Makefile (%.expected): New implicit rule. Whenever a test requires a
.expected file, if it is missing, we create an empty one.
This file will be treated as an intermediate by GNU Make, which means
that it will be deleted when make terminates.
* tests/012/compile.tl: Some of the .tl files no longer have
an .expected file, so we have to test for that in the
catenating logic.

* Makefile (%.tab.c %.tab.h): Remove the trick of keeping the
old y.tab.h file if it has not changed. This was once a good
idea, but now that we have a proper grouped targets pattern
rule which knows that y.tab.h depends on and is produced from
parser.y, the trick causes y.tab.h to be perpetually out of
date due to its old time stamp, and so yacc is run on every
build.

The MacOS sed doesn't accept semicolon termination for
commands involving defining labels or branching to labels.
This is not a new issue, but it is revealed on newer MacOS
because the sed now complains about unused labels.
In the sed command ':x; /whatever/ { ...; tx }', everything
after the initial : is interpreted as a label.
* Makefile (DEPGEN): Split the sed command's syntax up into
logical lines using multiple -e commands, applying some
formatting with indentation to try to keep it readable.
It looks like multiple -e options just glue together to
make a program, as if they were lines of code; one -e
can define a label referenced by another, and even the
closing brace can be treated as a separate command.

Thanks to a recent discussion in the GNU Make mailing list
about some issue related to grouped patterns, I hit upon the
realization that the rule y.tab.h y.tab.c: parser.y has
a common stem, y, which can be exploited to write a pattern
rule. This is only active in maintainer mode; in user mode,
the y.tab.h and y.tab.c are separately produced from .shipped
files.
* Makefile (y.tab.h): Eliminate rule which detects a removed
y.tab.h.
(y.tab.c): Delete rule, replacing with new rule.
(%.tab.c %.tab.h): New pattern rule, which groups the targets
together.

I'm giving up and just using a recursive make invocation
for the "retest" target.
* Makefile (retest): Depend on nothing. Remove the tst
directory and invoke make tests recursively.

Over two years ago, I disabled parallel building with a
.NOTPARALLEL: directive in the Makefile, due to some rules
that depended on order of updates of their prerequisites.
Today the situation is better. It looks like there are just a
few rules that have to be fixed, all in the area of executing
tests.
Let us not enable that by default, though, to protect
downstream users from themselves. Some operating system
distribution builds optimistically run make -j N on all the
packages, and then have to deal with sporadic breakages when
some of those packages have parallel build bugs. We can
prevent TXR from ever being implicated in such a breakage by
turning off parallel building even if make -j requests it.
There will now be a ./configure --parallelmake option
to allow parallel builds, off by default. The --maintainer
configuration mode will flip that default; configuring in
maintainer mode will enable parallel builds, unless explicitly
disabled with --no-parallelmake.
* Makefile (.NOTPARALLEL): Conditionally assert, if
parallelmake is false.
(tst/tests/014/dgram-stream.ok,
tst/tests/014/socket-basic.ok): Enforce order between these
two tests. They clash in their use of network ports so cannot
run at the same time.
(test.clean): test.clean must finish executing before tests;
enforce order.
* configure (parallelmake, parallelmake_given): New variables.
(help text): Add parallelmake option to help.
(gen_config_make): Generate the parallelmake make variable
into config.make.
New script section, defaulting parallelmake to y in maintainer
mode.

This patch causes TXR to treat calls to verticatl functions,
as well as the @(call) directive to be considered non-matching
directives, so that opening the data source is deferred.
This allows included .txr files to call the funtions that they
define, without the side effect of standard input being read.
* match.c (open_data_source): Function refactored to reduce
duplication. c->data is checked first, and if it is not t,
nothing is done, making the function cheaper in the frequent
case. The non_matching_dir condition changes. We now check
that the first element of the first spec is a non-nil symbol.
If it has a function binding as a vertical function, then
that is considered non_matching.
(dir_tables_init): Treat @(call) as a non-matching directive.
* Makefile (tst/tests/008/no-stdin-hang.ok): Add -n argument
for non-interactive, which will cause stdin to be read in
that test case if there is a regression in this change. If
make tests is run in a terminal, this will hang make tests.
* tests/no-stdin-hang.txr: New file.
* tests/no-stdin-hang.expected: New file.

