Tom de Vries	85f4cf41a8	[readline] Fix double free in _rl_scxt_dispose Consider the following scenario. We start gdb in TUI mode: ... $ gdb -q -tui ... and type ^R which gives us the reverse-isearch prompt in the cmd window: ... (reverse-i-search)`': ... and then type "foo", right-arrow-key, and ^C. In TUI mode, gdb uses a custom rl_getc_function tui_getc. When pressing the right-arrow-key, tui_getc: - attempts to scroll the TUI src window, without any effect, and - returns 0. The intention of returning 0 is mentioned here in tui_dispatch_ctrl_char: ... /* We intercepted the control character, so return 0 (which readline will interpret as a no-op). / return 0; ... However, after this 0 is returned by the rl_read_key () call in _rl_search_getchar, _rl_read_mbstring is called, which incorrectly interprets 0 as the first part of an utf-8 multibyte char, and tries to read the next char. In this state, the ^C takes effect and we run into a double free because _rl_isearch_cleanup is called twice. Both these issues need fixing independently, though after fixing the first we no longer trigger the second. The first issue is caused by the subtle difference between: - a char array containing 0 chars, which is zero-terminated, and - a char array containing 1 char, which is zero. In mbrtowc terms, this is the difference between: ... mbrtowc (&wc, "", 0, &ps); ... which returns -2, and: ... mbrtowc (&wc, "", 1, &ps); ... which returns 0. Note that _rl_read_mbstring calls _rl_get_char_len without passing it an explicit length parameter, and consequently it cannot distinguish between the two, and defaults to the "0 chars" choice. Note that the same problem doesn't exist in _rl_read_mbchar. Fix this by defaulting to the "1 char" choice in _rl_get_char_len: ... - if (_rl_utf8locale && l > 0 && UTF8_SINGLEBYTE(src)) + if (_rl_utf8locale && l >= 0 && UTF8_SINGLEBYTE(*src)) ... The second problem happens when the call to _rl_search_getchar in _rl_isearch_callback returns. At that point _rl_isearch_cleanup has already been called from the signal handler, but we proceed regardless, using a cxt pointer that has been freed. Fix this by checking for "RL_ISSTATE (RL_STATE_ISEARCH)" after the call to _rl_search_getchar: ... c = _rl_search_getchar (cxt); + if (!RL_ISSTATE (RL_STATE_ISEARCH)) + return 1; ...

Andrew Burgess	8f3babfaf8	gdb/readline: fix extra 'quit' message problem After these two commits: commit `4fb7bc4b14` Date: Mon Mar 7 13:49:21 2022 +0000 readline: back-port changes needed to properly detect EOF commit `91395d97d9` Date: Tue Feb 15 17:28:03 2022 +0000 gdb: handle bracketed-paste-mode and EOF correctly It was observed that, if a previous command is selected at the readline prompt using the up arrow key, then when the command is accepted (by pressing return) an unexpected 'quit' message will be printed by GDB. Here's an example session: (gdb) p 123 $1 = 123 (gdb) p 123 quit $2 = 123 (gdb) In this session the second 'p 123' was entered not by typing 'p 123', but by pressing the up arrow key to select the previous command. It is important that the up arrow key is used, typing Ctrl-p will not trigger the bug. The problem here appears to be readline's EOF detection when handling multi-character input sequences. I have raised this issue on the readline mailing list here: https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00012.html a solution has been proposed here: https://lists.gnu.org/archive/html/bug-readline/2022-04/msg00016.html This patch includes a test for this issue as well as a back-port of (the important bits of) readline commit: commit 2ef9cec8c48ab1ae3a16b1874a49bd1f58eaaca1 Date: Wed May 4 11:18:04 2022 -0400 fix for setting RL_STATE_EOF in callback mode That commit also includes some updates to the readline documentation and tests that I have not included in this commit. With this commit in place the unexpected 'quit' messages are resolved.	4 years ago
Andrew Burgess	4fb7bc4b14	readline: back-port changes needed to properly detect EOF This commit is a partial back-port of this upstream readline commit: commit 002d31aa5f5929eb32d0e0e2e8b8d35d99e59961 Author: Chet Ramey <chet.ramey@case.edu> Date: Thu Mar 3 11:11:47 2022 -0500 add rl_eof_found to public API; fix pointer aliasing problems \ with history-search-backward; fix a display problem with \ runs of invisible characters at the end of a physical \ screen line I have only pulled in the parts of this commit that relate to the new rl_eof_found global, and the RL_STATE_EOF state flag. These changes are needed in order to fix PR cli/28833, and are discussed in this thread to the bug-readline mailing list: https://lists.gnu.org/archive/html/bug-readline/2022-02/msg00021.html The above commit is not yet in any official readline release, but my hope is that now it has been merged into the readline tree it should be safe enough to back port this fix to GDB's tree. At some point in the future we will inevitably want to roll forward the version of readline that we maintain in the binutils-gdb repository. When that day comes the changes in this commit can be replaced with the latest upstream readline code, as I have not changed the meaning of this code at all from what is in upstream readline. This commit alone does not fix the PR cli/28833 issue, for that see the next commit, which changes GDB itself. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28833	4 years ago

