From 749ef8f891fb921cf7ad57062deae6fa8c13b501 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 23 Apr 2015 15:48:26 +0100 Subject: [PATCH] gdb_test_multiple match eof of any spawn_id Since silent handling of eof is usually the wrong thing to do, this patch makes gdb_test_multiple handle it for all $any_spawn_id. Currently, against gdbserver, interrupt.exp occasionaly fails like this: FAIL: gdb.base/interrupt.exp: send end of file gdb.log with expect debug output enabled shows: expect: does "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" (spawn_id exp8) match regular expression "end of file"? Gate "end of file"? gate=no expect: read eof expect: set expect_out(spawn_id) "exp8" expect: set expect_out(buffer) "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" FAIL: gdb.base/interrupt.exp: send end of file Note "expect: read eof" for spawn_id=exp8. exp8 is inferior_spawn_id/gdbserver_spawn_id. That means expect/gdb_test_multiple saw gdbserver exit before we got the expected gdb output. Since there's no explicit pattern for "eof", expect (and thus gdb_test_multiple) just returns. After this commit, we get instead: ERROR: Process no longer exists UNRESOLVED: gdb.base/interrupt.exp: send end of file Note that before we still got an FAIL because $saw_inferior_exit is 0 when we get to: gdb_assert { $saw_eof && $saw_inferior_exit } $msg Fixing the fail (now unresolved) will be the subject of a separate patch. gdb/testsuite/ChangeLog: 2015-04-23 Pedro Alves * lib/gdb.exp (gdb_test_multiple): Match eof/full_buffer/timeout on $any_spawn_id instead of only on $gdb_spawn_id. --- gdb/testsuite/ChangeLog | 5 +++++ gdb/testsuite/lib/gdb.exp | 4 ++++ 2 files changed, 9 insertions(+) diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 04ec209e4ee..c77bf3c5af3 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,8 @@ +2015-04-23 Pedro Alves + + * lib/gdb.exp (gdb_test_multiple): Match eof/full_buffer/timeout + on $any_spawn_id instead of only on $gdb_spawn_id. + 2015-04-21 Pierre Muller PR pascal/17815 diff --git a/gdb/testsuite/lib/gdb.exp b/gdb/testsuite/lib/gdb.exp index 7d8720b194e..73e55e3ea1f 100644 --- a/gdb/testsuite/lib/gdb.exp +++ b/gdb/testsuite/lib/gdb.exp @@ -692,6 +692,7 @@ proc gdb_test_multiple { command message user_code } { global inferior_exited_re upvar timeout timeout upvar expect_out expect_out + global any_spawn_id if { $message == "" } { set message $command @@ -918,6 +919,9 @@ proc gdb_test_multiple { command message user_code } { fail "$message (got breakpoint menu)" set result -1 } + + # Patterns below apply to any spawn id specified. + -i $any_spawn_id eof { perror "Process no longer exists" if { $message != "" } { -- 2.30.2