* Makefile (tst/tests/000/binding.ok): Pass -B to txr for this
new test.
* match.c (v_rebind): Fix gaping copy-and-paste bug here,
which causes rebind to take on the behavior of local/forget;
it takes all symbols that appear as its arguments from the
environment and produces an environment in which they
don't exist. What we want is to remove the left
variables from the environment, and since that is a nested
pattern, the right way to do that is to flatten it.
Bug reported by Frank Schwidom.
* tests/000/binding.txr: New file.
* tests/000/binding.expected: New file.
* txr.1: Improve documentation of @(rebind), also making
improvements in @(set) documentation.

Our build system lumps all linker options together. The
correct way is that linker flags are separated info flags and
libs. Also, we respond to the LDFLAGS variable but ignore
LDLIBS which is incorrect. Other issues are fixed.
All that is fixed here.
* Makefile (TXR_CFLAGS): Interpolate $(CFLAGS) last, so that
options coming from CFLAGS can override previous options.
(TXR_LDFLAGS): Interpolate $(LDFLAGS) last; same reason.
(TXR_LDLIBS): New variable.
(LINK_PROG): Put $(TXR_LDFLAGS) with the options, before
the -o, and put $(TXR_LDLIBS) at the end.
* configure (conf_ldlibs, platform_ldlibs): New variables.
(usage text): Document platform-ldlibs and adjust
documentation of platform-ldflags.
(gen_config_make): Generate PLATFORM_LDLIBS and CONF_LDLIBS
now needed by Makefile.
(mainline): Adjusts various recipes to use conf_ldlibs
instead of conf_ldflags, or in some cases both.
In the case of libffi where we use pkg-config, we use the
special pgk-config options to separately extract the
flags and libs. We use EXTRA_LDLIBS instead of EXTRA_LDFLAGS
in some conftest invocations, as necessary.

* Makefile (conftest.android): New helper target for testing
for Android toolchain, via presence of __ANDROID__
preprocessor symbol, similarly to how we detect Darwin.
* configure: New test for Android. This is mutually exclusive
agains Darwin. On Android, we add some necessary feature
selection macros to the compiler command line.

The trick of declaring static arrays whose size is the value
of an integer is not working with newer gcc 10 on Cygwin,
because that compiler is rearranging the order of the arrays
and adding padding. Basically, the writing on the wall is that
this is not a good approach.
I'm switching to a different approach. By initializing a
suitable C structure (which contains character arrays) in a
particular way, we can create a .o file in which a shell
script is embedded. We can pull out the shell script and
evaluate it to get the sizes of types.
* Makefile (conftest.syms): Rule removed.
(conftest.clean): Don't remove conftest.syms.
* configure (conftest_syms, read_syms): Functions removed.
(LANG, LC_ALL): New environment variables. This is needed
because we are using tr to process a binary file;
we can't have it trying to decode multi-byte characters.
(mainline): Use new trick for obtaining variables like
SIZEOF_INT.

* Makefile (YACC_FLAGS): Removed. We don't need these because we
won't be trying to get newer Bison to behave like older Bison.
(y.tab.c): Drop reference to $(YACC_FLAGS).
* configure: Entire yacc-detecting section is conditional on
the maintainer Boolean variable. If the yacc program is
detected as Bison, check for version 2.5 and fail if not
found.

license from y.tab.c. Don't remove yyparse declaration from
y.tab.h. Provide a pattern rule for producing any missing
file X from X.shipped. That's how y.tab.c and y.tab.h
get produced from y.tab.c.shipped and y.tab.h.shipped,
respectively, in user mode.

There is now a ./configure --maintainer mode which establishes
a variable called maintainer in config.make, with a y value.
The initial use for maintainer mode will be that the Yacc
parser (the y.tab.c and y.tab.h) files will no longer be
regenerated whenever the parser.y file is newer.
In the following commit, I will add a generated parser.
* Makefile (y.tab.h, y.tab.c): These rules are now only
enabled in maintainer mode via an ifeq.
* configure (maintainer): New variable.
(gen_config_make): Generate maintainer make variable
definition in config.make.

The chmod fixes in the previous several commits were
caught by this.
* Makefile (tst/tests/018/chmod.ok): Set up TXR_ARGS for this
test to give it the location of the temporary file to use
as the object for testing permissions.
(tst/tests/018): Disable TXR_DBG_OPTS for new directory.
* tests/018/chmod.tl: New file.

