rust: use owned types in `Matcher` This simplifies the code a lot, allows for some refactoring to come. The original code tried to prevent allocations that were already happening anyway beforehand.

hg-cpython: fallback when encountering an unknown matcher At this point in the process, nothing user-visible has happened, it is still safe to fallback. This can happen now that we're going to be using "container matchers" like unionmatcher and intersectionmatcher. This is easier and less error-prone than recursive checking beforehand since only the presence of a transformation case will allow the process to continue.

auto-upgrade: add an option to silence the safe-mismatch message For well tested case, the message can get in the way, so we add a way to disable it.

auto-upgrade: add an option to silence the tracked-hint message For well tested case, the message can get in the way, so we add a way to disable it.

auto-upgrade: add an option to silence the dirstate-v2 message For well tested case, the message can get in the way, so we add a way to disable it.

auto-upgrade: rename a variable to match the actual content This was the result of a copy paste.

auto-upgrade: add an option to silence the share-safe message For well tested case, the message can get in the way, so we add a way to disable it.

auto-upgrade: add a test that will host "quiet" testing We will add options to suppress the message in the coming changeset. The changes will be clearer if the full test is already in place.

bundlespec: check the `obsolescence` value before adding the caps This does not really matters as the logic to decide wether or not adding the part is correct and elsewhere. However this seems like a good idea to align this logic witht he semantic of the option.

bundlespec: handle the presence of obsmarker part This make `hg debugbundle --spec` more informative about extra part in the bundle.

bundlespec: fix the generation of bundlespec for `cg.version` If the value is non-default, we display it.

bundlespec: allow the bundle spec to control the bundle version This makes it possible to create bundle using changelog-v3. The `hg debugbundle --spec` output is borked, but this will be fixed in coming changesets.

bundlespec: do not check for `-` in the params portion of the bundlespec Otherwise bundle parameter with `-` in their names result in a crash.

bundlespec: add processing of some parameter value The boolean option needs to be turned into boolean.

bundlespec: extract the parseparams closure It has no value being a closure. We extract it before modifying it further.

bundlespec: test `no` value for the `obsolescence` parameter This is currently broken, but let us test for it first.

bundlespec: test that parameter overwrite the local config This is currently working, but havint it explicitly tested seems useful.

bundlespec: do not overwrite bundlespec value with the config one This is finally making the `obsolete` bundlespec paramater work.

bundlespec: add a `overwrite` parameter to set_param This will open the way for the configuration value to yield in front of the explicit bundle type.

bundlespec: merge the contentopts and params dictionnary They are content using the same keys. Using differents object for access open the gates for confusion in the code using them (this is already the case). So we start fusing their usages to make the parameters more useful. More work will be needed to make them really useful, but the first step is here: not throwing the value away. However this is still not making the previously introduced test useful because currently, the default config value overwrite the one from the bundlespec. We will fix this in the coming changesets.

bundlespec: test if the "obsolete=" parameter is read Narrator voice: Actually it is not. We will fix it in the next changeset.

bundlespec: fix lack of title in a evolve tests This is a full new test case and should be "flagged" as such.

bundlespec: make the `stream` case less special The handling of the stream case seems fragile (does not account for newer parts and options that will arise) and has special code dedicated to it. To simplify and strengthen things, we make it use the same mechanism as the other options. So we make it less special by making it a special value in the common case.

bundlespec: phase out the `_bundlespeccgversions` mapping The `_bundlespeccgversions` mapping is redundant with the `cg.version` parameter. We move all users to the `cg.version` version and phase out the `_bundlespeccgversions` mapping.

typing: add a missing suppression directive for `msvcrt`

windows: drop some py2 compatibility code The comment was wrong- the exception handler was the py3 case.

windows: prevent bytes from being passed to registry APIs There was a TortoiseHg bug report in this area[1], and from inspection, it looks like passing `b""` as `valname` would fail to convert to unicode. The underlying API allows both `""` and `NULL` to return the default value for the key. [1] https://foss.heptapod.net/mercurial/tortoisehg/thg/-/issues/5803

relnotes: add 6.1.3

cleanup: return directly instead of assigning variable

commit: remove special handling of IOError (actually dead code) In the past, IOError was used to mark a file as removed. The differentiation between OSError and IOError in this place was introduced in e553a425751d, to avoid that “normal” OSErrors / IOErrors accidentally mark files as removed. This weird internal API was removed in 650b5b6e75ed. It seems like that changeset should have removed the differentiation, at least I don’t see any reason for keeping it. On Python 3, OSError and IOError are aliased. Therefore the removed code was actually dead.

py3: catch specific OSError subclasses instead of checking errno On Python 3, the "not a directory" error is mapped to ENOTDIR instead of EINVAL. Therefore, catching the NotADirectoryError subclass is sufficient.

py3: catch specific OSError subclasses instead of checking errno Contrary to the previous changesets in this series, this covers cases where errno was checked for multiple values. EACCES -> PermissionError ENOENT -> FileNotFoundError ENOTDIR -> NotADirectoryError EISDIR -> IsADirectoryError

py3: catch ProcessLookupError instead of checking errno == ESRCH

py3: catch PermissionError instead of checking errno == EPERM

py3: catch PermissionError instead of checking errno == EACCES

py3: catch FileNotFoundError instead of checking errno == ENOENT

py3: catch FileExistsError instead of checking errno == EEXIST

py3: catch BrokenPipeError instead of checking errno == EPIPE

py3: catch ChildProcessError instead of checking errno == ECHILD

py3: remove retry on EINTR errno Since the implementation of PEP 475 (Python 3.5), Python retries system calls failing with EINTR. Therefore we don’t need the logic that retries it in Python code.

py3: stop catching TypeError that was raised on Python 2

py3: use `x.hex()` instead of `pycompat.sysstr(node.hex(x))`

tests: assume that `raw` attribute is present on original socket file object It seems like the original socket file object is always an io.BufferedIO instance. If not, the code will fail and we should try harder to get the socket object (e.g. if the original socket file object is unbuffered, we can get the `_sock` attribute directly from it).

tests: constant-fold a `pycompat.ispy3` in testlib/badserverext.py

tests: remove Python 2 special cases in test-stdio.py

py3: remove dead code to make file descriptors non-inheritable On Python 3, file descriptors are already non-inheritable by default.

py3: remove hack that removed flush argument from print() calls on Python 2

py3: remove long() compatibility code

zeroconf: constant-fold a `pycompat.ispy3` I’ve checked that both bytes and str gets passed as the `name` parameter, so the rest of the condition is still required. Because there aren’t really any tests for the extensions, I didn’t want to refactor it to pass a single type.

py3: remove conditional to import collections.abc.MutableMapping

py3: remove dead code to open file with O_CLOEXEC on Python 2 The O_CLOEXEC flag is passed by default on Python 3.

py3: don’t encode node.bin() argument It accepts str and bytes.

convert: inline Python 3 variant of url2pathname_like_subversion()

py3: constant-fold some `pycompat.ispy3`

py3: use `zip()` instead of trying to use `itertools.izip()`

py3: replace mention of “xrange” in docstring by “range”
