Bug ID: 6334
Summary: In log -G show first parent of merge changeset to left
of second parent
Product: Mercurial
Version: stable branch
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: feature
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: kkpeng...@gmail.com
CC: mercurial-devel@mercurial-scm.org
Python Version: ---
Currently, when displaying a merge changeset and its ancestors using hg log -G,
Mercurial puts the parent with the lower revision number to the left of the
parent with the higher revision number, so the output looks something like
this:
@ changeset: 3:3f23f61ba894
|\ parent: 2:3af30b7d0b2a
| | parent: 1:d8dfb1a91133
| |
| o changeset: 2:3af30b7d0b2a
| | parent: 0:a8e5bfe19697
| |
o | changeset: 1:d8dfb1a91133
|/
o changeset: 0:a8e5bfe19697
(I omitted user, date, summary and tag lines for brevity.)
This means that, regardless of whether I merge changeset 2 into changeset 1 or
vice versa, the graph that hg log -G outputs looks the same. The only way I can
tell which parent is the first parent of changeset 3 is by reading the "parent"
lines under changeset 3's info.
I think it would be less confusing if Mercurial always displayed the first
parent to the left of the second parent. So if changeset 1 were the first
parent, the graph would look like (omitting boilerplate lines):
@ changeset: 3:3f23f61ba894
|\
| o changeset: 2:3af30b7d0b2a
| |
o | changeset: 1:d8dfb1a91133
|/
o changeset: 0:a8e5bfe19697
while if changeset 2 were the first parent, then the graph would look like
(again omitting boilerplate):
@ changeset: 3:3f23f61ba894
|\
o | changeset: 2:3af30b7d0b2a
| |
| o changeset: 1:d8dfb1a91133
|/
o changeset: 0:a8e5bfe19697
(For comparison, that is what Git currently does.)
