Delete support for browsing terms as XML.
The 'browse --xml' command has not worked with current versions of
xsltproc for quite some time, but we have not received any bug reports,
nor has anyone tried to fix it. We have a method for interactively
exploring a term in 'browse --web' so IMHO there is no need to keep
support for 'browse --xml'.

Ignore lines that start with `#' in sourced mdb scripts.
Estimated hours taken: 1 Branches: main Ignore lines that start with `#' in sourced mdb scripts. This is useful for documenting mdb scripts. Create a local copy of the mdbrc file so that we can test new mdb scripts in the test suite. NEWS: Mention the changes. configure.in: Create a copy of mdbrc.in in the tests directory and create an mdbrc from this file using different substitutions than those used for the mdbrc that will be installed. This is necessary so that we can use the local mdbrc file when running the tests. Previously if the mdbrc file was changed (for example a new alias was added), then we had to install it before testing. doc/user_guide.texi: Document the new behaviour of the source command. scripts/mdb_grep: scripts/mdb_open: scripts/mdb_track: Add comments to these mdb scripts. scripts/mdbrc.in: Use a different substitution variable for the location of mdb_doc, since for the test version of mdbrc mdb_doc will be in a different location to the other scripts. tests/Mmake.common: Get mdb to use the local mdbrc when invoked for the tests. Clean mdbrc and mdbrc.in. tests/debugger/Mercury.options: tests/debugger/Mmakefile: tests/debugger/scripts.exp: tests/debugger/scripts.inp: tests/debugger/scripts.m: Add a test case for the three existing mdb scripts. trace/mercury_trace_readline.c: trace/mercury_trace_readline.h: Rename MR_trace_readline_expand_args to MR_trace_readline_from_script and get it to ignore comment lines. trace/mercury_trace_internal.c: Adapt to changes in mercury_trace_readline.h. |

Add a new mdb command, 'shell', that allows users to execute shell commands
Estimated hours taken: 5 Branches: main Add a new mdb command, 'shell', that allows users to execute shell commands from within the debugger. Allow the user to give up to nine additional arguments to the 'source' command. Occurrences of the strings "$1" through "$9" in the sourced file are replaced by the corresponding additional arguments, allowing for parameterised scripts. Use the two new features mentioned above to add two more mdb commands: one to open a term, goal or exception in an external editor another command to perform a grep on a term, goal or exception (useful for seeing if a value occurs in a big map, for example). NEWS Mention the new commands. doc/mdb_categories: doc/user_guide.texi: Document the new commands. scripts/Mmakefile: scripts/mdb_open: scripts/mdb_vim: Add scripts for the new commands. scripts/mdbrc.in: Add aliases for the new shell, emacs, grep and vim commands. tests/debugger/completion.exp: tests/debugger/mdb_command_test.inp: Adjust for new commands. tests/debugger/save.exp: tests/debugger/save.exp2: Adjust for new commands.

Replace the "set" command of mdb with a bunch of commands: the `format',
Estimated hours taken: 16
Branches: main, release
Replace the "set" command of mdb with a bunch of commands: the `format',
`format_param', `list_context_lines', `list_path', `xml_browser_cmd',
`xml_tmp_filename', `fail_trace_counts', `pass_trace_counts' and
`max_io_actions' commands. Each of these set just one parameter
or one of set of closely related parameters.
Move all these commands, and some existing commands that set parameters
that were elsewhere, to the "parameter" command category.
Extend some of these commands so that if given no arguments, they report
the current values of the parameters they would otherwise set.
Replace the "set" commands of the mdb browser and of the declarative debugger
with a bunch of commands: "format", "depth", "size", "width", "lines",
"actions" and "params" (the last prints the current value of the parameters).
For each category of mdb commands, create files mercury_trace_cmd_<cat>.[ch],
and move the functions dealing with that category of commands there from
mercury_trace_internal.c. Give each of these new files a logical structure
that was sometimes missing from the relevant parts of mercury_trace_internal.c.
