From 909a6a1eb92ceacb983bcff088fb512352929c46 Mon Sep 17 00:00:00 2001 From: Klement Sekera Date: Tue, 8 Aug 2017 04:33:53 +0200 Subject: make test: detect hung tests Run tests in a forked process with a set of pipes to communicate keep-alives and overall result. This allows us to detect when e.g. vpp dies mid-API call causing the test to hang waiting for response (which will never come since vpp died). Support setting a (per test case) TIMEOUT make test option to set timeout, with a default timeout of 120 seconds. Example - fail the test suite if any test-case fails to finish within 300s: make TIMEOUT=300 test Change-Id: I0d04f26a7232968f4bf043adf5d5b508f5018717 Signed-off-by: Klement Sekera --- test/debug.py | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 test/debug.py (limited to 'test/debug.py') diff --git a/test/debug.py b/test/debug.py new file mode 100644 index 00000000000..4516b8c150b --- /dev/null +++ b/test/debug.py @@ -0,0 +1,23 @@ +""" debug utilities """ + +import os +import pexpect + +gdb_path = '/usr/bin/gdb' + + +def spawn_gdb(binary_path, core_path, logger): + if os.path.isfile(gdb_path) and os.access(gdb_path, os.X_OK): + # automatically attach gdb + gdb_cmdline = "%s %s %s" % (gdb_path, binary_path, core_path) + gdb = pexpect.spawn(gdb_cmdline) + gdb.interact() + try: + gdb.terminate(True) + except: + pass + if gdb.isalive(): + raise Exception("GDB refused to die...") + else: + logger.error("Debugger '%s' does not exist or is not an " + "executable.." % gdb_path) -- cgit 1.2.3-korg
