2015-01-01maint: update all copyright year number rangesPádraig Brady
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.
2014-01-02maint: update all copyright year number rangesBernhard Voelker
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.

2010-07-23randread: run 2x faster on 64-bit hosts, don't assume no padding bitsPaul R. Eggert
* gl/lib/rand-isaac.c: Remove the I/O; this belongs elsewhere. Add support for ISAAC64. Port to hosts with padding bits. Add self to author list. Include <limits.h>, for CHAR_BIT. Don't include string.h, sys/time.h, unistd.h. (min, just): New functions. (IF32): New macros. (ind, ISAAC_STEP, isaac_refill, mix, isaac_init, isaac_seed): Add support for ISAAC64. Port to hosts with padding bits. (ind): Now an inline function rather than a macro; no need for it to be a macro with modern compilers. (ISAAC_STEP): Renamed from isaac_step, since it's not function-like. Don't bother to pass args that are always the same. All uses changed. (ISAAC_STEP, ISAAC_SEED): Move to inside the only function body that can use it. (ISAAC_MIX): Renamed from isaac_mix, since it's now a macro and is no longer function-like. Don't bother saving and restoring state; no longer needed now that we're not a function. All uses changed. (isaac_seed_start, isaac_seed_data, isaac_seed_finish): Remove. (isaac_seed): Take just the one arg; the caller now sets s->m. * gl/lib/rand-isaac.h: Use _GL_RAND_ISAAC_H to protect, instead of RAND_ISAAC_H. Try out " #" rather than "# " for indenting. (ISAAC_BITS_LOG, ISAAC_BITS): New macros. (ISAAC_WORDS_LOG): Renamed from ISAAC_LOG. (isaac_word): New type. All uses of uint32_t changed to isaac_word, to support ISAAC64. (struct isaac_state): Rename member MM to M, and make it public. (isaac_seed, isaac_refill): Adjust to new API. * gl/lib/randread.c: Include sys/time.h. (get_nonce): New function, containing the nonce stuff that used to be in rand-isaac.c but better belongs here. (randread_new): Use it. * gl/modules/randread (Depends-on): Add inline. * gl/modules/randread-tests: New file. * gl/tests/test-rand-isaac.c: New file.
2010-07-20randread: use /dev/urandom to seed, not just getpid etcPaul R. Eggert
* gl/lib/rand-isaac.c (isaac_seed_start): New arg SEEDED. (isaac_seed): New args FD and BYTES_BOUND. Read from FD if possible. Don't bother with low-quality sources if FD has enough bytes. * gl/lib/rand-isaac.h: New size_t arg for isaac_seed. * gl/lib/randread.c: Include fcntl.h, unistd.h. (NAME_OF_NONCE_DEVICE): New #define. (nonce_device): New static var. (randread_new): Use nonce device if available.
2010-01-01maint: update all FSF copyright year lists to include 2010Jim Meyering
Use this command: git ls-files | grep -v COPYING \ | xargs env UPDATE_COPYRIGHT_USE_INTERVALS=1 \ build-aux/update-copyright

2007-10-07Convert coreutils' rand*.{c,h,m4} into modules.Jim Meyering
First step: move these files to gl/lib: * lib/rand-isaac.c, lib/rand-isaac.h * lib/randint.c, lib/randint.h * lib/randperm.c, lib/randperm.h * lib/randread.c, lib/randread.h Step 2: add modules/rand* and remove now-unneeded .m4 files. * gl/modules/randint: New file. * gl/modules/randperm: New file. * gl/modules/randread: New file. * m4/randint.m4: Remove file. * m4/randperm.m4: Remove file. * m4/randread.m4: Remove file. Step 3: use the new modules * bootstrap.conf (gnulib_modules): Add randint and randperm. * m4/prereq.m4 (gl_RANDINT, gl_RANDREAD, gl_RANDPERM): Don't require; These have been removed. (gl_ROOT_DEV_INO): Don't require; already handled via bootstrap.conf.
