Add socket timeout and ttl support in `sys::redox`
This adds support for `read_timeout`, `write_timeout`, and `ttl` on `TcpStream`, `TcpListener`, and `UdpSocket` in the `sys::redox` module.
The DNS lookup has been set to use a 5 second timeout by default.

rustbuild: Fix a few rebuilding issues
Did a bit of investigation and found a few small unrelated issues, but this should help clean up a lot of errors we've been seeing locally.
|
|
Use more specific panic message for &str slicing errors
Separate out of bounds errors from character boundary errors, and print
more details for character boundary errors.
It reports the first error it finds in:
1. begin out of bounds
2. end out of bounds
3. begin <= end violated
3. begin not char boundary
5. end not char boundary.
Example:
&"abcαβγ"[..4]
thread 'str::test_slice_fail_boundary_1' panicked at 'byte index 4 is not
a char boundary; it is inside 'α' (bytes 3..5) of `abcαβγ`'
Fixes #38052

Recent versions of Cargo lift less output up into the "main" directory, so let's
look more inside the `deps` folder for changes to propagate differences.
Closes #38744
Closes #38746

Despite what the comment says, we actually need to do this. We're not cleaning
out the stage0 compiler's sysroot, but rather just our own sysroot that we
assembled previously.

prefer hyphens in test files named after issue numbers
We have a lot of tests with filenames honoring particular issues by
number. Typically, these are called issue-${issue_no}.rs (note the
hyphen):
```
$ find . -regextype posix-egrep -regex '.*/issue-[0-9]*.rs' | wc
1289 1289 35935
```
We also had a much smaller number of files that are like this, but don't
have a hyphen in between the substring `issue` and the number:
```
$ find . -regextype posix-egrep -regex '.*/issue[0-9]*.rs'
./debuginfo/issue14411.rs
./debuginfo/issue12886.rs
./debuginfo/issue13213.rs
./debuginfo/issue22656.rs
./debuginfo/issue7712.rs
./compile-fail/issue32829.rs
./run-pass/issue24353.rs
./run-pass/issue34796.rs
./run-pass/issue18173.rs
./run-pass/issue22346.rs
./run-pass/auxiliary/issue13507.rs
./run-pass/issue26127.rs
./run-pass/issue22008.rs
./run-pass/issue34569.rs
./run-pass/issue29927.rs
./run-pass/issue36260.rs
```
Some would argue that the inconsistency is æsthetically displeasing,
hence this trivial patch. (Note that run-pass/auxiliary/issue13507.rs
has an excuse; it's `use`d in run-pass/issue-13507-2.rs; the matter of
there being two different compile-fail tests with different name
conventions for issue no. 32829 is also neglected here for the sake of
keeping this trivial cleanup patch as trivial as possible for ease of
review.)

Don't warn about dead foreign items if the 'allow(dead_code)' attribute is present

Reword 'stupid' and 'crazy' in docs.
These terms are not very descriptive and are better reworded as something else.

Fix debuginfo for unsized struct members
The member was given the size of a fat pointer, which caused

Fix pre-cfg_attr notation in comment
Commit aa3b1261b164eeac3e68573bfc698d1ca943fb05 has changed notation
in the test from `#[ignore(cfg(ignorecfg))]` to `#[cfg_attr(ignorecfg, ignore)]`,
but missed to change the comment in the accompanying Makefile.

Stop creating fake HIR pattern nodes.
This replaces all the HIR patterns `rustc_const_eval` creates with the more appropriate HAIR equivalent.
The only place left that creates HIR nodes is the "explicit lifetimes in function signature" suggestion, which only creates type nodes while rebuilding the signature, but that is only in case of an error.

