We'd unconditionally get the int from a Variant<int, float> here,
but PDFs often have a float for defaultWidthX and nominalWidthX.
Fixes crash opening Bakke2010a.pdf from pdffiles (but while the
file loads ok, it looks completely busted).
We already set these variables and call `_init` in the dynamic linker.
As we don't care about static binaries, remove these assignments and the
call to `_init` from `_entry`.
The function referenced by DT_INIT is also not necessarily called
`_init`, so directly calling `_init` is not really correct.
`s_global_initializers_ran` and `__stack_chk_guard` are unused, so
remove them.
We currently don't call any DT_FINI_ARRAY functions, so change that.
The call to `_fini` in `exit` is unnecessary, as we now call the
function referenced by DT_FINI in `__call_fini_functions`.
We currently store a StringView into the DeprecatedString provided to
SVGUseElement::attribute_changed. This is a temporary string created by
String::to_deprecated_string, so this StringView is always a dangling
pointer.
Instead, since this string value is an ID and is primarily used as a
FlyString, store it as a FlyString from the get-go.
This was the only remaining codec that produced IndexedN bitmaps.
By removing them, we'll be able to get rid of those formats and simplify
the Bitmap and Painter classes.
Instead of resolving lengths used in the backdrop-filter during
painting, we can do that earlier in apply_style().
This change moves us a bit closer to the point when the stacking
context tree will be completely separated from the layout tree :)
Previously, every time a page switched fonts, we'd completely
re-parse the font.
Now, we cache fonts in Renderer, effectively caching them per page.
It'd be nice to have an LRU cache across pages too, but that's a
bigger change, and this already helps a lot.
Font size is part of the cache key, which means we re-parse the same
font at different font sizes. That could be better too, but again,
it's a big help as-is already.
Takes rendering the 1310 pages of the PDF 1.7 reference with
Build/lagom/bin/pdf --debugging-stats \
~/Downloads/pdf_reference_1-7.pdf
from 71 s to 11s :^)
Going through pages especially in the index is noticeably snappier.
(On the PDF 2.0 spec, ISO_32000-2-2020_sponsored.pdf, it's less
dramatic: From 19s to 16s.)
This allows the decoder to fail gracefully when reading a partial or
malformed TBSCertificate. We also now ensure that the certificate data
is valid before making a copy of it.
493dd5d93c caused the `::before`
pseudo-element node to be inserted before the element's content, which
caused issues with how we determine where to insert inline nodes into
the layout tree. At the time, I noticed the issue with contents of flex
containers, and prevented them from merging into a `::before` box.
However, a similar situation happens when we're not in a flex container,
but the pseudo-element has `display: block`. This commit fixes that
situation by using the same logic in both places, so a similar mistake
can't be made again.
This fixes the tab text being invisible on GitHub project pages. :^)
Previously, `load_from_memory()` just took a raw pointer to the data,
and then manually calculated offsets from that pointer. Instead, let's
use the MappedFile we already have, to stream in the data, to make
things a bit safer. We also now check that the entire file's data was
read, since if there was data left over, then either the file is bad or
we've done something wrong.
I've moved the code directly into `try_load_from_mapped_file()` since
`load_from_memory()` was only called from there. The extra indirection
wasn't adding anything.
Turns out this was hurting performance instead of helping it.
By removing the inline capacity, we shrink the size of ExecutionContext
by 512 bytes, which substantially reduces the stack pressure created by
JS recursion (each call creates a new ExecutionContext on the stack).
4.4% speed-up on the entire Kraken benchmark :^)
Previously every file that included Executable.h (which is pretty much
most LibJS and LibHTML files, given that VM.h needs it) had the whole
definition of LibRegex, which was slowing down source parsing.
Window.h is a rather heavy file, so let's try not to include it in
header files when we can!
Element.h now also includes LibWeb/Bindings/Intrinsics.h, but that's
just out of my laziness. Most if not all objects call
`Bindings::ensure_web_prototype<>()` anyway, so I don't think we would
gain much by sticking the header to source files instead.
We needed to keep the old versions of these functions around before all
of the IDL interfaces were ported over to new AK String, but now that is
done, we can remove the deprecated versions of these functions.
