* module/language/tree-il/optimize.scm (peval)[maybe-unlambda]: New
procedures.
Use it to de-duplicate named lambdas. This fixes the scoping bug
described at <https://lists.gnu.org/archive/html/bug-guile/2011-09/msg00019.html>.
* test-suite/tests/tree-il.test ("partial evaluation"): Add tests to
reproduce the bug.
* module/language/tree-il/optimize.scm (peval): Propagate ARGS to BODY
only when all of ARGS are pure. Change APP to use `maybe-unconst' for
its arguments.
* test-suite/tests/tree-il.test ("partial evaluation"): Add tests for
mutability preservation and non-propagation of non-constant arguments
to lambdas.
* module/language/tree-il/optimize.scm (peval)[make-values]: Distinguish
between 1 or another number of values.
[mutable?, make-value-construction, maybe-unconst]: New procedures.
Use it in <let>, <letrec>, <toplevel-define>, and <lambda-case>.
* test-suite/tests/tree-il.test ("partial evaluation"): Add tests
for mutability preservation.
This is a followup to f9c1b8278d ("Tweak
`statprof.test' for faster machines.").
* test-suite/tests/statprof.test ("statistical sample counts within
expected range"): Compile with `#:partial-eval? #f'.
* test-suite/tests/statprof.test ("statistical sample counts within
expected range"): Increase NUM-CALLS and the frequency so that they
are at least a few samples on my new 2.6 GHz laptop.
Thanks to William R. Cook for his excellent tutorial,
<http://softlang.uni-koblenz.de/dsl11/>.
* module/language/tree-il/optimize.scm (optimize!): Call `peval' unless
the #:partial-eval? option asks otherwise.
(peval): New procedure.
* module/language/tree-il/inline.scm: Add comment.
* module/language/tree-il/primitives.scm (*primitive-constructors*): New
variable.
(*effect-free-primitives*): Use it.
(constructor-primitive?): New primitive.
* test-suite/tests/tree-il.test (assert-tree-il->glil): Extend to
support `with-partial-evaluation', `without-partial-evaluation', and
`with-options'.
(peval): New binding.
(pass-if-peval): New macro.
("lexical refs"): Run tests without partial evaluation.
("letrec"): Likewise.
("the or hack"): Likewise.
("conditional"): Likewise, for some tests.
("sequence"): Adjust to new generated code.
("partial evaluation"): New test prefix.
* module/ice-9/match.scm (slot-ref, slot-set!, is-a?): New macros.
* module/ice-9/match.upstream.scm: Update from Chibi-Scheme.
* test-suite/Makefile.am (SCM_TESTS): Add `tests/match.test.upstream'.
* test-suite/tests/match.test (rtd-2-slots, rtd-3-slots): New record
types.
("matches")["records"]: New test prefix.
("doesn't match")["records"]: New test prefix.
Include `match.test.upstream'.
* test-suite/vm/t-match.scm (matches?): Fix `$' example.
* module/texinfo.scm (texi-command-specs, complete-start-command):
Upstream texinfo has aliased `url' to `uref'. Let's do the same.
* test-suite/tests/texinfo.test ("test-texinfo->stexinfo"): Add a test.
* libguile/srfi-1.h:
* libguile/srfi-1.c (scm_srfi1_drop_right, scm_srfi1_take_right): Remove
these internal functions, replacing with Scheme implementations.
* module/srfi/srfi-1.scm (take-right, drop-right): Add these impls from
the reference code. They do the right thing for improper lists,
according to the spec, but they diverge for circular lists. Oh well.
* test-suite/tests/srfi-1.test ("drop-right", "take-right"): Add more
tests.
* module/language/tree-il.scm (tree-il->scheme): Fix incorporation of
`lambda' in a `case-lambda'.
* test-suite/tests/tree-il.test ("tree-il->scheme"): Add a test.
* module/web/request.scm (build-request): Make sure that HTTP/1.1
requests have the Host header set, per RFC 2616 section 9.
* test-suite/tests/web-request.test ("example-1"): Add test.
* libguile/modules.c (resolve_duplicate_binding): Fix unbound -> #f
conversion for the imported bindings. Pass the existing entry in the
import obarray as the resolved var (7th arg), and properly pass #f as
the value (8th arg) if there is no such binding. Fixes
merge-generics; before, the <boolean> type test (indicating no
previous value) was not being triggered. This bug has been present
since 2007 at least, though it was not in 1.8.
* test-suite/tests/modules.test ("duplicate bindings"): Add a test that
the var and val are both #f. These types are used by GOOPS.
* libguile/bytevectors.c (COMPLEX_ACCESSOR_PROLOGUE, COMPLEX_NATIVE_REF,
COMPLEX_NATIVE_SET): New macros.
(bytevector_ref_c32, bytevector_ref_c64): Defined in terms of
`COMPLEX_NATIVE_REF'.
(bytevector_set_c32, bytevector_set_c64): Defined in terms of
`COMPLEX_NATIVE_SET'.
(bytevector_ref_fns): Make `static'.
* test-suite/tests/srfi-4.test ("c32 vectors")["generalized-vector-ref",
"generalized-vector-set!", "generalized-vector-ref, out-of-range",
"generalized-vector-set!, out-of-range"]: New tests.
("c64 vectors")["generalized-vector-ref", "generalized-vector-set!",
"generalized-vector-ref, out-of-range",
"generalized-vector-set!, out-of-range"]: New tests.
* libguile/read.c (scm_read_sexp): Don't confuse `#{.}#' with `.' for
the purpose of reading dotted pairs. Thanks to CRLF0710 for the
report.
