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 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 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.
2021-05-22 11:01:00 -07:00
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.

Resolves #842.

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 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

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 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.

Sergio Benitez 0bdb6b7bc7 Remove 'attach' fairings. Add 'liftoff' fairings.
Launch fairings are now fallible and take the place of attach fairings,
but they are only run, as the name implies, at launch time.

This is is a fundamental shift from eager execution of set-up routines,
including the now defunct attach fairings, to lazy execution,
precipitated by the transition to `async`. The previous functionality,
while simple, caused grave issues:

  1. A instance of 'Rocket' with async attach fairings requires an async
     runtime to be constructed.
  2. The instance is accessible in non-async contexts.
  3. The async attach fairings have no runtime in which to be run.

Here's an example:

```rust
let rocket = rocket::ignite()
    .attach(AttachFairing::from(|rocket| async {
        Ok(rocket.manage(load_from_network::<T>().await))
    }));

let state = rocket.state::<T>();
```

This had no real meaning previously yet was accepted by running the
attach fairing future in an isolated runtime. In isolation, this causes
no issue, but when attach fairing futures share reactor state with other
futures in Rocket, panics ensue.

The new Rocket application lifecycle is this:

  * Build - A Rocket instance is constructed. No fairings are run.
  * Ignition - All launch fairings are run.
  * Liftoff - If all launch fairings succeeded, the server is started.

New 'liftoff' fairings are run in this third phase.
2021-04-07 23:09:00 -07:00
Sergio Benitez 2893ce754d Introduce scoped catchers.
Catchers can now be scoped to paths, with preference given to the
longest-prefix, then the status code. This a breaking change for all
applications that register catchers:

  * `Rocket::register()` takes a base path to scope catchers under.
    - The previous behavior is recovered with `::register("/", ...)`.
  * Catchers now fallibly, instead of silently, collide.
  * `ErrorKind::Collision` is now `ErrorKind::Collisions`.

Related changes:

  * `Origin` implements `TryFrom<String>`, `TryFrom<&str>`.
  * All URI variants implement `TryFrom<Uri>`.
  * Added `Segments::prefix_of()`.
  * `Rocket::mount()` takes a  `TryInto<Origin<'_>>` instead of `&str`
    for the base mount point.
  * Extended `errors` example with scoped catchers.
  * Added scoped sections to catchers guide.

Internal changes:

  * Moved router code to `router/router.rs`.

  * For example, '/' now collides with '/<p..>'.

  * For example, request '/' matches route '/<p..>'.

Sergio Benitez 63a14525d8 UTF-8 routes. Forms revamp. Temp files. Capped.
So. Many. Changes.

This is an insane commit: simultaneously one of the best (because of all
the wonderful improvements!) and one of the worst (because it is just
massive) in the project's history.

Routing:
  * All UTF-8 characters are accepted everywhere in route paths. (#998)
  * `path` is now `uri` in `route` attribute: `#[route(GET, path = "..")]`
    becomes `#[route(GET, uri = "..")]`.

Forms Revamp
  * All form related types now reside in a new `form` module.
  * Multipart forms are supported. (resolves #106)
  * Collections are supported in forms and queries. (resolves #205)
  * Nested structures in forms and queries are supported. (resolves #313)
  * Form fields can be ad-hoc validated with `#[field(validate = expr)]`.
  * `FromFormValue` is now `FromFormField`, blanket implements `FromForm`.
  * Form field values are always percent-decoded apriori.

Temporary Files
  * A new `TempFile` data and form guard allows streaming data directly to a
    file which can then be persisted.
  * A new `temp_dir` config parameter specifies where to store `TempFile`.
  * The limits `file` and `file/$ext`, where `$ext` is the file extension,
    determines the data limit for a `TempFile`.

Capped
  * A new `Capped` type is used to indicate when data has been truncated due to
    incoming data limits. It allows checking whether data is complete or
    truncated.
  * `DataStream` methods return `Capped` types.
  * `DataStream` API has been revamped to account for `Capped` types.
  * Several `Capped<T>` types implement `FromData`, `FromForm`.
  * HTTP 413 (Payload Too Large) errors are now returned when data limits are
    exceeded. (resolves #972)

Hierarchical Limits
  * Data limits are now hierarchical, delimited with `/`. A limit of `a/b/c`
    falls back to `a/b` then `a`.

