Thanks to Bruno Haible for his suggestions. See
<http://lists.gnu.org/archive/html/bug-libunistring/2010-09/msg00007.html>,
for details.
* libguile/ports.c (register_finalizer_for_port): Always register a
finalizer for PORT.
(finalize_port): Close ENTRY->input_cd and ENTRY->output_cd.
(scm_new_port_table_entry): Initialize the `input_cd' and `output_cd'
fields.
(utf8_to_codepoint): New function.
(get_codepoint): Rewrite to use `iconv' instead of libunistring.
(scm_i_set_port_encoding_x): Initialize the `input_cd' and `output_cd'
fields.
(update_port_lf): Move upward. Use `switch' instead of `if's.
* libguile/ports.h (scm_t_port)[input_cd, output_cd]: New fields.
* libguile/print.c (codepoint_to_utf8, display_string): New functions.
(display_character): Use `display_string'.
(write_combining_character): Likewise.
(iprin1): Use `display_string' instead of `scm_lfwrite_str', and
`display_character' instead of `scm_putc'.
(write_character): Likewise.
(write_character_escaped): New function.
* test-suite/tests/encoding-escapes.test ("display output
escapes")["Rashomon"]: Use lower-case escapes.
["fake escape"]: New test.
* libguile/numbers.c (scm_is_integer): Infinities are not integers, per
the R6RS.
(scm_even_p, scm_odd_p): Passing an infinity to even? or odd? is an
error.
* test-suite/tests/numbers.test ("integer?"): Adapt test.
("expt"): Add tests for +inf.0 and -inf.0 exponents.
* NEWS: Add NEWS entries.
* libguile/private-options.h (SCM_HUNGRY_EOL_ESCAPES_P): New private
option.
* libguile/read.c: Define SCM_HUNGRY_EOL_ESCAPES_P, defaulting to #f.
(skip_intraline_whitespace): New helper.
(scm_read_string): If SCM_HUNGRY_EOL_ESCAPES_P,
skip_intraline_whitespace after an escaped EOL.
* test-suite/tests/reader.test ("read-options"): Add test.
* libguile/numbers.c (scm_expt): Fix bug that caused expt to throw an
exception whenever the base was exact and the exponent was an
inexact integer, e.g. (expt 5 6.0).
(scm_expt): Fix bug that caused expt to introduce spurious imaginary
parts in the result when the base was an inexact negative real and
the exponent was an integer, e.g. (expt -1.0 2)
(scm_integer_expt, scm_expt): Change behavior of (integer-expt 0 -1),
and therefore also (expt 0 -1), to return NaN, per R6RS (actually,
R6RS says we should throw an exception or return an "unspecified
number object", but for now we use NaN). Formerly we returned 0, per
R5RS. R5RS claims that 0^x=0 for all non-zero x, but that's
mathematically incorrect, and probably an oversight.
(scm_integer_expt): Consistently throw a wrong-argument-type exception
when the exponent is inexact. Formerly, it didn't always check this
if the base was 0, 1, or -1.
* test-suite/tests/numbers.test ("integer-expt", "expt"): Add tests.
* module/web/request.scm (read-request-body, write-request-body): Rename
from read-request-body/bytevector and
write-request-body/bytevector. Remove the /latin-1 variants, as they
were unused and a bad idea.
* module/web/response.scm (read-response-body, write-response-body):
Likewise.
* module/web/server/http.scm (http-read, http-write): Adapt to
request/response change.
* test-suite/tests/web-request.test:
* test-suite/tests/web-response.test: Update tests.
* module/web/http.scm (declare-symbol-list-header!): New helper.
("Connection"): Redefine as a header list.
("Allow", "Content-Encoding", "Accept-Ranges"): Redefine as symbol
lists.
* test-suite/tests/web-http.test:
* test-suite/tests/web-response.test: Adapt tests.
* module/web/http.scm (parse-media-type): Parse media types as symbols.
(parse-key-value-list, parse-param-component, parse-param-list):
Change kons to val-parser. Always parse keys as symbols, and always
either cons, if there is a val, or just have the key, if there is no
val. Easier to explain and just as correct.
(declare-param-list-header!, declare-key-value-list-header!): Adapt to
key-list and param-list kons change.
("Cache-Control", "Pragma", "Transfer-Encoding", "Accept", "Expect")
("TE"): Likewise, adapt.
("Content-Type"): Param keys are symbols.
* module/web/http.scm (declare-header!): No need to specify `sym', as it
can be derived from `name'. Change to take parser, validator, and
writer as positional arguments, and multiple? as a keyword.
(parse-header): Change to take the header as a symbol already, and
just return the parsed value. All headers are symbols now, including
unknown headers. I feel OK doing this given that the symbol GC works
now.
(lookup-header-decl): Only look up headers by symbol.
(read-header): Adapt to parse-header change.
(valid-header?, write-header): Adapt to all headers being symbols.
(split-header-names, list-of-header-names?, write-header-list):
Represent all header names as symbols.
(declare-opaque-header!, declare-date-header!)
(declare-string-list-header!, declare-header-list-header!)
(declare-integer-header!, declare-uri-header!)
(declare-quality-list-header!, declare-param-list-header!)
(declare-key-value-list-header!, declare-entity-tag-list-header!):
Change to be functions instead of syntax, and no need to specify the
symbolic name. Update all header declarations accordingly.
* module/web/request.scm (validate-headers):
* module/web/response.scm (validate-headers): Adapt to all headers being
symbols.
* test-suite/tests/web-http.test (pass-if-parse, pass-if-any-error)
(pass-if-parse-error): Update for parse-header change.
("general headers"): Update header list examples to be all symbols.
* module/language/ecmascript/compile-tree-il.scm (compile-tree-il):
generate correct tree-il for construction of new objects.
* test-suite/tests/ecmascript.test (ecompile): Add pattern with EXPECTED
omitted.
("compiler"): test whether we generate new objects correctly.

