In GimpLineArt, use the "invalidate-preview" signal of the input
viewable, instead of its "painted" or "rendered" signals, for
asynchronously computing the line art. Subsequently, remove the
aforementioned signals from GimpDrawable and GimpProjection,
respectively. This simplifies the code, and reduces the number of
signals.
(cherry picked from commit ef9b1f6694)
This commit completely removes the "Edit -> Fade..." feature,
because...
- The main reason is that "fade" requires us to keep two buffers,
instead of one, for each fadeable undo step, doubling (or worse,
since the extra buffer might have higher precision than the
drawable) the space consumed by these steps. This has notable
impact when editing large images. This overhead is incurred even
when not actually using "fade", and since it seems to be very
rarely used, this is too wasteful.
- "Fade" is broken in 2.10: when comitting a filter, we copy the
cached parts of the result into the apply buffer. However, the
result cache sits after the mode node, while the apply buffer
should contain the result of the filter *before* the mode node,
which can lead to wrong results in the general case.
- The same behavior can be trivially achieved "manually", by
duplicating the layer, editing the duplicate, and changing its
opacity/mode.
- If we really want this feature, now that most filters are GEGL
ops, it makes more sense to just add opacity/mode options to the
filter tool, instead of having this be a separate step.

... in GimpBucketFillOptions for the line art algorithm.
Inside GimpLineArt, there are still 2 properties, but we don't show them
anymore in the Bucket Fill tool options. One of the main reason is
probably that it's hard to differentiate their usage. One is to close
with curved lines, the other with straight segments. Yet we don't
actually have any control on one or the other. All one knows is that you
can have "holes" in your drawing of a given size and you want them
close-like for filling. Only reason I can see to have 2 types of closure
is whether you'd want to totally disable one type of closure (then you
set it to 0). But this is a very limited reason for making the options
less understandable overall, IMO.
So for the time being, let's show up only a single option which sets
both properties in GimpLineArt. As patdavid says "it makes sense as a
first pass".
Also rename the option to shorter/simpler "Maximum gap length". Thanks
to patdavid and pippin for helping on figuring out this better label!
Finally I am bumping the default for the gaps to 100px. The original
values were ok for the basic small images used in demos, but not for
real life image where it was always too short (even 100px may still be
too short actually, but much better than the 20 and 60px from before!).

Practically it means that the algorithm won't close line art anymore
with both settings at 0. This can nevertheless still be a very useful
tool when you have a drawing style with well-closed lines. In such a
case, you will still profit from the color flooding under the line art
part of the algorithm.
Moreover with such well-closed zones from start, you don't get the
over-segmentation anymore and the threaded processing will be faster
obviously.

Zlib is a "better" compression in the meaning that it is a more advanced
and complex algorithm than RLE. And in most cases, it should end up in
smaller file sizes. But as any algorithm, there may be cases when the
expectations are not met (worst cases or such). That's the nature of the
maths. Still we should not make the checkbox text over-complicated (it
is not the place to teach algorithmic), yet we can at least add a small
tooltip text.
(cherry picked from commit c3ac722995)
This was my initial choice, but the more I think about it, the less I am
sure this was the right choice. There was some common code (as I was
making a common composite bucket fill once the line art was generated),
but there is also a lot of different code and the functions were filled
of exception when we were doing a line art fill. Also though there is a
bit of color works (the way we decide whether a pixel is part of a
stroke or not, though currently this is basic grayscale threshold), this
is really not the same as other criterions. In particular this was made
obvious on the Select by Color tool where the line art criterion was
completely meaningless and would have had to be opted-out!
This commit split a bit the code. Instead of finding the line art in the
criterion list, I add a third choice to the "Fill whole selection"/"Fill
similar colors" radio. In turn I create a new GimpBucketFillArea type
with the 3 choices, and remove line art value from GimpSelectCriterion.
I am not fully happy yet of this code, as it creates a bit of duplicate
code, and I would appreciate to move some code away from gimpdrawable-*
and gimppickable-* files. This may happen later. I break the work in
pieces to not get too messy.
Also this removes access to the smart colorization from the API, but
that's probably ok as I prefer to not freeze options too early in the
process since API needs to be stable. Probably we should get a concept
of experimental API.

After discussing with Mitch, it turn out commit 717c183a3e was fixing
(or rather working around) actual issues of broken device/usb stack
issues on Linux, as expected.
Nevertheless on Windows, this broke in turn many tablets (see commit
ce24e16083). Therefore we do a very ugly #ifdef to bail from duplicate
devices on Windows whereas we continue on Linux. This fix and difference
of behavior is completely empirical, rather than based on actual good
logics, so that's quite annoying, but well… not much choice here.
Also note that since we had no report of breakage on other OSes (such as
macOS/BSD), at least that I know of, I let them with the Linux code
path.

