Only one remark, which is not node.js specific at all: As has been discussed previously in this thread, V8's version numbers do not try to make any statements about binary compatibility. That means to avoid run-time breakage, *any* applications compiled against V8 must play it safe and depend on *exactly* the V8 version they were compiled against.
When you're *lucky*, something that's compiled against, say, V8 v3.11.10.17 will also work with v3.11.10.18, but there are *no guarantees* that all 3.11.10.x versions are ABI compatible. (Most of the time they are, because most stability/security fixes do not change the ABI, but sometimes they're not, because when we decide to backport a fix we do not even check for ABI compatibility.) When you let your node.js package depend on "V8 >= 3.11.10", it again comes down to luck: If you are careful to release matching updates for both packages at the same time, and if all of your users happen to always install matching sets of updates, everything will be fine. If, however, for whatever reason someone ends up with the older node.js package and e.g. V8 3.14.x, chances are their node.js will not work. (Again, no guarantees either way -- it might happen that our ABI won't change between 3.11 and 3.14, or that at least it doesn't break backwards compatibility, but nobody is ensuring this or even trying.) If my package manager installed two packages on my system which are not compatible given their respective versions, I would consider that a bug ;-) On Fri, Jul 27, 2012 at 11:53 PM, Floren Munteanu <[email protected]> wrote: > OK, the finalized RPM's are now published into my public repository: > http://rpm.axivo.com > > Jeremy, Jakob, > > I dare asking this question here since it looks like you have close > knowledge about Node.js also. > I opened this topic on nodejs list: > https://groups.google.com/forum/?fromgroups#!topic/nodejs/lhKN6aFxT6g > > If you have any inside, please reply there.
