Ok, your point very similar to answer above.
Probably my case limited to IPC communications then. It's pipes, localhost only.
I don't see reason to do non-blocking reads then. If data sending process is write whole message at once, say with
syswritefull($fh, sprintf("%08d", length($line))) && syswritefull($fh, $line)
it will be read by receiving process very fast (unless whole system unresponsive/swapping), and if sending process crashed/dies, there will be eof. Blocking pipes and reading whole message at once looks ok to me.
With blocking pipes you can still select() between them to determine which process sent you next message to read.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
