Another new Blog

by Guillermo Polito

Hi all! Probably some of you already saw my tweets about it: http://playingwithobjects.wordpress.com/. I'll be writing there stuff, whatever I want to write :). Probably in this first few weeks, documentation about the Pharo bootstrap project. I didn't make it public before because I wanted to see if I had time and will to write. And it seems I have both :). So far, three posts: - how the objects are formatted in memory for the VM - image based vs non image based environments - bootstrap introduction Please, do not hesitate to leave me your comments. I'm very far from being a gurÃº on any of the things I write, so do not expect that. Even better: expect me to make mistakes and write wrong things, and please correct me :). Saludos, Guille

Hi Igor, I am not sure I understand. This would still not test the final logic, would it?

Re: [Pharo-users] ZnClient>>#close & socket semaphores

Sven - Sorry for the delay in getting back to you about this and I know Igor has submitted a new method for automatically expanding the semaphore table so the issue may be moot but I thought I'd respond below anyway.

In fact at this time I'm guessing that that may be the culprit because it happened again yesterday while not using any of the ZnClient functionality. When the error was raised I did inspect the ExternalSemaphoreTable unprotectedExternalObjects and a significant portion of the slots in the array were nil. Maybe I'm looking at the wrong thing.

So I think it implements most of their API. Also can run it behind nginx as needed.
