synchronization could happen if an Exception was thrown while parsing
an untagged response without using executeSimpleCommand. For
instance, while doing a fetch. Once synchronization was lost, later
commands would fail in surprising ways. One manifestation of such
failures was spontaneously emptying of folders when search results
were not returned properly. The new code makes sure to only accept OK
responses with the tag of the command, and discards the untagged
responses from previous command.

394: Replace code change lost with move of DAmail MailService.java to
K-9. Eliminate the stopSelfs. Without the stopSelfs, the Service
remains active and the Android platform is far less likely to kill the
process, although not absolutely forbidden from doing so. Better will
be to implement the full BroadcastReceiver methodology referred to in
Issue 394, which would allow replacing the stopSelfs, which would make
K-9 a better good citizen.
252: Fix logic for raising and canceling notifications based on number
of new unread messages and total unread messages.

Handle untagged EXISTS messages at any time. Should increase
synchronization speed and accuracy.
Handle IMAP servers that send a NIL where a literal is normally.
Avoids failure to sync when folder contains certain messages.
Throw Exception if folder message count is less than 0, avoiding
accidentally emptying a folder.
Issue 192
Do not remove markers for deleted messages, even if the corresponding
remote message is not returned by the remote store. The remote
message may not be returned simply because the query did not encompass
it on this run. If the account's delete policy is set to "Do not
delete from server", or the delete hasn't succeeded before a folder
refresh, a message for which the deleted marker has been removed can
errorneously reappear.
This will lead to the local store eventually having a large number of
deleted message markers. In the long term, we'll need a way to manage
and possibly automatically remove them.
Merged from branch issue143 @ revision 426:
Complete replacement for SharedPreferences. Uses SQLite database
stored in application's databases folder.
Will load from legacy preferences if DB-backed preferences are empty.
Editor conforms to atomic commit contract.
Hardening of POP3 and SMTP communication:
SMTP: Decrement failure counter when no possible message send
occurred. This way, K-9 will only stop attempting to send messages
for which a possible successful send occurred, but K-9 could not
detect. Any message that is known to have completely failed to send
will be reattempted indefinitely.
POP3: Some reworking of Exception handling. Also, if it is not
possible to get a "message number" for the UID of the message that is
being deleted, conclude that the message has already been deleted on
the server. Mark this as a permanent error, so that it gets removed
from the pending actions queue.
MessagingController: Look for the permanentFailure flag on the
MessagingException, and if a pending action raised a permanent
failure, remove the pending action from the queue so that it will not
be re-attempted nor block later requests.
Significant hardening of the email sending process.
A given message in the Outbox is only attempted to be sent 5 times.
Once the threshold is reached, the message is flagged. asses through
the Outbox skip flagged messages. The message can be tried again by
manually unflagging. When any messages are flagged during a pass
through the Outbox, K-9 raises a notification with a fast flashing red
LED, alerting the user to the failure to send. A note is also placed
in the K9mail-errors.
The read timeout on SMTP connections has been changed to 300000ms (5
minutes)
The send attempt counter is kept in memory, not stored with the
message, so a phone or application restart will clear the counters,
but not the flagged state. As the intent of this revision is to avoid
runaway message sending, this is deemed to be acceptable for now.
The moving of messages from the Outbox to the Sent folder has been
changed to an atomic move.
Extra error checking has been added to the SMTP communication code.
The flashing LED may be excessive.
Provide preference for which folder is automatically expanded when
entering the Folder/Message list.

