2004-01-28 Michael Natterer <mitch@gimp.org> Added infrastructure to make sure we don't write to the global brush, pattern etc. directories. Needed to make this configurable because we can't rely on the global directories being read-only, having certain names or being otherwise detectable at runtime in a sane way. Fixes bug #132214. * libgimpbase/gimpdatafiles.[ch]: added "const gchar *dirname" to the GimpDataFileData struct so callbacks don't need to call g_path_get_dirname() for each file. * libgimpwidgets/gimpfileentry.c: made it work with non UTF-8 encoded filenames. * libgimpwidgets/gimppatheditor.[ch]: ditto. Added GUI and API for setting/getting a second "writable_path". The widget makes sure that the writable_path is always a subset of the path. * app/config/gimpconfig-utils.[ch]: added new function gimp_config_build_writable_path(). * app/config/gimpcoreconfig.[ch]: added separate properties for the writable brush, pattern, gradient, palette and font paths. * app/config/gimprc-blurbs.h: added (still empty) blurbs for the new properties. * app/core/gimpdata.[ch] (gimp_data_set_filename): added parameter "gboolean writable". Set data->writable to FALSE by default. If "writable" is passed as TRUE, still check if we can write to the file before setting data->writable to TRUE. (gimp_data_create_filename): changed "data_path" parameter to "dest_dir" and assume dest_dir is writable. (gimp_data_duplicate): set data->dirty to TRUE to make sure duplicated things will be saved. * app/core/gimpbrush.c * app/core/gimpbrushgenerated.c * app/core/gimpbrushpipe.c * app/core/gimpgradient.c * app/core/gimppalette.c * app/core/gimppattern.c: don't set the data's filename and don't touch data->dirty in the _load() functions because that's done by the data factory now. Don't touch data->dirty in the _duplicate() functions because that's done by gimp_data_duplicate() itself now. * app/core/gimpdatafactory.[ch] (gimp_data_factory_new): added "writable_property_name" and remember it. Added utility function gimp_data_factory_get_save_dir() which determines the directory to save new datas to. Added public function gimp_data_factory_data_save_single() which saves a single data object. Make sure new things get saved to the first writable directory as specified in preferences. * app/core/gimp.c (gimp_real_initialize): pass the writable_paths' property names to gimp_data_factory_new(). * app/widgets/gimpdataeditor.c (gimp_data_editor_save_dirty): use gimp_data_factory_data_save_single() instead of implementing saving here. * app/widgets/gimppropwidgets.[ch] (gimp_prop_path_editor_new): added "const gchar *writable_property_name" parameter (can be NULL). Added the needed callbacks to handle the writable_path and made the path_editor and file_entry code aware of non UTF-8 filename encodings. Some general cleanup. * app/gui/preferences-dialog.c: changed accordingly.
