Dataclass __init__ is auto-generated at class creation time and not
present in the AST. The instrumentor was injecting a synthetic __init__
with super().__init__(*args, **kwargs) which calls object.__init__()
and fails because dataclass fields are passed as kwargs.
Now only skips when the class is a @dataclass AND has no explicit
__init__. Dataclasses with custom __init__ are still instrumented.
Replace substring assertions (e.g. `"// 2.89ms ->" in lines[7]`) with
exact full-output comparisons for better regression detection.

The base class had duplicate _get_java_sources_root and _fix_java_test_paths
methods that were overridden by JavaFunctionOptimizer. The base class also
had an is_java() block in generate_and_instrument_tests that used undefined
variables (used_behavior_paths, is_java). Removed all dead code since
JavaFunctionOptimizer.fixup_generated_tests handles this properly.
Also updated JavaFunctionOptimizer._fix_java_test_paths to accept
display_source parameter and use whole-word rename for collision handling.

Inner-class methods are intentionally skipped by Java discovery
(PR #1726) since instrumentation is name-only and not class-aware.
Update test to expect False from replacement.
Take omni-main-java's fix for E2E test runner path resolution —
uses os.path.relpath from __file__ instead of hardcoded relative path.
Also adds codeflash.toml detection for Java projects.
- Update test_inject_profiling_used_frameworks, test_async_run_and_parse,
test_pickle_patcher to use new inject_profiling_into_existing_test API
(test_string param removed)
- Add parse_line_profile_results function to parse_line_profile_test_output
module (imported by main's PythonFunctionOptimizer and test_instrument_tests)
Merges the omni-main-java branch which synced main into omni-java,
including JavaFunctionOptimizer, removal of is_java()/is_python() guards,
protocol dispatch for parse_test_xml, and deletion of concolic_testing.py.
Fix 10 failing tests: remove wrong assertions expecting import statements
inside extracted class code, use substring matching for UserDict class
signature, and rewrite click-dependent tests as project-local equivalents.
Add tests for resolve_instance_class_name, enhanced extract_init_stub_from_class,
and enrich_testgen_context instance resolution.
- Use instrumented class name in _cf_mod/_cf_cls markers to disambiguate
existing vs generated tests sharing the same original class name
- Encode line number in invocation IDs (L{line}_{counter}) for deterministic
call-site identification in inline runtime comments
- Rewrite add_runtime_comments() to annotate each call line with inline
performance data instead of a summary block at top
- Strip assertions before instrumenting so both modes share the same base source
- Update test expected strings for new marker format

Reverts ed2594bf which added --pool=forks to Vitest commands and
changed capture.js to use process.stdout.write and Vitest worker API.
These changes broke JS E2E tests (CJS, ESM, TS class) by altering
how all JS tests run, not just Vitest benchmarking.
The AI backend generates vitest/jest-style imports for Mocha projects.
Our sanitize_mocha_imports() stripped ESM `import { ... } from 'vitest'`,
but process_generated_test_strings() runs BEFORE postprocessing and calls
ensure_module_system_compatibility() which converts these to CJS requires.
Result: `const { ... } = require('vitest')` survived sanitization.
Added regexes for the CJS variants of vitest and @jest/globals requires.

Root cause: Vitest performance tests reported "20.0 seconds over 1 loop"
(JUnit XML wall-clock fallback) instead of actual per-function nanosecond
timing. This was a chain of two issues:
1. **stdout interception**: Vitest's default `threads` pool intercepts
process.stdout.write() and console.log(), preventing timing markers
from flowing to the parent process. Fixed by adding `--pool=forks`
to all Vitest commands and config files. The `forks` pool uses child
processes where stdout flows directly to the parent.
2. **test name detection**: Even after markers flowed through (43,000+
found in stdout), the parser couldn't match them to JUnit XML
testcases because all markers had "unknown" as the test name. This
happened because Vitest doesn't inject `beforeEach` as a global
(unlike Jest), so capture.js's Jest-style hook to set
`currentTestName` never fired.
Fixed by adding Vitest-specific test name detection in capture.js:
- Primary: `expect.getState().currentTestName` (full describe path)
- Fallback: `__vitest_worker__.current.fullTestName`
- Defense-in-depth: parser fallback matches "unknown" markers to
the first testcase when no name match is found
Result: cheerio's `isHtml` went from "20.0s / 1 loop" to
"902μs / 20,853 loops" with proper speedup analysis.

