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`.
While offering some utility, the lifetime did not carry its weight, and
in practice offered no further ability to borrow. This greatly
simplifies request guard implementations.
This allows us to test all of the "core" crates (and the guide) by
testing the root workspace, and all of the examples by testing in the
examples workspace.
This changes core routing so that '<path..>' in a route URI matches zero
or more segments. Previously, '<path..>' matched _1_ or more.
* Routes '$a' and '$b/<p..>' collide if $a and $b previously collided.
* For example, '/' now collides with '/<p..>'.
* Request '$a' matches route '$b/<p..>' if $a previously matched $b.
* For example, request '/' matches route '/<p..>'.
Resolves#985.
So. Many. Changes.
This is an insane commit: simultaneously one of the best (because of all
the wonderful improvements!) and one of the worst (because it is just
massive) in the project's history.
Routing:
* All UTF-8 characters are accepted everywhere in route paths. (#998)
* `path` is now `uri` in `route` attribute: `#[route(GET, path = "..")]`
becomes `#[route(GET, uri = "..")]`.
Forms Revamp
* All form related types now reside in a new `form` module.
* Multipart forms are supported. (resolves#106)
* Collections are supported in forms and queries. (resolves#205)
* Nested structures in forms and queries are supported. (resolves#313)
* Form fields can be ad-hoc validated with `#[field(validate = expr)]`.
* `FromFormValue` is now `FromFormField`, blanket implements `FromForm`.
* Form field values are always percent-decoded apriori.
Temporary Files
* A new `TempFile` data and form guard allows streaming data directly to a
file which can then be persisted.
* A new `temp_dir` config parameter specifies where to store `TempFile`.
* The limits `file` and `file/$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.
This commit also improves config pretty-printing and warning messages.
It also fixes an issue that resulted in config value deprecation
warnings not being emitted. The 'workers' value is now a 'usize', not a
'u16'; contrib pool sizes now default to 'workers * 2'.
Closes#1470.
This commit reverts most of dea940c7 and d89c7024. The "fix" is to run
attach fairings on a new thread. If a runtime is already running, it is
used. Otherwise, the future is executed in a single-threaded executor.
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.
Resolves#852.
Resolves#209.
Closes#1404.
Closes#652.
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.
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.
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.
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'.
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.
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.

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.
