2018-11-09Add sendfile support to cowboy_req:stream_bodyLoïc Hoguin
It is now possible to stream one or more sendfile tuples. A simple example of what can now be done would be for example to build a tar file on the fly using the sendfile syscall for sending the files, or to support Range requests with more than one range with the sendfile syscall. When using cowboy_compress_h unfortunately we have to read the file in order to send it. More options will be added at a later time to make sure users don't read too much into memory. This is a new feature however so existing code is not affected. Also rework cowboy_http's data sending to be flatter.

2018-08-06Add missing log command to the commands() typeLoïc Hoguin
2018-06-28Introduce undocumented option loggerLoïc Hoguin
This commit reworks the logging that Cowboy does via error_logger to make the module that will do the actual logging configurable. The logger module interface must be the same as logger and lager: a separate function per log level with the same log levels they support. The default behavior remains to call error_logger, although some messages were downgraded to warnings instead of errors. Since error_logger only supports three different log levels, some messages may get downgraded/upgraded depending on what the original log level was to make them compatible with error_logger. The {log, Level, Format, Args} command was also added to stream handlers. Stream handlers should use this command to log messages because it allows writing a stream handler to intercept some of those messages and extract information or block them as necessary. The logger option only applies to Cowboy itself, not to the messages Ranch logs, so more work remains to be done in that area.

2017-03-27Add the early_error cowboy_stream callbackLoïc Hoguin
This callback is called when an error occurs before the request (including headers, excluding body) was fully received. The init/3 callback will not be called. The callback receives the partial Req object (possibly empty), the reason for the error and the response command that the server will send. It allows you to be aware of the error and possibly modify the response before it is sent.
2017-01-16Add support for multiple stream handlersLoïc Hoguin
The stream handlers can be specified using the protocol option 'stream_handlers'. It defaults to [cowboy_stream_h]. The cowboy_stream_h module currently does not forward the calls to further stream handlers. It feels like an edge case; usually we'd want to put our own handlers between the protocol code and the request process. I am therefore going to focus on other things for now. The various types and specifications for stream handlers have been updated and the cowboy_stream module can now be safely used as a behavior. The interface might change a little more, though. This commit does not include tests or documentation. They will follow separately.

2015-06-11Add HTTP/2 support preview2.0.0-pre.2Loïc Hoguin
This commit is not only an early preview of HTTP/2, it is an early preview of the new Cowboy architecture that will be presented tomorrow in my talk. If you have found it before the talk, great! It's not complete so you better go watch the talk anyway.