NEWS:
Mention these changes.

Document these changes.
doc/user_guide.texi:
Document these changes.
Fix an old documentation bug: you couldn't set listing paramaters
from a declarative debugger command.

browser/parse.m:
Update the browser command set along the lines at the top.
browser/declarative_user.m:
Update the declarative debugger command set along the lines at the top.

Update the predicate that generates mdb commands to save the persistent
state of the debugger to generate the new forms of parameter commands.
Move types and predicates for dealing with browser parameters from
browse.m to here, so that declarative_user.m can use them too.
browser/browse.m:
Delete the code moved to browser_info.m, and conform to the other
changes in the other modules.

Allow terms to be saved as XML in mdb and allow an XML browser to be invoked on
Estimated hours taken: 5 Branches: main Allow terms to be saved as XML in mdb and allow an XML browser to be invoked on browsable objects in mdb. The user can set two options which control where the XML is dumped and the command used to browse the XML. The defaults assume xsltproc and mozilla are installed. configure.in Check for mozilla/firefox and xsltproc so default the mdb XML browser command can be set if they are found. browser/browse.m Add a predicate to save a browser term as XML to a file. doc/user_guide.texi Document new --xml option for the mdb `browse' command.

This checkin has several major purposes, set out in the sections below,
Estimated hours taken: 240
This checkin has several major purposes, set out in the sections below,
all connected with the implementation of the new debugger command set.
DOCUMENT NEW DEBUG COMMAND SET
doc/user_guide.texi:
Add a new section on the debugger. The description of the commands
is complete, but some of the background sections, and the section
about how to build debuggable executables, are not yet done.
Update the documentation of the tracing options.
doc/generate_mdb_doc:
A new shell script that automatically converts some of the new
sections of the user guide into the online documentation of the
debugger.
doc/mdb_categories:
The fixed initial part of the online documentation.
doc/Mmakefile:
Add rules for creating mdb_doc, the file that is the online
documentation of the debugger, and for installing it together
with mdbrc.
Mmake.common.in:
Define INSTALL_DOC_DIR for doc/Mmakefile.
scripts/mdbrc.in:
A debugger command script that reads in the online documentation
and then defines some standard aliases.
configure.in:
Define the variable that scripts/mdb.in and scripts/mdbrc.in use
to find the right files, and get configure to perform the
substitutions.
configure.in:
scripts/mdb:
scripts/mdb.in:
Replace mdb with mdb.in. Mdb is now created during configuration
from mdb.in, filling in the name of the file that contains the default
debugger initialization commands.
util/info_to_mdb.c:
A program that does most of the work involved in automatically
converting user guide sections into online documentation.
(This couldn't easily be written in sh, because sh's read
command has no notion of pushback.)
util/Mmakefile:
Add info_to_mdb to the list of targets.
tools/bootcheck:
Make sure that the tests in tests/debugger are executed with an
initialization setup that is equivalent to what users will see
by default.
REORGANIZE TRACING OPTIONS
compiler/globals.m:
compiler/handle_options.m:
compiler/options.m:
compiler/trace.m:
Reorganize the handling of trace levels around the new options
--trace-internal, --trace-redo, and --trace-return.
compiler/*.m:
Use the new ways of getting at trace levels.
tests/hard_coded/typeclasses/Mmakefile:
s/--trace all/--trace deep/
SUPPORT RETRY
compiler/trace.m:
After every call to MR_trace(), emit code that checks whether it
should jump away, and if yes, performs the jump. This is used to
implement retry. (The debugger cannot execute the jump itself
because it is in the wrong C stack frame.)
compiler/llds.m:
compiler/continuation_info.m:
compiler/stack_layout.m:
Modify the data structures that record information about live
value at program points, to record the identity of each variable.
This is necessary for the implementation of the restart command,
since we do not want to confuse two distinct variables just because
they have the same name. For example, a variable whose name is X
and number is 5 is now recorded in the name array as "5:X".