Core
  * `&RawStr` no longer implements `FromParam`.
  * `&str` implements `FromParam`, `FromData`, `FromForm`.
  * `FromTransformedData` was removed.
  * `FromData` gained a lifetime for use with request-local data.
  * The default error HTML is more compact.
  * `&Config` is a request guard.
  * The `DataStream` interface was entirely revamped.
  * `State` is only exported via `rocket::State`.
  * A `request::local_cache!()` macro was added for storing values in
    request-local cache without consideration for type uniqueness by using a
    locally generated anonymous type.
  * `Request::get_param()` is now `Request::param()`.
  * `Request::get_segments()` is now `Request::segments()`, takes a range.
  * `Request::get_query_value()` is now `Request::query_value()`, can parse any
    `FromForm` including sequences.
  * `std::io::Error` implements `Responder` like `Debug<std::io::Error>`.
  * `(Status, R)` where `R: Responder` implements `Responder` by overriding the
    `Status` of `R`.
  * The name of a route is printed first during route matching.
  * `FlashMessage` now only has one lifetime generic.

HTTP
  * `RawStr` implements `serde::{Serialize, Deserialize}`.
  * `RawStr` implements _many_ more methods, in particular, those related to the
    `Pattern` API.
  * `RawStr::from_str()` is now `RawStr::new()`.
  * `RawStr::url_decode()` and `RawStr::url_decode_lossy()` only allocate as
    necessary, return `Cow`.
  * `Status` implements `Default` with `Status::Ok`.
  * `Status` implements `PartialEq`, `Eq`, `Hash`, `PartialOrd`, `Ord`.
  * Authority and origin part of `Absolute` can be modified with new
    `Absolute::{with,set}_authority()`, `Absolute::{with,set}_origin()` methods.
  * `Origin::segments()` was removed in favor of methods split into query and
    path parts and into raw and decoded versions.
  * The `Segments` iterator is smarter, returns decoded `&str` items.
  * `Segments::into_path_buf()` is now `Segments::to_path_buf()`.
  * A new `QuerySegments` is the analogous query segment iterator.
  * Once set, `expires` on private cookies is not overwritten. (resolves #1506)
  * `Origin::path()` and `Origin::query()` return `&RawStr`, not `&str`.

Codegen
  * Preserve more spans in `uri!` macro.
  * Preserve spans `FromForm` field types.
  * All dynamic parameters in a query string must typecheck as `FromForm`.
  * `FromFormValue` derive removed; `FromFormField` added.
  * The `form` `FromForm` and `FromFormField` field attribute is now named
    `field`. `#[form(field = ..)]` is now `#[field(name = ..)]`.

Contrib
  * `Json` implements `FromForm`.
  * `MsgPack` implements `FromForm`.
  * The `json!` macro is exported as `rocket_contrib::json::json!`.
  * Added clarifying docs to `StaticFiles`.

Examples
  * `form_validation` and `form_kitchen_sink` removed in favor of `forms`.
  * The `hello_world` example uses unicode in paths.
  * The `json` example only allocates as necessary.

Internal
  * Codegen uses new `exports` module with the following conventions:
    - Locals starts with `__` and are lowercased.
    - Rocket modules start with `_` and are lowercased.
    - `std` types start with `_` and are titlecased.
    - Rocket types are titlecased.
  * A `header` module was added to `http`, contains header types.
  * `SAFETY` is used as doc-string keyword for `unsafe` related comments.
  * The `Uri` parser no longer recognizes Rocket route URIs.

Sergio Benitez 1fb061496d Revamp configuration.
This commit completely overhauls Rocket's configuration systems, basing
it on the new Figment library. It includes many breaking changes
pertaining to configuration. They are:

  * "Environments" are replaced by "profiles".
  * 'ROCKET_PROFILE' takes the place of 'ROCKET_ENV'.
  * Profile names are now arbitrary, but 'debug' and 'release' are given
    special treatment as default profiles for the debug and release
    compilation profiles.
  * A 'default' profile now sits along-side the meta 'global' profile.
  * The concept of "extras" is no longer present; users can extract any
    values they want from the configured 'Figment'.
  * The 'Poolable' trait takes an '&Config'.
  * The 'secrets' feature is disabled by default.
  * It is a hard error if 'secrets' is enabled under the 'release'
    profile and no 'secret_key' is configured.
  * 'ConfigBuilder' no longer exists: all fields of 'Config' are public
    with public constructors for each type.
  * 'keep_alive' is disabled with '0', not 'false' or 'off'.
  * Inlined error variants into the 'Error' structure.
  * 'LoggingLevel' is now 'LogLevel'.
  * Limits can now be specified in SI units: "1 MiB".

