errors: raise StateError when push fails because it creates new heads I decided to raise `StateError` here because the local and remote repos are in an incompatible state. I think remote errors (exit code 100) should be when something goes wrong on the remote and there's nothing the user can do. Differential Revision: https://phab.mercurial-scm.org/D9391

errors: raise InputError on early parse error in dispatch I didn't think this would have any effect on the tests, but it does because the catching in `scmutil.callcatch()` still happens. That's because `dispatch` passes in the function that includes the parsing as an argument to that function. I initially used `ConfigError` here but Matt Harbison convinced me to use `InputError`. I think that makes sense since error is not in a config file. Differential Revision: https://phab.mercurial-scm.org/D9387

copies: make calculating lazy for dir move detection's "addedfiles" The information calculated here was only needed if (a) --debug was specified, or (b) a directory move was plausibly detected. With tree manifests (especially in my pathological repo and with our custom setup), pre-calculating the `u1` and `u2` can be quite slow, and it's not even necessary in many cases. Let's delay calculating it until we know it's actually necessary. This should have no observable differences in output. ### Performance I ran a rebase command in my pathological repo, rebasing two nodes across several public phase commits, but where no directory copies exist in any of the paths I'm tracking. #### Before ``` Time (mean ± σ): 3.711 s ± 0.061 s [User: 0.3 ms, System: 1.5 ms] Range (min … max): 3.640 s … 3.827 s 10 runs ``` #### After ``` Time (mean ± σ): 868.3 ms ± 10.1 ms [User: 0.5 ms, System: 1.2 ms] Range (min … max): 856.6 ms … 883.6 ms 10 runs ``` Differential Revision: https://phab.mercurial-scm.org/D9567

mergetools: add new conflict marker format with diffs in I use 3-way conflict markers. Often when I resolve them, I manually compare one the base with one side and apply the differences to the other side. That can be hard when the conflict marker is large. This patch introduces a new type of conflict marker, which I'm hoping will make it easier to resolve conflicts. The new format uses `<<<<<<<` and `>>>>>>>` to open and close the markers, just like our existing 2-way and 3-way conflict markers. Instead of having 2 or 3 snapshots (left+right or left+base+right), it has a sequence of diffs. A diff looks like this: ``` ------- base +++++++ left a -b +c d ``` A diff that adds one side ("diff from nothing") has a `=======` header instead and does not have have `+` prefixed on its lines. A regular 3-way merge can be viewed as adding one side plus a diff between the base and the other side. It thus has two ways of being represented, depending on which side is being diffed: ``` <<<<<<< ======= left contents on left ------- base +++++++ right contents on -left +right >>>>>>> ``` or ``` <<<<<<< ------- base +++++++ left contents on -right +left ======= right contents on right >>>>>>> ``` I've made it so the new merge tool tries to pick a version that has the most common lines (no difference in the example above). I've called the new tool "mergediff" to stick to the convention of starting with "merge" if the tool tries a regular 3-way merge. The idea came from my pet VCS (placeholder name `jj`), which has support for octopus merges and other ways of ending up with merges of more than 3 versions. I wanted to be able to represent such conflicts in the working copy and therefore thought of this format (although I have not yet implemented it in my VCS). I then attended a meeting with Larry McVoy, who said BitKeeper has an option (`bk smerge -g`) for showing a similar format, which reminded me to actually attempt this in Mercurial.

