Hacker_zKg8MmGa · 2020 年3 月 17 日 06:10

这个问题在 tikv GitHub issue #11963 及 #5572 都有提及;

本质原因：

在 tikv readme 的 build issue 中有介绍，为了优化编译时间，仅仅包含的行号等信息，并非全部 debug 需要的信息。

解决效果：

要么编译时，debug = true ，要么 RUSTFLAGS=-Cdebuginfo=2 cargo build；
Debug 效果如下：

您好，我这边在debug的时候出现如下错误，这个您遇到过吗

jansu-dev · 2022 年2 月 18 日 04:05

这是稳定浮现的吗？

我没遇到过，可以格式化下报错信息

每次都出现，下边是格式化的报错信息

这个是不是得原厂的人来回复一下，感觉没看懂报的是啥意思

可以来这里聊一下,开发者论坛.https://internals.tidb.io/

TiDBer_NtDbUm7p · 2022 年2 月 22 日 02:21

开发者有专门的论坛？任何人都可以参与吗？

迪迦奥特曼 · 2022 年2 月 22 日 02:36

这个我提过，没人回答

atidat · 2022 年9 月 2 日 16:10

hello tikv vscode remote debug 的 launch.json 方便共享看下吗
