unchecked FD_SETSIZE in fdset operations

Hi,

code in libsys.scm and port.c uses FD_SET, FD_ISSET and friends on 
fdset. It however doesn't check if the descriptor in question is 
smaller then FD_SETSIZE. This in my case results in a segfault of 
the interpreter. I'm not including the fixing patch because the fix 
is rather trivial.

Best regards,
Tomas Stanek

You're right.  Fix is coming.

Alternatively, one can allocate larger fd_set dynamically if given file
descriptor doesn't fit in FD_SETSIZE.  I guess it works on recent
systems.

Since it donesn't work on some system (e.g., I've heard that BSD earlier
than 4.4 silently ignores), working system should be white listed if
such strategy is taken.

# Of course an interface for another syscall such as poll would be
# better.

Yeah,
I'm an old-school Unix guy and select(2) was in my toolbox for long time.
That's why sys-select was in Gauche from very early stage.  However
these days it feels rather archaic.   Also the model of select(2)
can't be easiliy emulated on Windows.

I'd like to have event-callback type of API, but unfortunately each
system provides slightly different models.  Using exsiting libraries
to abstract the differences may be an option...

DBI example

First: is this the right mailing list for user questions?

If so:

I tried the DBI example from the reference documentation and get the
following error:

*** ERROR: list required, but got #<<mysql-result-set> 0x9b69fa0>

After some further reading I found the collection framework.

For newbies like me it would be useful to add the use statements at
the top of the example:

(use dbi)
(use gauche.collection)

Re: DBI example

Yes, you're welcome to post questions here.

And thanks for pointing it out.  I'll reflect it to the doc.
