2014-07-09log: fix indentation for --graph --show-signatureLibravatar Zoltan Klinger1-0/+1
The git log --graph --show-signature command incorrectly indents the gpg information about signed commits and merged signed tags. It does not follow the level of indentation of the current commit.

2014-06-13reuse cached commit buffer when parsing signaturesLibravatar Jeff King1-1/+1
When we call show_signature or show_mergetag, we read the commit object fresh via read_sha1_file and reparse its headers. However, in most cases we already have the object data available, attached to the "struct commit". This is partially laziness in dealing with the memory allocation issues, but partially defensive programming, in that we would always want to verify a clean version of the buffer (not one that might have been munged by other users of the commit). However, we do not currently ever munge the commit buffer, and not using the already-available buffer carries a fairly big performance penalty when we are looking at a large number of commits. Here are timings on linux.git: [baseline, no signatures] $ time git log >/dev/null real 0m4.902s user 0m4.784s sys 0m0.120s [before] $ time git log --show-signature >/dev/null real 0m14.735s user 0m9.964s sys 0m0.944s [after] $ time git log --show-signature >/dev/null real 0m9.981s user 0m5.260s sys 0m0.936s Note that our user CPU time drops almost in half, close to the non-signature case, but we do still spend more wall-clock and system time, presumably from dealing with gpg. An alternative to this is to note that most commits do not have signatures (less than 1% in this repo), yet we pay the re-parsing cost for every commit just to find out if it has a mergetag or signature. If we checked that when parsing the commit initially, we could avoid re-examining most commits later on. Even if we did pursue that direction, however, this would still speed up the cases where we _do_ have signatures. So it's probably worth doing either way.

2014-06-13commit: record buffer length in cacheLibravatar Jeff King1-1/+1
Most callsites which use the commit buffer try to use the cached version attached to the commit, rather than re-reading from disk. Unfortunately, that interface provides only a pointer to the NUL-terminated buffer, with no indication of the original length. For the most part, this doesn't matter. People do not put NULs in their commit messages, and the log code is happy to treat it all as a NUL-terminated string. However, some code paths do care. For example, when checking signatures, we want to be very careful that we verify all the bytes to avoid malicious trickery. This patch just adds an optional "size" out-pointer to get_commit_buffer and friends. The existing callers all pass NULL (there did not seem to be any obvious sites where we could avoid an immediate strlen() call, though perhaps with some further refactoring we could).

2014-06-13use get_cached_commit_buffer where appropriateLibravatar Jeff King1-1/+1
Some call sites check commit->buffer to see whether we have a cached buffer, and if so, do some work with it. In the long run we may want to switch these code paths to make their decision on a different boolean flag (because checking the cache may get a little more expensive in the future). But for now, we can easily support them by converting the calls to use get_cached_commit_buffer. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-12-20log: properly handle decorations with chained tagsLibravatar brian m. carlson1-0/+2
git log did not correctly handle decorations when a tag object referenced another tag object that was no longer a ref, such as when the second tag was deleted. The commit would not be decorated correctly because parse_object had not been called on the second tag and therefore its tagged field had not been filled in, resulting in none of the tags being associated with the relevant commit. Call parse_object to fill in this field if it is absent so that the chain of tags can be dereferenced and the commit can be properly decorated. Include tests as well to prevent future regressions.

2013-08-01log: use true parents for diff even when rewritingLibravatar Thomas Rast1-1/+1
When using pathspec filtering in combination with diff-based log output, parent simplification happens before the diff is computed. The diff is therefore against the *simplified* parents. This works okay, arguably by accident, in the normal case: simplification reduces to one parent as long as the commit is TREESAME to it. So the simplified parent of any given commit must have the same tree contents on the filtered paths as its true (unfiltered) parent. However, --full-diff breaks this guarantee, and indeed gives pretty spectacular results when comparing the output of git log --graph --stat ... git log --graph --full-diff --stat ... (--graph internally kicks in parent simplification, much like --parents). To fix it, store a copy of the parent list before simplification (in a slab) whenever --full-diff is in effect. Then use the stored parents instead of the simplified ones in the commit display code paths. The latter do not actually check for --full-diff to avoid duplicated code; they just grab the original parents if save_parents() has not been called for this revision walk. For ordinary commits it should be obvious that this is the right thing to do. Merge commits are a bit subtle. Observe that with default simplification, merge simplification is an all-or-nothing decision: either the merge is TREESAME to one parent and disappears, or it is different from all parents and the parent list remains intact. Redundant parents are not pruned, so the existing code also shows them as a merge. So if we do show a merge commit, the parent list just consists of the rewrite result on each parent. Running, e.g., --cc on this in --full-diff mode is not very useful: if any commits were skipped, some hunks will disagree with all sides of the merge (with one side, because commits were skipped; with the others, because they didn't have those changes in the first place). This triggers --cc showing these hunks spuriously. Therefore I believe that even for merge commits it is better to show the diffs wrt. the original parents.

