> Blackberry File plug-in issues creating files outside sandbox
> -------------------------------------------------------------
>
> Key: CB-4816
> URL: https://issues.apache.org/jira/browse/CB-4816
> Project: Apache Cordova
> Issue Type: Bug
> Components: BlackBerry, Plugin File
> Affects Versions: 3.0.0
> Reporter: David Peacock
> Assignee: Bryan Higgins
>
> I've updated to the latest file plug-in with the automatic un-sandbox changes
> when requesting a path outside the sandboxed area (these are in the dev
> branch today). However there are still some issues with this. I'm using
> blackberry.io to get the shared path where I know I should be able to write
> to.
> I've broken down the process of writing to a file in 5 steps at the bottom of
> this issue. First we get the file system, once we have that we get our
> directory - note we do this because we want to create a sub-folder if it's
> not already there, getFile does not permit this from what we can tell. When
> we get the directory, everything looks ok - we can see the sandbox flag is
> turned off. However, in step 3 when we go to get the file we simply pass in
> the name of the file as we are calling from the directory. The issue here is
> when we call getFile with the current logic it thinks it is sandboxed still.
> If you take a look at the DirectoryEntry.js file for
> DirectoryEntry.prototype.getFile you will notice it's checking the path
> parameter alone to determine whether it is sandboxed. It's not factoring in
> the currentPath into this equation. As a result, it goes into the else for
> sandbox disabled, sets the sandbox state to true, then tries to get the file
> using currentPath (which is outside the sandbox) as well as the path (file
> name passed in) and fails. It shouldn't be going into the else... really the
> fileUtils.isOutsideSandbox should be checking currentPath + "/" + path in
> this case.
> I think we need to ensure we are following the API documentation carefully,
> we need support both relative and absolute paths. Below are some snippets
> from the docs:
> getDirectory
> path: The path to the directory to be looked up or created. Either an
> absolute path, or a relative path from this DirectoryEntry. (DOMString)
> getFile
> path: The path to the file to be looked up or created. Either an absolute
> path, or a relative path from this DirectoryEntry. (DOMString)
> In my opinion this means the logic in DirectoryEntry.js for getDirectory and
> getFile should be updated. The first thing we should do is check to see if
> the path is absolute, i.e. the first char is "/" - if it is, we shouldn't be
> using the currentPath here at all I would think? I made some minor updates
> to this logic locally and it is working now - at least for how we use it! I
> will be making a pull request to GitHub shortly for this.
> Below is a snippet of how we were trying to write to a file:
> //Assuming you have blackberry.io plug-in and cordova file plug-in
> installed...
> function FileManager() {}
> FileManager.fileDir = blackberry.io.sharedFolder + "/documents/test/";
> FileManager.fileName = "test.txt";
> // Step 1 - Get file system
> window.requestFileSystem(LocalFileSystem.TEMPORARY, 0,
> FileManager.gotWriteFS, null);
> //Step 2 - Get the directory
> FileManager.gotWriteFS = function (fileSystem) {
> //Get/Create the directory we want to use
> fileSystem.root.getDirectory(FileManager.fileDir, {
> create: true,
> exclusive: false
> }, FileManager.gotWriteDirEntry, null); };
> //Step 3 - Get the file
> FileManager.gotWriteDirEntry = function (dirEntry) {
> //Get the file from the current directory
> dirEntry.getFile(FileManager.fileName, {
> create: true,
> exclusive: false
> }, FileManager.gotWriteFileEntry, null); };
> //Step 4 - Create a writer
> FileManager.gotWriteFileEntry = function (fileEntry) {
> fileEntry.createWriter(FileManager.gotFileWriter, null); };
> //Step 5 - Write the data
> FileManager.gotFileWriter = function (writer) {
> writer.write("something to write");
> };
