The described technology is generally directed towards configuring a client device with client configuration data based on client context data. The configuration data can include endpoints of various services to which the client can connect that are appropriate for the client device based on the client context data, along with dimension information (route key values) for connecting to each such service. For example, a roaming client device can be given an endpoint and dimension information to connect to a content service in the roaming region, with a different endpoint and dimension information for communicating user information to a home region to which the user is affiliated. This facilitates single hop/reduced latency for content requests, and compliance with home regulations via a single hop to the home service.

Client device configuration based on client context

Provided is a system and method for resiliency testing at a session level. A fault injection request is received from a client device associated with a user, via a user interface. The fault injection request defines an active impairment of one of a service or an endpoint with a blast radius restricted to a scope of the received fault injection request. The scope of the received fault injection request corresponds to a first session in a production environment or a lower environment. A client request is received from the client device within the blast radius of the active impairment. Based on the fault injection request and a persistence within the blast radius, the one of the service or the endpoint is impaired in the first session. A response, received from an entity associated with the one of the service or the endpoint, is transmitted to the client device.

System and method for resiliency testing at a session level

The described technology is generally directed towards caching session state data on a client device, so that services called by the client device and other services can use the session state data without having to recollect such information from a server or servers that maintain the ground truth values for the session state data. The session state data can be divided into payload datasets based on domains or the like, so that only a relevant part of the session state data need be attached to a given communication, and/or updated when a session variable changes in some way. A payload dataset can be encoded or encrypted so that a service can verify the integrity of the payload dataset before using it, such as for service-to-service communication.

Session state data distribution via client devices

A device may be configured to enable a user to select a language, and may fulfill resource requests from applications by selecting, from among resources respectively associated with a language, a resource associated with the selected language of the user. However, this resource selection process may be inadequate if the user selects multiple languages; if a resource associated with the selected language of the user is unavailable, but resources associated with related languages are available; or if the user and/or the application specifies an ordering for the selection among the languages. Presented herein are techniques for performing the resource selection by, for respective languages selected by the user, calculating a weight representing a suitability of the language for the resource request; generating a selection order of the selected languages according to the weights; and selecting a resource based on the position of the associated language in the selection order.

Language lists for resource selection based on language text direction

Architecture that facilitates the package partitioning of application resources based on conditions, and the package applicability based on the conditions. An index is created for a unified lookup of the available resources. At build time of an application, the resources are indexed and determined to be applicable based on the conditions. The condition under which the resource is applicable is then used to automatically partition the resource into an appropriate package. Each resource package then becomes applicable under the conditions in which the resources within it are applicable, and is deployed to the user if the user merits the conditions (e.g., an English user will receive an English package of English strings, but not a French package). Before the application is run, the references to the resources are merged and can be used to do appropriate lookup of what resources are available.

Resource deployment based on conditions

One or more techniques and/or systems are provided for generating a bundle package, digitally signing the bundle package, selectively disturbing the bundle package, and/or indexing one or more resource packages retrieved from the bundle package. That is, a bundle package (e.g., an application or game bundle package) comprises one or more app packages comprising application code configured to execute on various computing environments (e.g., operating systems, processors, etc.). The bundle package may comprise one or more resource packages comprising supplemental data used to provide optional user experience functionality for the application (e.g., French language support, high resolution textures, a gaming pad support, etc.). In this way, a client device may selectively download portions of the bundle package that may be relevant, which may mitigate download bandwidth, storage space, or resources otherwise used to obtain unnecessary portions of the bundle package (e.g., a tablet device may merely download low resolution textures).

Bundle package generation

Architecture that provides a unified interface to access resources in different formats and in disparate resource locations for a process (e.g., consuming application). The unified interface is extensible such that users can add additional components to the unified interface to provide access to new resources and new resource references. The interface provides the capability to create a single comprehensive index of all available resources regardless of the resource format. Format-specific indexers are provided for the resources to find, enumerate, and process the resources into a structure suitable for processing by an indexing component into the index. A user can introduce new format-specific indexers for new resources and new resource references for processing by the indexing component into the index. The unified interface now provides access to the new resources and new resources references as well.

Unified access to resources

Resource package indexing

A resource index on a computing device identifies multiple resource instances (e.g., multiple user interface (UI) resource instances) of multiple resource items (e.g., of multiple UI resource items), each resource instance having one or more resource instance conditions. In response to a request for a resource item received from an application, a determination is made based on the resource index of one of the multiple resource instances that satisfy conditions associated with the request, and the one of the multiple resource instances is returned to the application. Additionally, the resource index can be used to identify potential errors in running an application in various potential contexts.

Tampering with pieces of software is inhibited. Profiles are stored in a central hierarchical database and such profiles are protected from tampering. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided. A process of verifying whether the pieces of software together constitute a software package that requires protection from tampering is also provided.

Profile protection

Tampering with pieces of software is inhibited. Hardware protection prevents hackers from forcing various pieces of software from running on unauthorized pieces of hardware. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided. Image verification ensures the originality of the pieces of software to be installed.

A process of verifying whether the pieces of software together constitute a software package that requires protection from tampering is also provided. Another process for determining whether the hardware resources, such as the central processing unit or the cache memory on a computing machine, belong to a class for which inhibiting software tampering is possible, is also provided.
