According to the definition at https://sqlite.org/lang_expr.html, SQL
expressions could be infinitely deep. For practicality, SQLite enforces
a maxiumum expression tree depth of 1000. Apply the same limit in
LibSQL to avoid stack overflow in the expression parser.
Fixes https://crbug.com/oss-fuzz/34859.
The specification requires that we immediately return Infinity during
the iteration over the arguments if positive or negative infinity is
encountered, and return a NaN if it is encountered and no Infinity was
found. The specification also requires all arguments to be coerced into
numbers before the operation starts, or else a number conversion
exception could be missed due to the Infinity/NaN early return.

The PCRE JIT creates memory that needs to be readable, writable and
executable at the same time. Serenity does not like this, so disable
it. This JIT is of limited use for the current applications of PHP
within Serenity anyway :-)
Previously, we would echo characters back just as they were passed to
us, even in canonical mode. This caused newlines to not work correctly
in some programs.

When clicking on the TreeView in profiler without selecting a node and
then pressing up or pgup, cursor_index was in an invalid state. Instead
select the first node in the index.
On most (if not all) systems rm ignores an empty paths array if -f or
--force is specified. This helps with scripts that may pass an empty
variable where the file paths are supposed to go.
This changes URL parser to use the 0xFFFFFFFF constant instead of 0 to
indicate end of file. This fixes a bug where inputs containing null
bytes would terminate the parser early, because they were interpreted
as end of file.
This patch adds a state_name method to URLParser to convert a state to a
string. With this, the debugging statements now display the state names.
Furthermore, this fixes a bug where non-ASCII code points were
formatted as characters, which fails an assertion in the formatting
system.
Because non-ASCII code points have negative byte values, trimming away
control characters requires checking for negative bytes values.
This also adds a test case with a URL containing non-ASCII code points.

TMPDIR This variable shall represent a pathname of a directory made
available for programs that need a place to create temporary
files.
Ports like PHP benefit from having this environment variable set, and
there exist a lot of scripts that assume the presence of such an
environment variable.
This changes the C++ SyntaxHighlighter to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor.
Contrary to other syntax highlighters, for this one the change has been
made to the SyntaxHighlighter rather than the Lexer. This is due to the
fact that the Parser also uses the same Lexer. I'm soure there is some
more elegant way to do this, but this patch at least unbreaks the C++
syntax highlighting.
If an include statement didn't contain whitespace between the word
"include" and the '<' or '"', the lexer would previous emit an empty
whitespace token. This has been changed now.
This patch aims to fix wrong highlighting for some cases in HTML's
syntax highlighter. The values were somewhat experimentally determined
are are subject to change. Regardless, it should be more correct with
this patch than without it. :^)
This changes the HTML SyntaxHighlighter to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor. It also
avoids emitting tokens if they have a zero or negative length.
This fixes a bug where single-character tokens were not highlighted
properly.
This patch changes HTMLTokenizer::nth_last_position to not fail if the
requested position is not available. Rather, it will just return (0-0).
While this is not the correct solution, it prevents the tokenizer from
crashing just because it cannot find a source position. This should only
affect SyntaxHighlighter.
This changes the Shell syntax highlighter to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor.
This also adds some debug output to make debugging easier.
This changes the INI and GML lexers to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor.
The other user of GMLToken::m_end, GMLAutocompleteProvider, has been
modified to take into account that end position columns have been
incremented by one.
