* depgraph: migrate implicit libc deps from SchedZac Medico2011-04-301-65/+0
| | | | | Now all the virtual/libc handling is done by the depgraph, which will be helpful when fixing bug #364681.
* Remove unnecessary sync in Scheduler.py.David James2011-04-111-1/+1
| | | | | | | | | | | | | | If we are passed a fakevartree object, it should already be sync'd, so there is no need to sync it again here. This sync is only needed when we create a new FakeVartree, so I moved the sync to the right place to fix this. BUG=chromium-os:14035 TEST=Build a bunch of packages with this patch.

* Update Portage to sync BlockerDB at init.David James2011-03-241-17/+7
| | | | | | | | | | | | Currently, Portage syncs the BlockerDB before every merge. This slows down merges considerably because it requires reading the entire vardb from disk. Since Portage doesn't merge conflicting packages anyway, we can optimize this by just reading the vardb at initialization and caching that.

* Update Scheduler to protect against infinite loopDavid James2011-03-161-4/+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 Medico2011-03-161-1/+9
| | | | | This should prevent "TypeError: an integer is required" raised from waitpid when trying to cancel a prefetcher that never started.

* Scheduler: fix AttributeError in _terminate_tasksZac Medico2011-03-121-1/+4
| | | | | Thanks to David James <davidjames@google.com> for reporting this error: AttributeError: 'EbuildPhase' object has no attribute 'merge'
* PollScheduler: tweek termination logicZac Medico2011-03-101-4/+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 Medico2011-03-101-1/+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: 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.

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.
