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.
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.
It used to only read the data it could get without blocking. Andreas says this
was intentional, but it's counterintuitive and no code that uses read_all()
actually expects it to return only a part of the data. So change it to always
read data until an EOF (or an error) is received.
We were returning a zero-length ByteBuffer in some cases. We should be
consistent about this and always return a null ByteBuffer if nothing
was read at all.
There's some confusion between the write syscall and CIODevice::write()
here. The internal write() returns a boolean, and has already whined
in case the syscall failed, so we don't need to do that again.
Add a trivial CSafeSyscall template that calls a callback until it stops
returning EINTR, and use it everywhere we use select() now.
Thanks to Andreas for the suggestion of using a template parameter for
the syscall function to invoke.
