* libguile/fports.c: Reorder includes to put system includes first;
fixes windows/winsock2 include error problem. Rely on Gnulib's
select module.
(fport_input_waiting): Use select instead of scm_std_select.
* libguile/socket.c (scm_init_socket): Remove mingw-specific code.
* libguile/fports.c: Remove ftruncate redefine; mingw is fine.
(scm_i_fdes_to_port): If we have no F_GETFL, just do an fstat. The
right place for an F_GETFL replacement would be in gnulib.
(fport_input_waiting): Remove an outdated comment.
* libguile/error.c (SCM_I_STRERROR, SCM_I_ERRNO): Remove, replacing uses
with strerror and errno.
* libguile/win32-socket.c:
* libguile/win32-socket.h: Remove. Mingw has suitable replacements.
* configure.ac:
* libguile/Makefile.am (EXTRA_libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(noinst_HEADERS): Update for win32-socket removal.
* libguile/ports.h:
* libguile/ports.c (scm_consume_byte_order_mark): New procedure.
* libguile/fports.c (scm_open_file): Call consume-byte-order-mark if we
are opening a file in "r" mode.
* libguile/read.c (scm_i_scan_for_encoding): Don't do anything about
byte-order marks.
* libguile/load.c (scm_primitive_load): Add a note about the duplicate
encoding scan.
* test-suite/tests/filesys.test: Add tests for UTF-8, UTF-16BE, and
UTF-16LE BOM handling.
* libguile/fports.c (scm_setvbuf): Use `scm_take_from_input_buffers'
directly instead of `scm_drain_input'; use `scm_unget_byte' instead of
`scm_unread_string' to put the drained input back to PORT. This
leaves PORT's line/column numbers unchanged, whereas they'd previously
be decreased by the `scm_unread_string' call.
* libguile/ports.c (scm_take_from_input_buffers): Update description and
variable names to refer to "bytes", not "chars".
* test-suite/tests/ports.test ("setvbuf"): New test prefix.
* libguile/ports.c (scm_drain_input): Slight optimization.
* libguile/fports.c (scm_setvbuf): If there is buffered output, flush
it. If there is input, drain it, and then unread it after updating
the buffers. Much more sensible than dropping it silently...
The open-file port should use the 8-bit ISO-8859-1 encoding when
a file is opened using mode "b". Also, it should honor a "coding:"
declaration at the top of a file when reading files where it is present.
* libguile/fports.c (scm_open_file): modified
* test-suite/tests/ports.test: more tests for open-file
* doc/ref/api-io.texi (File Ports): more documentation for open-file
* libguile/filesys.h:
* libguile/filesys.c (scm_i_relativize_path): New function, moved here
from fports.c. Internal for now; we can make it external though if
people like its interface.
* libguile/fports.c (fport_canonicalize_filename): Move all of the
tricky bits to filesys.c. Also fixes a bug in which a delimiter wasn't
stripped.
* libguile/fports.c (%file-port-name-canonicalization): New global var.
(fport_canonicalize_filename): New helper. If
%file-port-name-canonicalization is 'absolute, then run file port
names through canonicalize_path; if it's 'relative, then canonicalize
the name, but strip off load paths; otherwise leave the port name
alone.
(scm_open_file): Use fport_canonicalize_filename.
(scm_init_fports): Define %file-port-name-canonicalization.
The intent is to allow compilation with `-Wundef', which in turn should
make it easier to catch erroneous uses of nonexistent macros.
* libguile/__scm.h: Don't assume `BUILDING_LIBGUILE' is defined.
* libguile/conv-uinteger.i.c (SCM_TO_TYPE_PROTO): Remove unneeded CPP
conditional on `TYPE_MIN == 0'.
* libguile/fports.c: Check for the definition of `HAVE_CHSIZE' and
`HAVE_FTRUNCATE', not for their value.
* libguile/ports.c: Likewise.
* libguile/numbers.c (guile_ieee_init): Likewise with `HAVE_DINFINITY'
and `HAVE_DQNAN'.
* test-suite/standalone/test-conversion.c (ieee_init): Likewise.
* libguile/strings.c: Likewise with `SCM_STRING_LENGTH_HISTOGRAM'.
* libguile/strings.h: Likewise.
* libguile/tags.h: Likewise with `HAVE_INTTYPES_H' and `HAVE_STDINT_H'.
* libguile/threads.c: Likewise with `HAVE_PTHREAD_GET_STACKADDR_NP'.
* libguile/vm-engine.c (VM_NAME): Likewise with `VM_CHECK_IP'.
* libguile/gen-scmconfig.c (main): Use "#ifdef HAVE_", not "#if HAVE_".
* libguile/socket.c (scm_setsockopt): Likewise.
Ports are given two additional properties: a character encoding and
a conversion failure strategy. These properties have getters and setters.
The new properties are used to convert any locale text to/from the
internal representation of strings.
If unspecified, ports use a default value. The default value of these
properties is held in a fluid. The default character encoding can be
modified by calling setlocale.
ISO-8859-1 is treated specially. Since it is a native encoding of
strings, it can be processed more quickly. Source code is assumed to be
ISO-8859-1 unless otherwise specified. The encoding of a source code
file can be given as 'coding: XXXXX' in a magic comment at the top of a
file.
The C functions that deal with encoding often use a null pointer
as shorthand for the native Latin-1 encoding, for efficiency's sake.
