subrepo: rewrite handling of subrepo state at commit (issue2403)
When the contents of .hgsubstate are stale (either because they've
manually been tweaked or partial updates have confused it), we get
confused about whether it actually needs committing.
So instead, we actively consult the parent's substate and compare it
the actual current state when deciding whether it needs committing.
Side effect: lots of "committing subrepo" messages that didn't
correspond with real commits disappear.
This change is fairly invasive for a fairly obscure condition, so it's
kept on the default branch.
Create test repository:
$ hg init repo
$ cd repo
$ echo x1 > x.txt
$ hg init foo
$ cd foo
$ echo y1 > y.txt
$ hg init bar
$ cd bar
$ echo z1 > z.txt
$ cd ..
$ echo 'bar = bar' > .hgsub
$ cd ..
$ echo 'foo = foo' > .hgsub
Add files --- .hgsub files must go first to trigger subrepos:
$ hg add -S .hgsub
$ hg add -S foo/.hgsub
$ hg add -S foo/bar
adding foo/bar/z.txt (glob)
$ hg add -S
adding x.txt
adding foo/y.txt (glob)
Test recursive status without committing anything:
$ hg status -S
A .hgsub
A foo/.hgsub
A foo/bar/z.txt
A foo/y.txt
A x.txt
Test recursive diff without committing anything:
$ hg diff --nodates -S foo
diff -r 000000000000 foo/.hgsub
