util: close all fds before freezing execution

[thirdparty/systemd.git] / TODO

F15:

* swap units that are activated by one name but shown in the kernel under another are semi-broken

* dep cycle basic → udev-retry → auditd → iptables → basic

* isolate multi-user.target doesn't start a getty@tty1 if we run it from graphical.target

* NFS, networkmanager ordering issue

* add fstab fields to add wait timeouts, change Wants to Requires by local-fs.target

* hook emergency.target into local-fs.target in some way as OnFailure with isolate

* mount /dev/.run and /var/run as bind mounts

* drop SIGHUP handling from rsyslog.service upstream

* teach dbus to activate all services it finds in /etc/systemd/services/org-*.service

* save/restore tool for SysV as requested by FPC

* bind mounts are ignored

* 0595f9a1c182a84581749823ef47c5f292e545f9 is borked, freezes shutdown

Features:

* optionally create watched directories in .path units

* consider services with no [Install] section and stored in /lib enabled by "systemctl is-enabled"

* consider services with any kind of link in /etc/systemd/system enabled

* show failure error string in "systemctl status"

* make sure timeouts are applied to Type=oneshot services.

* maybe implement "systemctl mask" and "systemctl unmask", but not
  document it? When doing that add switch to make this temporary by
  placing mask links in /dev.

* detect LXC environment

* invoke vhangup() before and after invoking getty

* support "auto" and "comment=systemd.automount" at the same time for an fstab entry

* Maybe store in unit files whether a service should be enabled by default on package installation

* perhaps add "systemctl reenable" as combination of "systemctl disable" and "systemctl enable"

* need a way to apply mount options of api vfs from systemd unit files
  (or some other modern source?) instead of fstab

* maybe introduce ExecRestartPre=

* figure out what happened to bluez patch

* Patch systemd-fsck to use -C and pass console fd to it

* support remote/ssh systemctl/systemadm, and local privileged access

* configurable jitter for timer events

* Support ProcessNeededForShutdown=true to allow stuff like mdmon
  to be killed very late after the rootfs is read only (?)

* Integrate "mdadm --wait-clean". Maybe just let SIGTERM to mdmon trigger the
  needed action

* dot output for --test showing the 'initial transaction'

* calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)
  - check timerfd() patch: http://lkml.org/lkml/2010/11/23/290

* systemd --user
  - get PR_SET_ANCHOR merged: http://lkml.org/lkml/2010/2/2/165

* add VT tracking:
    - provide CK functionality
    - start getty only when actual vt switch happens (same model as
      socket on-demand activation). allocate the next free tty and
      start a getty there. this way, pressing alt-f[1-12] will switch
      through running X and getty sessions, and any unallocated
      activated tty will start a new getty. the hardcoding of
      getty[1-6] will entirely go away.

* implicitly import "defaults" settings file into all types

* port over to LISTEN_FDS/LISTEN_PID:
   - uuidd    DONE
   - dbus     DONE
   - rsyslog  DONE
   - rpcbind (/var/run/rpcbind.sock!) DONE
   - cups     DONE
   - avahi-daemon (/var/run/avahi-daemon/socket) DONE
   - ssh      CLASSIC
   - postfix, saslauthd
   - apache/samba
   - libvirtd (/var/run/libvirt/libvirt-sock-ro)
   - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
   - distccd

* fingerprint.target, wireless.target, gps.target

* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!

* io priority during initialization

* if a service fails too often, make the service enter failed mode, and the socket, too.

* systemctl list-jobs - show dependencies

* accountsservice is borked

* auditd service files

* add systemctl switch to dump transaction without executing it

* suspend, resume

* readahead: btrfs/LVM SSD detection

* add separate man page for [Install] settings

* only add quotacheck deps to .mount units which mention grpquota/usrquota in the mount flags

* systemctl condrestart should return 0 if service isn't running

* allow runtime changing of log level and target

External:

* udisks should not use udisks-part-id, instead use blkid. also not probe /dev/loopxxx

* snd-seq should go, https://bugzilla.redhat.com/show_bug.cgi?id=676095

* gnome-shell python script/glxinfo/is-accelerated wech

* make cryptsetup lower --iter-time

* patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup.

* patch kernel for cpu feature modalias for autoloading aes/kvm/...
    http://git.kernel.org/?p=linux/kernel/git/ak/linux-misc-2.6.git;a=shortlog;h=refs/heads/cpuid-match

* procps, psmisc, sysvinit-tools, hostname → util-linux-ng

Regularly:

* look for close() vs. close_nointr() vs. close_nointr_nofail()

* check for strerror(r) instead of strerror(-r)

* Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel

* %m in printf() instead of strerror();

* pahole

* CFLAGS="-Wl,--gc-sections -Wl,--print-gc-sections -ffunction-sections -fdata-sections"
