[armedbear-ticket] [armedbear] #65: UTF-32 strings support
by armedbear 11 Mar '13

#65: UTF-32 strings support ------------------------+--------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Component: other | Version: Keywords: | ------------------------+--------------------------------------------------- ABCL uses Java char[]s to represent its strings. However, the char type can only represent values in the BMP (Basic Multilingual Plane), because only the BMP can be represented using 16 bits. For supplementary characters (all Unicode chars outside the BMP), it uses a pair of surrogate characters (UTF-16). Common Lisp programs don't expect this and need strings to be represented using complete characters. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/65> armedbear <http://common-lisp.net/project/armedbear> armedbear

#113: DEFSTRUCT redefinition can crash ABCL on MAKE-FOO ---------------------+------------------------------------------------------ Reporter: mseddon | Owner: nobody Type: defect | Status: new Priority: minor | Milestone: Component: java | Version: Keywords: | ---------------------+------------------------------------------------------ CL-USER(1): (defstruct foo x y) FOO CL-USER(2): (defstruct foo x y z) FOO CL-USER(3): (make-foo :x 1 :y 2 :z 3) ABCL Debug.assertTrue() assertion failed! java.lang.Error: ABCL Debug.assertTrue() assertion failed! at org.armedbear.lisp.Debug.assertTrue(Debug.java:46) at org.armedbear.lisp.StructureObject.writeToString(StructureObject.java :483) Multiple DEFSTRUCTs do not change the underlying structure class, but seem to cause StructureObject to assert if the new (almost ignored) definition had a different number of slots than the old. For example, while the above example crashes out ABCL, the following example does not: CL-USER(1): (defstruct foo a b c) FOO CL-USER(2): (defstruct foo x y z) FOO CL-USER(3): (make-foo :x 1 :y 2 :z 3) #S(FOO :A 1 :B 2 :C 3) -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/113> armedbear <http://common-lisp.net/project/armedbear> armedbear

#73: "normalize-type" buffering -------------------------+-------------------------------------------------- Reporter: ehuelsmann | Owner: somebody Type: task | Status: new Priority: major | Milestone: Component: CLOS | Version: Keywords: performance | -------------------------+-------------------------------------------------- Peter Graves points out that with his "canonicalize-type" buffering, he achieved measurable performance gain in XCL. We want to do the same in ABCL. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/73> armedbear <http://common-lisp.net/project/armedbear> armedbear

#60: Implement USE-FAST-CALLS properly -------------------------+-------------------------------------------------- Reporter: trittweiler | Owner: ehuelsmann Type: defect | Status: new Priority: minor | Milestone: Component: compiler | Version: Keywords: | -------------------------+-------------------------------------------------- USE-FAST-CALLS is implemented at the moment by flipping an essentially global variable. The proper implementation would be to make turn it into a ABCL-specific declaration, and making sure it affects its lexically enclosing code only. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/60> armedbear <http://common-lisp.net/project/armedbear> armedbear

[armedbear-ticket] [armedbear] #32: Modify the currently disabled runtime-class.lisp code to not require ASM

#32: Modify the currently disabled runtime-class.lisp code to not require ASM --------------------------------------------------------------------+------- Reporter: vvoutilainen | Owner: somebody Type: enhancement | Status: new Priority: major | Milestone: Component: component1 | Version: Keywords: jvm bytecode compiler runtime dynamic class generation | --------------------------------------------------------------------+------- It's possible to define classes at runtime, by generating bytecode and loading it from the generated binary data, without ever writing it to a temporary file. runtime-class.lisp does that, but it requires an external bytecode library (ASM). ABCL has all the functionality for this to be done without ASM, so the task is to modify the runtime-class.lisp code so that ASM is no longer required and the code can be taken to be part of the build. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/32> armedbear <http://common-lisp.net/project/armedbear> armedbear

#30: Lisp debugger, for both compiled and interpreted code ----------------------------+----------------------------------------------- Reporter: vvoutilainen | Owner: somebody Type: enhancement | Status: new Priority: major | Milestone: unscheduled Component: component1 | Version: Keywords: debug debugger | ----------------------------+----------------------------------------------- ABCL code can be debugged with normal java debuggers, but it is somewhat painful for the portions implemented in lisp(1). So we need a lisp debugger. (1) It's possible, although a bit tedious, to step through eval calls in a java debugger by examining the cars and cdrs of eval parameters when stepping the code. -- Ticket URL: <http://127.0.0.1:8000/armedbear/ticket/30> armedbear <http://common-lisp.net/project/armedbear> armedbear
