Alan Hargreaves' WeblogThe ramblings of an Australian STSC* Staff EngineerOpen vs Proprietry: An effort in mudslinging- August 28, 2007 I've just read an "article" by Carla Schroder on Enterprise Networking Planet, where she claims to know the real reason that closed and proprietary code exists. The point of the article appears to simply be that she doesn't buy ... into the "protect our preciouss IP" excuse because it is so overused. I see very little in the way of reasoned argument and example to support her stance. Instead I see a lot of mud slinging and cherry picked examples. We start off with the assertion that the real.http://blogs.sun.com/tpenta/entry/open_vs_proprietry_an_effort Something Different- August 27, 2007 I haven't mentioned it much here, but I was a musician many years ago and I kind of kept my hand in. I've been helping out at Brackets and Jam North on a monthly basis with the sound desk and I've also been doing the occasional walk-up performance. I took the next step over last weekend and recorded something I wrote a couple of weeks ago and registered myself as an artist on MySpace. Anyone who is interested can check my page and music at myspace.comalanhargreaves.

So what changed There was a bug in that the command-entry probe fired in both parent and child shell. This was a simple oversight that I should not have missed. I originally had the probe before sh forked, then moved it such that it fired after we knew we were able to fork (basically I didn't want it firing if we were not able to actually fork and run the command). Unfortunately, I forgot to...http://blogs.sun.com/tpenta/entry/sh_provider_update_command_entry sh provider update (changes and sparc available)- August 15, 2007 After discussions with Brendan and Adam, I've made a couple of changes to the provider. exec has been renamed to command, and script-begin and script-end have become script-start and script-done respectively. These changes are reflected in the documentation that is available at www.opensolaris.orgoscommunitydtraceshells In addition, I have rebuilt the x86 binary with this changes and provided a SPARC binary.

I've uploaded the diffs and an x86 sh binary to the "Providers for various shells" page. I'll do up a SPARC binary if there is interest in it. Note that the arguments for the entry probes for builtin, exec and function have changed. There is a link to the correct documentation on this page too. Have fun playing folks and let me know if you find any bugs. I would have had these up about 90 minutes ago, but my previous blog entry needed to be written.

Let me go through a few reasons why I did this one first. It's the one I was asked to do. The Bourne shell has been around for a very long time and there are, quite literally, millions of scripts that have been written in it, some of them very poorly so. Much work in the open source.http://blogs.sun.com/tpenta/entry/why_did_i_do_a binsh DTrace Provider- August 10, 2007 A couple of days ago Brendan was chatting with me on irc and we got to discussing such a beast. Mainly looking at something simple in the way of the python and perl providers that others have worked on. Well, to make a long story short (ok it will be longer later), I've coded up something that appears to work against the nevada clone tree of a couple of days ago, and logged RFE 6591476 to track it. I'll be putting the diffs up in the next day or so, but for a teaser, here is the...http://blogs.sun.com/tpenta/entry/bin_sh_dtrace_provider |
