OfflineIMAP v6.5.1 (2012-01-07) - "Quest for stability"
=======================================================
* Fixed Maildir regression "flagmatchre" not found. (regressed in 6.5.0)
* Have console output go by default to STDOUT and not STDERR (regression
in 6.5.0)
* Fixed MachineUI to urlencode() output lines again, rather than
outputting multi-line items. It's ugly as hell, but it had been that
way for years.
* Remove the old global locking system. We lock only the accounts that
we currently sync, so you can invoke OfflineImap multiple times now as
long as you sync different accounts. This system is compatible with
all releases >= 6.4.0, so don't run older releases simultanous to this
one.
THe new logging framwork spit putput to STDERR by default (as that is
pythons default), but we used to have STDERR, so make it go there again.

Previously, assigning a new UID to a mapped IMAP or Maildir repository
was done by loading the "local" item, saving it under a new UID and
deleting the old one. This involved lots of disk activity for nothing
more than an effective file rename in Maildirs, and lots of network
usage in the MappedUID cases.
We do this on every upload from a local to a remote item, so that can
potentially be quite expensive. This patch lets backends that support it
(Maildir, MappedUID) efficiently rename the file rather than having to
read the mail content, write it out as a new file and delete the old
file. This speeds up uploads from Maildir and the MappedUID server.

When a new remote folder was detected, we tried to create the folder
locally on the Maildir and called repository.forgetfolders() to force a
new scanning of the Maildir. However, that implementation used the
inherited base function that did nothing. We simply needed to implement
forgetfolders() to set self.folder=None, so we would force a new read in
of the updated local folder structure.

Previously, we would simply bail out in an ugly way, potentially leaving
temporary files around etc, or while writing status files. Hand SIGINT
and SIGTERM as an event to the Account class, and make that bail out
cleanly at predefined points. Stopping on ctrl-c can take a few seconds
(it will e.g. finish to transfer the ongoing message), but it will shut
down cleanly.

We need the list of folders and the folder delimiter, but it was not
always retrieved early enough. E.g. when doing IMAP<->IMAP sync and the
local IMAP being readonly, we would bunk out with a mysterious error
message become repository.getsel() would still return None.
This commit fixes this error.

The default parameter value was "None", and we were comparing that
directly to the imaplib2 value of is_readonly which is False or True, so
the comparison always returned "False".
Fix this by setting the default parameter to "False" and not
"None". Also convert all users of that function to use False/True.

Drop a connection, if the NOOP to keep a connection open fails due to
broken connections.
Note that I believe this function is not working as intended. We grab
one random connection and send a NOOP. This is not enough to keep all
connections open, and if we invoke this function multiple times, we
might well always get the same connection to send a NOOP through.

If we create a new folder we would previously not update our folder
list, which led to us skipping the synchronization of those new folders
during the initial run (subsequent runs would pick it up).
Invalidate the folder cache when we create a folder during folder
structure sync. Regetting the whole list from an IMAP server might be
slightly suboptimal from a performance point, but it is easy and will
lead to consistent results. Hopefully we will not have to create new
folders on each new run.

Modify the UI:acct and acctdone functions to keep tab of the time
inbetween. Put self.ui.acct() and acctdone() at the right places in
accounts.py so that the timing happens at the right places.
While modifying that loop, flatten the nested try: try: except: finally:
constructs, we require python 2.5 now which copes with that.
At the end of each account sync you will now see something like:
*** Finished account 'test' in 0:05

Registering a thread (associating it with a certain account name) would
fail if it was already registered. However, as we a) never unregister most
threads (bad) and b) single-threaded mode reuses threads, we failed when
syncing multiple accounts in single-threading mode.
This commit cleans up the functions to not make re-registering a thread
fatal (it could be legitimate, however it *should* not occur). Future
work needs to be done to unregister new threads at the appropriate places.

Some Webservers (I am looking at you Gmail) send different capabilities
before and after login, so they can tailor their server capabilities to
the user. While legal, this is uncommon and we were not updating our
server capabilities. Doing so allows us to detect that Gmail actually
supports the UIDPLUS extension, and we will stop mangling headers when
uploading to Gmail. This could lead to some performance gains when we
upload many messages to Gmail.

Previously, we were simply locking offlineimap whenever it was
running. Howver there is no reason why we shouldn't be able to invoke it
in parallel, e.g. to synchronize several accounts in one offlineimap
each.
This patch implements the locking per-account, so that it is possible to
sync different accounts at the same time. If in refresh mode, we will
attempt to loop three times before giving up.

open() and os.open() lead to different file permissions by default, and

If we connect to a SSL server (not STARTTLS) and no CA cert has been
specified for verification, we check the configured SSL fingerprint and
bail out in case it has not been set yet, or it does not match.
This means one more mandatory option for SSL configuration, but it
improves security a lot.

imaplib renamed self.sslobj to self.sock and our overriden open()
functions were failing for that reason when updating imaplib2 to
v2.28. It turns out that all of our custom initializations are being
done by stock imaplib2 now anyway, so there is no need to override them
anymore. This lets us simplify the code we have to worry about.
Move the verifycert() function to the imapserver.py file, it is now a
callback function that is being handed to imaplib from there, so it
makes sense to also define it in our imapserver function...
(this also lets us easily make use of the verifycert function in the
starttls case in the future)

select() function, it is the only reason why we still wrap the IMAP4

Remove a level of wrapper abstraction that is not needed. Just use
IMAPserver and be done with it.
We do this by passing in the IMAPRepository() instance rather than a
long list of single paramters to the IMAPServer instanciation. This way
we can retrieve all repository parameters ourselves, rather than passing
a dozen paramters into IMAPServer. Also, this enables us to pass the
repository() object into our WrappedIMAP4() instance, so that it can
query, e.g. the SSL fingerprint configuration.
