Handle CRLF, NEL, LS and PS to match the new C implementation.
* module/ice-9/suspendable-ports.scm (%read-line): handle alternate line endings
(read-line): use new %read-line
Fixes <https://bugs.gnu.org/29520>.
Reported by Stefan Israelsson Tampe <stefan.itampe@gmail.com>.
* module/language/tree-il/peval.scm (peval)[lift-applied-lambda]: Before
performing eta-conversion, check that the variable(s) passed to the
inner 'apply' are not referenced from the inner lambda, and that the
number of required arguments would not be reduced by the conversion.
* module/system/base/target.scm (cpu-endianness): Add case for "riscv" variants.

This is a followup to <https://bugs.gnu.org/29704>.
* module/srfi/srfi-18.scm (thread-sleep!): When TIMEOUT is a number,
keep it as-is.
* test-suite/tests/srfi-18.test ("thread sleep with number"): Pass 0 as
the timeout.
("thread sleeps fractions of a second"): Pass 0.5 as the timeout.
Fixes <https://bugs.gnu.org/29704>.
Reported by David Beswick <dlbeswick@gmail.com>.
* module/srfi/srfi-18.scm (timeout->absolute-time): New procedure.
(mutex-lock!): Use it in 'thread:lock-mutex' call.
(mutex-unlock!): Use it.
* test-suite/tests/srfi-18.test ("mutex-lock! returns false on timeout")
("mutex-lock! returns true when lock obtained within timeout")
("recursive lock waits")
("mutex unlock is false when condition times out"): Adjust cases where
the 'timeout' parameter is a number so that it's a relative number.
Fixes a bug whereby "guild compile --target=arm-linux-gnueabihf
--from=elisp ... language/elisp/boot.el" would fail with an exception
from 'load-thunk-from-memory' while trying to load (language elisp spec)
from the guile-being-compiled instead of using that of the
guile-for-build.
The problem did not manifest with --from=scheme because (language scheme
spec) happened to be already loaded before we had changed %load-path.
* module/scripts/compile.scm (compile): Add calls to 'lookup-language'.
* module/language/tree-il/compile-cps.scm (adapt-arity): Allow k to be
$kargs for the 1-valued case.
(convert): For single-valued continuations where the definition is
clearly single-valued, avoid making a needless $kreceive and extra
"rest" binding that will just be filled with () and have to be
eliminated later.
* module/language/cps/compile-bytecode.scm (compile-function)
(emit-bytecode):
* module/language/cps/slot-allocation.scm (allocate-slots):
* module/language/cps/optimize.scm (cps-default-optimization-options):
Allow the "lazy vars" optimization, a form of slot precoloring, to be
disabled. It will be disabled at -O0 or -O1, to speed compilation
times.
* module/language/cps/cse.scm (compute-available-expressions):
(compute-equivalent-subexpressions): Improve algorithmic complexity of
CSE by pre-computing the labels whose reads are clobbered by a label's
writes.
* module/language/cps/cse.scm (compute-equivalent-subexpressions): Minor
optimization to reduce the size of equivalent expression keys, and to
avoid some work if an expression has no key.
* module/language/cps/slot-allocation.scm
(compute-reverse-control-flow-order): For graphs without back-edges,
use a simplified computation of reverse control flow order.
* module/language/cps/types.scm (logand): We were computing the wrong
ranges when either argument was negative; a terrible bug!
(logsub): Also fix range when A is negative and B is non-negative.
(ulogand): Tighten up range.
Fixes <https://bugs.gnu.org/29226>.
* libguile/load.c (scm_primitive_load_path): Set 'compiled_thunk' to
SCM_BOOL_F when *scm_loc_fresh_auto_compile is true.
* module/ice-9/boot-9.scm (load-in-vicinity)[load-absolute]: Call
'pre-compiled' only when %FRESH-AUTO-COMPILE is false.
* libguile/Makefile.am (INSTANTIATE): New variable.
(install-data-hook): Use it.
* libguile/libguile-2.2-gdb.scm: Autoload (system vm debug).
Augment %load-path and %load-compiled-path, and reload (system base
types).
* module/system/base/types.scm: Remove #:hide to be 2.0-compatible.
Use (system syntax internal) conditionally when on 2.2.
* module/ice-9/arrays.scm (array-print-prefix): New private function.
* libguile/arrays.c (scm_i_print_array): Reuse (array-print-prefix) from
(ice-9 arrays). Make sure to release the array handle.
* module/ice-9/pretty-print.scm (truncated-print): Support
bitvectors.
Don't try to guess the array prefix but call array-print-prefix from
(ice-9 arrays) instead.
Fix call to print-sequence to support non-zero lower bound arrays.
* test-suite/tests/arrays.test: Test that arrays print properly.
* test-suite/tests/print.test: Test truncated-print with bitvectors,
non-zero lower bound arrays.
* module/ice-9/arrays.scm (array-copy): New function, export.
* module/Makefile.am: Install (ice-9 arrays).
* doc/ref/api-data.texi: Add documentation for (ice-9 arrays).
* libguile/quicksort.i.c: Use signed bounds throughout.
* libguile/sort.c (scm_restricted_vector_sort_x): Fix error calls. Fix
calls to quicksort.
* test-suite/tests/sort.test: Actually test that the sorted results
match the original data. Test cases for non-zero base index arrays for
sort, sort!, and stable-sort!.
This fixes a bug when using ",break":
system/vm/traps.scm:127:31: system/vm/traps.scm:127:31: In procedure <: Wrong type: #f
* module/system/vm/traps.scm (frame-matcher): Check whether END is
true.
* module/oop/goops.scm (opaque-slot?, read-only-slot?): New helpers.
(allocate-slots): Protect opaque and read-only slots by wrapping the
slot accessors instead of relying on struct permissions.
(%compute-layout): Remove opaque-slot case.
* libguile/struct.c: Replace uses of scm_make_struct with
scm_make_struct_no_tail or scm_c_make_struct.
(scm_make_struct_no_tail): Move this function to C instead of Scheme
to be able to deprecate scm_make_struct.
* libguile/struct.h (scm_make_struct_no_tail): New public declaration.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_make_struct): Deprecate.
* libguile/print.c:

