* solaris: disable failing test case.Kaz Kylheku2021-08-261-0/+4
| | | | | | | * tests/007/except-4.txr: This new test case does not work on Solaris 10 because a shell script that kills itself via kill $$ appears to be terminating successfully with an exit status of 208, not appearing to be killed by a signal.
* mmap tests: BSD patch.Kaz Kylheku2021-08-251-1/+2
| | | | | | * tests/017/mmap.tl: On BSD, the map-anon test case where we don't specify map-private or map-shared doesn't result in an invalid argument error; a mapping is produced.
* ffi: provide mmap through carray.Kaz Kylheku2021-08-221-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure: configure test for mmap depositing HAVE_MMAP into config.h. * ffi.c (struct carray): Subject to HAVE_MMAP, new mm_len member which keeps track of the size of an underlying mapping so that we can unmap it, as well as peform operations like msync on it. (make_carray): Initialize mm_len to 0. (MAP_GROWSDOWN, MAP_LOCKED, MAP_NORESERVE, MAP_POPULATE, MAP_NONBLOCK, MAP_STACK, MAP_HUGETLB, MAP_SHARED, MAP_PRIVATE, MAP_FIXED, MAP_ANON, MAP_HUGE_SHIFT, MAP_HUGE_MASK, PROT_READ, PROT_WRITE, PROT_EXEC, PROT_NONE, PROT_GROWSDOWN, PROT_GROWSUP, MADV_NORMAL, MADV_RANDOM, MADV_SEQUENTIAL, MADV_WILLNEED, MADV_DONTNEED, MADV_FREE, MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK, MADV_MERGEABLE, MADV_UNMERGEABLE, MADV_HUGEPAGE, MADV_NOHUGEPAGE, MADV_DONTDUMP, MADV_DODUMP, MADV_WIPEONFORK, MADV_KEEPONFORK, MADV_HWPOISON, MS_ASYNC, MS_SYNC, MS_INVALIDATE): #define as 0 if missing.

(mprotect_wrap, madvise_wrap, msync_wrap): New functions. (ffi_init): Register mmap, munmap, mprotect, madvise and msync as well as numerous integer variables: map-growsdown, map-locked, map-noreserve, map-populate, map-nonblock, map-stack, map-hugetlb, map-shared, map-private, map-fixed, map-anon, map-huge-shift, map-huge-mask, prot-read, prot-write, prot-exec, prot-none, prot-growsdown, prot-growsup, madv-normal, madv-random, madv-sequential, madv-willneed, madv-dontneed, madv-free, madv-remove, madv-dontfork, madv-dofork, madv-mergeable, madv-unmergeable, madv-hugepage, madv-nohugepage, madv-dontdump, madv-dodump, madv-wipeonfork, madv-keeponfork, madv-hwpoison, ms-async, ms-sync, ms-invalidate, page-size. * ffi.h (mmap_wrap, munmap_wrap, mprotect_wrap madvise_wrap, msync_wrap): Declared. * tests/017/mmap.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* sub: allow generic iterables.Kaz Kylheku2021-08-221-0/+19
| | | | | | | | | | | | | | | | In this patch we allow the s in (sub s from to) and [s from..to] to be any iterable. * lib.c (iter_dynamic, sub_iter): New static function. (generic_funcall): Handle all objects via the sequence case: ref, sub and all that. Unfortunately, we lose some error handling at the level of the sub function. But we allow any iterable to be passed through to sub. (sub): Handle default case through sub_iter. * tests/012/iter.tl: New cases. * txr.1: Documented.
* iter-begin: string range support.Kaz Kylheku2021-08-221-0/+42
| | | | | | | | | | | | | | Ranges like "AAA".."ZZZ" are now possible. * lib.c (seq_iter_get_range_str, seq_iter_peek_range_str, seq_iter_get_rev_range_str): New static functions. (seq_iter_init_with_info): Support string ranges via above new functions. Range direction test is now done with less and equal rather than lt and gt. * tests/012/iter.tl: New file. * txr.1: Documented.
