I found the problem! Of course, it was my code
causing this. I was doing the equivalent of:
Object
new becomeForward: nil.
and this was nilling out the contents of that
KnownEnvironments dictionary. I tested with the above code, without my
code, and indeed it caused the problem. I am now avoiding both
SmallIntegers and nil when using #becomeForward:
Thanks for everyone's help in this
matter!

No?
Are there any senders of knownEnvironments and removeKey: et al? Do
you have changes to Dictionary grow code which causes a bug on rehash?

I'm not sure if this is the same context of the issue you had, but..
this seems like a good time to reflect on #becomeForward:. Until 5 or 6 years ago, we only had Object>>#becomeForward: (and not #becomeForward:copyHash:). #becomeForward: would mutate the identityHash of the argument to be that of the receiver, causing any identity-hashed collections it might be residing in to need to be rehashed. Unfortunately, mutating the identityHash of important objects such as an important Symbol in the SymbolTable (like, #at: !!); there was no time to rehash the SymbolTable or anything else before the system needed it, couldn't find it, and locked up. So we added Object >> #becomeForward:copyHash: so that false could be passed as the second argument, causing it not to mutate the identityHash of the target. - Chris On Wed, Jul 14, 2010 at 3:31 AM, Rob Withers <[hidden email]> wrote: > I found the problem! > > Of course, it was my code causing this.

I followed these instructions to the letter, and get the same result I
got a few weeks ago. I posted a question then, but no responses. May I try again? Everything seems to go just fine throughout these build instructions. For the final step, I put it in /usr/local/lib. make install prefix=/usr/local/lib/squeak and I made sure /usr/local/lib/squeak exists before doing the make install. The make install appears to work fine, and I am able to see squeak -version: $ squeak -version 3.9-7 #1 Wed Jul 14 12:07:56 CDT 2010 gcc 4.3.3 Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.20] Linux chrisT60p 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux plugin path: /opt/4dst/thirdparty/squeak/lib/squeak/3.9-7/ [default: /opt/4dst/thirdparty/squeak/lib/squeak/3.9-7/] However, when I try to launch an image: squeak my.image The image does not launch and I get the following: could not find display driver vm-display-X11; either: - check that /usr/local/lib/squeak/3.9-7//vm-display-X11.so exists, or - use the '-plugins <path>' option to tell me where it is, or - remove DISPLAY from your environment. notice the double-slash in reference to the plugins location. Perhaps that's the problem, but what's the correct solution? Any advice is greatly appreciated.. - Chris On Tue, Jul 13, 2010 at 4:04 PM, Levente Uzonyi <[hidden email]> wrote: > On Tue, 13 Jul 2010, Rob Withers wrote: > >> Thanks Levente.

Hi Frank,
what errors do you get? I use 4.1.x on linux and 3.4.4 under cygwin on win32 and have used gcc 4.2 on Mac. The basic requirement is support for sse2 instructions.
BTW, this really should be on vm-dev...

Hi Eliot, if you replied to my original post under a different
subject, I must have missed it: http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-June/151522.html I do not have adequate C or C++ experience to even run the debugger. I really just want to _get_ a Cog VM so I can be more productive in getting my work done so I can then work on things like learning new langauges and tools... :) I had hoped, given that the problem seems to be exposed (the double-slash) that the cause and solution would be obvious to someone..

One thing I noted you said: "#becomeForward: would mutate the identityHash of the argument to be that of the receiver, causing any identity-hashed collections it might be residing in to need to be rehashed." The first time I read it as if you were causing the rehashing to occur, but on second reading you only said that Sets and Dictionaries are in need to be rehashed. I.e. it is up to the application programmer to cause the rehash. Mine is a slightly different situation, concerned with hashed locations where the receiver WAS, which is now the target with a different hash. Here is the appropriate code snippet in my system: rehashables := self collectRehashableCollections. context isSmallInteger ifTrue: [self becomeForward: context copyHash: false] ifFalse: [self becomeForward: context]. rehashables do: [:each | each rehash]. Therefore, I need to rehash collections holding the receiver. collectRehashableCollections | level1 level2 sets level3 dictionaries | level1 := Utilities pointersTo: self except: #(Array with: self). level2 := level1 inject: OrderedCollection new into: [:coll :elem | coll addAll: (Utilities pointersTo: elem except: #(Array with: self with: elem)). coll]. sets := level2 select: [:elem | elem isKindOf: Set]. level3 := level2 inject: OrderedCollection new into: [:coll :elem | coll addAll: (Utilities pointersTo: elem except: #(Array with: self with: elem)). coll]. dictionaries := level3 select: [:elem | elem isKindOf: Dictionary]. ^ sets, dictionaries Rob > - Chris > > On Wed, Jul 14, 2010 at 3:31 AM, Rob Withers <[hidden email]> wrote: >> I found the problem! >> >> Of course, it was my code causing this.

Hi Chris,
>>> could not find display driver vm-display-X11; either: - check >>> that /usr/local/lib/squeak/3.9-7//vm-display-X11.so exists, or this is just a quick fly-by suggestion. I don't think the "//" matters since I can do either of these... ls -l /usr/local/lib/squeak/3.10-3/vm-display-X11 ls -l /usr/local/lib/squeak/3.10-3//vm-display-X11 So maybe you need (on one line)... ln -s /usr/local/lib/squeak/3.9-7/vm-display-X11 /usr/local/lib/squeak/3.9-7/vm-display-X11.so Notice I'm on a different version so I can't rule out a version specific build problem.

In reply to this post by Eliot Miranda-2
Changing subject for sanity. Is there a place to file bugs against the open source version of Cog? (*nudge*) It might improve signal:noise in any event. I realize that OSCog is the community's responsibility! But if we're going to be responsible about shepherding it, we may as well add a category to Mantis (or something.) What do folks think about that? FWIW, I had the same symptom running Ubuntu 10.4; Eliot was kind enough to suggest some things I might explore with the debugger, but I haven't had time to drill down into it (just took a new job, ramping up on a pile of software and relational tomfoolery.) It seems like it's a distro-issue. I'm curious, and I understand that it might not be apropos to disclose, but on the off chance it is, what GNU/Linux distro has Cog seen the most testing on? This thread seems to have wandered a bit, but I'll read the whole thing and then forward his suggestions if they still seem promising and haven't been reproduced here.

I'm curious, and I understand that it might not be apropos to disclose, but on the off chance it is, what GNU/Linux distro has Cog seen the most testing on? That's really strange, because I succesfully built Cog on Ubuntu 10.4 and it works fine. Today I even managed to compile the plugin for FFI and Alien (thought none of them works :)) and the UUIDPlugin. I also fixed the cryptography plugins, those work well (at least the tests pass). Back to your problem: after compiling I only have vm-display-X11, but no vm-display-X11.so. Are you sure you're not mixing the files/VMMaker of the CogVM and the SqueakVM?

Eliot, if I came across as having any expectations of you
specifically, then I do apologize. My intent was to only to solicit help from any willing party with my immediate problem.

In reply to this post by Levente Uzonyi-2
Levente,
I suspected the same. I was running an older Ubuntu release. I thought maybe I had cruft left over from my old VM, (or from a couple of Cog builds that failed because I was missing dependencies,) and maybe that was causing my problem. So I paved the disk, installed 10.4, and built Cog w/o ever installing another VM. Same symptom, with the weird double slash in the error message.

In reply to this post by Derek O'Connell-2
Hmm. That's an interesting try. I tried renaming vm-display-X11 to vm-display-X11.so, and that didn't help; which confounds me. Is there a reason that using a symlink would have a different effect from my rename try?
