[Pharo-project] FileTree sources
by Camillo Bruni Aug. 3, 2012

Aug. 3, 2012

I am trying to fix FileTree for 2.0 without FileDirectory. Can anyone give the mcz versions (they usually get cached) to fill the gap between the gemstone and the github repos? Cause currently I cannot merge, and I realized that only after applying all the changes... best cami

[Pharo-project] R.I.P. FileDirectory
by Esteban Lorenzano Aug. 2, 2012

Aug. 2, 2012

Hi, In update 20240 we finally completed the unload of FileDirectory. From now, just FileSystem is available to manipulate files... AFAIK, this is the biggest (and almost the only) "incompatible" change from 1.4 to 2.0, so I recommend framework developers to start your migration right now, so they are usable by 2.0. Don't wait until it is to late! :) (Also, that can be useful to detect FileSystem bugs now, and not next year) Cheers, Esteban

[Pharo-project] A VM-dev blog. (Was: Re: Going meta (VM development))
by Igor Stasenko Aug. 2, 2012

Aug. 2, 2012

So, i registered a blog on wordpress and sent invitation to join to following people: Esteban, Dave, Eliot, Guillermo, Camillo, Dimitry, Sean. The blog address is dailyVMotion.wordpress.com The idea behind this blog is to brag about what you do, what you did or what you plan to do.. It don't have to be too technical or too precise (as documentation does), but just hold enough information to navigate in the VM sea and stay tuned. So, people can put notes, read others notes, comment, and then (the most important aspect) return back to things after a while once they find time to deal with it, instead of digging mail archives.. Not saying, that visitors can be more aware of what happens around VM. Note, this is NOT my private blog or something. All participants will have admin rights and all can post whatever they want there, of course if it related to VM. So, if you like the idea, then join :) P.S. I am not sure that i invited all today's Cog VM developers. So, if i miss someone, please forgive me, (it was not intentional) and let me know, so i can fix this :) -- Best regards, Igor Stasenko.

[Pharo-project] Possible FFI issue
by Diego Lont Aug. 2, 2012

Aug. 2, 2012

Hi all, I am working with Friedrich on the ODBC issue, that the doubles aren't read correctly, and this is the point where I got by following the code: in the class: 'ByteArray' the function "doubleAt:" is implemented as a FFI-Kernel primitive. <primitive:'primitiveFFIDoubleAt' module:'<SqeakFFIPrims>'> In a version based on the seaside one click (Pharo v 1.3) this results in the correct double, but in the Pharo one click v1.4, this results in a double that is way too small. Writing a C program that makes the "same" api calls in ODBC also results in the correct values, although it gives an funny value for sqlTypLen (53). But we are kinda stuck here. Can someone give us the code of FFI, so we can continue debugging here, and possibly making a fix here? Also: does someone know what has changed between v1.3 and v1.4 in FFI, because both are loaded with the same Configuration. Thanks in advance for all the help, Diego Lont

[Pharo-project] We cannot remove package [was] Re: How to correctly remove a package for everywhere?
by Mariano Martinez Peck Aug. 2, 2012

Aug. 2, 2012

So....again this problem. Please guys, this is a stop-the-world problem. We simply cannot remove packages. In http://code.google.com/p/pharo/issues/detail?id=6493 I removed lots of packages. The packages does not seem to appear, but classes are still present. For example, FLPackageStore is from the removed package FuelPackageLoader. However, if you browse that class it exists and it is under _UnpackagedPackage we really need to fix this.

I loaded SystemTracing-dtl.23.mcz into a Pharo 1.4 one-click. SystemTracer2 writeImage: 'clone.image' results in a 88 byte clone image and hanging image, non-interuptable, caused by the popping up of a deprecation warning. Switching off the deprecation blocking leads to a debugger popup when trying to add the specialObjectArray. #'==' doesn't seem to work as a equalsBlock in Pharo. replaced by equalBlock: [:one :two | one == two]; The method SmalltalkImage extraVMMemory has been deprecated use Smalltalk vm extraVMMemory Then the tracing finishes.
