Providing a chain of tokenized error and state information for a call stack

A method, comprising:

• receiving a request with respect to an error chain;
• determining the type of operation requested by the request;
• initializing, if the requested operation is to initiate a new error chain, a new error chain based on context specific error state received together with the request, the new error chain being represented by a new error token;
• appending, if the requested operation is to append an existing error chain, an existing error chain represented by an error token received with the request using the context specific error state received with the request to generate an appended error chain represented by a new error token;
• and
• retrieving, if the requested operation is to retrieve an existing error chain, an existing error chain represented by an error token received with the request.

A system, comprising:

• a function module for performing a first function;
• an error handling mechanism for processing an error, including an error occurred during said performing the first function;
• and
• an error state appending mechanism for appending an error chain represented by an error token based on a context specific error state of the first function when said performing errorred to generate an appended error chain represented by a new error token.

An error chaining mechanism, comprising:

• an error buffer for hosting at least one error chain;
• an error chain management mechanism for managing, according to a request, the at least one error chain hosted in the error buffer, the at least one error chain being represented by corresponding error tokens;
• a request processing mechanism for processing the request to determine the requested operation to be performed on the at least one error chain;
• and
• an error token generation mechanism for generating an error token wherein the error token includes at least one of a fingerprint and an error buffer index.

A machine-accessible medium encoded with data, the data, when accessed, causing:

• performing a first function;
• processing, if said performing is in error, at least one error that is either contained in an error chain created based on at least one context specific error state and represented by an error token or occurred during said performing;
• returning, after said processing, either with a new error token representing a new error chain containing the at least one error or with an error status;
• and
• returning, if said performing yields no error, with a normal status.
