This is a Rust library that parses Microsoft PDB (Program Database) files. These files contain debugging information produced by most compilers that target Windows, including information about symbols, types, modules, and so on.
The PDB format is not documented per sé, but Microsoft has published
information in the form of C++
code relating to its use. The PDB format is full of... history, including
support for debugging 16-bit executables, COBOL user-defined types, and myriad
other features. pdb does not understand everything about the PDB format,
but it does cover enough to be useful for typical programs compiled today.
pdb's design objectives are similar to
gimli:
-
pdbworks with the original data as it's formatted on-disk as long as possible. -
pdbparses only what you ask. -
pdbcan read PDBs anywhere. There's no dependency on Windows, on the DIA SDK, or on the target's native byte ordering.
use pdb::FallibleIterator;
use std::fs::File;
fn main() -> pdb::Result<()> {
let file = File::open("fixtures/self/foo.pdb")?;
let mut pdb = pdb::PDB::open(file)?;
let symbol_table = pdb.global_symbols()?;
let address_map = pdb.address_map()?;
let mut symbols = symbol_table.iter();
while let Some(symbol) = symbols.next()? {
match symbol.parse() {
Ok(pdb::SymbolData::Public(data)) if data.function => {
// we found the location of a function!
let rva = data.offset.to_rva(&address_map).unwrap_or_default
println!("{} is {}", rva, data.name);
}
_ => {}
}
}
Ok(())
}Run with cargo run --release --example <name>:
-
pdb_symbolsis a toy program that prints the name and location of every function and data value defined in the symbol table. -
pdb2hppis a somewhat larger program that prints an approximation of a C++ header file for a requested type given only a PDB. -
pdb_linesoutputs line number information for every symbol in every module contained in a PDB.
Real-world examples:
-
mstange/pdb-addr2lineresolves addresses to function names, and to file name and line number information, with the help of a PDB file. Inline stacks are supported. -
getsentry/symbolicis a high-level symbolication library supporting most common debug file formats, demangling, and more.
