Add support for having obsolete data resources. An obsolete resource
is not shown in the UI or managed in any way, but it will be
considered when plug-ins requests resources. This in order to maintain
backwards compatibility for plug-ins.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.
svn path=/trunk/; revision=27913
2008-07-10 Sven Neumann <sven@sven-sun.berlin.jpk.com>
* app/core/gimpdata.[ch]: renamed gimp_data_name_compare() to
gimp_data_compare() and changed it to keep the data in three
groups: internal, writable and system resource files. Inside the
groups the sorting order is alphabetical.
* app/core/gimpdatafactory.c (gimp_data_factory_new): changed
accordingly.
svn path=/trunk/; revision=26100
2008-02-05 Martin Nordholts <martinn@svn.gnome.org>
Applied patch from Olof Frahm which makes loading of data
files (brushes and so on) happen recursively (bug #514160).
* app/core/gimpdatafactory.c
(gimp_data_factory_data_load): Recursively search sub directories
for data files using the new helper function
(gimp_data_factory_load_data_recursive)
svn path=/trunk/; revision=24814
2007-06-14 Michael Natterer <mitch@gimp.org>
* app/core/gimpdatafactory.c (gimp_data_factory_data_foreach):
remove calls to container_freeze() and container_thaw()
(gimp_data_factory_data_reload)
(gimp_data_factory_data_free): add them here instead.
(gimp_data_factory_data_save): remove freeze/thaw calls here
without any replacement. The list doesn't change by saving its
items. Fixes insanely long quit time when there are many data
objects.
svn path=/trunk/; revision=22778
2007-06-03 Michael Natterer <mitch@gimp.org>
* app/core/gimpdatafactory.c (gimp_data_factory_load_data): check
for errors even if the loader_func returned something so we
display errors from partially loaded files which contain multiple
data items.
svn path=/trunk/; revision=22696
2007-03-09 Michael Natterer <mitch@gimp.org>
* app/core/core-types.h: include "libgimpmath/gimpmathtypes.h"
instead of "libgimpmath/gimpmath.h".
* app/core/gimpbrush.h
* app/paint/gimppaintcore.h
* app/paint/gimpperspectiveclone.h
* app/text/gimptext.h

gimpmatrix.h explicitely where they are needed in public structs.
* app/*/*.c
* tools/pdbgen/pdb/paths.pdb: include "libgimpmath/gimpmath.h"
where needed.
* app/pdb/paths_cmds.c: regenerated.
svn path=/trunk/; revision=22084

* app/config/*.c
* app/core/*.c
* app/display/*.c
* app/text/*.c
* app/vectors/*.c: port to G_DEFINE_TYPE() and friends. Some related
core reordering and cleanup.
2005-11-13 Sven Neumann <sven@gimp.org>
* app/core/gimpdatafactory.c (gimp_data_factory_data_free): do not
return a value from a void function. Fixes bug #321333.
2005-10-31 Sven Neumann <sven@gimp.org>
* app/core/gimpdata.[ch]
* app/core/gimpdatafactory.c: applied a heavily modified version
of the patch provided by Shlomi Fish in bug #311740. Introduces a
cache to speed up reloading of data files.
* app/actions/data-commands.c: set gimp busy while refreshing data
factories.
* app/widgets/gimpwidgets-utils.c (gimp_widget_accel_changed):
free the return value of gimp_get_accel_string().
2005-06-08 Sven Neumann <sven@gimp.org>
Removed "stingy-memory-use" all over the place. This feature was
really not that useful anymore. The GUI for the preference option
was already removed for GIMP 2.2. Fixes bug #306617.
* app/config/gimpbaseconfig.[ch]: set IGNORE flag on
"stingy-memory-use".
* app/config/gimpcoreconfig.h: added a comment that the
font_path_writable variable is unused.
* app/base/temp-buf.[ch]: removed code that used to deal with
swapping temp-bufs to disk.
* app/base/base.c: made base_config a static variable.
* app/core/gimpdata.[ch]
* app/core/gimpdatafactory.[ch]: removed stingy_memory_use
parameter from data construction methods.
* app/core/gimp-gradients.c
* app/core/gimpbrush-load.[ch]
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.[ch]

* app/core/gimpgradient.[ch]
* app/core/gimppalette-import.c
* app/core/gimppalette.[ch]
* app/core/gimppattern.[ch]: changed accordingly.
