There was a problem hiding this comment.
I think I'd much prefer to see if there's a way to make the walk iterative rather than recursive but this works.
Track the active MemoryProvider recursive readdir traversal path so circular symlinks to directories stop recursing while still listing the symlink entries. Add sync, promise, and withFileTypes coverage. Fixes: nodejs#64148 Signed-off-by: Matteo Collina <hello@matteocollina.com>

MemoryProvider recursive readdir walked the directory tree with a recursive helper. Rewrite it to traverse iteratively with an explicit stack so a deeply nested tree can no longer exhaust the call stack. The set of directories on the active traversal path is still tracked, so a circular symlink stops descending while its entry remains listed; the output and observable behavior are unchanged.

Fixes: #64148
MemoryProvider recursive readdir follows symlinked directories, but circular symlinks could recurse until the stack overflowed. This tracks the active traversal path so cycles are skipped while symlink entries are still listed.
Added regression coverage for sync, promise, mutual-cycle, and withFileTypes recursive readdir cases.
