Try to find and install that specific version: + ```bash + pip install zuper-commons==X.Y.Z + ``` + +### Option 4: Maintain our Current Approach + +1. Keep `STRICT_DEPENDENCIES=False` +2.

Only use functionality that doesn't depend on the missing ZLogger + +## Recommended Approach + +For quick progress on the Python 3 migration, I recommend **Option 4** (maintain current approach) for now. + +If we need full quickapp functionality later, we should implement **Option 2** (patch quickapp) as it: +1. Is self-contained (doesn't require maintaining another fork) +2. Uses standard Python logging +3. Minimizes changes to the core codebase + +## Implementation Steps for Option 2 (if needed) + +1. Create a file `zlogger_patch.py` in the quickapp src directory +2. Implement the minimal ZLogger class +3. Update quickapp's `__init__.py` to use our patched version: + ```python + try: + from zuper_commons.logs import ZLogger + except ImportError: + from .zlogger_patch import ZLogger + ``` +4.

Dictionary keys in Python must be hashable (immutable) + - Classes like `RcompUnits` appear to be unhashable in the current implementation + +2. **Current Memoization Implementation**: + - Located in `src/mcdp_utils_misc/memoize_simple_imp.py` + - Uses a simple cache dictionary with tuples of arguments as keys + - Does not handle unhashable object types + +3. **Complex Object Types**: + - Many MCDP objects like `RcompUnits` are complex custom classes + - These classes don't implement `__hash__` or are mutable (thus unhashable) + - Such objects cannot be used as dictionary keys in their current form + +## Impact + +This issue prevents running tests that use these unhashable types as function arguments, which affects: + +1. The `syntax_anyof.py` tests, which use `RcompUnits` objects +2. Potentially many other tests throughout the codebase +3. Normal operation of functions that rely on memoization with these types + +## Potential Solutions + +### Approach 1: Make Objects Hashable + +1. **Implement `__hash__` and `__eq__` Methods**: + ```python + class RcompUnits: + def __hash__(self): + # Generate a hash based on immutable attributes + return hash(tuple(sorted(self.__dict__.items()))) + + def __eq__(self, other): + if not isinstance(other, RcompUnits): + return False + return self.__dict__ == other.__dict__ + ``` + +2. **Enforce Immutability**: + - Make relevant classes immutable by using read-only properties + - Prevent modification after initialization + - Use frozen dataclasses for new implementations + +**Pros**: +- Preserves existing memoization pattern +- More "Pythonic" approach for immutable objects + +**Cons**: +- Requires changes to multiple object classes +- Must ensure true immutability to avoid hard-to-debug issues +- May be difficult to determine which attributes should contribute to hash + +### Approach 2: Modify Memoization Strategy + +1. **Object ID Based Memoization**: + ```python + def memoize_simple(f): + cache = {} + def memoized(*args, **kwargs): + # Create a key based on object IDs instead of the objects themselves + key = tuple(id(arg) for arg in args) + if kwargs: + key += tuple((k, id(v)) for k, v in sorted(kwargs.items())) + + if key not in cache: + cache[key] = f(*args, **kwargs) + return cache[key] + return memoized + ``` + +2. **String Representation Memoization**: + ```python + def memoize_simple(f): + cache = {} + def memoized(*args, **kwargs): + # Create a key based on string representations + key = tuple(str(arg) for arg in args) + if kwargs: + key += tuple((k, str(v)) for k, v in sorted(kwargs.items())) + + if key not in cache: + cache[key] = f(*args, **kwargs) + return cache[key] + return memoized + ``` + +**Pros**: +- No need to modify the object classes +- Works with any object regardless of hashability + +**Cons**: +- Object ID memoization only works within a single execution (IDs can change between runs) +- String representation approach could be slower +- May lead to cache misses if string representation isn't unique + +### Approach 3: Custom Cache Keys + +1. **Custom Key Generation**: + ```python + def memoize_simple(f): + cache = {} + def memoized(*args, **kwargs): + # Try using the objects directly if hashable + try: + if kwargs: + kwargs_items = tuple(sorted(kwargs.items())) + key = (args, kwargs_items) + else: + key = args if args else () + + # Test if key is hashable + hash(key) + except TypeError: + # Fallback to string representation for unhashable objects + key = tuple(str(arg) for arg in args) + if kwargs: + key += tuple((k, str(v)) for