hg: make `clean` return consistent with the `update` function The function return a boolean and is used as such. Lets be explicit about it. Differential Revision: https://phab.mercurial-scm.org/D10156

tests: rename `test-pull` to `test-pull-network.t` If is mostly about ssh and http interaction so lets avoid confusion with a generic `hg pull` test Differential Revision: https://phab.mercurial-scm.org/D10155

tests: move a test about update in test-pull-update.t Differential Revision: https://phab.mercurial-scm.org/D10154

split: close transaction in the unlikely event of a conflict while rebasing `hg split` *should* never result in conflicts, but in case there are bugs, we should at least commit the transaction so they can continue the rebase. One of our users ran into the regression fixed by D10120. They fixed the conflict and the tried to continue the rebase, but it failed with "abort: cannot continue inconsistent rebase" because the rebase state referred to commits written in a transaction that was never committed. Side note: `hg split` should probably turn off copy tracing to reduce the impact of such bugs, and to speed it up as well. Copies made in the rebased commits should still be respected because `hg rebase` calls `copies.graftcopies()`. Differential Revision: https://phab.mercurial-scm.org/D10164

rust-status: fix issue6456 for the Rust implementation also This implementation is being used by a few people now, so we need it fixed, even though a big rewrite will be coming quite soon. Differential Revision: https://phab.mercurial-scm.org/D10217

ci: Add a job testing with rhg installed as `hg` This significantly increases test coverage of rhg, without duplicating many tests that already exist. The `cargo build` command being remove only compiled a `rhg` executable (as shown by the preceding `cd` command) but since a previous patch `run-tests.py --rhg` now takes care of that.

run-test: install rhg if --rhg is passed Before this, --rhg was only working with --local. Differential Revision: https://phab.mercurial-scm.org/D10195

makefile: add a install option This gives and easy way to install rhg that we can use in `run-test.py` in the next changesets. Differential Revision: https://phab.mercurial-scm.org/D10194

makefile: add a build-rhg option This gives an easy action to build the rhg-binary. This will be useful for the `install-rhg` action in the next changeset. Differential Revision: https://phab.mercurial-scm.org/D10193

makefile: add a install-chg option This is done as a gratuitous improvement on the way to add makefile entry to build and install rhg. It seems saner to have equivalent entry for chg too. Differential Revision: https://phab.mercurial-scm.org/D10192

tests: Disable for rhg remaining tests that fail in that mode These cases are in features not yet implemented by rhg for which triggering a fallback is not practical. Disabling some tests allows us to reach passing CI and catch any future regression in the rest of the tests. Differential Revision: https://phab.mercurial-scm.org/D10190

rhg: Remove `rhg.fallback-executable=hg` default configuration When `rhg.on-unsupported` is configured to `fallback` and an unsupported feature is encountered, the previous default was to look for an `hg` executable in `$PATH`. This default was fragile since it was easy to end up accidentally using an older version of Mercurial installed system-wide, when a local (perhaps patched) installation was intended. Instead, it is now an error to have `rhg.on-unsupported=fallback` without also configuring an explicit path or the fallback executable. Differential Revision: https://phab.mercurial-scm.org/D10189
