Re: How do I get a unique Perl Interpreter ID?

prefer to stay in pure Perl if I possibly can.

AFAIK, outside of going into XS to create your own interpreter; thread == interpreter.

So, if you're staying in pure Perl -- and therefore not creating any Interpreters yourself explicitly; or implicitly other than via threads (& Windows fork emulation) -- then the combination of pid & tid should be unique.

Other than the possibility where the 32-bit tid wraps around, but if you're creating that many threads in a single process, then you could probably use the week number or maybe even month instead of the pid :)

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

As OP mentioned mod_perl under worker MPM I doubt that tid will work. Mod_perl creates its interpreters using `perl_clone`, without help of threads. Can't test at the moment though.	[reply] [d/l]
