Commit fbf9f15b removed SO, SE, but left their declarations behind.
Ditto commit 3aea20e1 for bigcity_dchr, and commit 08b94556 for
player_kill_idle.
Commit afa65c8f accidentally added a declaration for xedit().
w32_writev_socket, w32_close_socket, getpass, w32_openfd,
w32_openhandle, w32_readv_handle, w32_close_handle,
sysdep_init, sysdep_stdin_init, w32_select, w32_signal_handler,
sigaction, stdin_read_thread, w32_ring_from_file_to_bounce_buf)
[_WIN32]: New w32 equivalent functions for POSIX functions.
(recvline, sendcmd, tcp_connect, hostconnect, getpass,
main, intr, play, ring_to_file, ring_from_file, doexecute,
doredir) [_WIN32]: Use new WIN32 equivalent functions.
(main) [_WIN32]: Add sysdep_init() to support system dependent
initialization for equivalence functions.
(play) [_WIN32]: Add sysdef_stdin_init() to support system
dependent initialization for reading stdin.
(recv_input, play) [_WIN32]: Replace the calls to ring_to_file()
and select() with WIN32 specific enhanced versions.
Makefile.in: update dependencies with new files.
Make.mk: Add using of getopt.c and getopt.h
from src/lib/w32 directory. Add getopt.c and getopt.h
to tar for client.
impossible to implement correctly, and nested execute practically
useless (#116377). Catch and refuse those:
(executing): New.
(doexecute, prompt): Set and clear it.
(redir_authorized): Reject if set.
(doexecute, play): Don't signal doexecute() failure through input_fd,
because that screws up up when we're executing already. Increment
send_eof in doexecute() instead.
(send_eof): External linkage.
(EOF_COOKIE, INTR_COOKIE, input_fd, send_intr, recv_output)
(recv_input, intr, play): New playing phase code. No native Windows
support yet. Sends just one EOF cookie on EOF on standard input
instead of up to three. Old servers (before recvclient.c rev. 1.16)
fail to terminate the session when they receive an EOF cookie at an
argument prompt. The session then hangs; use SIGINT to get out. No
longer blocks on sending input, which could deadlock the session.
Closes#827090. Fixes error handling for select(). Fixes race
condition that could cause server output to be discarded on EOF on
standard input.
(main): Replace old playing phase code by a call to play().
(intr, sock, interrupt, handleintr): Replaced by play(), remove.
[_WIN32] (hStdIn): Ditto.
(auxfp): New.
(servercmd, prompt, doexecute): Remove parameter auxfi, use auxfp.
(eight_bit_clean): Move to servcmd.c.
(servercmd): Work on a single non-C_DATA line instead of getting lines
from an ioqueue.
(servercmd, output, screen, outch): Deal with all ids in servercmd()
rather than some there and some in output(). Don't treat C_NOECHO,
C_ABORT, C_CMDERR, C_BADCMD specially. Fix C_FLASH and C_EXIT to
ignore redirections; they used to ignore them only for some parts.
Replace output() by outch(), fold screen into outch().
(servercmd): Truncate long prompts and telegram infos to prevent
buffer overflow.
(prompt): Use new parameters code, prompt, teles instead of global
variables mode, the_prompt, num_teles.
(num_teles, the_prompt, mode, nbtu, nmin): Remove.
(prompt): Don't write an empty line before argument prompts to auxfp.
(servercmd): Don't strip newline from redirections and execute,
doredir(), dopipe() and doexecute() need it now.
(doredir, dopipe, doexecute): Use new seen_input() instead of gettag().
(doexecute): Set input_fd and leave reading the script file to play().
(serverio, termio, sendeof): Replaced by play(), remove.
(LBUF_LEN_MAX, lbuf, lbuf_init, lbuf_len, lbuf_full, lbuf_line)
(lbuf_putc): New.
(RING_SIZE, ring, ring_init, ring_len, ring_space, ring_peek)
(ring_getc, ring_putc, ring_putm, ring_discard, ring_search)
(ring_from_file, ring_to_file): New.
(clear_recent_input, save_input, seen_input): New.
(MAX): New.
(ioqueue, io, ioq_init, ioq_dequeue, ioq_read, ioq_write, ioq_qsize)
(ioq_drain, ioq_gets, ioqtobuf, enqueuecc, dequeuecc): Unused, remove.
(QEMPTY, qelem, insque, remque, initque): Unused, remove.
(tagstruct, taglist, io_init, gettag): Unused, remove.
passwords on the command line. Antisocially zaps the complete command
line, not just the password. Remove, at least for now.
(main): Update accordingly.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
(tcp_listen, player_addrlen): New. IPv4-only code factored out of
player_init().
(player_init): Use them.
(player_accept): Address family independence.
(tcp_connect): New.
(main): Use it.
(hostaddr, hostconnect, hostport): Internal linkage.
handle.c
(interrupt): Internal linkage.
(interrupt): Use proper type for access from signal handler.
(intr): Don't increment to set, it's unobvious and it could overflow.
manually stripped off padding, which is evil. The new code does
nothing when the stdout is not connected to a terminal.
(SO, smso, SE, rmso): Rename, static linkage.
(putso, putse): New.
(screen): Use it.
(login): New parameter utf8. If set, request option utf-8 from
server.
(expect, recvline): Split recvline() out of expect(). Replace or
remove some unhelpful diagnostics.
(eight_bit_clean): New.
(screen): If eight_bit_clean is set, highlighting is switched with
SO/SI. Else characters with MSB set are highlighted.
(main): New option -u to request UTF-8 and set eight_bit_clean.
linkage that is not in any other header in misc.h. Remove some
redundant declarations elsewhere.
(prompt, doredir, dopipe, doexecute, output, screen, parsedelay):
Static linkage.
