----------------------------------------------------------------
AMARQUEE V1.43
(Released 4/27/97)
----------------------------------------------------------------
The Problem:
You have a great idea for a killer multi-player Internet game
or multi-user net app, but it's a total pain in the @)#$* to
write all the TCP connection and data synchronization code
you'll need to get it going. So you put your idea on the
back-burner and go play "MineSweeper" instead. And thus the
Amiga is deprived of a fun Internet app. D-oh! :(
The Solution: (well, okay, it's *a* solution, anyway)
Enter AMarquee. AMarquee is a system that handles all of
the icky information distribution details for you, allowing
you to concentrate on coding your application, rather than on
which data goes into which socket when. AMarquee consists of
a shared library and a TCP daemon, which work together to
get your data where it needs to be. Your program simply
calls amarquee.library functions to broadcast the data,
and waits on a provided MsgPort for data from other hosts.
Easy!
Features of amarquee.library (the shared library/API):
- Works with AmiTCP, Miami, or any other stack that is "AmiTCP compatible".
- Simple API that requires no knowledge of socket programming to use.
- Each AMarquee connection you make automatically and transparently
starts a seperate execution thread, so your app will never
be forced to wait while data is sent or received.
- An arbitrary number of connections may be active at once.
- Allows you to "subscribe" to data that interests you, so that
when the data is changed you will be automatically notified.
You never need to poll for anything!
- An easy mechanism for sending messages to one or many other
AMarquee clients that are logged into the same server.
- Standard Amiga wildcarding is supported in all applicable functions.
This allows you to easily and succinctly refer to one host or data
item, or many, as appropriate.
- Includes and several small example applications included.
- Operation is almost totally asynchronous for efficiency, but
several easy synchronization methods are available if you need them.
- Can also be used for direct client-to-client connections and
for making inetd-launched daemons.
Features of AMarqueed (the AmiTCP server):
- Works with AmiTCP, Miami, or any other stack that is "AmiTCP compatible".
- Fully multithreaded design, with one server process per connection.
- Re-entrant code, to minimize memory usage.
- Data is stored in a filesystem-like tree structure for simplicity,
flexibility and efficiency. Each client gets its own "home directory"
that it may write to or read from, and each client may also
read from the "home directories" of other clients.
- Efficient design minimizes CPU usage, net bandwidth, and execution time.
- Limits may be put on memory usage, number of connections, and/or
which clients or apps may connect. Only serve the hosts and apps
you want to serve!
- Supports data streaming to one or many clients at once.
- Data streaming and synchronization features let you be sure your
data was read by all interested hosts before you update it again.
- Automatically detects and eliminates "dead" connections (e.g.
if the client computer was shut down without quitting politely)
WHAT'S NEW IN VERSION 1.43:
1.43 : (Public Release 4/27/97) (amarquee.library v43)
* amarquee.library's QMessage freeing system had a design
flaw that was causing Enforcer hits and memory leaks. Fixed that,
and as a side effect, FreeQMessage is now much more efficient.
* Fixed a bug in QFreeSession that would cause it to deadlock
and hang the calling process when freeing QSessions that were
allocated with QNewHostSession.
* Fixed some typos, layout errors, and anachronisms in the .guide file.
Note that the server program, AMarqueed, has not changed in this
release. Only the client side, amarquee.library has been updated.
