Abstract: In some embodiments, a client generates an operation modifying a local copy of a content item on a user account at a content management system and records an intent to commit the operation to a journal of revisions at the content management system. Based on the operation, the client sends to the content management system a first request to commit the operation at the journal, the first request including a cursor identifying a current position of the client in the journal. The client sends, to the content management system, a second request for a status of the commit and, based on the second request, determines whether the commit of the operation to the journal has succeeded. Based on whether the commit of the operation to the journal has succeeded, the client determines whether to update one or more tree data structures on the client and clear the intent to commit.

Abstract: A verification device operates to evaluate consistency of input values from a client device used by a server to execute a task. In an example the task may be installation of software into the client device, and the consistency evaluation of the input values may involve evaluating whether identifiers used to obtain attribute values of components of the client device for the installation apply to the same client device. To initiate execution of the task, the client device commands a plurality of data source servers to supply the attribute values. The data source servers return response messages defining the attribute values associated with the identifiers supplied by the client device. The client device supplies the response messages to the server for use in the execution of the task.

Abstract: In response to receiving a request from a client to store an object, a key-durable storage system may assign the object to a volume in its data store, generate a key for the object (e.g., an opaque identifier that encodes information for locating the object in the data store), store the object on one disk in the assigned volume, store the key redundantly in the assigned volume (e.g., using a replication or erasure coding technique), and may return the key to the client. To retrieve the object, the client may send a request including the key, and the system may return the object to the client. If a disk fails, the system may determine which objects were lost, and may return the corresponding keys to the appropriate clients in a notification. The system may be used to back up a more expensive object-redundant storage system.

Abstract: Systems, methods, and computer-readable medium are provided for presenting a synchronized content scrubber. For example, a user device may store digital content items for presentation on a screen of the user device. A user interface may be configured with multiple viewing areas.

However, in the second viewing area, the image that represents the content item may be presented in a visually distinct manner from other images in the second viewing area.

Abstract: Each object is associated with one root metadata record and one or more version-specific metadata records, each corresponding to a version of object data. A conditional command may be conditioned upon whether an object is stored in a storage system. Whether the condition is satisfied is determined based on whether a root metadata record of the object exists. If the condition is satisfied, then metadata is updated to reflect execution of the conditional command. A conditional command may be conditioned upon whether a data version identifier or a metadata version identifier equals a particular value. A conditional command execution engine retrieves the relevant version identifier from a version-specific metadata record, and performs a check on whether the condition is satisfied. If the condition is satisfied, the engine ensures that the version-specific record has not been modified during the check, and updates metadata to reflect execution of the conditional command.

Abstract: Optimized techniques are disclosed for sorting variable-length records using an optimized amount of memory while maintaining good locality of references. The amount of memory required for sorting the variable length records is optimized by reusing some of the memory used for storing the variable length records being sorted.

When all the records of a memory page of an input run have been processed or copied to the merged run, that memory page can be emptied and released to a cache of empty memory pages. Memory pages available from the cache of empty memory pages can then be used for generating the merged run.

Abstract: A software developer tool allows for live code updates (LCU) while an application is running using an execution platform. The LCU update service operates by preemptively, automatically rewriting bytecode to introduce a layer of indirection that swaps out the code of a running application to make it easy to dynamically update whenever the code is changed. The indirection includes both new “representation” classes (and constituent fields and methods), and also replacing constructs that are hard-coded into the bytecode with more flexible constructs such as representation object maps and a dynamic global class table. All manner of code modifications are handled including adding, removing and modifying fields and methods of classes, and changing the class hierarchy. This includes arbitrary code changes, ensuring that when a developer changes a class, all objects of or related to that class are instantly updated.

Abstract: To deliver up-to-date, coherent user data to applications upon request, the disclosed technology includes systems and methods for caching data and metadata after it has been synchronously loaded—for future retrieval with a page load time close to zero milliseconds. To provide this experience, data needs to be stored as locally to a user as possible, in the cache on the local device or in an edge cache located geographically nearby, for use in responding to requests. Applications which maintain caches of API results can be notified of their invalidation, and can detect the invalidation, propagate the invalidation to any further client tiers with the appropriate derivative type mapping, and refresh their cached values so that clients need not synchronously make the API requests again—ensuring that the client has access to the most up-to-date copy of data as inexpensively as possible—in terms of bandwidth and latency.
