2015-08-22ls: allow -w18446744073709551616Paul Eggert
Problem reported by Beco in: http://bugs.gnu.org/21325 * src/ls.c (set_line_length): New function. (decode_switches): Use it to decode COLUMNS and -w.
2015-07-23build: fprintftime/nstrftime API changesPaul Eggert
* bootstrap.conf (gnulib_modules): Add time_rz, since the main source code now uses timezone_t. * src/date.c (batch_convert, main, show_date): * src/ls.c (align_nstrftime, long_time_expected_width) (print_long_format): * src/stat.c (human_time): Use timezone_t rather than boolean to specify which time zone is wanted. * src/ls.c (localtz): New static var. (main): Initialize it.
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
2015-07-15doc: improve man page for realpath -mPádraig Brady
* src/realpath.c (usage): Mention 'directory' in the --help output, so that ENOTDIR errors may be more easily investigated, by inspecting the man page. Reported at http://pad.lv/1474519
2015-07-15sync: fix build with separate $(LIB_FDATASYNC)Peter Bray
* src/local.mk: Link with $(LIB_FDATASYNC) needed on some Solaris 10 systems for example. Fixes http://bugs.gnu.org/21059
2015-07-09dircolors: add tmux entriesPádraig Brady
* src/dircolors.hin: tmux entries were added to ncurses in: http://ncurses.scripts.mit.edu/?p=ncurses.git;a=blobdiff;\ f=misc/terminfo.src;h=ce9bdc3b;hp=7e576ef1;hb=be512fa0;hpb=ee1bcda2
2015-07-07shred: fix pattern selection for certain iteration countsPádraig Brady

Fixes http://bugs.gnu.org/20998
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.
2015-07-01numfmt: increase precision on 32 bit FreeBSDPádraig Brady
* m4/jm-macros.m4 (HAVE_FPSETPREC): Define if needed. * src/numfmt.c (main): Call fpsetprec() if needed. Fixes large-15 and large-16 test failures on 32 bit FreeBSD.
2015-07-01factor: ensure atomic output through pipesPádraig Brady
The new tests/misc/factor-parallel.sh test was seen to fail on FreeBSD (derived) systems, which was due to split(1) --filter reading partial lines through pipes, as factor(1) was writing a little over PIPE_BUF each time. * src/factor.c (lbuf): A new structure to internally buffer lines. (lbuf_alloc): A new function to allocate enough at program start. (lbuf_putint): A new function to buffer a uintmax_t. (lbuf_flush): A new function to write directly to standard output. (lbuf_putc): A new function to buffer a character and if enough lines are buffered, then output complete lines <= PIPE_BUF, and continue to buffer the rest. (main): Call the internal buffer allocator, and register the final flush from the internal buffer at program exit.
2015-06-29maint: stdbuf.c: avoid the OS X putenv functionJim Meyering
* bootstrap.conf (gnulib_modules): Add setenv, to make this module dependency explicit; setenv is also used by split. * src/stdbuf.c (set_LD_PRELOAD) [__APPLE__]: Use the OS X setenv function, rather than putenv, per that documentation: https://developer.apple.com/\ library/mac/documentation/Darwin/Reference/ManPages/man3/putenv.3.html
2015-06-29build: numfmt.c: avoid a shadowing warningJim Meyering
* src/numfmt.c (parse_field_arg): Rename parameter s/optarg/arg/, to avoid shadowing getopt's global variable. Otherwise, building on OS X, with --enable-gcc-warnings, I saw this: In file included from src/numfmt.c:19:0: src/numfmt.c: In function 'parse_field_arg': ./lib/config.h:3109:25: error: declaration of 'rpl_optarg' shadows\ a global declaration [-Werror=shadow]
2015-06-29numfmt: fix printf argument orderAssaf Gordon
* src/numfmt.c (double_to_human): Fix the argument order passed to snprintf, which happened to work on amd64 with its separate va_arg storage area for floats¹, but would fail tests for example on i686. ¹ https://blog.nelhage.com/2010/10/amd64-and-va_arg/
2015-06-28maint: clarify df's use of device IDs from /proc/self/mountinfoPádraig Brady
* src/df.c (filter_mount_list): Clarify why we still stat even though devices IDs may already be available. Note using /proc/self/mountinfo is still an advantage to get filtered items with accurate device patchs in chroots and with bind mounts. I.E. on older setups with static /etc/mtab, df will now bypass that to get the more accuracte and dynamic info.
