The core improvement is that `Rocket::launch()` now resolves to
`Ok(Rocket<Ignite>)` on nominal shutdown. Furthermore, shutdown never
terminates the running process.
Other changes directly related to shutdown:
* Runtime worker thread names are now irrelevant to graceful shutdown.
* `ErrorKind::Runtime` was removed; `ErrorKind::Shutdown` was added.
* The `force` config value is only read from the default provider.
* If `force`, Rocket's constructed async runtime is terminated.
Other related changes:
* The exported `hyper` module docs properly reflect public re-exports.
The previous implementation allowed a trivial DoS attack in which the
client need simply maintain open connections with incomplete handshakes.
This commit resolves that by allowing a server worker to progress as
soon as a TCP connection has been established. This comes at the expense
of a more complex implementation necessitated by deficiencies in Hyper.
Potentially resolves#2118.
Previously, the heartbeat message, in its raw form, was ":\n\n". This
commit changes the message to be ":\n".
The former message, when parsed as Server-Sent Events, contained an
empty comment (as desired) _and_ a new line (erroneously). The new line
resulted in emitting any event that was presently being emitted, even if
it wasn't complete. That is, emitting an event partly, such as the
event's data but not its name. Removing the extra new line resolves this
issue and ensures that events aren't interrupted by the heartbeat.
Fixes#2152.
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.
In cc98f98, logging was changed to use a new 'write_out!' macro that
internally used 'write!' instead of 'print!' to log. This had an
unfortunate side-effect: 'libtest' via 'cargo test' no longer captures
the log output of tests.
The reason this occurs is due to the way that Cargo, or rather
`libtest`, captures log output: it uses hidden, unstable functions that
replace a special sink that `print!`, and _only_ `print!` writes to.
Using `write!` directly, as the commit does, bypasses this sink, and so
`cargo` never captures the output.
As a compromise, we only use the better implementation when we're not
compiled with `debug_assertions` or running tests, so at least tests run
in debug-mode won't spew output.
Also updates 'tokio-rustls' to a compatible version.
Additionally depends on 'rustls-pemfile' which includes functionality
that was previously part of 'rustls' itself.
This commit removes the 'CookieJar::get_private_pending()' method in
favor of the already existing and correct 'CookieJar::get_pending()'
method. Previously, the 'CookieJar::get_private_pending()' method
attempted to decrypt the value of a pending cookie, which in reality is
plaintext, thus failing. Because the pending value is plaintext, the
'CookieJar::get_pending()' method suffices.
Documentation has been updated to refer to 'CookieJar::get_pending()'.
Fixes#2063.
The primary aim of this commit is to reduce confusion between
'content::Json' and 'rocket::serde::json::Json' be renaming the former
to 'content::RawJson'. The complete changes in this PR are:
* All responders in the 'content' module are prefixed with 'Raw'.
* The 'content::Custom' responder was removed entirely.
* The 'Plain' responder is now 'RawText'.
* The 'content' API docs point to the 'serde' responders.
* The docs and examples were updated accordingly.
Previously, TLS, via 'Config::tls', was configurable even if the 'tls'
feature was disabled. This commit changes this so that the 'Config::tls'
field and TLS config structures are only available if 'tls' is enabled.
