This is very useful for discovering collector bugs.

|
Let's try to keep LibJS tidy as it expands. :^)
|
|
ioctl can now perform a request for a specific route and change
the address of it's default gateway.

Now that we have the beginnings of a parser, let's take the script to
run as a command-line argument and move all the test scripts into
/home/anon/js :^)
To run a script, simply use "js":
$ js my-script.js
To get an AST dump before execution, you can use "js -A"

This adds a basic Javascript lexer and parser. It can parse the
currently existing demo programs. More work needs to be done to
turn it into a complete parser than can parse arbitrary JS Code.
The lexer outputs tokens with preceeding whitespace and comments
in the trivia member. This should allow us to generate the exact
source code by concatenating the generated tokens.
The parser is written in a way that it always returns a complete
syntax tree. Error conditions are represented as nodes in the
tree. This simplifies the code and allows it to be used as an
early stage parser, e.g for parsing JS documents in an IDE while
editing the source code.:

A new IP address or a new network mask can be specified in the command
line arguments of ifconfig to replace the old values of a given network
adapter. Additionally, more information is being printed for each adapter.

Previously, we were assuming all declared variables were bound to a
block scope, now, with the addition of declaration types, we can bind
a variable to a block scope using `let`, or a function scope (the scope
of the inner-most enclosing function of a `var` declaration) using
`var`.

The above snippet is a MemberExpression that necessitates the implicit
construction of a StringObject wrapper around a PrimitiveString.
We then do a property lookup (a "get") on the StringObject, where we
find the "length" property. This is pretty neat! :^)

Change the date in the copyright.

It's now possible to assign expressions to variables. The variables are
put into the current scope of the interpreter.
Variable lookup follows the scope chain, ending in the global object.

The '-L' option can be used for calling stat instead of lstat

Use this instead of uintptr_t throughout the codebase. This makes it
possible to pass a FlatPtr to something that has u32 and u64 overloads.

I always tell people to start building things by working on the thing
that seems the most interesting right now. The most interesting thing
here was an AST + simple interpreter, so that's where we start!
There is no lexer or parser yet, we build an AST directly and then
execute it in the interpreter, producing a return value.
This seems like the start of something interesting. :^)

Let's rename this to LibWeb since it aims to provide more parts of the
web platform than just HTML. :^)
|

|
|
LibCore's GZip is also moved into the Core namespace with this change.
|
|
|
|
Also, lsirq will return more useful data than lsinterrupts did

Avoid creating SingleIndexes in case of byte ranges. This, boosts
the performance significantly in case a byte range is too big(e.g 666-123123).
Also, claim copyright over this mess since I am the one responsible for it.

Now it actually defaults to "a < b" comparison, instead of forcing you
to provide a trivial less-than comparator. Also you can pass in any
collection type that has .begin() and .end() and we'll sort it for you.
|

The following options are now available:
-e: Show every process (not just the ones on your TTY)
-f: Full format (instead of the short format)
We should definitely support more options and formats, I just wanted to
get away from the static single style of output. :^)

Now that Vector uses size_t, we can remove a whole bunch of redundant
casts to size_t.

Fixes #1278.

Fixes #1262

You can now profile a program from start to finish by doing:
$ profile -c "cat /etc/passwd"
The old "enable or disable profiling for a PID" mode is accessible via:
$ profile -p <PID> -e # Enable profiling for PID
$ profile -p <PID> -d # Disable profiling for PID
The generated profile is available via /proc/profile like before.
This is far from perfect, but it at least makes profiling a lot nicer
to use since you don't have to hurry and attach to something when you
want to profile the whole thing anyway.

In the code below, db could be null, and would cause UB.
Instead of crashing, let's simply skip symbolicating names.
Fixes #1247

Fixes #1246.

This matches what we already do for string types.
