This changes core routing so that panics in all handlers are handled by
emitting a long message explaining that panics are bad and invoking the
500 error catcher. If the 500 error catcher fails, Rocket's default 500
catcher is used.
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.
The iterator may be empty. This changes the return type of
'Request::segments()' from 'Option<Segments>' to simply 'Segments'.
Internally also adds a 'Client::debug()' for easier request testing.
* Add a `msg!()` macro to easily change a field validation message.
* Allow a field to refer to itself via `self.field`.
* Improve the various field validation traits.
This commit completely revamps the way that codegen handles route URI
"parameters". The changes are largely internal. In summary, codegen code
is better organized, better written, and less subject to error.
There are three breaking changes:
* `path` is now `uri` in `route` attribute: `#[route(GET, path = "..")]`
becomes `#[route(GET, uri = "..")]`.
* the order of execution for path and query guards relative to
each-other is now unspecified
* URI normalization now normalizes the query part as well.
Several error messages were improved. A couple of bugs were fixed:
* Prior to this commit, Rocket would optimistically try to parse every
segment of a URI as an ident, in case one was needed in the future.
A bug in rustc results in codegen "panicking" if the segment
couldn't _lex_ as an ident. This panic didn't manifest until far
after expansion, unfortunately. This wasn't a problem before as we
only allowed ident-like segments (ASCII), but now that we allow any
UTF-8, the bug surfaced. This was fixed by never attempting to parse
non-idents as idents.
* Prior to this commit, it was impossible to generate typed URIs for
paths that ignored path parameters via the recently added syntax
`<_>`: the macro would panic. This was fixed by, well, handling
these ignored parameters.
Some minor additions:
* Added `RawStr::find()`, expanding its `Pattern`-based API.
* Added an internal mechanism to dynamically determine if a `UriPart`
is `Path` or `Query`.
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.
Prior to this commit, it was impossible to 'use' a route from a separate
namespace for use in a 'routes!' macro. Naturally, this was a common
source of confusion amongst users. This commit obviates this deficiency
by generating a "proxy" structure that can be imported and converted
into a 'Route'/'Catcher' or their static variants.
This change is largely backwards compatible but can break existing code
when routes are named identically to other types in the namespace.
