The values aren't 100% self-consistent, but it probably doesn't make
a difference for u8 color data. Good enough for now. See all the links
on #17714 for some more background.
This creates folding regions for blocks defined by the following:
- if/elseif/else/endif
- foreach/endforeach
- while/endwhile
- macro/endmacro
- function/endfunction
Since there is no guarantee that each keyword will have a matching
partner, we do our best by looking for the most recent possible start
token matching the current end token. If we find one, we link to it and
drop all the other start-tokens that happened in between. For example,
we would define a folding region for this invalid file like so:
[-] if(TRUE)
│ while()
└─ endif()
This sorts the array of generated emoji data by code point (first by
code point length, then by code point value). This lets us use a binary
search to find emoji data, rather than the current linear search.
In a profile of scrolling around /home/anon/Documents/emoji.txt, this
reduces the runtime of Gfx::Emoji::emoji_for_code_points from 69.03% to
28.42%. Within that, Unicode::find_emoji_for_code_points reduces from
28.42% to just 1.95%.
Before of this patch, we looked at the unveil data of the FinalizerTask,
which naturally doesn't have any unveil restrictions, therefore allowing
an unveil bypass for a process that enabled performance coredumps.
To ensure we always check the dumped process unveil data, an option to
pass a Process& has been added to a couple of methods in the class of
VirtualFileSystem.
You can generate one by using `cjpeg` with the -scan argument.
This image has been generated with the following scan file:
0 1 2: 0 0 0 0;
0: 1 9 0 0;
2: 1 63 0 0 ;
1: 1 63 0 0 ;
0: 10 63 0 0;
Calling it was harmless as add_ac iterates over the spectral selection,
hence it won't do anything if not needed. However, this patch remains
useful as it prevents dereferencing the iterator returned by find, in
case the AC table isn't defined yet. This case happens with SOF2 images
and is (pretty harmless as read only but still) undefined behavior.
This patch brings support for SOF2 JPEGs that only use spectral
selection :^)
We still don't have achieved full support for SOF2 images, but as an
example, we decode progressive JPEG from Cloudinary.
