2016-10-16all: use die() rather than error(EXIT_FAILURE)Pádraig Brady
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, ...);
2016-01-13wc: avoid ambiguous output with '\n' in file namesPádraig Brady
* src/wc.c (write_counts): Shell escape the file name if it contains '\n' so only a single line per file is output. * tests/misc/wc-files0.sh: Add a test case. * NEWS: Mention the improvement.
2016-01-01maint: update all copyright year number rangesPádraig Brady
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.
2015-12-14maint: remove form feed characters from sourcesPádraig Brady
These are no longer useful and can impact viewing patches in some mail programs for example. * src/cksum.c: Remove ^L characters. * src/comm.c: Likewise. * src/kill.c Likewise. * src/ln.c Likewise. * src/nl.c Likewise. * src/pr.c Likewise. * src/ptx.c Likewise. * src/split.c Likewise. * src/tr.c Likewise. * src/tsort.c Likewise. * src/uniq.c Likewise. * src/wc.c Likewise. * cfg.mk (sc_prohibit-form-feed): A new syntax check.
2015-11-04all: avoid quoting file names when possiblePádraig Brady
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.
2015-11-04all: replace most uses of quotearg_colon() with quote()Pádraig Brady
Related to commit v8.24-61-g6796698 this provides more consistent quoting, as quotearg_colon() defaults to "literal" quoting by default, while quote() provides appropriate quoting for diagnostics by default. * gl/modules/randread: Depend on quote module rather than quotearg. * gl/lib/randread.c: Used quote() not quotearg_colon(). * src/: Likewise. * src/shred.c: Likewise. Also avoid unnecessary quoting introducing overhead when wiping names. * cfg.mk: Relax the matching expression to allow "qname" variables as used in shred.c to satisfy the check. * tests/: Adjust accordingly.
2015-10-27all: quote string arguments in error messagesPádraig Brady
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.
2015-07-02wc: fix reading of /proc files on aarch64Pádraig Brady
tests/misc/wc-proc.sh fails when the page size is 64K * src/wc.c (wc): The lseek adjustment should be based on st_blksize, rather than on the internal buffer size. This is significant on aarch64 where st_blksize in /proc is the 64K (the page size) and thus larger than the internal buffer. * src/split.c (main): Even though the similar processing is done on the internal buffer size, that's based on st_blksize and so fine in this regard. Add an assert to enforce this. Avoid this path for the undocumented ---io-blksize option.
2015-05-13doc: clarify the operation of wc -LAssaf Gordon
* src/wc.c (usage): State that it calculates display width. * doc/coreutils.texi (wc invocation): Detail the distinct items used to determine the display width.
2015-04-30doc: standardize messages about the '-' stdin FILEPádraig Brady
* src/system.h (emit_stdin_note): A new function, refactoring the usage note about the '-' FILE implying stdin. * src/base64.c (usage): Use the new function to emit the note in a standard location and with standard separation. * src/cat.c (usage): Likewise. * src/csplit.c (usage): Likewise. * src/cut.c (usage): Likewise. * src/expand.c (usage): Likewise. * src/fmt.c (usage): Likewise. * src/head.c (usage): Likewise. * src/md5sum.c (usage): Likewise. * src/nl.c (usage): Likewise. * src/od.c (usage): Likewise. * src/paste.c (usage): Likewise. * src/pr.c (usage): Likewise. * src/ptx.c (usage): Likewise. * src/shred.c (usage): Likewise. * src/shuf.c (usage): Likewise. * src/sort.c (usage): Likewise. * src/sum.c (usage): Likewise. * src/tac.c (usage): Likewise. * src/tail.c (usage): Likewise. * src/tsort.c (usage): Likewise. * src/unexpand.c (usage): Likewise. * src/wc.c (usage): Likewise. * src/join.c (usage): Adjust the separation used for the message referring to FILE1 or FILE2 as stdin. * src/comm.c (usage): Add a message using the same wording (translation) as used in join. * src/split.c (usage): Reword to using FILE rather than INPUT, allowing use of emit_stdin_note(). Also remove the mention of "fixed-size" pieces as this isn't now always the case. Fixes http://pad.lv/1450179
2015-04-22maint: avoid -Werror=strict-overflow warnings with GCC 5Pádraig Brady
All warnings were of the form: "assuming signed overflow does not occur when simplifying conditional to constant [-Werror=strict-overflow]" * src/dd.c (cache_round): Use an appropriately sized unsigned type, to avoid possibility of undefined signed overflow. * src/mknod.c (main): Likewise. * src/pr.c (pad_down): Likewise. * src/wc.c (main): Likewise. * src/tail.c (main): Assert that argc >= 0 thus allowing the compiler to assume without implication that argc - optind is positive.
2015-03-24wc: use a more adaptive wc -l implementationPádraig Brady
* src/wc.c (wc): Allow any block to select the count implementation, rather than just using the first 10 lines. This also simplifies the code from 3 loops to 2.
2015-03-20wc: speedup counting of short linesKristoffer Brånemyr
Using a test file generated with: yes | head -n100M > 2x100M.txt before> time wc -l 2x100M.txt real 0.842s user 0.810s sys 0.033s after> time wc -l 2x100M.txt real 0.142s user 0.111s sys 0.031s * src/wc.c (wc): Split the loop that deals with -l into 3. The first is used at the start of the input to determine if the average line length is < 15, and if so the second loop is used to look for '\n' internally to wc. For longer lines, memchr is used as before to take advantage of system specific optimizations which any outweigh function call overhead. Note the first 2 loops could be combined, though in testing, GCC 4.9.2 at least, wasn't sophisticated enough to separate the loops based on the "check_len" invariant. Note also __builtin_memchr() isn't significant here as GCC currently only applies constant folding with that. * NEWS: Mention the improvement.
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.
2014-10-07wc: don't miscount /sys and similar file systemsPaul Eggert

