Instruction::to_string used to copy a string literal into a String,
and then the String into a StringBuilder. Copy it to the StringBuilder
directly.
No measurable performance benefit, but it's also less code.
This lets disasm output contain the symbol names of call and jump
destinations:
8048111: e8 88 38 01 00 call 805b99e <__cxa_atexit>
...
8048150: 74 15 je 8048167 <_start+0x4c>
The latter (the symbol of the current function with an offset) is
arguably more distracting than useful because you usually want to look
at the instruction at the absolute offset in this case, but the former
is very nice to have.
For reasons I do not understand, this cuts the time to run
`disasm /bin/id` in half, from ~1s to ~0.5s.
From a layering perspective, it's maybe a bit surprising that the
X86::SymbolProvider implementation also lives in LibX86, but since
everything depends on LibELF via LibC, and since all current
LibX86-based disassemblers want to use ELFSymbolProvider, it makes
some amount of sense to put it there.
If the process table grows or shrinks, we need to invalidate all the
ProcessModel indexes. This is not great, but it's the most precise
invalidation we can do at the moment.
Instead of SortingProxyModel having a column+order, we move that state
to AbstractView. When you click on a column header, the view tells the
model to resort the relevant column with the new order.
This is implemented in SortingProxyModel by simply walking all the
reified source/proxy mappings and resorting their row indexes.
This removes one major source of confusion in DirectoryView. It's still
weird that we mix sorting model indexes with filesystem model indexes
a bit willy-nilly but we'll improve that separately.
We now create multiple levels of internal mappings between source
and proxy indexes, to support tree models.
This breaks selection update after resort, which we'll have to
deal with somehow.
This patch adds SortingProxyModel::less_than(ModelIndex, ModelIndex)
which is now used to implement the sort order. This allows you to
subclass SortingProxyModel if you want to tweak how sorting works.
Get rid of the awkward case sensitivity logic in SortingProxyModel
since that can now be done outside. Turns out nobody was actually
using it anyway, but it seems like something we will want to do
in the future someday.
Windows have an initial off-screen rect, so when a dialog is created and
shown before its parent window, in which it is centered, it would be
invisible to the user.
Fixes#3172.
If they use up so much stack space, contain (sometimes several) loops, and take
a noticable amount of time anyway, then 'inline' is probably going to be ignored
by the compiler anyway.
This changes the graph caption from KB to KiB, but it keeps just "K"
instead of "KiB" for all the numbers in columns in the table, since "K"
is fairly well-established as abbreviation of "KiB" (the SI prefix is
lower-case), and space is at a premium here.
Windows uses "KB", "MB", "GB" as powers of two.
macOS uses "kB", "MB", "GB" as powers of ten.
"k", "M", "G" are standard SI prefixes that normally refer to powers of
ten.
The IEC introduced "KiB", "MiB", "GiB" to unambiguously refer to
powers of two. It admittedly hasn't caught on that much, but it
does have the advantage that it's unabigious what it means.
So let's use it for user-visible sizes in SerenityOS.
(Linux does all of the above in different places, depending on app and
toolkit.)
Let's use the one in AK/NumberFormat.h everywhere.
It has slightly different behavior than some of the copies this
removes, but it's probably nice to have uniform human readable
size outputs across the system.
The SI prefixes "k", "M", "G" mean "10^3", "10^6", "10^9".
The IEC prefixes "Ki", "Mi", "Gi" mean "2^10", "2^20", "2^30".
Let's use the correct name, at least in code.
Only changes the name of the constants, no other behavior change.
I originally defined the bytes() method for the String class, because it
made it obvious that it's a span of bytes instead of span of characters.
This commit makes this more consistent by defining a bytes() method when
the type of the span is known to be u8.
Additionaly, the cast operator to Bytes is overloaded for ByteBuffer and
such.
