+
+1998-08-11 Radey Shouman <radey@colorage.com>

+ LETREC, since internal DEFINE is now rewritten.
+
+1998-08-10 Aubrey Jaffer <jaffer@colorage.com>
+
+ * sys.c (scm_fill_freelist): added. Assures that at least
+ MIN_GC_YIELD cells are in freelis. This is used before returning
+ from interrupts.
+
+ * repl.c (handle_it): Discard 2 cells (because of CDR in NEWCELL).
+ Call scm_fill_freelist();
+
+1998-08-08 Aubrey Jaffer <jaffer@ai.mit.edu>

+
+1998-07-27 Radey Shouman <radey@colorage.com>
+
+ * sys.c (scm_estk_grow): Protected critical section with
+ DEFER/ALLOW_INTS
+
+ (must_malloc): (must_realloc): Protected igc call with
+ DEFER/ALLOW_INTS.
+
+ (scm_egc): Added DEFER/ALLOW_INTS around call to igc -- prevents
+ interrupts violation message in debug mode.
+
+ (igc): Now SCM_ENV_SAVE before any gc marking to fix gc bug
+ tickled by running Scheme code from interrupts.
+
+ (scm_egc): (scm_egc_copy_roots): Now take a single argument, a gc
+ root. Simplifies handling of the case where scm_egc calls igc,
+ and possibly itself.
+
+ * repl.c (growth_mon): Now prints "shrank" instead of "grew" if
+ the relevant limit decreased.
+ (handle_it): Do env cache gc before applying interrupt
+ handler, to protect data on the estk, which might move.
+
+Wed Jul 22 16:36:48 EDT 1998 Aubrey Jaffer <jaffer@scm.colorage.net>
+
+ * patchlvl.h (SCMVERSION): Bumped from 5c1 to 5c2.

+
+ * sys.c: Added include of unistd.h for linux.
+ (freeprint): Distinguishes between free cells (on freelist)
+ and new cells.
+ (scm_egc): Check for scm_estk, scm_estk_ptr not consistent.
+

+ several meaningful values for ints_disabled.
+ (handle_it): More careful about interrupts when saving estk. *
+
+ *scmfig.h (DEFER_INTS): (ALLOW_INTS): (DEFER_INTS_EGC):
+ (ALLOW_INTS_EGC): ints_viol calls changed.
+
+ * ramap.c (array_for_each): (array_map): Always act as if CCLO is

+
+ * patchlvl.h (INIT_FILE_NAME): moved from "scm.c" so it will be
+ updated automatically.
+
+ * Init.scm: renamed Init5c1.scm. The init file-name will
+ henceforth include the version number.

+ CVS).
+
+1998-07-17 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ceval_1): Changed IM_SET to make High C happy.
+
+ * scmfig.h: ioext.c: Added STDC_HEADERS #define and #include
+ <unistd.h> for linux. Allows use of the rename() system call,
+ which works for some filesystems that do not allow multiple links
+ (smbfs).
+
+1998-07-16 Aubrey Jaffer <jaffer@colorage.com>
+
+ * repl.c (repl): changed __TURBOC__ flag to __MSDOS__. This
+ enables the cr/lf fix for DJGPP also.
+ (repl): Enabled cr/lf fix for __HIGHC__ also.
+
+1998-07-16 Radey Shouman <radey@colorage.com>
+
+ * eval.c (lookupcar): Second argument now specifies what to check:
+ LOOKUP_UNDEFP for error on undefined, LOOKUP_MACROP for error on
+ keyword. LOOKUP_UNDEFP and LOOKUP_MACROP are #defined only in

+ level.
+
+1998-07-14 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ENV_PUSH): (ENV_POP): Modified for interrupt safety.
+
+ (ceval_1): (apply): (procedurep): (macroexp1): (make_specfun):

