0752c123f5 Implement the "createfolders" setting for repositories
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

61e754c65e Do not try to release IMAP connection twice
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.

895e709bf2 Fix SSL fingerprint was not always checked
As reported by James Cook, we would not check the fingerprint of the SSL
server, as we were looking for the 'ssl' module in locals() rather than
globals(). Ooops!

Rather than using globals() though, I simply remove the by-now
superfluous check. We now rely on python2.6 and we unconditionally
import the SSL module in any case, so it needs to be there.

2f88b0296a Fix Curses interface for Python 2.6
In 2.6 all logging classes are not the new-style ones, so they
have no mro() method and, thus, we can't use super() for them.
Since CursesLogHanler is singly-inherited method, there will
be no problems in usage of the explicit superclass name.

IMAP, Maildir, and LocalStatus abort if in dry-run mode. IMAP and Maildir
will log that they "would have" created a new folder.

This will probably fail later on as we can not cache messagelists on
folder that don't exist, so --dry-run is not yet safe when new folders

ac033c68fd Improve nametrans local->remote folder syncing
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.

We were not cleaning out possibly existing APPENDUID messages before
APPENDing a new message. In case an old message were still hanging
around, this could *possibly* lead to retrieving and old UID. Things
should have been fine, but we do want to play safe here.

Also, make use of the "official" imaplib2 .response() command rather
than the internal _get_untagged_response() function.

Remove the hack that we would be looking for APPENDUID responses even if
the server claimed not to support the UIDPLUS ext. We now poll server
CAPABILITIES after login, and Gmail does provide us with the UIDPLUS
capability after login.

9453e1d955 Fix getuidvalidity crash (UIDVALIDITY returning None)
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.

There are more simplifications and improvements to be made.

344b2f0b7a TTYUI: Fix python 2.6 compatibility
We were using super() on a class derived from logging.Formatter() which
worked fine in python 2.7. Apparently python 2.6 uses old-style classes
for this, so the TTYUI broke and crashed OfflineImap. This was
introduced in OLI 6.5.0, I think.

Fix it by calling logging.Formatter.... directly, rather than the
elegant super() (which I happen to like a lot more than is appropriate
in the python world).

Reported by Nik Reiman as github issue 23, should fix that issue.

6dc74c9da5 Improve delete performance with SQLITE backend
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

3284e010ff Revert "use .response() rather _get_untagged_response()"
Recently the internal function use of imaplib2's _get_untagged_response()
was switched to use the public documented .response() function (which
should return the same data). However within a few fays we received reports
that both uses of a) the UIDVALIDITY fetching and b) the APPENDUID fetching
returned [None] as data although the IMAP log definitely shows that data
was returned. Revert to using the undocumented internal imaplib2 function,
that seemed to have worked without problems. This needs to be taken up to
the imaplib2 developer.

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).

8fc7227189 SEVERE: Fix getting wrong UID back on IMAP upload
This change looks harmless, but it fixes a severe bugfix, potentially
leading to data loss! It fixes the "on n new uploads, it will redownload
n-1, n-2, n-3,... messages during the next syncs" condition, and this is
what happens:

If there are more than one Mails to upload to a server, we do that by
repeatedly invoking folder.IMAP.savemessage(). If the server supports
the UIDPLUS extension we query the resulting UID by doing a:

imapobj._get_untagged_response('APPENDUID', True)

and that is exactly the problem. The "True" part causes the reply to
remain in the "response stack" of the imaplib2 library. When we do
the same call on a subsequent message and the connection is still on the
same folder, we will get the same UID response back (imaplib2 only looks
for the first matching response and returns that). The only time we
clear the response stack, is when the IMAP connection SELECTS a
different folder.

This means that when we upload 10 messages, the IMAP server gives us
always the same UID (that of the first one) back. And trying to write
out 10 different messages with the same UID will confuse OfflineIMAP.

This is the reason why we saw the ongoing UPLOADING/DOWNLOADING behavior
that people reported. And this is the reason why we saw the
inconsistency in the UID mapping in the IMAP<->IMAP case.

I urge everyone to upgrade ASAP. Sorry for that, I don't know why the
problem only became prevalent in the recent few releases as this code
has been there for quite a while.

de537dc09c Implement change_message_uid
Previously, assigning a new UID to a mapped IMAP or Maildir repository
was done by loading the "local" item, saving it under a new UID and
deleting the old one. This involved lots of disk activity for nothing
more than an effective file rename in Maildirs, and lots of network
usage in the MappedUID cases.

