Tess Strickland 0a4cb4d43e [pkg/native_stack_traces] Add support for MacOS universal binaries. 
In addition to adding a parser for the universal binary format, this
also requires major reworks to handle files that contain different
DWARF information for different architectures, and how to pass the
architecture down to where it's needed.

Also fix dSYM handling: instead of assuming the name of the MachO file
corresponds exactly to the basename of the dSYM with the extension
stripped, just look for the single file within the
Contents/Resources/DWARF directory.

Also add `unrecognized` enum entries for DW_TAG, DW_AT, and DW_FORM
values that aren't handled.

3.3 KiB
Raw Blame History

0.5.2

  • Adjusted logic for finding the DWARF MachO file in a dSYM.
  • Added support for retrieving DWARF information from universal macOS binaries using the new architecture information.
  • Added logic to handle unknown DW_AT, DW_FORM, and DW_TAG codes.

0.5.1

  • Parse new OS and architecture information from non-symbolic stack trace headers and store that information in PCOffsets when available.

0.5.0

  • Require Dart >= 2.17 (enhanced enum support)
  • Add support for parsing DWARF in Mach-O files and dSYM directories.
  • Add some support for DWARF5.
  • Add dump command to replace the old --dump_debug_file_contents flag to find and translate.

0.4.6

  • Upgrade to package:lints 2.0.
  • Populate the pubspec repository field.

0.4.5

  • Handle stack traces larger than 100 entries.

0.4.5-dev

  • Require Dart >= 2.14

0.4.4

  • Added handling of dynamic tables for testing.

0.4.3

  • Exported some more of the ELF utilities for use in Dart tests.

0.4.2

  • When decoding a stack trace, frames corresponding to the functions with DW_AT_artificial DWARF attribute are now omitted from the symbolized stack traces. This is needed because Dart VM no longer omits invisible functions from binary stack traces in certain cases.

0.4.1

  • Exported some ELF utilities in lib/elf.dart for use in Dart tests.

0.4.0

  • Stable null safe version of package.

0.4.0-nullsafety

  • Unstable null safe version of package.

0.3.8

  • Support columns when present in line number programs.

0.3.7

  • Added buildId accessor for retrieving GNU build IDs from DWARF files that include them.

0.3.6

  • Adjusts RegExp for stack trace header line to be more flexible in what it permits to allow additional information to be added in the Dart VM.

0.3.5

  • Use virtual addresses in non-symbolic stack frames as a fallback if we cannot retrieve an appropriate offset from the instructions section otherwise.

0.3.4

  • Decoded Dart calls are now never considered internal, only VM stub calls. This is due to a concurrent change in the Dart VM that no longer prints non-symbolic frames for functions considered invisible, which matches the symbolic frame printer and removes the need for the decoder to guess which frames should be hidden.

    This package still works on earlier versions of Dart, so the dependencies have not changed. However, it may print more frame information than expected when decoding stack frames from a Dart VM that does not include this change to non-symbolic stack printing.

0.3.3

  • No externally visible changes.

0.3.2

  • The find command can now look up addresses given as offsets from static symbols, not just hexadecimal virtual or absolute addresses.
  • Integer inputs (addresses or offsets) without an '0x' prefix or hexadecimal digits will now be parsed as decimal unless the -x/--force_hexadecimal flag is used.

0.3.1

  • Uses dynamic symbol information embedded in stack frame lines when available.

0.3.0

  • Adds handling of virtual addresses within stub code payloads.

0.2.2

  • Finds instruction sections by the dynamic symbols the Dart VM creates instead of assuming there are two text sections.

0.2.1

  • Added static method Dwarf.fromBuffer.

0.2.0

  • API and documentation cleanups

0.1.0

  • Initial release
