Bug 47310 – Implement FileEntrySync.file() in FileSystem API

• Component: WebCore Misc.

Implement FileEntrySync.file() in FileSystem API

[Kinuko Yasuda]

File::create() fails on workers on chromium because Worker's WebKitClient doesn't implement mimeTypeForExtension.  Should we just add the implementation for the method?  (That will proxy the call to the browser to access the mime registry.)

Yeah, I guess it just hasn't needed it up to this point.  Unless you see an alternative?

Why do you move file-from-file-entry.js from script-tests/ to resources/?

Because I wanted to use it both for workers and non-workers tests.

And I've included workers and resources directories to be synced under chrome/test/data... for chromium's workers tests but haven't done that for script-tests.

Please add a TODO to check size as well, once that's implemented.  Actually, is there a bug for that yet?

Updated to include the fix for 47563 (pass platform path).

We're calling AsyncFileSystem::virtualToPlatformPath in FileEntrySync. This seems some sort of confusing.

Added DOMFileSystem{,Sync}::createFile and changed FileEntry{,Sync}::file to call that method (as in createWriter).

Is this resource file only used in worker testing? If so, it would be better to put under filesystem/workers/resources. In addition, you can remove the check for the existence of importScripts.

Do we need to use "../resources"?

ditto.

> LayoutTests/fast/filesystem/workers/file-from-file-entry-sync-expected.txt:1
> +

Why do we have blank expected result here?

> WebCore/fileapi/DOMFileSystem.cpp:89
> +void DOMFileSystem::createFile(const FileEntry* file, PassRefPtr<FileCallback> successCallback, PassRefPtr<ErrorCallback>)

Please consider renaming 'file' argument to 'fileEntry' to avoid the confusion with the File being created in this method.

> WebCore/fileapi/DOMFileSystem.h:63
> +    void createFile(const FileEntry* file, PassRefPtr<FileCallback>, PassRefPtr<ErrorCallback>);

Please omit 'file' argument.

> WebCore/fileapi/DOMFileSystemSync.cpp:62
> +PassRefPtr<File> DOMFileSystemSync::createFile(const FileEntrySync* file, ExceptionCode& ec)

ditto.

> WebCore/fileapi/DOMFileSystemSync.h:59
> +    PassRefPtr<File> createFile(const FileEntrySync* file, ExceptionCode&);

ditto.

Makes sense, I put a FIXME comment for now - I'd like to file a separate issue to address this and keep it as is in this patch.

There're some other worker-only resources that are put under filesystem/resources and I want to move them in sync (and it requires chromoium test code change too).

Fixed.

Removed the line as this file doesn't depend on the file.

FileEntrySync => FileEntry
Please also update the expected result file.
