We need special handling for repositories with no "default" branch because
|
|
|
"null" revision belongs to non-existent "default" branch.
|
|
|
|
|
|
$ hg init nodefault
|
|
|
$ cd nodefault
|
|
|
$ hg branch -q foo
|
|
|

$ hg ci -Aqm0

|

|
|

$ hg branch -q bar
|
|
|
$ touch 2
|

$ hg update -qr0

$ hg branch -q baz
|

$ touch 3

$ hg ci -Aqm3

|

|
|

|
|
|
a) updating from "null" should bring us to the tip-most branch head as
|
|
|
there is no "default" branch:
|
|
|
|
|
|
$ hg update -q null
|
|
|
$ hg id -bn
|
|
|
-1 default
|
|
|
$ hg update
|
|
|
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
|
|
|
$ hg id -bn
|
|
|
2 bar
|
|
|
|
|
|
b) but if we are at uncommitted "default" branch, we should stick to the
|
|
|
current revision:
|
|
|
|
|
|
$ hg update -q 0
|
|
|
$ hg branch default
|
|
|
marked working directory as branch default
|
|
|
$ hg id -bn
|
|
|
0 default
|
|
|
$ hg update
|
|
|
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
|
|
|
$ hg id -bn
|
|
|
0 default
|
|
|
|
|
|
c) also, if we have uncommitted branch at "null", we should stick to it:
|
|
|
|
|
|
$ hg update -q null
|
|
|
$ hg branch new
|
|
|
marked working directory as branch new
|
|
|
$ hg id -bn
|
|
|
-1 new
|
|
|
$ hg update