k, v in sorted(kwargs.items())) + + if key not in cache: + cache[key] = f(*args, **kwargs) + return cache[key] + return memoized + ``` + +2. **Type-Specific Hash Functions**: + - Register custom hash functions for known unhashable types + - Use these functions to generate hashable keys + +**Pros**: +- More robust than the other approaches +- Graceful fallback for unhashable types +- Preserves efficient hashing when possible + +**Cons**: +- More complex implementation +- May still have edge cases with certain types + +### Approach 4: Alternative Caching Libraries + +1. **Use `functools.lru_cache` with Custom Keys**: + ```python + from functools import lru_cache + + def hashable_key(*args, **kwargs): + """Convert potentially unhashable arguments to a hashable key.""" + # Convert args to a hashable representation + hashable_args = tuple(str(arg) for arg in args) + # Convert kwargs to a hashable representation + hashable_kwargs = tuple(sorted((k, str(v)) for k, v in kwargs.items())) + return hashable_args + hashable_kwargs + + def memoize(func): + cached_func = lru_cache(maxsize=None)( + lambda key: func(*key[0], **dict(key[1])) + ) + def wrapper(*args, **kwargs): + args_key = tuple(args) + kwargs_key = tuple(sorted(kwargs.items())) + return cached_func((args_key, kwargs_key)) + return wrapper + ``` + +2. **Use External Caching Libraries**: + - `cachetools` library offers flexible caching decorators + - `joblib.Memory` for persistent caching + +**Pros**: +- Leverages battle-tested caching implementations +- May offer additional features (size limits, TTL, etc.) + +**Cons**: +- Adds external dependencies +- May require significant refactoring + +## Recommended Path Forward + +Given the analysis, here's the recommended approach: + +1. **Short Term (Minimal Change)**: + - Implement Approach 3 (Custom Cache Keys) to handle both hashable and unhashable types + - This minimizes changes to object classes while resolving the immediate issue + +2. **Medium Term**: + - Identify frequently memoized unhashable classes + - Implement `__hash__` and `__eq__` for these classes using immutable attributes + - Gradually convert key classes to be properly hashable + +3. **Long Term**: + - Consider moving to `functools.lru_cache` or another modern caching solution + - Make all relevant classes properly hashable following Python best practices + - Add proper cache size limits to prevent memory issues + +## Implementation Plan + +1. **Update Memoization Decorator**: + - Modify `memoize_simple_imp.py` to handle unhashable types using the hybrid approach + +2. **Test with Known Issue Cases**: + - Try running `syntax_anyof.py` tests with the new implementation + - Document any remaining issues + +3. **Document Design Decision**: + - Update code comments to explain the hybrid memoization approach + - Add notes to Python 3 migration documentation about this issue + +4. **Consider Class Refactoring**: + - Create a plan for gradually making key classes hashable + - Consider introducing a base class with consistent hash implementation + +This approach balances immediate fixes with long-term code health, allowing tests to pass while setting the stage for better practices in the future. \ No newline at end of file diff --git a/poset_commit_note.md b/poset_commit_note.md new file mode 100644 index 000000000..2a3faaae7 --- /dev/null +++ b/poset_commit_note.md @@ -0,0 +1,15 @@ +Update mcdp_posets module for Python 3 compatibility + +Migrated the complete mcdp_posets module to Python 3 with the following changes: +- Update metaclass syntax for Python 3 compatibility +- Convert string formatting to f-strings throughout +- Add __hash__ methods for classes with __eq__ methods +- Fix iterator handling (e.g., zip() returns iterator in Python 3) +- Replace deprecated time.clock() with time.process_time() +- Add explicit imports for functions no longer built-in (functools.reduce) +- Replace sys.maxint with sys.maxsize +- Fix invalid escape sequences in docstrings +- Update print statements in test files + +Testing is blocked by dependencies requiring migration (mcdp_library module). +Created posets_py3_progress.md to track and document all changes. \ No newline at end of file diff --git a/poset_migration_notes.md b/poset_migration_notes.md new file mode 100644 index 000000000..b4eebf037 --- /dev/null +++ b/poset_migration_notes.md @@ -0,0 +1,117 @@ + +Python 3 Migration Strategy for mcdp_posets + + Here's a structured migration strategy for the mcdp_posets module that can be resumed if we're interrupted: + + 1.

