Fogbugz 13260 reappears?
by Alistair Grant June 26, 2016

June 26, 2016

Hi All, I'm currently regularly hitting an issue with the debugger where inspecting a temporary variable shows the string "error obtaining field value" rather than the actual value. Selecting the temporary variable and attempting to inspect it in the code pane results in: True(Object)>>doesNotUnderstand: #indexInTempVectorFromIR: OCVectorTempVariable>>searchFromContext:scope: DebuggerMethodMapOpal>>tempNamed:in: DebuggerMethodMapOpal>>namedTempAt:in: Context>>namedTempAt: GlorpSession>>DoItIn: OpalCompiler>>evaluate RubSmalltalkEditor>>evaluate:andDo: RubSmalltalkEditor>>highlightEvaluateAndDo: [ textMorph textArea editor highlightEvaluateAndDo: ann action. textMorph shoutStyler style: textMorph text ] in [ textMorph textArea handleEdit: [ textMorph textArea editor highlightEvaluateAndDo: ann action. textMorph shoutStyler style: textMorph text ] ] in GLMMorphicPharoMethodRenderer(GLMMorphicPharoCodeRenderer)>>actOnHighlightAndEvaluate: in Block: [ textMorph textArea editor highlightEvaluateAndDo...etc...

Is this a known problem, should I open a new issue, or...? Thanks! Alistair

Image freezes on Linux if it was previously saved on Windows
by Maximiliano Tabacman June 25, 2016

June 25, 2016

Hi. I am not sure if this issue is known, or what files to provide to help fix it.In the latest image (60112, but my guess is that this will happen with all Pharo 6 images) if I download a clean latest image, start Pharo on Windows, save the image, then copy it to a Linux environment, and try to start it, the image freezes even before displaying the workspace (I get an unresponsive black and white box in Linux, only killable through xkill command).I am sure this did not happen back with Pharo 5.If I output "./pharo Image.image > log.txt" I end up with a huge file since there seems to be an infinite loop while trying to determine the FileStore to use. The first lines of this output file, before going into the loop, are: out of memory /home/theUser/Downloads/Pharo6/pharopharo VM version: 5.0 #1 Tue Jun 21 12:37:33 CEST 2016 gcc 4.6.3 [Production Spur ITHB VM]Built from: CoInterpreter VMMaker.oscog-HolgerHansPeterFreyther.1880 uuid: 16138eb3-2390-40f5-a6c8-15f0494936f8 Jun 21 2016With: StackToRegisterMappingCogit VMMaker.oscog-HolgerHansPeterFreyther.1880 uuid: 16138eb3-2390-40f5-a6c8-15f0494936f8 Jun 21 2016Revision: https://github.com/pharo-project/pharo-vm.git Commit: 9638b0190a9fc01479bfb752becd96edfd253c8c Date: 2016-06-21 12:29:26 +0200 By: GitHub <noreply(a)github.com> Jenkins build #594Build host: Linux pharo-linux 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 UTC 2012 i686 i686 i386 GNU/Linuxplugin path: /home/theUser/Downloads/Pharo6/ [default: /home/theUser/Downloads/Pharo6/] C stack backtrace & registers:*./pharo[0x80c133c]./pharo(error+0x17)[0x80c1547]./pharo[0x809a26c]./pharo[0x809a301]./pharo[0x809a53d]./pharo[0x809bf13]./pharo[0x80a6b61]./pharo[0x80ae4ca]./pharo[0x80ae6ba]./pharo[0x80af07f]./pharo[0x80afcf4]./pharo(ceSendsupertonumArgs+0x1d8)[0x80b0098][0x990008d][0x990de03][0x99090af][0x9900b70][0x990dda3][0x990de03][0x99090af][0x9900b40][0xffe95808] Smalltalk stack dump:0xffe9e9f8 I MacStore class(Class)>subclassesDo: 0xa3393f0: a(n) MacStore class0xffe9ea14 M MacStore class(Behavior)>allSubclassesDo: 0xa3393f0: a(n) MacStore class0xffe9ea34 M [] in UnixStore class(Behavior)>allSubclassesDo: 0xa339380: a(n) UnixStore class0xffe9ea58 M Array(SequenceableCollection)>do: 0x9ded798: a(n) Array0xffe9ea7c I UnixStore class(Class)>subclassesDo: 0xa339380: a(n) UnixStore class0xffe9ea98 M UnixStore class(Behavior)>allSubclassesDo: 0xa339380: a(n) UnixStore class0xffe9eab8 M [] in DiskStore class(Behavior)>allSubclassesDo: 0xa339310: a(n) DiskStore class0xffe9eadc M Array(SequenceableCollection)>do: 0x9ded710: a(n) Array0xffe9d7c8 I DiskStore class(Class)>subclassesDo: 0xa339310: a(n) DiskStore class0xffe9d7e4 M DiskStore class(Behavior)>allSubclassesDo: 0xa339310: a(n) DiskStore class0xffe9d800 M DiskStore class>activeClass 0xa339310: a(n) DiskStore class0xffe9d81c M DiskStore class>currentFileSystem 0xa339310: a(n) DiskStore class0xffe9d834 M DiskStore class>current 0xa339310: a(n) DiskStore class0xffe9d84c M DiskStore class>delimiter 0xa339310: a(n) DiskStore class0xffe9d864 M DiskStore(FileSystemStore)>delimiter 0x9deb478: a(n) DiskStore0xffe9d884 M DiskStore(FileSystemStore)>pathFromString: 0x9deb478: a(n) DiskStore0xffe9d8a4 M DiskStore>defaultWorkingDirectory 0x9deb478: a(n) DiskStore0xffe9d8bc M FileSystem>initializeWithStore: 0x9deb488: a(n) FileSystem0xffe9d8dc M FileSystem class>store: 0xa2e2978: a(n) FileSystem class0xffe9d8f8 M DiskStore class>currentFileSystem 0xa339310: a(n) DiskStore class ... and so on...from #currentFileSystem to #store: and again...

Better color contrast for class extensions in dark theme
by Offray Vladimir Luna CÃ¡rdenas June 25, 2016

June 25, 2016

Hi :), I'm enjoying the Pharo Dark Theme a lot (in fact my tweet on a 10 minutes hack about it[1] have more impact that the tweets with month and a half work behind for Panama Papers[2]... that's life :-P), but I still have some suggestions on color contrast, particularly when you're doing class extensions and the light gray over blue makes the reading really difficult (see screenshot at bottom). [1] https://twitter.com/offrayLC/status/738828257680850944 [2] https://twitter.com/offrayLC/status/729069808684285953 Hope this helps to improve this theme. Cheers, Offray

[FFI] Passing a null in argument
by Merwan Ouddane June 24, 2016

June 24, 2016

Hi, I wanted to call a function using null as argument but did not managed to do so. I tried to use an integer, but the FFI forbids it. I tried to use FFIExternalObject null, but the FFI vould not coerce the arguments. To make it work I had to duplicate the method and set 0 instead of an argument. void foo (0); Is it possible to do it the first way ? Regards, Merwan

SQLite on multiple images
by Hilaire June 23, 2016

June 23, 2016

Hi, I have a question regarding the use of the same SQLite DB from several Pharo images (all running in the same host, but likely on different cores). Is it safe in this scenario? I mean does lock on write operation correctly work? Thanks Hilaire -- Dr. Geo http://drgeo.eu
