2006-03-31 Michael Natterer <mitch@gimp.org>
* app/pdb/gimpprocedure.[ch] (struct ProcRecord): added new member
"gboolean static_proc" which indicates whether a ProcRecord struct
and its strings are static.
(gimp_procedure_dispose): new function which frees the procedure's
args and values, and its strings if it is not static.
* app/xcf/xcf.c
* tools/pdbgen/app.pl: set "static_proc" to TRUE for static procs.
* app/pdb/procedural_db.c (procedural_db_free): call
gimp_procedure_free() or gimp_procedure_dispose(), depending on
procedure->static_proc.
* app/pdb/procedural_db.h: removed #if 0'ed cruft.
* app/plug-in/plug-in-proc-def.[ch]: removed
plug_in_proc_def_get_proc().
* app/file/file-open.c
* app/file/file-save.c
* tools/pdbgen/pdb/fileops.pdb: access proc_def->procedure directly.
* app/pdb/*_cmds.c: regenerated.
2006-03-30 Michael Natterer <mitch@gimp.org>
* app/pdb/procedural_db.c (procedural_db_execute_proc): don't
memset(0) the array of return values if the procedure didn't
succeed. GValues don't like to be treated like that and I don't
understand what the memsetting is good for. It just looks like a
very bad hack.
* app/file/file-open.c: additionally, don't access return_vals[>0]
unless the procedure returned successfully.
* app/core/gimppdbprogress.c
* app/widgets/gimppdbdialog.c: procedural_db_run_proc() always
returns non-NULL, no need to check for it.
2006-03-30 Michael Natterer <mitch@gimp.org>
* app/pdb/procedural_db.[ch] (struct Argument): replace the value
union by a GValue.
(procedural_db_argument_init)
(procedural_db_compat_arg_init): new functions to initialize
an Argument. They call g_value_init() on the Argument's value.
(procedural_db_arguments)
(procedural_db_return_values): initialize the returned Argument
arrays so their GValues are ready to use. Allow to get the
(unsuccessful) return values of a NULL ProcRecord.
(procedural_db_destroy_args): g_value_unset() the values. Added a
"gboolean full_destroy" parameter. Its only effect is to destroy
PDB arrays, everything else is nicely memory managed by GValue.
(procedural_db_execute)
(procedural_db_run_proc): do GValue stuff. Added n_args and
n_return_vals parameters to execute().
(procedural_db_execute_proc): private function to execute a
procedure. Validates the passed in arguments using the registered
GParamSpecs before passing them to the resp. exec method.
* app/plug-in/plug-in-params.[ch] (plug_in_params_to_args): needs
an array of ProcArgs now in order to initialize the Arguments'
GValues correctly. Passing NULL ProcArgs uses
procedural_db_compat_arg_init(), so procedures (plug-ins)
returning more values than expected work.
(plug_in_args_to_params): do GValue stuff here too.
(plug_in_args_destroy): removed this function,
procedural_db_destroy_args() does the same now.
* app/plug-in/plug-in-message.c (plug_in_handle_proc_run):
simplified quite a bit because everything returns n_return_values
now. Call plug_in_params_to_args() only of the procedure was found.
(plug_in_handle_proc_return_priv): pass ProcRecs to
plug_in_params_to_args().
* app/batch.c

* app/widgets/gimphelp.c
* app/widgets/gimppdbdialog.c
* app/xcf/xcf.c
* tools/pdbgen/pdb/fileops.pdb: changed accordingly: don't
g_new/g_free Argument arrays, always use procedural_db_foo()
functions. Use GValue functions to get/set Arguments.
* tools/pdbgen/pdb.pl: added get_value_func and set_value_func to
all PDB types. Removed id_func, id_ret_func and check_func. Added
flags which indicated that a type is an ID. Removed unused utility
functions.
* tools/pdbgen/lib.pl: use the flag instead of looking at
functions and value types.
* tools/pdbgen/app.pl: use the get_value_func and set_value_func
to marshal inargs and outargs. Removed all checks performed on
inargs because that's done by GParamSpec validation now. Added the
missing bits to register excluded values with GimpParamSpecEnum.
* app/pdb/*_cmds.c: regenerated.
2006-03-27 Michael Natterer <mitch@gimp.org>
* app/file/file-open.c
* app/file/file-save.c
* app/plug-in/plug-ins.c: use procedural_db_run_proc() instead of
procedural_db_execute(). execute() should be avoided for anything
but PDB-internal calls.
2005-10-31 Michael Natterer <mitch@gimp.org>
Applied modified patch from Luis de Bethencourt Guimera which adds
a "Save document history" prefs option. Fixes bug #140001.
* app/config/gimprc-blurbs.h
* app/config/gimpcoreconfig.[ch]: added boolean property
"save-document-hitory".
* app/core/gimp.c
* app/file/file-open.c
* app/file/file-save.c: don't save the document history and don't
add files to the desktop-wide list of recently used files if the
option is FALSE.
* app/dialogs/preferences-dialog.c: added its toggle to the
"Environment" page.
2005-09-26 Sven Neumann <sven@gimp.org>
* app/core/gimpdata.c
* app/file/file-save.c
* app/file/file-open.c: use g_access() from gstdio.h.
* app/config/gimpconfig-file.c (gimp_config_file_copy)
* libgimpthumb/gimpthumbnail.c: use g_chmod() from gstdio.h.
* app/file/gimprecentlist.c
* libgimpconfig/gimpconfigwriter.c: use g_creat() from gstdio.h.
2004-11-18 Sven Neumann <sven@gimp.org>
* app/file/file-open.c (file_open_thumbnail): check the number of
return values. Only retrieve width and height if the thumbnail
load procedure does actually provide such this information.
* plug-ins/common/postscript.c: added a procedure to loads
thumbnails. For now it only renders the first page of the
document at low resolution. It should be extended to load an
embedded thumbnail if available.
* plug-ins/common/jpeg.c
* plug-ins/common/svg.c: no need to register a menu label for the
thumbnail loaders. Allocate the return_vals array large enough to
hold all return values.
2004-11-13 Sven Neumann <sven@gimp.org>
* app/core/gimpimagefile.[ch]
* app/file/file-open.c