simplemerge: write output only once it's complete `simplemerge()` can write either to `ui.fout` or to the file context (for in-memory merge). This patch simplifies the code a bit by making it build the output the same way regardless of where it's written, and then writes the whole output at once. I don't think it will be a problem that we don't output anything until the whole file is merged even if the file is large. Differential Revision: https://phab.mercurial-scm.org/D9550

hghave: update the check for virtualenv This started as `hghave --test-features` failing on Windows in `test-hghave.t`. IDK how this worked, as neither my Linux nor Windows machines have the old attribute with virtualenv 20.2.2, even on py2. I think this was noticed recently because 357d8415aa27 mentioned an AttributeError, and mitigated by making this py2 only. But as mentioned, this is also a problem on py2 (where the failure was observed). When I got this working by removing the attribute reference, the command in the test failed because the `--no-site-package` argument was removed some time ago. Therefore, this backs out 357d8415aa27 and references a known good attribute (which was done to suppress the warning about an unused import) that also ensures the command does not need the argument. Since there appears to be (minor) broken stuff on py3, manually apply the `no-py3` guard that was backed out of the check itself. Differential Revision: https://phab.mercurial-scm.org/D9547

treemanifest: stop storing full path for each item in manifest._lazydirs This information is obtainable, if needed, based on the lazydirs key (which is the entry name) and the manifest's `dir()` method. ### Performance This is actually both a memory and a performance improvement, but it's likely to be a very small one in most situations. In the pathological repo I've been using for testing other performance work I've done recently, this reduced the time for a rebase operation (rebasing two commits across a public-phase change that touches a sibling of one of my tracked directories where the common parent is massive (>>10k entries)): #### Before ``` Time (mean ± σ): 4.059 s ± 0.121 s [User: 0.9 ms, System: 0.6 ms] Range (min … max): 3.941 s … 4.352 s 10 runs ``` #### After ``` Time (mean ± σ): 3.707 s ± 0.060 s [User: 0.8 ms, System: 0.8 ms] Range (min … max): 3.648 s … 3.818 s 10 runs ``` Differential Revision: https://phab.mercurial-scm.org/D9553

extensions: avoid including `__index__` in the disabled extension list This generated module contains a dictionary of all bundled extension names and their help for builds that cannot enumerate extensions in the filesystem. The disabled list gets displayed in `hg help extensions`, and is also used by `setup.py` to populate `__index__.py` when building. I haven't seen it sneak into either py2exe or PyOxidizer builds, but it does show up when running tests locally after having created an installer.

windows: continue looking at `%HOME%` for user config files with py3.8+ The `%HOME%` variable is explicitly called out in `hg help config` as a location that is consulted when reading user files, but python stopped looking at it when expanding '~' in py3.8+.[1] Restore that old functionality by copying in the old implementation (and simplifying it to just use bytes). It could be simplfied further, since only '~' is passed, but I'm not sure yet if we need to make this a generic utility function on Windows. There are other uses of `os.path.expanduser()`, but this is the only case I know of that documents `%HOME%` usage. (The reason for removing it was that it typically isn't set, but it actually is set in MSYS and PowerShell, and `%HOME%` and `%USERPROFILE%` are different in MSYS. I could be convinced to just replace all uses with this as a general utility, so we don't have to think too hard about BC.)

rhg: use persistent nodemap when available … for node ID → revision number lookups, instead on linear scan in a revlog. Differential Revision: https://phab.mercurial-scm.org/D9520

persistent-nodemap: properly ignore non-existent `.nd` data file This code was meant to handle the case of a nodemap docket file pointing to a nodemap data file that doesn’t exist (anymore), but most likely caused an `UnboundLocalError` exception instead when `data` was used on the next line without being defined. This case is theoretically possible with a race condition between two hg processes, but is hard to reproduce or test: * Process A reads a docket file and finds a UID in it that points to a given data file name. * Process B decides that this same data file needs compacting. It writes a new one with a different UID, overwrites the docket file, then removes the old data file. * Only then process A tries to a open a file that doesn’t exist anymore.

diff: add --from and --to flags as clearer alternative to -r -r I think it was mistake to let the `-r` flag accept two revisions in `hg diff` in 98633e60067c (Support for 0, 1, or 2 diff revs, 2005-05-07). The command clearly acts on two revisions and having a single flag to indicate which those are is unclear. It got worse when it started accepting revsets as input. This patch introduces `--from` and `--to` flags, each taking a single revision and each defaulting to the working copy. That means that `hg

commandserver: handle IOError related to flushing of streams After dispatch, without chg we have handling of flushing of streams and exception handling related to it. The exception handling part is important because there can be exceptions when flushing fout or ferr. One such case is in `test-basic.t` which was failing on python3+chg without this patch as this handling was missing from chg.

