Implements: tc39/proposal-temporal@261692a
In order to remove the call to to_positive_integer() there neeeded
to be a change of return type from ThrowCompletionOr<Value> to
ThrowCompletionOr<double>.
This is one of the changes that will come anyways with the following
commit: tc39/proposal-temporal@11aad40. :^)
Previously, trying to load a wav file in aplay or SoundPlayer with a
sample rate less than 44100 would crash in an assertion failure trying
to unchecked_append to a vector that was not resized properly.
Check if the process we are currently running is in a jail, and if that
is the case, fail early with the EPERM error code.
Also, as Brian noted, we should also disallow attaching to a jail in
case of already running within a setid executable, as this leaves the
user with false thinking of being secure (because you can't exec new
setid binaries), but the current program is still marked setid, which
means that at the very least we gained permissions while we didn't
expect it, so let's block it.
We didn't take the scroll value into account when we were converting
a position to an index, which basically prevented us from selecting a
desired file if a list wasn't small enough to fit entirely in the widget
box.
The hand-written assembly does not compile under Clang due to register
size mismatches. Using a loop is slower (~6 instructions on O2 as
opposed to 2 with hand-written assembly), but using the pause
instruction makes this more efficient even under TCG.
For pause we use isb sy which will put the processor to sleep while the
pipeline is being flushed. This instruction is also used by Rust in spin
loops and found to be more efficient, as well as being a rough
equivalent to the x86 pause instruction which we also use here.
For wait_check we use yield, which is a hinted nop that is faster to
execute, and I leave a FIXME for processing SMP messages once we support
SMP.
These two changes probably make spin loops work on aarch64 :^)
Implement collapsing of a box margin-top and first in-flow
child margin-top by saving function that updates y position
of containing block inside BlockMarginState and then for
every child until "non-collapsed through" child is reached
y position of containing block is updated by calling
update_box_waiting_fox_final_y_position_callback.
Previously y position of boxes in block formatting context
was calculated by looking at y position of previous in-flow
sibling and adding collapsed margin of "collapse through"
boxes lying between box currently being laid out and it's
previous in-flow sibling.
Here introduced BlockMarginState structure that maintains
array of currently collapsible margins hence we no longer
need to look at previous sibling to calculate y position
of a box.
It may be handy to have some sort of storage inspector at some point but
for now, it doesn't make sense to open a database file. So only allow
opening script files, and don't make assumptions on their extension.
This adds a combo box to the action toolbar to allow for entering a
database name manually or selecting from the list of existing databases.
The action to run a script is now disabled while we are not connected to
a database.
It's not particularly useful to see the word count of a SQL script,
except for when displaying the number of selected words. This changes
SQLStudio to behave exactly like HackStudio in this regard. We will use
segment 0 to display the selected text stats (if any) and segment 2 for
the cursor position. Segment 1 will be used in an upcoming commit for
the current SQL connection status. We also now handle displaying action
text the same way as HackStudio.
Most actions do not need to care about whether there is an open editor
tab, as we can (and should) disable those actions when there isn't an
open tab. We can also hide the verify_cast handling inside a helper
function.
The underlying Core::Stream methods require the bytes passed in to be
non-empty. Simply opening the file is enough to ensure the file is
created with empty contents if the editor's text is empty.
In both applications, display the SQL statement that failed to parse.
For the REPL, ensure the REPL prompts the user for another statement.
For SQLStudio, we don't continue executing the script as it likely does
not make sense to run statements that come after a failed statement.
Otherwise the `move(result)` statement inside the lambda does not
actually move anything, because `result` is constant without the mutable
attribute. Caught by clangd.
These are currently hitting the `decltype(nullptr)` constructor, which
marks the response as invalid, resulting in no response being sent to
the waiting client.
This commit changes the init.cpp file to start and initialize the
Scheduler, and actually runs init_stage2. To show that it actually
works, another thread is spawned and executed simultaneously, by context
switching between the two!
This requires two new functions, context_first_init and
restore_context_and_eret. With this code in place, we are now running
the first idle thread! :^)
This changes the stack pointer to the initial_thread stack pointer, and
pushes two pointers onto the stack that point to the initial_thread. The
function then jumps to the ip of the initial_thread, which will be
thread_context_first_enter, and hangs there because that function is not
yet implemented.
This does not handle everything correctly yet, such as setting the
correct state for running userspace applications, however this should be
enough to get kernel scheduling to work.
