2016-11-05stat: make --format=%N honor the QUOTING_STYLE env varPádraig Brady
* doc/coreutils.texi (stat invocation): Describe the QUOTING_STYLE values now supported. * src/stat.c (getenv_quoting_style): A new function called from main, that sets the default quoting style for quotearg. (main): Call getenv_quoting_style() when %N specified. * tests/misc/stat-fmt.sh: Add a test case. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/23422
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, ...);
2016-05-12stat,tail: add support for the SMB2 remote file systemPádraig Brady
* stc/stat.c (human_fstype): Add file system ID definition, and use "smb2" as the name. * NEWS (Improvements): Mention the change. Fixes http://bugs.gnu.org/23516
2016-04-22stat,tail: add support for Windows Subsystem for LinuxPádraig Brady
* src/stat.c (human_fstype): Add file system ID definition, and use "wslfs" as the name. * NEWS (Improvements): Mention the change. Fixes http://bugs.gnu.org/23273
2016-04-14stat,tail: add support for M1FSYigal Korman
* src/stat.c (human_fstype): Add file system ID definition. * NEWS (Improvements): Mention the change, moving the previously added "prl_fs" change note from "Changes in behavior" to here. Fixes http://bugs.gnu.org/23283
2016-03-31stat: report type for "prl_fs" file systemsPádraig Brady
* src/stat.c (human_fstype): Identify the parallels file system. Also tag as remote so that tail(1) doesn't use inotify, which fails to detect changes made outside a VM. Fixes http://bugs.gnu.org/23143
2016-03-17date ls pr: fix time zone abbrs on SysV platformsPaul Eggert
The problematic code computed a struct tm in one time zone, and then printed it or converted it to a string in another. To be portable the same time zone needs to be used for both operations. On GNU platforms this is not an issue, but incorrect output can be generated on System V style platforms like AIX where time zone abbreviations are available only in the 'tzname' global variable. Problem reported by Assaf Gordon in: http://bugs.gnu.org/23035 * NEWS: Document the bug. * src/date.c (show_date): * src/ls.c (long_time_expected_width, print_long_format): * src/pr.c (init_header): * src/stat.c (human_time): Use localtime_rz instead of localtime, so that the time zone information is consistent for both localtime and time-formatting functions like fprintftime and nstrftime. For 'stat' this change is mostly just a code cleanup but it also causes stat to also print nanoseconds when printing time stamps that are out of localtime range, as this is more consistent with what other programs do. For programs other than 'stat' this fixes bugs with time zone formats that use %Z. * src/du.c, src/pr.c (localtz): New static var. (main): Initialize it. * src/du.c (show_date): New time zone argument, so that localtime and fprintftime use the same time zone information. All callers changed. * tests/misc/time-style.sh: New file. * tests/local.mk (all_tests): Add it. * tests/misc/date.pl: Test alphabetic time zone abbreviations.
2016-01-13doc: mention the '0#' printf flags with stat %aPádraig Brady
* src/stat.c (usage): Mention the '#' and '0' flags are useful with %a. * doc/coreutils.texi (stat invocation): Likewise. Also give an example printing unambiguous octal output. Reported at http://bugs.debian.org/810539
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.
2015-12-14stat: report file system type for "overlayfs"Pádraig Brady
* src/stat.c (human_fstype): Add "overlayfs", and tag it as "remote" to ensure that tail continues to use the more conservative polling mode. * README-release: Remove a stale comment about updating fremote() in tail.c. Also give a link to *_SUPER_MAGIC definitions not in the standard linux/magic.h location. * NEWS: Mention that this file system is recognized.
2015-11-11stat: improve support for new Linux pseudo FS and ACFSPádraig Brady
* src/stat.c (human_fstype): Add new file system ID definitions. * NEWS: Mention the improvement.
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.
2015-07-23build: 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.
2015-06-06build: 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.
2015-02-27tail,stat: improve support for the IBRIX file systemShane M Seymour
Note that IBRIX used to have a different magic number 0x013111A7 instead of the current 0x013111A8. However, the former is no longer used and the version of IBRIX it was used in is really ancient, so it's extremely unlikely anyone is still using it. Therefore, just add the newer magic number. Mark IBRIX as a 'remote' file system type as inotify support had never been officially tested with it. * src/stat.c (human_fstype): Add file system ID definition. * NEWS: Mention the improvement. Fixes http://bugs.gnu.org/19951
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.
2014-09-19doc: 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

(main): Use it. * src/logname.c, src/nohup.c, src/whoami.c: Use 'error' to simplify exit status in 'main' function. * src/yes.c (main): Use 'return' rather than 'error' to exit, so that GCC doesn't suggest ATTRIBUTE_NORETURN.
2014-06-13tail: fix --follow to use polling mode for VXFSPádraig Brady
Veritas File System can run in single instance or clustered mode, so mark as remote to avoid using inotify for the latter case. * src/stat.c (human_fstype): Tag VXFS as remote, to use polling for the clustered variant (VXCFS). * NEWS: Mention the bug fix. Reported by Ondřej Vašík in http://bugzilla.redhat.com/1104244 Fixes http://bugs.gnu.org/17770
2014-06-01stat: avoid redundant stat() callsPádraig Brady
* src/stat.c (find_bind_mount): NAME is invariant in the loop, so only stat(NAME) outside the loop.

