* module/ice-9/vlist.scm (make-block): If we are making a hash table,
allocate it inline with the contents. Otherwise don't even add a
pointer to the block.
(block-hash-table?): New internal accessor.
(block-ref*): Remove. Vhash entries are no longer wrapped.
(block-ref):
(block-hash-table-next-offset):
(block-hash-table-set-next-offset!):
(block-hash-table-ref):
(block-hash-table-set!):
(block-hash-table-add!): Adapt to take content vector explicitly, and
to expect the hash table inline with the contents. Some of these
accessors are new. Adapt callers.
(assert-vlist): New helper.
(vlist-cons): Update comment.
(vhash?): Update scheme to allocate the hash table and chain links
inline with the contents.
(%vhash-fold*, %vhash-assoc): Rewrite to be more performant.
* module/language/tree-il/peval.scm (<operand>, make-operand)
(make-bound-operands, peval): Avoid emitting needless aliases in
degenerate cases of let.
(visit-operand): If we visit an operand with a fresh counter and have
to abort, record that fact.
* test-suite/tests/peval.test ("partial evaluation"): Add a test.
* module/ice-9/vlist.scm (set-block-next-free!): Define this instead of
increment-block-next-free!.
(block-append!): Refactor to take an offset, and only append if the
offset is the next free value, and there is space in the block.
(block-cons): Refactor to not be a loop. The partial evaluator would
have to understand effects analysis in order to be able to unroll it,
and there's at most one recursion.
Recovers the performance loss resulting from the previous commit.
* module/ice-9/vlist.scm: Use define-inlinable instead of define-inline,
to ensure strict argument evaluation. There is a slight performance
penalty, but I hope subsequent hacks make it up.
* module/language/tree-il/cse.scm: New pass, some simple common
subexpression elimination with effects analysis.
* test-suite/tests/cse.test: New test.
* test-suite/Makefile.am:
* module/Makefile.am: Adapt.
* module/language/tree-il/peval.scm: Use effects analysis from (language
tree-il effects) instead of our own constant-expression?. Eagerly
mark assigned lexicals as non-copyable.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Add number? and char?. Add more
numeric predicates. Add character comparators. Add throw, error, and
scm-error.
(*primitive-accessors*): Remove struct-vtable. Though the vtable's
contents may change (through redefinition), its identity does not
change.
(*effect-free-primitives*): Put struct-vtable, number?, and char?
here.
(*multiply-valued-primitives*): Instead of listing singly-valued
primitives, list multiply-valued primitives.
(*bailout-primitives*): New list.
(*negatable-primitives*): New alist.
(*bailout-primitive-table*, *multiply-valued-primitive-table*)
(*negatable-primitive-table*): New tables.
(singly-valued-primitive?): Adapt to
use *multiply-valued-primitive-table*.
(bailout-primitive?, negate-primitive): New exported procedures.
Fixed <http://bugs.gnu.org/11196>.
Reported by Klaus Stehle <klaus.stehle@uni-tuebingen.de>.
* module/srfi/srfi-9.scm (define-record-type): Define the contructor
before TYPE-NAME. Set RTD's constructor field.
* test-suite/tests/srfi-9.test ("record compatibility"): New test
prefix.
* module/language/tree-il/primitives.scm (resolve-primitives!): Resolve
public module-refs to primitives.
* test-suite/tests/tree-il.test: New tests for primitive resolution.
* libguile/srfi-13.c (scm_string_trim, scm_string_trim_right)
(scm_string_trim_both): Take the whitespace fast-path if the char_pred
is scm_char_set_whitespace.
* module/web/http.scm (read-header, split-and-trim, parse-quality-list):
(parse-param-component, parse-credentials, "Content-Type"):
(read-request-line, read-response-line): Use char-set:whitespace
instead of char-whitespace?. It avoids recursing into the VM.
* module/web/server/http.scm (bad-request, http-read): If an exception
is raised while reading a response, write out a 400 Bad Request
response before closing the port.
