Epicea: Revert the removal of a class
by Cyril Ferlicot D. Aug. 2, 2017

Aug. 2, 2017

Hi, Today I tried to remove a class, go in Epicea and revert the removal of the class. At the end the class was here but with no methods. Is that the normal behaviour? I think it is a bug but since I don't really use Epicea a lot for know I am not sure. Have a nice day. -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques PrÃ©vert 01, 59650 Villeneuve d'ascq France

Calypso browser and categories?
by Mariano Martinez Peck Aug. 2, 2017

Aug. 2, 2017

Hi Denis, I wanted to give a serious test to Calypso, that is, start using it all day long. However, there is a critical thing I am missing, which is the grouping of categories (inside packages). I do not want to start discussing again packages vs categories and what are good and bad practices. I do have a few packages and each package may have several categories inside. So... seeing all classes together inside a package is not nice for me. Is there a way in calypso to auto-escope to category level? I mean... say my package is XXX and I have categories XXX-A and XXX-B. I know I can go to left side column and with the tree, I can go to XXX-A and I get what I want. But, for example, when I browse a class of XXX-A, the "focus" of the left side column is XXX and not XXX-A. So I am wondering if we can make it auto-scope to the category everywhere in Calypso. Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Lots of "UTF8InvalidText: Invalid utf8 input detected" from OMBU
by Mariano Martinez Peck Aug. 2, 2017

Aug. 2, 2017

Guys, I am getting "UTF8InvalidText: Invalid utf8 input detected" quite frequently on Pharo 6.0 which come from ombu background job. Has anything seen this too? Quite annoying... This is not the first time I hit it. This time I analyzed a bit why it was failing and it's because I removed a method manually...I mean, I did MyClass removeSelector: #myMethod And the omEntry is a EpMethodRemoval which represents the exact method I deleted... Also I can see the MultiByteFileStream internal 'collection' is full of none ascii things. I can share a fuelout as well as the image with the files if you want. I can also share the ombu file in question.

Re: [Pharo-dev] [IMPORTANT] Following changes in the bootstrapping process
by phil＠highoctane.be Aug. 1, 2017

Massive. What is in the super small image? Is Hermes going to be a generic binary content loader? Phil On Aug 1, 2017 11:58, "Pavel Krivanek" <pavel.krivanek(a)gmail.com> wrote: Hello, we are checking a huge pull request #177 (https://github.com/pharo- project/pharo/pull/177) that will change some basics of the bootstrap process: Now we will bootstrap a smaller image that will not include compiler/parser. Compiler and related packages are exported and loaded using a binary exporter named Hermes. The compiler is then used to load FileSystem and Monticello. The rest of the bootstrap process will be the same as before. As the result we will have faster bootstrap and better system modularization and possibilities. It required some modularization efforts: - simplified initialization scripts - Use Zinc converters and encoders instead of FilePathEncoder and old TextConverter - Use Stdio instead of FileStream - Using File instead of FileSystem - Deprecated FileStream & childs (Moved to Deprecated70) - Extracted Path classes to their on package: FileSystem-Path - Moved OpalEncoders to their own package. They are required by the runtime (not only for compilation) - Introduced AsciiCharset in the kernel to answer to #isLetter #isUppercase and so on without requiring full Unicode tables from the beginning - Cleaning up a bit the full exception logging infrastructure (streams, transcript, files, stack printing...) - Split Ring methods required for system navigation to the Ring-Navigation package - Remove usages of #translated in the kernel - Refactored the bootstrapping classes to remove duplications - Cleaning up dependencies in CompiledMethod>>printOn: - fix path printing We need to merge these changes at once and of course it can cause some conflicts with the existing pull requests or external code. Anyway, we need to merge it as soon as possible. So please, try to look at the PR and test the resultant image [1] to avoid some major problems.

Launcher and Pharo 6.1
by Sean P. DeNigris Aug. 1, 2017

Aug. 1, 2017

Is it safe to replace the Launcher VM with the one required for Pharo 6.1? I.e. is that VM backward compatible with a Pharo 6.0 image? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Launcher-and-Pharo-6-1-tp4957770.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Out of curiosity: What is the impact on the Pharo Project? Is the build process is interrupted?
