tag: disallow tagging the working directory It's kinda silly, but a clear error message is better than a stacktrace about subscripting `None` when trying to generate the default commit message. I'm surprised that `.revsingle(..).node()` returns None instead of `nodemod.wdirid`, but now there's a test to catch if this changes.

test: fix the flakyness in test-remotefilelog-local.t I now get about 80% of my `test-chg` CI run that fails on flakyness in this tests. It turns out this is only ambiguous status that end up doing file download. So… calling status early will do that potential download separately and the calls we scrutinize during that test will be just fine.

fix: add more information to the debug output The previous debug output did not help to understand which file where fixed in which revision. The new output should cover that.

hgweb: unbyteify the 100-continue check The environment seems to be `str` or `tuple[int]`, and the same check in `wsgicgi.py` is already `str` based, so I suspect this was wrong. I think what happened here is that the string wasn't `r''` prefixed in 482d6f6dba91 like `wsgicgi.py`, so it got wrongly byteified in 687b865b95ad when converting to byte literals en masse.

setup: treat error output and non-zero return code differently Choking on Mercurial's stderr mean armless warning can derails the whole install process. We do like to be able to issue warning to people so we stop considering any stderr is a fatal mistake. This allow us to actually boostrap a version of Mercurial without loosing to many sanity point. For example in case where evolve is not loaded, something that happens when the recorded version is malformatted. Creating a wonderful ouroboros.

setup: make the version computation process more resistant The tag fetching might return and empty string¹, from there everything derails quickly. As setup tools becomes more picky about version format we make the whole seems a bit more robust. The resulting version will be obviously weird, but at least it will actually install itself. [1] This is a problem we will address in the next changesets.

bundlerepo: enforce the requirements declared by the underlying repository Previously, `hg log -r 'bundle()' -R bundle.hg` was failing for me when run from source, complaining about an unknown parent, when the system installed `hg` didn't. Some debugging showed the index was 0 length. It turned out that I didn't have the C extensions compiled, which a simple `hg log -r .` was able to indicate. The problem being that the RequirementError got handled by RepoError, which uses an empty directory as a fallback to process the bundle.

scmutil: make checknewlabel() allow "_" in otherwise numeric names (issue6737)

rust-narrow: fix loop that never loops This was caught by `clippy`. I guess the narrow tests leave something to be desired, since this previously only checked the first valid pattern.

hghave: refactor checks for pygments versions using checkvers()

hghave: make different has_pyoxidizer functions have different names There are 3 of them, and them all having the same name triggered code checkers.

tests: pygments 2.14+ highlight whitespace in python code

tests: make sure pygments can detect python script without extension This .t file was failing for me when running run-tests.py with python3.11. Then I tried to run it with python3.10 and it failed anyway, even though it's the default python3 interpreter. But with `python3 ./run-tests.py` it worked fine. And this is what I found while looking at the way pygments lexer checks if a file without extension is likely to be a python script: shebang_matches(text, r'pythonw?(3(\.\d)?)?') Take guess why it doesn't work for python >= 3.10. To work around this issue, we can simply hardcode an "easier" shebang for pygments. This path to python interpreter obviously doesn't need to be accurate, since we're not running this script.

convert: brz 3.3.0 moved NoSuchFile exception to breezy.transport

revset: the `random` sort should not depend on sys.maxsize (issue6770)

contrib: adjust heptapod CI flavor sizes Our CI currently runs on a number of different runners, some of which are run by Clever Cloud. By setting this environement variable, we're asking for a smaller size runner for our smaller jobs, which puts less load on the Clever Cloud infrastructure, while not affecting our overall pipeline times.

resourceutil: start using importlib.resources.files() when possible This avoids DeprecationWarnings related to our use of resources.open_binary() on Python 3.11.

tests: fix a typo in test-demandimport.t I guess we figured out why it wasn't lazy.

