* Update Scheduler to protect against infinite loopDavid James2011-03-181-4/+2
| | | | | If we have running tasks, but we're not listening to these tasks, we're going to loop forever. So throw an exception in this case.
* Scheduler: tweak prefetcher cancellation logicZac Medico2011-03-181-1/+9
| | | | | This should prevent "TypeError: an integer is required" raised from waitpid when trying to cancel a prefetcher that never started.
* Scheduler: terminate _merge_wait_queueZac Medico2011-03-181-0/+4
|
* Scheduler: fix AttributeError in _terminate_tasksZac Medico2011-03-141-1/+4
| | | | | Thanks to David James <davidjames@google.com> for reporting this error: AttributeError: 'EbuildPhase' object has no attribute 'merge'
* PollScheduler: tweek termination logicZac Medico2011-03-141-4/+4
| | | | | | | | | * PollScheduler and all subclasses now use the _terminated_tasks variable to check whether or not _terminate_tasks() has been called, and behave appropriately in that case. * The _schedule_tasks() method now has documentation about the relationship with _terminate_tasks() and _terminated_tasks.
* Scheduler: avoid infinite loop after CTRL-CZac Medico2011-03-141-1/+14
| | | | | | | | If CTRL-C was received at certain times, it was possible for discarded tasks to be erroneously left in Scheduler._running_tasks, which would cause the main loop to run infinitely. Thanks to David James <davidjames@google.com> for reporting this issue and helping to devise a solution.
* Scheduler: ensure _prefetchers is clearedZac Medico2011-02-211-0/+1

|
* Add PollScheduler.terminate() for interruption.Zac Medico2011-01-161-8/+17
| | | | | This allows PollScheduler instances to do basic cleanup and terminate gracefully when SIGINT or SIGTERM signals are received.

|
* Scheduler: cache Package instance moreZac Medico2011-01-051-9/+12
| | | | | | | | This helps to avoid some cases in which emerge crashes due to ebuild modification that leads to failure in aux_get/manifest check while the Scheduler is running. Typically such modifications are harmless, so it's beneficial to cache the metadata so that aux_get is less likely to be called when it will fail.

* Bug #336651 - Fix Scheduler._restart_if_necessary() to correctlyZac Medico2010-09-091-1/+5
| | | | | handle arguments like --exclude that are stored as a list since they use the 'append' action.

* Make Scheduler._set_graph_config() clear _deep_system_deps whenZac Medico2010-09-061-0/+2

* Move the Scheduler mergelist constructor parameter to the graph_configZac Medico2010-09-061-13/+25
| | | | object.
* Make depgraph.schedulerGraph() return an instance ofZac Medico2010-09-061-25/+25
| | | | | | | _scheduler_graph_config instead of just a digraph. This new object includes instances of FakeVartree and a package cache that is pruned to contain only installed packages or those in the digraph.
* Make Scheduler._destroy_installed_graph() destroy _digraph.Zac Medico2010-09-051-3/+4
|
* Add scheduler._init_installed_graph() and _destroy_installed_graph()Zac Medico2010-09-041-18/+39

* Add a Scheduler._frozen_config attribute that will be useful forZac Medico2010-09-041-3/+10
| | | | | | dependency calculations related to aggressive parallelization (bug #279623). The FakeVartree instances are shared with the existing BlockerDB instances.
* When portage updates itself and the new version either inheritsZac Medico2010-08-311-3/+6
| | | | | | | | | git.eclass or has 9999 in its version, trigger the 'use copy of current sources for install, then restart portage' routine. This is required since with the live git portage-9999 ebuild we can't use the version to detect incompatible changes to ebuild.sh. This issue was noticed due to recent versions of ebuild.sh expecting PORTAGE_BZIP2_COMMAND to be set, causing incompatibility with installed portage-9999 instances.
* Rename the portage.sets module to portage._sets since it will be usefulZac Medico2010-08-301-2/+2
| | | | | in the upcoming 2.1.9 branch which will not have sets support but will still have the code in private and disabled form.
* Remove unused imports found by pylint.Arfrever Frehtes Taifersar Arahesis2010-08-291-2/+0

* Add a TODO note about replacing BlockerDB with an incremental depgraphZac Medico2010-08-291-0/+5

* Add a Scheduler._running_tasks() set in order to simplify theZac Medico2010-08-281-2/+5

* Inside Scheduler._dependent_on_scheduled_merges(), don't traverse childrenZac Medico2010-08-281-1/+5

* When accessing pkgsettings.features inside Scheduler._generate_digests(),Zac Medico2010-08-211-0/+8
