This will generate absolute paths lexically rather than through a call
to realpath. The motivation for this is to generate absolute paths for
non-existent files in unveil calls, as realpath will not work if the
file does not exist.
LibCore::Account::generate_passwd_file should follow
generate_shadow_file by conditionally checking for the username.
Previously, usermod's set_uid changes would not reflect in the updated
passwd file as m_uid had already been changed to the updated value.
We previously stored the entire ASTNode vector in each parser state,
and this vector was copied whenever a state was loaded or saved.
We don't actually need to store the whole nodes list in each state
because a new state can only add new nodes to this list, and won't
mutate existing nodes.
It would suffice to only hold a vector of the nodes that were created
while parsing in the current state to keep a reference to them.
This reduces the time it takes on my machine for the c++ language
server to handle a file that #includes <LibGUI/Widget.h> from ~4sec to
~0.7sec.
There's no need to store parser error messages for states with
depth > 0, as they will eventually be popped from the states stack and
their error messages will never be displayed to the user.
Profiling shows that this change reduces the % of backtraces that
contain the store_state & load_state functions from ~95% to ~70%.
Empirically this change reduces the time it takes on my machine for the
c++ language server to handle a file that #includes <LibGUI/Widget.h>
from ~14sec to ~4sec.
This fixes a rather frustrating issue during saving a file,
when clicking on a folder (to change the path of saved file)
caused the filename to disappear from the text box.
This is required to make SSE instructions work when building with
Clang. Apparently Clang uses SSE instructions where GCC didn't so
we didn't previously run into this problem.
It's a single expression, no do/while needed. This makes assert() work
with the comma operator (assert(foo), assert(bar), assert(baz)).
Found because exactly this is being used somewhere in the guts of LLVM.
This fixes an crash caused by using the type from
FlacSubframeHeader::order (unsigned 8-bit), which after overflowing
the integer, converting it back to u32, and decrementing by one
resulted in accessing an array waaay out of bounds.
This is Abstract Operation is required for the majority of
InstantConstructor's and InstantPrototype's methods.
The implementation is not entirely complete, (specifically 2 of the
underlying required abstract operations, ParseTemporalTimeZoneString
and ParseISODateTime are missing the required lexing, and as such are
TODO()-ed) but the majority of it is done.
This is an AK::GenericLexer that exposes helper methods for parsing
date and time related literals (years, months, days, hours, minutes,
seconds, fractional seconds & more)
Perform signed integer shifts, addition, subtraction, and rotations
using their corresponding unsigned type. Additionally, mod the right
hand side of shifts and rotations by the bit width of the integer per
the spec. This seems strange, but the spec is clear on the desired
wrapping behavior of arithmetic operations.
macOS's C library is not a good neighbor and doesn't ensure that
the entry in struct hostent's h_addr_list are aligned properly for
a char const*. In Socket::connect, use ByteReader instead of a c-style
cast to work around this possible misalignment.
Before this change, parent widgets such as Buttons or Labels
were stealing drop events their parents.
I noticed it during drag-n-dropping files into visualization widgets
in Sound Player (which takes practically the entire application size
and gave impression that drop events weren't supported in the app
at all).
Calling is_valid_escape_sequence() with no arguments hides what it
is operating on, so I have removed that, so that you must explicitly
tell it what you are testing.
The call from consume_a_token() was using the wrong tokens, so it
returned false incorrectly. This was resulting in corrupted output
when faced with this code from Acid2. (Abbreviated)
```css
.parser { error: \}; }
.parser { }
```
