DESCRIPTION
|
|
-----------
|
|
Lists commit objects in reverse chronological order starting at the
|
|
given commit(s), taking ancestry relationship into account. This is
|
|
useful to produce human-readable log output.
|
|
|
|
Commits which are stated with a preceding '{caret}' cause listing to stop at
|
|
that point. Their parents are implied. "git-rev-list foo bar {caret}baz" thus
|
|
means "list all the commits which are included in 'foo' and 'bar', but
|
|
not in 'baz'".
|
|
|
|
A special notation <commit1>..<commit2> can be used as a
|
|
short-hand for {caret}<commit1> <commit2>.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
--pretty::
|
|
Print the contents of the commit changesets in human-readable form.
|
|
|
|
--header::
|
|
Print the contents of the commit in raw-format; each
|
|
record is separated with a NUL character.
|
|
|
|
--objects::
|
|
Print the object IDs of any object referenced by the listed commits.
|
|
'git-rev-list --objects foo ^bar' thus means "send me all object IDs
|
|
which I need to download if I have the commit object 'bar', but
|
|
not 'foo'".
|
|
|
|
--objects-edge::
|
|
Similar to `--objects`, but also print the IDs of
|
|
excluded commits refixed with a `-` character. This is
|
|
used by `git-pack-objects` to build 'thin' pack, which
|
|
records objects in deltified form based on objects
|
|
contained in these excluded commits to reduce network
|
|
traffic.
|
|
|
|
--unpacked::
|
|
Only useful with `--objects`; print the object IDs that
|
|
are not in packs.
|
|
|
|
--bisect::
|
|
Limit output to the one commit object which is roughly halfway
|
|
between the included and excluded commits. Thus, if 'git-rev-list
|
|
--bisect foo ^bar ^baz' outputs 'midpoint', the output
|
|
of 'git-rev-list foo ^midpoint' and 'git-rev-list midpoint
|
|
^bar ^baz' would be of roughly the same length. Finding the change
|
|
which introduces a regression is thus reduced to a binary search:
|
|
repeatedly generate and test new 'midpoint's until the commit chain
|
|
is of length one.
|
|
|
|
--max-count::
|
|
Limit the number of commits output.
|
|
|
|
--max-age=timestamp, --min-age=timestamp::
|
|
Limit the commits output to specified time range.
|
|
|
|
--sparse::
|
|
When optional paths are given, the command outputs only
|
|
the commits that changes at least one of them, and also
|
|
ignores merges that do not touch the given paths. This
|
|
flag makes the command output all eligible commits
|
|
(still subject to count and age limitation), but apply
|
|
merge simplification nevertheless.
|
|
|
|
--remove-empty::
|
|
Stop when a given path disappears from the tree.
|
|
|
|
--all::
|
|
Pretend as if all the refs in `$GIT_DIR/refs/` are
|
|
listed on the command line as <commit>.
|
|
|
|
--topo-order::
|
|
By default, the commits are shown in reverse
|
|
chronological order. This option makes them appear in
|
|
topological order (i.e. descendant commits are shown
|
|
before their parents).
|
|
|
|
--merge-order::
|
|
When specified the commit history is decomposed into a unique
|
|
sequence of minimal, non-linear epochs and maximal, linear epochs.
|
|
Non-linear epochs are then linearised by sorting them into merge
|
|
order, which is described below.
|
|
+
|
|
Maximal, linear epochs correspond to periods of sequential development.
|
|
Minimal, non-linear epochs correspond to periods of divergent development
|
|
followed by a converging merge. The theory of epochs is described in more
|
|
detail at
|
|
link:http://blackcubes.dyndns.org/epoch/[http://blackcubes.dyndns.org/epoch/].
|
|
+
|
|
The merge order for a non-linear epoch is defined as a linearisation for which
|
|
the following invariants are true:
|
|
+
|
|
1. if a commit P is reachable from commit N, commit P sorts after commit N
|
|
in the linearised list.
|
|
2. if Pi and Pj are any two parents of a merge M (with i < j), then any
|
|
commit N, such that N is reachable from Pj but not reachable from Pi,
|
|
sorts before all commits reachable from Pi.
|
|
+
|
|
Invariant 1 states that later commits appear before earlier commits they are
|
|
derived from.
|
|
+
|
|
Invariant 2 states that commits unique to "later" parents in a merge, appear
|
|
before all commits from "earlier" parents of a merge.
|
|
|
|
--show-breaks::
|
|
Each item of the list is output with a 2-character prefix consisting
|
|
of one of: (|), (^), (=) followed by a space.
|
|
+
|
|
Commits marked with (=) represent the boundaries of minimal, non-linear epochs
|
|
and correspond either to the start of a period of divergent development or to
|
|
the end of such a period.
|
|
+
|
|
Commits marked with (|) are direct parents of commits immediately preceding
|
|
the marked commit in the list.
|
|
+
|
|
Commits marked with (^) are not parents of the immediately preceding commit.
|
|
These "breaks" represent necessary discontinuities implied by trying to
|
|
represent an arbitrary DAG in a linear form.
|
|
+
|
|
`--show-breaks` is only valid if `--merge-order` is also specified.
