scm_must variants of malloc/free etc., should be used, based on
explanation from Dirk Herrmann.
* fports.c (scm_fport_buffer_add): use FUNC_NAME instead of a local
string with procedure name. use scm_must_malloc instead of malloc.
(scm_setvbuf, scm_fdes_to_port, fport_close): use scm_must variants
of malloc/free.
* ports.c (scm_add_to_port_table, scm_remove_from_port_table,
scm_ungetc): use scm_must variants of malloc/realloc/free.
(scm_add_to_port_table, scm_ungetc): define FUNC_NAME.
read-string!/partial.
* ports.c (scm_take_from_input_buffers): new procedure used by
scm_read_string_x_partial.
(scm_drain_input): use scm_take_from_input_buffers.
(fport_flush, fport_close): silently ignore I/O errors when
closing a port during gc. it's better than aborting in scm_error.
* throw.c (scm_handle_by_message): remove obsolete comment.
* Fix some string/symbol output problems with regards to substrings.
* Fix error output to prefer procedure name parameters over stack data.
* Use SCM_(SET_)?FILENAME where appropriate.
* Prefer calling scm_remember over scm_protect/unprotect_object calls.
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
(end_input_void_port): renamed to end_input_default.
* init.c (scm_standard_stream_to_port): create a void port instead
of opening /dev/null if the standard file descriptors are bad.
advantages: no portability problems, doesn't waste a file descriptor,
simplifies the code (thanks to Marius for the idea).
* vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
* void ports: make reading from a void port give EOF instead of
segv:
* ports.c (s_scm_sys_make_void_port): modified docstring.
(fill_input_void_port): new proc.
(scm_init_ports): set up fill_input_void_port.
* ports.c (scm_port_non_buffer): new proc.
(scm_void_port): call scm_port_non_buffer.
* fports.c (scm_setvbuf): docstring: remove the fcntl documentation
which was incorrectly appended.
the fdes is valid before doing anything else. check that
the file descriptor supports the modes required.
(scm_fport_buffer_add): don't throw an error if fstat doesn't
work: just use the default buffer size.
* throw.c: change an outdated comment about scm_internal_catch
BODY: it doesn't take a jumpbuf arg.
* init.c (scm_standard_stream_to_port): install a handler in case
scm_fdes_to_port throws an error. don't check here whether the
file descriptor is valid, since scm_fdes_to_port will do that.
set the revealed count depending on whether the port got the
standard file descriptor.
(stream_body_data): new type.
(stream_body, stream_handler): new procs.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
where possible.
* symbols.c (scm_sysintern0): Fixed the function name in a
scm_misc_error invocation.
* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
use scm_return_first to ward off latent GC bug that Mikael caught.
* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
used before but should've been.
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
GUILE_PROC1. Build guile-procedures.txt, and add that file to
pkgdata_DATA.
* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.
* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".
* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented. Also, all
the markup is currently still texinfo. I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
prototypes.
* eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
char *. ANSI prototypes caught this.
* strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
that I missed.
* scm_validate.h: Use SCM_BOOLP for validating bools. Do not
expand macros if SCM_DOCSTRING_SNARF.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
caller of the ptob seek procedure to the implementation. This
gives more control in general to the ptob seek: in particular the
change of 1999-10-20 can be made to work without breaking seek on
string ports. There's a comment in NEWS about upgrading port
types.
* ports.c (scm_seek): don't reset the port buffers here.
* fports.c (fport_seek): reset the buffers, except for the
0 SEEK_CUR case.
* strports.c (st_end_input): (bug fix): decrement pt->read_pos by
offset. check that it's not less than read_buf.
(st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
case and currently reading.
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).
* strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
* ports.c (scm_add_to_port_table): initialise rw_random to 0.
* ports.h (scm_port): change the comments on rw_random and rw_active.
SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
zero). The debugger knows about enums, but doesn't know about
#defines.
(typedef scm_port): Declare rw_active member to be an enum
scm_port_rw_active.
* fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
instead of zero.
* ports.c (scm_add_to_port_table): Same.
* strports.c (st_flush, st_end_input): Same.
* fports.c (fport_input_waiting): if select is used, return 1
instead of whatever FD_ISSET expands to. maybe it will be useful
to interpret the value from the input_waiting ptob procedure as a
lower bound on the number of bytes available.
* Mikael asked for a few names to be changed...
* 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:
fflush -> flush, read_flush -> end_input, fclose -> close,
fill_buffer -> fill_input, ftruncate -> truncate,
input_waiting_p -> input_waiting.
* ports.c (end_input_void_port): was read_flush_void_port.
(scm_set_port_end_input): was scm_set_port_flush_input.
(scm_set_port_flush): was scm_set_port_write.
(scm_set_port_input_waiting): was scm_set_port_input_waiting_p
(scm_end_input): was scm_read_flush.
(scm_fill_input): was scm_fill_buffer.
(scm_flush): was scm_fflush.
* fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
(fport_end_input): was local_read_flush.
(fport_flush): was local_fflush.
(fport_close): was local_fclose.
(fport_truncate): was local_ftruncate.
(fport_seek): was local_seek.
(fport_free): was local_free.
(fport_fill_input): was fport_fill_buffer.
* strports.c (st_end_input): was st_read_flush.
(st_truncate): was st_ftruncate.
* vports.c: (sf_flush): was sfflush.
(sf_close): was sfclose.
(sf_fill_input): was sf_fill_buffer.
* ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
change callers.
it's more efficient for unbuffered fports (e.g., sockets.)
* ports.c (scm_puts): use ptob->write.
* vports.c (scm_make_sfptob): set write proc in ptob.
* strports.c (scm_make_stptob): set write proc in ptob.
* ports.c (write_void_port): new procedure.
* vports.c (sf_write): new procedure.
* ports.c (scm_lfwrite): use ptob->write.
* strports.c (st_write): new procedure.
* fports.c (fport_write): new procedure.
(scm_make_fptob): set write in ptob to fport_write.
* ports.h: prototype for scm_set_port_write.
* ports.c (scm_make_port_type): initialise ptob write procedure.
(scm_set_port_write): new proc.