2015-06-26chroot: quote argument in error diagnosticPádraig Brady
* src/chroot.c (main): Quote the passed argument, to avoid confusing error messages.
2015-06-25maint: clarify integer operations in recent commitPádraig Brady
* src/factor.c (print_uintmaxes): Comment that the value of n_out doesn't matter on error, and add an explicit cast to avoid any future warnings. Suggested by Jim Meyering RE commit v8.23-229-g4d2d6c5
2015-06-25build: allow build to complete with -fsanitize=addressPádraig Brady
* src/make-prime-list.c (main): When building with the above option, avoid this build stopping error: "LeakSanitizer: detected memory leaks"
2015-06-24maint: avoid undefined behavior in qsort callPádraig Brady
GCC 5.1.1 -fsanitize=undefined with glibc 2.21 is returning: "runtime error: null pointer passed as argument 1, which is declared to never be null" * src/ptx.c (sort_found_occurs): Avoid the call with no entries.
2015-06-24factor: avoid interspersed lines for parallel runsPádraig Brady
* src/factor.c (n_out): A new global variable to track how much data has been written to stdout. (print_factors_single): Use n_out to determine whether to flush the current (and previous) lines. * tests/misc/factor-parallel.sh: Add a new test. * tests/local.mk: Reference the new test. * NEWS: Mention the bug fix.
2015-06-24seq: handle exponents more consistentlyPádraig Brady
src/seq.c (scan_arg): Set precision and width _after_ exponentiation. For example, this will make '1.1e1 12' and '11 1.2e1' equivalent. One can still set the precision by specifying extra precision on the start value, or more naturally with a precision on a step value. * tests/misc/seq-precision.sh: Add new cases.
2015-06-24seq: use consistent output format with hex integersPádraig Brady
* src/seq.c (scan_arg): Set precision to 0 for hex constants (while avoiding hex floats). This will use then use the fast path for these arguments. Note we also set the precision of inf to 0 here, which ensures we use consistent precision on output where possible. * tests/misc/seq-precision.sh: Add corresponding test cases.
2015-06-24seq: support inf last item more generally/efficientlyPádraig Brady
* src/seq.c (main): Call seq_fast for infinite last value. This implicitly avoids format conversion on the 999999 -> 1000000 transition. * src/seq.c (seq_fast): Generalize the buffer handling, and adjust to handle the "inf" last value specifics. * tests/misc/seq-precision.sh: A new test. * tests/local.mk: Reference the new test.
2015-06-22numfmt: don't hardcode floating point limitsPádraig Brady
* src/numfmt.c (MAX_UNSCALED_DIGITS): Set this to LDBL_DIG rather than hardcoding at 18 for better portability. * tests/misc/numfmt.pl: Restrict limit tests to supported platforms.
2015-06-22numfmt: handle leading zeros correctlyPádraig Brady
* src/numfmt.c (simple_strtod_int): Don't count leading zeros as significant digits. Also have leading zeros as optional for floating point numbers. * tests/misc/numfmt.pl: Add test cases. * NEWS: Mention the fix.
2015-06-22numfmt: avoid integer overflow when roundingPádraig Brady
Due to existing limits this is usually triggered with an increased precision. We also add further restrictions to the output of increased precision numbers. * src/numfmt.c (simple_round): Avoid intmax_t overflow. (simple_strtod_int): Count digits consistently for precision loss and overflow detection. (prepare_padded_number): Include the precision when excluding numbers to output, since the precision determines the ultimate values used in the rounding scheme in double_to_human(). * tests/misc/numfmt.pl: Add previously failing test cases. * NEWS: Mention the fix.
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.
2015-06-19doc: use correct units in df | numfmt examplePádraig Brady
* src/numfmt.c (usage): Don't scale output from df so that numfmt outputs the correct values.
2015-06-19numfmt: handle suffixes consistently with --{from,to}-unitPádraig Brady
* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes with the --from-unit and --to-unit options. Treat suffixes like is done with --from=auto, which for example will change the meaning of --to-unit=G to that of --to-unit=Gi. The suffix support was previously undocumented and it's better to avoid the traditional coreutils suffix handling in numfmt by default. * doc/coreutils.texi: Document the new behavior. Also fix a typo mentioning {from,to}=units=. * tests/misc/numfmt.pl: Adjust accordingly. * NEWS: Mention the change in behavior.
