#112 | fixed | "Trivial" is not an indicator for "Priority" | ||
Description |
We have "critical", "major", "minor" and "trivial" as priorities for trac tickets. "Trivial" sounds more like a difficulty level. Since the reporter theoretically has no means to know if the ticket is trivial or not to solve, he/she cannot tell if it is trivial or not. I suggest changing "trivial" to "not urgent at all". |

#113 | fixed | Crunch egg: bug in define-crunch-primitives / define-crunch-callback | ||
Description |
In line 78 of crunch.scm , pair? is called with two arguments: (and (pair? (car p) (c (r '+>) (cadr p))))))) The version of Crunch is svn trunk (but that line is the same in version 0.7.2). I tested it with Chicken from git, commit 43a11082ddc109bfe1b4fdb400b6079ca64d024a The following is a report of my attempt to debug the problem; since I'm new to Chicken Scheme, I may have made several silly mistakes along the way... The following code (crunch-bug.scm) does not compile (I suppose I undertood how to use define-crunch-primitives and define-crunch-callback): (cond-expand (crunched (import crunch)) (else (define-syntax crunch (syntax-rules () ((_ body ...) (begin (display "Crunch not working") body ...) ) ) ) ) ) (define-crunch-primitives ((foo int) -> void)) (define-crunch-callback (foo (int i)) void (display (format "Here's your int: ~a ~%" i))) (crunch (define work (lambda (max) (do ((k 0 (+ k 1))) ((>= k max)) (foo k)))) ) (work 10) I tried fixing line 78 of crunch.scm, changing it to: (and (pair? (car p) (c (r '+>) (cadr p))))))) But then the code and declarations for the function (foo in the example above) are not generated properly in the C++ file: $ csc -c++ -D crunched crunch-bug.scm Warning: reference to variable `unquote' possibly unintended crunch-bug.cpp: In function ‘type37 f36(type35)’: crunch-bug.cpp:58: error: ‘crunch_callback14’ was not declared in this scope crunch-bug.cpp: In function ‘void C_toplevel(long int, long int, long int)’: That function is used in line 58 of the C++ file (I know line numbers in generated C++ could perhaps vary from my setup to others, but this is just to show the relative order of lines): type55 t56 = crunch_callback14(t54); but is only declared in line 76: C_externexport void crunch_callback14(int t0); And defined in line 135: void crunch_callback14(int t0){ ... } OK, so I manually added a declaration at the top of the file: C_externexport void crunch_callback14(int t0); and got this error: crunch-bug.cpp: In function ‘type37 f36(type35)’: crunch-bug.cpp:62: error: conversion from ‘void’ to non-scalar type ‘type55’ requested OK. It won't return anything, so I changed the function call from type55 t56 = crunch_callback14(t54); to: crunch_callback14(t54); (And verified that t56 is *not* referenced at all in the C++ code). And, HEY, it compiles!!! But the generated binary doesn't work: $ g++ crunch-bug.o -lchicken $ ./crunch-bug Error: unbound variable: r Call history: r <-- I suppose this is the r here, in line 60 of crunch.scm: (define-syntax (define-crunch-primitives x r c) But I wasn't able to debug further. |
