derive_builder has some extra dependencies that take a while to compile.
The builder feature can be expressed via a 30-line macro. So let's do
that to make termwiz compile faster.
The palette crate has a codegen step that translates svg_colors.txt to named.rs.
That makes it hard to build using buck.
Remove the palette dependency so termwiz is easier to build using buck.
I made sure the following code:
fn main() {
use termwiz::color::RgbColor;
let r = RgbColor::from_rgb_str("#02abcd").unwrap();
let r1 = r.to_tuple_rgba();
let r2 = r.to_linear_tuple_rgba();
println!("r1 = {:?}", r1);
println!("r2 = {:?}", r2);
}
prints
r1 = (0.007843138, 0.67058825, 0.8039216, 1.0)
r2 = (0.000607054, 0.4072403, 0.6104956, 1.0)
before and after the change.
Change build.rs codegen to const_fns. This makes vtparse more friendly for buck
build.
Note const_fn functions still have limitation on the current stable (1.41)
rustc (ex. native "match" or "if" cannot be used in const_fn). So I used some
tricks to get it compile.
This helps to restore any individually dropped tabs and to detect
tabs that were created by other clients across a reconnection.

This is useful for setting up a reasonable initial environment.
For example, on Windows you might want to set the `prompt` environment
so that some basic shell integration is enabled; this will cause new
tabs to open with the same cwd as the current tab:
```
set_environment_variables = { "prompt"="$E]7;file://localhost/$P$E\\$P$G" }
```
This setting is intended to apply only to the local domain.

This allows this prompt setting to work:
```
prompt $E]7;file://localhost/$P$E\$P$G
```
although this one sets it for future prompts:
```
setx prompt $E]7;file://localhost/$P$E\$P$G
```

Embed rgb.txt and parse it on the fly to produce the list of colors.
This list is a superset of palette's SVG color list.

This is conceptually slightly cleaner and allows sessionhandler to
be agnostic of the details of the channel used to communicate with
the client; it just has a Sender<DecodedPdu> to work with.
I suspect some race condition because adding these made the connect
time hang stop reproducing for me on my local network.
Will try this to the corp vpn.

This commit adjusts the features in Cargo.toml to allow building
without openssl on unix systems.
It teaches the native_tls flavor of the code to perform bootstrapping
via ssh, but is still not usable because there still isn't a way
to get native_tls to use PEM files.
This makes the tls channel much easier to use; the config can now be as
simple as this on the server side:
```toml
[[tls_servers]]
bind_address = "192.168.1.8:8080"
```
and this on the client side:
```
[[tls_clients]]
name = "hostname"
bootstrap_via_ssh = "192.168.1.8"
remote_address = "hostname:8080"
```
and then `wezterm connect hostname` will use ssh to connect to the
host, start the mux server, request the CA and client certs and
then connect to it over TLS.
This is implemented only for openssl at the moment.
If we're actively outputting to the window and the user closes it,
we don't need to panic.
Make the window a little larger now that it shows more data.
Adds a default 60 second timeout for read and write for the tls
and unix domain sockets that we create. This applies to ssh
domains, but not `wezterm ssh` sessions that go direct to ssh ptys.
I noticed that the reconnection UI for TLS mux sessions was annoying
on macOS: it would flash up and steal the focus, make a connection
attempt that would immediately fail because the destination was not
routable and then close the window. It would do this each time
a connection attempt was made (every few seconds in the early
stages of backoff).
This commit pulls the UI up a level so that we open the window at
the start of the connection (or re-connection) attempt, and keep
the same one for its lifetime.
This also introduces a headless UI object that doesn't output or
respond to anything. You can set the log level to trace to see
what is happening inside. It is used by the CLI mode. It could
perhaps be made smart enough to conditionally show a UI when needed,
but since it is targeting local unix domain sockets, that doesn't
seem like it is needed right now.
At some recent point in history, I effective broke multiple tabs in
`wezterm ssh HOST` by allowing them to contend in weird ways on locks,
leading to a horribly sluggish experience where multiple keypresses
in alternate tabs would appear to be swallowed until IO happened in
another tab. Yuk!
This commit fixes that up by teaching channels how to wait cooperatively
and to attempt a read in all waiting channels when the fd becomes
readable.
I'm adding this primarily to avoid repeatedly showing "No more
fallbacks" errors when moving the mouse over a terminal that contains
cells with no matching glyphs.
It has the nice side effect of changing the typical opengl tab render
time from ~2.9ms to ~1.3ms.
