uncommit: add flag --allow-dirty-working-copy This adds a flag `--allow-dirty-working-copy` as an alias for the experimental config option `experimental.uncommitondirtydir`. Differential Revision: https://phab.mercurial-scm.org/D6069

uncommit: don't allow dirty working copy with PATH (issue5977) On a dirty PATH, uncommit was working without even setting the config `experimental.uncommitondirtydir` to `True`. Ideally, it should abort as it does for a dirty dir. This patch makes uncommit to require the config option `experimental.uncommitondirtydir` on a dirty PATH.

revlog: preserve `_lazydelta` attribute in `revlog.clone` The attribute was introduce in 688fc33e105d, Yuya Nishihara pointed out that this preservation was missing. This changeset fixes the preservation and make sure we set the attribute according the modes.

localrepo: explicit `_lock` arguments in `lock` The argument for `_lock` are non-trivial, having them passed explicitly makes thing clearer in my opinion. This is a Gratuitous change, I expect it will save me (and others) time in the future.

inno: remove w9xpopen.exe w9xpopen.exe is a utility program shipped with Python <3.4 (https://bugs.python.org/issue14470 tracked its removal). The program was used by subprocess to wrap invoked processes on Windows 95 and 98 or when command.com was used in order to work around a redirect bug. The workaround is only used on ancient Windows versions - versions that we shouldn't see in 2019. While Python 2.7's subprocess module still references w9xpopen.exe, not shipping it shouldn't matter unless we're running an ancient version of Windows. Python will raise an exception if w9xpopen.exe can't be found. It's highly unlikely anyone is using current Mercurial releases on these ancient Windows versions. So remove w9xpopen.exe from the Inno installer. .. bc:: The 32-bit Windows Inno installers no longer distribute w9xpopen.exe. This should only impact people running Mercurial on Windows 95, 98, or ME. Differential Revision: https://phab.mercurial-scm.org/D6068

inno: stop shipping pywin32 Ancient versions of Mercurial relied on pywin32 and I suspect that's why we have this dependency. We also ship the "keyring" package, which has a dependency on "pywin32-ctypes" (providing the "win32ctypes" package). This is a stripped down version of pywin32 that doesn't have as many dependencies. Since we don't have a dependency on pywin32 and since pywin32 is a bit annoying to package, let's get rid of it. With this change, py2exe no longers picks up DLL dependencies on various UCRT DLLs (because we no longer have a .pyd file beloning to pywin32 which was pulling them in). So, we were able to remove code in support of the UCRT DLLs. .. bc:: The Windows Inno installers no longer ship the pywin32 package. This package was being bundled for historical reasons. Mercurial stopped using pywin32 several years ago and the disappearance of this package should not have any meaningful impact. Differential Revision: https://phab.mercurial-scm.org/D6067

inno: script to automate building Inno installer The official Inno installer build process is poorly documented. And attempting to reproduce behavior of the installer uploaded to www.mercurial-scm.org has revealed a number of unexpected behaviors. This commit attempts to improve the state of reproducibility of the Inno installer by introducing a Python script to largely automate the building of the installer. The new script (which must be run from an environment with the Visual C++ environment configured) takes care of producing an Inno installer. When run from a fresh Mercurial source checkout with all the proper system dependencies (the VC++ toolchain, Windows 10 SDK, and Inno tools) installed, it "just works." The script takes care of downloading all the Python dependencies in a secure manner and manages the build environment for you. You don't need any additional config files: just launch the script, pointing it at an existing Python and ISCC binary and it takes care of the rest. The produced installer creates a Mercurial installation with a handful of differences from the existing 4.9 installers (produced by someone else): * add_path.exe is missing (this was removed a few changesets ago) * The set of api-ms-win-core-* DLLs is different (I suspect this is due to me using a different UCRT / Windows version). * kernelbase.dll and msasn1.dll are missing. * There are a different set of .pyc files for dulwich, keyring, and pygments due to us using the latest versions of each. * We include Tcl/Tk DLLs and .pyc files (I'm not sure why these are missing from the existing installers). * We include the urllib3 and win32ctypes packages (which are dependencies of dulwich and pywin32, respectively). I'm not sure why these aren't present in the existing installers. * We include a different set of files for the distutils package. I'm not sure why. But it should be harmless. * We include the docutils package (it is getting picked up as a dependency somehow). I think this is fine. * We include a copy of argparse.pyc. I'm not sure why this was missing from existing installers. * We don't have a copy of sqlite3/dump.pyc. I'm not sure why. The SQLite C extension code only imports this module when conn.iterdump() is called. It should be safe to omit. * We include files in the email.test and test packages. The set of files is small and their presence should be harmless. The new script and support code is written in Python 3 because it is brand new and independent code and I don't believe new Python projects should be using Python 2 in 2019 if they have a choice about it. The readme.txt file has been renamed to readme.rst and overhauled to reflect the existence of build.py. Differential Revision: https://phab.mercurial-scm.org/D6066

setup: exclude some internal UCRT files When attempting to build the Inno installer locally, I was getting several file not found errors when py2exe was crawling DLL dependencies. The missing DLLs appear to be "internal" DLLs used by the Universal C Runtime (UCRT). In many cases, the missing DLLs don't appear to exist on my system at all! Some of the DLLs have version numbers that appear to be N+1 of what the existing version number is. Maybe the "public" UCRT DLLs are probing for version N+1 at load time and py2exe is picking these up? Who knows. This commit adds the non-public UCRT DLLs as found by py2exe on my system to the excluded DLLs set. After this change, I'm able to produce an Inno installer with an appropriate set of DLLs.

setup: include additional packages in py2exe distribution I'm attempting to reproduce the Inno installers on my local machine. As part of auditing differences between installer output, I noticed that the existing Inno installers include various 3rd party packages. There is no mention of this in the build instructions nor on the wiki. This must be something that is done by the installer producer. This commit teaches setup.py to include these 3rd party packages in py2exe's library. After this change, I am able to produce Inno installers that have a nearly identical set of Python modules. It's worth noting that pywin32 is included even though it probably shouldn't be. But including it is necessary in order to achieve parity with existing Inno installers.

setup: define build_doc command Currently, various processes for packaging Mercurial state to manually invoke `make -C doc` in order to generate the documentation. This Makefile merely invokes `gendoc.py` and `runrst` to produce man pages and HTML pages. Not all environments may have the ability to easily run Makefiles. Windows is notably in this set. This commit ports the man page and HTML generation logic from doc/Makefile to setup.py. We introduce a new build_doc command which generates documentation by calling gendoc.py and runrst. The documentation can now be built via pure Python by running `python setup.py build_doc`. We don't implement dependency tracking because IMO it is more effort than it is worth. We could potentially remove the duplicated functionality in doc/Makefile. But I'm not sure what all is depending on it. So I plan to keep it around. # no-check-commit because forced foo_bar function names Differential Revision: https://phab.mercurial-scm.org/D6063

inno: replace add_path.exe with a Pascal script While attempting to build the Inno installer, I was unable to find a copy of add_path.exe from the source site previously listed in the docs. Some quick Googling revealed that achieving this functionality in native Pascal scripts seems to be preferred these days. This commit vendors "Modify Path" (fetched from https://www.legroom.net/software/modpath) and plugs it into our Inno config file per its instructions. The existing Inno installer appears to only modify PATH for the current user (as opposed to at the system level). I've maintained this behavior with Modify Path. Although it would be trivial to change or add checkboxes to control the behavior. I'll leave this as a follow-up. Differential Revision: https://phab.mercurial-scm.org/D6060
