dirstate-v2: Move data file info in the docket closer together Having `data_size` next to `uuid_size` (and the UUID itself) makes more sense. Differential Revision: https://phab.mercurial-scm.org/D11545

dirstate-item: drop the legacy new_normal constructor Nobody is calling it anymore. Its purposes has been filled. Differential Revision: https://phab.mercurial-scm.org/D11608

dirstate-item: replace call to new_normal The constructor is on its way out, so we inline the last relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11607

dirstate-item: replace a call to new_normal The constructor is on its way out, so we inline a relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11606

dirstate-item: drop the legacy new_possibly_dirty constructor Nobody is calling it anymore. Its purposes has been filled. Differential Revision: https://phab.mercurial-scm.org/D11605

dirstate-item: replace call to new_possibly_dirty The constructor is on its way out, so we inline the last relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11604

dirstate-item: drop the legacy new_from_p2 constructor Nobody is calling it anymore. Its purposes has been filled. Differential Revision: https://phab.mercurial-scm.org/D11603

dirstate-item: replace call to new_from_p2 The constructor is on its way out, so we inline the last relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11602

dirstate-item: drop the legacy new_added constructor Nobody is calling it anymore. Its purposes has been filled. Differential Revision: https://phab.mercurial-scm.org/D11601

dirstate-item: replace call to new_added The constructor is on its way out, so we inline the last relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11600

dirstate-item: drop the legacy new_merged constructor Nobody is calling it anymore. Its purposes has been filled. Differential Revision: https://phab.mercurial-scm.org/D11599

dirstate-item: replace call to new_merged The constructor is on its way out, so we inline the last relevant call before dropping it. Differential Revision: https://phab.mercurial-scm.org/D11598

dirstate-item: drop the `merged` property It has no user anymore. Differential Revision: https://phab.mercurial-scm.org/D11597

dirstate-item: replace another usage of `merged` We simply spell out the logic here. This was the last usage of `merged`. Differential Revision: https://phab.mercurial-scm.org/D11596

dirstate-item: replace a `merged` usage with `p2_info` It seems more accurate and no test complains (XXX hopefully XXX). Differential Revision: https://phab.mercurial-scm.org/D11595

dirstate-item: drop the `from_p2` property It has no user anymore. Differential Revision: https://phab.mercurial-scm.org/D11594

dirstate-item: directly use `p2_info` in `v1_size` This is simpler. Differential Revision: https://phab.mercurial-scm.org/D11593

dirstate-item: use the `p2_info` property to replace more verbose call Differential Revision: https://phab.mercurial-scm.org/D11592

status: process `from_p2` file the same as `merged` one What matters here is that the file constains information coming from the second parent and should be considered `modified` on plain `hg status. So we can process `from_p2` file sooner. It also highlight that we probably don't need the merged/from_p2 distinction at higher level. Differential Revision: https://phab.mercurial-scm.org/D11591

dirstate: drop an incorrect comment We are actually checking that we are only in a case were the file might needs lookup before doing this. So the comment is not relevant. Differential Revision: https://phab.mercurial-scm.org/D11590

dirstate: drop some duplicated code The same operation is done a handful a line lower. Differential Revision: https://phab.mercurial-scm.org/D11589

dirstate: align the dirstate's API to the lower level ones This conclude the refactoring of this API. We can now finalize the dirstate v2 on disk format. Differential Revision: https://phab.mercurial-scm.org/D11587

dirstate-item: introduce a `p1_tracked` property It is useful to simplify various conditional that use `any_tracked and not added`. Differential Revision: https://phab.mercurial-scm.org/D11586

dirstate-item: introduce a `p2_info` property that combine two others The `merged` and `from_p2` property are always used together so we can expose a combined property instead. Differential Revision: https://phab.mercurial-scm.org/D11585

dirstate: narrow gathering of parent data The parent data are only going to be useful is the file might be clean. And it might only be clean if it is tracked in both p1 and the working copy. Differential Revision: https://phab.mercurial-scm.org/D11584

dirstate: align the dirstatemap's API to the data change We are passing different data, so lets simplify the dirstatemap API too. Differential Revision: https://phab.mercurial-scm.org/D11583

dirstate-v2: Store a bitfield on disk instead of v1-like state Differential Revision: https://phab.mercurial-scm.org/D11558

dirstate-item: change the internal storage and constructor value This should be closer to what we do need and what we can actually reliably record. In practice it means that we abandon the prospect of storing much more refined data for now. We don't have the necessary information nor code using it right now. So it seems safer to just use a clearer version of what we had so far. See the documentation changes for details. Differential Revision: https://phab.mercurial-scm.org/D11557

dirstatemap: drop legacy method on the dirstatemap wrapper They are no longer in use now that the Rust wrapper version of the Dirstatemap are back in line with the Python one. Differential Revision: https://phab.mercurial-scm.org/D11582

dirstatemap: align the Rust wrapper implementation of `setparent` We move to using `drop_merge_data` as intended. Differential Revision: https://phab.mercurial-scm.org/D11581
