## Bug Fixes
@ -32,104 +31,57 @@
- [#10014](https://github.com/emqx/emqx/pull/10014) Ensure Monitor API `/monitor(_current)/nodes/:node` returns `404` instead of `400` if node does not exist.
- [#10026](https://github.com/emqx/emqx/pull/10026) Metrics are now only exposed via the /bridges/:id/metrics endpoint. Metrics are no longer returned in other API operations such as getting the list of all bridges, or in the response when a bridge has been created.
- [#10027](https://github.com/emqx/emqx/pull/10027) Allow setting node name from `EMQX_NODE__NAME` when running in docker.
Prior to this fix, only `EMQX_NODE_NAME` is allowed.
- [#10027](https://github.com/emqx/emqx/pull/10027) Allow setting node name via environment variable `EMQX_NODE__NAME` in Docker.
- [#10050](https://github.com/emqx/emqx/pull/10050) Ensure Bridge API returns `404` status code consistently for resources that don't exist.
- [#10052](https://github.com/emqx/emqx/pull/10052) Improve daemon mode startup failure logs.
Before this change, it was difficult for users to understand the reason for EMQX 'start' command failed to boot the node.
The only information they received was that the node did not start within the expected time frame,
and they were instructed to boot the node with 'console' command in the hope of obtaining some logs.
However, the node might actually be running, which could cause 'console' mode to fail for a different reason.
With this new change, when daemon mode fails to boot, a diagnosis is issued. Here are the possible scenarios:
* If the node cannot be found from `ps -ef`, the user is instructed to find information in log files `erlang.log.*`.
* If the node is found to be running but not responding to pings, the user is advised to check if the host name is resolvable and reachable.
* If the node is responding to pings, but the EMQX app is not running, it is likely a bug. In this case, the user is advised to report a Github issue.
- [#10055](https://github.com/emqx/emqx/pull/10055) The configuration parameter `mqtt.max_awaiting_rel` was not functional and has now been corrected.
- [#10056](https://github.com/emqx/emqx/pull/10056) Fix `/bridges` API status code.
- Return `400` instead of `403` in case of removing a data bridge that is dependent on an active rule.
- Return `400` instead of `403` in case of calling operations (start|stop|restart) when Data-Bridging is not enabled.

- [#10066](https://github.com/emqx/emqx/pull/10066) Improve error messages for `/briges_probe` and `[/node/:node]/bridges/:id/:operation` API calls to make them more readable. And set HTTP status code to `400` instead of `500`.
- [#10074](https://github.com/emqx/emqx/pull/10074) Check if type in `PUT /authorization/sources/:type` matches `type` given in body of request.

- [#10100](https://github.com/emqx/emqx/pull/10100) Fix channel crash for slow clients with enhanced authentication.
Previously, when the client was using enhanced authentication, but the Auth message was sent slowly or the Auth message was lost, the client process would crash.
- [#10100](https://github.com/emqx/emqx/pull/10100) Fix channel crash for slow clients with enhanced authentication.
Previously, when the client was using enhanced authentication, but the Auth message was sent slowly or the Auth message was lost, the client process would crash.
- [#10107](https://github.com/emqx/emqx/pull/10107) For operations on Bridges API if `bridge-id` is unknown we now return `404`
instead of `400`. Also a bug was fixed that caused a crash if that was a node
operation. Additionally we now also check if the given bridge is enabled when
doing the cluster operation `start` . Affected endpoints:
* [cluster] `/bridges/:id/:operation`,
* [node] `/nodes/:node/bridges/:id/:operation`, where `operation` is one of
`[start|stop|restart]`.
Moreover, for a node operation, EMQX checks if node name is in our cluster and
return `404` instead of `501`.
- [#10107](https://github.com/emqx/emqx/pull/10107) For operations on Bridges API if `bridge-id` is unknown we now return `404` instead of `400`.
- [#10117](https://github.com/emqx/emqx/pull/10117) Fix an error occurring when a joining node doesn't have plugins that are installed on other nodes in the cluster.