We do this on every upload from a local to a remote item, so that can
potentially be quite expensive. This patch lets backends that support it
(Maildir, MappedUID) efficiently rename the file rather than having to
read the mail content, write it out as a new file and delete the old
file. This speeds up uploads from Maildir and the MappedUID server.

d5666ce91d Don't create invalid maildir names with lower case maildir flags
If someone had a custom :2,a flag, adding a new flag would lead to the
invalid maildir filename ...a:2,... due to regex deficiencies not coping
with this. Fix this so we alway produce valid maildir names.

Note that custom flags are still problematic: as the syncing to the
remote IMAP server will fail, the next sync will assume that they have
been removed from the remote IMAP side and they will be removed from the
local Maildir then. We will need to think about how to handle this. At
least, with this patch we won't lose standard flags and won't produce
invalid maildir names.

74d580bc68 Exit "infinite" monitorloop when SyncRunner thread exits
The huge UI rework patch removed some obscure logic and special handling of
thread exit messages. It turns out that this was in fact still needed as a
specific exit message of the SyncRunner thread signified the threatmonitor
to quit.

We will want a nicer machinery for this in the future I guess, but fix the
eternal hang on exit by reintroducing a special exit message for the
SyncRunner thread, and return from the infinite monitor loop if SyncRunner
finishes.

Invalidate the folder cache when we create a folder during folder

slightly suboptimal from a performance point, but it is easy and will
lead to consistent results. Hopefully we will not have to create new
folders on each new run.

e145beb394 Fix "command CHECK illegal in state AUTH"
Dave identified a case where our new dropped connection handling did
not work out correctly: we use the retry_left variable to signify
success (0=success if no exception occured).

However, we were decrementing the variable AFTER all the exception
checks, so if there was one due to a dropped connection, it
could well be that we 1) did not raise an exception (because we want to
retry), and 2) then DECREMENTED retry_left, which indicated "all is
well, no need to retry".

The code then continued to check() the append, which failed with the
above message (because we obtained a new connection which had not even
selected the current folder and we were still in mode AUTH). The fix is
of course, to fix our logic: Decrement retry_left first, THEN decide
whether to raise() (retry_left==0) or retry (retry_left>0) which would
then correctly attempt another loop. I am sorry for this newbie type of
logic error. The retry count loop was too hastily slipped in, it seems.

1b6d76345a Robustify error msg against more failure
When syncfolder() fails, we output an error message containing the
foldername per the localfolder variable. However, the localfolder
variable is assigned inside our try: block and when the error occurs
there, we will have no localfolder variable to use for output. This
caused the errormsg to cause an Exception itself which unhelpfully
distracts from the root cause of the error.

it is guaranteed to work (by relying on parameters passed in to the
function).

c7938dc081 Per-account locking
Previously, we were simply locking offlineimap whenever it was
running. Howver there is no reason why we shouldn't be able to invoke it
in parallel, e.g. to synchronize several accounts in one offlineimap
each.

This patch implements the locking per-account, so that it is possible to
sync different accounts at the same time. If in refresh mode, we will
attempt to loop three times before giving up.

This also fixes Debian bug #586655

410e2d35e9 Set accountname in BaseFolder, and don't pass it in initialization
We passed in the accountname to all derivatives of BaseFolder, such as
IMAPFolder(...,repository,...,accountname), although it is perfectly
possible to get the accountname from the Repository(). So remove this
unneeded parameter. Each backend had to define getaccountname() (although
the function is hardly used and most accessed .accountname directly).

On the other hand BaseFolder was using getaccountname but it never defined
the function. So make the sane thing, remove all definitions from backends
and define accountname() once in Basefolder. It was made a property and not
just a (public) attribute, so it will show up in our developer
documentation as public API.

fe57140224 Fix repository 'readonly' configuration
The readonly feature was introduced to safeguard repositories from
accidental modifications. Unfortunately, my patch treated the readonly
setting as a string and not as a boolean, so if *anything* was set in
the configuration file as 'readonly', this value evaluated to True

Fortunately this was safe, we never treated a repository that we wanted
read-only as read-write. We always treated them readonly if something
was configured as "readonly=..." even if that was False.

