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.		2022-05-07 10:49:27 +01:00

README

This is an import of readline that is used by gdb.

To send patches, follow the gdb patch submission instructions in
../gdb/CONTRIBUTE.  For maintainers, see ../gdb/MAINTAINERS.

If you need to patch readline, please document the changes here.

To import, copy the upstream readline sources into the "readline"
subdirectory, remembering to (1) remove any files that were deleted
upstream, and (2) merge the one small configure.ac patch that gdb
carries.

If your import removes the need for a local patch, please remember to
update this file.

Individual upstream readline patches can be directly imported using
"git am".  You can see the current patch level by looking at
readline/patchlevel.
