[Chicken-users] Need to do an install, any changes in the pipe line I should wait for?
I'm going to try getting Chicken 4.8.0.? installed in a corporate environment. This is not a nimble situation and if successful in getting the install approved I'll likely be stuck with that version for a long time. I've seen some messages on the chicken lists that look like some good progress on some important bugs. Should I wait a while before starting this process or is 4.8.0.5 a good target for the long term? Thanks. -- Matt -=- 90% of the nations wealth is held by 2% of the people.

I use CHICKEN a lot for my own webapps and the main problem I've found in using older versions of CHICKEN is in using eggs. You may want to be very careful to keep the source around for each version of the eggs you use in case an egg gets updated to be incompatible with the CHICKEN version you are on and you may not be able to get the old version after that. (Or maybe I missed a way to use chicken-install to get old versions and their old dependencies?) You may also not want to always be on the latest versions of eggs when setting up new environments which would mean being careful about managing your own versions of eggs; ie keep dev and production environments in sync without always updating the production environment. ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

[Chicken-users] undefined references in egg
I have a situation that resembles the following, where I have a definition |foo| that calls an undefined-by-the-module |bar|: ++ t.setup (compile -s t.scm) (install-extension 't `(t.so t.import.so)) -- ++ t.scm (module t * (import scheme) (import chicken) (define (foo) (bar))) -- Running chicken-install, I get the following warning and error: Warning: reference to possibly unbound identifier `bar' in: Warning:foo Error: module unresolved: t Reading the code, it seems the above warning is converted to a fatal error, though there may be cases where it does not. Here is my problem: I have an egg that, while initializing, defines bar, but bar isn't defined at compile-time, so I'm getting this error. This works when I compile the code outside of a module, but there seems to be an additional constraint when I wrap it around (module ...). Can I tell chicken-install that I know this symbol is undefined, and that things will be ok? Do I need to create a compile-time dummy definition? How should I handle cases where my egg uses but doesn't define a symbol in the runtime environment?

I think if you're just running Megatest and you won't be installing any new Scheme code it's enough to just test Megatest and if it works, stick with it. Usually, as new bugs get found and fixed these are when people run into unexplored corners of CHICKEN and getting in trouble, which you'll only run into when you're writing new code to run on that old CHICKEN, which just happens to expose the bug. There are always security issues which get discovered and may apply even to unchanging systems, but that's a constant with ANY system you set up and expect to keep running for a long time. A little grepping gives me the list of eggs below. I'll be doing some testing of 4.8.05 over the next week and wanted to hear from the dev's if there were patches in the queue I should wait for. Just ensure you have the latest released versions of all these eggs. Right now I'm intending to get 4.9.0 released soon, but this may take on the order of several weeks or even months. The roadmap in Trac is a (very rough) indication of where we're at: https://bugs.call-cc.org/roadmap As you can see, we've closed a whole slew of bugs and there are only a handful remaining. The critical/major ones need to be fixed before the release, the others might get lifted over to be fixed for 4.10.0, or in the stability cycle of 4.9.0. Also, there are some known bugs in the irregex version used in 4.8.0 which are (AFAIK) fundamental to the way the submatch extraction is implemented for the DFA-based matcher. The irregex in 4.9.0 uses a different implementation which does not have this problem. See for example https://bugs.call-cc.org/ticket/1047 This might be a problem for you if you intend to run user-supplied regular expressions with submatches. We're also slowly clearing up the small bugs found through the paranoia results of DEBUGBUILD. This may result in a few small fixes in existing eggs.

[Chicken-users] Chicken for python
