browser update problem
by Joshua Gargus 27 Apr '99

27 Apr '99

Hi there, When I grab a browser from the right-hand global flap, it doesn't update itself when I add a new class, method, etc. If I get a new browser from the flap, it shows the changes. If I open a browser with 'open...' from the root menu, it works fine. I tried reinstating the flaps, and when that failed, I tried to figure out the problem from the 'Utilities reinstateGlobalFlaps' method; still no luck. Has anyone encountered this? I'm using image 2.4b with a few changes of my own that are almost too trivial to mention. Any suggestions? Thanks, Josh

Re: Steps to Modularity - Incremental Snapshots
by Dan Ingalls 27 Apr '99

Folks - A week or so ago, I sent out a message describing a technique for extracting segments from the Squeak image. What I want to know is, Does anyone know of such a technique having being used previously? I figure it must be known, but I have certainly never heard of it. Please reply directly to me. To recap, here's how it works: 1. Mark the root (or roots) of the subtree desired. 2. Do a GC mark pass. SInce this stops at any marked objects, the subtree will be unmarked, "in the shadow" of its roots. 3. Copy the roots and the unmarked subtree into a byteArray (the image segment) Relocate internal pointers as you go Copy external pointers into a table of outpointers. Reinstalling a segment is incredibly simple -- all you do is remap any pointers in one pass and throw away the byteArray header! Thanks - Dan PS... Ted and I have just completed an implementation and it is great. (It will be out in updates and release 2.4 within a week). It can trace and copy a 520kb tree of over 15000 objects in about 390ms. Used for deepCopy, it is about 20 times faster than what we do currently. Used to swap segments in and out, it finally offers a realistic vehicle for breaking down Squeak's monolithic images. It's even faster than you would guess from the above. There is a fixed overhead for the full GC mark and unmark. This is 350ms on my machine (could surely be improved). It can then copy out the 520kb segment or reinstall it in about 40ms either way.

Re: Change in mailing list "From:" field?

Sigh... Looks like the problem is probably at my end since it sounds like no one else is seeing it. My current suspicion is that it's the gateway that translates Internet email into Lotus Notes mail. (I looked at the hidden fields in the message that I receive in Notes, and there's nothing resembling the original sender's address.) Sorry to bother everyone.

Change in mailing list "From:" field?
by wirth＠almaden.ibm.com 27 Apr '99

27 Apr '99

In the past, the "Reply to:" field in Squeak mailing list messages listed the mailing list address, and the "From:" field listed the person who submitted the message. This had the desirable effect that a simple reply (in most email apps) would go to the full list. It seems like this changed recently (on 4/21) so that the mailing list address is listed in both fields. Was this a conscious change? It has the bad effect that, unless the originator includes a full signature block, the reader can't identify who sent the message or reply just to that individual.

RE: Question

Hi Jen. I don't believe that the system browser dialogs have "stay open" menus, but I know that Bob Arning's browser does. His browser is still under development (i.e. it changes more frequently than the system browser), but it is cool. You might want to check it out.

Re: Win95 sound problem

Somewhere along the line I was told that your sound card has to be SoundBlaster Pro compatiable.

If I turn the volume way up, I can hear an increase in static volume when I ask Squeak to play a sound, but no sound itself. No Bach, for example.

Re: Minimum file set required for headless app?

The VM would start fine but the app >would not be running. Why does Squeak require the source code to run? SImply because the file initialization code tries to open them and then consults the user if they cannot be found. For the time being, I would simply edit the code for FileDirectory>>openSources:andChanges:forImage: so that it doesn't try to inform the user. From then on, the system should be able to deal with missing sources and changes. >Are the sound and 3d libraries required with a headless VM? They should not be, unless called for, but I don't know how unix/linux manage .so files. Hope this helps. - Dan

Question
by Smilie 26 Apr '99

26 Apr '99

Inside Morphic I know that you can get the desktop menu to stay open or you can use the flaps. What I want to know is there any way to keep window specific menus up? I.e. I right-click in a Workspace is there anyway to keep that menu up? When you have to do the same thing 24 times over, it gets old real fast, and i'm not real big into short-cut-keys. -------------------- Jen a.k.a. Smilie :-P smilie(a)cc.gatech.edu

RE: Win32 Sources for Squeak 2.4 VM?
by Raab, Andreas 25 Apr '99

25 Apr '99

Peter, The sources on the server are not up to date for 2.4. They should compile with a little tweaking but I'm right now working on a couple of VM changes (e.g., UDP sockets, Win CE changes ...) and I'll put out an updated VM sometime soon. Once these changes are finished, I'm planning to put the latest sources out there (this will hopefully be in <= 2 weeks).