run-tests: stuff a `python3.exe` into the test bin directory on Windows Windows doesn't have `python3.exe` as part of the python.org distribution, and that broke every script with a shebang after c102b704edb5. Windows itself provides a `python3.exe` app execution alias[1], but it is some sort of reparse point that MSYS is incapable of handling[2]. When run by MSYS, it simply prints $ python3 -V - Cannot open That in turn caused every `hghave` check, and test that invokes shebang scripts directly, to fail. Rather than try to patch up every script call to be invoked with `$PYTHON` (and regress when non Windows developers forget), copying the executable into the test binary directory with the new name just works. Since this directory is prepended to the system PATH value, it also overrides the broken execution alias. (The `_tmpbindir` is used instead of `_bindir` because the latter causes python3.exe to be copied into the repo next to hg.exe when `test-run-tests.t` runs. Something runs with this version of the executable and subsequent runs of `run-tests.py` inside `test-run-tests.t` try to copy over it while it is in use, and fail. This avoids the failures and the clutter.) I didn't conditionalize this on py3 because `python3.exe` needs to be present (for the shebangs) even when running py2 tests. It shouldn't matter to these simple scripts, and I think the intention is to make the test runner use py3 always, even if testing a py2 build. For now, still supporting py2 is helping to clean up the mess that is py3 tests.

copies-rust: parse the changed-file sidedata directly in rust It does not make much sense to parse the data into python object using slow python code to later turn them into rust object. We directly pass the binary blob and use it directly in Rust. Ideally we could directly read the sidedata in Rust, using a revlog in Rust. However we do not have this ready to use yet. This more direct approach provides a nice speedup over the board. Especially five cases that we previously too slow to return in the previous changeset are not able to finish. Notably, we are now significantly faster than the Python version of this code in all the meaningful cases. I looked at the various cases that remains significantly slower then the filelog version and they are currently 3 main source of slowness: * The isancestor computation: even if we cache them, if the revs spawn over a large amount of history the ancestry checking is still quite expensive. Using a different approach more centered on the graph we are currently considering might yield significant speed. * Merging of the map from the two parents: in some case, this climb up to ⅔ of the time spent in copy tracing. See inline comment for idea to handle this better. * Extracting data from the filelog. I would like to think this mostly comes from the fact my test repositories pre-date Valentin Gatien-Baron improvement of the `files` field (99ebde4fec99) and that more recent revisions will be faster to fetch. Further testing on this aspect is needed.

upgrade: start moving the "to be happening" data in a dedicated object The upgrade code has a lot of logic to determine which action needs to be performed depending of various element (sometimes depending from each other). It would be nice to have a consistent object representing this. That could be cleanly passed and avoid some logic duplication. So we create this object as a start.

hg: add user-site to `sys.path` on Windows to allow pip-installed extensions This has been in the TortoiseHg builds for several cycles now on Windows, and even longer on macOS. It allows an extension to be configured with `ext =` syntax, instead of requiring the full path to be specified. It's confusing for a user to be hit with messages about not being able to load extensions, based solely on which `hg.exe` is being run. This only applies to py2exe binaries, since wrapper.exe already sees into the user site area. There are no frozen binaries on other platforms (that I'm aware of), and an equivalent change will need to be made to `dispatch.py` in order to work with PyOxidizer, since it bypasses this module completely. (It also has the ability to use the `site` module, so it will look completely different.) Differential Revision: https://phab.mercurial-scm.org/D9531

phab-refresh: do not pick draft changeset from the bare "default" branch My initial test overlooked a common case: draft changeset on the default branch.

