obsolete: _rename encodemeta to _fm0encodemeta This will be format zero specific.

obsolete: store metadata as a tuple of (key, value) pairs (API) Different formats will encode metadata in different ways. So we cannot keep the binary blob in the object anymore. We use a tuple to ensure it is immutable and hashable.

templater: fix ifcontains when list is a string (issue4399)

shelve: don't delete "." when rebase is a no-op (issue4398) When unshelving and facing a conflict, if we resolve all conflicts in favour of the committed changes instead of the shelved changes, then the ensuing implicit rebase is a no-op. That is, there is nothing to rebase. In this case, there are no extra intermediate shelve commits to strip either. Prior to this change, the commit being unshelved to would be marked for destruction in a rather catastrophic way. The relevant part of the test case failed as follows: $ hg unshelve -c unshelve of 'default' complete $ hg diff warning: ignoring unknown working parent 33f7f61e6c5e! diff --git a/a/a b/a/a new file mode 100644 --- /dev/null b/a/a @@ -0,0 1,3 @@ a c x $ hg status warning: ignoring unknown working parent 33f7f61e6c5e!

merge: make error message consistent with other commands If a merge is attempted when another merge is already ongoing, we give the message "outstanding uncommitted merges". Many other commands (such as backout, rebase, histedit) give the same message in singular form. Since the singular form also seems to make more sense, let's use that for 'hg merge' as well.

test-run-tests: add a test for detection of failure to start a server This also highlights a bug: right now we print "2 failed" but we only ran one test.

run-tests: more accurate/helpful message than "diff generation failed" Diff generation didn't really fail, it recognized that an hg serve server has failed to start, and thus skipped the diff generation intentionally. The most common reason for a server to fail to start is that the port was already in use, so output HGPORT as well, to help finding it (since pgrep -f 'hg serve' is not sufficient, if the command line is something like 'hg -R main serve')

run-tests: handle --jobs and --first gracefully Without this change, --first causes currently-running tests to explode in violent and surprising ways when their temporary directory gets cleaned up. Now we just suppress failure messages from non-first failures when running in --first mode.

config: use the same hgrc for a cloned repo as for an uninitted repo This just copies the same local sample hgrc, except it sets the default path to the repo it was cloned from. This is cut-and-paste from the local sample hgrc, but I think it's acceptable, since the two pieces of code are right next to each other and they're small. There is danger of them going out of synch, but it would complicate the code too much to get rid of this C&P. I also add ui as an import to hg.py, but with demandimport, this should not be a noticeable performance hit.
