revset: add new topographical sort
Sort revisions in reverse revision order but grouped by topographical branches.
Visualised as a graph, instead of:
o 4
|
| o 3
| |
| o 2
| |
o | 1
|/
o 0
revisions on a 'main' branch are emitted before 'side' branches:
o 4
|
o 1
|
| o 3
| |
| o 2
|/
o 0
where what constitutes a 'main' branch is configurable, so the sort could also
result in:
o 3
|
o 2
|
| o 4
| |
| o 1
|/
o 0
This sort was already available as an experimental option in the graphmod
module, from which it is now removed.
This sort is best used with hg log -G:
$ hg log -G "sort(all(), topo)"
This test file aims at test topological iteration and the various configuration it can has.
$ cat >> $HGRCPATH << EOF
> [ui]
> logtemplate={rev}\n
> EOF
On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
$ hg init test01
$ cd test01
$ hg unbundle $TESTDIR/bundles/remote.hg

adding file changes
added 9 changesets with 7 changes to 4 files (+1 heads)
(run 'hg heads' to see heads, 'hg merge' to merge)
