[Pharo-dev] [ANN] Pharo 6.0 released!
by Torsten Bergmann 06 Jun '17

06 Jun '17

Dear friends, Yes - really an impressive release. With many cleanups and new treasures in the image - but also many shiny new/updated external packages and projects (like Roassal, Polymath, Calypso browser, ... to name just a few). Thanks to all who helped - especially to the ones who cared and also worked on the not so interesting but often hard to solve issues or boring but necessary parts or infrastructure. The new git integration in Pharo and the included Iceberg tool will allow us to work with services like GitHub, GitLab, BitBucket - even own local git servers (for instance setups using Gogs.io). We can now manage project resources beside code, commit several packages at once and branch and merge as necessary. This really rocks! Many thanks also to all the contributors of the OpenSmalltalk initiative - it is also impressive how much progress was done on VM side. Also thanks to the ones writing new books, articles and tutorials so other can learn and enjoy such a fantastic dynamic and lively system. We still have a way to go for Pharo 7 and onwards. I'm eager to play with the new git based development process and interested on how we can manage to build our future Pharo based on the bootstrap efforts. Even when not finally there ... step by step it goes! Bye T. Gesendet: Dienstag, 06. Juni 2017 um 17:11 Uhr Von: "Esteban Lorenzano" <estebanlm(a)gmail.com> An: "Any question about pharo is welcome" <pharo-users(a)lists.pharo.org>, "Pharo Development List" <pharo-dev(a)lists.pharo.org>, members-consortium(a)pharo.org, "Seaside - general discussion" <seaside(a)lists.squeakfoundation.org>, "list ESUG Mailing" <esug-list(a)lists.esug.org> Betreff: [Pharo-dev] [ANN] Pharo 6.0 released! Dear World, The time has come for Pharo 6.0! Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback. This is our most significant release yet. Here are some highlights: - Pharo is now provided in 64-bit version in Linux and OSX and brings even better performance and stability (beware, 64bits version is a new technology and a small amount of tests is still failing) - A new code changes management system named Epicea for easier reviewing and recovering of your code easily - Integrated support for Git through an easy-to-use tool for repositories and commits management named Iceberg (as a preview for Pharo 6, it will be the default in Pharo 7) - The unified foreign function interface (UnifiedFFI) for interfacing with the outside world is significantly improved - The PharoVM is now part of OpenSmalltalk initiative - Introduction of object immutability, alternative bytecode sets and block closures independent of outer context - Pharo can now be bootstrapped from source code managed by Git - Pharo modularity is improved - Pharo is faster - The Dark Theme was improved and set as default color theme of Pharo These are just the more prominent highlights, but the details are just as important. We have closed 1474 issues in Pharo 6.0 (a more complete changelog can be found at https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo60Change…). While the technical improvements are significant (starting the transition to 64bits is a remarkable achievement), still the most impressive fact is that the new code that got in the main Pharo 6.0 image was contributed by more than 80 people. Pharo is more than code. It is an exciting project involving energetic people. We thank all the contributors of this release: Alberto Bacchelli, Alejandro Infante, Alexandre Bergel, Aliaksei Syrel, Alistair Grant, Andrei Chis, Ben Coman, Bernardo Contreras, Bernhard Pieber, Boris Spasojevic, Christophe Demarey, Clement Bera, Cyril Ferlicot, Dale Henrichs, Damien Cassou, Damien Pollet, Dave Lewis, Denis Kudriashov, Dirk Roeleveld, Eliot Miranda, Esteban Lorenzano, Esteban Maringolo, Evan Donahue, Federico Balaguer, Franck Warlouzet, Glenn Cavarle, Guillermo Polito, Gustavo Santos, Henrik Johansen, Henrik Nergaard, Hilaire Fernandes, Holger Hans, Jan Kurs, Jan van de Sandt, Johan Fabry, Juraj Kubelka, K.

Branch: refs/heads/Cog Home: https://github.com/OpenSmalltalk/opensmalltalk-vm Commit: 5ca1dfd981b768108e4c783a3f4a68984cd47dd2 https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/5ca1dfd981b768108e… Author: Eliot Miranda <eliot.miranda(a)gmail.com> Date: 2017-06-06 (Tue, 06 Jun 2017) Changed paths: M build.macos32x86/HowToBuild M build.macos64x64/HowToBuild M platforms/iOS/vm/OSX/sqSqueakOSXApplication+attributes.m Log Message: ----------- Fix regression in recent system attribute 1002 (OS Version) change on Mac OS X. Answering e.g. 10.10.5 breaks everyting that uses Smalltalk osVerison asNumber. So answer e.g. 1010.5 insteads so that Smalltalk osVerison asNumber = 1010. Typical image code looks like Smalltalk osVerison asNumber >= 1000 to identify Mac OS X over MacOS 9 et al. Mention how to get past an error when using lldb via ssh in the Mac HowToBuilds.

Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2222.mcz ==================== Summary ==================== Name: VMMaker.oscog-eem.2222 Author: eem Time: 26 May 2017, 3:24:23.911304 pm UUID: 72a78cd4-0916-4b02-afea-75e4ee736bac Ancestors: VMMaker.oscog-nice.2221 StackInterpreter: Add time primitives to answer the UTC and local microsecond clocks as updated by the heartbeat (as the Cog VM was originally before David changed the primtiives to access the time now). This access is much faster (of the order of 20 nsecs per invocartion vs 450 nsecs per invocatuon on a 2.3 GHz Mac Mini). Terf demands very fast clock times but is not concerned with fine granularity. The primitive numbers are 245 for UTC and 246 for local. primitiveMakePoint should fail if its /argument/ is not a SmallInteger or Float. Since the primitive is on Number we know the receiver is valid, and there is no point chekcing it. Checking the argument allows us to e.g. make 3D point using a cascade of @'s. Fix warnings for addIdleUsecs: on WIN32/64 (must not be marked exporrt to avoid declspec being added). reverseDisplayFrom:to: slightly improved if it does the addition at start of loop, not on every iteration. Cogit: primitiveCollectCogCodeConstituents should verify its argument (if it has one) and fail if not given a boolean. If it is given an argument it must remove it from the stack.

There must be a way to check if failure is due to existence of file (implemented via PrimErrInappropriate). If we would test existence afterward, the file could have been deleted in interim leading to another race condition.

OSProcess fork issue with Debian built VM
by Max Leske 04 Jun '17

04 Jun '17

Hi, We're building the pharo.cog.spur VM on Debian (32 bits, itimer, on 64 with compat libs). Unfortunately, we're running into one particular problem with OSProcess. Some primitives like primitiveFileStat work but forking a child process (e.g. with #waitForCommand) produces a segfault. We've tried to find a difference between our build and the VM downloaded from bintray but we weren't very successful. One difference we do see is that our libc6 version is 2.19, while the one used in the travis build is 2.15 (although both binaries use the 2.19 version at runtime). I'm aware that OSProcess hasn't been tagged as officially ready for Pharo 6 (which is where I'm using it). However, all of my tests with the prebuilt VM's have been successful. Do any of you have an idea as to what the problem could be? I've attached the stack trace below. One possibly interesting thing is that the stack trace is being printed in an infinite loop, i.e. the process isn't killed but the VM just keeps printing out the same trace. Cheers, Max could not open "[redacted]/crash.dmp" for writing.
