How to tell which file slows ripgrep down?

[openaphid]

When ripgrep gets stuck, is there a verbose mode to trace which file was the root cause?

You can try the --trace flag.

Another approach is a binary search of sorts. Keep removing things from your search until it gets faster. When it gets faster, check that what you removed makes ripgrep slow. Then repeat.

Sorry for my late reply.

I tried --trace and --debug flags. The additional logs seem not relevant when rg gets stuck.

TRACE|grep_searcher::searcher|crates/searcher/src/searcher/mod.rs:680: Some("PREVIOUS_FILE, not the ongoing file"): searching using generic reader
TRACE|grep_searcher::searcher|crates/searcher/src/searcher/mod.rs:729: generic reader: searching via roll buffer strategy
TRACE|grep_searcher::searcher::core|crates/searcher/src/searcher/core.rs:56: searcher core: will use fast line searcher

It's a large code repo which makes it difficult to do a binary search. I was hoping there is an easy way to spot slow files to add to exclude list.

Thanks for the help. I'll try to understand the code of rg and add logs for this specific case.
