Disable debuginfo when compiling tools
Currently the Cargo binary has jumped from 14M to 34M on the beta channel, which
appears to be due to the fact that we're compiling tools with debug information
inside them. This additionally means that the `rls` binary is 62M right now!
This wasn't an intentional change, so be sure to disable debuginfo when
compiling tools as it's just intended for the standard library and compile for
now.
Use the existing path when removing the prefix fails
This allows the use of out-of-tree paths to be specified. I found this while trying to build with a modified version of `rls-data`, which is currently pointing to a version on crates.io.

Also, it wasn't clear if I needed to add a test for this (or how). I didn't see any tests that took paths into consideration.

This commit knocks out a longstanding FIXME in rustbuild which should correctly
recompile stage0 compiletest and such whenever libstd itself changes. The
solution implemented here was to implement a notion of "order only" dependencies
and then add a new dependency stage for clearing out the tools dir, using
order-only deps to ensure that it happens correctly.
The dependency drawing for tools is a bit wonky now but I think this'll get the
job done.
Closes#39396
This commit enables the `rust-analysis` package to be produced for all targets
that are part of the `dist-*` suite of docker images on Travis. Currently
these packages are showing up with `available = false` in the
`channel-rust-nightly.toml` manifest where we'd prefer to have them show up for
all targets.
Unfortunately rustup isn't handling the `available = false` section well right
now, so this should also inadvertently fix the nightly regression.
Add the RLS as a submodule and build a package out of it
r? @brson (and cc @alexcrichton) Please review closely, I am not at all convinced I've done the right things here. I did run `x.py dist` and it makes an rls package which looks right to my eyes, but I haven't tested on non-linux platforms nor am I really sure what it should look like.
This does not attempt to run tests for the RLS yet.
* Use the right version when building combined installer
* Update dependencies of rls as it depends on rustc and plugins
* Fix build-manifest and the versions it uses for the rls
Only use cargo-vendor if building from git sources
The only time we need to vendor sources is when building from git. If one is
building from a rustc source tarball, everything should already be in place.
This also matters for distros which do offline builds, as they can't install
cargo-vendor this way.
This adds a common `Build::src_is_git` flag, and then uses it in the dist-src
target to decide whether to install or use `cargo-vendor` at all.
Fixes#41042.
Handle symlinks in src/bootstrap/clean.rs (mostly) -- resolves#40860.
In response to #40860
The broken condition can be replicated with:
```shell
export MYARCH=x86_64-apple-darwin && mkdir -p build/$MYARCH/subdir &&
touch build/$MYARCH/subdir/file && ln -s build/$MYARCH/subdir/file
build/$MYARCH/subdir/symlink
```
`src/bootstrap/clean.rs` has a custom implementation of removing a tree
`fn rm_rf` that used `std::path::Path::{is_file, is_dir, exists}` while
recursively deleting directories and files. Unfortunately, `Path`'s
implementation of `is_file()` and `is_dir()` and `exists()` always
unconditionally follow symlinks, which is the exact opposite of standard
implementations of deleting file trees.
It appears that this custom implementation is being used to workaround a
behavior in Windows where the files often get marked as read-only, which
prevents us from simply using something nice and simple like
`std::fs::remove_dir_all`, which properly deletes links instead of
following them.
So it looks like the fix is to use `.symlink_metadata()` to figure out
whether tree items are files/symlinks/directories. The one corner case
this won't cover is if there is a broken symlink in the "root"
`build/$MYARCH` directory, because those initial entries are run through
`Path::canonicalize()`, which panics with broken symlinks. So lets just
never use symlinks in that one directory. :-)
Overhaul Bootstrap (x.py) Command-Line-Parsing & Help Output
While working on #40417, I got frustrated with the behavior of x.py and the bootstrap binary it wraps, so I decided to do something about it. This PR should improve documentation, make the command-line-parsing more flexible, and clean up some of the internals. No command that worked before should stop working. At least that's the theory. :-)
This should resolve at least #40920 and #38373.
Changes:
- No more manual args manipulation -- getopts used everywhere except the one place it's not possible. As a result, options can be in any position, now, even before the subcommand.
- The additional options for test, bench, and dist now appear in the help output.
- No more single-letter variable bindings used internally for large scopes.
- Don't output the time measurement when just invoking `x.py` or explicitly passing `-h` or `--help`
- Logic is now much more linear. We build strings up, and then print them.
- Refer to subcommands as subcommands everywhere (some places we were saying "command")
- Other minor stuff.
@alexcrichton This is my first PR. Do I need to do something specific to request reviewers or anything?

- Don't print 'unknown subcommand' at the top of the help message. The help message now clearly instructs the user to provide a subcommand.
- Clarify the usage line. Subcommand is required. Don't echo invalid input back out in the usage line (what the...???). args renamed to paths, because that's what all the args are referred to elsewhere.
- List the available subcommands immediately following the usage line. It's the one required argument, after all.
- Slightly improve the extra documentation for the build, test, and doc commands.
- Don't print 'Available invocations:' at all. It occurred immediately before 'Available paths:'.
- Clearly state that running with '-h -v' will produce a list of available paths.
rustbuild: Update bootstrap compiler
Now that we've also updated cargo's release process this commit also changes the
download location of Cargo from Cargos archives back to the static.r-l.o
archives. This should ensure that the Cargo download is the exact Cargo paired
with the rustc that we release.

rustbuild: Fix compiler docs again
The docs need to be built with the rustbuild feature so the correct
stability attributes (rustc_private) get applied.
