NAME
Net::OSCAR - Implementation of AOL's OSCAR protocol for instant
messaging (for interacting with AIM a.k.a. AOL IM a.k.a. AOL Instant
Messenger - and ICQ, too!)
SYNOPSIS
use Net::OSCAR qw(:standard);
sub im_in {
my($oscar, $sender, $message, $is_away) = @_;
print "[AWAY] " if $is_away;
print "$sender: $message\n";
}
$oscar = Net::OSCAR->new();
$oscar->set_callback_im_in(\&im_in);
$oscar->signon($screenname, $password);
while(1) {
$oscar->do_one_loop();
# Do stuff
}
INSTALLATION
HOW TO INSTALL
perl Build.PL
perl Build
perl Build test
perl Build install
See "perldoc Module::Build" for details. Note that this requires that
you have the perl module Module::Build installed. If you don't, the
traditional "perl Makefile.PL ; make ; make test ; make install" should
still work.
DEPENDENCIES
This modules requires "Digest::MD5" and "Scalar::Util". "Test::More" is
needed to run the test suite, and "XML::Parser" is needed to generate
the XML parse tree which is shipped with released versions.
INTRODUCTION
ABSTRACT
"Net::OSCAR" implements the OSCAR protocol which is used by AOL's AOL
Instant Messenger service. To use the module, you create a "Net::OSCAR"
object, register some functions as handlers for various events by using
the module's callback mechanism, and then continually make calls to the
module's event processing methods.
You probably want to use the ":standard" parameter when importing this
module in order to have a few important constants added to your
namespace. See "CONSTANTS" below for a list of the constants exported by
the ":standard" tag.
No official documentation exists for the OSCAR protocol, so it had to be
figured out by analyzing traffic generated by AOL's official AOL Instant
Messenger client. Source code from the Gaim client, the protocol
analysis provided by the Ethereal network sniffer, and the website
<http://iserverd1.khstu.ru/oscar/> were also used as references.
This module strives to be as compatible with "Net::AIM" as possible at
the API level, but some protocol-level differences prevent total
compatibility. The TOC protocol implemented by "Net::AIM" is simpler
than OSCAR and has official reference documentation from AOL, but it
only provides a small subset of the full "OSCAR" functionality. See the
section on "Net::AIM Compatibility" for more information.
EVENT PROCESSING OVERVIEW
Event processing is the implementation of "Net::OSCAR" within the
framework of your program, so that your program can respond to things
happening on the OSCAR servers while still doing everything else that
you need it to do, such as accepting user input. There are three main
ways for the module to handle event processing. The simplest is to call
the do_one_loop method, which performs a "select" call on all the
object's sockets and reads incoming commands from the OSCAR server on
any connections which have them. The "select" call has a default timeout
of 0.01 seconds which can be adjusted using the timeout method. This
means that every time you call do_one_loop, it will pause for that
interval if there are no messages from the OSCAR server. If you need
lower overhead, want better performance, or need to handle many
Net::OSCAR objects and/or other files and sockets at once, see
"HIGH-PERFORMANCE EVENT PROCESSING" below.
FUNCTIONALITY
"Net::OSCAR" pretends to be WinAIM 5.5.3595. It supports remote
buddylists including permit and deny settings. It also supports chat,
buddy icons, and extended status messages. At the present time, setting
and retrieving of directory information is not supported; nor are email
privacy settings, voice chat, stock ticker, file transfer, direct IM,
and many other of the official AOL Instant Messenger client's features.
TERMINOLOGY
When you sign on with the OSCAR service, you are establishing an OSCAR
session.
CALLBACKS
"Net::OSCAR" uses a callback mechanism to notify you about different
events. A callback is a function provided by you which "Net::OSCAR" will
call when a certain event occurs. To register a callback, calling the
"set_callback_callbackname" method with a code reference as a parameter.
For instance, you might call "$oscar->set_callback_error(\&got_error);".
Your callback function will be passed parameters which are different for
each callback type (and are documented below). The first parameter to
each callback function will be the "Net::OSCAR" object which generated
the callback. This is useful when using multiple "Net::OSCAR" objects.
REFERENCE
BASIC FUNCTIONALITY
METHODS
new ([capabilities => CAPABILITIES])
Creates a new "Net::OSCAR" object. You may optionally pass a hash to
set some parameters for the object.
capabilities
A listref of optional features that your client supports. Valid
capabilities are:
extended_status
iChat-style extended status messages
buddy_icons
file_transfer
file_sharing
typing_status
Typing status notification
$oscar = Net::OSCAR->new(capabilities => [qw(extended_status typing_status)]);
signon (HASH)
signon (SCREENNAME, PASSWORD[, HOST, PORT]
Sign on to the OSCAR service. You can specify an alternate host/port
to connect to. The default is login.oscar.aol.com port 5190.
