Time travel source code debugger incorporating asynchronous collaboration

A method, implemented on a computer that includes one or more processors, of asynchronous collaborative debugging of a debuggee application having source code associated therewith, the method comprising:

• generating and transmitting, on a first computer, a share request to one or more participants of a debugging session;
• generating and sharing, on said first computer, one or more point in time links with participants in the debugging session, each point in time link indicating a specific location in the source code and execution context including a specific point in time in the execution of the source code;
• upon acceptance of said share request at a second computer, downloading current debugging session state previously captured by said first computer and utilizing it immediately for debugging while contemporaneously downloading a dump file captured by said first computer;
• rebuilding, on said second computer, a memory delta buffer from the captured dump file once obtained, ceasing using the captured current debugging session state, and utilizing the captured dump file and rebuilt memory delta buffer for the debugging session;
• and
• reconstructing one or more variables, on said second computer, by traversing backwards through said memory delta buffer from a memory delta buffer index indicated by said point in time link whereby variables found in said memory delta buffer are set equal to values stored therein.

A method, implemented on a computer that includes one or more processors, of asynchronous collaborative debugging of a debuggee application having source code associated therewith, the method comprising:

• capturing and uploading to a cloud debugger, on a first computer, a current debugging session state including a memory delta buffer, process dump file, and source code if not already present thereon;
• generating, on said first computer, a share request to one or more participants of a debugging session;
• upon accepting the share request on a second computer, opening an additional view for the added participant in a cloud debugger;
• downloading said current debugging session state including said memory delta buffer, said process dump file, and said source code previously stored on the cloud debugger, if not already present on said second computer, in the additional view opened on said second computer;
• providing, by said debugging session, an asynchronous chat service for all participants of the debugging session, whereby participants are able to transmit text messages between each other to facilitate said debugging session;
• and
• reconstructing, on said second computer, one or more variables by traversing backwards through said memory delta buffer whereby variables found in said memory delta buffer are set equal to values stored therein.

A computer program product for asynchronous collaborative debugging of a debuggee application having source code associated therewith, the computer program product disposed upon a computer readable storage medium, the computer program product comprising computer program instructions that, when executed by a computer program computer, cause the computer to carry out the steps of:

• capturing both a dump file and a current debugging session state on a first computer, said dump file and said current debugging session state sent to at least one of a cloud debugger, and an on-premise production debugger;
• generating and transmitting, on said first computer, a collaboration request message to one or more participants of a debugging session which includes a debug session link to said captured dump file and said current debugging session state;
• generating and sharing one or more point in time links with participants in the debugging session, each point in time link indicating a specific location in the source code and execution context including a specific point in time in the execution of the source code;
• in response to the collaboration request message and utilizing said debug session link, obtaining, on a second computer, the current debugging session state captured previously on said first computer and utilizing it immediately for debugging while contemporaneously obtaining the dump file captured previously on said first computer;
• obtaining on said second computer a memory delta buffer ceasing using the captured current debugging session state, and utilizing the captured dump file and memory delta buffer for the debugging session;
• and
• reconstructing one or more variables, on said second computer, by traversing backwards through said memory delta buffer from a memory delta buffer index indicated by said point in time link whereby variables found in said memory delta buffer are set equal to values stored therein.
