Hi all, On this topic, I thought it may make sense to point back to an earlier SFWNV thread...

In any case, we're really following the upstream and what customers do with it, and they may want us to maintain multiple ABIs for a long period of time*. Or drop an intermediate release or two and have an "old popular" and "new popular" version integrated. Further, we can't make assumptions about what various numbers mean between the dots on API and ABI stability. Specifically, note that APR and httpd take different meanings from x.y.z. Another thread worth reading is this one: http://www.opensolaris.org/jive/thread.jspa?messageID=104674 It's a long read, but a lot of good thought went into it and it may help us avoid some future issues. Unfortunately, there's no good summary of where we ended up to my knowledge, but maybe it's clear to the rest of the team actually working on the integration. - Matt * This is analagous to what ISVs do with Solaris in a way-- they still support Solaris 8 because they have customer demand for it-- we may need to support Apache 1.3 for a long time due to demand-- not because either we or apache think it's the best approach -- Matt Ingenthron - Web Infrastructure Solutions Architect Sun Microsystems, Inc. - Global Systems Practice http://blogs.sun.com/mingenthron/ email: matt.ingenthron at sun.com Phone: 310-242-6439
