I agree that your suggestion is better, but for that reason, we have been dealing with this for more than 2 years. So: - hacking the image is not the best solution but it can be integrated in pharo in less than 5 minutes and working out of the box. Ok, we do not use the plugin if it is UNIX directly...even if that distro may be working - hacking the image is better than crashing the system while doing something as basic as a simple commit. VM should crash as less as possible. Providing such script (the one you say), integrate them in the pharo one clicks, testing it in several OS, and of course, how to CODE that piece of C/Shell or whatever you use, and how to know if the installation of libuuid is broken. I think that pretending this solution is why this problem is present since 2 years already. Hacking the image (or fixing a basic crash) can be done in 5 minutes and it is muuch better than a crash. If you, or someone, come after with a better solution, there is no problem. Such changes can be reverted in another 5 minutes. We are flexible ;) Just my opinion Mariano > > 2Â¢ > Eliot > > >> Dave >> >> >> >

IMO, this would be better than either crashing after startup or hacking the image to avoid the primitive because of a platform error. The issue then is how to check. One straight-forward way would be for the start-up script to invoke a small C program that invoked libuuid in exactly the same way as the UUIDPlugin, and if this fails then the startup script can warn. The issue remains how to correct the installation once the error has been detected. 2Â¢ Eliot > Dave > > >

Re: [Pharo-project] Issue 3262 in pharo: Debugger enhancement to open in a background process when the UI process is busy

Updates: Summary: Debugger enhancement to open in a background process when the UI process is busy Comment #2 on issue 3262 by stephane.ducasse: Debugger enhancement to open in a background process when the UI process is busy http://code.google.com/p/pharo/issues/detail?id=3262 Tried to rescue some of Eliot Miranda improvement for the debugger. Strangely enough the functions introduced by eliot got removed and not invoked in latter versions. Now invoking the debugger crash the system probably because there is an problem with the semaphore or other. I just save this to avoid to redo everything. Attachments: Debugger.1.cs 4.4 KB
