Fixes <http://bugs.gnu.org/18988>.
Reported by Chris Vine <chris@cvine.freeserve.co.uk>.
* libguile/filesys.c (scm_select): Clarify handling of signal
interruptions.
* doc/ref/posix.texi (Ports and File Descriptors): Adjust accordingly.
* libguile/load.c (scm_i_mirror_backslashes): New function.
(scm_init_load_path): Call it to produce MS-Windows file names
with forward slashes.
(FILE_NAME_SEPARATOR_STRING): Define as "/" on all platforms.
* libguile/load.h (scm_i_mirror_backslashes): Add prototype.
* libguile/init.c (scm_boot_guile): Call scm_i_mirror_backslashes
on argv[0].
* libguile/filesys.c (scm_getcwd): Call scm_i_mirror_backslashes
on the directory name returned by getcwd.
* test-suite/tests/ports.test ("file name separators"): New test.
* libguile/iselect.h:
* libguile/threads.c:
* libguile/deprecated.h: Rely on Gnulib for sys/select.h.
* libguile/filesys.c: Rely on Gnulib for 'lstat' and 'mkstemp'.
* libguile/private-gc.h (SCM_DOUBLECELL_ALIGNED_P): Remove; unused.
* libguile/filesys.c (MAX, MIN): Move definitions here, from
private-gc.h.
(scm_sendfile, scm_readdir): Adapt uses of SCM_MAX and SCM_MIN to use
MAX or MIN.
* 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"]:
New tests.
* configure.ac: Check for <sys/sendfile.h> and `sendfile'.
* libguile/filesys.c (scm_sendfile): New function.
* libguile/filesys.h (scm_sendfile): New declaration.
* test-suite/tests/filesys.test ("sendfile"): New test prefix.
* doc/ref/posix.texi (File System): Document `sendfile'.
* libguile/filesys.c (is_file_name_separator): New helper, as in
load.c.
(scm_dirname, scm_basename, scm_i_relativize_path): Use
is_file_name_separator.
* libguile/filesys.c (scm_system_file_name_convention): New function.
Exported to Scheme only.
* module/ice-9/boot-9.scm (file-name-separator?, absolute-file-name?):
New predicates.
(file-name-separator-string): New global variable.
(in-vicinity): Use the new procedures.
(load-user-init, try-module-autoload): Use file-name-separator-string.
(load-in-vicinity): Update canonical->suffix. Consistently use the
term "file name" throughout.
* module/ice-9/psyntax.scm (include): Use global `absolute-file-name?'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* libguile/filesys.c (scm_i_relativize_path): Don't attempt to
canonicalize when encountering an entry of IN_PATH that is the empty
string.
* test-suite/tests/ports.test (with-load-path): New macro.
("%file-port-name-canonicalization"): New test prefix.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
* libguile/ports.c (scm_putc, scm_puts):
* libguile/ports.h (scm_putc_unlocked, scm_puts_unlocked): Separate into
_unlocked and locked variants. Change all callers to use the
_unlocked versions.
* libguile/arrays.c (scm_i_read_array):
* libguile/backtrace.c (display_backtrace_body):
* libguile/filesys.c (scm_readdir)
* libguile/i18n.c (chr_to_case):
* libguile/ports.c (register_finalizer_for_port):
* libguile/posix.c (scm_nice):
* libguile/stacks.c (scm_make_stack): Clean up a number of
set-but-unused vars. Thanks to Douglas Mencken for the report.
* libguile/numbers.c (scm_log, scm_exp): Fix a few #if cases that should
be #ifdef.
* libguile/filesys.h:
* libguile/filesys.c (scm_i_relativize_path): New function, moved here
from fports.c. Internal for now; we can make it external though if
people like its interface.
* libguile/fports.c (fport_canonicalize_filename): Move all of the
tricky bits to filesys.c. Also fixes a bug in which a delimiter wasn't
stripped.
* libguile/posix.h:
* libguile/posix.c (scm_utime): Add optional nanosecond arguments. This
is an incompatible change on the C level, but it's unlikely people are
using this POSIX wrapper function, because they would just use the
POSIX function directly. Hopefully, anyway.
* module/system/base/compile.scm (call-with-output-file/atomic):
Propagate source timestamps to targets with nanosecond precision, if
available. Fixes build on systems with ext4 filesystems.
* libguile/filesys.c (scm_stat2scm):
* module/ice-9/posix.scm (stat:atimensec, stat:mtimensec)
(stat:ctimensec): Add three new elements to Scheme stat structures,
for nanosecond-level timestamps.
* configure.ac: Add checks for utimensat, and for nanosecond fields in
struct stat. We should switch to using Gnulib things for these,
though.
* doc/ref/posix.texi (File System): Add documentation for utime's
additional arguments, and nanosecond stat timestamp accessors.
* m4/gnulib-cache.m4: Add `inet_ntop' and `inet_pton'.
* configure.ac: Don't check for `inet_ntop' and `inet_pton'.
* libguile/socket.c (scm_inet_pton, scm_inet_ntop): Compile regardless
of `HAVE_INET_PTON' and `HAVE_INET_NTOP' respectively.
* libguile/filesys.c: Use <stdlib.h> instead of <canonicalize.h>.