tests: os module is frozen in Python 3.11 (issue6786)

convert: replace repr() by pycompat.byterepr() in cvsps.py (issue6789)

convert: change socket mode from b'r+' to 'rwb' in cvs.py (issue6789) 'r+' mode used to open sockets for read/write operations, but '+' is not supported in Python 3. We're using bytes with these sockets everywhere, so the mode should have 'b'. But the mode argument has to be str, not bytes.

convert: turn the last str regex into bytes in cvs.py (issue6789) Since root is bytes, the regular expression should also be bytes.

convert: stop passing str to the dateutil API in darcs I'm sure there's a bunch more stuff in here that's broken, but this was flagged by pytype.

sparse: fix a py2 based usage of `map()` In a local pytype run, this fixes: File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 386, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '0: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]' File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 387, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '1: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]' File "/mnt/c/Users/Matt/hg/hgext/sparse.py", line 388, in debugsparse: unsupported operand type(s) for item retrieval: 'fcounts: Iterator[int]' and '2: int' [unsupported-operands] No attribute '__getitem__' on 'fcounts: Iterator[int]'

histedit: byteify the help for the multifold action While there's some allowance for str in `_()`, it's commented to be for "goofy unicode docstrings in test", so no idea how well that works, but it should at least come back as bytes. With HGPLAIN, however, the str isn't touched and is returned as-is, so this seems like a real bug.

filemerge: fix crash when using filesets in [partial-merge-tools] Without this patch, you'd get `mercurial.error.ProgrammingError: fileset expression with no context`.

packaging: add dependencies to the PyOxidizer build on macOS Otherwise, we get a bunch of test failures for missing things like pygments, or tests skipped entirely. The input file is a copy/paste from the equivalent Windows file, but with dulwich, pygit2, and pytest-vcr commented out because the build process errors out with them, flagging them as incompatible with loading from memory. I have no idea if that's actually true or not, because I've noticed that if I don't `make clean` after every build, the next build flags the watchman stuff as incompatible with loading from memory. The remaining failures are: Failed test-alias.t: output changed Failed test-basic.t: output changed Failed test-check-help.t: output changed Failed test-commit-interactive.t: output changed Failed test-extension.t: output changed Failed test-help.t: output changed Failed test-i18n.t: output changed Failed test-log.t: output changed Failed test-qrecord.t: output changed Failed test-share-safe.t: output changed Most of the issues seem related to loading help for disabled extensions from `hgext.__index__`, namely the full extension help being unavailable, not being able to resolve what commands are provided by what extension, and not having the command level help available. test-log.t, test-commit-interactive.t, and test-i18n.t look like i18n (or lack thereof) issues. test-basic.t is just odd: @@ -55,7 +55,7 @@ On Python 3, stdio may be None: $ hg debuguiprompt --config ui.interactive=true 0<&- - abort: Bad file descriptor (no-rhg !) + abort: response expected abort: response expected (rhg !)

tests: conditionalize path output for in-memory pyoxidizer resources

tests: conditionalize test output for in-filesystem pyoxidizer resources The in-memory pyoxidizer builds apparently behave as expected.

hghave: add predicates for embedded and filesystem pyoxidizer resources There are a handful of tests with different output between the two flavors of pyoxidizer builds (like the location of the modules and templates), and a few others that avoid `known-bad-output` cases with the embedded resources that shouldn't cause the tests to fail.

run-tests: support --pyoxidized on macOS We should definitely be able to test this before releasing it with an installer.

make: add a target for building pyoxidizer tests on macOS The resources seem to be embedded inside the binary, but for some reasons they aren't read there. And since they are embedded, they aren't staged by the build in the `lib` directory like on Windows. So copy them from the repo. We can figure out what's going wrong later.

copyright: update to 2023

bisect: correct message about aborting an in-progress bisect (issue6527) By using a custom cmdhint message here we're avoiding automatic hint generation in _statecheck.hint(), which would suggest 'hg bisect --continue' and 'hg bisect --abort' (neither of which is a valid option). This patch is only fixing the message about in-progress bisect, it doesn't modify the unfinished state checking logic.

