Fedora Project

  • Updated milter-greylist to 4.5.11 in Rawhide and EPEL-7:

    • Use asynchronous LDAP calls to reduce lock contention on heavy load

  • After building successfully and running it on my F-20 server, I was somewhat surprised to find that the build failed for Rawhide. The reason for this turned out to be that the project's configure script runs with -Werror enabled to turn warnings into errors, and the latest version of glibc in Rawhide spits out a warning about the _BSD_SOURCE symbol being deprecated in favour of _DEFAULT_SOURCE, which caused the check for res_ninit (thread-safe resolver) to fail. I worked around it with this patch: 

  • Warning about _BSD_SOURCE being deprecated in favor of _DEFAULT_SOURCE
breaks build with -Werror -Wall

  • However, it's not suitable for upstream as it breaks builds with older versions of gcc that don't understand the pragma.

  • Updated perl-Software-License to 0.103009 in Rawhide:

    • Updated FSF mailing address in license text for GFDL version 1.2, GPL versions 1 and 2, and LGPL 2.1

Local Packages

  • Updated perl-Mixin-Linewise to 0.105:

    • Update Readers to, by default, use PerlIO::utf8_strict to avoid problems with CRLF layer on Win32

  • Updated perl-Module-Load to 0.32:

    • Fix tests to support statically built perls

  • New package perl-PerlIO-utf8_strict (0.004)

  • Updated perl-Software-License to 0.103009 as per the Fedora version
