Hi, I am trying to open an image I saved a few days ago and I am getting this message (the whole log is attached): stack page bytes 4096 available headroom 2788 minimum unused headroom 3020 (Segmentation fault) Anyone experiencing something similar?

Limbo/PharoInProgress repositories
by Serge Stinckwich July 29, 2016

July 29, 2016

Dear all, on SquareBracketAssociates github org, I see a Limbo repo : https://github.com/SquareBracketAssociates/PharoLimbo and a PharoInProgress repo: https://github.com/SquareBracketAssociates/PharoInProgress Basically there are collections of chapters that are not part of any books until now. And there is also a repo called: PharoReadyForReviews https://github.com/SquareBracketAssociates/PharoReadyForReviews for chapters ready for reviews but with some chapters more than 2 years old. Does it make sense to merge all these repos in one ? Having too much repos, we forget about the others ... BTW, I add a draft of a chapter regarding Continuations (in French) I wrote several years ago : https://github.com/SquareBracketAssociates/PharoLimbo/blob/master/Continuat… Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Option for as-in-moose debugger layout
by Yuriy Tymchuk July 29, 2016

July 29, 2016

Hi, is it possible to have some setting to switch the debugger into the layout that is used in Moose? I.e. have the stack vertically on the left. Because come on, look at this image: only 3 lines of variables? And you see all that empty space on the right both in source code and variables pane? Cheers. Uko

segfault fresh Pharo5.0 download w/pharo VM version: 5.0 #1 Wed May 4 11:54:28 CEST 2016 gcc 4.6.3 [Production Spur ITHB VM]

I was doing a fresh build from a bash script and from the looks of the last couple of lines it looks like that there are new changes in this image from yesterday: "Postscript: Leave the line above, and replace the rest of this comment by a useful one. Executable statements should follow this comment, and should be separated by periods, with no exclamation points (!!). Be sure to put any further comments in double-quotes, like this one." |repository| repository := MCHttpRepository location: 'http://smalltalkhub.com/mc/Pharo/Pharo50/main' user: '' password: ''.

If you look at the bottom of the stack you will notice that WorldState>doOneCycle is being called and that's suspiciously similar to the issue I reported yesterday[1] ... but a segfault this time instead of an MNU.. I will go through the drill of trying to see which part of the script is hitting this problem and provide more info ... It would be nice to get a clean build sooner rather than later :) Dale [1] https://pharo.fogbugz.com/f/cases/18706#BugEvent.170987

newly introduced problem in Pharo5.0 running headless vm (Ubuntu 14.04)
by Dale Henrichs July 29, 2016

July 29, 2016

This sequence of commands was working yesterday and is broken today: ./pharo Pharo.image save xxx; ./pharo xxx.image --quit --save ./boom.st The contents of boom.st is the following: Metacello new baseline: 'Metacello'; repository: 'github://dalehenrich/metacello-work:master/repository'; onConflict: [:ex | ex allow]; load: #( 'batch' ). I've attached to PharoDebug.log ... The Pharo.image is freshly downloaded along with the vm. Needless to say, the expression above works when run with a GUI. Oddly enough the receiver of #finish looks to be a temp named 'canvas' in the middle of the WorkState>>displayWorld:submorphs: method ... two lines earlier the' canvas' temp had to have a valid value, so this has the look of a zombie process of some sort that is being brought to life at the wrong moment ... stdout for the run follows.
