clang doesn't make all `Base::visit_edges()` calls CXXMemberCallExprs
This would lead to false positives like in HeapFunction,
where the matcher would fail to match and report a warning.
Also previously the matcher would succeed
if the visited class is missing the call to `Base::visit_edges()`
but an included class has a correct method.
The new matcher checks the current class for `visit_edges`-overrides
and matches all `visit_edges`-memberExprs inside,
checking those for starting with `Base::`.
This seems to get rid of the false positives
and should be more correct detecting missing calls.
When building, clang would throw errors about dangling references.
Extracting `template_args` to a variable before the loop and
indexing into that seems to fix the errors.
This patch implements the File API spec's supplemental steps for
document's "unloading document cleanup steps" so that we now remove blob
URLs associated with the document's relevant settings object when the
document is being unloaded.
Fixes two realm leaks when running our test suite.
f66d33423b was not sufficient to ensure
document destruction when a child navigable is destroyed. This is
because a navigable was remove from the set of all navigables too early
which led to `Navigable::navigable_with_active_document()` being unable
to find a navigable that is still in the process of destruction.
This change solves that by making all steps of a navigable destruction
to happen in afterAllDestruction callback.
Unfortunately, writing a test to verify document destruction is
challenging because no events are emitted to indicate that it has
happened.
By default, Qt will grow the width of a tab button to fit the title text
of the tab. For long titles or file:// URLs, this looks rather bad. This
sets a min/max tab width to prevent such infinite growth.
To do this, we have to subclass both QTabWidget and QTabBar, because the
functions to be called/overridden are protected.
Switching away from SafeFunction immediately backfired here, as we're
dealing with two layers of captures, not one.
Let's do the correct fix, which is to use HeapFunction. This makes the
API and its behavior explicit, and keeps captures alive as long as the
HeapFunction is alive.
Fixes#23819.
This is one of the cases where SafeFunction actually makes sense.
Since every resource load will always either succeed, fail, or time out,
it's okay to use a SafeFunction since we know it will eventually get
destroyed.
Until it does, this allows it to keep any captures alive.
This needed the same `jbig2` changes as for the non-transposed ones,
and the changes to it mentioned on #23780.
I used the same .ini files as for the non-transposed ones, except
that I added `-txt -Param -Transposed 1` as last line to each of them.
All three new files display fine in Chrome.
They all look busted in Firefox.
I think this is likey a bug in pdf.js that I'll report upstream.
(Reportedly they look fine in Acrobat on Android.)
This already worked fine. Now it's tested.
I did have to teach `jbig2` to correctly generate test files for this.
See the PR adding these tests for local changes.
I used the script from #23659 to create these images, but I replaced
these lines:
```
-txt -Param -numInst 4
-ID 2 108 50 -ID 3 265 60 -ID 1 100 135 -ID 0 70 232
-txt -Param -RefCorner 2
```
For `bottomleft`, I replaced them with:
```
-txt -Param -numInst 4
-ID 2 137 50 -ID 3 294 60 -ID 1 199 135 -ID 0 319 232
-txt -Param -RefCorner 0
```
For `bottomright`, I replaced them with:
```
-txt -Param -numInst 4
-ID 2 108 50 -ID 3 265 60 -ID 1 100 135 -ID 0 70 232
-txt -Param -RefCorner 2
```
For `topright`, I replaced them with:
```
-txt -Param -numInst 4
-ID 2 108 79 -ID 3 265 89 -ID 1 100 234 -ID 0 70 351
-txt -Param -RefCorner 3
```
All three new files display fine in Chrome.
The bottomleft one displays fine in Firefox, while the other two
look compressed in X. I think this is a bug in pdf.js that I'll
report upstream.
(Reportedly they look fine in Acrobat on Android.)
SafeFunction was causing massive GC reference cycles here and leaking
entire realms as a result.
Since we end up storing these reaction steps in a JS::NativeFunction
(which uses JS::HeapFunction internally) there should be no need to
protect the captures with SafeFunction.
This dramatically shrinks our memory footprint while running tests.

Before this change it only worked because of another bug in
`EventLoop::spin_processing_tasks_with_source_until()`
where we execute tasks regardless of whether they are runnable or not.
