Ctrl+W in tabbed windows (GT inspector, browser/Calypso)
by Petr Fischer March 19, 2018

March 19, 2018

Hello! I assume that Ctrl+W is a widely used keyboard shortcut for closing windows or a tab, if the window is "tabbed" (it works in web browsers, some desktops, Linux, IE, Mac OS X...). But when I start up some exploration session in GT inspector, I have several tabs opened in a second - then, after Ctrl+W, not the actual tab, but the whole window is immediately closed, gosh... Same situation in "window groups" (when you created tabbed window group from browser/Calypso) - Ctrl+W behaves weird. Is everyone in comfort with the idea that Ctrl+W should close the actual tab, and if there is no tab in the window (or actual tab is the last tab), then close the window? Tested in Pharo 5, 6 and 6.1. pf

pharo bootstrap is in inconsistent state
by Alistair Grant March 19, 2018

March 19, 2018

Hi Pablo & Everyone, The bootstrap process seems to be in an inconsistent state at the moment as the scripts in: - Jenkinsfile and - bootstrap/scripts/bootstrap.sh don't match. bootstrap/scripts/bootstrap.sh has an error in it: ./pharo Pharo.image eval "PBBootstrap fromCommandLine bootstrap" --quit fails because the "--quit" option is valid for the st handler (executing a smalltalk file), but isn't recognised by the eval handler. Can someone, Pablo?, confirm what the status is, what it should be and what the next steps are? :-) Thanks, Alistair

Idea to manager package comment in better way
by Denis Kudriashov March 19, 2018

March 19, 2018

Hi. I look at hierarchy of PackageManifest and I was wondering that all these classes are commented but most of packages which they describe are not. Also interesting that most of manifest comments are same. Then I found that package comment is managed as special class side method #description which is generated when you call "aPackage packageComment: 'test'". Now the idea: will not it be better to manage package comment as manifest class comment? Manifest is already responsible to describe the package. So it looks logical to have "manifest comment = package comment". Also it will simplify code and remove duplication of texts. In addition it will add extra place indicating that package needs to be commented because uncommented classes are marked in the browser. What you think?

Performances of source code search on latest Pharo
by Cyril Ferlicot March 18, 2018

March 18, 2018

HI, We have a regression on source code search performances in latest Pharo. I am on Windows 10. With Pharo 6.1 it takes a few seconds to look for a string in all the image source code. With the latest Pharo 7 it takes minutes. To reproduce: - Open a playground - Type something - Select the text, right click - Clic on "Code search..." -> "Method source with it" https://pharo.fogbugz.com/f/cases/21612/Performances-regression-on-source-c… -- Cyril Ferlicot https://ferlicot.fr

Adapt ImageReadWriter hierarchy to need only pure binary streams
by Sven Van Caekenberghe March 17, 2018

March 17, 2018

https://pharo.manuscript.com/f/cases/21611 With the new File/Stream changes in Pharo 7, ImageReadWriter and subclasses broke because these classes are not yet capable of working with simple binary streams. I created a new test case (attached) to catch the functional degradation. For each image type (class) there are 2 tests, IO in memory and IO to file. For example: testJpegWriteReadInMemory | form bytes result | form := self pharoLogoFormNonTransparent. bytes := ByteArray streamContents: [ :out | PluginBasedJPEGReadWriter putForm: form onStream: out ]. "Without format detection" result := (JPEGReadWriter on: bytes readStream) nextImage. self assert: form bits size equals: result bits size. "With format detection" result := ImageReadWriter formFromStream: bytes readStream. self assert: form bits size equals: result bits size testJpegWriteReadUsingFiles | form file result | form := self pharoLogoFormNonTransparent. file := (self class name asString , '-pharo-logo.jpeg') asFileReference. file ensureDelete. (PluginBasedJPEGReadWriter on: file binaryWriteStream) nextPutImage: form. "gets closed ?!" "Without format detection" result := file binaryReadStreamDo: [ :in | (JPEGReadWriter on: in) nextImage ]. self assert: form bits size equals: result bits size. "With format detection" result := file binaryReadStreamDo: [ :in | ImageReadWriter formFromStream: in ]. self assert: form bits size equals: result bits size. file delete I have a bunch of changes that make all tests pass. They clean up some strange coding as well. I will make a proper PR later. Sven

Executive Summary of the recent FileStream Changes
by Sven Van Caekenberghe March 17, 2018

March 17, 2018

Executive Summary of the recent FileStream Changes In Pharo 7 Guille Polito recently committed a heroic set of changes that we were planning to do for a long time but were afraid to take on. The idea is to replace a couple of fat, overly complex, multi-functional, do-all classes with a set of simpler single purpose classes that can be combined as needed. The classes that we want to get rid of can be found in the package DeprecatedFileSystem, in particular FileStream, StandardFileStream, MultiByteFileStream, MultiByteBinaryOrTextStream and RWBinaryOrTextStream. The replacements are can be found in packages Files and Zinc-Character-Encoding-Core. Encoding and decoding characters to and from bytes is done using classes that you wrap around a more primitive binary stream. The same goes for buffering or translating line endings. For example, '/Users/sven/Desktop/foo.txt' asFileReference binaryReadStream. gives you a ZnBufferedWriteStream wrapping a BinaryWriteStream. While, '/Users/sven/Desktop/foo.txt' asFileReference readStream. gives a ZnCharacterReadStream wrapping a ZnBufferedWriteStream wrapping a BinaryWriteStream. To translate line endings, we would wrap a ZnCharacterWriteStream using a ZnCrPortableWriteStream. There are a couple of more specialised streams to cover special cases (like read and writing at the same time). SocketStream remains another fat, overly complex, multi-functional, do-all class, for which usable replacements exist in the form of ZdcSocketStream and ZdcSecureSocketStream, which are simpler, cleaner and binary only. Of course, switching is more than replacing one class with a 100% compatible alternative, that would give us the same complex result. The challenge is to use a simpler API as well, to rethink how the streams are used. You know, KISS. Of course, we are far from done and need more testing, debugging and help from as many people as possible.