* matcher: rename error-throwing macros.Kaz Kylheku2021-08-191-5/+5
| | | | | | | | | | | | | | | * stdlib/match.tl (must-match): Renamed to just match. It's just when-match without the "when". (must-match-case): Renamed to match-ecase, consistent with the case -> ecase naming scheme. * lisplib.c (match_set_entries): Names updated here. * tests/011/patmatch.tl: Test cases updated. * txr.1: Names updated here. * stdlib/doc-syms.tl: Updated.
* ffi: fix broken deffi support for variadic functions.Kaz Kylheku2021-08-172-0/+7
| | | | | | | | * stdlib/ffi.c (sys:analyze-argtypes): Add missing fallback case in filtering loop. This wouldn't have happened if we had a ecaseql macro, and used it. Or if we had coverage of this in tests. * tests/017/variadic.tl, tests/017/variadic.expected: New files.
* format: bug: sign not reset before each conversion.Kaz Kylheku2021-08-161-0/+4
| | | | | | | | | | | | | | | | | | For instance, this bad output is produced: (pic "+0####.## <<<<<" 123 1) -> "+00123.00 +1 " The second argument should not have any leading + sign. * stream.c (formatv): For each new conversion specifier introduced by ~, reset the sign variable to zero also. That's the semantic change here, occluded by the fact that I'm rearranging the declaration of the variables, adding comments, and condensing the assignments while also getting them into the same order as the declarations, in order that this sort of bug does not creep in in the future, should another such variable be added. * tests/018/format.tl: Adding correct version of above test case.
* matcher: new must-match and must-match-case macros.Kaz Kylheku2021-08-131-0/+9
| | | | | | | | | | | | | * lisplib.c (match_set_entries): Intern the match-error symbol. Register autoloads for must-match and must-match-case. * stdlib/match.tl (match-error): Register exception symbol, as subtype of match-error. (must-match, must-match-case): New macros. * tests/011/patmatch.tl: Test cases. * txr.1: Documented.
* tests: support BSD flavors loosely, not just OpenBSD.Kaz Kylheku2021-08-135-5/+5
| | | | | | | | | | | | * tests/common.tl (os-symbol): Look for the substring BSD in the system name, and map to symbol :bsd. Do not produce the :openbsd symbol. * tests/014/socket-basic.tl: Refer to :bsd, not :openbsd. * tests/017/glob-carray.tl: Likewise. * tests/018/chmod.tl: Likewise.
* int-str: 0x bug.Kaz Kylheku2021-08-131-0/+50
| | | | | | | | | | | | | | | * lib.c (int_str): The problem here is that we are recognizing and skipping the 0x prefix for all bases. So for instance (int-str "0x123") produces 123. The correct requirement, and the intent of the code, is that the C conventions are only honored if the base is specified as the character #\c. In any other base, including omitted base defaulting to 10, a leading zero is just a leading zero, and 0x is a zero followed by the junk character x. Therefore, if we have any valid base that isn't #\c, and 0x has been seen, we must return zero. We must not do this only in the base 16 case. * tests/016/conv.tl: New file.
* parser: @(mdo) must not be subject to expand-meta.Kaz Kylheku2021-08-111-0/+7
| | | | | | | | | | | | | | | | | | | | * parser.y (elem): When the elem is a list, if it starts with mdo, then we evaluate it immediately and substitute (do) as the semantic value. We no longer not allow mdo to precipitate into match_expand_elem, where expand_meta will be unleashed on it. Doing so causes the bug that expessions like @1, denoting the form (sys:var 1), are rewritten to (sys:expr 1), which op syntax. So two bugs are fixed: the incorrect treatment of meta-syntax, and the neglect to perform mdo in nested contexts. (check_parse_time_action): We need not handle mdo here any more; it will never make it into this function. Only actions done in the main clause list belong here, not parse time actions done at any nesting level. * tests/008/mdo.txr: New file. * y.tab.c.shipped: Updated.
* txr: add tests for :nothrow handling process death.Kaz Kylheku2021-08-074-0/+12
| | | | | | | | | | * tests/007/except-3.txr: New file. * tests/007/except-3.expected: Likewise. * tests/007/except-4.txr: Likewise. * tests/007/except-4.expected: Likewise.
