Subject: cli/insert: return EX_TEMPFAIL for some errors
X-Git-Tag: 0.23.4~8
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=d74c5345704136611f993ca38e0d035b1da798b6

cli/insert: return EX_TEMPFAIL for some errors

Attempt to distinguish between errors indicating misconfiguration or
programmer error, which we consider "permanent", in the sense that
automatic retries are unlikely to be useful, and those indicating
transient error conditions. We consider XAPIAN_EXCEPTION transient
because it covers the important special case of locking failure.
