* c_num: now takes self argument.Kaz Kylheku2020-06-291-59/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The c_num and c_unum functions now take a self argument for identifying the calling function. 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.

* Reduce footprint of :fd property.Kaz Kylheku2020-04-251-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Querying the :fd stream property is equivalent to calling the stream-fd function. Streams have a C virtual function get_fd, so implementing :fd in their getprop functions is redundant functionality. The stream-getprop function can test for :fd and call stream-fd, so the stream implementations don't have to deal with the :fd property. Also, there are still places in the code base that are using stream_getprop to get the file descriptor, instead of calling stream_fd. If we fix all this, then fd_k remains referenced only in a very small number of places. * socket.c (dgram_get_prop): Don't handle :fd any more. * stream.c (unimpl_get_fd): Static function removed. (fill_stream_ops): Default the get_fd function to null_get_fd instead of unimpl_get_fd, so it doesn't throw. Even a stdio stream don't throw; when the file is closed, it returns nil. (stdio_get_prop): Don't handle :fd any more. (stream_get_prop): Handle :fd here. If the stream has a get_fd function that isn't null_get_fd, then call it. Only if the stream doesn't have a get_fd function, fall back on its get_prop function. * sysif.c (mkdir_wrap, poll_wrap, simulate_setuid_setgid): Call stream_fd instead of stream_get_prop.
* sockets: connect bugfix and use poll in preference to select.Kaz Kylheku2020-04-231-35/+71
| | | | | | | | | | | | | | | * configure: cosmetics: change HAVE_SYS_SELECT to HAVE_SELECT, and log that the function rather than the header is being detected. * socket.c (fd_timeout): New function, implemented using poll or select. (to_connect): select logic replaced with fd_timeout. Bug fixed: connect requires polling for writability, not readability. If poll and select are not available, ignore timeout argument. (sock_accept): Use fd_timeout; fall back on non-timed-out accept if poll or select not available.
* sockets: missing shut-rd, shut-wr, shut-rdwr.Kaz Kylheku2020-04-131-0/+3
| | | | | | | | | | | | * socket.c (sock_load_init): Register documented but completely missing intrinsic variables shut-rd, shut-wr, shut-rdwr. * lisplib.c (sock_set_entries): Register autoload for shut-rd, shut-wr, shut-rdwr. * txr.1: In sock-shutdown description, fix shut-rw typo that should be shut-wr.
* open-socket-pair: bugfix.Kaz Kylheku2020-04-131-5/+7
| | | | | | * socket.c (socketpair_wrap): Don't close descriptors unconditionally in unwind case; only if the list to be returned has not been created.
* warning cleanup: GNU C++ initializer warnings.Kaz Kylheku2020-04-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This is the eight and final round of an effort to enable GCC's -Wextra option. The C++ compiler, with -Wextra, doesn't like C's universal struct initializer { 0 }, individually complaining about all the remaining members not being initialized. What works in C++ is the { } initializer. Conditional definition to the rescue. * lib.h (all_zero_init): New macro which expands to { } under C++, and { 0 } under C. * lib.c (make_time_impl, epoch_tm, time_string_meth, time_parse_meth): Use all_zero_init. * parser.c (prime_parser): Likewise. * socket.c (sock_mark_connected): Likewise. * sysif.c (fcntl_wrap): Likewise. * termios.c (encode_speeds, decode_speeds): Likewise. * configure (diag_flags): Add -Wextra.

| | | | | | | * socket.c (getaddrinfo_wrap): Initialize alist to null, because getaddrinfo doesn't set it in the failure case! Then, avoid calling freeaddrinfo for null pointer; POSIX doesn't require that to work.
* Fix memory leak in dgram socket streams.Kaz Kylheku2016-06-081-0/+1
| | | | | * socket.c (dgram_destroy): Free the dgram_stream structure too, not just its buffers.
* Use width of 8 for struct dgram boolean bitfields.Kaz Kylheku2016-05-291-2/+2
| | | | | | | | * socket.c (struct dgram): Members is_connected and is_byte_oriented widened from 1 to 8 bits. This allows byte-access instructions to be used on architectures like x86. All the flags still fit into a word, so the structure doesn't get bigger.
* Support byte oriented mode in dgram sockets.Kaz Kylheku2016-05-291-3/+19
| | | | | | | | | * socket.c (struct dgram_stream): New member, is_byte_oriented.

