From 234e3805c524a7432caed8be328df6e2fbfe9afb Mon Sep 17 00:00:00 2001 From: Russ Allbery Date: Wed, 27 Feb 2013 14:25:37 -0800 Subject: Update to rra-c-util 4.8 and C TAP Harness 1.12 Update to rra-c-util 4.8: * Look for krb5-config in /usr/kerberos/bin after the user's PATH. * Kerberos library probing fixes without transitive shared libraries. * Fix Autoconf warnings when probing for AIX's bundled Kerberos. * Avoid using krb5-config if --with-{krb5,gssapi}-{include,lib} given. * Correctly remove -I/usr/include from Kerberos and GSS-API flags. * Build on systems where krb5/krb5.h exists but krb5.h does not. * Pass --deps to krb5-config unless --enable-reduced-depends was used. * Do not use krb5-config results unless gssapi is supported. * Fix probing for Heimdal's libroken to work with older versions. * Update warning flags for GCC 4.6.1. * Update utility library and test suite for newer GCC warnings. * Fix broken GCC attribute markers causing compilation problems. * Suppress warnings on compilers that support gcc's __attribute__. * Add notices to all files copied over from rra-c-util. * Fix warnings when reporting memory allocation failure in messages.c. * Fix message utility library compiler warnings on 64-bit systems. * Include strings.h for additional POSIX functions where found. * Use an atexit handler to clean up after Kerberos tests. * Kerberos test configuration now goes in tests/config. * The principal of the test keytab is determined automatically. * Simplify the test suite calls for Kerberos and remctl tests. * Check for a missing ssize_t. * Improve the xstrndup utility function. * Checked asprintf variants are now void functions and cannot fail. * Fix use of long long in portable/mkstemp.c. * Fix test suite portability to Solaris. * Substantial improvements to the POD syntax and spelling checks. Update to C TAP Harness 1.12: * Fix compliation of runtests with more aggressive warnings. * Add a more complete usage message and a -h command-line flag. * Flush stderr before printing output from tests. * Better handle running shell tests without BUILD and SOURCE set. * Fix runtests to honor -s even if BUILD and -b aren't given. * runtests now frees all allocated resources on exit. * Only use feature-test macros when requested or built with gcc -ansi. * Drop is_double from the C TAP library to avoid requiring -lm. * Avoid using local in the shell libtap.sh library. * Suppress warnings on compilers that support gcc's __attribute__.
