Thank you for posting this.

I have a question about the failed ithreads experiment though. I thought the biggest problems with ithreads were that:

  • They don't use native threads; the entire program is still a single process. (I don't understand the Windows threading model, but I'm pretty sure what I said is true on Unix-like platforms.)
  • There's still way too much global state in Perl 5.
  • Cloning an interpreter and the global state is hideously expensive.

Those all seem like implementation details, where the most important point of an ithreads model is default shared nothing -- which has tremendous advantages with regard to locking semantics.

What am I missing?

Update: audreyt and Liz are right; I read the threads source code, rather than grepping through the *.c files for Pthreads calls.

Title:
Use:  <p> text here (a paragraph) </p>

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.
