| * 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.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Rather than expand it with a few new colors, this patch makes the usual config color syntax available, including more colors, backgrounds, and attributes. Because colors are no longer bounded to a single word (e.g., %Cred), this uses a more advanced syntax that features a beginning and end delimiter (but the old syntax still works). So you can now do: git log --pretty=tformat:'%C(yellow)%h%C(reset) %s' to emulate --pretty=oneline, or even git log --pretty=tformat:'%C(cyan magenta bold)%s%C(reset)' if you want to relive the awesomeness of 4-color CGA.

* builtin-blame: Reencode commit messages according to git-log rules.Alexander Gavrilov2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | Currently git-blame outputs text from the commit messages (e.g. the author name and the summary string) as-is, without even providing any information about the encoding used for the data. It makes interpreting the data in multilingual environment very difficult. This commit changes the blame implementation to recode the messages using the rules used by other commands like git-log. Namely, the target encoding can be specified through the i18n.commitEncoding or i18n.logOutputEncoding options, or directly on the command line using the --encoding parameter. Converting the encoding before output seems to be more friendly to the porcelain tools than simply providing the value of the encoding header, and does not require changing the output format. If anybody needs the old behavior, it is possible to achieve it by specifying --encoding=none.

* 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. It adds two tests by Jeff King who independently diagnosed this issue. Signed-off-by: Junio C Hamano <gitster@pobox.com>

E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

| | | | | | | | | | When e-mail address is empty (e.g. "A U Thor <>"), --pretty=format misparsed the commit header and did not pick up the date field correctly. Noticed by Marco, fixed slightly differently with additional sanity check and with a test. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Make "--pretty=format" parser a bit more careful.René Scharfe2007-12-26
| | | | | | | | | When a commit message that does not have a terminating LF is read in and the memory that was allocated to read it happens to have a LF immediately after that, the code was not careful and went past the terminating NUL. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* --format=pretty: avoid calculating expensive expansions twiceRené Scharfe2007-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Jeff King remarked, format strings with duplicate placeholders can be slow to expand, because each instance is calculated anew. This patch makes use of the fact that format_commit_message() and its helper functions only ever add stuff to the end of the strbuf. For certain expensive placeholders, store the offset and length of their expansion with the strbuf at the first occurrence. Later they expansion result can simply be copied from there -- no malloc() or strdup() required. These certain placeholders are the abbreviated commit, tree and parent hashes, as the search for a unique abbreviated hash is quite costly. Here are the times for next (best of three runs): $ time git log --pretty=format:%h >/dev/null real 0m0.611s user 0m0.404s sys 0m0.204s $ time git log --pretty=format:%h%h%h%h >/dev/null real 0m1.206s user 0m0.744s sys 0m0.452s And here those with this patch (and the previous two); the speedup of the single placeholder case is just noise: $ time git log --pretty=format:%h >/dev/null real 0m0.608s user 0m0.416s sys 0m0.192s $ time git log --pretty=format:%h%h%h%h >/dev/null real 0m0.639s user 0m0.488s sys 0m0.140s Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* --pretty=format: parse commit message only onceRené Scharfe2007-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Jeff King pointed out, some placeholder expansions are related to each other: the steps to calculate one go most of the way towards calculating the other, too. This patch makes format_commit_message() parse the commit message only once, remembering the position of each item. This speeds up handling of format strings containing multiple placeholders from the set %s, %a*, %c*, %e, %b. Here are the timings for the git version in next. The first one is to estimate the overhead of the caching, the second one is taken from http://svn.tue.mpg.de/tentakel/trunk/tentakel/Makefile as an example of a format string found in the wild. The times are the fastest of three consecutive runs in each case: $ time git log --pretty=format:%e >/dev/null real 0m0.381s user 0m0.340s sys 0m0.024s $ time git log --pretty=format:"* %cd %cn%n%n%s%n%b" >/dev/null real 0m0.623s user 0m0.556s sys 0m0.052s And here the times with this patch: $ time git log --pretty=format:%e >/dev/null real 0m0.385s user 0m0.332s sys 0m0.040s $ time git log --pretty=format:"* %cd %cn%n%n%s%n%b" >/dev/null real 0m0.563s user 0m0.504s sys 0m0.048s Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* --pretty=format: on-demand format expansionRené Scharfe2007-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the --pretty=format placeholders expansions are expensive to calculate. This is made worse by the current code's use of interpolate(), which requires _all_ placeholders are to be prepared up front. One way to speed this up is to check which placeholders are present in the format string and to prepare only the expansions that are needed. That still leaves the allocation overhead of interpolate(). Another way is to use a callback based approach together with the strbuf library to keep allocations to a minimum and avoid string copies. That's what this patch does. It introduces a new strbuf function, strbuf_expand(). The function takes a format string, list of placeholder strings, a user supplied function 'fn', and an opaque pointer 'context' to tell 'fn' what thingy to operate on. The function 'fn' is expected to accept a strbuf, a parsed placeholder string and the 'context' pointer, and append the interpolated value for the 'context' thingy, according to the format specified by the placeholder. Thanks to Pierre Habouzit for his suggestion to use strchrnul() and the code surrounding its callsite. And thanks to Junio for most of this commit message. :) Here my measurements of most of Paul Mackerras' test cases that highlighted the performance problem (best of three runs): (master) $ time git log --pretty=oneline >/dev/null real 0m0.390s user 0m0.340s sys 0m0.040s (master) $ time git log --pretty=raw >/dev/null real 0m0.434s user 0m0.408s sys 0m0.016s (master) $ time git log --pretty="format:%H {%P} %ct" >/dev/null real 0m1.347s user 0m0.080s sys 0m1.256s (interp_find_active -- Dscho) $ time ./git log --pretty="format:%H {%P} %ct" >/dev/null real 0m0.694s user 0m0.020s sys 0m0.672s (strbuf_expand -- this patch) $ time ./git log --pretty="format:%H {%P} %ct" >/dev/null real 0m0.395s user 0m0.352s sys 0m0.028s Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
