http: support sending custom HTTP headers
We introduce a way to send custom HTTP headers with all requests. This allows us, for example, to send an extra token from build agents for temporary access to private repositories. (This is the use case that triggered this patch.) This feature can be used like this: git -c http.extraheader='Secret: sssh!' fetch $URL $REF Note that `curl_easy_setopt(..., CURLOPT_HTTPHEADER, ...)` takes only a single list, overriding any previous call. This means we have to collect _all_ of the headers we want to use into a single list, and feed it to cURL in one shot. Since we already unconditionally set a "pragma" header when initializing the curl handles, we can add our new headers to that list. For callers which override the default header list (like probe_rpc), we provide `http_copy_default_headers()` so they can do the same trick. Big thanks to Jeff King and Junio Hamano for their outstanding help and patient reviews. Signed-off-by: Johannes Schindelin <> Reviewed-by: Jeff King <> Signed-off-by: Junio C Hamano <>
