18.104.22.168 Using WER with PDB to create a Windows crashdump
Program Database files (with suffix
pdb) are included in the ZIP Archive Debug Binaries & Test Suite distribution of MySQL. These files provide information for debugging your MySQL installation in the event of a problem. This is a separate download from the standard MSI or Zip file.
The PDB files are available in a separate file labeled "ZIP Archive Debug Binaries & Test Suite".
The PDB file contains more detailed information about
mysqld and other tools that enables more detailed trace and dump files to be created. You can use these with WinDbg or Visual Studio to debug mysqld.
To use WinDbg, either install the full Windows Driver Kit (WDK) or install the standalone version.
.pdb files must be an exact match (both version number and MySQL server edition) or WinDBG will complain while attempting to load the symbols.
To generate a minidump
mysqld.dmp, enable the
core-fileoption under the [mysqld] section in
my.ini. Restart the MySQL server after making these changes.
Create a directory to store the generated files, such as
Determine the path to your windbg.exe executable using the Find GUI or from the command line, for example:
dir /s /b windbg.exe-- a common default is C:\Program Files\Debugging Tools for Windows (x64)\windbg.exe
windbg.exegiving it the paths to
mysqld.dmp, and the source code. Alternatively, pass in each path from the WinDbg GUI. For example:
windbg.exe -i "C:\mysql-5.7.32-winx64\bin\"^ -z "C:\mysql-5.7.32-winx64\data\mysqld.dmp"^ -srcpath "E:\ade\mysql_archives\5.7\5.7.32\mysql-5.7.32"^ -y "C:\mysql-5.7.32-winx64\bin;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols"^ -v -n -c "!analyze -vvvvv"Note
