1ebc45d963 Fix performance for SSL
Added WrappedIMAP4_SSL class to help fix up performance of SSL

Standard imaplib.py is really bad with this, since it reads one
character at a time.

  I just noticed that the version of offlineimap I've been using
  (3.99.17) is well over four years old.  How time flies.  I haven't
  had any problems with it, but out of curiosity I decided to pull in
  5.99.2 from the fedora repository.  It turns out to take
  consistently over twice as long as the old version to sync the same
  account.  Is this expected?

  The following changeset is the one responsible for the difference in
  speed I was noticing between the imaplib.py that was packaged with
  older versions of offlineimap and the one that comes with python:

08a579657a Fix handling of servers that return UIDs in some FETCH responses
closes #22

from pistore in OfflineIMAP #22:

When an IMAP flag update is performed for multiple messages, some IMAP
servers (e.g. Exchange) return the UID attribute only for some of the
FETCH untagged responses, as shown in the following log:

21:19.04 > DCKF8 UID STORE 66050,50613,52164,40043,40055,25874 +FLAGS
(\Deleted)
21:19.36 < * 35 FETCH (FLAGS (\Seen \Deleted) UID 25874)
21:19.36 < * 321 FETCH (FLAGS (\Seen \Deleted))
21:19.57 < * 322 FETCH (FLAGS (\Seen \Deleted))
21:19.57 < * 560 FETCH (FLAGS (\Seen \Deleted))
21:19.57 < * 581 FETCH (FLAGS (\Seen \Deleted) UID 52164)
21:19.62 < * 1022 FETCH (FLAGS (\Seen \Deleted))
21:19.62 < DCKF8 OK STORE completed.

Function IMAPFolder.processmessagesflags is able to manage the servers
which return the UID and the servers which do not return it, but is
not able to deal with the mixed behavior shown above.

The problem is that the fragment of function
IMAPFolder.processmessagesflags that handles the responses with UID
attribute uses variable flags to store the list of flags of the
message in the IMAP format ("flags = attributehashFLAGS?"), while the
fragment that handles the responses without UID expects variable
"flags" to contain the list of modified flags passed to the function
in Maildir format ("self.messagelist[uid]flags?.append(flag)").

As a consequence, the wrong list of flags is used for the messages
without UID, leading to the addition of "strange" flags to the Maildir
messages:

Syncing messages IMAP[INBOX] -> Maildir[.]
Adding flags   to 4 messages  on Maildir[.]
Adding flags e to 4 messages  on Maildir[.]
Adding flags d to 4 messages  on Maildir[.]
Adding flags ) to 4 messages  on Maildir[.]
Adding flags ( to 4 messages  on Maildir[.]
Adding flags l to 4 messages  on Maildir[.]
Adding flags n to 4 messages  on Maildir[.]
Adding flags t to 4 messages  on Maildir[.]
Adding flags \ to 4 messages  on Maildir[.]
Adding flags D to 4 messages  on Maildir[.]
Deleting flags T to 4 messages on Maildir[.]
Adding flags   to 4 messages  on LocalStatus[.]
Adding flags e to 4 messages  on LocalStatus[.]
Adding flags d to 4 messages  on LocalStatus[.]
Adding flags ) to 4 messages  on LocalStatus[.]
Adding flags ( to 4 messages  on LocalStatus[.]
Adding flags l to 4 messages  on LocalStatus[.]
Adding flags n to 4 messages  on LocalStatus[.]
Adding flags t to 4 messages  on LocalStatus[.]
Adding flags \ to 4 messages  on LocalStatus[.]
Adding flags D to 4 messages  on LocalStatus[.]
Deleting flags T to 4 messages on LocalStatus[.]

Fix: use a different variable to store IMAP flags when managing
messages corresponding to responses with UID attribute, e.g.:

*** IMAP.py.orig        Wed Aug 22 18:23:17 2007
--- IMAP.py     Wed Aug 22 18:22:38 2007

Unfortunately I have to fetch some of my mail from an Exchange server
(Microsoft Exchange Server 2003 IMAP4rev1 server version 6.5.7638.1)
and I can confirm that the analysis of the problem is correct, and the
patch given here fixes the problem.

Looking at the code of the processmessagesflags() method I think it
generally is a bug that the "flags" parameter is reused as a local
variable, since the final "for uid in needupdate:" loop needs the
original value of "flags". This only worked by accident.

I'm attaching a unidiff version of the patch which applies cleanly
against Debian unstable's offlineimap 5.99.4.

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.

6caaea36e0 Fix Maildir race
fixes deb#439384

From: martin f krafft
Subject: race condition in Maildir writing

The offlineimap Maildir code checks for file existence and then
opens a file. That's open to a race condition. It's better to open
the file and fail if it already exists. The following patch does
this. It catches OSError 17 (file exists) and re-raises all others.
I'll leave it up to you to decide whether this is appropriate.

From: "Mark A. Hershberger"

https://bugs.launchpad.net/ubuntu/+source/offlineimap/+bug/96710

the locked() method isn't implemented for non-interactive UIs, so
exceptions are thrown on cron jobs.  Ubuntu's new apport catches these
and ? well, you get the idea.

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.

2323fdcdb3 Additional date validity check
patch from Mike Gerber

Two times today I have found my offlineimap to have died with this same
situation. It appears as if certain types of messages (both spam in my
situation), cause offlineimap to choke. When it does it cannot proceed.
This means that when I run offlineimap, it pulls in messages from some
folders, then it hits the folder with the bad message and dies, leaving
undownloaded mail on the server. The only fix to this problem is to find
the problem message on the server and remove it by hand. This isn't such
a huge deal for me, since I run the server, but other people have to
come to me to ask me to delete these messages, and until I do they
cannot download their email.

I have captured the output by running script during one of these
incidents, this has been attached. Additionally, I have also attach the 
problematic message.

The patch seems to work for me, might need some Python wizard and better 
testing, though.
