27a1935361 fix strftime() format string warning properly
the workaround for -Wformat triggered -Wformat-nonliteral in turn.
so instead go back to using pragmas and add a proper gcc version check.

this also works with clang - mostly for qt-creator's code model, which
is clang-based.

83adb9a39b actually implement maildir_get_uidnext()
the assumption was that this wouldn't be needed, as maildir_store_msg()
reliably delivers a UID. however, if we crash right before the callback
can record that UID, we'd still use OPEN_FIND in the next run, which
requires the saved next UID.

04fc586e75 handle case-insensitivity of IMAP's INBOX
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

d61f462039 Fix CopyArrivalDate on platforms without glibc
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

instead of the pointer.

acfa3a2bbc sort messages from UID FETCH request
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.

c4d7f0189c implement Forwarded flag
maildir supports a 'P' flag which denotes the fact that a message has
been 'passed' on (forwarded, bounced). notmuch syncs this to the
'passed' tag.

Per https://tools.ietf.org/html/rfc5788, IMAP has a user-defined flag
(keyword) '$Forwarded' that is supported by many servers and clients
these days. (Technically, one should check for '$Forwarded' in the
server response.)

Restructure mbsync's flag parser to accept keywords (flags starting with
'$') but still bail out on unknown system flags (flags starting with '\').
Support '$Forwarded' as a first keyword since it maps to maildir's 'P'
and needs to be sorted in between the system flags.

c29eceaeed make map_name() interpret empty strings as "no separator"
empty strings were previously meaningless, and starting with 72c2d695a,
failure to handle them lead to bogus results when the IMAP hierarchy
separator is legitimately empty (when the server genuinely supports none
and none is manually configured). non-null can be asserted more cleanly
than null-or-non-empty, so change the api like that.
incidentally, this also removes the need to work around gcc's bogus

56515abe94 socket: use next addrinfo if opening socket fails
The `socket_connect_one` function previously did an `exit(1)` when
encountering any errors with opening the socket. This would break
connecting to a host where multiple possible addrinfos are returned,
where the leading addrinfos are in fact impossible to connect to. E.g.
with a kernel configured without support for IPv6, the `getaddrinfo`
call may still return a hint containing an IPv6 address alongside
another hint with an IPv4 address. Creating the socket with the IPv6
address, which will cause an error, lead us to exiting early without
even trying remaining hints.

While one can argue that the user should have compiled without HAVE_IPV6
or used an appropriate DNS configuration, we can do better by simply
skipping over the current addrinfo causing an error. To do so, we split
out a new function `socket_connect_next`, which selects the next
available address info and subsequently calls `socket_connect_one`
again. When no hints remain, `sock_connect_one` will error out at that
point.

a0961d6505 delay assignment of TUID when propagating messages
go back to assigning TUIDs only right before actually propagating them.
this avoids spurious "TUID lost" warnings.

bd5fb6fff3 move away from magic UIDs in the sync state
the only legitimate "deviant" UID is zero, meaning "no message". this
can be futher qualified by additional flags in the sync record, rather
than using magic values for the UID. in fact, the zero UID (so far
meaning only "expunged") was already optionally qualifed with "expired".

as a side effect, driver->store_msg() now returns 0 instead of -2 for
unknown UIDs. this was a hack to avoid translating the value later
on, but it made the api horrible, and now it's superflous in the first
place.

4ffe149666 split off ephemeral sync record state to a separate member
this allows us to simplify logging of expiration, as we now can just log
the entire persistent state instead of fiddling with bits.

efd72b85cc autotest: implement much more thorough resumption verification
the test will now make a test run for every journaled step, both right
before and right after the logging.

7ce658d14c autotest: pre-assign all UIDs of the test messages
this ensures stable results when the boxes are used with different
OPEN_FLAGS (which will happen in a subsequent commit), at the negligible
cost of removing the implicit test of the maildir driver's ability to
enumerate new messages.

4cc5ad5a1a introduce driver call debugging
do that by wrapping the actual stores into proxies.

the proxy driver's code is auto-generated from function templates, some
parameters, and the declarations of the driver functions themselves.
attempts to do it with CPP macros turned out to be a nightmare.
