2025-09-17maint: STREQ → streqPaul Eggert1-2/+2
Use new Gnulib streq function instead of rolling our own macro. * bootstrap.conf (gnulib_modules): Add stringeq. * src/rm.c (main): Don’t assume streq is a macro that expands to (...), as it is now a function. * src/system.h: * tests/df/no-mtab-status.sh, tests/df/skip-duplicates.sh: (STREQ): Remove. All uses replaced by streq.
2025-01-01maint: update all copyright year number rangesPádraig Brady1-1/+1
Update to latest gnulib with new copyright year. Run "make update-copyright" and then... * gnulib: Update included in this commit as copyright years are the only change from the previous gnulib commit. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Likewise. * tests/sample-test: Adjust to use the single most recent year.
2024-12-30maint: ISDIGIT → c_isdigitPaul Eggert1-1/+2
* gl/lib/strnumcmp-in.h (ISDIGIT): * src/system.h (ISDIGIT): Remove. All uses replaced by c_isdigit, with appropriate inclusions of c-ctype.h. This is more regular, and is more portable to existing (but unlikely) platforms where INT_MAX == UINT_MAX.
2024-01-01maint: update all copyright year number rangesPádraig Brady1-1/+1
Update to latest gnulib with new copyright year. Run "make update-copyright" and then... * gnulib: Update included in this commit as copyright years are the only change from the previous gnulib commit. * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Manually update copyright year, until we fully sync with gnulib at a later stage. * tests/sample-test: Adjust to use the single most recent year.
2023-09-23expr: use mcelPaul Eggert1-59/+47
The mcel API is simpler and corresponds more closely to how Emacs etc. behave when the input has encoding errors, since it treats each encoding-error byte separately. * bootstrap.conf (gnulib_modules): Add mcel. * src/expr.c: Include mcel.h instead of mbuiter.h. (mbs_logical_cspn, mbs_logical_substr, mbs_offset_to_chars): Use mcel API. (mbs_logical_substr): Use ximemdup0 so as not to waste memory in the result, fixing a FIXME.
2023-07-31dircolors,du,expr: prefer signed typesPaul Eggert1-4/+3
* src/dircolors.c (dc_parse_stream): * src/du.c (max_depth, main): * src/expr.c (main): Prefer signed types.
2023-07-01maint: go back to using ‘error’Paul Eggert1-23/+21
Now that Gnulib’s ‘error’ module does proper static checking for not returning, we need no longer use the ‘die’ macro. This makes code easier to read for people that are used to ‘error’. * cfg.mk (error_fns, exclude_file_name_regexp): Remove ‘die’. (sc_die_EXIT_FAILURE): Remove. * src/die.h: Remove. All includes removed. All calls to ‘die’ changed back to calls to ‘error’. * src/install.c (get_ids): Use quoteaf (problem found with make syntax-check). * src/system.h: Include error.h, since some of our macros call ‘error’. Stop including error.h elsewhere.
2023-07-01maint: improve static and dynamic checkingPaul Eggert1-5/+5
This modernizes the source code somewhat, to take advantage of advances in GCC over the years, and Gnulib’s ‘assure’ module. Include assure.h in files that now need it. Do not include assert.h directly; it’s no longer needed. * bootstrap.conf (gnulib_modules): Add ‘assure’. * gl/lib/randread.c (randread_error): * src/chmod.c (describe_change): * src/chown-core.c (describe_change): * src/cp.c (decode_preserve_arg): * src/head.c (diagnose_copy_fd_failure): * src/ls.c (parse_ls_color): * src/od.c (decode_one_format): * src/split.c (main): * src/test.c (binary_operator, posixtest): Prefer affirm to abort, since it has better diagnostics in the normal case and better performance with -DNDEBUG. * gl/lib/xdectoint.c, src/die.h: Include stddef.h, for unreachable. * gl/lib/xdectoint.c: Do not include verify.h; no longer needed. * gl/lib/xdectoint.c (__xnumtoint): * src/die.h (die): Prefer C23 unreachable () to assume (false). * gl/lib/xfts.c (xfts_open): * src/basenc.c (base32hex_encode): * src/copy.c (abandon_move, copy_internal, valid_options): * src/cut.c (cut_fields): * src/df.c (alloc_field, decode_output_arg, get_dev): * src/du.c (process_file, main): * src/echo.c (usage): * src/factor.c (udiv_qrnnd, mod2, gcd2_odd, factor_insert_large) (mulredc2, factor_using_pollard_rho, isqrt2, div_smallq) (factor_using_squfof): * src/iopoll.c (iopoll_internal, fwrite_wait): * src/join.c (add_field): * src/ls.c (dev_ino_pop, main, gobble_file, sort_files): * src/mv.c (do_move): * src/od.c (decode_format_string, read_block, dump, main): * src/remove.c (rm): * src/rm.c (main): * src/sort.c (stream_open): * src/split.c (next_file_name, lines_chunk_split): * src/stdbuf.c (main): * src/stty.c (set_speed): * src/tac-pipe.c (line_ptr_decrement, line_ptr_increment): * src/touch.c (touch): * src/tr.c (find_bracketed_repeat, get_next) (validate_case_classes, get_spec_stats, string2_extend, main): * src/tsort.c (search_item, tsort): * src/wc.c (main): Prefer affirm to assert, as it allows for better static checking when compiling with -DNDEBUG. * src/chown-core.c (change_file_owner): * src/df.c (get_field_list): * src/expr.c (printv, null, tostring, toarith, eval2): * src/ls.c (time_type_to_statx, calc_req_mask, get_funky_string) (print_long_format): * src/numfmt.c (simple_strtod_fatal): * src/od.c (decode_one_format): * src/stty.c (mode_type_flag): * src/tail.c (xlseek): * src/tr.c (is_char_class_member, get_next, get_spec_stats) (string2_extend): Prefer unreachable () to abort () or assert (false) when merely pacifying the compiler, e.g., in a switch statement on an enum where all cases are covered. * src/copy.c (valid_options): Now returns void; the bool was useless. Caller no longer needs to assert. * src/csplit.c (find_line): * src/expand-common.c (next_file): * src/shred.c (incname): * src/sort.c (main): * src/tr.c (append_normal_char, append_range, append_char_class) (append_repeated_char, append_equiv_class): * src/tsort.c (search_item): Omit assert, since the hardware will check for us. * src/df.c (header_mode): Now the enum type it should have been. * src/du.c (process_file): * src/ls.c (assert_matching_dev_ino): * src/tail.c (valid_file_spec): * src/tr.c (validate_case_classes): Mark defns with MAYBE_UNUSED if they’re not used when -DNDEBUG. * src/factor.c (prime_p, prime2_p, mp_prime_p): Now ATTRIBUTE_PURE. Prefer affirm to error+abort. No need to translate this diagnostic. * src/fmt.c (get_paragraph): * src/stty.c (display_changed, display_all, sane_mode): * src/who.c (idle_string): Prefer assume to assert, since the goal is merely pacification and assert doesn’t pacify anyway if -DNDEBUG is used. * src/join.c (decode_field_spec): Omit unreachable abort. * src/ls.c (assert_matching_dev_ino, main): * src/tr.c (get_next): Prefer assure to assert, since the check is relatively expensive and won’t help static analysis. * src/ls.c (main): Prefer static_assert to assert of a constant expression. (format_inode): Redo to make it clear that buflen doesn’t matter, and that buf must have a certain number of bytes. All callers changed. This pacifies -Wformat-overflow. * src/od.c (decode_one_format): Omit an assert that tested for obviously undefined behavior, as the compiler could optimize it away anyway. * src/od.c (decode_one_format, decode_format_string): Prefer ATTRIBUTE_NONNULL to runtime checking. * src/stat.c: Do not include <stddef.h> since system.h does that now. * src/sync.c (sync_arg): Prefer unreachable () to assert (true), which was a typo. * src/system.h: Include stddef.h, for unreachable. * src/tail.c (xlseek): Simplify by relying on ‘error’ to exit.
2023-06-29maint: prefer C23-style nullptrPaul Eggert1-9/+9
* bootstrap.conf (gnulib_modules): Add nullptr. In code, prefer nullptr to NULL where either will do.
2023-01-01maint: update all copyright year number rangesPádraig Brady1-1/+1
Update to latest gnulib with new copyright year. Run "make update-copyright" and then... * tests/init.sh: Sync with gnulib to pick up copyright year. * bootstrap: Manually update copyright year, until we fully sync with gnulib at a later stage. * tests/sample-test: Adjust to use the single most recent year.
