Revamp configuration. 

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.

# Configuration
Rocket aims to have a flexible and usable configuration system. Rocket
applications can be configured via a configuration file, through environment
variables, or both. Configurations are separated into three environments:
development, staging, and production. The working environment is selected via an
environment variable.
Rocket's configuration system is flexible. Based on [Figment](@figment), it
allows you to configure your application the way _you_ want while also providing
with a sensible set of defaults.
## Environment
## Overview
At any point in time, a Rocket application is operating in a given
_configuration environment_. There are three such environments:
Rocket's configuration system is based on Figment's [`Provider`]s, types which
provide configuration data. Rocket's [`Config`] and [`Config::figment()`], as
well as Figment's [`Toml`] and [`Json`], are some examples of providers.
Providers can be combined into a single [`Figment`] provider from which any
configuration structure that implements [`Deserialize`] can be extracted.
* `development` (short: `dev`)
* `staging` (short: `stage`)
* `production` (short: `prod`)
Rocket expects to be able to extract a [`Config`] structure from the provider it
is configured with. This means that no matter which configuration provider
Rocket is asked to use, it must be able to read the following configuration
values:
Without any action, Rocket applications run in the `development` environment for
debug builds and the `production` environment for non-debug builds. The
environment can be changed via the `ROCKET_ENV` environment variable. For
example, to launch an application in the `staging` environment, we can run:
| key | kind | description | debug/release default |
|----------------|-----------------|-------------------------------------------------|-----------------------|
| `address` | `IpAddr` | IP address to serve on | `127.0.0.1` |
| `port` | `u16` | Port to serve on. | `8000` |
| `workers` | `u16` | Number of threads to use for executing futures. | cpu core count * 2 |
| `keep_alive` | `u32` | Keep-alive timeout seconds; disabled when `0`. | `5` |
| `log_level` | `LogLevel` | Max level to log. (off/normal/debug/critical) | `normal`/`critical` |
| `cli_colors` | `bool` | Whether to use colors and emoji when logging. | `true` |
| `secret_key` | `SecretKey` | Secret key for signing and encrypting values. | `None` |
| `tls` | `TlsConfig` | TLS configuration, if any. | `None` |
| `tls.key` | `&[u8]`/`&Path` | Path/bytes to DER-encoded ASN.1 PKCS#1/#8 key. | |
| `tls.certs` | `&[u8]`/`&Path` | Path/bytes to DER-encoded X.509 TLS cert chain. | |
| `limits` | `Limits` | Streaming read size limits. | [`Limits::default()`] |
| `limits.$name` | `&str`/`uint` | Read limit for `$name`. | forms = "32KiB" |
| `ctrlc` | `bool` | Whether `ctrl-c` initiates a server shutdown. | `true` |
```sh
ROCKET_ENV=stage cargo run
```
### Profiles
Note that you can use the short or long form of the environment name to specify
the environment, `stage` _or_ `staging` here. Rocket tells us the environment we
have chosen and its configuration when it launches:
Configurations can be arbitrarily namespaced by [`Profile`]s. Rocket's
[`Config`] and [`Config::figment()`] providers automatically set the
configuration profile to "debug" when compiled in "debug" mode and "release"
when compiled in release mode. With the exception of `log_level`, which changes
from `normal` in debug to `critical` in release, all of the default
configuration values are the same in all profiles. What's more, all
configuration values _have_ defaults, so no configuration needs to be supplied
to get an application going.
```sh
$ sudo ROCKET_ENV=staging cargo run
In addition to any profiles you declare, there are two meta-profiles, `default`
and `global`, which can be used to provide values that apply to _all_ profiles.
Values provided in a `default` profile are used as fall-back values when the
selected profile doesn't contain a requested values, while values in the
`global` profile supplant any values with the same name in any profile.

## Rocket.toml
### Secret Key
An optional `Rocket.toml` file can be used to specify the configuration
parameters for each environment. If it is not present, the default configuration
parameters are used. Rocket searches for the file starting at the current
working directory. If it is not found there, Rocket checks the parent directory.
