repo = gh_client.repository("django", "django")
HTTPS certificate expiration
def get_expiration_date(host): ssl_context = ssl.create_default_context() with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
sock = ssl_context.wrap_socket(sock, server_hostname=host) sock.connect((host, 443)) expiration = ssl.cert_time_to_seconds(sock.getpeercert()["notAfter"]) return datetime.datetime.fromtimestamp(expiration)
while True: for host in MY_DOMAINS: expiration = get_expiration_date(host) if
expiration - datetime.datetime.now() < CUTOFF: file_an_issue(gh_client, host, expiration) time.sleep(3600)
def file_an_issue(gh_client, host, expiration): gh_client.create_issue( "django", "django", "Cert expiring soon:
{}".format(host), "The cert for `{}` expires on {}, get a new one!".format( host, expiration ), "alex", labels=["ssl-cert"] )

Response(status=200) body = json.load(request.stream) if body.get("action") not in {"opened", "reopened", "synchronize"}: return Response(status=200)
issue = repo.issue(body["number"]) pr = repo.pull_request(issue.number) changed_files = (f.filename for
f in pr.iter_files()) if "django/utils/crypto.py" in changed_files: issue.add_labels("security")
