====== Progress on ThunarVFS References in Thunar ======

... or: which ones are left.

===== Thunar =====

ThunarVFS is used almost everywhere inside Thunar. All appearances in the code have to be replaced
with equivalent (or improved) implementations based on GIO. In order to do that, we first have to
collect information about all the ThunarVFS references in the code. Afterwards, we can determine
what to do with each reference. 

It's probably a good idea to look at ThunarFolder/ThunarFile at the very end because I already
have an idea on how to deal with them. Deciding what to do with the other ThunarVFS references
first could have interesting implications on ThunarFolder/ThunarFile.

==== ThunarFile ====

Each instance of the ''ThunarFile'' class represents one file/node in the filesystem. It wraps
both ''ThunarVfsPath'' and ''ThunarVfsInfo'' with a huge number of convenience functions and macros.

Of course all these functions could easily be ported to GIO. A number of function signatures
will have to be changed to get rid of ThunarVFS references. However, we have to do something about
blocking ''GFileInfo'' queries inside ''ThunarFile''.

First of all, the constructor should be split up from

  ThunarFile *thunar_file_get_for_info (ThunarVfsInfo       *info);
  ThunarFile *thunar_file_get_for_path (ThunarVfsPath       *path, 
                                        GError             **error);
  ThunarFile *thunar_file_get_for_uri  (const gchar         *uri,
                                        GError             **error);

into something like this:

  ThunarFile *thunar_file_get          (GFile               *file);
  gboolean    thunar_file_load         (ThunarFile          *file,
                                        GCancellable        *cancellable,
                                        GError             **error);

Maybe alternatively add an asynchronous way to load files:

  void        thunar_file_load_async   (ThunarFile          *file,
                                        GCancellable        *cancellable,
                                        GAsyncReadyCallback *callback,
                                        gpointer             user_data);
  gboolean    thunar_file_load_finish  (ThunarFile          *file,
                                        GAsyncResult        *result,
                                        GError             **error);
  gboolean    thunar_file_is_loaded    (ThunarFile          *file);

==== main.c ====

Has references to

  * ''thunar_vfs_init()''
  * ''thunar_vfs_shutdown()''

=== Solution ===

Make sure to setup GIO correctly by following these steps:

  - More?

===== Thunarx =====

Thunarx has a few references to ThunarVFS in ''ThunarxFileInfo'' which have to be replaced 
with GIO equivalents:

  * ''ThunarVfsInfo *thunarx_file_info_get_vfs_info (ThunarxFileInfo *file_info)''
  * ''ThunarVfsInfo *(*get_vfs_info) (ThunarxFileInfo *file_info)'' in ''ThunarxFileInfoIface''

===== Thunar Extensions =====

There is a number of extensions for Thunar, like

  * [[http://goodies.xfce.org/projects/thunar-plugins/thunar-media-tags-plugin|Thunar Media Tags Plugin]]
  * [[http://goodies.xfce.org/projects/thunar-plugins/thunar-thumbnailers|Thunar Thumbnailers]]

Most of them have references to ThunarVFS or rely on ThunarVFS to work (as is the case with 
thumbnailers which don't support GIO). 

===== Thunar Volume Manager ====

thunar-volman uses ThunarVFS everywhere and will have to be ported to GIO as well.
