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. :^)

Now we actually check if the Mouse packet relative flag is enabled or
not.
In addition to that, we have debug messages for mouse point changes.

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.

Fixes #816.

This commit adds vertical wrap to menus. The first item is focused if
Key_Down is pressed on the last item and the last item is focused if
Key_up is pressed on the first item.

We now keep DNS answers around in a cache for TTL seconds after getting
them the first time. The cache is capped at 256 responses for now.
Suggested by @zecke in #10.

This makes it more obvious that these mappings come from /etc/hosts.

LibCore's UDP socket is a bit more comfortable to work with. :^)

Apparently some authoritative servers don't handle 0x20 randomization
well and may send EREFUSED. Retry with randomization turned off then.

More work towards #10.

To protect against DNS spoof attacks, we now check that the questions
in incoming responses match the questions in the request we sent out.
Suggested by @zecke in #10.
|
|
This adds a bit of extra entropy to DNS requests, making it harder to
spoof a valid response.
Suggested by @zecke in #10.

- Break out request building into a DNSRequest class.
- Break out response parsing into a DNSResponse class.
A DNSRequest contains one or more DNSQuestion objects.
A DNSResponse contains all the DNSQuestions asked, and a DNSAnswer
object for each answer.

While one window is blocked by another modal one, just ignore events on
the window frame, and also ignore set_minimized() and set_maximized().
The only thing you're allowed to do with a blocked window is moving it.
Fixes #1111.

WSWindow now detaches from WSClientConnection when being destroyed.
Because of this, we can no longer rely on WSWindow::client() to tell
us whether a window is internal to WindowServer or not. So instead we
now have WSWindow::is_internal() which checks for client_id == -1.
Note that WSWindow now also gets a copy of its client_id when
constructed, since we can no longer rely on client() being valid after
destruction has started.
This allows various automatic mechanisms (e.g what happens in response
to window removal) to skip over windows that are being destroyed.
Fixes #387.
|
|
If something goes wrong when trying to message a windowing client,
we now tear it down *on next event loop* instead of immediately.
This avoids having to deal with disconnected windows suddenly
disappearing from window lists while looping over them.

This changes copyright holder to myself for the source code files that I've
created or have (almost) completely rewritten. Not included are the files
that were significantly changed by others even though it was me who originally
created them (think HtmlView), or the many other files I've contributed code to.
|
|
Once LookupServer is initialized it should never need
access to any any paths for the lifetime of the process.
Lock the veil post initialization.
|
|
Once the event loop is constructed, we will have opened /dev/audio for
output and no more filesystem lookups need to happen.
|
|
Without this, we can't start programs via the system menu. This begs
the question: should WindowServer really be allowed to fork and exec
in the first place?
|
|
WindowServer needs persistent access to a few things:
- /res (for themes, fonts, cursors, apps, wallpapers, etc.)
- /etc/passwd (for username lookup, not sure this is actually needed..)
- /home/anon/WindowManager.ini (FIXME: this should not be hard-coded..)
These things are unveiled temporarily, and then dropped:
- /tmp (for setting up sockets)
- /dev (for opening input and framebuffer devices)
This leaves WindowServer running with a very limited view of the file
system, how neat is that!

A mouse move event needs to do a bit more work than what a mouse wheel event
does. Mouse wheel just needs to update the hovered item, and update for a new
hovered item. This also stops us from calling redraw() twice on a wheel event.
|
|
While I really enjoyed having an infinite cycle when I implemented menu
keys (and seeing it wizz around and around :D), menu key movement should
be consistent between menus - and an inifinite cycle does not make much
sense for a scrollable menu.
|
|
Menus now have a scroll offset (index based, not pixel based) which is
controlled either with the mouse wheel or with the up/down arrow keys.
This finally allows us to browse all of the fonts that @xTibor has made
avilable through his serenity-fontdev project:
https://github.com/xTibor/serenity-fontdev
I'm not completely sure about the up/down arrows. They feel like maybe
they occupy a bit too much vertical space.
Also FIXME: this mechanism probably won't look completely right for
menus that have separators in them.
Fixes #1043.

Use an imaginary triangle between the top and bottom of the submenu of a
hovered item to determine whether the mouse is moving towards the
submenu. If it is, we do not update the hovered item. This allows the
submenu to stay open, making for much easier menu navigation.
Closes #1094

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.

Tracking the hovered menu item independently from the index of the
currently hovered item is error prone and bad code. Simplify WSMenu by
only tracking the index of the currently hovered item.
Fixes #1092

We were swallowing the keyevent on a Logo key down even if we were not
opening the logo. This is incorrect, and was preventing the
windowswitcher from closing.
We also make the logo button toggle the system menu, as this behaviour
is closer to how you would normally expect this button to work.
Closes #1090

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.

Longer-term we should come up with a design where WindowServer doesn't
have to decode untrusted image files.
|
|
|
|
SystemServer now pledges "tty" since it's used when spawning services.
|
|
If there is a current menu, we now redirect all key events from window
manager to the menu manager. This allows us to properly navigate a menu
even when there is a current menu open.
Menu key navigation is now a lot more pleasant to use :^)
The action of pressing escape to close a menu has also been moved to its
proper home in menu manager in this commit.
|
|
set_current_menu() was indiscriminately closing all menus when the
current menu is not a submenu. We should only close menus not in lineage
to the one being closed.
|
|
We were forgetting to update the current menu when switching to a new
item.
We also rename the function from implying that only a redraw is
happening, as is actually not the case. It is now more correctly named:
update_for_new_hovered_item()
|
|
It was still possible to pop up the system menu by letting go of the
mouse button before letting go of the Logo key. This patch fixes that.
|
|
WindowServer becomes the only user.
|
|
|
|
Update various places that now need wider promises as they are not
reset by fork() anymore.