The code was too much spread out, in core and tool code, and also it was
made too specific to fill. I'll want to reuse this code at least in the
fuzzy select tool. This will avoid code duplication, and also make this
new process more self-contained and simpler to review later (the
algorithm also has a lot of settings and it is much cleaner to have them
as properties rather than passing these as parameters through many
functions).
The refactoring may not be finished; that's at least a first step.

(cherry picked from commit f7a4ce1051)
In particular, it allows to easily color pick. This just makes sense as
the bucket fill is definitely what one could call a "color tool", and
being able to easily change color without having to constantly switch to
color picker tool nor open a color chooser dialog is a must.
The fill type option (FG/BG/Pattern) was already mapped to the common
toggle behavior key (Ctrl on Linux), which is commonly used for
switching to color picker on paint tools. So I decided to remap the fill
type switch to GDK_MOD1_MASK (Alt on Linux) to keep consistent with
other tools (at the price of a change for anyone used to this modifier,
though I doubt it was that much used).
I also made possible to combine the 2 modifiers (so you could pick the
foreground or background color with ctrl and ctrl-alt).
(cherry picked from commit 5d4281944f)
The smart colorization was leaving irritating single pixels in between
colorized regions, after growing and combining. So let's just flood
these. We don't flood bigger regions (and in particular don't use
gimp_gegl_apply_flood()) on purpose, because there may be small yet
actual regions inside regions which we'd want in other colors. 1-pixel
regions is the extreme case where chances that one wanted it filled are
just higher.
(cherry picked from commit 744d67939d)
The distance map has all the information we need already. Also we will
actually grow up to the max radius pixel (middle pixel of a stroke).
After discussing with Aryeom, we realized it was better to fill a stroke
fully (for cases of overflowing, I already added the "Maximum growing
size" property anyway).
(cherry picked from commit 6bec0bc82d)
When flooding the line art, we may overflood it in sample merge (which
would use color in the line art computation). And if having all colors
on the same layer, this would go over other colors (making the wrong
impression that the line art leaked).
This new option is mostly to keep some control over the mask growth.
Usually a few pixels is enough for most styles of drawing (though we
could technically allow for very wide strokes).
(cherry picked from commit eb042e6c87)
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!
(cherry picked from commit dd3d9ab3dd)
For this, I needed distmap of the closed version of the line art (after
splines and segments are created). This will result in invisible stroke
borders added when flooding in the end. These invisible borders will
have a thickness of 0.0, which means that flooding will stop at once
after these single pixels are filled, which makes it quick, and is
perfect since created splines and segments are 1-pixel thick anyway.
Only downside is having to run "gegl:distance-transform" a second time,
but this still stays fast.
(cherry picked from commit 5a4754f32b)
We don't really need to flow every line art pixel and this new
implementation is simpler (because we don't actually need over-featured
watershedding), and a lot lot faster, making the line art bucket fill
now very reactive.
For this, I am keeping the computed distance map, as well as local
thickness map around to be used when flooding the line art pixels
(basically I try to flood half the stroke thickness).
Note that there are still some issues with this new implementation as it
doesn't properly flood yet created (i.e. invisible) splines and
segments, and in particular the ones between 2 colored sections. I am
going to fix this next.
(cherry picked from commit 3467acf096)
Introduced in commit b4e12fbbbb:
gimp_pickable_contiguous_region_prepare_line_art_async() was running
gimp_pickable_flush(), which provokes the "rendered" signal on the
image projection when a change occured. As a result, it was calling
gimp_bucket_fill_compute_line_art() within itself and since
tool->priv->async was not set yet, none of the call were canceled. Hence
the same line art is computed twice, but one is leaked.
Make sure we block this signal handler as a solution.
(cherry picked from commit 36c885a6df)
This commit is based on GEGL master as I just made the auxiliary buffer
of gegl:watershed-transform optional for basic cases.
It doesn't necessarily makes the whole operation that much faster

