* ftw: default flags to ftw-physKaz Kylheku2022-11-101-3/+3
| | | | | | | | | | | | | | | More often than not, you want the FTW_PHYS flag when calling the nftw function. Let's make that the default in TXR's wrapper. * ftw.c (ftw_wrap): Default to FTW_PHYS when flags argument not given, rather than zero, subject to compatibility option. (ftw_init): Don't check for FTW_PHYS with ifdef, since we relied on it being present. And anyway, any nftw implementation must have that. * txr.1: Documented.
* args: don't use alloca for const size cases.Kaz Kylheku2022-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * args.h (args_decl_list): This macro now handles only constant values of N. It declares an anonyous container struct type which juxtaposes the struc args header with exactly N values. This is simply defined as a local variable without alloca. (args_decl_constsize): Like args_decl, but requiring a constant N; implemented via args_decl_list. (args_decl_list_dyn): New name for the old args_decl_list which calls alloca. No places in the code depend on this at all, except the definition of args_decl. (args_decl): Retargeted to args_decl_list_dyn. There is some inconsistency in the macro naming in that args_decl_constsize depends on args_decl_list, and args_decl depends on arg_decl_list_dyn. This was done to minimize diffs. Most direct uses of args_decl_list have a constant size, but a large number of args_decl uses do not have a constant size. * eval.c (op_catch): Use args_decl_constsize. * ffi.c (ffi_struct_in, ffi_struct_get, union_out): Likewise. * ftw.c (ftw_callback): Likewise. * lib.c (funcall, funcall1, funcall2, funcall3, funcall4, uniq, relate): Likewise. * socket.c (sockaddr_in_unpack, sockaddr_in6_unpack, sockaddr_un_unpack): Likewise. * stream.c (formatv): Likewise. * struct.c (struct_from_plist, struct_from_args, make_struct_lit): Likewise. * sysif.c (termios_unpack): Likewise. * time.c (broken_time_struct): Likewise.

* exceptions: hack to store errno in string object.Kaz Kylheku2021-09-071-2/+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.

This requires changes in a large number of places. In a few places, additional functions acquire a self argument. The ffi module has the most extensive example of this. Some functions mention their name in a larger string, or have scattered literals giving their name; with the introduction of the self local variable, these are replaced by references to self. In the following changelog, the notation TS stands for "take self argument", meaning that the functions acquires a new "val self" argument. The notation DS means "define self": the functions in question defines a self variable, which they pass down. The notation PS means that the functions pass down an existing self variable to functions that now require it. * args.h (args_count): TS. * arith.c (c_unum, c_num): TS.

* Adding -D_GNU_SOURCE to compiler command line.Kaz Kylheku2016-05-011-3/+0
| | | | | | * configure (lang_flags): -D_GNU_SOURCE added. * ftw.c (__USE_GNU): Macro definition removed.
* Support list of paths in ftw.Kaz Kylheku2016-04-221-0/+12
| | | | | | | * ftw.c (ftw_wrap): Handle case when dirpath is a list, by recursion. * txr.1: Documented.
* ftw.c affected by g++/glibc issue __USE_GNU is defined.Kaz Kylheku2016-04-201-0/+2
| | | | | | | | | When compiling as C++, __USE_GNU is defined even though we use -ansi and don't specify -D_GNU_SOURCE anywhere. Glibc headers don't seem to respond to the C++ ANSI options. ftw.c: Workaround for compiler warning: only define __USE_GNU if it is not defined already.
* Adding ftw function.Kaz Kylheku2016-04-151-0/+177
* Makefile (ftw.o): Add to OBJS-y conditionally. * configure (have_ftw): New variable. New configure test for nftw. (gen_config_make): Set up have_ftw make variable. * ftw.c, ftw.h: New files. * lib.c (init): Call ftw_init, if compiled in. * txr.1: Documented.
