Let's be consistent with the rest of LibJS (and the rest of the file).
|
|
This changes browsing through disassembled functions in Profiler from a
painfully sluggish experience into quite a swift one. It's especially
true for profiling the kernel, as it has more than 10 megabytes of DWARF
data to churn through.
|
|
/boot/Kernel.debug only contains the symbol table and DWARF debug
information, and has its `.text` and other PT_LOAD segments stripped
out. When we try to parse its data as instructions, we get a crash from
within LibX86.
We now load the actual /boot/Kernel binary when we want to disassemble
kernel functions.
|
|
There is no point in keeping around a separate MappedFile object for
/boot/Kernel.debug for each DisassemblyModel we create and re-parsing
the kernel image multiple times. This will significantly speed up
browsing through profile entries from the kernel in disassembly view.
|
|
This also required converting URLSearchParams::for_each and the callback
function it invokes to ThrowCompletionOr. With this, the ReturnType enum
used by WrapperGenerator is removed as all callers would be using
ReturnType::Completion.

For file copying, when there is a file with the same name in the
destination directory, the file will be automatically renamed to
"file-2.txt", for example. This change expands that special-case
handling to file moving.

Before this patch less would query the terminal geometry only at
startup and use this information to render the file when
appropriate. If the terminal is resized then the output is broken in
several different ways because of this.
This patch adds a SIGWINCH signal handler receive notification any
time the terminal is resized. This signal handler just sets a flag to
notify the main loop that a resize has occurred.
The main loop of the program just calls get_key_sequence() to get
input from the user, interpreting keystrokes as commands like scroll
up or down. The get_key_sequence() function has been changed to return
Optional<String>, so it either returns a keystroke from the user or it
returns nothing as an empty Optional.
While the user is not pressing any keys on the keyboard, the program
is blocking on a read() system call in get_key_sequence(). When
SIGWINCH is received, this read() will return with -1 and errno is set
to EINTR since the system call was interrupted by the signal. When
this happens we just return an empty Optional.
The mainloop now checks to see if a resize has been requested by
checking the flag, and if it has it performs a resize.
init() now just calls resize() since the required logic is the same.
Setters for m_filename and m_prompt are removed because these are now
just initialized by the constructor, as they never change for the life
of the program.

This commit makes the Shell check for errors after a node is run(), and
prevents further execution by unwinding until the error is cleared.
Fixes #10649.

We defined it in `stdlib.h` but forgot to implement it.

Save and restore XMM registers so userspace programs don't
randomly lose values from calls. This fixes a crash in ScummVM.

Focus the next tab after closing the currently active tab.
If the tab being closed is the last one then the new last
tab is active.

DateTime::create() and subsequently DateTime::set_time() uses mktime()
internally to ensure out-of-range input values still result in a valid
date (Jan 32 -> Feb 1 etc.).
This however also means that the input is treated as local time, and
then shifted to UTC accordingly for the returned time_t - it is however
already in UTC in this case! The temporary solution is simply to set the
"TZ" environment variable to "UTC" and back after create(). The proper
solution is probably to have better timezone support in Core::DateTime.
This should only affect Lagom, as serenity itself has no timezone
support yet and always assumes UTC.
|
|
Just like in the previous commit, the day value of Core::DateTime is
one-based, not zero based.
Noticed while implementing a new Temporal function, this likely would've
been caught earlier if we'd also use it for the Date API (we don't).
