rust-nodemap-docket: make unaware of `Repo` Differential Revision: https://phab.mercurial-scm.org/D12545

rust-nodemap-docket: move check of nodemap requirement to caller I think it's cleaner if `NodeMapDocket` doesn't know about the `Repo` type. That makes it more easily reusable and testable. This patch moves out one of the uses of `Repo` out of it. Differential Revision: https://phab.mercurial-scm.org/D12544

contrib: update python dependencies on Windows Differential Revision: https://phab.mercurial-scm.org/D12559

contrib: add a hint if the Windows dependency MSI is already installed In the past, I've gotten confused when the script failed on seemingly random python installs (and thus the py3.8 install was commented out from the last time this happened to me, which has been reverted here). This particular error code means the package was already installed. For python, it means the major and minor version are the same, but the micro version may differ. In practice, ignoring the python installation failure will cause the pip installation that happens next to fail, because python.exe for that version is somewhere else on the system. This could probably be fixed by running py.exe with the major and minor version, but that is skipped during the install for some reason. I didn't feel like over complicating this though, and at least there's a better hint when the problem occurs. Differential Revision: https://phab.mercurial-scm.org/D12560

packaging: fix the type hint on the download_entry function Flagged by PyCharm. Differential Revision: https://phab.mercurial-scm.org/D12571

packaging: drop python27 references from the Windows instructions I also diffed these two files and eliminated cosmetic differences to make it easier to ensure both are in alignment. Differential Revision: https://phab.mercurial-scm.org/D12570

git: un-byteify the `mode` argument for the builtin `open()` I guess this was assuming `pycompat.open` was imported, but it's not here or elsewhere in the git extension. Differential Revision: https://phab.mercurial-scm.org/D12568

git: adapt to some recent dirstate API changes There are still old methods like add() and drop(). I don't see anything that looks equivalent, so there's likely more work to do. But this allows diff and commit to work again on the simple webpage repo for thg. Differential Revision: https://phab.mercurial-scm.org/D12567

windows: disable pager when packaged with py2exe With Windows and py3, all output that got directed to the pager was lost. It can be worked around by the user piping to `more`, but that's easy to forget, and can be dangerous if `hg diff` or similar incorrectly shows no changes. The problem appears to be the new WindowsConsoleIO in py3.6[1]. We've worked around it with PyOxidizer by setting the `Py_LegacyWindowsStdioFlag` interpreter option, and worked around it with `hg.bat` and `exewrapper.c` by internally setting `PYTHONLEGACYWINDOWSSTDIO=1`. Unfortunately, py2exe doesn't appear to be able to set the interpreter option, and somehow seems to also ignore the environment variable. The latter isn't a good fix anyway, since setting it in the environment would affect other python programs too. We can't install a global config for this because a config closer to the user (e.g. from before pager was turned on by default) can override it.

resourceutil: force filesystem access to resources when using py2exe I don't know why it doesn't work, but it avoids this fatal error on startup: > hg debugshell Traceback (most recent call last): File "hg", line 58, in <module> File "mercurial\dispatch.pyc", line 143, in run File "mercurial\dispatch.pyc", line 232, in dispatch File "mercurial\dispatch.pyc", line 254, in _rundispatch File "mercurial\ui.pyc", line 316, in load File "mercurial\rcutil.pyc", line 98, in rccomponents File "mercurial\rcutil.pyc", line 68, in default_rc_resources File "mercurial\utils\resourceutil.pyc", line 102, in contents File "<frozen zipimport>", line 775, in contents AssertionError I assume the py2 version of py2exe never hit this because `importlib.resources` failed to import.

setup: fix the py2exe logic to work with py3 TortoiseHg still uses (the modernized) py2exe packaging, but the build was failing since `py2exe.Distribution` was removed. One thing to note is that later in this module, there's a hack to include `distutils` when building from a virtualenv. While `import distutils` works in `hg debugshell` when built with py2, it doesn't work in py3. I'm not sure why- I don't see it in `library.zip` either. It doesn't seem to break anything though.

absorb: make `--edit-lines` imply `--apply-changes` One of our users tried to use `hg absorb -e` but it seemed that it would only bring up the editor if there were no changes the command could automatically detect destination for. I spent probably half an hour debugging why it worked that way. I finally figured out that it does bring up the editor, but you have to answer "yes" to the "apply changes" prompt *first*. That seems very unintuitive. If the user wants to edit the changes, there seems to be little reason to present them with a prompt first, so let's have `-e/--edit-lines` imply `-a/--apply-changes`. All the tests using `-e` also already used `-a`. I changed them to rely on the implied `-a` so we get coverage of that. Differential Revision: https://phab.mercurial-scm.org/D12550

rhg: refactor to pass argv down, instead of caling args_os() This refactoring makes it easy to patch some command-line preprocessing into rhg. We use this to support using rhg as a shebang interpreter, for example. Differential Revision: https://phab.mercurial-scm.org/D12543

rust-revlog: add methods for getting parent revs and entries Differential Revision: https://phab.mercurial-scm.org/D12442

rust-changelog: start parsing changeset data This patch makes `ChangelogRevisionData` do some coarse, line-level splitting of the changeset data into manifest node, user, timestamp, files list, and description. There are no (in-tree) users of these functions yet, but I've added tests to prevent regressions. We'll surely add callers at some point. Differential Revision: https://phab.mercurial-scm.org/D12439

rust-changelog: remove special parsing of empty changelog data for null rev For the null revision, `Revlog::get_rev_data()` will return an empty string (of bytes). We currently handle that case in `ChangelogRevisionData::manifest_node()`. However, it's going to be ugly to have special handling for the null revision for each future method on `ChangelogRevisionData`. This patch therefore restructures the code so we instead initialize the struct with valid data for the null revision. Differential Revision: https://phab.mercurial-scm.org/D12438

rust-changelog: don't skip empty lines when iterating over changeset lines The first empty line in the changeset indicates the end of headers and beginning of description. Callers can't know figure out where that position is if empty lines are skipped. Differential Revision: https://phab.mercurial-scm.org/D12426

rust-requirements: allow loading repos with `bookmarksinstore` requirement `rhg` does support bookmarks, so it can load repos with the `bookmarksinstore` requirement just as well as other repos. Differential Revision: https://phab.mercurial-scm.org/D12425

sslutil: support TLSV1_ALERT_PROTOCOL_VERSION reason code It looks like python 3.10 returns a different reason code on protocol version mismatch. Differential Revision: https://phab.mercurial-scm.org/D12491

test: override default cipher selection when connecting to TLS 1.0/1.1 servers The default set of ciphers on python 3.10 is incompatible with old TLS versions. Differential Revision: https://phab.mercurial-scm.org/D12490

sslutil: be less strict about which ciphers are allowed when using --insecure Python 3.10 restricted which ciphers are enabled by default, leading to no available ciphers for TLS < 1.2. When using the --insecure flag we allow old TLS, so also adjust the cipher list to give connections a chance to work. On the server side, also loosen the cipher selection in tests (when using the devel.serverexactprotocol option). Differential Revision: https://phab.mercurial-scm.org/D12489

sslutil: avoid deprecation warnings from python 3.10's ssl module Use ssl.PROTOCOL_TLS_{CLIENT,SERVER} and SSLContext.{min,max}imum_version when supported (3.7+). And, catch deprecation warnings when the user asks for deprecated TLS versions (1.0 and 1.1). Differential Revision: https://phab.mercurial-scm.org/D12488
