Release 1.1.0
* Incompatible change: sqlite3 and per_user behaviour:
Now both redis and sqlite3 follows the common principles for per-user
statistics:
1) If per-user statistics is enabled check per-user tokens ONLY
2) If per-user statistics is not enabled then check common tokens ONLY
If you need old behaviour, then you'd need to use separate classifier
for per-user statistics.
* Implement redis statistics backend and cache
* Implement autolearning for statistics
* Reworked statistics architecture from scratch
* Add hyperscan (https://github.com/01org/hyperscan) engine for regular
expressions:
- add lazy loader for hyperscan databases
- rework regexp cache to have joint pcre/hyperscan scanning
- implement hyperscan pre-filter support
- add compilation guards for bad expressions
- implement `rspamadm control recompile` command
- implement hyperscan cache monitoring
- slides: <https://highsecure.ru/rspamd-hyperscan.pdf>
* Implement flexible task logging
* Rework fuzzy worker:
- it is now possible to run multiple fuzzy workers;
- implement lazy writing as sqlite3 is bad at concurrent writing;
- add retries for simple sql commands in fuzzy backend;
- use fine-grained transactions for fuzzy;
- implement new multi-pubkeys mode;
- allow encrypted only storages;
- rework statistics for fuzzy;
- add `rspamadm control fuzzystat` command for extended statistics;
- implement human readable output for the previous command;
- add condition script for learning fuzzy storage;
* Various fixes to SPF:
- fix `redirect` records;
- fix domains when parsing mx/ptr/a records in includes/redirects;
- fix issues with multiple addresses in SPF records;
- ignore SPF results in case of DNS failure;
- adjust TTL of records when resolving subelements of SPF records;
- always select `v=spf1` line if it is available
- do not cache records with DNS failure in subrequests;
- ignore records with temporary fails during subrequests resolving;
- fix `RDNS_RC_NOREC` support;
