--------------------------------
Summary: FileSystem objects are not JSON-serializable
Key: CB-6352
URL: https://issues.apache.org/jira/browse/CB-6352
Project: Apache Cordova
Issue Type: Bug
Components: Plugin File
Reporter: Ian Clelland
Assignee: Ian Clelland
Attempting to render a FileSystem object (or a FileEntry, or DirectoryEntry, or
any other object with a FileSystem contained it) results in the error:
{code}
TypeError: JSON.stringify cannot serialize cyclic structures.
{code}
(This is new behaviour with File 1.0.0)
This happens because of a cycle in the FileSystem object structure: FileSystem
contains a 'root' property, which is a DirectoryEntry. The DirectoryEntry
contains a 'filesystem' property, which is the original FileSystem.
I think that we can solve this with a {{.toJSON()}} method on the FileSystem
object. This is supported (tested) on iOS and Android, and appears to be
present in all versions of WebKit back to 2009. I don't believe that the
presence of this method should have any side effects on webviews (if there are
any) which do not support it.
