compiler/file_util.m:
Define standard routines for reporting that we couldn't open a file
for either input or output. Rename the one other predicate in this file
that the compiler used for that purpose, so that its call sites
can be redirected to use one of the routines intended for this purpose.
Give these routines the ability to standardize path names (by removing
"./" prefixes from relative path names, and removing all directory names
from adsolute path names) if a new option is given.

Add that (developer-only) option.

compiler/module_cmds.m:
Change the predicates that write out launcher script files to take
as input not a higher-order predicate that does the writing, but
simply the string to be written.
compiler/compile_target_code.m:
Conform to the change above.
compiler/globals.m:
Add to the globals structure a field that holds the pathname component
identifying the grade (in the names of grade-specific files).
We used to compute it every time we needed it, using a relatively slow
algorithm; we now compute it just once, when the globals structure
is created by the globals_init predicate.
Put the main read-only fields of the globals into a substructure,
to make any updates of the writeable fields faster by reducing the size
of the globals structure itself,
Change the order of the arguments of globals_init, and the order of the
getter and setter predicates of the globals structure, to match the
new order of the fields in the globals structure.
Don't mix other predicates in with the getter and setter predicates.
compiler/compute_grade.m:

just this one filename.

to make them easier to find when we *do* start to make use of the proposed
file names (first alongside the legacy names, and then without them).
In some places, make variable names more descriptive.
library/set.m:
Add utility predicate for use by a diff to one of the modules above.
NEWS.md:
Announce the new library predicate.
compiler/generate_mmakefile_fragments.m:
Replace an (indirect) call to module_name_to_file_name
with the extension ext_cur_gas_exec_noext. The call's result
was used as part of the name of a make variable, which meant
that the presence of a directory name component in the result
(which could happen with --use-grade-subdirs, if that were ever
supported by mmake) would be a bug.
compiler/module_cmds.m:
Make a variable name descriptive enough to make clear
that there is no such abuse here.
compiler/file_names.m
Separate "gs" (grade-specific but not architecture-specific) extensions
from "gas" (both grade- and architecture-specific) extensions.
The intent is to eventually install them into different directories,
but that is for future diffs.
Change the functions that return directory paths into predicates.
A future change will update them to return *two* directory paths:
one for the LEGACY directory structure, and one for the PROPOSED
structure.

Pass the full names of extension-specific directories, instead of
letting callees construct it by adding a "s" suffix to the
extension string. This fixes the above inconsistency.
Test whether use_symlinks is set just once.
compiler/module_cmds.m:
Provide a version of maybe_make_symlink that assumes that the caller
has already tested use_symlinks.
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.
The compiler has long had code for recursively copying directories (via
"cp -R"), but it does not, in fact, use it anywhere.
compiler/make.program_target.m:

compiler/copy_util.m:
Delete the comment about moving directory copying to this module.
Delete the XXX about the Mercury copying code not preserving
permissions; it now attempts to do so.
NEWS.md:
Announce the deprecation of --install-command-dir-option.
Document why the compiler copies files and what mechanisms are available for
doing so.
When copying temporary interface files, do not use the Mercury copy_file
procedure as a fall back when invoking an external file copy command fails.
Use the value of the --install-method option to select whether we use an
external command to copy a file, or instead use a library procedure.
compiler/copy_util.m:
Document why the compiler (as opposed to mmake) copies files.
Document the mechanisms available to it for doing so.
Split copy_file/7 into two predicates: copy_file_to_file_name/7 and
copy_file_to_directory/7. These two predicate correspond to the
actual file copy use cases in the rest of the compiler.
Document some assumptions made by the rest of the compiler about
how file copying behaves.
Do not fallback to using the file copy procedure written in Mercury if
invoking an external command fails when copying a file to a file.
(When copying a file to a directory, we only ever used an external
command.)
Make the choice of file copy mechanism depend on the value of
the --install-method option.
compiler/make.program_target.m:
Use copy_file_to_directory/7 rather than invoking an external command
here directly.
compiler/module_cmds.m:
Use copy_file_to_file_name/7 here. Conform to changes in the way errors
are reported during file copying. There are couple of spots marked
XXX FILE COPY, where the caller previously assumed an io.error would
be returned to it -- this probably never happened in practice since
when using an external command invoke_system_command does the error
reporting. I'll tidy this up in a later change.
compiler/module_cmds.m:
Move the predicate copy_file/6 from here ...
compiler/copy_util.m:
... to here. The code is otherwise unchanged.
compiler/libs.m
Include the new module.
compiler/notes/compiler_design.html:
Document the new module.
Move the code used for invoking commands via the shell out of the module_cmds
module and into its own module. In doing so, this moves it from the parse_tree
package into the libs package.
compiler/module_cmds.m:

