Require warning/info messages to specify an option.
The objective of this step is two-fold:
- to fix --inhibit-warnings, making it shut up all warning
and informational messages; and
- to ensure that it *stays* fixed, even when after new diagnostics
are added.
As part of this fix, this diff adds a whole bunch of new warning
options, in order to control the warnings that previously were
not controlled by any option. (There was no need for new
informational options.)
As it happens, we have long used severity_informational for messages
that did not report any information about the code being compiled,
but to report actions that the compiler was taking. Create a new
option category, oc_report, for the new options that now control
those diagnostics.
---------------------
compiler/error_spec.m:
Change severity_warning and severity_informational to take an option
as as argument. The semantics is that the diagnostic in which
the severity occurs is conditional on that option, meaning that
it is printed only if that option is set to "yes".
Delete the severity_conditional function symbol from the severity
type, since the mechanism just above handles its only use case.
Define subtypes to represent error_specs in a standard form.
compiler/error_sort.m:
Provide operations to convert error specs into their standard form.
Make the sorting operation itself operate on the standard form.
compiler/write_error_spec.m:
Convert error_specs to standard form before writing them out,
in order to avoid duplicating the code for their standardization.
Change the code that writes out error_specs to operate on the
standard form. Implement the test implicit in the warning and
and informational severities in this code.
compiler/error_util.m:
compiler/compiler_util.m:
Delete operations that do not make sense with the new severity type.
---------------------
compiler/options.m:
Add new options to control all the previously-uncontrolled
warning and informational messages.
NEWS.md:
Announce the *public* new options.
compiler/option_categories.m:
compiler/print_help.m:
Add the new option category, and fake-include it in the help text
and the user guide. (The inclusion is fake because none of the
options in the new category are user visible, meaning the section
containing them is not visible either.)
---------------------
compiler/det_infer_goal.m:
Start a severity warning diagnostic with "Warning:"
instead of "Error:".
compiler/mark_trace_goals.m:
Fix an incorrect error message.
compiler/purity.m:
Replace a correct/incorrect color pair with two inconsistent colors,
because there is a reasonable probability of each one being right.

Shorten function symbols in error_specs.
compiler/error_spec.m:
Replace simplest_spec with spec, and simplest_no_context_spec with
no_ctxt_spec. These are now the most frequently used function symbols
to create error specs, so their name should not make them out to be
the exception.
Replace simplest_msg with msg, and simplest_no_context_msg with
no_ctxt_msg for the same reason.
Abbreviate some of the long phase names.
compiler/*.m:
Conform to the changes above. Most of these changes were done by a script,
with minor manual tidying up, which consisted mostly of fitting code
constructing error specs onto fewer lines than before.

Stop using .tmp files when generating .intN files.
compiler/write_module_interface_files.m:
Instead of
- writing out the new version of a .intN file to module.intN.tmp,
- comparing that file with module.intN, and
- renaming module.intN.tmp to module.intN if they differ,
we now
- read in the old .intN file to a string
- convert the new parse tree for .intN to a string
- write out the string form of the new parse tree to module.intN
if they differ.
The logic is bit more complex in the presence of smart recompilation
(in both the old new algorithms) but not by much.
The new algorithm requires significantly fewer system calls than the old.
compiler/comp_unit_interface.m:
Don't create a name for .intN.tmp files, since they are not needed anymore.
compiler/module_cmds.m:
Reorder the predicates that copy files putting the most basic predicate
last, so that calls go from earlier predicates to later predicates.
compiler/parse_module.m:
Delete unneeded IO state args from the parse_intN_file predicates.
compiler/parse_tree_out.m:
Carve output_parse_tree_string out of the existing
output_some_parse_tree predicate which also *constructed* that parse tree.
This capability is needed by new code in write_module_interface_files.m,
which wants to perform other operations on the string forms of parse trees
before writing them out.

Fix more C# test case failures in tests/invalid*.
compiler/options.m:
doc/user_guide.texi:
Add a new developer-only option, --std-int-file-not-written-msgs,
which, if specified, calls for the "file not written" messages
we generate when we want to write interface files but can't
to be written out in a standard form that deletes the directory
path component from the names of the files not written out.
In the long term, it is less work to add this option once
than to add a separate .err_exp file for each affected test case.
compiler/write_module_interface_files.m:
Obey the new option.
tests/invalid/ee_invalid.m:
Add C# and Java foreign_types next to the C foreign_type.
tests/invalid/erroneous_throw_promise.m:

compiler/write_module_interface_files.m:
compiler/comp_unit_interface.m:
Move the predicates that generate the parse trees of interface files
from write_module_interface_files.m to comp_unit_interface.m.
Move the types they need with them, and document them.
Rename the predicates involved to make clear whether they generate
parse trees, write them out, or both.
In comp_unit_interface.m keep private the previously exported predicates,
because their only callers are the moved predicates, so all calls them
are now local to the module.

