2023-05-01debug/pe: return error on reading from section with uninitialized dataIan Lance Taylor
A section with uninitialized data contains no bytes and occupies no space in the file. This change makes it return an error on reading from this section so that it will force the caller to check for a section with uninitialized data. This is the debug/pe version of CL 429601. This will break programs that expect a byte slice with the length described by the SizeOfRawData field. There are two reasons to introduce this breaking change: 1) uninitialized data is uninitialized and there is no reason to allocate memory for it; 2) it could result in an OOM if the file is corrupted and has a large invalid SizeOfRawData. No test case because the problem can only happen for invalid data. Let the fuzzer find cases like this.

2022-03-31debug/pe: add APIs for reading section def aux infoThan McIntosh
Add hooks to support reading of section definition symbol aux data (including COMDAT information) from the aux symbols associated with section definition symbols. The COFF symbol array made available by "pe.File" includes entries for aux symbols, but doesn't expose their structure (since it varies depending on the type of aux symbol). This patch adds a function for returning a specific class of aux symbol ("type 5") that immediately follows a COFF symbol corresponding to a section definition. Updates #35006. Updates #51868.

CLs 22181, 22332 and 22336 intorduced new functionality to be used in cmd/link (see issue #15345 for details). But we didn't have chance to use new functionality yet. Unexport newly introduced identifiers, so we don't have to commit to the API until we actually tried it. Rename File.COFFSymbols into File._COFFSymbols, COFFSymbol.FullName into COFFSymbol._FullName, Section.Relocs into Section._Relocs, Reloc into _Relocs, File.StringTable into File._StringTable and StringTable into _StringTable.

2016-04-24debug/pe: introduce File.COFFSymbols and (*COFFSymbol).FullNameAlex Brainman
Reloc.SymbolTableIndex is an index into symbol table. But Reloc.SymbolTableIndex cannot be used as index into File.Symbols, because File.Symbols slice has Aux lines removed as it is built. We cannot change the way File.Symbols works, so I propose we introduce new File.COFFSymbols that does not have that limitation. Also unlike File.Symbols, File.COFFSymbols will consist of COFFSymbol. COFFSymbol matches PE COFF specification exactly, and it is simpler to use.
