| | | | | | | * parser.l (yyerrprepf): Replace wrong bare assignment to parser->prepared_msg with proper set macro which handles the mutation of a mature generation object such that it points to a baby object.
* Show failing address in sock-connect error.Kaz Kylheku2016-03-071-2/+2
| | | | | * socket.c (sock_connect): If connect fails, show socket and address in error message.
* Bugfix: incorrect error string from stdio streams.Kaz Kylheku2016-03-071-1/+1
| | | | | | | * stream.c (errno_to_string): Fix wrong test; it is a nil value of err which is the "no error" case, not non-nil. Due to this bug, any non-numeric error condition will be reported as "no error", including the case t ("eof").

* Fix in chk_manage_vec resizing from zero.Kaz Kylheku2016-03-061-1/+1
| | | | | | | * lib.c (bounding_pow_two): Eliminate bogus zero versus non-zero case check in return which causes the function to wrongly map 1 to 0, so that chk_manage_vec is then not able to adjust a vector to size 1.
* Replace stdio_get_line with generic routine.Kaz Kylheku2016-03-051-25/+23
| | | | | | | | | | * stream.c (snarf_line): Function renamed to generic_get_line. Interface and implementation changed so it can be used directly as get_line virtual. (stdio_get_line): Function removed. (stdio_ops, pipe_ops): Point get_line to generic_get_line. (tail_get_line): Call generic_get_line instead of stdio_get_line.

(strm_ops_init): Set new members to zero.
* Make make_sock_stream static in stream.c.Kaz Kylheku2016-03-042-4/+1
| | | | | | | * stream.c (make_sock_stream): External function becomes static; it is not used outside of this source file. * stream.h (make_sock_stream): Declaration removed.
* Support umask function.Kaz Kylheku2016-03-022-0/+30
| | | | | | | * sysif.c (umask_wrap): New function. (sysif_init): Register umask intrinsic. * txr.1: Documented.

* Doc: syslog-related fixes.Kaz Kylheku2016-02-281-4/+5
| | | | | | * txr.1: Refer to parameter as options, not option, and use .meta consistently. Don't refer to Syslog section in all caps.
* Doc: elsif doesn't exist.Kaz Kylheku2016-02-281-1/+1
| | | | * txr.1: replace nonexistent @(elsif) in example with @(elif).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * socket.c, socket.h: New files. * Makefile: include new socket.o among objects if have_objects variable is defined to 'y'. * configure (have_sockets): New variable. New configure test for socket-related functionality. (HAVE_SOCKETS, HAVE_GETADDRINFO): New configuration preprocessor symbols. Also, reordering the shell probing so that /usr/xpg4/bin/sh is the last fallback. On Solaris, it chokes on some code that is needed for Solaris. * lisplib.c (sock_set_entries, sock_instantiate): New static functions. (lisplib_init): Register new functions as autoload hooks. * share/txr/stdlib/socket.tl: New file. * stream.c (socket_error_s): New symbol variable.

