- UBSAN detected cases where we were calling thread->holding_lock(..)
but current_thread was nullptr.
- Fix Lock::force_unlock_if_locked to not pass the correct ref delta to
holding_lock(..).
As many macros as possible are moved to Macros.h, while the
macros to create a test case are moved to TestCase.h. TestCase is now
the only user-facing header for creating a test case. TestSuite and its
helpers have moved into a .cpp file. Instead of requiring a TEST_MAIN
macro to be instantiated into the test file, a TestMain.cpp file is
provided instead that will be linked against each test. This has the
side effect that, if we wanted to have test cases split across multiple
files, it's as simple as adding them all to the same executable.
The test main should be portable to kernel mode as well, so if
there's a set of tests that should be run in self-test mode in kernel
space, we can accomodate that.
A new serenity_test CMake function streamlines adding a new test with
arguments for the test source file, subdirectory under /usr/Tests to
install the test application and an optional list of libraries to link
against the test application. To accomodate future test where the
provided TestMain.cpp is not suitable (e.g. test-js), a CUSTOM_MAIN
parameter can be passed to the function to not link against the
boilerplate main function.
This is useful for CI where we don't want to spend a minute and a half
benchmarking Vector::append, and we don't have a good way to pass
test-specific arguments yet. :)
This patch removes the IPC endpoint numbers that needed to be specified
in the IPC files. Since the string hash is a (hopefully) collision free
number that depends on the name of the endpoint, we now use that
instead. :^)
I have my environment configured to use https://pre-commit.com/.
I guess the scripts were changed recently to lint all ports, and
the python port was barfing on my system because of this bug.
Commit b3db01e20 broke simple commands without arguments like:
./package.sh clean
Now, all available arguments are passed along, even if there are none.
Userspace can provide a null argument for the `act` argument to the
`sigaction` syscall to not set any new behavior. This is described
here:
https://pubs.opengroup.org/onlinepubs/007904875/functions/sigaction.html
Without this fix, the `copy_from_user(...)` invocation on `user_act`
fails and makes the syscall return early.
C++20 added std::source_location, which lets you capture the
callers __FILE__ / __LINE__ / __FUNCTION__ etc as a default
argument to functions.
See: https://en.cppreference.com/w/cpp/utility/source_location
During a bug investigation @ADKaster suggested we could use this
to make the LOCK_DEBUG feature of the kernel more user friendly
and allow it to automatically instrument all call sites.
We then implemented / tested it over discord. :^)

LibWeb is now responsible for logging unhandled exceptions itself,
which means set_should_log_exceptions() is no longer used and can be
removed. It turned out to be not the best option for web page exception
logging, as we would have no indication regarding whether the exception
was later handled of not.
Instead of having to run queued promise jobs in LibWeb in various
places, this allows us to consolidate that into one function - this is
very close to how the spec describes it as well ("at some future point
in time, when there is no running execution context and the execution
context stack is empty, the implementation must [...]").
Eventually this will also be used to log unhandled exceptions, and
possibly other actions that require JS execution to have ended.
Instead of storing the function names (in a badly named Vector<String>)
and source ranges separately, consolidate them into a new struct:
TracebackFrame. This makes it both easier to use now and easier to
extend in the future.
Unlike before we now keep each call frame's current node source range
in the traceback frame next to the function name, meaning we can display
line and column numbers outside of the VM and after the call stack is
emptied.
This would return an empty value once it hits an exception check
otherwise. Considering that this mostly is used in situations where we
already *do* have an exception (traceback printing, for example), let's
make this easier for ourselves to use.
This is very similar to AK::TemporaryChange (and in fact replaces one
use of it), but since we can't directly set VM's m_exception from
outside of the VM, we need something more sophisticated.
Sometimes we need to temporarily remove the stored exception for some
other operation to succeed (e.g. anything that uses call(), as well as
get_without_side_effects()) and later restore it - the boilerplate code
required for this is annoying enough to justify a helper.
Correct the order we pass the arguments to the FileManager so
opening file:// URLs works.
The path is a positional argument that was passed after the flags.
We need to make sure the flags are passed before positional arguments.
Previously a Painter's m_clip_origin field was initialized to a
widget's window_relative_rect, which is not ensured to be within
the target rect.
m_clip_origin is normally not used for clipping, but after calling
clear_clip_rect the clip rect that IS used for clipping gets reset
to m_clip_origin (so an invalid state is entered).
Now the window_relative_rect will be clipped by the target rect
first, and will only then be used to initialize both the active
clip_rect and m_clip_origin.
The EXISTS expression is a bit of an odd-man-out because it can appear
as any of the following forms:
EXISTS (select-stmt)
NOT EXISTS (select-stmt)
(select-stmt)
Which makes it the only keyword expression that doesn't require its
keyword to actually be used. The consequence is that we might come
across an EXISTS expression while parsing another expression type;
NOT would have triggered a unary operator expression, and an opening
parentheses would have triggered an expression chain.
Currently, every parse_*_statement method ends by parsing a semi-colon.
This will prevent nested statements, e.g. a SELECT statement may be
nested in a CREATE TABLE statement. Move the semi-colon expectation up
and out of the individual statement parsers.
Another common semantic is parsing an identifier of the form
"schema_name.table_name" / "table_name". Add a helper to do this work.
This helper does not parse any optional alias after the table name.
some syntaxes specify an alias using the AS keyword, some let the AS
keyword be optional, and others just parse it as an identifier. So
callers to this helper will just continue parsing the alias however
they require.
A quite common semantic emerged for parsing comma-separated expressions:
consume(TokenType::ParenOpen);
do {
// do something
if (!match(TokenType::Comma))
break;
consume(TokenType::Comma);
} while (!match(TokenType::Eof));
consume(TokenType::ParenClose);
Add a helper to do the bulk of the while loop.
