Fixes #1679.

Sergio Benitez 6a3d1ac1d5 Fix 'UriDisplay<Query>' 'Json', 'MsgPack', impls.
As 'FromForm' doesn't provide access to the raw, undecoded string,
'MsgPack' cannot implement 'FromForm::from_value()'. This means that it
is not presently possible to parse a MessagePack form from a query
string. As such, the 'UriDisplay<Query>' implementation was removed.

The 'UriDisplay<Query>' for JSON was fixed such that a round-trip of a
'Json<T>' as a form works as expected.

Sergio Benitez 9957e00ad1 Pass type mapper directly in 'Responder' derive. 2021-06-30 06:46:03 -07:00
Sergio Benitez 01a11800ab Support all generics in 'UriDisplay' derive.
This ports the technique used for 'FromForm' and 'Responder' to the
'UriDisplay' trait derives.

Sergio Benitez 793f421712 Support type generics, unit structs in 'FromForm'.
The 'FromFrom' derive now allows type generics in all positions using
the same automatic discovery technique as with 'Responder'. (In fact,
the technique was created for this derive.) Furthermore, 'FromForm' can
now be derived for unit structs.

Also adds a new 'try_with' form field validator.

Resolves #1695.

Sergio Benitez 2727d7bb7b Automatically discover 'Responder' generic bounds.
This commit presents and applies a new technique for bounding type
generics in derives. In short, for a generic `T` used in a field type of
`Field<T>`, where an eventual bound of `Responder` required, the derive
generates a bound of `Field<T>: Responder`. This removes the need for
any manually provided bounds while simultaneously allowing more
structures to typecheck. For example, generics in header components are
now fully supported.

Sergio Benitez b00c89c22f Support lifetime bounds in typed stream macros.
The syntax 'TypedStream![T + '_]' expands to:

  impl TypedStream<Item = T> + '_

This allows seamlessly borrowing in typed streams.

Also adds 'Event::empty()', for convenience.

Sergio Benitez 9063cf0ac2 Visiting internal nodes in form field validator.
Previously, recursion into rewriting 'self' in field validations would
cease after the first function call. This meant that internal uses of
'self' were not properly rewritten. This commit ameliorates the
situation.

Sergio Benitez 4c6562cd29 Drop 'Data' after sending a response, not before.
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.

Sergio Benitez ed3cc13b84 Add internal '__typed_stream' proc-macro.
This resolves syntax ambiguity issues with public typed-stream macros.
Prior to this commit, greedy single-token matching by macro-rules macros
would result in certain tokens at the beginning of the macro input, such
as 'for', inadvertently triggering a '$ty' matching case resulting in
incorrect expansion.

Sergio Benitez fa3e0334c1 Overhaul URI types, parsers, 'uri!' macro.
This commit entirely rewrites Rocket's URI parsing routines and
overhauls the 'uri!' macro resolving all known issues and removing any
potential limitations for compile-time URI creation. This commit:

  * Introduces a new 'Reference' URI variant for URI-references.
  * Modifies 'Redirect' to accept 'TryFrom<Reference>'.
  * Introduces a new 'Asterisk' URI variant for parity.
  * Allows creation of any URI type from a string literal via 'uri!'.
  * Enables dynamic/static prefixing/suffixing of route URIs in 'uri!'.
  * Unifies 'Segments' and 'QuerySegments' into one generic 'Segments'.
  * Consolidates URI formatting types/traits into a 'uri::fmt' module.
  * Makes APIs more symmetric across URI types.

It also includes the following less-relevant changes:

  * Implements 'FromParam' for a single-segment 'PathBuf'.
  * Adds 'FileName::is_safe()'.
  * No longer reparses upstream request URIs.

Sergio Benitez d03a07b183 Retrieve managed state via a borrow: '&State<T>'.
This has the following positive effects:

  1) The lifetime retrieved through 'Deref' is now long-lived.
  2) An '&State<T>` can be created via an '&T'.
  3) '&State<T>' is shorter to type than 'State<'_, T>'.

Sergio Benitez 63e6845386 Revamp 'Response', 'Body' types.
This is a breaking change for many consumers of the 'Response' and all
consumers of the 'Body' API. The summary of breaking changes is:

  * 'Response::body()', 'Response::body_mut()' are infallible.
  * A 'Body' can represent an empty body in more cases.
  * 'ResponseBuilder' is now simply 'Builder'.
  * Direct body read methods on 'Response' were removed in favor of
    chaining through 'body_mut()': 'r.body_mut().to_string()'.
  * Notion of a 'chunked_body' was removed as it was inaccurate.
  * Maximum chunk size can be set on any body.
  * 'Response' no longer implements 'Responder'.

A few bugs were fixed in the process. Specifically, 'Body' will emit an
accurate size even for bodies that are partially read, and the size of
seek-determined bodies is emitted on HEAD request where it wasn't
before. Specifics on transport were clarified, and 'Body' docs greatly
improved as a result.

Sergio Benitez bab3b1cb5b Mod-export 'msg!', 'local_cache!', 'try_outcome!'.
This removes the export of each of these macros from the root, limiting
their export-scope to their respective module. This is accomplished
using a new internal macro, 'export!', which does some "magic" to work
around rustdoc deficiencies.

Matthew Pomes d4466b73af Fix codegen so rustc emits unused route warnings.
Changes codegen to use an instance method on the route proxy struct
rather than implementing a trait on the proxy struct. This helps rustc
identify unused routes.

Sergio Benitez 801e04bd53 Log guard failures, potential misuses.
This commit includes changes that improve how and what Rocket logs
automatically. Rocket now logs:

  * All guard errors, indicating the failing guard kind and type.
  * A warning when a 'TempFile' is used as a data guard for a request
    that specifies a 'form' Content-Type.
  * Only the top/sub of a request's format.

This commit makes the following breaking changes:

  * '<T as FromData>::Error' must implement 'Debug'.

Furthermore, this commit restores the previous behavior of always
logging launch info. It further restores the unspecified behavior of
modifying logging state only when the set logger is Rocket's logger.

Antoine Martin f6749e1b44 Fix misspelled link in '#[route]' attribute docs. 2021-04-20 17:26:08 -07:00
Sergio Benitez 64e46b7107 Introduce sentinels: auto-discovered launch abort.
Sentinels resolve a long-standing usability and functional correctness
issue in Rocket: starting an application with guards and/or responders
that depend on state that isn't available. The canonical example is the
'State' guard. Prior to this commit, an application with routes that
queried unmanaged state via 'State' would fail at runtime. With this
commit, the application refuses to launch with a detailed error message.

The 'Sentinel' docs explains it as:

    A sentinel, automatically run on ignition, can trigger a launch
    abort should an instance fail to meet arbitrary conditions. Every
    type that appears in a mounted route's type signature is eligible to
    be a sentinel. Of these, those that implement 'Sentinel' have their
    'abort()' method invoked automatically, immediately after ignition,
    once for each unique type. Sentinels inspect the finalized instance
    of 'Rocket' and can trigger a launch abort by returning 'true'.

The following types are now sentinels:

  * 'contrib::databases::Connection' (any '#[database]' type)
  * 'contrib::templates::Metadata'
  * 'contrib::templates::Template'
  * 'core::State'

The following are "specialized" sentinels, which allow sentinel
discovery even through type aliases:

  * 'Option<T>', 'Debug<T>' if 'T: Sentinel'
  * 'Result<T, E>', 'Either<T, E>' if 'T: Sentinel', 'E: Sentinel'

Closes #464.
