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.

As reported by James Cook, we would not check the fingerprint of the SSL

Rather than using globals() though, I simply remove the by-now

import the SSL module in any case, so it needs to be there.

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 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

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).
Do not read in custom maildir flags, or we would try to sync them over
the wire. The next step will be to merge flag writes with existing
custom flags, so we don't lose information.
The long term goal will be to attempt to sync flags to the other side,
of course.

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.

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.

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.

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.

The readonly feature was introduced to safeguard repositories from

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

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.

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.

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).

set_abort_event and get_abort_event which can be used to set and check

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.

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.

* offlineimap/folder/IMAP.py (IMAPFolder.quickchanged,

EXISTS response on select(), so instead we use the return values from

* 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

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 :)

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.

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.

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

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

deprecated.

savemessage was too long and complex. Factor out the date guessing part

date guessing is the same, however, we do not use the
imaplib.Time2InternalDate() function as it is buggy
(http://bugs.python.org/issue11024) and returns localized patches. So we
create INTERNALDATE ourselves and pass it to append() as a string.

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.

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.

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).

Move the command line option handling from the more manual "getopts"
module to the full fledged "OptionParser". It has the advantage of
e.g. automatically creating the Help text that is shown with the
"-h/--help" option rather than having to hardcode the text and
format the line breaking manually.
Also, do away with the version check when invoking OfflineImap so we
do not have to change the version number in three places when bumping
it.
Rename startup() to run() which sounds more in line what other modules
call their run functions (e.g. Thread.run()).

Previoiusly, we would just bomb out with a KeyError("Foo") if a user
configured a repository Type=Foo. Or in case he tried to sync from a
Maildir to a Maildir. Still abort with an Exception now, but with one
that explains what actually had happened.

FYI: not sure if you all saw it or changed it, but there were three
places I always changed for each new release:
offlineimap.py
bin/offlineimap
offlineimap/version.py
in particular, the value in version.py must match the value in the
offlineimap(.py) file that someone uses to start the thing up.

Instead of repeating a mapping table twice, once for each direction, it is only
stored once. This is safer and faster.
As the patch stands, it makes no custom flags available. The behaviour

the cProfile/profile modules are great for performance debugging. The
pure-python profile module has much more overhead though and the
cProfile module is recommended if it exists. This changes to import to
first try the cProfile module and then fall back to the profile
module. The cProfile/profiles modules are API compatible for all that
its worth...
If that does not exist we continue to complain as before.

Rather than calling a function in a module, invoke offlineimap by
calling an OfflineImap object.
This removes code lying outside of objects; I prefer to keep code
within an object and provides us with a nicer Object encapsulation.
It will also ease the testing of Object functionality in unittests
when they are introduced.
Previously we would import and start Offlineimap like this:
from offlineimap import init
init.startup('6.2.0')
now we do:
from offlineimap import OfflineImap
offlineimap = OfflineImap()
offlineimap.startup('6.2.0')

This is very excessive and a bit annoying. Output that information
only if the next line concerns a different account/thread than the
previous one. This quiets down the UI quite a bit without losing
information.
While modifying this line, use the newer Thread.name and not the as
per python doc's old syntax getName()

Rather than poll our exitthread Queue in a non-blocking fashion and
always sleep for 1 second inbetween, simply call it in a blocking
fashion which will return immediately when a thread has exited. This
is somewhat faster as we don't do unnecessary sleeps after a thread
exited.
Do note that we need to specify some timeout value here (the 60 chosen
is pretty arbitary, but what the value exactly is, is not that
important, it could be any positive value) in order to make the
Queue.get() call work with SIGINT (cf
http://bugs.python.org/issue1360).

All other uis (especially BaseUI) define as warn(self, msg, minor = 0)

Change the X-OfflineIMAP header to work around possible Exchange MAPI
table overflow problem described in
http://article.gmane.org/gmane.mail.imap.offlineimap.general/1699
(It is unknown whether this problem still exits in current
Exchange versions, but let's assume the worst.)
The X-OfflineIMAP header is neccessary with some IMAP servers to
reliably determine the UID of a new messages uploaded to the server
by using the "UID SEARCH HEADER name string" command. Since this
command compares header name and value it is sufficient to have
a unique header value and a non-unique header name.
Note that a message can have more than one X-OfflineIMAP header if
the message was copied between IMAP folders multiple times.

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
After tens of thousands of messages on the IMAP server were deleted it
takes offlineimap extremely long time (several hours of high CPU usage)
to delete them locally. It spends almost all the time modifying
LocalStatus. It processes the messages one by one, rewriting the
folder's status file in LocalStatus after each message.
It is much more efficient to save the status file only once, after
removing all the messages from the messagelist.
Deleting lots of messages now takes seconds instead of hours.

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
Dear All,
Attached is the patch that I have developed to provide maxage and
maxsize options. You can thus sync only the last x days of messages and
exclude large messages. All details in the attached git file.

Subject: [PATCH] Patch to provide maxage and maxsize account options to exclude old/large messages
This is designed to make offlineimap even better for low bandwidth connections.
maxage allows you to specify a number of days and only messages within
that range will be considered by offlineimap for the sync. This can be
useful if you would like to start using offlineimap with a large
existing account and do not want to import large archives of mail.
maxsize allows you to specify the maximum size of a message to consider so
that you can exclude messages with large attachments etc.
In both cases the cachemessagelist function of the folder was modified to ignore
messages that do not meet the criteria. If the criteria are not specified
then the existing code will be executed the same as before. If a message
does not meet the criteria it will be as though this message does not exist
- offlineimap will completely ignore it. It will not have flags updated,
it will not be deleted, it will not be considered at all.
When operating against an IMAP repository a server side search function
is used. This of course requires support for server side search.
I have tested this with either option, no options etc. against IMAP, Maildir
and Gmail. I have run variations of this patch here for the last 3 weeks or
so syncing about 4 accounts normally.
This reverts commit 220db8a77d.

The documentation may have been unclear, but quick never worked the
way this patch changes it. My installed offlineimap does one sync
every $autorefresh minutes, and the $quick'th one is a full sync. All
the others are quick. Now it's going to do a full sync every
$autorefresh minutes and a ludicrous number of $quick syncs.

Hello John,
The attached patch makes quick synchronization work again (according to
the documentation), so there are <quick> quick synchronizations
performed between full synchronizations.
Thanks,

As encfs does not support hard linking, the rename of the temporary

This is the only occurrence of hard linking in offlineimap and can be
fixed by using an atomic `os.rename` instead of `os.link`+`os.unlink`.
I have been using the attached patch for more than 1.5 years and have
never again had any problems with offlineimap on encfs.

Good catch. I attach an updated patch which I've tested and it appears
to work fine, including not syncing two accounts twice.
