2020-06-20ci: Enable sanitizers on dist-aarch64-linuxTomasz Miąsko-0/+1
2020-06-15Avoid prematurely recording toolstatesMark Rousskov-1/+3
When we're running with dry_run enabled (i.e. all builds do this initially), we're guaranteed to save of a toolstate of TestFail for tools that aren't tested. In practice, we do test tools as well, so for those tools we would initially record them as being TestPass, and then later on re-record the correct state after actually testing them. However, this would not work well if the build failed for whatever reason (e.g. panicking in bootstrap, or as was the case in 73097, clippy failing to test successfully), we would just go on believing that things passed when they in practice did not. This commit also adjusts saving toolstate to never record clippy explicitly (otherwise, it would be recorded when building it); eventually that'll likely move to other tools as well but not yet. This is deemed simpler than checking everywhere we generically save toolstate. We also move clippy out of the "toolstate" no-fail-fast build into a separate x.py invocation; this should no longer be technically required but provides the nice state of letting us check toolstate for all tools and only then check clippy (giving full results on every build).

2020-05-07Auto merge of #71649 - ecstatic-morse:ci-stage0-doc, r=Mark-Simulacrumbors-0/+1
Ensure that `./x.py doc --stage 0 src/libstd` works via CI This was split off from #71645, which recommends that users first try building `libstd` docs with the bootstrap `rustdoc`. This should work in most cases, but will fail if we start using a very recent `rustdoc` feature outside a `#[cfg(not(bootstrap))]`. It would be very nice to guarantee that `./x.py doc --stage 0 src/libstd` works, since it allows documentation changes to be rendered locally without needing to build the compiler. However, it may put too big a burden on `rustdoc` developers who presumably want to dogfood new features.

2020-04-23Enable "full tools" option on ARM dist buildersAlex Crichton-4/+4
This commit switches the `--enable-extended` option on the arm-related dist builders to `--enable-full-tools`. This alias in `config.py` corresponds to enabling a few more options: * `rust.lld = true` - this is the main purpose of this PR, to enable LLD on ARM-related platforms. This means it will effectively unlock compilation of wasm programs from an arm host. * `rust.llvm-tools = true` - it turns out that this option is largely ignored in rustbuild today. This is only read in one location to set some flags for the `llvm-tools` package, but the `llvm-tools` package is already produced on all of these builders. It's predicted that this will have no effect on build times. * `rust.codegen-backends = ['llvm']` - historically this also enabled the emscripten backend, but that has long since been removed. This brings the ARM dist builders in line with the x86_64 dist builders using this flag. The hope is that the extra time spent on CI building LLD will acceptable because it's cached by `sccache`, LLD is a relatively small C++ project, and the dist builders are all clocking well under 3 hours (the slowest of all builders) around 2 hours. There's likely some possible cleanup that can happen with these configure options since it doesn't look like they've aged too too well, but I'm hopeful that possible refactorings, if necessary, could be deferred to future PRs.

2020-04-13Auto merge of #70989 - eddyb:mir-opt-32-pr-ci, r=Mark-Simulacrumbors-1/+18
ci: run mir-opt tests on PR CI also as 32-bit (for `EMIT_MIR_FOR_EACH_BIT_WIDTH`). Background: #69916 and [`src/test/mir-opt/README.md`](https://github.com/rust-lang/rust/blob/master/src/test/mir-opt/README.md): > By default 32 bit and 64 bit targets use the same dump files, which can be problematic in the presence of pointers in constants or other bit width dependent things. In that case you can add > > ``` > // EMIT_MIR_FOR_EACH_BIT_WIDTH > ``` > > to your test, causing separate files to be generated for 32bit and 64bit systems. However, if you change the output of such a test (intentionally or not), or if you add a test and it varies between 32-bit and 64-bit platforms, you have to run this command (for a x64 linux host): `./x.py test --stage 1 --target x86_64-unknown-linux-gnu --target i686-unknown-linux-gnu --bless src/test/mir-opt` Otherwise, bors trying to merge the PR will fail, since we test 32-bit targets there. But we don't on PR CI, which means there's no way the PR author would know (unless they were burnt by this already and know what to look for). This PR resolves that by running `mir-opt` tests for ~~`i686-unknown-linux-gnu`~~, on PR CI. **EDIT**: switched to `armv5te-unknown-linux-gnueabi` to work around LLVM 7 crashes (see https://github.com/rust-lang/compiler-builtins/pull/311#issuecomment-612270089), found during testing. cc @rust-lang/wg-mir-opt @rust-lang/infra

