2016-01-06stty: support [-]drain setting to control waiting for pending TxPádraig Brady
Instead of commit v8.24-132-g5171bef which only provides control to disable this behavior (with -I), provide the symmetrical "[-]drain" special setting. * src/stty.c (main): Parse the [-]drain setting instead of -I, and treat like a global option. (usage): Adjust accordingly. * tests/misc/stty.sh: Test "drain" with and without options. * NEWS: Mention the new feature.
2016-01-04stty: support -I, --immediate to not wait for pending transmissionPádraig Brady

This also supports lookups like `info coreutils readlink`, but note that only works with the standard info viewer, and not with pinfo for example.
2016-01-03doc: mention in more places that -D will create --target-directoryPádraig Brady
* src/install.c (usage): Mention this commonly required functionality in the -D option description. * doc/coreutils.texi (install invocation): Likewise for the --target-directory description.

2015-11-30doc: avoid confusing K argument in the man pages of head and tailBernhard Voelker
The character 'K' representing numeric user input can be confusing, especially in the context where it can be suffixed by the multipliers K, M, G, etc. Use NUM instead. * doc/coreutils.texi (head invocation): Replace @var{k} by @var{num}. Also change @var{count} in the paragraph about the obsolete option syntax. (tail invocation): Likewise. Furthermore, adjust the option order to alphabetical sorting. * src/head.c (usage): s/K/NUM/ in as placeholder in the -c and -n options. Furthermore, print the actual DEFAULT_NUMBER instead of the hard-coded 10. * src/tail.c (usage): s/K/NUM/ in as placeholder in the -c and -n options. Add "[+]" to clarify that NUM may optionally be preceded by this sign. Remove the redundant explanation of the optional '+' prefix for NUM, as that is now clear from the option description above. Suggested by Dan Jacobson in http://bugs.gnu.org/22042
2015-11-25build: avoid makeinfo unless requiredPádraig Brady
* doc/local.mk (constants.texi): Avoid calling makeinfo unless the constants derived from tail and shred have changed. This avoids a dependence on makeinfo from patched sources, and avoids an expensive makeinfo call for developers.
2015-11-25doc: clarify descriptions for tr --squeeze-repeatsPádraig Brady
* doc/coreutils.texi (uniq invocation): Fix the description of problematic input to say "blank lines" rather than "two or more blank lines".

Also add "deleting" to the menu item. * src/tr.c (usage): Improve the -s summary to say it always operates on the last specified SET.
2015-11-25doc: provide an example for prefixing all tail output linesPádraig Brady
* doc/coreutils.texi (tail invocation): Provide an example using awk to convert tail ==> file <== headers to file: prefixes on each line. Suggested by Stephen Shirley.

For example: datagen | tee >(md5sum --tag) > >(sha256sum --tag) | sort * doc/coreutils.texi (tee invocation): Mention that -p is useful with pipes that may not consume all data. Add an example, similar to the one above. * THANKS.in: Add Jirka Hladky.
2015-11-04ls: default to --quoting=shell-escape for output to terminalPádraig Brady
* src/ls.c (decode_switches): Set "shell-escape" if isatty(). * doc/coreutils.texi (ls invocation): Update the defaults description. * NEWS: Mention the change in behavior. It should not have backwards compat issues, but mentioning here just in case.

