* Align CFG cleanup bytecode with CPython
* Bytecode parity: fblock unwind, fstring join, folding, scope
- compile.rs: unwind_fblock_stack returns whether a finally ran so
return-statement emission can adjust location handling; restructure
try/except/finally cleanup to preserve or drop boundary NOPs based on
whether the body falls through; rework f-string lowering with
count/join helpers; remove the per-collection-type heuristic for
AST-level folding and defer to flowgraph passes; add several folding
helpers and a ComprehensionLoopControl enum.
- ir.rs: re-run unary/binop folding around tuple folding, add
reorder_conditional_scope_exit_and_jump_back_blocks and several block
classification helpers, add MAX_STR_SIZE, change is_exit_without_lineno
to take the block list.
- symboltable.rs: in analyze_cells, remove names owned as cells in
function-like scopes from the parent's free set; mark lambda scope
type explicitly.
* Refine CFG scope-exit backedge ordering
This directory contains all of the Python files that make up the standard
library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7
branch), with slight modifications to allow them to work under RustPython. The
current goal is to complete the standard library with as few modifications as
possible. Current modifications are just temporary workarounds for bugs/missing
feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
