scm_delq_spine_x, really_install_handler, install_handler): New
scheme for triggering signal handlers, to simplify take_signal.
(take_signal): Simplified, to avoid race conditions.
(scm_sigaction_for_thread): Use new Scheme. Validate that thread
hasn't exited yet.
scm_i_thread_root when USE_THREADS is defined. Use scm_root
otherwise.
* scmsigs.c (take_signal): Only call scm_i_thread_root when
USE_THREADS is defined. Use scm_root otherwise.
(scm_sigaction_for_thread): Ignore THREAD argument when
USE_THREADS is not defined. Also, move THREAD argument defaulting
out of HAVE_SIGACTION section, which was a bug.
cell to SCM_BOOL_F, not SCM_EOL.
(scm_i_queue_async_cell): Queue the cell at the end of the list,
and only if the handler procedure is not already present.
(scm_system_async_mark_for_thread): Initialize cdr of handler cell
with SCM_BOOL_F.
* scmsigs.c (scm_sigaction_for_thread): Likewise.
* scmsigs.c (got_signal): Removed.
(signal_handler_cells, signal_handler_threads): New.
(take_signal): Queue the cell of the signal for the specified
thread. Reset the signal handler on systems that don't have
sigaction.
(sys_deliver_signals): Removed.
(close_1): New.
(scm_sigaction_for_thread): Renamed from scm_sigaction and
extended to also set the thread of a signal and allocate a cell
for it. Keep the Scheme name "sigaction". Check that signum is
within range. Also, use SCM_VECTOR_REF instead of SCM_VELTS.
(scm_sigaction): Implement in terms of scm_sigaction_for_thread.
(scm_init_scmsigs): Allocate signal_handler_cells and
signal_handler_threads vectors.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.
* configure.in (guile_cv_have_uint32_t): Look also in
`stdint.h' for uint32_t.
2002-01-28 Stefan Jahn <stefan@lkcc.org>
* symbols.c (scm_c_symbol2str): New function, replacement for
`gh_scm2newsymbol()'.
* strings.c (scm_c_substring2str): New function. Proper
replacement for `gh_get_substr()'.
* socket.c: Include `stdint.h' if available for the `uint32_t'
declaration.
* scmsigs.c (s_scm_sigaction): Initialize `chandler' (inhibits
compiler warning).
* backtrace.c: Include `lang.h' for GUILE_DEBUG conditional.
scm_c_define_gsubr_with_generic): New functions. They replace
scm_make_gsubr and scm_make_gsubr_with_generic. The `make' variants
only create the gsubr object, while the `define' variants also put it
into the current module. Changed all callers. (scm_make_gsubr,
scm_make_gsubr_with_generic): Deprecated.
(scm_c_make_subr, scm_c_define_subr, scm_c_make_subr_with_generic,
scm_c_define_subr_with_generic): New functions. They replace
scm_make_subr, scm_make_subr_opt and scm_make_subr_with_generic. The
`make' variants only create the subr object, while the `define'
variants also put it into the current module. Changed all callers.
(scm_make_subr, scm_make_subr_opt, scm_make_subr_with_generic):
Deprecated.
symbols.c (scm_symbol_to_string), vports.c (scm_make_soft_port):
Change R4RS references to R5RS.
* guile-snarf.awk.in: Fixes so that (i) blank lines in the
docstring source are correctly reproduced in the output (ii)
we don't anymore get occasional trailing quotes. Also reorganized
and commented the code a little.
* scmsigs.c (scm_raise), throw.c (scm_throw): Docstring format
fixes.
* new-docstrings.texi, posix.texi, scheme-control.texi,
scheme-data.texi, scheme-debug.texi, scheme-evaluation.texi,
scheme-io.texi, scheme-memory.texi, scheme-procedures.texi:
Automatic docstring updates (mostly argument name updates and
blank lines).
* scheme-modules.texi: Change double hyphens to single.
* scheme-control.texi (Lazy Catch): Completed.
* posix.texi (Network Databases and Address Conversion): New
subsubsection `IPv6 Address Conversion'.
* error.c, net_db.c, putenv.c, stime.c: Removed declaration of
errno variable (can be a macro on some systems, for example when
using linux libc with threads).
* error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,
posix.c, print.c, putenv.c, scmsigs.c, script.c, simpos.c, smob.c,
socket.c, srcprop.c, stime.c, strop.c, unif.c, vports.c: Added
#include <errno.h> in these 20 out of 100 files.
write it to the temp file first and check the CPP return code.
(I introduced this bug earlier, and this probably caused people
with non-GNU C preprocessors to get empty *.x files and not to
have the build fail right away...).
* scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
-- at least my libc5-based Linux system doesn't define SIGSYS.
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.)
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).
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
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.
