HTML5 Filesystem API doesn't work

[tarruda]

package.json:

{
  "name": "html5-fs-fail",
  "main": "http://html5-demos.appspot.com/static/filesystem/filer.js/demos/index.html",
  "chromium-args": "--enable-logging=stderr"
}

Opening the page will show 0 bytes of free space and something like this on console: "WARNING:chrome_quota_permission_context.cc(287)] Attempt to request quota from a background page". Chrome shows about 10mb when the user gives permission.

Something else to consider: Chrome asks the user if the app should allow filesystem API access, but for nw.js there should probably be an user-provided callback to decide based on URL.

I thought nwjs allows any requested quota but you have to actually request a quota. I've got HTML5 filesystem working well on 0.16.1 using cordova-promise-fs which simply uses code like this:

navigator.webkitPersistentStorage.requestQuota(storageSize, function(grantedBytes) {
   window.requestFileSystem(type, grantedBytes, resolve, reject);
}, ...

Reproduced on Linux/Windows with nwjs-sdk-0.21.2.

@Christywl how did you reproduce it? it should be working ...

I just used the package.json in the bug.
Log in console:
[10416:10416:0315/062554.429536:WARNING:chrome_quota_permission_context.cc(287)] Attempt to request quota from a background page: 3,7

In browser the user will have to approve the usage. In NW the application needs to apply for quota first as @timfish said.

We could add a callback as reporter proposed, or just let it pass first to make it easier for newcomers.

changed the default setting to allow quota in git. Will be available in the next nightly build.
