Changes in 2.0.1 (since 2.0.0):
|
||||
|
||||
* Notable changes
|
||||
|
||||
** guile.m4 supports linking with rpath
|
||||
|
||||
* New modules (see the manual for details)
|
||||
The GUILE_FLAGS macro now sets GUILE_LIBS and GUILE_LTLIBS, which
|
||||
include appropriate directives to the linker to include libguile-2.0.so
|
||||
in the runtime library lookup path.
|
||||
|
||||
** `(ice-9 binary-ports)', XXX
|
||||
** `begin' expands macros in its body before other expressions
|
||||
|
||||
* Memory leak fixes
|
||||
|
||||
close-port leaking iconv_t
|
||||
|
||||
weak hash table pumping
|
||||
|
||||
* doc work

|
||||
|
||||
* guile.m4 supports linking with rpath
|
||||
|
||||
* guile.m4 (GUILE_FLAGS): Also set GUILE_LIBS and GUILE_LTLIBS. Fix
|
||||
documentation.
|
||||
|
||||
* Add omitted exports from `(ice-9 vlist)'.
|
||||
|
||||
* module/ice-9/vlist.scm: Export `vhash-delq' and `vhash-delv'.
|
||||
|
||||
* re-enable the after-gc-hook
|
||||
|
||||
* chi-top-sequence defines macros before expanding other exps
|
||||
This enables support for programs like the following:

|
||||
* flush all input on a read error
|
||||
** REPL reader usability enhancements
|
||||
|
||||
* module/system/repl/repl.scm (flush-all-input): New helper.
|
||||
(prompting-meta-read): Flush all input on a read error, as we could be
|
||||
within some expression or a string or something.
|
||||
The REPL now flushes input after a read error, which should prevent one
|
||||
error from causing other errors. The REPL also now interprets comments
|
||||
as whitespace.
|
||||
|
||||
* repl.scm understands comments
|
||||
** REPL output has configurable width
|
||||
|
||||
* module/system/repl/repl.scm (read-comment, read-scheme-line-comment)
|
||||
(read-scheme-datum-comment): New helpers.
|
||||
(meta-reader): Take a language instead of a reader. If we have a
|
||||
nonwhitespace char, first check to see that it's a comment, and if so,
|
||||
read it off and loop.
|
||||
(prompting-meta-read): Call meta-reader with the lang.
|
||||
The REPL now defaults to output with the current terminal's width, in
|
||||
columns. See "Debug Commands" in the manual for more information on
|
||||
the ,width command.
|
||||
|
||||
* Add ,width meta-command to set screen width in debug output
|
||||
** Better C access to the module system
|
||||
|
||||
terminal-width by default
|
||||
Guile now has convenient C accessors to look up variables or values in
|
||||
modules and their public interfaces. See `scm_c_public_ref' and friends
|
||||
in "Accessing Modules from C" in the manual.
|
||||
|
||||
* man page updates
|
||||
** Added `scm_call_5', `scm_call_6'
|
||||
|
||||

