A dynamic linking system can be designed to dynamically resolve symbol references of pages associated with executable code as the pages are paged into virtual memory. The operating system can include a dynamic linker that uses metadata in the pages to determine symbol references that reference other code or values. Other code can include code in shared libraries. The dynamic linker can generate a data structure containing the symbol references in a small and dense format. The dynamic linker can send the data structure and other relevant data to the kernel once the symbol references have been identified. The kernel can perform the functions related to resolving the symbol references. For example, the kernel can resolve the symbol by determining a pointer value for the symbol, wherein the pointer value can be used to point to code or values. The kernel can resolve the symbol references and store the data structure, which contains the resolved symbol references.

Page-in linking

Techniques may include receiving a first request for a conformance check for a conformance pair, the conformance pair include a variable type and a particular protocol. The first request can identifying a first pointer. The technique can include determining a conformance check result is not cached for the conformance pair using the first pointer. In response to determining that the conformance check result is not cached for a variable, the electronic device may include performing the conformance check for the conformance pair and storing a result of the conformance check in an index table in persistent memory in association with at least a portion of bits in the first pointer. The technique can include referencing the index table on subsequent requests for a conformance check.

Techniques for runtime protocol conformance cache for third party

One embodiment provides for a computer-implemented method comprising generating a linked list table including a first component having linking data to be stored in a table data structure for one or more rebase and bind operations and second a component having instructions to implement the table data structure to perform the rebase and bind operations according to a linked list chain and executing the instructions in the second component of the linked list table to perform the one or more rebase and bind operations based on the linked list chain.

Threaded linking pointer mechanism

A method, apparatus, and system are provided for assigning tasks and/or providing resources in a distributed system. An indication of a task being available for processing is provided to one or more remote systems in a distributed system based on a distribution list. At least one response from one of the remote systems capable of performing the task is received in response to the indication. The response includes a request for a resource for performing the task. The resource for performing the task is provided to the remote systems.

Peer to peer component distribution

Disclosed herein are techniques for performing dynamic linking at a computing device. According to some embodiments, the techniques can involve receiving a request to perform a dynamic linking of a software application. The request can be issued in conjunction with installing the software application, launching the software application for a first time, and so on. In response to the request, a closure file can be generated based on different properties associated with the software application (e.g., environment variables, object files, etc.). Notably, the closure file is generated 'out-of-process' relative to the execution environment of the software application. Additionally, the techniques can involve caching the closure file such that the closure file is accessible to the software application. In turn, the software application can utilize the closure file at launch/execution times to reduce a number of dynamic linking operations that otherwise are required to take place using conventional approaches.

Techniques for performing dynamic linking

A system and method for dynamically loading object modules is described herein. In one embodiment, the method comprising loading a first set of instructions into a memory unit, wherein the first set of instructions includes an unresolved reference to a second set of instructions, and wherein the loading includes replacing the unresolved reference with an address of a third set of instructions. The method also includes executing instructions of the first set and executing instructions of the third set to determine the address of the second set. The method also includes loading instructions of the second set into the memory unit, after determining the address of the second set. Additionally, the method includes executing instructions of the second set.

System and method for dynamically loading object modules

A method and apparatus for manipulation of data in a computer-controlled display system. A user may select data from a first application program and drag it to an area on the computer system display representing a third application program. The first application program creates a series of formats into which the data may be provided and, in some instance, the data itself. Moreover, a second process appends to that list of formats a series of formats that it can provide the data in. Then, upon receipt of the list of formats and/or data of the first item, the third process can request the data in any of the formats from either the first or second processes, if required.

Method and apparatus for transferring data by type according to data

A method and apparatus for improved user interaction and feedback on a computer system display. Interapplication dragging upon a user interface display is provided allowing a user to select a first item in a first window and move that first item to a second window which is under control of second process. Feedback is provided in the second window under control of the second process if the second application program can accept the data. In addition, other improved user interface actions are described, such as improved selection feedback, improved navigation, and improved completion feedback.

Method and apparatus for improved feedback during manipulation of data

A method in a computer system enables the translation and opening of a document which was created by an application program no longer resident in the computer system. The method begins by identifying the file format of the target document, Subsequently, all computer resident applications capable of opening the document are identified and translation paths from the document to the accessible application programs are calculated. Each of the available application programs and corresponding translation paths are listed in order of fidelity, with an indicia identifying the preferred path. One of the translation paths is selected and the document is translated into the acceptable format. Following translation of the program, the application is launched and the newly translated document is opened.
