Suppose messages A and B were delivered to the remote folder at
"maxage + 1" days ago.
A was downloaded to the local folder "maxage + 1" days ago, but B was only
downloaded "maxage - 1" days ago (contrived scenario to illustrate the two
things that could happen). The behavior was that B gets deleted from the local
folder, but A did not. The expected behavior is that neither is deleted.
Starting where Base.py: __syncmessagesto_delete(self, dstfolder, statusfolder)
is called where:
- self is the remote folder
and
- dstfolder is the local folder.
It defines deletelist to be the list of messages in the status folder
messagelist that aren't in the remote folder messagelist with
not self.uidexists(uid)
A and B are both in the status folder. They're also both *NOT* in the remote
folder messagelist: this list is formed in IMAP.py: cachemessagelist(), which
calls _msgs_to_fetch(), which only asks the IMAP server for messages that are
"< maxage" days old.
Back to Base.py __syncmessagesto_delete(), look at the call
folder.deletemessages(deletelist), where folder is the local folder. This ends
up calling Maildir.py deletemessage() for each message on the deletelist. But we
see that this methods returns (instead of deleting anything) if the message is
in the local folder's messagelist. This messagelist was created by Maildir.py's
cachemessagelist(), which calls _scanfolder(), which tries to exclude messages
based on maxage. So at this point, we *WANT* A and B to be excluded -- then they
will be spared from deletion. This maxage check calls _iswithinmaxage(), and
actually does the date comparison based on the time found at the beginning of
the message's filename. These filenames were originally created in Maildir.py's
new_message_filename(), which calls _gettimeseq() to get the current time (i.e.
the time of retrieval).
Upshot: A's filename has an older timestamp than B's filename. A is excluded
from the local folder messagelist in _scanfolder(), hence spared from deletion
in deletemessage(); B is not excluded, and is deleted.
This patch does not address the timezone issue. As for the IMAP/timezone issue,
a similar issue is discussed in the thunderbird bug tracker here:
https://bugzilla.mozilla.org/show_bug.cgi?id=886534
In the end, they're solving a different problem, but they agree that
there is really no reliable way of guessing the IMAP server's internal
timezone.

This simplifies logics for the user, especially if he uses both

is requested.
See

Default CA bundle is requested via 'sslcertfile = OS-DEFAULT'.
I had also enforced all cases where explicitely-requested CA bundles
are non-existent to be hard errors: when users asks us to use CA
bundle (and, thus, certificate validation), but we can't find one,
we must error out rather than happily continue and downgrade to

Now we, when extracting the labels from a message, we read all label

This has the consequence that some old labels stored locally in a second

The problem lies in the fact that offlineimap.folder.Base's method
syncmessagesto_copy() uses threaded code everytime it is suggested by
the derived class's suggeststhreads() (currently, only IMAP does this
suggestion), but offlineimap/init.py will not spawn the
exitnotifymonitorloop() from offlineimap.threadutil.
The root cause is that ExitNotifyThread-derived threads need
offlineimap.threadutil's exitnotifymonitorloop() to be running the
cleaner for the exitthreads Queue(), because it fills the queue via
the run() method from this class: it wants to put() itself to the
Queue on exit, so when no exitnotifymonitorloop() is running, the
queue will fill up. And if this thread is an instance of
InstanceLimitedThread that hits the limit on the number of threads,
then it will hold the instancelimitedsems[] semaphore will prevent
other InstanceLimitedThread()s of the same name to pass its start()
method.

offlineimap has several frontends that encourage running it from a
terminal under an X session. When X session closes for a system
shutdown, the terminals exit, after sending SIGHUP to their children.
Previously SIGHUP was treated to be equivalent to SIGUSR1, i.e. wake
up and sync all accounts. This causes delays during shutdown.
According to Wikipedia [0], SIGHUP has been repurposed from a
historical meaning to one of:
* re-read configuration files, or reinitialize (e.g. Apache, sendmail)
* controlling pseudo or virtual terminal has been closed
I believe second meaning is more appropriate for offlineimap, and
hence this patch makes SIGHUP to be handled in the same way SIGTERM
and SIGINT are handled.

Fix imapfolder.getmessageinternaldate misparsing the Date:
header from emails due to a bug or surprising behaviour by
email.utils.parsedate. This is because email.utils.parsedate's
return value contains the unadjusted hour value from the string
parsed but does not include information about the time zone in
which it is specified. For example (Python 2.7.3):
$ python -c "import email.utils;
print email.utils.parsedate('Mon, 20 Nov 1995 19:12:08 -0500')"
(1995, 11, 20, 19, 12, 8, 0, 1, -1)
(the -1 is the isdst field); the -0500 time zone is completely
ignored, so e.g. the same input with time "19:12:08 +0300" has
the same result. When passed to time.struct_time as allowed per
the parsedate documentation, this time is interpreted in GMT and
thus deviates from the correct value by the timezone offset
(in this example, -5 hours).
I consider this a bug in email.utils.parsedate: In my opinion,
since the return value of the parsetime doesn't include a timezone,
it should be expressed in terms of UTC rather than in terms of the
time zone from the Date header; the existence of
email.utils.parsedate_tz, to which I've switched, indicates that
maybe the authors were aware of this problem.

