Squeak Http GET broken?
by Nevin Pratt 28 Dec '05

28 Dec '05

This should be simple, but it's got me stumped. First, plug the following URL into any browser (Mozilla, IE, Thunderbird, Safari, or whatever, all one line in the URL panel): http://testing.shippingapis.com/ShippingAPITest.dll?API=Verify&XML=<AddressValidateRequest ><Address ID="0"><Address1></Address1><Address2>6406 Ivy Lane</Address2><City>Greenbelt</City><State>MD</State><Zip5></Zip5><Zip4></Zip4></Address></AddressValidateRequest> You should get back the following response from the shippingapis.com machine: <Error> <Number>80040b19</Number> <Description>XML Syntax Error: Error getting USERID attribute.</Description> <Source>UspsCom::DoAuth</Source> </Error> And, this is how it should be. And, I would like to duplicate this behavior via Squeak code. So, I try, for example, the following: HTTPClient httpGetDocument: 'http://testing.shippingapis.com/ShippingAPITest.dll?API=Verify&XML=<AddressValidateRequest><Address ID="0"><Address1></Address1><Address2>6406 Ivy Lane</Address2><City>Greenbelt</City><State>MD</State><Zip5></Zip5><Zip4></Zip4></Address></AddressValidateRequest>' I would think that the above would be the programmatic equivalent of the URL I typed into Thunderbird (I also tried it with Safari, and both Safari and Thunderbird gave me the same results). But when I do it programmatically in Squeak, I get back this response: HTTP/1.1 400 Bad Request Server: Microsoft-IIS/5.0 Date: Tue, 27 Dec 2005 03:46:44 GMT Content-Type: text/html Content-Length: 87<html><head><title>Error</title></head><body>The parameter is incorrect. </body></html> I was expecting the "XML Syntax Error" response that Thunderbird (as well as Safari) gave me instead of this nonsense. But I instead got back something totally different. Why? OK, let's try Scamper. So, I plug in the URL I mentioned, and I get the following response in Scamper: error occured retrieving http://testing.shippingapis.com/ShippingAPITest.dll?API=Verify&XML=<AddressValidateRequest ><Address ID="0"><Address1></Address1><Address2>6406 Ivy Lane</Address2><City>Greenbelt</City><State>MD</State><Zip5></Zip5><Zip4></Zip4></Address></AddressValidateRequest>: HTTP/1.1 400 Bad Request Server: Microsoft-IIS/5.0 Date: Tue, 27 Dec 2005 03:50:47 GMT Content-Type: text/html Content-Length: 87<html><head><title>Error</title></head><body>The parameter is incorrect. </body></html> So, Scamper is also giving me something different from the "XML Syntax Error" response I was expecting. Why? I've tried every combination of GET and/or POST I could think of. I just don't understand why Squeak is giving me a different result than Thunderbird gives me. Anybody know? In case you are curious, if I include my login ID as an XML arg of the URL, the shippingapis.com machine will validate my address(es) that I pass to it. I just didn't think it would be a good idea to post my login ID. Besides, it is unnecessary to do so, because if I solve the above problem, I will solve my *real* problem, and will be able to programmatically validate any US-based address. Anybody know why Squeak is giving me different results than the web browsers do? Nevin