The fix is simply to use getconfboolean() rather than getconf() which
checks for True/False/On/Off/yes/no/1/0 and hands back the correct boolean.

26721c60d4 Don't cache empty IMAP folders

no EXISTS response was given by the server at all.

Attempting to fetch the UIDs of 0 emails which leads to
various error messages (One server responds with "NO No matching
messages", Gmail seems to say "BAD Bad message sequence 1:*" for some
(although it is working fine for me with Gmail, so it might behave
different for different people).

popped up.

4db5913492 Use SafeConfigParser for the configuration
SafeConfigParser is very similar to the currently used ConfigParser but
it supports interpolation. This means values can contain format strings
which refer to other values in the same section, or values in a special
DEFAULT section. For example:

[My Section]
foodir: %(dir)s/whatever
dir=frob

would resolve the %(dir)s to the value of dir (frob in this case). All reference expansions are done on demand.

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.

9f23fea74e Fix error handling in folder.Base.copymessageto()
This is a bug fix on several levels. 1) We were lacking the import of
OfflineImapError. 2) OfflineImap.ERROR.MESSAGE was misspelled as ERROR.Message.
3) COntinuing with the next message only worked in single-thread mode
(using debug) and not in multi-thread mode. The reason is that we were
invoking a new thread and catching Exceptions in the main thread. But
python immediately aborts if an Exception bubbles up to a thread start.
This was fixed by catching exceptions directly in copymessageto() which
is the new thread, rather than catching them in the main thread.

select()ing rather than doing our own caching. Also remove the part
where we were setting the cache.

Just access self.state rather than looking up self.state via
self.getstate() every time, it is just an unnecessary layer of

fulls second in imaputil.debug() without even having debug output
enabled. imapsplit is mainly called by flagsplit() which will also do
debug output, so we get TONS of nearly duplicate debug output in the log
which makes it really hard to analyze.

Cut down the debug logging in imapsplit, we should be debug logging

3ce514e92b Simplify MappedIMAPFolder, fixing bugs
Previously, we instanciated an MappedImapFolder, and would cleverly (too
cleverly?) invoke methods on it casting it to an IMAPFolder by calling
methods such as: self._mb.cachemessages(self) where self._MB is the class
IMAPFolder and self and instance of MappedImapFolder. If
e.g. cachemessages() invokes a method uidexists() which exists for
MappedImapFolder, but not directly in IMAPFolder, I am not sure if
Python would at some point attempt to use the method of the wrong class.
Also, this leads to some twisted thinking as our class would in same
cases act as an IMAPFolder and in some cases as an MappedImapFOlder and
it is not always clear if we mean REMOTE UID or LOCAL UID.

This commit simplifies the class, by a)doing away with the complex Mixin
construct and directly inheriting from IMAPFOlder (so we get all the
IMAPFOlder methods that we can inherit). We instantiate self._mb as a
new instance of IMAPFolder which represents the local IMAP using local
UIDs, separating the MappedIMAPFolder construct logically from the
IMAPFolder somewhat.

In the long run, I would like to remove self._mb completely and simply
override any method that needs overriding, but let us take small and
understandable baby steps here.

Folder.savemessage() is supposed to return the new UID that a backend
assigned, and it BaseFolder.copymessageto() fails if we don't return a

For some reason, the UIDMappedFolder was not returning anything in

supposed to return a UID. Not sure how long this has already been the
case. This patch fixes the UIDMappedFolder to behave as it should.

d8026c5308 Simplify Maildir message saving
Previously we were attempting to save out mails according to
 http://www.qmail.org/man/man5/maildir.html in 4 steps:

1 Create a unique filename
2 Do stat(tmp/<filename>). If it found a file, wait 2 sec and go back to 1.
3 Create and write the message to the tmp/<filename>.
4 Link from tmp/* to new/*

(we did step 2 up to 15 times) But as stated by
http://wiki1.dovecot.org/MailboxFormat/Maildir (see section 'Issues with
the specification'), this is a pointless approach, e.g. there are race
issues between stating that the filename does not exist and the actual
moving (when it might exist).

So, we can simplify the steps as suggested in the dovecot wiki and
tighten up our safety at the same time.

One improvement that we do is to open the file, guaranteeing that it did
not exist before in an atomic manner, thus our simplified approach is
really more secure than what we had before.