|
||||
See "Fly Evaluation" in the manual.
|
||||
|
||||
* add ice-9 eval-string
|
||||
** Added `scm_from_latin1_keyword', `scm_from_utf8_keyword'
|
||||
|
||||
Fly Evaluation in the manual
|
||||
See "Keyword Procedures" in the manual, for more. Note that
|
||||
`scm_from_locale_keyword' should not be used when the name is a C string
|
||||
constant.
|
||||
|
||||
* add scm_c_public_ref et al
|
||||
** R6RS unicode and string I/O work
|
||||
|
||||
* libguile/modules.h:
|
||||
* libguile/modules.c (scm_public_lookup, scm_private_lookup)
|
||||
(scm_c_public_lookup, scm_c_private_lookup, scm_public_ref)
|
||||
(scm_private_ref, scm_c_public_ref, scm_c_private_ref)
|
||||
(scm_public_variable, scm_private_variable, scm_c_public_variable)
|
||||
(scm_c_private_variable): New helpers to get at variables and values
|
||||
in modules.
|
||||
Added efficient implementations of `get-string-n' and `get-string-n!'
|
||||
for binary ports. Exported `current-input-port', `current-output-port'
|
||||
and `current-error-port' from `(rnrs io ports)', and enhanced support
|
||||
for transcoders.
|
||||
|
||||
"Accessing Modules from C" in the manual
|
||||
** Added `pointer->scm', `scm->pointer' to `(system foreign)'
|
||||
|
||||
* add scm_call_{5,6}
|
||||
These procedure are useful if one needs to pass and receive SCM values
|
||||
to and from foreign functions. See "Foreign Variables" in the manual,
|
||||
for more.
|
||||
|
||||
* doc/ref/api-evaluation.texi (Fly Evaluation): Document
|
||||
scm_call_{5,6,n}.
|
||||
** Added `heap-allocated-since-gc' to `(gc-stats)'
|
||||
|
||||
* Add scm_from_latin1_keyword and scm_from_utf8_keyword
|
||||
Also fixed the long-standing bug in the REPL `,stat' command.
|
||||
|
||||
* doc/ref/api-data.texi: Document new functions. Remind users that
|
||||
scm_from_locale_keyword should not be used when the name is a C string
|
||||
constant. Change formal parameter from `str' to `name'.
|
||||
** Add `on-error' REPL option
|
||||
|
||||
* srfi-9 define-record-type in nested contexts
|
||||
This option controls what happens when an error occurs at the REPL, and
|
||||
defaults to `debug', indicating that Guile should enter the debugger.
|
||||
Other values include `report', which will simply print a backtrace
|
||||
without entering the debugger. See "System Commands" in the manual.
|
||||
|
||||
* Add `get-string-n' and `get-string-n!' for binary and R6RS ports
|
||||
** Enforce immutability of string literals
|
||||
|
||||
* rnrs io ports work
|
||||
Attempting to mutate a string literal now causes a runtime error.
|
||||
|
||||
Export `current-input-port', `current-output-port' and
|
||||
`current-error-port'.
|
||||
** Fix pthread redirection
|
||||
|
||||
Enhance transcoder-related functionality of `(rnrs io ports)'
|
||||
Guile 2.0.0 shipped with headers that, if configured with pthread
|
||||
support, would re-define `pthread_create', `pthread_join', and other API
|
||||
to redirect to the BDW-GC wrappers, `GC_pthread_create', etc. This was
|
||||
unintended, and not necessary: because threads must enter Guile with
|
||||
scm_with_guile, Guile can handle thread registration itself, without
|
||||
needing to make the GC aware of all threads. This oversight has been
|
||||
fixed.
|
||||
|
||||
* module/rnrs/io/ports.scm (transcoder-eol-style)
|
||||
(transcoder-error-handling-mode): Export these.
|
||||
(textual-port?): Implement this procedure and export it.
|
||||
* module/rnrs.scm: Export these here as well.
|
||||
** `with-continuation-barrier' now unwinds on `quit'
|
||||
|
||||
* module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
|
||||
(binary-port?): Treat only ports without an encoding as binary ports,
|
||||
add docstring.
|
||||
(standard-input-port, standard-output-port, standard-error-port):
|
||||
Ensure these are created without an encoding.
|
||||
(eol-style): Add `none' as enumeration member.
|
||||
(native-eol-style): Switch to `none' from `lf'.
|
||||
A throw to `quit' in a continuation barrier will cause Guile to exit.
|
||||
Before, it would do so before unwinding to the barrier, which would
|
||||
prevent cleanup handlers from running. This has been fixed so that it
|
||||
exits only after unwinding.
|
||||
|
||||
* test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
|
||||
(8.2.10 Output ports): Test binary-ness of `standard-input-port',
|
||||
`standard-output-port' and `standard-error-port'.
|
||||
(8.2.6 Input and output ports): Add test for `port-transcoder'.
|
||||
** `string->pointer' and `pointer->string' have optional encoding arg
|
||||
|
||||
doc: Remove "lack of support for Unicode I/O and strings".
|
||||
This allows users of the FFI to more easily deal in strings with
|
||||
particular (non-locale) encodings, like "utf-8". See "Void Pointers and
|
||||
Byte Access" in the manual, for more.
|
||||
|
||||
* doc/ref/api-io.texi (R6RS I/O Ports): Remove 1.8ish comment.
|
||||
** R6RS fixnum arithmetic optimizations
|
||||
|
||||
* add pointer->scm, scm->pointer
|
||||
R6RS fixnum operations are are still slower than generic arithmetic,
|
||||
however.
|
||||
|
||||
* libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
|
||||
functions, useful to pass and receive SCM values to and from foreign
|
||||
functions.
|
||||
** New procedure: `define-inlinable'
|
||||
|
||||
* module/system/foreign.scm: Export the new functions.
|
||||
See "Inlinable Procedures" in the manual, for more.
|
||||
|
||||
* doc/ref/api-foreign.texi (Foreign Variables): Add docs.
|
||||
** New procedure: `exact-integer-sqrt'
|
||||
|
||||
* gc-stats update
|
||||
See "Integer Operations" in the manual, for more.
|
||||
|
||||
add heap-allocated-since-gc; fix ,stat.
|
||||
** "Extended read syntax" for symbols parses better
|
||||
|
||||
* allow ,option on-error report instead of debug
|
||||
In #{foo}# symbols, backslashes are now treated as escapes, as the
|
||||
symbol-printing code intended. Additionally, "\x" within #{foo}# is now
|
||||
interpreted as starting an R6RS hex escape. This is backward compatible
|
||||
because the symbol printer would never produce a "\x" before. The
|
||||
printer also works better too.
|
||||
|
||||
"System Commands" in the manual.
|
||||
* Manual updates
|
||||
|
||||
* Make VM string literals immutable.
|
||||
** GOOPS documentation updates
|
||||
|
||||
* don't redirect pthread_create et al
|
||||
** New man page
|
||||
|
||||
* libguile/bdw-gc.h: Don't do pthread redirects, because we don't want
|
||||
to affect applications' pthread_* bindings.
|
||||
Thanks to Mark Harig for improvements to guile.1.
|
||||
|
||||
* libguile/pthread-threads.h (scm_i_pthread_create)
|
||||
(scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel)
|
||||
(scm_i_pthread_sigmask): Do pthread redirects here, in this internal
|
||||
header.
|
||||
** SRFI-23 documented
|
||||
|
||||
* Document SRFI-23
|
||||
The humble `error' SRFI now has an entry in the manual.
|
||||
|
||||
* doc/ref/srfi-modules.texi: mention that we support SRFI 23
|
||||
* module/ice-9/boot-9.scm (%cond-expand-features): add srfi-23
|
||||
* New modules
|
||||
|
||||
* with-continuation-barrier calls exit(3) _after_ unwinding
|
||||
|
||||
* libguile/continuations.c (scm_handler, c_handler)
|
||||
(scm_c_with_continuation_barrier, scm_with_continuation_barrier):
|
||||
Instead of calling scm_handle_by_message_noexit in the pre-unwind
|
||||
handler, roll our own exception printing in the pre-unwind, and do to
|
||||
exit()-on-quit in the post-unwind handler. This lets the stack unwind
|
||||
at exit-time so that pending dynwinds run.
|
||||
|
||||
* test-suite/tests/continuations.test ("continuations"): Add a test.
|
||||
|
||||
* string->pointer and pointer->string have optional encoding arg
|
||||
|
||||
"Void Pointers and Byte Access" in the manual.
|
||||
|
||||
* Several optimizations for R6RS fixnum arithmetic
|
||||
|
||||
* Move `define-inlinable' into the default namespace
|
||||
|
||||
* module/ice-9/boot-9.scm (define-inlineable): Moved here from SRFI-9.
|
||||
* module/srfi/srfi-9 (define-inlinable): Removed here.
|
||||
|
||||
* doc/ref/api-procedures.texi (Inlinable Procedures): Add subsection
|
||||
about `define-inlinable'.
|
||||
|
||||
* Implement R6RS' `fixnum?' in a smarter way
|
||||
|
||||
* module/rnrs/arithmetic/fixnums.scm (fixnum?): Implemented using
|
||||
bit-twiddling, and using `define-inlinable'.

