29f17aa874 Fix race condition related to watching DGL games. 
It's possible for a dgamelaunch game to end and cause rlgwebd to stop watching
it before rlgwebd has started watching it.

9004afebdc Terminal emulation: implement the CSI b sequence. 
CSI b repeats the previous character, if it was printable and not an
escape sequence.

f2256500e1 Changes for compatibility with recent versions of NodeJS. 
The pty.js module is replaced with node-pty, now-mandatory callbacks
are added to various fs functions, and deprecated Buffer() calls are
replaced with Buffer.from() or Buffer.alloc().

4940bf86ae Move the NODE_PATH location. 
Modules are now expected to be in /var/local/lib/node_modules.  This is
intended to make it easier to avoid running npm as root.

c4d10ba33d rlgwebd-stop: avoid the deprecated domain module. 
Instead of catching connection errors with domains, install an error
listener on the socket before connecting.

61ddb2eaea Move RLGWebD configuration options into a configuration file. 
On startup, rlgwebd now reads /etc/rlgwebd.conf.  If the options for
HTTPS are not found, it will only use HTTP.

37bd2e8c28 Initial support for TLS. 
RLGWebD now serves via encrypted connections on port 8081.

accessed via HTTPS.

a94e700b58 Make sure games have saved and exited before stopping the server. 
This should make the systemd version safe for production, though
it can't yet deal with a game that hangs and doesn't exit.

"initscript".  The script files have had the ".js" extension removed
from their names.

ff0814c7ac RLGWebD: move the control socket into /var/run. 
This is a more standard location.  /run is preferred by systemd, but
portability to non-systemd systems is important.

9a709adc58 Add a script to stop RLGWebD. 
socat is no longer needed, nor is preventing systemd from sending
signals.

ec5c79d46e Begin adding systemd compatibility. 
The Makefile can be used to build and install rlgwebd.  On systems with
systemd, the unit file controls starting and stopping the service, and
the shell script is not needed.

The unit file uses KillMode=none because socat does not actually stop
rlgwebd, it only asks it to stop and exits without waiting for a
response.  Until a better stopping method is introduced, this setting
prevents systemd from killing all the rlgwebd processes as soon as
socat exits.

56024418c3 Fix further crashes when following dgamelaunch games. 
The crashes apparently resulted from reading a ttyrec header and
then trying to read the data chunk before dgamelaunch produced it.
When the data chunk did become available, it would be read by the
header function.

The simplest solution was to store the position for reading the
ttyrec file in the DGLSession, and to leave it unchanged if anything
unexpected occurs when reading.

6373e70361 RLGWebD: fix simultaneous player bug.

the proper place.  The interaction of multiple players with watchers

Failure is now signaled with a TermSession.failed flag.

Playing two games at the same time no longer causes crashes, but it
does send the same output to both players.

3c88c233b4 rlgwebd.js: prevent races when reading ttyrecs. 
DglSession objects read a 12-byte TTYREC header, extract therefrom the
length of the data chunk, and then read the data.  In between these two
reads, the file watcher could trigger another readchunk() invocation,
which might attempt to read a header from the beginning of the data
chunk.  This usually results in expecting a data chunk of several GB
and failing to create a Buffer for it.

The race is remedied by setting a flag on the DglSession object
whenever readchunk() is called, clearing it when both reads complete,
and refusing to read if it is already set.
