Tarantool 2.2.3

Release: v. 2.2.3 Date: 2020-04-20 Tag: 2.2.3-1-g98ecc90

2.2.3 is the last stable version of the 2.2 release series. The label stable means we have all planned features implemented and we see no high-impact issues.

This release resolves roughly 34 issues since the latest stable version. There may be bugs in less common areas, please feel free to file an issue at GitHub.

Please note, this release contains no new features.

Tarantool 2.x is backward compatible with Tarantool 1.10.x in binary data layout, client-server protocol and replication protocol.

Please upgrade using the box.schema.upgrade() procedure to unlock all the new features of the 2.x series.

  • fiber.storage is cleaned between requests, and can be used as a request-local storage. Previously fiber.storage could contain some old values in the beginning of an iproto request execution, and it needed to be nullified manually. Now the cleanup is unneeded (gh-4662).
  • tuple/space/index:update()/upsert() were fixed not to turn a value into an infinity when a float value was added to or subtracted from a float column and exceeded the float value range (gh-4701).
  • Fix potential execution abort when operating the system runs under heavy memory load (gh-4722).
  • Make RTREE indexes handle the out of memory error: before this fix, OOM during the recovery of an RTREE index resulted in segmentation fault (gh-4619).
  • Fix the error message returned on using an already dropped sequence (gh-4753).
  • Add cancellation guard to avoid WAL thread stuck (gh-4127).
  • Fix execution abort when memtx_memory and vinyl_memory are set to more than 4398046510080 bytes. Now an error message is returned (gh-4705).

  • Fix rebootstrap procedure not working in case replica itself is listed in box.cfg.replication (gh-4759).
  • Fix possible user password leaking via replication logs (gh-4493).
  • Refactor vclock map to be exactly 4 bytes in size to fit all 32 replicas regardless of the compiler used (https://github.com/tarantool/tarantool/commit/e5679980aa5f813553a95ab7d31f111dd0893df6).
  • Fix crash when the replication applier rollbacks a transaction (gh-4730, (gh-4776).
  • Local space operations are now counted in 0th vclock component. Every instance may have its own 0-th vclock component not matching others’. Local space operations are not replicated at all, even as NOPs (gh-4114).
  • Gc consumers are now ordered by their vclocks and not by vclock signatures. Only the WALS that contain no entries needed by any of the consumers are deleted (gh-4114).

  • json: :decode() doesn’t spoil instance’s options with per-call ones (when it is called with the second argument) (gh-4761).
  • Handle empty input for uri.format() properly (gh-4779).
  • os.environ() is now changed when os.setenv() is called (gh-4733).
  • netbox.self:call/eval() now returns the same types as netbox_connection:call/eval. Previously it could return a tuple or box.error cdata (gh-4513).
  • box.tuple.* namespace is cleaned up from private functions. box.tuple.is() description is added to documentation (gh-4684).
  • tarantoolctl rocks search: fix the --all flag (gh-4529).
  • tarantoolctl rocks remove: fix the --force flag (gh-3632).
  • libev: backport fix for listening for more then 1024 file descriptors on Mac OS (gh-3867).

  • Fix box.stat() behavior: now it collects statistics on the PREPARE and EXECUTE methods as expected (gh-4756).
  • The inserted values are inserted in the order in which they are given in case of INSERT into space with autoincrement (gh-4256).

  • When building Tarantool with bundled libcurl, link it with the c-ares library by default (gh-4591).

  • __pairs/__ipairs metamethods handling is removed since we faced the issues with the backward compatibility between Lua 5.1 and Lua 5.2 within Tarantool modules as well as other third party code (gh-4770).
  • Introduce luajit-gdb.py extension with commands for inspecting LuaJIT internals. The extension obliges one to provide gdbinfo for libluajit, otherwise loading fails. The extension provides the following commands:
    • lj-arch dumps values of LJ_64 and LJ_GC64 macro definitions
    • lj-tv dumps the type and GCobj info related to the given TValue
    • lj-str dumps the contents of the given GCstr
    • lj-tab dumps the contents of the given GCtab
    • lj-stack dumps Lua stack of the given lua_State
    • lj-state shows current VM, GC and JIT states
    • lj-gc shows current GC stats
  • Fix string to number conversion: current implementation respects the buffer length (gh-4773).
  • “FFI sandwich”(*) detection is introduced. If sandwich is detected
    while trace recording the recording is aborted. The sandwich detected while mcode execution leads to the platform panic.
  • luaJIT_setmode call is prohibited while mcode execution and leads to the platform panic.

(*) The following stack mix is called FFI sandwich:

Lua-FFI -> C routine -> Lua-C API -> Lua VM

This sort of re-entrancy is explicitly not supported by LuaJIT compiler. For more info see gh-4427.

  • Fix assertion fault due to triggered dump process during secondary index build (gh-4810).

  • Fix crashes at attempts to use -e and -l command line options concatenated with their values, like this: -eprint(100) (gh-4775).
  • Fix inability to upgrade from 2.1 if there was an automatically generated sequence (gh-4771).
  • Update libopenssl version to 1.1.1f since the previous one was EOLed (gh-4830).
