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.

Jeb Rosen 92af8fca72 Update to 'tokio' 1.0, 'hyper' 0.14. 2021-01-13 15:22:16 -08:00
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 549c9241c4 Require data limits on 'Data::open()'.
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 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 1704ff7743 Asyncify 'Handler'. Rename 'ErrorHandlerFuture' to 'CatcherFuture'. 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.

Jeb Rosen 560f0977d3 Revamp testing system for async.
* body_string_wait and body_bytes_wait are removed; use `.await` instead
* `dispatch()` is now an async fn and must be .await-ed
* Add `#[rocket::async_test]` macro, similar in purpose to `tokio::test`
* Tests now use either `rocket::async_test(async { })` or
  `#[rocket::async_test]` in order to `.await` the futures returned
  from `dispatch()` and `body_{string,bytes}()`
* Update 'test.sh' to reflect the tests that should be passing.

Broken:

* Cloned dispatch and mut_dispatch() with a live previous response now both fail, due to a (partial) check for mutable aliasing in LocalRequest.
* Some tests are still failing and need example-specific changes.

Sergio Benitez 61f107f550 Reimplement route attribute as a proc-macro.
This commits also implement the query reform from #608. It also consists
of many, many breaking changes. Among them are:

  * Query parts in route paths use new query reform syntax.
  * Routing for queries is now lenient.
    - Default ranking has changed to reflect query reform.
  * Format routing matching has been fixed.
    - Routes with formats matching "accept" will always collide.
    - Routes with formats matching "content-type" require requests to
      have an equivalent content-type header to match.
    - Requests with imprecise content-types are treated as not having a
      content-type.
  * Generated routes and catchers respect visibility modifiers.
  * Raw getter methods from request were renamed and retooled.
    - In particular, the index parameter is based on segments in the
      route path, not dynamic parameters.
  * The method-based attributes no longer accept a keyed 'path'.
  * The 'rocket_codegen' crate is gone and will no longer be public.
  * The 'FormItems' iterator emits values of type 'FormItem'.
    - The internal form items' string can no longer be retrieved.
  * In general, routes are more strictly validated.
  * Logging from codegen now funnels through logging infrastructure.
  * Routing has been optimized by caching routing metadata.

Sergio Benitez 56c6a96f6a Overhaul URI types.
This is fairly large commit with several entangled logical changes.

The primary change in this commit is to completely overhaul how URI
handling in Rocket works. Prior to this commit, the `Uri` type acted as
an origin API. Its parser was minimal and lenient, allowing URIs that
were invalid according to RFC 7230. By contrast, the new `Uri` type
brings with it a strict RFC 7230 compliant parser. The `Uri` type now
represents any kind of valid URI, not simply `Origin` types. Three new
URI types were introduced:

  * `Origin` - represents valid origin URIs
  * `Absolute` - represents valid absolute URIs
  * `Authority` - represents valid authority URIs

The `Origin` type replaces `Uri` in many cases:

  * As fields and method inputs of `Route`
  * The `&Uri` request guard is now `&Origin`
  * The `uri!` macro produces an `Origin` instead of a `Uri`

The strict nature of URI parsing cascaded into the following changes:

  * Several `Route` methods now `panic!` on invalid URIs
  * The `Rocket::mount()` method is (correctly) stricter with URIs
  * The `Redirect` constructors take a `TryInto<Uri>` type
  * Dispatching of a `LocalRequest` correctly validates URIs

Overall, URIs are now properly and uniformly handled throughout Rocket's
codebase, resulting in a more reliable and correct system.

In addition to these URI changes, the following changes are also part of
this commit:

  * The `LocalRequest::cloned_dispatch()` method was removed in favor of
    chaining `.clone().dispatch()`.
  * The entire Rocket codebase uses `crate` instead of `pub(crate)` as a
    visibility modifier.
  * Rocket uses the `crate_visibility_modifier` and `try_from` features.

A note on unsafety: this commit introduces many uses of `unsafe` in the
URI parser. All of these uses are a result of unsafely transforming byte
slices (`&[u8]` or similar) into strings (`&str`). The parser ensures
that these casts are safe, but of course, we must label their use
`unsafe`. The parser was written to be as generic and efficient as
possible and thus can parse directly from byte sources. Rocket, however,
does not make use of this fact and so would be able to remove all uses
of `unsafe` by parsing from an existing `&str`. This should be
considered in the future.

Fixes #443.
Resolves #263.

Sergio Benitez f171dc9d09 Reorganize repository.
The directory structure has changed to better isolate crates serving
core and contrib. The new directory structure is:

  contrib/
    lib/ - the contrib library
  core/
    lib/ - the core Rocket library
    codegen/ - the "compile extension" codegen library
    codegen_next/ - the new proc-macro library
  examples/ - unchanged
  scripts/ - unchanged
  site/ - unchanged

This commit also removes the following files:

  appveyor.yml - AppVeyor (Rust on Windows) is far too spotty for use
  rustfmt.toml - rustfmt is, unfortunately, not mature enough for use

Finally, all example Cargo crates were marked with 'publish = false'.

