This patch adds a PreviewMode enum with the following values:
- None
- Markdown
- HTML
This makes it a bit more logical to implement exclusive behavior.
This function relies on visible_content_rect() which could previously
return rectangles with negative size. This was causing TableViews to
scroll down a little bit when assigning a model to them.
Also tweak the logic so we scroll a 0x0 rect into view, giving a
slightly nicer final position.
During app teardown, the Application object may be destroyed before
something else, and so having Application::the() return a reference was
obscuring the truth about its lifetime.
This patch makes the API more honest by returning a pointer. While
this makes call sites look a bit more sketchy, do note that the global
Application pointer only becomes null during app teardown.
To make the plain text we copy out from LibWeb look at least somewhat
like its original form, let's insert newlines at <br> elements and when
we exit a block-level element.
This is far from perfect, but seems to work pretty okay.
This works by finding the very first and very last LayoutText nodes
in the layout tree and then setting the selection bounds to those two
nodes. For some reason it gets glitchy if we set the very first and
very last *LayoutNode* as the selection bounds, but I didn't feel like
investigating that too closely right now.
There isn't an easy way to retreive all register contents anymore,
so remove this functionality. We do have the ability to trace
processes, so it shouldn't really be needed anymore.
If we're trying to walk the stack for another thread, we can
no longer retreive the EBP register from Thread::m_tss. Instead,
we need to look at the top of the kernel stack, because all threads
not currently running were last in kernel mode. Context switches
now always trigger a brief switch to kernel mode, and Thread::m_tss
only is used to save ESP and EIP.
Fixes#2678
When delivering urgent signals to the current thread
we need to check if we should be unblocked, and if not
we need to yield to another process.
We also need to make sure that we suppress context switches
during Process::exec() so that we don't clobber the registers
that it sets up (eip mainly) by a context switch. To be able
to do that we add the concept of a critical section, which are
similar to Process::m_in_irq but different in that they can be
requested at any time. Calls to Scheduler::yield and
Scheduler::donate_to will return instantly without triggering
a context switch, but the processor will then asynchronously
trigger a context switch once the critical section is left.
Prior to this, we wrote to the log every time the << operator
was used, which meant that only these parts of the log statement
were serialized. If the thread was preempted, or especially with
multiple CPUs the debug output was hard to decipher. Instead, we
buffer up the log statements. To avoid allocations we'll attempt
to use stack space, which covers most log statements.
- Use emojis instead of the pass/fail text
- Fix the new version of the script to run inside Serenity
- Don't print erroneous output after 'Output:'; start on a newline
instead
- Skip 'run-tests.sh' while testing
