Display correct filename with --test option
Fixes #39592.
With the current files:
```rust
pub mod foo;
/// This is a Foo;
///
/// ```
/// println!("baaaaaar");
/// ```
pub struct Foo;
/// This is a Bar;
///
/// ```
/// println!("fooooo");
/// ```
pub struct Bar;
```
```rust
// note the whitespaces
/// ```
/// println!("foo");
/// ```
pub fn foo() {}
```
It displays:
```
./build/x86_64-apple-darwin/stage1/bin/rustdoc --test test.rs
running 3 tests
test test.rs - line 13 ... ok

Delete the makefile build system
This PR deletes the makefile build system in favor of the rustbuild build system. The beta has now been branched so 1.16 will continue to be buildable from the makefiles, but going forward 1.17 will only be buildable with rustbuild.
Rustbuild has been the default build system [since 1.15.0](https://github.com/rust-lang/rust/pull/37817) and the makefiles were [proposed for deletion](https://internals.rust-lang.org/t/proposal-for-promoting-rustbuild-to-official-status/4368) at this time back in November of last year.
And now with the deletion of these makefiles we can start getting those sweet sweet improvements of using crates.io crates in the compiler!

Add support for test suites emulated in QEMU
This commit adds support to the build system to execute test suites that cannot
run natively but can instead run inside of a QEMU emulator. A proof-of-concept
builder was added for the `arm-unknown-linux-gnueabihf` target to show off how
this might work.
In general the architecture is to have a server running inside of the emulator
which a local client connects to. The protocol between the server/client
supports compiling tests on the host and running them on the target inside the
emulator.
Closes #33114

Don't re-run tests in compiletest if all the inputs haven't changed, manage
stamp files in the output directory.
|
|
These are all now no longer needed that we've only got rustbuild in tree.

travis: Gate on some minimal support for incremental compilation.
This commit adds a travis job that
1. builds a stage2 compiler in incremental mode (but with empty incremental compilation cache), and
2. builds and runs the run-pass test suite also in incremental mode.
Building incrementally with an empty cache makes sure that the compiler doesn't crash in dependency tracking during bootstrapping. Executing the incrementally built test suite gives some measure of confidence that we generate valid code.
Note, however, that the above does not give strong guarantees about the validity of incremental compilation, it just provides a basis for being able to rely on from-scratch incr. comp. builds as reference values in further tests (which then do actual incremental compilation).

Local testing showed that I was able to reproduce an error where debuginfo tests
on Android would fail with "connection reset by peer". Further investigation
turned out that the gdb tests are android with bit of process management:
* First an `adb forward` command is run to ensure that the host's port 5039 is
the same as the emulator's.
* Next an `adb shell` command is run to execute the `gdbserver` executable
inside the emulator. This gdb server will attach to port 5039 and listen for
remote gdb debugging sessions.
* Finally, we run `gdb` on the host (not in the emulator) and then connect to
this gdb server to send it commands.
The problem was happening when the host's gdb was failing to connect to the
remote gdbserver running inside the emulator. The previous test for this was
that after `adb shell` executed we'd sleep for a second and then attempt to make
a TCP connection to port 5039. If successful we'd run gdb and on failure we'd
sleep again.
It turns out, however, that as soon as we've executed `adb forward` all TCP
connections to 5039 will succeed. This means that we would only ever sleep for
at most one second, and if this wasn't enough time we'd just fail later because
we would assume that gdbserver had started but it may not have done so yet.
This commit fixes these issues by removing the TCP connection to test if
gdbserver is ready to go. Instead we read the stdout of the process and wait for
it to print that it's listening at which point we start running gdb. I've found
that locally at least I was unable to reproduce the failure after these changes.
Closes #38710

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.

appveyor: Attempt to debug flaky test runs
This commit is an attempt to debug #38620 since we're unable to reproduce it
locally. It follows the [advice] of those with AppVeyor to use the `handle.exe`
tool to try to debug what processes have a handle to the file open.
This won't be guaranteed to actually help us, but hopefully it'll diagnose
something at some point?

On Android we only have one test thread for supposed problems with concurrency
and the remote debugger. Not all of our suites require one concurrency, however,
and suites like compile-fail or pretty can be much faster if they're
parallelized on Travis.
This commit only sets the test threads to one on Android for suites which
actually run code, and other suites aren't tampered with.

A tweak was made to dependencies in #38451 but the makefiles weren't updated to
accompany this. Instead of trying to integerate the `build_helper` crate into
the makefiles (which currently isn't present) this commit takes the approach of
just duplicating the required logic, which should be small enough for now.

adaptation to rustbuild for openbsd
Since the switch to rustbuild, the build for openbsd is broken:
- [X] `ar` inference based on compiler name is wrong (OpenBSD usually use `egcc`, but `ear` doesn't exist)
- [X] `make` isn't GNU-make under OpenBSD (and others BSD platforms)
- [x] `stdc++` isn't the right stdc++ library to link with (it should be `estdc++`)
- [x] corrects tests that don't pass anymore (problems related to rustbuild)

A more verbose matching failure for mir tests
This makes it easier to work with mir test failures during development.
- Show which expected line was not found
- Show full expected output
- Show full actual output
|
|
the diff extends build_helper to provide an function to return the
expected name of GNU-make on the host: "make" or "gmake".
Fixes #38429

This option lists all the tests and benchmarks a binary provides. By default the listing
is sent to stdout, but if --logfile is also specified, it is written there.
If filters are specified, they're applied before the output is emitted.

Filter matching is by substring by default. This makes it impossible
to run a single test if its name is a substring of some other test.
For example, its not possible to run just "mymod::test" with these
tests:
mymod::test
mymod::test1
mymod::test_module::moretests
You could declare by convention that no test has a name that's a
substring of another test, but that's not really practical.
This PR adds the "--exact" flag, to make filter matching exactly
match the complete name.

Most of the Rust community agrees that the vec! macro is clearer when
called using square brackets [] instead of regular brackets (). Most of
these ocurrences are from before macros allowed using different types of
brackets.
There is one left unchanged in a pretty-print test, as the pretty
printer still wants it to have regular brackets.

Add AppVeyor configuration to the repo
We hope to move to AppVeyor in the near future off of Buildbot + EC2. This adds
an `appveyor.yml` configuration file which is ready to run builds on the auto
branch. This is also accompanied with a few minor fixes to the build system and
such to accomodate AppVeyor.
The intention is that we're not switching over to AppVeyor entirely just yet,
but rather we'll watch the builds for a week or so. If everything checks out
then we'll start gating on AppVeyor instead of Buildbot!

As the entry point for building the Rust compiler, a good user experience hinges
on this compiling quickly to get to the meat of the problem. To that end use
`#[cfg]`-specific dependencies to avoid building Windows crates on Unix and drop
the `regex` crate for now which was easily replacable with some string
searching.

Leverage Cargo workspaces in rustbuild
This is a continuation of https://github.com/rust-lang/rust/pull/36032 which implements the change to use `cargo metadata` to learn about the crate graph.
|
|
This involves hacking the code used to run cargo test on various
packages, because it reads Cargo.lock to determine which packages should
be tested. This change implements a blacklist, since that will catch new
crates when they are added in the future.

* Don't spawn two threads for all tests, just one now that `catch_unwind` is
stable.
* Remove usage of the unstable `box` keyword
* Remove usage of the unstable `FnBox` trait