+1998-07-10 Radey Shouman <radey@colorage.com>
+
+ * eval.c (macroexp1): Made sure to call unmemocar before
+ throwing error.
+ (ceval_1): ALLOW_INTS_EGC before returning value.
+
+1998-07-09 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ceval_1): Modifications to allow rewriting of interal
+ DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
+ body of which it is the CAR is macro expanded by m_expand_body,
+ which rewrites internal DEFINE.
+
+ (m_expand_body): Added.
+
+ (m_macroexp1): Added argument to control error checking:
+ m_expand_body may speculatively expand forms in the wrong
+ environments. Made argument number checks conditional on
+ RECKLESS.
+
+ (m_body): Added, error checks bodies and inserts the ISYM tokens.
+
+ (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
+ call m_body.
+
+ (m_cond): (m_case): (m_quote): Modified to avoid destructively changing
+ their argument forms. Since m_expand_body speculatively macro
+ expands forms the process must be reversible.
+
+ (m_ident_eqp): Fixed to use proper environment.
+
+ (renamed_ident): Added DEFER_INTS_EGC.
+
+ Added prototypes for static functions.
+
+1998-07-07 Radey Shouman <radey@colorage.com>
+
+ * eval.c (SPECFUN): Removed -- now the only case.
+ (ceval_1): (m_cont): IM_CONT case removed.
+ (scm_evalatomcar): Added check for tc16_specfun. Made unquoted vector
+ message conditional on RECKLESS.
+
+ * scm.h:
+ * repl.c: IM_CONT removed.
+
+ * sys.c (gc_sweep): Fixed bug in float gc introduced with NUM_HP.
+ (freeprint): Added for debugging.
+
+1998-07-06 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ceval_1): envpp now -1 after estk has been popped,
+ allows better stack tracing.
+
+ * eval.c (ceval_1): Fixed argument number check for closures and
+ made conditional on CAUTIOUS.
+
+ (ceval_1): (evalatomcar): (lookupcar): Moved check for
+ using macro as variable from ceval_1 and evalatomcar to lookupcar.
+
+1998-07-02 Radey Shouman <radey@colorage.com>
+
+ * Init.scm (call-with-current-continuation): Now subr.
+
+ * eval.c (ceval_1): Made CALL-WITH-CURRENT-CONTINUATION an inlined
+ smob, like APPLY. Flushed @CALL-WITH-CURRENT-CONTINUATION.
+
+ ecache allocated lists now no longer passed to apply of asubrs and
+ rpsubrs -- this is not interrupt safe.
+
+ (macroexp1): Added argument number checks for subrs, this gives error
+ messages with unmemoized code.
+
+ * eval.c (ceval_1): Fixed error reporting -- "wrong number of
+ args" was sometimes reported as "wrong type to apply".
+
+ Now pass arglist allocated in ecache for asubrs and rpsubrs with
+ 3+ args.
+
+1998-07-01 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ceval): (ceval_1): (ilookup): (lookupcar): (farlookup):
+ New model of interrupt control for protecting ecache references
+ using DEFER_INTS_EGC, ALLOW_INTS_EGC. These need not be strictly
+ nested, ints are always allowed by ceval_1 before tail-calling a
+ subr.
+ (ceval_1): @apply flushed in favor of a smob denoting apply and
+ understood by the evaluator -- allows ecache allocation of
+ argument lists.
+ (scm_macroexp1): Now checks arity for closures, checking had been
+ broken for non-CAUTIOUS SCM.
+
+ * scmfig.h (DEFER_INTS_EGC): (ALLOW_INTS_EGC): Defined.
+
+ * sys.c (scm_env_cons): (scm_env_cons): (scm_env_cons2):
+ (scm_extend_env): DEFER_INTS replaced with DEFER_INTS_EGC.
+
+ * repl.c (repl_report): At verbose level 3 now reports number of
+ ecache cells migrated and why, also number of ecache garbage
+ collections.
+ (ints_viol): Reports filename and line number of violation, and
+ filename and number of last previous DEFER/ALLOW_INTS.
+
+
+1998-06-23 Radey Shouman <radey@colorage.com>
+
+ * scm.c (int_signal): Now signals error if there is no Scheme
+ handler.
+ (ignore_signals): Changed SIG_IGN to SIG_DFL for SIGINT.
+
+1998-06-22 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ENV_PUSH): Fixed problem introduced during last change:
+ estk was overstepping its bounds.
+
+1998-06-19 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ilookup): (farlookup): (unmemocar): (ceval_1):
+ (id_denote): Wrapped all pointer-chasing of possible ecache cells
+ in DEFER/ALLOW_INTS for safety when interrupt handlers may
+ evaluate Scheme code asynchronously.
+
+ (scm_macroexp1): (m_define): (m_atlet_syntax): Environments now
+ always wrapped when passed to macro expanders.
+
+ (ecache_p): (debug_env_car): (debug_env_cdr): Added for CAREFUL_INTS
+ checking.
+
+ (test_ints): Added when CAREFUL_INTS is defined for checking interrupt
+ safety.
+
+ * repl.c (ints_viol): Now prints file and line number.
+
+1998-06-15 Radey Shouman <radey@colorage.com>
+
+ * scm.h (SCM_ENV_SAVE): (SCM_ENV_RESTORE): Added, to prevent
+ oversights in sys.c.
+
+ * sys.c (scm_env_cons): (scm_env_cons2): Made interrupt safe;
+ return results in global scm_env_tmp, use DEFER/ALLOW_INTS.
+ (scm_extend_env): (scm_env_cons_tmp): Added.
+ (scm_env_acons): Deleted, superseded by scm_extend_env.
+
+ *eval.c (ceval_1): (apply): Replaced and rewrote scm_env_ routines
+ to use new interrupt safe versions. ENV_TMP replaced by
+ scm_env_tmp, it was hard to remember that ENV_TMP might move.
+ CLEAR_ENV_TMP removed since scm_env_tmp will be overwritten almost
+ every time estk is pushed.
+
+1998-06-15 Aubrey Jaffer <jaffer@colorage.com>
+
+ * build.scm (compile-c-files *unknown*): Now uses
+ BATCH:APPLY-CHOP-TO-FIT BATCH:TRY-SYSTEM rather than BATCH-SYSTEM.

