Hello,
I've updated libcurl (8.5.0 -> 8.6.0) in our http client and discovered
a regression:
when http server send non-empty http body in response of HEAD request
http client finish connection with CURLE_WEIRD_SERVER_REPLY.
Part of the difference in logs is below:
-* STATE: PERFORMING => DONE handle 0x55f9fb6727c8; line 2588
-* multi_done[DONE]: status: 0 prem: 0 done: 0
-* multi_done, not reusing connection=0, forbid=0, close=1, premature=0,
conn_multiplex=0
+* did not want a BODY, but seeing 4 bytes
+* readwrite_data() -> 8
+* Curl_readwrite() -> 8
+* multi_done[PERFORMING]: status: 8 prem: 1 done: 0
+* multi_done, not reusing connection=0, forbid=0, close=1, premature=1,
conn_multiplex=0
* The cache now contains 0 members
-* Curl_disconnect(conn #0, dead=0)
+* Curl_disconnect(conn #0, dead=1)
* Closing connection
+SystemError: curl: Weird server reply: Invalid argument
Message "did not want a BODY" [1] was introduced in commit [2].
Moreover, function that returns CURLE_WEIRD_SERVER_REPLY
contains a comment: "/* BODY arrives although we want none, bail out */".
I just want to make sure that is was done intentionally, because it
changes http client's behavior
and looks like a breaking change.