- [#10118](https://github.com/emqx/emqx/pull/10118) Fix problems related to manual joining of EMQX replicant nodes to the cluster.
Previously, after manually executing joining and then leaving the cluster, the `replicant` node can only run normally after restarting the node after joining the cluster again.
[Mria PR](https://github.com/emqx/mria/pull/128)
- [#10119](https://github.com/emqx/emqx/pull/10119) Fix crash when `statsd.server` is set to an empty string.
- [#10124](https://github.com/emqx/emqx/pull/10124) The default heartbeat period for MongoDB has been increased to reduce the risk of too excessive logging to the MongoDB log file.
- [#10130](https://github.com/emqx/emqx/pull/10130) Fix garbled config display in dashboard when the value is originally from environment variables.
For example, `env EMQX_STATSD__SERVER='127.0.0.1:8124' . /bin/emqx start` results in unreadable string (not '127.0.0.1:8124') displayed in Dashboard's Statsd settings page.

Prior to the fix, the command was not stopping `jq` and `os_mon` applications properly.
- [#10144](https://github.com/emqx/emqx/pull/10144) Add `-setcookie` emulator flag when invoking `emqx ctl` to prevent problems with emqx cli when home directory is read only. Fixes [#10142](https://github.com/emqx/emqx/issues/10142).
- [#10144](https://github.com/emqx/emqx/pull/10144) Fix an issue where emqx cli failed to set the Erlang cookie when the emqx directory was read-only.
- [#10154](https://github.com/emqx/emqx/pull/10154) Change the default `resume_interval` for bridges and connectors to be
the minimum of `health_check_interval` and `request_timeout / 3`.
Also exposes it as a hidden configuration to allow fine tuning.
- [#10154](https://github.com/emqx/emqx/pull/10154) Change the default `resume_interval` for bridges and connectors to be the minimum of `health_check_interval` and `request_timeout / 3` to resolve issue of request timeout.
Before this change, the default values for `resume_interval` meant
that, if a buffer ever got blocked due to resource errors or high
message volumes, then, by the time the buffer would try to resume its
normal operations, almost all requests would have timed out.
- [#10157](https://github.com/emqx/emqx/pull/10157) Fixed default rate limit configuration not being applied correctly when creating a new listener.
- [#10157](https://github.com/emqx/emqx/pull/10157) Fix default rate limit configuration not being applied correctly when creating a new listener.
- [#10237](https://github.com/emqx/emqx/pull/10237) Ensure we return `404` status code for unknown node names in `/nodes/:node[/metrics|/stats]` API.
- [#10251](https://github.com/emqx/emqx/pull/10251) Consider bridges referenced in `FROM` rule clauses as dependencies.
Before this fix, when one tried to delete an ingress rule referenced in an action like `select * from "$bridges/mqtt:ingress"`, the UI would not trigger a warning about dependent rule actions.
- [#10251](https://github.com/emqx/emqx/pull/10251) Fix an issue where rule dependencies were not prompted when deleting an ingress-type bridge in use.
- [#10313](https://github.com/emqx/emqx/pull/10313) Ensure that when the core or replicant node starting, the `cluster-override.conf` file is only copied from the core node.
Previously, when sorting nodes by startup time, the core node may have copied this file from the replicant node.
- [#10314](https://github.com/emqx/emqx/pull/10314) Fix /monitor_current API so that it only looks at the current node.
Fix /stats API to not crash when one or more nodes in the cluster are down.
- [#10327](https://github.com/emqx/emqx/pull/10327) Don't increase “actions.failed.unknown” rule metrics counter upon receiving unrecoverable data bridge errors.
- [#10327](https://github.com/emqx/emqx/pull/10327) Don't increment 'actions.failed.unknown' rule metrics counter upon receiving unrecoverable bridge errors.
This counter is displayed on the dashboard's rule overview tab ('Action statistics' - 'Unknown').
The fix is only applicable for synchronous bridges, as all rule actions for asynchronous bridges
are counted as successful (they increment 'actions.success' which is displayed as 'Action statistics' - 'Success').
- [#10095](https://github.com/emqx/emqx/pull/10095) Stop MySQL client from bombarding server repeatedly with unnecessary `PREPARE` queries on every batch, trashing the server and exhausting its internal limits. This was happening when the MySQL bridge was in the batch mode.
Ensure safer and more careful escaping of strings and binaries in batch insert queries when the MySQL bridge is in the batch mode.
- [#10095](https://github.com/emqx/emqx/pull/10095) Fix an issue where when the MySQL connector was in batch mode, clients would keep querying the server with unnecessary `PREPARE` statements on each batch, possibly causing server resource exhaustion.

