URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.

Set preferred height instead of fixed height to allow the splitter to
move.
The splitter respects set_fixed_height() after a808cfa7 "LibGUI+
Applications: Govern Splitter resizing by opportunistic growth", and
that caused the splitter in Profiler to stop working.
The flame graph view used to draw only so much of the graph that could
be displayed. Change to draw the whole graph, and add a scrollbar.
Does some tricks with the scrolling to keep the bottom of the graph
fixed when resizing or double-clicking, since it works better then.
Layout cleared the list of bars in the flame graph, but didn't clear the
reference m_hovered_bar. This could cause a crash in mousedown_event()
when clicking twice: the first click caused layout, the second used
the old reference.
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
This way, we can change the constant in one place. Note that this
requires the use of nested format strings, which is slightly ugly but
safe to do in this instance.
This constant is currently 3 but can be changed easily or integrated
into a user setting. Note that the results are not ideal because during
pretty-printing we're not using any nice rounding rules, so many
percentage values will actually appear as 0.399999 even though they were
rounded to three digits.
This commit adds "Filesystem Events" View to the Profiler. This tab
will present combined information for recorded Filesystem events.
Currently only accumulated count and duration is presented.
Duration amount currently only shows events that took over 1ms,
which means that in most cases 0 is show.
This adds a new view mode to profiler which displays source lines and
samples that occured at those lines. This view can be opened via the
menu or by pressing CTRL-S.
It does this by mapping file names from DWARF to "/usr/src/serenity/..."
i.e. source code should be copied to /usr/src/serenity/Userland and
/usr/src/serenity/Kernel to be visible in this mode.
Currently *all* files contributing to the selected function are loaded
completely which could be a lot of data when dealing with lots of
inlined code.
No need to copy and move them around, just to pass them as a
`String const&` to the constructor.
We still end up copying it to a normal String in the end though...
Also add slightly richer parse errors now that we can include a string
literal with returned errors.
This will allow us to use TRY() when working with JSON data.
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.