Tom Tromey	bb69c5018b	Minor updates to readline configury Christian's recent patches to gnulib made me realize that readline should be changed to use AC_CONFIG_MACRO_DIRS (ACLOCAL_AMFLAGS is deprecated) and that it can put the automake options into configure.ac. I also added no-define to the automake options. This doesn't matter much (we don't generate a config.h here), but gnulib does it, and it does make configure slightly smaller. readline/ChangeLog 2019-11-15 Tom Tromey <tromey@adacore.com> * configure, Makefile.in: Rebuild. * configure.ac: Use AC_CONFIG_MACRO_DIRS.

Tom Tromey	6999161a2a	Move readline to the readline/readline subdirectory readline turns out to be a bit of a stumbling block for the project to move gdbsupport (and then gdbserver) to the top-level. The issue is that readline headers are intended to be included with names like "readline/readline.h". To support this, gdb effectively adds a -I option pointing to the top-level source directory -- but, importantly, this option is not used when the system readline is used. For gdbsupport, a -I option like this would always be needed, but that in turn would break the system readline case. This was PR build/17077, fixed in commit `a8a5dbcab8`. Previously, we had discussed this on the gdb-patches list in terms of removing readline from the tree https://sourceware.org/ml/gdb-patches/2019-09/msg00317.html However, Eli expressed some concerns, and Joel did as well (off-list). Given those concerns, and the fact that a patch-free local readline is relatively new in gdb (it was locally patched for years), I changed my mind and decided to handle this situation by moving the readline sources down a level. That is, upstream readline is now in readline/readline, and the top-level readline directory just contains the minimal configury needed to build that. This fixes the problem because, when gdb unconditionally adds a -I$(top_srcdir), this will not find readline headers. A separate -I will be needed instead, which is exactly what's needed for --with-system-readline. gdb/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. gdb/doc/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> * Makefile.in (READLINE_DIR): Update. readline/ChangeLog 2019-10-23 Tom Tromey <tom@tromey.com> Move old contents to readline/ subdirectory. * aclocal.m4, configure, configure.ac, .gitignore, Makefile.am, Makefile.in, README: New files.

The very first time this function is ever called its MINSIZE parameter is always 0 and the global LINE_SIZE is 1024. Prior to the above mentioned commits we spot that the line_state variables have not yet been initialised, and allocate them some new buffer, then we enter this loop: for (n = minsize; n < line_size; n++) { visible_line[n] = 0; invisible_line[n] = 1; } which would initialise everything from the incoming minimum up to the potentially extended upper line size. The problem is that the above patches added a new condition that would bump up the minsize like this: if (minsize <= _rl_screenwidth) / XXX - for gdb / minsize = _rl_screenwidth + 1; So, the first time this function is called the incoming MINSIZE is 0, the LINE_SIZE global is 1024, and if the _rl_screenwidth is 80, we see that MINSIZE will be pushed up to 80. We still notice that the line state is uninitialised and allocate some buffers, then we enter the initialisation loop: for (n = minsize; n < line_size; n++) { visible_line[n] = 0; invisible_line[n] = 1; } And initialise from 80 to 1023 i the newly allocated buffers, leaving 0 to 79 uninitialised. To confirm this is an issue, if we then look at rl_redisplay we see that a call to init_line_structures is followed first by a call to rl_on_new_line, which does initialise visible_line[0], but not invisible_line[0]. Later in rl_redisplay we have this logic: if (visible_line[0] != invisible_line[0]) rl_display_fixed = 0; The use of invisible_line[0] here will be undefined. Considering how this variable was originally initialised before the above patches, this patch modifies the initialisation loop in init_line_structures, to use the original value of MINSIZE. With this change the valgrind warning goes away. readline/ChangeLog: PR cli/24980 display.c (init_line_structures): Initialise line_state using original minsize value.	7 years ago

Simon Marchi	d0ac1c4488	Bump to autoconf 2.69 and automake 1.15.1 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.

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.

Patrick Palka	5836a818ec	Revert "Sync readline/ to version 7.0 alpha" 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.	11 years ago
Patrick Palka	b558ff043d	Don't build readline's shared libs by default 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.	11 years ago
Patrick Palka	4a11f20659	Sync readline/ to version 7.0 alpha 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".	11 years ago
