Appl. No.:

09/774149

Inventors:

David Erb - Seattle WA

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1100

US Classification:

702120, 707 10

Abstract:

The present invention provides systems and methods for generating sets of test cases and extends to the sets of test cases and processes using the sets of test cases to develop applications. One aspect of the invention provides a data structure for efficiently storing a set of variable value combinations among which the number of variables can vary. Another aspect of the invention provides systems and methods for sequentially generating test cases to encompass a set of variable value combinations. Advantages of the invention include permitting efficient generation of near minimal sets of test cases that include specified variable value combinations, among which the number of variables can vary, and seed test cases. Sets of test cases produced by the invention are distinctive and have practical value in processes for application development. The test cases permit more efficient and thorough testing of applications, which results in better applications.

Abstract:

Lossless, context-free data compression is implemented using a data aware compression scheme that is specific to the type of data being compressed. A modified delta compression scheme is used in which difference information is encoded with reference to a set of typical difference values that commonly occur for the type of data being compressed. Selecting the compression scheme based on the type of data being compressed allows highly-compressed, yet lossless, compression. In addition, the contextual information required to uncompress information is reduced or eliminated, thereby enabling random access of the compressed data.

US Classification:

709223, 709206, 717130

Abstract:

Profile controls for profiling a distributed application are included in messages that are also used by the distributed application to transport data. A profile initiator causes profile controls to be inserted in the header portion of a message that is being transported across a distributed system. The profile initiator may insert profile controls directly or may cause a message router that receives the message to merge profile controls into the message. The message router may receive profile controls from the profile initiator or from computer-readable media that are maintained at the message router. The message, which now includes distributed application data and profile controls, is routed to a message recipient. The message recipient accesses the message to identify profile actions that are to be performed at the message recipient. The message recipient performs at least one of the identified profile actions.

Abstract:

In one general aspect, this document describes a computer-implemented method for creating buckets in a hosted storage platform. The method may include receiving, at a hosted storage computer system that utilizes a single namespace across data stores of the hosted storage computer system, a request from a user of the hosted storage computer system to create a bucket having a name that includes a domain name. The method may also include verifying that the user is an authorized manager of a domain that corresponds to the domain name. The method may also include creating the bucket on the hosted storage computer system upon verification that the user is an authorized manager of the domain.

Abstract:

A hosted storage system receives a request from a requester to access a hosted resource. The hosted resource includes a binary large object. The hosted storage system providing hosted storage to a plurality of clients that are coupled to the hosted storage system. A copy of the hosted resource is created. A copy message including the copy of the hosted resource is provided to the requester. The hosted resource is maintained in the hosted storage system while the requester modifies the copy of the hosted resource. A message is received from the requester. The messages include a modified copy of the hosted resource. It is determined that the hosted resource has not been modified since the copy of the hosted resource was created. The hosted resource is replaced with the modified copy of the hosted resource.

Abstract:

At a hosted storage service, a resource and a request to store the resource are received. The request includes a location of an access control service. The access control service is separate from the hosted storage service and controls access permissions for the resource. A request to access the stored resource is received. The hosted storage service accesses metadata stored in association with the resource and determines that access permissions for the resource are controlled by the access control service. An access request is from the hosted storage service to the access control service, the access request identifying the resource and a user of the client system.
