[Pharo-project] About working with XML

by Jorge Silva - 10Pines

Hi guys! I'm new to this group, so nice to meet you. I'm starting to work with Pharo and my first issue is how to work with XML. Can someone tell me about some package or "framework" to work with XML (parse it and serialize objects to it). Any help would be appreciated. Cheers, Jorge

Re: [Pharo-project] OSProcess - working on gnuplot

I attached gdb to the VM. When running UnixProcessTestCase the VM crashes with: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000083 0x000e7e9d in resume () (gdb) bt #0 0x000e7e9d in resume () #1 0x4b04264b in ??

OK, I'll stick to this VM version. I compared to the Squeak trunk image and the very same test cases crash the VM. So at least the crashing problem (on Mac) is not likely caused by a Pharo-specific change. Adrian On Nov 18, 2009, at 16:18 , David T.

I think that's from about November 2005, so a bit out of date. The source is on SqueakSource OSProcessPlugin project if you want to see what has changed since then. Nevertheless it should still be good enough to get most of the tests to pass, so I would not worry about the version difference for now. Dave

Hmm... the systemversion change somehow did not work. so the updates are not loaded past 11047. Need to check.

Hi Dave, OSProcess accessor osppModuleVersionString ==> '4.0.1' I get the same result with the Mac 4.2.2beta1U VM. Adrian On Nov 18, 2009, at 14:33 , David T.

Re: [Pharo-project] OSProcess - working on gnuplot

Dave, It would help to knock the MVC workspace out of the offending #initialize method and re-save the packages. In my experience, that simple change make the load hassle-free vs. the current situation.

I would think that the fact that you have gotten the VM to crash is an indication that you have located the plugin bundle though ;) Just to double check, try doing this in a workspace: OSProcess accessor osppModuleVersionString ==> '4.3.3' The #osppModuleVersionString method will make a call to the plugin without doing much else, so that is a way to verify that you have loaded the bundle. Also, if the version is not fairly close to the latest (4.3.3) it might be an issue. On OS X, I don't think that you have the AioPlugin or XDisplayControlPlugin available, so some of the tests will fail as a result of this. I don't have time right now, but I'll try removing these plugins from my system and see what happens. But it should be a few simple test failures, not the kind of problem you are seeing.
