The three classes with names starting with UsefulIMAP4 were used for two
purposes, to include the UsefulIMAPMixIn class and to implement various
system-specific kludges. None of these kludges remain, so it is cleaner
to include UsefulIMAPMixIn directly in imaplibutil and forget about them
for good.

Now that we do not need any system-specific hack, the three UsefulIMAP4
classes have become empty and should be removed. This implies importing
UsefulIMAPMixIn directly from the classes defined in imaplibutil.
Prepare this change by moving the code into imaplibutil.py. Functionally
this is a no-op.

Because of a buggy realloc() implementation in earlier versions of
Python on Mac OS X, we had to cut reads into manageable chunks by hand;
this is no more needed with Python 2.6, and besides it causes problems
with imaplib2, which we now use. Revert the special case to use the
system's read() instead, which is now safe.

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.

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:

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.

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.

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.

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
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

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:
Thread 'Account sync Test' terminated with exception:

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.

* 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).
