Re: FileDoesNotExistException - FileBrowser opening on Mac M1
by Stewart MacLean Dec. 26, 2021

Dec. 26, 2021

Hi All, This is my first post! Sadly it is to report an issue with the FileBrowser on the Mac M1. I am encountering this exception - FileDoesNotExistException. These are the culprits: [image: image.png] I have seen a similar error reported on Windows. Looks like Pharo can't access the attributes of these files? https://github.com/pharo-project/pharo/issues/3571 I'm exploring Pharo with a view to migrating my VisualWorks project of many years, as support for M1 looks like it might be a way off, so not off to a good start! I managed to work around it, by deleting these two files (not from the disk!) in the debugger, before it tried to fetch the attributes. Interestingly, when in the debugger it showed N/A and 0 for the attributes, as these are system files I'm guessing.

CLAP - how to get instance of command without executing it
by bajger＠gmail.com Dec. 25, 2021

Dec. 25, 2021

Hi Pharoers! I have following problem in CLAP and would be glad to get your guidance: I have following method on command class (sub-class of ClapApplication):\ `PhLImageKillCliCommand>>osShellCmdString` `(arguments at: #all) value ` ` ifTrue: [ ^ (self killImageCmdStringFrom: nil) ]. ` `^ self killImageCmdStringFrom: self imageName` And I want to implement unit test, that would test expected output of this method. As you can see, implementation is dependent on arguments attribute #all. And here is a problem in unit test: `testOsShellCmdString`\ `| killCliCommand aMatch| aMatch := (context arguments: #('launcher' 'image' 'kill' '--all')) match. killCliCommand := PhLImageKillCliCommand new. killCliCommand setArguments: aMatch.` `self assert: killCliCommand osShellCmdString equals: ''.` This doesn't work, since `arguments at: #all` gives NotYetImplemented exception. So I don't know, how to "wire" toghether instance of command (without executing it) and needed arguments (a match). Any advice on this? ![ObrÃ¡zek](https://media.discordapp.net/attachments/819245127310114886/922498381358723123/unknown.png)

pharo9 tools moldability
by Danil Osipchuk Dec. 20, 2021

Dec. 20, 2021

Dear all, Being a long time smalltalk user (meaning I'm crafting tools for my own usage for domains I'm working with) I always relied upon the environment itself to interact with models to spare time creating user interfaces. Besides plain inspectors I used metafacilities where possible -- seaside, then omnibrowser and lately glamour toolkit in pharo8. Now it seems the glamourous core is not part of pharo9 anymore. Meanwhile pharo9 looks increasingly neat and I would like to make a transition but having tools in pharo8 holds me back. I would be grateful for any pointers to help me to get started with the moldable inspectors pharo9 - papers, talks, online discussions, etc. I can likely figure it out on my own, but having an overall understanding of the approach concept would save an effort and shorten the trial and error phase. (maybe I'm overcomplicating it and just having browsed around inspector code pragmas is enough to get started) regards, Danil

Hardening Zinc's Core HTTP Server
by Sven Van Caekenberghe Dec. 2, 2021

Dec. 2, 2021

Hi, Zinc HTTP Components [https://github.com/svenvc/zinc] has been a part of Pharo since version 1.3 (2011). It is an open-source framework to deal with the HTTP networking protocol, modelling all aspects involved. It also offers both client and server functionality. The reliability of the code base has improved steadily over the years, thanks to virtually all Pharo developers using it, directly or indirectly. Over the summer a number of issues that popped up after Pharo 9 was released were resolved. The robustness of the core HTTP server is one important aspect. To put this quality further to the test, I deployed two servers with the same demo Seaside application, Reddit.st, open to the internet, without any further protections. - On Amazon AWS: http://34.245.183.130:1701 - On Microsoft Azure: http://51.137.72.94:8080 The application's source code can be found at [https://github.com/svenvc/Reddit] For the technically curious there are also deploy instructions at [https://github.com/svenvc/Reddit/blob/main/DEPLOY.md] The demo app itself is described in an older article [https://medium.com/@svenvc/reddit-st-in-10-cool-pharo-classes-1b5327ca0740] Note that, by definition, there is no HTTPS/TLS variant. If you manage to break this server with (a) malicious request(s) in such a way that you can explain what you did for others to confirm your approach, you not only help me/us improve the code, but earn eternal fame as well ;-) Sven PS: I hope I won't regret this, I am looking for constructive criticism. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org
