rawdata: forward the method call on `filelog` object We have a new method, we need to expose it.

rawdata: introduce a `rawdata` method on revlog This method aims at replacing `revision(..., raw=True)` call. The purpose of data returned without and without raw are different enough that having two different method would make sense. This split is motivated by other work aiming at storing data on the side of the main revision of a revlog. Having a cleaner API makes it simpler to add this work. The series following this first changesets is organised as follow: 1) add `rawdata` method everywhere it is useful 2) update all caller 3) implement all `rawdata` method without using `revision` 4) deprecate the `rawdata` parameter of `revision`

revlog: split a `_revisiondata` method to file `revision` job We are about to introduce more public method to access revision data (eg: `rawdata`). revset subclass tend to recursively call `revision` which will create all kind of issue with the coming series. To avoid them we introduce an explicit difference between the internal call and the public all. This will be useful for later work anyway (so the subclass issue is just moving it earlier in the series). I am not sure if the subclass are actually doing something sensible. However, I am certain I don't want to be rabbit holed into figuring it out right now.

continue: added support for transplant This creates a seperate function `continuetransplant()` containing logic for resuming transplant from interrupted state. `continuetransplant()` is then registered as `continuefunc` for state detection API. Results are shown in tests. Differential Revision: https://phab.mercurial-scm.org/D6689

fncache: make debugrebuildfncache not fail on broken fncache The code reading the fncache changed in 5.0, to complain if the file is not \n terminated. This makes apparent the fact that the fncache gets corrupted. Make it possible to recover, instead of having `hg debugrebuildfncache` failing by saying `(run hg debugrebuildfncache)`. The corruption itself is most likely due to hg not using fsync in general, and so various bad things can happen. Here, the reported problems happened when running out of disk space. So I suspect that because the fncache is much bigger than the average commit/pull, when running out of disk space, the bulk of the pull may succeed, but the new fncache may get half-written and still renamed into place.

test: further fixes to matching for run-tests.py bug The fix in bac24a8a095a did not fix the full issue, because the extra number also eat some of the separator space. Since we are already matching arbitrary number of space, we easily fix the matching.

branchmap: explicitly warm+write all subsets of the branchmap caches 'full' claims it will warm all of the caches that are known about, but this was not the case - it did not actually warm the branchmap caches for subsets that we haven't requested, or for subsets that are still considered "valid". By explicitly writing them to disk, we can force the subsets for ex: "served" to be written ("immutable" and "base"), making it cheaper to calculate "served" the next time it needs to be updated.

changectx: extract explicit computechangesetfilesremoved method from context Right now, the logic around changeset centric removed files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

changectx: extract explicit computechangesetfilesadded method from context Right now, the logic around changeset centric added files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

demandimport: explicitly declare `_session` at the module level The `_session` module level variable is set within a function using the `global` keyword. This confuses my `test-check-pyflakes.t`. Explicitly declaring the variable at the top level solves the issue (and seems absolutely reasonable).

tests: give more room for slowness in test-run-tests.t The test expected any run-test.py run to end in less than 10 seconds. On slower loaded CI machine, this gets slower than that. We give a bit more room to the regexp.

copies: extract an explicit `computechangesetcopie` method from context Right now, the logic around changeset centric copies data are buried into the "changectx" code. We extract this code in a dedicated method (in the copies module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

config: fix fm.data() handling of defaultvalue This is a follow-up patch to rHG51a2e3102db2. This moves `fm.data()` out of the if block in `commands.config()`. Differential Revision: https://phab.mercurial-scm.org/D6720
