| 5 | | * Noteworthy changes in release 8.24 (2015-07-03) [stable] |
| 6 | | |
| 7 | | ** Bug fixes |
| 8 | | |
| 9 | | dd supports more robust SIGINFO/SIGUSR1 handling for outputting statistics. |
| 10 | | Previously those signals may have inadvertently terminated the process. |
| 11 | | |
| 12 | | df --local no longer hangs with inaccessible remote mounts. |
| 13 | | [bug introduced in coreutils-8.21] |
| 14 | | |
| 15 | | du now silently ignores all directory cycles due to bind mounts. |
| 16 | | Previously it would issue a warning and exit with a failure status. |
| 17 | | [bug introduced in coreutils-8.1 and partially fixed in coreutils-8.23] |
| 18 | | |
| 19 | | chroot again calls chroot(DIR) and chdir("/"), even if DIR is "/". |
| 20 | | This handles separate bind mounted "/" trees, and environments |
| 21 | | depending on the implicit chdir("/"). |
| 22 | | [bugs introduced in coreutils-8.23] |
| 23 | | |
| 24 | | cp no longer issues an incorrect warning about directory hardlinks when a |
| 25 | | source directory is specified multiple times. Now, consistent with other |
| 26 | | file types, a warning is issued for source directories with duplicate names, |
| 27 | | or with -H the directory is copied again using the symlink name. |
| 28 | | |
| 29 | | factor avoids writing partial lines, thus supporting parallel operation. |
| 30 | | [the bug dates back to the initial implementation] |
| 31 | | |
| 32 | | head, od, split, tac, tail, and wc no longer mishandle input from files in |
| 33 | | /proc and /sys file systems that report somewhat-incorrect file sizes. |
| 34 | | |
| 35 | | mkdir --parents -Z now correctly sets the context for the last component, |
| 36 | | even if the parent directory exists and has a different default context. |
| 37 | | [bug introduced with the -Z restorecon functionality in coreutils-8.22] |
| 38 | | |
| 39 | | numfmt no longer outputs incorrect overflowed values seen with certain |
| 40 | | large numbers, or with numbers with increased precision. |
| 41 | | [bug introduced when numfmt was added in coreutils-8.21] |
| 42 | | |
| 43 | | numfmt now handles leading zeros correctly, not counting them when |
| 44 | | settings processing limits, and making them optional with floating point. |
| 45 | | [bug introduced when numfmt was added in coreutils-8.21] |
| 46 | | |
| 47 | | paste no longer truncates output for large input files. This would happen |
| 48 | | for example with files larger than 4GiB on 32 bit systems with a '\n' |
| 49 | | character at the 4GiB position. |
| 50 | | [the bug dates back to the initial implementation] |
| 51 | | |
| 52 | | rm indicates the correct number of arguments in its confirmation prompt, |
| 53 | | on all platforms. [bug introduced in coreutils-8.22] |
| 54 | | |
| 55 | | shuf -i with a single redundant operand, would crash instead of issuing |
| 56 | | a diagnostic. [bug introduced in coreutils-8.22] |
| 57 | | |
| 58 | | tail releases inotify resources when unused. Previously it could exhaust |
| 59 | | resources with many files, or with -F if files were replaced many times. |
| 60 | | [bug introduced in coreutils-7.5] |
| 61 | | |
| 62 | | tail -f again follows changes to a file after it's renamed. |
| 63 | | [bug introduced in coreutils-7.5] |
| 64 | | |
| 65 | | tail --follow no longer misses changes to files if those files were |
| 66 | | replaced before inotify watches were created. |
| 67 | | [bug introduced in coreutils-7.5] |
| 68 | | |
| 69 | | tail --follow consistently outputs all data for a truncated file. |
| 70 | | [bug introduced in the beginning] |
| 71 | | |
| 72 | | tail --follow=name correctly outputs headers for multiple files |
| 73 | | when those files are being created or renamed. |
| 74 | | [bug introduced in coreutils-7.5] |
| 75 | | |
| 76 | | ** New features |
| 77 | | |
| 78 | | chroot accepts the new --skip-chdir option to not change the working directory |
| 79 | | to "/" after changing into the chroot(2) jail, thus retaining the current wor- |
| 80 | | king directory. The new option is only permitted if the new root directory is |
| 81 | | the old "/", and therefore is useful with the --group and --userspec options. |
| 82 | | |
| 83 | | dd accepts a new status=progress level to print data transfer statistics |
| 84 | | on stderr approximately every second. |
| 85 | | |
| 86 | | numfmt can now process multiple fields with field range specifications similar |
| 87 | | to cut, and supports setting the output precision with the --format option. |
| 88 | | |
| 89 | | split accepts a new --separator option to select a record separator character |
| 90 | | other than the default newline character. |
| 91 | | |
| 92 | | stty allows setting the "extproc" option where supported, which is |
| 93 | | a useful setting with high latency links. |
| 94 | | |
| 95 | | sync no longer ignores arguments, and syncs each specified file, or with the |
| 96 | | --file-system option, the file systems associated with each specified file. |
| 97 | | |
| 98 | | tee accepts a new --output-error option to control operation with pipes |
| 99 | | and output errors in general. |
| 100 | | |
| 101 | | ** Changes in behavior |
| 102 | | |
| 103 | | df no longer suppresses separate exports of the same remote device, as |
| 104 | | these are generally explicitly mounted. The --total option does still |
| 105 | | suppress duplicate remote file systems. |
| 106 | | [suppression was introduced in coreutils-8.21] |
| 107 | | |
| 108 | | mv no longer supports moving a file to a hardlink, instead issuing an error. |
| 109 | | The implementation was susceptible to races in the presence of multiple mv |
| 110 | | instances, which could result in both hardlinks being deleted. Also on case |
| 111 | | insensitive file systems like HFS, mv would just remove a hardlinked 'file' |
| 112 | | if called like `mv file File`. The feature was added in coreutils-5.0.1. |
| 113 | | |
| 114 | | numfmt --from-unit and --to-unit options now interpret suffixes as SI units, |
| 115 | | and IEC (power of 2) units are now specified by appending 'i'. |
| 116 | | |
| 117 | | tee will exit early if there are no more writable outputs. |
| 118 | | |
| 119 | | tee does not treat the file operand '-' as meaning standard output any longer, |
| 120 | | for better conformance to POSIX. This feature was added in coreutils-5.3.0. |
| 121 | | |
| 122 | | timeout --foreground no longer sends SIGCONT to the monitored process, |
| 123 | | which was seen to cause intermittent issues with GDB for example. |
| 124 | | |
| 125 | | ** Improvements |
| 126 | | |
| 127 | | cp,install,mv will convert smaller runs of NULs in the input to holes, |
| 128 | | and cp --sparse=always avoids speculative preallocation on XFS for example. |
| 129 | | |
| 130 | | cp will read sparse files more efficiently when the destination is a |
| 131 | | non regular file. For example when copying a disk image to a device node. |
| 132 | | |
| 133 | | mv will try a reflink before falling back to a standard copy, which is |
| 134 | | more efficient when moving files across BTRFS subvolume boundaries. |
| 135 | | |
| 136 | | stat and tail now know about IBRIX. stat -f --format=%T now reports the file |
| 137 | | system type, and tail -f uses polling for files on IBRIX file systems. |
| 138 | | |
| 139 | | wc -l processes short lines much more efficiently. |
| 140 | | |
| 141 | | References from --help and the man pages of utilities have been corrected |
| 142 | | in various cases, and more direct links to the corresponding online |
| 143 | | documentation are provided. |
