File gdb-testsuite-add-missing-initial-prompt-read-in-multidictionary.exp.patch of Package gdb
[gdb/testsuite] Add missing initial prompt read in multidictionary.exp When running multidictionary.exp in conjunction with: ... $ stress -c $(($(cat /proc/cpuinfo | grep -c "^processor") + 1)) ... we get: ... Running gdb/testsuite/gdb.dwarf2/multidictionary.exp ... ERROR: Couldn't load multidictionary into gdb. === gdb Summary === nr of unresolved testcases 1 ... The multidictionary test-case needs -readnow, and achieves this using: ... gdb_spawn_with_cmdline_opts "-readnow" gdb_load ... but the initial gdb prompt is not read. Usually, the following gdb_load command accidentally consumes that initial prompt (at the gdb_expect for the kill command in gdb_file_cmd). But under high load, that doesn't happen and we run into the error. Fix this by consuming the initial gdb prompt after spawning gdb. Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-07-23 Tom de Vries <tdevries@suse.de> PR testsuite/24842 * gdb.dwarf2/multidictionary.exp: Consume initial prompt after gdb_spawn_with_cmdline_opts. --- gdb/testsuite/gdb.dwarf2/multidictionary.exp | 6 ++++++ 2 files changed, 12 insertions(+) diff --git a/gdb/testsuite/gdb.dwarf2/multidictionary.exp b/gdb/testsuite/gdb.dwarf2/multidictionary.exp index 5588ef2144..c307ed8adc 100644 --- a/gdb/testsuite/gdb.dwarf2/multidictionary.exp +++ b/gdb/testsuite/gdb.dwarf2/multidictionary.exp @@ -148,6 +148,12 @@ if {[build_executable $testfile.exp $testfile [list $asm_file $srcfile] {}] \ # We force the DIEs above to be read in via "-readnow". gdb_spawn_with_cmdline_opts "-readnow" +set test "initial prompt" +gdb_test_multiple "" $test { + -re ".*$gdb_prompt $" { + pass "$test" + } +} gdb_load $binfile # All we need to do is check whether GDB is alive.
