Undefined subroutine &attributes::reftype >= 5.15.3 (XSLoader::load_file problem) #260

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
pcc -O3 -e'sub FETCH_SCALAR_ATTRIBUTES {''} sub MODIFY_SCALAR_ATTRIBUTES {''}; 
my $a :x=1; print $a'

Undefined subroutine &attributes::reftype called at 
/usr/local/lib/perl5/5.18.1/darwin-debug/attributes.pm line 57.

That's the simpliest attribute example. Note: works fine with our.

    bump version to 5.15.3 using Porting/bump-perl-version

but I have no idea why it started failing with this.
with --staticxs this commit passes

Now I know why: 
B::C starts using the internal XSLoader::load_file function starting with 5.15.3
# 5.15.3 workaround [perl #101336], without .bs support
# XSLoader::load_file($module, $modlibname, ...)

--staticxs bypasses this function.

    C major change: skip redefinition of internal XS CVs

    Internal XS xsubs are already booted in the perl_parse step.
    When we encounter them we set new GPs for those, which was a problem on Windows
    where we cannot declare and boot the said XS functions (not exported).
    We rather keep the old GV, GP and CV.

Fixed with 1.42_66

    C 1.42_66: fix XSLoader::load_file

    use proper dlext string append. fixes most 5.16,5.18 XS tests
    add more DynaLoader::dl_debug output (set PERL_DL_DEBUG=1)
    Simplify xs stub definitions to one-liners with SvREFCNT_inc_simple_NN()
    remove DynaLoader from static_in_core list, needs to be booted explicitly.
    support user-defined static_ext modules (add themm to static_in_core)
