This commit changes the `FromForm` derive codegen so that it
consistently emits tokens with call site hygiene. This allows `FromForm`
derives to be emitted my macros more reliably.
Previously, the `NotFound` status code was used to signal many kinds of
recoverable, forwarding errors. This included validation errors, incorrect
Content-Type errors, and more.
This commit modifies the status code used to forward in these instances to more
precisely indicate the forwarding condition. In particular:
* Parameter `FromParam` errors now forward as 422 (`UnprocessableEntity`).
* Query paramater errors now forward as 422 (`UnprocessableEntity`).
* Use of incorrect form content-type forwards as 413 (`UnsupportedMediaType`).
* `WebSocket` guard now forwards as 400 (`BadRequest`).
* `&Host`, `&Accept`, `&ContentType`, `IpAddr`, and `SocketAddr` all forward
with a 500 (`InternalServerError`).
Additionally, the `IntoOutcome` trait was overhauled to support functionality
previously offered by methods on `Outcome`. The `Outcome::forward()` method now
requires a status code to use for the forwarding outcome.
Finally, logging of `Outcome`s now includes the relevant status code.
Resolves#2626.
The primary motivation is to deconflate the leading `F`s in `Failure` and
`Forward`. In particular, when using a generics, we used `F` for forward, which
could easily be confused for `F` for `Failure`. This resolves the conflation.
The warning is fairly conservative. Heuristics are used to determine if a call
to `tokio::spawn()` occurs in the `#[launch]` function.
Addresses #2547.
The codegen for field validations previously included a closure that
could potentially partially borrow a 'Copy' field of the context
structure. To prevent this, 'let'-assign the field before the closure is
created, and use the assignment inside of the closure.
Prior to this commit, all forward outcomes resulted in a 404. This
commit changes request and data guards so that they are able to provide
a `Status` on `Forward` outcomes. The router uses this status, if the
final outcome is to forward, to identify the catcher to invoke.
The net effect is that guards can now customize the status code of a
forward and thus the error catcher invoked if the final outcome of a
request is to forward.
Resolves#1560.
Previously, if a module used or defined a type alias for Result,
FromFormField derives would fail to compile as it would use the type
alias instead of the fully qualified type.
This commit makes passing compile UI tests optional, allowing the CI to
succeed even when UI tests fail. This change was made because UI tests
are highly susceptible to false negatives due to benign rustc compiler
output changes. A failure resulting from such a benign change inhibits
progress in the main branch due to failing PR testing which would have
otherwise passed.
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.