log: do not accept string-matcher pattern as -u/-b/-B parameter I'm pretty sure this is a bug introduced after we've switched the filtering backend to revset matcher.

log: do not override other filtering and sorting options by --bookmark This basically reimplements 0aa118f18d4b 'log: add bookmark option to "hg log"'. Before, any other filtering options but --rev were ignored. -G didn't work either since the ordering constraint wasn't enforced.

scmutil: extract function that builds revset expr to select bookmark branch This is needed to process "log -B" option properly. "log" options have to be translated to a revset expression, not to an evaluated set.

scmutil: document that bookmarkrevs() ignores non-head bookmark branch "- ancestors(head() and not bookmark(%s))" excludes the bookmarked branch itself if bookmark(%s) is not a head. I'm a bit surprised by this behavior while writing "log -B" tests, so let's document it.

cext: add .pyi files for C extensions I'm unsure if all the annotations are completely accurate. But having these helps type checkers reason about our C extensions. Differential Revision: https://phab.mercurial-scm.org/D9281

phabricator: allow local revisions to be specified with `phabupdate` It's way easier and less error prone to specify a revset after importing a series than to manually type in a series of Differentials. Unlike most revision oriented commands, this requires the `--rev` option explicitly because the existing `DREVSPEC` doesn't need to have the leading 'D', and therefore the meaning is ambiguous. I wouldn't have a problem giving precedence to the local revnum, but `phabread` and `phabimport` also use DREVSPEC, and local revisions make no sense there. I would be fine with modifying that definition to require the leading 'D', but I'm not sure how many people are used to not specifying it. Differential Revision: https://phab.mercurial-scm.org/D9356

If the stuff before "line ###" is long, there's no separation between the function name and the "line" string. 2. If the stuff before "line ###" is really long, there's excessive separation between the "line" string and the line number. 3. We frequently have 4-digit line numbers, the code on the right wasn't dynamically indented and ended up quite messy looking. To solve these problems, I've added a ", " prefix before "line" iff it would otherwise not have any separation such as spaces. I've added a 'max' so that we never use a negative width (which is the cause of problem #2 above), and I've added a default assumption of 4 digit line numbers (but again using a 'max' so this shouldn't cause problems if we go beyond that.

run-tests: allow some slack about 'waiting on lock' message It is common to run the tests on very loaded machine when concurrent run might take a bit longer. Such message are usually harmless, but anoying as they break the tests. Test that explicitly depends on this value have been adjusted. This make them more robust anyway. A fun case was `test-clone-pull-corruption.t` which, without the previous changeset introducing extra flushing, ended use having a line 31 (`pulling from ../source`) changing order because the warning message was no longer flushing stdin before using stderr (stderr being invisible in the test).

match: skip walking up the directory hierarchy if the number of pats are small Previously, we would receive a path like abc/def/ghi and "walk up" the directory hierarchy, checking abc/def, abc, and `b''` to see if they were in the set of prefixes that this matcher covered. We did this indiscriminately - we generated all of these paths even if the set of prefixes the matcher covered was completely empty, which is the case for a lot of repos at my company (the narrow matcher we use is usually non-recursive). This brings the time for a rebase in one of my repos from 12.20s to 10.87s. In this particular repo, this is entirely due to the `len(prefix_set) == 0` check, as I do not have any recursive patterns in the narrowspec.