(elide_tail_bytes_pipe, elide_tail_lines_pipe): New arg CURRENT_POS. All uses changed. (elide_tail_bytes_file, elide_tail_lines_file): New arg ST and remove arg SIZE. All uses changed. * src/head.c (elide_tail_bytes_file): * src/od.c (skip): Avoid optimization for /sys files, where st_size is bogus and st_size == st_blksize. Don't report error at EOF when not optimizing. * src/head.c, src/od.c, src/tail.c: Include "stat-size.h". * src/split.c (input_file_size): New function. (bytes_split, lines_chunk_split, bytes_chunk_extract): New arg INITIAL_READ. All uses changed. Use it to double-check st_size. * src/tac.c (tac_seekable): New arg FILE_POS. All uses changed. (copy_to_temp): Return size of temp file. All uses changed. * src/tac.c (tac_seekable): * src/tail.c (tail_bytes): * src/wc.c (wc): Don't trust st_size; double-check by reading. * src/wc.c (wc): New arg CURRENT_POS.

2014-09-19doc: output correct --help references with --program-prefixPádraig Brady
* 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.
2014-09-08maint: prefer 'return status;' to 'exit (status);' in 'main'Paul Eggert

2011-07-13doc: note the order in which wc counts are printedBenoît Knecht
This information has already been added to the Texinfo manual, but was missing from the --help output. * src/wc.c (usage): As above, for --help. Reported by Vincent Lefevre in http://bugs.debian.org/395430.
2011-07-02maint: use "const" and "pure" function attributes where possibleJim Meyering
* configure.ac (WARN_CFLAGS): Add -Wsuggest-attribute=const, -Wsuggest-attribute=pure and -Wsuggest-attribute=noreturn. (GNULIB_WARN_CFLAGS): But do not add them here... yet. * src/chown-core.h (chopt_free, uid_to_name): Add function attribute(s). * src/copy.c (is_ancestor, valid_options): Likewise. * src/copy.h (chown_failure_ok): Likewise. * src/dd.c (operand_matches, operand_is): Likewise. * src/df.c (selected_fstype, excluded_fstype): Likewise. * src/expr.c (null looks_like_integer): Likewise. * src/md5sum.c (hex_digits): Likewise. * src/od.c (get_lcm): Likewise. * src/pathchk.c (component_start, component_len): Likewise. * src/pinky.c (count_ampersands): Likewise. * src/pr.c (cols_ready_to_print): Likewise. * src/ptx.c (search_table): Likewise. * src/sort.c (find_unit_order): Likewise. * src/stty.c (mode_type_flag, string_to_baud, baud_to_value): Likewise. * src/system.h (gcd, lcm): Likewise. * src/tr.c (is_char_class_member, look_up_char_class): Likewise.

