NAME |
|
---- |
|
git-rev-list - Lists commit objects in reverse chronological order |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
'git-rev-list' [ *--max-count*=number ] [ *--max-age*=timestamp ] [ *--min-age*=timestamp ] [ *--bisect* ] [ *--pretty* ] [ *--objects* ] [ *--merge-order* [ *--show-breaks* ] ] <commit> [ <commit> ...] [ ^<commit> ...] |
|
|
|
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 '^' cause listing to stop at |
|
that point. Their parents are implied. "git-rev-list foo bar ^baz" thus |
|
means "list all the commits which are included in 'foo' and 'bar', but |
|
not in 'baz'". |
|
|
|
OPTIONS |
|
------- |
|
--pretty:: |
|
Print the contents of the commit changesets in human-readable form. |
|
|
|
--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'". |
|
|
|
--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. |
|
|
|
--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 arbtirary DAG in a linear form. |
|
+ |
|
*--show-breaks* is only valid if *--merge-order* is also specified. |
