d47bd1ff89 Change keepalive() to spawn IdleThreads
This is the commit that enables IDLE support. In order to do this, we
hijack the keepalive method. Instead of just sending NOOPs, it now
sends IDLE and responds accordingly, thanks to the IdleThread class.

9fa6bcdf82 Add IdleThread class
This encapsulates the logic for sending a keepalive/IDLE call,
including starting a sync if needed.

This code was originally by James Bunton <jamesbunton@fastmail.fm>.  I
modified the idle() method to put the select() call after
acquireconnection().

694e5772da threadutil: remove broken os.exit()
We are missing the import of 'os' python module since commit d839be3c61
(Sat Apr 16 20:33:35 2005 +0100) which was when John switched from SVN to Git.

Happily, it help us today: we still had no feedback for this missing import,
6 years later.  So, we can remove the os.exit() call safely.

That beeing said, we still don't know if the above sys.exit() was ever touched.
My guess is that it never was. Keep this (hopefully) commented statement to
ensure the thread terminate and not play too much with the Murphy's law. :-)

c70a621709 Limit msg body length in debug output
We were outputting full message bodies to the debug log (often stderr),
and then again (as they go over the imaplib2 wire, imaplib logs
everything too). Not only is quite a privacy issue when sending in debug
logs but it can also freeze a console for quite some time. Plus it
bloats debug logs A LOT.

Only output the first and last 100 bytes of each message body to the
debug log (we still get the full body from imaplib2 logging). This
limits privacy issues when handing the log to someone else, but usually
still contains all the interesting bits that we want to see in a log.

89619838b0 Remove weird SigListener class
The SigListener class was used to queue folders that we need to sync and
to receive "resync" and "abort" signals. It was undocumented and weird
and we had to pass "siglisteners" through the whole program.

Simply do away with it, and make 2 functions in the Account() class:
set_abort_event and get_abort_event which can be used to set and check
for such signals. This way we do not need to pass siglisteners all over
the place. Tested Blinkenlights and TTYUI uis to make sure that SIGUSR1
and SIGUSR2 actually still work.

Document those signals in MANUAL.rst. They were completly undocumented.

This simplifies the code and interdependencies by passing less stuff
around. Removes an undocumented and weirdly named class.

versions since at least 2008 are.
But, as it still causes errors when 2

writes with a per class, ie per-connection lock. Factor out the retrying
to write when the database is locked.

e1e9c8e831 Use self.doautosave rather than self.dofsync
doautosave was a useless variable before (it was *always* 1). So we
remove the self.dofsync variable and store in doautosave whether we
should fsync as often as possible (which really hurts performance).

The sqlite backend could (at one point) use the doautosave variable to
determine if it should autocommit after each modification.

- Don't fail if pysql import fails. Fail rather at runtime when needed.

- When creating the db file, create a metadata table which contains the
  format version info, so we can upgrade nicely to other formats.

- Create an upgrade_db() function which allows us to upgrade from any
  previous file format to the current one (including plain text)

Using threading._VERBOSE=1 is broken since python 2.6 till at least
python 3.2, (http://bugs.python.org/issue4188) so we can't use it for
our thread debugging.

Remove the usage of threading._VERBOSE, and implement a "light thread
debug log" that for now outputs information when a new thread is being
registered and when it is being unregistered. I am sure we will be able
to add more thread debugging information over the time.

Besides '-d thread' this will re-enable the usage of -d 'all' for the
most verbose debugging of all categories.

e20d8b9679 Remove upload neguid pass from sync logic
In order to optimize performance, we fold the 1st and 2nd pass of our
sync strategy into one. They were essentially doing the same thing:
uploading a message to the other side. The only difference was that in
one case we have a negative UID locally, and in the other case, we have
a positive one already.

This saves some time, as we don't have to run through that function on
IMAP servers anyway (they always have positive UIDs), and 2nd were we
stalling further copying until phase 1 was finished. So uploading a
single new message would prevent us from starting to copy existing
regular messages.

36eb37b47d IMAP: reduce quickchanged() checks
For each folder we were making a second IMAP request asking for the
latest UID and compared that with the highest UID in our
statusfolder. This catched the case that 1 mail has been deleted by
someone else and another one has arrived since we checked, so that the
total number of mails appears to not have changed.

We don't capture anymore this case in the quickchanged() case.

It improves my performance from 8 to about 7.5 seconds per check (with lots of
variation) and we would benefit even more in the IMAP<->IMAP case as we do one
additional IMAP lookup per folder on each side then.

Do cleanups on whitespaces while in this file.

ca012d3a81 Implement more efficient functions for the MappedUID case
We are calling getmessagelist() internally a lot, e.g. just to check if
a UID exists (from uidexist()). This is a very expensive operation in
the UIDMapped case, as we reconstruct the whole messagelist dict every
single time, involving lots of copying etc.

So we provide more efficient implementations for the uidexists()
getmessageuidlist() and getmessagecount() functions that are fast in the
UIDMapped case. This should solve the performance regression that was
recently observed in the Mapped UID case.

