2009-04-07shred,sort,shuf: don't use /dev/urandom by defaultPádraig Brady
Suggestion from Steven Schveighoffer at: http://savannah.gnu.org/patch/?6797 to greatly speed up the random passes done by shred. * gl/lib/randread.c: Default to using the internal pseudorandom generator, rather than reading /dev/urandom * src/shred.c (usage): remove mention of /dev/urandom * src/shuf.c (usage); ditto * src/sort.c (usage): ditto * doc/coreutils.text: Document the new behaviour for aquiring random data.
2009-04-07maint: Clarify ambiguous refs to Linux kernels or GNU/Linux systemsPádraig Brady

2009-01-22shred: change default number of overwrites from 25 to 3Pádraig Brady
* src/shred.c: The concensus is that a default of 3 passes is appropriate for current drive technologies. * src/TODO: Reference Paul Eggert's suggestion of enhancing shred to conform to DoD 5220 rules.
2009-01-16shred: avoid -Wsign-compare warningsPádraig Brady
* src/shred.c: Use already assigned signed variable sizeof_r, rather than the unsigned sizeof(r). Don't use signed integer overflow check that contemporary compilers may remove anyway.

* src/shred.c (ignorable_sync_errno): New function. (dosync): Use it. Based on a patch from Peter O'Gorman.
2008-06-16remove redundant const directivesJim Meyering
In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some missing "const" directives, as well as some new, redundant ones. This removes the redundant ones. Pointed out by Eric Blake. * base64.c, cat.c, chcon.c, chgrp.c, chmod.c, chown.c, comm.c: * cp.c, csplit.c, cut.c, date.c, dd.c, df.c, dircolors.c, du.c: * env.c, expand.c, fmt.c, fold.c, groups.c, head.c, id.c: * install.c, join.c, kill.c, ln.c, ls.c, md5sum.c, mkdir.c: * mkfifo.c, mknod.c, mktemp.c, mv.c, nice.c, nl.c, od.c: * paste.c, pathchk.c, pinky.c, pr.c, ptx.c, readlink.c, rm.c: * rmdir.c, runcon.c, seq.c, shred.c, shuf.c, sort.c, split.c: * stat.c, stty.c, su.c, sum.c, tac.c, tail.c, tee.c, timeout.c: * touch.c, tr.c, truncate.c, tty.c, uname.c, unexpand.c, uniq.c: * wc.c, who.c: Remove redundant const directives. * maint.mk (sc_const_long_option): Don't require redundant "const".

