From a97d00799a19d2516ca8fae4da9bf782ca6f2e37 Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Thu, 21 Feb 2019 12:24:41 -0800 Subject: remote-curl: use post_rpc() for protocol v2 also When transmitting and receiving POSTs for protocol v0 and v1, remote-curl uses post_rpc() (and associated functions), but when doing the same for protocol v2, it uses a separate set of functions (proxy_rpc() and others). Besides duplication of code, this has caused at least one bug: the auth retry mechanism that was implemented in v0/v1 was not implemented in v2. To fix this issue and avoid it in the future, make remote-curl also use post_rpc() when handling protocol v2. Because line lengths are written to the HTTP request in protocol v2 (unlike in protocol v0/v1), this necessitates changes in post_rpc() and some of the functions it uses; perform these changes too. A test has been included to ensure that the code for both the unchunked and chunked variants of the HTTP request is exercised. Note: stateless_connect() has been updated to use the lower-level packet reading functions instead of struct packet_reader. The low-level control is necessary here because we cannot change the destination buffer of struct packet_reader while it is being used; struct packet_buffer has a peeking mechanism which relies on the destination buffer being present in between a peek and a read.
