ResourcePath.copytree fails for directory inside compressed package

[rchl]

I have package LSP-eslint.sublime-package with file structure like:

/vscode-eslint/
/vscode-eslint/server.js
/vscode-eslint/more_files
/plugin.py

I'm trying to copy whole vscode-eslint directory to cache directory with:

source_resource_path = 'Packages/LSP-eslint/vscode-eslint/'
target_path = os.path.join(sublime.cache_path(), 'LSP-eslint', 'server')
sublime_lib.ResourcePath(source_resource_path).copytree(target_path, exist_ok=True)

That fails with:

Traceback (most recent call last):
  File "/Users/me/Library/Application Support/Sublime Text 3/Packages/sublime_lib/st3/sublime_lib/resource_path.py", line 521, in read_bytes
    return sublime.load_binary_resource(str(self))
  File "/Applications/Sublime Text.app/Contents/MacOS/Lib/python33/sublime.py", line 244, in load_binary_resource
    raise IOError('resource "%s" not found' % name)
OSError: resource "Packages/LSP-eslint/vscode-eslint" not found

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Applications/Sublime Text.app/Contents/MacOS/Lib/python33/sublime_plugin.py", line 478, in on_api_ready

    sublime_lib.ResourcePath(local_server_path).copytree(server_cache_directory_path, exist_ok=True)
  File "/Users/me/Library/Application Support/Sublime Text 3/Packages/sublime_lib/st3/sublime_lib/resource_path.py", line 608, in copytree
    resource.copy(file_path)

    data = self.read_bytes()
  File "/Users/me/Library/Application Support/Sublime Text 3/Packages/sublime_lib/st3/sublime_lib/resource_path.py", line 523, in read_bytes
    raise FileNotFoundError(str(self)) from err
FileNotFoundError: Packages/LSP-eslint/vscode-eslint

It works fine when package is unpacked.
It works (I believe) to get all subresources with .glob('**') and copy them one-by-one but it fails trying to copy contents of directory with copytree.

I've tried sublime_lib.ResourcePath(source_resource_path).rglob('*') since that's what copytree is using and got this result:

[ResourcePath('Packages/LSP-eslint/vscode-eslint'), ResourcePath('Packages/LSP-eslint/vscode-eslint/.DS_Store'), ResourcePath('Packages/LSP-eslint/vscode-eslint/.eslintignore'), ResourcePath('Packages/LSP-eslint/vscode-eslint/.eslintrc.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/diff.js'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/diff.js.map'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/eslintServer.js'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/eslintServer.js.map'), ResourcePath('Packages/LSP-eslint/vscode-eslint/package-lock.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/package.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/diff.ts'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/eslintServer.ts'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/thenable.d.ts'), ResourcePath('Packages/LSP-eslint/vscode-eslint/tsconfig.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/webpack.config.js')]

I think the issue is that the list of resources includes the root directory itself. Since glob is **/*, it probably shouldn't.

[rchl]

With uncompressed package and the same command, the list doesn't include root directory:

[ResourcePath('Packages/LSP-eslint/vscode-eslint/.DS_Store'), ResourcePath('Packages/LSP-eslint/vscode-eslint/.eslintignore'), ResourcePath('Packages/LSP-eslint/vscode-eslint/.eslintrc.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/package-lock.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/package.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/tsconfig.json'), ResourcePath('Packages/LSP-eslint/vscode-eslint/webpack.config.js'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/diff.js'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/diff.js.map'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/eslintServer.js'), ResourcePath('Packages/LSP-eslint/vscode-eslint/out/eslintServer.js.map'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/diff.ts'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/eslintServer.ts'), ResourcePath('Packages/LSP-eslint/vscode-eslint/src/thenable.d.ts')]