Rocket continues checking parent directories until the root is reached.
The `secret_key` parameter configures a cryptographic key to use when encrypting
application values. In particular, the key is used to encrypt [private cookies],
which are available only when the `secrets` crate feature is enabled.
The file must be a series of TOML tables, at most one for each environment, and
an optional "global" table. Each table contains key-value pairs corresponding to
configuration parameters for that environment. If a configuration parameter is
missing, the default value is used. The following is a complete `Rocket.toml`
file, where every standard configuration parameter is specified with the default
value:
When compiled in debug mode, a fresh key is generated automatically. In release
mode, Rocket requires you to set a secret key if the `secrets` feature is
enabled. Failure to do so results in a hard error at launch time. The value of
the parameter may either be a 256-bit base64 or hex string or a slice of 32
bytes.
```toml
[development]
address = "localhost"
port = 8000
workers = [number of cpus * 2]
keep_alive = 5
log = "normal"
secret_key = [randomly generated at launch]
limits = { forms = 32768 }
[private cookies]: ../requests/#private-cookies
[staging]
address = "0.0.0.0"
port = 8000
workers = [number of cpus * 2]
keep_alive = 5
log = "normal"
secret_key = [randomly generated at launch]
limits = { forms = 32768 }
[production]
address = "0.0.0.0"
port = 8000
workers = [number of cpus * 2]
keep_alive = 5
log = "critical"
secret_key = [randomly generated at launch]
limits = { forms = 32768 }
```
The `workers` and `secret_key` default parameters are computed by Rocket
automatically; the values above are not valid TOML syntax. When manually
specifying the number of workers, the value should be an integer: `workers =
10`. When manually specifying the secret key, the value should a random 256-bit
value, encoded as a base64 or base16 string. Such a string can be generated
using a tool like openssl: `openssl rand -base64 32`.
The "global" pseudo-environment can be used to set and/or override configuration
parameters globally. A parameter defined in a `[global]` table sets, or
overrides if already present, that parameter in every environment. For example,
given the following `Rocket.toml` file, the value of `address` will be
`"1.2.3.4"` in every environment:
```toml
[global]
address = "1.2.3.4"
[development]
address = "localhost"
[production]
address = "0.0.0.0"
```
## Data Limits
### Limits
The `limits` parameter configures the maximum amount of data Rocket will accept
for a given data type. The parameter is a table where each key corresponds to a
data type and each value corresponds to the maximum size in bytes Rocket
should accept for that type.
for a given data type. The value is expected to be a dictionary table where each
key corresponds to a data type and each value corresponds to the maximum size in
bytes Rocket should accept for that type. Rocket can parse both integers
(`32768`) or SI unit based strings (`"32KiB"`) as limits.
By default, Rocket limits forms to 32KiB (32768 bytes). To increase the limit,
simply set the `limits.forms` configuration parameter. For example, to increase
the forms limit to 128KiB globally, we might write:
By default, Rocket specifies a `32 KiB` limit for incoming forms. Since Rocket
requires specifying a read limit whenever data is read, external data guards may
also choose to have a configure limit via the `limits` parameter. The
[`rocket_contrib::Json`] type, for instance, uses the `limits.json` parameter.
[`rocket_contrib::Json`]: @api/rocket_contrib/json/struct.Json.html
### TLS
Rocket includes built-in, native support for TLS >= 1.2 (Transport Layer
Security). In order for TLS support to be enabled, Rocket must be compiled with
the `"tls"` feature:
```toml
[global.limits]
forms = 131072
[dependencies]
rocket = { version = "0.5.0-dev", features = ["tls"] }
```
The `limits` parameter can contain keys and values that are not endemic to
Rocket. For instance, the [`Json`] type reads the `json` limit value to cap
incoming JSON data. You should use the `limits` parameter for your application's
data limits as well. Data limits can be retrieved at runtime via the
[`Request::limits()`] method.
