Sergio Benitez 7e913eb8ac Report as many form errors as possible. 2022-11-12 04:11:18 -08:00
Sergio Benitez 8166ad0c7c Fix error field names in 'FromForm' derive.
Prior to this commit, the `FromForm` derive could pair the incorrect
field name with a failing validation. The bug was caused by using two
mismatched iterators in a `quote!()` invocation. Specifically, the first
iterator emitted validation calls for all fields that had validation
applied, while the second emitted field names for all fields,
irrespective of whether the field had any validation applied. The two
iterators were effectively zipped to create the final error, creating
the bug.

This commit fixes the issue by correctly matching field names with their
validators at the expense of an additional allocation, necessitated by
the `quote` crate's inability to access subfields in a repetition.

Fixes #2394.

Sergio Benitez 6bdd2f8186 Consider form parsing strategy for 'Vec', 'Map'.
Prior to this commit, 'Vec', 'HashMap', and 'BTreeMap' would parse
leniently irrespetive of the requested parsing strategy. This commit
changes their behavior so that the parsing strategy is respected.

Resolves #2131.

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 e7934a2a3f Parse inner form 'T' in 'Option<T>' strictly.
This behavior more closely matches the expectation that a missing field
results in 'None'.

Also cleans up forms docs for readability, completeness.

Sergio Benitez 4e06ee64aa Test 'secret_key' validation, now on pre-launch.
Prior to this commit, it was not possible to test Rocket crates in
production mode without setting a global secret key or bypassing secret
key checking - the testing script did the latter. The consequence is
that it became impossible to test secret key related failures because
the tests passed regardless.

This commit undoes this. As a consequence, all tests are now aware of
the difference between debug and release configurations, the latter of
which validates 'secret_key' by default. New 'Client::debug()' and
'Client::debug_with()' simplify creating an instance of 'Client' with
configuration in debug mode to avoid undesired test failures.

The summary of changes in this commit are:

  * Config 'secret_key' success and failure are now tested.
  * 'secret_key' validation was moved to pre-launch from 'Config:from()'.
  * 'Config::from()' only extracts the config.
  * Added 'Config::try_from()' for non-panicking extraction.
  * 'Config' now knows the profile it was extracted from.
  * The 'Config' provider sets a profile of 'Config.profile'.
  * 'Rocket', 'Client', 'Fairings', implement 'Debug'.
  * 'fairing::Info' implements 'Copy', 'Clone'.
  * 'Fairings' keeps track of, logs attach fairings.
  * 'Rocket::reconfigure()' was added to allow modifying a config.

Internally, the testing script was refactored to properly test the
codebase with the new changes. In particular, it no longer sets a rustc
'cfg' to avoid secret-key checking.

Resolves #1543.
Fixes #1564.

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.
