Prior to this commit, all forward outcomes resulted in a 404. This
commit changes request and data guards so that they are able to provide
a `Status` on `Forward` outcomes. The router uses this status, if the
final outcome is to forward, to identify the catcher to invoke.
The net effect is that guards can now customize the status code of a
forward and thus the error catcher invoked if the final outcome of a
request is to forward.
Resolves#1560.
Tungstenite abuses `Err(ConnectionClosed)` to indicate the non-error
condition of a websocket closing. This commit changes error processing
such that the error is caught and converted into a successful
termination of websocket handling.
This is a two-prong effort. First, we warn on launch if a known key is
used. Second, we document using invalid keys where possible.

Adds an `ip_header` configuration parameter that allows modifying the
header Rocket attempts to use to retrieve the "real IP" address of the
client via `Request` methods like `client_ip()`. Additionally allows
disabling the use of any such header.
Previously, the heartbeat message, in its raw form, was ":\n\n". This
commit changes the message to be ":\n".
The former message, when parsed as Server-Sent Events, contained an
empty comment (as desired) _and_ a new line (erroneously). The new line
resulted in emitting any event that was presently being emitted, even if
it wasn't complete. That is, emitting an event partly, such as the
event's data but not its name. Removing the extra new line resolves this
issue and ensures that events aren't interrupted by the heartbeat.
Fixes#2152.
The primary aim of this commit is to reduce confusion between
'content::Json' and 'rocket::serde::json::Json' be renaming the former
to 'content::RawJson'. The complete changes in this PR are:
* All responders in the 'content' module are prefixed with 'Raw'.
* The 'content::Custom' responder was removed entirely.
* The 'Plain' responder is now 'RawText'.
* The 'content' API docs point to the 'serde' responders.
* The docs and examples were updated accordingly.
This is the async analog of 'rocket_sync_db_pools', rewritten to be
cleaner, leaner, easier to maintain and extend, and better documented.
Resolves#1117.
Resolves#1187.
The 'Json' type now implements:
* Clone
* PartialEq
* Eq
* PartialOrd
* Ord
* Hash
* UriDisplay<Query>
Method calls that resolve to a method in the set of traits above
previously resolved to the `Deref` target. For example, `foo.clone()`,
where `foo: Json<T>`, previously resolved to `<T as Clone>::clone()` but
now resolves to `<Json<T> as Clone>::clone()`.
This allows responses to be sent to the client even when data is only
partially read, significantly improving the experience for the client
from one with a "connection closed" error to one with a proper response.
The consequence is a lifetime in 'Data'.
Though other non-lifetime-introducing solutions exist, the introduction
of a lifetime to 'Data' is a longstanding desire as it prevents
smuggling 'Data' into a longer-lived context. Use of 'Data' in that
context was unspecified with various runtime consequences. The addition
of a lifetime bound by the request prevents this error statically.
In summary, the changes are:
* Clients receive responses even when data isn't fully read.
* 'Data' becomes 'Data<'r>'. 'FromData' changes accordingly.
* Route 'Outcome's are strictly tied to the request lifetime.
Tangentially, the invalid length form field validation error message has
improved to format length in byte units if it exceeds 1024.
This follows the completed graduation of stable contrib features into
core, removing 'rocket_contrib' in its entirety in favor of two new
crates. These crates are versioned independently of Rocket's core
libraries, allowing upgrades to dependencies without consideration for
versions in core libraries.
'rocket_dyn_templates' replaces the contrib 'templates' features. While
largely a 1-to-1 copy, it makes the following changes:
* the 'tera_templates' feature is now 'tera'
* the 'handlebars_templates' feature is now 'handlebars'
* fails to compile if neither 'tera' nor 'handlebars' is enabled
'rocket_sync_db_pools' replaces the contrib 'database' features. It
makes no changes to the replaced features except that the `database`
attribute is properly documented at the crate root.
