----------------------------
Summary: Fix a bug about reading a zero-size map in the compact
protocol implementation to lua
Key: THRIFT-5263
URL: https://issues.apache.org/jira/browse/THRIFT-5263
Project: Thrift
Issue Type: Bug
Components: Lua - Library
Affects Versions: 0.13.0
Reporter: zero
bug in lib/lua/TCompactProtocol.lua, code as follow:
function TCompactProtocol:readMapBegin()
local size = self:readVarint32()
local kvtype = 0
if size > 0 then
kvtype = self:readSignByte()
end
local ktype = self:getTType(libluabitwise.shiftr(kvtype, 4))
local vtype = self:getTType(kvtype)
return ktype, vtype, size
end
if the map's size is zero, it should‘t read another byte.
