That one on the left is the one that trailer kind answers #VarLengthSourcePointer the right is the correct one. You can also notice that the one of the left in addition to not having the last bytecode (self return), it has only 2 bytes for the trailer. Anyway, regardless of how such CM could have been generated, I CANNOT find who is pointing to them. They appear only in PharoDev and I cannot find any pattern between them :( :( On 9 May 2011 11:22, Mariano Martinez Peck <marianopeck(a)gmail.com> wrote: > > > > > > On Mon, May 9, 2011 at 10:53 AM, Mariano Martinez Peck > > <marianopeck(a)gmail.com> wrote: > >> > >> > >> On Mon, May 9, 2011 at 10:27 AM, Nicolas Cellier > >> <nicolas.cellier.aka.nice(a)gmail.com> wrote: > >>> > >>> Hi Mariano, > >>> you should try these two things before repeating yourself: > >>> > >>> (CompiledMethod allInstances select: [:each | each trailer kind = > >>> #VarLengthSourcePointer] ) first trailer kind. > >>> > >>> | temp | > >>> temp := (CompiledMethod allInstances select: [:each | each trailer > >>> kind = #VarLengthSourcePointer] ) first. > >>> temp == (temp methodClass >> temp selector) > >>> > >> > >> Thanks Nicolas.

To solves those issues, we have a Metacello configuration. Gofer has nothing to do with a secured environment or not: all you have to do is to load the package ConfigurationOfSqueakDBX. No matter how: you can use the following Gofer script: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSqueakDBX'; load. Or, open a Monticello Browser, -> add repository -> www.squeaksource.com/MetacelloRepository -> select ConfiguratonOfSqueakDBX -> load. Once you have download ConfigurationOfSqueakDBX all you have to do is: (ConfigurationOfSqueakDBX project version: #stable) load. I *really* recommend you to read the Metacello chapter of Pharo By Example, since all this is explained there: https://gforge.inria.fr/frs/download.php/28462/Metacello.pdf Cheers Mariano > Please advice me if am wrong and suggest me the correct method for it.

Re: [Pharo-project] Issue in loading SqueakDBX Patch

HiI have noticed that when I load the patch SqueakDBXSmalltalkDialectMarianoMartinezPeck.5, the class SqueakDBXSmalltalkDialect does not contain any methods in the system window.

For the Future, I would like to establish a new rule that a failing project is removed (with all its dependencies) from Hudson after 2 weeks of faling builds. A Project with a failing build over a long has proven to the world that nobody is interested in it. In addition, automatic builds don't make sense if they are broken all the time. -> Pharo Clients now are build for 1.3 in addition to 1.2 https://pharo-ic.lille.inria.fr/hudson/view/Pharo-Clients/ NOTE: Seaside is broken. This is due to MetaCello config that needs to be done for 1.3. It would be nice if someone would take the lead in fixing this.

Re: [Pharo-project] Adding "Extended Search" to OB context menu

by Lukas Renggli

Sure, that can be done. The point is that the RB code menu is fully implemented in OB now. Previously OB just used the menu provided by Pharo, what caused all kinds of problems. "Method source with it" was never an operation backed by OB.