The non-hash form of "signon" is obsolete and is only provided for
compatibility with "Net::AIM". If you use a hash to pass parameters
to this function, here are the valid keys:
screenname
password
Screenname and password are mandatory. The other keys are
optional. In the special case of password being present but
undefined, the auth_challenge callback will be used - see
"auth_challenge" for details.
stealth
Use this to sign on with stealth mode activated. Using this, as
opposed to signon on without this setting and then calling
"set_stealth", will prevent the user from showing as online for
a brief interval after signon. See "set_stealth" for information
about stealth mode.
pass_is_hashed
If you want to give Net::OSCAR the MD5 hash of the password
instead of the password itself, use the MD5'd password in the
password key and also set this key. The benefit of this is that,
if your application saves user passwords, you can save them in
hashed form and don't need to store the plaintext.
local_ip
If you have more than one IP address with a route to the
internet, this parameter can be used to specify which to use as
the source IP for outgoing connections.
host
port
proxy_type
Either "SOCKS4", "SOCKS5", "HTTP", or HTTPS. This and
"proxy_host" must be specified if you wish to use a proxy.
"proxy_port", "proxy_username", "proxy_password" are optional.
Note that proxy support is considered experimental. You will
need to have the "Net::SOCKS" module installed for SOCKS
proxying or the "LWP::UserAgent" module installed for HTTP
proxying.
proxy_host
proxy_port
proxy_username
proxy_password
If the screenname is all-numeric, it will automatically be treated
as an ICQ UIN instead of an AIM screenname.
signoff
Sign off from the OSCAR service.
CALLBACKS
signon_done (OSCAR)
Called when the user is completely signed on to the service.
BUDDIES AND BUDDYLISTS
See also "OTHER USERS" for methods which pertain to any other user,
regardless of whether they're on the buddylist or not.
METHODS
findbuddy (BUDDY)
Returns the name of the group that BUDDY is in, or undef if BUDDY
could not be found in any group. If BUDDY is in multiple groups,
will return the first one we find.
commit_buddylist
Sends your modified buddylist to the OSCAR server. Changes to the
buddylist won't actually take effect until this method is called.
Methods that change the buddylist have a warning about needing to
call this method in their documentation. After calling this method,
your program MUST not call it again until either the buddylist_ok or
buddylist_error callbacks are received.
rollback_buddylist
Revert changes you've made to the buddylist, assuming you haven't
called "commit_buddylist" since making them.
reorder_groups (GROUPS)
Changes the ordering of the groups in your buddylist. Call
"commit_buddylist" to save the new order on the OSCAR server.
reorder_buddies (GROUP, BUDDIES)
Changes the ordering of the buddies in a group on your buddylist.
Call "commit_buddylist" to save the new order on the OSCAR server.
rename_group (OLDNAME, NEWNAME)
Renames a group. Call "commit_buddylist" for the change to take
effect.
add_buddy (GROUP, BUDDIES)
Adds buddies to the given group on your buddylist. If the group does
not exist, it will be created. Call "commit_buddylist" for the
change to take effect.
remove_buddy (GROUP, BUDDIES)
See add_buddy.
add_group (GROUP)
Creates a new, empty group. Call "commit_buddylist" for the change
to take effect.
remove_group (GROUP)
See add_group. Any buddies in the group will be removed from the
group first.
groups
Returns a list of groups in the user's buddylist.
buddies (GROUP)
Returns the names of the buddies in the specified group in the
user's buddylist. The names may not be formatted - that is, they may
have spaces and capitalization removed. The names are
"Net::OSCAR::Screenname" objects, so you don't have to worry that
they're case and whitespace insensitive when using them for
comparison.
buddy (BUDDY[, GROUP])
Returns information about a buddy on the user's buddylist. This
information is a hashref as per "USER INFORMATION" below.
set_buddy_comment (GROUP, BUDDY[, COMMENT])
Set a brief comment about a buddy. You must call "commit_buddylist"
to save the comment to the server. If COMMENT is undefined, the
comment is deleted.
set_buddy_alias (GROUP, BUDDY[, ALIAS])
Set an alias for a buddy. You must call "commit_buddylist" to save
the comment to the server. If ALIAS is undefined, the alias is
deleted.
CALLBACKS
buddy_in (OSCAR, SCREENNAME, GROUP, BUDDY DATA)
SCREENNAME (in buddy group GROUP) has signed on, or their
information has changed. BUDDY DATA is the same as that returned by
the buddy method.
buddy_out (OSCAR, SCREENNAME, GROUP)
Called when a buddy has signed off (or added us to their deny list.)
buddylist_error (OSCAR, ERROR, WHAT)
This is called when there is an error commiting changes to the
buddylist. "ERROR" is the error number. "WHAT" is a string
describing which buddylist change failed. "Net::OSCAR" will revert
the failed change to its state before "commit_buddylist" was called.
Note that the buddylist contains information other than the user's
buddies - see any method which says you need to call
"commit_buddylist" to have its changes take effect.
buddylist_ok (OSCAR)
This is called when your changes to the buddylist have been
successfully commited.
PRIVACY
"Net::OSCAR" supports privacy controls. Our visibility setting, along
with the contents of the permit and deny lists, determines who can
contact us. Visibility can be set to permit or deny everyone, permit
only those on the permit list, deny only those on the deny list, or
permit everyone on our buddylist.
METHODS
add_permit (BUDDIES)
Add buddies to your permit list. Call "commit_buddylist" for the
change to take effect.
add_deny (BUDDIES)
See add_permit.
remove_permit (BUDDIES)
See add_permit.
remove_deny (BUDDIES)
See add_permit.
get_permitlist
Returns a list of all members of the permit list.
get_denylist
Returns a list of all members of the deny list.
visibility
Returns the user's current visibility setting. See set_visibility.
set_visibility (MODE)
Sets the visibility mode, which determines how the permit and deny
lists are interpreted. Note that if you're looking for the feature
which will prevent a user from showing up as online on any buddy
list while not affecting anything else, the droids you're looking
for are "is_stealth"/"set_stealth".