Clean up the data structure a bit, so that we don't have to store
dummy names for values that are not variables.
compiler/*.m:
Minor changes to conform to the data structure changes.
runtime/mercury_stack_layout.h:
Redefine an existing macro to strip away the initial number: prefix
from the "name" of a variable (keeping its original function on
changed data), and add a new one to access the raw unstripped data.
runtime/mercury_init.h:
runtime/mercury_wrapper.h:
Update the prototype of MR_trace_{fake,real}, and the type of the
global that points to them.
runtime/mercury_layout_util.h:
Add an extra function, MR_get_register_number, for use by retry.
USE FIXED STACK SLOTS FOR TRACE INFO
compiler/code_gen.m:
compiler/code_info.m:
compiler/live_vars.m:
compiler/trace.m:
If execution tracing is enabled, reserve the first few stack slots
to hold the event number of the call event, the call number, the
call depth, the redo layout structure address (if generating redo
events) and the from_full flag at the time of call (if we are doing
shallow tracing). By allocating the first four of these to fixed stack
slots, the debugger knows where to look for them without having
to be told. It finds out the location of the fifth, if needed,
from a new slot in the proc layout structure. (It is not possible
to allocate all five to fixed stack slots without wasting stack space
in some cases.)
compiler/trace.m:
Remove from the call to MR_trace the parameters that are now in fixed
stack slots, since MR_trace can now look them up itself.
compiler/continuation_info.m:
compiler/stack_layout.m:
Add an extra field to the proc_layout_info. If the module is shallow
traced, this field says which stack slot holds the saved value of
MR_from_full. If it is not shallow traced, this field says that
there is no such stack slot.
runtime/mercury_stack_layout.h:
Add macros for accessing the fixed stack slots holding the event
number of the call event, the call number, the call depth, and,
at a redo event, the redo layout structure address.
Support the new field in proc layouts that gives the location of the
from-full flag (if any).
runtime/mercury_trace_base.[ch]:
trace/mercury_trace.[ch]:
Remove the call number and call depth arguments from MR_trace
and its avatars, since this info is now in fixed stack slots
in every procedure that can call MR_trace. This should reduce
the size of the executable significantly, since there are lots
of calls to MR_trace.
runtime/mercury_init.h:
runtime/mercury_wrapper.h:
Update the prototype of MR_trace_{fake,real}, and the type of the
global that points to them.
START NUMBERING FRAMEVARS FROM ONE
compiler/code_info.m:
compiler/live_vars.m:
compiler/llds_out.m:
compiler/trace.m:
Start numbering framevars from 1 internally to the compiler;
the runtime already starts from 1. This simplifies several tasks.
ADD REDO EVENTS
compiler/trace.m:
compiler/code_gen.m:
Before the code that executes "succeed()", emit code to push a
a temp nondet frame whose redoip points to a label in the runtime
that calls MR_trace for a REDO event and then fails, provided
--trace-redo is set.
compiler/llds.m:
Add a new code address constant, do_trace_redo_fail, which stands
for the address in the trace system to which calls MR_trace for
the redo event and then fails.
compiler/trace.m:
compiler/llds_out.m:
Provided we are doing redo tracing, fill in the slot that holds
the layout information for the REDO event.
compiler/*.m:
Minor changes to conform to handle the new code address constant.
browser/debugger_interface.m:
Add redo to trace_port_type.
runtime/mercury_trace_base.[ch]:
Add a C module containing the code that calls MR_trace for REDO
events.
ENSURE THAT INPUT ARGUMENTS ARE ALWAYS VISIBLE
compiler/trace.m:
When generating the set of live variables at internal ports,
the variables that are in the pre-death set of the goal into which
we are entering may not be available. However, the variables in the
pre-death set that are also in the resume vars set will be available,
so now include info about them in the layout structure for the event.
Since with tracing the non-clobbered input args are in all resume vars
sets, this ensures that these input args will be available from all
internal events.
compiler/code_info.m:
Export a previously internal predicate (current_resume_point_vars)
to make this possible.
