bitbake: prserv/serv: Multithread the server

2013-08-28T23:13:22+00:00

This makes the PR server multithreaded and able to handle multiple connections at once which means its no longer a build bottle neck when serving one connection at a time. I've experimented and database connection for each thread seems to cause the least issues, pushing the contention for sqllite to handle itself. This means moving the db/table connection code into the actual function methods. It doesn't abstract well as a function since we need the db object around for the lifetime of the function as well as the table else we lose the connection.

bitbake: prserv/db: Threading fixes

2013-08-28T23:13:22+00:00

Enabling threading for the PRServer causes a number of issues. Firstly is the obtuse error: sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type which is due to the class not being derived from object. See: http://docs.python.org/2/library/sqlite3.html#registering-an-adapter-callable Secondly, we want to enable multithreadded access to the database so we do this when we open it. This opens the way up to multithreading the PR server. (Bitbake rev: 5709efc2ff1e36529bd28f49cd093ccfa7abff7f) Signed-off-by: Richard Purdie

bitbake: serv.py: Fix regression from 972bc43e6d5b

2013-08-28T08:29:46+00:00

commit 972bc43e6d5b1207b944b3baa8f9805adb35dda7 (serv.py: Fix hang when spawned dynamically with bitbake) introduced a regression, because the wrong patch was submitted. The syntax was incorrect in the original patch. The logger iterator must be used with a call to getLogger().

bitbake: serv.py: Fix hang when spawned dynamically with bitbake

2013-08-27T23:25:56+00:00

The PRServer has the possibility to hang indefinitely blocking on a semaphore processing a xmlrpc request to send an event back to the main bitbake instance. This was observed during a "bitbake -e" on a heavily loaded machine and the main bitbake instance and cooker exited before the PRServer emitted its first log. The stack trace is provided below as to show what happens every time a logger.info() is executed in the PRServer. Not only does it write to the stream handler but it also tries to send the event to the main event processor. self._notempty.acquire() self.queue.put(event) _ui_handlers[h].event.send(event) fire_ui_handlers(event, d) fire(record, None) self.emit(record) hdlr.handle(record) self.callHandlers(record) self.handle(record) self._log(INFO, msg, args, **kwargs) (self.dbfile, self.host, self.port, str(os.getpid()))) self.work_forever() pid = self.daemonize() self.prserv.start() singleton.start() self.prhost = prserv.serv.auto_start(self.data) cooker.pre_serve() bb.cooker.server_main(self.cooker, self.main) self.run() code = process_obj._bootstrap() self._popen = Popen(self) self.serverImpl.start() server.detach() server = start_server(servermodule, configParams, configuration) ret = main() It was never intended for the PRServer to send its logs anywhere but its own log file. The event processing is an artifact of how the PRServer was forked and it inherits the event log handlers. The simple fix is to clean up and purge all the log handlers after the fork() but before doing any of the typical PRServer work or logging.

bitbake: server/xmlrpc/prserv: Add sane timeout to default xmlrpc server

2013-08-26T10:29:46+00:00

The standard python socket connect has long timouts which make sense for remote connections but not local things like the PR Service. This adds a timeout parameter to the common xmlrpc server creation function and sets it to a more reasonable 5 seconds. Making the PR server instantly exit is a good way to test the effect of this on bitbake. We can remove the bodged timeout in the PRServer terminate function which has the side effect of affecting global scope.

bitbake: prserv/serv: Fix pid file removal

2013-08-23T16:43:40+00:00

Mark Hatle spotted there were pid files being left around. This patch fixes things so the removal function is called correctly, the code contained a typo. (Bitbake rev: c696a16c8200c31c52750037eeafe07e065b6517) Signed-off-by: Richard Purdie

bitbake: prserv: Adapt autostart to bitbake-worker

2013-06-14T11:52:57+00:00

With the change to bitbake-worker we need to ensure the workers know how to contact the PR service, the magic 0 port and singleton is no longer enough. (Bitbake rev: c761751e259bb8e940552a28794b45887b5a72d9) Signed-off-by: Richard Purdie

bitbake: prserv/cooker: Handle PRService errors cleanly

2013-05-03T15:24:13+00:00

Current if the PR Service fails to start, bitbake carries on regardless or hangs with no error message. This adds an exception and then handles it correctly so the UIs correctly handle the error and exit cleanly.
