Libcurl expects that headers are iterated in the same order that they
are recieved. Previously this caused curl tests 580 and 581 to fail.
This necessitated exposing a way to preserve the original ordering of
http headers.
SUMMARY OF CHANGES: Add a new data structure called OriginalHeaderOrder that
represents the order in which headers originally appear in a HTTP
message. This datastructure is `Vec<(Headername, multimap-index)>`.
This vector is ordered by the order which headers were recieved.
Add the following ffi functions:
- ffi::client::hyper_clientconn_options_set_preserve_header_order : An
ffi interface to configure a connection to preserve header order.
- ffi::client::hyper_clientconn_options_set_preserve_header_case : An
ffi interface to configure a connection to preserve header case.
- Add a new option to ParseContext, and Conn::State called `preserve_header_order`.
This option, and all the code paths it creates are behind the `ffi`
feature flag. This should not change performance of response parsing for
non-ffi users.
Closes#2780
BREAKING CHANGE: hyper_clientconn_options_new no longer
sets the http1_preserve_header_case connection option by default.
Users should now call
hyper_clientconn_options_set_preserve_header_case
if they desire that functionality.
This defines an extension type used in requests for the client that is
used to setup a callback for receipt of informational (1xx) responses.
The type isn't currently public, and is only usable in the C API.
Clean up the script so that any unexpected error terminates the
script, and stop suppressing errors that may contain useful
information (for example, that you are using the stable version but
need to use the nightly).
This is useful because if hyper.h is not up to date going forward the
CI should flag it. As is, there are a bunch of changes to hyper.h that
have not been checked in (or were generated by a newer version of the
cbindgen script.)
Fixes#2483.
This adds an internal ability to copy the HTTP/1 reason-phrase and place
it in the `http::Extensions` of a response, if it doesn't match the
canonical reason. This could be exposed in the Rust API later, but for
now it is only used by the C API.
