std::io::UnstableFileStat doesn't report the correct number of blocks for files on Linux

Platform: 64-bit Ubuntu 13.10

Symptom: the blocks field of UnstableFileStat of any file is always 8, regardless of the actual file size.

Can you confirm that using the raw stat in C shows the number of blocks changing?

[derekchiang]

@alexcrichton sorry I'm not very familiar with Rust's codebase. How do I confirm this?

[alexcrichton]

Oh I'm just curious what stat from C reports. If the C stat and the rust stat report the same thing, then there's probably no problem here. If they report different things, then there's something that we need to look into.

[derekchiang]

@alexcrichton Yeah C reports the same thing. There is nothing wrong with Rust; I made a mistake :)

Thanks for looking into this!