Generate and write parse_tree_intNs in separate preds.
compiler/write_module_interface_files.m:
Put the code that writes out parse_tree_intNs in separate predicates
from the code that generates them.
This separation is useful in situations in which
- we need to generate several .intN files as fast as possible, and
- later operations will need access to the contents of those files.
With the current setup, we can call e.g. write_short_interface_file_int3
on several parse_tree_module_srcs in parallel, but this comes at the cost
of each worker process building up only its own have_parse_tree_maps
"database" of parse trees. This means if worker process A generates
an interface file, another worker process B will need to read that
interface file to get access to its contents.
With the setup created by this diff, we can generate all the parse trees
for the interface files in the main process, keeping *all* their parse
trees in its have_parse_tree_maps structure, and hand off each parse tree
as it is constructed to a worker process for writing out.

Give an initial module_baggage to grab_modules.m.
compiler/grab_modules.m:
grab_{qual,unqual}_imported_modules_*, the two main predicates
of this module, have for a while now taken as input both a
parse_tree_module_src, and several separate arguments each describing
part of the origin of that parse_tree_module_src. They then created
a new module_baggage structure, filling some of its fields using
those arguments, but filling other fields with default values,
which were no more than guesses at what the right value might be.
This has obviously worked, but it could work only because
the guessed-at fields are either not used or were guessed well.
However, this may change in the future. After this diff, we now require
the caller to pass to these predicates a fully-and-correctly-filled-in
module_baggage structure instead, which guards against that
possibility, and leads to cleaner and more understandable code
to boot.
We do throw away any errors in the initial module_baggage
in order to prevent parts of the compiler that aren't set up
to handle any errors there from causing additional test failures
in C# (and probably Java) grades. This preserves old behavior,
at least for now.
compiler/write_module_interface_files.m:
Make the versions of write_private_interface_file_int0 and
write_interface_file_int1_int2 that took a burdened_module
as an argument the *only* versions of those operations,
since the burdened_module contains the module_baggage structure
we now want to pass to grab_modules.m.
Replace the parse_tree_module_src argument of
write_short_interface_file_int3 with a burdened_module.
This is only for "cultural compatibility" with the neighboring
predicates; unlike those two, this predicate does not need access
to the module_baggage.

Use ProgressStreams, not ErrorStreams, to write out error messages about
any failures of filesystem operations. These are not appropriate to put
into a module's .err file, since they are not about an error in the
Mercury code of the module.
compiler/globals.m:

compiler/passes_aux.m:

versions of the progress-message-writing predicates that didn't get
the progress stream from their caller.
compiler/*.m:

as mentioned at the top of log message.
In a few places, don't write out error_specs to ErrorStream,
returning it to be printed by our caller, or its caller etc instead.
In some of those places, this allowed the deletion an existing
ErrorStream argument.
Given that get_{progress,error}_output_stream took a ModuleName input,
deleting some of the calls to those predicates left ModuleName unused.

Make --generate-dependencies-ints more practical.
scripts/Mmake.rules:
Add a rule for the pattern target %.depend_ints which invokes mmc
with --generate-dependencies-ints, just as %.depend invokes mmc
with --generate-dependencies.
Document the reason why this addition requires yet more code duplication.
scripts/Mmake.vars.in:
Add the make variable definitions needed by the new code in Mmake.rules.
compiler/mercury_compile_main.m:
Make it practical to use --generate-dependencies-ints in a multi-directory
project like the Mercury implementation, in which some directories
may use --generate-dependencies-ints as the target of "mmake depend",
while other directories, which come earlier in the build process,
still do "mmake depend" using just --generate-dependencies.
In such cases, mmc --generate-dependencies-ints in the later directory
may fail to generate .int0, .int or .int2 files simply because
the .int3 file of a module they import (from an earlier directory
in which "mmake depend" uses just --generate-dependencies) hasn't been
made yet. (This is what would happen if someone executed "mmake depend"
at the top level in a freshly checked out workspace.)
The practical fix is to simply report this fix using an error message
that still allows the compiler to exit with an exit status that
indicates success.
Most of the rest of this diff is there to make this possible.
compiler/error_spec.m:
Add a new phase, phase_find_files, that specifically indicates
that we couldn't read a file because we couldn't find it.
Give it a string argument naming the file, to allow mercury_compile_main.m
to replace several error_specs that each report not being able to find
one file with a single error_spec that reports not being able to find
many files.
Add a utility function for use by mercury_compile_main.m to construct
that error message.
Add another new phase, phase_make_int, that indicates a problem
we discovered in the code of a Mercury source file while trying
to decide what should got into one of the that module's interface files.
compiler/parse_error.m:
Here also use separate function symbols in the fatal_module_read_error
type for the situations "couldn't find a file" and "couldn't read a file".
Update the predicates constructing error_specs to handle this distinction
(which the callers make using the new function symbol in the above type).