The visibility mode may be:
* VISMODE_PERMITALL: Permit everybody.
* VISMODE_DENYALL: Deny everybody.
* VISMODE_PERMITSOME: Permit only those on your permit list.
* VISMODE_DENYSOME: Deny only those on your deny list.
* VISMODE_PERMITBUDS: Same as VISMODE_PERMITSOME, but your permit
list is made to be the same as the buddies from all the various
groups in your buddylist (except the deny group!) Adding and
removing buddies maintains this relationship. You shouldn't
manually alter the permit or deny groups when using this
visibility mode.
These constants are contained in the "Net::OSCAR::Common" package,
and will be imported into your namespace if you import "Net::OSCAR"
with the ":standard" parameter.
When someone is permitted, they can see when you are online and send
you messages. When someone is denied, they can't see when you are
online or send you messages. You cannot see them or send them
messages. You can talk to them if you are in the same chatroom,
although neither of you can invite the other one into a chatroom.
Call "commit_buddylist" for the change to take effect.
is_stealth
set_stealth STEALTH_STATUS
These methods deal with "stealth mode". When the user is in stealth
mode, she won't show up as online on anyone's buddylist. However,
for all other purposes, she will be online as usual. Any
restrictions, imposed by the visibility mode (see "set_visibility"),
on who can communicate with her will remain in effect.
Stealth state can be changed by another signon of the user's
screenname. So, if you want your application to be aware of the
stealth state, "is_stealth" won't cut it; there's a
"stealth_changed" callback which will serve nicely.
set_group_permissions (NEWPERMS)
Set group permissions. This lets you block any OSCAR users or any
AOL users. "NEWPERMS" should be a list of zero or more of the
following constants:
GROUPPERM_OSCAR
Permit AOL Instant Messenger users to contact you.
GROUPPERM_AOL
Permit AOL subscribers to contact you.
Call "commit_buddylist" for the change to take effect.
group_permissions
Returns current group permissions. The return value is a list like
the one that "set_group_permissions" wants.
OTHER USERS
See also "BUDDIES AND BUDDYLISTS".
METHODS
get_info (WHO)
Requests a user's information, which includes their profile and idle
time. See the buddy_info callback for more information.
get_away (WHO)
Similar to get_info, except requests the user's away message instead
of their profile.
send_im (WHO, MESSAGE[, AWAY])
Sends someone an instant message. If the message is an automated
reply generated, perhaps, because you have an away message set, give
the AWAY parameter a non-zero value. Note that "Net::OSCAR" will not
handle sending away messages to people who contact you when you are
away - you must perform this yourself if you want it done.
Returns a "request ID" that you can use in the "im_ok" callback to
identify the message. If the message was too long to send, returns
zero.
send_typing_status (RECIPIENT, STATUS)
Send a typing status change to another user. Send these messages to
implement typing status notification. Valid values for "STATUS" are:
* TYPINGSTATUS_STARTED: The user has started typing to the
recipient. This indicates that typing is actively taking place.
* TYPINGSTATUS_TYPING: The user is typing to the recipient. This
indicates that there is text in the message input area, but
typing is not actively taking place at the moment.
* TYPINGSTATUS_FINISHED: The user has finished typing to the
recipient. This should be sent when the user starts to compose a
message, but then erases all of the text in the message input
area.
evil (WHO[, ANONYMOUSLY])
"Evils", or "warns", a user. Evilling a user increases their evil
level, which makes them look bad and decreases the rate at which
they can send messages. Evil level gradually decreases over time. If
the second parameter is non-zero, the evil will be done anonymously,
which does not increase the user's evil level by as much as a
standard evil.
You can't always evil someone. You can only do it when they do
something like send you an instant message.
get_icon (SCREENNAME, MD5SUM)
Gets a user's buddy icon. See set_icon for details. To make sure
this method isn't called excessively, please check the
"icon_checksum" and "icon_timestamp" data, which are available via
the buddy method (even for people not on the user's buddy list.) The
MD5 checksum of a user's icon will be in the "icon_md5sum" key
returned by buddy.
You should receive a buddy_icon_downloaded callback in response to
this method.
CALLBACKS
new_buddy_icon (OSCAR, SCREENNAME, BUDDY DATA)
This is called when someone, either someone the user is talking with
or someone on their buddylist, has a potentially new buddy icon. The
buddy data is guaranteed to have at least "icon_checksum" available;
"icon_timestamp" and "icon_length" may not be. Specifically, if
"Net::OSCAR" found out about the buddy icon through a buddy status
update (the sort that triggers a buddy_in callback), these data will
not be available; if "Net::OSCAR" found out about the icon via an
incoming IM from the person, these data will be available.