BUG FIX: WANT RETURN LAYOUTS
compiler/globals.m:
compiler/call_gen.m:
compiler/code_info.m:
compiler/mercury_compile.m:
Add a new pred globals__want_return_layouts, which says whether the
compiler should generate layout structures for call returns. This pred
centralizes the several previous copies of the test. One of those
copies (the one in call_gen) was faulty, leading to a bug: in the
presence of execution tracing but the absence of accurate gc,
information about the variables that are live at the call return
wasn't being gathered properly.
BUG FIX: #include mercury_trace_base.h
compiler/llds_out.m:
#include mercury_trace_base.h, not mercury_trace.h, since now
mercury_trace_base.h defines everything directly accessible from
modules compiled with tracing.
RECAST MERCURY_TRACE_UTIL AS MERCURY_LAYOUT_UTIL
runtime/mercury_trace_util.[ch]:
runtime/mercury_layout_util.[ch]:
Rename this module from trace_util to layout_util, since it is also
used by the native garbage collector. Remove "trace" from the names
of functions.
Get rid of the global variable MR_saved_regs, and instead thread
a pointer to this data structure through the relevant functions
as an extra argument.
Add a lot more documentation in the header file.
runtime/Mmakefile:
Reflect the module rename.
runtime/*.c:
Refer to the new module.
DELETE EASY-TO-MISUSE MACROS
runtime/mercury_stacks.h:
Delete the based_framevar and based_detstackvar macros, since their
continued use can lead to off-by-one errors, and the saved_framevar
and saved_detstackvar macros, since they are no longer used.
runtime/*.c
Update any references to any macros removed from mercury_stacks.h.
MISC RUNTIME CHANGES
runtime/mercury_trace_base.[ch]:
trace/mercury_trace*.[ch]:
Make typedef'd names conform to the naming convention.
Make MR_trace_call_{seqno,depth} consistently Unsigned, rather than
sometimes Word and sometimes Unsigned.
FIX BUG: MAKE THE DEBUGGER PRINT TO STDOUT, NOT THE CURRENT STREAM
library/io.m:
Export to C code the predicates that return the identities and types
of stdin, stdout and stderr, as well as io__print/[34].
library/std_util.m:
Export to C code a predicate that returns the type_info for the
type stdutil:type_info. This type_info is required if C code
wants to invoke make_permanent on any type_info structure,
as the debugger does.
runtime/mercury_init.h:
Add extern declarations for the C functions now exported from io.m.
runtime/mercury_wrapper.[ch]:
Add new global variables to hold the addresses of these C functions.
runtime/mercury_layout_util.c:
Use indirect calls through these global variables to print Mercury
values, instead of lower-level code.
util/mkinit.c:
Assign the addresses of the functions exported from io.m to the
global variables defined in mercury_wrapper.h.
BUG FIX: STACK TRACE FUNCTIONS DEPEND ON THE LABEL TABLE
runtime/mercury_stack_trace.c:
On entry to any of the functions exported from this module,
ensure that the label table is loaded by calling do_init_modules.
Without a filled-in label table, the stack trace will not be able to
find any stack layout info.
BUG FIX: REMOVE BROWSER/*.C
configure.in:
When removing .c files generated by the C compiler, remove those
in the browser directory as well as the compiler, library and
profiler directories.
IMPLEMENT NEW DEBUGGER COMMAND SET
runtime/mercury_stack_trace.[ch]:
Factor out the code that prints the id of a procedure into a function
of its own, so that it can also be used from the debugger, ensuring
appearance commonality.
Add more documentation in the header file.
trace/mercury_trace_internal.c:
Implement the proposed command set. Command names are now words,
and several commands now have options allowing the user to override
the default print level or strictness of the command, or the
invocation conditions or action of a break point. Allows control
over command echoing and the scrolling of sequences of event reports.