2020-04-10Auto merge of #66605 - GuillaumeGomez:drop-python2, r=Mark-Simulacrumbors-91/+93
Stop explicitly depending on python 2 This PR revises our previous policy of officially only supporting and testing with python 2 in the CI environment to instead test with python 3. It also changes the defaults to python 3 in our various scripts (usually, by way of `python` rather than `python3` to preserve compatibility with systems that do not have a python 3 available). The effect of this is that we expect all new patches to support python 3 (and will test as such). We explicitly also expect that patches support python 2.7 as well -- and test as such, though only on one builder. This is intended as a temporary, though likely long-lived, measure to preserve compatibility while looking towards the future which is likely to be a python 3 only world. We do not at this point set a timeline for when we'll drop support for python 2.7; it's plausible that this is months or years into the future, depending on how quickly the ecosystem drops support and how painful it is for us to maintain that support over time. Closes #65063 (as far as I can tell; please file explicit and separate issues or PRs if not).

Enable rust-lld on dist-x86_64-musl Add rust-lld to rustup llvm-tools-preview on nightly for musl I am using a musl distro on my workstation, with `RUSTFLAGS="-C target-feature=-crt-static"` this works fine. I know that `x86_64-unknown-linux-musl` was originally only meant as a target and not as a host. But most problems have been fixed, and I have fewer problems with `unknown` (rustup) than when I am using `x86_64-alpine-linux-musl` (rust installed by the distro). The only thing I am missing is rust-lld in llvm-tools-preview on nightly. I needed rust-lld for a wasm tutorial. I built rust-lld and tested it with that tutorial, and it worked well. I asked [here](https://users.rust-lang.org/t/enable-rust-lld-on-x86-64-unknown-linux-musl/39851) where to request to enable lld and ended up doing this PR. I compared llvm-tools-preview `nightly-x86_64-unknown-linux-musl` and `nightly-x86_64-unknown-linux-gnu`: only rust-lld is missing in musl. I tested the change using: ```bash ./src/ci/docker/run.sh dist-x86_64-musl ``` And I checked that the resulting rust-lld binary runs.

2019-12-06Add note to src/ci/docker/README.md about multiple docker imagesAaron Hill-0/+7
I spent a while debugging a strage linker error about an outdated `glibc` version, only to discover that it was caused by a stale `obj` directory. It wasn't obviously to be that using the same obj dir with multiple Docker images (for the same target triple) could be a problem. This commit adds a note to the README, which should hopefully be helpful to anyone else who runs into this issue.

Misc CI improvements This PR contains some misc improvements to our CI configuration: * The environment variables for MinGW builders were greatly simplified, with just `CUSTOM_MINGW=1` to tell the install scripts to install the vendored copy. All the others (`MINGW_URL`, `MINGW_DIR`, `MINGW_ARCHIVE` and `MSYS_BITS`) are detected either from the builder name or the environment. * Collecting CPU stats and running the build were moved into scripts. * Toolstate scripts validation was previously a separate step, ran just when `IMAGE=mingw-check`. This moves the validation code inside the actual image. * Vendored copies are now fetched from https://ci-mirrors.rust-lang.org instead of directly from the bucket. r? @alexcrichton
2019-11-12ci: download curl and openssl from s3 for dist-x86_64-linuxPietro Albini-2/+9
CentOS 5 only supports SSLv3 without SNI, and to get newer protocols working we need to download and compile OpenSSL and cURL from our mirror. Because of that, we can't use the CDN, as CloudFront requires TLSv1 with SNI. This commit changes the dist-x86_64-linux image to bypass the CDN for OpenSSL and cURL.
