Methods and systems for optimizing a build order of component source modules comprises creating a dependency graph based on dependency information. Historical build information associated with previous build failures is then used to calculate relative failure factors for paths of the dependency graph; and the relative failure factors are used to determine an order of traversal of the dependency graph during a build process in which component binary modules are built from the component source modules.

Using build history information to optimize a software build process

Some embodiments of the inventive subject matter are directed to a debugging system ('system') configured to access a work flow document. The workflow document may include references to flow activities connected by flow connectors, forming a workflow path. Some of the flow connectors may have breakpoints. The debugging system can insert command instructions for a hypertext transfer protocol (HTTP) request into the workflow document at locations associated with the flow connectors and initiate a test run of the workflow path. In some embodiments, during the test run, when one of the flow connectors is reached, the system executes the command instructions for the HTTP request, sending the HTTP request to a debugger application ('debugger'). If a breakpoint is associated with the flow connector, the debugger can delay response to the HTTP request, otherwise the debugger can respond immediately. A user can debug the workflow document during the delay.

Debugging workflows

A computer implemented method, system, and computer program product for authenticating a remote host to a firewall. The illustrative embodiments allow a requesting host separated from a target host by a firewall to determine, based on exception handling code, that an original request sent to the target host has been intercepted and blocked by the firewall. The illustrative embodiments also allow the requesting host to automatically provide credentials that authenticate the requesting host to the firewall. The illustrative embodiments are particularly applicable in situations when requests are invoked without any user interaction, such as when a timer expires. In such a case, there is no user to provide the needed credentials to authenticate the requesting host. The illustrative embodiments enable a requesting host to access a target host without requiring user intervention.

Authenticating a remote host to a firewall

Resources are retrieved asynchronous through the use of resource requests to a feed server. When the feed server returns an initial requested resource, a URI for a next resource is sent to the requesting subscriber. The URI for the next resource was pre-generated by the feed server before the next resource was created, thus allowing the subscriber to have a pending asynchronous resource request at the feed server. This resource request persists on the feed server until the new resource becomes available.

HTTP-based publish-subscribe service

Embodiments of the present invention address deficiencies of the art in respect to multi-source messaging and provide a method, system and computer program product for sequencing multi-source messages for delivery to multiple destinations. In one embodiment, a multi-source message synchronization data processing system can be provided. The system can include a common clock and a message server configured for communicative coupling to a multiple message sources, each message source including a corresponding clock synchronized with the common clock. Multi-source message sequencing logic can be coupled to the message server and can include program code enabled to concatenate different message sequences produced by different ones of the message sources into a unified message sequence based upon timestamps applied by the message sources to messages in respective ones of the message sequences.

Sequencing multi-source messages for delivery as partial sets to multiple destinations

A mediation server assigns customized 'plug-ins' to particular network access servers (NAS) that allow a service provider application to use a single interface to communicate with multiple types of NASs. Vendor specific details of NAS transaction processing are hidden in the customized plug-ins implementations in which a service provider application has no knowledge of such transaction processing information. The mediation server extracts a user identifier from a call request, and uses the user identifier to select a mediation handler plug-in. The mediation server then uses the mediation handler plug-in to communicate with a particular NAS. In addition, a RADIUS server uses a NAS identifier to assign a RADIUS handler plug-in to a NAS session, and uses the assigned RADIUS handler plug-in to communicate with the NAS.