priority map was quite unnecessary.
(cherry picked from commit 963eef8207)
... and use in bucket-fill tool
Add gimp_pickable_contiguous_region_prepare_line_art_async(), which
computes a line-art asynchronously, and use it in the bucket-fill
tool, instead of having the tool create the async op.
This allows the async to keep running even after the pickable dies,
since we only need the pickable's buffer, and not the pickable
itself. Previously, we reffed the pickable for the duration of the
async, but we could still segfault when unreffing it, if the
pickable was a drawable, and its parent image had already died.
Furthermore, let the async work on a copy of the pickable's buffer,
rather than the pickable's buffer directly. This avoids some race
conditions when the pickable is the image (i.e., when "sample
merged" is active), since then we're using image projection's
buffer, which is generally unsafe to use in different threads
concurrently.
Also, s/! has_alpha/has_alpha/ when looking for transparent pixels,
and quit early, at least during this stage, if the async in
canceled.
(cherry picked from commit b4e12fbbbb)
When computing line-art, don't ref the bucket-fill tool in the
async data, and rather cancel any ongoing async upon tool
destruction, so that the async callback doesn't attept to touch the
now-dead tool. This avoids segfaulting in the async callback when
switching to a different tool, while a line-art async operation is
active.
Additionally, always cancel any previous async operation in
gimp_bucket_fill_compute_line_art(), even if not starting a new
one.
(cherry picked from commit 663a6c7011)
In the line-art async function, pass ownership over the resulting
buffer to the async object, so that the buffer is properly freed in
case the async in canceled after line-art computation is complete,
but before the completion callback is called.
Also, clear the tool's async pointer in the completion callback, to
avoid leaking the last issued async.
(cherry picked from commit 2e45c4c8c8)
The "update" signal on drawable or projection can actually be emitted
many times for a single painting event. Just add new signals ("painted"
on GimpDrawable and "rendered" on GimpProjection) which are emitted once
for a single update (from user point of view), at the end, after actual
rendering is done (i.e. after the various "update" signals).
Also better support the sample merge vs current drawable paths for
bucket fill.
(cherry picked from commit 047265333c)
Since commit b00037b850, erosion size is not used anymore, as this step
has been removed, and the end point detection now uses local thickness
of strokes instead.
(cherry picked from commit 3f58a38574)
Previous algorithm was relying on strokes of small radius to detect
points of interest. In order to work with various sizes of strokes, we
were computing an approximate median stroke thickness, then using this
median value to erode the binary line art.
Unfortunately this was not working that well for very fat strokes, and
also it was potentially opening holes in the line art. These holes were
usually filled back later during the spline and segment creations. Yet
it could not be totally assured, and we had some experience where color
filling would leak out of line art zones without any holes from the
start (which is the opposite of where this new feature is supposed to
go)!
This updated code computes instead some radius estimate for every border
point of strokes, and the detection of end points uses this information
of local thickness. Using local approximation is obviously much more
accurate than a single thickness approximation for the whole drawing,
while not making the processing slower (in particular since we got rid
of the quite expensive erosion step).
This fixes the aforementionned issues (i.e. work better with fat strokes
and do not create invisible holes in closed lines), and also is not
subject to the problem of mistakenly increasing median radius when you
color fill in sample merge mode (i.e. using also the color data in the
input)!
Also it is algorithmically less intensive, which is obviously very good.
This new version of the algorithm is a reimplementation in GIMP of new
code by Sébastien Fourey and David Tschumperlé, as a result of our many
discussions and tests with the previous algorithm.
Note that we had various tests, experiments and propositions to try and
improve these issues. Skeletonization was evoked, but would have been
most likely much slower. Simpler erosion based solely on local radius
was also a possibility but it may have created too much noise (skeleton
barbs), with high curvature, hence may have created too many new
artificial endpoints.
This new version also creates more endpoints though (and does not seem
to lose any previously detected endpoints), which may be a bit annoying
yet acceptable with the new bucket fill stroking interaction. In any
case, on simple examples, it seems to do the job quite well.
(cherry picked from commit b00037b850)
Other bucket fills are now done as filter until committed, but basic
selection fill is still done automatically. So let's make sure the
canvas is updated immediately (as it used to be before my changes).
(cherry picked from commit 287d90ba9e)
I have not added all the options for this new tool yet, but this sets
the base. I also added a bit of TODO for several places where we need to
make it settable, in particular the fuzzy select tool, but also simply
PDB calls (this will need to be a PDB context settings.
Maybe also I will want to make some LineArtOptions struct in order not
to have infinite list of parameters to functions. And at some point, it
may also be worth splitting a bit process with other type of
selection/fill (since they barely share any settings anyway).
Finally I take the opportunity to document a little more the parameters
to gimp_lineart_close(), which can still be improved later (I should
have documented these straight away when I re-implemented this all from
G'Mic code, as I am a bit fuzzy on some details now and will need to
re-understand code).
(cherry picked from commit 824af12438)
Rather than just having a click interaction, let's allow to "paint" with
the bucket fill. This is very useful for the new "line art" colorization
since it tends to over-segment the drawing. Therefore being able to
stroke through the canvas (rather than click, up, move, click, etc.)
makes the process much simpler. This is also faster since we don't have
to recompute the line art while a filling is in-progress.
Note that this new behavior is not only for the line art mode, but also
any other fill criterion, for which it can also be useful.
Last change of behavior as a side effect: it is possible to cancel the
tool changes the usual GIMP way (for instance by right clicking when
releasing the mouse button).

