rust: look up HgRevlogIndex_GetParents() from symbol table And removes the unused index_get_parents_checked() function. I expect the Index struct will be turned into a pyobject type, though I haven't written any PoC-level patches yet.

revlog: add public CPython function to get parent revisions Since this is a public function, it validates the input revision, and supports nullrev. index_get_parents_checked() will be replaced by this function.

revlog: rename indexType to HgRevlogIndex_Type as it's a global symbol It follows the CPython naming convention, but uses Hg instead of Py.

revlog: export symbol of indexType The idea is to wrap the index object with rust-cpython. I haven't tried it, but it should be doable. We'll probably need a better interface than raw function pointers to do more in Rust.

setup: fix path of rust source dependencies Appears that they were screwed up while moving the source files around. Since rust-direct-ffi sources are automatically added to the depends list, we only need to list hg-core sources.

rebase: remove now-unnecessary arguments to _abort() Since _abort() is now an instance method, we don't need to pass state that's available on "self". Differential Revision: https://phab.mercurial-scm.org/D5393

rebase: move abort() onto rebaseruntime The function depends on a lot of the state of rebaseruntime, so it makes sense for it to be an instance method. This will let us remove many of the arguments to the method. That will be done in a later patch. Differential Revision: https://phab.mercurial-scm.org/D5392

cleanupnodes: trust caller when "moves" is not None If "moves" (indicating how to move bookmarks) is None, we fill it out based on "replacements" (indicating which obsmarkers to add). If "moves" is not None, we would still add items based on "replacements". This makes it impossible to pass "moves={}" and not move bookmarks, which surprised me. The only caller that currently passes a value for "moves" was the rebase extension and there we were already adding bookmark moves corresponding to obsmarker additions, so it should not be impacted.

shelve: change transaction description from "commit" to "shelve" "commit" was probably a copy&paste mistake. Differential Revision: https://phab.mercurial-scm.org/D5390

shelve: drop unnecessary backup of dirstate for phase-based case Regular shelve has a hack using an uncommitted transaction that's then aborted at the end of the operation. It preserves the dirstate across the abort, however, by saving a backup copy of it. Phase-based shelve instead commits the transaction, so the hack shouldn't be necessary there.

tests: split test-shelve.t in two test-shelve.t dominated run time for all shelve tests.

remotefilelog: rely on progress helper for keeping track of position The progress helper class keeps track of its current position, so we don't need a "count" variable for that. Differential Revision: https://phab.mercurial-scm.org/D5386

remotefilelog: reduce use of "count" container We had already given the initial value of "count[0]" a name, so just use that when applicable. Differential Revision: https://phab.mercurial-scm.org/D5385

remotefilelog: replace a "a=[expr]; b=a[0]" by "b=expr; a = [b]" Simpler is better. Differential Revision: https://phab.mercurial-scm.org/D5384

remotefilelog: remove an unnecessary update of "count" container The "count" container is never used after this point, so there is no need to update it. Differential Revision: https://phab.mercurial-scm.org/D5383

remotefilelog: avoid temporarily using "count" variable as synonym for "total" The "count" variable is generally used for updating progress, but early in fileserverclient.request(), its used to mean the total count. We already have another "total" variable for that, so it seems much clearer to use that. Differential Revision: https://phab.mercurial-scm.org/D5382
