dirstate: perform transactions with _copymap using single call, where possible This replaces patterns such as this: ``` if f in self._copymap: del self._copymap[f] ``` with this: ``` self._copymap.pop(f, None) ``` Although eliminating the extra lookup/call may be a negligible performance win in the standard dirstate, alternative implementations, such as [sqldirstate](https://bitbucket.org/facebook/hg-experimental/src/default/sqldirstate/) may see a bigger win where each of these calls results in an RPC, so the savings is greater.

pull: do not prompt "hg update" if update.requiredest is set Previously, after pull, we show: (run 'hg update' to get a working copy) unconditionally. People might run `hg update` and get an exception if `update.requiredest` is set, and get a bit frustrated. This patch changes the code to not prompt `hg update` in that case.

changelog: abort on attempt to write wdir revision Similar to the previous patch which prevented writing the null revision to any revlog, but this is for the wdir revision. Thanks to Jun for pointing this out. Differential Revision: https://phab.mercurial-scm.org/D524

phabsend: show associated Differential Revisions with --confirm Often people running `phabsend --confirm` just want to check whether a commit will trigger a creation of new Differential Revision, or update an existing one. This patch implements that. The `--confirm` message was changed to use node instead of revision number to be consistent with what `phabsend` outputs. An example output looks like: D487 - a80f447973a0 test-extension: enable demandimport explicitly D494 - cf440ea6e47e test-casecollision-merge: fix the test NEW - 0a6b97147128 phabsend: polish the docstring a bit Send the above changes to https://phab.mercurial-scm.org/ (yn)?

phabsend: print the actual URL with --confirm Sometimes people have multiple Phabricator endpoints set in multiple repos. It seems better for `--confirm` to prompt about the Phabricator endpoint patches being sent to. Differential Revision: https://phab.mercurial-scm.org/D513

phabsend: detect patch change with larger context Previously phabsend has an optimization that will skip uploading a diff if the patch (with context line number = 1) remains unchanged. That could be confusing: Aug 24 15:52:28 <martinvonz> phillco: something is wrong with phabricator'your patches/ Aug 24 15:52:45 <martinvonz> ... with phabricator's view of your patches again Aug 24 15:53:38 <martinvonz> if i phabread D388 and then D399, i get a version of filemerge.py with "a, b, c" somewhere on line 344, which is not what phabricator shows for D399 Aug 24 15:53:51 <martinvonz> junw: maybe that's more for you ^ Fix that by checking context with 32767 lines, which is the same as what will be actually sent.

phabsend: make --amend the default The local tag feature was intended to make `phabsend` closer to `email` workflow. But its experience is not great in multiple ways: - after rebase, obsoleted changesets are still visible because of tags - without obsstore, the association information will get lost - even with obsstore, things could go wrong with graft, export+import - no easy way to tell which Differential Revision a commit is associated Therefore make `--amend` the default. People wanting the old behavior can use `--no-amend`. Differential Revision: https://phab.mercurial-scm.org/D511

record: make the m key open an editor for the commit message (issue5667) With the former crecord extension, the user could edit the commit message while he was de-/selecting hunks. By pressing 'm', an editor showed up to edit the commit message. With record being part of mercurial, this feature is not available anymore. However, the help text still mentions it. As the infrastructure needed is still present, this feature is quite easily ported from the crecord extension to mercurial. It seems there is no test coverage for record ui, so I tested this patch manually on my local machine.

releasenotes: view admonition titles using -l flag Since this extension is fairly new for almost all the contributors, remembering the admonition (with titles) is difficult. The list (-l) flag provides a list of all the active admonitions along with titles. For usage, hg releasenotes -l returns the list. Differential Revision: https://phab.mercurial-scm.org/D454

tests: move baduisetup test inside "#if demandimport" The test case depends on the failure happening not at import time, but at uisetup() time, so it doesn't make sense when demandimport is disabled. There was already a section for testing demandimport stuff, so I moved it inside that existing section. As part of the move, I enabled the extension using '--config' so subsequent tests don't get the bad extension enabled. Differential Revision: https://phab.mercurial-scm.org/D526

revlog: abort on attempt to write null revision My repo got corrupted yesterday by something that ended up writing the null revision to the revlog (nullid hash, not nullrev index, of course). We use many extensions internally (narrowhg, remotefilelog, evolve, internal extensions) and treemanifests are on. The null revision was written to the changelog, the root manifest log, and one subdirectory manifest log. I have no idea exactly why the null revision was written, but it seems cheap enough to check that we should fail instead of corrupting the repo.

context: remove unnecessary default values for matchers (API) ctx._dirstatestatus() is called only from workingctx._buildstatus() and that function, in turn, is called only from basectx.status(). basectx.status() will always pass a matcher to _buildstatus(), so there's no need to handle a None matcher there. Differential Revision: https://phab.mercurial-scm.org/D492

run-tests: make per-line condition support testcase names 7340465bd added multiple test cases support. The latter has a problem - output lines cannot be made conditional with `#if`: ``` # COUNTEREXAMPLE: DOES NOT WORK #testcases A B $ command-foo common ouput #if A A's ouput #else B's ouput #endif common ouput ``` That's not trivial to fix (even if it works in test, `run-tests.py -i` may be suboptimal because diff algorithm does not know how to skip the `#if` lines, even if it does, it may have trouble figuring out whether a changed line belongs to inside a `#if` block or outside). Matching output lines conditionally is useful. 4eec2f04a added per-line condition support for hghave. This patch extends that to also support test case names.