scm_make_struct_no_tail.
* test-suite/tests/coverage.test:

make-struct.
* NEWS: Add entry.
Based on a patch by Daniel Hartwig <mandyke@gmail.com>.
* NEWS: Update.
* doc/ref/web.texi (URIs): Fragments are properly part of a URI, so
remove the incorrect note. Add documentation on URI subtypes.
* module/web/uri.scm (uri-reference?): New base type predicate.
(uri?, relative-ref?): Specific predicates.
(validate-uri-reference): Strict validation.
(validate-uri, validate-relative-ref): Specific validators.
(build-uri-reference, build-relative-ref): New constructors.
(string->uri-reference): Rename from string->uri.
(string->uri, string->relative-ref): Specific constructors.
(uri->string): Add #:include-fragment? keyword argument.
* module/web/http.scm (parse-request-uri): Use `build-uri-reference',
and result is a URI-reference, not URI, object. No longer infer an
absent `uri-scheme' is `http'.
(write-uri): Just use `uri->string'.
(declare-uri-header!): Remove unused function.
(declare-uri-reference-header!): Update. Rename from
`declare-relative-uri-header!'.
* test-suite/tests/web-uri.test ("build-uri-reference"):

("uri->string"): Also tests for relative-refs.
* test-suite/tests/web-http.test ("read-request-line"):
("write-request-line"): Update for no scheme in some URIs.
("entity headers", "request headers"): Content-location, Referer, and
Location should also parse relative-URIs.
* test-suite/tests/web-request.test ("example-1"): Expect URI-reference
with no scheme.
* module/web/client.scm (tls-wrap): Use get-bytevector-some instead of
get-bytevector-n, to prevent Guile from attempting to read more bytes
than are available. Normally trying to read data on a shut-down
socket is fine, but but gnutls issues an error if you attempt to read
data from a shut-down socket, and that appears to be a security
property. Fixes HTTPS requests whose responses are smaller than the
port buffer.