| | | | | | | | | | | | | | | | | | | * lib.c (subtypep): Handle subtype check here between stream and stdio-stream as a special case, since streams aren't structures related by inheritance, but built-ins. (class_check): If the type of obj doesn't match the class exactly, use a subtypep check. We need this because stream functions use this check, and stdio streams are not of the stream type now. * stream.c (stdio_stream_s): New global symbol variable. (make_stdio_stream_common): Use stdio_stream_s symbol for the type of stdio streams. (stream_init): Intern the stdio-stream symbol, and store in stdio_stream_s variable. (streamp): Replace exact check with typep. * stream.h (stdio_stream_s): Declared.
* Functions for converting between buffers and integers.Kaz Kylheku2016-02-264-0/+60
| | | | | | | | | | | | | | | | | These functions convert between positive integers, and fixed-size memory buffers representing pure binary numbers in big endian byte order. This functionality will be used in some upcoming networking code. * arith.c (num_from_buffer, num_to_buffer): New functions. * arith.h (num_from_buffer, num_to_buffer): Declared. * mpi/mpi.c (mp_to_unsigned_buf): New function. * mpi/mpi.h (mp_to_unsigned_buf): Declared.
* Adding --eargs mechanism.Kaz Kylheku2016-02-022-2/+103
| | | | | | * txr.c (txr_main): Implement --eargs. * txr.1: Documented.
* Support lazy loading of stdlib struct definitions.Kaz Kylheku2016-01-311-2/+6
| | | | | | | * struct.c (make_struct_type): Use find_struct_type rather than direct lookup in struct_type_hash. (find_struct_type): Use lisplib_try_load if a type is not found to trigger autoloading on the symbol.
* Support setuid operation.Kaz Kylheku2016-01-234-1/+136
| | | | | | | | | | | | | | | | | | | | | * sysif.c (orig_euid, real_uid, repress_called, is_setuid): New static variables. (repress_privilege, drop_privilage, simulate_setuid): New functions. (RC_MAGIC): New preprocessor symbol. * sysif.c (repress_privilege, drop_privilage, simulate_setuid): Declared. * txr.c (txr_main): Call repress_privilege to check and remember whether we are in setuid mode, and temporarily drop the effective uid to the real one. (txr_main): Permanently drop privileges in all cases except script execution. In script execution cases, go through simulate_setuid to either set or preserve the effective user ID, or else drop privs. * txr.1: Documented setuid operation in new section.
* Add debug trace to @(require).Kaz Kylheku2016-01-221-1/+3
| | | | * match.c (v_require): Produce trace when require fails.
* Bugfix: @(require) eval not in proper env.Kaz Kylheku2016-01-221-2/+1
| | | | | | | | | I caught this when doing a @(require (boundp 'var)). * match.c (v_require): The correct evaluation was being done here, with the value discarded, followed by an incorrect evaluation in which the TXR bindings are not visible, whose value *is* then used.
* Semantics fix: unhandled exceptions must still unwind.Kaz Kylheku2016-01-222-36/+43
| | | | | | | | | | | | | | | | | * unwind.c (unhandled_ex): New static structure. (unwind_to_exit_point): The code to print the unhandled exception info and bail the process is moved here out of uw_throw. We do this in the situation when we have an unhandled exception, which is represented by the fact that the exception pointer points to the unhandled_ex structure. (uw_throw): If unhandled hook isn't a function, we don't abort; we go through the unwinding and unhandled processing. Also, ditto if the unhandled function returns, ditto. Unhandled processing is entered by substituting unhandled_ex for the not-found exception, and allowing unwind_to_exit point to be called. * txr.1: Document new behavior for unhandled exceptions and *unhandled-hook*.
* Header file cleanup.Kaz Kylheku2016-01-2217-44/+0
| | | | | | | * arith.c, cadr.c, debug.c, eval.c, filter.c, gencadr.txr, glob.c, hash.c, linenoise/linenoise.c, lisplib.c, match.c, parser.c, rand.c, regex.c, signal.c, stream.c, struct.c, sysif.c, syslog.c, txr.c, unwind.c, utf8.c: Remove unncessary header files.
* Reduce header pollution caused by mpi.h.Kaz Kylheku2016-01-224-7/+12
| | | | | | | | | | | | | * eval.c: include <assert.h> that was previously coming via "mpi.h". * mpi/mpi.c: Includes of <stdio.h>, <ctype.h> and <assert.h> moved here. * mpi/mpi.h: Remove include of <stdio.h>, <ctype.h> and <assert.h>. Keeping <limits.h> for now; needed for CHAR_BIT. * mpi/mplogic.c: Needs <assert.h>
* Version 133.txr-133Kaz Kylheku2016-01-216-560/+586
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
* Support for Base 64 encoding.Kaz Kylheku2016-01-213-1/+208

(base64_decode, base64_encode): New functions. (filter_init): Initialize new keyword symbol variables, and register base64-encode and base64-decode intrinsic functions. * filter.h (base64_encode, base64_decode): Declared. * txr.1: Documented base64-encode, base64-decode, as well as :tobase64 and :frombase64.
