Metacello / Iceberg / GitHub master to main renaming
by Sven Van Caekenberghe July 22, 2021

July 22, 2021

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

[Zdc]SocketStream>>#openConnectionToHostNamed:port: no longer signals am exception on macOS
by Sven Van Caekenberghe July 21, 2021

July 21, 2021

Hi, It seems that the following consistently crashes a recent/latest Pharo 9 image/vm on macOS: (ZdcSocketStream openConnectionToHostNamed: 'localhost' port: 12335) nextPut: 0; close. Command line, you can try it as follows: $ ./pharo Pharo.image eval "(ZdcSocketStream openConnectionToHostNamed: 'localhost' port: 12335) nextPut: 0; close. #foo" You can replace ZdcSocketStream by SocketStream, same result. Before, trying to connect to a non-existing host:port resulted in a ConnectionTimedOut: Cannot connect to 127.0.0.1:12335. Now, the code just returns and the bad stream is then used as if it is OK, which results in a hard crash. Furthermore, there is no backtrace nor log. Sven

July 19, 2021

Hi everyone, Last week I did these tasks: - Improve parametrized tests. - Clean up previous tests of Refactoring1 and Refactoring2 classes. Check these changes in the: PR #9599 <https://github.com/pharo-project/pharo/pull/9599> - Update scope manager to integrate. Check changes here: Scope branch <https://github.com/pharo-project/pharo/compare/Pharo10...Lin777:ScopeManage…> - Split migration from tests to integrate into Pharo. Check changes here: Migration branch. <https://github.com/pharo-project/pharo/compare/Pharo10...Lin777:MigrateRefa…> It will integrate after parametrized tests. - Migrate new refactorings, these changes are in the previous branch Tasks for this week: <https://github.com/pharo-project/pharo/issues/9142> - Continue migrating refactorings.

Serious NetNameResolver regression
by Sven Van Caekenberghe July 16, 2021

July 16, 2021

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'. ConnectionTimedOut: Cannot connect to 0.0.0.0:80 [ConnectionTimedOut signal: 'Cannot connect to ' , (NetNameResolver stringFromAddress: hostAddress) , ':' , port asString] in Socket>>connectTo:port:waitForConnectionFor: Receiver: a Socket[unconnected] Arguments and temporary variables: hostAddress: 0.0.0.0 port: 80 timeout: 30 Receiver's instance variables: semaphore: a Semaphore() socketHandle: #[198 113 243 96 0 0 0 0 240 65 61 2 0 0 0 0] readSemaphore: a Semaphore() writeSemaphore: a Semaphore() Socket>>waitForConnectionFor:ifTimedOut: Socket>>connectTo:port:waitForConnectionFor: ZdcSocketStream(ZdcAbstractSocketStream)>>socketConnectTo:port: ZdcSocketStream(ZdcSimpleSocketStream)>>connectTo:port: ZdcSocketStream class(ZdcSimpleSocketStream class)>>openConnectionToHost:port:timeout: ZnNetworkingUtils>>socketStreamToUrlDirectly: ZnNetworkingUtils>>socketStreamToUrl: ZnNetworkingUtils class>>socketStreamToUrl: I had a quick look at changes to Network-Kernel but had no luck yet. 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

Progress Report -> Refactoring Project - ( July 5 - July 9)
by Evelyn Cusi Lopez July 12, 2021

July 12, 2021

Hi everyone, Last week I did these tasks: - Add tests for migrated and non-migrated refactorings. Some important points here are: - the parameters are the transformation and refactoring classes, in some cases other values are necessary to make both classes compatible, such as the constructor method or the necessary extra arguments. - Some parameterized tests do not pass for the transformations (refactoring 2), these have flags that indicate exactly which part of the code does not work as in version 1. Changes are here: Branch of changes <https://github.com/pharo-project/pharo/compare/Pharo10...Lin777:Parametrize…> , and evolution of migration in this document: MigrationMap <https://docs.google.com/document/d/1vqYRdX3QDDugggxTpuN_0IvMozw9dzQZjq8yrF2…> - Split PR <https://github.com/pharo-project/pharo/pull/9546> into parametrized tests and migrated refactorings - Check the Deprecate class refactoring, I couldn't replicate the issue. (deprecate class: AthensDemoPresenter) Tasks for this week: <https://github.com/pharo-project/pharo/issues/9142> - Integrate parametrized tests into Pharo 9. - Add migrated refactorings into Pharo 10. - Continue migrating refactorings. Some of them are: - RBExtractMethodRefactoring (Finish to migrate) - RBFindAndReplaceRefactoring - RBExtractMethodAndOccurrences - RBExtractSetUpRefactoring - RBRenameMethodRefactoring - RBReplaceMethodRefactoring - RBInlineParameterRefactoring Best regards, Evelyn Cusi Lopez

Pharo Progress Report 2021-07-08
by Esteban Lorenzano July 9, 2021

July 9, 2021

So, this is it. The short term goals are now full of Pharo 9 release tasks, meaning we finished most of the technical issues remaining for the release: The M1 VM is available (and working in zeroconf), a new version of Pharo Launcher is ready to be unveiled all showstopper bugs fixed. Of course, that means more short term goals will emerge (but for next week!). As a consequence, a new medium term goal has arrived: We want to do a new iteration on the Pharo process, attempting to improve the release cycle and the general way we work. Short-term goals: - Release 9 - Release Pharo Launcher for Pharo 9 - Release Zeroconf for Pharo 9 Medium-term goals: - Review Pharo 10 process - Removal of GTSpotter - Removal of remaining GTTools Long-term goals: - Removal of Glamour - Removal if Spec1 - Migration of Calypso to Spec2 ## Last week - last bits on Spec2 leaks fixing - fixed some issues in iceberg. - work on zeroconf (supporting ARM) - make Open Build Service ready for Pharo 9 - Pharo Launcher ready for Pharo 9 release (including new P9 urls and M1 support) ## This week - prepare Pharo 9 release (announcements, reviewing site, final bugs, etc.) - prepare Pharo Launcher for Pharo 9 release - prepare Zeroconf for Pharo 9 release - work on Pharo 9 by example
