Instead of assuming that we should use the OSC 9 progress messages
whenever we run on serenity, add a show-progress=[true|false] option.
This lets us avoid seeing esc sequence spam in GitHub Actions logs.
The test-js reporter is arguably the nicest test runner / reporter that
exists in the serenity code base. To the goal of leveling up all the
other unit test environments, start a new LibTest library so that we
can share code and reporting utilities to make all the test systems
look and behave similarly.
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
Thanks to @trflynn89 for the neat implicit consteval ctor trick!
This allows us to basically slap `CheckedFormatString` on any
formatting function, and have its format argument checked at compiletime.
Note that there is a validator bug where it doesn't parse inner replaced
fields like `{:~>{}}` correctly (what should be 'left align with next
argument as size' is parsed as `{:~>{` following a literal closing
brace), so the compiletime checks are disabled on these temporarily by
forcing them to be StringViews.
This commit also removes the now unused `AK::StringLiteral` type (which
was introduced for use with NTTP strings).
There's no point in using different, seemingly randomly sized buffers as
the required size for storing an IPv4 address representation is well
known (16 bytes).
This achieves two things:
- Programs can now intentionally perform arbitrary syscalls by calling
syscall(). This allows us to work on things like syscall fuzzing.
- It restricts the ability of userspace to make syscalls to a single
4KB page of code. In order to call the kernel directly, an attacker
must now locate this page and call through it.
Since this is useful in many places, let's have a common implementation
of walking the stack of a given thread via /proc and symbolicating each
of the frames.
The /boot directory is only accessible to root by default, but anyone
wanting access to kernel symbols for development can get them by making
/boot/Kernel accessible to the "symbol" user.
Usage: bt <PID>
This program will print a symbolicated backtrace for the main thread of
the process with the given PID. It uses SymbolServer for the
symbolication.
There's a lot of room for improvement in this command, but it is pretty
neat already. :^)
If an exception was thrown while printing the last computed value in
the REPL, it would always assert on next input.
Something like this would always assert:
> a=[];Object.defineProperty(a,"0",{get:()=>{throw ""}})
> 1 + 2
