random access. rw_active needs to be maintained even for single
directional ports, otherwise scm_seek and probably other things are
broken. (thanks to Roland Orre).

zero). The debugger knows about enums, but doesn't know about
#defines.

to interpret the value from the input_waiting ptob procedure as a
lower bound on the number of bytes available.

* ports.c (scm_make_port_type): take the write procedure as the
second argument instead of the flush procedure.
* ports.h (scm_ptob_descriptor): rename the ptob procedures:

(scm_set_port_write): new proc.
creation of port types (replaces scm_newptob). Just as for the
smobs, we need to separate the internal representation of smob
types from the interface, so that we easily can add new fields and
rearrange things without caring about backward compatibility.
This change was forced by the need in GOOPS to create classes
representing port types.
(scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

* fports.c (local_read_flush): use offset, don't reset putback
buffer here.
* ports.h (scm_ptobfuns): let read_flush take an offset argument,
which is the number of chars from the putback buffer.
* ports.c (scm_read_flush): new procedure, resets the putback
buffer before calling the ptob routine.
scmsigs.c, strports.c, vports.c: Install the sources which
actually correspond to the changes described below. I got the
ChangeLog entries and the patch from two different places...
newline. A bit faster, and definitely hairier.

Add some simple-minded support for line buffered ports.
* ports.h (SCM_BUFLINE): New flag for ports.

buffering.
(scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
and there's a newline to be written, flush the port.

position.

fports.c: scm_fport_drain_input: removed. do it all in ports.c.
strports.c (scm_mkstrport): check that pos is reasonable.
ioext.c (scm_ftell, scm_fseek): use lseek.

equivalent to fflush for the read buffer.

strport.c (st_read_flush): likewise.
vport.c (sf_read_flush): likewise.
fports.h (struct scm_fport): remove random member. there's nothing

reading and writing members with rw_active member.

signals (it was only being done for handlers installed from Scheme).
Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
waiting for input caused an EINTR error from read.
* ports.h (struct scm_port_table): make all the char members
unsigned, so they convert to int without becoming negative if large.
* fports.c (scm_fdes_wait_for_input): forgot to check compilation

fport_wait_for_input and take a port instead of a fdes.
use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
* readline.c (scm_readline): Applied a patch from Greg Harvey to
get readline support working again: use fdopen to get FILE objects.
* gc.c (scm_init_storage): install an atexit proc to flush the
ports.
(cleanup): the new proc. it sets a global variable which can be
checked by the ptob flush procs to avoid trying to throw
exceptions during exit. not very pleasant but it seems more reliable.
* fports.c (local_fflush): check terminating variable and if set
don't throw exception.
* CHECKME: that the atexit proc is installed if unexec used.
* throw.c (scm_handle_by_message): don't flush all ports here.
it still causes bus errors.

and move to ioext.c.
* fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.

currently use shortbuf.)
* fports.c (scm_standard_stream_to_port): moved to init.c and
made static.
* init.c (scm_init_standard_ports): make stdout and stderr
unbuffered if connected to a terminal. with stdio they
were line-buffered by default.

change flush proc definitions.
* strports.c (scm_call_with_output_string): get size from
buffer instead of port stream.

(st_flush): new proc.
* ports.h (struct scm_port_table): added write_end member,
as an optimisation. set it where write_buf_size is set.
* ports.h (struct scm_port_table): change stream from void *
back to SCM. SCM presumably must be large enough to hold a
pointer (and probably vice versa but who knows.)
(SCM_SSTREAM): deleted. change users back to SCM_STREAM.
(scm_puts): rewritten
* fports.c (local_ffwrite, local_fputs): removed.

replaces reading member in fport struct.
* vports.c (sfgetc): store the getted char into the buffer.
rename to sf_fill_buffer and install it for fill-buffer in ptob.
the Scheme interface is still a procedure that gets a char.
(scm_make_soft_port): set up the port buffer (shortbuf).