The older labelling based off CImg code was broken (probably because of
me, from my port). Anyway I realized what it was trying to do was too
generic, which is why we had to fix the result later (labeling all
non-stroke pixels as 0, etc.). Instead I just implemented a simpler
labelling and only look for stroke regions. It still over-label a bit
the painting but a lot less, and is much faster.

(cherry picked from commit 0c80f8a718)
When filling colors in line arts, you don't want to leave space between
the strokes and the color, which usually happen with any of the current
selection methods.
A "KISS" trick is usually to grow your selection a few pixels before
filling (adding an additional step in colorization process), which
obviously does not handle all cases (depending on drawing style and
stroke size, you may need to grow more or less) as it doesn't take into
account actual stroke geometry.
Instead, I label the selection and the "rest" differently and leave the
pixel strokes unlabelled. Then I let these unlabelled pixels be flooded
by the "gegl:watershed-transform" operation.
Note that this second step is different from the second step from the
GREYC research paper, as they use their own watershed algorithm taking
color spots as sources to color the whole image at once. This is a
different workflow from the one using bucket fill with a single color
source.
(cherry picked from commit 8502b4e743)
This commit implements part of the research paper "A Fast and Efficient
Semi-guided Algorithm for Flat Coloring Line-arts" from the GREYC (the
people from G'Mic). It is meant to select regions from drawn sketchs in
a "smart" way, in particular it tries to close non-perfectly closed
regions, which is a common headache for digital painters and colorists.
The implementation is not finished as it needs some watersheding as well
so that the selected area does not leave "holes" near stroke borders.
The research paper proposes a new watersheding algorithm, but I may not
have to implement it, as it is more focused on automatic colorization
with prepared spots (instead of bucket fill-type interaction).
This will be used in particular with the fuzzy select and bucket fill
tools.
Note that this first version is a bit slow once we get to big images,
but I hope to be able to optimize this.
Also no options from the algorithm are made available in the GUI yet.

We had many reports of tablets from various brands (Huion, Gaomon,
XP-Pen…) broken in the last release (though working fine when
downgrading to 2.10.6). Latest Huion drivers seem to fix the issue
(according to at least one report), but this is not the case for other
tablets.
Though unable to test myself, provided stderr logs indicate that we hit
the case when 2 devices with the same name are registered. Therefore
this commit is basically reverting commit 717c183a3e (though keeping and
completing the comments). I don't think there is an ultimate solution
here but with this regression, experience shows us there seem to be a
lot more breakage when overwriting the device with newer occurences (at
least on Windows). It is unclear though if commit 717c183a3e was also
supposed to fix another case actually encountered. If so, we will need
to get an even more advanced solution.

In GimpProjection's chunk renderer, when the chunk height changes
in the middle of a row, we need to merge the remainder of the
current render area back into the renderer's update region, and
refetch the remainder of the row as the new render area, so that we
don't miss any unrendered area, or re-render already-rendered area,
due to the change in chunk height. However, we should previously
fail to verify that the fetched area is, in fact, the remainder of
the current row, which could cause us to render the wrong area,
missing parts of the update region.
Fix this, by breaking up some of the chunk-renderer fucntions into
smaller sub-functions, and using those in order to explicitly set
the new render area to the remainder of the current row when the
chunk height changes. This also avoids erroneously merging the
unflushed update region of the projection into the renderer's
update region.

Actually, image grids are saved as parasites, so even though older
GIMP versions round their coordinates upon loading, they maintain
the fractional coordinates when re-saving the image, hence bumping

The NULL terminator of the tile-offset array of dummy buffer-levels

Since the dummy levels aren't actually used by GIMP, we're going to
keep these fields as int32 as an exception, in order to remain
consistent with existing XCFs, and just add a comment in the code,
and update the docs. If we ever make use of the higher buffer
levels, we should change these fields to offsets, and bump the XCF
version.
(cherry picked from commit 2168d91cf7)
Add a boolean "direct" parameter to gimp_projection_flush_now(),
which specifies if the projection buffer should only be invalidated
(FALSE), or rendered directly (TRUE).
Pass TRUE when flushing the projection during painting, so that the
affected regions are rendered in a single step, instead of tile-by-
tile. We previously only invalidated the projection buffer, but
since we synchronously flush the display right after that, the
invalidated regions would still get rendered, albeit less
efficiently.
Likewise, pass TRUE when benchmarking the projection through the
debug action, and avoid flushing the display, to more accurately
measure the render time.

