rust-cpython: import utils::files::* function at module level IIRC, it's common in Rust to call functions with the module prefix. Differential Revision: https://phab.mercurial-scm.org/D7613

py3: send bytes from Rust-created warning patterns Python code expects bytes in both Python 2 and Python 3, so we should send bytes. Differential Revision: https://phab.mercurial-scm.org/D7612

py3: pass bytes to `configint` and `configbool` Both functions require bytes, even in Python 3. Differential Revision: https://phab.mercurial-scm.org/D7611

rust-threads: force Rayon to respect the worker count in config As per the inline comment, this is a workaround because Rust code does not yet know how to read config files. Differential Revision: https://phab.mercurial-scm.org/D7610

rust-dirs: handle forgotten `Result`s In 1fe2e574616e I introduced a temporary bugfix to align Rust code with a new behavior from C/Python and forgot about a few `Result`s (cargo's compiler cache does not re-emit warnings on cached modules). This fixes it. For the record, I am still unsure that this behavior change is a good idea. Note: I was already quite unhappy with the setters and getters for the `DirstateMap` and, indirectly, `Dirs`, and this only further reinforces my feelings. I hope we can one day fix that situation at the type level; Georges Racinet and I were just talking about devising a POC for using the builder pattern in the context of FFI with Python, we'll see what comes out of it.

status: outputting structured unfinished-operation information This adds a new item in the json/template output for morestatus and added item types to all entries. Differential Revision: https://phab.mercurial-scm.org/D7595

chg: fix chg to work with py3.7+ "coercing" the locale When the environment is empty (specifically: it doesn't contain LC_ALL, LC_CTYPE, or LANG), Python will "coerce" the locale environment variables to be a UTF-8 capable one. It sets LC_CTYPE in the environment, and this breaks chg, since chg operates by: - start hg, using whatever environment the user has when chg starts - hg stores a hash of this "original" environment, but python has already set LC_CTYPE even though the user doesn't have it in their environment - chg calls setenv over the commandserver. This clears the environment inside of hg and sets it to be exactly what the environment in chg is (without LC_CTYPE). - chg calls validate to ensure that the environment hg is using (after the setenv call) is the one that the chg process has - if not, it is assumed the user changed their environment and we should use a different server. This will *never* be true in this situation because LC_CTYPE was removed. Differential Revision: https://phab.mercurial-scm.org/D7550

fuzz: add support for fuzzing under either Python 2 or 3 This was more of a hairball than I hoped, but it appears to work. The hg-py3 branch of my oss-fuzz fork on github has the remaining changes to switch us to Python 3, but we may as well retain Python 2 fuzzing support for at least a little while.
