Question

我正在尝试创建一个包含三个元素的结构数组。在部署合同时运行此代码时，有时中间的鱼会以某种方式被最后一条鱼覆盖。然后我们观察到fishies数组变为长度为2而不是3。在观察Release事件时，我们会看到两个版本具有相同的fishId。

在松露迁移中部署的javascript代码如下所示：

module.exports = function(deployer, network, accounts) {
  const coo = accounts[0];
  deployer.then(async() => {
    let fishery = await Fishery.deployed();
    await Fishery.releaseFish(1, 1, 200, AUCTION_DURATION);
    await Fishery.releaseFish(2, 1, 200, AUCTION_DURATION);
    await Fishery.releaseFish(3, 1, 300, AUCTION_DURATION);
  });
};

定义结构和函数的可靠性代码如下所示：

Fish[] fishies;

function releaseFish(
    uint128 _id,
    uint32 _category,
)
    returns (uint)
{
    Fish memory _fish = Fish({
        id: _id,
        category: _category
    });

    uint256 newFishId = fishies.push(_fish) - 1;
    Release(
        newFishId,
        uint128(_id),
        uint32(_category)
    );
}

发布活动时会发生重复的fishId = 1事件。

Release(0,1,1)
Release(1,2,1)
Release(1,3,1)

或详细说明：

   },

不幸的是，这并非完全一致。在不同的计算机上运行它，有不同的安排，或者只是随机地运行它。

请注意，我已经从实际代码中简化了一点 - 但我希望它能够捕获讨论该问题的必要元素。

系统：在Ganache上运行松露迁移，每个的事务都出现在不同的块上。