Don't use a direct-buffer fill if the mode is subtractive, and the
composite region includes the source. Currently, this never
actually happens.
(cherry picked from commit 660f53d300)
In gimp_drawable_edit_fill(), when filling/clearing the whole
drawable, without any special compositing (i.e., when there's no
selection, the opacity is 100%, and the layer mode is trivial),
fill/clear the drawable's buffer directly, without using an
applicator. This makes such operations much faster, especially in
big images.
(cherry picked from commit dd8268c0a2)
... which is similar to gimp_fill_options_create_buffer(), however,
it fills an existing buffer, instead of creating a new buffer.
Implement gimp_fill_options_create_buffer() in terms of the new
function.
(cherry picked from commit 45fc4cb4f9)
Add a TRIVIAL layer-mode flag, and corresponding
gimp_layer_mode_is_trivial() function, which indicates if the blend
function of a given layer mode is trivial, i.e., either never
modifies the source pixels (for non-subtractive modes), or always
clears the destination pixels (for subtractive modes).
(cherry picked from commit 8adec5fb3a)
... which clears the alpha component of a given buffer region,
i.e., it makes the region transparent, while preserving color

In gimp_paint_core_finish(), when copying the relevant region of

(cherry picked from commit 861f356b63)
When creating a drawable undo from the drawable's buffer, align the
copied rectangle to the buffer's tile grid, so that all the copied
tiles are COWed, saving memory and gaining speed.
Add applied_x and applied_y fields to GimpDrawableUndo, specifying
the position at which to apply the applied_buffer, so that we apply
it in the right place, even if the undo rect has changed due to
alignment.

In the Luminance layer-mode, use the scratch allocator for
allocating temporary buffers, instead of using VLAs.
GimpOperationLayerMode already allocates data on the stack,
calculated as not to overflow the stack on any platform, so having
any of its descendants also allocate big buffers on the stack is
risky.
(cherry picked from commit 70b7316ebc)
Add a scratch-total variable to the dashboard's misc group, showing
the total amount of memory used by the scratch allocator.
(cherry picked from commit 698d1af798)
gimp-scratch is a fast memory allocator (on the order of magnitude
of alloca()), suitable for small (up to a few megabytes), short-
lived (usually, bound to the current stack-frame) allocations.
Unlike alloca(), gimp-scratch doesn't use the stack, and is
therefore safer, and will also serve bigger requests, by falling-
back to malloc().
The allocator itself is very simple: We keep a per-thread stack of
cached memory blocks (allocated using the normal allocator). When
serving an allocation request, we simply pop the top block off the
stack, and return it. If the block is too small, we replace it with
a big-enough block. When the block is freed, we push it back to
the top of the stack (note that even though each thread uses a
separate stack, blocks can be migrated between threads, i.e.,
allocated on one thread, and freed on another thread, although this
is not really an intended usage pattern.) The idea is that the
stacks will ultimately stabalize to contain blocks that can serve
all the encountered allocation patterns, without needing to reisze
any of the blocks; as a consequence, the amount of scratch memory
allocated at any given time should really be kept to a minimum.
(cherry picked from commit a8a8655285)
Use gimp_async_add_callback_for_object(), added in the previous
commit, instead of gimp_async_add_callback(), in cases where the
destructor of the object owning the async doesn't wait for the
async to finish. This avoids leaking such ongoing asyncs on
shutdown, during which gimp-parallel either finishes or aborts the
asyncs: if at this point an async has any registered callbacks, an
idle source is added for running the callbacks, extending the
lifetime of the async; however, since we're not getting back into
the main loop, the idle is never run, and the async (and any
associated resources) are never freed.
(cherry picked from commit 7c00cf498a)
... which is similar to gimp_async_add_callback(), taking an
additional GObject argument. The object is kept alive for the
duration of the callback, and the callback is automatically removed
when the object is destroyed (if it hasn't been already called).
This is analogous to g_signal_connect_object(), compared to
g_signal_connect().
(cherry picked from commit 49fd2847ac)
In gimp_async_remove_callback(), if removing the last callback
while the callback idle-source is already pending, cancel the idle
source and unref the async object (the async is reffed when adding
the idle source.)
(cherry picked from commit a779dd3849)
Use gimp_tile_handler_validate_validate(), added in the commit
before last, in gimp:buffer-source-validate, in order to pre-render
the necessary region of the buffer, instead of performing the
validation implicitly by iterating over the region. This is both
simpler, and, more importantly, allows us to render the entire
region in a single chunk, instead of tile-by-tile, which can be
considerably more efficient, especially with high thread counts.
This essentially extends the dynamic sizing of rendered projection
chunks to layer groups, which are rendered through
gimp:buffer-source-validate, rather than just the main image
projection.
(cherry picked from commit 83dd94ba6a)
Use gimp_tile_handler_validate_validate(), added in the last
commit, in GimpProjection, in order to render the projection,
instead of separately invalidating the buffer, undoing the
invalidation, and then rendering the graph. This is more
efficient, and more idiomatic.
(cherry picked from commit d6f0ca5531)
... which validates a given rectangle directly into the buffer,
possibly intersecting it with the dirty region. This is more
efficient than either invalidating, un-invalidating, and rendering
a given rect, as we're doing in GimpProjection, or validating the
buffer tile-by-tile, as we're doing in gimp:buffer-source-validate.
(cherry picked from commit 82a60997d4)
... which is similar to the ::validate() vfunc, however, it should
render the result to the provided GeglBuffer, instead of to a
memory buffer.
Provide a default implementation, which uses
gegl_node_blit_buffer() if the default ::validate() implementation
is used, or, otherwise, calls uses
gegl_buffer_linear_{open,close}(), and passes the returned memory
buffer to ::validate().
(cherry picked from commit 0ad41cfe0c)
Add begin_validate() and end_validate() virtual functions, and
corresponding free functions, to GimpTileHandlerValidate. These
functions are called before/after validation happens, and should
perform any necessary steps to prepare for validation. The default
implementation suspends validation on tile access, so that the
assigned buffer may be accessed without causing validation.
Implement the new functions in GimpTileHandlerProjectable, by
calling gimp_projectable_begin_render() and
gimp_projectable_end_render(), respectively, instead of calling
these functions in the ::validate() implementation (which, in turn,
allows us to use the default ::validate() implementation.)
In GimpProjection, use the new functions in place of
gimp_projectable_{begin,end}_render().