Several instances of mixed formatting styles (9 instances) + +## Key Patterns Identified and Fixed + +1. **Attribute access after object in f-string**: + ```python + # Before + s.info(f"Created from #{s}.creation_order") + + # After + s.info(f"Created from #{s.creation_order}") + ``` + +2. **Mixed f-string with %-style formatting**: + ```python + # Before + msg = f"Loop constraint not satisfied {F2.format(r} <= %s not satisfied.", F2.format(f2)) + + # After + msg = f"Loop constraint not satisfied {F2.format(r)} <= {F2.format(f2)} not satisfied." + ``` + +3. **Chained string formatting with .format()**: + ```python + # Before + t.log(f"R = {UR}".format(si_next)) + + # After + t.log(f"R = {UR.format(si_next)}") + ``` + +## Next Steps for Python 3 Migration + +1. **Address the remaining f-string issues systematically**: + - Apply the analysis and fixing scripts to the mcdp_lang directory + - Manual review of complex cases not handled by automatic fixing + - Focus on fixing mixed_format issues (highest complexity) + +2. **Continue pyparsing compatibility verification**: + - Ensure existing parsers work correctly with pyparsing 3.x + - Fix any specific issues in the compatibility layer + +3. **Resume migration of remaining mcdp_lang modules**: + - Apply f-string fixes + - Test parsing functionality after fixes + +4. **Expand to other modules**: + - Apply the same f-string fixing patterns to mcdp_dp, mcdp_opt, and other modules + - Document any module-specific issues encountered \ No newline at end of file diff --git a/src/mcdp_dp/dp_loop2.py b/src/mcdp_dp/dp_loop2.py index 33d493966..3ac12990a 100644 --- a/src/mcdp_dp/dp_loop2.py +++ b/src/mcdp_dp/dp_loop2.py @@ -148,9 +148,9 @@ def repr_hd_map(self): # try: # F2.check_leq(r, f2) # except NotLeq as e: -# msg = f"Loop constraint not satisfied {F2.format(r} <= %s not satisfied.", F2.format(f2)) -# msg += f"\n f1 = %10s -->| ->[ {F1.format(f1} ] --> %s ", self.dp1, F2.format(r)) -# msg += "\n f2 = %10s -->|" % F2.format(f2) +# msg = f"Loop constraint not satisfied {F2.format(r)} <= {F2.format(f2)} not satisfied." +# msg += f"\n f1 = {F1.format(f1):10s} -->| ->[ {self.dp1} ] --> {F2.format(r)}" +# msg += f"\n f2 = {F2.format(f2):10s} -->|" # raise_wrapped(NotFeasible, e, msg, compact=True) # # self.R.belongs(r) @@ -170,8 +170,7 @@ def check_unfeasible(self, f1, m, r1): if R0.leq(used, r): msg = f"loop: asking to show it is unfeasible ({f1}, {m}, {r})" msg += '\nBut inner is feasible and loop constraint *is* satisfied.' -
