From e80061d934f25a0bb97aa4ec2f9ec35a9437d865 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Thu, 18 May 2023 07:58:20 +0200 Subject: [pushed] [gdb/testsuite] Fix gdb.tui/wrap-line.exp PR testsuite/30458 reports the following FAIL: ... PASS: gdb.tui/wrap-line.exp: width-auto-detected: cli: wrap ^CQuit (gdb) WARNING: timeout in accept_gdb_output Screen Dump (size 50 columns x 24 rows, cursor at column 6, row 3): 0 Quit 1 (gdb) 7890123456789012345678901234567890123456789 2 W^CQuit 3 (gdb) ... FAIL: gdb.tui/wrap-line.exp: width-auto-detected: cli: prompt after wrap ... The problem is that the regexp doesn't account for the ^C: ... gdb_assert { [Term::wait_for "^WQuit"] } "prompt after wrap" ... The ^C occurs occasionally. This is something we'd like to fix. It's reported as a readline problem here ( https://lists.gnu.org/archive/html/bug-readline/2023-06/msg00000.html ). For now, fix this by updating the regexp, and likewise in another place in the test-case where we use ^C. Tested on x86_64-linux.
