  • Rust: Box Is a Unique Type
    7 projects | news.ycombinator.com | 2 May 2024
    >While we are many missing language features away from this being the case, the noalias case is also magic descended upon box itself, with no user code ever having access to it.

    I'm not sure why the author thinks there's magic behind Box. Box is not a special case of `noalias`. Run this snippet with miri and you'll see the same issue: https://play.rust-lang.org/?version=stable&mode=debug&editio...

    `Box` _does_ have an expectation that its inner pointer is not aliased to another Box (even if used for readonly operations). See: https://github.com/rust-lang/miri/issues/1800#issuecomment-8...)

  • Bytecode VMs in Surprising Places
    9 projects | news.ycombinator.com | 30 Apr 2024
    Miri [0] is an interpreter for the mid-level intermediate representation (MIR) generated by the Rust compiler. MIR is input for more processing steps of the compiler. However miri also runs MIR directly. This means miri is a VM. Of course it's not a bytecode VM, because MIR is not a bytecode AFAIK. I still think that miri is a interesting example.

    And why does miri exist?

    It is a lot slower. However it can check for some undefined behavior.

  • RFC: Rust Has Provenance
    3 projects | news.ycombinator.com | 31 Jan 2024
    Provenance is a dynamic property of pointer values. The actual underlying rules that a program must follow, even when using raw pointers and `unsafe`, are written in terms of provenance. Miri (https://github.com/rust-lang/miri) represents provenance as an actual value stored alongside each pointer's address, so it can check for violations of these rules.

    Lifetimes are a static approximation of provenance. They are erased after being validated by the borrow checker, and do not exist in Miri or have any impact on what transformations the optimizer may perform. In other words, the provenance rules allow a superset of what the borrow checker allows.

  • Mir: Strongly typed IR to implement fast and lightweight interpreters and JITs

  • Running rustc in a browser

    There has been discussion of doing this with MIRI, which would be easier than all of rustc.

  • I've incidentally created one of the fastest bounded MPSC queue
    8 projects | /r/rust | 26 Jun 2023
    Actually, I've done more advanced tests with MIRI (see https://github.com/rust-lang/miri/issues/2920 for example) which allowed me to fix some issues. I've also made the code compatible with loom, but I didn't found the time yet to write and execute loom tests. That's on the TODO-list, and I need to track it with an issue too.
  • Interested in "secure programming languages", both theory and practice but mostly practice, where do I start?
    2 projects | /r/ProgrammingLanguages | 17 Jun 2023
    He is one of the big brains behind Miri, which is a interpreter that runs on the MIR (compiler representation between human code and asm/machine code) and detects undefined behavior. Super useful tool for language safety, pretty interesting on its own.
  • Formal verification for unsafe code?
    2 projects | /r/rust | 16 Jun 2023
    I would also run your tests in Miri (https://github.com/rust-lang/miri) to try to cover more bases.
