| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the command line arguments, after giving zero or more revs, you can feed a line "--" and then feed pathspecs one at a time.

| | | | | | | | | | | | | | | | | | This is necessary because we will later allow pathspecs to be fed from the standard input, and pathspecs taken from the command line (and converted via get_pathspec() already) in revs->prune_data too early gets in the way when we want to append from the standard input.

| * Teach --stdin option to "log" familyJunio C Hamano2009-11-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the logic to read revs from standard input that rev-list knows about from it to revision machinery, so that all the users of setup_revisions() can feed the list of revs from the standard input when "--stdin" is used on the command line. Allow some users of the revision machinery that want different semantics from the "--stdin" option to disable it by setting an option in the rev_info structure. This also cleans up the kludge made to bundle.c via cut and paste. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | Add '--bisect' revision machinery argumentLinus Torvalds2009-10-28
|/ | | | | | | | | | | | | | | | | | | | | | I personally use "git bisect visualize" all the time when I bisect, but it turns out that that is not a very flexible model. Sometimes I want to do bisection based on all commits (no pathname limiting), but then visualize the current bisection tree with just a few pathnames because I _suspect_ those pathnames are involved in the problem but am not totally sure about them. And at other times, I want to use other revision parsing logic, none of which is available with "git bisect visualize". So this adds "--bisect" as a revision parsing argument, and as a result it just works with all the normal logging tools. So now I can just do gitk --bisect --simplify-by-decoration filename-here etc. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* improve reflog date/number heuristicJeff King2009-09-29
| | | | | | | | | | | | | | | | | | | | | | | When we show a reflog, we have two ways of naming the entry: by sequence number (e.g., HEAD@{0}) or by date (e.g., HEAD@{10 minutes ago}). There is no explicit option to set one or the other, but we guess based on whether or not the user has provided us with a date format, showing them the date version if they have done so, and the sequence number otherwise. This usually made sense if the use did something like "git log -g --date=relative". However, it didn't make much sense if the user set the date format using the log.date config variable; in that case, all of their reflogs would end up as dates. This patch records the source of the date format and only triggers the date-based view if --date= was given on the command line. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Shawn O.

| * graph API: fix bug in graph_is_interesting()Adam Simpkins2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, graph_is_interesting() did not behave quite the same way as the code in get_revision(). As a result, it would sometimes think commits were uninteresting, even though get_revision() would return them. This resulted in incorrect lines in the graph output. This change creates a get_commit_action() function, which graph_is_interesting() and simplify_commit() both now use to determine if a commit will be shown. It is identical to the old simplify_commit() behavior, except that it never calls rewrite_parents(). This problem was reported by Santi BĂ©jar. The following command would exhibit the problem before, but now works correctly: git log --graph --simplify-by-decoration --oneline v1.6.3.3 Previously git graph did not display the output for this command correctly between f29ac4f and 66996ec, among other places.

* | git-log: allow --decorate[=short|full]Lars Hjemli2009-08-18
|/ | | | | | | | | | | | | | | Commit de435ac0 changed the behavior of --decorate from printing the full ref (e.g., "refs/heads/master") to a shorter, more human-readable version (e.g., just "master"). While this is nice for human readers, external tools using the output from "git log" may prefer the full version. This patch introduces an extension to --decorate to allow the caller to specify either the short or the full versions.

* Make 'git show' more usefulLinus Torvalds2009-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason, I ended up doing git show HEAD~5.. as an odd way of asking for a log. I realize I should just have used "git log", but at the same time it does make perfect conceptual sense. After all, you _could_ have done git show HEAD HEAD~1 HEAD~2 HEAD~3 HEAD~4 and saying "git show HEAD~5.." is pretty natural. It's not like "git show" only ever showed a single commit (or other object) before either! So conceptually, giving a commit range is a very sensible operation, even though you'd traditionally have used "git log" for that. However, doing that currently results in an error fatal: object ranges do not make sense when not walking revisions which admittedly _also_ makes perfect sense - from an internal git implementation standpoint in 'revision.c'. However, I think that asking to show a range makes sense to a user, while saying "object ranges no not make sense when not walking revisions" only makes sense to a git developer. So on the whole, of the two different "makes perfect sense" behaviors, I think I originally picked the wrong one. And quite frankly, I don't really see anybody actually _depending_ on that error case. So why not change it? So rather than error out, just turn that non-walking error case into a "silently turn on walking" instead.

* git log: add '--merges' flag to match '--no-merges'Linus Torvalds2009-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I do various statistics on git, and one of the things I look at is merges, because they are often interesting events to count ("how many merges vs how much 'real development'" kind of statistics). And you can do it with some fairly straightforward scripting, ie git rev-list --parents HEAD | grep ' .* ' | git diff-tree --always -s --pretty=oneline --stdin | less -S will do it. But I finally got irritated with the fact that we can skip merges with '--no-merges', but we can't do the trivial reverse operation. So this just adds a '--merges' flag that _only_ shows merges. Now you can do the above with just a git log --merges --pretty=oneline which is a lot simpler. It also means that we automatically get a lot of statistics for free, eg git shortlog -ns --merges does exactly what you'd want it to do.

