This subtraction is necessary to ensure that the section has the correct
address. Also, without this change, the Kernel ELF binary would explode
in size. This was forgotten in a0dd6ec6b1.
The information the user is most interested in is usually in the center,
so we should start loading tiles from the center and move outwards.
Since tiles are loaded in draw order, simply drawing them in this order
achieves the desired effect. The current center-outwards loading
algorithm is a basic spiral algorithm, but others may be evaluated
later.
- Convert to FlatPtr instead of doing pointer arithmetic on a too-large
pointer type in find_min_and_max_block_addresses(). This makes the
range more accurate.
- Untag possible cell pointers in add_possible_value() before doing the
rejection. Otherwise we end up rejecting most pointers since the tags
sit in the highest bits!
This fixes a crash when running the Speedometer benchmark.
Just using Vector::resize() meant that we allocated exact capacity
instead of leaving padding at the end. This patch adds a call to
grow_capacity() before resize(), which ensures that we grow with the
usual extra padding.
The bots complain that `forward()` could be either from libc++'s
include/c++/v1/__utility/forward.h or from AK/StdLibExtras.h.
I don't see this locally, but Ladybird also defined AK_DONT_REPLACE_STD,
so let's see if this does the trick.
Use `Meta/serenity.sh build lagom MacPDF` to build, and either of
`open Build/lagom/bin/MacPDF.app` or
`Build/lagom/bin/MacPDF.app/Contents/MacOS/MacPDF` to run.
Xcode used to insert a bunch of things to Info.plist. Now it can
no longer do that, so manually put them there
1. main.m is now main.mm
2. MainMenu.xib is now no longer in a Base.lproj subfolder
3. Remove SerenityPDF.entitlements since it won't be used in our CMake
build
xib changes:
* Add a "Go" toplevel submenu
* Put a "Go to Page..." menu item in it
* Add showGoToPageDialog: to first responder
* Bind action of new menu item to that
The dialog is just a janky NSAlert for now.
This is a bit janky for several reasons:
* `initialize` is now no longer called on a bg thread
* sheet UI is janky both visually and from an implementation PoV
But hey, it works for now.
This works great when quitting and reopening the app,
but when closing a window and the reopening from Recent Files,
the current page isn't restored. In Preview.app, it is.
In the end, apparently I had "Close windows when quitting an
application" enabled in Desktop & Dock in System Settings. With that
turned off, it just worked (...but I still need to serialize the current
page in the view).
Even with it turned off, cmd-opt-q would "Quit and Keep Windows",
so I could've also used that for testing.
Automatic termination means that the app no longer shows up as
opened in the doc when the last Window is closed, but it's actually
still running and opens immediately when clicked again.
Sudden termination means that the app can close quickly on logout.
I think it means the runtime just calls _exit() and assumes all
data is saved continuously.
This change adds a check to discard pointers that are lower than the
minimum address of all allocated blocks or higher than the maximum
address of all blocks. By doing this we avoid executing plenty of set()
operations on the HashMap in the add_possible_value().
With this change gather_conservative_roots() run 10x times faster in
Speedometer React-Redux-TodoMVC test.
This field is in a packed struct, which makes it possibly misaligned.
This knowledge is lost when invoking `dbgln` triggering an unaligned
access to it, aka UB. By explicitely copying it we avoid this issue.
Print out the value of each property in the computed-style of the body
element. This is by no means a thorough test that we're serializing
every property's value correctly in every configuration, (and in fact,
some are definitely wrong,) but it does give us a nice baseline.
