dirstate: use `reset_state` in `rebuild` instead of `dropfile` As `dirstatemap.dropfile` is on its way out. Differential Revision: https://phab.mercurial-scm.org/D11440

dirstate: use `reset_state` to drop file in `update_file_p1` The `dropfile` function is on its way out. Differential Revision: https://phab.mercurial-scm.org/D11439

dirstate: support file tracked nowhere in `reset_state` This let the dirstatemap decide when to drop files. Differential Revision: https://phab.mercurial-scm.org/D11438

dirstate: drop dirstatemap.addfile All users have been migrated. Differential Revision: https://phab.mercurial-scm.org/D11437

dirstate: update the documentation of the dirstatemap API The API changed so should the documentation. Differential Revision: https://phab.mercurial-scm.org/D11436

dirstate: drop the `_addpath` method All user have been migrated. Differential Revision: https://phab.mercurial-scm.org/D11435

dirstate: remove the `normallookup` function All use have been migrated. Differential Revision: https://phab.mercurial-scm.org/D11434

dirstate: stop using `_normallookup` in the adddrop extension That extension is just trying to produce a "corrupted" dirstate. Differential Revision: https://phab.mercurial-scm.org/D11433

dirstate: replace the use of `_normallookup` in `rebuild` Normal lookup is a complicated function that we want to get rid of. Differential Revision: https://phab.mercurial-scm.org/D11432

dirstate: replace the use of _normallookup in `setparents` normal lookup is a complicated function that we want to get rid of. Differential Revision: https://phab.mercurial-scm.org/D11431

dirstate: introduce a set_tracked method on "map" and "item" This move more implementation details withing the DirstateItem itself, which is what we have been doing for a while. Differential Revision: https://phab.mercurial-scm.org/D11430

dirstate: fix restoration of "merged" state after a remove Before this change, "merged" file that get removed and re-added later were recorded as "from_p2" instead. This came from 8fe74328f700, a 2014 changeset that start explicitly doing so for reason I have not been able to fully grasp. The graft test mentioned in the description are still happy after this changeset. So this changeset restore what seems to be the intended behavior. Restoring information as it was before the removal. Differential Revision: https://phab.mercurial-scm.org/D11429

dirstate: inline the last two `_drop` usage The function is small and having the associated code directly inline help use to cleanup the dirstate API. Differential Revision: https://phab.mercurial-scm.org/D11428

dirstate: make a conditionnal easier to read in `setparents` By grabing `nullid` in the local space, we get the conditionnal to fit in one line. Differential Revision: https://phab.mercurial-scm.org/D11427

dirstate: removed the now unused `_add` method Differential Revision: https://phab.mercurial-scm.org/D11426

dirstate: replace `_add` call in `setparent` Same logic as the previous changeset, it get us closer to removed older API on the dirstate. Differential Revision: https://phab.mercurial-scm.org/D11425

dirstate: directly call the right function in `set_tracked` This get use closer to removing some older API on the dirstate. Differential Revision: https://phab.mercurial-scm.org/D11424

dirstate: same logic as what we did for `_drop` This is part of the dirstatemap so let the dirstatemap deal with it. Differential Revision: https://phab.mercurial-scm.org/D11423

dirstate: use `tracked` property in `_addpath` It is semantically better. Differential Revision: https://phab.mercurial-scm.org/D11422

rust: Update the memmap2 crate to version 0.4.0 This version: * Optionally implements the `StableDeref` trait, removing the need for a wrapper type doing that * Adds support for mapping empty files, which can routinely happen for dirstate-v2 data files. This was a cause of some failing tests when running with `run-tests.py --rhg --extra-config-opt rhg.status=1` Differential Revision: https://phab.mercurial-scm.org/D11446

tests: make removeemptydirs more portable The behavior of pwd change from one system (i.e. default shell/sh) from one system to another so we use fuzzy matching for the output we do not care and we use narrower command call to highlight what we are trying to test here. Differential Revision: https://phab.mercurial-scm.org/D11449

check-code: make it possible to ignore the PWD check in some situation The check-code script does not motivate the banning of $PWD so I am not sure what it is about. And I will needs to use the env variable in the next tests. So I am adding a way to make an exception. Differential Revision: https://phab.mercurial-scm.org/D11450

dirstate: fix compilation warnings in `dirstate_item_set_possibly_dirty()` Since https://phab.mercurial-scm.org/D11387 (i.e. the same patch as mentioned in my previous patch), Clang has also started warning about `dirstate_item_set_possibly_dirty()` missing an explicit return, and about its use of the result of an assignment as a condition without using parentheses. This patch fixes that. Differential Revision: https://phab.mercurial-scm.org/D11445

dirstate: make dirstate flags char be unsigned Since https://phab.mercurial-scm.org/D11387, `CC='clang -Werror' make local` has started failing like this: ``` mercurial/cext/util.h:41:50: error: implicit conversion from 'int' to 'char' changes value from 128 to -128 [-Werror,-Wconstant-conversion] static const char dirstate_flag_rust_special = 1 << 7; ~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~^~~~ ``` This patch fixes that by making the flags be an unsigned char. That also matches the `bool` typedef we have in `util.h`, which seems good since many of the `dirstate_item_c_*()` functions return a `bool`. Differential Revision: https://phab.mercurial-scm.org/D11444

dirstate: introduce a `set_clean` method on dirstate's map and items This method is the "reverse" of "set possibly dirty", and can be used to more accurately other call that the dirstate was making. It is currently heavily influenced by its origin. Differential Revision: https://phab.mercurial-scm.org/D11421
