unshelve: don't commit unknown files during unshelve (
issue4113)
Previously, unshelve would temporarily commit unknown files (via addremove) in
an attempt to allow unshelving into unknown files. This produced unexpected
results, like the file time stamp changing and a .i file being created.
This change makes it no longer use addremove. It ignores unknown files
completely. If an unshelve would overwrite an unknown file, the unknown file is
moved to *.orig
The shelve continue/abort format is changed, but it just removes stuff from the
end of the file, so it can still read the old format.
$ hg init
$ echo This is file a1 > a
$ hg add a
$ hg commit -m "commit #0"
$ echo This is file b1 > b
$ hg add b
$ hg commit -m "commit #1"
$ hg update 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ echo This is file c1 > c
$ hg add c
$ hg commit -m "commit #2"
created new head
$ hg merge 1
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ rm b
$ echo This is file c22 > c
Test hg behaves when committing with a missing file added by a merge
$ hg commit -m "commit #3"
abort: cannot commit merge with missing files