... and almost all calls to get_error_output_stream. Replace them
with ProgressStreams and ErrorStreams passed down from higher in the
call tree.
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:
Delete the predicates that return progress streams, and the mutable
behind them.
compiler/passes_aux.m:
Delete the predicates that return progress streams. Delete the
versions of the progress-message-writing predicates that didn't get
the progress stream from their caller.
compiler/*.m:
Pass around ProgressStreams and/or ErrorStreams explicitly,
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.
Delete such unused ModuleNames.
In a few places, change argument orders to conform to our usual
programming style.
Fix too-long lines.
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.

Conform to the changes above, mostly by passing along
an explicit progress stream.
Previosly, there were three places in the compiler that had code to compute
the name of the directory where .class files are stored. Replace two of
these with calls to the third.
compiler/file_names.m:
Compute the three components of files, that is
- the dir names list that together specify a relative path,
- the file's base name and
- the file's extension string
in three separate predicates. Export the new predicate doing just
the first job; the functions doing the second and third jobs were
already exported.
Make the code computing the dir names list for .java and .class files
call get_java_dir_path. This replacement of the old get_class_dir_name
predicate is now the place that every part of the compiler calls
for this info.
As part of this last change, add the "jmercury" component to the path
for .java and .class files separately, since we need the path both
with and without this extension. This change allows a simplification
of the make_grade_subdir_name function.
compiler/compile_target_code.m:
Call the new get_java_dir_path predicate in file_names.m instead of
including a duplicate copy of its logic.
compiler/make.program_target.m:
Add an XXX on code that *looks like* it should either be in
file_names.m or use code in file_names.m, but which cannot be easily
updated using either approach, because its purpose is undocumented.
compiler/mercury_compile_main.m:
compiler/module_cmds.m:
Conform to the changes in file_names.m.
compiler/file_names.m:
Replace the current groups of extensions, which are based on the
shared purpose of the files with those extensions, with a smaller
number of groups, which are based on the algorithm we use to decide
in what (sub)directories we want to place files with those extensions.
The old distinctions based on purpose still remain in the naming
convention for the enum values within each of the new groups.

Define a new enum type with three values, which represents the three
legal combination of the values of the use_subdir and use_grade_subdir
options.
Add a field of this type to the globals.
compiler/handle_options.m:
Set up the value of this field in the globals. This means initializing
it to a non-meaningful value when the globals is first created, and
filling it in with the final meaningful value when we finish the setup
of the global structure.
compiler/options.m:
Add a "setting_only_" to the internal names of the use_subdir and
use_grade_subdir options, to signal that their only valid use
from now on is in deciding the value of the new globals field.
(Their user-facing names remain unchanged.)
compiler/compile_target_code.m:
compiler/file_names.m:
compiler/make.program_target.m:
compiler/module_cmds.m:
compiler/write_deps_file.m:
Rewrite code that used to make decisions based on the values of
the use_subdir and use_grade_subdir options with code that makes
decisions based on the value of the new field. A field retrieval
followed by a three-way switch is simpler (and faster) than
two option lookups and one two-way switch inside another.
Consistently reorder the code so that the code of the simpler cases
come first.
Note a situation where we should be using an even simpler basis
for the decision.
compiler/module_cmds.m:
Rename the update_interface_X predicates to copy_dot_tmp_to_base_file_X,
because
- this better describes what they do, and
- some of the files they are invoked on are *not* interface files.
Add an extra parameter to copy_dot_tmp_to_base_file_report_any_error
that specifies what kind of file is being copied, and print *that*
as part of any error message.
Do a similar rename of update_interface_result type, and of its
function symbols.
Give more meaningful names to touch_interface_datestamp and
touch_datestamp as well.

other than module_name_to_source_file_name and the ones that create
directories.
compiler/file_kind.m:
Delete the ext output argument of file_kind_to_extension, because
we can't return ext_src for fk_src anymore.
compiler/write_deps_file.m:
Delete a test for ext_src which could never succeed, because the
predicate in question is never called with ext_src.