If regex_compile were to throw an exception, that lexeme will leak. * socket.c (getaddrinfo_wrap): Harden against leakage of node_u8 and service_u8 strings with an unwind block. For instance, the hints structure could contain bad values which cause addrinfo_in to throw. * stream.c (make_string_byte_input_stream): Perform possibly throwing argument conversions before allocating resources. * sysif.c (mkdir_wrap, mknod_wrap, chmod_wrap, symlink_wrap, link_wrap, setenv_wrap, crypt_wrap): Likewise. * syslog.c (openlog_wrap, syslog_wrapv): Likewise.
* Recycle conses in unget-char and read-until-match.Kaz Kylheku2016-04-201-1/+1

Adding additional logic to completely recycle the stack. * socket.c (dgram_get_char): Use rcyc_pop to get the character from the push-back list. * stream.c (stdio_get_char): Likewise.
* Allow unlimited character pushback in unget-char.Kaz Kylheku2016-04-191-11/+4
| | | | | | | | | | | | | | | | Fixing read_until_match will require this feature. * socket.c (dgram_get_char): Treat unget_c as a cons-based stack; pop a character from it if available. (dgram_unget_char): Push the character onto unget_c rather than storing the characer into unget_c. * stream.c (stdio_get_char, stdio_unget_char): Closely analogous changes to the ones in dgram_get_char and dgram_unget_char, respectively. * txr.1: Documentation improved and updated.
* Make open_socket static and register in socket.c.Kaz Kylheku2016-04-141-1/+2
| | | | | | | | | | | | | | * lisplib.c (sock_set_entries): Add auto-load entry for open-socket. * socket.c (open_socket): Change to static. (sock_load_init): Register open-socket intrinsic here rather than in stream.c. * stream.c (stream_init): Remove registration of open-socket intrinsic. * stream.h (open_socket): Declaration removed.