* test-suite/tests/reader.test ("#{}#"): Add test.
* module/language/tree-il/primitives.scm (+, *, cons*): In the case of
just one argument (the identity case), expand to (values x) instead of
just x. Fixes values truncation in that case.
(values): Likewise remove (values x) -> x translation, as the compiler
will do it for us, and this fixes (values (values 1 2)).
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Handle
`values' in a push context here.
* test-suite/tests/tree-il.test ("values"): Add some tests.
http://savannah.gnu.org/bugs/?33362
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Rename
from flatten, as it really just takes a particular case. Instead of
iteratively compiling lambda cases through `comp', tail-call through
flatten-lambda-case. This allows code to see which case it's being
compiled in. Take advantage of that to limit the self-tail-call
optimization to self-calls to the same case -- otherwise we might be
jumping to a label without having reserved the right number of
locals.
(flatten-lambda): Adapt the caller.
* test-suite/tests/compiler.test ("case-lambda"): Add a test.
* test-suite/tests/weaks.test: Add tests.
* libguile/hashtab.c (scm_hash_fn_set_x): Fix updates to weak-value hash
tables to not deadlock inside the alloc lock.
* module/rnrs/io/ports.scm (open-file-input-port)
(open-file-output-port): Ensure the resulting ports are binary when no
transcoder is specified.
* test-suite/tests/r6rs-ports.test: Remove superfluous global change of
`%default-port-encoding' and accompanying comment.
("7.2.7 Input Ports"): Add test ensuring `open-file-input-port' opens
a binary port when no transcoder is specified.
("8.2.10 Output ports"): Strengthen existing `open-file-output-port'
binary-ness test by setting `%default-port-encoding' to "UTF-8".
* test-suite/tests/r6rs-ports.test
(call-with-bytevector-output-port/transcoded): New helper procedure.
("8.2.6 Input and output ports"): Use that helper procedure.
(encoding-error-predicate): New helper procedure.
("8.2.12 Textual Output"): Add tests for `put-char' and `put-string'
exception behavior on encoding errors.
(For use by guile-tools)
* module/ice-9/getopt-long.scm: Use (ice-9 optargs) so we can use
define*.
(process-options): Add stop-at-first-non-option parameter. When
this is true, stop processing when we hit a non-option (so long as
that non-option isn't something that resulted from the unclumping of
a short option group).
(getopt-long): Add #:stop-at-first-non-option keyword; pass it on to
process-options.
* test-suite/tests/getopt-long.test ("stop-at-first-non-option"): New
test (for the above).
* test-suite/tests/regexp.test (char-code-limit): Define a local version
of this recently removed definition. Hopefully that's the only use
of it though!
* module/rnrs/io/ports.scm (open-file-output-port): Handle `no-fail'
file option.
(with-i/o-filename-conditions): Use `with-throw-handler' instead of `catch'.
(with-i/o-port-error,
with-textual-output-conditions. with-textual-input-conditions): New
exception-conversion helpers.
(put-char, put-datum, put-string, display): Use
`with-textual-output-conditions' instead of `with-i/o-encoding-error'
to get proper conditions in case of write errors.
(get-char, get-datum, get-line, get-string-all, lookahead-char):
Likewise, for the input case.
* test-suite/tests/r6rs-ports.test (pass-if-condition, test-file,
make-failing-port): New helpers.
("8.2.10 Output ports"): Add some tests for `open-file-output-port'.
("8.2.9 Textual Input"): Add tests read error conditions.
("8.2.12 Textual Output"): Add tests for write error conditions.
("8.3 Simple I/O"): Add tests for conditions, `call-with-input-file'
and `call-with-output-file'.
Thanks to Mark H. Weaver for pointing this out.
* libguile/ports.c (CONSUME_PEEKED_BYTE): New macro.
(get_utf8_codepoint): New variable `pt'. Use
`scm_peek_byte_or_eof'/`CONSUME_PEEKED_BYTE' pairs instead of
`scm_get_byte_or_eof'.
* test-suite/tests/ports.test ("string ports")[#xc2 #x41 #x42, #xe0 #xa0
#x41 #x42, #xf0 #x88 #x88 #x88]: Fix to conform to Unicode 6.0.0.
[#xe0 #x88 #x88]: Remove test.
[#xf0 #x80 #x80 #x41]: New test.
* libguile/ports.c (update_port_lf): Handle EOF.
(get_utf8_codepoint, get_iconv_codepoint): New functions.
(get_codepoint): Use them.
(scm_i_set_port_encoding_x): Don't open conversion descriptors when
ENCODING is "UTF-8".
* libguile/print.c (display_string_as_utf8, display_string_using_iconv):
New functions.
(display_string): Use them.
* test-suite/tests/ports.test ("string ports")[#xc2 #x41 #x42]: Add a
note that this is not the wrong behavior per Unicode 6.0.0.
* module/ice-9/boot-9.scm (map, for-each): Implement in Scheme instead
of C. There are boot versions before `cond' is defined.
(map-in-order): Define this alias here instead of in evalext.h.
* libguile/eval.c: Stub out the map and for-each definitions to just
call into Scheme.
* libguile/evalext.c: Remove map-in-order definition.
* module/srfi/srfi-1.scm: Replace all calls to map1 with calls to map.
(map, for-each): Define implementations here, in Scheme, instead of in
C.
* test-suite/tests/eval.test (exception:wrong-length, "map"): Update the
expected exception for mapping over lists of different lengths.
* libguile/srfi-1.h:
* libguile/srfi-1.c: Remove map and for-each definitions. Remove the
bit that extended the core `map' primitive with another method: the
right way to do that is with modules.
