old remove code called localrepo.changes for each file.
was very expensive:
$ hg --time rm arch>/dev/null
Time: real 1066.120 secs (user 1014.450+0.000 sys 18.090+0.000)
new code, same files:
$ hg --time rm arch>/dev/null
Time: real 2.770 secs (user 2.190+0.000 sys 0.580+0.000)
also mention "-f" if not removing files. also allow "-f" to forget
added files.
make test a bit better.
(including small changes to revert and backout to not show these stats
with the exception of backout --merge)
Show update stats (unless -q), e.g.:
K files updated, L files merged, M files removed, N files unresolved
Inform the user what to do after a merge:
(branch merge, don't forget to commit)
Inform the user what to do if a branch merge failed:
There are unresolved merges, you can redo the full merge using:
hg update -C X
hg merge Y
Inform the user what to do if a working directory merge failed:
There are unresolved merges with locally modified files.
Some systems show "Thu Jan 01" instead of "Thu Jan 1", which breaks tests.
Using "1000000" yields "Mon Jan 12 13:46:40 1970", which looks the same on
all systems.
- this should allow better detection of removed file
when walking in the history (like hg log)
it doesn't help for the fast path of hg log where
we only look at the filelog
- users of the changelog file list shouldn't assume
anymore that the file still exist (anyway it won't
be found in the manifest like in 2e92bd60edac)
- fix the tests (some hashes changed)
