* bitbake/cache/runqueue.py: Move workload for recipe parsing to the child processRichard Purdie2011-02-281-12/+23
| | | | | | | | | | | | | | | Parsing the recipe in the parent before forking off the child worker can mean the parent doesn't hit the idle loop and becomes a bottleneck when lauching many short lived processes. The reason we need this in the parent is to figure out the fakeroot environmental options. To address this, add the fakeroot variables to the cache and move recipe loadData into the child task. For a poky-image-sato build this results in about a 2 minute speedup (1.8%). Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* bitbake/runqueue.py: Avoid starvation of events to the serverRichard Purdie2011-01-281-1/+1
| | | | | | | | | | | | | | The server UI was reading 1024 bytes, then sleeping for 0.25 seconds. Since most new LogRecord events are larger than this it leads to a build up of data which is only processed slowly, leading to a bottleneck and a slow down of all bitbake processes. Thanks to Dongxiao Xu <dongxiao.xu@intel.com> for the great work in debugging this. A large value has been left in for the read() command just to ensure some fairness amongst process handling if a task tries to log truly huge amounts of data to the server, or goes crazy and ensures the main loop doesn't stall.

* Prefer xrange over range for small performance gain.Bob Foerster2011-01-041-27/+27
| | | | | | | | | | | | | | range() allocates an actual list when called. xrange() is just an iterator and creates the next range item on demand. This provides a slight performance increase. In python 3, range will do what xrange does currently, but the upgrade will be handled by the 2to3 tool.

* Switch bitbake internals to use logging directly rather than bb.msgChris Larson2011-01-041-46/+44
| | | | | | | | | | | | | | We use a custom Logger subclass for our loggers This logger provides: - 'debug' method which accepts a debug level - 'plain' method which bypasses log formatting - 'verbose' method which is more detail than info, but less than debug (Bitbake rev: 3b2c1fe5ca56daebb24073a9dd45723d3efd2a8d) Signed-off-by: Chris Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
* Use logging in the knotty ui, and pass the log record across directlyChris Larson2011-01-041-1/+9
| | | | | | | | | | | | | | | | | | This kills firing of Msg* events in favor of just passing along LogRecord objects. These objects hold more than just level and message, but can also have exception information, so the UI can decide what to do with that. As an aside, when using the 'none' server, this results in the log messages in the server being displayed directly via the logging module and the UI's handler, rather than going through the server's event queue. As a result of doing it this way, we have to override the event handlers of the base logger when spawning a worker process, to ensure they log via events rather than directly.

* Add the ability to use runqueue schedulers from the metadataChris Larson2011-01-041-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | If you create a runqueue scheduler class in a python module, available in the usual python search path, you can now make it available to bitbake via the BB_SCHEDULERS variable, and the user can then select it as they select any other scheduler. Example usage: In a test.py I placed appropriately: import bb.runqueue class TestScheduler(bb.runqueue.RunQueueScheduler): name = "myscheduler" In local.conf, to make it available and select it: BB_SCHEDULERS = "test.TestScheduler" BB_SCHEDULER = "myscheduler" (Bitbake rev: 4dd38d5cfb80f9bb72bc41a629c3320b38f7314d) Signed-off-by: Chris Larson <chris_larson@mentor.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

| | | | | | | | | | | | SIGINT should be from the user, not a script. It also doesn't work as reliably to shut down processes, as it's not always interpreted as a termination request. In addition, it causes KeyboardInterrupt exceptions in the worker processes, which can interfere with our exception handling.

* runqueue.py: use correct task ID when checking validity of setscene tasksKevin Tian2010-12-141-5/+11
| | | | | | | | | | | | | | | | | | sstate hash validation is done at initialization of RunQueueExecuteScenequeue. However the index of 'valid' list returned from the validation doesn't correspond to setscene task ID. It's just an intermediate namespace between runqueue and sstate hash func. Use it as setscene task ID fully mess the flow. Previously this doesn't cause trouble because all setscene tasks are passed. Commit 58396a5d24c62710fd0a9f3780d84ac8a95d8e7c add 'noexec' concept to setscene tasks which grabs some tasks out of the list and thus trigger this problem Without this fix there're ~50 recipes (gzip-native, glib, ...) rebuilt weirdly with a minimal build, even though existing sstate packages could accelerate them. there's another typo using wrong task ID in a debug message which further hide this issue Signed-off-by: Kevin Tian <kevin.tian@intel.com>
* bitbake: Overhaul environment handlingRichard Purdie2010-12-091-0/+1
| | | | | | | | | | | | | | Currently, anything whitelisted in the environment makes it into the worker processes. This is undesireable and the worker environment should be as clean as possible. This patch adapts bitbake sosme variables are loaded into bitbake's datastore but not exported by default. Any variable can be exported by setting its export flag. Currently, this code only finalises the environment in he worker as doing so in the server means variables are unavailable in the worker.
