The shared library libicudata.so has a DT_SYMBOLIC entry:
Dynamic Section:
NEEDED libgcc_s.so
SONAME libicudata.so.69
SYMBOLIC 0x00000000
HASH 0x00000094
STRTAB 0x000000c8
SYMTAB 0x000000a8
STRSZ 0x0000002a
SYMENT 0x00000010
According to the ELF spec DT_SYMBOLIC has no special meaning
for the dynamic loader.
This commit adds an event called WM_SuperKeyPressed which is sent to all
windows via WindowManagerServerConnection.
The event is fired from WindowManager when the super key is pressed,
which is the windows key on most keyboards :)
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).
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.
This adds PT_PEEKDEBUG and PT_POKEDEBUG to allow for reading/writing
the debug registers, and updates the Kernel's debug handler to read the
new information from the debug status register.
The vsscanf library function lets the user skip assigning
parsed values to the arguments, e.g. with %*c - even though
a character is scanned it is not assigned to one of the
arguments.
The figlet port uses this. With this patch the port is actually
usable.
