They can be close()d explicitly with close-file-descriptor, and will close() on gc, but only explicitly closing the last port on them will close the fileno. Notably needed for network sockets where we open separate input and output ports on the same socket.

** TODO native x86 backend
|
|
API redesign in preparation complete, initial
|
|
tests on native factorial and closures working.
|
|
** TODO fasl/image files
|
|
sexp_copy_context() can form the basis for images,
|
|
FASL for arbitrary modules will need additional
|
|
help with resolving external references.

*** TODO static image compiled into library

With this you'll be able to run Chibi without any filesystem.

|
*** TODO external tool to compact and optimize images
|
|
The current GC is mark&sweep, which can cause fragmentation,
|
|
but we can at at least compact the initial fixed image.
|
|
*** TODO fasl versions of modules
|
|
Important for large applications, and fast loading of script
|
|
with many dependencies.

This is important in particular for the output generated by

The current closure representation is not very efficient, so this

Being able to redefine procedures is important though.

|
|
Supported with UTF-8 strings, string-ref is O(n) and
|
|
string-set! may need to reallocate the whole string.
|
|
string-cursor-ref can be used for O(1) string access.

** DONE threads
|

- State "DONE" from "TODO" [2010-07-11 Sun 15:31]
|
|
VM now supports an optional hook for green threads,
|
|
and a SRFI-18 interface is provided as a separate module.
|
|
I/O operations will currently block all threads though,
|
|
this needs to be addressed.
