b6ede627a9 SQLite: make postponing transaction committing possible.
This should significantly improve performance when used to write large
amounts of messages.

This feature is enabled through the fsync configuration option.

Code refactorize around fsync.

This addresses #390 (although it doesn't necessarily fix all instances
of that problem yet).

2ac68d82aa UIDMaps: prevent from leaving a truncated map file
If the map file is not properly written (e.g. due to unexpected kill)
offlineimap might wrongly consider some UIDs to have been deleted from the local
side which could lead to data loss.

Use a temporary map file rather than writing to the map file directly.

a5ea1827fb folder: Base: sort message UID list
Return a sorted list of UIDs in getmessageuidlist.

Some MUAs (and their users) like to display messages in UID order
(or "order received").  If offlineimap is used in IMAP<->IMAP mode,
then the order messages are received by the second IMAP server will
be different because offlineimap iterates over a UID list produced
from the keys of a dictionary, which is unsorted.

This change sorts that list of UIDs so that both IMAP servers will
have their messages in the same order (except those times where
messages are appended to folders on both repositories between
syncs).

f634546980 explicitly set __hash__ of Base class to None
This suppressing the warning generated when running offlineimap on
python2 with -3 switch:

  offlineimap/folder/Base.py:29: DeprecationWarning: Overriding __eq__
  blocks inheritance of __hash__ in 3.x

Since this object is mutable it should not be hashable.

From Python documentation[1]:

  A class that overrides __eq__() and does not define __hash__() will
  have its __hash__() implicitly set to None.

Therefore old behaviour is preserved.

be285e522d IMAP: don't take junk data for valid mail content
OfflineIMAP frequently delivers mail files to the Maildir consisting exclusively
of a single ASCII digit in IDLE mode. IMAPFolder.getmessage expects 'data' to be
of the form

  [(fetch-info, message-body)]

However, the imapobj.uid call in getmessage returns a list of *all* pending
untagged FETCH responses.  If any message flags were changed in the selected
IMAP folder since the last command (by another client or another thread in
OfflineIMAP itself), the IMAP server will issue unsolicited FETCH responses
indicating these flag changes (RFC3501, section 7).  When this happens, 'data'
will look like, for example

  ['1231 (FLAGS (\\Seen) UID 5300)',
   '1238 (FLAGS (\\Seen) UID 5318)',
   ('1242 (UID 5325 BODY[] {7976}', message-body)]

Unfortunately, getmessage retrieves the message body as data[0][1], which in
this example is just the string "2", and this is what gets stored in the mail
file.

Multi-threaded OfflineIMAP with IDLE or holdconnectionopen is particularly
susceptible to this problem because flag changes synced back to the IMAP server
on one thread will appear as unsolicited FETCH responses on another thread if it
happens to have the same folder selected.  This can also happen without IDLE or
holdconnectionopen or even in single-threaded OfflineIMAP with concurrent access
from other IMAP clients (webmail clients, etc.), though the window for the bug
is much smaller.

Ideally, either imaplib2 or getmessage would parse the fetch responses to find
the response for the requested UID.  However, since IMAP only specifies
unilateral FETCH responses for flag changes, it's almost certainly safe to
simply find the element of 'data' that is a tuple (perhaps aborting if there is
more than one tuple) and use that.

1. There is one database per folder and sqlite requires to serialize the
writings. Instead of locking at LocalStatusSQLiteFolder object level, introduce
a new DatabaseFileLock object which is shared across threads. This fixes the
concurrent writes issues that some users might experience by duplications or
flags restored to the previous state.

2. Close the database only when we are sure no other threads will use the
connection on a *per-file* basis. Previous fix 677afb8d8f is wrong
because the same lock is shared for all the databases.

backend but this is still too early because autorefresh induces looping on this
code block.

Instead of delaying the closing outside of the loop, it's easier to delay the
opening as late as possible (inside the loop). The downside is that the database
is opened/closed more than once when autorefresh is enabled. The good news is
that this make the code much easier.

acc9c3cf49 introduce a virtual imaplib2
The virtual imaplib2 first try to import imaplib2 when provided by the system.
If not provided or if the version is not supported, fallback on the bundled
imaplib2 version.

Distribution maintainers can now easily remove the bundled imaplib2 version if
they want to get it packaged outside of offlineimap.

We still want to provide imaplib2 by default because:
- this library is neither in Python core nor packaged by a lot of distributions;
- users expect to be able to run offlineimap by just downloading the tarball or
  after a git clone.

In order to avoid unexpected (too old) versions of imaplib2, we restrict the
supported versions of this librabry.

23f96ba880 Encode utf-8 argument for md5 function
Python3 accepts binary input for md5 function.

This patch is known to break setups using folder names not strictly conforming
the IMAP UTF-7 encoding. We always made it clear that such setup is unsupported
and might be broken at some point in time. See documentation about
'decodefoldernames' in the provided configuration file. This is why this patch
is considered introducing no regression for this use case.

Patches to support both Python 3 and Python 2 by re-encoding the MD5 in the
filenames are welcome. This likely requires a new CLI option to allow
backporting the feature for users downgrading or changing of Python environment.

6b8ee4a183 Handle maxage for davmail correctly
"imapobj.search" returns a list with one string element of numbers
separated by one whitespace character for regular box (GMail, AOL...).
['1 2 3 4 5 6 7 8 9 10 11 12']
But if we would like to sync from Davmail it would return a list of
numbers.
['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12'].

