Abdulaziz Ghuloum 8f0f0abbca Applied a patch supplied by Derick Eddington that provides enhanced
functionality for waitpid (nonblocking waitpid and more status info)

  (kill pid 'HUP).

top-marked wrapped syntax objects were incorrectly combined.

  (syntax-case (datum->syntax #'foo #'(x y)) ()
    [(x y) 'shouldntmatch] [_ 'ok])

yields shouldntmatch; it's now ok.

Abdulaziz Ghuloum d49aed209a Added (interaction-environment). 2008-05-01 06:02:36 -04:00
Abdulaziz Ghuloum e7386cd7d7 Major changes to the interactive repl:
- We can now redefine imported identifiers.
- We can now use let-syntax, letrec-syntax, and modules at
  top-level.

Hand-wavey Repl Semantics:
- Imported identifiers mean what they meant previously.  In
  particular, you cannot set! imported identifiers.
- An imported identifier may be redefined using define.  Once
  something is defined at the top-level, a specific location for it
  is created, and all definitions, references, and set!s to that
  variable go through the top-level location.
- Re-importing an identifier shadows the top-level location.
- Redefining re-exposes the top-level location.
- and do on.
- A reference to an unbound variable also fabricates a top-level
  location for that variable.

Let's see how this goes.
2008-05-01 04:21:07 -04:00

2008-04-28 14:01:49 -04:00
Abdulaziz Ghuloum 3ce6d037e4 Fixed a bug in module imports where some marks were missing in action.

    (syntax-rules ()
      [(_ m v) (let () (import m) v)]))
  (module a (x) (define x 'x-of-a))
  (from a x))

Didn't work before this change:

(let ()
  (define-syntax x-from-a
    (syntax-rules ()
      [(_) (let () (import a) x)]))
  (module a (x) (define x 'x-of-a))

      file-name: *stdin*
      character: 7

unregisters any callbacks associated with the buffer.

   mixed order)
2008-04-06 10:57:56 -04:00
Abdulaziz Ghuloum afd7592ae1 Added &i/o-read, &i/o-write, and &i/o conditions to read/write

and dispatches the appropriate callback.

2008-01-12 17:32:43 -05:00
Abdulaziz Ghuloum 7a2ac14f5a Eliminated frame-pointer adjustment around calls if the adjustment

Abdulaziz Ghuloum 64dac92831 Added tcp-connect-nonblocking which is line tcp-connect but puts the
socket in nonblocking mode.  An operation that would block now
raises (continuable) a condition of type &i/o-would-block which
contains the port in question.  There's no way to handle the
condition gracefully yet.
2007-12-27 22:08:27 -05:00

name (e.g. "www.google.com" and "http") and returns two binary ports:
the first for output and the second for input.
Both ports must be closed for the connection to close.

Also added an example in lab/tcp-connect-example.ss which connects 
to an http server, sends "GET /\n" and prints the responde.
2007-12-26 17:35:58 -05:00

syntax-violation for better syntactic error reporting.
2007-12-19 23:42:27 -05:00
Abdulaziz Ghuloum 6eb6bf750d Added a (process "cmd" "args" ...) procedure that execs cmd, passing
args to it, and returns 4 values: 
* the process's pid
* the process's standard-input-port  (for writing)
* the process's standard-output-port (for reading)
* the process's standard-error-port  (for reading)
See lab/process-example.ss for a sample usage.
2007-12-19 22:46:07 -05:00
Abdulaziz Ghuloum 10077a6468 minor change to the value returned by input-port-byte-position
(it's up by 1 now).

Abdulaziz Ghuloum 372c3e369b Change of strategy in the garbage collector.
Previously: when a generation (say 2) is collected, 
  everything in gen 0 moves to gen 1
  everything in gen 1 moves to gen 2
  everything in gen 2 moves to gen 3

Now: when a generation (say 2 again) is collected
  everything in gen 0 moves to gen 3
  everything in gen 1 moves to gen 3
  everything in gen 2 moves to gen 3

So, some objects get a leap from young to old if they're lucky to be
in the right time.

Consequences: when an object is moved by the collector, we don't
need to track old->new pointers and masks because all moved objects
are clean now.  This both simplifies the collector and makes it more
efficient and might open the door for further optimization
opportunities.  For bootstrap time, we get about 5% overall 
saving and about 20% GC-time saving.  Not bad.
