private

Populate the _collections cache.

◆ _removeFromCache()

void mongo::MMAPV1DatabaseCatalogEntry::_removeFromCache ( RecoveryUnit *  ru,
StringData  ns 
)
private

Drop cached information for specified namespace.

If a RecoveryUnit is specified, use it to allow rollback. When ru is null, removal is unconditional.

◆ _removeNamespaceFromNamespaceCollection()

void mongo::MMAPV1DatabaseCatalogEntry::_removeNamespaceFromNamespaceCollection ( OperationContext *  opCtx,

private

◆ _renameSingleNamespace()

) const
virtual

Implements mongo::DatabaseCatalogEntry.

◆ close()

virtual void mongo::MMAPV1DatabaseCatalogEntry::close ( OperationContext *  opCtx)
inlinevirtual

Must be called before destruction.

◆ createCollection()

Status mongo::MMAPV1DatabaseCatalogEntry::createCollection ( OperationContext *  opCtx,

virtual

Implements mongo::DatabaseCatalogEntry.

◆ createNamespaceForIndex()

void mongo::MMAPV1DatabaseCatalogEntry::createNamespaceForIndex ( OperationContext *  opCtx,
StringData  name 
)

Creates a CollectionCatalogEntry in the form of an index rather than a collection.

MMAPv1 puts both indexes and collections into CCEs. A namespace named 'name' must not exist.

◆ currentFilesCompatible()

Status mongo::MMAPV1DatabaseCatalogEntry::currentFilesCompatible ( OperationContext *  opCtx) const
virtual

Returns whethers the data files are compatible with the current code:

  • Status::OK() if the data files are compatible with the current code.
  • ErrorCodes::CanRepairToDowngrade if the data files are incompatible with the current code, but a –repair would make them compatible. For example, when rebuilding all indexes in the data files would resolve the incompatibility.
  • ErrorCodes::MustUpgrade if the data files are incompatible with the current code and a newer version is required to start up.

Implements mongo::DatabaseCatalogEntry.