+1998-06-12 Radey Shouman <radey@colorage.com>
+
+ * repl.c (scm_execpath): Added ASSERTion to signal error in case
+ malloc fails.
+
+ * subr.c (scm_copybitfield): corrected unsigned declaration of len
+ variable, will now signal errors if END < START.
+ (bigcomp): Changed type of xlen from sizet to long, since
+ it is compared with -1.
+
+1998-06-07 Aubrey Jaffer <jaffer@ai.mit.edu>
+
+ * Init.scm (string-ci->symbol): added (new in "slib/strcase.scm")

+Fri Jun 5 16:01:02 EDT 1998 Aubrey Jaffer <jaffer@scm.colorage.net>
+
+ * patchlvl.h (SCMVERSION): Bumped from 5c0 to 5c1.
+
+1998-06-05 Aubrey Jaffer <jaffer@colorage.com>
+
+ * ANNOUNCE: Removed ftp.cs.indiana.edu:/pub/scheme-repository/

+ as well as *.sl and *.so files.
+
+ * continue.h (setjump): Using (include <signal.h> and) SIG_UNBLOCK
+ for setjump #defines.
+
+ * scm.c (ignore_signals): SIG_UNBLOCK is a better indicator for
+ sigprocmask() than __USE_POSIX.
+
+1998-06-03 Radey Shouman <radey@colorage.com>
+
+ * unif.c (array_inbp): Deleted unused label badarg:
+

+1998-05-30 Aubrey Jaffer <jaffer@ai.mit.edu>
+
+ * build.scm (batch:rebuild-catalog): rewritten from
+ rebuild-catalog.
+ (default-for-platform): new batch-dialect added.

