Infinite watch loop on Windows

[torhovland]

I'm getting the infinite watch loop decribed in #84 and #99. My setup is:

Windows 10 Build 19042.804.

rustup-init using the following defaults:

default host triple: x86_64-pc-windows-msvc
default toolchain: stable (default)
profile: default
modify PATH variable: yes

Visual Studio 2019 - 16.8.6, with the C++ desktop development workload.

rustup target add wasm32-unknown-unknown
cargo install --locked trunk
cargo install wasm-bindgen-cli

At this point I have:

rustup 1.23.1 (3df2264a9 2020-11-30)
rustc 1.50.0 (cb75ad5db 2021-02-10)
cargo 1.50.0 (f04e7fab7 2021-02-04)
wasm-bindgen 0.2.70
trunk 0.8.2

Running trunk watch on either trunk/examples/seed or trunk/examples/yew yields the infinite watch loop.

I did some debug logging in here:

        if ev_path
            .ancestors()
            .any(|path| self.ignored_paths.iter().any(|ignored_path| { 
                if ignored_path == path {
                    self.progress.println(format!("Ignored {:?}", path));
                } else {
                    self.progress.println(format!("{:?} !== {:?}", ignored_path, path));
                }
                ignored_path == path }))
        {
            return; // Don't emit a notification if path is ignored.
        }

I found this:

Handling Write("\\\\?\\C:\\Projects\\trunk\\examples\\seed\\target\\wasm-bindgen\\debug\\index-88a2d670d6306bab_bg.wasm")

"\\\\?\\C:\\Projects\\trunk\\examples\\seed\\dist" !== "\\\\?\\C:\\"
"C:\\Projects\\trunk\\examples\\seed\\target" !== "\\\\?\\C:\\"
Not ignored.

So the problem seems to be this inequality:

"C:\\Projects\\trunk\\examples\\seed\\target" !== "\\\\?\\C:\\Projects\\trunk\\examples\\seed\\target"
