Sorry about the broken patches. I blame Lotus Notes and the cretins who forced it upon us. Please find attached the two diffs. The next diff will include the change to replace "from foo import *" with "from foo import required-stuff". Please let me know if this comes through okay. I don't trust Lotus Notes.

Well, struct seems almost like an overkill, but could probably replace most usage of these routines. If I should need a good reason for keeping them, it would be my uncertainity of its (structs) endianism/portability since the codes need to be. It just looks like a module only used in interfacing. This is an only excuse since I didn't know of struct. :) Thanks for the tip // phed

Further progress... I have changed the Drop routine for the Romero figure. It first tests if the location hasIntelligence() before broadcastToPair() the fact it made a noise when dropped. Is testing the location for hasIntelligence() the standard way of finding out if the location is a guest/player? I would think that the broadcast routine could be coded as one routine with the following parameters: (self, subject, to_target, to_subject, to_other) self = reference for the thing where the broadcast originates from subject = person acting on the thing to_target = message for thing to_subject = message for subject to_other = message for others I admit I have not sat down and thought about all the different scenarios. I'll get to that soon. Hopefully, there will only need to be a few broadcast routines (preferably one) which will be suitable for all situations. Glyph, I will provide a diff as soon as we can work out what to do with the container problem I mentioned in this thread yesterday.

I know where the problem is, but I don't know the solution. I know *a* solution, but not if it is the right one :) If I 'pull string' when the figure is in the room, I get the messages once. If I take the figure and 'pull string', I get the messages twice. This is because broadcastToPair() sends the message to all containers associated with the figure's current location. If I leave the figure where it is, the containers are 'Room'. But when I take the figure the containers are 'Guest' and 'Room'. My proposed solution is to not include the location's containers in the container list. I am not sure of all of the effects of doing this. I know when I do this that I get the messages once whether I have taken the figure or not. I don't know how to test this with multiple players :( on Win98. And I don't know the code well enough to understand the logic behind it. I also think the set of broadcast routines should be standardised, especially at this early stage. That way, there will be some standards for TRDemo and Inheritance as well as any future games. Some broadcast routines just call others. I do have plans to port the more common IF examples to TR (Golden Skull, Alice In Wonderland) and perhaps the Greedy Gargoyle from PUB :) when I run out of things I wish to do to TR. The 'drop' routine for the figure also needs some work. If I drop it when I don't have it, I get the message (the self squeaks). If I take it and drop it, I don't get the message. All that is needed is a test to see if the current location is a guest and broadcast the message then. I don't know why there is a call to InappropriateVerb after the message. Hopefully I will get some more time later to sort this out. Cheers, ChrisH -- This transmission is for the intended addressee only and is confidential information.

[Twisted-Python] tcp.Port.stopListening =)
by Benjamin Bruheim 03 Sep '01

03 Sep '01

Hm, well, I just ask out of fear of a "security-hole". dtpPort is now a listening Port. Right now I have self.pi.dtpPort.loseConnection() in DTP.connectionLost, so that it won't take any connection as soon as the transfer is done. But won't dtpPort accept connections as long as the transfer is going on? If I put the loseConnection in connectionMade I get that twisted.internet.tcp.Port has no fileno plus an failed attempt of closing the socket (since there's no Port-instance anymore). Should the API behave this way? // phed - master of the obvious

[Twisted-Python] Another tcp.Client question
by Itamar 03 Sep '01

03 Sep '01

Another question - shouldn't we return when getting a EWOULDBLOK or friends, since we haven't yet connected? ======================== class Client(Connection): #... def doConnect(self): """I connect the socket. Then, call the protocol's makeConnection, and start waiting for data. """ try: self.socket.connect(self.addr) except socket.error, se: if se.args[0] in (EWOULDBLOCK, EALREADY, EINPROGRESS): pass ########### XXX shouldn't this be "return"? XXX else: self.protocol.connectionFailed() return CONNECTION_LOST # If I have reached this point without raising or returning, # that means that the socket is connected.

[Twisted-Python] What the hell?

02 Sep '01

From tcp.py: ============ class Client(Connection): """A client for TCP (and similiar) sockets. """ def __init__(self, host, port, protocol): """Initialize the client, setting up its socket, and request to connect. """ if host == 'unix': # "port" in this case is really a filename ... ============ That is sooo wrong. What if my computer is named 'unix'? Why does the TCP code deal with files?
