81fc20c7ca Remove python<2.6 import workarounds (set & ssl)
'set' is builtin since python2.6, so remove the imports. Also 'ssl' exists
since 2.6 and has everything we need, so no need for conditional import
tests here anymore.

006f19aba9 Make releaseconnection a NOOP when conn is None
During cleanup we often call releaseconnection in a finally: block. But

76b0d7cf25 imapserver: Make noop() more resitent against dropped connections.
Drop a connection, if the NOOP to keep a connection open fails due to
broken connections.

Note that I believe this function is not working as intended. We grab
one random connection and send a NOOP. This is not enough to keep all
connections open, and if we invoke this function multiple times, we
might well always get the same connection to send a NOOP through.

347e1eaa32 update CAPABILITIES after login
Some Webservers (I am looking at you Gmail) send different capabilities
before and after login, so they can tailor their server capabilities to
the user. While legal, this is uncommon and we were not updating our
server capabilities. Doing so allows us to detect that Gmail actually
supports the UIDPLUS extension, and we will stop mangling headers when
uploading to Gmail. This could lead to some performance gains when we
upload many messages to Gmail.

3a91e296f0 Adapt the code to work with the new imaplib2
imaplib renamed self.sslobj to self.sock and our overriden open()
functions were failing for that reason when updating imaplib2 to
v2.28. It turns out that all of our custom initializations are being
done by stock imaplib2 now anyway, so there is no need to override them
anymore. This lets us simplify the code we have to worry about.

Move the verifycert() function to the imapserver.py file, it is now a
callback function that is being handed to imaplib from there, so it
makes sense to also define it in our imapserver function...
(this also lets us easily make use of the verifycert function in the
starttls case in the future)

TODO: we need to examine if and why we still need to override the
select() function, it is the only reason why we still wrap the IMAP4
classes.

Remove a level of wrapper abstraction that is not needed. Just use
IMAPserver and be done with it.

We do this by passing in the IMAPRepository() instance rather than a
long list of single paramters to the IMAPServer instanciation. This way
we can retrieve all repository parameters ourselves, rather than passing
a dozen paramters into IMAPServer. Also, this enables us to pass the
repository() object into our WrappedIMAP4() instance, so that it can
query, e.g. the SSL fingerprint configuration.

7570f71880 Throw OfflineImapError when we try to request an inexistant message

only cache the list of UIDs in the beginning, we might be requesting
UIDs that don't exist anymore. Protect folder.IMAP.getmessage() against

Also, if the server responds with anything else than "OK", (eg. Gmail
seems to be saying frequently ['NO', 'Dave I can't let you do that now']
:-) so we should also be throwing OfflineImapErrors here rather than
AssertionErrors.

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

* offlineimap/imaplibutil.py: We override IMAP4_SSL.open, whose
  default arguments have changed, so update the default arguments. We

  relies on having a read_fd file descriptor to poll on.

f9413226b8 Import imaplib2 instead of imaplib
imaplib2 has slightly different semantics than standard imaplib, so
this patch will break the build, but I thought it was helpful to have it as
a separate commit.

b94bf79258 fix hang because of infinite loop reading EOF
Read() should return empty string when EOF happen, instead of looping
forever. This is the right semantics of read(), and a wrapped version
should not change it.

If you read the read(2) system call manpage, it tells you that when EOF
is seen, return value is 0; it does not say

	``loop forever when EOF happen''.

After the EOF detection is patched you can see the
following exception:

ab3900e479 Remove unneeded workaround for Darwin
There is a clumsy workaround for Darwin that chunks reads into 8kb
blocks to avoid huge memory allocations. First, this fix should not only
be required but on FreeBSD2.6 too (see
http://bugs.python.org/issue3531). Second, decent python versions (I
checked 2.6) already chunk in the SSL case anyway, so there is no need to do
that again. Remove that level of indirection.

http://evanjones.ca/python-memory.html claims that this problem has been
fixed since python 2.5, so we might consider removing the workaround
completely even for the non-SSL case.

Increase the chunk size on Mac from 8kb to 64kb. Even Macs should be
able to take that amount of memory usage nowadays.

0811beb03d Provide better error message for invalid 'reference' setting
When e.g. specifying an invalid 'reference' value for an IMAP server to
a root folder that does not exist, we would previously have crashed with
a nonsensical and non-intuitive error message (trying to address an
element of a NoneType).

This will also raise an Exception (which should be ok, given that this
is really a misconfiguration on the user side), but it will explain to
the user WHY it exited.

