Re: [squeak-dev] The Inbox: Network-dtl.137.mcz
by David T. Lewis 24 Sep '12

There are problems with the new network support when running on Windows with a newer VM that provides IPv6 primitives. This preference allows the new network support to be disabled. Default setting is true, which enables the new network support (as is currently the case for a trunk image). It can be set false to disable new network support, and I think that this should be done for the Squeak 4.4 release image, otherwise we are going to cause problems for lots of Windows users. If no objections I will move this to trunk in a day or so.

OS version on squeakci?
by Frank Shearar 23 Sep '12

23 Sep '12

Hi Chris, Apologies if you've answered this before. What OS/version does squeakci run? It looks like it's running a CentOS of some description or other, I'm trying to write a build script for running a trunk image on a stack VM, and I'll at least need to know what version it is before anyone can give meaningful advice. In case David Lewis is reading, I'm seeing this: Installing Squeak-4.10.2.2614 for linux_i386 into /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm tar: Read 2048 bytes from - Installation finished. CHECKING squeakvm /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm: /lib/libc.so.6: version `GLIBC_2.11' not found (required by /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm) /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm: /lib/libc.so.6: version `GLIBC_2.7' not found (required by /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm) /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm: /lib/libc.so.6: version `GLIBC_2.15' not found (required by /var/lib/jenkins/workspace/LinuxStackVM/target/linux-stackvm/lib/squeak/4.10.2-2614/squeakvm) The machine in question has a /lib/libc-2.5.so, so perhaps that's causing the problem? The excerpt comes from [1]. The script that runs the build lives at [2]. Thanks, frank [1] http://squeakci.org/job/LinuxStackVM/7/console [2] https://github.com/frankshearar/squeak-ci/blob/master/linux-stackvm.sh

This will keep the tests green when the VM is updated to a more recent version. Dave On Sun, Sep 23, 2012 at 01:50:36PM +0000, commits(a)source.squeak.org wrote: > David T.

As of this commit we have only 9 failing tests! http://squeakci.org/job/SqueakTrunk/lastCompletedBuild/testReport/ One of those is entirely my fault: the HudsonBuildTools needs either fleshing out to pull in RB and friends or, better, stripping down to remove references to same. frank

Blogs, RSS, and JSON
by Chris Cunnington 22 Sep '12

22 Sep '12

Seems I spoke a little too soon recently about the ease with which the current The Weekly Squeak blog ( http://news.squeak.org ) RSS could be switched to JSON from XML. Yes, there is a plugin that aims that way. But it appears that is more for people who deploy Wordpress themselves. Not so much for people who just use it for free with Wordpress doing the deploying. Unless I misread these: https://developers.google.com/blogger/docs/2.0/json/getting_started#backgro… http://code.blogger.com/2011/09/blogger-json-api-now-available.html http://beautifulbeta.wikidot.com/json-feeds it looks like Blogger has a JSON API what with it being Google and all. So, the way to switch from a squeak.org that receives The Weekly Squeak as XML to JSON looks easiest by switching from Wordpress to Blogger. It's a thought. If somebody has a better grip on this, I'd love to hear it. Chris
