Nonblocking sockets no longer raise a continuable exception when a

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

cygwin does not have getaddrinfo so I added a compatibility

implementation in src/ikarus-getaddrinfo.[ch]
2007-12-26 22:28:48 -05:00
4f0a816295
Added a tcp-connect procedure that takes a host name and a service
...
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.

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

2007-12-18 05:41:39 -05:00
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.
