Facilitating navigating presentations of data structures in a computing environment. A method includes detecting user input for navigating to a location in a presentation of a data structure stored at a computing system. The method further includes as a result of detecting user input for navigating to a location in the presentation of a data structure, outputting from an accessibility compliant interface at the computing system, at least a portion of a notification identifying the location in the presentation of a data structure. The method further includes, as a result of detecting user input for navigating to a location in the presentation of a data structure, outputting from the accessibility compliant interface at the computing system, at least a portion of an enumeration of tokens for predetermined items of import relevant to the location.

Accessible metadata in data structures

Described is installing multiple software packages to a computing device in a single transaction, whereby the multiple package installation commits if successful, or the device is rolled back to a determined state if unsuccessful. A client process provides a system service (installer) with a package, and the service partitions package installation actions into execution, commit and rollback phases, with the execution phase run for each package. If successful, the transaction is committed by performing the multiple commit phases. If unsuccessful, the installation is rolled back via the rollback phases. The phases may be interleaved, with execution and commit phases performed in FIFO order, and rollback phases performed in LIFO order. A client process may dynamically determine which packages to install, a client process may be embedded in a package and join the transaction, and/or one client process may delegate control to another client to add package actions to the transaction.

Transactional multi-package installation

Deploying applications to a device often involves generating an application package for installing the application anew, and application patches for updating the application from a specific first version to a specific second version. Presented herein are alternative techniques for deploying the application to devices using a block map indicating hashcodes for respective blocks of respective resources of the application. A device may install the application by installing the application package, or may update a deployed application from an earlier version to a later version by retrieving the block map, identifying updated blocks having a different hashcode than the current hashcode of the block in the currently deployed application, and retrieving only the updated blocks. The block map also enables concurrent deployment of multiple application versions, and resource sharing among deployed versions and variants by sharing commonly used blocks and retaining alternatives of blocks differing between such versions and variants.
