This is strange, when I test with simple data, for example:
(setq Lst '((4 5 6) (7 8 9)))
(println (eval> '+Agent 1 'setArticleWords (lit Lst)))
Then everything works just fine, the data is stored properly and I get
proper return values.
Then when I run the real code I just breaks down:
[import_feeds.l:7] !? (out Sock (pr (rest)))
5 -- Bad FD
?
If I then do for instance (pretty (rest)) there I get exactly the same
kind of list as in the simple test case, the only difference is that
it's much much longer. 5 is also the descriptor for the socket in both
cases.
My wrapper now looks like this:
(class +Agent)
(dm connect> (SockNum)
(connect "localhost" (+ 4040 SockNum)))
(dm sock> (A)
(let SockNum (if (num? A) A (max 1 (/ (; A aid) 10000)))
(or
(: sock)
(=3D: sock
(let Sock (connect> This SockNum)
(if Sock
Sock
(call "sh" "-c"
(pack "./p projects/rss-reader/word_index.l -go "
SockNum " -wait >> index.log 2>&1 &"))
(connect> This SockNum)))))))
(dm eval> (A . @)
(let? Sock (sock> This A)
(out Sock (pr (rest)))
(prog1 (in Sock (rd))
(close Sock))))
I've also tested tracing everything in the word index server and it
looks good, the data arrives and gets inserted and so on. So the FD
error seems to appear only after the index server actually returns the
results.
This I don't understand either as the error seems to imply that I'm
trying to open a socket that doesn't exist, which it does as it is
obviously receiving data and handling the data OK. The error only pops
up after the index server is done.
I hope I just missed something again here?