rustbuild: fix dist-analysis with full bootstrap disabled
Really fixes #38734, per discussion in #38752 which was solving the underlying problem the wrong way.
This just mirrors the [similar logic] in documentation building as suggested, that just takes the stage1 compiler artifacts instead in case of non-full-bootstrap builds. Actually copying the artifacts around seems to be unnecessary.
r? @alexcrichton
[similar logic]: https://github.com/rust-lang/rust/blob/7b659cfdbce094a790dbb246da2681a47565782a/src/bootstrap/doc.rs#L140-L144

sparc64-linux support
This is built on top of #38656 and depends on rust-lang/libc#483
Hello world works.
The libc-test test suite passes.
`panic!` doesn't fully work:
```
$ qemu-sparc64-static ./panic
thread 'main' panicked at 'explicit panic', panic.rs:1
note: Run with `RUST_BACKTRACE=1` for a backtrace.
Illegal instruction (core dumped)
```
Backtraces don't work either, probably related to the previous point:
```
$ export RUST_BACKTRACE=1
$ qemu-sparc64-static ./panic
thread 'main' panicked at 'explicit panic', panic.rs:1
stack backtrace:
Illegal instruction (core dumped)
```

Add a DroplessArena and utilize it as a more efficient arena when possible
I will collect performance (probably just `-Ztime-passes`, and more if that shows significant differences, perhaps).
6feba98 also fixes a potential infinite loop if inplace reallocation failed for `TypedArena` (and `DroplessArena` via copied code).

Gate on distcheck on Travis
This commit adds a new entry to the Travis matrix to gate on distcheck, the illustrious test process that has historically taken *8 hours* to complete and also breaks all the time on nightly. By adding it to Travis we should hope to never see nightly breakage (like https://github.com/rust-lang/rust/issues/38690) because of this ever again!
"But wait, surely we can't wait 8 hours for all PRs!" you might be thinking, and you are indeed correct. The distcheck added here is much more optimized for speed than the old buildbot instances for a number of reasons:
* We're not building *two host compilers* beforehand. The current distcheck bot does a cross for i686 Linux and x86_64 Linux before it actually runs distcheck, building 6 compilers and LLVM twice. None of this is done in parallel as well (e.g. `-j1`). Not doing any of this work will be a huge win!
* We're using sccache to compile LLVM, so it should be much faster. Distcheck on the bots didn't cache LLVM well and rebuilt it every time.
All in all, this version of "distcheck" should be exactly like other matrix entries that run tests except that it's a *little* slower to start as it has to create the source tarball then rebuild the build system in the distcheck dir. Overall this should be well under the 2 hours that Android is currently taking anyway.
Closes https://github.com/rust-lang/rust/issues/38691

i128 and u128 support
Brings i128 and u128 support to nightly rust, behind a feature flag. The goal of this PR is to do the bulk of the work for 128 bit integer support. Smaller but just as tricky features needed for stabilisation like 128 bit enum discriminants are left for future PRs.
Rebased version of #37900, which in turn was a rebase + improvement of #35954 . Sadly I couldn't reopen #37900 due to github. There goes my premium position in the homu queue...

cargotest: Add xsv to tested crates
This was intended to land in #37149 but I ended up backing it out to land the
rollup (#38697) last night as I was itching to do so. This morning though xsv
has been fixed now (BurntSushi/xsv#53) so we should be able to add it!

rustbuild: Compile all support tools in stage0
This commit changes all tools and such to get compiled in stage0, not in
later stages. The purpose of this commit is to cut down dependencies on later
stages for future modifications to the build system. Notably we're going to be
adding builders that produce a full suite of cross-compiled artifacts for a
particular host, and that shouldn't compile the `x86_64-unknown-linux-gnu`
compiler more than once. Currently dependencies on, for example, the error index
end up compiling the `x86_64-unknown-linux-gnu` compiler more than necessary.
As a result here we move many dependencies on these tools to being produced by a
stage0 compiler, not a stage1+ compiler. None of these tools actually need to be
staged at all, so they'll exhibit consistent behavior across the stages.

rustbuild: Add more deps on android-copy-libs
The android-copy-libs step is crucial for running tests on the Android target as
it copies necessary scripts and such to the emulator. We must run that before
running any tests there, but we erroneously only did it for compiletest test
suites!
