This is a breaking change. A call to `Response::headers()` can be
replaced with `Response::headers().iter()`. A call to
`Response::header_values()` can be replaced with
`Response::headers().get()`.
This commit introduces TLS support, provided by `rustls` and a fork of
`hyper-rustls`. TLS support is enabled via the `tls` feature and
activated when the `tls` configuration parameter is set. A new
`hello_tls` example illustrates its usage.
This commit also introduces more robust and complete configuration
settings via environment variables. In particular, quoted string,
array, and table (dictionaries) based configuration parameters can now
be set via environment variables.
Resolves#28.
This is a breaking change.
This commit introduces `RawStr` to forms. In particular, after this
commit, the `&str` type no longer implements `FromFormValue`, and so it
cannot be used as a field in forms. Instad, the `&RawStr` can be used.
The `FormItems` iterator now returns an `(&RawStr, &RawStr)` pair.
This is a breaking change.
This commit changes the meaning of the `format` route attribute when
used on non-payload carrying requests (GET, HEAD, CONNECT, TRACE, and
OPTIONS) so that it matches against the preferred media type in the
`Accept` header of the request. The preferred media type is computed
according to the HTTP 1.1 RFC, barring a few specificty rules to come.
This is a breaking change. It modifies collisions with respect to query
parameters as well as the default ranking of routes.
A route that does not specify query parameters will now match against
requests with _and without_ query parameters, assuming all other
elements of the route match as well. A route that _does_ specify query
parameters will only match requests with query parameters; this remains
true.
To accommodate this change in the most natural manner possible, the
default rankings of routes have changed as illustrated below:
|-------------+-------+----------+---------------|
| static path | query | new rank | previous rank |
|-------------+-------+----------+---------------|
| yes | yes | -4 | 0 |
| yes | no | -3 | 0 |
| no | yes | -2 | 1 |
| no | no | -1 | 1 |
|-------------+-------+----------+---------------|
In other words, the most specific routes, with preference for paths over
queries, are ranked highest (lower number).
This is a (minor) breaking change. If `rocket.launch()` is the last expression
in a function, the return type will change from `()` to `LaunchError`. A simple
workaround that preserves the previous functionality is to simply add a
semicolon after `launch()`: `rocket.launch();`.
resolves#34
This commit includes the following additions:
* A `session` example was added.
* `Config::take_session_key` was removed.
* If a `session_key` is not supplied, one is automatically generated.
* The `Session` type implements signed, encrypted sessions.
* A `Session` can be retrieved via its request guard.
This commit involves several breaking changes:
* `session_key` config param must be a 256-bit base64 encoded string.
* `FromRequest` is implemented for `Cookies`, not `Cookie`.
* Only a single `Cookies` instance can be retrieved at a time.
* `Config::take_session_key` returns a `Vec<u8>`.
* `Into<Header>` is implemented for `&Cookie`, not `Cookie`.
This commit changes the routing algorithm. In particular, it enforces
precise matching of formats. With this change, a route with a specified
format only matches requests that have the same format specified. A
route with no format specified matches any request's format. This is
contrast to the previous behavior, where a route without a specified
format would match requests regardless of their format or whether one
was specified.
This commit also changes the following:
* The return type of the 'content_type' method of 'Request' is now
'Option<ContentType>'.
* The 'ContentType' request guard forwards when the request has no
specified ContentType.
* The 'add_header' and 'replace_header' methods take the header
argument generically.
Closes#120.
* The `unmanaged_state` lint emits a warning when a `State<T>` request
guard is used without an accompanying `manage` call for `T`.
* The `unmounted_route` lint emits a warning when a route declared via
a Rocket attribute is not mounted via a call to `mount`.
There is one known shortcoming of these lints at present: _any_ call to
`manage` or `mount` marks state/routes as managed/mounted. This can be
an issue when an application uses more than one `Rocket` instance, with
different calls to `mount` and `manage` in each. The lints should
perform their analyses on a per-instance basis.
A few interesting notes on this breakage:
* `Cookie` how has a lifetime. It should be `'static'` everywhere.
* The `SetCookie` header is no longer reexported.
* Instead, `Cookie` implements `Into<Header>` for Set-Cookie.
This is a complete rework of `Responder`s and of the http backend in
general. This gets Rocket one step closer to HTTP library independence,
enabling many future features such as transparent async I/O, automatic
HEAD request parsing, pre/post hooks, and more.
Summary of changes:
* `Responder::response` no longer takes in `FreshHyperResponse`.
Instead, it returns a new `Response` type.
* The new `Response` type now encapsulates a full HTTP response. As a
result, `Responder`s now return it.
* The `Handler` type now returns an `Outcome` directly.
* The `ErrorHandler` returns a `Result`. It can no longer forward,
which made no sense previously.
* `Stream` accepts a chunked size parameter.
* `StatusCode` removed in favor of new `Status` type.
* `ContentType` significantly modified.
* New, lightweight `Header` type that plays nicely with `Response`.
