ACC SHELL

###############################################################################
General

+ implement autoloading

+ add ability to override default port

+ get the URI modules in a releasable state

###############################################################################
Net::xAP

-------------------------------------------------------------------------------
B the mechanism that getline uses to stuff the literal payload into
  the string passed to parse_line needs to be improved.
  currently just tacks it onto the end.  maybe it should tack it into
  the end as a scalar ref and have parse_line look for '{\d+} SCALAR(.*)'.
  that should eliminate the chance of falsely interpreting {\d+} as a
  literal tag in instances where it isn't. make sure it derefs the
  scalar ref when it stuffs it into the list that is to be returned.
-------------------------------------------------------------------------------
B need to gracefully handle the server closing the connection without a bye

+ add methods for opening and closing a debug file as an alternative to stderr

B there are some things in IMAP that should be moved to xAP, and vice versa

B the addition of ACAP and IMSP might require the quotification to be
  revamped, with more direct control being moved into the subclasses

+ in synchronous mode, maybe have command failure synthesize a response
  object to alleviate the need to check status of the command method

+ add ability to selectively turn on or off debug for individual
  commands and callbacks

+ throw an error message when comment method is passed incorrect
  parameter count

+ documentation
  + document how top-level protocols should use xAP
###############################################################################
Net::IMAP

-------------------------------------------------------------------------------
B need to handle modified-utf-7 mailbox names correctly

B make the regex in _extract_resp_code more rigorous

B have callbacks do stronger arg checking in response data, particularly
  arg counts.

B clean up and test behavior when connection is terminated due to autologout
-------------------------------------------------------------------------------
+ maybe implement extensions as separate modules

+ force a LOGOUT if IMAP object goes out of scope

+ review various internet drafts to make sure they can be supported when RFCed
  + id		ok
  + sort	ok
  + thread	ok
  + children	ok
  + view	?
  + command+	?
  + annotate	?

B regression tests
  + extensions: namespace, acl, quota, uidplus
  + login and the various authentication extensions
  + lsub
  + more complete testing of quoted strings and literals
  + add more tests for fetched envelopes
  + verify Date option in append method (some servers may not honor it)
  + verify Flags option in append method (some servers may not honor it)
  + tests for imap2addr conversion methods
  + add ability to use non-local imap servers
  + test against cyrus, netscape, microsoft, innosoft

+ documentation
  + make sure the responses for extensions mention the appropriate extension
  + document the valid states for the various extension commands
  + document the response codes that need specific handling
  + add info about how to handle login and mailbox referrals
  + document which responses can be unsolicited
    + also mention what they indicate and when they are likely to be seen

+ add some more examples
-------------------------------------------------------------------------------
+ maybe have resp_codes have their own callbacks

+ write get_response that returns a list with the tag and rest of the
  response, instead of Net::IMAP::Envelope->new and Net::IMAP::FetchData->new

+ some response objects can be wired directly into parent Net::IMAP object
  + capability
  + flags
  + namespace
  + others...

B finish implementing authenticate command
  + add support for the security layer
  + figure out a reasonable way to hide auth info from debug command

+ add support for more extensions
  + login referrals
    + don't follow more than 10 referrals
  + mailbox referrals
  + idle
  + tls
  + various authentication extensions
    + otp
    + external
    + digest
    + gssapi
    + kerberos_v4

+ add ability to generate group lists in Net::IMAP::Address

+ maybe figure out a nice way to interface to Mail::Internet and MIME::Entity

+ implement smart EOL <-> crlf processing in append method
  check first line of string and adjust accordingly

B add support for X* commands

B implement and document prevention of ambiguous multiple pending requests
  + except for FETCH, STORE, and SEARCH, command must wait for a response
    before the following commands can be issued:
      FETCH, STORE, COPY, UID?, SEARCH (partially)
  + fetch -> store involving flags
  + select/examine -> select/examine
  + others, no doubt...

B add various items from IMAP Implementation Recommendations
  + look at limiting length of command lines through use of literals
  + don't SELECT a mailbox that has \noselect flag set
  + don't CREATE a submailbox in a mailbox that has \noinferiors flag set
  + don't respond to a failing COPY or APPEND with a CREATE if the
    server doesn't respond with a TRYCREATE response code
  + always put a trailing hierarchy delimiter in LIST reference argument
-------------------------------------------------------------------------------
+ write an interface for LWP (ala LWP::Protocol/ldap.pm)

+ decide whether X-NON-HIERARCHICAL-RENAME bug in cyrus imapd needs
  special handling

+ is there anything preventing module from being used in an off-line mode?

+ maybe implement the whole thing as two layers - the first layer is
  pure IMAP calls with minimal caching - the second layer uses cache
  information is it's available, only resorting to real imap calls if
  the data isn't cached

- maybe support older version of IMAP
###############################################################################
URI::imap

* need to write code for converting modified-utf7 <-> utf8

* need to do better job of preventing mutually exclusive url components
  (last one in wins)

* write regression test

* write documentation
-------------------------------------------------------------------------------
URI::acap

* write regression test

* write documentation
###############################################################################
Net::ACAP

* if it makes it into the release, remove the appropriate lines from
  the MANIFEST.SKIP file

* use the PAREN type in more places

* parse untagged condition responses

* response codes of interest to authentication failure:
  + auth-too-weak
  + encrypt-needed
  + transition-needed

* make sure xAP character set for autoquotification is correct for acap

* maybe coerse untagged ACAP response into an Acap object, otherwise
  get rid of Net::ACAP::Acap class

* figure out a way to take Return parm in search command into account
  when processing entry responses

* have deletedsince method accept an integer for its time parameter
  if length(timearg) >= 14 then its an acap time string, else its an integer

* have store method accept an integer for its unchangedsince parameter
  if length(timearg) >= 14 then its an acap time string, else its an integer

* UTF-8

+ spec limits size of an atom to 1024

+ NUL octets are only permitted in values of attributes whose names end with
  '.bin'.  client should send non-binary data as valid utf-8 data

+ context names must not start with '/'

+ need to handle extension responses

+ clients writing to a shared dataset SHOULD use UNCHANGEDSINCE when
  modifying an existing entry.

+ make sure any 'server SHOULD' items aren't a problem to the client
  if the 'server DOESNT'

+ clients MUST ignore unknown server responses which meet the syntax
  of response-extend or resp-code-ext

+ maybe include ability to cancel authentication exchange with a '*' line

+ tons more to do...

###############################################################################
Net::IMSP

* if it makes it into the release, remove the appropriate lines from
  the MANIFEST.SKIP file

* convert IMSP to use newer callback design

+ implement core commands
###############################################################################
Net::ICAP				Note: this will probably do away

+ implement core commands
