saving a backup via "bup" to kbfs dir fails

[soulware]

I am attempting to setup bup (https://bup.github.io/) against a BUP_DIR on a kbfs mount at /keybase/private/<username>/bup.

Something is not happy in the bup git internals when attempting to run bup save -

Reading index: 7, done.
Saving: 100.00% (2/2k, 7/7 files), done.    
Traceback (most recent call last): 
  File "/usr/local/Cellar/bup/0.28.1/lib/bup/cmd/bup-save", line 460, in <module>
    w.close()  # must close before we can update the ref
  File "/usr/local/Cellar/bup/0.28.1/lib/bup/bup/git.py", line 790, in close
    return self._end(run_midx=run_midx)
  File "/usr/local/Cellar/bup/0.28.1/lib/bup/bup/git.py", line 776, in _end
    os.fsync(self.parentfd)
OSError: [Errno 5] Input/output error

Is this a known limitation in kbfs?

Hi Simon, can you do a 'keybase log send'?

Sending now.

Do you need the log id? And does this need to be sent to you privately?

No, it can be sent publically, thanks!

Thanks for the report. Huh, it loos like bup tries to run fsync on a directory, which we haven't yet implemented. I'll make sure we have a ticket for t internally. Sorry for the inconvenience!
