In other words. IT WORKS!
No. It does not. It hangs. Unless you reconnect every messages (close socket after every message and make new connections for new messages).
that your code was exactly as vulnerable to the same issue -- an incomplete message, perpetual block -- as they are.
Ie. If you added that sleep in the same place in the client code, and ran it against your OP sysread() wrapper, it blocks in exactly the same way!
No. Your code hanged without printing "This is the last line". Mine would block in the same select, waiting new data (which will not come), but after printing "This is the last line".

No, but my code will block in case incomplete message (which will never happen, unless client is buggy), and your code hangs even in the middle of complete message: client sent complete message, but code read only half of it.

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 How to display code and escape characters are good places to start.
