This removes some hard references to the toolchain, some unnecessary
uses of an external install command, and disables a -Werror flag (for
the time being) - only if run inside serenity.
With this, we can build and link the kernel :^)
This required a bit of rearchitecture, as pthread_atfork() required a
mutex, and duplicating a mutex impl for it was silly.
As such, this patch moves some standalone bits of pthread into LibC and
uses those to implement atfork().
It should be noted that for programs that don't use atfork(), this
mechanism only costs two atomic loads (as opposed to the normal mutex
lock+unlock) :^)
This implementation is pretty damn dumb, and probably has more bugs than
features.
But for the time being, it seems to work. however, we should definitely
replace it with a good implementation sometime very soon :^)
This adds a new structure 'Typeface' to the FontDatabase that
represents all fonts of the same family and variant.
It can contain a list of BitmapFonts with varying size but of
the same family and weight or a pointer to a single TTF font
for all sizes of this Typeface.
`length` is only the (trimmed) size of the word vector, so we have to
multiply it with the size of each element to ensure all bytes are
compared.
Fixes#5335.
I noticed that programs running in the terminal had an open file
descriptor for the system theme buffer, inherited from the Terminal.
Let's be nice and always mark incoming fds with FD_CLOEXEC.
In some circumstances (like template selection dialogs,) displaying as much
item label as possible, on all items, may be desired.
The default setting is 'false', which matches the default behaviour from before;
only wrapping on hover or selection.
Allocate GC heap blocks with mmap(MAP_RANDOMIZED) for ASLR.
This may very well be too aggressive in terms of fragmentation, and we
can figure out ways to scale that back once it becomes a big problem.
For now, this makes the GC heap a lot less predictable for an attacker.
This replaces the manual watch_file and Notifier handling with the new
Core::FileWatcher wrapper, which reduces the manual handling and makes
the code easier to reason about :^)
This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.
Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.
