Re: [Pharo-dev] Dirty Seaside-pharo-core and Seaside-pharo-core-backtracking

by Johan Brichau

It seems there were still some class extensions in the package Seaside-Pharo20-Core that were using the '*seaside-pharo-core' method protocol name. This is because the package was originally just a copy of the Seaside-Pharo-Core package, and there was a (now solved) bug in Nautilus at the time the package was renamed. It's fixed now in the #bleedingEdge Johan On 16 Feb 2014, at 15:26, Max Leske <maxleske(a)gmail.com> wrote: > Hmâ¦ donât really know but I guess they could come fromt the configuration.

Hi GÃ¶ran, Thanks a lot, I've turned your email into a Pharo issue: https://pharo.fogbugz.com/f/cases/12894/SSL-plugin-enhancements I won't be able to process this by myself, but it will get integrated once the right people get together.

I haven't looked through them all in detail, so here a bit of manual cherry picking is needed.

The errors still left are: testSSLSockets, testSocketAccept, testSocketConnect.

Re: [Pharo-dev] 100% CPU usage on image resume

Hi Holger, I make an issue out of this (I hope you can access this): https://pharo.fogbugz.com/f/cases/12893/100-CPU-usage-on-image-resume but...

DiskFileSystemTest testEntryAt

by Nicolai Hess

Once I reproduced that error on a windows machine. It happens if pharos clock is behind the system clock. Creating a file results in a created tmestamp in the future. And comparing that time with "DateAndTime now" fails (now is smaller than the file timestamp). I couldn't find out, why pharos clock was behind, but somtimes this difference were several seonds.