to gimp_imagefile_save_thumbnail() so that it can be stored with
the thumbnail.
* tools/pdbgen/pdb/fileops.pdb
* app/pdb/fileops_cmds.c: changed accordingly.
2004-11-13 Sven Neumann <sven@gimp.org>
* app/plug-in/plug-in-proc-def.[ch]
* app/plug-in/plug-in-rc.c
* app/plug-in/plug-ins.[ch]: allow to associate a procedure for
thumbnail loading with any file load procedure.
* tools/pdbgen/pdb/fileops.pdb: export this functionality to the
PDB as gimp_register_thumbnail_loader().
* app/pdb/fileops_cmds.c
* app/pdb/internal_procs.c
* libgimp/gimpfileops_pdb.[ch]: regenerated.
* app/core/gimpimagefile.c
* app/file/file-open.[ch]: when creating a thumbnail for an image
file, use a thumbnail load procedure if available.
* plug-ins/common/svg.c: added "file_svg_load_thumb", a procedure
that allows to load a small preview of the SVG image.
2004-11-10 Sven Neumann <sven@gimp.org>
* app/file/file-open.c (file_open_layer): add the image to the
list of recently used documents. Fixes bug #157879.
2004-10-23 Sven Neumann <sven@gimp.org>
* libgimpthumb/gimpthumb-utils.[ch]
* libgimpthumb/gimpthumbnail.[ch]
* libgimpthumb/gimpthumb.def: added missing API, mainly for deleting
thumbnails.
* app/core/gimpimagefile.[ch]: when saving a thumbnail, delete a
failure thumbnail if one exists. Unless the thumbnail was created
explicitely, remove all other thumbnails for this image.
* app/actions/documents-commands.c: changed accordingly.
* app/file/file-open.c: only save a thumbnail if there isn't a
valid thumbnail already.
* app/widgets/gimpthumbbox.c: before attempting to create a new
thumbnail, check if there's an uptodate failure thumbnail.
2004-10-12 Sven Neumann <sven@gimp.org>
* app/file/file-open.c: minor cleanup.
* app/file/file-save.c (file_save_as): no need to fiddle with the
image name, the URI is taken from the imagefile anyway.
2004-09-28 Sven Neumann <sven@gimp.org>
* app/config/gimpxmlparser.[ch]: added new convenience function
gimp_xml_parser_parse_fd().
* app/file/Makefile.am
* app/file/gimprecentitem.[ch]
* app/file/gimprecentlist.[ch]: added an implementation of the
recent-files spec as found on freedesktop.org. This code is taken
from libegg and has been edited to fit the GIMP needs.
* app/file/file-open.c
* app/file/file-save.c: update the ~/.recently-used file. Fixes
bug #131206.
2004-08-10 Michael Natterer <mitch@gimp.org>
Redid the whole internal progress stuff: don't pass around
progress_callback and progress_data; instead, provide a
pointer to a GimpProgressInterface which can be implemented
by a variety of backends.

2004-06-28 Michael Natterer <mitch@gimp.org>
* app/file/file-open.[ch] (file_open_layer): new utility function
which opens an image, flattens it if needed and returns the only
layer, converted for a passed destination image.
* app/display/gimpdisplayshell-dnd.c
(gimp_display_shell_drop_files): use the new function.
2004-06-01 Sven Neumann <sven@gimp.org>
* tools/pdbgen/pdb/image.pdb
* app/pdb/image_cmds.c
* app/core/gimpimage.[ch]: reverted changes I did to the image
unit earlier. As in 2.0, it will continue to not accept pixels.
This makes the PDB API and the XCF format compatible again and
fixes bug #142961 (and to some extent bug #137704).
* app/core/Makefile.am
* app/core/gimpimage-unit.[ch]: removed these files. The
convenience accessors defined here aren't commonly used any
longer.
* app/display/gimpdisplay.[ch]

