coreutils/src/dd.c, branch v8.22

dd: make status=none suppress all diagnostics

2013-07-19T10:23:12Z

* src/dd.c (STATUS_NONE): Simplify the enum so that it's more general than just suppressing transfer counts. Then test this in all locations where non fatal diagnostics are output. * tests/dd/misc.sh: Ensure the diagnostic about being unable to skip past the end of input is suppressed. * NEWS: Mention the change in behavior. Fixes http://bugs.gnu.org/14897

dd: avoid buffer allocations unless needed

2013-04-14T00:00:45Z

* src/dd.c: Add new static global variable ibuf. (alloc_ibuf, alloc_obuf): New functions factored from dd_copy(). (dd_copy): Call the new functions to allocate memory for ibuf and obuf when necessary. (skip): Likewise. * tests/dd/no-allocate.sh: New test. * tests/local.mk: Reference the test.

maint: improve error messages upon failed read, write, access, close

2013-02-06T15:57:34Z

Note we use "failed to {access,close}" for those single operations, and "error {read,writ}ing" for those partial operation failures. * src/copy.c: Improve error messages for failing read, write and close. * src/cp.c: Improve error messages for failing access. * src/dd.c: Improve error messages for failing read, write and open. * src/head.c: Improve error message for failing close. * src/install.c: Improve error messages for failing access. * src/ln.c: Likewise. * src/mv.c: Likewise. * src/touch.c: Improve error message for failing close. * src/truncate.c: Likewise.

maint: update all copyright year number ranges

2013-01-01T03:51:20Z

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.

dd: fix a printf format mismatch in an error message

2012-12-21T15:57:04Z

* src/dd.c (dd_copy): To print an off_t portably we need to use PRIdMAX and cast to intmax_t, otherwise there could be a mismatch between say a 32 bit off_t and uintmax_t. This was flagged by -Wformat on a 64 bit host when compiling with CFLAGS=-m32.

dd: new option, status=none to suppress output statistics

2012-09-24T14:14:23Z

* src/dd.c (STATUS_NONE): A new bitmask combining all STATUS_ options, thus used to suppress all informational output. (struct symbol_value statuses): Expose the "none" option, corresponding to the STATUS_NONE bitmask above. (print_stats): Return early if STATUS_NONE is specified. Also move the call to gethrxtime() down so that it's only called when needed. (usage): Describe the new options. * doc/coreutils.texi (dd invocation): Likewise. * NEWS: Mention the new feature. * tests/dd/misc.sh: Ensure the new option works.

dd: remove references to the word BLOCKS from help and texi docs

2012-09-18T15:14:05Z

The renaming from BLOCKS to N was done in v8.15-38-g140eca1, and documentation for N was added again in v8.17-26-g4f2e9d5 without noticing that. Now, finally remove the word BLOCKS from the documentation. * src/dd.c (usage): Remove the word BLOCKS. * doc/coreutils.texi (dd invocation): Likewise. Improved by: Bernhard Voelker

doc: document multiplier for dd number options like count=N

2012-06-22T11:16:04Z

* src/dd.c (usage): Add "N" to the description of multipliers. * doc/coreutils.texi (dd invocation): Likewise.

maint: refactor common mode bits used to create files

2012-06-22T10:17:38Z

* src/system.h (MODE_RW_UGO): The new refactored define (666). * src/mkfifo.c: Use the new define. * src/mknod.c: Likewise. * src/split.c: Likewise. * src/system.h: Likewise. * src/touch.c: Likewise. * src/truncate.c: Likewise. Suggested-by: Jim Meyering

maint: handle file sizes more reliably

2012-05-10T09:02:42Z

Problem reported by Samuel Thibault in . * NEWS: Document this. * src/dd.c (skip): Handle skipping past EOF on shared or typed memory objects the same way as with regular files. (dd_copy): It's OK to truncate shared memory objects. * src/du.c (duinfo_add): Check for overflow. (print_only_size): Report overflow. (process_file): Ignore negative file sizes in the --apparent-size case. * src/od.c (skip): Fix comment about st_size. * src/split.c (main): * src/truncate.c (do_ftruncate, main): On files where st_size is not portable, fall back on using lseek with SEEK_END to determine the size. Although strictly speaking POSIX says the behavior is implementation-defined, in practice if lseek returns a nonnegative value it's a reasonable one to use for the file size. * src/system.h (usable_st_size): Symlinks have reliable st_size too. * tests/misc/truncate-dir-fail: Don't assume that getting the size of a dir is not allowed, as it's now allowed on many platforms, e.g., GNU/Linux.
