rust-index: check rindex and cindex return the same get_rev This is a temporary safeguard while we synchronize both indexes.

rust-index: synchronize remove to Rust index Future steps will bring the two indexes further together until we can rip the C index entirely when running Rust code.

rust-index: remove `__setitem__` method from the mixed index This is not defined on the Python or C one, and isn't used anywhere.

rust-index: check equality between rust and cindex for `__len__`

rust-index: synchronize append method We now append to the Rust index just as we do to the C index. Future steps will bring the two indexes further together until we can rip the C index entirely when running Rust code.

rust-revlog: teach the revlog opening code to read the repo options This will become necessary as we start writing revlog data from Rust.

rust-index: pass data down to the Rust index This will allow us to start keeping the Rust index synchronized with the cindex as we gradually implement more and more methods in Rust. This will eventually be removed.

rust-index: add append method This is the first time the Rust index has any notion of mutability. This will be used in a future patch from Python, to start synchronizing the Rust index and the C index.

rust-index: add an abstraction to support bytes added at runtimes In order to support appending data to the Rust index, we need to abstract data access away from the immutable (on-disk) bytes, to seemlessly fetch either from the preexisting data or from the newly added data.

rust-mixed-index: move the mmap keepalive into a function The same code will be used for keeping the new index mmap around.

rust-mixed-index: rename variable to make the next change clearer We're going to add another mmap reference holder, so let's rename this one first.

rust: fix cargo doc for hg-cpython

branching: merge with default We merge with the current children of the bad merge (37b52b938579)

branching: merge with stable This recreates `37b52b938579` right as a `hg branch --rev 5b186ba40001` screwed up the content.

changelog: disallow delayed write on inline changesets Since this will never happens, we can make the situation invalid and to stop to handling the associated the case. This simplify the random access file reading too.

changelog: never inline changelog 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.

test-transaction-safety: glog out irrelevant flag The test is focussing on the inline flag, so we glob out the other to highlight that fact and prevent noise in the future.

test-transaction-safety: perform the test on a filelog This test previously checked the transaction safety of splitting the changelog. The changelog is a special case, with delayed/diverted writes and we will stop inlining it soon. So we keep testing that transaction is safe around inline on another revlog type : a filelog. Minor comestic adjustement will be done in the next changesets.

test: clarify test-parseindex offsets We will make this revlog non-inline, so we clarify the code to make sure it is simple to adjust the test later.

test: use more globing for perf timing Not sure why we kept the number here.

branching: merge with stable

statprof: handle `lineno == None` in more cases This continues the work from 972f3e5c94b8. We saw a crash on line 956 but I updated lots of other places as well.

branching: merge stable into default

add: don't attempt to add back removed files unless explicitly listed This fixes the bug demonstrated by the previous patch.

tests: show failure to `hg add -I` a dir->symlink transition

setup: try a non-pure version of the local Mercurial if the pure fails Things like `zstd` can make the pure version fails.

setup: make debug simpler by adding a `__repr__` to `hgcommand` This help when trying to debug this logic.

rhg: support rhg status --rev --rev

rust: add a utility function to merge ordered fallible iterators Adding a function merge_join_results_by, a version of itertools::merge_join_by that works on "fallible" iterators (iterators that can produce errors)

rhg: refactor hg status, make the display code usable for non-dirstate status

debugformat: speedup the "plain-cl-delta" check Checking every single revision is too slow, let's use a sampling approach.

templatekw: fix inconsistency of diffstat with diff.merge Previously, `-T'{diffstat}'` was giving stats from the diff against p1, regardless of whether `--config diff.merge=yes` is set. This was inconsistent with `log --patch` which is aware of that option.

util: move diff_parent from logcmdutil to diffutil This function will be used outside of the log command (in templatekw, used by hgweb, for which logcmdutil is not available). Let's move this function together with the rest of the diff-related utils instead.

logcmdutil: return structured diffstat data for json

cleanup: drop the `bytes` compatibility for attribute related function We can rely on the builtins directly now.

cleanup: turn `wrapfunction` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: turn `wrappedfunction` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: turn `pathsuboption` deprecation warning into an error We could simply drop the check, but lets raise explicit error instead of suffering strange error in case of misuse.

cleanup: drop deprecated config attribute on the revlog class This code was marked for deletion in the next cycle. We are now in the next cycle.

cleanup: drop `path.pushloc` deprecated since 6.5 This was scheduled for removal, let us remove it.

cleanup: drop `dirstate.is_changing_parent` deprecated since 6.5 This was scheduled for removal, let us remove it.

cleanup: remove some code scheduled to be removed after 5.9 looks like we missed this when cleaning up previous code.

branching: merge stable into default

py3: pass unicode strings to hasattr() throughout I guess we missed these instances because they're not covered by tests.

perf: support --template on perf::phases

debugformat: fix formatting for compression level `bytes(<int>)` gives a very different result as `str(<int>)` and the display of `hg debugformat` have been broken for a while as a result.

tests: tweak chg test to make it fail less often the test apparently sometimes prints the word "start" as a part of profile, so let's no longer match "start": CHGHG=/*/install/bin/hg (glob) + \x1b[90m | 50.0% 0.01s profiling.py: __enter__ line 196: self.start()\x1b[0m (esc) + \x1b[90m | 50.0% 0.01s profiling.py: start line 261: self._profiler.__enter__()\x1b[0m (esc) + \x1b[90m | 50.0% 0.01s profiling.py: statprofile line 125: statprof.start(mechanism=b'...\x1b[0m (esc) + \x1b[90m | 50.0% 0.01s statprof.py: start line 356: state.thread.start()\x1b[0m (esc) + \x1b[90m | 50.0% 0.01s threading.py: start line 852: self._started.wait()\x1b[0m (esc)

cext: fix potential memory leaks of list items appended with PyList_Append Also reduce the duplication in the tricky code that uses PyList_Append by extracting it into a function `pylist_append_owned`.

relnotes: add 6.6.3

tests: fix nondeterministic test failure in test-contrib-perf.t It turns out (not too shockingly!) the kernel sometimes has some work to do, perhaps at the very least context-switching, so asserting the system time is 0.000000 doesn't work.

grep: restore usage of --include/--exclude options The refactor in 4a73df6eb67d accidentally forgot to transform the opts argument for walkopts into a byteskwargs. This resulted in its options being ignored. In particular, the -X/-I pair of options was missing. A simple fix restores its usage. Tests included, of course.

rust-changelog: don't panic on empty file lists

tests: use sha256line.py instead of /dev/random in test-censor.t (issue6858) Sometimes the systems that run our test suite don't have enough entropy and they cannot produce target file of the expected size using /dev/random, which results in test failures. Switching to /dev/urandom would give us way more available data at the cost of it being less "random", but we don't really need to use entropy for this task at all, since we only care if the file size after compression is big enough to not be stored inline in the revlog. So let's use something that we already have used to generate this kind of data in other tests.

tests: make sha256line.py available for all tests This was previously only used in test-revlog-delta-find.t, but it will be useful (and used) in other tests that might need to generate poorly-compressible files.

tests: don't use "status" operand of dd in test-censor.t (issue6858) Some implementations don't have this operand, let's just direct stderr into /dev/null, that's pretty cross-platform. Also specify bs=512 (the default for me), because the default might be different on different systems. Other uses of dd in the tests do specify it, so this is more consistent.