heptapod-ci: automatically refresh existing phabricator Diff on push If a changeset have been submitted to Phabricator and a new version is pushed to heptapod, we should refresh the state on Phabricator. If we do not do this, they are a risk of an older version being applied from Phabricator. In this situation content-divergence will be (rightfully) detected by evolution. We only refresh the Diff if the test pass, to avoid updating Phabricator with broken content. Differential Revision: https://phab.mercurial-scm.org/D9451

contrib: add a small script to refresh all diff in the current stack This will be useful to introduce automatic refresh through heptapod. Differential Revision: https://phab.mercurial-scm.org/D9460

tests: conditionalize return code on chg in test-config.t If there is any error while reading config, chg just returns 255 instead of 30. It seems to me that we cannot conditionalize only return codes in output using trailing `(chg !)` and hence used testcases. The test was failing with chg but after this patch, it now passes. Differential Revision: https://phab.mercurial-scm.org/D9463

tests: update test-chg.t with output change Since this part of tests is only run with chg, hence it didn't get updated when the error message changed. Differential Revision: https://phab.mercurial-scm.org/D9414

rust-format: pin the formatted to a specific nightly version Version 1.50 change the way rust-format behave. We pin the version for now, we can figure out something better later.

copies: clarify the return of _merge_copies_dict I misused that function twice in the past few days, so lets clarify the API. Differential Revision: https://phab.mercurial-scm.org/D9418

copies: avoid unwanted side effect from one branch to another Without this copy, change in a one descendant branch (With "remove" change only) could affect computation on another descendant branches. This was not caugh by the test because the test graph are "too simple". I started writing more test in that regards, but I a submitting this changes earlier because I want to get more code landed to allow other optimisation work to happens. Differential Revision: https://phab.mercurial-scm.org/D9416

rhg: use `format_bytes!` for error messages This change also includes a formatting changing with the new `rustfmt` version, but I'm expecting it to have already been applied in another patch by the time this lands. Differential Revision: https://phab.mercurial-scm.org/D9407

packaging: don't use plain 'python' if another python has been specified Before this change, packaging on CentOS 8 failed because 'python' is used instead of 'python3'. Change was tested with: - make docker-centos7 - make docker-centos8 - make docker-ubuntu-bionic Differential Revision: https://phab.mercurial-scm.org/D9464

packaging: add pygit2 to the py3 Windows installers This is needed to be able to use the git extension. The extension no longer complains about the library being not installed, but `hg log -r .` on a repo that works in WSL yielded a TypeError: ... File "mercurial.hg", line 188, in _peerorrepo File "mercurial.localrepo", line 3224, in instance File "mercurial.localrepo", line 623, in makelocalrepository File "hgext.git", line 117, in _makestore File "hgext.git", line 48, in __init__ TypeError: Repository unable to unpack backend. Differential Revision: https://phab.mercurial-scm.org/D9405

upgrade: directly use the upgrade action constant This make the code simpler and will make it simpler to add more case in the future. Differential Revision: https://phab.mercurial-scm.org/D9467

upgrade: rename UPGRADE_FILELOG to UPGRADE_FILELOGS They are multiple filelog to upgrade, so this seems more accurate. Differential Revision: https://phab.mercurial-scm.org/D9466

bisect: add `-G` to an `hg log` command in a test This helps readers see what shape of DAG to expect Differential Revision: https://phab.mercurial-scm.org/D9373

bisect: refactor to work on a list of revspecs This will allow adding a `--rev` flag that can be passed more than once. Differential Revision: https://phab.mercurial-scm.org/D9372

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

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.

extensions: avoid a crash when the version isn't properly byteified on py3 We already force bytestr on the `testedwith` and `buglink` attributes in dispatch.py when generating a bug report with a similar comment about not every extension being ported to py3.

copies: introduce the hg-cpython wrapper for `combine_changeset_copies` This patch focus on the `hg-cpython` part of this work. Bridging the python code with the new rust code in `hg-core`. The next patch will actually plug this in the python code. The rust code use multiple Python callback, python related error within this callback are not expected unless they are a programming error or a data corruption. In addition, these callback will slowly be replaced by native Rust code. For these reasons, we use will deal with unexpected error within this callback using rust Panic and let the `rust-cpython` layer deal with raising a Python exception. The code dealing with the ChangedFile instance is repeating itself a lot. I did not factor these duplication out because that whole code will get replaced by entirely different one in a handful of changesets. Differential Revision: https://phab.mercurial-scm.org/D9298

