It also provides the ability to spell the equals sign as a +double equals. This does nothing whatsoever -- it adds no new +functionality to bash, it forbids nothing, it is *literally* an exact +alias. + +It should never be used under any circumstances. All developers must +immediately forget that it exists. Using it is non-portable and does not +work in /bin/sh scripts such as configure scripts, and it results in +dangerous muscle memory when used in bash scripts because it makes +people unthinkingly use the double equals even in /bin/sh scripts. To +add insult to injury, it makes scripts take up more disk space (by a +whole byte! and sometimes even a few bytes...) + +Delete this accidental bashism, and restore the ability to get correct +./configure behavior on systems where /bin/sh is something other than a +symlink to GNU bash. + +Signed-off-by: Eli Schwartz <eschwartz93@gmail.com> +--- + configure.ac | 8 ++++---- + 1 file changed, 4 insertions(+), 4 deletions(-) + +diff --git a/configure.ac b/configure.ac +index c0ac33c..619e162 100644 +--- a/configure.ac ++++ b/configure.ac +@@ -44,7 +44,7 @@ AC_ARG_ENABLE(debug, + [ --enable-debug Turn on debug compiler information], + [ENABLE_DEBUG_FLAG="$enableval"], + [ENABLE_DEBUG_FLAG="yes"]) +-if [[ "x$ENABLE_DEBUG_FLAG" == "xyes" ]] ; then ++if test "$ENABLE_DEBUG_FLAG" = yes ; then + CXXFLAGS=${CXXFLAGS}" -g " + fi + +@@ -63,7 +63,7 @@ dnl AM_LDFLAGS=" -lm " + dnl if the debug flags are on, check if we can also use + dnl some profiling tools + dnl COMMENTED: Pass LDFLAGS to configure instead +-dnl if [[ "x$ENABLE_DEBUG_FLAG" == "xyes" ]] ; then ++dnl if test "$ENABLE_DEBUG_FLAG" = yes ; then + dnl AC_CHECK_LIB(profiler, google_initializer_module_profiler) + dnl AC_CHECK_LIB(pthread, pthread_create) + dnl AC_CHECK_LIB(tcmalloc, malloc) +@@ -81,11 +81,11 @@ CXXFLAGS="$CXXFLAGS -Werror=deprecated-declarations" + AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[#include <memory>]],[[int *a= new int(1); std::auto_ptr<int> b; b.reset(a);]])], + [ac_compilation_deprecated="no"],[ac_compilation_deprecated="yes"]) + AC_MSG_RESULT([$ac_compilation_deprecated]) +-if [[ "$ac_compilation_deprecated" == "yes" ]] ; then ++if test "$ac_compilation_deprecated" = yes ; then + AC_MSG_CHECKING([[if $CXX $CXXFLAGS supports atd::unique_ptr]]) + AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[#include <memory>]],[[int *a= new int(1); std::unique_ptr<int> b; b.reset(a);]])], + [ac_supports_unique_ptr="yes"],[as_supports_unique_ptr="no"]) +- if [[ "$ac_supports_unique_ptr" == "yes" ]] ; then ++ if test "$ac_supports_unique_ptr" = "yes" ; then + AC_DEFINE(USES_UNIQUE_PTR_AS_AUTO_PTR, [], [use unique_ptr instead of auto_ptr]) + fi + AC_MSG_RESULT([$ac_supports_unique_ptr]) +-- +2.43.0 + |