2022-09-15maint: prefer static_assert to verifyPaul Eggert1-1/+1
* bootstrap.conf: Add assert-h. * gl/lib/randperm.c: Do not include verify.h. * gl/lib/randperm.c, src/basenc.c, src/dd.c, src/digest.c: * src/dircolors.c, src/expr.c, src/factor.c, src/ls.c, src/numfmt.c: * src/od.c, src/seq.c, src/shred.c, src/sort.c, src/stat.c: Prefer C23’s static_assert to nonstandard verify. * gl/modules/randperm (Depends-on): Add assert-h.
2022-01-31expr: lint cleanup, and introducing main_exitPaul Eggert1-2/+2
This introduces a new macro main_exit, which is useful for pacifying gcc -fsanitizer=lint and in some cases means we can remove some ‘IF_LINT’ and ‘ifdef lint’ code. * src/expr.c (main): Use main_exit, not return. (docolon): Omit an IF_LINT that GCC no longer needs. * src/system.h (main_exit): New macro.
2022-01-02maint: update all copyright year number rangesPádraig Brady1-1/+1

2021-12-18maint: use GNU style for spacingPaul Eggert1-2/+2
2021-10-31maint: prefer attribute.h in .c filesPaul Eggert1-2/+4
This will help us make the transition to C2x, where some attributes must come at the start of function decls. Leave the attributes alone in .h files for now, as the Gnulib tradition is to not expose attribute.h to users. * bootstrap.conf (gnulib_modules): Add ‘attribute’. * gl/lib/randperm.c, src/make-prime-list.c, src/system.h: Include attribute.h. * gl/lib/strnumcmp.c (strnumcmp): Remove _GL_ATTRIBUTE_PURE here, as this belongs in the .h file. * gl/lib/strnumcmp.h (strnumcmp): Add _GL_ATTRIBUTE_PURE here. * src/sort.c (human_numcompare, numcompare): Now ATTRIBUTE_PURE; discovered due to strnumcmp.h change. * gl/lib/randperm.c, src/copy.c, src/dd.c, src/df.c, src/digest.c: * src/env.c, src/expr.c, src/factor.c, src/ls.c: * src/make-prime-list.c, src/numfmt.c, src/od.c, src/pathchk.c: * src/pinky.c, src/pr.c, src/ptx.c, src/realpath.c, src/relpath.c: * src/seq.c, src/sort.c, src/stat.c, src/stty.c, src/system.h: * src/tr.c, src/uniq.c, src/wc.c: In .c files, crefer ATTRIBUTE_CONST to _GL_ATTRIBUTE_CONST, and similarly for ATTRIBUTE_FORMAT and ATTRIBUTE_PURE. * src/system.h (FALLTHROUGH): Remove; attribute.h defines it.
2021-06-26maint: while (1) → while (true)Paul Eggert1-6/+6
2021-04-11maint: use "char const *" rather than "const char *"Pádraig Brady1-4/+4
* cfg.mk (sc_prohibit-const-char): Add a new syntax-check to enforce this style. * *.[ch]: sed -i 's/const char \*/char const */g'
2021-01-26expr: fix bug with unmatched \(...\)Paul Eggert1-2/+7
Problem reported by Qiuhao Li. * NEWS: Mention this. * doc/coreutils.texi (String expressions): Document the correct behavior, which POSIX requires. * src/expr.c (docolon): Treat unmatched \(...\) as empty. * tests/misc/expr.pl: New test.

2020-11-27maint: fix typo, characteres -> charactersTim Gates1-1/+1
* src/expr.c: Fix typo in comment.
2020-07-07maint: use Gnulib libgmp modulePaul Eggert1-109/+2
This lets use assume multiple-precision arithmetic on all platforms, simplifying the code. * bootstrap.conf (gnulib_modules): Add libgmp. * configure.ac: Don’t call cu_GMP, as this is now done by Gnulib. * m4/gmp.m4: Remove. * src/expr.c, src/factor.c: Use gmp.h unconditionally. * src/factor.c: Use the simpler ‘#ifndef mpz_inits’ to determine whether there is an mpz_inits macro.

2019-10-22all: improve parsing of numeric argumentsPaul Eggert1-1/+1
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.

2018-06-24maint: fix -Werror=suggest-attribute=malloc in expr.cCarlos Santos1-1/+1
Add attribute 'malloc' to mpz_get_str to prevent the following on GCC 8.1.1 src/expr.c:117:1: error: function might be candidate for attribute 'malloc' if it is known to return normally [-Werror=suggest-attribute=malloc] mpz_get_str (char const *str, int base, mpz_t z) ^~~~~~~~~~~ cc1: all warnings being treated as errors * src/expr.c (mpz_get_str): Add _GL_ATTRIBUTE_MALLOC.

