The bundled hg should work flawlessly in most cases. Make it depend on the external installation only if necessary since we can't control the whole environment. This patch doesn't implement the "exit 80" idea proposed by Jun. I don't want to keep the capability checking sync with the actual tests.

It's simple and works well unless you are using third-party extensions that changes the store format.

Since os.environ may be overridden in run-tests.py, several important variables such as PATH weren't restored. I don't like the idea of using the system hg *by default* because the executable and the configs are out of our control. But I don't mind as long as the tests pass.

This patch adds a `phabread` command generating plain-text patches from Phabricator, suitable for `hg import`. It respects `hg:meta` so user and date information might be preserved. And it removes `Summary:` field name which makes the commit message a bit tidier. To support stacked diffs, a `--stack` flag was added to read dependent patches recursively.

The `phabsend` command is intended to provide `hg email`-like experience - sending a stack, setup dependency information and do not amend existing changesets. It uses differential.createrawdiff and differential.revision.edit Conduit API to create or update a Differential Revision. Local tags like `D123` are written indicating certain changesets were sent to Phabricator. The `phabsend` command will use obsstore and tags information to decide whether to update or create Differential Revisions.

The default Phabricator client arcanist is not friendly to send a stack of changesets. It works better when a feature branch is reviewed as a single review unit. However, we want multiple revisions per feature branch. To be able to have an `hg email`-like UX to send and receive a stack of commits easily, it seems we have to re-invent things. This patch adds `phabricator.py` speaking Conduit API [1] in `contrib` as the first step. This may also be an option for people who don't want to run PHP. Config could be done in `hgrc` (instead of `arcrc` or `arcconfig`): [phabricator] # API token. Get it from https://phab.mercurial-scm.org/conduit/login/ token = cli-xxxxxxxxxxxxxxxxxxxxxxxxxxxx url = https://phab.mercurial-scm.org/ # callsign is used by the next patch callsign = HG This patch only adds a single command: `debugcallconduit` to keep the patch size small. To test it, having the above config, and run: $ hg debugcallconduit diffusion.repository.search <<EOF > {"constraints": {"callsigns": ["HG"]}} > EOF The result will be printed in prettified JSON format. [1]: Conduit APIs are listed at https://phab.mercurial-scm.org/conduit/

People often want to know what they are working on *now*. As part of this, they also commonly want to know how that work is related to other changesets in the repo so they can perform common actions like rebase, histedit, and merge. `hg show work` made headway into this space. However, it is geared towards a complete repo view as opposed to just the current line of work. If you have a lot of in-flight work or the repo has many heads, the output can be overwhelming. The closest thing Mercurial has to "show me the current thing I'm working on" that doesn't require custom revsets is `hg qseries`. And this requires MQ, which completely changes workflows and repository behavior and has horrible performance on large repos. But as sub-optimal as MQ is, it does some things right, such as expose a model of the repo that is easy for people to reason about. This simplicity is why I think a lot of people prefer to use MQ, despite its shortcomings. One common development workflow is to author a series of linear changesets, using bookmarks, branches, anonymous heads, or even topics (3rd party extension). I'll call this a "stack." You periodically rewrite history in place (using `hg histedit`) and reparent the stack against newer changesets (using `hg rebase`). This workflow can be difficult because there is no obvious way to quickly see the current "stack" nor its relation to other changesets. Figuring out arguments to `hg rebase` can be difficult and may require highlighting and pasting multiple changeset nodes to construct a command. The goal of this commit is to make stack based workflows simpler by exposing a view of the current stack and its relationship to other releant changesets, notably the parent of the base changeset in the stack and newer heads that the stack could be rebased or merged into. Introduced is the `hg show stack` view. Essentially, it finds all mutable changesets from the working directory revision in both directions, stopping at a merge or branch point. This limits the revisions to a DAG linear range. The stack is rendered as a concise list of changesets. Alongside the stack is a visualization of the DAG, similar to `hg log -G`. Newer public heads from the branch point of the stack are rendered above the stack. The presence of these heads helps people understand the DAG model and the relationship between the stack and changes made since the branch point of that stack. If the "rebase" command is available, a `hg rebase` command is printed for each head so a user can perform a simple copy and paste to perform a rebase. This view is alpha quality. There are tons of TODOs documented inline. But I think it is good enough for a first iteration.