- 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
out of the ext type.

Delete the newext_other extension category, since it was also needed
only for that purpose. Delete all the code that supported it.
Switch the infrastructure for recording the demand for translations
to work with the new code.
compiler/analysis.file.m:
Delete functions that returned old-style extensions, which are
not useful anymore. The new-style extensions, by identifying
extensions via enums rather than strings, serve the purpose
for which these functions were created.
compiler/mercury_compile_main.m:
Move the code to call to write out the translation record
from just after a call to real_main_after_expansion to the

real_main_after_expansion has access to a globals structure,

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.

NEWS:
Announce the above changes.
Specialise the Mercury implementation of file copying in the compiler by
avoiding the use of io.binary_input_stream_foldl_io/5. This allows us to avoid
a higher-order call each time a byte is written and it allows us to use the
unboxed version of the predicate that reads bytes. The other reason for this
change is that we are planning to deprecate (and eventually remove)
io.binary_input_stream_foldl_io/5.
compiler/module_cmds.m:
As above.
Add a comment about improving the Mercury implementation of file copying.
Fix spelling in a spot.
library/io.m:
Refer to the Boolean constant yes/0 and no/0 in C code as MR_YES
and MR_NO respectively, rather than MR_TRUE and MR_FALSE.
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.

compiler/module_cmds.m:
Read in both files as a single string each and compare the strings,
instead of comparing the files' bytes one-by-one using higher order code.
The new code is much, much simpler. It does always read in all of
both files while the old code would stop at the first difference, but
- the usual case is that the interface of a file does not change
after the source file itself changes, and
- the new code should have significantly lower constant factors,
so the speedup on "no difference" cases should balance any slowdown
on "there is a difference" cases.
The old code could also handle non-text files, but if the compiler
ever puts non-text bytes into interface files, we have bigger problems
than possibly invalid comparison results.

Use the new types instead of bools where applicable.
Do not look up the value of the keep_going option in the globals
when its value (converted to the maybe_keep_going type) is available
in the make_info.
Use standard terminology in variable names.
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/error_util.m:
Provide a version of an error predicate that takes explicit streams.
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:
Add "XXX STREAM" comments to request that the explicit streams
be passed later.
compiler/module_qual.m:
Provide a means to construct the debug output stream.

Use the debug output stream where relevant.

Stop specifying --no-warn-implicit-stream-calls for the above modules
(those that had it specified in the first place).
Delete a long-unneeded workaround.
compiler/mercury_compile_front_end.m:
compiler/mercury_compile_llds_back_end.m:
compiler/mercury_compile_main.m:
compiler/mercury_compile_middle_passes.m:
Specify progress and output streams explicitly when calling the modules
above (not in other places, just yet).
library/dir.m:
Add a new predicate general_foldl2. Unlike foldl2 and recursive_foldl2,
this predicate can be asked to keep going after finding errors,
in which case it will return a structured description of those errors.
To make this possible, generalize the infrastructure shared by foldl2,
recursive_foldl2 and now general_foldl2.
NEWS:
Announce the new predicate.
compiler/module_cmds.m:
Use the new predicate instead of recursive_foldl2 when looking for
.class files to build Java archives from. Doing so means that when
e.g. bootcheck runs several test cases at the same time in the same
directory, the traversal in one test case will NOT stop when a different
test case deletes one of its .class files between the time the first test
case has read a directory, and the time it gets around to processing those
entries. Instead, general_foldl2 will simply return an error description
in each such case. If an error description is for a file that is not
relevant to the current test case, we will now ignore it.
This should eliminate many spurious test case failures in Java grades
that were caused by such interference between test cases. Unfortunately,
spurious test failures still happen for other reasons :-(
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.
Delete two predicates that were not used anywhere in the compiler.

