In the fresh and minimal installations dev package are often
stripped. This commit will install the libssl dev packages
required in `Utilities/cmcurl/CMakeLists.txt:608`.
To further protect all virtual memory regions of the loaded libraries,
don't allow to mutate these regions both in changing their annotations
nor the protection bits.
We add this basic functionality to the Kernel so Userspace can request a
particular virtual memory mapping to be immutable. This will be useful
later on in the DynamicLoader code.
The annotation of a particular Kernel Region as immutable implies that
the following restrictions apply, so these features are prohibited:
- Changing the region's protection bits
- Unmapping the region
- Annotating the region with other virtual memory flags
- Applying further memory advises on the region
- Changing the region name
- Re-mapping the region
This syscall will be used later on to ensure we can declare virtual
memory mappings as immutable (which means that the underlying Region is
basically immutable for both future annotations or changing the
protection bits of it).
As is, we never *deallocate* them, so we will run out eventually.
Creating a context, or allocating a context ID, now returns ErrorOr if
there are no available free context IDs.
`number_of_fixmes--;` :^)
This patch adds a new add_tab() function in GUI::SettingsWindow that
takes an already created NonnullRefPtr<Tab> object. This allows us to
handle errors while creating the Tab object and then pass it to this
function to actually add the object to the SettingsWindow.
This patch allows returning an `Error` from the `on_complete` callback
in `BackgroundAction`.
It also adds a custom callback to manage errors returned during its
execution.
This moves the actual launching of browser windows to the WebDriver main
file. This will allow Ladybird to specify its own callback and re-use
Serenity's Session class.
When parsing a code block not in a section (in a file without a
heading), the parser would initialize the code block with an
uninitialized (invalid) value for current_section. Accessing this value
would later cause a segmentation fault in render_to_terminal.
This class is a smart pointer that let you provide a custom deleter to
free the pointer.
It is quite primitive compared to other smart pointers but can still be
useful when interacting with C types that provides a custom `free()`
function.
This is to differentiate between the upcoming `AllocatingMemoryStream`,
which automatically allocates memory as needed instead of operating on a
static memory area.
Default-constructing the m_value Completion made it have an undefined
JS value when not overridden in a constructor, such as the conditional
initialization in Optional(Optional<JS::Completion> const&).
