When `log --decorate` is used, git will decorate commits with all
available refs. While in most cases this may give the desired effect,
under some conditions it can lead to excessively verbose output.
Introduce two command line options, `--decorate-refs=<pattern>` and
`--decorate-refs-exclude=<pattern>` to allow the user to select which
refs are used in decoration.
When "--decorate-refs=<pattern>" is given, only the refs that match the
pattern are used in decoration. The refs that match the pattern when
"--decorate-refs-exclude=<pattern>" is given, are never used in
decoration.
These options follow the same convention for mixing negative and
positive patterns across the system, assuming that the inclusive default
is to match all refs available.
(1) if there is no positive pattern given, pretend as if an
inclusive default positive pattern was given;
(2) for each candidate, reject it if it matches no positive
pattern, or if it matches any one of the negative patterns.
The rules for what is considered a match are slightly different from the
rules used elsewhere.
Commands like `log --glob` assume a trailing '/*' when glob chars are
not present in the pattern. This makes it difficult to specify a single
ref. On the other hand, commands like `describe --match --all` allow
specifying exact refs, but do not have the convenience of allowing
"shorthand refs" like 'refs/heads' or 'heads' to refer to
'refs/heads/*'.
The commands introduced in this patch consider a match if:
(a) the pattern contains globs chars,
and regular pattern matching returns a match.
(b) the pattern does not contain glob chars,
and ref '<pattern>' exists, or if ref exists under '<pattern>/'
This allows both behaviours (allowing single refs and shorthand refs)
yet remaining compatible with existent commands.

NAME

|
----
|
|
git-log - Show commit logs
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'git log' [<options>] [<revision range>] [[\--] <path>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Shows the commit logs.
|
|
|
|
The command takes options applicable to the `git rev-list`
|
|
command to control what is shown and how, and options applicable to
|
|
the `git diff-*` commands to control how the changes
|
|
each commit introduces are shown.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
--follow::
|
|
Continue listing the history of a file beyond renames
|
|
(works only for a single file).
|
|
|
|
--no-decorate::
|
|
--decorate[=short|full|auto|no]::
|
|
Print out the ref names of any commits that are shown. If 'short' is
|
|
specified, the ref name prefixes 'refs/heads/', 'refs/tags/' and
|
|
'refs/remotes/' will not be printed. If 'full' is specified, the
|
|
full ref name (including prefix) will be printed. If 'auto' is
|
|
specified, then if the output is going to a terminal, the ref names
|
|
are shown as if 'short' were given, otherwise no ref names are
|
|
shown. The default option is 'short'.
|
|
|
|
--decorate-refs=<pattern>::
|
|
--decorate-refs-exclude=<pattern>::
|
|
If no `--decorate-refs` is given, pretend as if all refs were
|
|
included. For each candidate, do not use it for decoration if it
|
|
matches any patterns given to `--decorate-refs-exclude` or if it
|
|
doesn't match any of the patterns given to `--decorate-refs`.
|
|
|
|
--source::
|
|
Print out the ref name given on the command line by which each
|
|
commit was reached.
|
|
|
|
--use-mailmap::
|
|
Use mailmap file to map author and committer names and email
|
|
addresses to canonical real names and email addresses. See
|
|
linkgit:git-shortlog[1].
|
|
|
|
--full-diff::
|
|
Without this flag, `git log -p <path>...` shows commits that
|
|
touch the specified paths, and diffs about the same specified
|
|
paths. With this, the full diff is shown for commits that touch
|
|
the specified paths; this means that "<path>..." limits only
|
|
commits, and doesn't limit diff for those commits.
|
|
+
|
|
Note that this affects all diff-based output types, e.g. those
|
|
produced by `--stat`, etc.
|
|
|
|
--log-size::
|
|
Include a line ``log size <number>'' in the output for each commit,
|
|
where <number> is the length of that commit's message in bytes.
|
|
Intended to speed up tools that read log messages from `git log`
|
|
output by allowing them to allocate space in advance.
|
|
|
|
-L <start>,<end>:<file>::
|
|
-L :<funcname>:<file>::
|
|
Trace the evolution of the line range given by "<start>,<end>"
|
|
(or the function name regex <funcname>) within the <file>. You may
|
|
not give any pathspec limiters. This is currently limited to
|
|
a walk starting from a single revision, i.e., you may only
|
|
give zero or one positive revision arguments.
|
|
You can specify this option more than once.
|
|
+
|
|
include::line-range-format.txt[]
|
|
|
|
<revision range>::
|
|
Show only commits in the specified revision range. When no
|
|
<revision range> is specified, it defaults to `HEAD` (i.e. the
|
|
whole history leading to the current commit). `origin..HEAD`
|
|
specifies all the commits reachable from the current commit
|
|
(i.e. `HEAD`), but not from `origin`. For a complete list of
|
|
ways to spell <revision range>, see the 'Specifying Ranges'
|
|
section of linkgit:gitrevisions[7].
|
|
|
|
[\--] <path>...::
|
|
Show only commits that are enough to explain how the files
|
|
that match the specified paths came to be. See 'History
|
|
Simplification' below for details and other simplification
|
|
modes.
|
|
+
|
|
Paths may need to be prefixed with ``\-- '' to separate them from
|
|
options or the revision range, when confusion arises.