tests: document what the other currently enabled pylint check ensures

hghave: detect newer pylint Older versions (e.g. 2.7.2) say: "Usage: pylint [options]" Newer versions (e.g. 2.15.5) say: "usage: pylint [options]"

emitrevision: consider ancestors revision to emit as available base This should make more delta base valid. This notably affects: * case where we skipped some parent with empty delta to directly delta against an ancestors * case where an intermediate snapshots is stored. This change means we could sent largish intermediate snapshots over the wire. However this is actually a sub goal here. Sending snapshots over the wire means the client have a high odd of simply storing the pre-computed delta instead of doing a lengthy process that will… end up doing the same intermediate snapshot. In addition the overall size of snapshot (or any level) is "only" some or the overall delta size. (0.17% for my mercurial clone, 20% for my clone of Mozilla try). So Sending them other the wire is unlikely to change large impact on the bandwidth used. If we decide that minimising the bandwidth is an explicit goal, we should introduce new logic to filter-out snapshot as delta. The current code has no notion explicite of snapshot so far, they just tended to fall into the wobbly filtering options. In some cases, this patch can yield large improvement to the bundling time: ### data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog # benchmark.name = perf-bundle # benchmark.variants.revs = last-100000 before: 68.787066 seconds after: 47.552677 seconds (-30.87%) That translate to large improvement to the pull time : ### data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog # benchmark.name = pull # benchmark.variants.issue6528 = disabled # benchmark.variants.revs = last-100000 before: 142.186625 seconds after: 75.897745 seconds (-46.62%) No significant negative impact have been observed.

sqlitestore: add an `ancestors` method We will need it during bundling. The implementation mirror the one in revlog.

emitrevision: if we need to compute a delta on the fly, try p1 or p2 first Falling back to `prev` does not yield any real value on modern storage and result in pathological changes to be created on the other side. Doing a delta against a parent will likely be smaller (helping the network) and will be safer to apply on the client (helping future pulls by Triggering intermediate snapshop where they will be needed by later deltas).

emitrevision: simplify the fallback to computed delta Not using the stored delta, or having a full snapshot on disk behave the same ways, so lets use the same code path for that, this is simpler, and it update will be simpler.

emitrevision: also check the parents in the availability closure One of the point of having a closure is to gather the logic in it. So we gather the logic. The `parents[:]` part is a bit ugly but will be replaced by better code soon anyway.

emitrevision: add a small closure to check if a base is usable We will make more use of this and make it more complex too.

chg: scale the timeout in test with the rest This should avoid some flakiness where the logs reports server shutting down.

hghave: we might need py310 and py311 at some point Some tests are already showing slightly different results on Python 3.11. The better idea would be to make them more portable, but if that's not possible, now we can use hghave detection for certain lines. I wonder if there will ever be Python 31.0 and 31.1 though.

hghave: detect Python 3.10 and 3.11 as well Noticed because test-contrib-relnotes.t was skipped.

extensions: load help from hgext.__index__ as a fallback this time Prior to 843418dc0b1b, `hgext.__index__` was consulted first if present, which caused the longer help from the extension modules to be ignored, even when available. But that change causes a bunch of test failures when the pyoxidized binary bundles *.pyc in the binary, saying the there's no help topic for `hg help $disabled_extension` and suggesting the use of `--keyword`, rather than showing a summary and indicating that it is disabled. Current failures were in test-check-help.t, test-extension.t, test-help.t, and test-qrecord.t. Ideally, we would read the various *.pyc files from memory and slurp in the docstring, but I know that they used to not be readable as resources, and I can't figure out how to make it work now. So maybe 3.9 and/or the current PyOxidizer doesn't support it yet. I got closer in py2exe with `importlib.resources.open_binary("hgext", "rebase.pyc")`, but `open_binary()` on *.pyc fails in pyoxidizer.[1] Either way, the *.pyc can't be passed to `ast.parse()` as `extensions._disabledcmdtable()` is doing, so I'm setting that aside for now. [1] https://github.com/indygreg/PyOxidizer/issues/649

