coreutils/bootstrap.conf, branch v9.0

tail: fix detection of closed stdout on macOS

2021-09-21T16:50:54Z

* bootstrap.conf: We only need poll on Linux and AIX where poll is not replaced. Also resinstate dependence on select so we can use it unconditionally. * src/tail.c (check_output_alive): Reinstate use of select() by default as poll was seen to be ineffective for this application on macOS. Fixes https://bugs.gnu.org/50714

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.

digest: add support for sm3

2021-09-15T19:44:18Z

Add message digest sm3, which uses the OSCCA SM3 secure hash (OSCCA GM/T 0004-2012 SM3) generic hash transformation. * bootstrap.conf: Add the sm3 module. * doc/coreutils.texi: Mention the cksum -a option. * src/digest.c: Provide support for --algorithm='sm3'. * tests/misc/sm3sum.pl: Add a new test (from Tianjia Zhang) * tests/local.mk: Reference the new test. * NEWS: Mention the new feature. Tested-by: Tianjia Zhang

tail: use poll, not select

2021-06-27T01:40:26Z

This fixes an unlikely stack out-of-bounds write reported by Stepan Broz via Kamil Dudka (Bug#49209). * bootstrap.conf (gnulib_modules): Replace select with poll. * src/tail.c: Do not include . [!_AIX]: Include poll.h. (check_output_alive) [!_AIX]: Use poll instead of select. (tail_forever_inotify): Likewise. Simplify logic, as there is no need for a ‘while (len <= evbuf_off)’ loop.

maint: bootstrap: remove reference to unused hash-pjw module

2021-05-28T20:10:46Z

* bootstrap.conf (gnulib_modules): Remove hash-pjw. No longer used.

env: simplify --split-string memory management

2021-03-30T04:44:58Z

* bootstrap.conf (gnulib_modules): Add idx. * src/env.c: Include idx.h, minmax.h. Prefer idx_t to ptrdiff_t when values are nonnegative. (valid_escape_sequence, escape_char, validate_split_str) (CHECK_START_NEW_ARG): Remove; no longer needed now that we validate as we go. (struct splitbuf): New type. (splitbuf_grow, splitbuf_append_byte, check_start_new_arg) (splitbuf_finishup): New functions. (build_argv): New arg ARGC. Validate and process in one go, using the new functions; this is simpler and more reliable than the old approach (as witness the recent bug). Avoid integer overflow in the unlikely case where the string contains more than INT_MAX arguments. (parse_split_string): Simplify by exploiting the new build_argv.

ptx: remove use of diacrit module

2021-03-21T21:01:15Z

The diacrit module is obsolete, and ptx’s use of it is obsolete too; it assumes an 8-bit locale (not that common these days) and that TeX cannot process the 8-bit characters (nowadays, it can). * NEWS, doc/coreutils.texi (Charset selection in ptx): Document this. * bootstrap.conf (gnulib_modules): Remove diacrit. * src/ptx.c: Do not include diacrit.h. (print_field, fix_output_parameters): Remove obsolete support for 8-bit diacritics.

build: update gnulib submodule to latest

2021-03-21T21:01:15Z

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.

cksum: use more efficient slice by 8 algorithm

2020-12-28T16:21:38Z

A 100MB file improves from 2.50s to 1.80s on a Sparc T5220 A 100MB file improves from 0.54s to 0.13s on an i3-2310M * bootstrap.conf: Explicitly depend on byteswap, since now used directly by coreutils. * src/cksum.c (cksum): Process in multiples of 8 bytes. (main): Adjust for generation of expanded crctab. * src/cksum.h: Split now larger crctab to separate header. * src/local.mk: Reference the new header. * NEWS: Mention the improvement.
