Overview

This release adds functionality to the pool that prevents inappropriate use which can cause exit(1) or segmentation fault.

Breaking changes

There are no breaking changes in the release.

Changes

  • Forbid putting connections back to another pool (PR #68).

    local p1 = mysql.pool_create(pool_cfg)
local p2 = mysql.pool_create(pool_cfg)

local c = p1:get()
p2:put(c)

    will now result in error throw:

    ---
- error: 'Trying to put connection from pool table: 0x405b8868 to pool table: 0x40981288'
...

    Before this release, overflowing pool with put from other pool could result in application getting forever stuck or Tarantool process exit(1) because of fiber yield on garbage collect.

  • Close connection pool if queue overflowed on gc (PR #68).

    Queue overflow results in fiber yield on gc. Yielding in gc is prohibited since Tarantool 2.6.0-138-gd3f1dd720, 2.5.1-105-gc690b3337, 2.4.2-89-g83037df15, 1.10.7-47-g8099cb053. In previous versions yielding in gc resulted in undefined behavior for LuaJit traces compiler and could be the reason for segmentation faults.

Other

  • Publish rockspecs with CD on master update and new tags (PR #69).
