The merge tool configuration in general has always been a confusing topic for
user. We add mention of:
- possible pre-existing configuration,
- way to look at it,
- the more detailed help topic about how merge-tools configuration works.
This should help users find they way.
We were always using only the first 12 characters of the subrepo revision id
when generating the "subrepo diverged" promptchoice. This is not necessarily
correct for non mercurial subrepos.
This method takes an "id" (e.g. a revision id) and returns a "short" version
(e.g. a short revision id).
This will be used on the next revision to fix a small bug in the way that the
text on the promptchoice shown when a subrepo diverges is generated.
This patch is a step forward in getting rid of needing to check 'parentworking'
throughout the status method. Eventually, we will use the power of inheritance
to do the correct thing when comparing the working directory with its parent.
This method is mostly a copy from localrepo.status. The custom status method of
workingctx will eventually be absorbed by the refactoring of localrepo.status
to context.status but unfortunately we can't do it in one step.
The old code had one function that could do 2 different things. First,
is was called a bunch of times to do one thing. Next, it was called a
bunch of times to do the other thing. That gave unnecessary complexity
and a dispatch overhead. Having separate functions is "obviously" better
than having a function that can do two things, depending on its parameters.
It also prepares the code for the next refactorings.
Preparing for action list split-up, making sure the final change don't have any
test changes.
The patch moves debug statements around without really changing anything.
Arguably, it temporarily makes the code worse. The only justification is that
it makes it easier to review the test changes ... and in the end the big change
will not change test output at all.
The changes to test output are due to changes in the ordering of debug output.
That is mainly because we now do the debug logging for files when we actually
process them. Files are also processed in a slightly different but still
correct order. It is now primarily ordered by action type, secondarily by
filename.
The patch introduces some redundancy. Some of it will be removed again, some of
it will in the end help code readability and efficiency. It is possible that we
later on could introduce a "process this action list and do some logging and
progress reporting and apply this function".
The "preserving X for resolve" debug statements will only have single space
indentation. It will no longer have a leading single space indented "f: msg ->
m" message. Having this message double indented would thus no longer make
sense.
The bid actions will temporarily be sorted using a custom sort key that happens
to match the sort order the simplified code will have in the end.
The ordering of actions matters. Normal file system semantics is that files
have to be removed before a directory with the same name can be created.
Before the first ordering key was to have 'r' and 'f' actions come first,
secondary key was the filename.
Because of future refactorings we want to consistently have all action types
(with a sensible priority) as separate first keys. Grouped by action type, we
sort by filename.
Not processing in strict filename order could give worse performance,
especially on spinning disks. That is however primarily an issue in the cases
where "all" actions are of the same kind and will be grouped together anyway.
One must choose between ``"y yes".split()`` and ``('y', 'yes')``. I choose the
later.
The feature still crash when you answer "yes" to use it. But at least, the
prompt itself works.
The `--interactive` flag workis by overwriting the original test file by its
`.err` version. So we need to write it before calling `self.fail`. Otherwise the
`.err` file does not exists and `--interactive` is ignored.
We can move that block code around because it is dedicated to write changed
output and we moves it in the try-except dedicated to handling changed output.
Note that the flog is still badly broken after this change. But at least it crash
instead of being ignored.
