imap: Add client_create_finish() to finish namespace creation.

imap: Add client_command_context.event and use it as global event while running

imap: Add client.event and use it as mail_*user's parent event

imap, pop3: Remove unnecessary call to mail_storage_service_io_deactivate() The context is automatically deactivated when service user is freed.

imap: Drop dependencies on lib-lda settings. Start using lib-smtp/smtp-submit-settings instead. Put any other settings required by IMAPSIEVE in struct imap_settings.

imap: Add %{appended} to imap_logout_format

imap-client: Add %{autoexpunged} to imap_logout_format

imap-client: Add const char *disconnect_reason to client This is to allow using reason given to client_disconnect() via timeout context.

imap: Don't do autoexpunging when IMAP client is hibernated

imap: Move struct client_sync_context to imap-sync-private.h and add imap_ prefix

imap: Allow plugins to hook into syncing. Ideally all of the existing pieces in the syncing code would start using this at some point, so their code could be moved to a more logical location.

imap: Add client_add_capability()

imap: Add imap_client_vfuncs.send_tagline() This allows plugins to catch all the IMAP command replies.

imap: Add client_command_context.human_args Generated with imap_write_args_for_human()

imap: Fix running time in tagged command replies. The timing information was updated only after command_exec() returned. Most of the commands were handled within a single command_exec() though, so at the time when tagline was sent the running_usecs was still zero. The msecs in ioloop timing was correct though, because it relied only on the command start timing info.

imap: Include info about last command in disconnection log line. Only if LOGOUT isn't sent, because that's already visible.

imap: Add imap_client.logged_out at LOGOUT This is useful for determining if client did a clean logout

imap: Code cleanup - move command stats to struct client_command_stats

imap: Add imap_fetch_failure setting This controls what happens when FETCH fails for some mails. The possible values are: disconnect-immediately: This is the original behavior. Whenever FETCH fails for a mail, the FETCH is aborted and client is disconnected. disconnect-after: The FETCH runs for all the requested mails, skipping any mails that returned failures, but at the end the client is still disconnected. no-after: The FETCH runs for all the requested mails, skipping any mails that returned failures. At the end tagged NO reply is returned. If the client attempts to FETCH the same failed mail more than once, the client is disconnected. This is to avoid clients from going into infinite loops trying to FETCH a broken mail.

imap: Track how much time was spent on waiting for locks.

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

imap: Include sync timing information in tagged command replies. Show it only when it's larger than 0 to avoid unnecessary output.

imap: Added struct client_command_context.tagline_reply Can be used by plugins.

imap: Made LDA settings accessible from plugins. This way, plugins can also send mail.

imap: Added assert to make sure client_command_context isn't freed too early.

imap: Added extra assert checks to make sure command states are consistent.

imap: If client disconnects, log the in-progress commands' input/output bytes.

imap: Improved command timing information reporting. We now report also the time we spent waiting on ioloop. Also fixed reporting command timing information when multiple commands were running in parallel (e.g. SEARCH + FETCH). If multiple commands are running in parallel they all report the same ioloop wait time, because there's no easy way to know which one of them caused the wait.

Added imap-hibernate process for gathering IDLEing imap processes. imap_hibernate_timeout setting controls how quickly the connection is moved from imap process to imap-hibernate process. Some IMAP extensions like NOTIFY, SEARCH=CONTEXT and COMPRESS aren't supported yet. There's also a new X-STATE command, which can be used to export the current IMAP connection state to a string and later on imported to get back to the original state (a quick resync feature for IMAP clients). However, this command is disabled for now due to the current code being unoptimized for untrusted input.

imap: Added %{deleted}, %{expunged} and %{trashed} to imap_logout_format

Added %{fetch_hdr/body_count/bytes} variables to imap_logout_format

imap: Include in tagged reply how much running time each IMAP command takes. The running time doesn't include time spent waiting for the client on ioloop.

imap, pop3: Show user's proper log prefix when deinitializing users at exit.

imap: if mailbox has non-permanent modseqs, never send HIGHESTMODSEQ/MODSEQs.

imap: Added initial support for METADATA extension. For now this is enabled only when imap_metadata=yes setting is used. The setting will go away once the feature is complete. Also mail_attribute_dict must be set. TODO: - Metadata doesn't work for public namespaces. There should probably be a mail_attribute_public_dict setting for that. - There isn't any kind of quota or other limits - After ENABLE METADATA start sending untagged METADATA entries to clients - /shared/admin should probably return postmaster_address URL - Check if we handle ACLs correctly - RFC says that it SHOULD be possible to set METADATA entries to \NoSelect mailboxes. We probably will never allow this though.

imap: Removed unnecessary code.

Added support for IMAP URLAUTH and URLAUTH=BINARY extensions Extends imap service with URLAUTH and URLAUTH=BINARY support: - Adds new commands URLFETCH, GENURLAUTH and RESETKEY. Creates imap-urlauth service in src/imap-urlauth. Functionality common to both the imap and imap-urlauth services is located in src/lib-imap-urlauth. TODO: - use mailbox GUIDs instead of names - doveadm command to delete stale urlauth entries? - add delay when attempting to access nonexistent user - create urlauth-worker queue, similar to how indexer-worker works (could we share code?..)

imap: Added asserts to make sure a tagline isn't sent twice to the same command.

imap: Fixed command output locking.

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

imap: Implemented NOTIFY extension. Requires mailbox_list_index=yes to work (and to show up in capabilities). SubscriptionChange event is still unimplemented.

Make sure we check all the functions' return values. Minor API changes to simplify this. Checked using a patched clang that adds attribute(warn_unused_result) to all functions. This commit fixes several error handling mistakes.

Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786

imap: Rewrote FETCH command to use imap-msgpart API.

Added a "session ID" string for imap/pop3 connections, available in %{session} variable. The session ID passes through Dovecot IMAP/POP3 proxying to backend server. The same session ID is can be reused after a long time (currently a bit under 9 years).

imap: Made client_destroy() a virtual method.

imap: Moved partial fetch cache from static variable into struct client.

imap: Fixed infinite loop / memory eating with SEARCHRES + pipelining $. If SEARCH RETURN (SAVE) command was running long enough so that Dovecot started executing the next command, and if that command used $ in messageset, Dovecot went into infinite function recursion.

lib-storage: Moved some items from mailbox_get_status() to a new mailbox_get_metadata(). The idea is now that all status items are tracked all the time after mailbox is opened and they can always be looked up without failure. The metadata items are looked up lazily and the lookups may fail at any time. mailbox_get_status() can be used after mailbox_alloc() to indicate that the mailbox doesn't necessarily have to be opened, just that the status fields get returned. If mailbox is already known to be open, mailbox_get_open_status() can be used. It never fails.

imap, pop3: Removed previous log prefix hack.

imap, pop3: Try to use the correct log prefix when service_count!=1.
