Sheepdog v1.0.2_rc0 released. See #355 for backported commits.

1.0.2 (release candidate)

IMPORTANT CHANGES:

  • Unlimited workqueue is now removed and changed to dynamic one. This is for sheep not to consume a huge amount of memory by creating new threads infinitely under heavy load, and to avoid being shot by OOM-killer.
  • zk_control now can purge znodes within 24 hours. It purges znodes created before the given threshold. This is useful if tens of thousands of znodes are created in a day.

SHEEP COMMAND INTERFACE:

  • New option "-x" to set the maximum number of threads for dynamic workqueue. (default: decided by "max(#nodes,#cores,16)*2" formula)

ZK_CONTROL COMMAND INTERFACE:

  • The "purge" subcommand can take a non-negative interger as a threshold in seconds. (default: 86400 (24 hours))

LOGGING:

  • Print object IDs in 16-digit zero-padded hexadecimal to sheep.log.

Sorry for being late. v1.0.2 is not released yet.

I found that v1.0.2_rc0 has a distributed deadlock issue like v0.9.5, as I mentioned in #354.

I can't make up my mind what I should do; just document it as a known issue or fix it by cherry-picking #362.