TLS is configured through the `tls` configuration parameter. The value of `tls`
is a dictionary with two keys: `certs` and `key`, described in the table above.
Each key's value may be either a path to a file or raw bytes corresponding to
the expected value. When a path is configured in a file source, such as
`Rocket.toml`, relative paths are interpreted as being relative to the source
file's directory.
[`Request::limits()`]: @api/rocket/struct.Request.html#method.limits
[`Json`]: @api/rocket_contrib/json/struct.Json.html#incoming-data-limits
! warning: Rocket's built-in TLS implements only TLS 1.2 and 1.3. As such, it
may not be suitable for production use.
## Extras
## Default Provider
In addition to overriding default configuration parameters, a configuration file
can also define values for any number of _extra_ configuration parameters. While
these parameters aren't used by Rocket directly, other libraries, or your own
application, can use them as they wish. As an example, the
[Template](@api/rocket_contrib/templates/struct.Template.html) type
accepts a value for the `template_dir` configuration parameter. The parameter
can be set in `Rocket.toml` as follows:
Rocket's default configuration provider is [`Config::figment()`]; this is the
provider that's used when calling [`rocket::ignite()`].
The default figment merges, at a per-key level, and reads from the following
sources, in ascending priority order:
1. [`Config::default()`] - which provides default values for all parameters.
2. `Rocket.toml` _or_ TOML file path in `ROCKET_CONFIG` environment variable.
3. `ROCKET_` prefixed environment variables.
The selected profile is the value of the `ROCKET_PROFILE` environment variable,
or if it is not set, "debug" when compiled in debug mode and "release" when
compiled in release mode.
As a result, without any effort, Rocket's server can be configured via a
`Rocket.toml` file and/or via environment variables, the latter of which take
precedence over the former. Note that neither the file nor any environment
variables need to be present as [`Config::default()`] is a complete
configuration source.
[`Config::default()`]: @api/rocket/struct.Config.html#method.default
### Rocket.toml
Rocket searches for `Rocket.toml` or the filename in a `ROCKET_CONFIG`
environment variable starting at the current working directory. If it is not
found, the parent directory, its parent, and so on, are searched until the file
is found or the root is reached. If the path set in `ROCKET_CONFIG` is absolute,
no such search occurs, and the set path is used directly.
The file is assumed to be _nested_, so each top-level key declares a profile and
its values the value for the profile. The following is an example of what such a
file might look like:
```toml
[development]
template_dir = "dev_templates/"
## defaults for _all_ profiles
[default]
address = "0.0.0.0"
limits = { forms = "64 kB", json = "1 MiB" }
[production]
template_dir = "prod_templates/"
## set only when compiled in debug mode, i.e, `cargo build`
[debug]
port = 8000
## only the `json` key from `default` will be overridden; `forms` will remain
limits = { json = "10MiB" }
## set only when the `nyc` profile is selected
[nyc]
port = 9001
## set only when compiled in release mode, i.e, `cargo build --release`
## don't use this secret_key! generate your own and keep it private!
[release]
port = 9999
secret_key = "hPRYyVRiMyxpw5sBB1XeCMN1kFsDCqKvBi2QJxBVHQk="
```
This sets the `template_dir` extra configuration parameter to `"dev_templates/"`
when operating in the `development` environment and `"prod_templates/"` when
operating in the `production` environment. Rocket will prepend the `[extra]` tag
to extra configuration parameters when launching:
### Environment Variables
```sh
🔧 Configured for development.
=> ...
=> [extra] template_dir: "dev_templates/"
```
To retrieve a custom, extra configuration parameter in your application, we
recommend using an [ad-hoc attach fairing] in combination with [managed state].
