Reading from /proc/pci assumes we have PCI enabled and also enumerated.
However, if PCI is disabled for some reason, we can't allow the user to
read from it as there's no valuable data we can supply.
To declare that we don't have a PCI bus in the system we do two things:
1. Probe IO ports before enabling access -
In case we are using the QEMU ISA-PC machine type, IO probing results in
floating bus condition (returning 0xFF values), thus, we know we don't
have PCI bus on the system.
2. Allow the user to specify to not use the PCI bus at all in the kernel
commandline.
This change allow the user to request the kernel to not use any PCI
resources/devices at all.
Also, don't try to initialize devices that rely on PCI if disabled.
There are two new sets of messages for the new application-dependent
main states of CatDog. With the current Array-based system, all message
collections must have the same number of messages, but that's not a
problem.
These two new main states are determined by looking at the programs the
user has open. The artist state, using the new artist catdog, is
triggered by PixelPaint and FontEditor, and the inspector state is
triggered by Inspector, Profiler and SystemMonitor. This requires CatDog
to unveil /proc/all, and, for some reason, /etc/passwd.
CatDog's state was previously handled by a bunch of booleans that all
needed to be in sync pretty accurately, but some of these are exclusive
(like alerted and sleeping). This commit introduces a simple enum for
the main states of CatDog which exclude the roaming and direction
states. The main state determines the standing image of CatDog and will
have further effects in the future.
Use the ErrorOr pattern with the Core::System wrappers to propagate more
errors from the TerminalWrapper.
The run_command method, when called with WaitForExit::Yes now returns an
error on command failure.
I also added a common interface with StringView compatible parameters:
int serenity_setenv(const char*, ssize_t, const char*, ssize_t, int)
This function is called by both C and C++ API for setenv().
In the Keymap Settings dialog, a check was missing when the Keymap
selection dialog was cancelled.
Not checking the return value causes an empty string to be added to
the keymap list.
We were mixing up the "name character" and "name start character"
validation checks. Also, we were not checking the first character after
a colon against the "name start character" set.
I was wrong in 56df05ae44, there are
situations where floating children should not affect the auto height of
their parent.
It turns out we were using the "height:auto for BFC roots" algorithm for
all height:auto blocks. This patch fixes that by splitting it into two
separate functions, and implementing most of the two different variants.
Note that we don't support vertical margin collapsing here yet.
Thanks to Tim for noticing the error! :^)
This allows us to submit forms from <button> elements and not just
<input type="submit">
This allows Discord to progress past the username registration :^)
This makes it available for all form associated elements and not just
select and input elements. It also makes it more spec compliant,
especially around the form attribute.
The main thing missing is re-associating form elements with a form
attribute when the form attribute changes or an element with an ID
is inserted/removed or has its ID changed.
A top level browsing context is a browsing context with no parent
browsing context.
However, we considered a top level browsing context to be a browsing
context with no associated browsing context container.
