Services can now have their initial working directory
configured via `SystemServer.ini`.
This commit also configures Terminal's working directory
to be /home/anon
SystemServer will now track the number of restart attempts and the
run time of a service, and will also pay attention to its exit code.
If a service exits unsuccessfully and too quickly (in less than a
second), SystemServer will only attempt to restart it twice.
This means that if WindowServer crashes on startup, we will now see
just a few copies of the crash instead of the quickly scrolling log
flashing with colors :^)
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.
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.
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.
We now pick up all the user's extra GIDs from /etc/group and make
sure those are set before exec'ing a service.
This means we finally get to enjoy being in more than one group. :^)
For services explicitly configured as lazy, SystemServer will now listen
on the socket and only spawn the service once a client attempts to connect
to the socket.
SystemServer can now create sockets on behalf of services before spawning any
of them, and pass the open socket fd as fd 3. CLocalServer gains a method to
complete the takeover and listen on the passed fd.
This is not used by any services at the moment.
When reaping a child, SystemServer will now match up child's pid with its own
record of the services, and respawn the service if keepalive is enabled for it.
For example, we want to restart the WindowServer if it crashes, but we wouldn't
want to restart the Terminal if it gets closed.
