While this issue was unseen so far on common desktop machines, the CI
build encountered it, hence failing 6 of the unit tests.
A connection to the bus could not be established hence the dbus_manager
was never allocated, and finally it would crash at exit if we tried to
unref it unconditionnally. Use g_clear_object() instead.
Also add some stderr output for easier debugging, for when one of the 2
possible error cases might happen (as documented by g_bus_own_name()).
Tested in a VM. Minimized window is properly deiconified and showed to
the front. Though a window in the back (not minimized) is not moved to
the front.
GimpDisplay contains only the ID logic and the "gimp" and "config"
pointers, and lives in the core.
GimpDisplayImpl is a subclass and contains all the actual display
stuff. The subclass is only an implementation detail and doesn't
appear in any API.
Remove all hacks which pass displays as gpointer, GObject or
GimpObject through the core, or even lookup its type by name,
just use GimpDisplay.
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
GimpConfigWriter contains several constructors with the convention
`gimp_config_writer_new_* ()`. This will lead to problems however with
languages like Vala, where it cannot disambiguate the following:
```
// calls config_writer_new_string()
Gimp.ConfigWriter w = new ConfigWriter.string("xxx");
// calls config_writer_string()
w.string("xxx")
```
Using `from_` in constructors is general practice in GObject-bsed
libraries because of this.
This also fixes an error when trying to use vapigen on the GIMP .GIR
file.
which means that it's now included normally via gimpbase.h
and not any longer via gimpbasetypes.h which we only did out
of lazyness. A *lot* of files in libgimp* and app/ now need to
- libgimpbase: change GPParam to transfer all information about the
GValues we use, in the same way done for GPParamDef. GPParam is now
different from GimpParam from libgimp, pointers can't be casted any
longer. The protocol is now completely GimpPDBArgType-free. Remove
gp_params_destroy() from the public API.
- libgimp: add API to convert between an array of GPParams and
GimpValueArray, the latter is now the new official API for dealing
with procedure arguments and return values, GimpParam is cruft (the
wire now talks with GimpPlugIn more directly than with the members
of GimpPlugInInfo, which need additional compat conversions).
- libgimp, app: rename gimpgpparamspecs.[ch] to simply
gimpgpparams.[ch] which is also more accurate because they now
contain GValue functions too. The code that used to live in
app/plug-in/plug-in-params.h is now completely in libgimp.
- app: contains no protocol compat code any longer, the only place
that uses GimpPDBArgType is the PDB query procedure implementation,
which also needs to change.
- app: change some forgotten int32 run-modes to enums.
There are no replacements. Just we must make sure that all GTK+/GDK
calls are run from the main thread, which is already what we were doing.
Actually I don't even think these were doing anything as we were not
calling gdk_threads_init() so the default lock functions were not set
anyway. These were just bogus calls.
Step one: get rid of all those deprecation warnings that make
it hard to see any other warnings:
- add a lot of dummy API to GimpAction, GimpActionGroup, GimpUIManager
etc. which simply forwards to the deprecated GTK functions, they
will all go away again later
- rename GimpAction to GimpActionImpl
- add interface GimpAction that is implemented by all action classes,
creates a common interface and allows to remove some duplicated
logic from GimpToggleAction and GimpRadioAction, and at the same
time adds more features
Include the system-wide gimp.css file, in addition to the user-
specific gimp.css file, in the generated theme.css file, instead of
copying the former into the latter when creating the user's
gimpdir. This allows us to modify the system-wide gimp.css file,
and having the changes take effect in existing installations.
The GUI implementation of gimp_wait() relies on the ability to run
plug-ins (namely, the busy-dialog plug-in) without entering the
main loop. This prohibits the said plug-ins from making any PDB
calls, which would result in a deadlock. However, we're currently
calling gimp_gimprc_query() to fetch the prefer-dark-theme option
during gimp_ui_init() (or any time the theme.css file changes).
Instead, communicate this preference through the theme.css file
itself, by writing a /* prefer-dark-theme */ comment to the file
when the option is set. Yes, it's a bit of a hack :P
When an error occurs, we want to prevent overwriting any previous
version of the file by incomplete contents. So run
g_output_stream_close() with a cancelled GCancellable to do so.
See also discussion in #2565.
I had this funny behavior when I was quitting GIMP with the active tool
using modifiers (for instance bucket fill). Each time I'd quit with
ctrl-q (and if the image is not dirty), the options would use the value
from the modifier state and be saved as-is. Hence at next restart, the
default value was always different!
In the GUI implementation of gimp_wait(), explicitly finish the
input-pipe async operation after the busy-dialog plug-in
terminates, to avoid the async callback function from being
repeatedly called, stalling the main thread. Previously, this code
relied on gimp-parallel implicitly aborting the async operation,
but this is no longer the case since commit
4969d75785.
... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
A single icon theme can contain both regular and symbolic icons. Let's
give possibility to switch from one style to the other within GIMP
Preferences.
This won't work very well in all cases yet, especially if an icon theme
only has symbolic icons (and no regular ones) because of inconsistencies
in glib which are being fixed (patches which I submitted and which were
merged in glib on 2018-08-17).
So this will work as expected when we will bump our glib requirement to
whatever is the next release.
Not the most useful type of extensions per-se, but a lot of people seem
to appreciate creating and installing new splashes. Let's make it easy
to install as extensions.
Note that extension splashes are cumulative. So if you enabled several
splash extensions at once, an image would be chosen in random amongst
all of them.
Remove the "independent" parameter of gimp_parallel_run_async(),
and have the function always execute the passed callback in the
shared async thread-pool.
Add a new gimp_parallel_run_async_full() function, taking, in
addition to a callback and a data pointer:
- A priority value, controlling the priority of the callback in
the async thread-pool queue. 0 is the default priority (used
by gimp_parallel_run_async()), negative values have higher
priority, and positive values have lower priority.
- A destructor function for the data pointer. This function is
called to free the user data in case the async operation is
canceled before execution of the callback function begins, and
the operation is dropped from the queue and aborted without
executing the callback. Note that if the callback *is*
executed, the destructor is *not* used -- it's the callback's
responsibility to free/recycle the user data.
Add a separate gimp_parallel_run_async_independent() function,
taking the same parameters, and executing the passed callback in
an independent thread, rather than the thread pool. This function
doesn't take a priority value or a destructor (and there's no
corresponding "_full()" variant that does), since they're pointless
for independent threads.
Adapt the rest of the code to the changes.
Also remove all traces of it from the plug-in protocol and raise the
protocol version to 0x0100 (we now allow features and therefore
version bumps in stable, and the master protocol version should always
be higher). Fix the code that aborts plug-in startup on protocol
version mismatch, we can't use gimp_message() because we have no
protocol.
Add a GimpGui::wait() virtual function, and a corresponding
gimp_wait() function. The function takes an object implementing
the GimpWaitable interface, and a printf-style message, and waits
for the object to become ready, displaying the message as
indication in the meantime. The default implementation simply
prints the message to STDERR.
Implement the function in gui-vtable, using the busy-dialog plug-
in added in the previous commit, to display the message in a
dialog. Additionally, if the object implements the GimpCancelable
interface, provide a "cancel" button in the dialog, which, when
pressed, causes gimp_cancelable_cancel() to be called on the
object. Note that the function keeps waiting on the object even
after requesting cancelation; GimpTriviallyCancelableWaitable can
be used to stop the wait once cancelation has been requested.
