branching: merge with stable

persistent-nodemap: avoid writing nodemap for empty revlog The format cannot encode the lack of tip_rev. There is currently nothing known to write such empty nodemap right now, but the change we are preparing on default reveal this issue. So I had rather fix it on stable.

histedit: remove superfluous echo() and endwin() calls (issue6859) ncurses patchlevel 20231111 started returning an error from endwin() if called twice without a intervening screen update. Per Sven Joachim in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1058041#17: "AFAICS, invoking curses.echo() and curses.endwin() is superfluous because curses.wrapper already does that for you, and calling curses.endwin() twice throws an error with the newer ncurses. Removing those two lines should fix the problem."

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

Added signature for changeset 71bd09bebbe3

Added tag 6.6.1 for changeset 71bd09bebbe3

relnotes: add 6.6.1

procutil: move stdin assignment outside of try-finally block There is an stdin variable in the global scope of this module. And in the `finally` block of this try-finally statement we're checking `if stdin is not None`. Let's make sure we don't confuse code check tools into thinking we want to use global stdin by moving this line of code outside of `try`. This was caught by pytype 2023.11.21 on Python 3.11.2.

zeroconf: give inet_aton() str instead of bytes All other uses of this function in this extension are already fixed (i.e. use strings instead of bytes). This was caught by pytype 2023.11.21 on Python 3.11.2.

revlog: avoid wrongly updating the data file location on "divert" If we are in the inline case, we need to align the location of the "data" file with the temporary location of the file (i.e. "00changelog.i.a"). However we should not do that for non-inline case… and before this changeset we had been doing it. In addition `index_file` is already a property taking care of updating the "segment file" filename when needed. So we can simply remove all that code. As a result, code trying to read the diverted data before they were committed ended deeply confused as the "00changelog.i.a" file is nothing like the "00changelog.d" file. However nothing corrupted data as all writing where properly handled outside of the "segment file". In "best" cases this small in-memory corruption of the filename when unnoticed until the transaction was committed or rolled back and in the worse case, some data reading was failing during the transaction and resulted in the transaction to be rolled back. However wrong data never reached the disk, so this bug should be have corrupted any repository. This is not catch by tests because most test use a small repository and therefor an inline revlog. In addition the bug only triggers when a changelog read is done in the following "rare" situation: - after some delayed write - after that data have been written in a "divert" file (i.e. `00.changelog.i.a`) - before transaction commit - outside of a "writing" context The issue was introduced in d83d788590a8

revlog: avoid exposing delayed index entry too widely in non-inline revlog Before this change, the index entry would be seen as "appended" to the data file. It did not hurt too much as there are never accessed for reading, but this was odd. So lets stop doing so.

revlog: add one more assert about state of thing when splitting This assert is currently happy, but it does not hurt to adds it to clarify expected state and catch potential error in the future.

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.

censor: fix things around inlining The temporary revlog cannot go through the inline → split process as this would break at transaction commit. (that might be fixable, but lets keep things simple for now). We introduce a cleaner way to enforce this as the previous one was broken in 6.6 On the way we remove multiple weird, fragile and broken overwrite of revlog attributes and we focus on passing the configuration across. We also had to update the test to actually create a non-inline revlog.

revlog: add a `may_inline` argument to revlog This allow for a clean skipping of the inline feature when needed, for example by censor.

revlog: allow explicit passing of config to revlog This will be useful to fix censor in a later changeset.

censor: show that the `not-inline` → `inline` test is broken The source revlog should not be inlined and it is…

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

perf-tags: fix clear_cache_fnodes to actually clear that cache The function was not doing it what it advertise for a long time. So we fix it and we add a way for the perf extensions to detect broken version.

perf-tags: fix the --clear-fnode-cache-rev code It seems like this code never run?

tests: do not fail tests in a state with uncommitted .py file removal The problem is that [hg locate] lists removed files too. We use [hg files] instead because that does not list removed files.

tests: fill in the Windows pattern for `$EADDRNOTAVAIL$` matching This fixes test-https.t on Windows. It looks like the real error translation is "Cannot assign requested address.", and the message here is the start of a longer description, so I'm not sure why this part is emitted. But it's not worth digging into, as it's evidently the same failure.

tests: avoid a cascading failure on Windows The `identify --debug` command here on Windows emits skip updating dirstate: identity mismatch because of the debug switch, which got captured and added to `.hgtags`, and then hijinx ensued. The point of `--debug` seemed to be to get the long hash, so just do that with templating. I have not idea if the message is indicating a problem- there seems to be many more of them in other tests that are not present on Linux.

phabricator: stringify the argument to `getattr()` This fixes a "TypeError: getattr(): attribute name must be string" crash and subsequent test spew. This likely broke in 18c8c18993f0 and was missed in CI because `pytest-vcr` is missing.
