log: fix handling of root (or empty) path provided by matcher (issue6478)
Since 27d6956d386b "match: use '' instead of '.' for root directory",
'.' should be translated to ''. We can't blame repo.file() about this because
an empty string is invalid as a file path, but I found at least two callers
(_makematcher() and revset.filelog()) would crash because of this path[0].
So let's make repo.file() accept an empty string. path[0] == b'/' wouldn't
work on Python 3 anyways.
#require execbit
$ rm -rf a
$ hg init a
$ cd a
$ echo foo > foo
$ hg ci -qAm0
$ echo toremove > toremove
$ echo todelete > todelete
$ chmod +x foo toremove todelete
$ hg ci -qAm1
Test that local removed/deleted, remote removed works with flags
$ hg rm toremove
$ rm todelete
$ hg co -q 0
$ echo dirty > foo
$ hg up -c
abort: uncommitted changes
[20]
$ hg up -q
$ cat foo
dirty
$ hg st -A
M foo
C todelete
C toremove
Validate update of standalone execute bit change:
$ hg up -C 0
1 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ chmod -x foo
$ hg ci -m removeexec
nothing changed

$ hg up -C 0
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg up
3 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg st
$ cd ..