* module/ice-9/format.scm (format): Add port and format-string as formal
arguments. Seems also to have triggered a reindent. Formally
deprecate omitting the port, as it's usually an error.
* test-suite/tests/format.test ("format basic output")
("format basic output", "~{ iteration"): Fix up tests that omitted the
destination port.
* module/ice-9/threads.scm (parallel, par-mapper): Rewrite in terms of
`future' and `touch'.
* test-suite/tests/threads.test ("par-map", "par-for-each"): New test
prefixes.
* doc/ref/api-scheduling.texi (Parallel Forms): Add cross-ref to
futures. Recommend against the `n-' variants.
* module/ice-9/futures.scm (process-future!): Use `call-with-values'
when invoking `(future-thunk future)'.
* test-suite/tests/future.test ("futures")["multiple values"]: New test.
* module/web/http.scm (list-of-strings?, write-list-of-strings): Move
definitions up.
(split-header-names, list-of-header-names?, write-header-list): New
helpers.
(declare-header-list-header): New helper.
(cache-control): Use split-header-names for private and no-cache.
(trailer): Use declare-header-list-header to parse known headers to
symbols.
(vary): Likewise, use split-header-names et al.
* test-suite/tests/web-http.test ("general headers"): Add a test.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Don't emit
a self-label, because when we can't match the args for a lexical call,
we have no space to shuffle args and jump.
(flatten): Apply the self-tail-call optimization to optional args
too, but only if the procedure is fix-allocated. If we can't apply the
optimization, use the normal tail-call sequence.
* test-suite/tests/optargs.test ("lambda* inits"): Add tests.
* libguile/posix.c (scm_total_processor_count,
scm_current_processor_count): New functions.
* libguile/posix.h (scm_total_processor_count,
scm_current_processor_count): New declarations.
* test-suite/tests/posix.test ("nproc"): New test prefix.
* doc/ref/posix.texi (Processes): Document `total-processor-count' and
`current-processor-count'.
* module/language/elisp/compile-tree-il.scm (access-variable)
(reference-variable, set-variable!): Handle globally-bound non-special
variables.
(bind-lexically?): Create lexical bindings for flet and flet*.
* module/language/elisp/runtime.scm (reference-variable, set-variable!):
Handle globally-bound non-special variables.
(built-in-func): Set the variable directly instead of storing the
function in a fluid.
* module/language/elisp/runtime/subrs.scm (funcall): Call apply
directly.
* test-suite/tests/elisp-compiler.test ("Function Definitions")["flet
and flet*"]:

* module/language/elisp/compile-tree-il.scm (reference-with-check)
(compile-without-void-checks, want-void-check?): Remove.
(compile-function, compile-pair): Use `reference-variable' instead of
`reference-with-check'.
(compile-defvar): Only set `sym' if `sym' is not bound to a bound
fluid, rather than requiring that its value be `void'.
(process-options!): Remove `#:disable-void-check' option handling.
* module/language/elisp/runtime.scm (void)
(reference-variable-with-check): Remove.
(ensure-fluid!): Use an undefined fluid as the initial value for
global variables.
* module/language/elisp/runtime/function-slot.scm (without-void-checks):
Don't import or re-export.
* module/language/elisp/runtime/macros.scm (prog1, cond, or, dolist):
Don't use `without-void-checks'.
* module/language/elisp/runtime/subrs.scm (symbol-value)
(symbol-function, apply): Use `reference-variable' instead of
`reference-variable-with-check'.
(makunbound, fmakunbound, boundp, fboundp): Unset the variable's fluid
(or the variable itself, if it isn't bound to a fluid).
* test-suite/tests/elisp-compiler.test ("Variable
Setting/Referencing")["disabled void check (all)", "disabled void
check (symbol list)", "without-void-checks"]: Remove.

