When building with ccache these ports failed to build because
CC contains more than one word.
The ncurses port also doesn't like how ccache preprocesses
files. This patch fixes that.
This port was still using the upstream's master branch as opposed to
a fixed git commit.
Also, now that SDL2 is installed into /usr/local the build failed.
I have also removed an obsolete patch because we're now linking
against shared libraries for SDL2 and those already have appropriate
library dependencies.
We intentionally skimp out on checking isatty() before them to cut down
on syscalls, so we should also accept the errors and just let them be.
Closes#6471.
As well as correctly calculating the height of TableRowBox, this change
calculates the heights of TableRowGroupBoxs also.
As before, this does not correctly take into consideration the 'height'
attribute.
Now the horizontal layout is approximately correct for the
TableRowGroupBoxs we can now see that the `layout_row` method will need
updating to correctly calculate cell width across all rows, not just the
current TableRowGroupBox.
As the spec for the table fixup algorythm says:
> Treat table-row-groups in this spec also encompass the specialized
> table-header-groups and table-footer-groups.
The calculation for TLS relocations was incorrect which would
result in overlapping TLS variables when more than one shared
object used TLS variables.
This bug can be reproduced with a shared library and a program
like this:
$ cat tlstest.c
#include <string.h>
__thread char tls_val[1024];
void set_val() { memset(tls_val, 0, sizeof(tls_val)); }
$ gcc -g -shared -o usr/lib/libtlstest.so tlstest.c
$ cat test.c
void set_val();
int main() { set_val(); }
$ gcc -g -o tls test.c -ltlstest
Due to the way the TLS relocations are done this program would
clobber libc's TLS variables (e.g. errno).
Problem:
- Newer versions of clang (ToT) have a similar `-Wliteral-suffix`
warning as GCC. A previous commit enabled it for all compilers. This
needs to be silenced for the entire build, but it currently only is
silenced for some directories.
Solution:
- Move the `-Wno-literal-suffix` option up in the CMakeLists.txt so
that it gets applied everywhere.
This fixed-width font had some garbage per glyph width values, which
while previously was ok, they now had to be correctly set to indicate
glyph presence.
This uses the per glyph width to determine if the glyph is actually
present in the font, and not just inside the range the font can covers
This means that characters that are in the font's range but that are
missing a glyph will show up as the missing character glyph instead of
being invisible.
This replaces the glyph width spinbox in the font editor with a
checkbox when editing fixed width fonts that indicates if the
currently selected character's glyph is present in the edited font
(For variable width fonts a non zero width implies presence)
This commit also changes the background color of glyphs in the glyph
map based on the presence of each specific glyph in the font.
Since we were always saving the glyph widths array to the font file, we
now also always load it, even on (which also simplifies the logic a bit)
fixed width fonts. We also set it initially to 0 instead of the default
fixed width, which allows us to use it to check for glyph presence in
both fixed width and variable width fonts.
Problem:
- Post-increment of loop index.
- `const` variables are not marked `const`.
- Incorrect type for loop index.
Solution:
- Pre-increment loop index.
- Mark all possible variables `const`.
- Corret type for loop index.
Problem:
- Hex digit decoding is not `constexpr`, but can be.
Solution:
- Move the body of the function to the header and decorate with
`constexpr`.
- Provide tests for run-time and compile-time evaluation.
Problem:
- There are redundant options being set for some directories.
- Clang ToT fails to compile the project.
Solution:
- Remove redundancies.
- Fix clang error list.
This command line flag can be used to disable VirtIO support on
certain configurations (native windows) where interfacing with
virtio devices can cause qemu to freeze.
Some of the expected values in test-math were wrong, which caused some
tests to fail.
The updated values were generated by Python's math library, and rounded
to 6 decimals places:
>>> import math
>>> round(math.exp(20.99), 6)

Pressing this combo will dump a list of all threads and their state
to the debug console.
This might be useful to figure out why the system is not responding.