extensions: process disabled external paths when `hgext` package is in-memory This fixes `hg help -e ambiguous` in test-helpt.t:2055 with the `ambiguous = !./ambiguous.py` configuration, when `hgext` is not in the filesystem (e.g. pyoxidizer builds with in-memory resources, or TortoiseHg with py2exe), but the disabled external extension is. Now instead of aborting with a suggestion to try `--keyword`, the help command prints text for the extension.

hg: show the correct message when cloning an LFS repo with extension disabled The `extensions._disabledpaths()` doesn't handle fetching help from `__index__`, so it returns an empty dictionary of paths. That means None is always returned from `extensions.disabled_help()` when embedding resources inside the pyoxidizer or py2exe binary, regardless of the arg or if is an external extension stored in the filesystem. And that means wrongly telling the user with an explicitly disabled LFS extension that it will be enabled locally upon cloning from an LFS remote. That causes test-lfs-serve.t:295 to fail. This effectively reverts most of the rest of 843418dc0b1b, while keeping the help text change in place (which was specifically identified as a problem).

demandimport: fix a crash in LazyFinder.__delattr__ I was tinkering with `with hgdemandimport.deactivated()` wrapped around loading the keyring module, and got spew that seemed to be confirmed by PyCharm.

tests: use `test -f` instead of `ls` to see if a file is present (issue6662) ls's exit code when file doesn't exist is 2 on Linux and 1 on NetBSD, so let's use something that's supposedly more portable, since we only care whether the file is there or not.

rust-status: fix thread count ceiling This was forcing 16 threads instead of creating a ceiling, which is wrong when either the available parallelism of the platform is lower or when the user wants to set it explicitly (like we do in `run-tests.py`)

tests: use an all too familiar executable in test-run-tests.t (issue6661) true(1) sometimes lives in /usr/bin/, and so this test fails on such systems. We also can't use which(1), because it's apparently not POSIX and Debian complains about it [1]. We also cannot really create a script and chmod +x it, because this is a symlink case, execbit case is slightly below. So let's use something that we know is executable, but not hg itself.

tests: add the missing space to test-hghave.t (issue6762) log() in run-tests.py add a space to the end of all messages that it prints, and I missed this fact in my previous patch.

tests: expect the message from 1baf0fffd82f in test-hghave.t (issue6762) Couldn't reproduce locally, but apparently this message may occasionally pop up when running this test.

test: adjust test-push-race.t timeout's to overall test timeout The generic `tests/testlib/wait-on-file` mechanism scale its timeout with the value of `HGTEST_TIMEOUT`, the `delaypush.py` in `test-push-race.t` is not doing this, and we have been seeing more and more timeout from loaded CI worker lately. Adding this timeout scaling should help with that.

python-compat: adapt to Python 3.11 BC breakage with `random.sample` As per https://docs.python.org/3/whatsnew/3.11.html#porting-to-python-3-11: "The population parameter of `random.sample()` must be a sequence, and automatic conversion of sets to lists is no longer supported. Also, if the sample size is larger than the population size, a `ValueError` is raised"

match: make the FLAG_RE pattern a raw string PyCharm was complaining about invalid escape sequences since this was added recently in 3eda36e9b3d6.

help: fix a py3 error interpolating Set into b'%s' I can't reproduce it, but a coworker hit this with `hg help -v` with 6.2.3: ... File "mercurial\help.pyc", line 865, in helplist TypeError: %b requires a bytes-like object, or an object that implements __bytes__, not 'set' I can confirm that the original expression fails in `hg debugshell`, and the new one works. The second instance was found by searching for "%s", but PyCharm detects a lot of variables as Any type, so I have no idea if there are other lurking problems.