copies: introduce a basic Rust function for `combine_changeset_copies` This new function mirror the python code. This first implementation does a lot of data copies and is therefore quite slow. However my goal here is to create a simple "frame" from where to start adding optimization. This patch focus on the `hg-core` part of this work. Coming patches will do the necessary `hg-cpython` work to be able to use this from Python. Differential Revision: https://phab.mercurial-scm.org/D9297

ui: ensure `getpass()` returns bytes Previously, this could return either bytes or str. I'm not sure which direction we should go in, but since the input is bytes, I guess bytes makes sense as output. `debuguigetpass` crashed because it assumed bytes would be returned, `sslcontext.load_cert_chain()` is happy with bytes or str if the type info in PyCharm is correct, and `smtplib.SMTP.login()` wants str. I couldn't figure out how to test this, because the test stalls for input with `echo test | hg debuguigetpass --config ui.interactive=1`, likely because it drains stdin before prompting. The custom input reading with `ui.nontty=1` does not. I'm also a bit concerned with all of this encoding/decoding. The existing code in the mail module uses `encoding.strfromlocal()`, but the username and password are ascii encoded/decoded in `mercurial.url.passwordmgr.find_user_password()` with `pycompat.{str,bytes}url()`. I'm not sure if this inconsistency could cause subtle compatability issues. Differential Revision: https://phab.mercurial-scm.org/D9375

I do happen to have a python.exe on PATH in `$LOCALAPPDATA/Microsoft/WindowsApps`, but it appears to be 0 bytes (likely because of permission issues), and doesn't run: $ python -V - Cannot open Pulkit hit the same error as I did though, so it isn't just my system: $ make -C . local make: Entering directory `/home/Dell/repos/hg-committed` python setup.py \ build_py -c -d . \ build_ext -i \ build_hgexe -i \ build_mo - Cannot openmake: *** [local] Error 1 The `py.exe` dispatcher lives in the Windows directory (so it is on PATH), looks up the python.org installation, and invokes that interpreter directly. I get a warning with py39, but if it's our issue, it was an existing one: $ make -C .. local make: Entering directory `/c/Users/Matt/hg' py -3 setup.py \ build_py -c -d . \ build_ext -i \ build_hgexe -i \ build_mo C:\Users\Matt\AppData\Local\Programs\Python\Python39\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first. warnings.warn( The end result is a py3 based hg.exe that annoyingly won't run because it can't find python39.dll. It will run tests (the ones without the `python3` shbang line anyway), because the test runner adjusts PATH to include the python running it.

heptapod-ci: hosting base image on registry.heptapod.net We are now touching the rate limits of Docker Hub.

context: small update to ctx.status doc The order of the "arguments" were not too clear, so we update the documentation to clarify that.

errors: use exit code 10 for parse errors Now that `ParseError`s raised while reading the config file has been converted into `ConfigError`s, the remaining parse errors should all be "input errors" (i.e. exit code 10), according to https://www.mercurial-scm.org/wiki/ErrorCategoriesPlan. Differential Revision: https://phab.mercurial-scm.org/D9332

errors: raise ConfigError on failure to parse config file This replaces two raises of `ParseError` by `ConfigError`, which makes it so we get the desired exit code when `ui.detailed-exit-code` is enabled. Because the exceptions include a location, I had to add that to `ConfigError` as well. I considered making `ConfigError` a subclass of `ParseError`, but it doesn't feel like it quite passes the "is-a" test. I used "config error: " as prefix for these errors instead of the previous "hg: parse error: ", which seems a little less accurate now (and, as I've said before, I don't know what the "hg: " part is supposed to signify anyway). I can easily be convinced to change the prefix to something else (including "abort: "). Some of the exceptions raised here mean that we fail to even load the `ui` object in the `dispatch` module. When that happens, we don't know to use detailed exit codes, so some tests (e.g. `test-hgrc.t`) still see exit code 255. I'll try to get back to that later. It should be possible to give detailed exit codes if at least part of the config can be read (e.g. when the system-wide one enables detailed exit codes and the user's config fails to parse).

