lib-master: Add master_service_init_stats_client() This allows initializing the stats client after master_service_init() if necessary.

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

lib-master: Load SSL module if wanted by service

lib-master: Support HAproxy TLVs This allows passing in information about SSL and client certificate(s) and other information from haproxy.

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.

master: Move master_set_import_environment() to lib-master

lib-master: Add comments to struct master_service_connection

lib-master: Add automatic data stack frame to init unless disabled.

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

lib-master: master_service_is_master_stopped() now returns FALSE if running standalone. The only caller of this function was stats plugin to see if it should send stats updates. So this fixes dovecot-lda, doveadm and other standalone tools to send stats updates.

Changed type of internet port values to in_port_t everywhere. Created special SET_IN_PORT setting type for internet port values. Created net_str2port() for parsing internet port values. Removed several atoi() invocations in the process.

lib-master: Added local and real IP addresses and ports to struct master_service_connection.

lib-master: Make sure we can't accidentally add duplicate getopt args.

lib-master: Added master_service_get_socket_name()

lib-master: If MASTER_SERVICE_FLAG_KEEP_CONFIG_OPEN is set, open the config socket before dropping privileges.

Call master_service_init_finish() only after all of the initialization is done. This way if the init crashes, the master process will throttle a buggy service.

lib-master: Added master_service_is_master_stopped()

lib-master: Added master_service_get_process_min_avail()

Compiling fix for Solaris

lib-master: include unistd.h for master_getopt() users.

lib-master: Added version_string_verify_full()

login: Don't fail at startup by trying to load SSL plugin.

Renamed network.[ch] to net.[ch]. The function prefixes already started with net_ instead of network_. And icecap wants to use network.h for other purpose. :)

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

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

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_client_connection_created()

lib-master: Added master_service_set_idle_die_callback()

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

Added import_environment setting. This also cleans up different places in code where TZ and other environments are preserved. If it's not in the import_environment setting, it's not preserved.

lib-master: Added MASTER_SERVICE_FLAG_UPDATE_PROCTITLE for showing number of connections in ps. The title is still only updated if verbose_proctitle=yes, so this allows binaries to easily just set the flag and lib-master handles the rest.

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

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

Added version_string_verify() and removed code duplication with it. --HG-- branch : HEAD

lib-master API changed to avoid accidentally leaking client connections. This change also fixes many such leaks. --HG-- branch : HEAD

lib-master: Environment variables no longer override settings. Also did some other cleanups to settings reading and removed unused features. --HG-- branch : HEAD

lib-master: Added master_service_stop_new_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 process title init to lib-master. With Linux-hack enabled it now preserves command args. --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

Removed mail_log_max_lines_per_sec setting and related code. It's pretty unnecessary and there's really no good way to implement it with shared log pipes. --HG-- branch : HEAD

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

lib-master: Fixes to handling FIFO connections. Also expose the FIFOness to caller. --HG-- branch : HEAD

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

lib-master has now a global master_service variable that all binaries use. There should always be only one of them anyway. --HG-- branch : HEAD

master process shouldn't log to stderr. Changed the lib-master flag to _DONT_LOG_TO_STDERR. --HG-- branch : HEAD

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

Implemented anvil service, which is used to implement mail_max_userip_connections. --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

doveadm: Log to stderr. --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
