rust-dirstatemap: add missing @propertycache While investigating a regression on `hg update` performance introduced by the Rust `dirstatemap`, two missing `@propertycache` were identified when comparing against the Python implementation. This adds back the first one, that has no observable impact on behavior. The second one (`nonnormalset`) is going to be more involved, as the caching has to be done from the Rust side of things.

worker: Use buffered input from the pickle stream On Python 3, "pickle.load" will raise an exception ("_pickle.UnpicklingError: pickle data was truncated") when it gets a short read, i.e. it receives fewer bytes than it requested. On our build machine, Mercurial seems to frequently hit this problem while updating a mozilla-central clone iff it gets scheduled in batch mode. It is easy to trigger with: #wipe the workdir rm -rf * hg update null chrt -b 0 hg update default I've also written the following program, which demonstrates the core problem: from __future__ import print_function import io import os import pickle import time obj = {"a": 1, "b": 2} obj_data = pickle.dumps(obj) assert len(obj_data) > 10 rfd, wfd = os.pipe() pid = os.fork() if pid == 0: os.close(rfd) for _ in range(4): time.sleep(0.5) print("First write") os.write(wfd, obj_data[:10]) time.sleep(0.5) print("Second write") os.write(wfd, obj_data[10:]) os._exit(0) try: os.close(wfd) rfile = os.fdopen(rfd, "rb", 0) print("Reading") while True: try: obj_copy = pickle.load(rfile) assert obj == obj_copy except EOFError: break print("Success") finally: os.kill(pid, 15) The program reliably fails with Python 3.8 and succeeds with Python 2.7. Providing the unpickler with a buffered reader fixes the issue, so let "os.fdopen" create one. https://bugzilla.mozilla.org/show_bug.cgi?id=1604486 Differential Revision: https://phab.mercurial-scm.org/D8051

packaging: lowercase the `contrib` and `templates` directories with Inno I have no idea why these (and `contrib/vim`) were leading with uppercase with Inno, but not WiX. It probably doesn't matter too much, but might be a problem with `templates` if the user enabled case sensitivity on NTFS. Differential Revision: https://phab.mercurial-scm.org/D8063

packaging: merge the requirements.txt files for WiX and Inno Now that the content is common, there's no need to have separate files. The content still differs from the non-Windows platforms though. Differential Revision: https://phab.mercurial-scm.org/D8066

packaging: bundle dulwich, keyring, and pywin32-ctypes with WiX too TortoiseHg installs these, which is possibly where they originated (though I would have thought it more likely to be in the WiX installer, given its heritage). When I was working on the TortoiseHg app for Mac (which uses the similar `py2app`), it wasn't possible to use the keyring extension (even externally) without bundling this keyring package into the app. Assuming the same principle applies here, these would enable some common extensions. One of the things that the TortoiseHg packager on macOS does now is it adds the user's local `site-packages` directory to `sys.path`. That would allow the user to install these critical modules in cases like this. But that can probably wait for py3 packaging. The only difference in the installed packages that I see now is WiX also bundles distutils for some reason. I suppose that's not harming anything, so I'm not touching it. The only orphans in the install directories when comparing WiX and Inno now is the Copying.txt vs COPYING.rtf, the two uninstaller files for Inno, and a `Mercurial.url` file in Inno. I have no idea what that is, and it has *.ini syntax with a single field pointing to the Mercurial homepage. Differential Revision: https://phab.mercurial-scm.org/D8062

packaging: bundle the default mercurial.ini template with Inno also This is a step towards converging on the same installer content on Windows. Differential Revision: https://phab.mercurial-scm.org/D8061

packaging: set the FileVersion field in the Inno installer executable Previously, Properties > Details > File version showed "0.0.0.0". This appears to be a longstanding issue, and not part of the refactoring this cycle. Differential Revision: https://phab.mercurial-scm.org/D8060

packaging: move the version normalization function to the util module This will be used with Inno as well. Since this module isn't platform specific, rename to include that this is meant for Windows. (Mac has a different format.) Differential Revision: https://phab.mercurial-scm.org/D8059

resourceutil: account for the non-resource-like file hierarchy under py2exe After 9e367157a990, config files for py2exe were expected to be in C:\Program Files\Mercurial\mercurial\defaultrc because of the implied resource structure of 'mercurial.defaultrc.*.rc', relative to the executable. Accomodating this would require changes to the WIX and Inno scripts (and perhaps the script that generates the WIX script), as well as 3rd party bundlers like TortoiseHg. But these files aren't read as resources anyway- they fall back to the filesystem APIs. (If we really wanted to carry on the charade, the installer would have to also sprinkle various empty __init__.py files around.) Instead, this simply prunes the 'mercurial.' portion of the resource name when run with py2exe. (PyOxidizer uses the resources API, not the filesystem fallback, so it is unaffected.) Since this hack only affects the py2 Windows installers and is less risky, I think it's reasonable. We haven't needed to load any 3rd party resource up to this point, and would have to make packaging changes anyway to handle that. Differential Revision: https://phab.mercurial-scm.org/D8058

wix: restore COPYING.rtf This got truncated to 0 bytes in 0ab651b5f77c when the Phabricator extension crashed because it's a binary file. That caused the license page in the WIX installer to be empty. I don't remember if I needed to resubmit after the bug was fixed, so let's try this again with the current stable. If this fails, I'll retry with 5.1 to see if this is a regression in the API changeover last cycle. Differential Revision: https://phab.mercurial-scm.org/D8052

resourceutil: correct the root path for file based lookup under py2exe This silly copy/paste error caused "Mercurial" to be truncated from "C:\Program Files". The fact that "helptext" and "defaultrc" are now in a subpackage of "mercurial" added it back on, and everything seemed to work. But that broke if not installed to the default directory, and also caused TortoiseHg to look at Mercurial's config files instead of its own.

wix: use original version string for MSI filename Version string normalization is mostly to placate MSI requirements. I think it makes sense to use the original version string in filenames. Since we can have distinct versions normalizing to the same MSI version string, this will allow us to distinguish between different actual version strings based on the filename. Differential Revision: https://phab.mercurial-scm.org/D8005

wix: always normalize version string Before, it was possible to pass in a custom version string which would not be valid in MSI. So we always normalize the version string. While we're here, also print when we normalize the version string, for better visibility. Differential Revision: https://phab.mercurial-scm.org/D8004

wix: more robust normalization of RC version components MSI has strict version requirements where the format is `A.B.C[.D]` and all fields must be numeric (https://docs.microsoft.com/en-us/windows/win32/msi/productversion?redirectedfrom=MSDN). Only the first 3 are used by the installer itself. Mercurial's version strings can have `rcN` and an optional `+<commit>-<date>` fragment at the end. This commit teaches the MSI version normalization to handle both of these more robustly. Before, we would throw away the `.rcN` component completely. e.g. `5.3rc1` would get normalized to `5.3.0`. And worse, `5.3rc0+5-abcdef` would get normalized to `5.3.5`. After this commit, presence of an `.rcN` provides the value for a 4th field. e.g. `5.3rc1` -> `5.3.0.1`. In addition, the commit count from the `+` suffix gets normalized into the 4th version component, but only if the original version string didn't have a 4th version component or if no `rcN` is present. e.g. `5.3+5-abcdef` is `5.3.0.5`.