Also, we throw an OfflineImapError at MESSAGE level when the supposedly
unique filename already exists, so that we can skip this message and
still continue with other messages.

b20f5192fb Allow to specify remote hostname even for the Gmail case
Previously we hard-coded the imap server name in the case of Gmail
repositories, but often we need a different host name. So, allow people
to specify the hostname via the regular "remotehosteval" and
"remotehost" settings, and only falling back to imap.gmail.com when
nothing has been specified.

Cache the hostname, so we don't evaluate the whole thing each time we
query the host name.

Make the remotehosteval processing more robust, by catching any
Exceptions that occur, and throw a OfflineImapError, that explains where
exactly the error had occured. You can test this, e.g. by setting
remotehosteval to 1/"n" or some other invalid expression.

The whole IMAP.gethost() function has been documented code wise while
going through.

1754bf4110 Allow to create the root MailDir directory
We currently do not allow nametrans rules such as
nametrans = lambda foldername: re.sub('^INBOX$', '', foldername)

because we crash with a traceback when running:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=499755

The underlying reason is that we cannot create the "top level" root
directory of the Maildir in the function makefolders(), it will bail
out. John Goerzen intentionally prevented offlineimap from creating the
top-level dir, so that a misconfiguration could not arbitrarily create
folders on the file system. I believe that it should be perfectly
possible to automatically create the root dirctory of the maildir. We
still protect against folder creations at arbitrary places in the file
system though.

This patch cleans up makefolders(), adds documentation, allows to
automatically create rootfolders if needed (using absolute paths) and
adds some robustness in case the folders already exist that we want to
create (rather than simply crapping out).

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. :-)

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.

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.

So we provide more efficient implementations for the uidexists()

UIDMapped case. This should solve the performance regression that was

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.

9a277cfd02 Remove a darwin-specific workaround for read()
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.

fd28c5a2d3 folder/IMAP: savemessage() should just save flags if uid already exists
As the LocalStatus and UIDMap backend already did: If the uid already
exists for savemessage(), only modify the flags and don't append a new
message.

We don't invoke savemessage() on messages that already exist in our sync
logic, so this has no change on our current behavior. But it makes
backends befave more consistent with each other.

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
completely gone in python3.

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]:
 Syncing INBOX.INBOX201006: IMAP -> Maildir
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.

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:

3eee821382 Simplify the syncing strategy a bit
The previous syncing strategy was doing more than we needed to and was a
bit underdocumented. This is an attempt to clean it up.

1) Do away with the previous different code paths depending on
whether there is a LocalStatus file or not (the isnewfolder() test). We
always use the same strategy now, which makes the strategy easier to
understand. This strategy is simply:

a) Sync remote to local folder first
b) Sync local to remote

Where each sync implies a 4 pass strategy which does basically the same
as before (explained below).

2) Don't delete messages on LOCAL which don't exist on REMOTE right at
the beginning anymore. This prevented us e.g. from keeping local
messages rather than redownloading everything once LocalStatus got
corrupted or deleted. This surprised many who put in an existing local
maildir and expected it to be synced to the remote place. Instead, the
local maildir was deleted. This is a data loss that actually occured to
people!

3) No need to separately sync the statusfolder, we update that one
simultanously with the destfolders...

3) Simplified the sync function API by only taking one destdir rather
than a list of destdirs, we never used more anyway. This makes the code
easier to read.

4) Added plenty of code comments while I was going through to make sure
the strategy is easy to understand.
-----------------------------------------

 Pass1: Transfer new local messages
        Upload msg with negative/no UIDs to dstfolder. dstfolder should
        assign that message a new UID. Update statusfolder.

 Pass2: Copy existing messages
        Copy messages in self, but not statusfolder to dstfolder if not
        already in dstfolder. Update statusfolder.

 Pass3: Remove deleted messages
        Get all UIDS in statusfolder but not self. These are messages
        that we have locally deleted. Delete those from dstfolder and
        statusfolder.

 Pass4: Synchronize flag changes
        Compare flags in self with those in statusfolder. If msg has a
        valid UID and exists on dstfolder (has not e.g.  been deleted
        there), sync the flag change to dstfolder and statusfolder.

The user visible implications of this change should be unnoticable
except in one situation:
 Blowing away LocalStatus will not require you to redownload ALL of
 your mails if you still have the local Maildir. It will simply recreate
 LocalStatus.

