At the same time renaming cowboy_http:content_type_params/3 to
cowboy_http:params/2 (with a default Acc of []) as this code isn't
useful only for content types.
We try to send a 500 error only if we didn't send the response
headers yet. If they were, then we have no way to be sure the
response was fully sent, nor should we assume anything about
how this will be handled client-side, so we do nothing more
and in both cases close the connection.
resp_body is set by cowboy_http_req:set_resp_body/2 which accepts
the input type iodata(). Update the resp_body field to use the same
type. Also update the cowboy_http_req:has_resp_body/2 function to
use the iolist_size/1 which works with both binary() and iolist()
values instead of the byte_size/1 function which only works with
binary() values.
This change makes the dependency on quoted optional
by adding a minimal urldecode function to cowboy.
A protocol option for setting the urldecoding function
has been added to the cowboy_http_protocol module.
The default value for this option is set to be
equivalent to the default settings for quoted.
{fun cowboy_http:urldecode/2, crash}
A note has been added in the README to document
how to use quoted instead of this function.
A field to store this option value has been added
to the state record in the cowboy_http_protocol
module and the http_req record in include/http.hrl
Functions that previously used quoted:from_url/1
has been updated to require an equivalent function
in addition to the previously required arguments.
This change removes a C compiler from the build
requirements of cowboy. It also removes the requirement
to cross compile the code if the target arch/OS
is different from the arch/OS used to build it.
These functions allow to set response headers and body in advance,
before calling any of the reply functions.
Also add has_resp_header/2 and has_resp_body/1 to check if the given
response headers have already been set.
This function doesn't try to add any additional header besides the
Connection: Upgrade header. It also doesn't accept a body.
It should be used for the intermediate reply to an upgrade process,
before the real reply is sent (if any, for example when using TLS).
Now Cowboy checks headers sent to the client for the 'Connection'
header value, parses it, and checks whether it contains a 'close'
or 'keep-alive' value. It makes sure to close or keep the connection
alive depending on the value found there, if any.
Also change chunked replies to not close the connection by default
unless the application requests it.
