Device-specific chunked hash size tuning to maximize synchronization throughput is described. A synchronization client application or similar program may employ hashing to detect changes to content of remotely stored files and synchronize those (as opposed to synchronizing all files, for example). Instead of using static hash chunk sizes for all client applications of a cloud storage service, the synchronization client application may determine the size of hash buffer by baselining throughput of hashing on each synchronization device and finding the number of bytes hashed in a given amount of time. Thus, hash chunk size may be optimized on a machine by machine basis.

Device specific chunked hash size tuning

A software development architecture is provided for constructing a wide range of software development tools. A software development tool can be created by integrating a specification specifying functionality specific to a set of software development scenarios into a software development scenario-independent framework. The integrated specification can then be compiled to create the software development tool. Alternatively, integration can be achieved at runtime without access to source code. The architecture can use any combination of the following: a software scenario independent intermediate representation format, one or more exception handling models capable of supporting a plurality of programming language specific exception handling models, a type system capable of representing the type representations of a plurality of source languages, and a code generator capable of generating code targeted for a plurality of execution architectures.

Software development infrastructure

Technologies are provided for automatically generating software development tool components and associated software development tools for a target architecture via a target architecture specification. Architecture-specific information can be compartmentalized from architecture-independent information. Accordingly, development components or tools can be easily generated for another target architecture by substituting a different target architecture specification.

Generating software development tools via target architecture specification

Methods and systems are described herein for extending configuration dependent extensible software programs. Classes of a core extensible software program may be extended by adding a configuration dependent extension. The extensions may be added statically prior to compiling the core version of a software program or dynamically at runtime. The declaration of extensible core classes may include an extensibility attribute with an indication of whether the class is statically extensible or dynamically extensible. An object description language is also described herein for appropriately declaring configuration dependent extensible classes. Also, a pre-processor is described herein for processing the object description language to generate a source code representation of the extensible class declarations and their extensions. The source code representation may then be used to generate the extended version of the core software program.

Description language for an extensible compiler and tools infrastructure

Various intermediate representation techniques for software development tool scenarios are described. An intermediate representation format can be used for both high level and low level representations. The intermediate representation can be built from various operands and instructions types. Various annotations can be added to the intermediate representation without modifying its format. For example, flow control and data control can be explicitly represented by threading a graph through the intermediate representation.