The previous ui names were pretty unwieldy. Is it TTYUI.TTY or

Simplify the names by making them case insensitive and by dropping
everything before the dot.

So "Curses.Blinkenlights" can now be invoked as "blinkenlights" or
"BLINKENLIGHTS". The old names will still work just fine so the
transition should be smooth. We issue a warning that the long names are
deprecated.

Document in offlineimap.conf that we don't accept lists of fallback UIs,
but only one UI option (this was already the case before this commit but
still wrongly documented).

The list of accepted ui names is:
  ttyui (default), basic, quiet, machineui, blinkenlights

419f27418e Simplify & document savemessage_getnewheader
savemessage_getnewheader was an undocmented, cryptic and overengineered
function. It generates a new unique value that can be used as a mail
header to be inserted. For this it used LOTS of randomness sources: hash
of the mail content, hash of the folder name, hash of the repository
name, the current time, a random() value, and the offlineimap version string.
All we need is something random. So reduce this to hash of content
appended by a random integer. Sufficient and somewhat faster to calculate.

Rename the function to actually describe accurately what it does or
would you have guessed that savemessage_getnewheader() did nothing more
than returning ('X-OfflineIMAP', <randomstring> )? Rename to
generate_randomheader() to make it clearer what this is all about.

Also document the function, describing what it does, and what it returns.

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.

93f7d0bd1f Enable debug output to see what folderfilter actually filters out
It is currently very hard to find out what folderfilter actually does
and makes it hard to debug for a user. With this patch if the user has
enabled "-d imap" (even better would perhaps be a different debug type
for this kind of thing?), we see a message
"Filtering out folder 'foo' due to folderfilter"
in the logs.

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.

472476db6f Remove over-verbose debug options
The debug output for dequote, optionsplit is very verbose, outputing
what the functions are called with and what they return. Those functions
are now very old mature and rather simple, so it suffices to output
their return value rather than cluttering out log with too much
uninteresting garbarge.

This makes log files much more readable.

d5e7620ce9 Create an abstract Repository class
A Repository() returns the correctly instanciated dervivate of a
BaseRepository, depending on the parameters passed to it. The returned
instance is eg an ImapRepository(). This makes the code look nicer,
and we have less functions lying around outside of classes (no more
global LoadRepository() function).

This will also enable us to conveniently hand back a
LocalStatusRepository based on SQLITE rather than plain text, if the
user configures this to be the experimental and optional backend
(once it exists).

Our thread pool should be made more robust against closed SSL

465af6c481 accounts.py: Merge AccountSynchronizationMixin with SyncableAccount class
AccountSynchronizationMixin was never used on its own and it is a very
confusing class until you understand what it is used for. (It
complemented the Account() class with a few methods to make Account()
syncable.

But we use the SyncableAccount class anyway, so merge the former Mixin'
methods directly in there.

This does away with a class that is not directly used, and was a case of
over-object-orientation which confuses more than it helps.

83a85bb3fb Remove MultiLock implementation
Currently the Curses code is broken. Importing offlineimap.ui.Curses
will not succeed due to cyclic imports (threadutils imports ui, but ui
wants threadutils.MultiLock). So Curses cannot be chosen.

Incidentally, the only part in the code that uses "MultiLock" is the
Curses UI, to prevent concurrent access from several threads to the
ui-internal thread list and to IO resources such as the
screen. Fortunately for these purposes we don't need a MultiLock, so we
can do away with that implementation completely. A simple RLock that
allows us to have a thread "own" a lock and makes other threads wanting
access to the resource wait until the owning thread is finished.

The MultiLock implementation looked a bit weird, so simplifying code
here is a good thing, it might well be that we fix some "hangs" that
have been reported (and that would only ever occur with the Curses UI).

760698253b LocalStatus: Don't ignore Exceptions on os.fsync
Earlier we would ignore *ALL* Exceptions that could occur during the
fsyncing of our LocalStatus database. Ignoring all Exceptions is not the
right thing here though. A recent commit improved the situation by
raising at least KeyboardInterrupt Exceptions, but that is still not
optimal.

os.fsync() is available on Unix, and Windows starting in python
2.2.3. so it should always work. If it doesn't, something is wrong.

It has been suggested to only catch EnvironmentError (ie SystemError and
OSError) here, but even those should be thrown. Something *is* wrong if
this fails and we should not ignore it.
