2014-09-26Unify the init and terminate callbacksLoïc Hoguin
This set of changes is the first step to simplify the writing of handlers, by removing some extraneous callbacks and making others optional. init/3 is now init/2, its first argument being removed. rest_init/2 and rest_terminate/2 have been removed. websocket_init/3 and websocket_terminate/3 have been removed. terminate/3 is now optional. It is called regardless of the type of handler, including rest and websocket. The return value of init/2 changed. It now returns {Mod, Req, Opts} with Mod being either one of the four handler type or a custom module. It can also return extra timeout and hibernate options. The signature for sub protocols has changed, they now receive these extra timeout and hibernate options. Loop handlers are now implemented in cowboy_long_polling, and will be renamed throughout the project in a future commit.
2014-09-23Breaking update of the cowboy_req interfaceLoïc Hoguin
Simplify the interface for most cowboy_req functions. They all return a single value except the four body reading functions. The reply functions now only return a Req value. Access functions do not return a Req anymore. Functions that used to cache results do not have a cache anymore. The interface for accessing query string and cookies has therefore been changed. There are now three query string functions: qs/1 provides access to the raw query string value; parse_qs/1 returns the query string as a list of key/values; match_qs/2 returns a map containing the values requested in the second argument, after applying constraints and default value. Similarly, there are two cookie functions: parse_cookies/1 and match_cookies/2. More match functions will be added in future commits. None of the functions return an error tuple anymore. It either works or crashes. Cowboy will attempt to provide an appropriate status code in the response of crashed handlers. As a result, the content decode function has its return value changed to a simple binary, and the body reading functions only return on success.
2014-06-02Add request body reading optionsLoïc Hoguin
The options were added to allow developers to fix timeout issues when reading large bodies. It is also a cleaner and easier to extend interface. This commit deprecates the functions init_stream, stream_body and skip_body which are no longer needed. They will be removed in 1.0. The body function can now take an additional argument that is a list of options. The body_qs, part and part_body functions can too and simply pass this argument down to the body call. There are options for disabling the automatic continue reply, setting a maximum length to be returned (soft limit), setting the read length and read timeout, and setting the transfer and content decode functions. The return value of the body and body_qs have changed slightly. The body function now works similarly to the part_body function, in that it returns either an ok or a more tuple depending on whether there is additional data to be read. The body_qs function can return a badlength tuple if the body is too big. The default size has been increased from 16KB to 64KB. The default read length and timeout have been tweaked and vary depending on the function called. The body function will now adequately process chunked bodies, which means that the body_qs function will too. But this means that the behavior has changed slightly and your code should be tested properly when updating your code. The body and body_qs still accept a length as first argument for compatibility purpose with older code. Note that this form is deprecated and will be removed in 1.0. The part and part_body function, being new and never having been in a release yet, have this form completely removed in this commit. Again, while most code should work as-is, you should make sure that it actually does before pushing this to production.