2013-07-03teach format-patch to place other authors into in-body "From"Libravatar Jeff King1-0/+2
Format-patch generates emails with the "From" address set to the author of each patch. If you are going to send the emails, however, you would want to replace the author identity with yours (if they are not the same), and bump the author identity to an in-body header. Normally this is handled by git-send-email, which does the transformation before sending out the emails. However, some workflows may not use send-email (e.g., imap-send, or a custom script which feeds the mbox to a non-git MUA). They could each implement this feature themselves, but getting it right is non-trivial (one must canonicalize the identities by reversing any RFC2047 encoding or RFC822 quoting of the headers, which has caused many bugs in send-email over the years). This patch takes a different approach: it teaches format-patch a "--from" option which handles the ident check and in-body header while it is writing out the email. It's much simpler to do at this level (because we haven't done any quoting yet), and any workflow based on format-patch can easily turn it on.

2013-06-26pretty: --format output should honor logOutputEncodingLibravatar Alexey Shumkin1-0/+1
One can set an alias $ git config [--global] alias.lg "log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cd) %C(bold blue)<%an>%Creset' --abbrev-commit --date=local" to see the log as a pretty tree (like *gitk* but in a terminal). However, log messages written in an encoding i18n.commitEncoding which differs from terminal encoding are shown corrupted even when i18n.logOutputEncoding and terminal encoding are the same (e.g. log messages committed on a Cygwin box with Windows-1251 encoding seen on a Linux box with a UTF-8 encoding and vice versa). To simplify an example we can say the following two commands are expected to give the same output to a terminal: $ git log --oneline --no-color $ git log --pretty=format:'%h %s' However, the former pays attention to i18n.logOutputEncoding configuration, while the latter does not when it formats "%s". The same corruption is true for $ git diff --submodule=log and $ git rev-list --pretty=format:%s HEAD and $ git reset --hard This patch makes pretty --format honor logOutputEncoding when it formats log message.

2013-03-28Implement line-history search (git log -L)Libravatar Thomas Rast1-0/+4
This is a rewrite of much of Bo's work, mainly in an effort to split it into smaller, easier to understand routines. The algorithm is built around the struct range_set, which encodes a series of line ranges as intervals [a,b). This is used in two contexts: * A set of lines we are tracking (which will change as we dig through history). * To encode diffs, as pairs of ranges. The main routine is range_set_map_across_diff(). It processes the diff between a commit C and some parent P. It determines which diff hunks are relevant to the ranges tracked in C, and computes the new ranges for P. The algorithm is then simply to process history in topological order from newest to oldest, computing ranges and (partial) diffs. At branch points, we need to merge the ranges we are watching. We will find that many commits do not affect the chosen ranges, and mark them TREESAME (in addition to those already filtered by pathspec limiting). Another pass of history simplification then gets rid of such commits. This is wired as an extra filtering pass in the log machinery. This currently only reduces code duplication, but should allow for other simplifications and options to be used. Finally, we hook a diff printer into the output chain. Ideally we would wire directly into the diff logic, to optionally use features like word diff. However, that will require some major reworking of the diff chain, so we completely replace the output with our own diff for now. As this was a GSoC project, and has quite some history by now, many people have helped.

