Mahmoud Al-Qudsi 55b654ebd1 Leak `remote` instead of wrapping it in an `Arc` 
The `Arc<string>` lived as long as the server in all cases, but this way we
don't have to pay any cache invalidation/coherence costs associated with
constantly incrementing and decrementing the atomic reference count.

Mahmoud Al-Qudsi 84ed909836 Log errors establishing upstream connection 
The result bubbled up to tokio::spawn() wasn't actually being reported anywhere.

Mahmoud Al-Qudsi ca67fd31ca Don't report ECONNABORT or ECONNRESET as read errors 
If we're just idle waiting for bytes to become available to read and the
connection is forcibly reset or aborted, just treat it as if it were closed
normally. This lets us bubble back the actual number of bytes transmitted.

We are still treating these as errors if we encounter them while actively trying
to write to the host/client.

Should resolve https://github.com/mqudsi/tcpproxy/issues/3

Mahmoud Al-Qudsi 80c529b020 Drop tokio feature "parking_lot" 
It's no longer needed with the improvements to the locks in the standard
library.

Mahmoud Al-Qudsi d520400413 Abort the other half of a connection regardless of Ok/Err 
Previously we were only sending an abort signal on successful completion of one
half of a proxied connection and relying on errors to also affect the other
half.

Now we explicitly send an abort after completing with one half of a connection
regardless of whether we did that successfully or with an error.

Mahmoud Al-Qudsi 0164ef836a Aggressively terminate half-closed connections 
Previously, if the client closed after receiving a reply, a keepalive connection
to the server would stick around until the timeout, even though we will never
reuse it.

Mahmoud Al-Qudsi b2c2876d03 Upgrade to the latest version of tokio 
Also simplify the code by dropping our own async resolution, since the newer
tokio can do that for us.
 2022-06-30 16:51:50 -05:00
Mahmoud Al-Qudsi 677b6cd33a Make options easier to use 
The local port is now optional, in which case a random free port will be used
(and reported in the output). The `--host` argument is now `--remote-host`.

Mahmoud Al-Qudsi 0e99ab0eb6 Just some minor cleanup 2017-08-14 00:34:41 -05:00
Mahmoud Al-Qudsi 49aee2300b Handle being provided an IP and not a hostname 
This was insanely hard not due to anything other than lack of
familiarity with futures-rs. It's unfortunate that so much of being able
to use it correctly requires knowledge of futures-rs and not rust
itself. e.g. it is not possible to implement this solution with pattern
matching, usage of futures::future::result() is instead required.

Mahmoud Al-Qudsi 62651197d5 Thread-free design, using tokio core for asynchronous proxying 
No longer spawing two threads for each connection, now using tokio
core to use async network connections which should make this scale
beautifully.
