1e427f5cd5 do not unnecessarily use bitfields 
they don't save much (if any) space in our usage, while they make the
machine code more bloated and slow.

49a32910a7 move handling of new messages after that of old ones 
i.e., move it back. whatever the original reason was, it's now gone.

this order is way more natural, which allows us to remove the osrecadd
and S_DONE hacks.

b1842617f7 make MaxMessages work for new mails as well 
this helps enormously on the first sync of a 100k message box with a
limit of 1k messages. it also happens to make the syncing idempotent.

in a few conditionals we now explicitly test for max_messages being
enabled, not smaxxuid != 0, as after the initial fetch with no important
messages smaxxuid is zero, but we still have to skip over 99k messages
in the above case.

d3f6347021 delay propagation of new messages 
previous sequence:
  examine & propagate new => examine old => propagate old
new sequence:
  examine new => examine old => propagate new => propagate old

this alone does not buy us much ...

7f784fd235 log maxuid bumping less aggressively 
we can bump the internal variable whereever convenient, but we cannot
log it until we know that all messages were copied, as otherwise we
could miss some new messages after an interruption. with the new
approach, interruption would merely cause some additonal traffic.

Oswald Buddenhagen
ecb4c7ab07 propagate deletions with other flag changes 
less code duplication, more logical order of issued driver commands
(especially after the next commit), and the "side effect" of letting the
message expiration code see those deletions if they are asynchronous.

273ac899f3 don't delay loading master even if messages were expired 
the delay optimized the corner case of previously important but now
expired messages on the slave disappearing, either through an external
expunge or after a journal replay. no point in pessimizing the common
case.

12676f28da remove cleanup of expired entries during setup of master load 
the removed code would only ever trigger if a) we were after a journal
replay or b) something external expunged the expired messages - both are
corner cases not worth the extra code.
however, this means that the syncing code further down now needs to take
care of these zombies.
in the end, the normal cleanup will take care of all expired entries,
new and old.

Oswald Buddenhagen
83b834cdfd count unread messages like flagged messages when expiring 
that is, don't count them towards the total only below the cut-off
point. making them extend the working set even though they are inside it
is counterintuitive.

9e186ae88b use post-sync "seen" flag to determine expirability

15216947fb don't protect recent messages from MaxMessages 
while maildir has a clearly defined meaning of "recent" and for example
mutt handles it graciously, IMAP's definition is fubared to the point
that some servers (for example gmail) simply refuse to support it.
for symmetry reasons it is best to pretend that it doesn't exist at all.
it doesn't seem too useful anyway (the user can simply mark the messages
as read to allow pruning).
and last but not least, the man page of mbsync says nothing about
"recent", only "unread". unlike the isync man page, though.

6b7b2b1106 always get slave flags when we are expiring 
even if we are not propagating new messages, the appearance of new
messages on the slave can lead to expiring older messages. for that, we
need to know their importance, and thus flags.

the alternative would be not doing an expiration run when not fetching
new messages, but that would mean more conditionals all over the place.
as the decision is somewhat arbitrary, just do the simpler thing.

a893cba483 fix enum abuse 
amends 9c86ec344.

S_FIND was for the sync record status field. it has no business in the
sync vars status fields. its value coincided with ST_SELECTED, which
luckily only means that we always tried to match up TUIDs even if there
was nothing to do.

the need for TUID matching arises in two mostly independent
circumstances, so add two separate flags ST_FIND_{OLD,NEW}.

9261897629 don't record newuid in the sync state 
this value is only ever used to find just pushed messages by TUID, so we

the new value after completing a search, as there won't be a next search
before we push the next messages.

this is no problem if the certificate file contains only exactly the
wanted host's certificate - before revision 04fdf7d1 (dec 2000, < v0.4),
this was even enforced (more or less - if the peer cert had been
signed directly by a root cert, it would be accepted as well).
however, when the file contains root certificates (like the system-wide
certificate file typically does), any host with a valid certificate
could pretend to be the wanted host.

  have to be re-fetched "behind mbsync's back" (just deleting the files
  would not work - see above)

in fact, UIDNEXT (and UIDVALIDITY) null is *not* allowed (see RFC3501

having it in as a workaround was no good either, as quite some other
code in mbsync assumes that UIDs are not null.

    - last sent command requires round-trip
    - command has a dependency on completion of previous command
  - trashnc is tri-state so only a single "scout" trash APPEND/COPY is
    sent at first. a possibly resulting CREATE is injected in front of
    the remaining trash commands, so they can succeed (or be cancel()d
    if it fails).

synchronous error codes which are passed through callbacks aren't a
particularly good idea, after all: latest when the callback does stuff
which does not concern the caller, the return code becomes ambiguous.
instead, protect the sync_vars object with a refcount when invoking
driver functions from loops, as the callbacks they call could invalidate
the object and we would have no way of knowing that the loop should be
aborted prematurely. the upcoming async imap driver will also need a
refcount to protect the cancelation marker of the imap socket dispatcher
loop.

d94dadbaeb fix line ending conversion logic 
imap may very well store messages with LF line endings. only RFC2822
requires CRLF.
consequently, preserve the line endings as much as possible unless the
mailbox format does not support it (this would be the case for unix mbox
- i actually have no idea about maildir).

4dc23fee7b why would somebody manipulate an expired message? right, he wouldn't: 
he would either expunge the mailbox or configure his MUA to hide trashed
messages. consequently don't sync expired message flags, let alone
interpret them in a special way.
one special feature remains, though: if a non-expunged expired message
is flagged on the master, it will be unexpired on the slave. i'm not
sure whether i should remove or document this feature.

socket_write should be (re)moved, but as long as the .cont callback is
used only for this ...

16de402c9e when storing \seen messages, don't set the \recent flag on them. could 
well be that this is incorrect, but some mailers need it that way.
when trashing messages, preserve their \recent status as well.

130664b622 The Big Rewrite. too many change to list them all. 
as opposed to earlier threats, BerkDB was not entirely dropped; i
suppose the isync 0.7 -> 0.8 change had a reason, so i added an
alternative UID storage scheme.
note that BDB 4.0 is not sufficient, as the db->open function changed in
an incompatible way ...

i updated the debian packaging except for a changelog entry.
note that i removed the upgrade blurb, as upstream now has a smooth
upgrade path down to at least isync 0.4.
