b4cef554fc clearer debug msg 2012-09-01 21:15:07 +02:00
Oswald Buddenhagen
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

584e51ed7d docs
- insert "separator comments" between driver entry points
- document driver API
- document sync_vars_t parts that are stored in the sync state header

e5d323cc47 rely on the maildir's existence with "SyncState *"
now that we open the box first, we know that it will exist at this
point.

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.

ec8f440383 don't call cancel() repeatedly on a store
erroring command replies will trickle in even after canceling

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
the aux data was already free()d by the error callback by the time we
get this status code.

058d01f179 don't compare find_old_done with find_new_total

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.
