perf-helper: add a small extension with revsets to select repository subset Playing with discovery requires building interesting case. To do this we need revsets to try to generate them. We start with a quite simple one. See documentation for details. Differential Revision: https://phab.mercurial-scm.org/D10221

amend: mark commit obsolete after moving working copy We were doing it this way: 1. move working copy (repo.setparents) 2. add obsmarkers (scmutil.cleanupnodes) 3. fix dirstate (dirstate.normal/drop) Step 1 and 3 are closely related, so let's move them together. It seems safest to create the obsmarkers last. This patch thus makes the order 1, 3, 2. Differential Revision: https://phab.mercurial-scm.org/D10197

pull: allow to specify multiple sources I end up needing that on a regular basis and it turn out to be very simple to implement. See documentation and test for details. Differential Revision: https://phab.mercurial-scm.org/D10159

pull: pre-indent a part of the function We are about to run it in a loop, so lets pre-indent it to clarify the actual change in the next changesets. Differential Revision: https://phab.mercurial-scm.org/D10158

command: clarify `postincoming` return and that return handling The command should return None or a return code. The previous code was returning boolean directly relying on the fact that `True → 1` and `False → 0`. This is a good road to troubles, so lets be explicit about that return.

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
