2a852a8f48 Rework keepalive to use time.sleep() instead of event.wait()
This should improve power-management abilities some more

The catch is that we can't wait any longer for the kathread to
terminate.  We were waiting for this in some cases.  This is probably
not a big deal.

f549baa074 UNDO: Synchronize newly created folders both ways
This involves several changes at different places:

- syncfoldersto() takes statusfolder as an argument, and returns the
  list of new folders and the list of folders that should be ingnored,
  typically those that were deleted. Warns the user about folders that
  are present only on one side and are not synced.

- syncfoldersto() is called both ways, and on folder creation
  forgetfolders() is used to rebuild the list and take the new creation
  into account. Probably not the most efficient, since it involves
  talking to the IMAP server again, but it will rarely be used anyway.

- Locally created folders are treated separately in the synchronization,
  namely the local messages are uploaded and then the normal sync still
  occurs. If the same folder is created on both sides and contains
  messages on both sides, a two-way sync occurs.

3305d8cd4d Daniel Jacobowitz patches
fixes deb#433732

Date: Sun, 30 Sep 2007 13:54:56 -0400
From: Daniel Jacobowitz <drow@false.org>
To: offlineimap@complete.org
Subject: Assorted patches

Here's the result of a lazy Sunday hacking on offlineimap.  Sorry for
not breaking this into multiple patches.  They're mostly logically
independent so just ask if that would make a difference.
First, a new -q (quick) option.  The quick option means to only update
folders that seem to have had significant changes.  For Maildir, any
change to any message UID or flags is significant, because checking
the flags doesn't add a significant cost.  For IMAP, only a change to
the total number of messages or a change in the UID of the most recent
message is significant.  This should catch everything except for
flags changes.

The difference in bandwidth is astonishing: a quick sync takes 80K
instead of 5.3MB, and 28 seconds instead of 90.

There's a configuration variable that lets you say every tenth sync
should update flags, but let all the intervening ones be lighter.


Second, a fix to the UID validity problems many people have been
reporting with Courier.  As discussed in Debian bug #433732, I changed
the UID validity check to use SELECT unless the server complains that
the folder is read-only.  This avoids the Courier bug (see the Debian
log for more details).  This won't fix existing validity errors, you
need to remove the local status and validity files by hand and resync.


Third, some speedups in Maildir checking.  It's still pretty slow
due to a combination of poor performance in os.listdir (never reads
more than 4K of directory entries at a time) and some semaphore that
leads to lots of futex wake operations, but at least this saves
20% or so of the CPU time running offlineimap on a single folder:

Time with quick refresh and md5 in loop: 4.75s user 0.46s system 12%
cpu 41.751 total
Time with quick refresh and md5 out of loop: 4.38s user 0.50s system
14% cpu 34.799 total
Time using string compare to check folder: 4.11s user 0.47s system 13%
cpu 34.788 total


And fourth, some display fixes for Curses.Blinkenlights.  I made
warnings more visible, made the new quick sync message cyan, and
made all not explicitly colored messages grey.  That last one was
really bugging me.  Any time OfflineIMAP printed a warning in
this UI, it had even odds of coming out black on black!


Anyway, I hope these are useful.  I'm happy to revise them if you see
a problem.

Attached is a new diff that should work though not really tested
(v4.0.14). In repository/Base.py restore_atime() will call
self.restore_folder_atimes() only if the folder type is Maildir. Let me
know if it has any more problems.

405275f541 New restoreatime patch
From: Ben Kibbey <bjk@luxsci.net>

Attached is a patch to restore the atime of Maildir folders after
syncing. It can be enabled via the 'restoreatime' boolean in the
configuration file. I needed this because offlineimap is run after a
fetchmail and my mail checker breaks.
