Re: Too many file descriptors

[Henrik Sarvell]

That went too fast, it can't work the way I suggested, below works and is
tested:

(dm rssToPages> @
   (let (Str (or (next) (exclient~call (; This rssLink) "" 5)) Fd (pipe
(prin Str)))
  (for A (rss~parseFrom Fd)
 (let Url
(req!> '+Url
   'link (a; A 'htmlUrl)
   'title (a; A 'title)
   'site This
   'pubAt (dtp~utcToStamp (a; A 'pubDate)) )
(linkUrl> '+SiteTag Url This) ) )
  (close Fd)) )

Re: Too many file descriptors

Thanks Alex,

I've changed the look to your #1 suggestion now:

(dm rssToPages> @
   (let Str (or (next) (exclient~call (; This rssLink) "" 5))
  (for A (rss~parseFrom
(pipe
   (prin Str)
   (let Url
  (req!> '+Url
 'link (a; A 'htmlUrl)
 'title (a; A 'title)
 'site This
 'pubAt (dtp~utcToStamp (a; A 'pubDate)) )
  (linkUrl> '+SiteTag Url This) ) ) ) ) ) )

Should work right?

(pipe (prin Str))) is probably the culprit.

'pipe' has two forms of invocation:
1. (pipe exe . prg) executes 'prg', and cleans up everything (wait for child and
   close the open file).
2. (pipe exe) returns a file descriptor, to be used subsequently. So you need to
   remember it, and close it when done.