4f57b94e23 Implement SSL certificate checking
Previously, we did not check at all the authenticy and validity of
the SSL server we connected to. This is bad as it allows
man-in-the-middle attacks etc. This patch remedies the situation
somewhat.

If we specify a sslcacertfile= setting in the Repository section,
validate the server cert (on python>=2.6 or abort with python<=2.5).

As before, no certificate check is performed without that option.
In the future, the hostname check should be made optional and also
a mutt-lick "accept this certificate forever" thing should be
implemented.

9239a2d326 Bugfix patch for offlineimap
Hello John,

i fixed some tiny bugs in offlineimap, mainly just for myself. They are
more dirty fixes than real bugfixes since I'm missing the deeper insight
into the code.
Especially the first one for Curses.py is very dirty and breaks the
scaling of the interface when the terminal size changes, but at least
the terminal is in proper state after exiting offlineimap.

In the order of appearance in the patchfile:
1. 'fixes' terminal breakage on quit of curses interface in python 2.6
to 2.6.5 (fixed since 2.6.6 http://bugs.python.org/issue7567)
2. fixes netrc password authentication
3. fixes user name querying from netrc

The patch is made for git revision 6b1cb5e036

Thanks a lot for the great application!

Best regards,
buergi

30344587d9 Patch for error handling / separation of accounts etc.
Dear All,
I have made the attached patch to try and make offlineimap a bit more
stable in challenging situations.  It's extremely useful in slow
connection environments - but sometimes if one account had the wrong
password or the connection went down then unfortunately the whole
program would crash.

I have tested this on our connection and tried throwing at it just about
every situation - connection, up down, up, down again, change password,
error whilst copying one message, etc.  I have been running this patch
for the last 5 days or so syncing 6 accounts at the moment...  It seems
to work and stay alive nicely (even if your connection does not)...

Hope that this can go in for the next release... Please let me know if
anyone notices any problems with this...

Regards,

-Mike

Subject: [PATCH] This patch attempts to introduce a little more error handling - e.g.
 if one account has an error because of a changed password or something
 that should not affect the other accounts.

Specifically:
If one sync run has an issue this is in a try-except clause - if it
has an auto refresh period the thread will sleep and try again - this
could be quite useful in the event of the connection going down for a
little while, changed password etc.

If one folder cannot be created an error message will be displayed through
the UI and the program will continue (e.g. permission denied to create a folder)

If one message does not want to copy for whatever resaon an error message
will be displayed through the UI and at least the other messages will
be copied

If one folder run has an exception then the others will still run

817c09a460 Apply patch to fix autorefresh with Kerberos
Patch from Eric Dorland

Closes: #470875

From: Wouter Verhelst
Subject: kerberos authentication works only the first time
Date: Fri, 14 Mar 2008 09:28:37 +0100

Package: offlineimap
Version: 5.99.8
Severity: normal

Hi,

I have the "autorefresh" configuration option specified in my
.offlineimaprc, and am now using the kerberos authentication.

However, this kerberos authentication seems to work only the first
time
offlineimap tries to fetch mails. The next time, it fails with this
output:

fixes #20

 04/27/2008 09:34 AM - Vincent Beffara

    * File darwin.patch added

OK, I finally installed an IMAPS server on my iMac, so I could test a
little further. For some reason, fixing the read() method in
imaplibutil.py did not seem to work (it hung on connecting to the
server) - however, modifying the file imapserver.py similarly to the
non-SSL case fixed the crash.

I also reduced the chunk size to 100k instead of 1M, as 1M seemed to
still trigger the memory error in some cases. Ah, and I added a
platform test, so that the patch does essentially nothing on
non-Darwin machines ...

So, still no guarantee, but the attached patch works for me. Any
comments ?

(If noone here screams in horror at my code, I will include the patch
into the Fink package and see what happens there.)

Well it was a bit unclear but there's a patch for offlineimap attached
to Guido's message:

http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=10;filename=support-GSSAPI-via-pykerberos.diff;att=1;bug=359213

I've tried it out and it works great! Except that if the Kerberos
layer throws an exception it wouldn't fail over to plain
authentication properly. Attached is a slightly reworked patch that I
tested it in the following situations:

1. python-kerberos uninstalled, with kerberos credentials.
   Prompted for password authentication as expected.

2. python-kerberos installed, with kerberos credentials.
   Keberos authentication was successful and my mail was fetched
   without password prompting. Yeehaw!

3. python-kerberos installed, with no kerberos credentials.
   Prompted for    password authentication     as expected.

I think those are all the interesting situations. So I think this is
ready to go in, with a Suggest on python-kerberos (>=
1.0+mk080218-1).

Standard imaplib.py is really bad with this, since it reads one
