maint: prefer rawmemchr to memchr when easy

2021-09-15T22:08:28Z

* bootstrap.conf (gnulib_modules): Add rawmemchr. * src/csplit.c: Include idx.h. * src/csplit.c (record_line_starts): * src/head.c (elide_tail_lines_pipe): * src/shuf.c (next_line): * src/split.c (lines_split): * src/tail.c (pipe_lines): * src/wc.c (wc_lines): Prefer rawmemchr to memchr when rawmemchr is easy. * src/csplit.c (load_buffer): * src/head.c (struct linebuffer): Make room for a 1-byte sentinel.

maint: update all copyright year number ranges

2021-01-01T16:36:09Z

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.

maint: use getrandom, not getentropy

2020-06-01T22:54:50Z

This makes for one Gnulib module less, and at runtime there’s typically just one getrandom syscall instead of several for large nonces. * gl/lib/randread.c: Include sys/random.h instead of sys/time.h and unistd.h. (get_nonce): Use getrandom, not getentropy. * gl/modules/randread (Depends-on): Depend on getrandom, not getentropy. * src/shred.c (main): * src/shuf.c (main): * src/sort.c (random_md5_state_init): Say "getrandom" rather than "getentropy" in (unlikely) diagnostic.

maint: use getentropy and new tempname modules

2020-06-01T05:39:48Z

Update gnulib submodule to latest and use its new features. Gnulib’s new getentropy module means coreutils can now assume getentropy instead of approximating it, badly in some cases. Gnulib’s improvements to the tempname module mean coreutils no longer needs to maintain private patches. * bootstrap.conf (gnulib_modules): Remove gettimeofday. * gl/lib/randread.c (NAME_OF_NONCE_DEVICE): Remove. (get_nonce): Return success indicator. Remove bytes_bound arg. All callers changed. Rewrite by using getentropy instead of reading the nonce device and falling back on gettimeofday. Fail if getentropy fails. (randread_new): Return NULL (setting errno) if get_nonce fails. All callers changed. * gl/lib/tempname.c.diff, gl/lib/tempname.h.diff: * gl/modules/tempname.diff: Remove. * gl/modules/randread (Depends-on): Depend on getentropy, not gettimeofday. * src/ptx.c (swallow_file_in_memory): * src/shuf.c (read_input): Adjust to read_file changes in Gnulib. * src/shred.c (main): * src/shuf.c (main): * src/sort.c (random_md5_state_init): Diagnose the new form of randread_new failures: randread_new can fail now when !random_source, meaning getentropy failed.

all: improve parsing of numeric arguments

2019-10-22T22:04:43Z

This addresses a longstanding "update all callers" FIXME in lib/xstrtol.c, by having programs check that numbers do not have unknown suffixes. The problem was also reported for 'shuf' by my student Maggie Huang while reimplementing a shuf subset in Python as an exercise in UCLA Computer Science 35L: https://web.cs.ucla.edu/classes/fall19/cs35L/assign/assign3.html This patch also improves the portability of the code to unusual platforms where ULONG_MAX < SIZE_MAX. * NEWS: Mention user-visible changes. * src/chgrp.c (parse_group): * src/chroot.c (parse_additional_groups): * src/du.c (main): * src/install.c (get_ids): * src/join.c (string_to_join_field): * src/ls.c (decode_switches): * src/md5sum.c (split_3): * src/shuf.c (main): * src/sort.c (specify_nthreads): * src/uniq.c (size_opt, main): Use uintmax_t instead of unsigned long, for portability to oddball platforms where unsigned long is not wide enough. * src/du.c (main): * src/expr.c (mpz_init_set_str) [!HAVE_GMP]: * src/install.c (get_ids): * src/ls.c (decode_switches): * src/mknod.c (main): * src/ptx.c (main): * src/shuf.c (main): * src/sort.c (specify_nmerge, specify_nthreads): Reject numbers with suffixes. * src/md5sum.c (split_3): Simplify.

shuf: fix bug with ‘-r -n 0’

2019-10-21T20:20:35Z

‘shuf -r -n 0 file’ would mistakenly read from standard input. Problem reported by my student Jingnong Qu while reimplementing a shuf subset in Python as an exercise in UCLA Computer Science 35L: https://web.cs.ucla.edu/classes/fall19/cs35L/assign/assign3.html * NEWS: Mention the fix. Also, ASCIIfy a previous item. * src/shuf.c (main): Fix bug. * tests/misc/shuf.sh: Add a test case for the bug.
