343f16771a don't crash when select() on master fails synchronously 
svars->drv[S] would not be initialized yet, so cancel_sync() would
crash.

28cccf4b35 fix error handling of invalid SyncState * 
when we find that the store is incompatible with in-store sync state,
we want to fail the whole channel. however, we must not claim that the
store died, otherwise it won't be disposed of properly.

9c86ec3442 employ alternative scheme to finding messages by TUID 
instead of SEARCHing every single message (which is slow and happens to
be unreliabe with M$ Exchange 2010), just FETCH the new messages from
the mailbox - the ones we just appended will be amongst them.

7c815538ab fix line wrapping before info messages 
unless an info message is explictly marked as a continuation, it must
terminate any pending line (typically the progress information) first.

debug output is not affected, as it is mutually exclusive with info
output, and no debug lines are left unterminated outside clear scopes.

d2bed4990d unify error reporting 
- introduce sys_error() and use it instead of perror() and
  error(strerror()) in all expected error conditions
- perror() is used only for "something's really wrong with the system"
  kind of errors
- file names, etc. are quoted if they are not validated yet, so e.g. an
  empty string becomes immediately obvious
- improve and unify language
- add missing newlines

424e0e7221 make callbacks return early when canceling 
even after driver->cancel() the store may complete commands successfully.
return early in this case, so we don't attempt to continue syncing.

ea951a697f fix error paths wrt sync drivers, take 2 
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.

 2012-07-30 01:21:32 +02:00

b0bbd23512 replace DRV_STORE_BAD with a separate bad_callback() 
that way we don't have to piggy-back (possibly asynchronous) fatal
errors to particular commands.

internally, the drivers still use synchronous return values as well,
so they don't try to access the invalidated store after calling back.

6d86e5347e don't access free'd memory in cancel_sync() 
as it happens, the 1st round *may* trash svars - if we get the
cancelation request after the slave store has already died.

9554026443 make drv->cancel()'s callback have no status code 
this function is not going to actually execute any commands, so it
makes no sense for the callback to have a status code.

57444e9df9 don't decode aux pointer on DRV_CANCELED

get this status code.

296ac0364c add CR after TUID during LF => CRLF conversion 2011-03-27 11:54:02 +02:00
Oswald Buddenhagen
8df1ebaf40 fix (another) out-of-bounds access in CRLF conversion 
if the header contained no CRs but the body (or the post-TUID part of
the header) did, the TUID insertion would add an excess CR, thus
overflowing the buffer by one byte.

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).

bc39f10a1e lock the sync state open the journal before opening the master. this is 
a bit ugly for the "SyncState *" case, as we have to create a directory
without making it a maildir right away. however, this makes the code
quite a bit simpler to understand and simpler to parallelize.

8c30ec4a25 put message references into the sync records. match up the uids after

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.

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.
