Headless VM and compositing -- was Re: Re: Can anyone get recent Pharo9 builds to work on Linux?

by Martin McClure

I figured out the compositing problem with the headless VMs on Linux. SDL, by default, requests that the window manager disable compositing. This behavior can be overridden starting with SDL 2.0.8. For more information, see https://github.com/pharo-project/pharo/issues/8220. For anyone else seeing this problem in KDE, there is a workaround. System Settings / Display and Monitor / Compositor contains an item "Allow applications to block compositing." This is on by default. When turned off, Pharo works better.

Problem debugging a test with #should:raise:

by Hernan Wilkinson

Hi all, I'm sending this mail to the three lists because it is an error I found in the three Smalltalks (Squeak, Pharo and Cuis) and maybe we could share the effort to solve it and the solution. The problem can be reproduce with this test: test1 self should: [ self error: 'something' ] raise: Error withExceptionDo: [ :anError | self assert: 'something different' equals: anError messageText ] If you run that test, it will fail of course. So if you go with the debugger to the context that signals de error (self error: 'something') and press restart and then over you will find the error. In the case of Squeak and Cuis, a new debugger is opened and you can not do anything with the original one. In the case of Pharo, the debugger stops working (in another try it opened a new debugger also but I could not reproduce it). I think the problem is related to the execution simulation but it is not a simple problem... Any idea what it could be? Cheers!

Yes, downloading fresh vm+pharo works (I was thinking I have a recent VM too -- sorry for adding to the confusion).

Re: Can anyone get recent Pharo9 builds to work on Linux?

by Martin McClure

Thanks, Esteban That method does get me a working Pharo, which I was having trouble with before (though I *thought* I'd tried exactly that...). However, it also somehow disables the compositor on my entire display, making it very hard to see where one (non-Pharo) window ends and another begins. Compositing comes back when I quit Pharo. The old VM doesn't exhibit this odd side-effect.

Progress Report -> Refactoring Project - ( December 21 - 24 )

by EVELYN CUSI LOPEZ

Hello everyone, I hope you have had a nice holiday. Last week I did these tasks: - Fix extract method and occurrences issues ( https://github.com/pharo-project/pharo/pull/8193) - Issue #8083 <https://github.com/pharo-project/pharo/issues/8083> - Issue #4429 <https://github.com/pharo-project/pharo/issues/4429> - Issue #4973 <https://github.com/pharo-project/pharo/issues/4973> - Issue #5269 <https://github.com/pharo-project/pharo/issues/5269> - Start to migrate extract method to refactoring2 and commander2 (as an experiment to review how effort we need to migrate all refactorings). - Create extract setUp and tearDown methods refactoring for TestCase classes (by the moment I have some issues in this new refactoring). Tasks for this week: - Finish to create extract setUp and tearDown methods. - Finish to migrate extract method to refactoring2 and commander2. - Fix undo refactoring issue. - Add option to limit classes where we replace senders of method to other method (https://github.com/pharo-project/pharo/issues/8087) - Fix push up issues (https://github.com/pharo-project/pharo/issues/2656 , https://github.com/pharo-project/pharo/issues/8132) Cheers, Evelyn

hi, I still have no problem with any of that. So you will have to be more specific : which image version, which VM version, which linux version.

I can confirm text input is severely broken backspace/del (tried on Linux buster, but it seems to be an image problem) -- control characters themselves get inserted into text pane. Type a string into a pane, ex. '123456789', position cursor somewhere in the middle, press del/backspace/ left&right arrows.

Hi Martin, I just did : wget -O- get.pharo.org/64/90+vmHeadlessLatest | bash ./pharo-ui Pharo.image And I had no problem at all (except a libgit2 version that will be fixed soon). I am using a Manjaro, but I do not see why it should not work on others.
