Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generated aggregated dependencies between software elements in a code base. One of the methods includes processing selected software elements as represented by a raw dependency graph and a hierarchy graph to generate data representing an aggregated dependency graph, the aggregated dependency graph having nodes representing the selected software elements and aggregated dependencies between one or more of the selected software elements, wherein each aggregated dependency between a pair of the selected software elements represents that a first software element of the pair, or a descendant of the first software element according to the hierarchy graph, depends, according to the raw dependency graph, on a second software element of the pair or a descendant of the second software element according to the hierarchy graph. The data representing the aggregated dependency graph is provided in response to the request.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using tiered arrays to represent aggregated software dependencies. One of the methods includes receiving a request to generate a range of contiguous indexes having non-default values represented by a tiered array, wherein each non-default element of each tier is a reference to a catalog at a lower tier except for a bottom-most tier of the tiered array that stores non-default values. After descending one or more tiers to identify a first index that (i) is greater than or equal to the start index and (ii) has a non-default value, a system ascends one or more tiers in the tiered array and subsequently descends again to identify a second index that is a last index in a contiguous sequence of indexes having non-default values from the first index up to and including the second index.

The present technology adds code to a top level build configuration file of a configuration program that will gather metrics for each invocation of a build. These metrics are sent to a commonly accessible metric server for future analysis. The metrics are collected for a distributed engineering team over several machines. Compilation time metrics may then be collected for each compilation event and those metrics are analyzed by a common aggregator.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generated aggregated dependencies between software elements in a code base. One of the methods includes receiving a request to generate implicit dependencies introduced by remote procedure calls in a project. A registration of a remote procedure call is identified, wherein the registration of the remote procedure call specifies a target function and a name for the remote procedure call. An invocation of the remote procedure call using the name for the remote procedure call is identified, wherein the invocation occurs in a source software element of the project. A definition of the target function of the remote procedure call is identified, wherein the target function is defined in a target software element of the project. A new dependency is generated, the new dependency being a dependency from the source software element to the target software element.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for computing virtual compositions. One of the methods includes receiving a request to compute a virtual disjunction over three or more tiered arrays. Respective ranges of contiguously set indexes in the arrays are repeatedly compared until the end of all of the arrays is reached, including, on each iteration, determining a smallest start index n0 among current ranges of the arrays, wherein the smallest start index n0 is the first set index in a range [n0,n1], determining whether any of other arrays have overlapping ranges that extend the range [n0,n1] in the virtual conjunction, updating n1 for each other array having an overlapping range that extends the current range, outputting the range [n0,n1] the updated value for n1, and determining a next range starting at or after n1+2 for each of the arrays.

A computer-readable memory device may include instructions to store data describing a state machine model including source states and destination states. The device may also include instructions to store, for each of the source states, a condition field identifying a condition upon which, when satisfied, the state machine model transitions from the source state to one of the destination states. The device may also include instructions to store, for each of source states, a destination field identifying the one of the destination states. Each of at least two of the source states may identify an identical destination state in the corresponding destination field. Each of at least two of the source states may identify an identical condition in the corresponding condition field.

In some examples, a method for developing an application programming interface (API) is provided. The method is performed by a computing system running an API Forge Accelerator. The method comprising: receiving, by the API Forge Accelerator, a request for generating an API for a service based on a type of a first gateway, wherein the request indicates a selection of the first gateway among a plurality of gateways integrated with the API Forge Accelerator; generating, by the API Forge Accelerator, based on the specific gateway, a specification template corresponding to the specific gateway for generating the API, wherein the specification template indicates specification information that is used for the API generation; obtaining, by the API Forge Accelerator, based on the specification template, specification information from user input and API tools; and generating, by the API Forge Accelerator, based on the specification information, the API for the service.