2017-09-19expr: add detailed syntax error messagesAssaf Gordon1-13/+23
Show offending argument instead of a generic 'syntax error' message. Suggested by Bernhard Voelker in https://bugs.gnu.org/28461#13 . * src/expr.c (syntax_error): Remove. (required_more_args): New function. (eval7, main): Replace syntax_error call with detailed die message. * tests/misc/expr.pl: Add tests for new messages.
2017-09-19all: prefer HTTPS in URLsPaul Eggert1-1/+1
2017-08-30expr: fix a recently introduced memory leakKamil Dudka1-0/+1
* src/expr.c (eval6): Free memory allocated by mbs_logical_substr(). Introduced in v8.27-47-ga9f2be5. Detected by Coverity Analysis: Error: RESOURCE_LEAK: src/expr.c:851: leaked_storage: Variable "s" going out of scope leaks the storage it points to. 849| char *s = mbs_logical_substr (l->u.s, pos, len); 850| v = str_value (s); 851|-> } 852| freev (l); 853| freev (i1);
2017-06-28expr: add multibyte supportAssaf Gordon1-18/+156
Discussed in https://bugs.gnu.org/26779 . * NEWS: Mention the improvement. * bootstrap.conf: Add gnulib modules mbslen,mbschr. * src/expr.c (mbs_logical_substr): New function to return a substring based on logical character positions (instead of bytes). (mbs_logical_cspn): Similar to strcspn/mbscspn, but returns number of logical characters instead of byte offset. (mbs_offset_to_chars): New function to return number of logical characters fitting in a given byte offset. (docolon): Report matched logical characters instead of bytes. (eval6): For length/substr/index operations, use logical characters instead of bytes by calling the above new functions. * tests/misc/expr.pl: Repeat all tests with non-C locale to detect any regressions. * tests/misc/expr-multibyte.pl: New tests with multibyte input. * tests/local.mk: Add new test file.

2016-10-16maint: we use die; remove now-unnecessary uses of abortJim Meyering1-1/+0
* src/expr.c (integer_overflow): Remove an abort-after-die. * src/paste.c (write_error): Likewise. * src/sort.c (badfieldspec): Likewise. * src/tr.c (string2_extend): Likewise. Also remove a few break statements, each after an abort.
2016-10-16all: use die() rather than error(EXIT_FAILURE)Pádraig Brady1-14/+15
die() has the advantage of being apparent to the compiler that it doesn't return, which will avoid warnings in some cases, and possibly generate better code. * cfg.mk (sc_die_EXIT_FAILURE): A new syntax check rule to catch any new uses of error (CONSTANT, ...);
2016-01-01maint: update all copyright year number rangesPádraig Brady1-1/+1
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.
2015-11-04all: avoid quoting file names when possiblePádraig Brady1-1/+0
Quote file names using the "shell-escape" or "shell-escape-always" methods, which quote as appropriate for most shells, and better support copy and paste of presented names. The "always" variant is used when the file name is embedded in an error message with surrounding spaces. * cfg.mk (sc_error_shell_quotes): A new syntax check rule to suggest quotef() where appropriate. (sc_error_shell_always_quotes): Likewise for quoteaf(). * src/system.h (quotef): A new define to apply shell quoting when needed. I.E. when shell character or ':' is present. (quoteaf): Likewise, but always quote. * src/*.c: Use quotef() and quoteaf() rather than quote() where appropriate. * tests/: Adjust accordingly.
2015-10-27all: quote string arguments in error messagesPádraig Brady1-2/+2
These strings are often file names or other user specified parameters, which can give confusing errors in the presence of unexpected characters for example. * cfg.mk (sc_error_quotes): A new syntax check rule. * src/*.c: Wrap error() string arguments with quote(). * tests/: Adjust accordingly. * NEWS: Mention the improvement.
2015-01-01maint: update all copyright year number rangesPádraig Brady1-1/+1
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.
2014-09-19doc: output correct --help references with --program-prefixPádraig Brady1-1/+1
* src/system.h (emit_ancillary_info): Take the invariant PROGRAM_NAME as a parameter, so that consistent references are made to online docs and texinfo nodes, when a --program-prefix is in place. Note the man pages don't need this fix as they're generated before the program prefix is used. * NEWS: Mention the improvements in references to online documentation.
