This removes all usages of the non-standard put helper method and
replaces all of it's usages with the specification required alternative
or with define_direct_property where appropriate.
These are usually incorrect, and people sometimes forget to add the
correct values as a result of them being optional, so they should just
be specified explicitly.
This removes all usages of the non-standard define_property helper
method and replaces all it's usages with the specification required
alternative or with define_direct_property where appropriate.
Since the object rewrite native property getters/setters are always
called with the owning object as the this_value, which in this case is
an Array object, and as such this checks are always false.
The Number constructor previously didn't support converting BigInts to
regular numbers, so I used parseInt as a workaround.
Since it now supports this, this workaround is no longer needed.
It didn't really make sense for the transparency grid to extend
infinitely around the image. Now the grid is only visible underneath
the image, which matches how most other editors behave.
We now divide each scanline into prologue, aligned run, and epilogue.
Basically, we draw enough pixels one-by-one until we reach a grid
intersection. Then we draw full grid cell slices using fast memory
fills. Finally we go back to one-by-one for the epilogue.
This is roughly 2.5x faster in a microbenchmark and no longer dominates
the ImageViewer and PixelPaint resizing profiles.
We were creating a new memory mapping every time WindowServer performed
a buffer flip. This was very visible in whole-system profiles, as the
mapping and unmapping of MMIO registers caused quite a bit of kmalloc()
and kfree() churn.
Avoid this problem by simply keeping the MMIO registers mapped.
The call to enumerable_own_property_names in the non-array case was
missing an exception check.
Fixes 1 test262 case (JSON/parse/reviver-object-own-keys-err.js)
This requires variables that should be exported to the script host
or to other scripts to be declared as var (such as in test-common.js),
since lexically-scoped variables won't be visible.
This was an old SerenityOS-specific syscall for donating the remainder
of the calling thread's time-slice to another thread within the same
process.
Now that Threading::Lock uses a pthread_mutex_t internally, we no
longer need this syscall, which allows us to get rid of a surprising
amount of unnecessary scheduler logic. :^)
This class was previously a spinlock that would call sys$donate()
to donate its timeslice to whichever thread was holding the lock.
Now that pthread_mutex_t has a fast path, let's implement Lock on top
of that instead and get rid of the last remaining user of sys$donate().
This provides more crucial information to be able to do an addr2line
lookup on a backtrace captured with Thread::backtrace.
Also change the offset to hexadecimal as this is what is require for
addr2line.
- Fix evaluation order: IsArray(O) should always be called and before
Get(O, @@toStringTag), previously it was the other way around and
IsArray would only be called if @@toStringTag is not a string
- Add missing exception checks to both function calls
- Add missing builtin tag for arguments object
Also, while we're here:
- Update variable names to match spec
- Add spec step comments
Previously move_selection() did not work as expected. Instead store the
selected layer index in a member variable and continue to cycle through
the layers when you come to the start/end. Also use it to scroll into
view. Lastly rename the function to cycle_through_selection() to make it
clearer what it does.
This enables the layer menu as a context menu in LayerListWidget,
setting the clicked layer as active for now, but in the future it
would be nice to have custom menu applying to the clicked layer instead
of the active layer.
