[Pharo-project] ConnectionQueue broken?

by Schwab,Wilhelm K

Hello all, I did some long overdue networking, and tried ConnectionQueue in 1.3. My changed version, that appears to work, is below. The key to the potential fix is in adding the #yourself to this line: newConnection := socket waitForConnectionFor: 10; yourself. #waitForConnectionFor: returns true or signals an error, the true ends up replacing the socket with a boolean and badness results. Can anyone confirm this? Bill listenLoop "Private! This loop is run in a separate process. It will establish up to maxQueueLength connections on the given port." "Details: When out of sockets or queue is full, retry more frequently, since a socket may become available, space may open in the queue, or a previously queued connection may be aborted by the client, making it available for a fresh connection." "Note: If the machine is disconnected from the network while the server is running, the currently waiting socket will go from 'isWaitingForConnection' to 'unconnected', and attempts to create new sockets will fail. When this happens, delete the broken socket and keep trying to create a socket in case the network connection is re-established. Connecting and disconnecting was tested under PPP on Mac system 8.1. It is not if this will work on other platforms. Fixed to not accept the connection if the queue is full (gvc)." | newConnection | socket := Socket newTCP. "We'll accept four simultanous connections at the same time" socket listenOn: portNumber backlogSize: 4. "If the listener is not valid then the we cannot use the BSD style accept() mechanism." socket isValid ifFalse: [^self oldStyleListenLoop]. [true] whileTrue: [ socket isValid ifFalse: [ "socket has stopped listening for some reason" socket destroy. (Delay forMilliseconds: 10) wait. ^self listenLoop ]. [newConnection := socket waitForConnectionFor: 10; yourself. ] on: ConnectionTimedOut do: [:ex | newConnection := nil]. (newConnection notNil and: [newConnection isConnected]) ifTrue: [(accessSema critical: [connections size < maxQueueLength]) ifTrue: [newConnection := socket accept] ifFalse: [socket closeAndDestroy: 0]] ifFalse: [newConnection := nil]. (newConnection notNil and: [newConnection isConnected]) ifTrue: [ accessSema critical: [connections addLast: newConnection]. newConnection := nil. self changed]. self pruneStaleConnections].

Re: [Pharo-project] Try with Coral

Currently it has no impact, but I'm thinking Coral should integrate with the default code loader, in which case the extension would determine what happens with the script (i.e. *.st get parsed/loaded as a changeset, and *.{cst,coral} as a Coral script). -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

Philippe, Nick, Good enough: | theSession theRequestContext | theSession := self session. theRequestContext := self requestContext. self halt. That's effectively what I did by debugging past the sends. Thanks for the explanation! Bill

[Pharo-project] Trying to make KomHttpServer load in 1.4

by StÃ©phane Ducasse

Hi guys I saw that TranscriptStream is deprecated in 1.3 and I was looking at the logic of the Logger. I do not understand the use of isTranscriptStream especially since it is defined only on Stream ^ false and the EmergencyEvaluator which is particularly not respecting the stream protocol. Any suggestion? Stef

Re: [Pharo-project] Seaside image

by Nick Ager

Hi Bill, I can't do anything with request contexts in the image. > self session self requestContext etc won't work in the debugger as they are dynamic variables which use the exception mechanism to retrieve their value (search for references to WACurrentRequestContext) If you are in the debugger and you need the session or the request context you can either follow the stack trace until you find a variable holding the session or request context or just add the following code to the method you are debugging and resume the debugger: | theSession theRequestContext | . . . theSession := self session. theRequestContext := self requestContext. self halt. --- Hope this helps Nick > > > > ---------------- > > I don't understand what you have been doing wrong.