histedit: don't crash if commit message is empty If the commit message is empty, histedit will crash before this patch because it assumes that `summary.splitlines()` is non-empty. One of our users at work ran into this crash for a commit that was created by an internal system. I don't think we have a good way of testing this because it's hard to create a commit with an empty commit message. I've added a comment to help prevent regressions.

copies: cache the ancestor checking call when tracing copy A good share of the time spent in this function is spent doing ancestors checking. To avoid spending time in duplicated call, we cache the result of calls. In the slower case, this provide a quite significant performance boost. Below are the result for a set of selected pairs (many of them pathological): (And further down is another table that summarize the current state of filelog based vs changeset base copy tracing) The benchmark have been configured to be killed after 6 minutes of runtime, which mean that any detect slower than 2 minutes will be marked as "killed". This drop some useful information about how much slower these case are… but also prevent 99% of the benchmark time to be spent on case that can be labelled "very slow" anyway.

of the current "filelog centric" algorithm, with the "changeset centric" one, we just modified. The changeset centric algorithm is a significant win in many scenario, but they are still various cases where it is quite slower. When many revision has to be considered the cost of retrieving the copy information, creating new dictionaries, merging dictionaries and checking if revision are ancestors of each other can slow things down. The rest of this series, will introduce a rust version of the copy tracing code to deal with most of theses issues.

errors: remove ParseError.args With the previous few patches, it is no longer needed (as far as the test suite can tell anyway). Differential Revision: https://phab.mercurial-scm.org/D9354

errors: let ParseError use Abort.__bytes__ The function is no longer used anywhere as far as our tests can tell, so there's no need to have a custom version of it. Differential Revision: https://phab.mercurial-scm.org/D9353

config: clean up message about ignored untrusted config The error message relied on Python's default formatting of arguments to an Exception's constructor. Let's try to make it a little more readable for users. Differential Revision: https://phab.mercurial-scm.org/D9352

tests: use new ParseError.format() in test-trusted.py Differential Revision: https://phab.mercurial-scm.org/D9351

errors: make ParseError a subtype of Abort I didn't plan this before, but the previous two changes made it really easy to make `ParseError` a subtype of `Abort`. It seems obvious with hindsight that I *should* have planned it :) Differential Revision: https://phab.mercurial-scm.org/D9350

tests: make doctests not depend on str(ParseError()) format `ParseError` implements `__bytes__`, but it doesn't implement `__str__`, so it gets the default `__str__` implementation. The next patch will make it so `ParseError` gets a `__str__` implementation, which changes the format slightly. This prepares by making us not depend on the format. Differential Revision: https://phab.mercurial-scm.org/D9349

errors: format "abort: " text in a new Abort.format() method This remove some duplication we had. Differential Revision: https://phab.mercurial-scm.org/D9348

errors: make formatparse() an instance method on ParseError It's just a little simpler this way. Don't ask me what the "hg: " prefix signifies to the user, I just left it as it was. I think we should consider changing the prefixes later (maybe always use "abort: ", or maybe use more specific prefixes in general). Differential Revision: https://phab.mercurial-scm.org/D9347

errors: create "similarity hint" for UnknownIdentifier eagerly in constructor No code wanted to do anything but to produce a hint from it anyway, so we might as well just store the hint in the exception (which already extended `Hint`). That way we can easily convert it to a `ConfigException` when it's parsing of configuration that fails. I was wondering if the purpose of lazily creating the string was so we don't create it in cases where it won't get printed anyway. However, I couldn't find any places where that could happen. If we do find such places, we could instead revert to making it lazy but add a function on `UnknownIdentifier` for creating the hint string. I dropped the comment saying "make sure to check fileset first, as revset can invoke fileset", which was added in 4e240d6ab898 (dispatch: offer near-edit-distance suggestions for {file,rev}set functions, 2015-01-26). I couldn't figure out what it meant. The author of that patch also did not remember the reason for it. Perhaps changes that have happened since then made it so it no longer matters. Differential Revision: https://phab.mercurial-scm.org/D9346

