an unknown format directive character; emit
an error that the character is missing.

Retracting the recent change to add the "t" mode when
opening non-binary streams on Cygwin, which arranges
for line ending conversion. This restores the Unix-like
treatment of text files on Cygwin, which is expected
of programs.
The Windows native version of TXR will do line ending
conversion thanks to the behavior of text streams in the
Cygnal fork of Cygwin.
* stream.c (format_mode): Only add the "t" option
on Cygwin if compatibility with 144 and 145 is selected.
* txr.1: Updated compatibility notes.

* stream.c (shell, shell_arg): New variables.
(sh): Use shell and shell_arg, rather than hard-coded
"/bin/sh" and "-c".
(stream_init): Initialize shell and shell_arg to
POSIX values. On Cygwin, call getusershell, and if it
reports cmd.exe, use that instead, and adjust shell_arg
to "/c". This will happen if the Cygwin DLL being used
is the Cygnal version.

mode by default, such that "\r\n" is converted to "\n".
Cygwin's stdio streams aren't doing this. This is fine when
working in the Cygwin world, but not fine when we are making a
"native" Windows program with the help of the Cygwin DLL.
However, Cygwin supports the "t" mode letter in fopen, and
that forces a text mode which does the conversion.
* stream.c (format_mode): On Cygwin, if the mode isn't
binary, add the 't' letter to the normalized mode
string, unless compatibility <= 143 is requested.
* txr.1: Added compat notes.

don't bother doing anything.

the :byte-oriented property is inquired.
(stdio_set_prop): Map :byte-oriented to the is_byte_oriented
flag.
(stdio_get_char): Do not decode UTF-8 if is_byte_oriented is
set; just read one character.
(make_stdio_stream_common): Initialize is_byte_oriented to 0.

Let's use our usleep_wrap function which uses nanosleep.
The old sleep can interact with SIGALRM.
* stream.c (tail_calc): Calculate microseconds instead
of seconds.
(sleep): Wrapper for Windows gone.

throw-on-error-p parameter.

* stream.c (record_adapter): Use default_bool_arg
rather than tnil. Since rb->include_match ends up passed
directly to read_until_match, which deals with argument
defaulting, we could just store the argument value into the
structure.

When subprocesses are created using open-command,
open-process, run or sh, any streams not bound by
those functions are obtained from *stdin*, *stdout*
or *stderr*, as appropriate. Thus manipulating these
variables has the effect of redirecting not only
local output within the program but over coprocesses
as well.
* stream.c (struct save_fds): New type.
(FDS_IN, FDS_OUT, FDS_ERR): New macros.
(fds_init, fds_subst, fds_swizzle, fds_restore): New static
functions.

* glob.c (glob_wrap): Perform argument conversions
that might throw before allocating UTF-8 string.
* parser.y (text): In the action for SPACE, the lexeme
is not needed so free($1) right away. 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,

are not shared with anything. Adding additional logic
to completely recycle the stack.

get the character from the push-back list.

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.

position into the stream, rather than the original
value, which does nothing.

* lisplib.c (sock_set_entries): Add auto-load entry

* stream.c (do_parse_mode): New static function.
(parse_mode): Logic moved into do_parse_mode, leaving this
function as a wrapper for do_parse_mode. Check added
for malformed mode, so functions which call parse_mode
now have the check. Added defaulting for mode_str
argument, inside do_parse_mode.
(normalize_mode): Call do_parse_mode instead of parse_mode.
Don't default mode_str argument, since do_parse_mode
does that.

The main aim here is to pave the way for conversion between
arbitrary buffers of bytes (that may include embedded NUL
characters) and a wide string.
Also, a potential security hole is closed. When we convert a
TXR string to UTF-8 for use with some C library API, any
embedded pnul characters (U+DC00) turn into NUL
bytes which effectively cut the UTF-8 string short, and
silently so. The C library function receives a shortened
string. This could be exploitable in some situations.
* lib.c (int_str): Use utf8_dup_to_buf instead of
utf8_dup_to_uc. Pass 1 to have the buffer null-terminated,
since mp_read_radix depends on it.
* stream.c (make_string_byte_input_stream): Use
utf8_dup_to_buf. This gives us the size, soo we don't have to
call strlen. The buffer is no longer null terminated, but the
byte input stream implementation never relied on this.
* utf8.c (utf8_from_buf): Replacement fors utf8_from_uc
which doesn't assume that the buffer of bytes is
null-terminated. It can produce a wide string containing
U+DC00 characters corresponding to embedded nulls in the
original buffer.
(utf8_from): Calculate length of null-terminated string and use
utf8_from_buf.
(utf8_to_buf): Replacement for utf8_to_uc. Can produce
a buffer which is or is not null-terminated, based on new
argument.
(utf8_to): Use utf8_to_buf, and ask it to null-terminate,
thus preserving behavior.
(utf8_dup_from_uc): This function was not used anywhere
and is removed.
(utf8_dup_to_buf): Replacement for utf8_dup_to_uc which
takes an extra agrgument, whether to null-terminate
or not.
(utf8_dup_to): Apply security check here: is the resulting
string as long as utf8_to says it should be? If not,
it contains embedded nulls. Throw an exception.
* utf.h (utf8_from_uc, utf8_to_uc, utf8_dup_from_uc,
utf8_dup_to_uc): Declarations removed.
(utf8_from_buf, utf8_to_buf, utf8_dup_to_buf): Declared.