2014-01-02maint: update all copyright year number rangesBernhard Voelker
Run "make update-copyright", but then also run this, perl -pi -e 's/2\d\d\d-//' tests/sample-test to make that one script use the single most recent year number.
2013-12-13stat,tail: improve support for hostfs and smackfsPádraig Brady
hostfs is provided by the Linux UML subsystem. smackfs is provided by the Linux Smack security module. * src/stat.c (human_fstype): Add new file system ID definitions. * NEWS: Mention the improvement, and adjust for the fact that SNFS is a remote file system.
2013-08-01doc: use semicolon instead of period in option descriptionsBenno Schulenberg
Also do not end option descriptions with a period, properly indent continuation lines, and make some tiny clarifications. * src/du.c (usage): Lowercase after semicolon. * src/ls.c (usage): Semicolons instead of periods, small rephrasing and two hyphens for clarity, proper indentation. * src/mktemp.c (usage): Semicolons and lowercase. * src/od.c (usage): Semicolons. * src/ptx.c (usage): Use the standard phrase, clarify default option. * src/setuidgid.c (usage): Properly indent continuation line. * src/split.c (usage): Semicolons, lowercase, no final period. * src/stat.c (usage): Semicolons, lowercase. * src/tail.c (usage): Proper indentation, one shorter rephrasing, semicolons, no final periods. * src/timeout.c (usage): Properly indent, semicolons, no final periods.

2013-07-02stat: ensure --context emits an "unrecognized option" diagnosticPádraig Brady
* src/stat.c (long_options): Remove the "context" option as it's no longer referenced since commit v8.5-65-g13f3237
2013-05-24stat: tune for large-LDAP casePaul Eggert
* src/stat.c (print_stat): Omit unnecessary calls to setpwent, setgrent. Problem reported by Fridolín Pokorný in <http://bugs.gnu.org/14462>.

2013-02-20maint: cleanup up various uses of __attribute__Pádraig Brady
* src/cfg.mk (sc_prohibit-gl-attributes): Disallow the __attribute() form without trailing underscores as that is not elided where required. Also ensure we use gnulib macros rather than defining our own. * src/system.h: Remove gnulib provided macros. * src/chown-core.c: Likewise. * src/chroot.c: Likewise. * src/copy.c: Likewise. * src/csplit.c: Likewise. * src/dd.c: Likewise. * src/expr.c: Likewise. * src/extent-scan.c: Likewise. * src/factor.c: Likewise. * src/ls.c: Likewise. * src/od.c: Likewise. * src/paste.c: Likewise. * src/ptx.c: Likewise. * src/sort.c: Likewise. * src/stat.c: Likewise. * src/stty.c: Likewise. * src/system.h: Likewise. * src/tac.c: Likewise. * src/test.c: Likewise. * src/tsort.c: Likewise.
2013-01-23maint: define usage note about mandatory args centrallyBernhard Voelker
Each program with at least one long option which is marked as 'required_argument' and which has also a short option for that option, should print a note about mandatory arguments. Define that well-known note centrally and use it rather than literal printf/fputs, and add it where it was missing. * src/system.h (emit_mandatory_arg_note): Add new function. * src/cp.c (usage): Use it rather than literal printf/fputs. * src/csplit.c, src/cut.c, src/date.c, src/df.c, src/du.c: * src/expand.c, src/fmt.c, src/fold.c, src/head.c, src/install.c: * src/kill.c, src/ln.c, src/ls.c, src/mkdir.c, src/mkfifo.c: * src/mknod.c, src/mv.c, src/nl.c, src/od.c, src/paste.c: * src/pr.c, src/ptx.c, src/shred.c, src/shuf.c, src/sort.c: * src/split.c, src/stdbuf.c, src/tac.c, src/tail.c, src/timeout.c: * src/touch.c, src/truncate.c, src/unexpand.c, src/uniq.c: Likewise. * src/base64.c (usage): Add call of the above new function because at least one long option has a required argument. * src/basename.c, src/chcon.c, src/date.c, src/env.c: * src/nice.c, src/runcon.c, src/seq.c, src/stat.c, src/stty.c: Likewise.

