2019-10-23Move readline to the readline/readline subdirectoryTom Tromey1-3249/+0
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 a8a5dbcab8df0b3a9e04745d4fe8d64740acb323. 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.

2015-07-25Revert "Sync readline/ to version 7.0 alpha"Patrick Palka1-344/+159
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.
2015-07-25Sync readline/ to version 7.0 alphaPatrick Palka1-159/+344
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".