||||
* libguile/numbers.c (scm_exact_integer_sqrt): New C procedure to
|
||||
compute exact integer square root and remainder.
|
||||
(scm_i_exact_integer_sqrt): New Scheme procedure `exact-integer-sqrt'
|
||||
from the R6RS, imported into core guile.
|
||||
|
||||
* libguile/numbers.h: Add prototypes.
|
||||
|
||||
* module/rnrs/base.scm: Remove broken stub implementation, which would
|
||||
fail badly when applied to large integers.
|
||||
|
||||
* doc/ref/api-data.texi: Add documentation.
|
||||
|
||||
* doc/ref/r6rs.texi: Change documentation for `exact-integer-sqrt' to a
|
||||
stub that xrefs the core docs, as is done for other operations
|
||||
available in core.
|
||||
|
||||
* test-suite/tests/numbers.test: Add tests.
|
||||
|
||||
* NEWS: Add news entries.

ignore SIGPIPE in (system repl server)
|
||||
|
||||
* module/system/repl/server.scm (run-server): Ignore SIGPIPE when we run
|
||||
a server, as otherwise a rudely disconnected client could cause the
|
||||
server to quit. Thanks to John Proctor for the report, and Detlev
|
||||
Zundel for the debugging.

||||
|
||||
* libguile/print.c (symbol_has_extended_read_syntax)
|
||||
(print_normal_symbol, print_extended_symbol, scm_i_print_symbol_name):

|
||||
|
||||
read-extended-symbol handles backslash better, including r6rs hex escapes
|
||||
|
||||
* libguile/read.c (scm_read_extended_symbol): Interpret '\' as an escape
|
||||
character. Due to some historical oddities we have to support '\'
|
||||
before any character, but since we never emitted '\' in front of
|
||||
"normal" characters like 'x' we can interpret "\x..;" to be an R6RS
|
||||
hex escape.
|
||||
|
||||
* test-suite/tests/reader.test ("#{}#"): Add tests.

|
||||
|
||||
symbols with odd characters print better in #{}#
|
||||
|
||||
* libguile/print.c (symbol_has_extended_read_syntax): Use a more
|
||||
general, unicode-appropriate algorithm. Hopefully doesn't cause
|
||||
any current #{}# cases to be unescaped.
|
||||
(print_extended_symbol): Use more appropriate unicode algorithm, and
|
||||
emit unicode hex escapes instead of our own lame escapes.
|
||||
|
||||
* test-suite/tests/symbols.test: Add tests.
