We perform all that we can non-interactively before prompting the user for input
via their merge tool. This allows for a maximally consistent state when the user
is first prompted.
The test output changes indicate the actual behavior change happening.
The current output for a failed merge with conflict markers looks something like:
merging foo
warning: conflicts during merge.
merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
merging bar
warning: conflicts during merge.
merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')
We're going to change the way merges are done to perform all premerges before
all merges, so that the output above would look like:
merging foo
merging bar
warning: conflicts during merge.
merging foo incomplete! (edit conflicts, then use 'hg resolve --mark')
warning: conflicts during merge.
merging bar incomplete! (edit conflicts, then use 'hg resolve --mark')
The 'warning: conflicts during merge' line has no context, so is pretty
confusing.
This patch will change the future output to:
merging foo
merging bar
warning: conflicts while merging foo! (edit, then use 'hg resolve --mark')
warning: conflicts while merging bar! (edit, then use 'hg resolve --mark')
The hint on how to resolve the conflicts makes this a bit unwieldy, but solving
that is tricky because we already hint that people run 'hg resolve' to retry
unresolved merges. The 'hg resolve --mark' mostly applies to conflict marker
based resolution.
With this change resolve and revert produce consistent output when run with no
arguments:
$ hg resolve
abort: no files or directories specified
(use --all to remerge all files)
$ hg revert
abort: no files or directories specified
(use --all to revert all files)
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
Without specifying the parent revision of the working copy, users will
update to tip, which is most likely the other head they were trying to
merge, not the revision they were at before the merge.
