rebase: rewrite _computeobsoletenotrebased The old code stores successors of all related nodes together, which works fine if destination is unique. A future patch would make destination non-unique so let's change the implementation to test successors for rebaseset separately. Differential Revision: https://phab.mercurial-scm.org/D347

util: use ~ as a suffix for a temp file in the same directory as a source file Tools like Buck have patterns to ignore the creation of files (in the working copy) that match certain patterns: https://github.com/facebook/buck/blob/39278a4f0701c5239eae148968dc1ed4cc8661f7/src/com/facebook/buck/cli/Main.java#L259-L299 When Buck sees a new source file (as reported by Watchman), it has to invalidate a number of caches associated with the directory that contains the file. Using a standard suffix, such as `~`, would make it easier for Buck and others to filter out these types of file creation events. The other uses of `tempfile.mkstemp()` in Hg do not appear to be problematic because they (generally speaking) do not specify the `dir` parameter, so the new file is created in the system-appropriate temp directory, which is outside the working copy.

tests: rename test-terse-status.t to test-status-terse.t When looking for status tests, most people would probably look for "test-status*", so it would be nice if they could find it there. This also let's them run (most) status tests with "run-tests.py test-status*". Differential Revision: https://phab.mercurial-scm.org/D547

metadataonlyctx: don't crash when reusing the manifest with deletions This was originally fixed by Mateusz Kwapich for the `metaedit` command in fb-hgext with a test for the `metaedit` command. It didn't get upstreamed because `metaedit` was not in core. This patch fixes the crash and adds a test about `metadataonlyctx` to avoid future regressions. Differential Revision: https://phab.mercurial-scm.org/D550

context: make parents and text optional in metadataonlyctx The metadataonlyctx is to copy an existing context with some minor metadata changes. If the caller only wants to change "extra", or "user", ideally it does not have to read and pass "parents" and "text" information. This patch makes "parents" and "text" optionally to convenient callers. Differential Revision: https://phab.mercurial-scm.org/D548

test: add more obsmarker tests for pruning scenarios The obsfate output in cases of pruning is not ideal right now, add some tests so have these scenarios around.

template: better prune support in obsfate successorssets don't returns good results for pruned commit, add a workaround for simple cases. A proper fix would require a large rework of successorssets algorithm, I will send a separate series for this refactoring.

template: compute dates in obsfatedate Extract the dates from obsmarkers. Compute the min and max date from the obsmarker range list.

template: compute user in obsfateusers Extract, deduplicate users informations from obs markers in order to display them. Print all users for the moment, we might want to display users only in verbose mode later.

template: compute verb in obsfateverb Add a template function obsfateverb which use the markers information to compute a better obsfate verb. The current logic behind the obsfate verb is simple for the moment: - If the successorsets is empty, the changeset has been pruned, for example: Obsfate: pruned - If the successorsets length is 1, the changeset has been rewritten without divergence, for example: Obsfate: rewritten as 2:337fec4d2edc, 3:f257fde29c7a - If the successorsets length is more than 1, the changeset has diverged, for example: Obsfate: split as 2:337fec4d2edc, 3:f257fde29c7a As the divergence might occurs on a subset of successors, we might see some successors twice: Obsfate: split as 9:0b997eb7ceee, 5:dd800401bd8c, 10:eceed8f98ffc; split as 8:b18bc8331526, 5:dd800401bd8c, 10:eceed8f98ffc

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.

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.