Use #{`}#, #{,}# and #{,@}# as the quasiquote, unquote and
unquote-splicing operators, respectively. Previously they were named
escaping.
* module/language/elisp/compile-tree-il.scm (unquote?): Change "\," to
"#{,}#".
(unquote-splicing): Change "\,@" to "#{,@}#".
(#{compile-`}#): Rename from #{compile-\`}#.
* module/language/elisp/runtime/function-slot.scm: Import #{compile-`}#
instead of #{compile-\`}#, and re-export as #{`}# instead of as
#{\`}#.
* module/language/elisp/parser.scm (quotation-symbols):
* test-suite/tests/elisp-compiler.test ("Eval", "Quotation"):
* test-suite/tests/elisp-reader.test ("Parser"): Change "\`", "\,", and
"\,@" to "#{`}#", "#{,}#" and "#{,@}#", respectively.
* test-suite/tests/elisp-compiler.test (compile-test): Add
`pass-if-equal' to the list of literal identifiers

* libguile/fluids.c (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New functions.
(fluid_ref): New function; like scm_fluid_ref, but will not throw an
error for unbound fluids.
(scm_fluid_ref, swap_fluid): Use `fluid_ref'.
* libguile/fluids.h (scm_make_undefined_fluid, scm_fluid_unset_x)
(scm_fluid_bound_p): New prototypes.
* libguile/vm-i-system.c (fluid_ref): If fluid is unbound, jump to
`vm_error_unbound_fluid'.
* libguile/vm-engine.c (VM_NAME)[vm_error_unbound_fluid]: New error
message.
* test-suite/tests/fluids.test ("unbound fluids")["fluid-ref of unbound
fluid", "fluid-bound? of bound fluid", "fluid-bound? of unbound
fluid", "unbound fluids can be set", "bound fluids can be unset"]: New
tests.
* module/web/http.scm: Add commentary.
(parse-quality): Allow .NNN to be interpreted as 0.NNN.
* test-suite/tests/web-http.test ("request headers"): Add a test.
* configure.ac: Add checks for `sched_setaffinity' and
`sched_getaffinity'.
* doc/ref/posix.texi (Processes): Document `getaffinity' and
`setaffinity'.
* libguile/posix.c (cpu_set_to_bitvector,
scm_getaffinity)[HAVE_SCHED_GETAFFINITY]: New functions.
(scm_setaffinity)[HAVE_SCHED_SETAFFINITY]: New function.
* libguile/posix.h (scm_getaffinity, scm_setaffinity): New declarations.
* test-suite/tests/posix.test ("affinity"): New test prefix.
* module/rnrs/base.scm (error, assert): Define -- they were missing.
(assertion-violation): Properly treat a #f `who' argument.
* module/rnrs/conditions.scm (condition): Use `assertion-violation'
instead of the undefined `raise'.
(define-condition-type): Fix for multiple fields.
* test-suite/tests/r6rs-conditions.test: Test accessors of a
multiple-field condition. Also import `(rnrs base)' to allow
stand-alone running of the tests; apparently the `@' references
scattered throughout the R6RS modules make the libraries sensitive to
their load order -- for instance, trying to load `(rnrs conditions)'
before `(rnrs base)' is loaded fails.
* module/rnrs/records/inspection.scm: Use `assertion-violation' instead
of an explicit `raise'.
* module/rnrs/records/syntactic.scm (process-fields): Use
`syntax-violation' instead of bogus invocations of `error'.

structure to refer to character offsets, not byte offsets. Fixes bug
31650.
* test-suite/tests/regexp.test: Add a test.
* module/rnrs/enums.scm (enum-set-union, enum-set-intersection,
enum-set-difference): Compare enum-set universes with `equal?' to support
sets generated using constructor syntax bound by `define-enumeration'.
* test-suite/tests/r6rs-enums.test (enum-set-union, enum-set-intersection,
enum-set-difference): New test cases for syntactically-generated sets.
* libguile/r6rs-ports.c (make_bip, make_cbip, make_bop, make_cbop): Lock
the port table.
* libguile/r6rs-ports.c (make_bop): Let the returned extraction
procedure refer to the port's buffer instead of the port itself. This
fixes a segfault if the port is closed before the extraction procedure
is called.
(bop_proc_apply): Adapt accordingly.
* test-suite/tests/r6rs-ports.test (8.2.10 Output ports): Add testcase
for extraction after close.

This results in a 17% improvement in the execution time of the "+" and
"-" benchmarks for fixnums.

form of syntax errors. Adapt all tests.
* test-suite/tests/srfi-17.test: Likewise.
* libguile/numbers.c (scm_iuint2str): Add an assertion on the domain of
the radix. Use the number_chars table to write the string, instead of
doing strange math. Same effect, though.
(mem2uinteger, char_decimal_value): Change logic to allow all ascii
alphabetic chars as decimals, not just a-f. Thanks to Nils Gey for the
report.
* test-suite/tests/numbers.test ("number->string"): Add some tests.
