When pressing the Left arrow key, we now travel to the parent_index()
of the currently selected index. Our implementation of parent_index()
was always returning an index with column 0, instead of using the
same column as the current index.
This prevented the selected item from looking selected.
This makes unknown addresses accumulate their children together in the
treeview, which turns out to be a bit more useful than having hundreds
of unique garbage addresses each with their own subtree.
ProfileViewer will now attempt to open /boot/kernel and use that to
symbolicate kernel addresses (anything above the 3GB mark.)
In other words, if you run ProfileViewer as root, on a profile that
was generated by root, you can now see kernel functions properly
as well. This is not available to non-privileged users.
This shaves ~5 seconds off of a full build, not too bad. Also it just
seems nicer to push this logic out to classes. It could be better but
it's a start. :^)
Compiling anything that includes generated IPC messages is painfully
slow at the moment. This moves the encoding helpers out of line, which
helps a bit. Doing the same for decoding will help more.
This patch introduces the GUI::SyntaxHighlighter class, which can be
attached to a GUI::TextEditor to provide syntax highlighting.
The C++ syntax highlighting from HackStudio becomes a new class called
GUI::CppSyntaxHighlighter. This will make it possible to get C++ syntax
highlighting in any app that uses a GUI::TextEditor. :^)
Sidenote: It does feel a bit weird having a C++ lexer in a GUI toolkit
library, and we'll probably end up moving this out to a separate place
as this functionality grows larger.
I started adding things to a Draw namespace, but it somehow felt really
wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename
the library to LibGfx. :^)
This makes getting a pseudoterminal pair a little bit more portable.
Note that grantpt() and unlockpt() are currently no-ops, since we've
already granted the pseudoterminal slave to the calling user.
We also accept O_CLOEXEC to posix_openpt(), unlike some systems. :^)
Since BufferStream is about creating specific binary stream formats,
let's not have a flaky type like size_t in there. Instead, clients of
BufferStream can cast their size_t to the binary size they want to use.
Account for this in IPCCompiler by making String lengths always 32-bit.
For memory profiles, we now keep track of which allocations are still
live at the end of the selected timeline range and only show those.
This is really cool, I have to admit. :^)
"perfcore" is the file that the kernel generates after a process that
was recording performance events has exited.
This patch teaches ProfileViewer how to load (and symbolicate!) those
files so that we can look at them. This will need a bunch more work
to make it truly useful.
I've been wanting to do this for a long time. It's time we start being
consistent about how this stuff works.
The new convention is:
- "LibFoo" is a userspace library that provides the "Foo" namespace.
That's it :^) This was pretty tedious to convert and I didn't even
start on LibGUI yet. But it's coming up next.
Technically the bottom 2MB is still identity-mapped for the kernel and
not made available to userspace at all, but for simplicity's sake we
can just ignore that and make "address < 0xc0000000" the canonical
check for user/kernel.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
This patch adds a new "accept" promise that allows you to call accept()
on an already listening socket. This lets programs set up a socket for
for listening and then dropping "inet" and/or "unix" so that only
incoming (and existing) connections are allowed from that point on.
No new outgoing connections or listening server sockets can be created.
In addition to accept() it also allows getsockopt() with SOL_SOCKET
and SO_PEERCRED, which is used to find the PID/UID/GID of the socket
peer. This is used by our IPC library when creating shared buffers that
should only be accessible to a specific peer process.
This allows us to drop "unix" in WindowServer and LookupServer. :^)
It also makes the debugging/introspection RPC sockets in CEventLoop
based programs work again.
Launching from the terminal inherits $PATH which includes
/usr/local/bin, but launching from the system menubar doesn't, so
HackStudio wasn't finding make installed from ports.