2015-06-09tail: display consistent diagnostics upon file replacementPádraig Brady
* src/tail.c (recheck): Display diagnostices for replaced files even with reused inodes which is a common case. * tests/tail-2/F-vs-missing.sh: Use correct diagnostic in comment. * tests/tail-2/F-vs-rename.sh: Likewise.
2015-06-09tail: display file headers correctly with inotifyPádraig Brady
* src/tail.c (tail_forever_inotify): Use the fspec pointer to distinguish previously output files, rather than a descriptor from the inotify event. That event descriptor was that of the parent directory when files were created or renamed etc. (check_fspec): Adjust for the new comparison. Also show the header when the file is truncated, since we show data in this case also. * tests/tail-2/F-headers.sh: A new test case. * tests/local.mk: Reference the new test. * NEWS: Mention the bug fix.
2015-06-06build: port to AIXPaul Eggert
Problems reported by Michael Felt, and and part of this fix taken from code suggested by Pádraig Brady in: http://bugs.gnu.org/20733#112 * configure.ac (stdbuf_supported): Check for warnings, and for -fPIC and -shared, for AIX. * src/stat.c (STRUCT_STATVFS): Define to struct statvfs64 if STATFS is statvfs64. * src/sync.c (sync_arg) [_AIX]: Open in write mode, since AIX fsync doesn't work on read-only file descriptors. * tests/misc/wc-parallel.sh: Skip test if xargs -P does not work.
2015-06-04build: port single_binary_prog to POSIX shellPaul Eggert
Problem reported privately by Michael Felt. * Makefile.am (install-exec-hook): * src/local.mk (src/coreutils_symlinks, src/coreutils_shebangs) (clean-local): Port to POSIX shell, which doesn't allow 'for i in ; do ...'.
2015-05-30maint: avoid new coverity warningsPádraig Brady
* src/sync.c (sync_arg): Initialise variable to avoid unitialized access if assert is disabled. * src/head.c (elide_tail_bytes_file): Support this function with ---presume-input-pipe and larger files, which regressed with commit v8.23-47-g2662702. (elide_tail_lines_file): Likewise. * src/dd.c (dd_copy): Explicitly don't try to ftruncate() upon failure to lseek() (the existing check against st_size was already protecting that). * src/factor.c (factor_using_squfof): Assert (only when linting due to performance) to avoid the implication of divide by zero. * src/od.c (read_block): Remove dead code. * src/tac.c (tac_seekable): Likewise. * src/ls.c (gobble_file): Likewise.
2015-05-28copy: prefer our hardlink to symlink emulation on OS X 10.10Pádraig Brady
* src/copy.c (CAN_HARDLINK_SYMLINKS): Don't enable use of linkat() on Darwin 14, as the gnulib fallback emulation there doesn't preserve ownership and timestamps etc. This fixes a test failure in tests/cp/link-symlink.sh * tests/cp/link-deref.sh: Adjust accordingly.
2015-05-26maint: remove sys/types.h include order checkPádraig Brady
* src/system.h: This was inadvertently ineffective due to a typo in commit v8.9-10-ge1aaf89 (Jan 2011), but has not caused any issues, so remove.
2015-05-23mkdir: fix -pZ with existing parent directoriesPádraig Brady
When the parent directory exists and has a different default context to the final directory, the context was incorrectly left as that of the parent directory. * src/mkdir.c (process_dir): Because defaultcon() is called for existing ancestors (as it must be to avoid races), then we must unconditionally call restorecon() on the last component due to the already documented caveat with make_dir_parents(). Alternatively you could temp disable o->set_security_context around make_dir_parents(), but that would be subject to races. * tests (tests/mkdir/restorecon.sh): Add a TODO for improvement. Reference mknod and mkfifo with print_ver_. * NEWS: Mention the bug fix. Fixes http://bugs.gnu.org/20616
2015-05-13timeout: with --foreground don't send SIGCONTPádraig Brady
* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program when --foreground is specified, as it's generally not needed for foreground programs, and can cause intermittent signal delivery issues with monitors like GDB for example. * doc/coreutils.texi (timeout invocation): Mention that SIGCONT is not sent with --foreground. * NEWS: Mention the behavior change.
