| * Provide git_config with a callback-data parameterJohannes Schindelin2008-05-14
| | | | | | | | | | | | | | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add a new option --no-binary to git-format-patch so that no binary changes are included in the generated patches, only notices that those files changed. This generate patches that cannot be applied, but still is useful for generating mails for code review purposes.

* log: teach "terminator" vs "separator" mode to "--pretty=format"Junio C Hamano2008-04-10
| | | | | | | | | | | | | | | | | | | | | This attached patch introduces a single bit "use_terminator" in "struct rev_info", which is normally false (i.e. most formats use separator semantics) but by flipping it to true, you can ask for terminator semantics just like oneline format does. The function get_commit_format(), which is what parses "--pretty=" option, now takes a pointer to "struct rev_info" and updates its commit_format and use_terminator fields. It used to return the value of type "enum cmit_fmt", but all the callers assigned it to rev->commit_format. There are only two cases the code turns use_terminator on. Obviously, the traditional oneline format (--pretty=oneline) is one of them, and the new case is --pretty=tformat:... that acts like --pretty=format:... but flips the bit on. With this, "--pretty=tformat:%H %s" acts like --pretty=oneline. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | log/show/whatchanged: introduce format.pretty configurationDenis Cheng2008-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running log/show/whatchanged from the command line, the user may want to use a preferred format without having to pass --pretty=<fmt> option every time from the command line. This teaches these three commands to honor a new configuration variable, format.pretty. The --pretty option given from the command line will override the configured format. The earlier patch fixed the in-tree callers that run these commands for purposes other than showing the output directly to the end user (the only other in-tree caller is "git bisect visualize", whose output directly goes to the end user and should be affected by this patch). Similar fixes will be needed for end-user scripts that parse the output from these commands and expect them to be in the default pretty format.

This makes all cover letter include shortlogs, and all cover letters for series with a single boundary commit include diffstats (if there are multiple boundary commits it's unclear what would be meaningful as a diffstat). Note that the single boundary test is empirical, not theoretical; even a -2 limiting condition will give a diffstat if there's only one boundary commit in this particular case.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An earlier fix to the said commit was incomplete; it mixed up the meaning of the flag parameter passed to the internal fmt_ident() function, so this corrects it. git_author_info() and git_committer_info() can be told to issue a warning when no usable user information is found, and optionally can be told to error out. Operations that actually use the information to record a new commit or a tag will still error out, but the caller to leave reflog record will just silently use bogus user information. Not warning on misconfigured user information while writing a reflog entry is somewhat debatable, but it is probably nicer to the users to silently let it pass, because the only information you are losing is who checked out the branch. * git_author_info() and git_committer_info() used to take 1 (positive int) to error out with a warning on misconfiguration; this is now signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME. * These functions used to take -1 (negative int) to warn but continue; this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME. * fmt_ident() function implements the above error reporting behaviour common to git_author_info() and git_committer_info(). A symbolic constant IDENT_NO_DATE can be or'ed in to the flag parameter to make it return only the "Name <email@address.xz>". * fmt_name() is a thin wrapper around fmt_ident() that always passes IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

| * Fix parent rewriting in --early-outputLinus Torvalds2007-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot tell a node that has been checked and found not to be interesting (which does not have the TREECHANGE flag) from a node that hasn't been checked if it is interesting or not, without relying on something else, such as object->parsed. But an object can get the "parsed" flag for other reasons. Which means that "TREECHANGE" has the wrong polarity. This changes the way how the path pruning logic marks an uninteresting commits. From now on, we consider a commit interesting by default, and explicitly mark the ones we decided to prune. The flag is renamed to "TREESAME". Then, this fixes the logic to show the early output with incomplete pruning. It basically says "a commit that has TREESAME set is kind-of-UNINTERESTING", but obviously in a different way than an outright UNINTERESTING commit. Until we parse and examine enough parents to determine if a commit becomes surely "kind-of-UNINTERESTING", we avoid rewriting the ancestry so that later rounds can fix things up.

