[commit+] update-webkit-auxiliary-libs, update-webkit-support-libs cause Perl warnings about functions tmpnam and tmpfile

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Daniel Bates]

Perl complains about the functions tmpfile and tmpnam since they are defined in both File::Temp and POSIX. Script that run Perl with warnings enabled (-w flag) show these warnings, such as update-webkit-auxiliary-libs and update-webkit-support-libs.

Reduction

A simple example.

When you run this script, say: perl reduction.pl

You should see the following warnings:

Subroutine main::tmpfile redefined at /System/Library/Perl/5.8.8/Exporter.pm line 65.
 at /System/Library/Perl/5.8.8/darwin-thread-multi-2level/POSIX.pm line 19
Subroutine main::tmpnam redefined at /System/Library/Perl/5.8.8/Exporter.pm line 65.
 at /System/Library/Perl/5.8.8/darwin-thread-multi-2level/POSIX.pm line 19

perldoc -f use
says:

               If you do not want to call the package's "import" method (for
               instance, to stop your namespace from being altered), explic-
               itly supply the empty list:

                   use Module ();

               That is exactly equivalent to

                   BEGIN { require Module }


Looks fine.

You might want to add more information to the ChangeLog about why this stops the warning.
