process managing message reception, delivery and transfer. Mostly
mechanical, but very intrusive as it required to rewamp all IMSG to

in the scheduler when it has too many tasks for a given relay. The
envelopes are put on a wait queue, and are not scheduled again until
the mta "releases" some envelopes from that queue.
It prevents from having too many inflight envelopes, which are out of reach
for the admin.

- parse the whole input before trying to establish the connection
to the local socket: fixes timeout problems when reading the output
of a long running program.
- use sendmail(8)-like exit status.
|
|
When sending a request to the scheduler, wait for the success/failure
report from the scheduler. Simplify the code by introducing generic
functions for interruptible iteration over envelopes. Report the total
number of affected envelopes for schedule, pause, resume and remove
envelope operations.
|
|
- Better transient error handling logic: failing destinations are
automatically disabled for a while. When a destination is active
again, ask the scheduler to retry previous envelopes immediatly.
- More informative error report when all routes fail for a mail.
- Implement a "smtpctl show hoststats" command to get the latest stat
message per MX domain.
- Implement a "smtpctl show routes" command to show the state the
currently known routes to remote MXs.
- Implement a "smtpctl resume route" command to re-enable a route that
has been disabled.
- Do not hardcode limits
- Minor code improvements
|
|
- implement suspend/resume scheduling for individual envelopes or message,
with the associated smtpctl commands.
- allow the mta to request immediate scheduling of an envelope.
- on temporary failures a penalty can be given to further delay the next try.

- replace "users" keyword with "userbase" when providing alternate userbase
- disambiguise expansion nodes when expanding across domains and userbases
- allow use of '=' instead of '=>' when declaring a mapping

* first bricks of ldap and sqlite support (not finished but both working)
* new table API to replace map API, all lookups are done through tables
* improved handling of temporary errors throughout the daemon
* improved scheduler and mta logic: connection reuse, optimizes batches
* improved queue: more tolerant to admin errors, new layout, less disk-IO
* improved memory usage under high load
* SSL certs/keys isolated to lookup process to avoid facing network
* VIRTUAL support improved, fully virtual setups possible now
* runtime tracing of processes through smtpctl trace
* ssl_privsep.c sync-ed with relayd
* ssl.c no longer contains smtpd specific interfaces
* smtpd-specific ssl bits moved to ssl_smtpd.c
* update mail address in copyright

is running. The scheduler sends the runtime state of each envelope to
the queue process which loads the envelope, fills the runtime bits and
sends the envelope back to the client. Iteration over the envelope set
happens in small chunks to make the request interruptible and to allow
the server to keep doing its job in the meantime.
Adpat "smtpctl schedule-all" to schedule the messages one by one using
the same iteration mechanism.
Document "smtpctl monitor" and "smtpctl show queue".

the server is running, and flush()/next_message() helpers to make

* Log more events (especially client session) and use a better scheme
for that: each messages is prefixed with a token to easily identify
its class:
- info/warn/debug: general server messages
- smtp-in: smtp client connections
- relay: status update for relayed messages
- delivery: status update for local deliveries
* Implement "smtpctl monitor" to display updates of selected internal
counters.
* When reloading the on-disk queue at startup do not commit a message
if no envelope was submitted for that message.
* Remove unused stuff in the config parser.

The idea is to have a file-backed map but to have smtpd(8) cache the maps
so that it cannot be partially read if edited while mail is received. The
file is read and converted to a static map (map_static.c), changes aren't
visible to smtpd until an explicit: smtpctl update map which reads file,
builds a new static map and invalidates the former.

this allows an admin to inspect the queue without having to manually
extract bucket and find the path to an envelope or message.

Ignore it in existing envelopes until it gets completely dropped.
Change "smtpctl show queue" to display the address family of the
envelope source instead of the ENQUEUE flag.

- remove SHOW_RUNQUEUE it was a noop since runqueues have been removed
years ago from smtpd
|
|
- statistics can now have a type (counter, timestamp, timeval, timespec and
possibly others in the future)
- stat_increment() / stat_decrement() now take an increment/decrement value
and are at the moment only of type counter
- stat_set() now takes a stat_value
- provide helpers to convert raw values to stat_value

while at it fix a rq_queue_dump() call using a bogus timestamp in scheduler
ramqueue.

> statistics are no longer static structures in shared memory
> statistics are only set, smtpd never uses them in its logic
> each statistic is a key/value where key can be any (dynamic) string
- convert all uses of the former API to use the new one
- implement stat_ramstat that keeps non-persistent stats in ram structure

- introduce scheduler_backend which does the same to scheduler than
queue_backend does to queue and map_backend does to maps
- remove all occurences of RUNNER and runner, replace them with SCHEDULER
and scheduler

Add a command-line option to specify the backend to use at runtime.

sanity checks and do not touch directories. A running server no

notify the runner of what happened with an envelope that has been
scheduled. It is not part of the state of the envelope, and it is not
even dumped. So it should only be set by mta/mda, checked by runner
to decide what to do with the envelope, and ignored everywhere else.
