编辑设计文档并设置 update_notification 时出错
Errors when a design document is edited and an update_notification is set
我在 Ubuntu 16.04 上安装了 CouchDB 2.0，运行，单节点。我的应用程序的一个特定方面具有写入繁重的负载，但我希望读取需要及时，因此我希望使用 update_notification 在每次 n 写入时重建索引。
我创建了一个小型 NodeJS 应用程序来处理这个问题，但发现每次编辑设计文档时，我的服务器都会崩溃。结果证明这是因为 CouchDB 启动了数百个更新侦听器副本，而这又似乎是因为 couch.log 中报告的崩溃。每次发生崩溃时，都会生成一个新的更新侦听器，但旧脚本不会终止。
我已将其简化为一个简单的案例，其中 update_notification 处理程序实际上什么都不做，只是记录它从 STDIN:
收到的更新
updates.bash:
#!/bin/bash
while read -r line
do
echo "$line" >> /home/www/logs/updates.log
done
local.ini:
[update_notification]
updates=/home/www/updates.bash
我希望看到 updates.log 充满通知，例如...
{"type":"updated","db":"transactions"}
{"type":"ddoc_updated","db":"transactions","id":"_design/temp"}
... 这就是在 CouchDB 1.6.1 上看到的。但是在 CouchDB 2.0 上，我看到我的 couch.log 填充了数百个崩溃报告，并且我的更新脚本反复重新生成。

我想我对 update_notification 的工作原理做出了一些糟糕的假设，但对于我来说，我不知道那会是什么？这也是一个难以调试的问题，因为错误有些不透明，即使是我能想出的最简单的 update_notification 脚本仍然表现出这种行为。
有人知道我做错了什么吗？
您发现了一个非常古老的 API，它在 CouchDB 1.0 前后已退役，取而代之的是：
我在 Ubuntu 16.04 上安装了 CouchDB 2.0，运行，单节点。我的应用程序的一个特定方面具有写入繁重的负载，但我希望读取需要及时，因此我希望使用 update_notification 在每次 n 写入时重建索引。
我创建了一个小型 NodeJS 应用程序来处理这个问题，但发现每次编辑设计文档时，我的服务器都会崩溃。结果证明这是因为 CouchDB 启动了数百个更新侦听器副本，而这又似乎是因为 couch.log 中报告的崩溃。每次发生崩溃时，都会生成一个新的更新侦听器，但旧脚本不会终止。
我已将其简化为一个简单的案例，其中 update_notification 处理程序实际上什么都不做，只是记录它从 STDIN:
updates.bash:
#!/bin/bash
while read -r line
do
echo "$line" >> /home/www/logs/updates.log
done
local.ini:
[update_notification]
updates=/home/www/updates.bash
我希望看到 updates.log 充满通知，例如...
{"type":"updated","db":"transactions"}
{"type":"ddoc_updated","db":"transactions","id":"_design/temp"}
... 这就是在 CouchDB 1.6.1 上看到的。但是在 CouchDB 2.0 上，我看到我的 couch.log 填充了数百个崩溃报告，并且我的更新脚本反复重新生成。
