language is not being called when you wish it were.
I have to let Julia know it can reclaim memory about no longer referenced
variables. And I want to use the CCL GC to let me know when it is GCing the
memory related to some no longer bound variables. But it is the CCL:
terminate method that allows that. There are some other CL implementations,
at least SBCL, where I can give it directy a lambda form in such a way it
does my job:
(let ((ret (make-instance 'jlref :id id
:type (|jl_string_eval_string|
(concatenate 'string "string(typeof(getindex(refs,\=
"
" id "\")))")))))
#+:sbcl (sb-ext:finalize ret (lambda ()
(sb-concurrency:enqueue index *jqueue*))) ret)
Here is a sample session with SBCL,
)juliad is a system command that display the output of the command executed
in Julia
)julia execute a command in Julia,
)lisp same thing but in CL subsystem
refs the indexed dictionary in Julia
*jqueue* a FIFO queue populated by the CL terminate command. Since Julia
does not support multiple thread access through its library libjulia.so it
is up to the main FriCAS (CL) thread to delete entries in Julia 'refs', so
on user input,I check if some entries can be deleted in Julia, if so, I
delete them. Notice, there is a code helper here, a printf in the C
wrapper.