For example, if your application makes use of a custom `assets_dir` parameter:
[ad-hoc attach fairing]: ../fairings/#ad-hoc-fairings
[managed state]: ../state/#managed-state
```toml
[development]
assets_dir = "dev_assets/"
[production]
assets_dir = "prod_assets/"
```
The following code will:
1. Read the configuration parameter in an ad-hoc `attach` fairing.
2. Store the parsed parameter in an `AssetsDir` structure in managed state.
3. Retrieve the parameter in an `assets` route via the `State` guard.
```rust
# #[macro_use] extern crate rocket;
use std::path::{Path, PathBuf};
use rocket::State;
use rocket::response::NamedFile;
use rocket::fairing::AdHoc;
struct AssetsDir(String);
#[get("/<asset..>")]
async fn assets(asset: PathBuf, assets_dir: State<'_, AssetsDir>) -> Option<NamedFile> {
NamedFile::open(Path::new(&assets_dir.0).join(asset)).await.ok()
}
#[launch]
fn rocket() -> rocket::Rocket {
rocket::ignite()
.mount("/", routes![assets])
.attach(AdHoc::on_attach("Assets Config", |mut rocket| async {
let assets_dir = rocket.config().await
.get_str("assets_dir")
.unwrap_or("assets/")
.to_string();
Ok(rocket.manage(AssetsDir(assets_dir)))
}))
}
```
## Environment Variables
All configuration parameters, including extras, can be overridden through
environment variables. To override the configuration parameter `{param}`, use an
environment variable named `ROCKET_{PARAM}`. For instance, to override the
"port" configuration parameter, you can run your application with:
```sh
ROCKET_PORT=3721 ./your_application
🔧 Configured for development.
=> ...
=> port: 3721
```
Environment variables take precedence over all other configuration methods: if
the variable is set, it will be used as the value for the parameter. Variable
values are parsed as if they were TOML syntax. As illustration, consider the
Rocket reads all environment variable names prefixed with `ROCKET_` using the
string after the `_` as the name of a configuration value as the value of the
parameter as the value itself. Environment variables take precedence over values
in `Rocket.toml`. Values are parsed as loose form of TOML syntax. Consider the
following examples:
```sh
@ -249,80 +187,161 @@ ROCKET_ARRAY=[1,"b",3.14]
ROCKET_DICT={key="abc",val=123}
```
## Programmatic
## Extracting Values
In addition to using environment variables or a config file, Rocket can also be
configured using the [`rocket::custom()`] method and [`ConfigBuilder`]:
Your application can extract any configuration that implements [`Deserialize`]
from the configured provider, which is exposed via [`Rocket::figment()`] and
[`Cargo::figment()`]:
```rust

Both values recognized by Rocket and values _not_ recognized by Rocket can be
extracted. This means you can configure values recognized by your application in
Rocket's configuration sources directly. The next section describes how you can
customize configuration sources by supplying your own `Provider`.
Because it is common to store configuration in managed state, Rocket provides an
`AdHoc` fairing that 1) extracts a configuration from the configured provider,
2) pretty prints any errors, and 3) stores the value in managed state:
```rust
# #[macro_use] extern crate rocket;
# extern crate serde;
# use serde::Deserialize;
# #[derive(Deserialize)]
# struct Config {
# port: u16,
# custom: Vec<String>,
# }
use rocket::{State, fairing::AdHoc};
#[get("/custom")]
fn custom(config: State<'_, Config>) -> String {
config.custom.get(0).cloned().unwrap_or("default".into())
}
#[launch]
fn rocket() -> _ {
rocket::ignite()
.mount("/", routes![custom])
.attach(AdHoc::config::<Config>())
}
```

## Custom Providers
A custom provider can be set via [`rocket::custom()`], which replaces calls to
[`rocket::ignite()`]. The configured provider can be built on top of
[`Config::figment()`], [`Config::default()`], both, or neither. The
[Figment](@figment) documentation has full details on instantiating existing
providers like [`Toml`] and [`Json`] as well as creating custom providers for
more complex cases.
! note: You may need to depend on `figment` and `serde` directly.
