From 016d66f512bbbd7d766f6244d989b4549d5b0d5b Mon Sep 17 00:00:00 2001 From: Lars Schneider Date: Wed, 3 May 2017 23:50:15 +0200 Subject: travis-ci: retry if Git for Windows CI returns HTTP error 502 or 503 The Git for Windows CI web app sometimes returns HTTP errors of "502 bad gateway" or "503 service unavailable" [1]. We also need to check the HTTP content because the GfW web app seems to pass through (error) results from other Azure calls with HTTP code 200. Wait a little and retry the request if this happens.
