Revert "Revert submission"

2019-12-02T23:14:27+00:00

This reverts commit 44c5ab22cbf6332d56d38764131595c4f0fc52cc.

* /dev/kvm does not exist on some test machines,
  so we do not add {kvm,kvm_sys}/TEST_MAPPING files.
* Previous errors of not finding test binary under relative_install_path
  in a sandbox should have been fixed by c/1172431.

Add rust_test modules and TEST_MAPPING.

2019-11-18T05:38:02+00:00

* Temporarily append "[workspace]" to Cargo.toml and
  then run "cargo2android.py --tests --run".
* Manually add defaults to limit build host.
* Manually add TEST_MAPPING to select all rust_test modules.
* libsys_util depends on libcap in src/capabilities.rs,
  but not specified in Cargo.toml. Generated Android.bp
  needs post-editing to add libcap to link.

Add crosvm_defaults with only supported platforms.

2019-11-15T16:16:19+00:00

Adds a rust_defaults module that ensures that our crosvm modules are
only built on supported platforms.

Generate Android.bp into subdirectories.

2019-10-15T05:41:39+00:00

* Use a script cargo2android.py to generate Android.bp files
  from cargo build -v output. Cargo.toml and some build.rs
  files were temporarily changed to pass cargo build.
* Missing output are copied from old Android.bp file:
  * Rerun cargo2android.py in:
    ./tempfile ./gpu_display ./gpu_buffer ./gpu_renderer
  * Native code modules are not handled by cargo2android.py:
    * Copy modules from old Android.bp to ./gpu_display
    * Copy attributes of crosvm from old Android.bp to ./Android.bp
    * Copy libhost_cpuid to x86_64/Android.bp

Test: mm in crosvm and other rust directories.

edition: Eliminate blocks superseded by NLL

2019-04-18T00:22:57+00:00

Before the new borrow checker in the 2018 edition, we sometimes used to
have to manually insert curly braced blocks to limit the scope of
borrows. These are no longer needed.

edition: Remove extern crate lines

2019-04-15T09:06:08+00:00

In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:

    extern crate dep;
    use dep::Thing;

we write:

    use dep::Thing;

In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:

    #[macro_use]
    extern crate sys_util;

After:

    use sys_util::{debug, error};

The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.

    extern crate proc_macro;