It then just replaces it with a bit that says "prune or not", and if not pruning, every commit gets TREECHANGE. That in turn means that - if (!revs->prune_fn || (flags & TREECHANGE)) - if (revs->prune_fn && !(flags & TREECHANGE)) just become - if (flags & TREECHANGE) - if (!(flags & TREECHANGE)) respectively. Together with adding the "single_parent()" helper function, the "complex" conditional now becomes if (!(flags & TREECHANGE) && rev->dense && single_parent(commit)) continue; Also indirection of "revs->dense" checking is thrown away the same way, because TREECHANGE bit is set appropriately now.

| * Enhance --early-output formatLinus Torvalds2007-11-05

I realize that the "Final output:" line is now illogical, since it's not really final until it also says "done", but It now _always_ generates a "Final output:" header in front of any commit list, and that output header gives you a *guess* at the maximum number of commits available. However, it should be noted that the guess can be completely off: I do a reasonable job estimating it, but it is not meant to be exact. So what happens is that you may get output like this: - at 0.1 seconds: Final output: 2 incomplete .. 2 commits listed .. - half a second later: Final output: 33 incomplete .. 33 commits listed .. - another half a second after that: Final output: 71 incomplete .. 71 commits listed .. - another half second later: Final output: 136 incomplete .. 100 commits listed: we hit the --early-output limit, and .. will only output 100 commits, and after this you'll not .. see an "incomplete" report any more since you got as much .. early output as you asked for! - .. and then finally: Final output: 73106 done .. all the commits .. The above is a real-life scenario on my current kernel tree after having flushed all the caches. Tested with the experimental gitk patch that Paul sent out, and by looking at the actual log output (and verifying that my commit count guesses actually match real life fairly well).

| * Add "--early-output" log flag for interactive GUI useLinus Torvalds2007-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for "--early-output[=n]" as a flag to the "git log" family of commands. This allows GUI programs to state that they want to get some output early, in order to be able to show at least something quickly, even if the full output may take longer to generate. If no count is specified, a default count of a hundred commits will be used, although the actual numbr of commits output may be smaller depending on how many commits were actually found in the first tenth of a second (or if *everything* was found before that, in which case no early output will be provided, and only the final list is made available). When the full list is generated, there will be a "Final output:" string prepended to it, regardless of whether any early commits were shown or not, so that the consumer can always know the difference between early output and the final list.

But no, people keep asking for it, but nobody actually did anything, so I decided I might as well bite the bullet, and instead of telling people they could add a "--follow" flag to "git log" to do what they want to do, I decided that it looks like I just have to do it for them.. The code wasn't actually that complicated, in that the diffstat for this patch literally says "70 insertions(+), 1 deletions(-)", but I will have to admit that in order to get to this fairly simple patch, you did have to know and understand the internal git diff generation machinery pretty well, and had to really be able to follow how commit generation interacts with generating patches and generating the log. So I suspect that while I was right that it wasn't that hard, I might have been expecting too much of random people - this patch does seem to be firmly in the core "Linus or Junio" territory. To make a long story short: I'm sorry for it taking so long until I just did it. I'm not going to guarantee that this works for everybody, but you really can just look at the patch, and after the appropriate appreciative noises ("Ooh, aah") over how clever I am, you can then just notice that the code itself isn't really that complicated. All the real new code is in the new "try_to_follow_renames()" function. It really isn't rocket science: we notice that the pathname we were looking at went away, so we start a full tree diff and try to see if we can instead make that pathname be a rename or a copy from some other previous pathname. And if we can, we just continue, except we show *that* particular diff, and ever after we use the _previous_ pathname. One thing to look out for: the "rename detection" is considered to be a singular event in the _linear_ "git log" output! That's what people want to do, but I just wanted to point out that this patch is *not* carrying around a "commit,pathname" kind of pair and it's *not* going to be able to notice the file coming from multiple *different* files in earlier history. IOW, if you use "git log --follow", then you get the stupid CVS/SVN kind of "files have single identities" kind of semantics, and git log will just pick the identity based on the normal move/copy heuristics _as_if_ the history could be linearized. Put another way: I think the model is broken, but given the broken model, I think this patch does just about as well as you can do. If you have merges with the same "file" having different filenames over the two branches, git will just end up picking _one_ of the pathnames at the point where the newer one goes away. It never looks at multiple pathnames in parallel. And if you understood all that, you probably didn't need it explained, and if you didn't understand the above blathering, it doesn't really mtter to you. What matters to you is that you can now do git log -p --follow builtin-rev-list.c and it will find the point where the old "rev-list.c" got renamed to "builtin-rev-list.c" and show it as such.

* Lift 16kB limit of log message outputJunio C Hamano2007-06-13
| | | | | | | | | | | | | | | | | | | | | 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>