Upon receiving this callback, an application should use the
"icon_checksum" to search for the icon in its cache, and call
get_icon if it can't find it. If the "icon_md5sum", which is what
needs to get passed to get_icon, is not present in the buddy data,
use get_info to request the information for the user, and then call
get_icon from the buddy_info callback.
buddy_icon_downloaded (OSCAR, SCREENNAME, ICONDATA)
This is called when a user's buddy icon is successfully downloaded
from the server.
typing_status (OSCAR, SCREENNAME, STATUS)
Called when someone has sent us a typing status notification
message. See send_typing_status for a description of the different
statuses.
im_ok (OSCAR, TO, REQID)
Called when an IM to "TO" is successfully sent. REQID is the request
ID of the IM as returned by "send_im".
im_in (OSCAR, FROM, MESSAGE[, AWAY])
Called when someone sends you an instant message. If the AWAY
parameter is non-zero, the message was generated as an automatic
reply, perhaps because you sent that person a message and they had
an away message set.
buddy_info (OSCAR, SCREENNAME, BUDDY DATA)
Called in response to a get_info or get_away request. BUDDY DATA is
the same as that returned by the buddy method, except that one of
two additional keys, "profile" and "awaymsg", may be present.
THE SIGNED-ON USER
These methods deal with the user who is currently signed on using a
particular "Net::OSCAR" object.
METHODS
email
Returns the email address currently assigned to the user's account.
screenname
Returns the user's current screenname, including all capitalization
and spacing.
is_on
Returns true if the user is signed on to the OSCAR service.
Otherwise, returns false.
profile
Returns your current profile.
set_away (MESSAGE)
Sets the user's away message, also marking them as being away. If
the message is undef or the empty string, the user will be marked as
no longer being away. See also "get_away".
set_extended_status (MESSAGE)
Sets the user's extended status message. This requires the
"Net::OSCAR" object to have been created with the "extended_status"
capability. Currently, the only clients which support extended
status messages are Net::OSCAR, Gaim, and iChat. If the message is
undef or the empty string, the user's extended status message will
be cleared. Use "get_info" to get another user's extended status.
set_info (PROFILE)
Sets the user's profile. Call "commit_buddylist" to have the new
profile saved into the buddylist, so that it will be set the next
time the screenname is signed on. (This is a Net::OSCAR-specific
feature, so other clients will not pick up the profile from the
buddylist.)
Note that Net::OSCAR stores the user's profile in the server-side
buddylist, so if "commit_buddylist" is called after setting the
profile with this method, the user will automatically get that same
profile set whenever they sign on through Net::OSCAR. See the file
"PROTOCOL", included with the "Net::OSCAR" distribution, for details
of how we're storing this data.
Use "get_info" to retrieve another user's profile.
set_icon (ICONDATA)
Sets the user's buddy icon. The "Net::OSCAR" object must have been
created with the "buddy_icons" capability to use this. "ICONDATA"
must be less than 4kb, should be 48x48 pixels, and should be BMP,
GIF, or JPEG image data. You must call commit_buddylist for this
change to take effect. If "ICONDATA" is the empty string, the user's
buddy icon will be removed.
When reading the icon data from a file, make sure to call "binmode"
on the file handle.
Note that if the user's buddy icon was previously set with
Net::OSCAR, enough data will be stored in the server-side buddylist
that this will not have to be called every time the user signs on.
However, other clients do not store the extra data in the buddylist,
so if the user previously set a buddy icon with a
non-Net::OSCAR-based client, this method will need to be called in
order for the user's buddy icon to be set properly.
See the file "PROTOCOL", included with the "Net::OSCAR"
distribution, for details of how we're storing this data.
You should receive a buddy_icon_uploaded callback in response to
this method.
Use "get_icon" to retrieve another user's icon.
change_password (CURRENT PASSWORD, NEW PASSWORD)
Changes the user's password.
confirm_account
Confirms the user's account. This can be used when the user's
account is in the trial state, as determined by the presence of the
"trial" key in the information given when the user's information is
requested.
change_email (NEW EMAIL)
Requests that the email address registered to the user's account be
changed. This causes the OSCAR server to send an email to both the
new address and the old address. To complete the change, the user
must follow instructions contained in the email sent to the new
address. The email sent to the old address contains instructions
which allow the user to cancel the change within three days of the
change request. It is important that the user's current email
address be known to the OSCAR server so that it may email the
account password if the user forgets it.
format_screenname (NEW FORMAT)
Allows the capitalization and spacing of the user's screenname to be
changed. The new format must be the same as the user's current
screenname, except that case may be changed and spaces may be
inserted or deleted.
set_idle (TIME)
Sets the user's idle time in seconds. Set to zero to mark the user
as not being idle. Set to non-zero once the user becomes idle. The
OSCAR server will automatically increment the user's idle time once
you mark the user as being idle.
CALLBACKS
admin_error (OSCAR, REQTYPE, ERROR, ERRURL)
This is called when there is an error performing an administrative
function - changing your password, formatting your screenname,
changing your email address, or confirming your account. REQTYPE is
a string describing the type of request which generated the error.
ERROR is an error message. ERRURL is an http URL which the user may
visit for more information about the error.
admin_ok (OSCAR, REQTYPE)
This is called when an administrative function succeeds. See
admin_error for more info.
buddy_icon_uploaded (OSCAR)
This is called when the user's buddy icon is successfully uploaded
to the server.
stealth_changed (OSCAR, NEW_STEALTH_STATE)
This is called when the user's stealth state changes. See
"is_stealth" and "set_stealth" for information on stealth.
extended_status (OSCAR, STATUS)
Called when the user's extended status changes. This will normally
be sent in response to a successful set_extended_status call.
evil (OSCAR, NEWEVIL[, FROM])
Called when your evil level changes. NEWEVIL is your new evil level,
as a percentage (accurate to tenths of a percent.) ENEMY is undef if
the evil was anonymous (or if the message was triggered because your
evil level naturally decreased), otherwise it is the screenname of
the person who sent us the evil. See the "evil" method for more
information on evils.
