Yes, I am sure. With 1.3 the startup script could be: ZnServer startDefaultOn: 8080 and the server would keep on running. With 1.4 the following script: NonInteractiveTranscript stout install. (ZnServer defaultOn: 8080) logToTranscript; start.

Re: [Pharo-project] [Pharo-users] Pharo Morphic View Application Framework

by S Krish

Sure I will review this pdf.. and come back on this..how well should integrate the specs part.. The framework though is based on the spec and extensibly on direct composition and does a little more towards building a scalable/ flexible framework that incorporates in one simpler hierarchy all that goes into a standard large application creation.. How is the Presenty work supposed to work along with this..?

Are you sure that you do not have an error because it would kill it. I do not see what we change to get the behavior you mentioned.

Look here: https://github.com/timn/roslua > Basically I think you are right that embedded systems are comparable. But there are still two different sizes of computers addressed. The plug computer mentioned is a full capable server computer just without a display. You can use VNC and such easily there because they have enough power and memory (of course a remote ide is way cooler and more powerful). For this size I find it more important to have FFI and JIT for ARM in place to utilize the machine. There is still a kind of machines that have real limited resources and for this it would be necessary to have a tiny core and a remote IDE connection to actively modify the system. If this kind of computers is targetted then it will be a big challenge for the pharo core. If the core is not capable of operating with less resources then I think it'll be hard to achieve much on this platform. Norbert

Re: [Pharo-project] End of startup script behavior

by Schwab,Wilhelm K

Sven, Reminds me of one of early Dolphin hacks. OA being who they are, eventually fixed the snag. The problem was that event loop needed to be running for some late startup tasks to run properly. In this case, the image would do nothing vs. quit, but I suspect it's the same lesion under a different name. My fix was to queue a deferred action and then fork a thread to wait until after OA's startup, and then did the offending work. It worked, and they added more or less the same thing to Dolphin. Interestingly, I never had to remove my hack<g>, Please note (nobody wants to hear this) that Dolphin has thread synchronization objects, weak collections, and other nice things that make us look bad by comparison, even ignoring the calendar differences. Good luck!

It used to be that the image kept on running unless you asked it to quit explicitly, now it seems that the image automatically quits unless you keep it busy. Can someone confirm this ? Was this intentional ? What would be the recommended way to keep the image open ? Somehow something like [ (Delay forDuration: 1 hour) wait ] repeat. seems so silly, but it works. Thx, Sven

Re: [Pharo-project] CogVM driver vs executable

by Schwab,Wilhelm K

Sven, I'm not sure what to tell you. The "can't infer" message you are experiencing ***might*** be the one time the vm is actually telling what's wrong. If so, it's PROGRESS. Doesn't feel like that in your shoes, I know.... The bane of my existence is a silent failure (I dread those two word in that sequence...) of the vm to look in the right place. What did Nick suggest to me? strace, I think (it's in the archives). You might run under it to see if you can gain some insight; the tool in question does not pt DON'T LET THIS HAPPEN TO YOU<g>: the tool in question[*] logs its output to sterr(?), not stdout as one might expect. If you try it, use the -o option (I think) to direct to a file, then cat and grep are your friends. I remember "streaming" this into the archives, but I can't see them to check the facts. I solved my problem by noting where the vm was actually looking and making sym links to trick it (should not have to...) into working (very good). Let's all send kind thoughts to Sig - maybe he'll pull the search policy into the image, where it belongs. We will still want vm level logging (syslog etc.) in case the image can't run. SECURITY: Ubuntu gets it right (took me a while to realize same) by "forcing" us to use dlconfig to map names to libraries. I don't really understand it all, but I might be able to fake some useful answers if that is confusing. You might need to use dlconfig to "fix" Ubuntu, and then links to fool the vm into looking where it should. HTH, Bill [*] short term memory disorder<g>, which is precisely why we want informative errors reaching the Smalltalk code (and?)/OR(ideal) being logged (OutputDebugString or syslog) where one can readily find it. Errors rare enough that we get time to forget between them. Pharo needs to help us a bit more - afteall, it works for us, right? ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] on behalf of Sven Van Caekenberghe [sven(a)beta9.be] Sent: Tuesday, January 31, 2012 3:30 AM To: Pharo-project(a)lists.gforge.inria.fr Development Subject: [Pharo-project] CogVM driver vs executable In response to my posting http://lists.gforge.inria.fr/pipermail/pharo-project/2012-January/058790.ht… I got feedback from people trying to use SSL with Eliot's CogVM http://www.mirandabanda.org/files/Cog/VM/VM.r2522/coglinux.tgz instead of the Pharo one that I normally use http://gforge.inria.fr/frs/download.php/29042/CogVM-Unix-13307.zip They reported that it did not work for them. So I tried this myself on my Ubuntu 11.10 (GNU/Linux 3.0.0-14-virtual i686) server and yes it fails with 'can't infer base LD_LIBRARY_PATH. Aborting.' which was discussed in this list before. I am not qualified to really understand those discussions. But when I used the executable 'inside' coglinux/lib/squeak/4.0-2522/squeak everything worked as expected. So the question is what does the driver (I don't know if that is the right word) coglinux/squeak or coglinux/bin/squeak do ? Since the pharo variant seems to operate fine without it, do we need the driver ? Sven