The code "return res_data[0].split()" in the first case will return what
we already have when using Davmail, hence only one email will be
fetched.  But if only the first sync would be with maxage the emails
will be removed, because offlineimap will think that they were removed
by us.

The patch distinguishes between syncing with Davmail and regular box and
applies split on the first element only when it finds whitespace
character.  It also handles the case when the first element is empty on
first sync.

Closes #327

Introduce the '--migrate-fmd5-using-nametrans' option which migrates the

It seems that commit 'Apply nametrans to all Foldertypes' (6b2ec956cf)
introduced a regression because it changed the FMD5 part of the filename
calculated by OfflineIMAP. Thus, OfflineIMAP believes that the messages
has been removed and adds them back.

filename_use_mail_timestamp and utime_from_header are now completely

To handle this feature in a multithread context we use a hash to count

8096f6cd5b maxage: fix timezone issues, remove IMAP-IMAP support, add startdate option
1. When using maxage, local and remote messagelists are supposed to only
contain messages from at most maxage days ago. But local and remote used
different timezones to calculate what "maxage days ago" means, resulting
in removals on one side. Now, we ask the local folder for maxage days'
worth of mail, find the lowest UID, and then ask the remote folder for
all UID's starting with that lowest one.

2. maxage was fundamentally wrong in the IMAP-IMAP case: it assumed that
remote messages have UIDs in the same order as their local counterparts,
which could be false, e.g. when messages are copied in quick succession.
So, remove support for maxage in the IMAP-IMAP case.

3. Add startdate option for IMAP-IMAP syncs: use messages from the given
repository starting at startdate, and all messages from the other
repository. In the first sync, the other repository must be empty.

4. Allow maxage to be specified either as number of days to sync (as
previously) or as a fixed date.

25513e9038 fix: don't loose local mails because of maxage
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.

Now we, when extracting the labels from a message, we read all label
headers, instead of just the first one.

This has the consequence that some old labels stored locally in a second
X-Keywords (or third...) header, which effectively was rendered
invisible to offlineimap until now, may pop back up again and be pushed
to gmail. No labels will be removed by the changes in this commit,
though.

aef88cc1f8 Fix label processing in GmailMaildir
Commit 7df765cfdb introduced regression:
GmailMaildir caches labels in its own function and it was testing the
presence of the 'labels' key in message descriptor.  But 7df765cf
changed descriptor initialization and this key is always present.

So now we have 'labels_cached' flag that tells us if labels were
already cached or not.

For cases like
  http://article.gmane.org/gmane.mail.imap.offlineimap.general/6468
it is beneficial to see that folder name was translated and the result
of this translation on a single line: having log like
{{{
Folder Boring/Wreck [acc: tmarble@info9.net]:
 Syncing Boring/Breck: Gmail -> Maildir
}}}
with translated name on the "Folder" line and original one on the
"Syncing" line isn't very intuitive.

For servers without UIDPLUS we are inserting additional header
just after transformation '\n' -> CRLF was done.  addmessageheaders()

1690e5f74e Copymessageto should not be private since we override it
private methods prevent them from being overriden on derived classes. In
GmailFolder we need to override copymessageto, so it can't be private.

Before this commit, copymessageto was made private in Base but not in
GmailFolder. The end result was that labels were not set when copying
the message content, and always needed to be set on the label copying
pass.

1b954c3b4c Add ability to migrate status data across backends
If when we request a LocalStatus folder, the folder has to be created,
we look whether the other backend has data, and if it does we migrate
it to the new backend.

The old backend data is left untouched, so that if you change back say
from sqlite to plaintext, the older data is still there.  That should
not lead to data loss, only a slower sync while the status folder gets
updated.

214137eb7b Improvements to the SQlite-based local status folder
* Do not inherit LocalStatusSQLiteFolder class from the plaintext
    one.

  * Use some functions already in BaseFolder in both, plaintext and
    sqlite classes.

  * Add a saveall method. The idea is that saveall dumps the entire
    messagelist to disk, while save only commits the uncommited
    changes. Right now, save is noop for sqlite, and equivalent to
    saveall for plaintext, but it enables to be more clever on when we
    commit to disk in the future.

09556d645e Adapt plain status folder to gmail labels stuff
* Implements Status Folder format v2, with a mechanism to upgrade an
    old statusfolder.

  * Do not warn about Gmail and GmailMaildir needing sqlite backend
    anymore.

  * Clean repository.LocalStatus reusing some code from
    folder.LocalStatus.

  * Change field separator in the plaintext file from ':' to '|'. Now
    the local status stores gmail labels. If they contain field
    separator character (formerly ':'), they get messed up. The new
    character '|' is less likely to appear in a label.

0e4afa9132 Make GmailFolder sync GMail labels
When synclabels config flag is set to "yes" for the GMail repo,
offlineimap fetches the message labels along with the messages, and
embeds them into the body under the header X-Keywords (or whatever
'labelsheader' was set to), as a comma separated list.

It also adds an extra pass to savemessageto, that performs label
synchronization on existing messages from GMail to local, the same way
it is done with flags.

We also introduce GmailMaildir repository that adds functionality to
change message labels.  It keeps track of messages modification time,
so one can quickly detect when the labels may have changed.
