The SQL engine is expected to be a fairly sizeable piece of software.
Therefore we're starting to restructure the codebase for growth.
|
|
Namely MD5, SHA1, SHA256, SHA384 and SHA512.

Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.

Previously ByteBuffer::grow() behaved like Vector<T>::resize().
However the function name was somewhat ambiguous - and so this patch
updates ByteBuffer to behave more like Vector<T> by replacing grow()
with resize() and adding an ensure_capacity() method.
This also lets the user change the buffer's capacity without affecting
the size which was not previously possible.
Additionally this patch makes the capacity() method public (again).

This fixes a few compiler warnings and makes some variables const-ref
in preparation for the next commit which changes how ByteBuffer works.

Previously the directions omitted that you have to specify
`-CMAKE_CXX_COMPILER` when building the Fuzzers. This
would cause all kinds of weird problems at compilation and
link time. You can't specify one or the other, they must
both be pointing at clang in order for things to work as
experted. Fix this by updating the documentation to specify
that the user should specify both the C and CXX compiler explicitly
to be safe, as well as forcing the cmake clang argument handling
to modify the CXX compiler variable instead of the C version.

This function was shadowing Object::initialize() which cannot be called
on global objects and has a different set of parameters.

No fuzzer for UTF-8 as it (currently) just returns the input.
|

Adds fuzzers for Deflate, Gzip and Zlib.

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.

First issue: #5317

Arbitrarily split up to make git bisect easier.
These unnecessary #include's were found by combining an automated tool (which
determined likely candidates) and some brain power (which decided whether
the #include is also semantically superfluous).
|
|
|
|
-fsanitize=fuzzer was being added to LINKER_FLAGS from Lagom/CMakeLists,
which we don't want with FuzzilliJs as we want to define the functions
it provides ourselves.
|
|
These changes are arbitrarily divided into multiple commits to make it
easier to find potentially introduced bugs with git bisect.Everything:
The modifications in this commit were automatically made using the
following command:
find . -name '*.cpp' -exec sed -i -E 's/dbg\(\) << ("[^"{]*");/dbgln\(\1\);/' {} \;
|
|
This should help us get a lot more coverage in LibJS.

This commit gets rid of ELF::Loader entirely since its very ambiguous
purpose was actually to load executables for the kernel, and that is
now handled by the kernel itself.
This patch includes some drive-by cleanup in LibDebug and CrashDaemon
enabled by the fact that we no longer need to keep the ref-counted
ELF::Loader around.

Problem:
- `(void)` simply casts the expression to void. This is understood to
indicate that it is ignored, but this is really a compiler trick to
get the compiler to not generate a warning.
Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.
Note:
- Functions taking a `(void)` argument list have also been changed to
`()` because this is not needed and shows up in the same grep
command.

This allows us to get rid of some ByteBuffer::wrap() usage.

There are cases where Lagom will build with GCC but not Clang.
This often goes unnoticed for a while as we don't often build with
Clang.
However, this is now important to test in CI because of the
OSS-Fuzz integration.
Note that this only tests the build, it does not run any tests.
Note that it also only builds LagomCore, Lagom and the fuzzers.
It does not build the other programs that use Lagom.

This was broken with the JS::Parser::Error position changes, but I don't
actually see a reason to do anything with the parser errors here, so
let's remove it and consider simply not crashing a success. :^)

It finds the problem fixed in 69518bd178ebfaa but nothing else.
|

Didn't find anything interesting, but might as well check it in.

Based on Fedora. This allows building and running FuzzilliJs and Fuzzilli
itself in a Docker/Podman container.
