This is purely indenting under an unconditional branch, so that the actual
changes in the next patch are clear. Feel free to fold them if desired.

$ hg init
$ echo a > a
$ mkdir b
$ echo b > b/b
$ hg commit -A -m "a is file, b is dir"
adding a
adding b/b
File replaced with directory:
$ rm a
$ mkdir a
$ echo a > a/a
Should fail - would corrupt dirstate:
$ hg add a/a
abort: file 'a' in dirstate clashes with 'a/a'
[255]
Removing shadow:
$ hg rm --after a
Should succeed - shadow removed:
$ hg add a/a
Directory replaced with file:
$ rm -r b
$ echo b > b
Should fail - would corrupt dirstate:
$ hg add b
abort: directory 'b' already in dirstate
[255]
Removing shadow:
$ hg rm --after b/b
Should succeed - shadow removed:
$ hg add b
Look what we got:
$ hg st
A a/a
A b
R a
R b/b
Revert reintroducing shadow - should fail:
$ rm -r a b
$ hg revert b/b
abort: file 'b' in dirstate clashes with 'b/b'
[255]
Revert all - should succeed:
$ hg revert --all
undeleting a
forgetting a/a (glob)
forgetting b
undeleting b/b (glob)
$ hg st
Issue3423:
$ hg forget a
$ echo zed > a
$ hg revert a
$ hg st
? a.orig
$ rm a.orig
addremove:
$ rm -r a b
$ mkdir a
$ echo a > a/a
$ echo b > b
$ hg addremove -s 0
removing a
adding a/a
adding b
removing b/b
$ hg st
A a/a
A b
R a
R b/b
commit:
$ hg ci -A -m "a is dir, b is file"
$ hg st --all
C a/a
C b
Long directory replaced with file:
$ mkdir d
$ mkdir d/d
$ echo d > d/d/d
$ hg commit -A -m "d is long directory"
adding d/d/d
$ rm -r d
$ echo d > d
Should fail - would corrupt dirstate:
$ hg add d
abort: directory 'd' already in dirstate
[255]
Removing shadow:
$ hg rm --after d/d/d
Should succeed - shadow removed:
$ hg add d
$ hg ci -md
Update should work at least with clean working directory:
$ rm -r a b d
$ hg up -r 0
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg st --all
C a
C b/b
$ rm -r a b
$ hg up -r 1
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg st --all
C a/a
C b