Add new option --generate-dependencies-ints.
This new option extends --generate-dependencies to take advantage of the
opportunity afforded by the fact that "mmc --generate-dependencies prog.m"
reads in every Mercury source file in the current directory that is
part of "prog". It does this by
- generating the .int3 file of all local-directory modules of the program;
- generating the .int0 file for each these modules that has submodules;
- generating the .int and .int2 files of all local-directory modules
of the program.
Normally, the process of creating .int0, .int and .int3 files would
need to read in .int0 and .int3 files, but in every one of these cases,
we have just written out those files, so simply holding onto their
parse trees, we can skip this step. On my laptop, on a directory
containing library/*.m, mdbcomp/*.m and compiler/*.m, generating
the dependencies and generating all the .int3/.int0/.int/.int2 files
takes just over 25 seconds. Using the new option, the same process
takes less than 10 seconds.
compiler/options.m:
Add the new option.
compiler/op_mode.m:
Add a new variant of the existing op_mode for --generate-dependencies,
which we select in the presence of the new option.
compiler/mercury_compile_main.m:
Implement the new op_mode.
Fix an old issue, which is that "mmc --make-private-interface x.m"
generated a .int0 file for *every* module in x.m, even the modules
that don't have any submodules.
compiler/deps_map.m:
The code implementing the new option needs to know which modules
of the program are in the current directory. The deps_map structure
built by the code shared with the implementation of --generate-dependencies
has not needed that info until now, so add a new field to the deps
structure of each module to provide this info.
compiler/generate_dep_d_files.m:
Return the deps_map created by the code that implements both
--generate-dependencies and the new option to mercury_compile_main.m.
compiler/write_module_interface_files.m:
Add a flag to the predicates that first construct the parse trees of,
and then write out, .int3/.int0/.int/.int2 files, that
mercury_compile_main.m can use to tell them to record the parse trees
in the have read module maps.
Add new variants of two of those predicates that take some of their
arguments from burdened_module structures, since that is the form
in which mercury_compile_main.m has that info.
compiler/module_baggage.m:
The predicates in write_module_interface_files.m that generate
.int0/.int/.int2 files take an argument that should be the timestamp
of the source file they are being derived from, if that timestamp
is needed for smart recompilation. Until now, we only ever invoked
those predicates when we have just read in the source file,
and this timestamp was readily available. The code implementing
the new option needs to store this info for a short time, and
the module baggage is the obvious place to store it, so add this field
to the baggage.
compiler/error_spec.m:
An invocation of the compiler with new option may report errors that
prevent the construction of interface files for several modules.
The new code in mercury_compile.m prints the error_specs that have
contexts in the order of those contexts, but we want to print
the messages without contexts (which in this case report that
certain files could not be written or copied) to have a useful
order too. Make this possible by allowing the invisible pieces
we use for ordering to specify that order via a string (in this case,
the name of the file that e.g. could not be written), rather than
the only previous option, an integer.

error_specs being compared actually *have* contexts.

Eliminate calls to io.output_stream in read_modules.m.
compiler/read_modules.m:
When invoked to read a file specified by file name (as opposed to
by module name), the code of this module wrote out progress messages
to the current output stream, as returned by io.output_stream.
Fix this by consistently requiring the ancestors of the predicates involved
to pass an explicit stream to write progress messages to.
The interfaces of some of the exported predicates allowed their callers
to either pass a progress stream or not; if they didn't, this prevented
the generation of any progress messages with -v and the generation of
any statistics with -S. Most callers did specify the progress stream;
the main parts of the compiler that did not were
- the code that read the old versions of interface files in order to see
whether the new version was identical to it, or not, and
- the intermodule analysis framework.
This diff requires callers to always pass a progress stream, because
we *always* want to write out any error messages about nonexistent
or unreadable files, and we don't want to write these to an implicitly
specified file. We *could* add a parameter to the affected predicates
to shut up progress messages and statistics for use at the call sites
that previously passed us "no" as the maybe progress stream argument,
but I see no reason why one wouldn't want -v and -S to work as usual
in these above circumstances. If anyone ever finds such a reason,
there is a simpler fix anyway: turning off -v and -S in the globals
passed along next to the progress stream.
compiler/module_cmds.m:
Stop requiring an error stream and as well as a progress stream
when touching files. If the two streams were ever different, the
output would have looked strange, as the error message would NOT follow
the progress message announcing the operation that failed.

Replace Mkdir parameters with predicate versions.
compiler/file_names.m:
Split module_name_to_file_name into three versions.
- One corresponds to the old predicate's operation with do_not_create_dirs,
- one corresponds to the old predicate's operation with do_create_dirs, and
- one just returns the directory path, and lets the caller make those
directories if it wants to, using procedures that we now export.
Do the same for module_name_to_lib_file_name.
Do not do the same for fact_table_file_name, which has too few callers
to make it worthwhile.
The point is that the versions that do not create any dirs should NOT
need to take I/O state pairs as arguments, once we take ext_src

Start using the new code in file_names.m.
compiler/file_names.m:
Change the argument vectors of the predicates that compute filenames
by taking *two* arguments to specify the extension: adding an argument
value of the "newext" type right after the old "ext" type. To make this
possible, export the newext type.
By default, use the new argument to do every filename computation twice,
with the old and new algorithms, throwing an exception if their results
differ. (There is no easy way to test whether the "make-any-needed-dirs"
part was done the same way, but this is reasonably easy to check
visually in the code.)
In case an exception does get thrown, this can be suppressed (hopefully
after the exception being reported) by setting the environment variable
"NO_EXT_CHECKS" to any value.
Add representations of "get the value of this extension from this option"
style extensions to the newext type, for each of the options that the
compiler uses this way. The one exception is java_object_file_extension,
which was used in this way, but which had no code handling it in
file_names.m.
Add a representation of ".$(EXT_FOR_PIC_OBJECTS)" as a value
to the newext type.
Shorten some function symbol names in the newext type and its components,
to make them easier to fit without excessive line lengths in the modules
listed below.

