[cmucl-imp] Method combination woes
by Didier Verna 30 Jan '18

Hello! It seems that the 2018/02 snapshot of CMUCL doesn't properly handle method combination updating in generic functions: CL-USER> (define-method-combination my-min () ((methods ())) `(min ,@(mapcar #'(lambda (method) `(call-method ,method)) methods))) MY-MIN CL-USER> (define-method-combination my-max () ((methods ())) `(max ,@(mapcar #'(lambda (method) `(call-method ,method)) methods))) MY-MAX CL-USER> (test 0) 5 CL-USER> (reinitialize-instance #'test :method-combination (mop:find-method-combination #'make-instance 'my-max nil)) #<STANDARD-GENERIC-FUNCTION TEST (2) {4AB267B9}> CL-USER> (test 0) 5 Here, 6 was expected, not 5, and despite the fact that the method combination slot in the generic function object was correctly updated to MY-MAX. Besides, ENSURE-GENERIC-FUNCTION also seems to fail handling method-combination changes properly: (ensure-generic-function 'test :method-combination (mop:find-method-combination #'make-instance 'my-max nil)) Type-error in KERNEL::OBJECT-NOT-LIST-ERROR-HANDLER: #<Method-Combination MY-MAX NIL {49C2D605}> is not of type LIST [Condition of type TYPE-ERROR] Comments? -- Resistance is futile.

[cmucl-imp] Snapshot 2018-01
by Raymond Toy 15 Jan '18

15 Jan '18

The new year brings us a new snapshot for January. A few minor changes: * ASDF upgraded to 3.3.1 * A new random number generator where mt19937 is replaced by xoroshiro128+. This generator is faster than mt19937 and instead of some 600 words of state, only 4 are needed. The new generator requires a cross-compile using 21c/boot-21c-cross.lisp. Binaries will be uploaded soon. -- Ray
