From scripts/compile pushed default assumption of #:from as 'scheme down
into system/base/compile where filename and first line can be used to
deduce intended "from" language. If first line of a file is of the form
#lang ecmascript
then the file is assumed consist of source language "ecmascript".
* module/scripts/compile.scm (compile): changed default #:from to #f
from 'scheme
* module/system/base/compile.scm(lang-from-port, %file-extension-map,
add-lang-extension, lang-extension-for): added global
%file-extension-map with accessor lang-extension-for and updater
add-lang-extension. Also, added lang-from-port to parse first line,
looking for #lang.
* test-suite/tests.scm: added "load-lang" test.
* test-suite/Makefile.am(SCM_TESTS): added tests/load-lang.test
* doc/ref/api-macros.texi: make the macro expand to the literal
date, not to a call to the date function. The example previously
did not actually need eval-when and did not show the intended
effect.
Fixes <https://bugs.gnu.org/60522>.
Reported by Sascha Ziemann <ceving@gmail.com>.
* module/language/tree-il/primitives.scm (make-vector): Return #f when
passed an incorrect number of arguments.
* test-suite/tests/peval.test ("partial evaluation"): Add tests.

Fixes <https://bugs.gnu.org/59321>.
Reported by <hylophile@posteo.de>.
Some systems provide "/proc/self/fd" which is a directory containing an
entry for each open file descriptor in the current process. We use this
to limit the number of close() calls needed to ensure file descriptors
aren't leaked to the child process when forking.
* libguile/posix.c (close_inherited_fds_slow):
(close_inherited_fds): New static helper functions.
(scm_spawn_process): Attempt to close inherited file descriptors
efficiently using 'close_inherited_fds', falling back to the brute-force
approach in 'close_inherited_fds_slow'.
* NEWS: Update.
This test reproduces the error from <https://bugs.gnu.org/56493>, and
passes with the workaround which was merged in commit
c7fa78fc75.
* test-suite/tests/eval.test ("avoid frame-local-ref out of range"): New
test.

The spelling mistake is a clear fix, but the Arrays fix might not be as
obvious. Previously, with the "arrays" alias, the @ref macro would
render a superfluous period after the word "arrays", rendering (at least
within Emacs) as:
you may wish to use see arrays. instead.

If we got interrupted while waiting on our condition variable, we unlock
the kernel mutex momentarily while executing asynchronous operations
before putting us back into the waiting queue.
However, we have to retry acquiring the mutex before getting back into
the queue, otherwise it's possible that we wait indefinitely since
nobody could be the owner for a while.
* libguile/threads.c (lock_mutex): Try acquring the mutex after signal
interruption.