Not only is the output of these commands inconsistent with respect to each other when a file is deleted, they are internally inconsistent depending upon whether the deleted file is in the top level repo or a subrepo. It seemed easier to show the problems, rather than describe them. The original goal was to fix the summary command with respect to deleted files. I haven't fixed any of the other issues yet, in case anybody believes the current subrepo behavior is correct. I think a natural understanding of clean/dirty is that they are two opposite values of a single binary repo state. If `hg update --clean -r .` changes a file, then naturally that repo was dirty, and `hg update --check` should have blocked it. Deleted files are special, in that they don't block a commit. But they make the filesystem content not the same as a clean checkout.

The ignore regular expression has been updated to detect "inconsistent config." If present, we track which configs have that set and we suppress the conflicting defaults error for those options. I also added named groups to the regexp to aid readability. A comment was added to profiling.py to make a desired inconsistent value error go away.

It isn't needed that storecache is derived from repofilecache. Changes in this patch allow repofilecache and storecache to do in own __init__() differently from each other.

This is a fix for my 14ad8e2a4abe, which used 'bool(dir)' as checkambig value for revlog.__init__(). I can't remember why I did so in 14ad8e2a4abe, but this is obviously wrong, because only root indexfile is cached via filecache-ed property of localrepository.

External hooks end up launching cmd.exe, which knows nothing about $VAR syntax. For some reason, I thought that Mercurial would substitute in the value, in order to paper over the platform difference. But I can't find that in the documentation, and there's at least one other use of this pattern [1]. [1] https://www.mercurial-scm.org/repo/hg/file/tip/tests/test-histedit-fold.t#l477

I've seen revlog._deltachain() appear in a number of performance profiles. I suspect there are 2 reasons for this: 1. Delta chain resolution performs many index lookups, thus triggering population of index tuples. Creating possibly tens of thousands of PyObject will have overhead. 2. Delta chain resolution is a tight loop. By moving delta chain resolution to C, we can defer instantiation of full index entry tuples and make the loop faster courtesy of not running in Python. We can measure the impact to delta chain resolution via `hg perflogrevision` using the mozilla-central repo with a recent manifest having delta chain length of 33726: $ hg perfrevlogrevision -m 364895 ! full ! wall 0.367585 comb 0.370000 user 0.340000 sys 0.030000 (best of 27) ! wall 0.357581 comb 0.360000 user 0.350000 sys 0.010000 (best of 28) ! deltachain ! wall 0.010644 comb 0.010000 user 0.010000 sys 0.000000 (best of 270) ! wall 0.000292 comb 0.000000 user 0.000000 sys 0.000000 (best of 8729) $ hg perfrevlogrevision --cache -m 364895 ! deltachain ! wall 0.003904 comb 0.000000 user 0.000000 sys 0.000000 (best of 712) ! wall 0.000284 comb 0.000000 user 0.000000 sys 0.000000 (best of 9926) The first test measures savings from both not instantiating index entries and moving to C. The second test (which doesn't clear the index caches) essentially isolates the benefits of moving from Python to C. It still shows a 13.7x speedup (versus 36.4x). And there are multiple milliseconds of savings within the critical path for resolving revision data. I think that justifies the existence of C code. A more striking example of the benefits of this change can be demonstrated by timing `hg debugdeltachain -m` for the mozilla-central repo: $ time hg debugdeltachain -m > /dev/null before: 1057.4s after: 503.3s PyPy2.7 5.8.0: 220.0s It's worth noting that the C code isn't as optimal as it could be. We're still instantiating a new PyObject for every revision. A future optimization would be to reuse the PyObject on the cached index tuple. We could potentially also get wins by using a memory array of raw integers. There is also room for a delta chain cache on revlog instances. Of course, the best optimization is to implement revlog reading outside of Python so Python doesn't need to be concerned about the relatively expensive index entries and operations on them.
