Node-redis: `get`上的数据损坏

在get上发现了奇怪的数据损坏。

在Docker +节点版本6.3.0和5.12.0中尝试使用最新的redis：3和redis：2 。
试图将redis软件包版本一分为二，发现该错误已在2.6.0版本中引入。

测试重现：

const assert = require('assert');

const redis = require('redis').createClient();

const data = JSON.stringify({
    "city_name": "Санкт-Петербург" // (russian language)
});
const key = 'somekey';

describe('redis', () => {

    before(done => redis.set(key, data, done));
    after(done  => redis.del(key, done));

    for (let i = 0; i < 10000; ++i) {
        it(`pass ${i}`, done => {
            redis.get(key, (err, results) => {
                assert(!err);
                assert.strictEqual(results, data);

                done();
            });
        })
    }

});

package.json：

{
  "devDependencies": {
    "mocha": "^2.5.3"
  },
  "dependencies": {
    "redis": "=2.6.0"
  }
}

输出：

    ... (skipped)
    ✓ pass 1217
    ✓ pass 1218
    1) pass 1219
    2) "after all" hook

  1219 passing (4s)
  2 failing

  1) redis pass 1219:

      Uncaught AssertionError: '{"city_name":"��анкт-Петербург"}' === '{"city_name":"Санкт-Петербург"}'
      + expected - actual

      -{"city_name":"��анкт-Петербург"}
      +{"city_name":"Санкт-Петербург"}

失败的通行证号码是浮动的。 Mocha运行时带有-b标志以在第一次失败时停止，但是如果我们在没有此标志的情况下对其进行测试，则它将在第一次通过失败后继续失败：

    ... (skipped)
    ✓ pass 2477
    ✓ pass 2478
    1) pass 2479
    2) pass 2480
    3) pass 2481
    4) pass 2482
    5) pass 2483
    ... (all passes are failed until the end)

第一个失败与数据损坏有关，第二个失败与回调中的err有关：

或有时与此：

     Uncaught RangeError: out of range index
      at RangeError (native)
      at concatBuffer (node_modules/redis-parser/lib/parser.js:357:13)

不能仅使用拉丁字符进行复制。 也无法使用return_buffers: true复制。

这是通过redis-cli ，也许会有所帮助：

127.0.0.1:6379> get somekey
"{\"city_name\":\"\xd0\xa1\xd0\xb0\xd0\xbd\xd0\xba\xd1\x82-\xd0\x9f\xd0\xb5\xd1\x82\xd0\xb5\xd1\x80\xd0\xb1\xd1\x83\xd1\x80\xd0\xb3\"}"