* windows: skip test requiring full Unicode.Kaz Kylheku2021-08-071-0/+3
| | | | | * tests/012/cont.tl: Exit before the test case that contains characters ouside of the BMP, if (sizeof wchar) is less than 4.
* txr: @(eof) takes argument for binding termination status.Kaz Kylheku2021-08-052-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We extend the matching context structures to keep track of the underlying stream from which lines are being taken via the lazy list. Then the implementation of the @(eof) directive, when it hits the eof condition, can use this stream to gain access to the termination status. * match.c (match_line_ctx, match_files_ctx): New member, stream. (ml_all): Take stream argument and initialize new member. (h_call, do_match_line): Pass stream argument to h_call. (mf_all, mf_file_data): Take stream argument and initialize new member. (mf_from_ml): Propagate stream from line context to file context. (freeform_prepare, v_next_impl, match_filter, match_fun, extract): Pass stream argument where now needed. (v_eof): Implement termination status binding via the stream stored in the context. (open_data_source): Store stream in match files context. * tests/010/eof-status.txr: New file. * tests/010/eof-status.expected: New file. * Makefile (tst/tests/010/eof-status.ok): -B option for new test. * txr.1: Documented eof directive, argument and all. * stdlib/doc-syms.tl: Updated.
* tests: fix undefined variable warning.Kaz Kylheku2021-08-031-1/+3
| | | | | * tests/012/oop.tl: Adjust one recently added test case to eliminate undefined variable warning.
* oop: fix infelicity in new* and lnew* macros.Kaz Kylheku2021-07-311-0/+14
| | | | | | | | | | * stdlib/struct.tl (sys:new-expander): If the argument of new* or lnew* is dwim, then treat that as an expression, rather than as a boa-style construction. * tests/012/oop.tl: Tests for new* focusing on this issue. * txr.1: Documented.
* tests: multiple evaluation issue in amb.Kaz Kylheku2021-07-301-2/+2
| | | | | | | | | | | | | | | | This issue doesn't affect the tests. This is for the benefit of someone who happens to be copy-and-pasting the amb implementation from here. * tests/012/cont.tl (amb): This function has an issue in that it calls the continuation (future calculation) and then if that succeeds, it normally returns the value. This means that the future is executed again. In the case of N amb expressions, the successful future is executed 2**N times. What amb must do is this: call the continuation and capture the value. If the value is successful, then that is the master return value; just return that from amb-scope, bypassing the second re-execution of the future.
* tests: longer test for delimited continuations.Kaz Kylheku2021-07-301-0/+10
| | | | | * tests/012/cont.tl: New test case. This aborts prior to recent gc fixes.
* parser: allow trailing commas in json, via opt-in flag.Kaz Kylheku2021-07-291-0/+17
| | | | | | | | | | | | | | | | | | | | | | | * parser.c (read_bad_json_s): New symbol variable. (parser_common_init): Propagate value of *read-bad-json* into read_bad_json flag in parser structure. (parser_init): Initialize read_bad_json_s and register the *read-bad-json* dynamic variable. * parser.h (struct parser): New member, read_bad_json. (read_bad_json_s): Declared. * parser.y (json_val): Support an opt_comma symbol just before the closing bracket or brace. (opt_comma): New nonterminal symbol. Recognizes ',' or nothing. Error is flagged if ',' is recognized, and *read-bad-json* is nil. * y.tab.c.shipped: Updated. * tests/010/json.tl: New tests. * txr.1: Documented.
* subtypep: handle struct type objects.Kaz Kylheku2021-07-271-0/+48
| | | | | | | | | | | | | The subtypep function has poor requirements, handling only type symbols. Let's extend it to handle structure type objects. * lib.c (subtypep): In all cases when an argument is considered to be a possible structure symbol, and thus subject to find_struct_type, consider whether it already is a struct type, and just take it as-is. * tests/012/type.tl: New tests. * txr.1: Updated.
* pure-rel-path-p: add tests.Kaz Kylheku2021-07-221-0/+23
| | | | * tests/018/path.tl: New tests.
