rustbuild: Implement `make dist` #32237

alexcrichton · 2016-03-13T23:56:44Z

This commit implements the make dist command in the new rustbuild build
system, porting over dist.mk and prepare.mk into Rust. There's a huge amount
of complexity between those two files, not all of which is likely justified, so
the Rust implementation is much smaller.

Currently the implementation still shells out to rust-installer as well as some
python scripts, but ideally we'd rewrite it all in the future to not shell out
and be in Rust proper.

src/bootstrap/build/dist.rs

+    // installed
+    t!(fs::create_dir_all(&overlay));
+    let cp = |file: &str| {
+        t!(fs::copy(build.src.join(file), overlay.join(file)));


So the install script uses the install command all over the place instead of just normal file copies. I'm... not really sure why, but maybe you know @brson? Was it to just explicitly control the permissions? I wouldn't mind adding a little wrapper to this module to do that, but I'm mainly just curious if there are reasons beyond permissions that install is used.

@alexcrichton Just permissions.

And I think this code should change to set the permissions. The installer will actually set them all itself itself during install, but that's a hack because we've historically produced seemingly-broken tarballs that don't retain their permissions. The installer should not be doing that and the permissions should be configured correctly before packaging. Here's the permissions rust-installer expects.

For now this is also rebased on #32206, but the only relevant commit to this PR is the last one.

This commit fixes our support for cross compiling a compiler to run on FreeBSD. Over the weekend I managed to get a cross compiler from Linux to FreeBSD [1] which I hope to soon use to start producing FreeBSD nightly compilers. With the `make dist` support added in rust-lang#32237 we should be able to produce standard rustc/rust-std packages for FreeBSD through a new slave with this cross compiler. Currently, however, we don't "Just Work" when cross compiling FreeBSD and a number of changes were required (part of this PR). They include: * A few build fixes were needed in LLVM. Our own branch has been rebased on the actual 3.8 release and I applied one extra commit [2] which contains two fixes: 1. The LLVM CMake build system passes the `-Wl,-z,defs` flag on many platforms, but *not* when `CMAKE_SYSTEM_NAME` is "FreeBSD". Unfortunately this doesn't take into account when we're cross compiling, and as predicted the build will fail if `-Wl,-z,defs` is passed (see [3] for more info). To fix this we test `TARGET_TRIPLE` instead of the `CMAKE_SYSTEM_NAME` which is what we're compiling for which fixes the problem. 2. The `PATH_MAX` constant is apparently defined in a different location than many other Unix systems, so a file which required this just needed some help to keep compiling. * Support for compiling compiler-rt with CMake has been added to rustbuild. It looks like it just emulates Linux in what it compiles as it didn't seem to naturally produce anything else... At least the architecture is right, so seems good for now at least!

I tried configure --enable-rustbuild --host=arm-unknown-linux-gnueabihf --enable-dist-host-only && make && make dist with this PR and rustbuild generated these tarballs:

rust-docs-1.9.0-dev.tar.gz
rust-std-1.9.0-dev-arm-unknown-linux-gnueabihf.tar.gz
rust-std-1.9.0-dev-x86_64-unknown-linux-gnu.tar.gz
rustc-1.9.0-dev-x86_64-unknown-linux-gnu.tar.gz

Note that rustc-arm is missing. @alexcrichton suggested running python bootstrap.py --stage 2 --step dist --host arm-unknown-linux-gnueabihf to generate the missing tarball and I got this error:

$ python ../rust/src/bootstrap/bootstrap.py --stage 2 --step dist --host arm-unknown-linux-gnueabihf

Which seems to indicate that rustbuild is trying to run the rustc ARM binary.

Then @alexcrichton suggested this patch. I applied and after calling make && make dist I got:

(...)

I hope this info helps to debug the problem!

alexcrichton · 2016-03-16T17:52:25Z

Ok, I've pushed a commit which I believe fixes that problem. I... am not entirely sure how it fixes it but it seems to work locally.

alexcrichton · 2016-03-16T18:32:19Z

Confirmed to work:

rust-buildbot expects that as part of dist the docs will be copied to dist/doc/$CFG_PACKAGE_VERS. This is where the docs are uploaded from, and also critically how rust-buildbot figures out the name of the package being built!

brson · 2016-03-16T21:02:38Z

src/bootstrap/build/dist.rs

+    cp("LICENSE-MIT");
+    cp("README.md");
+    // tiny morsel of metadata is used by rust-packaging
+    let version = &build.version;


I think this value is incorrect. It should be something like rustc 1.9.0-nightly (c66d2380a 2016-03-15), exactly what rustc prints for --version.

Oh looks like I actually managed to accomodate for this!

re-r? @brson

Added an install function which sets permissions and also added the doc directory to make dist.