If we ask twice for a LocalStatusFolder via getfolder(), we would
get a newly created instance each time. This can lead to problems,
as e.g. write locks protecting files only work within the same Folder
instance. Make it so, that we cache all Folder instances that we have
asked for and hand back the existing one if we ask again for it,
rather than recreate a new instance.
Also, make getfolders() a noop for LocalStatus. We attempted to
derive the foldername from the name of the LocalStatusfile. However,
this is not really possible, as we do file name mangling
(".$" -> "dot", "/" -> ".") and there is no way to get the original folder
name from the LocalStatus file name anyway.
This commit could potentially solve the "file not found" errors, that people
have been seeing with their LocalStatusCache files. If we have 2
instances of a LocalStatusFolder pointing to the same file, our locking
system would not work.

banner to the file. This was never intended. Quiet should be really quiet
unless it experiences an error. Simplify the logging statement, to do nothing
if logevel is set to "WARNING" aka quiet.

If 'readonly' is True, folders shouldn't be created (regardless of
'createfolders' option). With old behavior, instead folders were always created
when 'readonly' is True (even if 'createfolders' was also False), which is a
serious bug (offlineimap was creating folders in all read-only repositories).
'createfolders' should only play a role if 'readonly' is False, in which case
folders should only be created if 'createfolders' is True.

As Gmail was only announcing the presence of the UIDPLUS extension
after we logged in, and we were then only getting server
capabilities before, a hack was introduced that checked the
existence of an APPENDUID reply, even if the server did not claim
to support it.
However, John Wiegley reports problems, where the APPENDUID would
be None, and we attempt to go this path (it seems that imaplib2
returns [None] if there is no such reply, so our test here for "!="
might fail. Given that this is an undocumented imaplib2 function
anyway, and we do fetch gmail capabilities after authentication,
this hack should no longer be necessary.
We had problems there earlier, where imapobj.response() would
return [None] although we had received a APPENDUID response from
the server, this might need more debugging and testing.

By default OfflineImap propagates new folders in both
directions. Sometimes this is not what you want. E.g. you might want
new folders on your IMAP server to propagate to your local MailDir,
but not the other way around. The 'readonly' setting on a repository
will not help here, as it prevents any change from occuring on that
repository. This is what the `createfolders` setting is for. By
default it is `True`, meaning that new folders can be created on this
repository. To prevent folders from ever being created on a
repository, set this to `False`. If you set this to False on the
REMOTE repository, you will not have to create the `Reverse
nametrans`_ rules on the LOCAL repository.
Also implement a test for this

Reported by sharat87 in https://github.com/spaetz/offlineimap/pull/38,
he would often get an unhandled Exception when trying to
releaseconnection() a connection that was not in the pool of
connections.
The reason this could happen is that when folder.IMAP.quickchanged()
raises an Exception in select(), we would release the connection in the
"except" handling, and than release the same connection in the "finally"
clause, which led to the error. The right thing is to only release the
connection once, of course.

While improving the test suite, I noticed that we would not create folders on
the remote in some cases when we should (yay for test suites!). This is because
we were testing the untransposed LOCAL foldername and check if it existed on
the remote side when deciding whether we should potentially create a new folder.
Simplify the code by transposing the LOCAL folder names in dst_hash, saving us
to create another confusing "newsrc" temp variable. Make the code a bit more
readable by using dst_name_t to indicate we operate a transposed folder name.
This now passes test 03 (using invalid nametrans rules) when test 03 would pass
before.

Rename getuidvalidity -> get_uidvalidity and cache the IMAP result.
1) Start modernizing our function names using more underscores
2) IMAPs implementation of get_uidvalidity was removing the UIDVALIDITY result
from the imaplib2 result stack, so subsequent calls would return "None".
As various functions can invoke this, this led to some errors that we
avoid by caching the current UIDVALIDITY value in the Folder instance.

We were using super() on a class derived from logging.Formatter() which

Fix it by calling logging.Formatter.... directly, rather than the

in the python world).

When deleting many (eg 2000) mails using the SQLITE backend, this takes
a long time durig which OfflineImap can not be aborted via
CTRL-C. Thinking it had frozen permanently, I killed it hard, leaving a
corrupted db journal (which leads to awkwards complaints by OLI on
subsequent starts!). That shows that delete performance is critical and
needs improvement.
We were iterating through the list of messages to delete and deleted
them one-by-one execute()'ing a new SQL Query for each message. This
patch improves the situation by allowing us to use executemany(), which
is -despite still being one SQL query per message- much faster. This is
because rather than performing a commit() after each mail, we now do
only one commit() after all mails have been deleted.

Subject: [PATCH] Only scan children in _getfolders_scandir if extension is set.
When sep is '/', MaildirRepository._getfolders_scandir recursively
checks sub-directories for additional maildirs. The old loop logic
always checked the top directory and its children. This lead to
children being found twice, once from their parent, with dirname
matching their directory name, and once from themselves, with a
dirname of ''.
This patch fixes the problem by only checking the top directory when
extension is not set (i.e. for the root directory).
