Version 0.4.0 (Dec 06, 2018)

New Features

This release includes the following new features:

Codegen Rewrite

The rocket_codegen crate has been entirely rewritten using to-be-stable procedural macro APIs. We expect nightly breakages to drop dramatically, likely to zero, as a result. The new prelude import for Rocket applications is:

- #![feature(plugin)]
- #![plugin(rocket_codegen)]
+ #![feature(proc_macro_hygiene, decl_macro)]

- extern crate rocket;
+ #[macro_use] extern crate rocket;

The rocket_codegen crate should not be a direct dependency. Remove it from your Cargo.toml:

[dependencies]
- rocket = "0.3"
+ rocket = "0.4"
- rocket_codegen = "0.3"

Breaking Changes

This release includes many breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications when applicable.

  • Route and catcher attributes respect function privacy.

    To mount a route or register a catcher outside of the module it is declared, ensure that the handler function is marked pub or crate.

  • Query handling syntax has been completely revamped.

    A query parameter of <param> is now <param..>. Consider whether your application benefits from the revamped query string handling.

  • The #[error] attribute and errors! macro were removed.

    Use #[catch] and catchers! instead.

  • Rocket::catch() was renamed to Rocket::register().

    Change calls of the form .catch(errors![..]) to .register(catchers![..]).

  • The #[catch] attribute only accepts functions with 0 or 1 argument.

    Ensure the argument to the catcher, if any, is of type &Request.

  • json! returns a JsonValue, no longer needs wrapping.

    Change instances of Json(json!(..)) to json! and change the corresponding type to JsonValue.

  • All environments default to port 8000.

    Manually configure a port of 80 for the stage and production environments for the previous behavior.

  • Release builds default to the production environment.

    Manually set the environment to debug with ROCKET_ENV=debug for the previous behavior.

  • Form and LenientForm lost a lifetime parameter, get() method.

    Change a type of Form<'a, T<'a>> to Form<T> or Form<T<'a>>. Form<T> and LenientForm<T> now implement Deref<Target = T>, allowing for calls to .get() to be removed.

  • ring was updated to 0.13.

    Ensure all transitive dependencies to ring refer to version 0.13.

  • Uri was largely replaced by Origin.

    In general, replace the type Uri with Origin. The base and uri fields of Route are now of type Origin. The &Uri guard is now &Origin. Request::uri() now returns an Origin.

  • All items in rocket_contrib are namespaced behind modules.

    • Json is now json::Json
    • MsgPack is now msgpack::MsgPack
    • MsgPackError is now msgpack::Error
    • Template is now templates::Template
    • UUID is now uuid::Uuid
    • Value is replaced by json::JsonValue

  • TLS certificates require the subjectAltName extension.

    Ensure that your TLS certificates contain the subjectAltName extension with a value set to your domain.

  • Route paths, mount points, and LocalRequest URIs are strictly checked.

    Ensure your mount points are absolute paths with no parameters, ensure your route paths are absolute paths with proper parameter syntax, and ensure that paths passed to LocalRequest are valid.

  • Template::show() takes an &Rocket, doesn't accept a root.

    Use client.rocket() to get a reference to an instance of Rocket when testing. Use Template::render() in routes.

  • Request::remote() returns the actual remote IP, doesn't rewrite.

    Use Request::real_ip() or Request::client_ip() to retrieve the IP address from the "X-Real-IP" header if it is present.

  • Bind variant was added to LaunchErrorKind.

    Ensure matches on LaunchErrorKind include or ignore the Bind variant.

  • Cookies are automatically tracked and propagated by Client.

    For the previous behavior, construct a Client with Client::untracked().

  • UUID was renamed to Uuid.

    Use Uuid instead of UUID.

  • LocalRequest::cloned_dispatch() was removed.

    Chain calls to .clone().dispatch() for the previous behavior.

  • Redirect constructors take a generic type of T: TryInto<Uri<'static>>.

    A call to a Redirect constructor with a non-'static &str of the form Redirect::to(string) should become Redirect::to(string.to_string()), heap-allocating the string before being passed to the constructor.

  • The FromData impl for Form and LenientForm now return an error of type FormDataError.

    On non-I/O errors, the form string is stored in the variant as an &'f str.

  • Missing variant was added to ConfigError.

    Ensure matches on ConfigError include or ignore the Missing variant.

  • The FromData impl for Json now returns an error of type JsonError.

    The previous SerdeError is now the .1 member of the JsonError enum. Match and destruct the variant for the previous behavior.

  • FromData is now emulated by FromDataSimple.

    Change implementations, not uses, of FromData to FromDataSimple. Consider whether your implementation could benefit from transformations.

