Bring SNI behavior into better conformance with RFC 6066:

- no longer send a warning-level unrecognized_name(112) alert
  when no matching vhost is found (PR 56241)

<not backported to 2.2.x>
- at startup, only issue warnings about IP/port conflicts and name-based
  SSL vhosts when running with an OpenSSL without TLS extension support
  (almost 5 years after SNI was added to 2.2.x, the
  "[...] only work for clients with TLS server name indication support"
  warning feels obsolete)
</not backported to 2.2.x>

r979120 | rjung | 2010-07-25 23:08:15 +0200 (Sun, 25 Jul 2010) | 26 lines

Adding sub second timestamps and request end time to mod_log_config.

Add special format tokens to %{...}t. The extended syntax allows the
form: "WHICH:WHAT".

WHICH is either:
- "begin": use the time when the request started
- "end": take "now" as the time
You can omit WHICH, default is "begin".
If you omit WHICH, the separating column is not allowed.

WHAT is either:
- "sec": timestamp in Unix seconds
- "msec": timestamp in Unix milliseconds
- "msec_frac": millisecond fraction of the Unix timestamp,
               3 digits, 0-padded
- "usec": timestamp in Unix microseconds
- "usec_frac": microsecond fraction of the Unix timestamp
               6 digits, 0-padded
- anything different from those tokens: use strftime()
You can omit WHAT, default is the formatted timestamp as
used by the Common Log Format.

The implementation uses a new request_config for mod_log_config
to pass the request end time around between different calls to
log formatters, but the end time is only generated if needed.

This makes data consistent if a log format uses
multiple %{...}T and/or %D.
The end time of a request is only taken once and
the same time is used for each log field.

mod_log_config: Add %M format to output request duration in milliseconds.



r1680895 | rjung | 2015-05-21 17:07:15 +0200 (Thu, 21 May 2015) | 14 lines

mod_log_config: instead of using the new dedicated
pattern format "%M" for duration milliseconds,
overload the existing "%D" to choose the time precision
("%{s}D" for seconds, "%{ms}D" for milliseconds and
"%{us}D" for microseconds).

The existing %T and %D without precision are kept for
compatibility.

The previously introduced "%M" (r1677187) is removed,
it has not yet been released. Format pattern characters
are rare, so we should only use a new one if an
existing one isn't a good fit.
