test-compat: merge mercurial-4.7 into mercurial-4.6

test-compat: merge stable into mercurial-4.7

compat: fix fixedcopytracing compatibility with mercurial 4.8 and narrow Mercurial 4.8 version of _fullcopytracing includes some new narrow code. As https://phab.mercurial-scm.org/D3896 has not yet landed, update fixedcopytracing behind a version detection condition. This was spotted by Augie Fackler.

utility: don't translate commit messages in revselection prompt (issue6016) Commit messages should not be translated and should be shown the same. I am not sure if I can add a test for this by creating a commit with non-ascii character in commit message.

evolve: use stack template in --continue case also We use stack indexes (s#) in evolve msging when revs being evolved are in active topic. Before this patch we are not covering the --continue case. So this patch cover the same and use the stack indexes s# even when we continue an interrupted evolve. In this patch I used the same concept (to check if we should use s#) as we are using in cases other than `--continue`. Thanks to PYD for refactoring those lines. Changes in tests also reflects the expected behaviour.

evolve: add test showing currently stackalias fails in --continue case

branching; merge with stable

packaging: mark version as devel version This avoid confusion from people installing from source.

evolve: do not try to display stack index of changeset who do not have one

evolve: check if we should use stack template for each item in the stack We should probably just track the current topic and move all the logic in the template itself. However, this is a good first step.

topic: add the changelog argument to branchinfo() 47c03042cd1d in core added a changelog argument to revbranchcache.branchinfo() and we wrap that function in topic extension. So let's add this optional argument in topic extension too.

evolve: adapt for changed @command decorator Core changed the hacky "^command" syntax to be a proper decorator option in fa88170c10bb (help: adding a proper declaration for shortlist/basic commands (API), 2018-10-12). This patch makes evolve compatible with that.

topicidx: stop assigning index number to obsolete changesets Obsolete changeset are no longer part of the stack, the old logic tried to assigns them the index of their successors but this is flacky and error prone. So we stop doing so.

stack-index: add some test featuring content diversion This will be useful to display various issues.

rewind: alias the command to undo This is a step in unifiying rewind and undo and not talk about them as different commands or concepts. If there exists rewind command, that should be an alias of undo and the vice versa. The exact implmentation detail and how the command works etc. is a different thing but there should be just one command.

changelog: add a line about the usage of s# in evolve

caches: no longer warm the cache on strip in "auto" mode Before this patch, a strip would trigger a full and blind cache load that would include the stablerange cache. In repository like Mozilla this was a bit painful. The default "auto" mode now behave has intended.

evolve: use stack alias s# in `hg evolve` msgs As repository grows revision number lose their usefulness. To make it a little better than now, after this patch we will be using short stack aliases introduced by the topic extension (as displayed by `hg stack`). These stack aliases s# will be used only when user has enabled topic extension and his repo's current active topic is same as the revs to be evolved. For now, this patch doesn't cover `continue` case. I will discuss about this with Pierre-Yves David. Maybe we have to store the info in evolvestate that "we were using stack aliases".

evolve: extract displayer to _solveone() I extracted this displayer method to _solveone() so that it would be easy to pass a different template to show evolve msgs. In upcoming patches we will be using stacktemplate in some cases where we want to include stack alias s# in evolve msgs.

utility: add a template alias that will be used in evolve msgs This template use stack alias s# instead of rev number in messages printed when we run `hg evolve`. For example, this template's msgs will look like this: move:[s3] add aaa atop:[s2] add bbb move:[s4] add ccc I will be using this template in upcoming patches.

topic: add topicidx template keyword This keyword will be useful where we want to see the index of the changeset in the stack when we run `hg stack`.

changelog: fix version number

tests: update the test-topic.t with changes in core mercurial Yuya stabilized the -T option and now it's in help by default. CORE-TEST-OUTPUT-UPDATE: 0d703063d0c8

pullbundle: fix style warning

pullbundle: improves management of multiple branch while dealing with a head There were still case where a range was issued too early.

pullbundle: deal with head in a predicable order We use node order to make this repeatable from one clone to another. This is an arbitrary pick.

pullbundle: deal with another special case introduced by arbitrary ranges previous, we dealt with the case where the tippest subrange of the stable parent was too long. Now, we need to deal with the case where it is too small.

