- update to 2.3.21 and pigeonhole 0.5.21
Dovecot 2.3.21
* lib-oauth2: Allow JWT tokens to be validated with missing typ field.
The typ field is left out by some key issuers to conserve space,
notably kubernetes. Now missing typ is tolerated, but if present, it
still must be "jwt".
+ auth: Auth passdb and userdb reply can contain "event_<name>=value"
which will be added to login event and mail user event respectively.
+ lib-master: Set process title during various initialization stages to
clearly describe what the process is waiting on.
+ lib-storage: The mail_temp_scan_interval is now fuzzed incrementing it
by 0..30% based on username's hash to reduce the chance of load spikes.
+ lib-storage: The temp file scan has been moved from the open of the
mailbox to the close, to reduce the latency perceived by users.
+ stats: If metric has fields specified, all these fields are
exported as counters to prometheus exposition.

- Add support for Zstandard (zstd) to the compression (zlib) plugin: zstd has a
better compression ratio than gzip for the same amount of CPU work, or takes
less CPU to compress the same. It's also faster to decompress.
- Add dovecot-2.3.19-fix-doveadm-sync-special-folders.patch:
Patches from the release-2.3 branch that fix issues importing the INBOX
folder from a Cyrus IMAP server and dealing with auto-creating folders that
haven't yet been created

- update to 2.3.19 and pigeonhole 0.5.19
Dovecot 2.3.19
+ Added mail_user_session_finished event, which is emitted when the mail
user session is finished (e.g. imap, pop3, lmtp). 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.

