2022-07-12SERVER-65360 Handle TemporarilyUnavailableException in query execJosef Ahmad
This change attaches context to the plan executor in order to distinguish a yield request due to a write conflict from one due to a TemporarilyUnavailable error, and to handle the two cases accordingly in the query execution code.

2020-09-26SERVER-50984 Add CollectionPtr to replace usage of const Collection*Henrik Edin
It implements a yieldable interface that is used to re-load the Collection pointer from the catalog after a yield that released locks. With lock-free reads and copy-on-write on Collection instances releasing locks without notifying an AutoGetCollection at a higher level may cause its pointers to dangle if a MODE_X writer installs a new Collection instance in the catalog. CollectionPtr should be passed by const reference so a yield can notify all the way up.
2020-08-07SERVER-47885 Added lookupCollectionByXXXForRead interface to the Collection ↵Henrik Edin
catalog that returns collection as shared_ptr<const Collection> AutoGetCollectionForRead and AutoGetCollectionForReadCommand now uses this and holds the shared_ptr. They return the collection as const. Const correct various places to make this possible. Moved some logic from Collection destructors to deregister from the catalog as they may now be destroyed at a later point.

2017-03-07SERVER-27938 Rename all OperationContext variables to opCtxMaria van Keulen
This commit is an automated rename of all whole word instances of txn, _txn, and txnPtr to opCtx, _opCtx, and opCtxPtr, respectively in all .cpp and .h files in src/mongo.

2016-01-14SERVER-19377 PlanStage: make work() non-virt, add virt method doWork()Jason Rassi
Changes PlanStage::work() to be non-virtual. PlanStage::work() now updates _commonStats and calls new pure virtual method doWork().

2015-07-16SERVER-17364 Don't stash RecoveryUnits across getMoresMathias Stearn
We now tell PlanExecutors to detach from their OperationContexts and to shed all storage engine resources before stashing the ClientCursor. This is a heavier weight operation than a normal save/restoreState which is no longer allowed to change the OperationContext.

This is prep for adding more methods that need to propagate to children.

Operations: sed -i -e 's/\<DiskLoc\>/RecordId/g' sed -i -e 's/\<DiskLocs\>/RecordIds/g' sed -i -e 's/\<minDiskLoc\>/RecordId::min()/g' sed -i -e 's/\<maxDiskLoc\>/RecordId::max()/g' sed -i -e 's/\<getDiskLoc\>/getRecordId/g'' Changes under mmap_v1 were reverted and redone by hand as needed.
2014-11-20SERVER-15675 Stages should clear their OperationContext in saveState()Jason Rassi
While state is saved, threads pass in their own OperationContext to invalidate(). When state is restored, the stage will resume with the OperationContext passed in to restoreState().
2014-11-20SERVER-15675 PlanStage::invalidate() needs OperationContextJason Rassi
PlanStage::invalidate() is always called by a different thread than the stage's owning thread. The method should use the active OperationContext (the caller's) rather than the stage's OperationContext.
2014-11-04SERVER-15665 MMAP v1 requests yields during page faults via NEED_FETCHDavid Storch
2014-09-18SERVER-15187 Update saved OperationContext in all PlanStagesDavid Percy
Every stage that has a field of type OperationContext* should be updating it when ::restoreState(OperationContext*) is called. Otherwise it is retaining a reference to deleted memory. This bug hasn't surfaced before because: 1. the OperationContext used to be stack allocated, so it would have the same address every time 2. mmapv1 doesn't always need to dereference the OperationContext Closes #781 Signed-off-by: Benety Goh <benety@mongodb.com>
2014-09-16SERVER-15187 Add OperationContext parameter to restoreStateDavid Percy
Storage engines might need the current OperationContext to restore their state. For example, BDBRecordIterator needs access to the current underlying transaction to recreate an underlying cursor. Having the BDBRecordIterator save a pointer to the OperationContext it was created with won't work, because the OperationContext is destroyed and a new one created between saveState and restoreState.