  • FormItems iterates over values of type FormItem.

    Map using .map(|item| item.key_value()) for the previous behavior.

  • LaunchErrorKind::Collision contains a vector of the colliding routes.

    Destruct using LaunchErrorKind::Collision(..) to ignore the vector.

  • Request::get_param() and Request::get_segments() are indexed by segment, not dynamic parameter.

    Modify the n argument in calls to these functions appropriately.

  • Method-based route attributes no longer accept a keyed path parameter.

    Change an attribute of the form #[get(path = "..")] to #[get("..")].

  • Json and MsgPack data guards no longer reject requests with an unexpected Content-Type

    To approximate the previous behavior, add a format = "json" route parameter when using Json or format = "msgpack" when using MsgPack.

  • Implemented Responder for Status. Removed Failure, status::NoContent, and status::Reset responders.

    Replace uses of Failure(status) with status directly. Replace status::NoContent with Status::NoContent. Replace status::Reset with Status::ResetContent.

  • Config::root() returns an Option<&Path> instead of an &Path.

    For the previous behavior, use config.root().unwrap().

  • Status::new() is no longer const.

    Construct a Status directly.

  • Config constructors return a Config instead of a Result<Config>.

  • ConfigError::BadCWD, Config.config_path were removed.

  • Json no longer has a default value for its type parameter.

  • Using data on a non-payload method route is a warning instead of error.

  • The raw_form_string method of Form and LenientForm was removed.

  • Various impossible Error associated types are now set to !.

  • All AdHoc constructors require a name as the first parameter.

  • The top-level Error type was removed.

  • Launch failures (LaunchError) from Rocket::launch() are now returned for inspection without panicking.
  • Routes without query parameters now match requests with or without query parameters.
  • Default rankings range from -4 to -1, preferring static paths and routes with query string matches.
  • A native Accept header structure was added.
  • The Accept request header can be retrieved via Request::accept().
  • Incoming form fields can be renamed via a new #[form(field = "name")] structure field attribute.
  • All active routes can be retrieved via Rocket::routes().
  • Response::body_string() was added to retrieve the response body as a String.
  • Response::body_bytes() was added to retrieve the response body as a Vec<u8>.
  • Response::content_type() was added to easily retrieve the Content-Type header of a response.
  • Size limits on incoming data are now configurable.
  • Request::limits() was added to retrieve incoming data limits.
  • Responders may dynamically adjust their response based on the incoming request.
  • Request::guard() was added for simple retrieval of request guards.
  • Request::route() was added to retrieve the active route, if any.

Breaking Changes

This release includes many breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications.

  • session_key was renamed to secret_key, requires a 256-bit base64 key

    It's unlikely that session_key was previously used. If it was, rename session_key to secret_key. Generate a random 256-bit base64 key using a tool like openssl: openssl rand -base64 32.

  • The &Cookies request guard has been removed in favor of Cookies

    Change &Cookies in a request guard position to Cookies.

  • Rocket::launch() now returns a LaunchError, doesn't panic.

    For the old behavior, suffix a call to .launch() with a semicolon: .launch();.

  • Routes without query parameters match requests with or without query parameters.

    There is no workaround, but this change may allow manual ranks from routes to be removed.

  • The format route attribute on non-payload requests matches against the Accept header.

    Excepting a custom request guard, there is no workaround. Previously, format always matched against the Content-Type header, regardless of whether the request method indicated a payload or not.

  • A type of &str can no longer be used in form structures or parameters.

    Use the new &RawStr type instead.

  • ContentType is no longer a request guard.

    Use &ContentType instead.

  • Request::content_type() returns &ContentType instead of ContentType.

    Use .clone() on &ContentType if a type of ContentType is required.

  • Response::header_values() was removed. Response::headers() now returns an &HeaderMap.

    A call to Response::headers() can be replaced with Response::headers().iter(). A call to Response::header_values(name) can be replaced with Response::headers().get(name).

  • Route collisions result in a hard error and panic.

    There is no workaround. Previously, route collisions were a warning.

  • The IntoOutcome trait has been expanded and made more flexible.

    There is no workaround. IntoOutcome::into_outcome() now takes a Failure value to use. IntoOutcome::or_forward() was added to return a Forward outcome if self indicates an error.

  • The 'testing' feature was removed.

    Remove features = ["testing"] from Cargo.toml. Use the new local module for testing.

  • serde was updated to 1.0.

    There is no workaround. Ensure all dependencies rely on serde 1.0.

  • config::active() was removed.

    Use Rocket::config() to retrieve the configuration before launch. If needed, use managed state to store config information for later use.

  • The Responder trait has changed.

