failed to open stream: File name too long #4046
Description
Steps to reproduce
- Create file with name that is close to filesystem limit of 255 bytes (say 253 bytes)
- Try to sync the file
Expected behaviour
File is synchronized correctly
Actual behaviour
File is not synchronized correctly because Nextcloud adds .ocTransferId**********.part suffix to the end of the file name and thus exceeds filesystem limit for the file name length.
Additional details
I've got this long file name by synchronization of directory that contains eCryptfs data.
My local filesystem is btrfs, filesystem on server is ext4, both limited by 255 bytes for the filename.
Using completely random controllable filenames during uploading will solve issues like this once and forever.
