Deprecations and other changes

Deprecate SharedSequence, SubSequence, and IJSONRunSegment

The types SharedSequence, SubSequence, and IJSONRunSegment are being deprecated and moved.

They are now, and will continue to be exposed from the @fluid-experimental/sequence-deprecated package.

New usages of these types should not be added, but they may be necessary for migration.

PureDataObject temporarily extends EventForwarder and implements IDisposable again

PureDataObject extends EventForwarder and implements IDìsposable again to ease the transition to 2.0.0-internal.6.x. These interfaces will no longer be implemented on PureDataObject in version 2.0.0-internal.7.0.0.

The original deprecation announcement for these members can be found here.

Once the change is re-applied in 2.0.0-internal.7.0.0, if your code was overriding any methods/properties from EventForwarder and or IDisposable on a class that inherits (directly or transitively) from PureDataObject, you'll have to remove the override keyword.

Temporarily restore id property on IContainerContext

The id property on IContainerContext has been temporarily restored to ease the transition to 2.0.0-internal.6.x. It will be removed again in 2.0.0-internal.7.0.0.

The original deprecation announcement can be found here.

Deprecate getStackContext and associated NestBegin/End

Deprecate SharedSegmentSequence.getStackContext and Client.getStackContext (and the enums ReferenceType.NestBegin and NestEnd they use). This functionality is unused, poorly tested, and incurs performance overhead.

Deprecated refreshLatestAck in ISummarizeOptions, IOnDemandSummarizeOptions and IEnqueueSummarizeOptions

Passing refreshLatestAck as true will result in closing the summarizer. It is not supported anymore and will be removed in a future release. It should not be passed in to summarizeOnDemand and enqueueSummarize APIs anymore.

Remove use of @fluidframework/common-definitions

The @fluidframework/common-definitions package is being deprecated, so the following interfaces and types are now imported from the @fluidframework/core-interfaces package:

• interface IDisposable
• interface IErrorEvent
• interface IErrorEvent
• interface IEvent
• interface IEventProvider
• interface ILoggingError
• interface ITaggedTelemetryPropertyType
• interface ITelemetryBaseEvent
• interface ITelemetryBaseLogger
• interface ITelemetryErrorEvent
• interface ITelemetryGenericEvent
• interface ITelemetryLogger
• interface ITelemetryPerformanceEvent
• interface ITelemetryProperties
• type ExtendEventProvider
• type IEventThisPlaceHolder
• type IEventTransformer
• type ReplaceIEventThisPlaceHolder
• type ReplaceIEventThisPlaceHolder
• type TelemetryEventCategory
• type TelemetryEventPropertyType

Deprecation of findTile in favor of searchForMarker, which uses depthFirstNodeWalk to locate the nearest marker.

findTile has a decent amount of buggy behavior, which leads partners who want to use it to implement workarounds for the odd behavior. searchForMarker is being introduced as a replacement. It performs the same basic functionality of searching for the nearest marker to a given start position in the indicated direction. However, it includes the start position as one of the nodes to search, so markers at the start position will be returned as the nearest marker to that position. Notably, positions 0 and length-1 will be included in the search as well, so searching forwards from position 0 or backwards from position length-1 would allow the entire string to be searched.
