Hello list,
So with 10.13 we have now noticed that Mail also uses what I would call
"safe save" feature when sending email, I'm not sure what it is really
called? Versioning? AtomicFile? It is something we have not been able to
unravel for ZFS of yet, but so far we have lived without it. Mail makes
that a bit awkward. We just get a completely-empty email when you click
"send" and sending fails. Clicking Edit-Message then just shows empty
message.
So I'm wondering if I am allowed to know what underlying feature that
mechanism uses. I have for a while tried to pin it down with dtrace,
perhaps VNOP_EXCHANGE, or VNOP_CLONEFILE, or VNOP_COPYFILE, or renamex
(RENAME_SWAP), or ATTR_VOL_DOCUMENT_ID with UF_TRACKED,
HFSIOC_TRANSFER_DOCUMENT_ID, or ... I have checked quite a few other
things...
Dtrace has not given me any clues as to what we are missing. It could
even be my xmas present!
Sincerely,
Lund