errors: move similarity_hint() to error module I want to be able to reuse it from `UnknownIdentifier`'s constructor. Moving it results in a new import of `difflib` in the `error` module. There was a comment at the top of `error.py` saying "Do not import anything but pycompat here, please", which was added (except for the "pycompat" bit) in 08cabecfa8a8 (errors: move revlog errors, 2009-01-11). I don't know the reason for the comment. I'm guessing the point was to not make the module depend on other Mercurial modules. If that was it, then importing `difflib` should be fine. Sorry about the churn (I moved this code from the `dispatch` module to the `scmutil` module very recently). Differential Revision: https://phab.mercurial-scm.org/D9345

errors: morph reportsimilar() into similarity_hint() The next step is to eagerly create the hint in `UnknownIdentifier`'s constructor. Differential Revision: https://phab.mercurial-scm.org/D9344

errors: restructure formatparse() to clarify conditions a bit The `similar` list will be calculated only for `error.UnknownIdentifier`. It was then printed only if `inst.location is None`, which is true for that exception type, but it's an indirect condition to rely on. Also, it looked from the code like it could both report similarities and print a hint. That would be a little awkward because the similarity report looks similar to the hint (both are printed within parentheses). I also added a `elif` to clarify that. I plan to refactor this more coming patches so the similarity report actually is a hint. Differential Revision: https://phab.mercurial-scm.org/D9343

transaction: split new files into a separate set Journal entries with size 0 are common as they represent new revlog files. Move them from the dictionary into a set as the former is more dense. This reduces peak RSS by 70MB for the NetBSD test repository with around 450k files under .hg/store. Differential Revision: https://phab.mercurial-scm.org/D9278

transaction: change list of journal entries into a dictionary The transaction object used to keep a mapping table of path names to journal entries and a list of journal entries consisting of path and file offset to truncate on rollback. The offsets are used in three cases. repair.strip and rollback process all of them in one go, but they care about the order. For them, it is perfectly reasonable to read the journal back from disk as both operations already involve at least one system call per journal entry. The other consumer is the revlog logic for moving from inline to external data storage. It doesn't care about the order of the journal and just needs to original offset stored. Further optimisations are possible here to move the in-memory journal to a set(), but without memoisation of the original revlog size this could turn it into O(n^2) behavior in worst case when many revlogs need to migrated. Differential Revision: https://phab.mercurial-scm.org/D9277

transaction: rename find to findoffset and drop backup file support transaction.find used to support access to both the regular file and backup file list. They have different formats, so any consumer has to be aware of the difference alredy. There is no in-core consumer for the backup file access, so don't provide it. Differential Revision: https://phab.mercurial-scm.org/D9276

transaction: drop per-file extra data support At the moment, transactions support an optional extra data argument for all files to be stored in addition to the original offset. This is used in core only by the revlog inline to external data migration. It is used to memoize the number of revisions before the transaction. That number of can be computed during the walk easily, so drop the requirement. Differential Revision: https://phab.mercurial-scm.org/D9275

templates: define a {onelinesummary} keyword It is sometimes useful to be able to use the configured `command-template.oneline-summary` in higher-level templates. For example, I would like to use it in an internal template that lists commits in a "review unit" (kind of a pull request). This patch adds support for that. We may want to define a way of formatting a context using a command-specific override (from `command-templates.oneline-summary.<command>`), but that will have to be a template function instead. I don't plan to do that, but I'm mentioning it now in case reviewers would prefer that we use a no-arg function (i.e. `{onelinesummary()}`) already today to prepare for that.
