Detect filesystem loop during walking the projects by weihanglo · Pull Request #10188 · rust-lang/cargo

weihanglo · 2021-12-10T12:46:53Z

Resolves #9528

This PR also adds a new dependency same-file but since it's already a
dependency of cargo-util, so nothing added actually.

Use walkdir to detect filesystem loop and gain performance boost!

Running cargo doc in root after this fix looks like:

root@4145378fddab:/# ./project/target/debug/cargo doc
error: failed to determine package fingerprint for documenting foo v0.1.0 (/)

Caused by:
  failed to determine the most recently modified file in /

Caused by:
  failed to determine list of files in /

Caused by:
  cannot read "/proc/1/cwd"

Caused by:
  filesystem loop detected: `/proc/1/cwd` links to an ancestor `/`

I've tried using walkdir but found it hard to avoid multple calls on fs::metadata. This is the one with minimal changes I can think of at this moment. I notice that in walkdir, it introduces struct Ancestor to avoid slow open file ops on Windows. Should we need to do the same thing?

For removing unnecessary collect for some calls on PathSource::list_files, I found it not simple to convert it into callback/iterator flavor. The list_files_git is more complex . Will find a time to refactor it if possible.

I'm not personally too familiar with walkdir::Ancestor but I think it'd be pretty reasonable to switch Cargo over to using walkdir. I suspect that it'd be nice to offload some of the more nitty-gritty here and getting nice perf wins would also be good.

I've done the walkdir version as well. Generally it looks nicer, but there is one extra call on path.is_dir() for each entries. Not sure what's the impact of the perf (maybe no?).

alexcrichton · 2021-12-14T17:21:57Z

I think the walkdir version actually looks quite good as well. Could the path.is_dir() be replaced with a test on entry.file_type() perhaps?

Use unordered since order of warning differs on each platform.

Since `StripPrefixError` returned from [`Path::strip_prefix`] is just an error with "prefix not found. We can simply return false for it. Also use `Match::is_ignore` instead of manually matching. [`Path::strip_prefix`]: https://doc.rust-lang.org/1.57.0/std/path/struct.Path.html#method.strip_prefix

weihanglo · 2021-12-15T02:33:31Z

Note that the real performance varies from case to case.

entry.file_type().is_dir() works! Thanks for the suggestion.