[ANN] BB-Tree package
by Matej Košík 27 Dec '05

27 Dec '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I have a first version Binary B-Tree implementation (in our countries traditionally denoted as 2-3-Trees). Because I had quite foggy ideas of how these kind of things are working (though it is so easy to describe it informally), I have decided to complete my own implementation. It is a delicate problem and I am quite unsure that the way how I implemented it is the best (the clearest, the simplest etc) way. I have looked into Wirth's Algorithms and Data Structures, but it did not helped me much. I will try to ask people around me if they tried it and if so, how did they managed it. Apart from operations for addition and removal of elements, the rest code should be readable. I almost like it. Anyone willing to play with this new collection can install it this way: - - install the `COND' package (unfortunatelly, this is necessary) - - install the `BBTree' package I have found out that sorted-collection are more effective than BB-trees when there are fewer elements in the collection (1000 or so). But as number of elements in the collection increases (to 100000 or so), it is evident that BB-tree rulez. There is an example method BBTree example1 which - - creates new BB-tree - - adds 100000 intergers (could be any other objects which could be totally ordered) in some (random) order to the BB-tree - - removes those object (at different, also random) order from the BB-tree It is possible to observe (there is a progress-bar) that addition and removal operations virtually do not depend on the number of elements in the collection (or if, then very "little", because height of the tree grows very "slowly") On the other hand, there is an example BBTree example2 which does the same as `example1' but not with BB-tree but ordinary SortedCollection. It is observable that the addition/removal operations depend on the number of elements in the collection. It is also visible that removal is much more expensive than addition. As I mentioned, addition and removal operations are bad. It is straightforward realization of non-trivial operation. I am not sure if I could rewrite it in a simpler way soon. But if I find out how, I will do it. But there might be also other things I have forgotten to do or could be done better. So comments are welcome.

delay (Transcript vs Morphic)
by Mark Polishook 27 Dec '05

27 Dec '05

this works tr := Transcript open. 3 timesRepeat: [ tr show: 'hello'. tr cr. (Delay forSeconds: 1) wait. ] this doesn't work. y := 100. offset := 20. 3 timesRepeat: [ t := TextMorph new openInWorld. t contents: 'hi'. t position: 100@y. y := y + offset. (Delay forSeconds: 1) wait. ] desired behavior is 1 sec. between each TextMorph posting. actual behavior is a 3 second or so delay, then simultaneous posting of 3 TextMorphs what's the problem/misunderstanding? how should a 1 sec. delay between each TextMorph drawing be written? (tia)

[Swiki] Help requested
by Peace Jerome 27 Dec '05

27 Dec '05

The squeak swiki at gatech states on its improvement page: >Since no one is directly responsible for checking this page and following up, if you have a serious suggestion for a major change to the Swiki, probably your best bet is to post a suggestion to the *Squeak Mailing List*. And enforces it by asking for a password. I think a reference to that exists somewhere on the list but I couldn't think of it when asked and what I wanted to do was request an improvement. So here goes... Request: On the changes page. Give an intermediate option for the number of changes displayed. The current changes page shows just a weeks worth of changes. The option to show full changes gives you four years worth maybe more . Rendering all that data takes a fairly boring long time. Even pressing the stop button once you are bored waiting is too late. It still takes a long time from that point to finish. The point is I may only want to see a month or a season or a years worth of the change file. Something intermediate and/or heirarchical will make the page more useful. Thanks for your help. Yours in service, -- Jerome Peace P.S. Is there a swiki catagory on mantis or anyone following mantis for swiki bugs? __________________________________ Yahoo! for Good - Make a difference this year. http://brand.yahoo.com/cybergivingweek2005/

Squeak 3.8-6665 with Mac OS X VM 3.8.9beta7 very slow
by Yar Hwee Boon 27 Dec '05

27 Dec '05

I've just started a fresh Squeak 3.8-6665 running with Mac OS X VM 3.8.9beta7. I've loaded some web development stuff including Seaside, Magma. Morphic response seems horribly slow compared to 3.7. CPU util reads 90-100% when dragging a workspace for eg. and it takes a few seconds to actually see it move. Does anyone know what could be wrong or what diagnostics I can do? I'm on a 1.2 GHz iBook with enough RAM, if it matters at all. Thanks! -- Hwee Boon http://motionobj.com/blog/ MotionObj (65) 6764-9774

Brent>Remeber that Duration and DateAndTime are part of the Smalltalk ANSI standard. Brent>They should be avalable in VW. [ref: http://article.gmane.org/gmane.comp.lang.smalltalk.squeak.seaside/4095] Well, yes and no. No, because Cincom provides neither DateAndTime nor Duration for VW. Yes, because Chronos provides both (http://www.chronos-st.org). --Alan -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
