copies: simplify the call to _merge_copies_dict Let's get the argument into the right order, then call the function once. Differential Revision: https://phab.mercurial-scm.org/D9417

copies: fast path no-op merge If the two sides of the merge are the same (they come an unaltered common ancestors) we don't need any merging. Differential Revision: https://phab.mercurial-scm.org/D9415

copies-rust: encapsulate internal sets on `changes` The goal is to eventually stop creating the underlying set. So we need to encapsulate the call first. Differential Revision: https://phab.mercurial-scm.org/D9306

copies-rust: pre-indent some code to clarify the next patch The next patch will need this new indentation, having it done explicitly beforehand makes that next patch clearer. Differential Revision: https://phab.mercurial-scm.org/D9305

copies-rust: combine the iteration over remove and copies into one In the underlying data, the copies information and the removal information are interleaved. And in the consumer code, the consumption could be interleaved too. So, we make the processing closer to the underlying data by fusing the two iterators into one. Later, we will directly consume the underlying data and that logic to combine the two iterators will be unnecessary. Differential Revision: https://phab.mercurial-scm.org/D9304

copies-rust: move is_ancestor caching within the rust code Now that the OrdMap merging is fast, smaller things start to matters. We move the caching of `is_ancestor` call within the Rust code. This avoid round-trip to Python and help us to shave more time on our slower case: Repo Cases Source-Rev Dest-Rev Old-Time New-Time Difference Factor ------------------------------------------------------------------------------------------------------------------------------------ pypy x0000_revs_x_added_0_copies d1defd0dc478 c9cb1334cc78 : 2.780174 s, 2.137894 s, -0.642280 s, × 0.7690 mozilla-try x0000_revs_xx000_added_x000_copies 89294cd501d9 7ccb2fc7ccb5 : 9.843481 s, 8.100385 s, -1.743096 s, × 0.8229 Note: I would happily have used native code for ancestors computation, however I failed (did not tried hard) to created a rust version that goes as fast as the current C version.

copies-rust: leverage the immutability for efficient update The immutable OrdMap has a diff function. That function yield items for each difference (missing in minor; missing in major; present in both, but different). We reorganise the manifest merging code to use this new function. We gather the data we would need to inject into the `minor` or `major` dict and eventually update one of them. The semantic of the merge itself is kept as is. Why are we doing this? Last year we contributed a patch making that diff function quickly detect some of the identical subsection when comparing two OrdMap cloned from a common ancestors (because they point to the very same node in memory). As a result: - That diff function is very fast in most of our cases, - It is important to maximize the "common" part by minimising the amount of unnecessary changes we do in theses Map. This is why we gather update for both and update the one with the smaller update. In practice, this yield a massive speed up on all our slow cases. Some examples below.: Repo Cases Source-Rev Dest-Rev Old-Time New-Time Difference Factor ------------------------------------------------------------------------------------------------------------------------------------ pypy x0000_revs_x_added_0_copies d1defd0dc478 c9cb1334cc78 : 33.527067 s, 2.780174 s, -30.746893 s, × 0.0829 netbeans x0000_revs_xx000_added_x000_copies 588c2d1ced70 1aad62e59ddd : killed(>120), 1.231869 s mozilla-central x00000_revs_x0000_added_x0000_copies 6832ae71433c 4c222a1d9a00 : killed(>120), 3.478747 s mozilla-try x0000_revs_xx000_added_x000_copies 89294cd501d9 7ccb2fc7ccb5 : 83.508590 s, 9.843481 s, -73.665109 s, × 0.1179 mozilla-try x0000_revs_x0000_added_x0000_copies e928c65095ed e951f4ad123a : 55.079813 s, 1.465128 s, -53.614685 s, × 0.0266 The performance compared to the Python code are now comparable (worst case are a score percent slower)" You an check the full table below for details.

phabricator: use the `http.timeout` config for conduit call Adding some timeout definitely help looping faster through the "bad connection" that I suffer from. So lets make it available. Differential Revision: https://phab.mercurial-scm.org/D9453

phabricator: introduce a `phabricator.retry` option For the past 2 days, my connection to phab.mercurial-scm.org became extremely poor. In practice this mean that any conduit call has a fairly high change to hang and die. Giving the amount of call done by the phabricator extension, it means the when I am lucky I can get 1 or 2 Diff to update after a few try, but anything sizeable doesn't have any hope to get through. This changesets introduce a new option for the fabricator extension to try retry failed command itself. So that I can get Diff through. As you can guess, this changeset managed to reach Phabricator thanks to itself. Differential Revision: https://phab.mercurial-scm.org/D9449

