lib-master: Add stats-client Enable it if MASTER_SERVICE_FLAG_SEND_STATS is set

lib-master: master_service_init_log() - Switch log handlers only on the first call The secondary calls were only done by mail_storage_service_*() calls. They want to initialize the logging once, but afterwards they only care about changing the log prefix. Switch to this behavior now explicitly. This fixes behavior if logging functions are changed between mail_storage_service_*() calls, so they don't get reset.

lib-master: Replace listeners with /dev/null in SIGQUIT instead of closing This should be somewhat safer.

lib-master: master_service_init_finish() now verifies that t_pop() wasn't leaked

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

lib-master: Added support for HAProxy protocol. Patch by Stephan Bosch - with some small changes.

master: Changed passing of listener settings from master to process to be more flexible. This is needed to allow adding new listener settings, such as `haproxy'. Patch by Stephan Bosch - with some small changes.

lib-master: Moved connection accepting code to its own functions. No functional changes.

lib-master: Earlier config file path fix broke reusing existing config socket lookups.

lib-master: Added master_service_get_process_min_avail()

Read SSL settings only if service has SSL sockets or MASTER_SERVICE_FLAG_USE_SSL_SETTINGS.

Moved ssl_* settings from login-common to lib-master. This allows creating other SSL servers more easily.

lib-master: Added -i parameter to read config by instance name rather than path.

lib-master: Send service's idle_kill value to process in environment.

Listener names are now in struct master_service_connection.name This allows service to use the names to figure out what type the listener is.

lib-master: Added master_service_set_idle_die_callback()

master process now tells its children their service's process_limit.

doveadm: Added client/server architecture support for running mail commands. This is done when doveadm_worker_count is non-zero.

lib-master: Try to send master status more reliably. --HG-- branch : HEAD

lib-master: Changed post-login process's client counting to make sense again. This should also fix problems where a new process isn't created because an existing one is waiting for auth request reply. --HG-- branch : HEAD

lib-master: Avoid sending status updates to master too often. --HG-- branch : HEAD

lib-master: Make sure IO listeners aren't added back while doing auth lookup. --HG-- branch : HEAD

lib-master: When executing standalone, try first to read config from global socket. --HG-- branch : HEAD

imap, pop3: Close auth/config connections when we stop accepting more connections. --HG-- branch : HEAD

lib-master: Added master_service_stop_new_connections(). --HG-- branch : HEAD

lib-master: Fixes to handling master-login services. --HG-- branch : HEAD

imap, pop3: Connection counting fixes. Multiple real connections can come from "login connections". For now don't even try to count login connections. --HG-- branch : HEAD

Handle shutdown_clients globally for all services. Delay shutting down processes until it's convenient for them, but if they're not gone in 30 seconds forcibly stop. And if that doesn't help, master will start killing them in 60 seconds. --HG-- branch : HEAD

Moved most of getopt() handling to lib-master. --HG-- branch : HEAD

Redesigned how login process passes connections to mail processes and changed related APIs. Master process is no longer in the middle. --HG-- branch : HEAD

lib-master: Added _NO_CONFIG_SETTIGS and _NO_ENV_SETTINGS flags. --HG-- branch : HEAD

*-login: Fixed dropping oldest connection when reaching all limits. --HG-- branch : HEAD

lib-master: Added master_service_set_die_with_master. --HG-- branch : HEAD

lib-master: Added -O parameter to use program default settings. --HG-- branch : HEAD

lib-master: Added support for keeping config connection open and reusing it for later requests. --HG-- branch : HEAD

Binaries now take -o key=value parameters to override settings. --HG-- branch : HEAD

inet_listeners now support ssl=yes. For now only login processes support it. --HG-- branch : HEAD

Initial commit for v2.0 master rewrite. Several features are still missing. --HG-- branch : HEAD

Added lib-master and mail-storage-service code that makes it easier to build new Dovecot binaries. Currently only the standalone applications (e.g. deliver) uses this. --HG-- branch : HEAD
