Estimated hours taken: 24 Add support to the Mercury tracer for interacting with an external Opium-style debugger via a socket. TODO: currently there is no way for the debugger to specify constraints on the arguments for a `forward_move' query. The current code for doing that doesn't work. (However, the reporting of arguments to the debugger for an `output_current' query works fine.) runtime/mercury_trace.c: Add code to MR_trace() to open a socket connection to an external debugger, and to process requests from that debugger, and send responses back. runtime/mercury_trace.h: runtime/mercury_wrapper.c: Call MR_trace_end() from mercury_runtime_terminate() so that the external debugger gets notified when the program does a (normal) exit. runtime/mercury_stack_layout.h: Fix a bug where the structures here did not match the output produced by compiler/stack_layout.m. library/debugger_interface.m: New file. Declares the Mercury types used for the debugger socket interface and defines support routines used by runtime/mercury_trace.c. library/io.m: runtime/mercury_types.h: Move the definition of MercuryFile from library/io.m to runtime/mercury_types.h, for use by runtime/mercury_trace.c. library/io.m: When printing out values of type `c_pointer', print out the "<<c_pointer>>" string in single quotes, to ensure that it has valid syntax for a Prolog or Mercury term. This is necessary because otherwise c_pointers in procedure arguments could lead to the Mercury process sending a syntactically invalid term down the socket to the debugger, which would then be unable to parse it. library/library.m: Add reference to debugger_interface.m, so that it gets include in libmercury.a. doc/Mmakefile: Make sure that the library/debugger_interface.m does *not* get included in the Mercury library reference manual. runtime/mercury_wrapper.h: runtime/mercury_wrapper.c: runtime/mercury_init.h: util/mkinit.c: Declare, define, and initialize pointers to the C functions exported by library/debugger_interface.m. (This is to avoid having a circular dependency where the runtime depends on the library.) compiler/notes/authors.html: Add Erwan Jahier.

Each source file should contain a comment indicating the

main author(s) of that file. This is done not out of vanity,
|
|
but so that you know who to blame ;-). If you find any
|
|
of the source code difficult to understand or insufficiently
|
|
commented, complain to the author.
