[RFC] Sync readline to version 6.3 patchlevel 8
This patch syncs our upstream copy of readline to version 6.3
patchlevel 8.
I basically copied what was done when Jan updated to readline 6.2 in
2011: http://sourceware.org/ml/gdb-patches/2011-05/msg00003.html
Specifically, I:
1. Extracted the readline 6.3 tarball on top of readline/
2. Applied patches 1-8 from ftp://ftp.cwru.edu/pub/bash/readline-6.3-patches/
3. Omitted all the files in doc/ that were intentionally omitted before.
4. Regenerated readline/configure and readline/examples/rlfe/configure
using autoconf 2.64. No other configure files needed regenerating.
5. Reapplied the only local patch since the update to readline 6.2 that
has not already been applied to readline 6.3, 05942d8a1 ("Fix
executable indicator in file name completeion on Windows."). This
particular patch has been applied upstream but readline 6.3 does not
have it. Whether or not a local patch has already been applied to
readline 6.3 was determined via manual inspection. (Wasn't too bad
really.)
The new files to make it into the tree are:
colors.{c,h}
configure.ac
parse-colors.{c,h}
examples/hist_erasedups.c
examples/hist_purgecmd.c
Deleted files:
configure.in
I've been using this patch locally for a few months now and I've
experienced only a single regression which has already been preemptively
fixed by 8900d71e3 ("Explicitly call rl_resize_terminal() in TUI's
SIGWINCH handler"). Other than that, no issues in either the CLI or the
TUI, or changes in the testsuite. Though I have only been able to test
this patch on Linux.
Have I missed anything? What else should be done in order to sync our
copy of readline? Unlike the last sync from 5.1 to 6.2, this sync to
6.3 is quite minor and hopefully painless.
Because the commit is so big and so mechanical I elected to create a
branch users/ppalka/readline-6.3-update where you can view/test the
change.
readline/ChangeLog.gdb:
Import readline 6.3 and upstream patches 1-8.
* configure: Regenerate.
* examples/rlfe/configure: Regenerate.
* complete.c: Reapply previous change.

The texinfo files include both user and programmer's manuals. HTML versions of the manuals appear in the `doc' subdirectory as well. +Usage +===== + +Our position on the use of Readline through a shared-library linking +mechanism is that there is no legal difference between shared-library +linking and static linking--either kind of linking combines various +modules into a single larger work. The conditions for using Readline +in a larger work are stated in section 3 of the GNU GPL. + Reporting Bugs ============== diff --git a/readline/aclocal.m4 b/readline/aclocal.m4 index 716a0436113..a947272e2ce 100644 --- a/readline/aclocal.m4 +++ b/readline/aclocal.m4 @@ -1698,7 +1698,6 @@ AC_CHECK_FUNC(mbscmp, AC_DEFINE(HAVE_MBSCMP)) AC_CHECK_FUNC(mbsnrtowcs, AC_DEFINE(HAVE_MBSNRTOWCS)) AC_CHECK_FUNC(mbsrtowcs, AC_DEFINE(HAVE_MBSRTOWCS)) - AC_REPLACE_FUNCS(mbschr) AC_CHECK_FUNC(wcrtomb, AC_DEFINE(HAVE_WCRTOMB)) @@ -1763,6 +1762,33 @@ if test $bash_cv_type_wint_t = yes; then AC_DEFINE(HAVE_WINT_T, 1, [systems should define this type here]) fi +dnl check for broken wcwidth +AC_CACHE_CHECK([for wcwidth broken with unicode combining characters], +bash_cv_wcwidth_broken, +[AC_TRY_RUN([ +#include <unistd.h> +#include <stdlib.h> +#include <stdio.h> + +#include <locale.h> +#include <wchar.h> + +main(c, v) +int c; +char **v; +{ + int w; + + setlocale(LC_ALL, "en_US.UTF-8"); + w = wcwidth (0x0301); + exit (w == 0); /* exit 0 if wcwidth broken */ +} +], +bash_cv_wcwidth_broken=yes, bash_cv_wcwdith_broken=no, bash_cv_wcwidth_broken=no)]) +if test "$bash_cv_wcwidth_broken" = yes; then + AC_DEFINE(WCWIDTH_BROKEN, 1, [wcwidth is usually not broken]) +fi + if test "$am_cv_func_iconv" = yes; then OLDLIBS="$LIBS" LIBS="$LIBS $LIBICONV" @@ -3098,7 +3124,7 @@ AC_DEFUN([AC_LIB_LINKFLAGS_BODY], found_so= found_a= if test $use_additional = yes; then - if test -n "$shlibext" && test -f "$additional_libdir/lib$name.$shlibext"; then + if test "X$prefer_shared" = "Xyes" && test -n "$shlibext" && test -f "$additional_libdir/lib$name.$shlibext"; then found_dir="$additional_libdir" found_so="$additional_libdir/lib$name.$shlibext" if test -f "$additional_libdir/lib$name.la"; then @@ -3120,7 +3146,7 @@ AC_DEFUN([AC_LIB_LINKFLAGS_BODY], case "$x" in -L*) dir=`echo "X$x" | sed -e 's/^X-L//'` - if test -n "$shlibext" && test -f "$dir/lib$name.$shlibext"; then + if test "X$prefer_shared" = "Xyes" && test -n "$shlibext" && test -f "$dir/lib$name.$shlibext"; then found_dir="$dir" found_so="$dir/lib$name.$shlibext" if test -f "$dir/lib$name.la"; then @@ -4123,7 +4149,7 @@ main() AC_DEFUN(BASH_STRUCT_WEXITSTATUS_OFFSET, [AC_MSG_CHECKING(for offset of exit status in return status from wait) AC_CACHE_VAL(bash_cv_wexitstatus_offset, -[AC_RUN_IFELSE([ +[AC_TRY_RUN([ #include <stdlib.h> #include <unistd.h> diff --git a/readline/bind.c b/readline/bind.c index a939528862f..8acf4ac4ca0 100644 --- a/readline/bind.c +++ b/readline/bind.c @@ -1,6 +1,6 @@ /* bind.c -- key binding and startup file support for the readline library. */ -/* Copyright (C) 1987-2010 Free Software Foundation, Inc. +/* Copyright (C) 1987-2012 Free Software Foundation, Inc.
