fix: again allow formatting the working copy while merging I forgot about unfinished merges (I think I was thinking only about unfinished merge conflicts) when I wrote https://phab.mercurial-scm.org/D11209. As a coworker (hg contributor dploch) reported to me, this led to `hg fix --working-dir` failing when you have an uncommitted merge. The fix is trivial: just move the assertion to just before the call to `scmutil.movedirstate()` where it actually matters. Differential Revision: https://phab.mercurial-scm.org/D11376

pyoxidizer: add arch to PyOxidizer MSIs This is the proper filename pattern. This filename format wasn't properly implemented when PyOxidizer took over Python 3 MSI generation in 603efb3845ba. Differential Revision: https://phab.mercurial-scm.org/D11359

pyoxidizer: pass arch to WiXInstaller() We just upgraded Windows automation to PyOxidizer 0.17.0. This version of PyOxidizer changed the behavior of WiX installers so installer architecture defaulted to "x64" (before it defaulted to the target of the pyoxidizer.exe binary). To allow controlling the architecture of the installer, the `arch` argument was added to `WiXInstaller`. This commit passes that argument in. Differential Revision: https://phab.mercurial-scm.org/D11358

contrib: install PyOxidizer 0.17.0 This pulls in some changes we want to improve Windows MSI installers. This will need separate enhancements to the pyoxidizer.bzl. But those will be handled in a separate changeset. Differential Revision: https://phab.mercurial-scm.org/D11357

packaging: reference proper output directory 9438e9b7321a changed the name of the PyOxidizer target, which changed the name of the output directory. The code changed by this patch wasn't properly updated by that changeset. This resulted in a run-time failure due to trying to read from a non-existent directory. This change should fix the building of Python 3 Inno installers. Differential Revision: https://phab.mercurial-scm.org/D11356

packaging: pass extra_pyoxidizer_vars only to pyoxidizer Before, we would attempt to call a function (build_installer_py2exe) that didn't accept this keyword argument. This was preventing the building of py2exe installers. Differential Revision: https://phab.mercurial-scm.org/D11355

hg: don't attempt to extend `sys.path` with the user site without `APPDATA` This variable is created by the system and *should* be available, but test-lfs-bundle.t has a test where it is explicitly unset. It wasn't caught before because prior to 95af358fcdfe, it was limited to the py2exe binary. As a precaution, fix both that and the pyoxidizer case that was causing the test to fail.

branching: merge stable into default

store: return just one filename in walk functions Various walk functions return `(revlog_type, decoded, encoded)` where decoded could be None. But no-one cares about `encoded` and expects `unencoded` to be present, except verify (because this can only happen with old repo formats). Simplify all this by either failing outright if a decoding a filename fails (instead of almost certainly failing with a type error due to treating None as a bytes), or skipping the filename but providing in an out argument for hg verify.

debugrebuildfncache: add a cheaper option to rebuild the fncache On my repository, debugrebuildfncache takes 5-10min with the lock. With the flag added in this commit, it takes 10s. The tradeoff is that it only recovers from certain kinds of corruptions.

wireprotov1peer: update all rpcs to use the new batchable scheme If desired, we could keep the future class and the function that upgrades an old style rpc instead of a new style, for extensions. Differential Revision: https://phab.mercurial-scm.org/D11212

wireprotov1peer: simplify the way batchable rpcs are defined The scheme with futures/generator is confusing due to the way communication is done by side effects, especially with two different "future" objects. Just returning a request and a function to read the response is easier to understand. There are tests failures with the largefiles extension due to it aliasing one rpc to another one, which gets fixed in the next commit. Differential Revision: https://phab.mercurial-scm.org/D11211

clone: properly create target directories during local clone (issue6581) The store encoding was mudding the water. This lead to local clone crashing for file with long filename as their destination directory needed to be encoded. Differential Revision: https://phab.mercurial-scm.org/D11340

clone: add a file demonstrating issue6581 in test-clone-stream.t This is quite noisy so we adds it in its own changeset. Fixes for the issue are coming in the next patch. Differential Revision: https://phab.mercurial-scm.org/D11339

