Mercurial Changelog

What's new in Mercurial 5.2

Nov 28, 2019
  • Backwards Compatibility Changes:
  • * The infinitepush extension is believed to be unused, and will be deleted at the end of 2020 unless users contact [email protected].
  • * 'hg grep' now searches working copy file contents by default. We recognize this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior.
  • API Changes:
  • * 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future.
  • * 'mercurial.hg.updatetotally' is now more thorough about checking its
  • 'updatecheck' keyword argument. Previously invalid values would have used
  • the configured default updatecheck method, but now will raise ValueError.
  • * 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.

New in Mercurial 5.0 (May 27, 2019)

  • ui.relative-paths option for getting relative path output from most commands. This is enabled when ui.tweakdefaults is enabled.
  • expectsize() revset errors out if revset has unexpected number of elements.
  • config() template function for getting a config value.
  • {negrev} template keyword shows the negative revision number. This is convenient because it is usually shorter than the positive number, but note that it is less stable.
  • hg uncommit now has an --allow-dirty-working-copy option.
  • hg shelve now has --keep option, which shelves but also leaves the working directory unchanged.
  • hg diff will now include specified files in subrepos.
  • hg recover now has a --no-verify option
  • Python 3 Support (Beta):
  • Mercurial 5.0 has beta level support for running on Python 3.5, 3.6, and 3.7. The Mercurial distribution itself and all extensions bundled with it should work on these Python versions.
  • To use Mercurial with Python 3, invoke setup.py with a Python 3 interpreter or set the PYTHON variable to a Python 3 interpreter when invoking the Makefile. e.g. python3.7 setup.py install or make install-home PYTHON=python3.7.
  • 3rd party extensions will likely need to be ported to support running on Python 3 and attempts to run many existing extensions with a Python 3 powered Mercurial will result in extension loading failures. See the Python3 page for more.
  • While the Mercurial test suite has a >99% pass rate when running with Python 3.5, 3.6, and 3.7, we anticipate that there are still many Python 3 bugs lingering in Mercurial. Please report Python 3 issues using the instructions at BugTracker.
  • If you package Mercurial or distribute it to users, we do not recommend making Python 3 the default at this time.
  • Python 3 is not yet very well tested on Windows and there are likely several more lingering issues on Windows compared to Linux, macOS, and other UNIX-like platforms.
  • Updated Windows Installers:
  • Windows installer packaging has been transitioned away from ad-hoc processes employed on individual contributors' personal machines to occurring in reproducible infrastructure driven by code in the Mercurial repository itself. This transition should enable Windows packaging and releasing to be more reliable and reproducible.
  • As part of this transition, there are changes to the Windows installers.
  • Inno Setup .exe Installer Changes:
  • Python has been upgraded from 2.7.15 to 2.7.16
  • add_path.exe has been removed and the Inno installer now updates PATH via a Pascal script that is part of the installer
  • The dulwich package has been upgraded from version 0.18.3 to 0.19.11
  • The keyring package has been upgraded to version 18.0.1
  • The pygments package has been upgraded to version 2.3.1
  • The urllib3 package is now included
  • The MSVC Runtime DLLs (msvcm90.dll, msvcp90.dll, and msvcr90.dll) have been upgraded from version 9.0.21022.8 to 9.0.30729.9518
  • Various tcl/tk Python packages are now included (making the Python distribution more complete)
  • The pywin32 package is no longer included (pywin32 has not been required by Mercurial for years)
  • Known issue: the distutils package is broken
  • (x86 only) Python .pyd and .dll extension modules and support libraries are now installed as standalone files instead of bundled in the library.zip file. This behavior is now consistent with 64-bit installers.
  • Other Improvements:
  • Improved color scheme for histedit's curses interface, making it more consistent with the curses hunk selector.
  • Bug Fixes:
  • Histedit's curse interface has improved support for non ascii characters.
  • Backwards Compatibility Changes:
  • color: change color of grep.rev label (BC)
  • commit: if interactive, look elsewhere for whitespace settings (BC)
  • diff: make sure we output stat even when --git is not passed (issue4037) (BC)
  • uncommit: abort if an explicitly given file cannot be uncommitted (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.
  • The 32-bit Windows Inno installers no longer distribute w9xpopen.exe. This should only impact people running Mercurial on Windows 95, 98, or ME.
  • The Windows MSI installers no longer include the Python sphinx package and its various dependencies.
  • The Windows MSI installers no longer include the pywin32 Python package.
  • The Windows MSI installers no longer include the enum and future Python packages.
  • Internal API Changes:
  • add: pass around uipathfn and use instead of m.rel() (API)
  • addremove: pass around uipathfn and use instead of m.uipath() (API)
