Re: Serious NetNameResolver regression

by Gabriel Cotelli

Just doing NetNameResolver primStartLookupOfName:'unknown-stfx.eu';primNameLookupResult produces the bogus result. And both methods only call primitives in the SocketPlugin. So I think that no image code is responsible for the behavior change.

Serious NetNameResolver regression

by Sven Van Caekenberghe

Hi, It seems that we have a serious NetNameResolver regression: instead of signalling an exception, a bogus value is returned. Pharo 7: [ NetNameResolver addressForName: 'unknown-stfx.eu' timeout: 10 ] on: NameLookupFailure do: [ :exception | exception ]. "NameLookupFailure: cannot resolve 'unknown-stfx.eu'" Pharo 9: [ NetNameResolver addressForName: 'unknown-stfx.eu' timeout: 10 ] on: NameLookupFailure do: [ :exception | exception ]. "0.0.0.0" This is bad. What is even worse is that the following kills your image without leaving any trace (on macOS): ZnClient new get: 'http://unknown-stfx.eu'. Because it tries to connect to 0.0.0.0 On linux, at least there is a backtrace: sven@stfx-1:~/pharo$ rlwrap ./pharo reddit.image NeoConsole repl NeoConsole Pharo-9.0.0+build.1528.sha.29269ecfac2cbf6a56dfee232b7d3355e5cb77bd (64 Bit) pharo> NetNameResolver addressForName: 'unknown-stfx.eu' timeout: 10. 0.0.0.0 pharo> ZnClient new get: 'http://unknown-stfx.eu'.

Because of this running Zinc HTTP Components tests on macOS Pharo 9 also kills the image (ZnClientTest>>#testIfFailNonExistingHost). Of course, NetNameResolverTest does not do enough. Sven

[ANN] Pharo 9 released!

by Esteban Lorenzano

Dear World and dynamic language lovers: The time has come for Pharo 9 (https://pharo.org/) ! Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback. Here are the key features of Pharo 9: Full redesign of the Spec UI framework (new logic, application, style, GTK3 back-end) New tools: new playground, new object centric inspector, new object centric debugger. better and new Refactorings class comments are now written in Microdown format (Markdown compatible) classes now can be defined using a "fluid" api (Preview) New completion framework that adapts better to edition contexts and is customizable Fast universal non-blocking FFI which now uses libFFI as backend. Pharo now supports Windows, OSX, Linux (Ubuntu, Debian, Fedora, openSUSE, Arch, Raspbian) and multiple architectures (Intel/ARM 32/64bits). Virtual Machine Idle VM Support for ARM 64bits Support for Apple M1 More than 3000 tests Built for Ubuntu 18.04, 19.04, 20.04, 21.04, 21.10; Debian 9, 10, Testing; Fedora 32, 32, 34; openSUSE 15.1, 15.2, Tumbleweed; Manjaro; Arch Uses SDL 2.0 as back-end by default. It supports extended event handling, including trackpad support. General speed up due to compiler optimisations and UI simplification. And many, many more tests. These are just the more prominent highlights, but the details are just as important. We have closed a massive amount of issues: around 1400 issues and 2150 pull requests. A more extended changelog can be found at https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo90Change…. While the technical improvements are significant, still the most impressive fact is that the new code that got in the main Pharo 9 image was contributed by more than 90 people. Pharo is more than code. It is an exciting project involving a great community. We thank all the contributors to this release: Aaron Bieber, Ackerley Tng, Alban Benmouffek, Ale Cossio, Alexandre Bergel, Alistair Grant, Allex Oliveira, Angela Chia-Ling, Arturo Zambrano, Asbathou Biyalou-Sama, Ben Coman, Benoit Verhaegue, Carlo Teixeira, Carlos Lopez, Carolina Hernandez, Charles A.

Re: Git Method Timestamps

Hi Sean, > On 14 Jul 2021, at 23:21, sean(a)clipperadams.com wrote: > > What is the git equivalent to CompiledCode>>#timeStamp? (which returns an empty string) That does not exist anymore: maintaining a timestamp in source code does not make sense in a time where everything is under source code management. Basically because you could forget to update the timestamp when you change something elsewhere. However, for source code (classes/methods) to which a repository is connected, you can ask for the git history, which is much more powerful. I don't know how to do this programmatically, but in the IDE click on the method, menu > History. Here is an example: Regards, Sven

Re: Metacello / Iceberg / GitHub master to main renaming

by Martin Dias

Hi, Some months ago, I added an FFI call to libgit to get this information. Here: https://github.com/pharo-vcs/libgit2-pharo-bindings/pull/40 But after this PR is merged, Metacello should use it, and I didn't research how to do it (I never contributed to this project yet...). Maybe somebody can assess how to do it?

Metacello / Iceberg / GitHub master to main renaming

by Sven Van Caekenberghe

Hi, For new GitHub projects the default branch is now main instead of master. There is however code in Metacello / Iceberg / ... that tries a number of options if no branch is specified, but it is not yet aware of this change. Specifically: This does not work ./pharo reddit.image metacello install github://svenvc/Reddit BaselineOfReddit instead you have to say ./pharo reddit.image metacello install github://svenvc/Reddit:main/ BaselineOfReddit It took me half an hour to figure this out ;-) Sven
