Note, we have used + Mac in Travis-CI (see .travis.yml). + + - add Coverity to GitHub Actions (see for example .github/workflows/coverity.yml + in systemd repo). + +fstrim +------ + - "fstrim --fstab" uses root= from /proc/cmdline to get root FS when it's missing + in fstab file. This is fragile (due to missing root= or the root FS is not + accessible). The best seems to parse mountinfo and use mnt_table_get_root_fs() + as a fallback solution. https://github.com/util-linux/util-linux/issues/1266. + +script (lib/pty-session.c) +-------------------------- + - (!) add #ifdefs and optional code for non-signalfd() systems + +docs +---- + - use terminal hyperlinks (for example for --help) + try on terminal: printf 'For more details see \e]8;;man:fdisk(8)\e\\fdisk(8)\e]8;;\e\\.\n' + https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda + +rev +--- + - support huge input lines (for example read input by small fixed buffer + rather than try allocate all buffer for a whole line) + see: https://github.com/util-linux/util-linux/issues/972 + +col +--- + - use unsigned sizes for columns and lines + - check for limits to avoid segfaults + - make it more robust + https://github.com/util-linux/util-linux/issues/749 + +cal +--- + - support another --reforms, see for example freebsd version + https://github.com/freebsd/freebsd/blob/master/usr.bin/ncal/ncal.c#L72 + +lscpu +----- + - add "Boost/Turbo: true|false" based on /sys/devices/system/cpu/intel_pstate/no_turbo and + /sys/devices/system/cpu/cpufreq/boost + + - add --freq output to visualise CPU use, see https://github.com/util-linux/util-linux/issues/1314 + + - read cpuid and uname information from file if --sysroot is specified, then + we can prepare regression tests completely independent on hw and architecture. + +hwclock +------ + - use /var/lib/hwclock/drift to store hw-clock drift numbers. + - use /etc/adjtime as read-only for UTC/LOCAL information only + - the /var/lib/hwclock/drift should be implemented backwardly compatible, + it means use the file only if exists, otherwise follow /etc/adjtime + - see topic/hwclock-drift-file branch + +bash completion +--------------- +- Optional argument handling requires user to press backspace to get + argument completion. +- Comma separated value, e.g., --output 'value1,value2', are not + completed for users. + +libmount (mount/umount) +----------------------- + + - mnt_context_get_excode() does not return error messages from /sbin/[u]mount.<type> + external helpers. It is disadvantages in same cases (non-terminal programs). + The solution is to use pipe(), keep output from helper in memory and return it later + by mnt_context_get_excode() (or mnt_context_get_helper_output(), etc.). This feature + should be optional and disabled by default. + see: https://github.com/util-linux/util-linux/issues/1208 + + - add --onlyonce to force mount(8) to check if mountpoint is already used. Now + "already mounted" detection is used for --all only. The problem is if you + call "mount <mountpoint>" more than once for in fstab defined tmpfs (or network + filesystem etc.). In this case kernel does not return EBUSY, but a new instance + of the FS is created. https://github.com/util-linux/util-linux/issues/448 + (... just idea, maybe wrong idea) + + - Extend mount(8) command line for mount flags modification without remount: + "mount modify --clear noexec --set nodev,private,ro /mnt" + This functionality should be implemented by mount_setattr() syscall. + +partx +----- + + - support mapping by device-mapper if argv[0] is "kpartx" or --dm option is used. + + +getopt +------ + It would be great if getopt could optionally ignore unknown options. + Currently, it outputs -- for every option it doesn't recognize but leaving the + option as it is could beneficial wrapper scripts which could then pass the + options they don't recognize as they are to the command they are wrapping. + https://github.com/util-linux/util-linux/issues/701 + +docs +---- + + - (!) use something better than gtk-doc for libmount and libblkid (doxygen?) + + - (!) add API documentation to libuuid + + - Improve line breaks in man pages and review markup + + +login-utils: +----------- + + - consolidate newgrp(1) + * we have "su --group/--supp-group" to switch between groups, newgrp(1) in + util-linux and shadow-utils (and sg(1) alias in shadow-utils) + * the unique functionality provided by newgpr(1) is support for group + passwords [/etc/gshadow] -- do we really need this functionality? + * maybe we can mark group-passwords as deprecated, and replace sg(1) and + newgpr(1) with su(1) code.
