2019-08-13[readline] Fix compilation on MinGWChristian Biesinger2-1/+6
S_ISLNK should not be called outside of an #ifdef. However, this specific call is actually unnecessary, because linkok can only be 0 if S_ISLNK is true, per the code above. I have sent a bug report to bug-readline, though it does not show up in the online archive yet. 2019-08-13 Christian Biesinger <cbiesinger@google.com> * colors.c (_rl_print_color_indicator): Remove unnecessary S_ISLNK check to fix compilation on MinGW.

2019-08-12Remove gdb workaround from readline/xfree.cTom Tromey4-11/+7
There is a gdb-local patch to deal with interrupts during completion. The original thread adding this patch is here: https://sourceware.org/ml/gdb-patches/2011-06/msg00147.html I believe readline now implements the approach suggested by Chet Ramey: https://sourceware.org/ml/gdb-patches/2011-06/msg00493.html So, I believe this patch can be removed. readline/ChangeLog.gdb 2018-10-07 Tom Tromey <tom@tromey.com> * Makefile.in (xfree.o): Don't depend on readline.h. * xfree.c (xfree): Remove gdb workaround. * xmalloc.h (xfree): Remove #define.
2019-08-12Remove gdb workaround from readline/emacs_keymap.cTom Tromey2-6/+4
There is a gdb-local patch in readline/emacs_keymap.c that says: /* Temporary - this is a bug in readline 5.1 that should be fixed in readline 5.2. */ So, I think this can be removed now. I have no way to test this, as the patch was specific to mingw. readline/ChangeLog.gdb 2018-10-07 Tom Tromey <tom@tromey.com> * emacs_keymap.c: Remove gdb workaround.
2019-08-12Remove gdb workaround from readline/complete.cTom Tromey2-5/+4
This removes a gdb-local patch from readline's get_y_or_n. The code references a gdb test that continues to work when I remove this patch. So, I think it is not needed any more. readline/ChangeLog.gdb 2018-10-07 Tom Tromey <tom@tromey.com> * complete.c (get_y_or_n): Remove gdb workaround.
2019-08-12Import readline 7.0 (patch 5)Tom Tromey96-1785/+9062
This imports readline 7.0 (up to patch 5) while preserving all gdb-local changes. This was done by checking out the readline git repository, making a branch based on the gdb baseline revision, applying the gdb changes to that branch, and then merging from readline 7. readline/ChangeLog.gdb 2019-08-12 Tom Tromey <tom@tromey.com> * Imported readline 7.0 patch 5.

Cleanup the readline warnings that gdb buildbot complains about. To prevent wcwidth missing declaration warnings, add the SOURCE / EXTENSION macros to config.in that have already checked for in configure. Ensure pid is a long before printing as one. Also fix GNU style. Check the return value of write the same way as history_do_write (). These changes are consistent with upstream readline. readline/ChangeLog.gdb: * config.h.in: Add SOURCE/EXTENSION macros. * histfile.c (history_truncate_file): Check return of write. * util.c (_rl_tropen): Ensure pid is long.
2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi2-3110/+2150
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL. Problem 2 (in zlib/): Makefile.am: error: required file './INSTALL' not found Makefile.am: 'automake --add-missing' can install 'INSTALL' Makefile.am: error: required file './NEWS' not found Makefile.am: error: required file './AUTHORS' not found Makefile.am: error: required file './COPYING' not found Makefile.am: 'automake --add-missing' can install 'COPYING' Solution 2: Add the foreign option to AUTOMAKE_OPTIONS. Problem 3: doc/Makefile.am:20: error: support for Cygnus-style trees has been removed Solution 3: Remove the cygnus options. Problem 4: Makefile.am:656: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS') Solution 4: Rename "INCLUDES = " to "AM_CPPFLAGS += " (because AM_CPPFLAGS is already defined earlier). Problem 5: doc/Makefile.am:71: warning: suffix '.texinfo' for Texinfo files is discouraged; use '.texi' instead doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 5: Rename .texinfo files to .texi. Problem 6: doc/Makefile.am: warning: Oops! doc/Makefile.am: It appears this file (or files included by it) are triggering doc/Makefile.am: an undocumented, soon-to-be-removed automake hack. doc/Makefile.am: Future automake versions will no longer place in the builddir doc/Makefile.am: (rather than in the srcdir) the generated '.info' files that doc/Makefile.am: appear to be cleaned, by e.g. being listed in CLEANFILES or doc/Makefile.am: DISTCLEANFILES. doc/Makefile.am: If you want your '.info' files to be placed in the builddir doc/Makefile.am: rather than in the srcdir, you have to use the shiny new doc/Makefile.am: 'info-in-builddir' automake option. Solution 6: Remove the hack at the bottom of doc/Makefile.am and use the info-in-builddir automake option. Problem 7: doc/Makefile.am:35: error: required file '../texinfo.tex' not found doc/Makefile.am:35: 'automake --add-missing' can install 'texinfo.tex' Solution 7: Use the no-texinfo.tex automake option. We also have one in texinfo/texinfo.tex, not sure if we should point to that, or move it (or a newer version of it added with automake --add-missing) to top-level. Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled.

2015-07-25Revert "Sync readline/ to version 7.0 alpha"Patrick Palka94-10012/+4493
This reverts commit b558ff043d41ba8d17a82f5f9ae5f9dade66160e. This reverts commit 4a11f2065906976675808364ddbd1c0f77eea41f. 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.
2015-07-25Don't build readline's shared libs by defaultPatrick Palka3-2/+7
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/240 http://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.
2015-07-25Sync readline/ to version 7.0 alphaPatrick Palka94-4495/+10009
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".