- update to 2.3.14 and pigeonhole to 0.5.14
* removed obsolete fix-timeval_cmp_margin-for-32bit-systems.patch
Dovecot 2.3.14
* Added new aliases for some variables. Usage of the old ones is possible,
but discouraged. (These were partially added already to v2.3.13.)
See https://doc.dovecot.org/configuration_manual/config_file/config_variables/
for more information.
* Optimize imap/pop3/submission/managesieve proxies to use less CPU at
the cost of extra memory usage.
* Remove autocreate, expire, snarf and mail-filter plugins.
* Remove cydir storage driver.
* Remove XZ/LZMA write support. Read support will be removed in future release.
* doveadm -D: Add timestamps to debug output even when LOG_STDERR_TIMESTAMP
environment variable is not set. Timestamp format is taken from
log_timestamp setting.
* If BROKENCHAR or listescape plugin is used, the escaped folder names
may be slightly different from before in some situations. This is
unlikely to cause issues, although caching clients may redownload the
folders.
* imapc: It now enables BROKENCHAR=~ by default to escape remote folder
names if necessary. This also means that if there are any '~'
characters in the remote folder names, they will be visible as "~7e".
* imapc: When using local index files folder names were escaped on
filesystem a bit differently. This affects only if there are folder
names that actually require escaping, which isn't so common. The old
style folders will be automatically deleted from filesystem.
* stats: Update exported metrics to be compliant with OpenMetrics standard.
+ doveadm: Add an optional '-p' parameter to metadata list command. If
enabled, "/private", and "/shared" metadata prefixes will be prepended
to the keys in the list output.
+ doveconf: Support environment variables in config files. See
https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#environment-variables
for more details.
+ indexer-worker: Change indexer to disconnect from indexer-worker
after each request. This allows service indexer-worker's service_count &
idle_kill settings to work. These can be used to restart indexer-worker
processes once in a while to reduce their memory usage.
- auth: "nodelay" with various authentication mechanisms such as apop
and digest-md5 crashed AUTH process if authentication failed.
- auth: Auth lua script generating an error triggered an assertion
failure: Panic: file db-lua.c: line 630 (auth_lua_call_password_verify):
assertion failed: (lua_gettop(script->L) == 0).
- configure: Fix libunwind detection to work on other than x86_64 systems.
- doveadm-server: Process could crash if logging was done outside command
handling. For example http-client could have done debug logging
afterwards, resulting in either segfault or Panic:
file http-client.c: line 642 (http_client_context_close):
assertion failed: (cctx->clients_list == NULL).
- dsync: Folder name escaping with BROKENCHAR didn't work completely
correctly. This especially caused problems with dsync-migrations using
imapc where some of the remote folder names may not have been accessible.
- dsync: doveadm sync + imapc doesn't always sync all mails when doing
an incremental sync (-1), which could lead to mail loss when it's used
for migration. This happens only when GUIDs aren't used (i.e.
imapc without imapc_features=guid-forced).
- fts-tika: When tika server returns error, some mails cause Panic:
file message-parser.c: line 802 (message_parser_deinit_from_parts):
assertion failed: (ctx->nested_parts_count == 0 || i_stream_have_bytes_left(ctx->input))
- lib-imap: imapc parsing illegal BODYSTRUCTUREs with NILs could have
resulted in crashes. This exposed that Dovecot was wrongly accepting
atoms in "nstring" handling. Changed the IMAP parsing to be more
strict about this now.
- lib-index: If dovecot.index.cache has corrupted message size, fetching
BODY/BODYSTRUCTURE may cause assert-crash:
Panic: file index-mail.c: line 1140 (index_mail_parse_body_finish):
assertion failed: (mail->data.parts != NULL).
- lib-index: Minor error handling and race condition fixes related to
rotating dovecot.index.log. These didn't usually cause problems,
unless the log files were rotated rapidly.
- lib-lua: Lua scripts using coroutines or lua libraries using coroutines
(e.g., cqueues) panicked.
- Message PREVIEW handled whitespace wrong so first space would get
eaten from between words.
- FTS and message PREVIEW (snippet) parsed HTML &entities case-sensitively.
- lib-mail: When max nested MIME parts were reached, IMAP BODYSTRUCTURE
was written in a way that may have caused confusion for IMAP clients
and also Dovecot itself when parsing it. The truncated part is now
written out using application/octet-stream MIME type.
- lib-oauth2: HS512 and HS384 JWT token algorithms crash when you try to
use them: Panic: file hmac.c: line 26 (hmac_init): assertion failed:
(meth->context_size <= MAC_MAX_CONTEXT_SIZE).
- event filters: NOT keyword did not have the correct associativity.
NOT a AND b were getting parsed as NOT (a AND b) instead of
(NOT a) AND b.
- Ignore ECONNRESET when closing socket. This avoids logging useless
errors on systems like FreeBSD.
- event filters: event filter syntax error may lead to Panic:
file event-filter.c: line 137 (event_filter_parse): assertion failed:
(state.output == NULL)
- lib: timeval_cmp_margin() was broken on 32-bit systems. This could
potentially have caused HTTP timeouts to be handled incorrectly.
- log: instance_name wasn't used as syslog ident by the log process.
- master: After a service reached process_limit and client_limit, it
could have taken up to 1 second to realize that more client connections
became available. During this time client connections could have been
unnecessarily rejected and a warning logged:
Warning: service(...): process_limit (...) reached, client connections are being dropped
- stats: Crash would occur when generating openmetrics data for metrics
using aggregating functions.
- stats: Event filters comparing against empty strings crash the stats
process.

information.
* Metric filter and global event filter variable syntax changed to a
SQL-like format. See
https://doc.dovecot.org/configuration_manual/event_filter/
* auth: Added new aliases for %{variables}. Usage of the old ones is
possible, but discouraged.
* auth: Removed RPA auth mechanism, SKEY auth mechanism, NTLM auth
mechanism and related password schemes.

* auth: Removed postfix postmap socket
+ auth: Added new fields for auth server events. These fields are now
also available for all auth events. See
https://doc.dovecot.org/admin_manual/list_of_events/#authentication-server

+ imap-hibernate: Added imap_client_hibernated, imap_client_unhibernated
and imap_client_unhibernate_retried events. See
https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ lib-index: Added new mail_index_recreated event. See
https://doc.dovecot.org/admin_manual/list_of_events/#mail-index-recreated
+ lib-sql: Support TLS options for cassandra driver. This requires
cpp-driver v2.15 (or later) to work reliably.
+ lib-storage: Missing $HasAttachment / $HasNoAttachment flags are now
added to existing mails if mail_attachment_detection_option=add-flags
and it can be done inexpensively.
+ login proxy: Added login_proxy_max_reconnects setting (default 3) to
control how many reconnections are attempted.
