lint-shell-scripts searches over the repository looking for shell
scripts. On those found, shellcheck is run against them. If any linting
fails print those warnings and exit with a non-zero exit code.
Run this script automatically in Travis.
Warnings fixed:
* SC2086: Double quote to prevent globbing and word splitting.
* SC2006: Use $(...) notation instead of legacy backticked `...`
* SC2039: In POSIX sh, echo flags are undefined
* SC2209: Use var=$(command) to assign output (or quote to assign string)
* SC2164: Use 'cd ... || exit' or 'cd ... || return' in case cd fails
* SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
* SC2034: i appears unused. Verify use (or export if used externally)
* SC2046: Quote this to prevent word splitting.
* SC2236: Use -z instead of ! -n.
There are still a lot of warnings in Kernel/run about:
- SC2086: Double quote to prevent globbing and word splitting.
However, splitting on space is intentional in this case, and not trivial to
change. Therefore ignore the warning for now - but we should fix this in
the future.
This server listens on port 8000 and serves HTML files from /www.
It's very simple and quite naive, but I think we can start here and
build our way to something pretty neat.
Work towards #792.
We can now participate in the TCP connection closing handshake. :^)
This implementation is definitely not complete and needs to handle a
bunch of other cases. But it's a huge improvement over not being able
to close connections at all.
Note that we hold on to pending-close sockets indefinitely, until they
are moved into the Closed state. This should also have a timeout but
that's still a FIXME. :^)
Fixes#428.
If we're running more on a TTY that we don't have filesystem access to,
we can't rely on open(ttyname(STDOUT_FILENO)). Since all the stdio fd's
are opened read/write anyway, we can just read from stdout, even if it
feels a bit weird. :^)
It doesn't look healthy to create raw references into an array before
a temporary unlock. In fact, that temporary unlock looks generally
unhealthy, but it's a different problem.
Calling shutdown prevents further reads and/or writes on a socket.
We should do a few more things based on the type of socket, but this
initial implementation just puts the basic mechanism in place.
Work towards #428.
The idea behind WeakPtr<NetworkAdapter> was to support hot-pluggable
network adapters, but on closer thought, that's super impractical so
let's not go down that road.
