From ccbbd8bf66ca88385a34b16abcc1d5a800650d3a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Sun, 24 Mar 2019 08:09:46 -0400 Subject: http: normalize curl results for dumb loose and alternates fetches If the dumb-http walker encounters a 404 when fetching a loose object, it then looks at any http-alternates for the object. The 404 check is implemented by missing_target(), which checks not only the http code, but also that we got an http error from the CURLcode. That broke when we stopped using CURLOPT_FAILONERROR in 17966c0a63 (http: avoid disconnecting on 404s for loose objects, 2016-07-11), since our CURLcode will now be CURLE_OK. As a result, fetching over dumb-http from a repository with alternates could result in Git printing "Unable to find abcd1234..." and aborting. We could probably fix this just by loosening missing_target(). However, there's other code which looks at the curl result, and it would have to be tweaked as well. Instead, let's just normalize the result the same way the smart-http code does. There's a similar case in processing the alternates (where we failover from "info/http-alternates" to "info/alternates"). We'll give it the same treatment. After this patch, we should be hitting all code paths that need this normalization (notably absent here is the http_pack_request path, but it does not use FAILONERROR, nor missing_target()).
