coreutils/src/sync.c, branch v8.26Mirror of https://https.git.savannah.gnu.org/git/coreutils.git/
https://git.shady.money/coreutils/atom?h=v8.262016-10-16T11:23:55Zall: use die() rather than error(EXIT_FAILURE)2016-10-16T11:23:55ZPádraig BradyP@draigBrady.com2016-10-15T22:10:35Zurn:sha1:492dcb2eb191b844a2fd5e51db3eed85289bea1f
die() has the advantage of being apparent to the compiler
that it doesn't return, which will avoid warnings in some cases,
and possibly generate better code.
* cfg.mk (sc_die_EXIT_FAILURE): A new syntax check rule to
catch any new uses of error (CONSTANT, ...);
maint: update all copyright year number ranges2016-01-01T14:10:41ZPádraig BradyP@draigBrady.com2016-01-01T14:10:41Zurn:sha1:b16e999f553b682e74e0a56750f649da05130c4f
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
all: avoid quoting file names when possible2015-11-04T23:30:14ZPádraig BradyP@draigBrady.com2015-11-01T18:53:26Zurn:sha1:08e8fd7e38f2dae7c69c54eb22d508b6517e66e5
Quote file names using the "shell-escape" or "shell-escape-always"
methods, which quote as appropriate for most shells,
and better support copy and paste of presented names.
The "always" variant is used when the file name is
embedded in an error message with surrounding spaces.
* cfg.mk (sc_error_shell_quotes): A new syntax check rule
to suggest quotef() where appropriate.
(sc_error_shell_always_quotes): Likewise for quoteaf().
* src/system.h (quotef): A new define to apply shell quoting
when needed. I.E. when shell character or ':' is present.
(quoteaf): Likewise, but always quote.
* src/*.c: Use quotef() and quoteaf() rather than quote()
where appropriate.
* tests/: Adjust accordingly.
build: port to AIX2015-06-06T07:46:13ZPaul Eggerteggert@cs.ucla.edu2015-06-06T00:33:54Zurn:sha1:079652ee6b5d3987525ce225518a15253fc9d319
Problems reported by Michael Felt, and and part of this fix taken
from code suggested by Pádraig Brady in:
http://bugs.gnu.org/20733#112
* configure.ac (stdbuf_supported): Check for warnings, and
for -fPIC and -shared, for AIX.
* src/stat.c (STRUCT_STATVFS): Define to struct statvfs64 if
STATFS is statvfs64.
* src/sync.c (sync_arg) [_AIX]: Open in write mode,
since AIX fsync doesn't work on read-only file descriptors.
* tests/misc/wc-parallel.sh: Skip test if xargs -P does not work.
maint: avoid new coverity warnings2015-05-29T23:41:09ZPádraig BradyP@draigBrady.com2015-05-29T14:33:59Zurn:sha1:b9842a615366b47cbd0739d97f2dd2679dfbb3a8
* src/sync.c (sync_arg): Initialise variable to avoid
unitialized access if assert is disabled.
* src/head.c (elide_tail_bytes_file): Support this function
with ---presume-input-pipe and larger files,
which regressed with commit v8.23-47-g2662702.
(elide_tail_lines_file): Likewise.
* src/dd.c (dd_copy): Explicitly don't try to ftruncate()
upon failure to lseek() (the existing check against
st_size was already protecting that).
* src/factor.c (factor_using_squfof): Assert (only when
linting due to performance) to avoid the implication of
divide by zero.
* src/od.c (read_block): Remove dead code.
* src/tac.c (tac_seekable): Likewise.
* src/ls.c (gobble_file): Likewise.
sync: support syncing specified arguments2015-01-28T10:50:45ZGiuseppe Scrivanogscrivano@gnu.org2015-01-25T00:33:45Zurn:sha1:8b2bf5295f353016d4f5e6a2317d55b6a8e7fd00
* m4/jm-macros.m4 (coreutils_MACROS): Check for syncfs().
* man/sync.x: Add references to syncfs, fsync and fdatasync.
* doc/coreutils.texi (sync invocation): Document the new feature.
* src/sync.c: Include "quote.h".
(AUTHORS): Include myself.
(MODE_FILE, MODE_DATA, MODE_FILE_SYSTEM, MODE_SYNC): New enum values.
(long_options): Define.
(sync_arg): New function.
(usage): Describe that arguments are now accepted.
(main): Add arguments parsing and add support for fsync(2),
fdatasync(2) and syncfs(2).
* tests/misc/sync.sh: New (and only) test for sync.
* tests/local.mk: Reference the new test.
* AUTHORS: Add myself to sync's authors.
* NEWS: Mention the new feature.

Run "make update-copyright" and then...
* tests/sample-test: Adjust to use the single most recent year.
* tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message,
so that year is updated automatically in future.
doc: output correct --help references with --program-prefix2014-09-19T10:24:05ZPádraig BradyP@draigBrady.com2014-09-18T13:50:47Zurn:sha1:8e93dc629727140e950a709008f9a17ca461af63
* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME
as a parameter, so that consistent references are made to online docs
and texinfo nodes, when a --program-prefix is in place. Note the
man pages don't need this fix as they're generated before the program
prefix is used.
* NEWS: Mention the improvements in references to online documentation.
maint: prefer 'return status;' to 'exit (status);' in 'main'2014-09-09T03:48:44ZPaul Eggerteggert@cs.ucla.edu2014-09-08T23:31:14Zurn:sha1:8defcee49be881f8c7b8327f07b988fbe5c7171d

Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.