* fports.h (SCM_FDES_RANDOM_P): new macro. use it in
scm_fdes_to_port and scm_redirect_port.

local_fputs): Call them.
(local_fflush): Mark the port as ready for reading and writing.
(scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
flags on new port objects. This might not be accurate --- who
knows what state the FILE * is in when we get it --- but it won't
do extraneous calls to fflush or fseek, so it's no worse than the
behavior before this change.
* ports.h: Add comment.
Centralize the creation of port objects based on stdio FILE * in
fports.c; don't just throw them together anywhere.
* fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
what the rest of Guile wants. Don't set the revealed count;
that's only appropriate for stdin, stdout, stderr.

count.
* init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
not scm_stdio_to_port.

* fports.c (scm_open_file): Same.
* posix.c (scm_pipe): Same.
* socket.c (scm_sock_fd_to_port): Same.
* ioext.c (scm_fdopen): Same.
(scm_freopen): Moved from here to...
* fports.c (scm_freopen): ... here. This is really something that
munges the internals of an fport, so it should go here.
* fports.h (scm_stdio_to_port): Adjust prototype.
(scm_standard_stream_to_port, scm_freopen): New protoypes.
* ioext.h (scm_freopen): Prototype removed.
they get passed the port object, not the port's stream.
* ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
* gc.c (scm_gc_sweep): Pass the port itself to the free function.
* genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
Pass the port itself to the scm_ptobs function.
* ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
scm_generic_fgets): Same.
(putc_void_port, puts_void_port, write_void_port, flush_void_port,
getc_void_port, fgets_void_port, close_void_port): Just change the
argument names; these functions don't really do anything.
* fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
port as an argument, and use SCM_STREAM to get the stdio FILE *.
Also, use prototyped definitions, and get rid of the extra
declarations.
(scm_fptob, scm_pipob): We don't need casts here any more.
* strports.c (prinstpt): Use prototype declarations.
(stputc, stwrite, stputs, stgetc): Take the port as an argument,

definitions, and get rid of the extra declarations.
* vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
noop0): Same.
* ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
prototype; it's okay (preferred, even!) to use ANSI C in Guile.
* ports.c: Doc fixes.
(scm_fflush): Moved to ...
* genio.c (scm_fflush): ... here, amongst all the other port
method invocation functions.
* genio.h, ports.h: The prototype moves too.
ioext.c (%read-line): Return a cons of the input line and its terminator.
fports.c, genio.c, genio.h, ports.c, ports.h: Change fgets methods
to return the string length as well as its contents.
* fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
and scm_must_free, since ultimately the string returned will be copied
by scm_makfrom0str anyway. Also, read any characters that may have
been pushed onto the port with scm_ungetc.
* ports.c (scm_generic_fgets): Same as for scm_fgets.
* ioext.c (scm_read_line): Free string after Guilifying it.
* ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
* ports.h: prototypes too.
* ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
* fports.h: prototype too.
* fports.c (scm_evict_ports): moved from ioext.c.
* ports.c (scm_close_port): return a boolean instead of unspecified.
throw an error if an error other than EBADF occurs.
* filesys.h: scm_close prototype.
* filesys.c (scm_close): new procedure, can close file descriptors
and ports (scsh compatible).
* ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
optional argument.
srcprop.h, tags.h, throw.c, unif.c: Added new selectors
SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
Motivation: Safer use. Some other macros are defined in terms of
these operations. If these are defined using the SCM_SETCXR
(<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
to inefficiency and an <e1> with side-effects could potentially
break. Also, these particular operations are heavily utilized in
the garbage collector. In unoptimized code there will be a
measurable speedup.

vports.c: Cleaned up use of pairs: Don't make any special
assumptions about the internal structure of selectors and
mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
declare the char * to be const. Avoids a warning in rgx.c.
* ports.h: spelling fix.
* filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
error messages.
* load.c (scm_sys_try_load_path): throw an error if file not found
(like it says it in NEWS).
scm_port_\1; Added mutator scm_set_port_filename_x (used when
loading source from non-file ports, which, e. g., happens when
using the Emacs interface).
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.
