BlackHat Asia 2024 -- Ides of March

Lots of changes major changes. API has changed.

We now support many disassembly options:

• classic: disasm-like output
• bytes: disasm-like output with bytecode
• extended: simple interpretation of previous sequence of instructions
• extended-bytes: same as above, but with "bytes" bytecode ouptut
• header: show header/metadata information only

This is reflected in the --format (-F) options on pydisasm.
Option --show-source (-S) gives add the source text line (or part of it) before assembly instructions that implement the line.

Released Python magic numbers have been updated as of this release (up to Python 3.12.2, including PyPy magic numbers.

Some support for the GraalVM
implementation of Python started.

Many bugs fixed.

A lot of Linting and coding style modernization.

typing.NameTuple used for Python versions that support this.
Additional fields "start_offset" and "tos_str" added to instruction.

Elliot Tarbet (2elli) largely provided support for Python 3.11 and 3.12 bytecode

Season Update

• Detect versions pypy3.8.15, pypy-3.9.15
• Dectect Python 3.{7,8,9}.14 3.10.{5,6,7}
• correct 3.10+ pydisasm -F xasm label
• Revise marshal error handling (Issue #97)
• Improve PyPy 3.7 CALL_FUNCTION arg interpretation
• Fix 1.5-2.x bugs in line number encoding
• Fix showing MAKE_FUNCTION operand
• Miscellaneous lint, black, and isort changes

HF+LB-1

• Detect 3.7.[7-13], 3.9.[8-13], 3.10.[1-4], PyPy 2.7.12, 3.[8-9]pypy
• Correct line-number detection on Python 1.0-1.4
• Handle SET_LINENO in older pythons
• Warn about wrong names in after RESERVE_FAST in Python 1.x
• Some PyPy x-3.9.7 tolerance
• Add Pypy 3.8 support
• Better PyPy 3.6 formatting
• Correct relative jump target calculation in 3.10

6.0.3

• xasm format fixes
• more Python version tuple compare conversions
• add version_str_to_tuple() to convert the other way. This is useful in xasm, for example.

Jed + Rocky average

• Remove str2float(), sysinfo2float() and magic_int2float(). With Python 3.10, this is no longer tenable
• Reduce PYTHON_VERSION usage in xdis.
• Allow optional delimiter and start length in version_tuple_to_str()
• fix logic bug in setting MAGIC
• Add a little Python 3.8.5 Graal (Java VM) knowledge.

6.0.1

• Add PyPy 3.8 opcodes and disassembly
• Accept Python 3.8.12
• Fix some small lingering bugs introduced converting Python version number floats to tuples

6.0.0

Reworked for Python 3.10.

We had been internally using floating point numbers for version testing.
Clearl this doesn't work to distinguish 3.1 from 3.10.
(This was a flaw known about for a while and we'd been avoiding).

• Add 3.10 opcodes.
• Add 3.9 and 3.10 testing.
• Some tolerance for running from 3.11
• Update magic numbers
• Expanding testing to include pyston and PyPy 3.7
• Improve distribution packaging, e.g. Python 3 wheels should no longer be attmpted on Python 2.x

5.0.13

Added knowledge of Python versions 3.6.15 and 3.7.12.

However the main motivation was to impove packaging to handle administration
of the 3 different branches or dialects of Python 2.4-2.7, 3.1-3.2, 3.3-3.5, and 3.6+

Restrict wheel packaging for Python 3 only.

Use the wheel for only the 3.x and newer version of Python.
Use eggs for 2.x versions (and others as well).

5.0.12

• Add Python version 3.9.7
• Document unmarshal better
• Correct stack information for IMPORT_NAME
• Fix bug in code type handling where bytes were showing up as strings
• More type annotations in master branch. Create more older variations without annotations

Independence plus one

• Add Python versions 3.9.6, 3.7.11, 3.8.11, and 3.6.14
• Format Python various files using black. (Not completely done yet though)
