( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hmm... maybe this is a dumb-question, or an unnecessary one, but I do want to cover it just-in-case.   If the port-reader thread that is feeding data into Thread::Queue is terminated in this way, can we in fact be certain that the reader of that queue will in fact receive all of the data that has been sent?   Do we indeed have the means to be certain that every single byte that the client may have transmitted to the port will in fact be accounted-for, even if the final transmission is incomplete?   (I am thinking, not only of the bytes that have been posted into the queue, but also of any bytes that may have been queued-up in the read operation that we are about to shoot in the foot.)

“Just askin’ ...” ... but not entirely with an absence of motive or precedent.   Sometime in my distant past, a project that i was involved in was very seriously bitten by a manifestation of exactly this kind of issue.   Can we ... and I do not know this ... be c-e-r-t-a-i-n that this edge-case is covered?)

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.