2012-12-15tail,stat: improve support for the ceph file systemBernhard Voelker
Teach tail -f that it must use polling on ceph file systems, and let stat -f --format=%T report the file system type name, "ceph". Website: http://ceph.com/ * src/stat.c (human_fstype): Add a case: ceph, 0x00C36400, remote. * NEWS (Improvements): Mention it. * THANKS.in: Update. Reported by Konrad Wróblewski in http://bugs.gnu.org/13172.
2012-09-23tail,stat: improve support for vmhgfsJim Meyering
Teach tail -f that it must use polling on vmhgfs file systems, and let stat -f --format=%T report the file system type name, "vmhgfs". * src/stat.c (human_fstype): Add a case: vmhgfs, 0xbacbacbc, remote. * NEWS (Improvements): Mention it. * THANKS.in: Update. Reported by Daniel Tschinder in http://bugs.gnu.org/12461.

2012-08-29tail,stat: improve support for ZFSJim Meyering
This change enables tail -f to use inotify and lets stat -f --format=%T report the file system type name, "zfs". * src/stat.c (human_fstype): Add a case: zfs, 0x2fc12fc1. * NEWS (Improvements): Mention it. * THANKS.in: Update. Reported by Raimonds Miltins in http://bugs.gnu.org/12301.
2012-06-30stat,tail: recognize new file system type: aufsJim Meyering
* src/stat.c (human_fstype) [__linux__]: Add a 'case' for the new remote file system type: aufs (0x61756673). * NEWS (New features): Mention stat -f. (Bug fixes): Mention it for tail -f. Reported by Michael Mol in http://bugs.gnu.org/11823
2012-06-01stat,tail: recognize new file system type: panfsJim Meyering

2012-05-16stat: report the correct block size for file system usagePádraig Brady
struct statfs has the f_frsize member since Linux 2.6, so use that rather than f_bsize which can be different. Note the related df change mentioned in NEWS is handled in gnulib by using statvfs() rather than statfs() on Linux > 2.6.36 (where statvfs doesn't hang) and the same method as stat for Linux 2.6 kernels earlier than that. stat(1) doesn't use statvfs() on GNU/Linux as the f_type member isn't available there. Note the change to not use statvfs() on GNU/Linux was introduced in gnulib commit eda39b8 16-08-2003. * m4/stat-prog.m4 (cu_PREREQ_STAT_PROG): Check for the f_frsize member in the statfs structure. * src/stat.c: Use (struct statfs).f_frsize if available. * NEWS (Bug fixes): Mention this stat fix, and the related df fix coming in the next gnulib update. * THANKS.in: Add Nikolaus. Reported and Tested by Nikolaus Rath
2012-05-10stat,tail: recognize new FS types: bdevfs, inodefs, qnx6Jim Meyering
* src/stat.c (human_fstype) [__linux__]: Add 'case's for these local file system types: bdevfs (0x62646576), inodefs (0x42494E4D), qnx6 (0x68191122). Now that the kernel has a name for S_MAGIC_BINFMTFS, use theirs in place of our S_MAGIC_BINFMT_MISC. * NEWS (New features): Mention it.
2012-05-09stat: don't report negative file size as huge positive numberPaul Eggert
* src/stat.c (print_stat): Use out_int, not out_uint for stat.st_size. * NEWS (Bug fixes): Mention it.
2012-01-20stat: clarify the description of the %o stat formatPádraig Brady
* src/stat.c (usage): Indicate this is a transfer size suggestion, rather than some persistent block size. * doc/coreutils.texi (stat invocation): Likewise.
2012-01-11maint: fix minor whitespace issuesPádraig Brady
The previous commit introduced a couple of spacing issues, luckily one of which caused a test to fail. * src/stat.c (default_format): Add a space so times are aligned. * src/tr.c (string2_extentd): Remove an extraneous space.
2012-01-11maint: adjust formatting of certain continued stringsJim Meyering
Add a rule to ding any source file that has a continued string with a word in the first column of the following line. Those tend to trigger malfunction in tools that try to map an arbitrary line number to an enclosing function name. Of course, very many strings do precisely this, *when they are part of the usage function*. So we exempt the body of each usage function. * src/dircolors.c (main): Separate a long, continued string into two separately-quoted parts. * src/od.c (decode_one_format): Likewise. (decode_one_format, main): Move a space from end of preceding line to the beginning of the continued line. * src/tr.c (unquote, string2_extend, validate): Likewise. * src/seq.c (main): Split in two and use string concatenation. * src/stat.c (default_format): Use a mix of techniques. * cfg.mk (sc_prohibit_continued_string_alpha_in_column_1): New rule. Exempt three files in src: system.h, od.c, printf.c.
