Our previous implementation of UID FETCH didn't ever take into account
maximum command line lengths. When fetching, say 800 messages from a
GMail IMAP server, we could easily overflow the max line length leading
to a fetch that didn't get all the messages we wanted to and was
truncated before the description of which fields we want. That caused
K-9 to fetch complete messages, exhaust memory and ultimately fail,
even when we were just trying to get message lengths.
An equivalent fix needs to be made to seach by UID.

whole mailbox before we let the user interact with the list is
increasingly painful. A 250 message mailbox takes 2+ seconds to "unlock"

Consequently, this commit switches us _back_ to progressive loading of
mailboxes from the synchronous version.

Update issue 662
We tried out the long press for a bit and deemed it too sensitive for general usage. It can cause problems with gestures and such, so I removed it again. I hope using the option menu is not too much overhead.
If you want to include it in your custom build or anything, then r 1976 and r1977 should be enough.

Added the long press initiation of text selection. I also noticed we'll have to make sure text selection is not recognized as a gesture (or at least ignored as gesture).
for sorting. This will prevent spam with ...less true dates from pushing
messages to the top of your list. Additionally, when downloading
messages from the server, they'll actually appear in the order they were
received - the existing behaviour really screwed up users who were
trying to triage mail as it came in.
The standard ScrollView causes problems when selecting text (and the message is long enough so scrolling is possible). The newly introduced ToggleScrollView can be set to disable scrolling via touch gestures thus making copying multi-line text sections possible.

Correct thread safety on some member variables when doing null checks.
Explicitly check for mMessageCount == -1 and stop=true in idling loop.
However, the original error message "Message count = -1 for folder"

Implements new setting "Sync remote deletions" which is checked by
default. When unchecked, K-9 Mail will no longer remove messages from
local storage just because the message was removed from the server.
This functionality works for all account types. Messages will still
be removed from the local store in order to stay within the limit
imposed by the "Number of messages to display" setting.

Issue 1643: Some servers respond with an untagged EXISTS to every

Issue 1664: I have never personally seen this error, and the log looks
like a thread safety problem. mMessageCount is being set in one

Utilize cketti's AutoSyncHelper in order to provide a way to make K-9

Fixes Issue 1577
Issue 1551:
Some IMAP servers send untagged EXPUNGEs to IDLEing
clients without ever haven't sent an untagged FETCH. The untagged
EXPUNGEs are harder to deal with because they don't have a UID. So,
if the user has elected to have the IDLE connection start with a poll,
we can maintain a map of message sequence numbers to UIDs that we can
use to figure out which message to delete. To mitigate the risk of
the map falling out of date, we do a UID SEARCH UID before removing
the local copy of the message, just to make sure the message is really
gone from the server. If we detect an error, do another poll to
resync the map.

When the remote store is incapable of returning an unread message count (POP)
or a flagged message count (POP, WebDAV), count the number of local
messages with the desired atributes.
Keep search results in sync with newly arrived or deleted messages.
Intentionally does not remove messages from search results due to
flag (flagged/starred or read/unread) state changes, because that
would be awkward while manipulating messages in search results.
When connected to a server that does not automatically send an

