It also includes + fields with some process statistics information. + See https://doc.dovecot.org/admin_manual/list_of_events/ for more + information. + + Added process_shutdown_filter setting. When an event matches the filter, + the process will be shutdown after the current connection(s) have + finished. This is intended to reduce memory usage of long-running imap + processes that keep a lot of memory allocated instead of freeing it to + the OS. + + auth: Add cache hit indicator to auth passdb/userdb finished events. + See https://doc.dovecot.org/admin_manual/list_of_events/ for more + information. + + doveadm deduplicate: Performance is improved significantly. + + imapc: COPY commands were sent one mail at a time to the remote IMAP + server. Now the copying is buffered, so multiple mails can be copied + with a single COPY command. + + lib-lua: Add a Lua interface to Dovecot's HTTP client library. See + https://doc.dovecot.org/admin_manual/lua/ for more information. + - auth: Cache lookup would use incorrect cache key after username change. + - auth: Improve handling unexpected LDAP connection errors/hangs. + Try to fix up these cases by reconnecting to the LDAP server and + aborting LDAP requests earlier. + - auth: Process crashed if userdb iteration was attempted while auth-workers + were already full handling auth requests. + - auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary + introspection requests. + - dict: Timeouts may have been leaked at deinit. + - director: Ring may have become unstable if a backend's tag was changed. + It could also have caused director process to crash. + - doveadm kick: Numeric parameter was treated as IP address. + - doveadm: Proxying can panic when flushing print output. Fixes + Panic: file ioloop.c: line 865 (io_loop_destroy): assertion failed: + (ioloop == current_ioloop). + - doveadm sync: BROKENCHAR was wrongly changed to '_' character when + migrating mailboxes. This was set by default to %, so any mailbox + names containing % characters were modified to "_25". + - imapc: Copying or moving mails with doveadm to an imapc mailbox could + have produced "Error: Syncing mailbox '[...]' failed" Errors. The + operation itself succeeded but attempting to sync the destination + mailbox failed. + - imapc: Prevent index log synchronization errors when two or more imapc + sessions are adding messages to the same mailbox index files, i.e. + INDEX=MEMORY is not used. + - indexer: Process was slowly leaking memory for each indexing request. + - lib-fts: fts header filters caused binary content to be sent to the + indexer with non-default configuration. + - doveadm-server: Process could hang in some situations when printing + output to TCP client, e.g. when printing doveadm sync state. + - lib-index: dovecot.index.log files were often read and parsed entirely, + rather than only the parts that were actually necessary. This mainly + increased CPU usage. + - lmtp-proxy: Session ID forwarding would cause same session IDs being + used when delivering same mail to multiple backends. + - log: Log prefix update may have been lost if log process was busy. + This could have caused log prefixes to be empty or in some cases + reused between sessions, i.e. log lines could have been logged for the + wrong user/session. + - mail_crypt: Plugin crashes if it's loaded only for some users. Fixes + Panic: Module context mail_crypt_user_module missing. + - mail_crypt: When LMTP was delivering mails to both recipients with mail + encryption enabled and not enabled, the non-encrypted recipients may + have gotten mails encrypted anyway. This happened when the first + recipient was encrypted (mail_crypt_save_version=2) and the 2nd + recipient was not encrypted (mail_crypt_save_version=0). + - pop3: Session would crash if empty line was sent. + - stats: HTTP server leaked memory. + - submission-login: Long credentials, such as OAUTH2 tokens, were refused + during SASL interactive due to submission server applying line length + limits. + - submission-login: When proxying to remote host, authentication was not + using interactive SASL when logging in using long credentials such as + OAUTH2 tokens. This caused authentication to fail due to line length + constraints in SMTP protocol. + - submission: Terminating the client connection with QUIT command after + mail transaction is started with MAIL command and before it is + finished with DATA/BDAT can cause a segfault crash. + - virtual: doveadm search queries with mailbox-guid as the only parameter + crashes: Panic: file virtual-search.c: line 77 (virtual_search_get_records): + assertion failed: (result != 0) + v2.3.18 2022-02-03 Aki Tuomi * Removed mail_cache_lookup_finished event.