When an async that was created through

In gimp_drawable_transform_buffer_affine(), avoid modifying the
clipping mode when transforming layer masks, since this function is
used (among other things) to transform layer masks together with
their layer, in which case they should use the same clipping mode
as the layer.
This fixes a regression introduced by commit
2ae823ba2b, causing layer masks to be
transformed with a mismatched clipping mode during layer
transforms, leading to discrepencies between the transformed layer
and the transformed mask.
This commit merely reverts the necessary part of above commit,
fixing the regression, though note that this code is really up for
some serious refactoring: the logic for determining which clipping
mode to use when is spread all over the place.

Blacklist the "threaded-ml" thread, which seems to mask the

Furthermore, when one or more threads fail to handle the signal in
time, return a GimpBacktrace instance with backtraces for all the
other threads, and with empty backtraces for all the non-responding

Simplify gimp_view_renderer_drawable_render(), by consolidating
common code paths. In particular, when rendering the preview as
part of an image, always crop the preview to the bounds of the
image, even when downscaling, to avoid unnecessarily downscaling/
convering cropped-out regions. We previously only did this when
upscaling the preview by a factor of 2 or more; whatever the reason
for this used to be, it's no longer there.
(cherry picked from commit 8009ea342a)
In gimp_view_renderer_drawable_render(), avoid overflow in preview-

Use a single segment with a "step" blending function, added in the

On macOS, the "drag-end" signal does not seem to be emitted in some
cases, which leaves dockables in an unsensitive state. Rather than
trying to fix GTK+2 which is half-maintained nowadays anyway, let's drop
the unsensitivity. As a comment notes, this was anyway only a visual
cue. Dragging dockables in GIMP 2.10 already shows a lot of other visual
cues, so this is redundant.
In case of drop failure, we also had to cleanup the icon widget and
detach the dockable. This can be handled by the "drag-failed" (which
hopefully work better on macOS).
As an additional improvement, I raise the newly created dockable window,
since this is the most likely behavior when you just detached a dock
(and I realize it usually appeared behind other GIMP windows, at least
on GNOME).
Note: this is a gimp-2-10 only fix as master relies on GtkNotebook DnD
code which (hopefully, as I haven't tested) doesn't have this issue. The
detached window behind other windows issue doesn't exist on master, at
the very least.
In gimp_file_proc_view_get_proc(), when there is no selected

In the GUI implementation of gimp_wait(), explicitly finish the

In the gimp_parallel_run_async() family of functions, allow the
async callback to return without completing the async operation, in
which case the callback will be called again, until the operation
is either completed, or canceled, in which case it is aborted
(previously, returning from the callback without completing the
operation would cause it to be aborted.) It is guaranteed that all
operations of the same priority will get a chance to run, even if
some of them contuinuosly return without completing.
This allows potentially time-consuming operations to yield
execution in favor of other same-priority operations, and, in
particular, of higher-priority operations, to avoid priority
inversion. Essentially, this allows a simple form of cooperative
multitasking among async operations.

Replace GimpTransformTool's 'drawable' field with an 'item' field,
and have GimpTransformGridTool set it to the active item, to which
the transformation is applied, during its initialization. In
gimp_transform_tool_get_active_item(), return the value of the
transform tool's 'item' field, if not NULL, instead of the image's
active item. This makes sure we apply that transform-grid tools
apply the transformation for the item for which they were
activated, even if the image's active item has changed.

