Bug 625576 – <sys-devel/autoconf-2.69 "autoheader" broken on perl without '.' in @INC ( fails test 38. tools.at:1278: testing autotools and whitespace in file names )

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Kent Fredric (IRC: kent\n) (RETIRED) 2017-07-18 23:38:58 UTC]

I swear I reported this earlier, but now I can't find the bug :/

Fortunately, autoheader doesn't appear to be used anywhere important, however, it is still broken by Perl 5.26 '.' removal from @INC ( it falls in the realm of "do" being broken, as per: https://wiki.gentoo.org/wiki/Project:Perl/Dot-In-INC-Removal#The_problem_with_do

This is exposed by a test failure that invokes autoheader, where autoheader has the problem code involving a chdiring into a tempdir, and then loading files from it assuming '.' in @INC, causing the test to fail.

Of course, as with bug #554748 , this is likely to affect all historical versions of autoconf, and all will need some solution applied ( or removal )

Output from test 038:

Seems like upstream noone cares.

Created attachment 487898 [details, diff]
patch fixing autoheader with Perl 5.26

Please review the attached patch. It makes the test suite pass with Perl 5.26.

    sys-devel/autoconf: Revbump to add another perl-5.26 fix (bug #625576).
    
    Package-Manager: Portage-2.3.6, Repoman-2.3.3


Keeping this bug open for possible fix of older autoconf versions. I only fixed autoconf-2.69

[Comment 4 Kent Fredric (IRC: kent\n) (RETIRED) 2018-09-09 03:55:22 UTC]

Just confirming this bug is still occurring in 2.64, which appears to be needed by GCC 8.

Really not interested in stabilizing perl 5.26 until this is put to bed.

    sys-devel/autoconf: Revision bump 2.64-r1 for Perl 5.26
    
    This fixes the Perl 5.26 - related failures.
    I observe one more failure (both with and without the patches)
    which may point at some other problem:
    221: Unusual Automake input files                    FAILED (torture.at:1517)

    sys-devel/autoconf: Revision bump 2.13-r1 for Perl 5.26
    
    Only one patch needed, the other one modifies code that does
    not exist in this version yet.
    
    Test suite passes in either case, not catching the problem.