Supports aliases, command file sourcing etc. Implements the retry
command, using the info in the fixed stack slots.
trace/mercury_trace.[ch]:
Extend the trace controls to support the new functionalities
required by the new debugger language, which are print levels,
variable-strictness commands, a more flexible finish command,
and the retry command.
Pass the command structure to MR_trace_event_report, since
the user can now forcibly terminate the scrolling of reports.
trace/mercury_trace_alias.[ch]:
New module to manage aliases for the debugger.
trace/mercury_trace_help.[ch]:
New module to interface to browser/help.m.
trace/mercury_trace_spy.[ch]:
New module to manage break points. The test of whether an event
matches a break point is now much more efficient than before.
The new module also allows several breakpoints with different
actions and different invocation conditions (e.g. all ports,
entry port, interface ports or specific (possibly internal) port)
to be defined on the same procedure.
trace/mercury_trace_tables.[ch]:
New module to manage a table of the debuggable modules, in which
each such module is linked to the list of the layouts of all the
procedures defined in that module. This information allows the
debugger to turn the name of a predicate/function (possibly together
with its arity and mode number) into the procedure layout structure
required by the spy point module. Eventually it may also be useful
in supplying lists of identifiers for command line completion.
Modules for which no stack layout information is available will
not be included in the table, since do_init_modules will not
register any labels for them in the label table.
trace/Mmakefile:
Mention the new files.
runtime/mercury_array_macros.h:
A new file holding macros that can be useful in more than one module.
runtime/Mmakefile:
Mention the new file.
runtime/mercury_conf.h.in:
Mention a new configuration macro, MR_CANNOT_USE_STRUCTURE_ASSIGNMENT,
used by runtime/mercury_array_macros.h.
configure.in:
Find out whether we need to define MR_CANNOT_USE_STRUCTURE_ASSIGNMENT.
ADD TRACE DEPTH HISTOGRAMS
runtime/mercury_conf_param.h:
Document MR_TRACE_HISTOGRAM.
runtime/mercury_trace_base.[ch]:
Define the data structures for the histogram, and print the histogram
when a traced program exits if MR_TRACE_HISTOGRAM is set.
trace/mercury_trace.[ch]:
If MR_TRACE_HISTOGRAM is defined, record a count of the number of
events at each depth. This information can help us evaluate space-time
tradeoffs.
FACTOR OUT SHELL CODE HANDLING GRADE IMPLICATIONS
scripts/final_grade_options.sh-subr:
A new file to contain any code that implements implications between
grade flags; currently implements the implication debug -> use trail.
scripts/mgnuc.in:
scripts/ml.in:
Replace the code that is now in final_grade_options.sh-subr with
an inclusion of final_grade_options.sh-subr.
configure.in:
Handle final_grade_options.sh-subr as {init,parse}_grade_options.sh-subr
are handled.
SIMPLIFY THE MAINTAINANCE OF CONSISTENCY BETWEEN DEBUGGER CODE AND DOCUMENTATION
doc/Mmakefile:
Add rules for creating mdb_command_list, a C code fragment
that can included manually in trace/mercury_trace_internal.c
to supply the list of valid commands, and mdb_command_test.inp,
which is a list of invalid invocations of debugger commands,
which tests whether the help message for such invocations
can be located as expected.
doc/generate_mdb_command_list:
doc/generate_mdb_command_test:
Awk scripts to create mdb_command_list and mdb_command_test.inp
respectively from mdb_doc.
tools/bootcheck:
Copy mdb_command_test.inp from doc to tests/debugger.
tests/debugger/Mmakefile:
Add a new test that checks whether we get an internal error, unable
to locate the right help node, for each invalid command invocation in
mdb_command_test.inp.
UPDATE TEST CASES
tests/debugger/Mmakefile:
Reenable queens. Conform to the new set of options.
tests/debugger/*.inp:
tests/debugger/*.exp:
Update the inputs and expected outputs of the debugger test cases
to use the new command set and output formats.