packaging: drop Disco (19.04) and add Focal (20.04) Disco support ended in January 2020, and Focal does not have an announced EOL. Something is now installing and configuring `tzdata`, which was throwing up an interactive prompt to configure the timezone. Aside from being hostile to automation, the prompt didn't actually accept input and hung the process. This propagates the host's timezone into the image via environment variable in order to skip the prompt, and avoid hardcoding a value. Differential Revision: https://phab.mercurial-scm.org/D9396

make: drop Trusty and Artful targets These were removed from the packaging makefile in 0363bb086c57. Differential Revision: https://phab.mercurial-scm.org/D9395

packaging: add `HG_DOCKER_OWN_USER` to `dockerdeb` like exists in `dockerrpm` I was getting build failures when it was trying to write to the working directory on CentOS 7 without this. It is basically the same as was added to the RPM builder in 4c0d4bbdc395. For some reason, this doesn't work with Xenial, and the only solution I found was to invoke it with UID 1000 on the host side. It doesn't EOL until April 2024, but it also has python 3.5.2, so this build complication is the least of the problems with supporting it after py2 is dropped.

copies-rust: pre-indent some code to clarify the next changeset The next changeset will massively rewrite the next function. However having a clear diff on the core semantic of the function will help making the next changesets clearer. So we do most of the churn beforehand. Differential Revision: https://phab.mercurial-scm.org/D9301

copies-rust: use immutable "OrdMap" to store copies information The large majority of time is currently spent coping and merging directories. the `IM` crate offer "immutable" Map, that use "copy on write" internally. The new object use the same API as the standard HashMap. So switching to it is trivial and it reduce copying cost significantly. More importantly, using immutable structure will unlock new possibility for a massive speed up of the "merging" part. This will came in a later changesets. Performance wise, we get very significant boost in the worst case. Below is some highlight of how we fare compared to the previous changeset.

copies: use the rust code for `combine_changeset_copies` Changeset centric copy tracing now use the rust code. The rust code focussed on simplicity and will be optimised later. So the performance is not great yet. Now that all the pieces are in place we can start working on performance in the coming changesets. Below is a table that summarize how slower we got: Repo Cases Source-Rev Dest-Rev Py-time Rust-time Difference Factor

rust: fix non-utf8 char in requirements.rs Apparently Phabricator detect `rust/hg-core/src/requirements.rs` file as non utf8 ‽, and mark it as binary. During application it ended up being non-utf8 and this made Rust (and as a result heptapod) very angry:: error: couldn't read hg-core/src/requirements.rs: stream did not contain valid UTF-8 --> hg-core/src/lib.rs:11:9 | 11 | pub mod requirements; | ^^^^^^^^^^^^ error: aborting due to previous error error: could not compile `hg-core`. The after "fixing", the file content has no character matching the following regexp: [^0-9-a-zA-Z /(|).,{}!\[\]:"&=>?_*-;<`'#] So we should be fine, unless Phabricator does something funny again.

dispatch: print the version of each extension in the bug report, if available Sometimes the wrong extensions is blamed, so we might as well print the version info for all of them. Additionally, since the internal extensions are never blamed, this is a good way to make the pygit2 version available in a bug report. Differential Revision: https://phab.mercurial-scm.org/D9440

dispatch: sort the loaded extension names in the bug report This makes a long list of extensions easier to read. On very rare occasion I've seen issues where the load order mattered, however that info should still be obtainable with `hg config extensions`.

dispatch: quote the extension when printing the bug report I think this reads better in the wall of text. Differential Revision: https://phab.mercurial-scm.org/D9438

dispatch: print the version of the extension being blamed in a bug report I don't know of a lot of extensions using this, but it seems like useful info in a bug report. Differential Revision: https://phab.mercurial-scm.org/D9437

git: show the version of `pygit2` with verbose version output This seems like useful info to have when debugging. I followed the precedent of hg-git, which prints something like: hggit external 0.9.0a1 (dulwich 0.19.15) We don't have a version number assigned (because it's internal), so it's just the parenthetical.

git: add the standard `testedwith` attribute Otherwise this shows up as an external extension. Differential Revision: https://phab.mercurial-scm.org/D9435

tests: add a comment that we're purposely testing py2 extension attributes Avoid someone unknowingly removing test coverage. There are tests for a properly byteified `testedwith` a few lines down. I don't see similar for `buglink`, but it's a trivial conversion to bytes, so I'm not concerned about testing the expected/wanted extension state.
