3.25.1

Highlights

• http-destination: Users now can specify the action for any HTTP result code.
  Use with response-action(response_code => action) in your http block.
  Available actions are: success, retry, drop and disconnect. (#3007)
• syslog-ng-cfg-db: Added a new script, which can provide the options of
  sources and destinations queried by the user. This tool can make the configuration
  of syslog-ng a lot easier. Use with ./syslog-ng-cfg-db.py from the
  contrib/config_database dir.(#2997)
• redis-destination: Improved the performance by 2 orders of magnitude.
  In our labor environment, now it operates at 25k EPS. (#2972)

Features

• create-dirs(): Added to pipe() source/destination, and standardize the behavior.
  (#3018, #2635)
• default-network-drivers: Added max-connections() option, to change the limit
  from 10. (#2961)
• checkpoint: Added support for timezone value at the end of timestamps. (#3033)
• filter/rewrite: Added disable-jit flag to disable JIT PCRE compilation. (#2992, #2986)
• syslog-ng-ctl: Added export-config-graph option to visualize config graph. (#2990)

• build/dbld: Readded CentOS 6 support. (#2860, #2971, #3028)
• python: Added Python 3.8 support. (#3017)

Bugfixes

• tls: Fixed an infinite loop which occured, when a TLS connection broke. (#3026, #3009)
• log-block: Fixed an issue, where inline network destinations disjointed
  the rest of the config. (#2989, #2820)
• kafka/network-load-balancer: Fixed a crash when an argument was set to empty. (#3002)
• python-source: Fixed a memory corruption during reload. (#3014)

• telegram: Fixed the syntax error of the use-system-cert-store() option. (#2977)
• config: Throw error to single dots, which were ignored before. (#3000)
• file-destination: Delay ACKs until messages are written to disk. This fixes message
  drop on I/O error and message lost in the LogProtoFileWriter in case of a crash, by
  retrying to send the message. (#2985)
• http-destination: Handle global template options values. (#3020)
• timeutils: Fixed month and day name parsing, when only the first 2 characters
  matched. (#3035)
• logmsg: Added default PRI value (LOG_USER | LOG_NOTICE) to log messages
  created without initial parsing. (#2974)
