Subject [jira] [Created] (CB-6148) wrong filesystem properties in entry after moveTo()
Date Sun, 02 Mar 2014 21:37:30 GMT
Dominik Pesch created CB-6148:
---------------------------------

             Summary: wrong filesystem properties in entry after moveTo()
                 Key: CB-6148
                 URL: https://issues.apache.org/jira/browse/CB-6148
             Project: Apache Cordova
          Issue Type: Bug
          Components: Plugin File
    Affects Versions: 3.3.0
         Environment: iOS6
iOS7
            Reporter: Dominik Pesch


To store pictures persistent in our app, we move the image files from the temporary folder
to the persistent folder. The code breaks after upgrading to Cordova 3.4.0 and file plugin
1.0.0 (and 1.0.1).

We've found that the filesystem object in the moveTo success callback entry parameter has
got wrong value (please notice pseudo code below). 

Below you'll see the Xcode log output:

*Our problem:*
We had expected that newFileEntry.filesystem.name has to be 'persistent' (instead it is 'temporary')
and newFileEntry.filesystem.fullPath as '/pics/' (but we've got 'undefined').

{code:JavaScript|title=Shortened pseudo code:|borderStyle=solid}
// ... will be called from navigator.camera.getPicture(...)
function picSuccess(imageUrl)
{
  window.resolveLocalFileSystemURL(imageUrl, _fileEntrySuccess, _handleFileError);

  function _fileEntrySuccess(tmpFileEntry)
  {
    var newFileName = "pic" + new Date().getTime() + '.jpg';

    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys)
    {
      console.log("fileSys.name: " + fileSys.name);
      console.log("fileSys.root.name: " + fileSys.root.name);
      console.log("fileSys.root.fullPath: " + fileSys.root.fullPath);

      fileSys.root.getDirectory("pics", { create: true, exclusive: false }, function(dir)
      {
        console.log("dir.name: " + dir.name);
        console.log("dir.fullPath: " + dir.fullPath);

        tmpFileEntry.moveTo(dir, newFileName, function(newFileEntry)
        {
          console.log("newFileEntry.name: " + newFileEntry.name);
          console.log("newFileEntry.fullPath: " + newFileEntry.fullPath);
          console.log("newFileEntry.nativeURL: " + newFileEntry.nativeURL);
          console.log("newFileEntry.toUrl(): " + newFileEntry.toURL());
          console.log("newFileEntry.filesystem.name: " + newFileEntry.filesystem.name);
          console.log("newFileEntry.filesystem.fullPath: " + newFileEntry.filesystem.fullPath);

          _fileMovedSuccess(newFileEntry);
        }, _handleFileError)
      })
    },
    _handleFileError);
  }


  function _fileMovedSuccess(entry)
  {
    // ...
  }
}
{code}

We've tested this with Cordova 3.4.0 and cordova file plugin 1.0.0 and 1.0.1 (https://github.com/apache/cordova-plugin-file.git
