Merge master's RUST_VERSION="nightly" into the macOS Rust job
from bug31859_041.
Drop master's RUST_VERSION="beta", because we only have two
Rust jobs now.
Since Rust on macOS is slow, don't wait for the macOS Rust job to finish.
Instead, split rust into slow rust (macOS) and fast rust (Linux). And
allow the build to finish before slow rust finishes.
Also make sure that we have:
* a Rust build on each platform,
* a Rust build with each compiler, and
* a check on all our Rust builds.
Finally, sort builds: allow fail last, macOS first, slowest first.
Closes 31859 for 0.3.5.
Since Travis macOS has IPv6 support (and Travis Linux does not), chutney
will now run its IPv6 networks as part of Travis CI.
But since chutney is slow, don't wait for the macOS chutney to finish.
(Travis have fixed the duplicate notification bug in fast_finish. So we
can use fast_finish and allow_failure to finish early. Unfortunately,
allow_failure also means we ignore failures in macOS chutney.)
Also make sure that we have:
* a compile on each platform, with each compiler,
* a check on each platform, and
* a check on each compiler.
Finally, sort builds: allow fail last, macOS first, slowest first.
Closes ticket 30860.
Closes ticket 31859 for 0.2.9.
Frequently, when a patch fails, it has failures in several files.
Using the "-k" flag will let us learn all the compilation errors,
not just the first one that the compiler hits.
Based on a patch by rl1987.
The #[global_allocator] attribute is not available in versions prior to
1.28.0, the default-linker-libraries feature requires rust 1.31.0.
Adapt the CI to prevent accidental increases in Rust version by testing
against 1.31.0, beta and nightly.
Previously we had "make check" launched whenever DISTCHECK was
false. Now we'd like to turn it off in a few other circumstances,
like running chutney. Maybe stem too?
Skip test_rebind when the TOR_SKIP_TEST_REBIND environmental variable
is set.
Skip test_rebind on macOS in Travis builds, because it is unreliable
on macOS on Travis.
Fixes bug 30713; bugfix on 0.3.5.1-alpha.