searchable folders, and the various search strategies.
Integration takes precedence over searchability. The Integrated Inbox
doesn't care about folder searchability. Nor does an unread or flag
search on specific folders.
Searches on specific accounts always go for displayable folders. That
might need to change so that searches on specific accounts can be on
DISPLAYABLE or ALL, but never NEVER. But in the current approach,
account-specific searches are done from the Accounts Activity, which
has an unread counter based on displayable non-special folders, so the
present implementation is the most logical for now.
interfering with "unread" searches on POP3 accounts.
Flags really should be normalized in the database to eliminate the use
of LIKE while searching by Flags.
Pass around simple Serializable MessageReference objects containing
account UUID, folder name and message UID so that MessageView can
traverse lists of messages which span folders and accounts.
Fixes ClassCastException.
Also:
Envelope and star in Accounts Activity are now both "hot". Tapping
the main part of the search opens the full search; tapping the
envelope opens the search only for unread messages; tapping the star
opens the search but only for starred messages.
The envelope and star are a bit small to reliably tap. Both options
should be available via long-press, also.
Methodology will be extended to real accounts, as well.
Fixes Issue 1431
Present flagged message count inside a star, matching the visual
presentation on individual messages.
Provide display of unread and flagged message counts for canned
searches.
Perhaps the message counts for searches and account size display
should be defeatable for improved speed.
Computing the account size is pretty slow for big accounts, and making
this functionality optional should be considered.
Also, displays the number of flagged messages ("stars") in each
account in the Accounts list and each folder in the FolderList. Needs
better presentation of the flagged message counts, but this works as a
proof-of-concept and gets the data structures built.
Look for + as acknowledgement that we're in IDLE mode, not "idling"
string.
Also, to help with battery life:
1) Give up trying to IDLE after 10 failures.
2) Increase retry delays
Not done, yet, but available for developers to use.
Definite things to be done in the short term:
1) Allow user to hide canned searches in Accounts Activity
2) Make newly arrived mail immediately appear in search results.
Possible improvements:
3) User-definable searches
4) Make newly deleted mail immediately disappear search results.
5) Make message with flag changes immediately appear/disappear from
search results.
6) Show search result size in Accounts Activity.
Fixes Issue 1126
Apply skisters2's patch for the POP notifications. Also, add another
setRingNotified at the beginning of each poll to make sure the account
is in the right state.
Allow user to turn off gesture-based control.
Also, consolidate so that gestures could be used by other subclasses
of K9Activity. Probably should be made usable to K9ListActivity, too,
by making MyGestureDetector its own class and make it used by
K9Activity and K9ListActivity, and have the Activities implement a
callback interface for onNext and onPrevious.
Provides for the user to elect to have certain folders displayed first
in the FolderList. Folders so elected are displayed in alphabetical
order first, then folders not so elected are displayed alphabetical
order.
No special handling is done for Inbox any more, except that it is in
"top group" by default, to preserve current behavior until the user
changes the settings.
Implement DEFLATE compression for IMAP communication, enabled by
default. User can disable compression for Wi-Fi, Mobile, or Other
networks, if it causes problems or if uncompressed communication is
faster, which is possible on Wi-Fi and wired networks, especially.
"Other" is to allow for the Android platform to introduce new
networking types without having to immediately change K-9 Mail.
However, as those arise, new network types should be added as explicit
types in K-9 Mail.

CAPABILITY command
2) When sent as an UNTAGGED response to LOGIN, updates stored

a) is already known if the server supports the NAMESPACE capability.
b) is included in the prefix anyway (=also known if namespace was set manually).
c) isn't needed when selecting a mailbox because we currently don't support folder hierarchy. So the delimeter is included in the folder name.
Fixes issue 1217
At cketti's suggestion, change the methodology for counting
server-side unread messages on an IMAP server from STATUS (UNSEEN) to
SEARCH UNSEEN NOT DELETED. STATUS (UNSEEN) does not ignore DELETED
but unexpunged messages and leads to incorrect results.

This variant only checks for unread messages in the last 300 messages
in the folder, so will be wrong if there are unread messages earlier
in the folder. However, it'll be more often correct than the old
version for the marjority of users.
Also, change the opening of folders for IMAP IDLE purposes to
read-only using EXAMINE instead of SELECT.
of the last successful periodic mail and computes the next start time
as an offset from that successful finish. The ramifications of this
new method is that changing polling interval on an account does not
force delaying all accounts to poll next in the future by the new
interval. Instead, K-9 Mail now adjusts the next poll time based on
what the next poll time should be based on the last poll finish and
the new interval.
Example 1: In the old way, if the old polling interval was 1 hour, and
the next poll was 50 minutes away (10 minutes have passed), and you
changed the interval to 15 minutes, the poll would happen 15 minutes
from now. In the new way, the next poll will happen only 5 minutes
from now, which is 15 minutes since the last poll.
Example 2: In the old way, if the old polling interval was 1 hour, and
the next poll was 10 minutes away (50 minutes have passed), and you
changed the interval to 30 minutes, the poll would happen 30 minutes
from now. The next poll would then happen actually 80 minutes after
the previous poll completed. In the new way, it'll actually happen
immediately, because the time for the next poll, based on the new
schedule, has already passed.
Similar scenarios happen when a loss of network connectivity
occurs. In the old way, polling would resume using the restoration of
connectivity as the starting point. Each time network connectivity
was lost and restored, the next poll would be further delayed. *If
connectivity was lost and restored frequently, a poll might never
happen!* In the new way, the next poll is rescheduled based on the
time of the last successful poll, so will be rescheduled just like it
was before the loss of connectivity. If the time has already been
passed, the poll will happen immediately.
Provide for setting Sent folder to -NONE- which suppresses actually
saving sent mail in any folder.
Also, eliminate logging which folders are not configured for pushing.
It was just too much logging.
Only reschedule polling and setup pushing when necessary due to
particular setting changes. Makes the K-9 Mail UI much more
responsive to setting changes that do not affect polling and pushing.
The poll schedule is deliberately only rescheduled when the period is
decreased. An increase in period will still allow the next scheduled
check to happen as originally scheduled.