* op: set nested flag in correct context.Kaz Kylheku2021-07-191-0/+11
| | | | | | | | | | | | * stdlib/op.tl (sys:op-meta-p): Return an extended Boolean value: a true result is an integer indicating the depth of the variable. For instance @1 is depth 0, @@1 is depth 1 and so on. (sys:find-parent): New function. (sys:op-alpha-rename): When processing a nested meta, do not set the nested flag in the immediate parent. Use find-parent to go up to the correct level to which the meta belongs and set the flag there. * tests/012/op.tl: New test cases which depend on this.
* op: fix bug in do.Kaz Kylheku2021-07-191-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The June 30 09e70c914ca83b5c7405aa633864db49f27efa05, subject "op: refactor do handling", introduced a regression breaking the tags.tl program. An implicit argument gets inserted twice: [[(do op list @1)] 'x] -> (x x) ;; incorrect/weird This was spotted by Paul A. Patience while working on extending tags.tl for Emacs. It's not exactly a regression because the original behavior is not documented or tested, and has issues; we simply cannot roll back the commit; a proper fix is required. How the above call is now supposed to work is that: - the @1 parameter belongs to the op, not to the do. - the do therefore has no explicitly given parameters of its own. - therefore the do inserts its parameter. In other words (do op list @1) is formally equivalent to (do op list @1 @@1). Both levels of function indirection require an argument: [[(do op list @1) 'x] 'y] -> (y x) [[(do op list @1 @@1) 'x] 'y] -> (y x) * stdlib/op.tl (sys:op-ctx): The structure gets a new slot, nested, which is a flag indicating whether unprocessed nested metas occur. This is critically needed because the sys:op-alpha-rename passes which are called with do-nested-metas being false do not insert nested metas into the gens list; they transform them and leave them in the syntax. Yet we must make decisions based on their presence. Conretely, we must be able to tell that (do op list @@1) has a meta against the outer (do ...), while we are just processing the do. (sys:op-alpha-rename): When replacing a nested meta syntax with the macro invocation, we set the nested flag of the parent context true. (sys:op-expand): Bring back the do-gen; we need it. We cannot simply insert @1 into the syntax, because that is not lexically transparent. If we add @1 to (do op ...) then that @1 is interpreted as belonging to the op, not to the do. We must also check the new Boolean flag nested to properly detect whether we have metas, including unexpanded nested metas. * tests/012/op.tl: New test cases combining (do op ...).
* paths: new tests.Kaz Kylheku2021-07-151-0/+46
| | | | | * tests/018/path.tl: test coverage for abs-path-p and portable-abs-path-p.
* tests: fix stack overflow test case for old gmake.Kaz Kylheku2021-07-141-2/+7
| | | | | | | | | | | | | | | * tests/012/stack.tl: The (if stack-limited ...) test is not correct because even if gerlimit indicates an unlimited stack, we impose a defualt limit, and so (get-stack-limit) returns a an integer value. The idea here was to try to skip this test case when the stack usage is unlmited, which happens under older versions of GNU make, before posix_spawn was introduced. Instead, let's execute this test case only if we have setrlimit. In the forked child, we try to impose a small stack limit that will give use the stack overflow crash we are testing for. The objective of the test case is to validate that when (set-stack-limit 0) is called, the child will abort due to a signal, rather than (recur) returning :so.
* rand: support buffers as random seeds.Kaz Kylheku2021-07-131-0/+84
| | | | | | | | | * rand.c (make_random_state): Recognize buffer object as sources of bits for seeding. * tests/013/rand.tl: New file. * txr.1: Documented.
* tests: guix fixes.Kaz Kylheku2021-07-135-4/+11
| | | | | | | | | | | | | | | | * tests/002/query-1.txr: Skip test if an executable /bin/sh doesn't exist, rather than the bogus reasons. * tests/010/json.tl: Change the condition for the command-put-json tests: not whether cat is found in the search path but whether /bin/sh exists and is executable. * tests/017/realpath.tl: Also quit if /usr/bin doesn't exist. * tests/018/path-test.tl: Exit succesfully if /bin/sh does not exist. Revert the earlier change. * tests/018/process.tl: Quit if no executable /bin/sh exists.
