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.

If APPEND raises abort(), the (typ, dat) variables will not be set, so
we should not be using it for the OfflineImapError Exception
string. Fixing and prettifying the string formatting a bit at the same

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.
Reconstruct the folder name in a bit more complex way, but in a way so
it is guaranteed to work (by relying on parameters passed in to the
function).

Hi, the following patch updates the documentation. It was a bit out of

Also, the code for the helper functions is available there under

of python code in the manual which seems weird.

nametrans rules can lead to different visiblename names for the
top-level directory, specifically both '.' and '' (the latter was
recently introduced). However, we need to be able to compare folder
names to see if we need to create a new directory or whether a directory
already exists, so we need to be able to compare a repositories
visiblename (=transposed via nametrans rule) with another folder.
To make the top-level directory comparison happen, we enforce a
top-level name of '', so that comparisons work.

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.

Commit b0e88622c4 changed dst_hash[folder.visiblename] to
dst_hash[folder.name] but we did not adapt all places where it is needed
to use visiblename again. This led to attempting to create a name on
REMOTE ignoring the nametrans setting on the LOCAL repository.
Signed-off-by: Sebastian Spaeth <Sebastian@SSpaeth.de>
Previously, we only checked if a LOCAL folder falls under the local
repositories folderfilter rule when deciding whether a folder should be
created on REMOTE.
However, we also do not want to create the folder on REMOTE if it would
fall under a folderfilter rule there. This patch prevents us from doing
so.

If nametrans translates to an empty directory we want to find the

Previously, getfolder() would always construct new MaildirFolder()
objects, independent of whether the folder exists or not. Improve the
function to:
1) Scan and cache the folders if not already done
2) Return the same cached object if we ask for the same foldername twice
3) Reduce a tiny bit of code duplication
This is important because we handle stuff like folderfilter in the
scandir function and if we discard the scanned dir and create a new
object on folderget(), we will lose the folderfilter information.

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.

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.