* module/ice-9/psyntax.scm (do, case): Comment out these definitions,
which are never used and immediately replaced by definitions in
boot-9.scm.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (subst-rename?, rename-old, rename-new,
rename-marks, make-rename): Remove these unused syntax rules.
Fix description of syntax wraps to match current reality.
* module/ice-9/compile-psyntax.scm: Minimize syntax object literals
embedded in psyntax-pp.scm.
* module/ice-9/psyntax.scm: Rename a few variables so that syntax
objects embedded in macros have no lexical bindings, so that their
minimized syntax objects will have no embedded labels. These labels
were the last remaining gensym counters in psyntax-pp.scm.
* module/ice-9/psyntax-pp.scm: Regenerate. It is now less than one
quarter of its previous size! More importantly, this file no longer
contains any gensym counters, which means that in the future, local
changes to psyntax.scm will usually result in only local changes to
psyntax-pp.scm.
* module/language/tree-il.scm (tree-il->scheme): New implementation that
simply calls 'decompile-tree-il'.
* module/language/scheme/decompile-tree-il.scm (choose-output-names,
do-decompile): New internal procedures.
(decompile-tree-il): New and improved implementation. Print source
identifiers where possible, otherwise add minimal numeric suffixes.
Previously we printed the gensyms. Avoid 'begin' in contexts that
provide an implicit 'begin'. Produce 'cond', 'case', 'and', 'or',
'let*', named let, and internal defines where appropriate. Recognize
keyword arguments in 'opts' to disable the production of these derived
syntactic forms, and to optionally strip numeric suffixes from
variable names.
* module/ice-9/compile-psyntax.scm: Disable partial evaluation, letrec
fixing, and primitive expansion when producing psyntax-pp.scm, in
order to produce output as close to the original source as practical.
Disable production of derived syntactic forms as needed during
bootstrap. Strip numeric suffixes from variable names. Adjust
pretty-printing parameters.
* module/ice-9/psyntax-pp.scm: Regenerate. It is now less than half
of the original size.
* module/ice-9/pretty-print.scm (pretty-print): Add new keyword argument
'#:max-expr-width'.
(generic-write): Add new argument 'max-expr-width'. Previously this
was internally defined to the constant value 50.
* module/language/tree-il/analyze.scm (proc-ref?): Change to use less
false-if-exception and more variable-bound?. If a variable is present
in the local module but not bound, assume that it is gettext if it has
the right name. This is to allow for (define _ gettext).
* test-suite/tests/tree-il.test ("warnings"): Update (_ "foo") example.
* module/language/tree-il/peval.scm (peval): Add optimization to
hoist the inner procedure out of e.g.
(lambda args (apply (lambda ...) args))
This commit restores the ability to detect escape-only prompts at
compile-time.
* test-suite/tests/tree-il.test: Update test for prompt with a lambda,
and add a specific test for lambda application.
* module/language/tree-il/canonicalize.scm (canonicalize!): Fix a bug in
which the sense of `escape-only?' was reversed. We never saw this
though, because for other reasons, no prompts were being identified as
escape-only.
* module/language/tree-il/primitives.scm (*primitive-expand-table*):
Don't limit the call-with-prompt to <prompt> transition to lambda
expressions. Instead we can lexically bind the handler, and rely on
peval to propagate a lambda expression.
* module/system/base/pmatch.scm (pmatch): Always wrap with 'let', even
if the expression appears atomic, because in the presence of
'identifier-syntax', we cannot know what an atomic expression will
later expand to. Also use '#:export-syntax' instead of '#:export'
to export 'pmatch'.
* module/srfi/srfi-4.scm, module/srfi/srfi-4/gnu.scm
(define-bytevector-type): Fix definition of <TAG>vector-length when
applied to uniform vectors of different element sizes. Thanks to
Tobias Brandt <tob.brandt@googlemail.com> for reporting this bug.
* test-suite/tests/srfi-4.test: Add tests.
