Most servers support the UIDPLUS extension, and we don't have to search
headers after each uploaded message. There is no need to CHECK the imap
server after each message when there is no need to search headers.
I have not measured the performance impact on real world servers, but
this lets us do less unneeded work in the common case.

We were not cleaning out possibly existing APPENDUID messages before
APPENDing a new message. In case an old message were still hanging
around, this could *possibly* lead to retrieving and old UID. Things
should have been fine, but we do want to play safe here.
Also, make use of the "official" imaplib2 .response() command rather
than the internal _get_untagged_response() function.
Remove the hack that we would be looking for APPENDUID responses even if
the server claimed not to support the UIDPLUS ext. We now poll server
CAPABILITIES after login, and Gmail does provide us with the UIDPLUS
capability after login.

imaputil.imapsplit did not cope with strings that contained encoded

Rename getuidvalidity -> get_uidvalidity and cache the IMAP result.
1) Start modernizing our function names using more underscores
2) IMAPs implementation of get_uidvalidity was removing the UIDVALIDITY result
from the imaplib2 result stack, so subsequent calls would return "None".
As various functions can invoke this, this led to some errors that we
avoid by caching the current UIDVALIDITY value in the Folder instance.
There are more simplifications and improvements to be made.

We were using super() on a class derived from logging.Formatter() which
worked fine in python 2.7. Apparently python 2.6 uses old-style classes
for this, so the TTYUI broke and crashed OfflineImap. This was
introduced in OLI 6.5.0, I think.
Fix it by calling logging.Formatter.... directly, rather than the
elegant super() (which I happen to like a lot more than is appropriate
in the python world).
Reported by Nik Reiman as github issue 23, should fix that issue.

When deleting many (eg 2000) mails using the SQLITE backend, this takes
a long time durig which OfflineImap can not be aborted via
CTRL-C. Thinking it had frozen permanently, I killed it hard, leaving a
corrupted db journal (which leads to awkwards complaints by OLI on
subsequent starts!). That shows that delete performance is critical and
needs improvement.
We were iterating through the list of messages to delete and deleted
them one-by-one execute()'ing a new SQL Query for each message. This
patch improves the situation by allowing us to use executemany(), which
is -despite still being one SQL query per message- much faster. This is
because rather than performing a commit() after each mail, we now do
only one commit() after all mails have been deleted.

Recently the internal function use of imaplib2's _get_untagged_response()
was switched to use the public documented .response() function (which
should return the same data). However within a few fays we received reports
that both uses of a) the UIDVALIDITY fetching and b) the APPENDUID fetching
returned [None] as data although the IMAP log definitely shows that data
was returned. Revert to using the undocumented internal imaplib2 function,
that seemed to have worked without problems. This needs to be taken up to

Subject: [PATCH] Only scan children in _getfolders_scandir if extension is set.
When sep is '/', MaildirRepository._getfolders_scandir recursively
checks sub-directories for additional maildirs. The old loop logic
always checked the top directory and its children. This lead to
children being found twice, once from their parent, with dirname
matching their directory name, and once from themselves, with a
dirname of ''.
This patch fixes the problem by only checking the top directory when
extension is not set (i.e. for the root directory).
Do not read in custom maildir flags, or we would try to sync them over
the wire. The next step will be to merge flag writes with existing
custom flags, so we don't lose information.
The long term goal will be to attempt to sync flags to the other side,
of course.

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.

This change looks harmless, but it fixes a severe bugfix, potentially
leading to data loss! It fixes the "on n new uploads, it will redownload
n-1, n-2, n-3,... messages during the next syncs" condition, and this is
what happens:
If there are more than one Mails to upload to a server, we do that by
repeatedly invoking folder.IMAP.savemessage(). If the server supports
the UIDPLUS extension we query the resulting UID by doing a:
imapobj._get_untagged_response('APPENDUID', True)
and that is exactly the problem. The "True" part causes the reply to
remain in the "response stack" of the imaplib2 library. When we do
the same call on a subsequent message and the connection is still on the
same folder, we will get the same UID response back (imaplib2 only looks
for the first matching response and returns that). The only time we
clear the response stack, is when the IMAP connection SELECTS a
different folder.
This means that when we upload 10 messages, the IMAP server gives us
always the same UID (that of the first one) back. And trying to write
out 10 different messages with the same UID will confuse OfflineIMAP.
This is the reason why we saw the ongoing UPLOADING/DOWNLOADING behavior
that people reported. And this is the reason why we saw the
inconsistency in the UID mapping in the IMAP<->IMAP case.
I urge everyone to upgrade ASAP. Sorry for that, I don't know why the
problem only became prevalent in the recent few releases as this code
has been there for quite a while.

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.

If someone had a custom :2,a flag, adding a new flag would lead to the
invalid maildir filename ...a:2,... due to regex deficiencies not coping
with this. Fix this so we alway produce valid maildir names.
Note that custom flags are still problematic: as the syncing to the
remote IMAP server will fail, the next sync will assume that they have
been removed from the remote IMAP side and they will be removed from the
local Maildir then. We will need to think about how to handle this. At
least, with this patch we won't lose standard flags and won't produce
invalid maildir names.
Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de>
The regex for catching Maildir message flags was

When a new remote folder was detected, we tried to create the folder
locally on the Maildir and called repository.forgetfolders() to force a

1) Rename the unintuitive repository.syncfoldersto() to

2) We were checking if the local repository is readonly and then turning

a folder on the repository that is marked readonly=True.
