unable to remove a file when it's open? #22

Closed proddy closed 3 years ago

proddy commented 3 years ago

With SPIFFS this was valid:

  File root = fs->open("/configdir");
  File file;
  while (file = root.openNextFile()) {
    fs->remove(file.name());
  }

but with LITTLEFS it will throw an error esp_littlefs: Failed to unlink path "/configdir/file.json". Has open FD.

it's easy to circumvent by cloning the path and issuing a file.close() before the remove() but was I just curious whether this is by design?

Yes, it is different. @BrianPugh may elaborate more details on the lower level.

@proddy, see this issue on same subject - it was already discussed. https://github.com/lorol/LITTLEFS/issues/7#issuecomment-722010369 Hope that helps you to find an acceptable solution

ah thanks. I should have browsed the closed issues. It's not a problem, but people using Arduino and thinking they can swap out SPIFFS with LITTLEFS will likely encounter the same issue. Perhaps worth documenting it somewhere. Anyway thanks for following up and great work on the port!
