https://git.shady.money/coreutils/atom?h=v8.262016-11-04T20:38:32Zdd: warn about counts specified with confusing 0x prefix2016-11-04T20:38:32ZPádraig BradyP@draigBrady.com2016-11-04T16:55:58Zurn:sha1:c6656eed6ae9536812012a1b0d0b31ec960acf23
* src/dd.c (parse_integer): Suggest to use "00x" instead of "0x",
which is significant for the "count", "seek", and "skip" operands.
* tests/dd/misc.sh: Add a test case.
Fixes http://bugs.gnu.org/24874
all: 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, ...);
doc: fix ambiguous multiplier info in dd man page2016-08-18T10:58:39ZPádraig BradyP@draigBrady.com2016-08-18T10:58:39Zurn:sha1:3e71b0657760825d4c3a356df67a59fc6bc57ec6
* src/dd.c (usage): Add a comma which is significant for
the rewrapping done in man pages.
doc: suggest dd "sync" flag to maximize "nocache" effectiveness2016-01-13T11:16:39ZPádraig BradyP@draigBrady.com2016-01-11T22:31:45Zurn:sha1:6ceb7ef87fdf138f0553f32a95567920cc51ae1a
doc/coreutils.texi (dd invocation): Add oflag=sync to the streaming
example. Also reference the "direct" flag. Mention this is only
a request to the system.
* src/dd.c (usage): Mention the "sync" flag along with "nocache".
Also mention that it's only a request to drop the cache.
* THANKS.in: Add reporter Francois Rigault.
maint: avoid a sc_long_lines failure in recent commit2016-01-01T14:24:19ZPádraig BradyP@draigBrady.com2016-01-01T14:23:01Zurn:sha1:aaf8d80f1d31289fd71a4be2749ba033693369f3
* src/dd.c (alloc_ibuf): Shorten line length.
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.
dd: append spaces to shorter status=progress line2015-12-31T22:09:36ZPaul Eggerteggert@cs.ucla.edu2015-12-31T22:09:05Zurn:sha1:2dab6cd3c2e18eb574b24e54fba86a33c80b6a27
Problem noted by Pádraig Brady in: http://bugs.gnu.org/22277#8
Also, make the output a bit more precise while we're at it.
* NEWS: Document this.
* src/dd.c (previous_time): Remove, replacing with ...
(next_time): New var. All uses changed.
This avoids some rounding errors, and should be a bit faster.
(newline_pending): Remove, replacing with ...
(progress_len): New var. All uses changed.
This lets us keep track of how many trailing spaces to append.
(print_xfer_stats): Get the time first thing, so that it's
closer to being correct. Count the bytes output, and append
trailing spaces if needed. Add remarks to translators about
translation lengths.
dd: summarize in --human-readable format too2015-12-31T19:49:55ZPaul Eggerteggert@cs.ucla.edu2015-12-31T19:43:09Zurn:sha1:8f9bf300174afa9b29027542ec59892f610c08e4
Problem reported by Linda Walsh in: http://bugs.gnu.org/17505
* NEWS: Document this.
* doc/coreutils.texi (dd invocation): Use a simpler script.
Adjust output example to match new behavior.
* src/dd.c (human_size): Remove.
All uses changed to use human_readable and ...
(human_opts): ... this new constant.
(abbreviation_lacks_prefix): New function.
(print_xfer_stats): Use it. Output both --si and --human-readable
summaries, but only if they have prefixes.
* tests/dd/reblock.sh, tests/dd/stats.sh: Test new behavior.
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.
copy,dd: simplify and optimize NUL bytes detection2015-10-27T17:25:12ZPádraig BradyP@draigBrady.com2015-10-22T13:34:08Zurn:sha1:9459d9d8112fe7816022665b5016c2014bb625f3
* src/factor.c: Move LIKELY() definition to...
* src/system.h: ...here.
(is_nul): Reimplement with a version that doesn't
require a sentinel after the buffer, and which calls
down to (the system optimized) memcmp.
Performance analyzed at http://rusty.ozlabs.org/?p=560
* src/dd.c (alloc_obuf): Simplify the is_nul() call by
not needing to write the sentinel.
* src/copy.c (sparse_copy): Likewise.
(copy_reg): Simplify the buffer allocation by avoiding
consideration of the sentinel in the buffer size calculation.
