Subject [jira] [Commented] (CB-5403) Overhaul File API implementation
Date Thu, 30 Jan 2014 15:36:09 GMT


Ian Clelland commented on CB-5403:

In the end, the URLs used are of the form


This change was due to the {{filesystem}} scheme being handled specially by the Chrome-based
webview in Android 4.4; it is not possible to intercept requests for arbitrary {{filesystem://}}
URLs. iOS was changed to match for project-level consistency, although there is no technical
requirement for URLs to be consistent across platforms (or even across devices).

> Overhaul File API implementation
> --------------------------------
>                 Key: CB-5403
>                 URL:
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin File
>            Reporter: Ian Clelland
>            Assignee: Ian Clelland
> This is the meta-issue for all of the File API-related changes.
> File is getting overhauled, to provide the following features:
> 1. Entry.toURL() should return a filesystem:// URL on platforms which support it. Platforms
which cannot support custom URL protocols are free to return URLs which *can* be used to access
the local file system.
> 2. These URLs will look like:
>   filesystem://localhost/persistent/path/to/file.ext
>   filesystem://localhost/temporary/path/to/file.ext
> Additional roots are possible for new file systems (assets, media, documents, etc)
> (The specific format used does not need to conform to any existing or proposed standard,
since these URLs should not be assumed valid across machines)
> 3. Entry.fullPath will be relative to the HTML file system root, and not a path from
the root of the actual device file system.
> 4. Only URLs will be passed over the exec bridge; we won't be passing raw file system
paths into and out of JS anymore. (This generally means filesystem:// URLs in the iOS/Android
case, but platforms are free to support other URLs as needed)
> 5. Tests need to be updated so that they still pass when these changes are made.
> 6. File plugin should be modular, so that additional filesystem types can be easily supported.