2005-04-13 Sven Neumann <sven@gimp.org>
* app/app_procs.c: register handler for the "GimpPaint" log domain.
* app/core/gimpdatafactory.c (gimp_data_factory_init): don't load
any data if TRUE is passed for no_data.
* app/tools/gimppainttool.c (gimp_paint_tool_draw): handle a NULL
brush gracefully.
2004-10-04 Michael Natterer <mitch@gimp.org>
* tools/pdbgen/pdb/brush.pdb
* tools/pdbgen/pdb/gradient.pdb
* tools/pdbgen/pdb/palette.pdb: disallow the empty string for
new brushes, gradients and palettes and check the return value
of gimp_data_factory_data_new(). Cleanup.
* app/core/gimpbrushgenerated.c (gimp_brush_generated_new)
* app/core/gimpgradient.c (gimp_gradient_new)
* app/core/gimpdatafactory.c (gimp_data_factory_data_new): same
here. Fixes bug #154264.
* app/core/gimpdata.[ch] (gimp_data_set_filename): added boolean
"deletable" parameter because it's not derivable from "writable".
* app/core/gimpdatafactory.c (gimp_data_factory_load_data): need
to figure "deletable" separately from "writable" to be able to
delete unsavable stuff in the user-writable data directories.
Fixes bug #154410.
(gimp_data_factory_data_save_single): cleaned up.
* app/pdb/brush_cmds.c
* app/pdb/gradient_cmds.c
* app/pdb/palette_cmds.c
* libgimp/gimpbrush_pdb.c
* libgimp/gimpgradient_pdb.c
* libgimp/gimppalette_pdb.c: regenerated.
2004-07-26 Michael Natterer <mitch@gimp.org>
* app/core/gimpdatafactory.h: added "gboolean writable" to the
GimpDataFactoryLoaderEntry struct. Return a GList* instead of
GimpData* from GimpDataLoadFunc so it's possible to load more than
one data object from one file.
* app/core/gimpdatafactory.c (gimp_data_factory_load_data):
changed accordingly: add all items of the returned lists to the
data factory. Make the data object writable only if it's in the
writable path *and* its loader entry says it's a writable format
*and* the returned list contains exactly one element.
* app/core/gimp.c (gimp_real_initialize): declare all loader
entries as writable where we have code to read and write exactly
one object per file; all others are not writable.
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.[ch]
* app/core/gimpbrushpipe.[ch]
* app/core/gimpgradient-load.[ch]
* app/core/gimppalette.[ch]
* app/core/gimppattern.[ch] (all load functions): return a list
containing the loaded object instead of the object itself.
2004-07-23 Sven Neumann <sven@gimp.org>
* app/core/gimpdatafactory.c: some newlines to improve error
messages.
* app/core/gimpgradient-load.c (gimp_gradient_load_svg): fixed
error handling.
2004-07-05 Sven Neumann <sven@gimp.org>
* app/core/gimpdata.[ch] (gimp_data_create_filename): Removed the
basename parameter and use the object name instead. Convert it to
the filesystem encoding.
* app/core/gimpdatafactory.c: changed accordingly.
2004-06-03 Sven Neumann <sven@gimp.org>
* app/core/gimpdatafactory.c (gimp_data_factory_load_data):
removed commented-out message.
* app/core/gimppattern.[ch]: fixed handling of errors and PNG
comments in new pattern loader. Renamed functions for consistency
with other data loaders.
* app/core/gimp.c: changed accordingly.
2004-06-03 Dave Neary <bolsh@gimp.org>
* app/core/gimp.c:
* app/core/gimpdatafactory.c:
* app/core/gimppattern.[ch]: Add support for GdkPixbuf patterns,
so now all of png, jpex, pnm, xbm, bmp, gif, ico, pcx, ras, tga,
xpm and tiff can be used for patterns.
2004-06-01 Michael Natterer <mitch@gimp.org>
* app/core/gimpdatafactory.[ch]: added new function
gimp_data_factory_data_delete().
* app/actions/data-commands.c (data_delete_callback): use it.
* tools/pdbgen/pdb/gradients.pdb: applied (slightly modified)
patch from Shlomi Fish which adds PDB wrappers to create, delete,
duplicate and rename gradients.
* app/pdb/gradients_cmds.c
* app/pdb/internal_procs.c
* libgimp/gimpgradients_pdb.[ch]: regenerated.
