Changelog

This changelog is outdated. It will be updated later.

Unreleased

  • Added new CLI options:
    • -v, --version
    • -m, --memload
    • --monitor
    • --tasks
    • --check-config
  • Possible process crashes are fixed:
    • Fixed crash at startup due to UnicodeDecodeError on some systems
    • Handled UnicodeDecodeError if victim name consists of many unicode characters (rfjakob/earlyoom#110)
    • Fixed process crash before performing corrective actions if Python 3.4 or lower are used to interpret nohang
  • Improve output:
    • Display oom_score, oom_score_adj, Ancestry, EUID, State, VmSize, RssAnon, RssFile, RssShmem, CGroup_v1, CGroup_v2, Realpath, Cmdline and Lifetime of the victim in corrective action reports
    • Added memory report interval
    • Added delta memory info (the rate of change of available memory)
    • Print statistics on corrective actions after each corrective action
    • Added ability to print a process table before each corrective action
    • Added the ability to log into a separate file
  • Improved GUI warnings:
    • Reduced the idle time of the daemon in the process of launching a notification
    • All notify-send calls are made using the nohang_notify_helper script, in which all timeouts are handled (not anymore: nohang_notify_helper has been removed)
    • Native python implementation of env search without running ps to notify all users if nohang started with UID=0.
  • Improved modifing badness via matching with regular expressions:
    • Added the ability to set many different badness_adj for processes depending on the matching Name, CGroup_v1, CGroup_v2, cmdline, realpath, environ and EUID with the specified regular expressions (issue #11)
    • Fix: replace re.fullmatch() by re.search()
  • Reduced memory usage:
    • Reduced memory usage and startup time (using sys.argv instead of argparse)
    • Reduced memory usage with mlockall() using MCL_ONFAULT (rfjakob/earlyoom#112)
  • Lock all memory by default using mlockall()
  • Added new tools:
    • oom-sort
    • psi-top
    • psi2log
  • Improve poll rate algorithm
  • Fixed Makefile for installation on CentOS 7 (remove gzip -k option).
  • Added max_post_sigterm_victim_lifetime option: send SIGKILL to the victim if it doesn't respond to SIGTERM for a certain time
  • Added post_kill_exe option (the ability to run any command after killing a victim)
  • Added warning_exe option (the ability to run any command instead of GUI low memory warnings)
  • Added victim_cache_time option
  • Improved victim search algorithm (do it ~30% faster) (rfjakob/earlyoom#114)
  • Improved limiting oom_score_adj: now it can works with UID != 0
  • Fixed conf parsing: use of line.partition('=') instead of line.split('=')
  • Removed self-defense options from the config, use systemd unit scheduling instead
  • Added the ability to send any signal instead of SIGTERM for processes with certain names
  • Added support for PSI
  • Recheck memory levels after finding a victim to prevent killing innocent victims in some cases (issue #20)
  • Now one corrective action to one victim can be applied only once.
  • Ignoring zram by default, checking for this has become optional.
  • Improved user input validation
  • Improved documentation
  • Handle signals (SIGTERM, SIGINT, SIGQUIT, SIGHUP), print total stat by corrective actions at exit.
