Edit
Use the debuginfo file for debugging
Change description
From v2.5 onwards, the debuginfo file of BE is stripped from the StarRocks installation package to reduce the size and space usage of the installation package. You can see two packages at StarRocks website.
In this figure, you can click Get Debug Symbol files to download the debuginfo package. StarRocks-2.5.10.tar.gz is the installation package and you can click Download to download this package.
This change does not affect your download behavior or use of StarRocks. You can download only the installation package for cluster deployment and upgrade. The debuginfo package is only for developers to debug programs using GDB.
Precautions
GDB 12.1 or later is recommended for debugging.
How to use the debuginfo file
Download and decompress the debuginfo package.
wget https://releases.starrocks.io/starrocks/StarRocks-<sr_ver>.debuginfo.tar.gz tar -xzvf StarRocks-<sr_ver>.debuginfo.tar.gzNOTE
Replace
<sr_ver>with the version number of the StarRocks installation package you want to download.Load the debuginfo file when you perform GDB debugging.
- Method 1
objcopy --add-gnu-debuglink=starrocks_be.debug starrocks_beThis operation associates the debug info file with your executable file.
- Method 2
gdb -s starrocks_be.debug -e starrocks_be -c `core_file`
The debuginfo file works well with perf and pstack. You can directly use perf and pstack without additional operations.