* tests: weaken condition in path search for sh.Kaz Kylheku2021-07-121-1/+1
| | | | | | | * tests/018/path-test.tl: In the Guix build environment, the shell might be found at a path not ending in bin. Let's ust test for ending in /bin. Reported and investigated by Paul A. Patience.
* tests: json: skip tests relying on cat, if missing.Kaz Kylheku2021-07-121-7/+9
| | | | | | | * tests/010/json.tl: skip several test cases which rely on the cat utility for testing command-put-json, if the cat utility is not found in the search path. Reported and investigated by Paul A. Patience.
* tests: json: fix accidentally excluded tests.Kaz Kylheku2021-07-121-2/+2
| | | | | | * tests/010/json.tl: Fix several tests being excluded from the (mtest ...) form to which they are expected to belong, one of them having an extra quote in the expected value, too.
* tests: 002 group: skip test if utils missing.Kaz Kylheku2021-07-121-0/+2
| | | | | | * tests/002/query-1.txr: Terminate with status 13 if the needed utils cannot be found in the search path. Reported and investigated by Paul A. Patience.
* New function: add-suffix.Kaz Kylheku2021-07-101-0/+19
| | | | | | | | | | | * stream.c, stream.h (add_suffix): New function. (stream_init): add-suffix intrinsic registered. * tests/018/path.tl: Tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* New functions: trim-short-suffix, trim-long-suffix.Kaz Kylheku2021-07-101-0/+48
| | | | | | | | | | | | | | | * lib.c, lib.h (chk_substrdup): New function. * stream.c, stream.h (trim_short_suffix, trim_long_suffix): New functions. (stream_init): trim-short-suffix and trim-long-suffix intrinsics registered. * tests/018/path.tl: New tests. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* suffix functions: new test cases.Kaz Kylheku2021-07-101-1/+3
| | | | | * tests/018/path.tl: New cases covering dotted name situation, which is not a suffix, but can have a suffix.
* lib: tests for keep-if, remove-if, separate.Kaz Kylheku2021-07-101-0/+42
| | | | * tests/012/seq.tl: New tests.
* subtypep: handle COBJ inheritance.Kaz Kylheku2021-07-091-0/+20
| | | | | | | | | | | | | | | | | | * lib.c (class_from_sym): New static function. (subtypep): Remove special case handling of stream versus stdio-stream. If the two types are not both structures, then check whether they are both cobj classes. If so, check if they are in an inheritance relationship via the cobj_hash. (cobj_populate_hash): Map each symbol to a fixnum integer which gives class handle'position in the cobj_class table. (cobj_class_exists): Style: compare to nil instead of 0. (obj_init): Do not call cobj_populate_hash here, it is far too early: only a couple of COBJ types exist at this point. Moreover, hash_init has not been called so hash_cls and hash_iter_cls still have null symbols. (init): Call obj_populate_hash here, as the last step. * tests/012/type.tl: New file.
* with-resources: undocumented nil skip behavior.Kaz Kylheku2021-07-071-0/+18
| | | | | | | | | | | | | | | Paul A. Patience discovered the hidden "feature" of with-resourcers, that the three-argument form of the binding (var init cleanup) causes the with-resources form to terminate if init returns nil. The (var init) syntax doesn't generate this logic. * stdlib/with-resources.tl (with-resources): Do not emit the when form unless <= 265 compatibility is in effect. * tests/012/oop-mac.tl: New file. * txr.1: Compat note added.
* tests: fix malformed chmod.tl.Paul A. Patience2021-07-051-11/+11
| | | | | | * tests/018/chmod.tl (os): Fix final parentheses of defvarl form accidentally encompassing the rest of the source file. Replace tabs with spaces.