2013-03-28Avoid loading commits twice in log with diffsLibravatar Thomas Rast1-3/+10
If you run a log with diffs (such as -p, --raw, --stat etc.) the current code ends up loading many objects twice. For example, for 'log -3000 -p' my instrumentation said the objects loaded more than once are distributed as follows: 2008 blob 2103 commit 2678 tree Fixing blobs and trees will be harder, because those are really used within the diff engine and need some form of caching. However, fixing the commits is easy at least at the band-aid level. They are triggered by log_tree_diff() invoking diff_tree_sha1() on commits, which duly loads the specified object to dereference it to a tree. Since log_tree_diff() knows that it works with commits and they must have trees, we can simply pass through the trees. We add some parse_commit() calls. The ones for the parents are required; we do not know at this stage if they have been looked at. The one for the commit itself is pure paranoia, but has about the same cost as an assertion on commit->object.parsed. This has a quite dramatic effect on log --raw, though only a negligible impact on log -p: Test this tree HEAD -------------------------------------------------------------------- 4000.2: log --raw -3000 0.50(0.43+0.06) 0.54(0.46+0.06) +7.0%*** 4000.3: log -p -3000 2.34(2.20+0.13) 2.37(2.22+0.13) +1.2% -------------------------------------------------------------------- Significance hints: '.' 0.1 '*' 0.05 '**' 0.01 '***' 0.001 Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Thomas Rast <trast@inf.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The --reroll-count=$N option, when given a positive integer: - Adds " v$N" to the subject prefix specified. As the default subject prefix string is "PATCH", --reroll-count=2 makes it "PATCH v2". - Prefixes "v$N-" to the names used for output files. The cover letter, whose name is usually 0000-cover-letter.patch, becomes v2-0000-cover-letter.patch when given --reroll-count=2. This allows users to use the same --output-directory for multiple iterations of the same series, without letting the output for a newer round overwrite output files from the earlier rounds. The user can incorporate materials from earlier rounds to update the newly minted iteration, and use "send-email v2-*.patch" to send out the patches belonging to the second iteration easily.

Most functions that emit to a strbuf take the strbuf as their first parameter; make this function follow suit. The serial number of the patch being emitted (nr) and suffix used for patch filename (suffix) are both recorded in rev_info; drop these separate parameters and pass the rev_info directly.

2012-12-17log --format: teach %C(auto,black) to respect color configLibravatar Junio C Hamano1-0/+1
Traditionally, %C(color attr) always emitted the ANSI color sequence; it was up to the scripts that wanted to conditionally color their output to omit %C(...) specifier when they do not want colors. Optionally allow "auto," to be prefixed to the color, so that the output is colored iff we would color regular "log" output (e.g., taking into account color.* and --color command line options).

2012-11-13format-patch: add a blank line between notes and diffstatLibravatar Junio C Hamano1-10/+21
The last line of the note text comes immediately before the diffstat block, making the latter unnecessarily harder to view. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-10-17format-patch --notes: show notes after three-dashesLibravatar Junio C Hamano1-4/+11
When inserting the note after the commit log message to format-patch output, add three dashes before the note. Record the fact that we did so in the rev_info and omit showing duplicated three dashes in the usual codepath that is used when notes are not being shown.

2012-10-17format-patch: append --signature after notesLibravatar Junio C Hamano1-2/+4
When appending a new signature with "format-patch --signature", if the "--notes" option is also in effect, the location of the new signature (and if the signature should be added in the first place) should be decided using the contents of the original commit log message, before the message from the notes is added.

2012-10-17pretty_print_commit(): do not append notes messageLibravatar Junio C Hamano1-0/+3
The only case pretty_print_commit() appends notes message to the log message taken from the commit is when show_log() calls it with the notes_message field set, and the output format is not the userformat (i.e. when substituting "%N"). No other users of this function sets this field in the pretty_print_context, as can be easily verified in the previous step. Hoist the code to append the notes message to the caller. Up to this point, no functionality change is intended. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-10-17pretty: prepare notes message at a centralized placeLibravatar Junio C Hamano1-1/+13
Instead of passing a boolean show_notes around, pass an optional string that is to be inserted after the log message proper is shown. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-05-22format-patch: refactor get_patch_filenameLibravatar Jeff King1-8/+11
The get_patch_filename function expects a commit argument and uses it to get the sanitized subject line when making a patch filename. However, we also want to use this same function for the cover letter, which does not have a commit object. The current solution is to create a fake commit with the subject "cover letter". Instead, let's make the get_patch_filename interface more flexibile, and allow passing a direct subject. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-05-11Merge branch 'jk/maint-reflog-walk-count-vs-time'Libravatar Junio C Hamano1-4/+4
Gives a better DWIM behaviour for --pretty=format:%gd, "stash list", and "log -g", depending on how the starting point ("master" vs "master@{0}" vs "master@{now}") and date formatting options (e.g. "--date=iso") are given on the command line.

2012-05-07reflog-walk: tell explicit --date=default from not having --date at allLibravatar Junio C Hamano1-4/+3
Introduction of opt->date_mode_explicit was a step in the right direction, but lost that crucial bit at the very end of the callchain, and the callee could not tell an explicitly specified "I want *date* but in default format" from the built-in default value passed when there was no --date specified.

2012-05-07Merge branch 'jk/maint-tformat-with-z'Libravatar Junio C Hamano1-1/+1
"log -z --pretty=tformat:..." does not terminate each record with NUL and this is a beginning of an attempt to fix it. It still is not right but the patch does not make externally observable behaviour worse.
