py2exe: add workaround to allow bundling of hgext3rd.* extensions...
py2exe: add workaround to allow bundling of hgext3rd.* extensions py2exe doesn't know how to handle namespace packages *at all*, so it treats them like normal packages. As a result, if we try and bundle hgext3rd.evolve in a py2exe build, it won't work if we install evolve into the virtualenv. In order to work around this, tortoisehg installs hgext3rd.evolve etc into its staged hg directory, since it doesn't use a virtualenv. As a workaround for us, we'll just allow any extra packages users want bundled are part of hg during the pseudo-install phase that py2exe uses. I'm not happy about this, but it *works*. As a sample of how you'd make an MSI with evolve bundled: import os import shutil import subprocess import tempfile def stage_evolve(version): """Stage evolve for inclusion in py2exe binary.""" with tempfile.TemporaryDirectory() as temp: evolve = os.path.join(temp, "evolve") subprocess.check_call([ "hg.exe", "clone", "https://www.mercurial-scm.org/repo/evolve/", "--update", version, evolve, ]) dest = os.path.join('..', 'hgext3rd', 'evolve') if os.path.exists(dest): shutil.rmtree(dest) shutil.copytree(os.path.join(evolve, "hgext3rd", "evolve"), dest) def main(): stage_evolve('tip') print("\0") print("hgext3rd") print("hgext3rd.evolve") print("hgext3rd.evolve.hack") print("hgext3rd.evolve.thirdparty") if __name__ == "__main__": main() is a script you can pass to the wix/build.py as --extra-packages-script, and the resulting .msi will have an hg binary with evolve baked in. users will still need to enable evolve in their hgrc, so you'd probably also want to bundle configs in your msi for an enterprise environment, but that's already easy to do with the support for extra features and wxs files in the wix build process.

Mercurial supports generating standalone "bundle" files that hold repository
data. These "bundles" are typically saved locally and used later or exchanged
between different repositories, possibly on different machines. Example
commands using bundles are :hg:`bundle` and :hg:`unbundle`.
Generation of bundle files is controlled by a "bundle specification"
("bundlespec") string. This string tells the bundle generation process how
to create the bundle.
A "bundlespec" string is composed of the following elements:
type
A string denoting the bundle format to use.
compression
Denotes the compression engine to use compressing the raw bundle data.
parameters
Arbitrary key-value parameters to further control bundle generation.
A "bundlespec" string has the following formats:
<type>
The literal bundle format string is used.
<compression>-<type>
The compression engine and format are delimited by a hyphen (``-``).
Optional parameters follow the ``<type>``. Parameters are URI escaped
``key=value`` pairs. Each pair is delimited by a semicolon (``;``). The
first parameter begins after a ``;`` immediately following the ``<type>``
value.
Available Types
===============
The following bundle <type> strings are available:
v1
Produces a legacy "changegroup" version 1 bundle.
This format is compatible with nearly all Mercurial clients because it is
the oldest. However, it has some limitations, which is why it is no longer
the default for new repositories.
``v1`` bundles can be used with modern repositories using the "generaldelta"
storage format. However, it may take longer to produce the bundle and the
resulting bundle may be significantly larger than a ``v2`` bundle.
``v1`` bundles can only use the ``gzip``, ``bzip2``, and ``none`` compression
formats.
v2
Produces a version 2 bundle.
Version 2 bundles are an extensible format that can store additional
repository data (such as bookmarks and phases information) and they can
store data more efficiently, resulting in smaller bundles.
Version 2 bundles can also use modern compression engines, such as
``zstd``, making them faster to compress and often smaller.
Available Compression Engines
=============================
The following bundle <compression> engines can be used:
.. bundlecompressionmarker
Examples
========
``v2``
Produce a ``v2`` bundle using default options, including compression.
``none-v1``
Produce a ``v1`` bundle with no compression.
``zstd-v2``
Produce a ``v2`` bundle with zstandard compression using default
settings.
``zstd-v1``
This errors because ``zstd`` is not supported for ``v1`` types.
