fix: `createWriteStream` failing to create new files in directories #783

Closed dy-dx closed 8 months ago

dy-dx commented 8 months ago

This issue provides most of the context: https://github.com/streamich/unionfs/issues/428

428 suggests just to replace `fs.statSync(path)` with `fs.statSync(dirname(path))`, but that could cause surprising behavior in the case where multiple filesystems include the parent directory.

I've added a regression test for this case: "createWriteStream writes to an existing file even if parent dir exists on an earlier fss"

Fixes #428

dy-dx commented 8 months ago

I've just noticed that unionfs iterates backwards through the this.fss array for most operations, except when using createWriteStream/createReadStream.

This seems like a mistake, and I'll address it in ~this PR as well~.

Addressed in https://github.com/streamich/unionfs/pull/785
