Thank you for the follow up on this. This kind of problem can be very difficult to find and debug!

Problems with Epicea on Pharo 7

by Cyril Ferlicot D.

Hi, I have a little problem with Epicea and there is some things I would like to discuss. My problem is that I have a Jenkins job downloading a Pharo 7 image, loading inside a little project via an eval command launching a Metacello script. Then I launch tests. And then I archive the image. When I get this image and try to open it with the --no-default-preferences option, I get a window saying that I lost changes and asking if I want to recover them. The only two commands I launched on Jenkins where: ./pharo Pharo.image eval --save ' Metacello new blabla...' and ./pharo Pharo.image test --junit-xml-output '(bla).*' So here my first problem: I don't see why I would have lost changes. Second problem: I did not include pharo-local/ in the archive. So there is no ombu log next to the image. Even if I had a crash on the Jenkins, I would not expect to get this recovery message since I have no epicea log and cannot recover anything. At most I would just expect an #inform: saying "A crash was detected but cannot be recovered" Third problem: This is the case where I have the --no-default-preferences option. If I don't have this option, the image open, the epicea message open and I can do nothing because my Pharo froze. I cannot close the message. I cannot interrupt (ctrl + .). I can just force close the image and the loading of my settings never ends. If I am right on the problems I'll open bug entries about them. Thank you in advance. -- Cyril Ferlicot https://ferlicot.fr

generated webdoc?

by Guillermo Polito

Hi all, I know that we had before the generated webdoc from pharo releases in the file server (files.pharo.org) But I cannot see it anymore. Do we still have it hosted somewhere? We were planning to use it as online material for a course. I know that it is mostly not needed, but newby students need somehow to bootstrap themselves :).

Re: [Pharo-dev] Pharo6 with Ubuntu and OSSubprocess/threaded heartbeat crashes and problems

Now I know the reason for the crashes. I did a lot of log writing when creating my reports (they use OSSubprocess). This was only for debugging. Removing them removed the problem.
