ListModel Menu
by Jonathan Khalil April 4, 2017

April 4, 2017

Hello, I am testing the MenuModel and ListModel widgets. I wanted to create a popup menu and then set it with the ListModel >> menu: method. It runs right but once the listmodel open, when i right click on one item to see the pop-up menu it gives me the error as in the "#error.png" picture. Here is my example test (based on not significant data): [ menu := MenuModel new. menu addGroup: [ :group | group addItem: [ :item | item name: 'item1'; icon: (self iconNamed: #nautilus); action: [ anyAction1 ]]]; addGroup: [ :group | group addItem: [ :item | item name: 'item2'; icon: (self iconNamed: #smallSaveAs); action: [ anyAction2 ]]]; addGroup: [ :group | group addItem: [ :item | item name: 'item3'; icon: (self iconNamed: #smallAuthoringTools); action: [ anyAction4 ]]]. ll := LinkedList new. ll add: 'value1'; add: 'value2'; add: 'value3'; add: 'value4'; add: 'value5'; yourself. lm := ListModel new. lm items: ll; title: 'ListModel Menu Test'. *lm menu:menu.* lm openWithSpec. ] I get that the #cull:cull: message is not understood by my instance of MenuModel but i simply call the #menu: method defined in ListModel. Any ideas on the problem ?

unable to start linked vm file (linux)
by John Brant April 3, 2017

April 3, 2017

I'm unable to start a linked vm file (ln). I have several vm's, and I link to the one that I want to use. However, it appears that this no longer works. With the April 3rd threaded vm on http://files.pharo.org/vm/pharo-spur64/linux/, I get the following error when it tries to start: ldd: ./lib/pharo/5.0-201704030814/pharo: No such file or directory Error. Could not determine platform's libc path for VM. Try forcing $PLATFORMLIBDIR in ./pharo, based on LIBC_SO. Please report what works to pharo [vm-dev] mail list. LIBC_SO= DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.2 LTS" NAME="Ubuntu" VERSION="16.04.2 LTS (Xenial Xerus)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 16.04.2 LTS" VERSION_ID="16.04" VERSION_CODENAME=xenial UBUNTU_CODENAME=xenial UNAME=Linux p5810.refactoryworkers.com 4.4.0-71-generic #92-Ubuntu SMP Fri Mar 24 12:59:01 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux System seems to be 64 bit. You may need to (re)install the 32-bit libraries. This worked for the March 10th vm. John Brant

Esteban's ChangeLog week of 27 March 2017
by estebanlm＠gmail.com April 3, 2017

April 3, 2017

Hello! This is my weekly ChangeLog, from 27 March 2017 to 2 April 2017. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=27/3/2017&to=2/4/2017 ChangeLog ========= 31 March 2017: -------------- * Yesterday I spent most of the day verifying why the pharo site was going down time to time... as a result, we found a problem in Voyage that may cause a deadlock under heavy load. Finally, with the help of Guille we help a possible cause in the way the +VOLazyProxy+ is implemented. This is +#doesNotUnderstand:+ current implementation: ---- VOLazyProxy>>doesNotUnderstand: aMessage | realObject | realObject := self obtainRealObject. realObject ifNil: [ (repository descriptionBuilder for: objectClass) isAllowMissingContent ifTrue: [ realObject := VOMissingObject class: objectClass id: objectId ] ifFalse: [ VOError signal: ('Lazy reference not found {1}: {2}' format: {objectClass name. objectId}) ] ]. VOLazyProxy mutex critical: [ self == realObject ifFalse: [ self becomeForwardKeepingHash: realObject ] ]. ^realObject perform: aMessage selector withArguments: aMessage arguments. ---- It is designed to prevent double attempt to become when trying to access same proxy at concurrent moments (in webapps is very frequent). We discovered this implementation has some problems: * When doing the comparisson of of +self+ with +realObject+ self can already be in the stack, and then it can fail. * apparently the error handler handles the occurrence of +Semaphore+ in a stack in weird ways (to ensure is debuggable) :) So, now I'm testing (and proposing to Voyage) this implementation: ---- VOLazyProxy>>#doesNotUnderstand: aMessage | realObject thisObject error | realObject := self obtainRealObject. realObject ifNil: [ (repository descriptionBuilder for: objectClass) isAllowMissingContent ifTrue: [ realObject := VOMissingObject class: objectClass id: objectId ] ifFalse: [ VOError signal: ('Lazy reference not found {1}: {2}' format: {objectClass name. objectId}) ] ]. error := nil. thisObject := self. VOLazyProxy mutex critical: [ thisObject == realObject ifFalse: [ [ self becomeForwardKeepingHash: realObject ] on: Error do: [ :e | error := e ] ] ]. error ifNotNil: [ VOLazyProxyBecomeError new error: error; signal ]. ^realObject perform: aMessage selector withArguments: aMessage arguments. ---- If this works, I will submit an update to [Voyage](http://github.com/pharo-nosql/voyage) immediately :) 29 March 2017: -------------- * I validated some changes to Athens and copyBits primitive to fix the crashing problem. Seems to be working so I will integrate it... thanks Eliot! * Still with [Iceberg](https://github.com/npasserini/iceberg), I took care of some bug... but most important than that, I added an option to create repositories from Iceberg. This is very simple: you click in the "New repository" button :) This way you do not need a remote repository to start working, and you can keep your versions in your local environent if you want. *WARNNING*: When doing your first push, it has to be a clean push (fast-forward), I have had problems trying the otherwise (which triggered a merge that Iceberg still does not knows how to handle). 27 March 2017: -------------- * I just spent sometime fixing stuff on [Iceberg](https://github.com/npasserini/iceberg). * I fixed [issue 313](https://github.com/npasserini/iceberg/issues/313) (now user gets a dialog to set user properties when needed). * Now commit dialog remembers last choice of "push" automatically while commiting. cheers!
