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.

copyAllTo:
by Hilaire July 29, 2016

July 29, 2016

copyAllTo: does not do what its comment says: '/tmp/toto/titi' asFileReference ensureCreateDirectory. '/tmp/dest' asFileReference ensureCreateDirectory. '/tmp/toto' asFileReference copyAllTo: '/tmp/dest' asFileReference 'toto' directory is not copied contrary to what wrote the method comment. What is wrong, the comment or the method? Hilaire copyAllTo: aResolvable "Performs a deep copy of the receiver, to a location specified by the argument. If the receiver is a file, the file will be copied; if a directory, the directory and its contents will be copied recursively. The argument must be a reference that doesn't exist; it will be created by the copy." -- Dr. Geo http://drgeo.eu

Error: cannot create OS pipe
by J.F. Rick July 28, 2016

July 28, 2016

I've been using CommandShell for some operations on OSX with Pharo5. After doing a number of "PipeableOSProcess command:" calls (~150), I get an error inside ExternalPipe:makePipe. For my purposes, I can get around this by restarting Pharo and limiting the number of operations each session. But, it is an indication that some resource is not getting freed when the PipeableOSProcess is deleted (garbage collected). I just thought I'd mention the bug. Cheers, Jeff

Pharo 5.0 Tiny Feature Request
by Sean P. DeNigris July 28, 2016

July 28, 2016

I know our policy is to only backport severe bug fixes, but I have one method I'd like added to 5.0 which would make my life a lot easier. Since NBMacShell has been removed, there doesn't seem to be a built-in way to send simple shell commands, which has broken all my project/image load scripts. I propose the following addition which will restore that basic functionality: LibC class>>system: command ^ self ffiCall: #(#int #system #(#char #* #command)) module: self It doesn't change any existing behavior, so seems relatively risk-free. What do you think? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Pharo-5-0-Tiny-Feature-Request-tp4901682.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
