this hack is trying to achieve. It never worked without -d, because
mainpid got assigned the wrong pid. It doesn't make sense with recent
versions of Linux pthreads, which use the same PID for all threads, as
required by POSIX. Remove. Closes#1161397.
empth_request_shutdown,loc_BlockMainThread,empth_init,
service_ctrl_handler) [_WIN32]: Remove the Windows Build UI and
replace with Ctrl-c signal trap. The shutdown event that was used for
STOPPING the service is now used for both foreground and background
(service) modes of operation. Also move the shutdown event from service
code to empth_t library.
empire thread debugging for Windows build.
(empth_select) [_WIN32]: Fix empth_select() so can be aborted.
The bug was that a command would not be aborted during an update.
The problem was select() was not interrupt by the setting of the
signalling wakeup event. Fix by replacing the select() with
WSAEventSelect().
(empth_exit) [_WIN32]:
Fix the shutdown sequence for Windows build to be running in
empth_t context. Add a loc_RunThisThread() in empth_exit()
before starting the shutdown() sequence.
_vsnprintf from the WIN32 library for changes to logerror().
(main) [_WIN32]: Add typedef for pid_t to match WIN32 definition
for getpid(). This is required for the create_pidfile() changes.
initial patch.
(create_pidfile, pidfname): New.
(start_server): Create pid file.
(finish_server): Remove pid file.
(main) [__linux__ && _EMPTH_POSIX]: Don't hack pid into argv[0].
Recent versions of Linux pthreads no longer show multiple PIDs, and
deities can get the PID fro the pid file anyway.
an odd case where signals were not catched when debugging.
(main, empth_start): Using sa_handler with SA_SIGINFO is wrong.
Simply don't set SA_SIGINFO; the additional signal information is not
used anyway.
(service_main,main,shutdown,empth_exit,service_stopped) [_WIN32]:
Add shutdown Event to allow the service to shutdown.
When SERVICE_STOPPED is passed to SetServiceStatus() all
threads are kills this prevents shutdown() from executing.
The shutdown Event is used to block the service_main thread until
the stopping of the service is started. After the shutdown() is
complete then the SetServiceStatus() is called.
* Acquire resources before daemonizing, fail in foreground
* Initialize threads and signals after daemonizing
* Make most file names relative to data directory
* emp_server and files make it their working directory
* emp_config() no longer screws up some file names
* Missing or incorrect econfig is now fatal
* Don't log to default log file when econfig changes it