Split up error_util.m into five modules.
compiler/error_spec.m:
This new module contains the part of the old error_util.m that defines
the error_spec type, and some functions that can help construct pieces
of error_specs. Most modules of the compiler that deal with errors
will need to import only this part of the old error_util.m.
This change also renames the format_component type to format_piece,
which matches our long-standing naming convention for variables containing
(lists of) values of this type.
compiler/write_error_spec.m:
This new module contains the part of the old error_util.m that
writes out error specs, and converts them to strings.
This diff marks as obsolete the versions of predicates that
write out error specs to the current output stream, without
*explicitly* specifying the intended stream.
compiler/error_sort.m:
This new module contains the part of the old error_util.m that
sorts lists of error specs and error msgs.
compiler/error_type_util.m:
This new module contains the part of the old error_util.m that
convert types to format_pieces that generate readable output.
compiler/parse_tree.m:

Don't return dummy parse_trees for missing files.
The predicates that read a Mercury source, interface or optimization file
used to return four things:
- the name of the file (for callers who specified only a module name),
- the timestamp, if requested and available,
- a parse tree, and
- a representation of any errors (sets of error categories, and error_specs).
However, these four things were not independent. Some combinations of their
values were not allowed, but (a) there was no documentation of what these
combinations were, and (b) code that processed these four things had to be
prepared to handle illegal as well as legal combinations.
This diff makes these predicates return only one result, which contains
- all four of the above things, when the file could be opened, but
- only the file name and a representation of the error if the file
could not be opened,
- only the file name and a representation of *no* errors, if the caller
asked the predicate to read the file only if its timestamp did not match
a specified value, and it does match that value.
We use a somewhat modified version of an existing type, have_read_module,
for this. It is modified both by including information that its users
now need that they did not need before, and shortening the names of its
function symbols, which now occur in many more places than before.
compiler/read_modules.m:
Make the change to the output arguments described above.
Making this change requires having the affected predicates deal with
the case where we either cannot find or cannot open the relevant file.
(The two are effectively the same thing in this module, since we search
by attempting to open.) Passing that task off to parse_modules.m
was always inelegant.
Simplify the have_read_module_map type by making the key always
be a module_name. We deleted the only use of have_read_module_maps
with another kind of key a while ago.
Delete some no-longer-needed predicates.
compiler/parse_module.m:
Delete the code dealing with the absence of a file stream to parse.
Replace code that used to construct dummy parse trees with code
that simply returns *no* parse tree if the file could be opened
but could not be read, or if its timestamp indicated that reading it
would have been redundant.
Delete some utility predicates moved to parse_error.m, so that
read_modules.m could also use them.
Fix comment rot.
compiler/parse_error.m:
Add some utility predicates for use by read_modules.m and parse_module.m.

Change them to return just the parts of the parse tree that the
caller was interested in, which was usually a tiny part, and which
can be constructed trivially even when we don't have a parse tree.
Delete an unneeded type.
compiler/recompilation.check.m:
Conform to the changes above.
Represent the operations we need to test version numbers in interface files
as a typeclass, and rewrite the checking operation in terms of that
typeclass, with one instance for each kind of interface file.

uses in read_modules.m.
tests/recompilation/two_module_debug:
Extend this script to help deal with problems in all stages of the
execution of a test case, since that was required while debugging
this diff.
Document which parts of this script correspond to which parts of

once instead of three times.
Specify whether a recompilation test is expected to succeed or fail
directly, using alternatives that model a bespoke type, instead

Separate fatal and nonfatal module reading errors, ...
... and bundle sets of error kinds and their associated lists of error_specs
into a single structure.
compiler/parse_error.m:
Use separate types to represent fatal errors and nonfatal errors,
because those two kinds of errors are often treated differently.
Change the read_module_errors type, which used to be just a set of errors,
to being a set of fatal errors, a set of nonfatal errors, the error
message for each, and error messages for warnings. This preserves

Treat the failure of reading the contents of a file as a fatal error.
Previously, we treated it as a nonfatal error.
Delete some fields from types when those field were always set to the
same value, and therefore contained no useful information.

