Release Notes

gimli-rs/object (object)

v0.40.0

Compare Source

Released 2026/08/01.

Breaking changes

• Changed many file format struct fields and constants to use newtypes.
  Newtypes for bit flags have methods such as contains and intersects.
  Some constants are fields within another newtype and have methods for conversion.
  The raw values are always accessible by .0.

• Updated macho::DyldCacheHeader to dyld-1340.
  #​885

• Deleted SectionKind::Elf and added sh_type field to SectionFlags::Elf.
  #​891

• Added feature gates to variants of FileFlags, SegmentFlags,
  SectionFlags, SymbolFlags, and RelocationFlags.
  #​891

• Added p_type field to SegmentFlags::Elf.
  Added n_type field to SymbolFlags::MachO.
  Added typ and storage_class fields to SymbolFlags::CoffSection.
  Added n_type field to SymbolFlags::Xcoff.
  Added reserved2 field to SectionFlags::MachO.
  #​891
  #​963

• Renamed build::elf::AttributeTag to AttributeScope.
  #​894

• Changed write::elf::Writer::reserve_strtab/reserve_shstrtab/reserve_dynstr
  and write::coff::Writer::reserve_symtab_strtab to return an Error for
  null bytes in strings, or table size overflow.
  #​905

• Changed many write::elf::Writer methods to return u64 instead of usize.
  #​909

• Replaced name fields in write::elf::SectionHeader, write::elf::Sym,
  write::elf::Verdef and write::elf::Vernaux with string table offsets.
  Added write::elf::Writer methods to obtain these offsets.
  #​910

• Added hash fields to write::elf::Verdef and write::elf::Vernaux.
  Use elf::hash to calculate the hash values.
  #​910

  and replaced build::elf::Builder::class with encoder.
  #​910

• Deleted write::elf::Writer::reserve_*_section_index_with_name
  and write::elf::Writer::reserve_dynamics. There is no replacement
  for these.
  #​912

• Changed offsets from usize to u64 in write::WritableBuffer
  and low level writing APIs.
  #​914

• Improved overflow handling when writing. Some overflow handling for
  write::elf::Writer has been shifted to the caller, as indicated by
  narrowed parameter types for reserve_program_headers,
  reserve_gnu_verdef and reserve_gnu_verneed.
  #​918

• Added tool version data to read::macho::LoadCommandVariant::BuildVersion
  and endian parameter to read::macho::LoadCommandData::build_version.

  write::WritableBuffer::len. Added write::CountingBuffer which can
  wrap WritableBuffer to provide resize and count methods.
  #​930
  #​931

• Moved write::WritableBuffer::write_pod and write_pod_slice to a
  new write::WritableBufferExt trait, and deleted the write and
  write_slice methods for dyn WritableBuffer.
  #​930

• Sealed low level parsing traits.
  #​934

• Renamed read::coff::ImageSymbol to read::coff::Symbol.
  #​936

• Added read::pe::ExportOrdinal and read::pe::ExportAddressIndex,
  and changed read::pe::ExportTable methods to use them.
  #​942

• Changed read::Object::imports and read::Object::exports to iterators,
  and expanded read::Import and read::Export to handle more types of
  imports and exports. Import::name and Export::name return NameOrOrdinal
  and Export::address is replaced by Export::target.
  #​941
  #​945
  #​946
  #​949
  #​955
  #​956

• Fixed handling of common symbols for Mach-O; it is now similar to other formats.
  Folded SectionKind::Common into SectionKind::UninitializedData and
  deleted write::StandardSection::Common, and write::Object::has_common.
  read::macho::Nlist::is_undefined now excludes common symbols.
  #​964

This is safe to merge - the benchmark failure cannot be related to these changes since object is only used on the solx stack-trace path. I'm investigating these types of benchmark failures.