EVENT PROCESSING
METHODS
do_one_loop
Processes incoming data from our connections to the various OSCAR
services. This method reads one command from any connections which
have data to be read. See the timeout method to set the timeout
interval used by this method.
process_connections (READERSREF, WRITERSREF, ERRORSREF)
Use this method when you want to implement your own "select"
statement for event processing instead of using "Net::OSCAR"'s
do_one_loop method. The parameters are references to the readers,
writers, and errors parameters used by the select statement. The
method will ignore all connections which are not
"Net::OSCAR::Connection" objects or which are
"Net::OSCAR::Connection" objects from a different "Net::OSCAR"
object. It modifies its arguments so that its connections are
removed from the connection lists. This makes it very convenient for
use with multiple "Net::OSCAR" objects or use with a "select"-based
event loop that you are also using for other purposes.
See the selector_filenos method for a way to get the necessary bit
vectors to use in your "select".
CALLBACKS
connection_changed (OSCAR, CONNECTION, STATUS)
Called when the status of a connection changes. The status is "read"
if we should call "process_one" on the connection when "select"
indicates that the connection is ready for reading, "write" if we
should call "process_one" when the connection is ready for writing,
"readwrite" if "process_one" should be called in both cases, or
"deleted" if the connection has been deleted.
"CONNECTION" is a "Net::OSCAR::Connection" object.
Users of this callback may also be interested in the
"get_filehandle" method of "Net::OSCAR::Connection".
CHATS
METHODS
chat_join (NAME[, EXCHANGE])
Creates (or joins?) a chatroom. The exchange parameter should
probably not be specified unless you know what you're doing. Do not
use this method to accept invitations to join a chatroom - use the
"chat_accept" method for that.
chat_accept (CHATURL)
Use this to accept an invitation to join a chatroom.
chat_decline (CHATURL)
Use this to decline an invitation to join a chatroom.
CALLBACKS
chat_buddy_in (OSCAR, SCREENNAME, CHAT, BUDDY DATA)
SCREENNAME has entered CHAT. BUDDY DATA is the same as that returned
by the buddy method.
chat_buddy_out (OSCAR, SCREENNAME, CHAT)
Called when someone leaves a chatroom.
chat_im_in (OSCAR, FROM, CHAT, MESSAGE)
Called when someone says something in a chatroom. Note that you
receive your own messages in chatrooms unless you specify the
NOREFLECT parameter in chat_send.
chat_invite (OSCAR, WHO, MESSAGE, CHAT, CHATURL)
Called when someone invites us into a chatroom. MESSAGE is the
message that they specified on the invitation. CHAT is the name of
the chatroom. CHATURL is a chat URL and not a
"Net::OSCAR::Connection::Chat" object. CHATURL can be passed to the
chat_accept method to accept the invitation.
chat_joined (OSCAR, CHATNAME, CHAT)
Called when you enter a chatroom. CHAT is the
"Net::OSCAR::Connection::Chat" object for the chatroom.
chat_closed (OSCAR, CHAT, ERROR)
Your connection to CHAT (a "Net::OSCAR::Connection::Chat" object)
was severed due to ERROR.
MISCELLANEOUS
METHODS
timeout ([NEW TIMEOUT])
Gets or sets the timeout value used by the do_one_loop method. The
default timeout is 0.01 seconds.
loglevel ([LOGLEVEL[, SCREENNAME DEBUG]])
Gets or sets the level of logging verbosity. If this is non-zero,
varing amounts of information will be printed to standard error
(unless you have a "log" callback defined). Higher loglevels will
give you more information. If the optional screenname debug
parameter is non-zero, debug messages will be prepended with the
screenname of the OSCAR session which is generating the message (but
only if you don't have a "log" callback defined). This is useful
when you have multiple "Net::OSCAR" objects.
See the "log" callback for more information.
auth_response (MD5_DIGEST[, PASS_IS_HASHED])
Provide a response to an authentication challenge - see the
"auth_challenge" callback for details.
clone
Clones the object. This creates a new "Net::OSCAR" object whose
callbacks, loglevel, screenname debugging, and timeout are the same
as those of the current object. This is provided as a convenience
when using multiple "Net::OSCAR" objects in order to allow you to
set those parameters once and then call the signon method on the
object returned by clone.
buddyhash
Returns a reference to a tied hash which automatically normalizes
its keys upon a fetch. Use this for hashes whose keys are AIM
screennames since AIM screennames with different capitalization and
spacing are considered equivalent.
The keys of the hash as returned by the "keys" and "each" functions
will be "Net::OSCAR::Screenname" objects, so you they will
automagically be compared without regards to case and whitespace.
findconn (FILENO)
Finds the connection that is using the specified file number, or
undef if the connection could not be found. Returns a
"Net::OSCAR::Connection" object.
selector_filenos
Returns a list whose first element is a vec of all filehandles that
we care about reading from and whose second element is a vec of all
filehandles that we care about writing to. See the
"process_connections" method for details.
icon_checksum (ICONDATA)
Returns a checksum of the buddy icon. Use this in conjunction with
the "icon_checksum" buddy info key to cache buddy icons.
get_app_data ([GROUP[, BUDDY]])
Gets application-specific data. Returns a hashref whose keys are
app-data IDs. IDs with high-order byte 0x0001 are reserved for
non-application-specific usage and must be registered with the
"libfaim-aim-protocol@lists.sourceforge.net" list. If you wish to
set application-specific data, you should reserve a high-order byte
for your application by emailing
"libfaim-aim-protocol@lists.sourceforge.net". This data is stored in
your server-side buddylist and so will be persistent, even across
machines.
