CHANGELOG.md

Version 0.2.1 (Feb 24, 2017)

Core Fixes

• Flash cookie deletion functions as expected regardless of the path.
• config properly accepts IPv6 addresses.
• Multiple Set-Cookie headers are properly set.

Core Improvements

• Display and Error were implemented for ConfigError.
• webp, ttf, otf, woff, and woff2 were added as known content types.
• Routes are presorted for faster routing.
• into_bytes and into_inner methods were added to Body.

Codegen

• Fixed unmanaged_state lint so that it works with prefilled type aliases.

Contrib

• Better errors are emitted on Tera template parse errors.

Documentation

• Fixed typos in manage and JSON docs.

Infrastructure

• Updated doctests for latest Cargo nightly.

Version 0.2.0 (Feb 06, 2017)

Detailed release notes for v0.2 can also be found on rocket.rs.

New Features

This release includes the following new features:

• Introduced managed state.
• Added lints that warn on unmanaged state and unmounted routes.
• 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.
• A new configuration parameter, workers, can be used to set the number of threads Rocket uses.
• The address of the remote connection is available via Request.remote(). Request preprocessing overrides remote IP with value from the X-Real-IP header, if present.
• During testing, the remote address can be set via MockRequest.remote().
• The SocketAddr request guard retrieves the remote address.
• A UUID type has been added to contrib.
• rocket and rocket_codegen will refuse to build with an incompatible nightly version and emit nice error messages.
• 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.
• Route path segments containing more than one dynamic parameter were allowed.
