this also adds code which avoids that the message about excluding the
mailbox is printed multiple times - this could happen with Maildir++, as
the hierarchy is flattened.
amends 0f24ca31b.
we need a separate log entry type which does proper mmaxxuid tracking.
while moving code around, this also removes a redundant debug statement.
amends b1842617.
newmaxuid represents the highest UID for which a sync entry was created,
while maxuid represents the end of the range which is guaranteed to have
been propagated. that means that the former needs to be instantly
incremented (and logged), while the latter must not be touched until the
entire new message sync completes. this matters particularly in the case
of resuming an interrupted run, where sync entry creation must resume
exactly where it left off, while loading the box must use the old limit
to ensure that all messages are available for actual propagation.
we've been using indices to separate master/slave state for a long time,
so there is no point in using pairs of matching brackets to signify the
side in the journal. instead, use somewhat descriptive letters (S[een],
F[ind], T[rashed]) and the index itself.
they are derived from srec->status, which is unsigned. for not
understood reasons, the compiler complains only after extending status
to a full unsigned int.
on the way, localize the declarations.
latest since 77acc268, the code prior to these statements ensures that
the full length is available, so just use memcpy(). the code for
comparing TUIDs uses memcmp() anyway.
introduce recognition of $USE_VALGRIND to run all mbsync invocations
through valgrind.
this also removes the seemingly purposeless --log-fd=3 indirection.
when syncing flags but not re-newing non-fetched messages, there is no
need to query the message size for all messages, as the old ones are
queried only for their flags.
instead of a single hard-coded branch, use a generic method to split
ranges as needed.
this is of course entirely over-engineered as of now, but subsequent
commits will make good use of it.
turns out the comment advising against it was bogus - unlike for
memcmp(), the standard does indeed prescribe that the memchr()
implementation may not read past the first occurrence of the searched
char.
that's what the sources already assumed anyway. size_t is total
overkill, as No Email Ever (TM) will exceed 2GiB.
this also fixes a harmless format string warning in 32 bit builds.
