* Introduce new pretty formats %g[sdD] for reflog informationThomas Rast2009-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add three new --pretty=format escapes: %gD long reflog descriptor (e.g. refs/stash@{0}) %gd short reflog descriptor (e.g. stash@{0}) %gs reflog message This is achieved by passing down the reflog info, if any, inside the pretty_print_context struct. We use the newly refactored get_reflog_selector(), and give it some extra functionality to extract a shortened ref. The shortening is cached inside the commit_reflogs struct; the only allocation of it happens in read_complete_reflog(), where it is initialised to 0. Also add another helper get_reflog_message() for the message extraction. Note that the --format="%h %gD: %gs" tests may not work in real repositories, as the --pretty formatter doesn't know to leave away the ": " on the last commit in an incomplete (because git-gc removed the old part) reflog. This equivalence is nevertheless the main goal of this patch. Thanks to Jeff King for reviews, the %gd testcase and documentation.

* Refactor pretty_print_commit arguments into a structThomas Rast2009-10-19
| | | | | | | | | | | | | | | | | pretty_print_commit() has a bunch of rarely-used arguments, and introducing more of them requires yet another update of all the call sites. Refactor most of them into a struct to make future extensions easier. The ones that stay "plain" arguments were chosen on the grounds that all callers put real arguments there, whereas some callers have 0/NULL for all arguments that were factored into the struct. We declare the struct 'const' to ensure none of the callers are bitten by the changed (no longer call-by-value) semantics.

* Let --decorate show HEAD positionThomas Rast2009-10-12
| | | | | | | | | | 'git log --graph --oneline --decorate --all' is a useful way to get a general overview of the repository state, similar to 'gitk --all'. Let it indicate the position of HEAD by loading that ref too, so that the --decorate code can see it.

* 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.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, format-patch can only track a single reference (the In-Reply-To:) for each mail. To ensure proper threading, we should list all known references for every mail. Change the rev_info.ref_message_id field to a string_list, so that we can append references at will, and change the output formatting routines to print all of them in the References: header. The last entry in the list is implicitly assumed to be the In-Reply-To:, which gives output consistent with RFC 2822: The "References:" field will contain the contents of the parent's "References:" field (if any) followed by the contents of the parent's "Message-ID:" field (if any). Note that this is just preparatory work; nothing uses it yet, so all "References:" fields in the output are still only one deep.

* log: do not print ellipses with --abbrev-commitThomas Rast2009-02-13
| | | | | | | | | | | | | | | 'git log --abbrev-commit' added an ellipsis to all commit names that were abbreviated. This was particularly annoying if you wanted to cut&paste the sha1 from the terminal, since selecting by word would pick up '...' too. So use find_unique_abbrev() instead of diff_unique_abbrev() in all log-related commit sha1 printing routines, and also change the formatting of the 'Merge: parent1 parent2' line output via pretty_print_commit().

* Fix machine-parseability of 'git log --source'Linus Torvalds2008-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | | The space between the commit and the source attribute is not easily machine-parseable: if we combine --source with --parents and give a SHA1 as a starting point, it's unnecessarily hard to see where the list of parents ends and the source decoration begins. Example: git show --parents --source $(git rev-list HEAD) which is admittedly contrived, but can easily happen in scripting. So use a <tab> instead of a space as the source separator. The other decorations didn't have this issue, because they were surrounded by parenthesis, so it's obvious that they aren't parent SHA1's. It so happens that _visually_ this makes no difference for "git log --source", since "commit <40-char SHA1>" is 47 characters, so both a space and a <tab> will end up showing as a single commit. Of course, with '--pretty=oneline' or '--parents' or '--abbrev-commit' you'll see the difference.

| | | | | | | | | | | | | | | | | We already support decorating commits by tags or branches that point to them, but especially when we are looking at multiple branches together, we sometimes want to see _how_ we reached a particular commit. 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.

* format-patch: Produce better output with --inline or --attachKevin Ballard2008-07-29
| | | | | | | | | | | | | | | | | | | | This patch makes two small changes to improve the output of --inline and --attach. The first is to write a newline preceding the boundary. This is needed because MIME defines the encapsulation boundary as including the preceding CRLF (or in this case, just LF), so we should be writing one. Without this, the last newline in the pre-diff content is consumed instead. The second change is to always write the line termination character (default: newline) even when using --inline or --attach. This is simply to improve the aesthetics of the resulting message. When using --inline an email client should render the resulting message identically to the non-inline version. And when using --attach this adds a blank line preceding the attachment in the email, which is visually attractive.

* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, the callchain from pretty_print_commit() down to pp_title_line() had an unwarranted assumption that the presense of "after_subject" parameter, means the caller has already output MIME headers for attachments. The parameter's primary purpose is to give extra header lines the caller wants to place after pp_title_line() generates the "Subject: " line. This assumption does not hold when the user used the format.header configuration variable to pass extra headers, and caused a message with non-ASCII character to lack proper MIME headers (e.g. 8-bit CTE header). The earlier logic also failed to suppress duplicated MIME headers when "format-patch -s --attach" is asked for and the signer's name demanded 8-bit clean transport. This patch fixes the logic by introducing a separate need_8bit_cte parameter passed down the callchain. This can have one of these values: -1 : we've already done MIME crap and we do not want to add extra header to say this is 8bit in pp_title_line(); 0 : we haven't done MIME and we have not seen anything that is 8bit yet; 1 : we haven't done MIME and we have seen something that is 8bit; pp_title_line() must add MIME header.

* | Add "--show-all" revision walker flag for debuggingLinus Torvalds2008-02-13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's really not very easy to visualize the commit walker, because - on purpose - it obvously doesn't show the uninteresting commits! This adds a "--show-all" flag to the revision walker, which will make it show uninteresting commits too, and they'll have a '^' in front of them (it also fixes a logic error for !verbose_header for boundary commits - we should show the '-' even if left_right isn't shown). A separate patch to gitk to teach it the new '^' was sent to paulus. With the change in place, it actually is interesting even for the cases that git doesn't have any problems with, ie for the kernel you can do: gitk -d --show-all v2.6.24.. and you see just how far down it has to parse things to see it all. The use of "-d" is a good idea, since the date-ordered toposort is much better at showing why it goes deep down (ie the date of some of those commits after 2.6.24 is much older, because they were merged from trees that weren't rebased). So I think this is a useful feature even for non-debugging - just to visualize what git does internally more. When it actually breaks out due to the "everybody_uninteresting()" case, it adds the uninteresting commits (both the one it's looking at now, and the list of pending ones) to the list This way, we really list *all* the commits we've looked at. Because we now end up listing commits we may not even have been parsed at all "show_log" and "show_commit" need to protect against commits that don't have a commit buffer entry. That second part is debatable just how it should work. Maybe we shouldn't show such entries at all (with this patch those entries do get shown, they just don't get any message shown with them). But I think this is a useful case. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This patch skips the fflush() calls when stdout is a regular file, or if the environment variable GIT_FLUSH is set to "0".

| | | | | | | | | | | | | | | | | | | | | 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>

* | Add --date={local,relative,default}Junio C Hamano2007-04-25
| | | | | | | | | | | | | | | | | | | | | | This adds --date={local,relative,default} option to log family of commands, to allow displaying timestamps in user's local timezone, relative time, or the default format. Existing --relative-date option is a synonym of --date=relative; we could probably deprecate it in the long run. Signed-off-by: Junio C Hamano <junkio@cox.net>
