Subject [jira] [Commented] (CB-930) DirectoryReader creates null error code for inaccessible directory
Date Tue, 19 Jun 2012 14:43:43 GMT

    [ https://issues.apache.org/jira/browse/CB-930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13396825#comment-13396825

Simon MacDonald commented on CB-930:
------------------------------------

Yeah, for some reason my three Samsung devices will not let me move an app to the SD Card
in order to create this directory. I've done a code review and I can't see why the error code
would be set to null. All of the error codes look like they are getting set correctly. I need
to get ahold of a device where I can debug this.

> The error callback should follow the FileError specification which defines e.g. SECURITY_ERR=2
as error code. When I try to access file:///mnt/sdcard/.android_secure which is protected
by the OS, I get the error code null.
> Example to reproduce (using Android 4.0 emulator):
> document.addEventListener("deviceready", function() {
>     window.requestFileSystem(
>         LocalFileSystem.PERSISTENT,
>         0,
>         function(fileSystem) {
>             var reader = fileSystem.root.createReader().readEntries(function(entries)
{
>                 for(var i = 0; i < entries.length; ++i)
>                     if(/\.android_secure$/.test(entries[i].fullPath))
>                         entries[i].createReader().readEntries(function(entries) {
>                             for(var i = 0; i < entries.length; ++i) {
>                                 if(entries[i].isDirectory)
>                                     console.log("dir " + entries[i].fullPath)
>                                 else
>                                     console.log("file " + entries[i].fullPath)
>                             }
>                         }, function(err) {
