The performance of this has been looked at for quite some time, and some workflows are actually quite a bit faster than with the Python + C code. However, we are still (up to 20%) slower in some crucial places like cloning certain repos, log, cat, which makes this an incomplete rewrite. This is mostly due to the high amount of overhead in Python <-> Rust FFI, especially around the VFS code. A future patch series will rewrite the VFS code in pure Rust, which should hopefully get us up to par with current perfomance, if not better in all important cases. This is a "save state" of sorts, as this is a ton of code, and I don't want to pile up even more things in a single review. Continuing to try to match the current performance will take an extremely long time, if it's not impossible, without the aforementioned VFS work.

Before this change, we were unconditionally writing a branchmap file for the filter level passed to `update_disk`. This is actually counter productive if no update were needed for this filter level. In many case, the branch cache for a filter level is identical to its parent "subset" and it is better to simply keep the subset update and reuse it every time instead of having to do identical work for similar subset. So we change the `update_disk` method to only write a file when that filter level differ from its parent. This removes many cases where identical files were written, requiring multiple boring update in the test suite. The only notable changes is the change to `test-strip-branch-cache.t`, this case was checking a scenario that no longer reproduce the bug as writing less branchmap file result in less stalled cache on disk. Strictly speaking, we could create a more convoluted scenario that create a similar issue. However the next changeset would also cover that scenario so we directly updated that test case to a "no longer buggy" state.

The test suite mostly use small repositories, that implies that most changelog in the tests are inlined. As a result, non-inlined changelog are quite poorly tested. Since non-inline changelog are most common case for serious repositories, this lack of testing is a significant problem that results in high profile issue like the one recently fixed by 66417f55ea33 and 849745d7da89. Inlining the changelog does not bring much to the table, the number of total file saved is negligible, and the changelog will be read by most operation anyway. So this changeset is make it so we never inline the changelog, and de-inline the one that are still inlined whenever we touch them. By doing that, we remove the "dual code path" situation for writing new entry to the changelog and move to a "single code path" situation. Having a single code path simplify the code and make sure it is covered by test (if test cover that situation obviously) This impact all tests that care about the number of file and the exchange size, but there is nothing too complicated in them just a lot of churn. The churn is made "worse" by the fact rust will use the persistent nodemap on any changelog now. Which is overall a win as it means testing the persistent nodemap more and having less special cases. In short, having inline changelog is mostly useless and an endless source of pain. We get rid of it.

This work around any deviciency/limitation of the clone process. In our case this ensure the persistent nodemap exist with valid content. Ideally, the cloning process would also do "the right thing". However since older server will never be able to do "the right thing". The local workaround will be necessary anyway. I am not worried by the performance impact of this as `hg clone` is non-instant on large repositories where is could matters. Warming the cache if they are already correct is very fast. And if they are not already warm, this seems like a good time to do so. This impact various test as more cache are now warmed sooner, all the change should be harmless.

Support for bundle2 streaming clones has been shipped in Mercurial 4.5 (7eedbd5d4880), but was never activated by default. It's time to have more people use it. The new format allows streaming clones to transport cache (hooray for speed) and phaseroots (fixes phase-related issues). Changes in tests: bundle2 capabilities now have "stream=v2" (plus a '\n' as a separator) and therefore take 14 bytes more: "%0Astream%3Dv2". Tip for tests that have data encoded with CBOR: 0xd3 - 0xc5 = 14. $USUAL_BUNDLE2_CAPS$ replaces $USUAL_BUNDLE2_CAPS_SERVER$, which is the same thing, but without "stream=v2". Since streaming clones now also transfer caches, the reported byte and file counts are higher (e.g. 816 bytes in 9 files instead of 613 bytes in 4 files, a bit of --debug and manual math confirms that the caches take these extra 203 bytes in 5 files).

When interacting with non-publishing repository or bundle, it is useful to have some information about the phase of the changeset we just pulled. This changeset updates the "new changesets MIN:MAX" output to also includes phases information for non-public changesets. Displaying extra data about non-public changesets means the output for exchange with publishing repository (the default) is unaffected.

Before, we used the default store, which was based on fncache and dotencode. After attempting to port tests to work with the simple store, I realized that fncache was more trouble than it is worth. This commit implements a proper store type for the simple repo - one that isn't based off fncache. This causes a number of new test failures because of tests expecting the full fncache store filename encoding. I may extend the store format in a subsequent commit to take the filename encoding parts of fncache that we can take (basically everything except hash encoding, since that isn't reversible). But for now, let's use encoded store. As part of this, we implement proper requirements support for repos created with the simple store. This should have been done from the beginning, as a requirement is needed to lock out clients that don't understand a storage format. A new hghave feature advertising the presence of fncache in repos has been added. Most tests touching the fncache are now conditional on that feature. Other tests have added the optional repo requirement to output. Differential Revision: https://phab.mercurial-scm.org/D3095

bundlerepo is... going to be difficult to port to an alternate store because it assumes revlogs for storage and essentially overlays the contents of a bundle onto a fake revlog-like primitive. It will be a good test case for our eventual new storage interface. Refactoring bundlerepo to make it work with non-revlog storage is going to be a bit of work. So for now, let's refuse to use the simple store repo when a bundlerepo is in play. A new test requirement advertising support for treating bundle files as repo instances has been added. Some tests have been made conditional on this feature. Additional tests will be annotated in subsequent commits. Having positive opt-in to repo features will be simpler in the long run because it will allow multiple storage backends to declare feature support and we won't have to annotate each test with the set of repo backends that are supported. Again, we'll probably want better integration between repo features and tests. But this is the easiest we can do at the moment. Differential Revision: https://phab.mercurial-scm.org/D3060

`hg pull <bundle>` uses the special "bundlerepo" repository. The bundlerepo code makes many assumptions about the storage of repositories. It will be difficult to teach bundlerepo to use non-revlog storage before a better storage interface is established. Many test failures using our "simple store" are related to bundlerepo: the simple store just isn't compatible with bundlerepo because of storage assumptions in bundlerepo. In order to mitigate the impact of bundlerepo on our code base, this commit changes various tests to use `hg unbundle` instead of `hg pull`. This bypasses the bundlerepo code. Tests exercising exchange functionality have not been altered, as they should be using `hg pull` and going through the bundlerepo code paths.

These fields are an implementation detail of revlog storage. As such, they are not part of the generic storage "index" interface and shouldn't be displayed by default. Because we don't have another way to display these fields, we've retained support for printing these fields via --verbose. Yes, I know we should probably be doing all this formatting using modern formatting/templater APIs. I didn't feel like scope bloating this patch.

Revlog index data consists of generic index metadata that will likely be implemented across all storage engines and revlog-specifc metadata. Most tests printing index data only care about the generic fields. This commit drops the printing of the base revision from `hg debugindex`. This value is an implementation detail of revlogs / delta chains. If tests are interested in verifying this implementation detail, `hg debugdeltachain` is a better command. Most tests were skipping over this field anyway. Tests that weren't looked like they were newer. So my guess is we forgot to make them skip the field to match the style of the older tests. This reinforces my belief that the base revision is not worth having in `hg debugindex`. Differential Revision: https://phab.mercurial-scm.org/D3027
