This reverts commit b558ff043d.
This reverts commit 4a11f20659.
The initial import commit failed to retain local changes made to
readline's configure.in (and the commit message erroneously stated that
there were no local changes that needed to be reapplied). Also the
import caused a couple of build errors and a scattering of testsuite
regressions throughout many arches. It's probably better to start over
with this import, hopefully more carefully next time.
Since the sync to version 7.0-alpho, readline now by default builds
(unused) shared libraries alongside static libraries, whereas before it
only built static libraries. A couple of GDB buildbots were not happy
with this change:
http://gdb-build.sergiodj.net/builders/AIX-POWER7-plain/builds/240http://gdb-build.sergiodj.net/builders/Fedora-i686/builds/1518
To get these buildbots building again, this patch alters readline's
configure.ac file to not build shared libraries by default, as was the
case with readline 6.2. A more permanent fix may be to alter the
top-level Makefile.def to pass --disable-shared to readline, or to
investigate why these building these shared libraries are giving the
buildbots trouble. (I think the proximate reason why the i686 buildbot
fails is because it passes CFLAGS=-m32 instead of CC="gcc -m32" to the
top-level configure script, and readline's linker commands don't inherit
CFLAGS. Not sure about the AIX failure.)
readline/ChangeLog.gdb:
* configure.ac: Default opt_shared_libs to no.
* configure: Regenerate.
This patch syncs our upstream copy of readline from version 6.2 to the
latest version, 7.0 alpha (released July 10 2015).
I essentially copied what was done the last time readline was synced,
when Jan updated to readline 6.2 in 2011:
http://sourceware.org/ml/gdb-patches/2011-05/msg00003.html
Procedure:
1. I extracted the readline-7.0-alpha tarball on top of readline/.
2. I deleted all the new files under doc/ that were deliberately omitted
before.
3. I regenerated readline/configure and readline/examples/rlfe/configure
using autoconf 2.64. No other configure files need regenerating.
4. I updated the function gdb_printable_part in completer.c with a
trivial change made to the readline function it is based off of,
printable_part in readline/complete.c. There is more work to be done in
completer.c to sync it with readline/complete.c, but it is non-trivial
and should probably be done separately anyway.
Local patches that had to be reapplied:
None. readline 7.0 alpha contains all of our local readline
patches.
New files in readline/:
colors.{c,h}
examples/{hist_erasedups,hist_purgecmd,rl-callbacktest,rlbasic}.c
parse-colors.{c,h}
readline.pc.in
configure.ac
Deleted files in readline/:
configure.in
Regressions:
After the sync there is one testsuite regression, the test
"signal SIGINT" in gdb.gdb/selftest.exp which now FAILs. Previously,
the readline 6.2 SIGINT handler would temporarily reinstall the
underlying application's SIGINT handler and immediately re-raise SIGINT
so that the orginal handler gets invoked. But now (since readline 6.3)
its SIGINT handler does not re-raise SIGINT or directly invoke the
original handler; it now sets a flag marking that SIGINT was raised, and
waits until readline explicitly has control to call the application's
SIGINT handler. Anyway, because SIGINT is no longer re-raised from
within readline's SIGINT handler, doing "signal SIGINT" with a stopped
inferior gdb process will no longer resume and then immediately stop the
process (since there is no 2nd SIGINT to immediately catch). Instead,
the inferior gdb process will now just print "Quit" and continue to run.
So with this commit, this particular test case is adjusted to reflect
this change in behavior (we now have to send a 2nd SIGINT manually to
stop it).
Aside from this one testsuite regression, I personally noticed no
regression in user-visible behavior. Though I only tested on x86_64
and on i686 Debian Stretch.
Getting this kind of change in at the start of the GDB 7.11 development
cycle will allow us to get a lot of passive testing from developers and
from bleeding-edge users.
readline/ChangeLog.gdb:
Import readline 7.0 alpha
* configure: Regenerate.
* examples/rlfe/configure: Regenerate.
gdb/ChangeLog:
* completer.c (gdb_printable_part): Sync with readline function
it is based off of.
gdb/testsuite/ChangeLog:
* gdb.gdb/selftest.exp (test_with_self): Update test to now
expect the GDB inferior to no longer immediately stop after
being resumed with "signal SIGINT".
* complete.c (stat_char) [_WIN32]: Don't use 'access' and X_OK on
Windows, they don't work. Instead, look at the file-name
extension to determine whether the file is executable.

Merge in official patches to readline-4.3 from
ftp://ftp.cwru.edu/pub/bash/readline-4.3-patches:
NOTE: Patch-ID readline-43-004 was already applied (see below).
* bind.c (rl_generic_bind): Pressing certain key sequences
causes an infinite loop in _rl_dispatch_subseq with the `key' argument
set to 256. This eventually causes bash to exceed the stack size
limit and crash with a segmentation violation.
Patch-ID: readline43-001.
* readline.c (_rl_dispatch_subseq): Repeating an edit in
vi-mode with `.' does not work.
Patch-ID: readline43-002.
* mbutil.c (_rl_get_char_len, _rl_compare_chars,
_rl_adjust_point): When in a locale with multibyte characters, the
readline display updater will occasionally cause a
segmentation fault when attempting to compute the length of the first
multibyte character on the line.
Patch-ID: readline43-003.
* vi_mode.c (_rl_vi_change_mbchar_case): Using the vi editing
mode's case-changing commands in a locale with multibyte characters
will cause garbage characters to be inserted into the editing buffer.
Patch-ID: readline43-005.

screen width and height using console I/O.
(_rl_init_terminal_io) [__MSDOS__]: Zero out all the _rl_term_*
variables. Convert to _rl_* naming scheme.
(_rl_set_cursor) [__MSDOS__]: Ifdef away this function.
* display.c (_rl_move_vert) [__MSDOS__]: Don't use undeclared

Assign -delta to i instead of the other way around.
* rlmbutil.h: Require HAVE_MBSTATE_T for HANDLE_MULTIBYTE.
Revert requirement of HAVE_MBRTOWC. Delete macro definitions
that attempted to fake mbstate_t if HAVE_MBSRTOCWS is defined
and HAVE_MBSTATE_T is not defined.