* genman, lib, tests: use defvarl where possible.Paul A. Patience2021-07-058-37/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * genman.txr (dupes, tagnum): Replace defvar with defvarl. * stdlib/doc-lookup.tl (os-symbol): Same. * tests/011/macros-3.tl (x): Same. * tests/011/mandel.txr (x-centre, y-centre, width, i-max, j-max, n) (r-max, pixel-size, x-offset, y-offset): Same. (file, colour-max): Delete (unused) variables. * tests/012/circ.tl (x): Replace defvar with defvarl. * tests/012/stack.tl (stack-limited): Same. * tests/012/struct.tl (s): Same. * tests/013/maze.tl (vi, pa, sc): Delete variables. Use function arguments instead. (usage): Fix typo. * tests/014/dgram-stream.tl (family): Rename to... (*family*): ...this. * tests/014/socket-basic.tl (socktype): Rename to... (*socktype*): ...this. (%iters%): Replace defvar with defvarl.
* stack-limit: bug: not handling RLIM_INFINITY.Kaz Kylheku2021-07-041-6/+9
| | | | | | | | | | | | | | | | * gc.c (gc_init): We must check rlim_cur for the RLIM_INFINITY value indicating unlimited stack, and not misuse this value as a limit number, otherwise hilarity ensues. This reproduced on an older platform with make 3.81, which calls setrlimit to bring about an unlimited stack, passed on to child processes. Because of this txr segfaulted, as a consequence of a false positive. * tests/012/stack.tl (stack-limited): New variable which indicates whether there is a stack limit. If there isn't, we avoid running the fork-based test case. Also, we set the stack limit to 32768 so we have a limit against which to run some of the tests.
* path-search: fix test for sh not being in /bin.Kaz Kylheku2021-07-041-1/+1
| | | | | * tests/018/path-test.tl: Check that the result of a path-search for "sh" only ends in "/bin/sh", not that it is precisely "/bin/sh".
* suffix functions: ignore trailing slashes.Kaz Kylheku2021-07-031-2/+16
| | | | | | | | | | | | | | | | Another requirements tweak to short-suffix and long-suffix: ignore one or more trailing slashes, instead of just one. This harmonizes with base-name, which does same, that requirement being copies from the POSIX basename utility. * stream.c (short_suffix, long_suffix): If sl points to a trailing slash which is the start of a suffix that consists of nothing but trailing slashes, then we pretend it isn't there. * tests/018/path.tl: Adjusted two existing test cases, and added more. * txr.1: Documented.
* compiler: add failing inline lambda tests.Kaz Kylheku2021-07-031-0/+10
| | | | | * tests/012/lambda.tl: Add tests where apply list supplies : values to optional params, which must trigger defaulting.
* tests: support for compiled test forms.Kaz Kylheku2021-07-032-23/+51
| | | | | | | | * tests/common.tl (*compile-test*): New variable. (vtest): Compile cases via compile-toplevel if *compile-test* is true, catching compile-time exceptions. * tests/012/lambda.tl: Set *compile-test* true and repeat file.
* tests: include constp test in compile case.Kaz Kylheku2021-07-021-1/+1
| | | | * tests/012/compile.tl: Add const.tl file.
* tests: simplify file name handling in compile test.Kaz Kylheku2021-07-021-5/+5
| | | | | * tests/012/compile.tl: Remove suffixes from name list, and simplify code.
* lambda: tests.Kaz Kylheku2021-07-021-0/+88

* op: bug in do: must insert @1 into unexpanded form.Kaz Kylheku2021-06-291-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case when the do syntax has no metavariables, and it expands as-is without the addition of symbol in the tail position, we are doing something wrong: we are adding the @1 into the expanded version of the form, rather than the original. For instance: 1> (expand '(do pop a)) (lambda (#:arg-1-0017 . #:arg-rest-0016) (prog1 (car a) (sys:setq a (cdr a)) #:arg-1-0017)) Here, the @1 was inserted into the (prog1 ...) form which is the expansion of pop. This is incorrect; it must be inserted into the original (pop a) syntax as (pop a @1). * op.tl (op-expand): In this case when there are no metas and no do-gen that can be replaced by @1 via symacrolet, go back to the original args syntax, add the arg1 meta into that syntax, and process it from the beginning through parallel expansions steps. * tests/012/op.tl: Couple of tests added.