The summary of other changes are:

  * The default config file can be configured with 'ROCKET_CONFIG'.
  * HTTP/1 and HTTP/2 keep-alive configuration is restored.
  * 'ctrlc' is now a recognized config option.
  * 'serde' is now a core dependency.
  * TLS misconfiguration errors are improved.
  * Several example use '_' as the return type of '#[launch]' fns.
  * 'AdHoc::config()' was added for simple config extraction.
  * Added more documentation for using 'Limits'.
  * Launch information is no longer treated specially.
  * The configuration guide was rewritten.

Sergio Benitez 5d9035ddc1 Keep an op-log for sync 'CookieJar'.
In brief, this commit:

  * Updates to the latest upstream 'cookie', fixing a memory leak.
  * Make changes to 'CookieJar' observable only through 'pending()'.
  * Deprecates 'Client::new()' in favor of 'Client::tracked()'.
  * Makes 'dispatch()' on tracked 'Client's synchronize on cookies.
  * Makes 'Client::untracked()' actually untracked.

This commit updates to the latest 'cookie' which removes support for
'Sync' cookie jars. Instead of relying on 'cookie', this commit
implements an op-log based 'CookieJar' which internally keeps track of
changes. The API is such that changes are only observable through
specialized '_pending()' methods.

Sergio Benitez dee11966b6 Borrow 'self' in 'Connection::run()'.
This simulates the pre-async behavior of serialization attempts to use a
connection by using an `async` Mutex.
2020-09-10 03:34:26 -07:00
Jeb Rosen bc8c5b9ee2 Use 'spawn_blocking' in '#[database]'.
The connection guard type generated by `#[database]` no longer
implements `Deref` and `DerefMut`. Instead, it provides an `async fn
run()` that gives access to the underlying connection on a closure run
through `spawn_blocking()`.

Additionally moves most of the implementation of `#[database]` out
of generated code and into library code for better type-checking.
2020-09-10 03:34:26 -07:00
Sergio Benitez 52320020bc Use thread-safe 'CookieJar's.
The user-facing changes effected by this commit are:

  * The 'http::Cookies<'_>' guard is now '&http::CookieJar<'_>'.
  * The "one-at-a-time" jar restriction is no longer imposed.
  * 'CookieJar' retrieval methods return 'http::CookieCrumb'.
  * The 'private-cookies' feature is now called 'secrets'.
  * Docs flag private cookie methods with feature cfg.
  * Local, async request dispatching is never serialized.
  * 'Client::cookies()' returns the tracked 'CookieJar'.
  * 'LocalResponse::cookies()' returns a 'CookieJar'.
  * 'Response::cookies()' returns an 'impl Iterator'.
  * A path of '/' is set by default on all cookies.
  * 'SameSite=strict' is set by default on all cookies.
  * 'LocalRequest::cookies()' accepts any 'Cookie' iterator.
  * The 'Debug' impl for 'Request' prints the cookie jar.

Resolves #1332.

Closes #1325.

Sergio Benitez 45b4436ed3 Add default catchers: '#[catch(default)]'.
The bulk of the changes in this commit are for creating an
'ErrorHandler' trait that works like the 'Handler' trait, but for
errors. Furthermore, Rocket's default catcher now responds with a JSON
payload if the preferred 'Accept' media type is JSON.

This commit also fixes a bug in 'LocalRequest' where the internal
'Request' contained an correct 'URI'.

Sergio Benitez adc79016cd Rearrange top-level exports. Use '#[launch]'.
This commits makes the following high-level changes:

  * 'ShutdownHandle' is renamed to 'Shutdown'.
  * 'Rocket::shutdown_handle()' is renamed to 'Rocket::shutdown()'.
  * '#[launch]` is preferred to '#[rocket::launch]'.
  * Various docs phrasings are improved.
  * Fixed various broken links in docs.

This commits rearranges top-level exports as follows:

  * 'shutdown' module is no longer exported.
  * 'Shutdown' is exported from the crate root.
  * 'Outcome' is not longer exported from the root.
  * 'Handler', 'ErrorHandler' are no longer exported from the root.