2004-05-24 Michael Natterer <mitch@gimp.org>
Long overdue core container cleanup:
* app/core/gimplist.[ch]: added "unique-names" and "sort-func"
properties and merged the resp. code from GimpDataList into
GimpList. Removed "policy" parameters from gimp_list_new() and
added "unique_names". Added new constructor gimp_list_new_weak().
Made public function gimp_list_uniquefy_name() private.
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpdatalist.[ch]: removed. Its functionality is
entirely in GimpList now.
* app/core/gimpdata.[ch]: added gimp_data_name_compare() which
used to live in GimpDataList.
* app/core/gimp.c
* app/core/gimpdatafactory.c
* app/core/gimpimage.c
* app/core/gimptoolinfo.c
* app/core/gimpundostack.c
* app/paint/gimp-paint.c
* app/tools/gimp-tools.c
* app/widgets/gimpdevices.c
* app/widgets/gimptemplateeditor.c
* app/widgets/gimpundoeditor.c: changed list creation accordingly.
Made gimp->templates, gimp->named_buffers, tool_info->presets and
the image's lists of layers, channels and vectors automatically
ensure unique names.
* app/widgets/gimptemplateview.c
* app/actions/file-commands.c
* app/actions/templates-commands.c
* app/actions/tool-options-commands.c: removed calls to
gimp_list_uniquefy_name().
* app/core/gimpitem.c: removed major insanity where the items
themselves where ensuring their unique names. Bah!
* app/core/gimplayer.c (gimp_layer_name_changed): chain up
conditionally.
* app/core/gimplayermask.c (gimp_layer_mask_name_changed): removed
because there is no need any more to keep the parent
implementation from being invoked.
2004-02-13 Michael Natterer <mitch@gimp.org>
Fixed GimpData's default "writable" and "deletable" behaviour:
* app/core/gimpdata.c (gimp_data_init): default to writable and
deletable == TRUE (something that has no filename was never loaded
from disk and can't be undeletable or read-only).
Fixes bug #134274.
* app/core/gimpdata.[ch]: added new function
gimp_data_make_internal() which frees the filename and sets the
data's flags accordingly.
* app/core/gimp-gradients.c (gimp_gradients_add_gradient)
* app/core/gimpbrush.c (gimp_brush_get_standard)
* app/core/gimpgradient.c (gimp_gradient_get_standard)
* app/core/gimppalette.c (gimp_palette_get_standard)
* app/core/gimppattern.c (gimp_pattern_get_standard): use the
new function for internal data objects.
* app/core/gimpdata.c (gimp_data_save, gimp_data_delete_from_disk)
* app/core/gimpdatafactory.c (gimp_data_factory_save_single):
bail out with g_return_if_fail() is the data is not writable
or deletable.
* app/widgets/gimpdataeditor.c
* app/widgets/gimpdatafactoryview.c: changed accordingly.
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.
2004-01-23 Michael Natterer <mitch@gimp.org>
* app/app_procs.c
* app/errors.c
* app/main.c
* app/config/gimpconfigwriter.c
* app/core/gimpdata.c
* app/core/gimpdatafactory.c
* app/gui/user-install-dialog.c
* app/plug-in/plug-ins.c
* app/vectors/gimpvectors-import.c: some more gimp_filename_to_utf8().
* libgimp/gimp.c
* libgimpmodule/gimpmodule.c
* libgimpmodule/gimpmoduledb.c: use it here, too, now that is in
libgimpbase.
2003-12-08 Michael Natterer <mitch@gimp.org>
* app/core/gimpdatafactory.c: code review / cleanup.
* app/plug-in/plug-in.c
* app/plug-in/plug-in-message.c: unified messages about plug-in
errors. Changed lots of g_warning()s to g_message()s because
g_warning() is for programming errors and the user should be
informed that the plug-in was killed and did not simply crash.
2003-08-25 Michael Natterer <mitch@gimp.org>
* app/core/gimpobject.[ch]: changed GimpObject::get_memsize() to
return a second value named "gui_size", where the primary return
value is the "constant" actual size (as long as no operation is
performed on the object), and the second "gui_size" return value
is the size of temporary stuff like preview caches or boundary
segments (which may change asynchronously, even if the object is
on the undo stack).