* Fix error handling in dgram case of sock-accept.Kaz Kylheku2016-04-141-10/+11
| | | | | | | * socket.c (sock_accept): Reduce scope of unwind catch around recvfrom call. Add missing check nbytes == -1. Branch to failed label in dup failed case, instead of throwing exception with truncated "unable to" message.
* Bugfix: support abstract UNIX socket addresses on Linux.Kaz Kylheku2016-03-311-2/+5
| | | | | | | | | | | | | Making it work as already documented. * socket.c (MIN): New macro. (sockaddr_pack): Use utf8_dup_to_buf to convert Unix socket path to a buffer of UTF-8 bytes, possibly with one or more embedded null bytes. Copy as much of this as fits into the sun_path member of struct sockaddr_un. * txr.1: Improve documentation about the abstract names on Linux.
* sock-set-peer shouldn't mark dgram sockets connected.Kaz Kylheku2016-03-311-1/+5
| | | | | | | | | | | | Merely setting a peer doesn't actually connect the socket, so it must not be marked connected. If it is wrongly marked connected, then dgram_flush will wrongly use send rather than sendto. * socket.c (dgram_set_sock_peer): Don't set sock_connected flag. (sock_connect): Set the sock_connected flag here, for dgram sockets.
* Rename badly named socket-related internal funs.Kaz Kylheku2016-03-311-16/+16
| | | | | | | | | | | | | | | Also rename its related functions for consistency. * socket.c (sockaddr_in_out): Renamed to sockaddr_in_unpack. The "in" stands for internet, and is juxtaposed to "out". (sockaddr_in6_out): Renamed to sockaddr_in6_unpack. (unix_sockaddr_out): Renamed to sockaddr_un_unpack. (getaddrinfo_wrap): Calls to *_out functions renamed to *_unpack. (sockaddr_in): Renamed to sockaddr_pack. Original name is confusing against the struct tag name in struct sockaddr_in. (dgram_set_sock_peer, sock_bind, sock_connect, sock_accept): Calls updated to sockaddr_pack.
* Permissive stream open mode strings.Kaz Kylheku2016-03-191-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is more to this patch than just more permissive mode strings. Now if a socket can be opened with mode "l2" for instance, and these options are effectively applied to the socket-specific "r+b" default, not to "r". * stream.c (parse_mode): New argument specifying a default mode. The syntax is relaxed, allowing previously required elements to be omitted. (normalize_mode): New argument specifying a default mode. Format mode is always called now, because an input string is no longer necessarily a valid fopen string even in cases when it doesn't specify any extensions. (open_file, open_fileno, open_tail, open_command, open_process): Use new normalize_mode argument for defaulting; normalize_mode no longer defaults to "r". * stream.h (stdio_mode_init_trivial): Macro removed. (stdio_mode_init_blank, stdio_mode_init_r, stdio_mode_init_rpb): New initializer macros. (parse_mode, normalize_mode): Declarations updated. * socket.c (sock_accept): In datagram socket case, use new parse_mode argument for defaulting using stdio_mode_init_rpb, rather than overriding a missing string with "r+b". (open_sockfd): Likewise, and use new normalize_mode argument similarly for defaulting the mode on a stream socket. * txr.1: Documented mode string permissiveness.
* Size mode meaningful in datagram sockets.Kaz Kylheku2016-03-191-11/+20
| | | | | | | | | | | | | | | | | | | | | | * socket.c (struct dgram_stream): new rx_max member. (make_dgram_sock_stream): New arguments: a struct stdio_mode, and pointer to prototype dgram socket. If a size is specified in the mode, then use that as rx_max. Otherwise if a prototype socket is specified, use its rx_max as the new socket's rx_max. Otherwise default on 65536. (dgram_get_byte_callback): Use d->rx_max as the capture size, rather than a hard-coded 65536. (sock_accept): Use d->rx_max as capture size for datagram. Parse the mode. Pass the parsed mode to make_dgram_sock_stream, as well as the accepting socket, so it can set up the rx_max for the new socket. (open_sockfd): Parse the mode and pass to make_dgram_sock_stream. * stream.c (parse_mode): Static function becomes extern. * stream.h (parse_mode): Declared. * txr.1: Documented.
* Nuke accidental tabs.Kaz Kylheku2016-03-191-9/+9

* Sockets are r+b by default, not r+.Kaz Kylheku2016-03-181-1/+1
| | | | | | * socket.c (open_sockfd): Default mode string is "r+b". * txr.1: Documented.
* Timeout parameter in sock-accept.Kaz Kylheku2016-03-151-7/+38
| | | | | | | | | | * socket.c (sock_accept): New third parameter specifying timeout. If a timeout is specified, use the select function to select socket for reading, datagram or stream. (sock_load_init): Update registration of sock-accept intrinsic to three arguments, one optional. * txr.1: Documented sock-accept's timeout parameter.
* Make connect interruptible and support timeout.Kaz Kylheku2016-03-151-3/+65
| | | | | | | | | | * socket.c (to_connect): New static function. (sock_connect): Use to_connect instead of calling connect directly. (lock_load_init): sock-connect intrinsic registration updated to three arguments, one optional. * txr.1: Documented sock-connect timeout.
* Implement socket timeouts.Kaz Kylheku2016-03-151-0/+35
| | | | | | | | | | | | | | | | | * lib.c (timeout_error_s): New symbol variable. (obj_init): Intern timeout-error, init new variable. * lib.h (timeout_error_s): Declared. * socket.c (sock_timeout, sock_send_timeout, sock_recv_timeout): New static functions. (sock_load_init): Register sock-send-timeout and sock-recv-timeout intrinsics. * stream.c (stdio_maybe_read_error, stdio_maybe_error): Convert EAGAIN into timeout_error_s. * txr.1: Documented.
* sock-connect return value change.Kaz Kylheku2016-03-141-1/+1
| | | | | | | * socket.c (sock_connect): return a useful value rather than t, namely the socket. * txr.1: Documented.