I'm not sure if there's enough info to be able to convert the abort into the wait scenario. As it stands now, we don't support symlinks on Windows, which requires either a UAC Administrator level process or an opt-in in developer mode, and there are several places where the new symlink on Windows support in py3 was explicitly disabled in order to get tests to pass quicker.

pyoxidizer: add user-site to `sys.path` on Windows This is a port of 53221078e0de to Windows to allow pip-installed extensions to be loaded without specifying a path. It's a major headache to have an hg.exe on `PATH` that needs to have the path to the extensions specified, because WSL doesn't see the same path. This is only for Windows for now, to match the currently shipping py2 behavior. There is a better solution with using the `site` package, but this needs support in PyOxidizer[1].

zeroconf: fix an issue concatenating bytes and str `bytes(length)` doesn't do what we want, so use `str`. There appear to be a ton more issues in this extension, including: - globals()[b'_GLOBAL_DONE'] using bytes as the key - `__author__` and similar using bytes - `BadDomainName` is feeding bytes to the Exception constructor - DNSRecord.toString() has the wrong signature (should be str, not bytes) Differential Revision: https://phab.mercurial-scm.org/D11303

revlog: fix more type confusion in index_replace_sidedata_info (issue6580) We were telling python that "rev" was a Py_ssize_t (via the "n" format), but it was actually an int. Differential Revision: https://phab.mercurial-scm.org/D11335

revlog: fix type confusion with sidedata_comp_len (issue6580) The format string uses "i" (int) for sidedata_comp_len, so we shouldn't be passing a pointer to Py_ssize_t to PyArg_ParseTuple. On 64-bit big-endian, this would result in python only writing to the upper 32 bits, and things go downhill from there. Differential Revision: https://phab.mercurial-scm.org/D11334

dirstate: directly call the dirstatemap in `set_untracked` This function is only called in two places: the deprecated "remove" method and in the new `set_untracked` method.

run-tests: introduce a --pyoxidized option This options make it possible to use the pyoxidizer version to run the tests. This is a first basic version that is windows only. The test needs a working python, with Mercurial installed. However the pyoxidizer product is "self contains" without a "usable" Python. There have been discussion to have a fully functional `hg admin::python` command providing a fully functional python interpreter, but nothing is of the sort is ready yet. In In the meantime we use an hybrid approach, similar to what we do for testing `rhg`. We install a full "normal" Mercurial, but also the pyxodizer product as the official `hg binary`. That way, we use the pyoxidizer version or everything, but test that needs to run python have it available, with a fully functional Mercurial package. This first version is pretty basic (Windows only, no --local, not --with-pyoxidized), but it runs, various bug that we will have to fix. Differential Revision: https://phab.mercurial-scm.org/D11277

contrib: switch the Windows bootstrap environment to py3.9 Use the built in `venv` module instead of `virtualenv` for simplicity, and upgrade to a modern Mercurial that supports py3. One issue here is that `venv` doesn't copy `python3{,Y}.dll` into the `Scripts` subdirectory, so running the `hg.exe` that gets installed immediately fails on a clean system because Python isn't in `PATH`. There is code in `python.exe` to detect when it is in a venv and add the original python install to the DLL lookup path, which we don't do in `hg.exe` yet. The simple workaround for now is to run the `hg` script with `python.exe`. Typically `PYTHONLEGACYWINDOWSSTDIO` must be set in the environment on Windows, but the clone process works without it.

