* num_ex: eliminate ill-considered cast.Kaz Kylheku2022-01-061-1/+1
| | | | | | | * lib.h (num_ex): Remove the cast to ucnum, which will cause this macro to misbehave for negative arguments. For instance, -1 > (ucnum) INT_PTR_MAX will compare as true! The -1 gets converted to the unsigned type and becomes UINT_PTR_MAX.
* sysif: rlim constants: use signed/unsigned-agnostic macro.Kaz Kylheku2022-01-021-0/+2
| | | | | | | | | | | | * lib.h (num_ex): New macro. Uses unum if the argument is out of range for the signed type. Thus we can use this with unsigned constants that would wrap negative if passed to num. This is useful if some type in a system header file might be signed or unsigned. * sysif.c (sysif_init): Use num_ex for the RLIM_* constants. I'm observing values of -1 which should really be large, positive values in the rlim_t type, that being unsigned.

* gcc11: warnings related to struct args allocation..Kaz Kylheku2021-09-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As reported by Paul A. Patience, GCC 11 warns about situations in a few places where we do args_decl(args, 0) to allocate an absolutely empty argument list object. (This by the way, is only done in places where we are absolutely sure that the function we call will not be accessing the arguments. The usual rule is that there have to be at least ARGS_MIN arguments allocated, currently 4, and code relies on that being the case! So the places which call args_decl(args, 0) are coded carefully, checking that args is not passed anywhere where ARGS_MIN space is required.) Anyway, in the 0 case, the val arg[1] member of struct args is not allocated at all, because we call alloca(offsetof (struct args, arg)). Now GCC 11 notices this and complains that accesses to the other members like args->fill or args->list are using a struct that has not been entirely allocated. This, even though those members lie entirely within the allocated area. The fix for this is two faceted. Firstly, on C99, this diagnostic goes away if we make one simple change: declare the arg array as a flexible array member: val arg[]. However, we still support C90 in maintainer mode. So in maintainer mode, we stick with the 1. But we ensure that the places which call args_decl(args, 0) will pass 1 instead of 0, so the whole structure is allocated. * lib.h (FLEX_ARRAY): New macro: empty definition in C99 or later, otherwise 1. * args.h (struct args): Declare the size of the arg member using the new FLEX_ARRAY macro from lib.h. (ARGS_ABS_MIN): New macro, the absolute args minimum: zero in C99 mode, 1 in maintainer C90 mode. * ffi.c (ffi_struct_in, ffi_struct_get, make_zstruct): Use ARGS_ABS_MIN instead of 0 when preparing dummy args for make_struct call. * struct.c (struct_from_plist, struct_from_args, make_struct_lit): Use ARGS_ABS_MIN instead of zero when preparing dummy args for make_struct_impl or make_struct call.
* exceptions: hack to store errno in string object.Kaz Kylheku2021-09-071-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic idea: when we throw an exception that pertains to a system error which has an errno code, we can stick the errno into the memory area of the character string, into the wchar_t that immediately follows the null terminator. We can do this because strings track their actual allocation size. A pair of setter/getter functions to set and retrieve this value are provided, and all functions in the code which can set such a code are updated to do so, simply by calling the newly added uw_ethrowf that drop-in replaces for uw_throwf. * lib.[ch] (string_set_code, string_get_code): New functions. * unwind.[ch] (uw_ethrowf): New function. * eval.c (eval_init): Register string-set-code and string-get-code intrinsics. * ftw.c (ftw_wrap): Switch to uw_ethrowf. * parser.c (open_txr_file): Likewise. * socket.c (dgram_overflow): Store the ENOBUFS error in errno, and use uw_ethrowf instead uw_throwf. (dgram_get_byte_callback, dgram_flush, sock_bind, to_connect, open_sockfd, sock_connect, sock_listen, sock_accept, sock_shutdown, sock_timeout, socketpair_wrap): Switch to uw_ethrowf. * stream.c (dev_null_get_fd, stdio_maybe_read_error, stdio_maybe_error, stdio_close, pipe_close, open_directory, open_file, open_fileno, open_tail, fds_subst, open_subprocess, open_command, remove_path, rename_path, tmpfile_wrap, mkdtemp_wrap, mkstemp_wrap): Switch to uw_ethrowf. * sysif.c (mkdir_wrap, ensure_dir, chdir_wrap, getcwd_wrap, rmdir_wrap, mknod_wrap, mkfifo_wrap, chmod_wrap, do_chown, symlink_wrap, link_wrap, readlink_wrap, close_wrap, val exec_wrap, stat_impl, do_utimes, pipe_wrap, poll_wrap, getgroups_wrap, setuid_wrap, seteuid_wrap, setgid_wrap, setegid_wrap, setgroups_wrap, getresuid_wrap, setresuid_wrap, setresgid_wrap, crypt_wrap, uname_wrap, opendir_wrap, getrlimit_wrap, setrlimit_wrap): Likewise. * termios.c (tcgetattr_wrap, tcsetattr_wrap, tcsendbreak_wrap, tcdrain_wrap, tcflush_wrap, tcflow_wrap): Likewise. * tests/018/errno.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.

