Problems with self-modifying scripts

[vi]

This hack is supposed to increment on each run:

use std::fs::File;use std::io::Write;fn main(){let c=0;
    let mut v = vec![];
    ::std::io::Read::read_to_end(&mut File::open("q").unwrap(),&mut v).unwrap();
    let mut q = &mut File::create("q").unwrap();
    q.write(&v[..53]).unwrap();
    q.write(format!("{}",c+1).as_bytes()).unwrap();
    q.write(&v[54..]).unwrap();
    println!("{}", c);
}

But it stops incrementing if I run if quickly (without waiting after cargo-script script q):

$ cargo-script script q
    Finished release [optimized] target(s) in 0.0 secs
0
$ cargo-script script q 2> /dev/null
1
$ cargo-script script q 2> /dev/null
2
$ cargo-script script q 2> /dev/null
3
$ cargo-script script q 2> /dev/null
4
$ cargo-script script q 2> /dev/null
5
$ cargo-script script q 2> /dev/null
5
$ cargo-script script q 2> /dev/null
5
$ cargo-script script q 2> /dev/null
5
$ cargo-script script q 2> /dev/null
5

Although self-modifying scripts are no priority for cargo-script, this may indicate some issue with caching and lead to stale caches after updating normal scripts.

I've been trying to reproduce this, but I just can't observe this behaviour.

Part of the caching system involves writing a metadata file to the cache for every script built. This includes the source script's mtime (assuming it wasn't an expression on the command line), and a hash of the input script. If the metadata block computed for an invocation doesn't exactly match the metadata block stored in the cache, it triggers a rebuild of the package.

This rebuild involves rewriting the manifest and the source file. However, to avoid incessant recompiling, it won't touch the files if they haven't changed (it computes and compares hashes of the existing file and the new contents before overwriting). Finally, it invokes Cargo.

About the only way I can see this happening is if Cargo itself decides it doesn't need to rebuild the executable (even if the filesystem has very low-precision mtimes, the hash check should prevent cargo-script from re-using the cached package). However, I can't actually trigger this behaviour.

If you can reliably reproduce this, it might help to run cargo-script with full logging, so I can see what it's actually doing, and which part is deciding not to rebuild. This can be done by running with the RUST_LOG environment variable set to "cargo_script=debug".

If it's Cargo deciding not to build, I'm not sure what I can do that doesn't involve blindly forcing Cargo to always rebuild everything every time, which would rather defeat the point of cargo-script.