When shutting-down gimp-parallel, cancel and/or abort any ongoing
and queued async operations, instead of finishing them (async
operations that already started executing will be canceled, but
execution will be blocked until they're finished.) This is
especially important since we're shutting down gimp-parallel before
the destruction of data factories. This commit causes any ongoing
async operations of the factories to be canceled on shutdown,
rather than waiting for them to finish normally.
(cherry picked from commit e46fdc714e)
Add a new GimpData::data_cancel() virtual function, and a
corresponding gimp_data_factory_data_cancel() function. This
function should cancel any ongoing async operations related to the
factory (i.e., included in its async set), and wait for the
operations to finish. Provide a default implementation that simply
cancels and waits on the factory's async set.
Use this function to cancel any ongoing operations during factory
destruction, and in gimp_data_factory_data_free().
Override this function in GimpFontFactory, for which we can't
really cancel font loading, and simply cancel and clear the
factory's async set without waiting for loading to finish, making
sure that nothing happens (and, in particular, that the factory
isn't being accessed, since it might be already dead) when loading
does finish.

When re-activating an operation tool by clicking on a different
drawable while the tool is active, we re-call the corresponding

while the GUI still refers to the old, now-dead, config object,
causing CRITICALs or segfaults when changing any parameter.

this action to the active tool in tool-manager in response to a
matching dirty event, instead of unconditionally halting the tool.
Likewise, use this action to stop the active tool in response to a
button-press event on a different drawable in the same image.
Set the dirty action of the gradient and warp tools to COMMIT, so
that they get comitted, rather than stopped, in cases such as
switching layers (including switching to/from quick-mask mode),

Additionally, when erasing the last remaining segment (i.e., the

both points), but rather convert the segment to its initial point,

... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were

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.

to live with them for now.
In gimp_paint_core_loops_process(), initialize the iterator with
sufficient room for the number of iterators used by the algorithm
hierarchy, instead of a fixed number.
Add an additional 'rect' parameter to the init_step() and
process_rows() algorithm member functions, which receives the area
of the currently-processed chunk, to be used instead of the
iterator's ROI member. This allows us to pass a NULL iterator to
hierarchies that don't use an iterator, and avoid the stack-
allocated iterator hack we used in this case (and which became even
more problematic with the new iterator API).

My previous commit answers the forever question "do we want to require

the missing feature.
(cherry picked from commit 97247f41ea)
In addition to the verbose GIMP version, include in performance
logs the values of all environment variables beginning with BABL_,
GEGL_, or GIMP_, and of all the GEGL config options.
(cherry picked from commit 2c6b5c371e)
* The minimum GIMP version for this XCF is always written down when it
is GIMP 2.8 or over.
* The list of features warrating the minimum version is now listed in an
expander container rather than as tooltip (making the list actually
discoverable!).
* The warning on compression is now displayed as its own text under the
checkbox (only when checking the box actually changes anything
compatibility-wise), and not as additional text to the minimum GIMP
version label. Otherwise it had far too much weight on the minimum
compatible GIMP version text and people were wondering what it meant.
We should not tell people what the checkbox cannot do (it cannot
improve compatibility in some cases), only what it can do (it can
improve compatibility in other cases).
* Update the feature list real-time when checking the compression box
(making it even more obvious that tile compression may have a say in
compatibility).
* Metadata info is still added on the GIMP version label as it does not
limit compatibility of the XCF file itself.
(cherry picked from commit 573d817539)
Even though chosen as a parameter to gimp_image_get_xcf_version() and
not a feature within the image itself, we also want to list this reason
in the compatibility list.
(cherry picked from commit 0fa2ef9118)
When moving a text layer using the text tool (through alt+drag),
don't change the layer's box mode to "fixed", which is unnecessary,
since the layer's size isn't affected.
(cherry picked from commit 601c213c7a)
While editing a text layer with the text tool, update the layer's
frame when the layer moves, which most notably happens when
undoing/redoing a move operation while the text tool is active.
(cherry picked from commit 238c1035db)
The various functions of the text tool currently block and unblock
drawing (through gimp_text_tool_[un]block_drawing()) implicitly,
and in a non-symmetric fashion, which makes the tool's logic rather
fragile. Instead, require blocking/unblocking to be done
symmetrically, and explicitly block/unblock drawing as necessary in
all functions.

