2019-07-12[readline] Fix heap-buffer-overflow in update_lineTom de Vries1-0/+7
When: - building trunk gdb with '-fsanitize=address -lasan', - running gdb tests with "export ASAN_OPTIONS=detect_leaks=0", I run into a heap-buffer-overflow failure for gdb.base/utf8-identifiers.exp. In more detail, the libasan error report looks like this: ... ================================================================= ==22340==ERROR: AddressSanitizer: heap-buffer-overflow on address

2019-01-31Readline: Cleanup some warningsAlan Hayward1-0/+6
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.

2015-07-25Revert "Sync readline/ to version 7.0 alpha"Patrick Palka1-11/+0
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 Palka1-0/+5
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 Palka1-0/+6
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".

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.