2006-11-27Improve the check for departures from C89, and fix the departuresPaul Eggert
I found. * Makefile.maint (my-distcheck): Also check for C89 compatibility as best we can with GCC. * src/stat.c (PRINTF_OPTION): Omit comma before } in enum declaration; C89 doesn't allow this. * src/dcgen: Don't generate string literals longer than what C89 requires support for. * src/cut.c (usage): Don't use string literals longer than what C89 requires support for. * src/date.c (usage): Likewise. * src/dd.c (usage): Likewise. * src/du.c (usage): Likewise. * src/ls.c (usage): Likewise. * src/od.c (usage): Likewise. * src/readlink.c (usage): Likewise. * src/seq.c (usage): Likewise. * src/shred.c (usage): Likewise.
2006-10-10* src/ls.c (quote_name): Use initializer rather than memset toPaul Eggert
initialize an object to zero. This is easier to read and is less likely to introduce an runtime error due to a mixup. It causes gcc -W to issue a warning, but you can work around this by appending -Wno-missing-field-initializers. * src/pathchk.c (portable_chars_only): Likewise. * src/shred.c (main): Likewise. * src/stty.c (main): Likewise. * src/tr.c (card_of_complement): Likewise. * src/wc.c (wc): Likewise.
2006-09-03Don't include dirname.h, since system.h does it now.Paul Eggert
2006-08-26Include <config.h> unconditionally, since we now assume config.h exists.Paul Eggert
2006-08-25Fix typo in previous checkin; a "&" went missing.Paul Eggert
2006-08-25Rewrite to avoid some unnecessary casts, macros, literals.Paul Eggert
(DEFAULT_PASSES, VERBOSE_UPDATE): Now constants, not macros. (SECTOR_SIZE, SECTOR_MASK): New constants. (fillpattern, dopass, do_wipefd, main): Remove unnecessary casts, and use the SECTOR_* constants when applicable. Check for size < 0 rather than size == -1, since negative-size files are a sign of trouble anyway. (dopass): Assume a continuable error if EIO even if the current position is not a multiple of 512.
2006-08-13* src/shred.c (usage): Don't indent the second line of an item.Jim Meyering
Otherwise, help2man would misformat the output. Reported by Adam Buchbinder in <https://launchpad.net/bugs/48917>.
2006-08-08Use new random-number interface rather than rand-isaac.c.Paul Eggert
Don't include rand-isaac.c; include randint.h and randread.h instead. (RANDOM_SOURCE_OPTION): New enum. (long_opts, usage, main): New option --random-source. (struct irand_state, irand_init, irand32, irand_mod): Remove. All callers changed to use randint interface. (fillrand): Remove. All callers changed to use randread interface. (dopass): Remove dependency on ISAAC buffer size. (genpattern): Don't wipe the random state here. (randint_source): New static var. (clear_random_data): New function. (main): Allocate random source, and arrange to wipe it on exit.
2006-04-19(fillrand): The assertion was way too weak, due toPaul Eggert
what must be a typo. Strengthen it to its intended value. (dopass): Don't use alloca; it's not worth the aggravation here, since it's used only to get a page-aligned buffer, and page alignment doesn't buy us much here. I'm suspicious that alloca causes problems on some hosts, due to a recent bug report by Adam Waltman.
2006-03-26(wipename): Use new last_component, in place of base_name.Jim Meyering
2005-12-27(wipename): Use similar open flags to other places we open directories.Paul Eggert
Don't bother trying to open dir for writing, since POSIX prohibits it.
2005-12-12(struct irand_state, irand_init, irand32, irand_mod): Moved back here,Paul Eggert
from rand-isaac.c.
2005-12-12Include rand-isaac.c rather than rand-isaac.h.Paul Eggert
(fillrand, dopass, main): Undo previous change.
2005-12-10Don't include gethrxtime.h. No longer needed.Jim Meyering
2005-12-10Include rand-isaac.h. Move ISAAC code to rand-isaac.c.Paul Eggert
(fillrand, main): Adjust to the fact that the state size is now runtime-configurable.
2005-09-24Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H', for consistency with ↵Jim Meyering
gnulib.
2005-07-11(wipefile): Always use binary mode. Clearly thisPaul Eggert
never worked right on DOS!
2005-07-03Include fcntl--.h, not unistd-safer.h.Paul Eggert
(wipename, wipe_file): Don't use fd_safer; no longer needed now that we include fcntl--.h.
2005-06-19(usage): Use `file system', not `filesystem'.Jim Meyering
2005-06-17(usage): Clarify that shred works on an ext3 fileJim Meyering
system as long as it's not in data=journal mode. Tiny change by Mark Melahn.
2005-05-14Update FSF postal mail address.Jim Meyering
2005-05-14Update FSF postal mail address.Jim Meyering
2005-04-11Include unistd-safer.h.Paul Eggert
(wipename): Use fd_safer on directory file descriptor. (wipefile): Remove special case for /dev/fd/* on older hosts. It didn't work in general, and wasn't documented. Use fd_safer.
2005-04-09Remove all uses of signals; modern hosts havePaul Eggert
/dev/random and don't need this gorp. Do not include signal.h. (env, sigill_handler, isaac_seed_machdep): Remove. All uses removed.
2005-03-06Remove register keyword.Jim Meyering
2005-02-21Include gethrxtime.h.Paul Eggert
(isaac_seed): Use gethrxtime rather than a mishmash.
2005-01-15(isaac_seed) [HAVE_GETHRTIME]: #if-0 this block,Jim Meyering
because just calling gethrtime evokes an `illegal instruction' failure when compiled with Sun's c89 on Solaris 8 and 9.
2005-01-15(isaac_seed) [HAVE_GETHRTIME]: Don't call ISAAC_SEEDJim Meyering
twice with the same value of `t'. Replace nested #if-#else blocks with #if-#elif-#elif chain.
2004-09-21Remove unused "case 0".Paul Eggert
2004-08-10(usage): "-" is an operand, not an option.Paul Eggert
2004-08-09(wipename): Work even if the directory is writeablePaul Eggert
and not readable. Prefer write access, since this should work better with fdatasync.