pullbundle: compat with Mercurial 4.7

pullbundle: add some information on the cached change This also adds a way to skip "caching" smaller range in the debugcommand (not in the extensions itself).

pullbundle: add data about the cached bundle size and hit

pullbundle: add a command to generate cache hit statistic This new command should help checking that the stable range produce reusable bundle.

pullbundle: point out the output flooding issue from core Right now, we don't have a reliable progress report when using pullbundle.

pullbundle: issue local branches in the right order

pullbundle: delay cache file opening Otherwise we can end-up with a too many file open at the same time.

pullbundle: improve slicing of the lower part of range The previous method could get confuse by merge and overslice. The new method is better at using sticking on power of two boundaries.

stablerange: fix slicing of arbitrary ranges Pull bundle trigger slicing from range with arbitrary initial skip. We have to adjust the current slicing to take this into account.

pullbundle: attempt to save stablerange cache after each computation Since we do not serve the full repository, we use more stablerange starting from a random point. These are probably not loaded yet and should be cached. This is best effort caching, if we can't save them we won't.

pullbundle: add basic extension metadata

pullbundle: add a config option for the cache directory

pullbundle: add an output about the time spent slicing the set This will be useful to monitor overall performance.

pullbundle: add extension documentation

pullbundle: add an extra test showing how cache are reusable We issue a single final pull, most of its item are reusable.

pullbundle: add caching logic We now only generate a bundle once (and store it to disk). If we need it again, we use it directly from disk.

pullbundle: slice pull into multiple ranges We subdivide the set of missing revisions into multiple "range" using the "stable range" data structure. This slicing aims at maximizing the capability of the resulting ranges.

pullbundle: initial commit Right now, we do not do any slicing, but we install the wrapping and the tests.

topic: respect preexisting 'topic' value on workingcommitctx Mercurial's core changeset: 6c8ceebce309 revealed an issue. If the creator of a workingcommitctx explicitly assigned a 'topic', it was silently overridden by the current active on. This break import of patch with topic information. We now respect preexisting topic information.

topic: add a compatibility to access transaction's names The attribute was made private in 4024c363cd33.

topic: add a compatibility to access transaction's validator The attribute was made private in ebbba3ba3f66.

evovle: remove redundancy in evolve output Copying the discription of this redundancy issue given by Pierre Yves David: When running `hg evolve` to stabilize orphan changeset output about the currently stabilized changeset is issued. For example: $ hg evolve move:[3] a3 atop:[4] a2 working directory is now at 7c5649f73d11 This output can become quite repetitive when orphan are stabilized atop each other. For example: $ hg evolve --all move:[8] dansk 2! atop:[10] dansk! merging main-file-1 move:[9] dansk 3! atop:[11] dansk 2! In this case it would be smoother to issue: $ hg evolve --all move:[8] dansk 2! atop:[10] dansk! merging main-file-1 move:[9] dansk 3! Since we are moving "dansk 3!" atop the changeset we just stabilized. When adding this be careful that we still want to issue the "atop" message in various cases: 1. first changesets in a stack 2. when the orphan is not stabilized atop previous one 3. when using hg evolve --continue to resume an evolution So, I have made the changes which also respect above listed three points. And changes in tests/test-evovle*.t reflecting the changed behavior.

amend: handle crash before transaction initialization with --patch The `tr` object can be None.

obsdiscovery: adopt to calling convention change Upstream commits 71d83b315778 and abce899c985f changed the calling convention of setdiscovery._takefullsample(). We inspect the signature of the function before calling it so we can pass the proper arguments.

caches: issue both debug and blackbox log message This increase the odd someone looking for issue will find them.

cmdrewrite: rename variable and move it closer to where it is used Renaming to satisfy pep8-naming linter plugin, which complained on this variable because all-uppercase names are reserved for constants, and constants need to be module-level. This variable is not a good choice for moving up to the module level because it's used only in one place. Additionally, let's have it closer to the place it's actually used to potentially avoid an extra call to _() function (however cheap it may be).

changelog: mention the cache improvements

obshashrangecache: be more paranoid in the errors we catch It seems like there error were already covered. Better safe than sorry.
