rust-status: check for '.hg' regardless of file type (issue6300) '.hg' would show up in `hg status` if were a symlink. Differential Revision: https://phab.mercurial-scm.org/D8461

rust: remove extra empty line This is a gratuitous cleanup. Differential Revision: https://phab.mercurial-scm.org/D8460

upgrade: properly filter action depending on planned work The `determineactions` function filters out deficiency that are not scheduled to be fixed by the target repository configuration. However it only did so for requirement we currently support, letting other actions for unsupported requirement through even if the target repo configuration did not request it. As a result the output of the command was easily polluted by experimental feature with no upgrade support. We rework the code to still filter out requirement based action without the faulty filtering. Differential Revision: https://phab.mercurial-scm.org/D8427

nodemap: skip persistent nodemap warming for revlog not using it Before this patch, the usual checking (especially, inline-ess) were not performed when warming the cache through `hg debugupdatecache`. This is now fixed. Differential Revision: https://phab.mercurial-scm.org/D8408

wait-on-file: adjust the timer counter The wait performed in increment of 0.01 second, but the timer was expressed in second. So we did not wait 20s, we waited 0.2 second. Internally we adjust the counter to be expressed in centisecond. This prevent some flackyness in the test. Differential Revision: https://phab.mercurial-scm.org/D8453

packaging: add docutils as dependency The previous commit revealed that attempting to run `python setup.py build_doc` from the packaging virtualenv failed due to missing docutils package. We didn't notice this before because py2exe Windows packaging appears to use a Python from another virtualenv (which does include docutils) to invoke setup.py. I discovered this as part of implementing packaging outside of that virtualenv environment. Differential Revision: https://phab.mercurial-scm.org/D8470

setup: use sysstr() on process output Otherwise we get a str-bytes mismatch on Python 3 if an error occurs. Differential Revision: https://phab.mercurial-scm.org/D8469

automation: install latest Python versions in Linux Staying up to date. Keeping parity with the Windows environment. Differential Revision: https://phab.mercurial-scm.org/D8467

contrib: update to latest Python 2.7, 3.7, and 3.8 We would ideally update the 3.5 and 3.6 versions as well. But Python didn't generate exe installers for newer versions for some reason. Differential Revision: https://phab.mercurial-scm.org/D8466

automation: always use latest Windows AMI The old AMI isn't available any more. We seem to run into this problem every few months. Amazon (or Microsoft) appears to be removing the old AMIs when they are superseded or something. Let's give up on tracking known images and switch the image selection logic to use the latest published image. Differential Revision: https://phab.mercurial-scm.org/D8465

rust-chg: reimplement attach_io operation as async function In short, MessageLoop<Connection> was redesigned as Protocol<Connection>, and the protocol methods no longer consume self. API changes are briefly documented in the following page: https://docs.rs/tokio-hglib/0.3.0/tokio_hglib/struct.Protocol.html Differential Revision: https://phab.mercurial-scm.org/D8442

rust-chg: upgrade to futures-0.3 based libraries And do some trivial fixes: - BytesMut::put_u32_be() -> put_u32() - tokio_process -> tokio::process, CommandExt -> Command, spawn_async() -> spawn(), stdin() -> stdin - tokio_timer::sleep() -> tokio::time::delay_for() Differential Revision: https://phab.mercurial-scm.org/D8441

rust-chg: exclude futures-dependent modules from build and break things It's impractical to upgrade the codebase incrementally since futures 0.1 and 0.3 APIs are fundamentally different. So this patch temporarily excludes futures-dependent modules from the build. These modules will be upgraded and re-enabled one by one. Differential Revision: https://phab.mercurial-scm.org/D8440

tests: stabilize test-log.t on Windows I think this is because Windows doesn't recognize single quote. Other ssh based clones use this clunky style too. Differential Revision: https://phab.mercurial-scm.org/D8459

tests: stabilize test-convert-hg-source.t on Windows This was a missing update in 1b8fd4af3318. Differential Revision: https://phab.mercurial-scm.org/D8458

commit: tell user what to do with .hg/last-message.txt I have always assumed that the message will be reused by the next `hg commit`, but it seems it's just silently dropped on the next commit. Let's try to be more helpful by telling the user that they have to manually tell hg to reuse it. The file will still be lost if the user runs some other operation in between (like a non-in-memory rebase). That will be fixed once we've switched all operations to be in-memory :) I didn't include `$(hg root)/` in the path in the message to the user because that would have made the message too long. Hopefully the user will figure that part out themselves. Differential Revision: https://phab.mercurial-scm.org/D8463

test-check-rust-format: specify --edition=2018 rustfmt doesn't read Cargo.toml unless it's executed by cargo. https://github.com/rust-lang/rustfmt#rusts-editions

Added tag 5.4rc0 for changeset 26ce8e751503

merge default into stable for 5.4 release

templatekw: fix shownames() to check if namespace exists in repo (issue6301) Namespace registration is dynamic, but the corresponding template keyword is registered statically.

wait-on-file: use proper variable in math This seems better and safer to be explicit. Differential Revision: https://phab.mercurial-scm.org/D8426

wait-on-file: don't quote arithmetic argument This is unnecessary and Mac OS X choke on them. Differential Revision: https://phab.mercurial-scm.org/D8425

graft: exit 1 on conflicts, like merge It's more consistent, and makes it nicer to script around hg if you don't have to ignore exit code 255, which is the error code for basically everything in hg. Differential Revision: https://phab.mercurial-scm.org/D8423
