OSCog updated
Locked
 
|
Hi All,
I've updated http://ftp.squeak.org/Cog with new source, OpenSourceCog-oscog.16.tar.gz/VMMaker-oscog.16.mcz that fixes the three issues people have found:
Nicholas' crash on loading SUnit.dtl.?? which was a very nasty bug in the GC'ing of some trace logs the VM maintains. It was down to a difference between Smalltalk's \\ and C's %, specifically that the latter can answer something of different sign to the modulus.
The failure of GeneratorTest, superficially due to cannotReturn: crashes, but fundamentally to do with inter-page returns to frames within the page not preserving the frames above, which can be in use due to co-routining (swapSender: usage). I hope this will fix Seaside on Cog. Please let me know.
Crashes due to temps occurring in very simple blocks (that Cog compiles frameless) e.g. [ | b | 5 ] value. HTH Eliot

Hi,
I'm sending this response to squeak-dev as well, as that is the more appropriate place ... Cog works well with trunk images; you need to have the latest updates in there, though. If I understand your message correctly, you seem to be unable to update to the latest trunk, right? Have you set the update site to http://source.squeak.org/trunk in the preferences (under Monticello)? Once all the updates are in, Cog starts up my trunk image, and I'm enjoying the speedup. :-) Pre-built releases take time to prepare, and please bear in mind that Cog was released just some few days ago. Also, Cog does have its glitches (I experience some difficulties with bytecode simulation, but also with stepping in the debugger - report upcoming) and is probably not 100 % stable for all purposes that the non-Cog VMs were well suited for. To summarise, while Cog is the "latest and greatest", as you put it, it should be considered beta. The stable Squeak release is 4.1 plus the latest VM, and in my actually not so humble opinion it is completely sufficient to provide pre-built releases for *that*. Perhaps I misunderstood you here and there: apologies for that, then.

Michael,
the specific problem (which i thought i spelled out fairly well): i cannot find how to make cog update from TRUNK: the BUTTONS do not work in the preferences... which means that when i do, or try to reset the update site, the buttons just stop working - nothing happens when i click on them - they do not even PRETEND to be "clicked on... :)": " Have you set the update site to http://source.squeak.org/trunk in the preferences(under Monticello)?"... YES - and the buttons do nothing after i do that. i click on any button, or anything whatsoever, and the preference goes back to what it was before... i cannot "save" the preference to update via trunk (under Monticello)... that is THE issue :) and that was the ONLY point i was trying to make :) Thanks for replying with in a helpful way :) ken Hi, I'm sending this response to squeak-dev as well, as that is the more appropriate place ...

Hi Eliot,
> (swapSender: usage). I hope this will fix Seaside on Cog. Please let me > know. Thank you for the update, unfortunately the update does not seem to fix the problem with Seaside. I've ripped out the failing functionality and the associated tests. You should be able to load Seaside-Pharo-Continuation and Seaside-Tests-Pharo-Continuation into any recent Pharo or Squeak image to reproduce the problem. On traditional VMs all 16 tests pass.

yes, save button do not work in 4.1. One must use Alt+s to save changed field. |

> ...i cannot find how to make cog update from TRUNK: the BUTTONS do not work in the preferences... There is no need to press Alt-S in a changed field, the Enter-Key just works fine. You don't need to click on any save button to make the changes in the preferences work. The save/load buttons just save/load the current state of the Preferences to memory/file. There seems to be still a bug, so that saving to memory won't work. http://www.youtube.com/watch?v=DyzZxCBO-yc Alex |

Hi Eliot,
Thank you for the quick fix. I can confirm that all 1600 Seaside 3.0 tests run green now. However I stil get random crashes when using Seaside through the webbrowser. Sometimes it survives 30 requests, sometimes it crashes right after the first request. In the console I get: nanosleep: Invalid argument Exited with exit code: 1 How can I further debug this? I cannot reproduce it with the tests. It only happens (randomly) when using Seaside through the webbrowser.
