test appid %s status:%d

Error message

test appid %s status:%d

What it means

test_appid_exist probed a GAE appid and got an HTTP status other than 200 (and not the quota-related 503), so the appid likely isn't deployed or is misconfigured. The warning logs the failing status before content is checked for the GoAgent marker.

Solutions

  1. Deploy the GoAgent app to the appid (use the deploy command in web UI)
  2. Verify the appid string in config matches the GAE application ID exactly
  3. Check appstatus via the GAE console to confirm the app exists and serves 200
Defensive patterns

Strategy: validation

Validate before calling

# before enabling an appid, confirm the GAE app is deployed
import urllib2
r = urllib2.urlopen('https://%s.appspot.com/_gh/' % appid)
assert r.getcode() == 200

Try / catch

try:
    ok = test_appid(appid)
except Exception:
    ok = False

Prevention

When it happens

Trigger: Calling test_appid for an appid that was never deployed, was deleted, or the appid string is misspelled; the GAE app returns 404/500.

Common situations: First-run setup where the user hasn't uploaded the GoAgent GAE app yet; appid renamed in config but not on GAE; Google App Engine quota or auth changes.
