This makes un-styled text readable when using a dark system theme,
previously such text would be black, regardless of the theme background
color.
Fixes#7274.
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.
Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.
We also check that there were no parser errors when parsing the .cpp
files.
Previously, ASTNode::dump() used outln() for output, which meant it
always wrote its output to stdout.
After this commit, ASTNode::dump() receives an 'output' argument (which
is stdout by default). This enables writing the output to somewhere
else.
This will be useful for testing the LibCpp Parser with the output of
ASTNode::dump.
Hook the kernel page fault handler and capture page fault events when
the fault has a current thread attached in TLS. We capture the eip and
ebp so we can unwind the stack and locate which pieces of code are
generating the most page faults.

Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
Instead of sprinkling the definition of the ciper suites all over the
TLS implementation, let's regroup it all once and for all in a single
place, and then add our new implementations there.
This patch implements the HTML specification's "encoding sniffing
algorithm", which is used when no encoding can be obtained from the
Content-Type header (either because it doesn't contain a charset=...)
value or the file has not been opened via HTTP (as with local files).
It also modifies the creator of the HTMLDocumentParser to use the new
HTMLDocumentParser::create_with_uncertain_encoding static method, which
runs the encoding sniffing algorithm before instantiating the parser.
This now allows us to load local HTML pages (or remote pages without a
charset specified in the 'Content-Type' header) with a non-UTF-8
encoding such as 'windows-1252'. This would previously crash the
browser. :^)
This modifies the Document class to use Optional<String> for the
encoding. If the encoding is unknown, the Optional will not have a
value. It also implements the has_encoding() and encoding_or_default()
instance methods, the latter of which will return "UTF-8" as a fallback
if no encoding is present.
The usage of Optional<String> instead of the null string is part of an
effort to explicitly indicate that a string could not have a value.
This also modifies the former callers of encoding() to use
encoding_or_default(). Furthermore, the encoding will now only be set if
it is actually known, rather than just guessed by earlier code.
This modifies the Resource class to use Optional<String> for the
encoding. If the encoding is unknown, the Optional will not have a
value (instead of using the null state of the String class). It also
implements a has_encoding() instance method and modifies the callers
of Resource::encoding() to use the new API.
This patch changes the encoding_from_content_type function to only
return an encoding if it actually finds one, and leave it up to the
caller to decided on a default to use.
It also modifies the caller to expect an Optional<String> (instead of
relying on the null state of the String class) as a return value and
separates the encoding and MIME type determination. This will be built
upon in a further commit.
This patch changes get_standardized_encoding to use an Optional<String>
return type instead of just returning the null string when unable to
match the provided encoding to one of the canonical encoding names.
This is part of an effort to move away from using null strings towards
explicitly using Optional<String> to indicate that the String may not
have a value.
Second batch of detectable formats, this time with verious offsets, as
enabled by the previous commit.
This adds tar, and the three signature variants for iso-9660 image
files.
This commit adds the Renderer class, which is responsible for rendering
a page into a Gfx::Bitmap. There are many improvements to make here,
but this is a great start!
