Summary: racy: gdb.mi/ must not use gdb_test_multiple
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
AssignedTo: unassigned@sourceware.org
ReportedBy: jan.kratochvil@redhat.com
gdb_test_multiple contains
-re "\r\n$gdb_prompt $" {
if ![string match "" $message] then {
fail "$message"
but this may falsely match an unfinished output expected to be matched by:
gdb_test_multiple "-environment-path" "-environment-path" {
-re "\\\^done,path=\"\(.*\)\"\r\n$mi_gdb_prompt" {
as mi_gdb_prompt is (without the angle brackets, ^M as \r\n delimiter):
<[(]gdb[)] ^M
>
while gdb_prompt is (without the angle brackets):
<\(gdb\)>
Unfortunately there ar 23 uses of gdb_test_multiple in gdb.mi/*.exp.
PASS: gdb.mi/mi2-basics.exp: environment-pwd operation
-environment-path^M
^done,path="/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin"^M
-(gdb) ^M
+(gdb) FAIL: gdb.mi/mi2-basics.exp: -environment-path
Expecting: ^(207-environment-path[^M
]+)?(207\^done,path="/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin"[^M

[ ]*)
+^M

207^done,path="/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin"^M

-PASS: gdb.mi/mi2-basics.exp: environment-path no-args operation
+FAIL: gdb.mi/mi2-basics.exp: environment-path no-args operation

The fact that it works most of the time appears only to be a fortunate accident. Should we have an mi_gdb_test_multiple instead? Either that, or I think we should consider reverting all gdb_test_multiple uses under gdb.mi/ back to send_gdb/gdb_test. They were added not that long ago.
