fix: correct the clang-format example hgrc so that it actually works There are three changes here: * Remove -i from `command`, it causes fix to eat your file and empty it out * Add `set:` to pattern, otherwise this is interpreted as just a glob * Switch `listfile:` to `include:`; `listfile:` is relative to the current working directory, while `include:` is relative to the repo root. This makes it so that you don't receive errors when running outside of the repo root about being unable to find the file. Differential Revision: https://phab.mercurial-scm.org/D7618

rust-core: extracted a revlog submodule This moves fundamental definitions from the top of the crate to the newly created `revlog` submodule and reexports them for easy compatibility. As we are about to add new features to this crate, we felt it will improve clarity, and moreso if `ancestors` and `dagops` would become submodules of `revlog`.

remotefilelog: actually fix (and test this time) a bytes vs str issue I attempted this in 94670e124d29 but we didn't actually have any tests for this function it seems, and I mistook "it works now" for it being fixed (when what had actually happened was that my cache had populated enough that I didn't trigger the minimum threshold on my reattempts).

zstandard: vendor python-zstandard 0.13.0 Version 0.13.0 of the package was just released. It contains an upgraded zstd C library which can result in some performance wins, official support for Python 3.8, and a blackened code base. There were no meaningful code or functionality changes in this release of python-zstandard: just reformatting and an upgraded zstd library version. So the diff seems much larger than what it is. Files were added without modifications. The clang-format-ignorelist file was updated to reflect a new header file in the zstd distribution. # no-check-commit because 3rd party code has different style guidelines Differential Revision: https://phab.mercurial-scm.org/D7770

match: don't util.normpath() cwd The problem here is that `util.normpath()` calls `util.pconvert()`, which switches to Unix style separators. That results in two test failures like this since 5685ce2ea3bf: --- c:/Users/Matt/hg/tests/test-globalopts.t +++ c:/Users/Matt/hg/tests/test-globalopts.t.err @@ -89,7 +89,7 @@ [255] $ hg -R b ann a/a abort: a/a not under root '$TESTTMP/b' - (consider using '--cwd b') + (consider using '--cwd ..\$TESTTMP\b') [255] $ hg log abort: no repository found in '$TESTTMP' (.hg not found)!

commitablectx: fix the default phase The code was ignoring the config option. Since the config option will control the actual phase of the committed result, we better take it in account early. Differential Revision: https://phab.mercurial-scm.org/D7726

fix: fix handling of merge commits by using overlayworkingctx Most of this code was conceptually copied from what rebase does, with one small difference: hgext.rebaserev.rebase uses branchmerge=True, while I had to use branchmerge=False, or else it got really confused about updating to the same revision in some situations. I believe that the difference is that rebase is always dealing with *some* form of update - it never gets to mergemod.update if the source and destination are the same, while we can encounter that situation with fix. This may imply that this code has some issues with named branches that should be investigated. Differential Revision: https://phab.mercurial-scm.org/D7703

rust-index: add a struct wrapping the C index Implementing the full index logic in one go is journey larger than we would like. To achieve a smoother transition, we start with a simple Rust wrapper that delegates allwork to the current C implementation. Once we will have a fully working index object in Rust, we can easily start using more and more Rust Code with it. The object in this patch is functional and tested. However, multiple of the currently existing rust (in the `hg-cpython` crate) requires a `Graph`. Right now we build this `Graph` (as cindex::Index) using the C index passed as a PyObject. They will have to be updated to be made compatible. Differential Revision: https://phab.mercurial-scm.org/D7655

rust-index: add a `inner` method to the Index struct We are about to introduce a Rust wrapper to the C index. It will be exposed as a Python object. As a start all call will be forwarded to an internal index object (as used now). For this forwarding to works, we need to access that index object (from the C extensions). We adds a method doing to on the existing `Index` rust struct. Differential Revision: https://phab.mercurial-scm.org/D7654

revlog: made C Capsule an array of function pointers Although it's perfectly valid to put a function pointer in a capsule, as we've been doing since the start of rust/hg-cpython, an array of function pointers has several advantages: - it can hold several functions. That's our main motivation here. We plan to expose index_length() and index_node(), which will be needed for a Rust implementation of nodemap. - it could also have data - (probably minor in the case of Mercurial) proper support for architectures for which data and code pointers don't have the same size. Differential Revision: https://phab.mercurial-scm.org/D7543

lfs: fix a discrepancy with a function wanting a filelog, but calling it rlog This conceptually broke in 1541e1a8e87d when the filelog isa revlog relationship was changed to containment of the revlog. It was made more obvious in 62a532045e71 and related API simplification. It's resolved in favor of passing a revlog because the revlog verification code doesn't have a reference to a filelog. Differential Revision: https://phab.mercurial-scm.org/D7711

revlog: split the content verification of a node into a separate method This will be used by LFS to tune what is skipped. In the future, this could also be used by LFS to indicate which nodes tagged with `skipread` are simply in need of a blob fetch, so that they can be done in a batch later. (Currently, `skipread` also indicates censored data and errors.) Additionally, it could be used to cache the sha1 hash value for each blob so that large blobs don't need to be re-read and re-hashed if they are used by multiple nodes. Differential Revision: https://phab.mercurial-scm.org/D7710

verify: update comment to say that lfs doesn't need fulltext to check renames The reason is that `filelog.renamed()` indirectly calls `filelog.revision()`, which is what accesses the full text. However, LFS wraps `filelog.renamed()` and completely handles the case where an LFS blob is in play by using rawdata. I've got a test to demonstrate that this is the case, and prevent regressions. But the `skipread` flag is set on all lfs revisions when using `--no-lfs`, regardless of whether or not the blobs are local. Just above this, that flag is consulted, causing the rename checks to be skipped. That will need to be loosened up first. Differential Revision: https://phab.mercurial-scm.org/D7709

resourceutil: use `from importlib import resources` Without this patch, we get the following error from when trying to run hg with PyOxidizer: module 'importlib' has no attribute 'resources' I don't know what why that happens, but `from importlib import resources` is the form I would prefer anyway, so let's use that now that the impoort-checker has been fixed. Differential Revision: https://phab.mercurial-scm.org/D7701

import-checker: allow all absolute imports of stdlib modules Before this patch, we didn't allow imports like from importlib import resources (That's the reason I used `import importlib.resources` in D7629.) I think that form is still an absolute import, so I don't think we forbade on purpose. Differential Revision: https://phab.mercurial-scm.org/D7700
