When running test-case gdb.tui/resize-2.exp with taskset -c 0, I sometimes run into: ... tui disable^[[40;1H^M(gdb) PASS: $exp: tui disable ^M^[[K(gdb) FAIL: $exp: two prompt redisplays after resize (timeout) ... The test-case does "Term::resize 24 80 0" while having the settings of an earlier "Term::resize 40 90", so both dimensions change. When TUI is enabled, we call Term::resize with wait_for_msg == 1, and the proc: - calls stty to change one dimension, - waits for the message (enabled by "maint set tui-resize-message on") confirming the resize has happened, - calls stty to change the other dimension, and again - waits for the message confirming the resize has happened. Since TUI is disabled, we call Term::resize with wait_for_msg == 0 because the message is not printed, so stty is called twice, and afterwards we check for the results of the two resizes, which is the test that is failing. The problem is that not waiting for a response after each stty call opens up the possibility of the responses being merged. Fix this by calling Term::resize twice, changing one dimension at a time, and waiting for a single prompt redisplay after each one. Tested on x86_64-linux.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
