cmdutil.jsonchangeset: properly compute added and removed files
jsonchangeset._show() was computing the reverse status of the current
changeset. As a result, added files were showing up as removed and
removed files were showing up as adds.
There were existing tests for this code and they were flat out wrong.
rebase: clarify comment about merge ancestor when rebasing merges
The code for picking a merge ancestor when rebasing merges had a long and
incorrect comment.
The comment would perhaps have been fine as commit message but does
not make the code more readable or maintainable and is a bad
substitute for correct and readable code.
The correct essense of the comment is quite trivial: a merge of an ancestor of
the rebase destination and an 'outside' revision can be rebased as if it was a
linear change, using 'destination ancestor parent' as base and pretty much
ignoring the 'outside' revision.
The code path where the comment is placed is however also used for other kinds
of merge rebases. The comment is thus not really correct and not helpful. I
think it would be better to drop the comment and rewrite the code.
status: don't list files as both clean and deleted
Tracked files that are deleted should always be reported as such, no
matter what their state was in earlier revisions. This is encoded in
in two conditions in the loop in basectx._buildstatus() for modified
and added files, but the check is missing for clean files. We should
check for clean files too, but instead of adding the check in a third
place, move it earlier and skip most of the loop body for deleted
files.
status: don't list files as both removed and deleted
When calculating status involving the working copy and a revision
other than the parent of the working copy, the files that are not in
the working context manifest ('mf2' in the basectx._buildstatus())
will be reported as removed (note that deleted files _are_ in the
working context manifest). However, if the file is reported as deleted
in the dirstate, it will get that status too (as shown by failing
tests).
Fix by removing deleted files from the 'removed' list after the main
loop in _buildstatus().
revset-filelog: handle hidden linkrev for file missing for head (
issue4490)
The fix for linkrev pointing to hidden revision was crashing when the file was
missing from head's manifest. We now properly handle this case.
(yes I feel silly)
run-tests: automatically add (glob) to "saved backup bundle to" lines
Avoid spending too much time adding (glob) after running run-tests -i. This
doesn't handle all cases but it helps.
The run-tests tests add a bit of escaping of trailing (glob) in the output to
avoid interference from the outer test runner.
The regexp for matching the output lines contains a group for making multiline
substitute in a way that works with Python before 2.7.
