Perl: added PERL_SET_INTERP().
For Perl compiled with threads, without PERL_SET_INTERP() the PL_curinterp
remains set to the first interpreter created (that is, one created at
original start). As a result after a reload Perl thinks that operations
are done withing a thread, and, most notably, denies to change environment.
For example, the following code properly works on original start,
but fails after a reload:
perl 'sub {
my $r = shift;
$r->send_http_header("text/plain");
$ENV{TZ} = "UTC";
$r->print("tz: " . $ENV{TZ} . " (localtime " . (localtime()) . ")\n");
$ENV{TZ} = "Europe/Moscow";
$r->print("tz: " . $ENV{TZ} . " (localtime " . (localtime()) . ")\n");
return OK;
}';
To fix this, PERL_SET_INTERP() added anywhere where PERL_SET_CONTEXT()
was previously used.
Note that PERL_SET_INTERP() doesn't seem to be documented anywhere.
Yet it is used in some other software, and also seems to be the only
solution possible.
