2016-06-06Escape reserved filename charactersLoïc Hoguin
Note that this commit has currently only been tested on Linux. It might be incomplete for other platforms.
2016-06-06Static: Fix status code returned with empty path_infoLoïc Hoguin
2016-03-05Initial commit with connection/streamsLoïc Hoguin
Breaking changes with previous commit. This is a very large change, and I am giving up on making a single commit that fixes everything. More commits will follow slowly adding back features, introducing new tests and fixing the documentation. This change contains most of the work toward unifying the interface for handling both HTTP/1.1 and HTTP/2. HTTP/1.1 connections are now no longer 1 process per connection; instead by default 1 process per request is also created. This has a number of pros and cons. Because it has cons, we also allow users to use a lower-level API that acts on "streams" (requests/responses) directly at the connection process-level. If performance is a concern, one can always write a stream handler. The performance in this case will be even greater than with Cowboy 1, although all the special handlers are unavailable. When switching to Websocket, after the handler returns from init/2, Cowboy stops the stream and the Websocket protocol takes over the connection process. Websocket then calls websocket_init/2 for any additional initialization such as timers, because the process is different in init/2 and websocket_*/* functions. This however would allow us to use websocket_init/2 for sending messages on connect, instead of sending ourselves a message and be subject to races. Note that websocket_init/2 is optional. This is all a big change and while most of the tests pass, some functionality currently doesn't. SPDY is broken and will be removed soon in favor of HTTP/2. Automatic compression is currently disabled. The cowboy_req interface probably still have a few functions that need to be updated. The docs and examples do not refer the current functionality anymore. Everything will be fixed over time. Feedback is more than welcome. Open a ticket!
2014-10-03Replace some /binary to /bits in binary pattern matchingLoïc Hoguin
We don't need the extra check for multiple of 8 bits.
2014-09-30Improve handler interface and documentationLoïc Hoguin
This change simplifies a little more the sub protocols mechanism. Aliases have been removed. The renaming of loop handlers as long polling handlers has been reverted. Plain HTTP handlers now simply do their work in the init/2 callback. There is no specific code for them. Loop handlers now follow the same return value as Websocket, they use ok to continue and shutdown to stop. Terminate reasons for all handler types have been documented. The terminate callback is now appropriately called in all cases (or should be). Behaviors for all handler types have been moved in the module that implement them. This means that cowboy_handler replaces the cowboy_http_handler behavior, and similarly cowboy_loop replaces cowboy_loop_handler, cowboy_websocket replaces cowboy_websocket_handler. Finally cowboy_rest now has the start of a behavior in it and will have the full list of optional callbacks defined once Erlang 18.0 gets released. The guide has been reorganized and should be easier to follow.
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.

2013-11-02Review, improve and document the static files handlerLoïc Hoguin
Changes include: * Much simplified route configuration. * Etag generation is now enabled by default. * Web mimetypes are now detected by default. A bigger list of mimetypes can be detected without any additional library. * Mimetypes can no longer be specified as a list. Copying this list for new connections is too costy. You can easily convert it into a function and pass that function to the handler instead. * You can however specify a single hardcoded mimetype. Mostly useful when serving a single file, like an index.html file, to avoid extra operations. * Specifying a path as a list of tokens is not possible anymore. Use either a binary or a string. * Using a private directory will not work if the application was not started properly. Cowboy will not attempt to find the location of this directory if the VM doesn't know it, as this caused issues in some setups. * Overall the code has been much simplified and clarified, and of course has now been documented.

2013-01-05Change the response body streaming fun interfaceLoïc Hoguin
Before we were required to get the socket and transport ourselves, now they're passed to the function.
2012-12-01Use Transport:sendfile/2 from RanchLoïc Hoguin
This removes a bunch of unneeded code, including code that was made for R14 which we don't support anymore. Note that the dependency on Ranch was updated, so you will need to update Ranch for the new code to work.
2012-11-29static: Allow passing the mimetype fun as a {M, F} tupleLoïc Hoguin
2012-11-27Fix dispatch documentation with regards to the <<"*">> pathLoïc Hoguin
2012-10-25Mimetype lookup expects lowercase extensionsLoïc Hoguin
We handle extensions in a case-insensitive manner when looking for a mimetype for a file. Extensions are thus lowered.
2012-10-19Fix examples in cowboy_static edocLoïc Hoguin
2012-09-21Don't use decode_packet/3 for parsing the request-lineLoïc Hoguin
First step in making all methods and header names binaries to get rid of many inconsistencies caused by decode_packet/3. Methods are all binary now. Note that since they are case sensitive, the usual methods become <<"GET">>, <<"POST">> and so on.
2012-09-15Change type #http_req{} to cowboy_req:req()Loïc Hoguin
This removes cowboy_static's dependency on http.hrl.
