* bitbake: prserv/serv: Settle on two threads for optimal performanceRichard Purdie2013-09-011-14/+34
| | | | | | | | | | | | Using the threading mixin class resulted in large amounts of memory being used by the PR server for no good reason. Using a receiver thread and a thread to do the actual database operations on a single connection gives the same performance with a much saner memory overhead so switch to this.

* bitbake: serv/db: Don't use BEGIN/COMMITRichard Purdie2013-09-011-13/+3
| | | | | | | | | | Since we don't support using multiple servers on the same database file, don't use the BEGIN/COMMIT syntax and allow writes to the database to work ~100 times faster with no transaction locking.

* bitbake: serv/db: Take an excluside lock on the databaseRichard Purdie2013-09-011-1/+1
| | | | | | | | | We only support one server using the database at a time so take an exclusive lock and avoid later lock overhead. (Bitbake rev: e3e39be6f2d063858c92971ce8ccd89c95d4f26d) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* bitbake: serv/db: Fix looping upon database locked issuesRichard Purdie2013-09-011-3/+4
| | | | | | | | | | | | | If the database is locked we will get an immediate error indicating so, there is no retry timeout. The looping code is therefore useless, the loop count is near instantly exceeded. Using a time based retry means we can wait a sensible time, then gracefully exit.

* bitbake: prserv: Allow 'table is locked' matching for retry loopRichard Purdie2013-08-301-1/+1
| | | | | | | | | Try and avoid errors like "ERROR: database table is locked: PRMAIN_nohist" by retrying if we see the string "is locked". (Bitbake rev: 1a175b51f80d13f747b653d29e9c0d2201b5109c) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* bitbake: prserv/serv: Multithread the serverRichard Purdie2013-08-291-9/+15
| | | | | | | | | | | | | | | 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 fixesRichard Purdie2013-08-292-4/+4
| | | | | | | | | | | | | | | | | 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 <richard.purdie@linuxfoundation.org>
* bitbake: serv.py: Fix regression from 972bc43e6d5bJason Wessel2013-08-281-1/+1
| | | | | | | | | | | | | | | 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 bitbakeJason Wessel2013-08-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 serverRichard Purdie2013-08-261-3/+0
| | | | | | | | | | | | | | | | | 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: bitbake: Always use separate process for PR ServiceRichard Purdie2013-02-061-22/+7
| | | | | | | | | | | | | | | Using the threading module interacts badly with multiprocessing used elsewhere in bitbake under certain machine loads. This was leading to bitbake hanging on Ctrl+C when the PR Server was being used. This patch converts it to always use the daemonize code which then means the threading code isn't required.

* bitbake/PRservice: Added no_hist mode and export/import.Lianhao Lu2012-01-113-70/+250
| | | | | | | | | | | | | | | | | | | | | | | | | [YOCTO #1556] 1. Added the package_arch into the index to the DB table. Because the change in PACKAGE_ARCH will results in different checksum, and it is better to have seperate PR value domains for differnt PACKAGE_ARCH of the same pakcage. 2. Changed the PR service to operate in no history mode. In this mode, the for a given query tuple (version, pkgarch, checksum), the returned value will be the largest among all the values of the same (version, pkgarch). This means the PR value returned can NOT be decremented. 3. Added export function. For each (version, pkgarch) tuple, only the record with the maximum value will be exported. 4. Added import function. The record will only be imported if the imported value is larger than the value stored in the DB with the same (version, pkgarch, checksum) tuple.