* string-extend: third optional argument.Kaz Kylheku2021-09-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A Boolean optional argument to string-extend indicates whether this is likely the last call to string-extend, so memory can be trimmed accordingly. * eval.c (eval_init): Update string-extend registration. * filter.c (trie_filter_string): Pass nil for new argument of string_extend. * lib.c (str_seq, replace_str, lazy_str_force, lazy_str_force_upto): Pass nil for new argument of string_extend. (rem_impl, remove_if, separate): Pass t for new argument of string_extend on last iteration, nil otherwise. (string_extend): Implement new third argument, defaulted to nil. Switch from chk_grow_vec to the more specific chk_wrealloc, which simplifies the code. * lib.h (string_extend): Declaration updated. * parser.y (litchars): Pass t as last argument of string_extend since we know syntactically that these reductions finalize the string. (restlitchar): Pass nil as the last argument of string_extend, since we know syntactically that it isn't the last. * regex.c (scan_until_common): Pass nil for new argument of string_extend. * txr.1: Documented.
* New function: delcons.Kaz Kylheku2021-09-021-0/+1
| | | | | | | | | | | | * eval.c (eval_init): Register delcons intrinsic. * lib.[ch] (delcons): New function. * tests/010/cons.tl: New file. * txr.1: Documented. * stdlib/doc-syms.tl: Updated.
* seq_iter: fix gc issues.Kaz Kylheku2021-08-291-1/+3
| | | | | | | | | | | | | | | | | | | | * lib.h (struct seq_iter_ops): New operation, mark. (seq_iter_ops_init): Default the mark operation to seq_iter_mark_op. (seq_iter_ops_init_nomark): New macro. * lib.c (seq_iter_mark_op): New static function. (si_range_cnum_ops, si_range_chr_ops, si_rev_range_cnum_ops, si_rev_range_chr_ops, si_chr_ops): Initialize with seq_iter_ops_init_nomark so that the iterator has no mark operation. All other iterator types have the above new static function as their mark op. (seq_iter_mark): Simplified: if the iterator has a mark op, call it. (seq_next, iter_step): If the iterator has a mark op, that means that the seq_get operation is likely replacing one heap object with another, and so mut(iter) must be called to inform the garbage collector of the assignment.
* seq_iter: refactoring.Kaz Kylheku2021-08-291-3/+9
| | | | | | | | | | | | | | | | | | | | | This is needed in preparation for fixing some gc bugs in iteration in a less hacky way. * lib.h (struct seq_iter): Members get and peek removed, replaced by ops pointer. (struct seq_iter_ops): New struct type. (seq_get, seq_peek): Call get and peek through ops table. * lib.c (seq_geti): Refer to get through ops. (si_null_ops, si_list_ops, si_vec_ops, si_hash_ops, si_tree_ops, si_range_cnum_ops, si_range_chr_ops, si_range_bignum_ops, si_range_str_ops, si_rev_range_cnum_ops, si_rev_range_chr_ops, si_rev_range_bignum_ops, si_rev_range_str_ops, si_chr_ops, si_num_ops, si_oop_ops, si_fast_oop_ops): New static structures. (seq_iter_init_with_info): Point new ops member of seq_iter to one of the new structures. Remove initializations of get and peek.

The default_arg_strict idiom is being used all over the stream library now. The common default value expressions like std_out are macros that access the dynamic variable by symbol. We don't want to be wastefully doing that on each stream operation, whether or not a stream argument has been supplied.

The struct type system allows struct types to be defined for symbols like regex or str, which are used by built-in or cobj types. This is a bad thing. What is worse, structure instances are COBJ types which identify their type using the COBJ class symbol mechanism. There are places in the C implementation which assume that when a COBJ has a certain class symbol, it is of a certain expected type, which is totally different from and incompatible form a struct instance. User code can define a structure object which will fool that code. There are multiple things going on in this patch. The major theme is that the COBJ representation is changing. Instead of a class symbol, COBJ instances now carry a "struct cobj_class *" pointer. This pointer is obtained by registration via the cobj_register function. All modules must register their class symbols to obtain these class handles, which are then used in cobj() calls for instantiation. The CPTR type was identical to COBJ until now, except for the type tag. This is changing; CPTR objects will keep the old representation with the class symbol. commit 20fdfc6008297001491308849c17498c006fe7b4 Author: Kaz Kylheku <kaz@kylheku.com> Date: Thu Jul 8 19:17:39 2021 -0700 * ffi.h (carray_cls): Declared. * hash.h (hash_cls): Declared.

