[Q] Running headless (squeak, not me)
by Brian Brown 10 Apr '03

10 Apr '03

I put an image on an FreeBSD server and if run the image under X, it serves out just fine... if I give it the -headless parameter, it doesn't. Is there something else I have to do? (I read the stuff on the Swiki about running headless and VM command line options) Brian

Hmm, Dave Winer (the inventor of XML-RPC) helped creating SOAP and, as far as I know, created XML-RPC the same time as a lightweight alternative. The consequence is that XML-RPC knows nothing about namespaces, complex data, objects, state or other transport layers that http.

I gathered you changed the name of the process message in ComancheNG to #processHttpRequest: rather than #process and that you were basically tracking Avi's WAKom>>process: with your WAKomNG>>processHttpRequest:, so all I did was move the method body from Avi's WAKom>>process: to your WAKomNG>>processHttpRequest: . Is there a better way of keeping these in sync? If not, so be it; I am *delighted* to have you refactoring and improving Comanche and to have Avi and Julian refactoring and improving Seaside. The occasional resync is a small price to pay. -- Frank

[ANN] ComancheNG 1.0.1
by Stephen Pair 10 Apr '03

10 Apr '03

ComancheNG 1.0.1 enables the use of ComancheHttpService in a pluggable manner (using MessageSend or BlockContext). This makes it possible to use without subclassing. Here are a couple of examples: (ComancheHttpService on: 8080 named: 'Example Http Service') onRequestDispatch: #processRequest: to: SomeGlobal; start (ComancheHttpService on: 8080 named: 'Example Http Service') onRequestDo: [ :httpRequest | SomeGlobal processRequest: httpRequest ]; start http://map2.squeakfoundation.org/sm/package/1ad6581f-6890-4c21-ae97-6b06bfb… http://people.advantive.com/~spair/squeak/ComancheNG-1.0.1.sar - Stephen

what happened to WAComponent>>parent?
by Derek Brans 10 Apr '03

10 Apr '03

what happened to WAComponent>>parent? Is there any mechanism for going up the gui hierarchy? Do I understand that calling "self call:" now replaces the calling component, as opposed to some Container higher up the hierarchy? It was nice when there was a certain component which would "catch" the call because often there is a well-specified real-estate that you want to be swapping out. thanks, Derek Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com

More 2.3 questions related to modules (sections)
by Derek Brans 09 Apr '03

09 Apr '03

Is there support in 2.3 for cookie-based session id's ? I'm trying to implement modules (sections) again in 2.3. The approach I used in 2.2 was that when it came time to lookup the continuation for an action key, if the key was absent the session would say "self start" in order to recreate the root controller. I've overriden session>>performRequest to do that. I've inserted a self halt in this same method. However, if I delete the action key from the url in my browser and fetch that url, the page shows itself as expired (performRequest was never called). I'm baffled how that happened. Any ideas? here is my code for performRequest: performRequest: aRequest lastAccess _ Time totalSeconds. path _ aRequest path. self halt. <<< is never called when action key is absent. aRequest actionKey = '' ifTrue: [self start]. (continuations at: aRequest actionKey ifAbsent: [[:r | self unknownRequest: r]]) value: aRequest Thanks, Derek Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com

I haven't really seen that used before, so I thought it was related to that, but the problem only rears it's ugly head when you are greater that 2 levels deep in rendering components using the WAHtmlRenderer>>imageWithForm: > Also, Brian, on a side note, you may not be aware, but you should > avoid starting new threads by replying to old ones.

Widget implementation question
by Derek Brans 08 Apr '03

08 Apr '03

I used to have a date selector widget in 2.2 that was a subclass of ValueView. The complicated thing about a date widget that's in a form and represents a member on an object is that there are 3 UI components and you need to take the result of all 3 (day, month, year) to come up with a date object that get's sent to the setter for a member. In my ValueView subclass I had rendering code like this: renderOn: html renderDayChooserThatSetsMyDayState renderMonthChooserThatSetsMyMonthState renderYearChooserThatSetsMyYearState html renderHiddenInputWithValue: 'ignore' callback: [:ignore | self turnMyStateIntoADateObjectAndPassItToMyModel] I think this problem can be generalized but I haven't come up with a succinct way of doing that. Anyone handled the same problem before? Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com

Seaside 2.3 questions
by Derek Brans 08 Apr '03

08 Apr '03

I've been inspecting 2.3 code. I love the way it's organized in layers. WARegistry seems to have just done away with the session cache. Can we still have application-specific session expiration rules? Which example seaside applications are the best examples of 2.3 - style programming? What's the best way to do the following in 2.3 1. Insert code to determine the entry point based on the path (used to be "unhandled request") 2. pass on POST values from a non-seaside form to an entrypoint What is a WATask? It seems to be a controllor that encapsulates a method "go" that calls other components to render themselves. In its rendering it does something I don't understand and uses WASimulatedRequestNotification. I forget if there was a change in heart as to where stuff like database connection should reside for the components to access. Was that still in the Session object?
