Applied a patch supplied by Derick Eddington that provides enhanced
...
functionality for waitpid (nonblocking waitpid and more status info)
as well as the ability to send a signal to a process, e.g.,
(kill pid 'HUP).

Changes from Derick Eddington supporting file system info:
...
- Added file-regular?, file-directory?, file-symbolic-link?,
directory-list, make-directory, delete-directory, change-mode,
and make-symbolic-link.
- Bug fix in ikrt_open_input_fd and ikrt_open_output_fd which
considered a 0 FD as an error.
- Bug fix in ikrt_getcwd about len+1.
- Bug fix of &i/o-file-protection which didn't have &i/o-filename as
its parent.
- There is a new src/ikarus-errno.c file.
- Made tcp-connect and friends tell when they "failed to resolve
host name or connect".
- To support the uses of &i/o-filename subtypes, I modified
print-condition so it will cleanly print the parents' fields of a
condition;

4acf71d6d2
moved pretty-printing formats to their own library.
2008-05-12 00:35:19 -07:00
f05f171f28
exported pretty-format, a parameter maker for setting the pretty
...
format for various forms. The pretty format structure is not
documented yet and there is no error-checking mechanism for
verifying proper input.

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

Added process-nonblocking which is like process but returns
...
nonblocking ports.

- Added reset-output-port! which sets the write index to 0 and
...
unregisters any callbacks associated with the buffer.
- commented out the call for unblocking the stdin for now
(for reason yet unknown to me, it causes stdout to be unblocked
as well, making writes to the console to come out in bizarre
mixed order)
2008-04-06 10:57:56 -04:00
884f3fe921
Added tcp-server-socket-nonblocking, tcp-accept-connection-nonblocking

Added a tcp-connect-nonblocking-example.ss to demonstrate how to
...
handle nonblocking sockets by continuous polling.
2007-12-27 22:17:54 -05:00
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.
