setup: configure py2exe config via environment variables The Inno Setup and WiX installers ship a different set of packages with py2exe builds. And there are multiple WiX installer variants (e.g. TortoiseHG). Since there are multiple variants of py2exe configs and they can be defined by entities not in our repository, let's provide a mechanism for setup.py to supplement behavior via environment variables. This is slighly less hacky than a setup.cfg file IMO since the caller doesn't need to worry about mutating global state of the source directory.

packaging: extract py2exe functionality to own module py2exe builds are shared between Inno Setup and WIX. We'll want the logic for performing py2exe builds to be reusable across the code for both installers. This commit extracts the py2exe-specific functionality into its own module. There's definitely room to customize things further. This will be done in future commits, as necessary. (I'm not even sure what customizations WIX will require yet. Presumably a lot.)

packaging: extract python exe info to own function This is generic functionality. We'll need it for WIX. As part of the port, we expose the full version and return the data as a dict. Differential Revision: https://phab.mercurial-scm.org/D6090

packaging: don't use temporary directory We were no longer doing anything with it after extracting virtualenv and py2exe to the build directory. Differential Revision: https://phab.mercurial-scm.org/D6089

packaging: extract virtualenv and py2exe to build directory The build directory is essentially a cache. We can extract the virtualenv and py2exe package sources to this directory. Differential Revision: https://phab.mercurial-scm.org/D6088

packaging: move Inno Setup core logic into a module Aspects of building the Inno Setup and WIX installers are shared. It will make sense for them to share code. Plus, having code in a reusable library (as opposed to a standalone script) is just a better approach. This commit moves the core logic to build the Inno Setup installer into the hgpackaging package. inno/build.py is now a simple frontend script that calls into a module to do the bulk of the work. As part of this change, I also found a typo in build() where it was referencing "iscc" instead of "iscc_exe." Because "iscc" was in the global scope via the only caller, things just happened to work before. Another benefit of always using functions and not putting global code for __main__ in the same file as library code. Differential Revision: https://phab.mercurial-scm.org/D6087

packaging: move find_vc_runtime_files() into hgpackaging.util In preparation for moving the bulk of the Inno Setup code into hgpackaging. Differential Revision: https://phab.mercurial-scm.org/D6086

packaging: move DOWNLOADS dict to hgpackaging.downloads We'll want to keep state in sync between multiple packaging tools. It makes sense to share a central data structure defining downloads. We also change the function to return the downloads entry so callers don't have to access the global DOWNLOADS in the new location. Differential Revision: https://phab.mercurial-scm.org/D6085

packaging: split downloading code into own module As we will introduce more code to support packaging, it will be useful to have download code in its own module. Differential Revision: https://phab.mercurial-scm.org/D6084

packaging: establish hgpackaging package Previously, contrib/packaging behaved as a root to a package directory and we had a "packagingutil" module. As I work more on packaging code, we'll want to have more code shared between different packaging tools. I think it makes sense to have a single package containing multiple modules than multiple top-level modules. This commit establishes an "hgpackaging" package by moving the existing packagingutil code to it. Differential Revision: https://phab.mercurial-scm.org/D6083

phabricator: convert conduit response JSON unicode to bytes inside callconduit Previously the byte conversion was happening piecemeal in callers, and in the case of createdifferentialrevision not at all, leading to UnicodeEncodeErrors when trying to phabsend a commit with a description containing characters not representable in ascii. (issue6040) Remove all the scattered encoding.unitolocal calls and perform it once, inside callconduit, on the entire response dict recursively before returning it, in keeping with the strategy of converting at the earliest opportunity. Convert all keys used on returned object to bytes. Modify the phabsend tests to test this by adding a € to the commit message of alpha. Differential Revision: https://phab.mercurial-scm.org/D6044

transaction: include txnname in the hookargs dictionary There is no reason to not include the txnname alongside the txnid in all case. The python hooks already have them, so aligning the the shell hooks seems it could be useful in the future. (I don't have a strong opinion about this, we can also decide to never align the python and shell hooks and this and I'll drop this patch).

discovery-helper: reflect argument value in the name of the results It is common to create multiple pairs of repositories using different argument values. Recording the argument value in the results names has two main advantages: * It is easy to remember the value used to create a pair, * It get simpler to create multiple pair at the same time from the same source. Previously, running: `./discovery-helper.sh pypy 50 10` would create a `pypy-left` and `pypy-right` repository. Now it will create `pypy-50h-10d-left` and `pypy-50h-10d-right`.

discovery-helper: echo the stripped revsets early Having them printed early make it easy for a user to just grab the generated revset and directly uses them

contrib: move the `discovery-helper.sh` script in`perf-utils` directory The script appeared before the directory. However the directory exists for this kind of script. We move it there.

tests: stabilize test-split.t for Windows It looks like there will be additional problems beyond this trivial fix, but this should make the bot green again.

tests: stabilize test-share.t on Windows PYTHON was not getting mangled for MSYS style paths, and remote was spitting out remote: 'C' is not recognized as an internal or external command, remote: operable program or batch file. (once -q was removed). Additionally, this should fix a failure with py3 because of spaces in the path.

split: add tests which demonstrate the issue5864 Differential Revision: https://phab.mercurial-scm.org/D6057

discovery: clarify why the caching of children is valid Yuya Nishihara pointed out that the code looks wrong without this clarification. (And, unsurprisingly, Yuya is right)

tests: clarify test setup test in test-uncommit.t I assume the "hg uncommit b" is there to prove that the working copy is dirty before we try "hg uncommit --allow-dirty-working-copy b". It seems clearer to put that check just before we run the actual test. Differential Revision: https://phab.mercurial-scm.org/D6078