The configure command line is now turned into an
executable script called reconfigure which can be invoked to
repeat the config.
* Makefile (distclean): Whether in a configured or state or
not, try to remove reconfigure. In the configured state, don't
remove config.log. (If distclean is invoked when not
configured, the config.* pattern will remove config.log).
* configure: rewrite the logic which turns the command line
into text. It is now robust against spaces, quotes and
meta-charaters. Moreover, the printed representation is chosen
according to good heuristics to minimize unnecessary quoting
and escaping. The config line is written into an executable
script called reconfigure. This is now done twice; it is done
immediately, so that we save the command line even if the
configure subsequently fails. A comment is added to
reconfigure indicating that configure didn't succeed. Then
after a successful run through the tests, we save it again,
without the cautionary comment. Help texts updated.

Newer versions of Bison produce spurious warnings in Yacc mode
about %pure-parser being not POSIX conforming and also
deprecated. Plus some strange fluff about "fix-its" that can
be applied if option --update is specified.
Let's detect at configure time whether the Yacc program
being used is actually Bison 3.0 or greater, and if so, give
it some flags to shut up these warnings.
* Makefile (YACC_FLAGS): New variable, conditionally set
based on yacc_is_newer_bison, also new variable, that being
generated into config.make.
(y.tab.c): Invoke $(TXR_YACC) with $(YACC_FLAGS).
(conftest.yacc-version): New phony target for running Yacc
with --version, out of the configure script.
* configure (yacc_is_newer_bison): New variable.
(gen_config_make): Generate yacc_is_newer_bison
make variable. New test for whether Yacc is Bison.
If so, and the version is >= 3.0, sets the
yacc_is_newer_bison variable to y.

Binary search tree nodes are being added as a basic heap data
type. The C type tag is TNOD, and the Lisp type is tnode.
Binary search tree nodes have three elements: a key, a left
child and a right child.
The printed notation is #N(key left right). Quasiquoting
is supported: ^#N(,foo ,bar) but not splicing.
Because tnodes have three elements, they they fit into TXR's
four-word heap cell, not requiring any additional memory
allocation.
These nodes are going to be the basis for a binary search tree
container, which will use the scapegoat tree algorithm for
maintaining balance.
* tree.c, tree.h: New files.
* Makefile (OBJS): Adding tree.o.
* eval.c (expand_qquote_rec): Recurse through tnode cells,
so unquotes work inside #N syntax.
* gc.c (finalize): Add TNOD to no-op case in switch; tnodes
don't require finalization.
(mark_obj): Traverse tnode cell.
* hash.c (equal_hash): Add TNOD case.
* lib.c (tnode_s): New symbol variable.
(seq_kind_tab): New entry for TNOD, mapping to SEQ_NOTSEQ.
(code2type, equal): Handle TNOD.
(obj_init): Initialize tnode_s variable.
(obj_print_impl, populate_obj_hash): Handle TNOD.
(init): Call tree_init function in tree.c.
* lib.h (enum type, type_t): New enumeration TNOD.
(struct tnod): New struct type.
(union obj, obj_t): New union member tn of type struct tnod.
(tnode_s): Declard.
* parserc.c (circ_backpatch): Handle TNOD, so circular
notation works through tnode cells.
* parser.l (grammar): Recognize #N prefix, mapping to
HASH_N token.
* parser.y (HASH_N): New grammar terminal symbol.
(tnode): New nonterminal symbol.
(i_expr, n_expr): Add tnode cases to productions.
(yybadtoken): Map HASH_N to "#N" string.

* Makefile (clean): If it exists, remove the temporary run.sh
that is generated by the install-tests target.
|
|
|
|

* Makefile (TXR_CFLAGS): Use := operator rather than += when
filtering out REMOVE_FLAGS, or else REMOVE_FLAGS are not
really removed, and we duplicate all the flags.

* Makefile (OBJS): New object file, chksums/md5.o.
* chksum.c (sha256_ensure_buf): Renamed to chksum_ensure_buf
and made generic so MD5 code can borrow it.
(sha256_stream, sha256): Call chksum_ensure_buf instead of
sha256_ensure_buf, passing in new length and hash name
parameters.
(md5_stream_impl, md5_buf, md5_str): New static functions.
(md5_stream, md5): New functions.
(chksum_init): Register md5-stream and md5 intrinsics.