Use var_tables in lco.m, and when dumping goals.
Since this is the first converted module that dumps out goals when
debugging trace flags are enabled, this required generalizing the code
that does that, to take either varsets or var_tables as a means of
specifying the names of variables. We do this via a new type,
var_name_source, which contains either a varset or a var_table.
Almost all of this diff is there to implement this generalization.
A large part of it affects code in the parse_tree package that we use
to write out the parts of HLDS goals that are defined by types defined
in that package. Since we want to avoid making any part of the parse_tree
package dependent on the hlds package, this required defining the
var_name_source type in the parse_tree package, which in turn requires
var_table.m to be in that same package.
compiler/lco.m:
Convert this module to use var_tables instead of varsets and vartypes.
compiler/var_table.m:
Move this module from the hlds package to the parse_tree package.
To make this, possible, move the parts that required access to the HLDS
to hlds_pred.m, from where it was usually invoked.
Export some utility predicates to allow the moved code to work
in hlds_pred.m without access to the actual definition of the
var_table type.
Define the var_name_source type.
Add some utility functions for use by code writing out variable names.
compiler/hlds_pred.m:
Add the code moved from var_table.m.
compiler/vartypes.m:
Move this module from the hlds package to the parse_tree package,
for symmetry with var_table.m. It did not depend on being in hlds
in any way.
compiler/hlds.m:
compiler/parse_tree.m:
Move vartypes.m and var_table.m from the hlds package
to the parse_tree package.
compiler/hlds_out_goal.m:
Change all the predicates in this module to take a var_name_source
instead of a prog_varset.
Fix some comments.
compiler/hlds_out_util.m:
Change some of the predicates in this module (those called from
hlds_out_goal.m) to take a var_name_source instead of a prog_varset.
compiler/parse_tree_out_term.m:
Provide variants of some existing predicates and functions that take
var_name_sources instead of varsets. The code of the copies
duplicates the logic of the originals, though I hope that this
duplication can be done away with at the end of the transition.
(The best solution would be to use a typeclass with methods
that convert vars to their names, but we would want to ensure
that the compiler can specialize all the affected predicates
and functions to the two instances of this typeclass, which is
something that we cannot do yet. In the meantime, the lack of
any generalization in the old versions preserves their performance.)
tools/sort_imports:
tools/filter_sort_imports:
A new tool that automatically sorts any occurrences of consecutive
":- import_module" declarations in the named files. The sorting is done
in filter_sort_imports; sort_imports loops over the named files.
After automatically replacing all occurrences of hlds.{vartypes,var_table}
in import_module declarations with their parse_tree versions, the updated
import_module declarations were usually out of order with respect to
their neighbours. I used this script to fix that, and some earlier
out-of-order imports.

Carve io.file.m out of io.m.
library/io.file.m:
library/io.m:
Move two sections of io.m, the "file handling predicates" section
and the "handling temporary files" section to the new submodule io.file.m.
Leave behind in io.m "forwarding predicates", predicates that do nothing
except call the moved predicates in io.file.m, to provide backward
compatibility. But do mark the forwarding predicates as obsolete,
to tell people to update their (at their leisure, since the obsoleteness
warning can be turned off).
Also leave behind in io.m the definitions of the two types used
by some parameters of some of the moved predicates. Document the reason
why this is done.

Standardize messages about reading files.
compiler/read_modules.m:
When reading in Mercury source files, interface files or optimization
files, we optionally generate progress messages of the form
% Reading module xyz... done.
But the form of these messages has not been consistent, so that
when reading .opt files, we got messages of the form
% Reading xyz.opt...
% Done.
And we sometimes got messages such as
% Reading .int file for module xyz.int... done.
This is mostly because responsibility for constructing these messages
has been dispersed; different parts of it were generated in different
places, and sometimes when one place switches to a new scheme, not all
the corresponding places where updated accordingly.
This diff changes that by constructing these messages in two predicates
(output_read_msg and output_read_done_msg) in this module, leaving to
callers only a choice between a set of four message forms.
To make this possible, move the read_module_{plain,trans}_opt predicates
here from grab_modules.m. Their equivalents for reading Mercury source
files and interface files were here already, so here is where they belong.
Add several "XXX CLEANUP" markers for future changes.
compiler/parse_module.m:
Do not expect callers to compute the filenames containing .opt
and .trans_opt files, since the code here already does that.

Stop counting errors in module_infos.
Over time, we have almost completely switched over to using error_specs,
using their severity (if not yet printed out) and their effect on the
exit status (if already printed out) to represent the presence of errors,
leaving only a few places that either updated or paid attention to the
num_error field in the module_info. This diff completes that process.
compiler/hlds_module.m:
Delete the num_errors field in the module_info, and the predicates
that operate on it.
compiler/hlds_error_util.m:
Delete module_info arguments whose only purpose was to update the
now-delete field.

Delete the old write_error_spec predicates that updated a count of warnings
and a count of errors.

Separate always_treat_as_first from treat_as_first.
compiler/error_util.m:
The internal operation of formatting error messages requires knowing
whether an error_msg should be treated as the first message, or not.
(First messages get indented 1 space; other messages get indented by 3.)
We use the treat_at_first type for this.
In the past, we also used this type in error_msgs themselves, but there,
one of the alternatives of the type, do_not_treat_as_first, is misleading.
Such messages will in fact be treated as first if they are in fact
the first error_msg in an error_spec, which happens quite frequently,
since *most* error_specs contain only one error_msg.
This diff therefore defines a new type, always_treat_as_first,
whose two values have names that *accurately* reflect their meaning:
always_treat_as_first, and treat_based_on_posn. Make all code outside
error_util.m itself use this type; restrict the use of the treat_as_first
type to just the code that does error message formatting.