    Responder::respond(self) was removed in favor of Responder::respond_to(self, &Request). Responders may dynamically adjust their response based on the incoming request.

  • Outcome::of(Responder) was removed while Outcome::from(&Request, Responder) was added.

    Use Outcome::from(..) instead of Outcome::of(..).

  • Usage of templates requires Template::fairing() to be attached.

    Call .attach(Template::fairing()) on the application's Rocket instance before launching.

  • The Display implementation of Template was removed.

    Use Template::show() to render a template directly.

  • Request::new() is no longer exported.

    There is no workaround.

  • The FromForm trait has changed.

    Responder::from_form_items(&mut FormItems) was removed in favor of Responder::from_form(&mut FormItems, bool). The second parameter indicates whether parsing should be strict (if true) or lenient (if false).

  • LoggingLevel was removed as a root reexport.

    It can now be imported from rocket::config::LoggingLevel.

  • An Io variant was added to ConfigError.

    Ensure matches on ConfigError include an Io variant.

  • ContentType::from_extension() returns an Option<ContentType>.

    For the old behvavior, use .unwrap_or(ContentType::Any).

  • The IntoValue config trait was removed in favor of Into<Value>.

    There is no workaround. Use Into<Value> as necessary.

  • The rocket_contrib::JSON type has been renamed to rocket_contrib::Json.

    Use Json instead of JSON.

  • All structs in the content module use TitleCase names.

    Use Json, Xml, Html, and Css instead of JSON, XML, HTML, and CSS, respectively.

In addition to new features, Rocket saw the following improvements:

  • "Rocket" is now capatilized in the Server HTTP header.
  • The generic parameter of rocket_contrib::Json defaults to json::Value.

  • Added the ability to set configuration parameters via environment variables.
  • Config structures can be built via ConfigBuilder, which follows the builder pattern.
  • Logging can be enabled or disabled on custom configuration via a second parameter to the Rocket::custom method.
  • name and value methods were added to Header to retrieve the name and value of a header.

  • The SocketAddr request guard retrieves the remote address.
  • A UUID type has been added to contrib.

  • Major performance and usability improvements were upstreamed to the cookie crate, including the addition of a CookieBuilder.
  • When a checkbox isn't present in a form, bool types in a FromForm structure will parse as false.
  • The FormItems iterator can be queried for a complete parse via completed and exhausted.
  • Routes for OPTIONS requests can be declared via the options decorator.
  • Strings can be percent-encoded via URI::percent_encode().

Breaking Changes

This release includes several breaking changes. These changes are listed below along with a short note about how to handle the breaking change in existing applications.

  • Rocket::custom takes two parameters, the first being Config by value.

    A call in v0.1 of the form Rocket::custom(&config) is now Rocket::custom(config, false).

  • Tera templates are named without their extension.

    A templated named name.html.tera is now simply name.

  • JSON unwrap method has been renamed to into_inner.

    A call to .unwrap() should be changed to .into_inner().

  • The map! macro was removed in favor of the json! macro.

    A call of the form map!{ "a" => b } can be written as: json!({ "a": b }).

  • The hyper::SetCookie header is no longer exported.

    Use the Cookie type as an Into<Header> type directly.

  • The Content-Type for String is now text/plain.

    Use content::HTML<String> for HTML-based String responses.

  • Request.content_type() returns an Option<ContentType>.

    Use .unwrap_or(ContentType::Any) to get the old behavior.

  • The ContentType request guard forwards when the request has no Content-Type header.

    Use an Option<ContentType> and .unwrap_or(ContentType::Any) for the old behavior.

  • A Rocket instance must be declared before a MockRequest.

    Change the order of the rocket::ignite() and MockRequest::new() calls.

  • A route with format specified only matches requests with the same format.

    Previously, a route with a format would match requests without a format specified. There is no workaround to this change; simply specify formats when required.

  • FormItems can no longer be constructed directly.

    Instead of constructing as FormItems(string), construct as FormItems::from(string).

  • from_from_string(&str) in FromForm removed in favor of from_form_items(&mut FormItems).

    Most implementation should be using FormItems internally; simply use the passed in FormItems. In other cases, the form string can be retrieved via the inner_str method of FormItems.

  • Config::{set, default_for} are deprecated.

    Use the set_{param} methods instead of set, and new or build in place of default_for.

  • Route paths must be absolute.

    Prepend a / to convert a relative path into an absolute one.

  • Route paths cannot contain empty segments.

    Remove any empty segments, including trailing ones, from a route path.

Bug Fixes

A couple of bugs were fixed in this release:

  • Handlebars partials were not properly registered (#122).
  • Rocket::custom did not set the custom configuration as the active configuration.
