This tweaks the tokio runtime checker (only used in debug mode) in
order to use a single thread.
Performing the CPUs auto-detection step on each check adds significant
syscall-tracing noise and runtime latency. This completely skips it.
The "socks" feature has been removed for a while now, the optional
dependency on the "socks" crate commented out.
The code for actually providing the socks feature was, however, still
mostly present, if a bit out of date.
This commit re-adds the socks feature using the tokio-socks (instead of
socks) crate.
Closes#620
To allow for the default-tls to change to a different backend by
default, this adds a new `native-tls` optional feature. Any TLS feature
that was only available using native-tls now requires the `native-tls`
feature to be enabled.
Changed the redirect types to be from the `redirect` module:
- `reqwest::RedirectPolicy` is now `reqwest::redirect::Policy`
- `reqwest::RedirectAttempt` is now `reqwest::redirect::Attempt`
- `reqwest::RedirectAction` is now `reqwest::redirect::Action`
Changed behavior of default policy to no longer check for redirect loops
(loops should still be caught eventually by the maximum limit).
Removed the `too_many_redirects` and `loop_detected` methods from
`Action`.
Added `error` to `Action` that can be passed any error type.
Closes#717
Add several lines that explain the usage of proxies in the current
version. Introduce the familiar HTTP(S)_PROXY syntax so often seen
in http(s) clients.
Closes#685
If no proxies are configured for a client, the environment (system) will
be inspected automatically to set up proxies.
Configuring a `Proxy` on a client or calling `no_proxy` will disable the
use of the automatic system proxy.
Closes#403
