Pass the current icon theme directory to plug-ins through the
config message, and add a gimp_icon_theme_dir() libgimp function
for retrieving it. Note that we already have a similar
gimp_icon_get_theme_dir() PDB function, which we keep around, since
it can be used to dynamically query for the current icon dir,
unlike the former, and since it returns a dynamically-allocated
string, while the rest of the config-related functions return
statically allocated strings.
Use the new function, instead of gimp_get_icon_theme_dir(), in
gimp_ui_init(). This allows gimp_ui_init() to run without making
any PDB calls. Consequently, this allows us to start plug-ins that
call gimp_ui_init() without entering the main loop in the main app.
We're going to add a plug-in that displays an interactive dialog
while the main app is blocking waiting for an operation to
complete, and we need to be able to start the plug-in without
entering the main loop, to avoid the possibility of arbitrary code
being executed during the wait.
Bump the protocol version.
While fonts are loading, show a GimpBusyBox with an appropriate
message above the text tool options, and make the options
themselves insensitive, and in font views, such as in the fonts
dialog (through gimp_container_editor_bind_to_async_set(), added in
the previous commit).
... which takes a GimpAsyncSet and a message, and shows a
GimpBusyBox with that message, instead of the container view, while
the async set is nonempty.
We're going to use this for font-loading indication in font views,
such as in the fonts dialog.
GimpBusyBox is used to show a message indicating an operation is in
progress. It's basically just a spinner and a label, with some
styling.
We're going to use it both in app/ and in a plug-in.
We already avoid rendering text layers while fonts are loading,
showing an appropriate message, but this will soon be replaced with
waiting for the fonts to finish loading.
Instead, don't allow the text tool to start at all while the fonts
are loading (showing an appropriate tool message, and a BAD cursor
modifier), and halt the tool when reloading fonts if it's already
started.
Replace the boolean fonts_loading member of Gimp with
fonts_async_set, which is a GimpAsyncSet object. This allows us
to easily respond to the completion of font loading and reloading,
as will be done in the next commits.
Additionally, move the call to FcConfigSetCurrent(), used to
activate the loaded font configuration, from the async thread to
the main thread, just to be on the safe side, and avoid calling
FcInitReinitialize() in gimp_fonts_reset() if font loading is still
in progress, which is unsafe.
GimpAsyncSet represents a dynamic set of running GimpAsync objects.
The objects are automatically removed from the set once they're
synced.
GimpAsyncSet implements the GimpWaitable and GimpCancelable
interfaces, allowing the entire set to be waited-on or canceled.
Additionally, GimpAsyncSet provides an "empty" property, which
indicates whether the set is empty or not. This allows responding
to the completion of all the GimpAsync objects through the set's
"notify::empty" signal, or drive UI changes through property
bindings.
GimpTriviallyCancelableWaitable is a proxy object for another
GimpWaitable object, implementing both the GimpWaitable interface
and the GimpCancelable interface. While waiting on the proxy
simply waits on the underlying waitable, canceling the proxy
doesn't affect the underlying waitable, even if it implements
the GimpCancelable interface as well, but rather causes subsequent
wait operations on the proxy to successfully complete immediately.
This essentially causes cancelation to abort only the wait, rather
than the underlying operation.
GimpUncancelableWaitable is a simple proxy object for another
GimpWaitable object, implementing only the GimpWaitable interface.
Its main purpose is to mask away the cancelability of an object
implementing both GimpWaitable and GimpCancelable.
In gimp_parallel_run_async(), lower the priority of threads
executing independent async operations. Independent operations
are generally potentially long-standing background tasks, which we
don't want to bog down the rest of the program.
This is currently only implemented on Linux and Windows.
In gimp_session_info_apply_geometry(), use gtk_window_resize() instead
of gtk_window_set_default_size() which magically fixes things. Leave a
big comment there because set_default_size() should just work.
Reset the canvas size request from gimp_display_shell_constructed() in
gimp_display_shell_canvas_size_allocate() so the image window can be
made smaller again. GTK+ 3.x always respects size requests.
- set GIMP3_DIRECTORY env variable not GIMP2_DIRECTORY
- make sure the cursors resource gets compiled in
- remove tab autosizing test, that code is gone
This is a first step to make our 2 symbolic themes into one and properly
"announce" them as symbolic through icon naming (which will allow
recoloring according to style colors).
With this CSS style, GTK+ widgets will search for symbolic icon variants
when using the generic name (with "*-symbolic" suffix).
We realize that gitlab doesn't encourage people to give base information
as software version or operating system.
Issue templates are not perfect but better than nothing.
...Generate .h files instead.
Generate proper .c and .h files for color-picker and tool cursors in
the directories where they are built, and stop including them in other
.c files.
The GIMP version string and the backtrace both look completely wrong
when pasted as-is on gitlab. Somehow all linefeed are gone.
This can be fixed by surrounding these as blocks (triple backticks),
using markdown syntax. Of course now the debug content is not for our
tracker only since packagers are encouraged to replace with their own
tracker URL, but this small markdown syntax is simple enough that it
should not break formatting on other platforms (as far as I know).
In gimp_parallel_run_async(), when aborting a GimpAsync operation
in reponse to its "cancel" signal, properly clean up internal data
attached to the object, to avoid use-after-free if the signal is
emitted again.
Add a boolean "independent" parameter to gimp_parallel_run_async().
When FALSE, the passed function is run in the shared async thread
pool; when TRUE, the passed function is run in an independent
thread.
Generally, async operations should run in the async pool, however,
it might be desirable to run long-standing operations, especially
ones that can't be canceled, in independent threads. This avoids
stalling quicker operations, and shutdown.
Adapt the rest of the code for the change. In particular,
initialize the font cache in an independent thread.
In gimp_parallel_run_async(), connect to the returned GimpAsync's
"cancel" signal, and abort the operation in response if it's still
enqueued, i.e., if its execution hasn't started yet.
Have GimpAsync implement the GimpWaitable and GimpCancelable
interfaces, added in the previous two commits, instead of providing
its own public version of the corresponding functions.
Add gimp_async_cancel_and_wait() as a convenience function for both
canceling an async operation, and waiting for it to complete.
Adapt the rest of the code to the change.
The code was basically leaking memory everywhere, and apparently on
purpose (according to a top comment). Even on short-lived process, not
properly managing memory is not a good habit, especially if we plan to
maintain a program for the long run.
So here are some fixes. I'm sure I must have missed some places (code
was a mess), and hopefully I broke nothing. But that's good for now. At
least it is somewhat sane code now.
Since commit 58fa382001, gimptool would accept source files with
non-standard extensions when using known C or C++ compilers. This would
include source with no extensions at all.
When this happens, do not try to set a pointer to a non-existing dot
separator to '\0'. That obviously segfaults.
Unlike the last two commits, we don't port GimpConfig to
G_DEFINE_INTERFACE(), since we need to provide a base initializer
for it. However, this commit aligns it with the rest of our
intefaces, by renaming gimp_config_interface_get_type() to
gimp_config_get_type(), and by performing class initialization for
the interface in a separate function than base initialization.
Keep gimp_config_interface_get_type() around as a deprecated
function, to maintain ABI compatibility. It will be removed in a
separate commit in master, so that this commit can be easily
cherry-picked to gimp-2-10.