If "GROUP" is present, a hashref for accessing data specific to that
group is returned.

buddy is returned.
Call "commit_buddylist" to have the new data saved on the OSCAR
server.

CALLBACKS
auth_challenge (OSCAR, CHALLENGE, HASHSTR)
New for Net::OSCAR 2.0: AOL Instant Messenger has changed their
encryption mechanisms; instead of using the password in the hash,
you may now use the MD5 hash of the password. This allows your
application to save the user's password in hashed form instead of
plaintext if you're saving passwords. You must pass an extra
parameter to "auth_response" indicating that you are using the new
encryption scheme. See below for an example.
OSCAR uses an MD5-based challenge/response system for authentication
so that the password is never sent in plaintext over the network.
When a user wishes to sign on, the OSCAR server sends an arbitrary
number as a challenge. The client must respond with the MD5 digest
of the concatenation of, in this order, the challenge, the password,
and an additional hashing string (currently always the string "AOL
Instant Messenger (SM)", but it is possible that this might change
in the future.)
If password is undefined in "signon", this callback will be
triggered when the server sends a challenge during the signon
process. The client must reply with the MD5 digest of CHALLENGE .
MD5(password) . HASHSTR. For instance, using the MD5::Digest module:
my($oscar, $challenge, $hashstr) = @_;
my $md5 = Digest::MD5->new;
$md5->add($challenge);
$md5->add(md5("password"));
$md5->add($hashstr);
$oscar->auth_response($md5->digest, 1);
Note that this functionality is only available for certain services.
It is available for AIM but not ICQ. Note also that the MD5 digest
must be in binary form, not the more common hex or base64 forms.
log (OSCAR, LEVEL, MESSAGE)
Use this callback if you don't want the log_print methods to just
print to STDERR. It is called when even "MESSAGE" of level "LEVEL"
is called. The levels are, in order of increasing importance:
OSCAR_DBG_NONE
Really only useful for setting in the "loglevel" method. No
information will be logged. The default loglevel.
OSCAR_DBG_PACKETS
Hex dumps of all incoming/outgoing packets.
OSCAR_DBG_DEBUG
Information useful for debugging "Net::OSCAR", and precious
little else.
OSCAR_DBG_SIGNON
Like "OSCAR_DBG_NOTICE", but only for the signon process; this
is where problems are most likely to occur, so we provide this
for the common case of people who only want a lot of information
during signon. This may be deprecated some-day and be replaced
by a more flexible facility/level system, ala syslog.
OSCAR_DBG_NOTICE
OSCAR_DBG_INFO
OSCAR_DBG_WARN
Note that these symbols are imported into your namespace if and only
if you use the ":loglevels" or ":all" tags when importing the module
(e.g. "use Net::OSCAR qw(:standard :loglevels)".)
Also note that this callback is only triggered for events whose
level is greater than or equal to the loglevel for the OSCAR
session. The "loglevel" method allows you to get or set the
loglevel.
ERROR HANDLING
CALLBACKS
error (OSCAR, CONNECTION, ERROR, DESCRIPTION, FATAL)
Called when any sort of error occurs (except see admin_error below
and buddylist_error in "BUDDIES AND BUDDYLISTS".)
"CONNECTION" is the particular connection which generated the error
- the "log_print" method of "Net::OSCAR::Connection" may be useful,
as may be getting "$connection->{description}". "DESCRIPTION" is a
nicely formatted description of the error. "ERROR" is an error
number.
If "FATAL" is non-zero, the error was fatal and the connection to
OSCAR has been closed.
rate_alert (OSCAR, LEVEL, CLEAR, WINDOW, WORRISOME)
This is called when you are sending commands to OSCAR too quickly.
LEVEL is one of RATE_CLEAR, RATE_ALERT, RATE_LIMIT, or
RATE_DISCONNECT from the "Net::OSCAR::Common" package (they are
imported into your namespace if you import "Net::OSCAR" with the
":standard" parameter.) RATE_CLEAR means that you're okay.
RATE_ALERT means you should slow down. RATE_LIMIT means that the
server is ignoring messages from you until you slow down.
RATE_DISCONNECT means you're about to be disconnected.
CLEAR and WINDOW tell you the maximum speed you can send in order to
maintain RATE_CLEAR standing. You must send no more than WINDOW
commands in CLEAR milliseconds. If you just want to keep it simple,
you can just not send any commands for CLEAR milliseconds and you'll
be fine.
WORRISOME is nonzero if "Net::OSCAR" thinks that the alert is
anything worth worrying about. Otherwise it is zero. This is very
rough, but it's a good way for the lazy to determine whether or not
to bother passing the alert on to their users.
snac_unknown (OSCAR, CONNECTION, SNAC, DATA)
Called when Net::OSCAR receives a message from the OSCAR server
which it doesn't known how to handle. The default handler for this
callback will print out the unknown SNAC.
