+2004-04-06 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * inline.h (scm_cell): use SCM_GC_CELL_WORD for checking tag.
+
+ * chars.h (scm_init_chars): change scm_{upcase,downcase} to
+ scm_c_{up,down}case.
+ (SCM_MAKE_CHAR): add (unsigned char) cast. This prevents havoc
+ when hi-bit ASCII is subjected to SCM_MAKE_CHAR().
+
+2004-04-06 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_ash): Remove stray "}" in docstring.
+
+ * numbers.c (scm_make_ratio): For inum/bignum integer detection, use
+ x==SCM_MOST_NEGATIVE_FIXNUM explicitly, for clarity and to avoid
+ calling mpz_cmp_ui in most cases.
+
+ * numbers.c (scm_quotient, scm_remainder): In inum/big, use mpz_cmp_ui
+ for big == abs(most-negative-fixnum) special case.
+ (abs_most_negative_fixnum): Remove, no longer used.
+
+ * scmsigs.c (scm_sigaction_for_thread): Correction to signum range
+ test, avoids SCM_VECTOR_REF outside bounds of signal_handlers on
+ calling (sigaction NSIG).
+
+ * simpos.c (scm_system_star): Fix execargv memory leak, merge parent
+ and fork error cases to do this.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (CEVAL): Don't distinguish between short and long
+ instructions when dispatching - just always dispatch on the
+ instruction code, which is common for short and long instructions.
+ Further, removed unnecessary goto statements and added comment.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_unmemocopy): Don't distinguish between short and
+ long instructions when dispatching - just always dispatch on the
+ instruction code, which is common for short and long instructions.
+ Further, removed unnecessary goto statements, fixed indentation
+ and replaced SCM_IMP predicates by SCM_NULLP.
+
+2004-04-03 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (scm_lookupcar1, CEVAL): Use SCM_ILOCP instead of
+ comparison with SCM_ILOC00. In CEVAL, eliminate goto-label
+ 'checkmacro'.
+
+2004-03-31 Kevin Ryde <user42@zip.com.au>
+
+ * simpos.c: Include <signal.h> for SIG_IGN and friends.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ Introduce scm_debug_mode_p as a replacement for scm_debug_mode and
+ SCM_DEBUGGINGP:
+
+ * debug.h (scm_debug_mode_p, scm_debug_mode, SCM_DEBUGGINGP),
+ eval.c (scm_debug_mode_p): Deprecated scm_debug_mode and
+ SCM_DEBUGGINGP. Provided scm_debug_mode_p instead, to have one
+ single interface that also matches the naming conventions.
+ Probably scm_debug_mode_p should be part of the private interface
+ anyway.
+
+ * debug.h (scm_debug_mode_p), backtrace.c (display_error_body),
+ eval.c (SCM_APPLY, scm_trampoline_0, scm_trampoline_1,
+ scm_trampoline_2): Change uses of scm_debug_mode or SCM_DEBUGGINGP
+ to scm_debug_mode_p.
+
+
+ Deprecate direct access to scm_ceval, scm_deval and scm_ceval_ptr:
+
+ * eval.h (scm_ceval, scm_deval, scm_ceval_ptr), debug.h
+ (scm_ceval_ptr): Deprecated. Moved declaration of scm_ceval_ptr
+ from debug.h to eval.h.
+
+ * debug.h (SCM_RESET_DEBUG_MODE): Don't access scm_ceval_ptr any
+ more, just leave it with setting scm_debug_mode_p, which is
+ equivalent for practical purposes.
+
+ * deprecated.h (SCM_XEVAL, SCM_XEVALCAR): Call scm_i_eval_x
+ instead of *scm_ceval_ptr. Leave all evaluating to scm_i_eval_x.
+
+ * gdbint.c (gdb_eval): Call scm_i_eval_x instead of scm_ceval.
+
+ * eval.c (ceval, deval, scm_ceval, scm_deval): Made scm_ceval
+ static and renamed it to ceval throughout. Provide a new exported
+ but deprecated function scm_ceval as a wrapper for backwards
+ compatibility. The same is done for the deval/scm_deval pair of
+ functions.
+
+ * eval.c (CEVAL, SCM_CEVAL): Renamed SCM_CEVAL to CEVAL
+ throughout. Defined CEVAL to ceval or deval, based on compilation
+ phase.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR): Dispatch on scm_debug_mode_p
+ to ceval and deval instead of calling *scm_ceval_ptr.
+
+ * eval.c (dispatching_eval): New deprecated static function.
+
+ * eval.c (scm_ceval_ptr): Initialized to dispatching_eval in order
+ to emulate its old behaviour as closely as possible.
+
+
+ Change the evaluator such that only expressions for which pair? is
+ true are passed to CEVAL, and such that all other expressions are
+ evaluated outside of CEVAL:
+
+ * eval.c (EVAL): New, provided in analogy to EVALCAR. Evaluate an
+ expression that is assumed to be memoized already. All but
+ expressions of the form '(<form> <form> ...)' are evaluated inline
+ without calling an evaluator.
+
+ * eval.c (SCM_XEVAL, SCM_XEVALCAR, EVALCAR): Evaluate all but
+ expressions of the form '(<form> <form> ...)' inline without
+ calling an evaluator.
+
+ * eval.c (scm_i_eval_x, scm_i_eval, scm_ceval, scm_deval): Handle
+ the special case of unmemoized symbols passed on the top level.
+
+ * eval.c (CEVAL): Change calls to CEVAL to EVAL, except where it
+ is known that the expression passed to CEVAL is of the form
+ '(<form> <form> ...)'. Remove handling of the tc7-objects, since
+ now it is known that the input expression of CEVAL is a pair.
