largefiles: introduce push --lfrev to control which revisions are pushed
The default of pushing all largefiles referenced in outgoing revisions is safe,
but also expensive and sometimes not what is needed. We thus introduce a
--lfrev option, similar to what pull already has.
By specifying an empty set of revisions (or null), it is possible to get lazy
(and insecure!) pushes of revisions without referenced largefiles, similar to
how pull works.
$ 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