EXAMPLES
|
|
--------
|
|
`git log --no-merges`::
|
|
|
|
Show the whole commit history, but skip any merges
|
|
|
|
`git log v2.6.12.. include/scsi drivers/scsi`::
|
|
|
|
Show all commits since version 'v2.6.12' that changed any file
|
|
in the `include/scsi` or `drivers/scsi` subdirectories
|
|
|
|
`git log --since="2 weeks ago" -- gitk`::
|
|
|
|
Show the changes during the last two weeks to the file 'gitk'.
|
|
The ``--'' is necessary to avoid confusion with the *branch* named
|
|
'gitk'
|
|
|
|
`git log --name-status release..test`::
|
|
|
|
Show the commits that are in the "test" branch but not yet
|
|
in the "release" branch, along with the list of paths
|
|
each commit modifies.
|
|
|
|
`git log --follow builtin/rev-list.c`::
|
|
|
|
Shows the commits that changed `builtin/rev-list.c`, including
|
|
those commits that occurred before the file was given its
|
|
present name.
|
|
|
|
`git log --branches --not --remotes=origin`::
|
|
|
|
Shows all commits that are in any of local branches but not in
|
|
any of remote-tracking branches for 'origin' (what you have that
|
|
origin doesn't).
|
|
|
|
`git log master --not --remotes=*/master`::
|
|
|
|
Shows all commits that are in local master but not in any remote
|
|
repository master branches.
|
|
|
|
`git log -p -m --first-parent`::
|
|
|
|
Shows the history including change diffs, but only from the
|
|
``main branch'' perspective, skipping commits that come from merged
|
|
branches, and showing full diffs of changes introduced by the merges.
|
|
This makes sense only when following a strict policy of merging all
|
|
topic branches when staying on a single integration branch.
|
|
|
|
`git log -L '/int main/',/^}/:main.c`::
|
|
|
|
Shows how the function `main()` in the file `main.c` evolved
|
|
over time.
|
|
|
|
`git log -3`::
|
|
|
|
Limits the number of commits to show to 3.

|
CONFIGURATION
|
|
-------------
|
|
|
|
See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
|
|
for settings related to diff generation.
|
|
|
|
format.pretty::
|
|
Default for the `--format` option. (See 'Pretty Formats' above.)
|
|
Defaults to `medium`.
|
|
|
|
i18n.logOutputEncoding::
|
|
Encoding to use when displaying logs. (See 'Discussion' above.)
|
|
Defaults to the value of `i18n.commitEncoding` if set, and UTF-8
|
|
otherwise.
|
|
|
|
log.date::
|
|
Default format for human-readable dates. (Compare the
|
|
`--date` option.) Defaults to "default", which means to write
|
|
dates like `Sat May 8 19:35:34 2010 -0500`.
|
|
|
|
log.follow::
|
|
If `true`, `git log` will act as if the `--follow` option was used when
|
|
a single <path> is given. This has the same limitations as `--follow`,
|
|
i.e. it cannot be used to follow multiple files and does not work well
|
|
on non-linear history.
|
|
|
|
log.showRoot::
|
|
If `false`, `git log` and related commands will not treat the
|
|
initial commit as a big creation event. Any root commits in
|
|
`git log -p` output would be shown without a diff attached.
|
|
The default is `true`.
|
|
|
|
log.showSignature::
|
|
If `true`, `git log` and related commands will act as if the
|
|
`--show-signature` option was passed to them.
|
|
|
|
mailmap.*::
|
|
See linkgit:git-shortlog[1].
|
|
|
|
notes.displayRef::
|
|
Which refs, in addition to the default set by `core.notesRef`
|
|
or `GIT_NOTES_REF`, to read notes from when showing commit
|
|
messages with the `log` family of commands. See
|
|
linkgit:git-notes[1].
|
|
+
|
|
May be an unabbreviated ref name or a glob and may be specified
|
|
multiple times. A warning will be issued for refs that do not exist,
|
|
but a glob that does not match any refs is silently ignored.
|
|
+
|
|
This setting can be disabled by the `--no-notes` option,
|
|
overridden by the `GIT_NOTES_DISPLAY_REF` environment variable,
|
|
and overridden by the `--notes=<ref>` option.
