X-Git-Url: https://git.rkrishnan.org/%5B/%5D%20/uri/htmlfontify-example.html?a=commitdiff_plain;h=521754b5062cfaddf0927a3b5e9b8e78eda66c25;p=tahoe-lafs%2Ftahoe-lafs.git test_runner.py: fix RunNode.test_introducer to not rely on the mtime of introducer.furl to detect when the node has restarted. Instead we detect when node.url has been written. refs #1385 --- diff --git a/src/allmydata/test/test_runner.py b/src/allmydata/test/test_runner.py index 6dfa7ee2..22678f6f 100644 --- a/src/allmydata/test/test_runner.py +++ b/src/allmydata/test/test_runner.py @@ -246,7 +246,7 @@ class CreateNode(unittest.TestCase): # 'create-node', and disabled for 'create-client'. tahoe_cfg = os.path.join(n1, "tahoe.cfg") self.failUnless(os.path.exists(tahoe_cfg)) - content = open(tahoe_cfg).read() + content = fileutil.read(tahoe_cfg) if kind == "client": self.failUnless(re.search(r"\n\[storage\]\n#.*\nenabled = false\n", content), content) else: @@ -352,11 +352,20 @@ class RunNode(common_util.SignalMixin, unittest.TestCase, pollmixin.PollMixin, HOTLINE_FILE = os.path.join(c1, "suicide_prevention_hotline") TWISTD_PID_FILE = os.path.join(c1, "twistd.pid") INTRODUCER_FURL_FILE = os.path.join(c1, "introducer.furl") + NODE_URL_FILE = os.path.join(c1, "node.url") + CONFIG_FILE = os.path.join(c1, "tahoe.cfg") d = self.run_bintahoe(["--quiet", "create-introducer", "--basedir", c1]) def _cb(res): out, err, rc_or_sig = res self.failUnlessEqual(rc_or_sig, 0) + + # This makes sure that node.url is written, which allows us to + # detect when the introducer restarts in _node_has_restarted below. + config = fileutil.read(CONFIG_FILE) + self.failUnlessIn('\nweb.port = \n', config) + fileutil.write(CONFIG_FILE, config.replace('\nweb.port = \n', '\nweb.port = 0\n')) + # by writing this file, we get ten seconds before the node will # exit.
