StyleValueList is a list of StyleValues of the same type, for use in
properties like `margin` which accept a variable number of arguments.
I had originally hoped to simply swap the old ValueListStyleValue from
being a list of ComponentValues to one of StyleValues, but I can see now
that I will need to have both for a little while, so renamed the old
is_value_list() to is_component_value_list() temporarily.
I had accidentally parsed it in `parse_builtin_or_dynamic_value()`
instead of `parse_length()` before, which was confusing, so now it's
parsed along with other Lengths.
Whether it should be a Length is up for debate, and has been tripping me
up a few times, but a lot of code expects it to be one. For now, an
'auto' Length value (or any other value which overloads `is_auto()`)
also claims to be a `ValueID::Auto` identifier.
A '0' token can be interpreted both as a Number, and as a Length. This
is problematic as in our CSS parser, we often call parse_css_value()
first, to figure out what something is, and then assign it. So we do not
know in advance whether we want a Length or not. Previously, it always
got parsed as a Length, and then every place that expected a
NumericStyleValue had to also check for a Length(0), which is easy to
forget to do.
In particular, this was causing issues with the `flex` property parsing.
To solve this, we now always parse 0 as a NumericStyleValue, and NSVs of
0 pretend to be a Length(0px) when asked. In two places, we were casting
to a LengthStyleValue* based on is_length(), which no longer works, so
those have been adjusted to use `StyleValue::to_length()` instead. They
also now check for `is_numeric()` first, to avoid the extra conversion
to a Length and back.
Possibly this opens up new issues elsewhere. In my testing it seems
fine, but until we can get CSS test suites running, it's hard to know
for certain.
Similarly to the LibCpp parser regression tests, these tests run the
preprocessor on the .cpp test files under
Userland/LibCpp/Tests/preprocessor, and compare the output with existing
.txt ground truth files.
The preprocessor now understands when a function-like macro is defined,
and can also parse calls to such macros.
The actual evaluation of function-like macros will be done in a
separate commit.
Instead of keeping a separate Vector<Event> for signposts, let them live
in the main event stream. For fast iteration, we instead keep a cache of
the signpost event indices.
The C++ standard specifies that `free` and `operator delete` should
be callable with nullptr. The non-aligned `kfree` already handles this,
but because of the pointer arithmetic to obtain the allocation start
pointer, the aligned version would produce undefined behavior.
In e7fb70b05, regular kmalloc was changed to return nullptr on
allocation failure instead of crashing. The `kmalloc_aligned_cxx`
wrapper used by the aligned operator new should do the same.
When building a port as a dependency for another port the HOST_*
variables were previously initialized with values referring to the
SerenityOS toolchain.
Fixes#9168.
In #9373, /usr/local/bin was added to the unveiled directories to make
symbolization work on ports. This directory only exists if at least one
port is installed, so unveil would fail with ENOENT if we had none.
Enable the LOCK_DEBUG functionality for these new APIs, as it looks
like we want to move the whole system to use this in the not so distant
future. :^)
The LOCK_DEBUG conditional code is pretty ugly for a feature that we
only use rarely. We can remove a significant amount of this code by
utilizing a zero sized fake type when not building in LOCK_DEBUG mode.
This lets us keep the same API, but just let the compiler optimize it
away when don't actually care about the location the caller came from.
Calling error() on KResult is a mistake I made in 7ba991dc37, so
instead of doing that, which triggers an assertion if an error occured,
in Inode::read_entire method with VERIFY(nread <= sizeof(buffer)), we
really should just return the KResult and not to call error() on it.
This script will instantiate a HackStudio template into a project on the
host. It currently supports all templates used by HackStudio.
To avoid having to maintain compatibility between other shells and the
Serenity shell in the postcreate scripts, we build the Serenity shell
with Lagom and use that to run the script.
Previously the system would assume the socket was connected after the
file descriptor became writeable. Just because the fd is signaled as
ready for output does not necessarily indicate the socket is connected.
Instead, we should check the status of the socket with SO_ERROR and
handle successes/errors accordingly.
When TCP sockets successfully establish a connection, any SO_ERROR
should be cleared back to success. For example, SO_ERROR gets set to
EINPROGRESS on asynchronous connect calls and should be cleared when
the socket moves to the Established state.
Adds netstat command line argument to display slash-separated pair of
the id and name of the process that owns the socket. User must have
superuser privileges to see information on non-owned sockets.
This allows for commands like netstat to reference /proc/net and
identify a connection's owning process. Process information is limited
to superusers and user owned processes.
Previously, libcurl is not used in the git build because the test
program in configure fails to link against it properly. We bypass the
test and make sure we link against all necessary libraries (libssl,
libcrypto and zlib).
Previously, the git port would fail in various ways because it uses an
uname detection mechanism to update the configurations, and Makefile
would receive incorrect configurations from the host system. This makes
sure the build uses the correct configurations detected by ./configure.
Fixes#9357.
