-list.c and revision.c in this series do not, so I left them as they are. * --pretty and --pretty=<fmt>. * --abbrev=<n> and --no-abbrev. The previous commit already handles time-based limiters (--since, --until and friends). The remaining things that rev-list based git-log happens to do are not useful in a pure log-viewing purposes, and not ported: * --bisect (obviously). * --header. I am actually in favor of doing the NUL terminated record format, but rev-list based one always passed --pretty, which defeated this option. Maybe next round. * --parents. I do not think of a reason a log viewer wants this. The flag is primarily for feeding squashed history via pipe to downstream tools. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-03-01Rip out merge-order and make "git log <paths>..." work again.Linus Torvalds
Well, assuming breaking --merge-order is fine, here's a patch (on top of the other ones) that makes git log <filename> actually work, as far as I can tell. I didn't add the logic for --before/--after flags, but that should be pretty trivial, and is independent of this anyway. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-28git-rev-list libification: rev-list walkingLinus Torvalds
This actually moves the "meat" of the revision walking from rev-list.c to the new library code in revision.h. It introduces the new functions void prepare_revision_walk(struct rev_info *revs); struct commit *get_revision(struct rev_info *revs); to prepare and then walk the revisions that we have.

2006-02-27Splitting rev-list into revisions lib, end of beginning.Linus Torvalds
This makes the rewrite easier to validate in that revision flag parsing and warlking part are now all in rev_info structure. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-26First cut at libifying revlist generationLinus Torvalds
This really just splits things up partially, and creates the interface to set things up by parsing the command line. No real code changes so far, although the parsing of filenames is a bit stricter. In particular, if there is a "--", then we do not accept any filenames before it, and if there isn't any "--", then we check that _all_ paths listed are valid, not just the first one. The new argument parsing automatically also gives us "--default" and "--not" handling as in git-rev-parse.

2005-04-21Include <limits.h> in commit.c for ULONG_MAX. Remove old "revision.h".Linus Torvalds
The old revision.h helper header isn't used any more, but I never noticed it until I started grepping for ULONG_MAX users.
2005-04-17Make the revision tracking track the object types too.Linus Torvalds
This allows fsck to verify not just that an object exists, but also that it has the type it was expected to have.
2005-04-17Make "parse_commit" return the "struct revision" for the commit.Linus Torvalds
Also, make it a fatal error to pass in a non-commit object. The callers never checked, so better check here. This simplifies merge-base further. It's now so trivial that it's almost ridiculous.
2005-04-17Make "revision.h" slightly better to use.Linus Torvalds
- mark_reachable() can be more generic, marking the reachable revisions with an arbitrary mask. - date parsing will parse to a date of 0 rather than ULONG_MAX for the bad old case, sorting the dates correctly.
2005-04-17Move "parse_commit()" into common revision.h file.Linus Torvalds
This also drops the old-style date parsing. We just don't care enough, since we dropped that format pretty early. Yes, this could do with some cleanup, and a common library file. Some day.
2005-04-14Use common "revision.h" header for both fsck and rev-tree.Linus Torvalds
It's really a very generic thing: the notion of one sha1 revision referring to another one. "fsck" uses it for all nodes, and "rev-tree" only tracks commit-node relationships, but the code was already the same - now we just make that explicit by moving it to a common header file.
