These were forgotten in the last LibLine commit, any changes to m_buffer
not going through insert() and remove_at_index() should also be updating
these.
Fixes#5440.
This is a new promise that guards access to mmap() with MAP_FIXED.
Fixed-address mappings are rarely used, but can be useful if you are
trying to groom the process address space for malicious purposes.
None of our programs need this at the moment, as the only user of
MAP_FIXED is DynamicLoader, but the fixed mappings are constructed
before the process has had a chance to pledge anything.
Route the ScrollBar's wheel event to the ScrollableWidget so it can
handle it itself. This allows it to handle it consistently (e.g.
speed) when the cursor is hovering the scroll bars rather than the
widget's contents.
Fixes#5419
We want to make sure these functions actually do get unmapped. If they
were inlined somewhere, the inlined version(s) would remain mapped.
Thanks to "thislooksfun" for the suggestion! :^)
Let's use a stronger type than void* for this since we're talking
specifically about a virtual address and not necessarily a pointer
to something actually in memory (yet).
It was very confusing how these functions used the "undefined" state
of Symbol to signal lookup failure. Let's use Optional<T> to make things
a bit more understandable.
This patchset allows the editor to avoid redrawing the entire line when
the changes cause no unrecoverable style updates, and are at the end of
the line (this applies to most normal typing situations).
Cases that this does not resolve:
- When the cursor is not at the end of the buffer
- When a display refresh changes the styles on the already-drawn parts
of the line
- When the prompt has not yet been drawn, or has somehow changed
Fixes#5296.
Fixes hidable horizontal scrollbars remaining visible even after
collapsing their responsible nodes. Tree column width defaults to
column header width if wider than current content.
This was weird. It turns out these class were using int indexes and
sizes despite being derived from Vector which uses size_t.
Make the universe right again by using size_t here as well.
The C++ LanguageServer can now find the matching declaration for
variable names, function calls, struct/class types and properties.
When clicking on one of the above with Ctrl pressed, HackStudio will
ask the language server to find a matching declaration, and navigate
to the result in the Editor. :^)
