We were trying to take a shortcut by avoiding much of the flex layout
algorithm during intrinsic sizing. Unfortunately, this isn't good enough
since we may end up needing some of the flex item metrics for intrinsic
contribution calculations.
This means we do a bit more work for flexboxes, but intrinsic sizes are
correct in more cases.
Nobody tests this network card, and the driver has bugs (see the issue
https://github.com/SerenityOS/serenity/issues/10198 for more details),
so it's almost certain that this happened due to code being rotting when
there's simply no testing of it.
Essentially this has been determined to be dead-code so this is the most
important reason to drop this code. Another good reason to do so is
because the RTL8139 only supports Fast Ethernet connections (10/100
Megabits per second), and is considered obsolete even for bare metal
setups.
This allows us to make all comparision operators on the class constexpr
without pulling in a bunch of boilerplate. We don't use the `<compare>`
header because it doesn't compile in the main serenity cross-build due
to the include paths to LibC being incompatible with how libc++ expects
them to be for clang builds.
We changed elapsed() to return i64 instead of int as that's what
AK::Time::to_milliseconds() returns, causing a bunch of implicit lossy
conversions in callers. Clean those up with a mix of type changes and
casts.
Integer seconds are cool, but the comparison is a lot easier to
understand when stored as an AK::Time, and converted from_seconds()
after parsing the timeout from the command line.
We don't need to be checking the current time unconditionally when we
only observe the results if we're going to dump the GC stats.
This saves two trips to clock_gettime at the cost of an extra branch.
Simplify a lot of uses of ElapsedTimer by converting the callers to
elapsed_time from elapsed, as the AK::Time returned is better for unit
conversions and comparisons against constants.
This removes the direct dependency on sys/time.h from ElapsedTimer, and
makes the code a lot cleaner by using the helpers from AK::Time for
time math and getting the current timestamp.
Namely:
- preferred CMM type
- device manufacturer
- device model
- profile creator
These all have in common that they can take arbitrary values, so I added
a FourCC class to deal with them, instead of using an enum class.
I made distinct types for each of them, so that they aren't accidentally
mixed up.
The previous implementation of Statistics::median() was slightly
incorrect with an even number of elements since in those cases it needs
to be the arithmetic mean of the two elements that share the middle
position.
Instead of using a clunky if-statement paradigm, we now have all drivers
being declaring two methods for their adapter class - create and probe.
These methods are linked in each PCINetworkDriverInitializer structure,
in a new s_initializers static list of them.
Then, when we probe for a PCI device, we use each probe method and if
there's a match, then the corresponding create method is called. After
the adapter instance is created, we call the virtual initialize method
on it, because many drivers actually require a sort of post-construction
initialization sequence to ensure the network adapter can properly
function.
As a result of this change, it's much more easy to add more drivers and
the initialization code is more readable and it's easier to understand
when and where things could fail in the whole initialization sequence.
Instead of allocating those regions in the constructor, which makes it
impossible to fail in case of OOM condition, allocate them in the static
factory method so we could propagate errors in case of failure.
Instead of allocating after the construction point ensure that all Intel
drivers are allocating necessary buffer regions and then pass them to
the constructors.
This could let us fail early in case of OOM, so we don't touch a network
adapter before we ensure we have all the appropriate mappings in place.
This patch reimplements the now deprecated try_open_file(),
try_request_file() and try_request_file_read_only_approved() functions,
with the difference that the new ones return a FSAC::File object
(currently a wrapper with a Core::Stream and a filename) instead of a
Core::File.
Implemented in a similar manner to 6dd716adf2.
The new result returned just a file stream, which wasn't sufficient
enough for most applications because it didn't provide a filename.
This patch will make a new File object that has both a file stream and
a filename.
These functions return the deprecated `Core::File` class, so let's mark
it as such to avoid possible confusion between future non try_*
functions which will use Core::Stream family classes and to possibly
grab someone's attention. :^)
This tab allows you to view the accessibility tree like you do
the DOM tree. The implementation limited to the role currently,
once we add the name and description calculation algorithm, those
will be displayed here as well. Selections are also not currently
supported.
This patch also stubs out notify_server_did_get_accessiblity_tree in
ladybird since ViewImplementation now has it. However, this feature
is still immature, so just stubbing out in ladybird for now. Once we
have more robust support in Serenity (namely ARIA properties/state
and accessible names and descriptions) we can port this
functionality over.
With this patch, the accessibility tree can be build from the root
node of a document. This can then be serialzed and sent to (soon
to come) consumers.
When we were asked to make a new preview text, we first generated the
whole file in the /tmp directory and then read the first 8 lines to put
them in a text box. This was doing a bit of unnecessary work at first,
but more importantly, didn't work on a given file descriptor from
FileSystemAccessServer as we were copying a file to a filename instead,
meaning that we also had to unveil the whole home directory.
Anyway, previews will be written now to a MemoryStream by the generator,
which will limit to 8 lines. File saves will omit /tmp entirely,
allowing us to tighten program unveil list a little. :^)
