If a scrollbar doesn't have a scrubber (because the view it scrolls is
large enough to display all its contents without scrolling), then
it ignores all clicks. We shouldn't draw a hover highlight that suggests
clickability in that case.
This also makes the editor clean as many lines as the searching took,
for instance, in the case of <C-r><C-c>ls<tab>, two lines should be
cleaned, not just one.
Fixes#3413.
g++ seems to generate calls to __cxa_guard_* functions when we use
non-trivial initialization of local statics.
Requiring these symbols breaks some ports since these symbols are
defined in libcstdc++ which we do not link against when building ports.
This commit turns some local statics into global statics in netdb.cpp so
libc wouldn't need these symbols.
Previously, we were including the whole of <getopt.h> in <unistd.h>.
However according to the posix <unistd.h> doesn't have to contain
everything we had in <getopt.h>.
This fixes some symbol collisions that broke the git port.
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()));
}}

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.
This patch adds an optional mode where TextEditor highlights trailing
whitespace characters on each line with a nice reddish dither pattern.
We should probably make this themable and I'm sure it could be nicer
somehow, but this is just a first cut and I do kinda like it. :^)
Looks like an oversight to me - we were not actually setting a new value
for m_array_size, which would cause arrays created with generic storage
to report a .length of 0.
This is already considered in put()/insert()/append_all() but not
set_array_like_size(), which crashed the interpreter with an assertion
when creating an array with more than SPARSE_ARRAY_THRESHOLD (200)
initial elements as the simple storage was being resized beyond its
limit.
Fixes#3382.
