# Description
Relative: #8060
While investigating, I found we need to update notify, which is a good
step to remove some duplicate dependencies.
As title, here are some goods and bads after updating:
## Good
keep dependency up to date, and remove duplidate dependency(cfg-if,
winapi) in Cargo.lock.
## Bad
Introduce some breaking changes:
After updating to notify v5, I found that we have to remove `Rename`
events.
But I've testing under notify v4, and it doesn't work good if we running
the following command on MacOS:
```
touch a
mv a b
```
It fires file create event, but no file rename event. So `rename` event
is not really reliable, so I think it's ok for us to remove `Rename`
events.
The reason to remove `--debounce-ms` flag:
It's not provided by defualt file watcher, we can use
[PollWatcher](https://docs.rs/notify/latest/notify/poll/struct.PollWatcher.html),
but it scans filesystem, which is really expensive. So I just remove the
flag.
# User-Facing Changes
1. `--debounce-ms` flag is removed
2. no longer watch `Rename` event.
# Tests + Formatting
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
# After Submitting
If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