* app/core/gimp.c
* app/core/gimpbrush.c
* app/core/gimpbrushpipe.c
* app/core/gimpbuffer.c
* app/core/gimpchannel.c
* app/core/gimpcontainer.c

* app/core/gimpundostack.c
* app/core/gimpviewable.c
* app/text/gimptextlayer.c
* app/vectors/gimpstroke.c
* app/vectors/gimpvectors.c: changed get_memsize() implementations
accordingly.
* app/display/gimpdisplayshell-title.c
* app/gui/debug-commands.c
* app/widgets/gimppreview.c: changed callers accordingly.
* app/core/gimpimage-undo-push.c: changed layer, channel, vectors
and layer_mask undo steps to add/subtract the size of the
resp. objects whenever they take/drop ownership of them. Ignore
the objects' "gui_size" to get identical sizes on
adding/subtracting. Fixes bug #120429.
2003-07-02 Michael Natterer <mitch@gimp.org>
* libgimpbase/gimpbasetypes.h: changed GimpDatafileLoaderFunc to
take a separate "gpointer user_data" parameter (passing user_data
in a struct was a quite nonstandard API design). Made the
GimpDatafileData pointer const.
* libgimpbase/gimpdatafiles.[ch]: removed user_data from the
GimpDatafileData struct and added "const gchar *basename" so we
don't need to g_path_get_basename() in many callbacks.
* libgimp/gimpmiscui.[ch]: changed gimp_plug_in_parse_path() to
gimp_plug_in_get_path() and return the unparsed path.
* app/core/gimpdatafactory.c
* app/core/gimpenvirontable.c
* app/gui/gui.c
* app/plug-in/plug-ins.c
* libgimpmodule/gimpmoduledb.c
* plug-ins/script-fu/script-fu-scripts.c: changed accordingly.
* plug-ins/FractalExplorer/Dialogs.c
* plug-ins/FractalExplorer/FractalExplorer.[ch]
* plug-ins/FractalExplorer/Globals.c
* plug-ins/gfig/gfig.c
* plug-ins/gflare/gflare.c: use gimp_datafiles_read_directories()
instead of fiddling with g_dir_open() manually. Random cleanups.
2003-03-25 Sven Neumann <sven@gimp.org>
* Makefile.am
* gimpintl.h: removed this header file.
* gimpmiscui.c: include libgimp-intl.h.
* gimp.c (gimp_main): call setlocale() and bind to the libgimp
textdomain so that plug-ins don't need to do that explicitely.
* libgimp/stdplugins-intl.h: added the functionality that used to
live in gimpintl.h and removed the libgimp related stuff. Got rid
of the INIT_I18N_UI() macro.
* plug-ins/*/*.c: removed all occurances of INIT_I18N_UI().
Plug-ins simply call INIT_I18N() once in their run() function.
* plug-ins/script-fu/script-fu-intl.h: added the functionality
that used to live in gimpintl.h and removed the libgimp related
stuff.
* app/Makefile.am
* app/gimp-intl.h: new file that defines the gettext macros for
the GIMP core.
* app/*/*.c: include gimp-intl.h instead of libgimp/gimpintl.h.
* plug-ins/script-fu/scripts/test-sphere.scm: fixed typos.
2003-01-05 Manish Singh <yosh@gimp.org>
* many files in app, modules and libgimp*: cleanup, removed unecessary
G_OBJECT() casts. Should do the same for plug-ins, when more of them
get undeprecated.
2002-12-29 Sven Neumann <sven@gimp.org>
* configure.in
* etc/Makefile.am
* etc/gimprc.in
* etc/gimprc_user.in: removed templates for gimprc files.
* etc/gimprc: added this file as generated by gimp-config-dump.
* app/gui/user-install-dialog.c
* data/misc/user_install: don't install an empty user gimprc.
* app/config/Makefile.am
* app/config/gimpconfig-substitute.[ch]: removed these files.
* app/config/gimpconfig-path.[ch]: and added them again with
reduced functionality. Paths found in config files are now
basically handled like standard strings by the config system.
Users of the GimpConfig path variables need to expand the path
themselves.
* app/config/gimpbaseconfig.c
* app/config/gimpconfig-deserialize.c
* app/config/gimpconfig-dump.c
* app/config/gimpconfig-utils.c
* app/config/gimpconfig.c

* app/core/gimpmodules.c
* app/gui/user-install-dialog.c
* app/plug-in/plug-in.c
* app/tools/tools.c
* app/widgets/gimppropwidgets.c: changed accordingly.
