Instead of FileDescriptor branching on the type of File it's wrapping,
add a File::stat() function that can be overridden to provide custom
behavior for the stat syscalls.
This fetches information from /var/run/utmp and shows the interactive
sessions in a little list. More things can be added here to make it
more interesting. :^)
To keep track of ongoing terminal sessions, we now have a sort-of
traditional /var/run/utmp file, like other Unix systems.
Unlike other Unix systems however, ours is of course JSON. :^)
The /bin/utmpupdate program is used to update the file, which is
not writable by regular user accounts. This helper program is
set-GID "utmp".
For now, the new DOM::EventDispatcher is very simple, it just iterates
over the set of listeners on an EventTarget and invokes the callbacks
as it goes.
This simplifies EventTarget subclasses since they no longer have to
implement the callback mechanism themselves.
The streaming operator doesn't short-circuit, consider the following
snippet:
void foo(InputStream& stream) {
int a, b;
stream >> a >> b;
}
If the first read fails, the second is called regardless. It should be
well defined what happens in this case: nothing.
I suspected an error in CircularDuplexStream::read(Bytes, size_t). This
does not appear to be the case, this test case is useful regardless.
The following script was used to generate the test:
import gzip
uncompressed = []
for _ in range(0x100):
uncompressed.append(1)
for _ in range(0x7e00):
uncompressed.append(0)
for _ in range(0x100):
uncompressed.append(1)
compressed = gzip.compress(bytes(uncompressed))
compressed = ", ".join(f"0x{byte:02x}" for byte in compressed)
print(f"""\
TEST_CASE(gzip_decompress_repeat_around_buffer)
{{
const u8 compressed[] = {{
{compressed}
}};
u8 uncompressed[0x8011];
Bytes{{ uncompressed, sizeof(uncompressed) }}.fill(0);
uncompressed[0x8000] = 1;
const auto decompressed = Compress::GzipDecompressor::decompress_all({{ compressed, sizeof(compressed) }});
EXPECT(compare({{ uncompressed, sizeof(uncompressed) }}, decompressed.bytes()));
}}
""", end="")
Now that we can copy bitmaps, we need some kind of cap here or memory
usage quickly skyrockets.
This could probably be improved or made adaptive somehow, this is just
a simple hard cap for now.
It seems that new people go to the build instructions from the main
README, don't see Windows and are then stuck.
We do have instructions for Windows, but they aren't noted in the build
instructions, so new people get stuck thinking there's no way to build
on Windows.
Currently, every time the wallpaper picker changes, an additional
attempted file load happens on top of the file load to create the
bitmap. The only values that the wallpaper picker can take on are
filenames that can never be valid when loaded without the /res/wallpaper
prefix. To reduce the amount of log spam and speed up wallpaper picking,
this patch only attempts to load wallpapers with slash-prefixed names,
assumed to be the absolute path to that wallpaper. Additional wallpapers
outside of /res/wallpapers/ should still be accessible with this patch,
and the experience is improved for the more common case of selecting a
built-in wallpaper.
Addresses #3394 which was caused by dereferencing null `test_name`
when no arguments were given to /bin/tt. Additionally, arguments
other than the defined tests now print usage and exit to avoid
running the default test.
Move the basic movement keys (up/down/left/right/home/end/pgup/pgdn)
up to AbstractView::keydown_event() and have it call the virtual
move_cursor() which is then implemented by subclasses.