* Clean up and simplify rev_compare_tree()Linus Torvalds2009-06-03
| | | | | | | | | | | | | | | | | | This simplifies the logic of rev_compare_tree() by removing a special case. It does so by turning the special case of finding a diff to be "all new files" into a more generic case of "all new" vs "all removed" vs "mixed changes", so now the code is actually more powerful and more generic, and the added symmetry actually makes it simpler too. This makes no changes to any existing behavior, but apart from the simplification it does make it possible to some day care about whether all changes were just deletions if we want to. Which we may well want to for merge handling. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Now, I didn't do that latter optimization, because it would require some more coding, but especially looking at "builtin-pack-objects.c", we really don't even want the whole pathname, we really would be better off with the list of path components. Why? We use that name for two things: - add_preferred_base_object(), which actually _wants_ to traverse the path, and now does it by looking for '/' characters! - for 'name_hash()', which only cares about the last 16 characters of a name, so again, generating the full name seems to be just unnecessary work. Anyway, so I didn't look any closer at those things, but it did convince me that the "show_object()" calling convention was crazy, and we're actually better off doing _less_ in list-objects.c, and giving people access to the internal data structures so that they can decide whether they want to generate a path-name or not. This patch does that, and then for people who did use the name (even if they might do something more clever in the future), it just does the straightforward "name = path_name(path, component); .. free(name);" thing.

| * process_{tree,blob}: show objects without bufferingLinus Torvalds2009-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here's a less trivial thing, and slightly more dubious one. I was looking at that "struct object_array objects", and wondering why we do that. I have honestly totally forgotten. Why not just call the "show()" function as we encounter the objects? Rather than add the objects to the object_array, and then at the very end going through the array and doing a 'show' on all, just do things more incrementally. Now, there are possible downsides to this: - the "buffer using object_array" _can_ in theory result in at least better I-cache usage (two tight loops rather than one more spread out one). I don't think this is a real issue, but in theory.. - this _does_ change the order of the objects printed. Instead of doing a "process_tree(revs, commit->tree, &objects, NULL, "");" in the loop over the commits (which puts all the root trees _first_ in the object list, this patch just adds them to the list of pending objects, and then we'll traverse them in that order (and thus show each root tree object together with the objects we discover under it) I _think_ the new ordering actually makes more sense, but the object ordering is actually a subtle thing when it comes to packing efficiency, so any change in order is going to have implications for packing. Good or bad, I dunno. - There may be some reason why we did it that odd way with the object array, that I have simply forgotten. Anyway, now that we don't buffer up the objects before showing them that may actually result in lower memory usage during that whole traverse_commit_list() phase. This is seriously not very deeply tested. It makes sense to me, it seems to pass all the tests, it looks ok, but... Does anybody remember why we did that "object_array" thing? It used to be an "object_list" a long long time ago, but got changed into the array due to better memory usage patterns (those linked lists of obejcts are horrible from a memory allocation standpoint). But I wonder why we didn't do this back then. Maybe there's a reason for it. Or maybe there _used_ to be a reason, and no longer is. Signed-off-by: Junio C Hamano <gitster@pobox.com>

This resulted in an early end of "git log" output or a pack that lacks older commits from "git pack-objects", without any error indication in the exit status from these commands, even though the underlying parse_commit() issues an error message to the end user. Note that the codepath in add_parents_list() that paints parents of an UNINTERESTING commit UNINTERESTING silently ignores the error when parse_commit() fails; this is deliberate and in line with aeeae1b (revision traversal: allow UNINTERESTING objects to be missing, 2009-01-27).

It also makes the parameter passing much simpler - the callers doesn't really look at trees anywhere else, and it's really the function that should look at the low-level details.

We can abuse the '->util' field in the commit to keep track of that as we walk the commit lists, and get a reasonably useful view into which branch or tag first reaches that commit. Of course, if the commit is reachable through multiple sources (which is common), our particular choice of "first" reachable is entirely random and depends on the particular path we happened to follow.

(Without --reverse, it correctly lists M.) This is caused by the machinery driving --reverse: it first grabs all commits through the normal routines, then runs them through the same routines again, effectively simplifying them twice. Fix this by moving the --reverse one level up, into get_revision(). This way we can cleanly grab all commits via the normal calls, then just pop them off the list one by one without interfering with get_revision_internal().

This had a few problems: * When looking for fixed strings (e.g. "git log -F --author=x --grep=y"), the regexp internally used "^author .*x" would never match anything; * To match at the end (e.g. "git log --author='google.com>$'"), the generated regexp has to also match the trailing timestamp part the commit header lines have. Also, in order to determine if the '$' at the end means "match at the end of the line" or just a literal dollar sign (probably backslash-quoted), we would need to parse the regexp ourselves. An earlier alternative tried to make sure that a line matches "^author " (to limit by field name) and the user supplied pattern at the same time. While it solved the -F problem by introducing a special override for matching the "^author ", it did not solve the trailing timestamp nor tail match problem. It also would have matched every commit if --author=author was asked for, not because the author's email part had this string, but because every commit header line that talks about the author begins with that field name, regardleses of who wrote it. Instead of piling more hacks on top of hacks, this rethinks the grep machinery that is used to look for strings in the commit header, and makes sure that (1) field name matches literally at the beginning of the line, followed by a SP, and (2) the user supplied pattern is matched against the remainder of the line, excluding the trailing timestamp data.
