Since these productions are referenced everywhere, they get used a lot, and I'm really happy I'm using the same code to run them whereever they appear. The names of toplevel-entry points for library units can now contain arbitrary characters. Since the naming conversion is not backwards compatible, bootstrapping may be a bit tricky. This means if you get errors mentioning /C_foo_2d1_toplevel/ build your chicken, make spotless and rebuild it again with the binary you got from the first step. When I first encountered this problem, I tried using git bisect. It was the first time I'd used git bisect. I had no luck doing so, because each time I performed the bisect I failed to compile chicken with itself. It was fun to learn how to do that, I'm sorry this change kept me from running the experimental branch for so long. Now I know what to do, at least. :-) Some useless warnings have been removed. I'm also really happy with this one. It makes my build output much cleaner, so I can spot legitimate warnings.

[Chicken-users] embedding question / seg fault
OS X 10.6.6 with Chicken 4.6.0 Hi, I was trying our the embedding example under CHICKEN_yield here: http://wiki.call-cc.org/man/4/Embedding I keep getting a seg fault and this seems to be the offending line: CHICKEN_get_error_message(buffer, 255); If I comment that out there's no seg fault. I looked at this post: http://www.mail-archive.com/chicken-users@nongnu.org/msg11218.html but I don't see what the resolution would be. Would it be easier to just avoid using define and stick to define-external? Is there any particular reason to use define? FYI, I'm trying to call Chicken commands from Python using Cython. Thanks, -Dave ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] utf8 open tickets
I have two open tickets against the utf8 egg: https://bugs.call-cc.org/ticket/423 https://bugs.call-cc.org/ticket/480 Both of them are simple fixes, one of them is causing several packages not to compile against the experimental branch, which Christian has just begun nightly builds for: http://pestilenz.org/~ckeen/salmonella-report/ Alex, will you fix these tickets? would you like help with them?

[Chicken-users] sqlite3 egg still failing in experimental branch
Thomas, The sqlite3 is still failing to compile in the experimental branch: http://pestilenz.org/~ckeen/salmonella-report/2011-01-14/sqlite3.html Will you apply the patches I sent you to the sqlite3 egg? Since sqlite3 won't compile, I can't test my own packages against the experimental branch. I believe a few other packages won't compile as well. After Felix e-mailed me the reference for the fixnum arthimetic procedures, I was able to modify genturfa'i to use those procedures rather than declaring fixnum. Would you like a new patch that uses this same approach in sqlite3? Disabling the fixnum declare but replacing you maths operations with fixnum versions? What do you need to get the sqlite3 egg updated to compile against the experimental branch? -Alan -- .i ko djuno fi le do sevzi ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] srfi-19, srfi-29 not compiling in experimental branch
Kon, Would you update srfi-19 and srfi-29 to compile against the experimental branch in chicken?: http://bugs.call-cc.org/ticket/481 http://bugs.call-cc.org/ticket/482 The patch is very simple, getenv has been deprecated in favor of get-environment-variable. These are the only two srfi-* eggs not compiling against experimental, I'd love to see all of the baseline/infrastructure eggs working against this branch.

I get a different error, but it is likely to be caused by the same problem: the compiler optimizes the compiled procedure for `CHICKEN_get_error_message' into a leaf routine (which uses different calling conventions than normal procedures). I have disabled this optimization for all external callback procedures, since the calling convention may not change in this case. See the experimental branch.

Or maybe some genetic modification to reduce the necessary amount of sleep? I'd like to pose a question to the list about this issue, because it results from the way development is done in Chicken Scheme and perhaps someone has insight into the issue. I'm suffering from priority inversion on this issue: jbogenturfa'i requires the experimental branch to run[1][2], while one of it's dependencies, sqlite3, won't run on the experimental branch.[3] The fix to sqlite3 is easy, and I've provided patches. There isn't any reason Thomas' priorities should be mine, however, and in this case they aren't. My options seem to be to convince Thomas that he should be running at a higher priorty or ask Mario for a sqlite3-experimental egg in the repository and fork sqlite3. I don't consider a fork a good idea, but if I had to fix this issue today, I can't think of a better one either. It is easier to accomplish that either of Thomas' above requests. :-) How has this situation been handled in the past? Can someone sugest a solution that doesn't require Thomas to raise his scheduling priority but allows me to have a sqlite3 that compiles in experimental? I'm fortunate to be in a position where this issue isn't urgent--I'm the only one running jbogenturfa'i and I can keep my patches in my local repository. I may not always be in such a fortunate position.

Those who will probably won't object to (temporarily) applying a patch; they're already running an unstable version of Chicken. Just provide instructions in the egg's documentation. How has this situation been handled in the past? To my recollection this exact situation hasn't occurred before. Anyway, I wouldn't consider it too big an issue since most regular users are using release versions, or at best snapshot development versions. People interested in the bleeding edge are expecting possible breakage already, so I don't think it's that big a deal, really. If you are desperate and Thomas really can't cope with your pace of development you might perhaps want to negotiate (co-)maintainership of the egg with him, if he's open to that.