Added signature for changeset c890d8b8bc59

Added tag 6.3.1 for changeset c890d8b8bc59

relnotes: add 6.3.1

memory-usage: fix `hg log --follow --rev R F` space complexity When running `hg log --follow --rev REVS FILES`, the log code will walk the history of all FILES starting from the file revisions that exists in each REVS. Before doing so, it looks if the files actually exists in the target revisions. To do so, it opens the manifest of each revision in REVS to look up if we find the associated items in FILES. Before this changeset this was done in a way that created a changectx for each target revision, keeping them in memory while we look into each file. If the set of REVS is large, this means keeping the manifest for each entry in REVS in memory. That can be large… if REV is in the form `::X`, this can quickly become huge and saturate the memory. We have seen usage allocating 2GB per second until memory runs out. So this changeset invert the two loop so that only one revision is kept in memory during the operation. This solve the memory explosion issue.

tests: run many tests in $TESTTMP/repo instead of $TESTTMP This is useful so we can store other files in $TESTTMP (in particular tests that use docket files (nodemap, dirstate-v2) keep file uids in $TESTTMP/UID)

tests: fix the detection of dirstate-v2 in hghave.py

dirstate-v2: do not put the dirstate data file in a transaction, since the transaction reverts the store, while the dirstate is stored separately

commit: properly consider file include and exclude options when closing branch It looks like this is meant to prevent adding another commit that does nothing but close a branch on top of a commit that already closed the branch. The matcher building functions want `Dict[bytes, Any]`, not `Dict[str, Any]`, which was found by adding type hints to the matcher related methods in scmutil.

tests: demonstrate a bug blocking a redundant branch close

tests: stop creating temporary files in TESTDIR

cffi: fix a bytes vs str issue on macOS when listing directories This code hasn't been touched in recent years, and the other implementation return bytes for the filename, so I assume this is a holdover from the py2 days. I was unable to test it on mac though, because the `_osutil` import failed.

packaging: refresh dependency hashes (issue6750) Also, add some documentation to the `.in` files.

matcher: do not prepend '.*' to pattern using ^ after flags Since the previous commit (fixing wider issue), the code generated strange regex. This is now fixed and tested.

matcher: fix the issue with regex inline-flag in rust oo Same problem same solution.

matcher: fix issues regex flag contained in pattern (issue6759) Python 3.11 is now enforcing that flag must be at the beginning of the regex This creates a serious regression for people using Python 3.11 with an hgignore using flag in a "relre" pattern. We now detect any flags in such pattern and "prepend" our ".*" pattern after them. In addition, we now insert the flag in the regexp to only affect the pattern we are rewriting. Otherwise, the regex built from the combined pattern would these flags in the middle of it anyway. As a side effect of this last change, we fix a bug… before this change regex flag in a pattern would affect all combined patterns. That was bad and is not longer the case. The Rust code needs to be updated to fix that very bug, but we will do it in another changeset.

release: removed the 6.3.0 tag The revision having two tags confuses some of the build script trying to fetch the version. So, remove the "bad" tag for now.

hg-core: relax dependencies pinning Being this rigid makes packagers' job more difficult since they might not carry the exact version. This hard pinning was introduced in eb02decdf but wasn't strictly necessary to achieve its compatibility goal.

tests: make running ls in a no longer existing directory more portable On Linux, ls -A simply returns nothing and the exit code is 0. On NetBSD, ls -A complains that . doesn't exist and the exit code is 1. Sadly, it's not possible to do something like "[1] (?)", so " || true" is the best I could come up with.

tests: move some lines inside #if windows-#else block test-removeemptydirs.t This is done to make it's clear that windows is not affected by this test case, IOW windows and non-windows platforms are now tested separately, because their results are very different.