2002-12-02 Michael Natterer <mitch@gimp.org>
* app/core/gimpdata.[ch]: use GError for reporting load/save
errors. Added gimp_data_error_quark() and a GimpDataError enum.
Made simple virtual functions out of save(), get_extension()
and duplicate() because they don't need to be signals.
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.[ch]
* app/core/gimpbrushpipe.[ch]
* app/core/gimpgradient.[ch]
* app/core/gimppalette.[ch]
* app/core/gimppattern.[ch]: changed accordingly. Set data->dirty
to FALSE in each _load() function.
* app/core/gimpdatafactory.[ch]: report GError messages here.
Changed the ugly factory->path pointer location hack to
factory->path_property_name and get the path from
factory->gimp->config. Added gimp_data_factory_data_duplicate()
implementation which was already declared in the header.
* app/core/gimp.c: pass the path property name to
gimp_data_factory_new().
* app/widgets/gimpdatafactoryview.c: removed the duplicate
implementation and call gimp_data_factory_data_duplicate().
* app/core/gimpgradient.[ch]: added gimp_gradient_save_as_pov().
* app/gui/gradients-commands.c: removed save_as_pov implementation
and call gimp_gradient_save_as_pov().
2002-11-30 Michael Natterer <mitch@gimp.org>
* app/base/base-types.h: removed the global "base_config" variable.
* app/base/base.[ch]: added "gboolean use_mmx" to base_init().
Don't #include "appenv.h". Pass around more parameters to reduce
the usage of the global "paint_options" pointer.
* app/app_procs.c: pass "use_mmx" to base_init().
* app/base/temp-buf.c: pass "temp_path" around internally. Declare
"base_config" extern and added a #warning.
* app/core/gimpdata.[ch]
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.[ch]
* app/core/gimpbrushpipe.[ch]
* app/core/gimpgradient.[ch]
* app/core/gimppalette.[ch]
* app/core/gimppattern.[ch]: added "gboolean stingy_memory_use"
parameters to all _new(), _load() and _duplicate() functions.
* app/core/gimpmarshal.list: GimpData::duplicate needs an
OBJECT__BOOLEAN marshaller now.
* app/core/gimpdatafactory.[ch]: added a "Gimp" pointer so the
factory can find the config. Pass base_config->stingy_memory_use
to the GimpData functions changed above.
* app/core/gimp-gradients.c
* app/core/gimp.c
* app/core/gimppalette-import.c
* app/gui/palettes-commands.c
* app/widgets/gimpdatafactoryview.c: changed accordingly.
* app/core/gimpcontext.c: get "stingy_memory_use" from
context->gimp->config.
2002-06-12 Michael Natterer <mitch@gimp.org>
* app/core/gimpdata.[ch]: added a boolean "internal" which
indicates that the data object is an automatically created
internal object. Changed the code to refuse saving to deleting
internal objects.
* app/core/Makefile.am
* app/core/gimp-gradients.[ch]: new files implementing internal
gradients (FG -> BG in RGB and HSV and FG -> transparent).
* app/core/gimp.c: call gimp_gradients_init().
* app/core/gimpdatafactory.c (gimp_data_factory_data_free): don't
free internal objects so they stay there on "Refresh".
* app/core/gimpdatalist.c: sort internal objects to the beginning
of the list.
* app/widgets/gimpdataeditor.c: refuse to change the name of
internal objects.
* app/widgets/gimpdatafactoryview.c: set the "Delete" button
insensitive for internal objects.
* app/widgets/gimpgradienteditor.c: refuse to edit internal
gradients, just display them so color picking works.
* app/gui/brushes-commands.c
* app/gui/gradients-commands.c
* app/gui/palettes-commands.c
* app/gui/patterns-commands.c: set the "Delete" menu item
insensitive for internal objects.
* app/gui/gui.c: need to call render_setup() earlier because of
you-dont-want-to-know-why. Will change it back once the previews
have their own render buffers.
* app/tools/gimpblendtool.c: Replaced the "Type" menu by a preview
showing the active gradient. Clicking the preview pops up the
gradient selection. Renamed the "Gradient" menu to "Shape". Removed
"blend_mode" from the BlendOptions struct because we always use
"custom" mode now.
