This adds a "settings" option that allows the user to configure the
board size and target tile, and optionally save them to a config file.
Closes#3219.
The constructor with a string argument isn't implemented yet, but
this implements the other variants.
The timestamp constructor doens't handle negative timestamps correctly.
Out-of-bound and invalid arguments aren't handled correctly.
Previously we were putting strings at the bottom of the allocated stack
region, and pointer arrays (argv, env, auxv) at the top. There was no
reason for this other than "it seemed easier to do it that way at the
time I wrote it."
This patch packs the strings and pointer vectors into the same area at
the top of the stack.
This reduces the memory footprint of all programs by 4 KiB. :^)
Previously, the implementation would produce one Vector<u8> which
would contain the whole decompressed data. That can be a lot and
even exhaust memory.
With these changes it is still necessary to store the whole input data
in one piece (I am working on this next,) but the output can be read
block by block. (That's not optimal either because blocks can be
arbitrarily large, but it's good for now.)
This class is similar to BufferStream because it is possible to both
read and write to it. However, it differs in the following ways:
- DuplexMemoryStream keeps a history of 64KiB and discards the rest,
BufferStream always keeps everything around.
- DuplexMemoryStream tracks reading and writing seperately, the
following is valid:
DuplexMemoryStream stream;
stream << 42;
int value;
stream >> value;
For BufferStream it would read:
BufferStream stream;
stream << 42;
int value;
stream.seek(0);
stream >> value;
In the future I would like to replace all usages of BufferStream with
InputMemoryStream, OutputMemoryStream (doesn't exist yet) and
DuplexMemoryStream. For now I just add DuplexMemoryStream though.
Fatal errors can not be handeled and lead to an assertion error when the
stream is destroyed. It makes no sense to delay the assertion failure,
instead of setting m_fatal, an assertion should be done directly.
Two changes were made
1. copy_to() and copy_trimmed_to() now return how many bytes were
copied.
2. The argument was changed to Span<typename RemoveConst<T>::Type>
because the following would not work:
ReadonlyBytes bytes0;
Bytes bytes1;
// Won't work because this calls Span<const u8>::copy_to(Span<u8>)
// but the method was defined as Span<const u8>::copy_to(Span<const u8>)
bytes0.copy_to(bytes1);
Prior to this, no keybinding were installed on the search editor, and so
editing wasn't really possible.
Also fixes <C-r> making infinite search editors.
This does not add any behaviour change to the processes, but it ties a
TTY to an active process group via TIOCSPGRP, and returns the TTY to the
kernel when all processes in the process group die.
Also makes the TTY keep a link to the original controlling process' parent (for
SIGCHLD) instead of the process itself.
urls were previously added to history in the Tab::load()
function, which excluded the setter on window.location.href.
This commit adds all urls to browser history when the page loads,
as long as the load_type is not LoadType::HistoryNavigation.
Closes#3148
This fixes a bunch of unchecked kernel reads and writes, seems like they
would might exploitable :). Write of sockaddr_in size to any address you
please...
Note that the data member is of type ImmutableBufferArgument, which has
no Userspace<T> usage. I left it alone for now, to be fixed in a future
change holistically for all usages.
We need to update all button rectangles when the layout changed.
We also need to clear the taskbar button rectangle when we
remove a modal window button, so that WindowServer uses the
parent's taskbar button rectangle for the minimize animation.
If a modal window is being minimized, it may not have its own
taskbar rectangle. In that case, try finding a parent in the
modal window stack that does have one, and use that for the
animation.
This avoids a call to clone() which would be discarded immediately.
Also, avoid essentially cloning for each hammer rectangle unless
there is actually a need for it.
Unlike DirectoryEntry (which is used when constructing directories),
DirectoryEntryView does not manage storage for file names. Names are
just StringViews.
This is much more suited to the directory traversal API and makes
it easier to implement this in file system classes since they no
longer need to create temporary name copies while traversing.