tests: use ls -A instead of ls -1 in test-removeemptydirs.t In case the tests are run as root, ls assumes -A by default on some systems (e.g. NetBSD). Tests probably shouldn't be run as root, but let's use -A just in case, for convenience.

release: add the "6.3" to the 6.3 release The release was tagged "6.3.0" while the custom have been to omit the third ".0" for initial release for the history of the project. For consistency, we add the customary version of the tag to the 6.3 release.

tests: fix new git protocol policy in convert-git.t Recent versions of git restrict the use of the "file" protocol for security reasons (https://github.com/git/git/commit/a1d4f67). This broke this test, which failed with the following hidden error: "fatal: transport 'file' not allowed". This patch relaxes the git configuration for the test to solve this.

relnotes: add final 6.3 relnotes

rust: create wrapper struct to reduce `regex` contention issues Explanations inline.

tags-fnode-cache: skip building a changectx in getfnode Building a changectx object is costly, doing it just to retrieve the revision number is suboptimal. Directly fetching the revision number from the changelog provide a sizeable speedup to `hg debugupdatecache`. ### data-env-vars.name = mercurial-2018-08-01-zstd-sparse-revlog # benchmark.name = debug-update-cache # benchmark.variants.pre-state = warm before: 0.213229 seconds after: 0.165577 seconds (-22.35%) # data-env-vars.name = mercurial-filtered-2019-11-22-zstd-sparse-revlog before: 1.200383 seconds after: 1.071618 seconds (-10.73%) # data-env-vars.name = mozilla-central-2018-08-01-zstd-sparse-revlog before: 1.465735 seconds after: 0.923128 seconds (-37.02%) # data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog before: 6.511771 seconds after: 4.507316 seconds (-30.78%) # data-env-vars.name = netbeans-2018-08-01-zstd-sparse-revlog before: 1.023007 seconds after: 0.645026 seconds (-36.95%) # data-env-vars.name = pypy-2018-08-01-zstd-sparse-revlog before: 0.381141 seconds after: 0.268654 seconds (-29.51%)

tags-fnode-cache: do not repeatedly open the filelog in a loop While getting multiple hgtagsfnodecache entries, we were opening (and closing) the `.hgtags` filelog for each iteration. The meant repeatedly reading and parsing the version same information from disk. A quite costly operation. We no longer do this, leading to a sizable improvement in `hg debugupdatecache` run for an already warm repositories. ### data-env-vars.name = mercurial-2018-08-01-zstd-sparse-revlog # benchmark.name = debug-update-cache # benchmark.variants.pre-state = warm before: 1.711778 seconds after: 0.213229 seconds (-87.54%) # data-env-vars.name = pypy-2018-08-01-zstd-sparse-revlog before: 4.010817 seconds after: 0.381141 seconds (-90.50%) # data-env-vars.name = netbeans-2018-08-01-zstd-sparse-revlog before: 13.574141 after: 1.023007 seconds (-92.46%) # data-env-vars.name = mozilla-central-2018-08-01-zstd-sparse-revlog before: 18.884656 after: 1.465735 seconds (-92.24%) # data-env-vars.name = mozilla-try-2019-02-18-zstd-sparse-revlog before: 88.924823 after: 6.511771 seconds (-92.68%)

profile: prevent a crash when line number is unknown For some unknown reason, `self.lineno` can be None. The previous code crashed in such case, we now ignore the case, as we do for other error in this function. We also fallback to using `-1` in the output when this lack of line number makes it to the display code. The reason of unknown line-numbers is… unknown.

upgrade: byteify requirement changes written to output ui.write() expects bytes, and internally uses `b''` as the default when getting the `label` keyword from `*args`. So either we're missing test coverage, or there's some very subtle conversion from unicode somewhere. Also, slip in a type hint to flag this in the future.

rhg: add a config option to fall back immediately This is useful for debugging the behavior of the "default" `hg` in tests without having to manually substitute the fallback path.
