nohang/CHANGELOG.md at ba737b8f44f60d8ab0d50d09566ec6fce9581090

Added new CLI options:

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
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:

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.