Sergio Benitez b8ba7b855f Remove Session in favor of private cookies. New testing API.
Sessions
--------

This commit removes the `Session` type in favor of methods on the
`Cookies` types that allow for adding, removing, and getting private
(signed and encrypted) cookies. These methods provide a superset of
the functionality of `Session` while also being a minimal addition to
the existing API. They can be used to implement the previous `Session`
type as well as other forms of session storage. The new methods are:

  * Cookie::add_private(&mut self, Cookie)
  * Cookie::remove_private(&mut self, Cookie)
  * Cookie::get_private(&self, &str)

Resolves #20

Testing
-------

This commit removes the `rocket::testing` module. It adds the
`rocket::local` module which provides a `Client` type for local
dispatching of requests against a `Rocket` instance. This `local`
package subsumes the previous `testing` package.

Rocket Examples
---------------

The `forms`, `optional_result`, and `hello_alt_methods` examples have
been removed. The following example have been renamed:

  * extended_validation -> form_validation
  * hello_ranks -> ranking
  * from_request -> request_guard
  * hello_tls -> tls

Other Changes
-------------

This commit also includes the following smaller changes:

  * Config::{development, staging, production} constructors have been
    added for easier creation of default `Config` structures.
  * The `Config` type is exported from the root.
  * `Request` implements `Clone` and `Debug`.
  * `Request::new` is no longer exported.
  * A `Response::body_bytes` method was added to easily retrieve a
    response's body as a `Vec<u8>`.
2017-06-08 17:34:50 -07:00
Sergio Benitez 9b955747e4 Remove config global state. Use Responder::respond_to.
This commit includes two major changes to core:

  1. Configuration state is no longer global. The `config::active()`
     function has been removed. The active configuration can be
     retrieved via the `config` method on a `Rocket` instance.

  2. The `Responder` trait has changed. `Responder::respond(self)` has
     been removed in favor of `Responder::respond_to(self, &Request)`.
     This allows responders to dynamically adjust their response based
     on the incoming request.

Additionally, it includes the following changes to core and codegen:

  * The `Request::guard` method was added to allow for simple
    retrivial of request guards.
  * The `Request::limits` method was added to retrieve configured
    limits.
  * The `File` `Responder` implementation now uses a fixed size body
    instead of a chunked body.
  * The `Outcome::of<R: Responder>(R)` method was removed while
    `Outcome::from<R: Responder(&Request, R)` was added.
  * The unmounted and unmanaged limits are more cautious: they will only
    emit warnings when the `Rocket` receiver is known.

This commit includes one major change to contrib:

  1. To use contrib's templating, the fairing returned by
     `Template::fairing()` must be attached to the running Rocket
     instance.

Additionally, the `Display` implementation of `Template` was removed. To
directly render a template to a `String`, the new `Template::show`
method can be used.

Sergio Benitez 1e5a1b8940 Remove 'testing' feature. Close stream on network error.
This is a breaking change.

The `testing` feature no longer exists. Testing structures can now be
accessed without any features enabled.

Prior to this change, Rocket would panic when draining from a network
stream failed. With this change, Rocket force closes the stream on any
error.

This change also ensures that the `Fairings` launch output only prints
if at least one fairing has been attached.

Sergio Benitez cc22836867 Precisely route formats. Make 'content_type' an 'Option' in 'Request'.
This commit changes the routing algorithm. In particular, it enforces
precise matching of formats. With this change, a route with a specified
format only matches requests that have the same format specified. A
route with no format specified matches any request's format. This is
contrast to the previous behavior, where a route without a specified
format would match requests regardless of their format or whether one
was specified.

This commit also changes the following:
  * The return type of the 'content_type' method of 'Request' is now
    'Option<ContentType>'.
  * The 'ContentType' request guard forwards when the request has no
    specified ContentType.
  * The 'add_header' and 'replace_header' methods take the header
    argument generically.

Closes #120.

Sergio Benitez 44f5f1998d New HTTP types: ContentType, Status. Responder/Handler/ErrorHandler changed.
This is a complete rework of `Responder`s and of the http backend in
general. This gets Rocket one step closer to HTTP library independence,
enabling many future features such as transparent async I/O, automatic
HEAD request parsing, pre/post hooks, and more.

Summary of changes:

  * `Responder::response` no longer takes in `FreshHyperResponse`.
    Instead, it returns a new `Response` type.
  * The new `Response` type now encapsulates a full HTTP response. As a
    result, `Responder`s now return it.
  * The `Handler` type now returns an `Outcome` directly.
  * The `ErrorHandler` returns a `Result`. It can no longer forward,
    which made no sense previously.
  * `Stream` accepts a chunked size parameter.
  * `StatusCode` removed in favor of new `Status` type.
  * `ContentType` significantly modified.
