http.c supports HTTP redirects of the form http://foo/info/refs?service=git-upload-pack -> http://anything -> http://bar/info/refs?service=git-upload-pack (that is to say, as long as the Git part of the path and the query string is preserved in the final redirect destination, the intermediate steps can have any URL). However, if one of the intermediate steps results in an HTTP exception, a confusing "unable to update url base from redirection" message is printed instead of a Curl error message with the HTTP exception code. This was introduced by 2 commits. Commitc93c92f("http: update base URLs when we see redirects", 2013-09-28) introduced a best-effort optimization that required checking if only the "base" part of the URL differed between the initial request and the final redirect destination, but it performed the check before any HTTP status checking was done. If something went wrong, the normal code path was still followed, so this did not cause any confusing error messages until commit6628eb4("http: always update the base URL for redirects", 2016-12-06), which taught http to die if the non-"base" part of the URL differed. Therefore, teach http to check the HTTP status before attempting to check if only the "base" part of the URL differed. This commit teaches http_request_reauth to return early without updating options->base_url upon an error; the only invoker of this function that passes a non-NULL "options" is remote-curl.c (through "http_get_strbuf"), which only uses options->base_url for an informational message in the situations that this commit cares about (that is, when the return value is not HTTP_OK). The included test checks that the redirect scheme at the beginning of this commit message works, and that returning a 502 in the middle of the redirect scheme produces the correct result. Note that this is different from the test in commit6628eb4("http: always update the base URL for redirects", 2016-12-06) in that this commit tests that a Git-shaped URL (http://.../info/refs?service=git-upload-pack) works, whereas commit6628eb4tests that a non-Git-shaped URL (http://.../info/refs/foo?service=git-upload-pack) does not work (even though Git is processing that URL) and is an error that is fatal, not silently swallowed.
