Hacking filekäfer

Checkpointing

Thanks to @lusis for the suggestion on a good path for tracking offsets in files as filekäfer reads and processe.

Basically we need to track:

  • Bytes read

  • The inode number of the file

  • Filesize

For cases of a copytruncate, filekäfer can check if the overall filesize is greater than the last read, and if so, assume that the offset in the file has been reset.
