filesystem_access(path, action = :write, &block)

public

Rescues permissions errors raised by file system operations (ie. Errno:EACCESS, Errno::EAGAIN) and raises more friendly errors instead.

@param path [String] the path that the action will be attempted to @param action [Symbol, #to_s] the type of operation that will be

performed. For example: :write, :read, :exec

@yield path

@raise [Bundler::PermissionError] if Errno:EACCES is raised in the

given block

@raise [Bundler::TemporaryResourceError] if Errno:EAGAIN is raised in the

given block

@example

filesystem_access("vendor/cache", :write) do
  FileUtils.mkdir_p("vendor/cache")
end

@see {Bundler::PermissionError}
