‘unlinkat’ is used for both unlinking regular files
and removing empty directories.
* configure.ac: Detect if ‘unlinkat’ exists.
* doc/ref/posix.texi (File System): Document why there is no
‘rmdirat’ procedure, and document the ‘delete-file-at’ procedure.
* libguile/filesys.c
(scm_rmdir): Adjust the docstring here as well.
(scm_delete_file_at): Define a Scheme binding to ‘unlinkat’.
* libguile/filesys.h (scm_delete_file_at): Make ‘scm_delete_file_at’
part of the C API.

* configure.ac: Detect existence of fchmodat.
* libguile/filesys.c (scm_chmodat): New procedure.
* libguile/filesys.h (scm_chmodat): Make it part of the API.
* test-suite/tests/filesys.test ("chmodat"): Test it.

* configure.ac: Detect if ‘renameat’ is defined.
* libguile/filesys.c (scm_renameat): Define a Scheme binding
to the ‘renameat’ system call.
* doc/ref/posix.texi (File System): Document it.
* libguile/filesys.h (scm_renameat): Make it part of the C API.
* test-suite/tests/filesys.test ("rename-file-at"): New tests.

* configure.ac: Detect whether ‘symlinkat’ exists.
* libguile/filesys.c (scm_symlinkat): Define a Scheme binding
when it exists.
* libguile/filesys.h: Make the binding part of the public C API.
* doc/ref/posix.texi (File System): Document the binding.
* test-suite/tests/filesys.test ("symlinkat"): Test it.

* configure.ac: Detect whether ‘readlinkat’ is defined.
* libguile/filesys.c (scm_readlink): Support file ports
when ‘readlinkat’ exists.
(scm_init_filesys): Provide ‘chdir-ports’ when it exists.
* doc/ref/posix.texi (File System): Document it.
* test-suite/tests/filesys.test ("readlink"): Test it.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* configure.ac: Check for ‘fchdir’.
* libguile/filesys.c
(scm_chdir): Support file ports.
(scm_init_filesys): Report support of file ports.
* doc/ref/posix.texi (Processes): Update accordingly.
* doc/ref/guile.texi: Add copyright line for new documentation in this
patch and later patches.
* test-suite/tests/filesys.test ("chdir"): Test it.

The definition and the declaration for scm_integer_from_mpz
do not match
* libguile/integers.c (scm_integer_from_mpz): takes const mpz_t arg
No callers need to be changed.
Since Guile requires a C99 compiler, we can rely on signal handlers
returning void, not int.
* configure.ac: remove AC_TYPE_SIGNAL
* libguile/scmsigs.c (SIGRETTYPE): remove SIGRETTYPE
(take_signal): returns void
(scm_sigaction_for_thread): presumes handlers return void
These are important for reliable networking, since they prevent network
operations from hanging indefinitely.
* libguile/socket.c (scm_init_socket): Define SO_RCVTIMEO and
SO_SNDTIMEO.
(scm_getsockopt, scm_setsockopt): Include SO_RCVTIMEO and SO_SNDTIMEO in
docstring and handle them.
* doc/ref/posix.texi (Network Sockets and Communication): Document them.

On MinGW, 'system' uses a non-posix shell that does not handle
apostrophe as a quoting character. For this test, quoting a command-line
with double quotes allows it to be run with both /bin/sh and cmd.exe.
* test-suite/tests/c-api.test (egrep): use double quotes when
quoting command line
The standalone egrep script has been deprecated by GNU grep.
'grep -E' is the suggested replacement.
* test-suite/tests/c-api.test (egrep): replace egrep with grep -E
* module/srfi/srfi-35.scm (condition): Use 'make-exception' instead of
'make-compound-condition', which is unbound in this module.
* test-suite/tests/srfi-35.test ("syntax")["compound condition,
hygienic macro expansion"]: New test.
* doc/ref/sxml.texi (7.21.4 Transforming SXML): Adds a mention to the
module to be imported for the procedures introduced in this section of
the documentation..

Avoids spurious "error in finalization thread: Success" messages when
the finalization pipe gets closed.
* libguile/finalizers.c (finalization_thread_proc): Return when 'data.n'
is zero.
MinGW ACL-based permissions don't follow POSIX standard, so
'chmod' has unexpected behavior.
* test-suite/tests/ftw.test (mingw?): new define
("file system fold: EACCES"): skip test on MinGW
This is the same strategy as used for the 'accept4' bindings introduced
in 6e0965104c.
* libguile/posix.c (scm_pipe): Rename to...
(scm_pipe2): ... this. Add an optional 'flags' parameter and honor it.
(scm_pipe): Rewrite as a call to 'scm_pipe2'.
* libguile/posix.h (scm_pipe2): New declaration.
* test-suite/tests/posix.test ("pipe"): New tests.
* configure.ac: Look for 'pipe2'.
* NEWS: Update.
This makes the docstring attached to the curried function being defined
rather than the result of its application until a function that runs the
body is obtained, fixing
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=50068
Locations are stored in tree-il records in "source vector" form, but
`location-string' was rendering these as <unknown-location>.
* module/system/base/message.scm (location-string): Support locations
passed as a file/line/column vector.
Fixes <https://bugs.gnu.org/55596>.

and Jack Hill <jackhill@jackhill.us>.
* libguile/posix.c (start_child): Close OUT only if it's greater than 2.
* test-suite/tests/posix.test ("system*")["exit code for nonexistent file"]
["https://bugs.gnu.org/55596"]: New tests.
