This is the script I have been personally using for some time now to
build the devel and nightly flatpak on my server regularly through cron
files.
It is not the best script, arguably, and we can most likely do better.
But for now, it worked for me and is a first step toward maybe making
official nightly flatpak builds soon.
That was an obvious faux ami with French.
Status changed to "press Enter to refine", with the requirement of
staying not too long (this is a status message, not documentation), and
that also announces what will be the next step.
In gimp_histogram_editor_validate(), clear the update timeout, so
that if we validate the histogram before the timeout (in
particular, if editor->histogram itself is clear) we don't end up
unnecessarily re-validating it at the timeout.
... which provides a set of higher-level lock-free atomic
operations.
Currently, the only two operations are
gimp_atomic_slist_push_head() and gimp_atomic_slist_pop_head(),
which atomically push/pop the first element of a GSList.
Code cleanup.
Improve function descriptions.
Improve function precondition checks.
Make sure the main thread is properly synced with the async thread
before calling the completion callbacks in the idle function.
Guarantee that all callbacks are called in FIFO order, even
callbacks added during the execution of other callbacks.
It is not obvious that you have to hit Enter to validate the first step
of Foreground Selection tool, i.e. the rough free selection. Adding this
information in status message.
Since Enter would only work once the free selection is closed or that
you have at least 3 points (then Enter closes the selection for you), I
also add gimp_free_select_tool_get_n_points() so that we can know how
many points were created from the Foreground Select tool, and only
update the status message when relevant.
This was added in commits 447d9bbc56 and fb6328b9ad.
With it, the validation succeeds. Still I am actually not sure that is
proper appdata format. Also we have issues of metadata not shown for our
flatpak package, and I am wondering if this could be the issue.
So let's get rid of this hack.
Also temporarily commenting out the appdata unit test because it fails
without, because of a bug in appstream-util. This bug has been fixed
since, but there are no releases containing this fix yet.
See: https://github.com/hughsie/appstream-glib/issues/234
We'll reactivate the tests later.
... drive roots (e.g. C:\, D:\, ...))
This is a regression of glib 2.56 (not applying to 2.54 since it is new
code). It has been fixed recently in what will be 2.56.2 but is not
released yet, so we can't just bump the requirement.
Since it is a pretty bad bug though, let's add a test specifically for
these versions in the configure script so that nobody will package these
versions of glib. We can remove this test when we will bump the glib
requirement.
In GimpHistogramView, connect the view to the bg-histogram's
"notify" signal, and update the view in response. Previously, we
only updated the view in response to the main histogram's "notify"
signal.
The curves tool only uses the bg-histogram, and after the switch to
asynchronous histogram calculation, in commit
49382e53d5, it failed to update the
histogram view after the calculation was complete.
Current code was only taking into account cancelation, so we could end
with weird plug-in return:
> HEIF/HEIC plug-in returned SUCCESS but did not return an image
Instead properly set an error status, and echo back the error from the
plug-in or libheif.
In GimpCurvesTool, calculate the histogram of the target drawable
asynchronously, rather than synchronously, to avoid blocking the UI
while the histogram is calculated.
In GimpLevelsTool, calculate the histogram of the target drawable
asynchronously, rather than synchronously, to avoid blocking the UI
while the histogram is calculated.
In GimpThresholdTool, calculate the histogram of the target
drawable asynchronously, rather than synchronously, to avoid
blocking the UI while the histogram is calculated.
Additionally, fix the initial "low" threshold value for > 8bpc
images (127/255 => 0.5).
In GimpHistogramEditor, calculate the histogram of the active
drawable asynchronously, rather than synchronously, to avoid
blocking the UI (and the execution of PDB calls) while the
histogram is calculated. For large images, this can notably
improve responsiveness, as well as plug-in execution speed, while
the histogram dialog is mapped.
... which is similar to gimp_drawable_calculate_histogram(),
calculating the histogram asynchronously on a separate thread.
Note that when calculating the histogram of the drawable's source
node, the node is rendered synchronously on the main thread (if
necessary), and the histogram of the result is calculated
asynchronously on a separate thread.
... which runs a user-provided function asynchronously, returning a
corresponding GimpAsync object. This can be used to execute code
off the main thread, using the GimpAsync object to synchronize as
necessary.
Note that while the code allows for running multiple asynchronous
functions in parallel in a thread pool, we currently limit the pool
to a single thread, queueing overlapping async function, since we
have no use for parallel asynchronous functions at the moment.
GimpAsync represents an asynchronous task, running without blocking
the main thread. It provides functions that allow waiting for
completion, queueing completion callbacks, and requesting
calcelation. See the code for more details.
The interface and the implementation are intentionally limited for
the time being, to keep things simple, and are geared toward
asynchronous tasks executed on a separate thread (see the next
commit). The public interface is relatively general, however, and
we may extend the implementation to support other kinds of tasks at
some point, who knows...
To avoid an infinite loop, gimp_item_linked_is_locked() was temporarily
unlinking items before calling gimp_item_is_position_locked(). This
worked only based on gimp_item_real_is_position_locked() code which
called gimp_item_linked_is_locked() only when it was linked. It did not
take into account the fact that it was an abstract method which could
have other implementations. In particular the group layer implementation
would call in turn gimp_item_is_position_locked() on each child layer.
Basically temporarily unsetting the link was anyway a very ugly hack.
The point is simply that we are only interested by the value of the
`lock_position` flag for this item, without further "intelligence". For
this, use gimp_item_get_lock_position() instead.
Displays can be opened multiple times, which caused the device manager
to try to add their devices multiple times (which gets prevented with
warnings), and then remove the devices prematurely when the
multiple-opened display gets closed the first time (which is even
worse).
Add a simple hash that keeps track of how often displays are open, and
only add/remove their devices on first open and last close.
This actually happened with gtk-inspector on the gtk3-port branch, but
there is no reason this can't also happen in stable.
