See attached patch. This probably should go into 5.28 but I'm not 100%
sure because of timing and some risk of leaving out a symbol/CPAN
breakage, but I'll guess I'm the only person in the world who compiles
-DNO_MATHOMS since nobody else noticed the problem in 2 yrs, so if a
symbol is left out that shouldn't have been, oh well, the feature was
broken in the last stable anyway. Better than waiting a year. Backport
too since its been broken since 5.25.0-5.25.1.

Subject: [PATCH] fix -DNO_MATHOMS build, mathomed syms were not removed from
 perldll.def

Commit 3f1866a8f6 assumed "A" flag means a function can't be mathomed. Not
true. Many funcs were listed in embed.fnc as "A" yet were in mathoms.c.
This caused a missing symbol link failure on Win32 with -DNO_MATHOMS,
since the "A" mathomed funcs were now put into perlldll.def while
previously they were parsed out of mathoms.c by makedef.pl. Revise the
logic so "b" means instant removal from the export list on a no mathoms
build.

embed.fnc "b" flag adds were generated from a missing symbol list from my
linker, some funcs not in my build/platform config might need to be "b"
flagged in future. Some funcs like ASCII_TO_NEED were already marked "b"
but still being by mistake exported because they were also "A".

sv_2bool, sv_eq and sv_collxfrm also needed a "p" flag or a Perl_-less
symbol was declared in proto.h. sv_2bool and sv_collxfrm also failed
porting/args_assert.t so add those macros to mathoms.c

This is a bug report for perl from bulk88@​hotmail.com,
generated with the help of perlbug 1.41 running under perl 5.27.9.

-----------------------------------------------------------------
[Please describe your issue here]

See attached patch. This probably should go into 5.28 but I'm not 100%
sure because of timing and some risk of leaving out a symbol/CPAN
breakage, but I'll guess I'm the only person in the world who compiles
-DNO_MATHOMS since nobody else noticed the problem in 2 yrs, so if a
symbol is left out that shouldn't have been, oh well, the feature was
broken in the last stable anyway. Better than waiting a year. Backport
too since its been broken since 5.25.0-5.25.1.

See also
https://www.nntp.perl.org/group/perl.perl5.porters/2018/04/msg250381.html

My default mode of compiling is -DNO_MATHOMS, so that I would find any
breakage. But I just use the default options on Windows dromedary, so
wouldn't see it there.

AIX has long had warnings like this​:
ld​: 0711-319 WARNING​: Exported symbol not defined​: ASCII_TO_NEED

which I never thought was high enough priority to investigate. But this
ticket explains it.

I tried your patch on Linux, and surprisingly to me, it generated test
failures

# Failed test 1 in t/pv_tools.t at line 54
# Test 7 got​: "N\\375 Batter\\355" (t/pv_tools.t at line 64)

# Test 9 got​: "\\301g\\346tis Byrju..." (t/pv_tools.t at line 67)
# Expected​: "\\303\\201g\\303\\246t..."

which I haven't investigated.

First test failure,


void
pv_escape_can_unicode()
  PPCODE​:
#if defined(is_utf8_string) && defined(utf8_to_uvchr)
  XSRETURN_YES;
#else
  XSRETURN_NO;
#endif



my $uni = &Devel​::PPPort​::pv_escape_can_unicode();

# sanity check
ok($uni ? $] >= 5.006 : $] < 5.008);


Since CPP macro utf8_to_uvchr is now undefined because of -DNO_MATHOMS and embed.h, while before I think the macro was defined to the Perl_utf8_to_uvchr, but nothing ever in core referenced the C symbol so it all linked together even tho the func isn't defined anywhere.

So thats the first test fail.

utf8_to_uvchr was moved to mathoms.c in 5.21.1 https://perl5.git.perl.org/perl.git/commitdiff/f2645549e6a4bfca055b5fd1932da462df424921

utf8_to_uvchr was supposedly added in 5.7.1.

ppport uses utf8_to_uvchr as part of its pv_escape replacement https​://perl5.git.perl.org/perl.git/blob/5f6af817add6d2df3603e0e94b6eb27ba5fb3970​:/dist/Devel-PPPort/parts/inc/pv_tools#l74 but native pv_escape was added in 5.9.4 supposedly, so 5.21.1 and up that deprecated/removed utf8_to_uvchr() in -DNO_MATHOMS will never run into a link failure because they will always use native pv_escape and not the ppport.h fill in. The native pv_escape uses utf8_to_uvchr_buf() instead of utf8_to_uvchr() https​://perl5.git.perl.org/perl.git/blob/5f6af817add6d2df3603e0e94b6eb27ba5fb3970​:/dump.c#l166 since https://perl5.git.perl.org/perl.git/commitdiff/4b88fb76efce8c436e63b907c9842345d4fa77c7 in 5.15.9

If I add a ! op to dist/Devel-PPPort/t/pv_tools.t


my $uni = &Devel​::PPPort​::pv_escape_can_unicode();
$uni = ! $uni;

# sanity check
ok($uni ? $] >= 5.006 : $] < 5.008);


the rest of the tests pass.

So who is at fault? ppport or p5p for deprecating utf8_to_uvchr()?

We cud stick an

#ifndef utf8_to_uvchr
# define utf8_to_uvchr(a,b) Perl_utf8_to_uvchr(aTHX_ a,b)
#endif

to counteract

#ifndef NO_MATHOMS
#define utf8_to_uvchr(a,b) Perl_utf8_to_uvchr(aTHX_ a,b)
#endif

in the perl headers somewhere, or change

https://perl5.git.perl.org/perl.git/blob/5f6af817add6d2df3603e0e94b6eb27ba5fb3970:/dist/Devel-PPPort/parts/inc/pv_tools#l206


void
pv_escape_can_unicode()
  PPCODE​:
#if defined(is_utf8_string) && (defined(utf8_to_uvchr) || defined(utf8_to_uvchr_buf))
  XSRETURN_YES;
#else
  XSRETURN_NO;
#endif

From @khwilliamson

I think its best to add safety as far back as possible, so I would want to define utf8_to_uvchr_buf in ppport.h in terms of plain utf8_to_uvchr, as they differ mainly in that the _buf version has better malformation checking. But alas, I could not get ppport stuff to work. So doing that change has to be deferred.

So, in the meantime, I merely moved utf8_to_uvchr() away from mathoms.c, so it will always be defined. Commit 7723e00 did that.

Then the patch for this ticket works, and was pushed as