Improve out-of-range check in gimp_backtrace_find_thread_by_id().
Remove unnecessary #include <exchndl.h> in gimpbacktrace-windows.c,
and revert commit 644234e99d (the
DrMingw detection happens at runtime). The Windows backend can
work without DrMingw, it just can't find all the symbols, and
doesn't provide source-location information.
(cherry picked from commit b9f1ab8f53)
The "running" attribute (readable through
gimp_backtrace_is_thread_running(), and recorded in the performance
log) specifies if the thread was in a running or suspended state at
the time the backtrace was taken. It is accurate on Linux, but
only approximated on Windows.
Adapt the performance-log-expand.py tool to maintain this attribute
(and any future thread attributes we might add).
(cherry picked from commit 78adb7c900)
The Windows backend produces full, multithreaded backtraces. When
DrMingw is available, it also provides full symbol and (where
available) source-location information. Otherwise, it provides
symbol information for most of our libraries, but not for the GIMP
binary itself.
(cherry picked from commit 667efc221d)
Add source filename and line number fields to the
GimpBacktraceAddressInfo struct, populated through
gimp_backtrace_get_address_info(). This is not currently supported
by the Linux backend, but is supported by the Windows backend,
which we'll be added in the next commit.
(cherry picked from commit a6ec857123)
This function returns information about the given address, which
is currently mostly limited to the corresponding symbol
information, but we might want to add address-specific information
in the future, such as a line number.
(cherry picked from commit 7ac87dc01e)
In all the selection tools, show an error (and a BAD cursor
modifier) wheh starting a selection, if the current selection is
empty, and the tool is in SUBTRACT or INTERSECT mode (in which
case, the selection has no effect).
(cherry picked from commit 0e26525e65)
We're currently only using GimpHighlightableButton in the layers
dialog, which defines its own set of highlight colors. We're going
to use highlightable buttons in the dashboard too, so let's move
the highlight colors to gimphighlightablebutton.h, and give them
standard names. We currently define
GIMP_HIGHLIGHTABLE_BUTTON_COLOR_AFFIRMATIVE (green), and
GIMP_HIGHLIGHTABLE_BUTTON_COLOR_NEGATIVE (red).
(This commit was accidentally dropped from the gimp-2-10 branch; it
should have gone before 40ac4f7bc0f43aee24dc7ae1cf674d1a59612f55.)
Add an option to record a performance log through the dashboard.
The log contains a series of samples of the dashboard variables, as
well as the full program backtrace, when available. As such, it
essentially acts as a built-in profiler, which allows us to
correlate program execution with the information available through
the dashboard. It is meant to be used for creating logs to
accompany perofrmance-related bug reports, as well as for profiling
GIMP during development.
The sample frequency defaults to 10 samples per second, but can be
overridden using the GIMP_PERFORMANCE_LOG_SAMPLE_FREQUENCY
environment variable. Backtraces are included by default when
available, but can be suppressed using the
GIMP_PERFORMANCE_LOG_NO_BACKTRACE environment variable.
Logs are created through the new "record" button at the bottom of
the dashboard dialog. When pressed, a file dialog is opened to
select the log file, and, once confirmed, data is being recorded to
the selected file. Recording is stopped by pressing the "record"
button again (we use a highlight to indicate that recording is
active.)
While recording, the "reset" button is replaced with an "add marker"
button, which can be used to add event markers to the log. These
can be used to mark events of interest, such as "started painting"
and "stopped painting", which then appear in the log as part of the
sample stream. Markers are numbered sequentually, and the number
of the next (to-be-added) marker appears on the button. Shift-
clicking the button adds an empty (description-less) marker, which
is only identified by its number; this can be used when markers
need to be added quickly.
The log is an XML file, containing some extra information (such as
the output of "$ gimp -v", and symbol information) in addition to
the samples. The data in the file is delta-encoded to reduce the
file size, meaning that samples (as well as some other elements)
only specify the changes since the previous sample. This adds a
necessary decoding step before data can be processed; the next
commit adds a tool that does that.
There are currently no tools to actually analyze the data -- that's
still TBD -- but at least we can start gathering it.
GimpBacktrace provides an interface for creating and traversing
multi-threaded backtraces, as well as querying symbol information.
While we already have some backtrace functionality, it relies on
external tools for the most part, and as such is rather expensive,
and is only meant for producing opaque backtraces. GimpBacktrace,
on the other hand, is meant to be relatively cheap (we're going to
use it for profiling,) and allow inspection of the backtrace data.
In the future, it might make sense to replace some, or all, of the
other backtrace functions with GimpBacktrace.
GimpBacktrace currently only supports Linux. By default, it uses
dladdr() to query symbol information, which is somewhat limited (in
particular, it doesn't work for static functions.) When libunwind
is installed, GimpBacktrace uses it to get more complete symbol
information. libunwind is currently an optional dependency, but it
might make sense to promote it to a mandatory, or opt-out,
dependency, as it's lightweight and widely available.
On other platforms, the GimpBacktrace interface can still be used,
but it always returns NULL backtraces.
