Sergio Benitez fda05bddd2 Update 'rustls' to 0.20.
Also updates 'tokio-rustls' to a compatible version.

Additionally depends on 'rustls-pemfile' which includes functionality
that was previously part of 'rustls' itself.

arlecchino 1ba41b3990 Remove 'CookieJar::get_private_pending()'.
This commit removes the 'CookieJar::get_private_pending()' method in
favor of the already existing and correct 'CookieJar::get_pending()'
method. Previously, the 'CookieJar::get_private_pending()' method
attempted to decrypt the value of a pending cookie, which in reality is
plaintext, thus failing. Because the pending value is plaintext, the
'CookieJar::get_pending()' method suffices.

Documentation has been updated to refer to 'CookieJar::get_pending()'.

Fixes #2063.

Sergio Benitez cc0621626b Prefix 'content' responder names with 'Raw'.
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.

Sergio Benitez 614f8ab46c Condition TLS config types on 'tls' feature.

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 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.

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()`.

2021-06-08 23:00:59 -07:00
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 7595450adc Use published 'state'. 2021-06-07 20:34:27 -07:00
Sergio Benitez 333da45470 Allow non-breaking config additions.
If stars aligned properly, we might imagine writing this:

    #[non_exhaustive]
    struct Config {
        pub field: Foo,
        pub other: Bar,
    }

...with semantics that would allow the defining crate (here, Rocket), to
construct the structure directly while consumers would need to use
public constructors or struct update syntax:

    Config {
        field: Foo,
        other: Bar,
        ..Default::default()
    }

Alas, this is not the way `non_exhaustive` works on structs. You cannot
use field-update syntax to construct `Config` above. You must use public
constructors. This means builder methods or mutating an already built
struct. This is not what we want.

I don't know why it works this way. I don't see why it must. Something
something Drop.

So we have this hack from the pre-non_exhaustive era.

Sergio Benitez 009be32a8c Improve request conversion performance, semantics.
This commit makes the following improvements to core request handling:

  * Absolute target URIs are not rejected. Instead, the path and query
    parts are passed through the application. This resolves an issue
    where certain HTTP/2 requests would be rejected by Rocket.
  * Data is never copied from the request. Previously, Rocket would copy
    and allocate for incoming headers.
  * Non-UTF-8 headers are dropped with a warning instead of being
    lossily, and thus perhaps incorrectly, decoded as UTF-8. The final
    fix is to properly support non-UTF-8 headers, no matter how in the
    minority they are.

Sergio Benitez 5a4e66ec43 Split 'rocket_contrib' into distinct crates.
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.

Sergio Benitez a78814f1c5 Graduate contrib 'uuid' into core.
This has the following nice benefits:

  * The 'Uuid' wrapper type is gone.
  * 'Uuid' implements 'UriDisplay', 'FromUriParam'.
  * The 'serialization' example merges in 'uuid'.

Resolves #1299.

Sergio Benitez f6a7087c84 Graduate 'helmet' as 'shield' into core.
The 'SpaceHelmet' fairing is now called 'Shield'. It features the
following changes and improvements:

  * Headers which are now ignored by browsers are removed.
  * 'XssFilter' is no longer an on-by-default policy.
  * A new 'Permission' policy is introduced.
  * 'Shield' is attached to all 'Rocket' instances by default.
  * Default headers never allocate on 'Clone'.
  * Policy headers are rendered once and cached at start-up.
  * Improved use of typed URIs in policy types.

Sergio Benitez 267cb9396f Introduce 'Singleton' fairings.
A singleton fairing is guaranteed to be the only instance of its type at
launch time. If more than one instance of a singleton fairing is
attached, only the last instance is retained.

Sergio Benitez 824edef3fc Prevent double-panic on 'Error' drop.
Previously, if a panic occurred with an 'Error' on the stack, 'Error'
would panic as usual during unwinding. This resulted in a double panic.
This commit makes 'Error' detect if a panic is already occurring and
omits its own panic if it is.

Sergio Benitez c74bcfd40a Graduate contrib 'json' and 'msgpack' into core.
This has the following nice benefits:

  * The 'JsonValue' wrapper type is gone.
  * 'Local{Request, Response}' natively support JSON/MessagePack.
  * The 'json' and 'msgpack' limits are officially recognized.
  * Soon, Rocket application will not require an explicit 'serde' dep.

This marks the beginning of the end of 'rocket_contrib'.

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.

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 a72e8da735 Implement graceful shutdown.
The crux of the implementation is as follows:

  * Configurable ctrl-c, signals that trigger a graceful shutdown.
  * Configurable grace period before forced I/O termination.
  * Programatic triggering via an application-wide method.
  * A future (`Shutdown`) that resolves only when shutdown is requested.

Resolves #180.

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.

Sergio Benitez d21608ca7b Remove 'Content' in favor of 'content::Custom'.

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.

Sergio Benitez 08c0701bdc Clarify internal sentinel docs. 2021-04-23 19:19:39 -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.

Sergio Benitez 4f3511786c Introduce statically-enforced 'Rocket' phasing.
The core 'Rocket' type is parameterized: 'Rocket<P: Phase>', where
'Phase' is a newly introduced, sealed marker trait. The trait is
implemented by three new marker types representing the three launch
phases: 'Build', 'Ignite', and 'Orbit'. Progression through these three
phases, in order, is enforced, as are the invariants guaranteed by each
phase. In particular, an instance of 'Rocket' is guaranteed to be in its
final configuration after the 'Build' phase and represent a running
local or public server in the 'Orbit' phase. The 'Ignite' phase serves
as an intermediate, enabling inspection of a finalized but stationary
instance. Transition between phases validates the invariants required
by the transition.

All APIs have been adjusted appropriately, requiring either an instance
of 'Rocket' in a particular phase ('Rocket<Build>', 'Rocket<Ignite>', or
'Rocket<Orbit>') or operating generically on a 'Rocket<P>'.
Documentation is also updated and substantially improved to mention
required and guaranteed invariants.

Additionally, this commit makes the following relevant changes:

  * 'Rocket::ignite()' is now a public interface.
  * 'Rocket::{build,custom}' methods can no longer panic.
  * 'Launch' fairings are now 'ignite' fairings.
  * 'Liftoff' fairings are always run, even in local mode.
  * All 'ignite' fairings run concurrently at ignition.
  * Launch logging occurs on launch, not any point prior.
  * Launch log messages have improved formatting.
  * A new launch error kind, 'Config', was added.
  * A 'fairing::Result' type alias was introduced.
  * 'Shutdown::shutdown()' is now 'Shutdown::notify()'.

Some internal changes were also introduced:

  * Fairing 'Info' name for 'Templates' is now 'Templating'.
  * Shutdown is implemented using 'tokio::sync::Notify'.
  * 'Client::debug()' is used nearly universally in tests.
