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.
For more information on PDB files and the debugging options available, see Debugging Tools for Windows.
To use WinDbg, either install the full Windows Driver Kit (WDK) or install the standalone version.
The .exe
and .pdb
files must be an exact match (both version number and MySQL
server edition); otherwise, or WinDBG complains while
attempting to load the symbols.
To generate a minidump
mysqld.dmp
, enable thecore-file
option under the [mysqld] section inmy.ini
. Restart the MySQL server after making these changes.Create a directory to store the generated files, such as
c:\symbols
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.exeLaunch
windbg.exe
giving it the paths tomysqld.exe
,mysqld.pdb
,mysqld.dmp
, and the source code. Alternatively, pass in each path from the WinDbg GUI. For example:windbg.exe -i "C:\mysql-8.0.40-winx64\bin\"^ -z "C:\mysql-8.0.40-winx64\data\mysqld.dmp"^ -srcpath "E:\ade\mysql_archives\8.0\8.0.40\mysql-8.0.40"^ -y "C:\mysql-8.0.40-winx64\bin;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols"^ -v -n -c "!analyze -vvvvv"