This test will misbehave on TXR without the previous fix;
it will not collect columns of data which keep the
corresponding rows items together.

* Makefile (tst/tests/001/query-5.ok): Pass -B to txr for this
new test.
* tests/017/glob-carray.expected: Updated, because the glob
test globs over the contents of tests/001 directory.

functions.
* chksums/crc32.c, chksums/crc32.h: New files.

When the build is being done in the source directory, allow
the configure script to be executed via path names other than
just ./configure, such as an absolute path.
Some distros use this.
* configure (build_in_srcdir): New variable.
(inode): New function.
Rather than checking whether "$source_dir" is ".", we test
whether they are the same inode. If they are the same, we now
also set the build_in_srcdir variable in addition to
generating the usual warning.
(gen_config_make): Propagate the build_in_srcdir into
config.make.
* Makefile: use the build_in_srcdir variable from config.make
to determine whether we are building in the source directory,
rather than relying on top_srcdir being blank.
|
|
|
|
|
|
| |
* Makefile (dbg/%-win.o, opt/%-win.o): Don't pass
CONFIG_WIN_MAIN=1 preprocessor symbol; it's not referenced
anywhere, and never has been.

After the defvar bugfix in the previous commit, the only
differences between .tlo and .tlo2 files are the names of
a few gensyms here and there. In other words, they are
identical code; therefore, there is no point in compiling
them.
* Makefile (STDLIB_TLOS2): Variable removed.
(%.tlo2): Implicit rule removed.
(stage1 stage2): Phony targets removed.
(all): Directly depends on $(STDLIB_TLOS) without stage1
intermediary.
(clean-tlo): Don't remove $(STDLIB_TLOS2).
|
|
|
|
|
|
|
|
| |
* Makefile (install): Drop the $(top_srcdir) prefix from
share/txr/stdlib materials. This fails for the .tlo files
which are only found in the build directory, not the source
directory. The .txr and .tl files are found in both, thanks
to symlinks; for those it works either way.
|
|
|
|
| |
* Makefile (MPI_OBJ_BASE): remove mplogic.o.

* Makefile (opt/txr.o, dbg/txr.o): Set up TXR_REL_PATH
preprocessor symbol on command line which specifies the
hard installation path derived from the configure prefix.
* txr.c (get_self_path): The fallback implementation simply
returns TXR_REL_PATH. This will work if in fact the executable
is installed at that path. What it means is that the build of
TXR which uses this fallback get_self_path will not support
relocation: the installation cannot be moved to another
directory, yet still find its supporting files. This is
better than what we are replacing: not working even in the
original installation directory, if not invoked by an absolute
path.
|
|
|
|
|
|
|
|
|
| |
* Makefile: make STDLIB_EARLY_TLOS order-only prerequisites of
STDLIB_LATE_TLOS, rather than conventional prerequisites.
This means that the early tlo-s are built or rebuilt
before the late ones, but there is no other dependency
expressed: an update of early tlo-s doesn't force late tlo-s
to be out-of-date and updated also.

On newer GNU Make versions, $(wildcard ...) doesn't sort
its results, and so we compile .tlo files in an
arbitrary order. For the most part, this is fine.
However, there is a complicated circular dependency involving
the error.tl file requiring it to be compiled first.
* Makefile (STLIB_EARLY_PATS, STDLIB_EARLY_TLOS,
STDLIB_LATE_TLOS): New variables. Use these
to express a dependency which causes error.tlo
to be built first.