Android Email.
Fails to move the automatically opened folder to the top of the

The already selected folder should be highlighted (or otherwise

*All "Check mail" options, except for the long-press on an individual
folder, respect the normal synchronization class settings.
Eliminate all Refresh menu items.
Add progress indicators to Accounts activity. Indeterminite progress

One change of my own, putting the actual folders name outside the
parentheses, and the functional/special name inside the parentheses.
Copy now copied body (but attachments might not work right).
Move is now reliable (needed to open the destination folder), and
leaves a placeHolder message behind in the source folder so that
messages are not resynced.
3.
Each remote Store (IMAP, POP3, WebDAV) can provide indications to the
higher level classes as to whether copy and move are implemented.
Currently, copy and move are only provided by ImapStore.java. When
the facilities are not available, the user interface suppresses the
menu options.
The available destination folders can be configured using folder
classes.
Copy results in null message bodies in the destination copy of the
message until the next sync. This is a problem that occurred with
deletes previously, and is likely a fault with the copyMessages method
of LocalStore.java.
Utilizes a modified version of the ChooseFolder.java Activity that
debuachedsloth contributed in a patch attached to Issue 285 on 16 Feb
2008.
All messages in all folders that were sent from the email address
associated with the account display the recipient, preceeded by To:,
instead of the sender.
Puts quotes around username and password for IMAP authentication.
Also, if authentication fails, closes the connection so that it will
be retried. Otherwise, there is no way to fix the problem, say, by
changing the password in the Incoming Settings.
ConcurrentHashMap seems to serialize as a HashMap. Not sure why or
how.
This change has re-enabled the saving of the unread counts during an
orientation change, giving somewhat fast response. If it fails again,
just comment out the block of code.
Provide two options for each Account:
Compact (which VACUUMs the accounts and prunes recreatable
attachments)
Clear all data (danger!) (which wipes all messages and attachments in
the account, except placeholder deleted messages)
Displays a Toast when the Compact or Clear is queued, and another
Toast with the shrinkage results.
(Also, a small change to increase probability of seeing messages after
a sync, by setting the needsRefresh on all folders when a sync is done.)

Push unread message counting into the background.
Should increase startup performance and reduce black-screens-of-death

Also, updates the per-account unread message count when email account

folders are sorted first by subject, then by date. Subject sorting is
case insensitive and disregards leading re:, fw: and fwd: prefixes.
Threading can be toggled via the T hotkey or the option menu.
The icons could use improvement.
Threading state is maintained during a run of K-9, among all

Re-enable instant deletes in MessageView
Deleted message suppression should be generalized into a flag cache,
serving Seen, Flagged, and Answered flags, as well.
Copy message to Trash still needs work, so that no duplicates are ever
visible and server-sync is more clean. This will be especially
important, as the same code will be needed for the future "message
copy/move" facility.
Account settings) for scrolling the navigation buttons with the
message, or keeping the buttons on screen. Scrolling mode can be
automatically switched based on availability of keyboard. (Issue 197
and Issue 194)
Add ability to flag/unflag message from options menu
1) Eliminate the top row Next Message and Previous Message
2) In the bottom buttons for portrait mode, replace Reply and Forward
with Prev and Next
Justification: if you're going to be replying or forwarding, you're
about to embark on a lot of typing, anyway. Having to hit Menu
isn't an undue burden.
3) Prev goes to the adjacent *older* message, next goes to the
adjacent *newer* message
4) In the bottom buttons for landscape mode, added Prev and Next as the
outer buttons
5) Add Account option for hiding the bottom buttons when the keyboard
is available.
Also, temporarily (hopefully!) reverted the instant delete from the
MessageView because it isn't working right. The method here is slower
but safer.
date/time formats. With this change, K-9 can run on original master
or cupcake versions for the platform.
This seems like an excessive amount of code. Perhaps there is a
public API that accomplishes this work. Alternatively, the code in
MessageView.java and FolderMessageList.java should be consolidated
into a utility class used by both of the classes needing this
functionality.

a red/bold subject. Can be done in the FolderMessageList using the
hotkey G (toggle) or by long-pressing the message to bring up the
message context menu. Can be done while viewing an individual message
by using the hotkey G (toggle). To-do: add a Flag/Unflag option to a
menu in the individual message view.
Add sending the Answered flag to the IMAP server when replying to a
message. This is currently done as soon as the reply is started.
Perhaps it would be better to wait until the reply is sent, but that
would require keeping additional state with the draft. Messages to
which the user has replied are indicated with a white arrow next to
the subject.
To-do: In the MessageView, provide visual indication of Flagged and
Answered states.