"CONNECTION" is the "Net::OSCAR::Connection" object on which the
unknkown message was received. "SNAC" is a hashref with keys such as
"family", "subtype", "flags1", and "flags2".
CHAT CONNECTIONS
Aside from the methods listed here, there are a couple of methods of the
"Net::OSCAR::Connection::Chat" object that are important for
implementing chat functionality. "Net::OSCAR::Connection::Chat" is a
descendent of "Net::OSCAR::Connection".
invite (WHO, MESSAGE)
Invite somebody into the chatroom.
chat_send (MESSAGE[, NOREFLECT[, AWAY]])
Sends a message to the chatroom. If the NOREFLECT parameter is
present, you will not receive the message as an incoming message
from the chatroom. If AWAY is present, the message was generated as
an automatic reply, perhaps because you have an away message set.
part
Leave the chatroom.
url Returns the URL for the chatroom. Use this to associate a chat
invitation with the chat_joined that "Net::OSCAR" sends when you've
join the chatroom.
name
Returns the name of the chatroom.
exchange
Returns the exchange of the chatroom. This is normally 4 but can be
5 for certain chatrooms.
CONSTANTS
The following constants are defined when "Net::OSCAR" is imported with
the ":standard" tag. Unless indicated otherwise, the constants are
magical scalars - they return different values in string and numeric
contexts (for instance, an error message and an error number.)
ADMIN_TYPE_PASSWORD_CHANGE
ADMIN_TYPE_EMAIL_CHANGE
ADMIN_TYPE_SCREENNAME_FORMAT
ADMIN_TYPE_ACCOUNT_CONFIRM
ADMIN_ERROR_UNKNOWN
ADMIN_ERROR_BADPASS
ADMIN_ERROR_BADINPUT
ADMIN_ERROR_BADLENGTH
ADMIN_ERROR_TRYLATER
ADMIN_ERROR_REQPENDING
ADMIN_ERROR_CONNREF
VISMODE_PERMITALL
VISMODE_DENYALL
VISMODE_PERMITSOME
VISMODE_DENYSOME
VISMODE_PERMITBUDS
RATE_CLEAR
RATE_ALERT
RATE_LIMIT
RATE_DISCONNECT
GROUPPERM_OSCAR
GROUPPERM_AOL
TYPINGSTATUS_STARTED
TYPINGSTATUS_TYPING
TYPINGSTATUS_FINISHED
Net::AIM Compatibility
Here are the major differences between the "Net::OSCAR" interface and
the "Net::AIM" interface:
* No get/set method.
* No newconn/getconn method.
* No group parameter for add_permit or add_deny.
* Many differences in chat handling.
* No chat_whisper.
* No encode method - it isn't needed.
* No send_config method - it isn't needed.
* No send_buddies method - we don't keep a separate local buddylist.
* No normalize method - it isn't needed. Okay, there is a normalize
function in "Net::OSCAR::Utility", but I can't think of any reason
why it would need to be used outside of the module internals.
"Net::OSCAR" provides the same functionality through the
"Net::OSCAR::Screenname" class.
* Different callbacks with different parameters.
MISCELLANEOUS INFO
There are two programs included with the "Net::OSCAR" distribution.
"oscartest" is half a reference implementation of a "Net::OSCAR" client
and half a tool for testing this library. "snacsnatcher" is a tool
designed for analyzing the OSCAR protocol from libpcap-format packet
captures, but it isn't particularly well-maintained; the Ethereal
sniffer does a good job at this nowadays.
There is a class "Net::OSCAR::Screenname". OSCAR screennames are case
and whitespace insensitive, and if you do something like "$buddy = new
Net::OSCAR::Screenname "Matt Sachs"" instead of "$buddy = "Matt Sachs"",
this will be taken care of for you when you use the string comparison
operators (eq, ne, cmp, etc.)
"Net::OSCAR::Connection", the class used for connection objects, has
some methods that may or may not be useful to you.
get_filehandle
Returns the filehandle used for the connection. Note that this is a
method of "Net::OSCAR::Connection", not "Net::OSCAR".
process_one (CAN_READ, CAN_WRITE, HAS_ERROR)
Call this when a "Net::OSCAR::Connection" is ready for reading
and/or writing. You might call this yourself instead of using
"process_connections" when, for instance, using the
"connection_changed" callback in conjunction with "IO::Poll" instead
of "select". The "CAN_READ" and "CAN_WRITE" parameters should be
non-zero if the connection is ready for the respective operations to
be performed and zero otherwise. If and only if there was a socket
error with the connection, set "HAS_ERROR" to non-zero.
session
Returns the "Net::OSCAR" object associated with this
"Net::OSCAR::Connection".