+1998-05-28 Radey Shouman <radey@colorage.com>
+
+ * eval.c (ceval_1): setjmp changed to setjump.
+
+ * continue.h:
+ Changed setjump, longjump to use sigsetjmp, siglongjmp if it
+ looks as though we're POSIX
+
+1998-05-28 Aubrey Jaffer <jaffer@colorage.com>
+
+ * repl.c (handle_it): absorbed wta() call always used with it.
+ (SIGALRM_deferred): renamed from alrm_deferred.

+
+1998-04-03 Ben Caradoc-Davies <bmcd@physics.otago.ac.nz>
+
+ * sys.c (gc_sweep): If a segment is freed during garbage

+ * scmfig.h: Removed support for HAVE_CONFIG_H.
+
+1998-03-09 Radey Shouman <radey@colorage.com>
+
+ * time.c: I found that SCM on Linux uses ftime(), but that ftime()
+ is implemented in glibc as a call to time(). Linux does support
+ gettimeofday(), which does allow 10 msec resolution. I tried
+ using the definition of ftime() using gettimeofday() at the end of
+ time.c (#ifdef freebsd). It worked like a charm.
+
+1998-03-05 Radey Shouman <radey@colorage.com>
+
+ * Init.scm (boot-tail): added `dumped?' argument.
+ * Init.scm (set-vicinities!): added.
+ * time.c (reset_time): Added to fix user time report for dumped

+ the time since dumping.
+ * scm.c (init_scm): Calls reset_time if dumped.
+ * scm.c (scm_find_impl): Wrapper for scm_find_impl_file.

+
+1998-02-09 <amu@mit.edu>
+
+ * scm.h (CGETUN):
+ * sys.c (noop0): I found two places where SCM uses a possibly
+ signed type for characters in a stream and risks confusing '\377'
+ (a legitimate character) with EOF (-1). This patch addresses this
+ problem, and should make SCM's streams completely 8-bit clean.
+
+1998-02-11 Aubrey Jaffer <jaffer@colorage.com>
+
+ * scm.texi (Index): combined indexes into one node. Added use of

+
+ * repl.c (exit_report exit_report): improved.
+ * sys.c (stack_report): improved.
+
+ * scl.c (iint2str): split into two routines. Negative radix
+ argument now forces unsigned conversion.
+
+ * sys.c (alloc_some_heap): heap size variables were confused.
+ heap_cells is now used instead of heap_size.
+
+ * setjump.h (MIN_GC_YIELD NUM_HASH_BUCKETS): moved from scmfig.h.
+
+ * scm.h (THRASH): added.

+Mon, 01 Dec 1997 17:56:43 Andreas Menke <asmenke@bln.de>
+
+ * sys.c (must_malloc must_realloc): Bumps up mtrigger if less than
+ 1/8 of malloc space was reclaimed by GC.
+
+Wed Dec 17 22:40:45 1997 Aaron Ucko <amu@mit.edu>
+
+ * rgx.c (lregcomp): There is a small bug in rgx.c; a few things
+ should be set before sending the pattern buffer to
+ re_compile_pattern(). These fields should be set to zero, which
+ means the bug only appers after memory is reused. This only
+ affects use of GNU regex (i.e., only happens with _GNU_SOURCE
+ defined). cf. regex.info for more information.
+
+Wed Dec 17 22:40:45 1997 Aubrey Jaffer <jaffer@ai.mit.edu>
+
+ * sys.c (free_storage): added fflush for stdout and stderr
+ (because those ports don't get closed).
+
+Sun Nov 30 23:21:05 1997 Aubrey Jaffer <jaffer@martigny.ai.mit.edu>
+

+
+Thu Nov 20 09:45:28 1997 Aubrey Jaffer <jaffer@martigny.ai.mit.edu>
+