- [#10139](https://github.com/emqx/emqx/pull/10139) 将 `extraVolumeMounts` 添加到 EMQX Helm Chart 中，它将能够挂载用户自己的文件到 EMQX 实例中，例如在 [#9052](https://github.com/emqx/emqx/issues/9052) 中提到的 ACL 规则文件。
修复了 issue [#10116](https://github.com/emqx/emqx/issues/10116)
- [#10139](https://github.com/emqx/emqx/pull/10139) 在 EMQX Helm Chart 中添加 `extraVolumeMounts`，可以挂载用户自己的文件到 EMQX 实例中，例如在 [#9052](https://github.com/emqx/emqx/issues/9052) 中提到的 ACL 规则文件。
- [#9893](https://github.com/emqx/emqx/pull/9893) 当使用 `clean_start=false` 标志连接时，EMQX 将会从消息队列中过滤出被封禁客户端发出的消息，使它们不能被下发给订阅者。
此前被封禁客户端发出的消息仍可能在这一场景下被下发给订阅者。
- [#9893](https://github.com/emqx/emqx/pull/9893) 当使用 `clean_start=false` 标志连接时，EMQX 将过滤掉会话中被被黑名单功能禁止的客户端发布的消息。以前，在这种情况下，被黑名单功能禁止的客户端发送的消息仍可能被传递给订阅者。

- [#9881](https://github.com/emqx/emqx/pull/9881) 增强了与 InfluxDB 连接健康检查相关的错误日志。
在此更改之前，如果使用配置的参数 InfluxDB 未能通过健康检查，用户仅能获得一个“超时”的信息。
现在，详细的错误消息将显示在日志和控制台，从而让用户更容易地识别和解决问题。
- [#10123](https://github.com/emqx/emqx/pull/10123) 改进了 `/bridges` API 的性能。避免了当集群节点数量较多时可能出现的请求响应超时。
- [#10123](https://github.com/emqx/emqx/pull/10123) 改进 `/bridges` API 的性能。
此前，当集群中节点数目较多或节点忙时，该 API 可能出现请求超时的情况。
- [#9998](https://github.com/emqx/emqx/pull/9998) 出于安全原因，在使用 HTTP 服务进行客户端认证时，对错误日志中的请求体进行脱敏处理。
- [#9998](https://github.com/emqx/emqx/pull/9998) 出于安全原因，在身份验证错误日志中模糊 HTTP 请求正文。
- [#10026](https://github.com/emqx/emqx/pull/10026) 仅在 `/bridges/:id/metrics` API 中返回指标数据。

## 修复
- [#10013](https://github.com/emqx/emqx/pull/10013) 修复 API `/gateways/:name/clients` 返回值的类型结构错误。
- [#10013](https://github.com/emqx/emqx/pull/10013) 修复 `/gateways/:name/clients` API 在错误情况下的返回类型结构。
- [#10014](https://github.com/emqx/emqx/pull/10014) 如果 API 查询的节点不存在，将会返回 `404` 而不再是 `400`。
- [#10014](https://github.com/emqx/emqx/pull/10014) 当节点不存在时，`/monitor(_current)/nodes/:node` API 返回 `404` 错误代码而不是 `400` 。
- [#10026](https://github.com/emqx/emqx/pull/10026) 现在只有显式调用 `/bridges/:id/metrics` 接口时才可以获得指标数据，而其他 API 接口将不再返回相关数据。
- [#10027](https://github.com/emqx/emqx/pull/10027) 允许在 Docker 中通过 `EMQX_NODE__NAME` 设置节点名称。
- [#10027](https://github.com/emqx/emqx/pull/10027) 在 docker 中启动时，允许使用 `EMQX_NODE__NAME` 环境变量来配置节点名。
在此修复前，只能使 `EMQX_NODE_NAME`。
- [#10050](https://github.com/emqx/emqx/pull/10050) 当调用 Bridge API 时若资源不能存在则返回 `404` 状态码。
- [#10050](https://github.com/emqx/emqx/pull/10050) 确保 Bridge API 对不存在的资源一致返回 `404` 状态代码。