Add an XXX about another option intended for Erlang being unused.
Leave the other erlang-related options alive for now, to avoid breaking
Mmakefiles, Mercury.options files etc that may still refer to them.
Delete references to Erlang in help and/or error messages.

Don't both updating options that were used only by the Erlang backend,

Delete a reference to a recently deleted .hrl file.
... using an approach proposed by Peter, with an extra twist from Julien.
Instead of having two modules, getopt.m and getopt_io.m, with the former
defining predicates that do not take an I/O state pair, and the latter
defining predicates that do take an I/O state pair, put both kinds of
predicates into a single module. The versions with an I/O state pair
have an "_io" suffix added to their names for disambiguation.
Both versions are a veneer on top of a common infrastructure,
which relies on a simple type class to implement the operation
"give the contents of the file with this name". The predicate versions
with I/O state pairs have a normal implementation of this typeclass,
while the predicate versions that do not have I/O state pairs
have an implementation that always returns an error indication.
The above change just about doubles the number of exported predicates.
We already had two versions of most exported predicates that differed
in whether we returned errors in the form of a string, or in the form
of a structured representation, with names of the latter having
an "_se" suffix. Since we agreed that the structured representation
is the form we want to encourage, this diff deletes the string versions,
and deletes the "_se" suffix from the predicate names that used to have them.
(It still remains at the end of the name of a type.) This "undoubling"
should offset the effect of the doubling in the previous paragraph.
Eventually, we want to have just one module, getopt.m, containing
the updated code described above, but for now, we put the same code
into both getopt_io.m and getopt.m to prevent too big a shock to
people with existing code that uses getopt_io.m.
library/getopt.m:
library/getopt_io.m:
Make the changes described above.

Instead of building both getopt_io.m and getopt.m from getopt_template,
build getopt.m from getopt_io.m.

Delete references to getopt_template.

When a type error involves one of the getopt/getopt_io predicates
whose interfaces are changed by this diff, tell the user about
how these changes could have caused the error, and thus what the
probable fix is.

compiler/file_names.m:
Split the ext type into ext_src and ext_other, as mentioned above.
Add the first predicate for checking whether a string falls into
a given category of extensions.
Add an XXX proposing a better solution for an old problem that does not
actually arise in practice.
compiler/compile_target_code.m:
Split the two-moded predicate maybe_pic_object_file_extension into
two separate one-mode predicates, one for each old mode. The
implementations of the two modes were already separate, because
the two modes already did different jobs: while one went from PIC
to an "extension", the other went from an "extension string" to PIC.
Until now, "extension" and "extension string" were equivalent;
after this diff, they aren't anymore.
Delete an unused argument.
compiler/make.util.m:
Split the two-moded predicate target_extension into
two separate one-mode predicates, one for each old mode,
for the same reason as maybe_pic_object_file_extension above:
the fact that "extension" and "extension string" are now distinct.
compiler/options_file.m:
Move debug infrastructure here from mercury_compile_main.m, to help
debug possible problems with options files. (I had such a problem
while writing this diff.)

... to allow later changes to its definition.
compiler/file_names.m:
We used to represent filename extensions simply as strings. This meant
all calls to the predicates in file_names.m that convert module names
to file names with various suffixes had to go through a complicated
sequence of tests that effectively partition the extensions into
several classes, with all extensions in a class being treated the same
but different classes being treated differently. And since this general
translation process is quite convoluted (which is not helped by it
being spread across several predicates), it is very hard to construct
a correctness argument for it.
It would be better to represent the different classes of extensions
explicitly, in a du type, with each function symbol of that type
representing all the extensions in the corresponding class (in the sense
of the paragraph above). However, getting there in one diff would make
that diff far too hard to test and to review. So this first diff
starts by simply making extension a notag type.
The above is the first step in implementing one old XXX. This diff
fully implements another old XXX, which is to make the argument order
of several predicates friendly to higher order code.
Add infrastructure for profiling how often this code makes directories.
Delete an unused type.
Add comments outlining proposed future improvements.

Consistently use "Ext" for the abstract representation of extensions

of extensions into classes.