2011-05-08maint: remove -Wmissing-field-initializers workaroundsPádraig Brady
* configure.ac: Rather than disabling -Wmissing-field-initializers, use the fact that gnulib now disables it automatically when required (on versions of GCC older than 4.7). * src/system.h: Remove the no longer needed DECLARE_ZEROED_AGGREGATE. * src/ls.c: Likewise. * src/pathchk.c: Likewise. * src/shred.c: Likewise. * src/stty.c: Likewise. * src/wc.c: Likewise.
2011-03-03du: don't infloop for --files0-from=DIRJim Meyering
* src/du.c (main): Fail on AI_ERR_READ error, rather than merely diagnosing and continuing. Based on a patch by Stefan Vargyas. Also move the handling of AI_ERR_EOF into the case stmt. Do not report ferror/fclose(stdin) failure when we've already diagnosed e.g., failure to read the DIR, above. Bug introduced by 2008-11-24 commit 031e2fb5, "du: read and process --files0-from= input a name at a time,". * src/wc.c: Handle read failure as with du: do not exit immediately, but rather go on to print any total and to clean-up. As above, move the handling of AI_ERR_EOF into the case stmt. * tests/du/files0-from-dir: New file, to test both du and wc. * tests/Makefile.am (TESTS): Add it. * NEWS (Bug fixes): Mention it.
2011-03-03wc: avoid NULL dereference on out-of-memory errorJim Meyering
* src/wc.c (main): Diagnose failed argv_iter_init_* failure, rather than falling through and dereferencing NULL. Bug introduced by 2008-11-25 commit c2e56e0d, "wc: read and process --files0-from= input a name at a time,". * NEWS (Bug fixes): Mention it.

2010-12-19wc: fix a possible hang with --files0-fromPádraig Brady
* src/wc.c (main): exit when we get a read error on the --files0-from file, rather than retrying and spinning the CPU
2010-07-22provide POSIX_FADV_SEQUENTIAL hint to appropriate utilsPádraig Brady
Following on from commit dae35bac, 01-03-2010, "sort: inform the system about our input access pattern" apply the same hint to all appropriate utils. This currently gives around a 5% speedup for reading large files from fast flash devices on GNU/Linux. * src/base64.c: Call fadvise (..., FADVISE_SEQUENTIAL); * src/cat.c: Likewise. * src/cksum.c: Likewise. * src/comm.c: Likewise. * src/cut.c: Likewise. * src/expand.c: Likewise. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/join.c: Likewise. * src/md5sum.c: Likewise. * src/nl.c: Likewise. * src/paste.c: Likewise. * src/pr.c: Likewise. * src/ptx.c: Likewise. * src/shuf.c: Likewise. * src/sum.c: Likewise. * src/tee.c: Likewise. * src/tr.c: Likewise. * src/tsort.c: Likewise. * src/unexpand.c: Likewise. * src/uniq.c: Likewise. * src/wc.c: Likewise, unless we don't actually read().

2009-12-23wc: line-buffer the printed countsPádraig Brady
* src/wc.c (main): Set stdout to line buffered mode to ensure parallel running instances don't intersperse their output. This adds 6.5% to the run time in the worst case of many zero length files, but has neglible impact for standard sized files. * tests/misc/wc-parallel: New test for atomic output. * tests/Makefile.am: Reference it. * NEWS: Mention the fix This is similar to commit 710fe413, 20-10-2009, "md5sum, sha*sum, sum: line-buffer the printed checksums"
2009-09-23maint: Use logical rather than bitwise operators on boolsPádraig Brady
This is because bitwise operators are: - confusing and inconsistent in a boolean context - non short circuiting - brittle in C89 where bool can be an int (so > 1)
2009-09-21doc: mention the texinfo documentation in --helpPádraig Brady
* src/system.h: Rename emit_bug_reporting_address() to emit_ancillary_info() and update it to not print the translation project address in en_* locales, and _do_ print it in the 'C' (and other) locales so that it's included in the default man page. Also mention how to invoke the texinfo documentation for each command. Also move the "hard-locale.h" include to the 8 files that now use it. * man/help2man: Strip the newly added texinfo reference from the --help output as a more verbose version is already added by help2man. Suggestion from C de-Avillez

2008-12-02wc: read and process --files0-from= input a name at a time,Jim Meyering
when the file name list is not too large. Before, wc would always read the entire file name list into memory and *then* process each file name. wc does read the list into memory when the list is known not to be too large; this is done in order to be able to align the output numbers, as it does with arguments specified on the command-line * src/wc.c: Include "argv-iter.h". (main): Rewrite to use argv-iter when the input file name list is known to be too large. * NEWS (Bug fixes): Mention it.

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".