Fix a possible silent failure when making .int files.
When I split two files in a recent change, I ran into an annoying problem.
The problem was caused by unneeded imports in the interface of the new modules,
whose initial part I originally simply copied from the source module.
The problem was that when I attempted to compile new module A which imported
new module B, the compilation of module A would fail with a message about
not finding module B's .int file. It couldn't find B.int because the
compiler invocation that was supposed to create it failed, but it did not
print any error message about *why* it failed, and as a consequence,
it also did not set the exit status to nonzero to tell mmake that
the file was not actually built, so later build actions that need that file
should not be executed.
The cause of this problem was the following.
- The default value of the --warn-unused-imports is off, but COMP_FLAGS
turns it on for modules in the compiler directory. This enables warnings
generated by unused_imports.m.
- There is code that does a similar job in module_qual.qual_errors.m, but
that one is limited to imports in interface sections. Due to the overlap
between tasks, when this code finds an unused import_module declaration
in an interface, it generates an error message that was conditional
on --warn-unused-imports being off. When it was on, as it is with
COMP_FLAGS, it generates an error_spec that, when given to write_error_specs,
generates no output.
- Code in write_module_interface_files.m that decided whether the building
of the .int file has failed, tested only whether the process of generating
its contents has returned any error_specs, not whether it returned
any error_specs that would actually be printed, and, by being printed
with a sufficiently high severity, would set the exit status to signal
failure.
compiler/error_util.m:
The two changes to this file together fix the root cause of this problem.
First, a new predicate checks whether an error_spec has any part
whose printing is NOT disabled by being attached to an unmet condition.
Second, the predicate through which we pass all error_specs created
during the generation of the contents of the .int file filters out
any error_specs that yield no output.
The later changes are not strictly part of the bugfix, they are there
simply to make the code simpler to understand, in the hope that this fact
will reduce the probability of similar problems in the future.
compiler/module_qual.qual_errors.m:
Instead of generating error_specs that are conditional on
--warn-unused-imports being OFF, generate them conditional on
the new option --warn-unused-interface-imports being ON.
Using --warn-unused-imports here was strange because that option controls
whether the compiler invokes unused_imports.m. It was NOT specific
to this piece of code, while the new option is.
compiler/options.m:
doc/user_guide.texi:
Add the new option. Comment out its documentation, since I don't think
I can describe the reason for its existence simply enough for users
to understand.
compiler/handle_options.m:
Turn off the new option --warn-unused-interface-imports if
--warn-unused-imports is set. This duplicates the old behavior
of module_qual.qual_errors.m.
Turn off the new option --warn-unused-interface-imports if
we are generating interface files. This is because the presence
of unneeded imports in .m files does not prevent the creation
of valid .int files, so having to fix such warnings at .int file
creation time interferes with the programmer's ability to choose
the order in which he/she works on getting modules to a compilable shape.
compiler/write_module_interface_files.m:
Generate all output on error as part of an error_spec.
compiler/unused_imports.m:
Fix indentation.

Remove obsoleted interface files.
compiler/write_module_interface_files.m:
When we get errors that prevent us from constructing a new valid version
of an interface file, delete both
- any existing copy of that interface file to prevent its now-outdated info
from causing misleading error messages when compiling other modules, and

Make --halt-at-invalid-interface the default.
NEWS:
Mention this fact.
Group related changes together.
Fix some typos.
compiler/error_util.m:
Let the halt_at_invalid_interface option govern whether we print error
messages when we generate .int/.int2 files, rather than
the print_errors_warnings_when_generating_interface option.
This simplifies the use of that option.
compiler/options.m:
doc/user_guide.texi:
Document the halt_at_invalid_interface option.
Delete the print_errors_warnings_when_generating_interface option,
since its functionality has been subsumed into halt_at_invalid_interface.
compiler/grab_modules.m:
Check the accessibility of imported modules not just when generating target
language code, but also when generating .int/.int2 files. Without this,
the test_nested test case, which this diff moves from invalid to
invalid_make_int, would miss out on some errors being reported
in its new home.
To make the above possible, refactor the code that does the check
to let it work on aug_make_int_units as well as from aug_compilation_units.
Make the wording of any error message depend on where the info came from,
because unlike aug_comp_units, aug_make_int_units work with an
known-incomplete picture of the relevant info.
Update some obsolete comments.
compiler/write_module_interface_files.m:
Add a comment about a design decision that affects this diff.
tests/invalid_make_int/Mercury.options:
tests/invalid_make_int/Mmakefile:
Add to this directory's list the test cases that this diff moves
to this directory from other test directories, because the errors
that they test for are now reported at interface generation time.
Fix the rule handling multimodule tests, now that we have some :-(
Specify -j1 for this directory, since the two tests moved here
from invalid_submodules include nested submodules.
tests/invalid_make_int/bad_type_class_constraint_intermodule.{m,int_err_exp}:
Move this test case here from invalid, renaming files slightly,
and update the expected output.
tests/invalid_make_int/bug499.{m,int_err_exp}:
Move this test case here from invalid, and update the expected output.
tests/invalid_make_int/int_impl_imports.{m,int_err_exp}:

Move this test case here from invalid, and update the expected output.
tests/invalid_make_int/missing_interface_import2.{m,int_err_exp}:

Move this test case here from invalid, and update the expected output.
tests/invalid_make_int/missing_parent_import.{m,int_err_exp}:

Move this test case here from invalid_submodules,
and update the expected output.