hgwebdir: avoid systematic full garbage collection Forcing a systematic full garbage collection upon each request can serioulsy harm performance. This is reported as https://bz.mercurial-scm.org/show_bug.cgi?id=6075 With this change we're performing the full collection according to a new setting, `experimental.web.full-garbage-collection-rate`. The default value is 1, which doesn't change the behavior and will allow us to test on real use cases. If the value is 0, no full garbage collection occurs. Regardless of the value of the setting, a partial garbage collection still occurs upon each request (not attempting to collect objects from the oldest generation). This should be enough to take care of reference cycles that have been created by the last request (assessment of this requires changing the setting, not to be 1). In my experience chasing memory leaks in Mercurial servers, the full collection never reclaimed any memory, but this is with Python 3 and biased towards small repositories. On the other hand, as explained in the Python developer docs [1], frequent full collections are very harmful in terms of performance if lots of objects survive the collection, and hence stay in the oldest generation. Note that `gc.collect()` is indeed trying to collect the oldest generation [2]. This happens usually in two cases: - unwanted lingering objects (i.e., an actual memory leak that the GC cannot do anything about). Sadly, we have lots of those these days. - desireable long-term objects, typically in caches (not inner caches carried by repositories, which should be collected with them). This is a subject of interest for the Heptapod project. In short, the flat rate that this change still permits is probably a bad idea in most cases, and the default value can be tweaked later on (or even be set to 0) according to experiments in the wild.

This silence the following complains: tests/test-convert-bzr.t:117: imports not lexically sorted: breezy.bzr.bzrdir < sys tests/test-convert-bzr.t:117: stdlib import "breezy.bzr.bzrdir" follows local import: breezy tests/test-convert-bzr-ghosts.t:7: imports not lexically sorted: breezy.bzr.bzrdir < sys tests/test-convert-bzr-ghosts.t:7: stdlib import "breezy.bzr.bzrdir" follows local import: breezy tests/test-convert-bzr-treeroot.t:7: imports not lexically sorted: breezy.bzr.bzrdir < sys tests/test-convert-bzr-treeroot.t:7: stdlib import "breezy.bzr.bzrdir" follows local import: breezy Differential Revision: https://phab.mercurial-scm.org/D11249

remotefilelog: fix what looks like a wrong refactoring when various store functions started returning a revlog type as the first element of the tuple. Differential Revision: https://phab.mercurial-scm.org/D11243

rust-nodemap: falling back to C impl as mitigation This is a mitigation for https://bz.mercurial-scm.org/show_bug.cgi?id=6554 We see sometimes almost all data except the most recent revisions removed from the persistent nodemap, but we don't know how to reproduce yet. This has sadly repercussions beyond just needing to reconstruct the persistent nodemap: for instance, this automatically filters out all bookmarks pointing to revisions that the nodemap cannot resolve. If such filtering happens in a transaction, the update of the bookmarks file that happens at the end of transaction loses all bookmarks that have been affected. There may be similar consequences for other data. So this is a data loss, something that we have to prevent as soon as possible. As a mitigation measure, we will now fallback to the C implementation in case nodemap lookups failed. This will add some latency, e.g., in discovery, yet less than disabling the persistent nodemap entirely. We considered implementing the fallback directly on the Python side, but `revlog.get_rev()` is not systematically used, there are also several direct calls to the index method (`self.index.rev()` for a `revlog` instance). It is therefore more direct to implement the mitigation in the rust-cpython wrapper. Differential Revision: https://phab.mercurial-scm.org/D11238

obsolete: disable other evolution config options if createmarkers is off We used to raise an abort in this case, but recent changes to local clone command (377d8fc20e34) resulted in destrepo both caring about experimental.evolution config options and not initializing extensions. So imagine if you had evolve and allowdivergence enabled in your ~/.hgrc. Local clone stopped working after 377d8fc20e34 because evolve sets experimental.evolution=all, but only on srcrepo, for destrepo the extension is not initialized. It's possible to make local cloning work by initializing extensions for destrepo in some cases, but in other cases (e.g. allowdivergence in ~/.hgrc, evolve extension in original-repo/.hg/hgrc) it would still fail. In a discussion with Pierre-Yves David it was decided to simply force other evolution options to be false if createmarkers is not enabled.

fix: use obsolete.isenabled() to check for experimental.allowdivergence Now that obsolete.isenabled() can also check if divergence is allowed, let's use it for consistency. Other experimental.evolution options are already checked via this function. Differential Revision: https://phab.mercurial-scm.org/D11222