USER INFORMATION
Methods which return information about a user, such as "buddy", will
return the information in the form of a hash. The keys of the hash are
the following -- note that any of these may be absent.
online
The user is signed on. If this key is not present, all of the other
keys may not be present.
screenname
The formatted version of the user's screenname. This includes all
spacing and capitalization. This is a "Net::OSCAR::Screenname"
object, so you don't have to worry about the fact that it's case and
whitespace insensitive when comparing it.
comment
A user-defined comment associated with the buddy. See
"set_buddy_comment". Note that this key will be present but
undefined if there is no comment.
alias
A user-defined alias for the buddy. See "set_buddy_alias". Note that
this key will be present but undefined if there is no alias.
extended_status
The user's extended status message, if one is set, will be in this
key. This requires that you set the "extended_status" capability
when creating the "Net::OSCAR" object.
trial
The user's account has trial status.
aol The user is accessing the AOL Instant Messenger service from America
OnLine.
free
Opposite of aol.
away
The user is away.
admin
The user is an administrator.
mobile
The user is using a mobile device.
typing_status
The user is known to support typing status notification. We only
find this out if they send us an IM.
capabilities
The user's capabilities. This is a reference to a hash whose keys
are the user's capabilities, and whose values are descriptions of
their respective capabilities.
icon
The user's buddy icon, if available.
icon_checksum
The checksum time of the user's buddy icon, if available. Use this,
in conjunction with the icon_checksum method, to cache buddy icons.
icon_timestamp
The modification timestamp of the user's buddy icon, if available.
icon_length
The length of the user's buddy icon, if available.
membersince
Time that the user's account was created, in the same format as the
"time" function.
onsince
Time that the user signed on to the service, in the same format as
the "time" function.
idle_since
Time, in seconds since Jan 1st 1970, since which the user has been
idle. This will only be present if the user is idle. To figure out
how long the user has been idle for, subtract this value from
"time()" .
evil
Evil (warning) level for the user.
Some keys; namely, "typing_status" and "icon_checksum", may be available
for people who the user has communicated with but who are not on the
user's buddylist.
ICQ-SPECIFIC INFORMATION
ICQ support isn't nearly as well-tested as AIM support, and ICQ-specific
features aren't being particularly actively developed. Patches for
ICQ-isms are welcome. The initial patch enabling us to sign on to ICQ
was provided by Sam Wong.
ICQ METHODS
get_icq_info (UIN)
Requests ICQ-specific information. See also the "buddy_icq_info"
callback.
ICQ CALLBACKS
buddy_icq_info (OSCAR, UIN, ICQ DATA)

HIGH-PERFORMANCE EVENT PROCESSING
A second way of doing event processing is designed to make it easy to
integrate "Net::OSCAR" into an existing "select"-based event loop,
especially one where you have many "Net::OSCAR" objects. Simply call the
"process_connections" method with references to the lists of readers,
writers, and errors given to you by "select". Connections that don't
belong to the object will be ignored, and connections that do belong to
the object will be removed from the "select" lists so that you can use
the lists for your own purposes. Here is an example that demonstrates
how to use this method with multiple "Net::OSCAR" objects:
my $ein = $rin | $win;
select($rin, $win, $ein, 0.01);
foreach my $oscar(@oscars) {
$oscar->process_connections(\$rin, \$win, \$ein);
}
# Now $rin, $win, and $ein only have the file descriptors not
# associated with any of the OSCAR objects in them - we can
# process our events.
The third way of doing connection processing uses the
"connection_changed" callback in conjunction with
"Net::OSCAR::Connection"'s "process_one" method. This method, in
conjunction with "IO::Poll", probably offers the highest performance in
situations where you have a long-lived application which creates and
destroys many "Net::OSCAR" sessions; that is, an application whose list
of file descriptors to monitor will likely be sparse. However, this
method is the most complicated. What you need to do is call
"IO::Poll::mask" inside of the "connection_changed" callback. That
part's simple. The tricky bit is figuring out which
"Net::OSCAR::Connection::process_one"'s to call and how to call them. My
recommendation for doing this is to use a hashmap whose keys are the
file descriptors of everything you're monitoring in the "IO::Poll" - the
FDs can be retrieved by doing "fileno($connection->get_filehandle)"
inside of the "connection_changed" - and then calling "@handles =
$poll->handles(POLLIN | POLLOUT | POLLERR | POLLHUP)" and walking
through the handles.
For optimum performance, use the "connection_changed" callback.
HISTORY
* 1.907, 2004-09-22
* Fixed assert failure on certain invalid input ("Buddy Trikill"
crash)
* 1.906, 2004-08-28
* Reorganized documentation
* 1.904, 2004-08-26
* Add $Net::OSCAR::XML::NO_XML_CACHE to prevent use of cached XML
parse tree, and skip tests if we can't load Test::More or
XML::Parser.
* 1.903, 2004-08-26
* Generate XML parse tree at module build time so that users don't
need to have XML::Parser and expat installed.
* 1.902, 2004-08-26
* Fixes to buddy icon upload and chat invitation decline
* Increase performance by doing lazy generation of certain
debugging info
* 1.901, 2004-08-24

buddylist modification errors and errors only seen when
modifying certain screennames; Roy C. rocks.
* We now require Perl 5.6.1.
* Workaround for bug in Perl pre-5.8.4 which manifested as a
"'basic OSCAR services' isn't numeric" warning followed by the
program freezing.
* "add_group" and "remove_group" methods added.
* Fixed a potential memory leak which could impact programs which
create many transient Net::OSCAR objects.
* 1.900, 2004-08-17

* blinternal now automagically enforces the proper structure (the
right things become Net::OSCAR::TLV tied hashes and the name and
data keys are automatically created) upon vivification. So, you
can do $bli->{0}->{1}->{2}->{data}->{0x3} = "foo" without
worrying if 0, 1, 2, or data have been tied. Should close bug
#47.
