While improving the test suite, I noticed that we would not create folders on
the remote in some cases when we should (yay for test suites!). This is because
we were testing the untransposed LOCAL foldername and check if it existed on
the remote side when deciding whether we should potentially create a new folder.
Simplify the code by transposing the LOCAL folder names in dst_hash, saving us
to create another confusing "newsrc" temp variable. Make the code a bit more
readable by using dst_name_t to indicate we operate a transposed folder name.
This now passes test 03 (using invalid nametrans rules) when test 03 would pass
before.

Rename variable src_name to src_name_t to indicate that it is the transposed
name. Also rather than testing the hash thingie, we can simply test for
"if source_name_t in dst_folders" now.

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

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).

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.

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.

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

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.