The GNU Bison parser has a GPL header in the parser skeleton
which gets copied to the generated parser. The GPL asserts
that the entire file falls under the GPL (but as a special
exception, it may be used in any manner whatsoever in a
program, as long as it isn't used as the skeleton of a parser
generator). The GPL assertion is false; the file is not
entirely derived from the skeleton but contains code directly
copied from parser.y, as well as tables generated from
parser.y's original grammar. Since we are definitely not using
this as a parser skeleton for a parser generator and are thus
allowed to do whatever we want such as compiling this into
proprietary object files, I'm removing the copyright header as
a build step. You never know; someone could package up a built
directory of TXR containing a Bison-generated y.tab.c, and
then it looks like there is a GPL-ed file in the project.
* Makefile (CM): New variable, needed for interpolating
literal commas into macro calls.
(BS_LIC_FROM, BS_LIC_TO): New variables.
(y.tab.c): Filter y.tab.c to remove GPL comment.
|
|
|
|
|
|
|
|
|
|
| |
* Makefile (SH): The $(1) macro argument is substituted into
a shell '...' quote. It may contain single quotes itself,
so these have to be mapped to the famous '\'' sequence.
Currently, only one SH call has '...' syntax in it: one
in the y.tab.c rule which calls sed -e '/yyparse/d'.
That works anyway, and the quotes could be removed from
it; but let's fix the SH macro.
|
|
|
|
|
|
|
|
| |
* Makfile (%.tlo, %.tlo2): We take advantage of Gmake's
order-only prerequisites to express this dependency. This
means that .tlo and .tlo2 files are not considered outdated
when $(PROG) is newer; it only ensures that $(PROG) cannot
be missing when a .tlo or .tlo2 must be updated.
|
|
|
|
|
|
| |
* Makefile: add .NOTPARALLEL: special target.
This Makfile doesn't support parallel builds; it relies
on left-to-right execution of prerequisites in some places.
|
|
|
|
|
|
|
|
| |
* Makefile (%.tlo, %.tlo2): Drop dependency on $(TXR).
Of course, the dependency is strictly correct, but most
changes to TXR are irrelevant. Moreover, not all relevant
dependencies are in place anyway; if we change compile.tl,
only the compile.tlo is recompiled.

Another part of the preparation for an upcoming change.
All library code is now read in the sys package, so any
symbols that are interned (local variables and whatnot)
are in sys and will not be exposed to user code.
We have to overcome some annoyances to achieve this:
- We have to stay away from the symbols exp or var,
because they are now sys:exp and sys:var with their
special meaning.
- Instances in which a symbol of the same name exists
in both sys and usr present a problem; the plain
symbol now is the usr one. For instance rplaca
will refer to sys:rplaca, so a small amount of
code has to explicitly use usr:rplaca.
* Makefile (COMPILE_TL): Change to the sys package before
compiling library code.
* lisplib.c (lisplib_try_load): Bind *package* to the system
package.
* share/txr/stdlib/asm.tl, share/txr/stdlib/compiler.tl:
Remove in-package macro invocation; we don't need this since
all files are loaded or compiled in the sys package.
* share/txr/stdlib/build.tl, share/txr/stdlib/cadr.tl,
share/txr/stdlib/conv.tl, share/txr/stdlib/doloop.tl,
share/txr/stdlib/error.tl, share/txr/stdlib/error.tl,

This commit is the start of compiler work to make TXR Lisp
execute faster. In six days of part time work, we now have a
register-style virtual machine with 32 instructions, handling
exceptions, unwind-protect, lexical closures, and global
environment access/mutation. We have a complete assembler and
disassembler for this machine. The assembler supports labels
with forward referencing with backpatching, and features
pseudo-ops: for instance the (mov ...) pseudo-instruction
chooses one of three kinds of specific move instruction based
on the operands.
* Makelfile (OBJS): Add vm.o.
* eval.c (lookup_sym_lisp1): Static function becomes external;
the virtual machine needs to use this to support that style
of lookup.
* genvmop.txr: New file. This is the generator for the
"vmop.h" header.
* lib.c (func_vm): New function.
(generic_funcall): Handle the FVM function type via new
vm_execute_closure function. In the variadic case, we want
to avoid the argument copying which we do for the sake of C
functions that get their fixed arguments directly, and then
just the trailing arguments. Thus the code is restructured a
bit in order to switch twice on the function type.
(init): Call vm_init.
* lib.h (functype_t): New enum member FVM.
(struct func): New member in the .f union: vm_desc.
(func_vm): Declared.
* lisplib.c (set_dlt_entries_impl): New static function,
formed from set_dlt_entries.
(set_dlt_entries): Reduced to wrapper for
set_dlt_entries_impl, passing in the user package.
(set_dlt_entries_sys): New static function: like
set_dlt_entries but targetting the sys package.
(asm_instantiate, asm_set_entries): New static functions.
(lisplib_init): Auto-load the sys:assembler class.
* share/txr/stdlib/asm.tl: New file.
* vm.c, vm.h, vmop.h: New files.