09515f8f90 Increase compatability with Gmail
When uploading a new message to Gmail we need to find out the UID it
assigned it, but Gmail does not advertize the UIDPLUS extension (in all
cases) and it fails to find the email that we just uploaded when
searching for it. This prevented us effectively from uploading to
gmail.

See analysis in
http://lists.alioth.debian.org/pipermail/offlineimap-project/2011-March/001449.html
for details on what is going wrong.

This patch increases compatability with Gmail by checking for APPENDUID
responses to an APPEND action even if the server did not claim to
support it. This restores the capability to upload messages to the
*broken* Gmail IMAP implementation.

1bf4bee5e6 Update to match semantics of new imaplib2
The biggest change here is that imapobj.untagged_responses is no
longer a dictionary, but a list. To access it, I use the semi-private
_get_untagged_response method.

* offlineimap/folder/IMAP.py (IMAPFolder.quickchanged,
  IMAPFolder.cachemessagelist): imaplib2 now explicitly removes its
  EXISTS response on select(), so instead we use the return values from
  select() to get the number of messages.

* offlineimap/imapserver.py (UsefulIMAPMixIn.select): imaplib2 now
  stores untagged_responses for different mailboxes, which confuses us
  because it seems like our mailboxes are "still" in read-only mode when
  we just re-opened them.  Additionally, we have to return the value
  from imaplib2's select() so that the above thing works.

* offlineimap/imapserver.py (UsefulIMAPMixIn._mesg): imaplib2 now
  calls _mesg with the name of a thread, so we display this
  information in debug output. This requires a corresponding change to
  imaplibutil.new_mesg.

* offlineimap/imaplibutil.py: We override IMAP4_SSL.open, whose
  default arguments have changed, so update the default arguments. We
  also subclass imaplib.IMAP4 in a few different places, which now
  relies on having a read_fd file descriptor to poll on.

0a76f0a23d Import newest version of imaplib2
This change does not do anything yet with imaplib2, merely makes it
available for future commits.

This file is identical to the one at
http://sydney.edu.au/engineering/it/~piers/python/imaplib2 .

imaplib2, written by the same guy who wrote imaplib, is very different
from imaplib itself. Calling it a modified version from the standard
distribution is misleading. It's more like a complete rewrite. As
such, it's not really possible to summarize what was changed.

The largest thing is that imaplib2 is "threaded". Instead of doing
blocking writes/reads on the socket during/after every command,
imaplib2 forks off threads to read and write to the socket based on
input and output buffers. This opens the door to asynchronous
commands (every command is potentially asynchronous, according to the
docs), and in particular IDLE, which is by definition an asynchronous
command.

The author writes: "imaplib2 can be substituted for imaplib in
existing clients with no changes in the code", but that's pretty
misleading. It might be true for certain simple users of imaplib, but
for us it's completely false. Among other things, how untagged
responses are stored in-memory is different -- instead of a hash
table, it's a list. I'm guessing this is to preserve order of
responses.

I think there are other miscellaneous improvements, like I think
imaplib2 is IPv6 safe out-of-the-box, but I haven't conducted an
extremely thorough examination of the differences :)

2946a1ea5d Convert rfc822 module to email module
The rfc822 module has been deprecated since python 2.3, and conversion to
the email module is straightforward, so let us do that. rfc822 is

This also fixes a bug that led to offlineimap abortion (but that code path
is apparently usually not exercised so I did not notice:
rfc822|email.utils.parsedate return a tuple which has no named attributes,
but we were using them later in that function. So pass the tuple into a
struct_time() to get named attributes.

While reading the docs, I noticed that email.parsedate returns invalid
daylight savings information (is_dst attribute), and we are using it
anyway. Oh well, the imap server might think the mails are off by an hour
at worst.

efcce01d64 Declutter TTY output
Previously we would output:

Folder sync sspaeth.de[INBOX.INBOX201004]:
 Syncing INBOX.INBOX201004: IMAP -> Maildir
Folder sync sspaeth.de[INBOX.INBOX201006]:

Folder sync sspaeth.de[INBOX.INBOX201009]:
 Syncing INBOX.INBOX201009: IMAP -> Maildir

which is very repetitive and cluttered. By naming the folder sync
threads just according to the account and not the folder, the output
looks much nicer:

Folder sync [sspaeth.de]:
 Syncing INBOX.INBOX201004: IMAP -> Maildir
 Syncing INBOX.INBOX201006: IMAP -> Maildir
 Syncing INBOX.INBOX201009: IMAP -> Maildir

If syncing multiple accounts in parallel, we will still get headers
indicating the account:

Folder sync [sspaeth.de]:
 Syncing INBOX: IMAP -> Maildir
 Syncing INBOX.INBOX201006: IMAP -> Maildir
Folder sync [gmail]:
 Syncing INBOX: IMAP -> Maildir

This is a small fix that makes the output much nicer in my opinion.

Also don't output the thread name if we are in the MainThread, e.g. when
we output the initial offlineimap banner.
