I'm getting an error declaring a nihilic operator that has an index
parameter using ⎕FX:

When I declare it using the lambda format, the declaration works but trying
to call it gives an error. Trying to call it without the index parameter

Here's a patch that fixes the compilation error when disabling readline on
OSX (and possibly non-OSX as well?).

Hi Elias,
if have implemented the *poll() *as a non-default alternative to
*select() *in *APserver*.
Unfortunately I can't reproduce the problems that I had earlier (they
occurred in the middle
of development), but I would be surprised if*poll()* would differ
from*select() *in that respect.
Dear Elias,
A third column with that other information (uniqueness, null-ability, etc.)
would be useful.
Thanks!

Sorry, not POLLPRI. It's POLLERR or POLLHUP. You can see how it's done here:

I believe if you use poll() rather than select(), you should be able to
detect this state. Add a listener for the event POLLPRI.

Hi Elias,
given that hardly anybody uses shared variables these days this discussion
is more on the theoretical side than of practical relevance.
For that reason I would like the solution to be as simple as possible.
The extra things needed as you state below make things more complicated

I did not know about that feature. Interesting. Also interesting that it's
not supported on OSX.
That said, I still think Unix domain sockets are good in this case. There
are just a few things that needs to be done in order to make them solid. I
think I did most of those things in the native code
Hi Elias,
the idea is this:
man 7 unix says:
/abstract: an abstract socket address is distinguished by the fact//
// that sun_path[0] is a null byte ('\0'). The socket's
address in//
// this namespace is given by the additional bytes in sun_path
that are//
//
Ah, sorry. My question was about the "+ABSTRACT_OFFSET". That particular
addition of the value 1 to the sun_path field was what caused the failure.
What I wondered was what is the purpose of ABSTRACT_OFFSET?

Elias

Hi Elias,
Unix Domain Sockets were your proposal if I remember correctly :-) .
They caused a few extra problems, for example select() does not
notice when a connection is closed.
Not sure which call you mean?

I've added a function number 9 to the SQL library. This function takes the
name of a table and returns information about the columns in that table.
The function has no name in SQL.apl yet, because I am currently overseas

I agree with you. And that's what I intended to do (perhaps I made a
mistake in my code?)
The file in wslib5 should indeed be upper case. The file in the src/sql
directory is lower case. The installation that copies the file to wslib5
changes the name to make it uppercase.

Hi Elias,
I have lower-cased everything even though I would
argue that SQL, being an abbreviation, should be uppercase.
I have removed the stale files (they were only in SVN not in the
packages built).

You can't undef a typedef, but you can hack around it by #define Function
Something_Else, and then #undef Function after including the offending

That said, the C++ solution is to place your own definitions into a unique

thanks. I made some changes rot readline to be more portable.

It is really not nice to typedef a fundamental name like "Function" in a

The src/sql directory contains all files from my source repository, but it
