After 1.21.3.01, Mojang removed debug information from BDS.
Mojang no longer provides any debugging information (both server and client) to the community.
Mojang has an agreement with LiteLDev to provide them with debug data.
LiteLDev generates header files and obfuscated symbol to RVA lookup tables from debug data and provides them to the community.

Problems caused by Mojang's collaboration with LiteLDev

Mojang's collaboration with LiteLDev is opaque and we have no idea what they do.
LiteLDev has completed its monopoly, and there will no longer be a second mod loader in the community.
Due to the obfuscated format, the community can no longer reverse engineer BDS.

Header files, obfuscation format and security

LeviLamina's design necessitates that they publish header files.
The header file contains all the declaration information so that symbols can be generated.
The RVA of the corresponding symbol can be extracted from the obfuscated format at runtime.
The obfuscated format is actually a carrier of the complete "symbol table", which used to be PDB/DWARF.

Tool for restoring original DebugInfo from obfuscated format

Note

LiteLDev has not yet released bedrock_runtime_data/magicblob for the Linux server.

They are dethunk, dumpsym, askrva and makepdb. Each tool is in a directory with the same name as it, and also has a README to help you use it.
In short, the PDB is generated by the following steps:

Preprocess the header files published by LiteLDev by dethunk.

python main.py {HEADER_PROJECT_DIR}/src

Compile the header file and load the dumpsym plugin in the compilation parameters.

xmake f -c -p windows -a x64 -m release --sdk=/opt/msvc --cxflags="-fplugin=/path/to/libdumpsym.so -fplugin-arg-dumpsym-record-decl-name" --toolchain=clang
xmake -v

Find the generated symbols file.

{HEADER_PROJECT_DIR}/build/.objs/bdsheader/windows/x64/release/test/__cpp_main.cpp.cpp.symbols

Generate symbol table using askrva.

./askrva __cpp_main.cpp.cpp.symbols --output succeed.json --output-failed failed.txt --output-format=makepdb

Generate PDB using makepdb.

./makepdb --program bedrock_server.exe --symbol-data succeed.json --output bedrock_server.pdb
