Re: [racket-dev] [plt] Push #21356: gr2 branch updated
mflatt has updated `gr2' from 5633895cf0 to 2b2de4ece6. http://git.racket-lang.org/plt/5633895cf0..2b2de4ece6 So, I see from this commit that you're planning to move the version number to 5.5. I think this is a mistake. We've been trying to be more conventional in our project managment, and I think we should stick with just incrementing the version. There's no reason that 5.1 can't be a significant improvement over 5.0, and skipping versions just adds potential for confusion.

[racket-dev] Equality test for Not-A-Number
What is the correct way to test for +nan.0 in Racket? For example, (= +nan.0 +nan.0) = #f. This seems to be the behavior specified in R6RS. In the science collection I implemented nan? using eqv?, which seems to work in Racket; but the result is explicitly unspecified in R6RS, which I assume means that it's up to the implementation. Which pretty much leaves eq? as the proper test. R6RS includes primitives like nan? and infinite?, which I included a long time ago in the science collection. Obviously one can use them from the r6rs libraries, but should they be moved into the racket language? Doug _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

The Linux Kernel, GCC, Subversion, Git, and many many other projects use this. 2. major.minor with no patch revisions. FreeBSD, KDE, Emacs, and other projects do this. 3. major.even-minor. with odd-minor indicating development releases. Gnome and various other projects use this. None of these in my experience have incremented by more than +1 (or +2 in case 3), even for significant changes. For example, GCC 4.5 added whole-program link time optimization and a plugin system (both very significant changes) over version 4.4.

Re: [racket-dev] FFI problem, possibly related to chaperones

That would lead to multiple `s16vector' structure types (which didn't occur to me when Robby asked if it would be ok to not share), and that might be what you're seeing. Okay, that makes sense. I talked to Robby a bit, and it sounds like the issue here is that unsafe pulls in all kinds of other stuff that makes DrRacket big. If I read the source correctly, then it would be possible to pull out the one-liner (define-struct cvector (ptr type length)) ... from unsafe/cvector.rkt and put it somewhere where it can be shared between DrRacket and user programs. It would appear to me that this would produce a single representation for cvectors, and perhaps by extension for the derived s16vector, etc. Am I understanding this correctly?