Move this test case here from invalid_submodules,
and update the expected output.

tests/invalid_make_int/parent.undeclared_child.m:
tests/invalid_make_int/parent2.child.m:
tests/invalid_make_int/parent2.m:
Move this test case here from invalid, and update the expected output.
tests/invalid_make_int/transitive_import.{m,int_err_exp}:
Move this test case here from invalid, update it,
and update the expected output.
tests/invalid/Mmakefile:
Delete from the list of tests in this directory the tests
moved to invalid_make_int, and test bug521.
tests/invalid/bug521.{m,err_exp}:
tests/invalid/bug521_sub.m:
Delete this test. invalid_make_int already had a copy of the relevant
part of this test.
tests/invalid_submodules/Mmakefile:
Delete from the list of tests in this directory the two tests
moved to invalid_make_int.
Delete from the list of tests in this directory two other tests
for which we now detect some or all of the errors tested for
at interface generation time, but which are already covered
by other tests.
tests/valid_make_int/Mmakefile:
Delete from the list of tests in this directory the test
moved to invalid_make_int. (We could successfully generate
a .int file for that test case *only if* we did not check it
for errors :-)
tests/valid_seq/intermod_nested_module_bug2.m:
tests/valid_seq/intermod_nested_module_bug2.sub.m:
Move two module imports from the parent to the child module,
because only the child needs them, and any compiler with this diff
will now complain about them being unused in the parent
at interface generation time. Delete a third import, which was
not used anywhere.

Process parse_tree_int[012], not parse_tree_int.
compiler/recompilation.version.m:
Compute version numbers for parse_tree_int[012], not parse_tree_int.
Group gathered items and gathered instances into a single type.
Change argument lists to consistently put old things (gathered items,
gathered instances, version numbers) before new.
compiler/write_module_interface_files.m:
Compare new version numbers vs old for parse_tree_int[012],
not parse_tree_int.
compiler/prog_item.m:
Move the parse_tree_int type to convert_parse_tree.m, since now
it is used only by the parser, which them immediately converts
the generic parse_tree_int to parse_tree_intN for the required N.
compiler/convert_parse_tree.m:
Move the parse_tree_int type here.
Delete the predicates that convert parse_tree_int[0123] to parse_tree_int,
since they are not needed anymore.
compiler/parse_module.m:
compiler/read_modules.m:
Delete the predicates that read in parse_tree_int,
since they are not needed anymore.

Stop using exit status to report success/failure.
compiler/make.module_dep_file.m:

checking the exit status in the I/O state.
compiler/module_cmds.m:

Introduce aug_make_int_unit.
compiler/prog_item.m:
Split aug_compilation_unit into two types. One, aug_make_int_unit,
is a new type, and it is a version of the old aug_compilation_unit
that contains only what is needed when making .int{,0,2} files.
The other, the new aug_compilation_unit, contains what is needed
when generating target language code. Both encode in their argument types
stronger invariants that the old aug_compilation_unit type did.

compiler/write_module_interface_files.m:
Conform to the change above.
In some cases, this means passing around aug_make_int_units instead of
aug_compilation_units.
In a few cases, it means creating two copies of a predicate,
one for aug_compilation_units and one for aug_make_int_units.
In such cases, factor out any commonalities between the copies.
In many cases, it means updates to account for the specialized types
of the fields of aug_compilation_unit or aug_make_int_unit.
In some cases, it means deleting code that was always unreachable,
but the not-tight-enough types did not make this fact visible.
(Due to this effect, this diff removes more lines than it adds.)

Replace module_and_imports with aug_compilation_unit.
compiler/module_imports.m:
Delete the module_and_imports type, and replace its uses with
aug_compilation_units.
The structure of module_and_imports used to be private, but the
structure of aug_compilation_units is public. Delete the getter/setter
predicates on module_and_imports structures that can now be done
using field names on aug_compilation_units. Delete, along with this,
the infrastructure for keeping track of which module_and_imports fields
are ever accessed. It has served its purpose, but it won't be needed
anymore.
Change types that used to include module_and_imports to include
aug_compilation_units instead.
Rename any types, predicates and functions that used to contain
the "module_and_imports" string in their name.
compiler/prog_item.m:
Move the version number map to be the last field of aug_compilation_units,
as it used to be in module_and_imports structures, since this fits better.
compiler/get_dependencies.m:
Make the name of a predicate more reflective of the type it returns.

Introduce and use module_baggage.
compiler/module_imports.m:
Keep in the module_and_imports structure only the fields that used to
construct aug_compilation_units, to prepare for the replacement
of module_and_imports by aug_compilation_unit. Move the remaining fields
into a new structure, the module_baggage, and introduce a new type,
module_imports_and_baggage, that contains module_and_imports (for now)
and module_baggage.
The point of this is to allow the splitting of aug_compilation_unit
into types:
- one (aug_compilation_unit itself) for use when generating
target language code, and
- one (maybe named aug_make_int_unit) for use when generating
.int/.int2 files.
These two use cases fill some of the fields, such as direct and indirect
imports, with different kinds of parse trees. Until now, we handled this
using types such as direct_int_spec, which could contain either kind
of parse tree, but having separate aug_compilation_unit/aug_make_int_unit
types would allow the compiler to enforce the different invariants
of the two use cases.
This split requires factoring out the common parts of module_and_imports
structure. The module_baggage type contains these common parts.
Simplify some operations as permitted by the above change.
Rename others to reflect the new names of the types they operate on.
Don't return an output argument that is contained in another output
argument.
Delete operations on deleted fields.
Delete a predicate that has become identical to another.
compiler/grab_modules.m:
Add operations on module_baggage (that previously were operations on
module_and_imports) that are needed only in this module.
Conform to the changes above.

