by tomkoenig＠mindspring.com 02 Jun '04

02 Jun '04

with a 3.7b and 5923 updates, plus MC, BFAV-1570fbs.mcs, I go to install the three cs associated with this fix. install first one successfully, go to install second one and get the following walkback Error: PatchArchiveAttachments are not indexable I have tried various install orders, but it appears that once i install any of these 3 cs's, I can not install any other. I have also experienced this problem with earlier versions eg with update 5905.

Connectors 1.9 fail to install gracefully in post 5880 images
by German Morales 02 Jun '04

02 Jun '04

Hi all, Connectors 1.9, the version available in SqueakMap, won't install (gracefully) in images with the update 5880. The problem is that the postscript tries to do this: ConnectorsInfo instVarNamed: 'default' put: nil. ConnectorsInfo is a subclass of PackageInfo, and the class variable "default" is gone since 5880. Manually editing the postscript commenting that line seems to work. Or at least installs without complaining. Enjoy!

socket input instead of mouse
by Randy Heiland 02 Jun '04

02 Jun '04

Greetings, Apologies up-front from a total newbie developer. (We're experienced software developers, just not in Squeak/Smalltalk - and yes, we're aware of the good tutorial links at squeak.org) We were wondering what it would take to run Squeak on a particular custom display/interaction device here in our labs (running Linux). I'll be vague for brevity. Basically, the question becomes, can we replace the function of the mouse in Squeak with a stream of (x,y), pen up/down commands via a socket? We would welcome any pointers at kick-starting our efforts. Our goal is to have something by Squeakfest in Aug :) Also, I didn't see a search engine on the Sqeak-dev archives, but if one's available, could someone point that out as well? Thanks!

[BUG][FIX]ExceptionTest>simpleOuterTest
by Tim Rowledge 02 Jun '04

02 Jun '04

After much staring at code I hope never to see again I believe that the actual test for simpleTestOuter is broken rather than the exception code. Assuming anybody else is willing and able to delve into that pit of nightmares they might like to review this change. tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Useful random insult:- "Body by Fisher -- brains by Mattel."

I also went to the list website yesterday, but forgot my password, so I asked the website to email me the password. I didn't receive that email until today. I think there is a mail server somewhere that was broken over the weekend, and after the holiday weekend ended, the admin fixed it.
