Changing the statusbar appearance when overriding text makes it less
confusing as it's supposed to be something temporary, e.g. only when
hovering over a toolbar or menu item.
This behavior is present on old Windows systems, although things work
slightly differently there (where only the overridden text is displayed
rather than all the segments).

This allows you to serialize a <canvas> element's bitmap into a
data: URI. Pretty neat! :^)
|
|
This is still far from ideal, but let's at least make it take a
Gfx::Bitmap const&.

When node is NULL and AI_PASSIVE is specified we are supposed to use
the "any" address, otherwise we should use the loopback address.

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.

Shared objects without a text segment are perfectly OK. For
example libicudata.so has only data segments:

This commit re-adds the functionality of the start menu appearing when
the super key is pressed
|
|
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 :)

Expose the new `profiling_free_buffer` syscall to user space.
|

Often you want to enable and then disable profiling after a period of time.
To make this slightly more ergonomic, add an option to wait for user
input after enabling profiling, this will disable profiling on exit
after the key press.

The stubs are necessary to make the xz port properly detect pthread
support. The two functions are only used in the configure script and
nowhere else.

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.

Fixes #6472.

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).

Having unresolved weak symbols is allowed and we should initialize
them to zero.
|
|
This way we get better error messages for unresolved symbols because
the caller logs the file and symbol names.

The order of arguments seemed be confusing ArgsParser.
Fixes #6467.
|
|
e.g. `test ! = !`.
Fixes #6465.

This library currently contains a basic WebSocket client that can
handle both standard TCP websockets and TLS websockets.

The API existed for add_positional_argument, but not for named arguments.

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.
|
|
The count is always non-negative

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)
1305693298.670892

Since font type changes also change the amount of glyphs in a font, the
glyph map has to be re-rendered to properly showcase the change.

We can now add a watchpoint to a variable by right clicking on it
in the variable view, and selecting add watchpoint. To remove a
watchpoint, the exact same action is repeated, except it will now say
remove watchpoint.
|
|
Previously, if the running debugger asked for HackStudio to open
an invalid file, it would crash trying to switch to it. Now it will
just continue without switching the editor.
|
|
Now we can set hardware watchpoints for our variables! :^)
These watchpoints will be automatically removed when
they go out of scope.

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.