Break a source file info parse_tree_module_srcs ...
... instead of into raw_compilation_units. Besides being more convenient to
work on, a parse_tree_module_src encodes in its type a significant number
of invariants that a raw_compilation unit does not.
compiler/split_parse_tree_src.m:
Immediately after creating a raw_compilation_unit for one of the modules
in a potentially multi-module source file, convert it to a
parse_tree_module_src.
Fix an old problem that can come up in contrived erroneous code.
Specifically, when a submodule is both nested inside its parent module,
*and* it also has an explicit include_module declaration, we used to
record the contexts of both "inclusions", after generating an error
message. The more rigorous checking that later code now does on the
resulting inclusion map would look at this "duplicate inclusion"
and generate *another* error message. To avoid this redundant message,
do not record the contexts of erroneous inclusions for which a message
has already been generated.
compiler/grab_modules.m:
Operate on parse_tree_module_srcs instead of raw_compilation_units.
This allows us to avoid having code for doing what converting the
raw_compilation_unit to a parse_tree_module_src has already done.
In fact, that conversion code does a better job. The old code assumed
that all implicitly available modules are used in the interface,
whereas in fact only some should be used in the interface, with
the rest being used in the implementation section.
compiler/module_imports.m:
Make the predicates that create module_and_imports structures
take a parse_tree_module_src instead of a raw_compilation_unit
as input. For now, we convert the parse_tree_module_src back to
a raw_compilation_unit for further processing, but I intend
a later diff to change this. Nevertheless, one immediate change
is that init_module_and_imports now stores the *actual*
parse_tree_module_src in the module_and_imports structure,
not a dummy.
compiler/prog_item.m:
Do not include a list of foreign_enum items in the interface section
of a parse_tree_module_src, since such items are not allowed to occur
in interface sections.
For the same reason, delete the field for foreign_enums in the interface
sections of .int0 and .int files.
compiler/check_raw_comp_unit.m:
Operate on parse_tree_module_srcs instead of raw_compilation_units.
compiler/comp_unit_interface.m:
Operate on parse_tree_module_srcs instead of raw_compilation_units.
Do not expect any foreign_enum items in interface sections, since
they are not allowed there.
compiler/read_modules.m:
Provide a mechanism to remember having read a parse_tree_module_src.
compiler/write_module_interface_files.m:
Operate on parse_tree_module_srcs instead of raw_compilation_units.
compiler/get_dependencies.m:
Add a new version of an existing utility predicate. The old one operated
on raw item lists, the new one operates on parse_tree_module_srcs.
To make this possible, factor out the code pieces that operate on
each non-ignored kind of item.
compiler/item_util.m:
Add some new utility predicates/functions.
compiler/convert_parse_tree.m:
Conform to the change in prog_item.m. (We already generated an error
message for a foreign_enum item in the interface, but still passed around
a list of foreign_enum items that was guaranteed to be stay empty.)
compiler/make.module_dep_file.m:
Conform to the changes above.
Use explicit streams in one place.
Do not pass an unneeded argument.
compiler/check_parse_tree_type_defns.m:
compiler/equiv_type.m:
compiler/make_hlds_separate_items.m:

compiler/mercury_compile_main.m:

compiler/parse_tree_out.m:

library/map.m:
library/tree234.m:
Add foldl6, foldl6_values and foldr6 predicates. An earlier version
of this diff needed foldl6, and I added the others for symmetry.
NEWS:
Announce the new library predicates.

Specify streams explicitly in more modules.
compiler/module_cmds.m:
Require all callers to specify output streams explicitly.
compiler/compile_target_code.m:
Require callers to specify output streams explicitly in most cases.
In the remaining cases, add "XXX STREAM" comments to request that
the explicit streams be passed later.
Add XXXs where preserving old behavior results in wrong-looking code.
Modify the signature of compile_java_files to encode the invariant that
the list of Java files given to it may not be empty.

compiler/make.build.m:
Mark predicates that help redirect implicit streams as predicates
that should not be used.
compiler/make.module_target.m:
compiler/make.program_target.m:

Specify output streams in some places.
Besides this main purpose, this diff also replaces code that calls
io.write_string several times in a row with code that prints the
thing to be printed in one go with io.format. In a couple of places,
this has caught (and fixed) bugs where we wanted to put `' quotes
around a filename, but printed only one of the two quotes.
compiler/file_util.m:
Provide alternatives to the existing maybe_report_stats,
maybe_write_string and maybe_flush_output predicates that explicitly
specify the output stream.
Rename report_error_to_stream as report_error, to allow
--warn-implicit-stream-calls to report calls to the existing report_error
predicate, which does not take an explicit output stream.
Add a module_name argument to the output_to_file_stream predicate,
to allow its code to figure out where to print both progress and
error messages.
compiler/module_cmds.m:
Add a module_name argument to the predicates that update interface,
to allow their code to figure out where to print both progress and
error messages.
For now, leave the predicates that issue commands that are not
clearly linked to a single module using implicit streams.
compiler/pd_debug.m:
compiler/analysis.file.m:
Specify output streams in some places.
In other places, doing so would require redoing the whole debug
infrastructure, since the current one is based on higher order predicates
that always write to the non-explicitly-specified *current* output stream.
compiler/passes_aux.m:
Provide predicates that get progress, debug and error streams
given a module_info, by extracting the globals and the module name
from the module_info, and then calling the predicates in globals.m
to get those streams. Doing this sequence of actions here factors out
what would otherwise be repeated code in many other parts of the compiler.