2015-11-02doc: fix texinfo for short options taking a parameterPádraig Brady
* doc/coreutils.texi: (tail invocation): Add missing -s, along with the existing --sleep-interval description. (csplit invocation): s/--suffix/--suffix-format/. (head invocation): Use same variable (COUNT) for -n and --head-count. (seq invocation): Add opindex items for all options. (ptx invocation): Likewise. Fix typo s/--flac-truncation/--flag-truncation/. (touch invocation): State explicitly that -d takes a parameter, which also indicates that an '=' is not to be used for the short option syntax. (ls invocation): Likewise for the -w option. Fixes http://bugs.gnu.org/21809
2015-10-28doc: clarify iso-8601 formats used by ls and duPádraig Brady
* doc/coreutils.texi (du invocation): Remove 'like' from mentions of ISO-8601 as the components are individually conformant. (ls invocation): Likewise, except for --time-style=iso for recent files, where the MM-DD component is not a valid ISO-8601 timestamp.
2015-10-27date: use extended format timezone for --iso-8601Pádraig Brady
* src/date.c (main): Use %:z rather than %z with --iso-8601 as the standard states to consistently use extended format. Note either format can be parsed by date. * tests/misc/date.pl: Adjust accordingly. * doc/coreutils.texi (du invocation): Clarify that "iso" time styles are only similar to ISO-8601. (ls invocation): Likewise. (date invocation): Adjust the comment stating that only --rfc-3339 output can be parsed by date(1). * NEWS: Mention the change in behavior. Reported at http://bugs.debian.org/799479
2015-10-21ls: allow -w0 to mean no limit on line lengthPádraig Brady
* src/ls.c (print_with_separator): Renamed from print_with_commas, and parameterized to accept the separator to print. Also fix an edge case where '\n' not printed when the POS variable overflows SIZE_MAX. (print_current_files): Degenerate -x and -C to using the cheaper print_with_separator() in the -w0 case. * doc/coreutils.texi (ls invocation): Document the new feature. * tests/ls/w-option.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/21325
2015-10-19factor: remove unreachable SQUFOF code at compile timePádraig Brady
It was a little confusing as to whether the SQUFOF algorithm was enabled, and in fact there were no options available to enable it. Therefore clarify the 3 configurable behaviors for the code to 3 defines at the top of the program, and only include the SQUFOF code if enabled at compile time. $ size src/factor-before text data bss 93997 1412 2504 $ size src/factor-after text data bss 87885 1404 2504 * src/factor.c: Only include the SQUFOF factor code when enabled via the USE_SQUFOF define. * doc/coreutils.texi (factor invocation): Update note about factor limits, as we can factor 128 bit numbers without GMP.
2015-10-16doc: remove obsolete performance commentPaul Eggert
sha512sum can be faster than sha256sum. E.g., ‘dd if=/dev/zero bs=1024k count=1024 | time sha256sum’ reports 8.16 user CPU seconds on my host, whereas sha512sum consumes 5.45 seconds (Fedora x86-64 on an AMD Phenom II X4 910e). Although sha512sum is still considerably slower on x86, a good chunk of uses are on 64-bit hosts and anyway there’s little point to scaring people away from sha512sum nowadays. * doc/coreutils.texi (sha2 utilities): Remove obsolete comment.
2015-09-17shred: don’t document -NUMBER optionPaul Eggert
The -NUMBER option was removed from ‘shred’ in 1999, but the manual wasn’t updated to match. Problem reported by Nick Rose in: http://bugs.gnu.org/21502 * doc/coreutils.texi (shred invocation): Remove documentation for -NUMBER option.

2015-08-27doc: clarify where ambiguous if short options take no paramPádraig Brady
* doc/coreutils.texi (split invocation): Clarify that -d takes no param. (uniq invocation): Likewise for -D. (shred invocation): Likewise for -u. (tee invocation): Likewise for -p.
2015-07-22doc: discourage use of uname -i and -p optionsPádraig Brady
* src/uname.c (usage): State that the non POSIX -i and -p options are non-portable. * doc/coreutils.texi (uname invocation): Mention the discrepancies even across GNU/Linux distros, and that the results should be used as informational only, rather than impacting any logic decisions. Fixes http://bugs.gnu.org/13001
2015-07-15tests: avoid test warning with perl >= 5.22Peter Bray
* doc/local.mk (sc-lower-case-var): Escape a literal left curly bracket, needed with perl >= 5.22 Fixes http://bugs.gnu.org/21060
2015-06-22doc: list numfmt in the main menu with "Numeric operations"Pádraig Brady
* doc/coreutils.texi (main menu): Add numfmt.
2015-06-21numfmt: support user specified output precisionPádraig Brady
* src/numfmt.c (usage): Update the --format description to indicate precision is allowed. (parse_format_string): Parse a precision specification like the standard printf does. (double_to_human): Honor the precision in --to mode. * tests/misc/numfmt.pl: New tests. * doc/coreutils.texi (numfmt invocation): Mention the new feature. * NEWS: Likewise.
2015-06-19numfmt: implement support for field rangesDylan Cali
* src/numfmt.c: Replace field handling code with logic that understands field range specifiers. Instead of processing a single field and printing line prefix/suffix around it, process each field in the line checking whether it has been included for conversion. If so convert and print, otherwise just print the unaltered field. (extract_fields): Removed. (skip_fields): Removed. (process_line): Gutted and heavily reworked. (process_suffixed_number): FIELD is now passed as an arg instead of using a global. (parse_field_arg): New function that parses field range specifiers. (next_field): New function that returns pointers to the next field in a line. (process_field): New function that wraps the field conversion logic (include_field): New function that checks whether a field should be converted (compare_field): New function used for field value comparisons in a gl_list. (free_field): New function used for freeing field values in a gl_list. Global variable FIELD removed. New global variable all_fields indicates whether all fields should be processed. New global variable all_fields_after stores the first field of a N- style range. New global variable all_fields_before stores the last field of a -M style range. New global variable field_list stores explicitly specified fields to process (N N,M or N-M style specifiers). (usage): Document newly supported field range specifiers. * bootstrap.conf: Include xlist and linked-list modules. numfmt now uses the gl_linked_list implementation to store the field ranges. * tests/misc/numfmt.pl: Add tests for 'cut style' field ranges. Adjust existing tests as partial output can occur before an error Remove test for the 'invalid' field -5.. this is now a valid range. * gnulib: update to avoid compiler warnings in linked-list. * NEWS: Mention the new feature.
