[Cctools-cchost] About virtual deletion

[Snic H. <jms...@gm...>]

Hi Jon, sometimes we need know who had uploaded file,  when user had deleted
file. So, we have to save file metadata.
I have written some code for the above requirement. When admins or users
delete file, the metadata of file is kept in database.
I commits some files as follow:

1. ccextras/update_v_5_virtual_delete.inc
adding a new field of cc_tbl_files, which is 'file_virtual_delete.'
adding a new field of cc_tbl_uploads, which is 'upload_virtual_delete.'

2. ccextras/cc-virtual-delete.inc
global setup for virtual deletion

3. ccextras/cc-virtual-delete.php
global setup for virtual deletion

4. patch cclib/cc-uploadapi.php
if $CC_GLOBALS['virtual_delete'] then virtual deletion

5. patch cclib/cc-upload-table.php
don't display file by virtual deleted.

6. patch cclib/cc-admin.php
when admins disable the function that "virtual deletion", all file by
virtual deleted will delete.

What do you think?

Thanks.
Snic
