Fluentd v1.12.2 has been released

Hi users!

We have released v1.12.2. ChangeLog is here.

out_copy: Add a new attribute ignore_if_prev_successes

You can start using ignore_if_prev_successes to define fallback outputs. Fluentd will make use of these destinations if (and only if) the preceding outputs failed.

<store ignore_error>
  @type test
  name c0
</store>
<store ignore_if_prev_success ignore_error>
  @type test
  name c1
</store>
<store ignore_if_prev_success>
  @type test
  name c2
</store>

time-format: Add a new option time_format_fallbacks

Fluentd is now able to handle a heterogeneous time field. For example, if your timestamp field is mostly unixtime, but sometimes formatted in iso8601, you can specify as follows:

time_type mixed
time_format_fallbacks unixtime, %iso8601

formatter_ltsv: Safe delimiter character handling

To prevent LTSV data from being corrupted, we've started to substitute a delimiter character in records with a safe replacement. You can fine-tune the behaviour using replacement option as follows:

<format>
  @type ltsv
  replacement " "
</format>

Several in_tail stability fixes

We’ve fixed several in_tail stability issues:

• in_tail may not send rotated logs when mv is used to rotate #3292
• in_tail crashes worker upon ENOENT #3274

out_forward: Fix duplication logs at shutdown

Fluentd now waits ack responses in the shutdown phase correctly #3137.