2004-05-14 Sven Neumann <sven@gimp.org>
* tools/pdbgen/pdb/fileops.pdb: added new PDB function
gimp_register_file_handler_mime() that allows to associate a MIME
type with a file procecdurre.
* app/pdb/fileops_cmds.c
* app/pdb/internal_procs.c
* libgimp/gimpfileops_pdb.[ch]: regenerated.
* app/plug-in/plug-in-proc.[ch]

action name (taken from shared-mime-info) and register to the <Load>
and <Save> menus using gimp_plugin_menu_register().
2004-03-22 Michael Natterer <mitch@gimp.org>
* app/file/file-open.c (file_open_with_proc_and_display): removed
the undo clearing/sanitizing code...
(file_open_image): ...and added it here so *all* newly opened
images start with a clean and sane undo state.
* app/gui/file-commands.c (file_revert_confirm_callback): removed
(incomplete) undo sanitizing here too.
2004-03-15 Simon Budig <simon@gimp.org>
* app/core/gimpimage.[ch]
* app/core/gimpimage-undo.c: renamed gimage->freeze_count
to gimage->undo_freeze_count (more explicit).
* app/file/file-open.c: Ensure that the undo system is enabled
after loading an image (to protect against broken loaders).
2004-03-14 Simon Budig <simon@gimp.org>
* app/core/gimpimage.[ch]
* app/core/gimpimage-undo.c: introduced a freeze counter, so
that undo_freeze(); undo_freeze(); undo_thaw(); no longer
results in an thawed undo stack.
Fixes Bug #124176.
This might reveal other places in the code where
gimp_image_undo_freeze/thaw or gimp_image_undo_disable/enable
were used in an inconsistent (not-paired) manner.
* app/file/file-open.c: e.g. here, where _enable was called on
the new image. The intention was to free a potential undo stack,
so now call gimp_image_undo_free() instead.
2004-02-26 Pedro Gimeno <pggimeno@wanadoo.es>
* app/file/file-open.c (file_open_image): Applied a fix by
Michael Natterer addressing a problem with the preview in the
open images list when loading a file.
2004-02-03 Michael Natterer <mitch@gimp.org>
* app/plug-in/plug-in-proc.[ch]: added new function
plug_in_proc_def_compare_menu_path() which is a GCompareDataFunc.
(uses g_utf8_collate() on the translated menu paths).
* app/plug-in/plug-ins.c (plug_ins_init): sort gimp->load_procs
and gimp->save_procs using the new compare function above.
Fixes bug #133180.
(plug_ins_locale_domain)
(plug_ins_help_domain): don't g_return_if_fail() on a NULL
prog_name but return the default locale and help domains
of the GIMP itself.
(plug_ins_proc_def_insert): removed obsolete and broken (not
locale and UTF-8 aware) code which tried to insert new plug-in
menu entries in alphabetical order (was unused except for load
and save procs).
Unrelated:
* app/plug-in/plug-in-proc.[ch]: added const qualifiers.
* app/file/file-open.c
* app/file/file-save.c
* tools/pdbgen/pdb/fileops.pdb: changed accordingly (constify
local variables).
* app/pdb/fileops_cmds.c: regenerated.
2004-01-29 Simon Budig <simon@gimp.org>
* app/display/gimpdisplayshell.[ch]: Store the zoom factor as
float, not as a ratio.
* app/display/gimpdisplayshell-scale.[ch]: change the API to
expose the Float instead a weirdly encoded integer. Implement
functions to get a ratio from the scale factor. Implement a set
as presets as discussed on the mailinglist. Changed Zoom->Other
dialog to enable entering a float.
* app/display/gimpdisplayshell-title.c
* app/display/gimpnavigationview.c
* app/gui/image-menu.c

2003-11-27 Michael Natterer <mitch@gimp.org>
* plug-ins/common/ps.c (create_new_image): don't add the page
number to the filename of the image corresponsing to the
postscript file's first page. Enables thumbnail generation
for PS files.
Indented function prototypes.
* app/file/file-open.c (file_open_with_proc_and_display): create a
thumbnail of the opened image only if the image's uri matches the
passed uri.
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.
2003-03-05 Michael Natterer <mitch@gimp.org>
* app/file/file-save.[ch]: added GError reporting, removed
g_message() stuff.
* app/gui/file-commands.c
* app/gui/file-save-dialog.c: g_message() here if file_save_*()
returns an error.
* app/file/file-open.c: use the G_FILE_ERROR quark and the
GFileError enum for reporting errors. Removed g_message() if the
passed in GError** pointer is NULL (passing NULL as error return
location should never mean "show the error message yourself").
* app/app_procs.c
* app/gui/file-commands.c
* app/gui/file-open-dialog.c
* app/widgets/gimpdnd.c
* app/widgets/gimpdocumentview.c: g_message() here if file_open_*()
returns an error.
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.
2002-05-15 Sven Neumann <sven@gimp.org>
* app/config/gimpconfig.[ch]: added a return value to indicate
success of GimpConfigInterface::serialize. Added a GimpConfigError
value for write errors and check the return value of all write()
calls. Allow to specify file header and footer when calling
gimp_config_serialize().