* module/language/tree-il/analyze.scm (proc-ref?): Wrap `variable-ref'
in `false-if-exception'.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string with forward declaration"): New test.
* libguile/posix.c (scm_open_process): Rewrite in C, so as to avoid
allocations and other calls that are not async-signal-safe.
(scm_init_popen, scm_init_posix): Register popen extension.
* module/ice-9/popen.scm: Load the popen extension, to get open-process.
* module/language/tree-il/analyze.scm (gettext?): Rename to...
(proc-ref?): ... this. Add `proc' and `special-name' parameters.
(gettext?): Define in terms of `proc-ref?'.
(ngettext?): New procedure.
(const-fmt): Recognize `ngettext' calls.
(format-analysis)[<down>](check-format-args]: Check
constant-but-non-string 2nd argument in the (not (const-fmt ...))
case.
[check-simple-format-args]: Use `const-fmt'.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string using ngettext", "non-literal format string using
ngettext as N_"): New tests.
("simple-format")["unsupported, ngettext"]: New test.
Fixes <http://bugs.gnu.org/10846>.
Reported by Bruno Haible <bruno@clisp.org>.
* module/language/tree-il/analyze.scm (gettext?): New procedure.
(const-fmt): Add `env' parameter; update callers. Use `gettext?'.
(format-analysis)[check-simple-format-args]: Actually support
gettextized format strings.
* test-suite/tests/tree-il.test ("warnings")["format"]("non-literal
format string using gettext"): Use `gettext' as the procedure name.
("non-literal format string using gettext as _"): New test.
["simple-format"]("unsupported, gettext"): New test.
* module/ice-9/psyntax.scm (decorate-source): Set source properties on
any object that satisfies 'supports-source-properties?'. Previously
we used 'pair?' as the predicate.
(source-annotation): Apply 'source-properties' to _any_ kind of source
expression, where previously only pairs were queried. If the argument
is a syntax-object, apply the source-properties to the syntax-object's
expression.
In the peculiar case of a syntax-object whose expression is also a
syntax-object: previously we would iterate, but with this commit we
now call 'syntax-object-expression' only once.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (syntax-violation): Look for source
properties of 'subform' first. If 'subform' has none, 'form' is used.
Previously, the source information of 'form' was used unless 'form'
_itself_ was '#f', in which case 'subform' was used.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/psyntax.scm (rebuild-macro-output): Fix two bugs that
would cause bogus source properties to be added to vectors and
macro-introduced syntax objects. These bugs were masked by the
limitation that only pairs can be decorated with source properties.
Due to a typo, each vector in the macro output was decorated using the
vector itself as its source. Due to accidental variable capture, each
syntax-object introduced by the macro had its expression decorated
with its own wrap-subst.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/web/response.scm (response-must-not-include-body?): New
function.
* doc/ref/web.texi: Doc the function.
* module/web/server.scm (sanitize-response): Error if we have a body,
but the response type does not permit a body. If we are responding to
a HEAD request, silently drop the body.
* module/ice-9/boot-9.scm (cond, case): Reimplement using syntax-case,
with improved error messages and support for '=>' within 'case' as
mandated by the R7RS. Add warnings for duplicate case datums and
case datums that cannot be meaningfully compared using 'eqv?'.
* module/system/base/message.scm (%warning-types): Add 'bad-case-datum'
and 'duplicate-case-datum' warning types.
* test-suite/tests/syntax.test (cond, case): Update tests to reflect
improved error reporting. Add tests for '=>' within 'case'.
* test-suite/tests/tree-il.test (partial evaluation): Update tests to
reflect changes in how 'case' is expanded.
* doc/ref/api-control.texi (Conditionals): Document '=>' within 'case'.
This reverts parts of a0919aefee ("i18n:
Use Gnulib's `nl_langinfo' module.").
* module/ice-9/i18n.scm (define-simple-langinfo-mapping): Re-add
`default' parameter, and update users accordingly.