+
+2004-03-29 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c (is_self_quoting_p): New static function.
+
+ (scm_m_quote): Use is_self_quoting_p.
+
+ (copy_tree): Corrected typo in comment.

+
+ * eval.c (s_scm_copy_tree): idem.
+
+ * list.c (s_scm_filter): remove "pointer" from doc string.
+
+ * gc.h (SCM_GC_CELL_TYPE): SCM_GC_CELL_TYPE uses SCM_GC_CELL_OBJECT.
+
+ * goops.h (SCM_NUMBER_OF_SLOTS): don't SCM_UNPACK the result.
+
+ * backtrace.c ("display_backtrace_body"): SCM_PACK before SCM_EQ_P
+ (display_frame): idem.
+ (display_backtrace_file_and_line): idem.
+
+ * tags.h (SCM_UNPACK): stricter typechecking on SCM_UNPACK
+ arguments.
+
+2004-03-26 Kevin Ryde <user42@zip.com.au>
+
+ * filesys.c (scm_getcwd, scm_readlink): Avoid memory leak on errors.
+
+ * numbers.c (scm_modulo): For inum/big and big/big, remove test of
+ big==0 since that never occurs.
+
+ * numbers.c, numbers.h (scm_modulo_expt): Renamed from
+ scm_modular_expt, matching scheme level name `modulo-expt'.
+
+ * numbers.c (scm_modular_expt): Return a negative remainder for a
+ negative divisor, the same as `modulo' does.
+
+2004-03-26 Eric Hanchrow <offby1@blarg.net>
+
+ * numbers.c, numbers.h (scm_modular_expt): New function.
+
+2004-03-25 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_min, scm_max): Correction to big/real and real/big,
+ return inexact as required by r5rs.
+
+2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * eval.c: Separated some definitions relevant for execution from
+ the memoization part of the file.
+
+ (copy_tree): New static function
+
+ (scm_copy_tree): Rewritten to fix two kinds or bugs: First, cyclic
+ structures are detected now and will lead to an exception instead
+ of forcing guile to run in an endless loop, using up all the
+ system's memory. Second, arrays in the cdr of an improper list
+ are now copied. See the new test cases in eval.test.
+
+2004-03-24 Dirk Herrmann <dirk@dirk-herrmanns-seiten.de>
+
+ * posix.c (scm_gethostname): Make sure len is initialised before
+ it is used. Restructured to (hopefully) represent possible
+ configurations more clearly in the code. Added unwind handler.
+
+2004-03-23 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_gethostname): Use sysconf(_SC_HOST_NAME_MAX) and/or
+ MAXHOSTNAMELEN when available.
+
+2004-03-21 Marius Vollmer <mvo@zagadka.de>
+
+ * read.c (skip_scsh_block_comment): Also recognize '\r' as a line
+ terminator. Rewritten the logic as a state machine, I must have
+ been doing too much VHDL lately...
+
+ * eval.c (scm_ceval, scm_deval): Explicitely evaluate ports to
+ themselves. Thanks to Han-Wen Nienhuys!
+
+ * list.c: Changed docstrings so that they no longer talk about
+ returning 'pointers' to something.
+
+2004-03-20 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc.c: remove set_debug_cell_accesses! when
+ SCM_DEBUG_CELL_ACCESSES is not defined. Scheme source code should
+ use (if (defined? 'set-debug-cell-accesses!) .. ) to switch on
+ debugging conditionally.
+
+2004-03-21 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c (scm_gmtime): Use gmtime_r when available, for thread safety.
+
+2004-03-20 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_gethostname): Preserve errno across free() call.
+
+2004-03-18 Han-Wen Nienhuys <hanwen@xs4all.nl>
+
+ * gc-card.c (sweep_card): use SCM_GC_SET_CELL_WORD for setting
+ free cells.
+
+2004-03-14 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.
+ (strptime): Use HAVE_DECL_STRPTIME for when to give own prototype.
+
+2004-03-07 Kevin Ryde <user42@zip.com.au>
+
+ * stime.c (scm_gmtime): Return bd_time->tm_zone when available, rather
+ than "GMT" always.
+ (filltime): Make zname parameter "const".
+
+2004-03-03 Mikael Djurfeldt <mdj@chunk.mit.edu>
+
+ * threads.c, threads.h (scm_c_scm2thread): New function.
+
+2004-02-29 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (guile_ieee_init): Use C99 INFINITY and NAN when
+ available. Test HAVE_DINFINITY and HAVE_DQNAN for those globals, in
+ particular don't assume "defined (__alpha__) && ! defined (linux)"
+ means OSF. Remove "SCO" code, which was not really SCO specific and
+ which John W. Eaton advises should be long past being needed.
+
+ * posix.c (scm_execl, scm_execlp, scm_execle): Avoid memory leak under
+ error throw.
+
+2004-02-24 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_cuserid): Use a private result buffer, for thread safe.
+
+2004-02-22 Kevin Ryde <user42@zip.com.au>
+
+ * numbers.c (scm_max, scm_min): For one arg, dispatch to generic for
+ complex, same as for two args. (Handle only inum, big, real, frac).
+
+2004-02-21 Kevin Ryde <user42@zip.com.au>
+
+ * posix.c (scm_crypt): Use new HAVE_CRYPT.
+ (<crypt.h>): Remove HAVE_LIBCRYPT condition.
+ Reported by Andreas Voegele.

2004-02-20 Neil Jerram <neil@ossau.uklinux.net>
* list.c (scm_list_n): Add #if SCM_DEBUG_CELL_ACCESSES_P around