I noticed the self names of these two are swapped; will fix in another commit. * eval.c (tprint): Refactor to use iterator framework for objects other than lists. The tree case falls into this, so trees are supported. * lib.h (enum seq_kind): New enum constant SEQ_TREELIKE. (seq_iter_init_with_info): Declared. * lib.c (seq_info): Map tree object to SEQ_TREELIKE type. (seq_iter_get_tree, seq_iter_peek_tree): New static functions. (seq_iter_rewind): Support rewinding tree iteration. I think we could reuse the existing iterator here, and in the hash case as well. I made a note to look into this. (seq_iter_init_with_info): Internal linkage changed to external, because tprint in eval.c uses this. Handle SEQ_TREELIKE case here, by setting up iterator with the two new static functions. (seq_iter_mark): Handle SEQ_TREELIKE_CASE. Change switch statement to exhaustively list cases. (ldiff): Add SEQ_TREELIKE to various cases. Idea is that we handle it like SEQ_HASH. (nsort, sort, nshuffle, take, take_while, take_until, drop_while, drop_until, update): Add case for SEQ_TREELIKE, routing to error message. (lazy_where_tree_func): New static function.

Alignment of wide literals test removed. Not generating LIT_ALIGN in config.h any more. * lib.h (LIT_ALIGN): Occurrences replaced with SIZEOF_WCHAR_T.

I don't see evidence that the claim in the commit is true: that wide literals are not four-byte-aligned on Darwin in spite of sizeof(wchar_t) being 4. Not even with the old clang in my old VM where I first thought I discovered this. * configure: do not set up LIT_ALIGN == 2 for Darwin. * lib.h (litptr): Remove LIT_ALIGN < 4 && SIZEOF_WCHAR_T == 4 case. * HACKING: Undocument bogus claim.

| | | | | | | | | | | | | | | | | | | | | | | | | That old cat-str function is often a pain, requiring the pieces as a list. We have a sys:fmt-join that is undocumented. That functions is now exposed as usr:join, and documented. Also introducing join-with that takes a separator as the leftmost argument. Thus (op join-with "::") gives us a function that joins pieces with :: in between. * eval.c (eval_init): Regiser fmt_join function under join symbol also. Register join-with. * lib.c (join_with): New function. (fmt_join): Now a wrapper for join_with that passes a nil separator. * lib.h (join_with): Declared. * share/txr/stdlib/optimize.tl (basic-blocks join-blocks): Rename the local function join, which now triggers a warning about a standard function being redefined. * txr.1: Redocumented cat-str, and documented join-with and join.
* lib: defend against locale-specific wcstod.Kaz Kylheku2021-03-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wcstod function has locale-specific behavior. It uses a locale-specific decimal separator character, which may not be the period. Though in TXR we never call setlocale in order to activate localization, it is a good idea to put in code to defend against this. If locale is ever unleashed on the code, it really botches our floating-point handling. However, let's keep that defensive logic disabled for now using the preprocessor. The strategy is to inquire about the locale's decimal character at startup. Then, in the flo_str function, we preprocess the input by converting the decimal period to the locale-specific character before calling wcstod. On the output side, we also deal with it in the format function; we call sprintf, and then convert the locale-specific characer to period. I tested all this by temporarily introducing the setlocale call, and switching to a locale with a comma as the separator, geting make tests to pass, and doing some interactive testing. This is not going to receive coverage in the test suite. * lib.c (dec_point): New global variable. (flo_str): If dec_point isn't '.', we must copy the string into a local buffer, which we get from alloca, and edit any '.' that it contains to dec_point. (locale_init): New function; initializes dec_point. (init): Call locale_init. * lib.h (dec_point): Declared. * stream.c (formatv): Don't look for a '.' in the result of printing a double using %e; look for dec_point. Post-process floating-point sprinf by substituting occurrences of dec_point with the period.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Makefile (OBJS): Add new time.o. * eval.c (eval_init): Registration of time functions is removed from here; it is done in time_init now, in time.c. * hash.c: Must #include "time.h" now. * lib.c (time_s, time_local_s, time_utc_s, time_string_s, time_parse_s, year_s, month_s, day_s, hour_s, min_s, sec_s, dst_s, gmtoff_s, zone_s): Variable definitions removed. These are now in time.c. Also declared in time.h. (time_sec, time_sec_usec, gmtime_r, localtime_r, string_time, time_string_local, time_string_utc, broken_time_list, tm_to_time_struct, broken_time_struct, time_fields_local, time_fields_utc, time_struct_local, time_struct_utc, time_fields_to_tm, time_struct_to_tm, make_time_impl, make_time, epoch_tm, strptime_wrap, time_parse, setenv, unsetenv, timegm_hack, make_time_utc, time_meth, time_string_meth, time_parse_meth, time_parse_local, time_parse_utc): Functions removed. These are now in time.c. (time_init): Removed, and now in time.c as an external function. * lib.h (time_sec, time_sec_usec, time_string_local, time_string_utc, time_fields_local, time_fields_utc, time_struct_local, time_struct_utc, make_time, make_time_utc, time_parse, time_parse_local, time_parse_utc): Declarations removed. Now in time.h. * rand.c: Must #include "time.h" now. * time.c: New file. * time.h: New file.
* New function: reject.Kaz Kylheku2020-09-011-0/+1
