From d48b28418355ef41a9501eb28a82ec0b69e62a17 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Fri, 24 Sep 2010 20:00:52 +0000 Subject: perl: bump the required Perl version to 5.8 from 5.6.[21] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already used the three-arg form of open() which was introduced in 5.6.1, but t/t9700/test.pl explicitly depended on 5.6.2. However git-add--interactive.pl has been failing on the 5.6 line since it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open syntax: sub run_cmd_pipe { my $fh = undef; open($fh, '-|', @_) or die; return <$fh>; } Which when executed dies on "Can't use an undefined value as filehandle reference". Several of our tests also fail on 5.6 (even more when compiled with NO_PERL_MAKEMAKER=1): t2016-checkout-patch.sh t3904-stash-patch.sh t3701-add-interactive.sh t7105-reset-patch.sh t7501-commit.sh t9700-perl-git.sh Our code is bitrotting on 5.6 with no-one interested in fixing it, and pinning us to such an ancient release of Perl is keeping us from using useful features introduced in the 5.8 release. The 5.6 series is now over 10 years old, and the 5.6.2 maintenance release almost 7. 5.8 on the other hand is more than 8 years old. All the modern Unix-like operating systems have now upgraded to it or a later version, and 5.8 packages are available for old IRIX, AIX Solaris and Tru64 systems.

The -w sets warnings for all code that interpreter runs, while "use warnings" is lexically scoped. The former is probably not what the authors wanted. As an auxiliary benefit it's now possible to build Git with: PERL_PATH='/usr/bin/env perl' Which would previously result in failures, since "#!/usr/bin/env perl -w" doesn't work as a shebang.