Rocket reexports `figment` from its crate root, so you can refer to `figment`
types via `rocket::figment`. However, Rocket does not enable all features from
the figment crate. As such, you may need to import `figment` directly:
`
figment = { version = "0.9", features = ["env", "toml", "json"] }
`
Furthermore, you should directly depend on `serde` when using its `derive`
feature, which is also not enabled by Rocket:
`
serde = { version = "1", features = ["derive"] }
`
As a first example, we override configuration values at runtime by merging
figment's tuple providers with Rocket's default provider:
```rust
# #[macro_use] extern crate rocket;
use rocket::config::{Config, Environment};
use rocket::data::{Limits, ToByteUnit};
# fn build_config() -> rocket::config::Result<Config> {
let config = Config::build(Environment::Staging)
.address("1.2.3.4")
.port(9234)
.finalize()?;
# Ok(config)
# }
#[launch]
fn rocket() -> _ {
let figment = rocket::Config::figment()
.merge(("port", 1111))
.merge(("limits", Limits::new().limit("json", 2.mebibytes())));
# let config = build_config().expect("config okay");
# /*
rocket::custom(config)
.mount("/", routes![/* .. */])
.launch()
.await;
# */
rocket::custom(figment).mount("/", routes![/* .. */])
}
```
Configuration via `rocket::custom()` replaces calls to `rocket::ignite()` and
all configuration from `Rocket.toml` or environment variables. In other words,
using `rocket::custom()` results in `Rocket.toml` and environment variables
being ignored.
More involved, consider an application that wants to use Rocket's defaults for
[`Config`], but not its configuration sources, while allowing the application to
be configured via an `App.toml` file and `APP_` environment variables:
```rust
# #[macro_use] extern crate rocket;
use serde::{Serialize, Deserialize};
use figment::{Figment, providers::{Format, Toml, Serialized, Env}};
use rocket::fairing::AdHoc;
#[derive(Debug, Deserialize, Serialize)]
struct Config {
app_value: usize,
/* and so on.. */
}
impl Default for Config {
fn default() -> Config {
Config { app_value: 3, }
}
}
#[launch]
fn rocket() -> _ {
let figment = Figment::from(rocket::Config::default())
.merge(Serialized::defaults(Config::default()))
.merge(Toml::file("App.toml"))
.merge(Env::prefixed("APP_"));
rocket::custom(figment)
.mount("/", routes![/* .. */])
.attach(AdHoc::config::<Config>())
}
```
Rocket will extract it's configuration from the configured provider. This means
that if values like `port` and `address` are configured in `Config`, `App.toml`
or `APP_` environment variables, Rocket will make use of them. The application
can also extract its configuration, done here via the `Adhoc::config()` fairing.

## Configuring TLS
! warning: Rocket's built-in TLS is **not** considered ready for production use.
It is intended for development use _only_.
Rocket includes built-in, native support for TLS >= 1.2 (Transport Layer
Security). In order for TLS support to be enabled, Rocket must be compiled with
the `"tls"` feature. To do this, add the `"tls"` feature to the `rocket`
dependency in your `Cargo.toml` file:
```toml
[dependencies]
rocket = { version = "0.5.0-dev", features = ["tls"] }
```
TLS is configured through the `tls` configuration parameter. The value of `tls`
must be a table with two keys:
* `certs`: _[string]_ a path to a certificate chain in PEM format
* `key`: _[string]_ a path to a private key file in PEM format for the
certificate in `certs`
The recommended way to specify these parameters is via the `global` environment:
```toml
[global.tls]
certs = "/path/to/certs.pem"
key = "/path/to/key.pem"
```
Of course, you can always specify the configuration values per environment:
```toml
[development]
tls = { certs = "/path/to/certs.pem", key = "/path/to/key.pem" }
```
Or via environment variables:
```sh
ROCKET_TLS={certs="/path/to/certs.pem",key="/path/to/key.pem"} cargo run
```
