|Subject:||bug#35139: Rust builds systematically time out|
|Date:||Thu, 4 Apr 2019 08:47:42 -0700|
Rust tests are designed to run in parallel, as long as you have enough
RAM, file descriptors, etc. available on the machine for the amount of
concurrency being used. The compiler test suite is largely just compiling
files, so the most important resource is probably available RAM/swap.
Although that definitely will speed the bootstrap chain, I’m concerned that
if a dependency package ever gets updated and breaks things we wouldn’t
know without running the test suite.
Maybe if the bootstrapped versions don’t ever change skipping the check
phase will be safe, but I think we should try running parallel tests first
and see how far that gets us.
