an effect of 7ce658d is that we can index messages by UID rather than
content (or more specifically, subject). apart from being cleaner, it
allows duplicated subjects.
on modern systems, this makes it likely to end up on tmpfs, which is a
lot faster and ssd-friendlier.
the symlink is not deleted at the end, to minimize fs churn. that means
it will be dangling after a reboot, which gets fixed in the next run.
the operator was exactly inverted. that means that it actually wouldn't
compile with both older versions (that needed the aliases) and
potentially new versions (that will hide the data members - still not
the case as of 3.2).
amends 8a40554f0.
we failed to reset the box list pointer after freeing it, which would
lead to a crash.
we also failed to reset the listing status, which would lead to
malfunction if we hadn't already crashed.
this inlines imap_cleanup_store(), as there isn't much value in keeping
it. the message list is already freed when disowning the store anyway.
we need to deep-copy the struct hostent data, as otherwise the
concurrent connects will overwrite each other's lookup results.
this is a rather hypothetical fix, as the bug currently affects only
channels connecting two IMAP accounts, and only if the first host's
first address asynchronously fails to connect.
this is relevant only when listing an IMAP Store's contents, as that's
the only place where we aren't imposing the spelling ourselves.
we need to be careful not to treat our own canonical (prefix-stripped
and always slash-delimited) box names like that; codify that in
comments.
this reveals that commit 6f2160f1 may be deemed to have been incorrect -
the TODO item was ambiguous, and could quite possibly have meant this
fix. unsurprisingly, 380ccdd4 re-introduced it with more explicit
wording.
the query is untypical enough to have caused problems with davmail (when
we still used *:*) and mailo.com (until it got fixed), so better check
that the result (not) returned by the server makes sense.
we did already set up the timeout when starting to send commands, but so
far we did not reset it when succeeding to send out data. rectify that.

otherwise, we'd re-generate it during 'install' as well.
note that this does not work with new-style git worktrees, where .git is
only a file - but there the log generation itself already doesn't work
anyway.
strptime(3)'s "%d" day of the month conversion specifier does not accept
leading blanks in case of single digit numbers. "%e" does that.
While implementation details and differences between the two
day-of-month conversion specifiers vary, none of the major libcs
(incl. OpenBSD, FreeBSD, Illumos, musl) consume a leading blank for "%d"
except glibc, which consumes any number of spaces like in the "%e" case.
Using "%e" ensures that date strings like " 4-Mar-2018 16:49:25 -0500"
are successfully parsed by all major implementations in compliance to
X/Open Portability Guide Issue 4, Version 2 ("XPG4.2"). musl is now the
only one that still treats "%d" and "%e" without stripping any space.
Issue analysed and reported by Evan Silberman <evan@jklol.net> who found
mbsync 1.3.0 on OpenBSD 6.4 to fail with `CopyArrivalDate' set when
syncing mails with the above mentioned timestamp.
See https://marc.info/?l=openbsd-tech&m=155044284526535 for details.
Ater sasl_client_step() is called and the Cyrus SASL library forwards
it to the client plugin, if the result value is OK (authentication
succeeded), the clientout is filled out to be an empty string, even if
the client plugin wanted to return NULL.
To avoid that mbsync complains at this point, check the returned length
instead of the pointer.
turns out that some IMAP servers (e.g., poczta.o2.pl) do not return
messages in ascending UID order in response to a UID FETCH request,
which makes the driver violate the API contract.
counter this by sorting the messages. this also addresses the
long-standing (but hypothetical) issue that parallel UID FETCH requests
could be handled out-of-order and thus also lead to mixed up results.
based on patch by Marcin Niestroj <macius1990w@gmail.com>.
while only 1KiB is required by the IMAP spec, AUTHENTICATE GSSAPI with
Kerberos requires about 1700 bytes.
accomodate that, plus some reserve.
fix suggested by Tollef Fog Heen <tfheen@err.no> via Debian BTS.
