Sleep in both places before counting them, and catch Poco exceptions
while counting (can happen for instance when a /proc entry goes away
while we are looking for its 'comm' file).
Do not distinguish between normal shutdown or abnormal shutdown.
Also remove 'disconnect' frame to indicate normal shutdown.

The number of loolkit processes after running the cppunit tests should
be the same as before running them. (At least, that is the intention
at the moment, I think. If/when this changes, the test will have to be
adapted, of course.)
That global flag is checked all over the place, so setting it will
actually make the threads eventually finish. (All polling is done with
timeout, I think, and then checking TerminationFlag whenever the poll
times out.)
Sure, it would be much better to use an eventfd and poll that, too,
instead of timing out from the polls all the time to check a plain old
boolean flag.
If you can't come up with a meaningful message to use in a
CPPUNIT_ASSERT_MESSAGE(), just use CPPUNIT_ASSERT() instead. These
messages aren't intended for end-users but for developers, so it is
pointless to make them high-level and dumbed-down.
In case of abnormal termination of session from client-side,
we might still have data being processed in the kit process, for
example, during auto-save. Trying to send such data over an
expired socket towards the client would throw exceptions which
need to be handled, otherwise the auto-save process would not be
successful. Further, the unhandled exception can bring the document
broker in an unstable state with dockey still present in the
object.
Also do not send 'editlock: 0' to a websocket session which is
going to be removed because the session might have been
forcefully terminated from the client-side, in which case sending
data would go nowhere.

Enforce user being 'lool' for setcap binaries loolmount and loolforkit.
Add warnings if configured without --enable-debug.
Developers should pass --enable-debug to configure.
The loolwsd process created it and opened it for reading, but nothing
opened it for writing.
There is still documentation for it in README, that needs to be either
rewritten to match reality or removed.
Comes in handly in some testing situations where you don't want to
send a signal to get loolwsd to finish. Option is present only in an
--enable-debug build.
If the first session used to save does not hold the edit-lock,
all the .uno:Save commands will get converted to dummy messages
and never reach the kit process.

It is a status code, a 2-byte unsigned integer in network byte order,
potentially followed by a textual reason. But we never include any
specific status codes in the CLOSE frames anyway. (With a Poco-based
WebSocket peer it is always WS_NORMAL_CLOSE, 1000, 0x03 0xE8.)
Since WSD now takes into account the fact that
ForKit always spawns one child, the unit-test
shouldn't expect +1 preforked children.

Connection thread should not attempt to disconnect the session,
which in turn will try to unload the document, which will
wait on the connection to destroy. The latter will never
happen since the connection destructor must, correctly,
wait for its thread to finish, which is waiting on itself now.
Since the session disconnect is already called from the session
destructor, there is no need to explicitly invoke it here.

Autosaving is done by DocumentBroker, which
tracks the last save time.
There are two triggers: idle and auto save.
The first triggers when sufficient time passes
after the last interaction the user had with
the UI (currently 30 seconds).
The second triggers when it's been more than
5 minutes since the last save.
Both triggers are conditional on the user
being active after the last save.
The new code auto-saves doesn't issue
a save command per session, but only
one per doc.

This seems to get rid of the "terminate called after throwing an
instance of 'Poco::SystemException'" problem for me at least.
Sigh. Why can't the compiler warn about such things? I build with
clang++ -Wall -Wextra. The Connection class is fully defined inside
the LOOLKit.cpp so it should be able to, right?
Presumably it is only developers that are interested in signals, and
terms like SEGV or ABRT are more precise than their textual
descriptions like "Segmentation violation" or "Aborted".
Sleep a second before exiting in case we get a fatal signal just when
about to finish, which sadly seems to happen often. (In fact, if
handleFatalSignal() is running at the same time, it will kill the
process so we never get to the _Exit() call.)
Also, display more information about the exception.
Actually I think I should factor out the code to display as much
information as possible from an exception. Currently the amount of
information displayed varies from case to case in the code-base.
Poco::Channel is reference counted, but the initial refcount is 1, so we
need to release channel in order to have it deleted when Poco::Logger
releases it.
Calls to Poco::Logger::shutdown() are still missing though (from
forkit/kit/wsd).

Put this inside #if, add the 'override' back for current Poco. Avoids
"warning: 'expectContinue' overrides a member function but is not
marked 'override'" when compiling against current Poco.
Not sure what good it would do to define it at all if compiling
against a bleeding-edge Poco as it won't call it anyway?
The logging functions already display the thread name on all output
lines. No need to mention it another time in the thread start and
finish logging messages.
A call to Log::error() should be enough to indicate that it is an
error. We don't need to prefix the message with the string "Error: "
in some cases but not others. (If we do want such a prefix for all
errors, surely then we should add it in the actual Log::error()
function.)
Also, change some more Log::error() calls to Log::syserror() where
appropriate.
Much better than assuming that errno would be relevant at all
Log::error() calls (or alternatively, having to remember to append a
false parameter to the Log::error() call, which had not been done a
single time anyway.)
Call log::syserror() right after a system call has returned an
error. Don't call it otherwise.
Loading documents from the local filesystem

By default filesystem storage is disabled,

Most all configuration values can now be defined
in the configuration XML. The command-line arguments
can be used to override some of these values (for
the convenience of developement and testing) and,
in a few cases, as a security measure to avoid
storing sensitive data in the configuration file.