Sergio Benitez 6482fa2fba Rework 'local' module. Add 'LocalResponse' methods.
This completes the 'local' blocking client implementation.
2020-07-11 09:24:30 -07:00
Sergio Benitez 03127f4dae Add blocking variant of 'local'.
This commit adds the 'local::blocking' module and moves the existing
asynchronous testing to 'local::asynchronous'. It also includes several
changes to improve the local API, bringing it to parity (and beyond)
with master. These changes are:

  * 'LocalRequest' implements 'Clone'.
  * 'LocalResponse' doesn't implement 'DerefMut<Target=Response>'.
    Instead, direct methods on the type, such as 'into_string()', can
    be used to read the 'Response'.
  * 'Response::body()' returns an '&ResponseBody' as opposed to '&mut
    ResponseBody', which is returned by a new 'Response::body_mut()'.
  * '&ResponseBody' implements 'known_size()` to retrieve a body's size,
    if it is known.

Sergio Benitez d89c7024ed Replace 'Manifest' with 'Cargo'.
This is largely an internal change. Prior to this commit, the 'Manifest'
type, now replaced with the 'Cargo' type, robbed responsibility from the
core 'Rocket' type. This new construction restores the previous
responsibility and makes it clear that 'Cargo' is _only_ for freezing,
and representing the stability of, Rocket's internal state.

Sergio Benitez 1704ff7743 Asyncify 'Handler'. Rename 'ErrorHandlerFuture' to 'CatcherFuture'. 2020-07-11 09:24:30 -07:00
Sergio Benitez f7cd455558 Make 'NamedFile' async. Fix 'Handler' trait.
Previously, 'NamedFile::open()' called a synchronous I/O method. This
commit changes it to instead use tokio's 'File' for async I/O.

To allow this to change, the 'Handler' trait was fixed to enforce that
the lifetime of '&self', the reference to the handler, outlives the
incoming request. As a result, futures returned from a handler can hold
a reference to 'self'.
2020-07-11 09:24:30 -07:00
Sergio Benitez 2465e2f136 Make 'Responder' trait sync; fix its lifetimes.
In summary, this commit modifies 'Responder' so that:

  * ..it is no longer 'async'. To accommodate, the 'sized_body' methods
    in 'Response' and 'ResponseBuilder' are no longer 'async' and accept
    an optional size directly. If none is supplied, Rocket will attempt
    to compute the size, by seeking, before writing out the response.
    The 'Body' type was also changed to differentiate between its sized
    'Seek' and chunked body variants.

  * ..'&Request' gains a lifetime: 'r, and the returned 'Response' is
    parameterized by a new 'o: 'r. This allows responders to return
    references from the request or those that live longer.

Sergio Benitez 12308b403f Add '#[rocket::launch]' attribute.
The attribute is applied everywhere it can be across the codebase and is
the newly preferred method for launching an application. This commit
also makes '#[rocket::main]` stricter by warning when it is applied to
functions other than 'main'.
2020-07-11 09:24:29 -07:00
Jeb Rosen bc1b90cbdb Add '#[rocket::main]' attribute and make 'launch()' an 'async fn'.
'#[rocket::main]' works like '#[rocket::async_test]', but it uses
tokio's multithreaded scheduler.

Jeb Rosen b0238e5110 Make 'Fairing::on_attach()' async.
This transitively requires that 'Rocket::inspect()', 'Client::new()',
and 'Client::untracked()' also become async.
2020-07-11 09:24:29 -07:00
Jeb Rosen dea940c7a8 Defer execution of operations on 'Rocket' until their effects will be
observed.

This is a prerequisite for async on_attach fairings. 'Rocket' is now a
builder wrapper around the 'Manifest' type, with operations being
applied when needed by 'launch()', 'Client::new()', or 'inspect()'.
'inspect()' returns an '&Manifest', which now provides the methods that
could be called on an '&Rocket'.
2020-07-11 09:24:29 -07:00
Sergio Benitez c0c6c79a7f Use 'async_trait' for 'Responder'.

  * Re-export 'tokio' and 'futures' from the crate root.
  * Make 'ResponseBuilder::sized_body()' and 'async fn'.
  * Remove the 'Future' implementation for 'ResponseBuilder'.
  * Add 'ResponseBuilder::finalize()' for finalizing the builder.
2020-07-11 09:24:29 -07:00

2020-07-11 09:24:29 -07:00
Michael Howell c9d0af09d6 Use 'AsyncSeek' for sized bodies in 'Response's.
In order to avoid making 'ResponseBuilder::sized_body' an asynchronous
function, the seeking is deferred until finalization. 'finalize()' is
replaced with '.await', and 'ResponseBuilder::ok()' is an 'async fn'.