2015-05-13split: auto set suffix len for --numeric-suffixes=<N --number=NPádraig Brady
Supporting `split --numeric-suffixes=1 -n100` for example. * doc/coreutils.texi (split invocation): Mention the two use cases for the FROM parameter, and the consequences on the suffix length determination. * src/split.c (set_suffix_length): Use the --numeric-suffixes FROM parameter in the suffix width calculation, when it's less than the number of files specified in --number. * tests/split/suffix-auto-length.sh: Add test cases. Fixes http://bugs.gnu.org/20511
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.
2015-05-11tail: consistently output all data for truncated filesPádraig Brady
Generally if logs are truncated, they're truncated to 0 length, so output all existing data when our heuristic determines truncation. Note with inotify, truncate() and write() are often determined independently and so all data would be written if that was the case. * src/tail.c (check_fspec): Reset file offset to 0 upon truncation. (tail_forever): Likewise. (recheck): Add a FIXME for the related issue where tail may lose data due to tail discounting older log files too early. * tests/tail-2/truncate.sh: A new test. * tests/local.mk: Reference the new test. * NEWS: Mention the fix.
2015-05-11tail: fix inotify startup racesPádraig Brady
The previous fixes to races in the various tail tests, identified actual races in the tail inotify implementation. With --follow=descriptor, if the tailed file was replaced before the inotify watch was added, then any subsequent changes were ignored. Similarly in --follow=name mode, all changes to a new name were effectively ignored if that name was created after the original open() but before the inotify_add_watch(). * src/tail.c (tail_forever_inotify): Fix 3 cases. 1. With -f, don't stop tailing when file removed before watch. 2. With -f, watch right file when file replaced before watch. 3. With -F, inspect correct file when replaced before watch. Existing tests identify these when tail compiled with TAIL_TEST_SLEEP. * tests/tail-2/inotify-rotate-resources.sh: This test also identifies the issue with --follow=name when TAIL_TEST_SLEEP is used. Adjust so the test is immune to such races, and also fail quicker on remote file systems. * tests/tail-2/inotify-race2.sh: A new test using GDB, based on inotify-race.sh, which tests the -F race without needed recompilation with sleeps. * tests/local.mk: Reference the new test. * NEWS: Mention the bug.
2015-05-10build: rewrite is_ENOTSUP without an #if directivePaul Eggert
* src/system.h (is_ENOTSUP): Avoid in-function #if directive.
2015-05-09build: avoid a warning form gcc's new -Wlogical-opJim Meyering
Without this change, very recent gcc (e.g., version 6.0.0 20150509) would print the following when configured with --enable-gcc-warnings: src/copy.c:165:30: error: logical 'or' of equal expressions \ [-Werror=logical-op] && (errno == EOPNOTSUPP || errno == ENOTSUP || errno == ENOSYS)) ^ * src/system.h (is_ENOTSUP): New function. * src/copy.c (punch_hole): Use it. * src/ls.c (errno_unsupported, gobble_file): Use it.
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
2015-04-28build: fix SINGLE_BINARY build when printf is a macroYunlian Jiang
* src/coreutils.c (usage): include coreutils.h outside the printf call, because if it's a macro you will get the error: embedding a #include directive within macro arguments is not supported
2015-04-28maint: avoid a new -Werror=return-type warning in yes.cPádraig Brady
* src/yes.c (main): Simplify the logic so that the compiler can see this function always returns a value. This was seen with GCC 5.0 in SINGLE_BINARY mode.
2015-04-27maint: fix printf format for signed integersPádraig Brady
With GCC 5 and the newly added warnings from gnulib, ensure the correct signed integer is passed for the printf format, to avoid -Werror=format= failures.
2015-04-26ls: on GNU/Linux, remove dependency on libaclPaul Eggert
* src/local.mk (src_ls_LDADD): Change from LIB_ACL to LIB_HAS_ACL.
2015-04-22build: fix potential factor build failure on arm and mipsPádraig Brady
* src/longlong.h: Sync with the latest longlong.h from libgmp to: - Use __builtin_c[lt]zl on arm64. - Fix sparc64 vis3 build failure due to missing __clz_tab. - Avoid a clang build issue on mips. - Support thumb2 arm 32 bit system. * src/cfg.mk (sc_ensure_comma_after_id_est): Exclude longlong.h to ease merges.