- [#10056](https://github.com/emqx/emqx/pull/10056) 修复 `/bridges` API 状态码返回错误。当被删除的 Bridge 存在依赖，或 Bridge 未启用时进行启用、停止、重启等操作时返回 `400` 状态码。
在进行此更改之前，当 EMQX 用 `start` 命令启动失败时，用户很难理解出错的原因。
所知道的仅仅是节点未能在预期时间内启动，然后被指示以 `console` 式引导节点以获取一些日志。
然而，节点实际上可能正在运行，这可能会导致 `console` 模式因不同的原因而失败。
- [#10066](https://github.com/emqx/emqx/pull/10066) 优化 `/briges_probe` 和 `[/node/:node]/bridges/:id/:operation` API 调用的错误消息，使其更易理解。并修正错误状态码为`400`。
此次修复后，启动脚本会发出诊断：
- [#10074](https://github.com/emqx/emqx/pull/10074) 增加 `PUT /authorization/sources/:type` 请求参数 `type` 的值与请求体中的实际类型的一致性检查。
* 如果无法从 `ps -ef` 中找到节点，则指示用户在 `erlang.log.*` 中查找信息。
* 如果发现节点正在运行但不响应 ping，则建议用户检查节点主机名是否有效并可达。
* 如果节点响应 ping 但 EMQX 应用程序未运行，则很可能是一个错误。在这种情况下，建议用户报告一个Github issue。
- [#10079](https://github.com/emqx/emqx/pull/10079) 修复文档中关于 `shared_subscription_strategy` 的描述错误。
- [#10055](https://github.com/emqx/emqx/pull/10055) 修复配置项 `mqtt.max_awaiting_rel` 更新不生效问题。

- 当删除被活动中的规则依赖的数据桥接时，将返回 `400` 而不是 `403` 。
- 当数据桥接未启用时，调用操作（启动|停止|重启）将返回 `400` 而不是 `403`。
- [#10098](https://github.com/emqx/emqx/pull/10098) 修复了当配置 MongoDB 授权时 MongoDB 连接器崩溃的问题。
- [#10066](https://github.com/emqx/emqx/pull/10066) 改进 `/briges_probe` 和 `[/node/:node]/bridges/:id/:operation` API 调用的错误信息，使之更加易读。并将 HTTP 状态代码设置为 `400` 而不是 `500`。
- [#10100](https://github.com/emqx/emqx/pull/10100) 修复了当客户端使用增强认证时，认证消息发送缓慢或者消息丢失时客户端进程崩溃的问题。
- [#10074](https://github.com/emqx/emqx/pull/10074) 检查 `PUT /authorization/sources/:type` 中的类型是否与请求正文中的 `type` 相符。
- [#10107](https://github.com/emqx/emqx/pull/10107) 当调用 `bridges API` 时如果 `bridge-id` 不存在则返回 `404` 状态码。
- [#10079](https://github.com/emqx/emqx/pull/10079) 修正对 `shared_subscription_strategy` 的描述。
- [#10117](https://github.com/emqx/emqx/pull/10117) 修复当加入的节点没有安装在集群其他节点上的插件时发生的错误。修复后，加入的节点将从其他节点复制所有必要的插件。
- [#10118](https://github.com/emqx/emqx/pull/10118) 修复手动添加 EMQX 副本类型节点到集群的相关问题。
- [#10085](https://github.com/emqx/emqx/pull/10085) 如果向 `/authorization/sources/:source[/*]` 请求的 `source` 不存在，将一致地返回 `404`。
- [#10119](https://github.com/emqx/emqx/pull/10119) 修复了当 `statsd.server` 设置为空字符串时会崩溃的问题。
- [#10098](https://github.com/emqx/emqx/pull/10098) 当 MongoDB 授权模块查询数据库时，在日志文件中发生的崩溃与错误已经被修复。
- [#10124](https://github.com/emqx/emqx/pull/10124) 调整 MongoDB 的默认心跳周期，以降低日志文件记录过多的风险。
- [#10100](https://github.com/emqx/emqx/pull/10100) 修复响应较慢的客户端在使用增强认证时可能出现崩溃的问题。
此前，当客户端使用增强认证功能，但发送 Auth 报文较慢或 Auth 报文丢失时会导致客户端进程崩溃。
- [#10130](https://github.com/emqx/emqx/pull/10130) 修复了通过环境变量设置的值，在 Dashboard 中显示乱码的问题。
- [#10107](https://github.com/emqx/emqx/pull/10107) 现在对桥接的 API 进行调用时，如果 `bridge-id` 不存在，将会返回 `404`，而不再是`400`。
然后，还修复了这种情况下，在节点级别上进行 API 调用时，可能导致崩溃的问题。
另外，在启动某个桥接时，会先检查指定桥接是否已启用。
受影响的接口有：
* [cluster] `/bridges/:id/:operation`,
* [node] `/nodes/:node/bridges/:id/:operation`,
