* module/language/tree-il.scm (<tree-il>): Remove pre and post fields
from <dynwind>. A dynwind now assumes that in normal entry and exit,
that the code runs the winders and unwinders using <seq> and
<let-values> and such things.
(parse-tree-il, unparse-tree-il, make-tree-il-folder, pre-post-order):

cause the consumer to run in the wrong dynamic context.
If the producer is singly-valued and the consumer just has a rest arg,
reduce to "let" and cons up a list in the consumer. This may reduce
further.
* test-suite/tests/peval.test ("partial evaluation"): Add a test.
* module/language/tree-il.scm (tree-il-fold): Implement using
make-tree-il-folder. This is an incompatible change: there is no more

* module/system/vm/debug.scm (find-program-debug-info): Return #f if the
string is "", as it is if we don't have a name. Perhaps
elf-symbol-name should return #f in that case...
* test-suite/tests/rtl.test: Add some tests.
* libguile/procprop.h:
* libguile/procprop.c (scm_procedure_documentation): Move here from
procs.c, and to make the logic more similar to that of procedure-name,
which allows RTL programs to dispatch to rtl-program-documentation.
* libguile/programs.c (scm_i_rtl_program_documentation):
* libguile/programs.h:

arities of a function.

description.
* module/system/vm/linker.scm (make-linker-object):
(linker-object-section-symbol):
(linker-object-symbols*): Create a symbol to the start of a linker
object. Hide it from the external linker-object-symbols* accessor.
(segment-kind, count-segments): Sections without SHF_ALLOC don't get
segments.
(collate-objects-into-segments): Allow for #f segment types. If two
sections have the same type and flags, leave them in the same order.
(align): Allow for 0 alignment.
(add-elf-objects): New helper: puts the ELF data structures (header,
segment table, and section table) in sections of their own. This
lends a nice clarity and conceptual unity to the linker.
(relocate-section-header, allocate-segment): Lay out segments with
congruent, contiguous addresses, so that we can just mmap the file and
if debugging sections that are not in segments are present, they can
be lazily paged in if needed by the kernel's VM system.
(link-elf): Refactor to use the new interfaces.
* test-suite/tests/linker.test: Update to expect the additional sections
for the header and section table.
* module/system/vm/elf.scm: Add commentary.

<elf> instead of all the fields separately.

section indexes when creating ELF sections.
* module/system/vm/linker.scm (fold-values): New helper.
(alloc-segment, relocate-section-header): Arrange to set segment and
section indexes.
(find-shstrndx): New helper, replaces compute-sections-by-name. Now
that sections know their indexes, this is easier.
(allocate-elf, write-elf): New helpers, factored out of link-elf.
Easier now that sections have indexes.
(link-elf): Simplify. Check that the incoming objects have sensible
numbers.
* test-suite/tests/linker.test: Update to set #:index on the linker
objects.
* module/Makefile.am:
* module/system/vm/linker.scm: New file, split out of (system vm elf).

names, instead of make-elf-string-table and elf-string-table-intern.
* module/system/vm/elf.scm: Remove linking capabilities.
(string-table-ref): Export.
* module/language/objcode/elf.scm (bytecode->elf): Adapt to use (system
vm linker).
* test-suite/tests/linker.test: New test.
* module/web/uri.scm (uri-encode): the hexadecimal percent-encoding %HH
is now uppercased as suggested by RFC3986:
"For consistency, URI producers and normalizers should use
uppercase hexadecimal digits for all percent-encodings."
* test-suite/tests/web-uri.test ("encode"): update tests.
* test-suite/tests/ports.test ("BOM not discarded unless at start of
UTF-16 stream", "BOM not discarded unless at start of UTF-32 stream"):
Adjust tests to reflect the fact that, in the absence of a BOM, big
endian will be used by default for the "UTF-16" and "UTF-32"
encodings.
Reported by Samuel Thibault <samuel.thibault@gnu.org>
and Peter Simons <simons@cryp.to>.
* test-suite/tests/00-socket.test ("AF_INET6/SOCK_STREAM"): Throw
`unresolved' when `bind' throws EADDRNOTAVAIL.
* libguile/filesys.c (scm_sendfile): In Linux-style sendfile(2) code, if
EINTR or EAGAIN occurs, set result to 1 (not 0) so that we actually
keep going. In non-sendfile(2) code, deal gracefully with short reads
due to EOF.
* test-suite/tests/filesys.test ("sendfile"): Use 'let*' to guarantee
the needed order of operations: write (test-file) and then read it.
Add code to check the written data (not just the returned length) in
all tests, including the cases that hit EOF prematurely.
* libguile/filesys.c (scm_sendfile)[HAVE_SYS_SENDFILE_H &&
HAVE_SENDFILE]: Compare RESULT with C_COUNT. Loop until C_COUNT bytes
have been sent.
* doc/ref/posix.texi (File System): Update the description. Explain the
new semantics.
* test-suite/tests/filesys.test ("sendfile"): Rewrite using
`pass-if-equal'. Check the return value for all the tests.
["file with offset past the end", "file with offset near the end"]:

containing the code previously found in 'scm_open_file', but modified
to accept the new 'guess_encoding' and 'encoding' arguments.
(scm_open_file): Now just a simple wrapper that calls
'scm_open_file_with_encoding'.
(scm_i_open_file): New implementation of 'open-file' that accepts
keyword arguments '#:guess-encoding' and '#:encoding', and calls
'scm_open_file_with_encoding'.
(scm_init_fports_keywords): New initialization function that gets
called after keywords are initialized.
* libguile/fports.h (scm_open_file_with_encoding,
scm_init_fports_keywords): Add prototypes.
* libguile/init.c (scm_i_init_guile): Call 'scm_init_fports_keywords'.

'open-output-file', 'call-with-input-file', 'call-with-output-file',
'with-input-from-file', 'with-output-to-file', and
'with-error-to-file', that accept keyword arguments '#:binary',
'#:encoding', and (for input port constructors) '#:guess-encoding'.
* doc/ref/api-io.texi (File Ports): Update documentation.
* test-suite/tests/ports.test ("keyword arguments for file openers"):
Add tests.
* libguile/ports.c (scm_i_unget_bytes): New static function.

reflect the new reality: it is no longer a subset of (rnrs io ports).
* test-suite/tests/ports.test ("unget-bytevector"): Add test.
* libguile/fports.c (scm_open_file): Do not scan for coding
declarations. Replace 'use_encoding' local variable with
'binary'. Update documentation string.
* module/ice-9/psyntax.scm (include): Add the same file-encoding
logic that's used in compile-file and scm_primitive_load.
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-io.texi (File Ports): Update docs.
* test-suite/tests/ports.test: Change "open-file HONORS file coding
declarations" test to "open-file IGNORES file coding declaration".
* test-suite/tests/coding.test (scan-coding): Use 'file-encoding' to
scan for the encoding, since 'open-input-file' no longer does so.
* libguile/array-map.c: new function rafill, like scm_array_fill_int,
but factors GVSET out of the loop. Use it in scm_array_fill_x instead of
scm_array_fill_int.
* test-suite/tests/arrays.test: add test for array-fill! with stride != 1.

(get_iconv_codepoint): Pass new 'mode' parameter to
'scm_i_port_iconv_descriptors'.
(get_codepoint): After reading a codepoint at stream start, record

appropriate.

scm_utf32le_bom): New static const arrays.
(decide_utf16_encoding, decide_utf32_encoding): New static functions.
(scm_i_port_iconv_descriptors): Add new 'mode' parameter. If the
specified encoding is UTF-16 or UTF-32, make that precise by deciding
what byte order to use, and construct iconv descriptors based on the
precise encoding.
(scm_i_set_port_encoding_x): Record that we are now at stream start.
Do not open the new iconv descriptors immediately; let them be

* module/ice-9/psyntax.scm (case-lambda, case-lambda*): Allow a

Remove tests that depend on GNU iconv behavior. We will add them back
when we have portable BOM support.
* libguile/ports.c (get_iconv_codepoint): Rewrite to fix a bug and
improve efficiency and clarity. Previously, it incorrectly assumed
that iconv would never consume input without producing output, which
led to a buffer overrun and subsequent assertion failure. This
happens when a byte-order mark is consumed by iconv at the beginning
of the stream when using the UTF-16 or UTF-32 encodings.
