Describe the bug

After installing watchman and opening a golang project, an error occurs when I use :w command to save file. And then it does not happen after removing watchman.

watchman version:

> watchman --version
2023.01.30.00

Can't reproduce, do you have any autocmd for saving? I don't find in your vimrc.

There is no error info when I try to open a small project, it is may be affected by the size of project ~

pattern is too long

Looks like this error came from glob, properly watchman checks long pattern in big project.

[fannheyward]

TypeError: pattern is too long

1. language server will register watcher with globPattern, you can get this from the trace logs, for gopls, it want to watch go/mod/work files changes:

                "watchers": [
                    {
                        "globPattern": "**/*.{mod,work}",
                        "kind": 7
                    },
                    {
                        "globPattern": {
                            "baseUri": "file:///Users/fannheyward/src/test",
                            "pattern": "**/*.{go,mod,sum,work}"
                        },
                        "kind": 7
                    }
                ]

2. coc.nvim create a fileWatcher with watchman to watch files in project changes
3. watchman detected any file changes, coc.nvim uses minimatch to filter them with the globPattern, then fire file deleteEvent/createEvent/renameEvent etc

The issue is came from the minimatch step: minimatch limited the MAX_PATTERN_LENGTH, we got the pattern is too long error in big project.

We don't have any way to prevent this in coc.nvim side for now, maybe it's better to disable watchman in big project. Close for now.