* stream.c (tail_strategy): Apply the mode whenever a new
stream is opened.

we can apply all the same attributes to a newly opened
stream that we applied to the original stream.

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.

* 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.

* stream.c (parse_mode): Recognize "l" and "u", and

(set_mode_props): More complicated behavior to
integrate the new options with the line mode defaulting
behavior of "i".
* stream.h (struct stdio_mode): New members unbuf
and linebuf. All members become bit fields of width 1.
(stdio_mode_init_trivial): Initializers for new members.
* txr.1: Documented.

* socket.c (open_sockfd): We no longer need to set
stream sockets to line buffered mode here;
it's done in set_mode_props.
* stream.c (set_mode_props): If the mode specifies interactive,
streams open for writing are also switched to line buffering.
* txr.1: Documented under open-file, and open-socket.

This fix is required for the stream socket test case to pass.
Some interaction between a stdio stream in line buffering
mode and the putc function causes a stream to lose data.
If we use fputs instead to output a character, the
issue goes away.
* stream.c (se_putc): When compiling for Cygwin, construct
a one-character-long string and use fputs, rather than putc.

(stdio_stream_print): Obtain descr by calling get_prop
method rather than directly from h->descr, in case it is
dynamically computed. Use ~a rather than ~s for incorporating
string properties into printed form, to eliminate quotes.
(stdio_stream_mark): Mark new addr member.
(sock_get_prop, sock_set_prop): New static functions.
(stdio_set_sock_peer): Invalidate h->descr by setting
it to nil.
(make_stdio_stream_common): Initialize h->addr to nil.
(make_sock_stream): Specify description as nil rather
than "socket".
(stream_init): Intern the addr keyword, and initialize
the addr_k variable.
Set the name of stdio_sock_ops to "stream-sock"
rather than leaving it inherited as "file-stream".
Wire in the sock_get_prop and sock_set_prop functions into
stdio_sock_ops.
* stream.h (addr_k): Declared.

* socket.c (dgram_set_sock_peer): Assign to struct
dgram_stream using using set macro.
* stream.c (stdio_set_sock_peer): Assign to struct
stdio_handle peer using set macro.

|
|
|
| |
* 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").

* socket.c (struct dgram_stream): New struct.
(make_dgram_sock_stream, dgram_print, dgram_mark,
dgram_destroy, dgram_overflow, dgram_put_byte_callback,
dgram_put_string, dgram_put_char, dgram_put_byte,

dgram_get_sock_type, dgram_get_sock_peer,
dgram_set_sock_peer, dgram_get_error, dgram_get_error_str,
dgram_clear_error): New static functions.
(dgram_strm_ops): New static structure.
(sock_listen): Check against datagram sockets which have
a peer; otherwise a no-op for datagram sockets.
(sock_accept): Special logic for dgram sockets.
(open_sockfd): Function moved here from stream.c, and
augmented to open dgram stream for dgram sockets.
(open_socket): Function moved here from stream.c.
(sock_load_init): Fill in some operations in dgram_strm_ops.
* stream.c (generic_get_line, make_sock_stream,
errno_to_string): Statics become external.
(open_sockfd, open_socket): Functions removed from here,
moved to socket.c.
* stream.h (generic_get_line, make_sock_stream,
errno_to_string): Declared.

|
|
|
| |
* stream.c (get_string): Use default_arg_strict instead
of default_arg, so that the t value is only substituted for a
missing argument, not for a nil argument.
|
|
|
|
|
|
| |
* stream.c (stdio_unget_char): Remove not-a-character check
from character argument.
(unget_char): Perform check here, thus for all stream types.

(fill_stream_ops): Set up get_fd function pointer in
strm_ops.
(null_ops): Add null_get_fd.
(stdio_get_fd): New static function.
(stdio_ops, tail_ops, pipe_ops): Specify stdio_get_fd as get_fd
function.
(stream_fd): Rewritten as call to get_fd operation.
(dir_ops, string_in_ops, byte_in_ops, string_out_ops,
strlist_out_ops, cat_stream_ops): Specify null as get_fd
function, to be defaulted by fill_stream_ops.
(delegate_get_fd): New static function.
(record_adapter_ops): Specify delegate_get_fd as get_fd
function.
(stream_init): Change fileno intrinsic registration to point
to stream_fd function.
