modified method temp references in closures: possible bug?
by Max Leske Aug. 3, 2013

Aug. 3, 2013

I just came across this (possible) bug and I'm able to reproduce it in Pharo 2.0 and 3.0 with the latest PharoVM (found in a 1.3 with NBCog): expected (by my feeble mind): 1 2 actual: 2 2 | methodScope | collection := OrderedCollection new. 1 to: 2 do: [ :index | methodScope := index. dict add: [ methodScope ] ]. collection do: [ :block | Transcript show: block value; cr ] I'm aware that using method temps in this way is not good programming style (usually) but I still think this behavior is curious if not at least very likely to cause a lot of weird errors. Should I open a bug report? Cheers, Max

flash: does not work in Pharo 3.0
by StÃ©phane Ducasse Aug. 2, 2013

Aug. 2, 2013

Display flash: (0@0 corner: 200@200) does not work on Pharo 30 while it was working on 2.0. It looks that this is VM related because on the linux of laurent it is working. I'm too tired to get how to extract the VM versionâ¦. I tried --version and others but it did not work. pharo -version bin unknown option: -version Usage: [<option>...] [<imageName> [<argument>...]] [<option>...] -- [<argument>...] Common <option>s: -help print this help message, then exit -memory <size>[mk] use fixed heap size (added to image size) -headless run in headless (no window) mode (default: false) Notes: <imageName> defaults to `Squeak.image'. If `-memory' is not specified then the heap will grow dynamically. <argument>s are ignored, but are processed by the Squeak image. The first <argument> normally names a Squeak `script' to execute. Precede <arguments> by `--' to use default image. bin pharo -version 'NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 NBCogit NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 git://gitorious.org/cogvm/blessed.git Commit: 412abef33cbed05cf1d75329e451d71c0c6aa5a7 Date: 2013-03-13 17:48:50 +0100 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14535 ' Stef too tired and exhausted to think

Morph inspect weird behavior
by Erwan Douaille Aug. 2, 2013

Aug. 2, 2013

Hi, I found something else weird, When i inspect a Morph the bounds are resized. Do it : a := Morph newBounds: (Rectangle origin: (0@0) corner: (300@300) ). a color: Color red. a openInWorld Now click on the morph, open halo, inspect it and the bounds are resized. Is that normal ? (I guess not) Thanks :) -- Best regards, Douaille Erwan <douaille.erwan(a)gmail.com>

New Cog VMs available
by Eliot Miranda Aug. 2, 2013

Aug. 2, 2013

...at http://www.mirandabanda.org/files/Cog/VM/VM.r2761/. CogVM binaries as per VMMaker.oscog-eem.317/r2761 Fix bug in transferTo:(from:) when doing a code compaction when ensuring there is a machine code method when switching to a process whose context has a machine code pc. Limit the ammount of space the Cogit will stack allocate when compiling. This limits the maximum number of bytecodes in a method that the Cogit will compile. Currently set at 1.5Mb of stack space from empirical tests of alloca on Mac OS X 10.6, linux 2.6 & Windows XP. Fix become for cog methods that are not paired with their bytecoded methods (e.g. Newspeak accessors). Linux: There are two variants of the Linux VMs; those ending in "ht" have a heartbeat thread, while those that don't, use an interval timer for the heartbeat (the Windows and Mac VMs have a threaded heartbeat). The threaded heartbeat is better (for example, signals from the interval timer interfere with system calls, etc), but to use it one must have a kernel later than 2.6.12 and configure linux to allow the VM to use multiple thread priorities. To do so, create a file called VM.conf where VM is the name of the vm executable ("squeak" for the Squeak vm, "nsvm" for the Newspeak vm) in /etc/security/limits.d/ with contents: * hard rtprio 2 * soft rtprio 2 e.g. sudo cat >/etc/security/limits.d/squeak.conf <<END * hard rtprio 2 * soft rtprio 2 sudo cp /etc/security/limits.d/squeak.conf /etc/security/limits.d/nsvm.conf END Then log out and log back in for the limits to take effect. -- best, Eliot

Windows problem with FilePlugin ?
by Benjamin Aug. 1, 2013

Aug. 1, 2013

On my image, when opened in Windows, opening the File Browser leads to a red square of death :s And using the UIManager to popup the file picker leads to an infinite loop of halt :s Do you experienced that too ? Can people using windows try the following line: (FileSystem disk root) directories This gives me C:, D:, F:, G: where actually only C: and G: are presentâ¦ It seems to come from DiskStore>>#basicEntry:path:nodesDo: [â¦] [ entry isNil ] whileFalse: [ entry at: 1 put: (Primitives decode: entry first). aBlock value: entry. index := index + 1. entry := Primitives lookupEntryIn: encodedPathString index: index ]. So I would say it comes from the primitives. Ben

New PharoVM built
by Esteban Lorenzano Aug. 1, 2013

Aug. 1, 2013

Hi, I builded new versions of the vm, integrating latest changes from Eliot. This integration should fix some issues, between them the annoying "SmallInteger" problem. You can find it here: wget -O- get.pharo.org/20+vmLatest or directly here: http://files.pharo.org/vm/pharo/ (choose the one that fits the best for you, always the "latest") can you download and check? thanks, Esteban
