This patchset consists of following conceptual changes: 1. Func updates on alter were simplified: now replace _func tuple is forbidden and func_new constructor may fail. This makes possible to define a failable function object constructors. 2. box_lua_call and box_lua_eval were refactored to do nottake call_request argument and to use input and output port instead. A new msgpack_port allows to use this abstraction also for a regular memory msgpack. 3. Introduced an abstract function class and func_c and func_lua implementations that allow to call C and Lua functions correspondingly with uniform API defined on base func class. 4. Introduced an infrastructure to call functions from Lua. A new box.func folder exports functions objects that have :call and :drop methods and their definition. 4. Introduced persistent Lua functions. Such functions are a part of Tarantool snapshoot so they are available even after restart. The new is_sandboxed option initializes a new persistent Lua function is a separate 'sandbox': an isolated environment with strong restrictions: only limited number of on-board functions are available, no global state is available at all. Persistent Lua functions is an important step to implement functional indexes in Tarantool. Only a deterministic, sandboxed, persistent Lua function may be used as a functional index extractor. Changes in version 3: Source code is re-organised to be bit clear and to provide a better function object abstraction. http://github.com/tarantool/tarantool/tree/kshch/gh-4182-persistent-lua-functions https://github.com/tarantool/tarantool/issues/4182 Kirill Shcherbatov (6): box: rework func cache update machinery box: rework box_lua_{call, eval} to use input port box: rework func object as a function frontend box: export registered functions in box.func folder box: refactor box_lua_find helper box: introduce Lua persistent functions src/box/alter.cc | 111 ++++--- src/box/bootstrap.snap | Bin 4475 -> 4532 bytes src/box/call.c | 151 ++------- src/box/call.h | 4 - src/box/execute.c | 1 + src/box/func.c | 199 +++++++++-- src/box/func.h | 40 +-- src/box/func_def.c | 25 ++ src/box/func_def.h | 34 +- src/box/lua/call.c | 621 +++++++++++++++++++++++++++++++---- src/box/lua/call.h | 13 +- src/box/lua/execute.c | 7 +- src/box/lua/execute.h | 4 +- src/box/lua/init.c | 1 + src/box/lua/misc.cc | 10 +- src/box/lua/schema.lua | 41 ++- src/box/lua/upgrade.lua | 25 +- src/box/port.c | 3 +- src/box/port.h | 19 +- src/box/schema.cc | 38 +-- src/box/schema.h | 15 +- src/box/schema_def.h | 4 + src/box/session.cc | 11 +- src/box/session.h | 8 + src/lib/core/port.h | 15 +- test/box-py/bootstrap.result | 6 +- test/box/access_misc.result | 6 +- test/box/function1.c | 33 ++ test/box/function1.result | 332 +++++++++++++++++++ test/box/function1.test.lua | 115 +++++++ test/box/misc.result | 1 + 31 files changed, 1544 insertions(+), 349 deletions(-) -- 2.21.0
