Subject: [Tarantool-patches] [PATCH v4 0/3] gc/xlog: delay xlog cleanup until relays are subscribed
Date: Wed, 24 Mar 2021 19:37:56 +0300	[thread overview]
Message-ID: <20210324163759.1900553-1-gorcunov@gmail.com> (raw)

Take a look please.

v2:
 - rebase code to the fresh master branch
 - keep wal_cleanup_delay option name
 - pass wal_cleanup_delay as an option to gc_init, so it
   won't be dependent on cfg engine
 - add comment about gc_delay_unref in plain bootstrap mode
 - allow to setup wal_cleanup_delay dynamically
 - update comment in gc_wait_cleanup and call it conditionally
 - declare wal_cleanup_delay as a double
 - rename gc.cleanup_is_paused to gc.is_paused and update output
 - do not show ref counter in box.info.gc() output
 - update documentation
 - move gc_delay_unref inside relay_subscribe call which runs
   in tx context (instead of relay's context)
 - update tests:
   - add a comment why we need a temp space on replica node
   - use explicit insert/snapshot operations
   - shrkink the number of insert/snapshot to speedup testing
   - use "restart" instead of stop/start pair
   - use wait_log helper instead of own function
   - add is_paused test
v3:
 - fix changelog
 - rework box_check_wal_cleanup_delay, the replication_anon
   setting is considered only in box_set_wal_cleanup_delay,
   ie when config is checked and parsed, moreover the order
   of setup is set to be behind "replication_anon" option
   processing
 - delay cycle now considers deadline instead of per cycle
   calculation
 - use `double` type for timestamp
 - test update
   - verify `.is_paused` value
   - minimize number of inserts
   - no need to use temporary space, regular space works as well
   - add comments on why we should restart the master node
v4:
 - drop argument from gc_init(), since we're configuring delay
   value from load_cfg.lua script there is no need to read the
   delay early, simply start gc paused and unpause it on demand
 - move unpause message to main wait cycle
 - test update:
   - verify tests and fix replication/replica_rejoin since it waits
     for xlogs to be cleaned up too early
   - use 10 seconds for XlogGapError instead of 0.1 second, this is
     a common deadline value