This commit includes the following important API changes:
* The `form` route parameter has been removed.
* The `data` route parameter has been added.
* Forms are not handled via the `data` parameter and `Form` type.
* Removed the `data` parameter from `Request`.
* Added `FromData` conversion trate and default implementation.
* Added `DataOutcome` enum, which is the return type of `from_data`.
* 'FromData' is now used to automatically derive the `data` parameter.
* Moved `form` into `request` module.
* Removed `Failure::new` in favor of direct value construction.
This commit includes the following important package additions:
* Added a 'raw_upload' example.
* `manual_routes` example uses `Data` parameter.
* Now building and running tests with `--all-features` flag.
* All exmaples have been updated to latest API.
* Now using upstream Tera.
This commit includes the following important fixes:
* Any valid ident is now allowed in single-parameter route parameters.
* Lifetimes are now properly stripped in code generation.
* `FromForm` derive now works on empty structs.
Summary of changes:
* Request no longer has a lifetime parameter.
* Handler type now includes a `Data` parameter.
* Response is now an enum that is either `Complete` or `Forward`.
* Outcome enum is now one of: Success, Failure, Forward.
* Outcome::Foward for Responses must include StatusCode.
* Responders are now final: they cannot forward to requests. (!!)
* Responsers may only forward to catchers. (!!)
* Response no longer provides wrapping methods.
* Route is now cloneable.
This change is fundamental to enabling streaming requests.
* All From* trait methods are now named like the trait.
* All From* traits have an associated Error type.
* Document all of the `form` module.
* Add codegen tests for auto-derived forms.
* The param parsing traits now live under Request.
* Add content-type responsers for JSON, HTML, and plain text.
* Use content-type responders in content_type example.
* Conditionally create Request `from` HypRequest.
* Clean-up dispatching and handling in main rocket.
* Change Level enum to Logging Level and reexport.
* Allow users to set logging level before launch.
* Fix content_type example error handling.
* Percent decode params when user requests `String`.
The error function now takes in a "RoutingError" structure. The idea is that the
structure includes all of the information necessary for a user to processor the
error as they wish. This interface is very incomplete and may change. At a
minimum, the error structure should include:
1) The request that failed.
2) Why the request failed.
3) The chain of attempted route matches, if any.
4) Something else?
A few important things needs to get this to be 'right':
1a. Have a way to return a response with a status code.
1b. Use that mechanism in the default catchers.
2. Automatically fill in that code from the #[error] handler.
3. Have a way for a responder to say if responding succeeded.
4. Try next highest ranking route if responding with one handler fails.
Added `error` decorator and `errors` macro.
The current idea is that you can have "catchers" for all valid errors code (in
range [400, 500). At the moment, catchers are just request handlers, and the
decorator expected an empty function signature for the error handler. Obviously,
this is pretty useless. Not sure on what the API should be here. But, progress.
Oh, one more thing: who should handle forwarding a request to a catcher?
Probably not the router. So, the main Rocket should?
Here's the idea: under the `Rocket` namespace should live things critical to
writing simple Rocket apps: Request, Response, Error, etc. Nothing should be
nested more than one level deep. Only items required for more complex things
(implementing uncommon traits, etc.) should be nested one level deep.
This commit is the first attempt at realizing this.
There's something going on with Hyper. When a 303 (see other) response is sent
in response to a POST, the browser does a GET to the location header. Hyper
somehow misreads the method parameter here, resulting in a route failer.
I need to MITM the connection to see exactly what the browser is sending and
what Hyper is receiving to see who's wrong.
Experimented with the new impl specialization features of Rust. They work! But
they're not quite there yet. Specifically, I was able to specialize on
`Responder`, but when trying to remove the macro in `FromParam`, it didn't work.
See https://github.com/rust-lang/rust/issues/31844.
At the moment, I simply install the first route I see into the Rocket struct
directly. This is quite terrible. What's worse is that I assume that the Route's
path and handler are static! The handler, actually, does have to be static, but
its response may have whatever (valid) lifetime, though I'm not sure anything
but `static makes sense. I'll think about it.
In any case, the weird `static` restrictions need to be removed, and I need to
think about which lifetimes are safe here. IE: Must all routes be static? Can I
use a closure as a route? (that'd be neat). If so, how do we make that work?
In any case, it's nice to see SOMETHING work. Yay!
Subset of list of changes:
* Split up decorator and macro into their own files.
* Fully parsing the path parameter and verifying against the function's args.
* Actually calling methods to fetch and convert the request parameters.
* Actually calling methods to convert the handler's return type.
* Sketched out more of the Request/Response structures.
Pretty close to having a fully working MVP.
Here's what works so far:
* The `route` decorator checks its inputs correctly. There's a nice utility
for doing this, and it's working quite well at the moment.
* The `route` decorator emits a `route_fn` and a `route_struct`. The `routes`
* macro prepends the path terminator with the route struct prefix. The
* `Rocket` library can read mount information (though not act on it properly
just yet) and launch a server using Hyper.