Three related fixes for Mocha test generation in CommonJS projects:

`require('node:assert/strict')` for CJS instead of ESM import syntax
2. ensure_module_system_compatibility() now converts ESM→CJS even when

Nested functions are now skipped by FunctionVisitor, and
discover_functions no longer swallows parse/IO errors — callers
handle them. Update test expectations accordingly.
When testsRoot overlaps moduleRoot (common in JS/TS monorepos like Ghost

(*.test.*, *.spec.*, __tests__/) when roots overlap, preserving the
existing directory-based filter for standard layouts.

parse_code_and_prune_cst now returns cst.Module instead of str.
add_needed_imports_from_module accepts cst.Module | str, skipping re-parse
when a Module is passed. This eliminates the string round-trip that caused
comments to migrate from statement leading_lines to Module.header,
resulting in comments appearing above imports instead of at their
original position.
Cache inspect.getmembers() results per module so repeated loop
iterations skip the expensive rescan. Add tests for get_runtime_from_stdout,
should_stop, _set_nodeid, _get_total_time, _timed_out, logreport, and
setup/teardown hooks.
Objects with __slots__ but no __dict__ (e.g. textual.cache.LRUCache)
fell through all comparator branches, logging "Unknown comparator input
type" and returning False — causing spurious test mismatches.
The comparator did not recognize `types.UnionType` (Python 3.10+ `X | Y`
syntax), causing it to fall through to "Unknown comparator input type".
Conditionally include it in the equality-checked types tuple.

Handle itertools.cycle on Python 3.14 where __reduce__ was removed by
falling back to element-by-element sampling. Add version guards for
pairwise (3.10+) and batched (3.12+) tests.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add a catch-all handler for itertools iterators (chain, islice, product,
permutations, combinations, starmap, accumulate, compress, dropwhile,
takewhile, filterfalse, zip_longest, groupby, pairwise, batched, tee).
Uses module check (type.__module__ == "itertools") so it automatically
covers any itertools type without version-specific enumeration. groupby
gets special handling to also materialize its group iterators.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
itertools.repeat uses repr() comparison (same approach as count).
itertools.cycle uses __reduce__() to extract internal state (saved items,
remaining items, and first-pass flag) since repr() only shows a memory
address. The __reduce__ approach is deprecated in 3.14 but is the only
way to access cycle state without consuming elements.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The comparator had no handler for itertools.count (an infinite iterator),
causing it to fall through all type checks and return False even for
equal objects. Use repr() comparison which reliably reflects internal
state and avoids the __reduce__ deprecation coming in Python 3.14.

The type inference for assertEquals always used the first argument, but
JUnit 4's 3-arg overload is assertEquals(message, expected, actual).

When running with --all on a Java project, codeflash was discovering .js
files inside apidocs/ and javadoc/ directories (generated Javadoc HTML)
and attempting to optimize them as JavaScript. This caused:
- "Invalid test framework for JavaScript/TypeScript" errors
- Wasted API calls for ~30+ functions from jquery-3.7.1.min.js
- Spurious "NO TESTS GENERATED" warnings for minified jQuery functions
Fix: add "apidocs" and "javadoc" to Java's dir_excludes. Because the
--all mode unions dir_excludes from all languages, these directories are
now skipped in both Java-specific and --all discovery modes.
Adds 5 tests verifying the exclusion works for Java mode and --all mode.

The root cause of 'database is locked' is orphaned Surefire JVM processes
after Maven timeout. The actual fix is killing the entire process group
(_run_cmd_kill_pg_on_timeout in test_runner.py).
The WAL mode / busy_timeout / sqlite3.connect(timeout=30) changes were
treating the symptom rather than the root cause. Revert them:
- codeflash/languages/java/instrumentation.py: remove PRAGMA journal_mode=WAL
and PRAGMA busy_timeout=30000 from inline SQLite write code
- codeflash/verification/parse_test_output.py: revert timeout=30 to default

- codeflash-java-runtime/src/main/java/com/codeflash/Comparator.java: revert busy_timeout PRAGMA

- codeflash/languages/java/resources/codeflash-runtime-1.0.0.jar: restored to pre-change JAR

class and revert snapshot strings
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Root cause of 'database is locked' errors:
- When Maven times out, subprocess.run() only kills the Maven parent process
- On Linux, Maven's forked Surefire JVM children become orphaned (not killed)
- Orphaned JVMs keep the SQLite result file open, causing SQLITE_BUSY when
Python reads the file immediately after Maven is killed
Fix: Replace subprocess.run() with _run_cmd_kill_pg_on_timeout() which uses
start_new_session=True + os.killpg() to kill the entire process group on
timeout, ensuring no orphaned JVMs are left behind.
Applied to: _compile_tests, _get_test_classpath, _run_tests_direct,
and _run_maven_tests (the main one).
Also adds 5 unit tests verifying:
- Successful commands return correct output
- Failing commands propagate returncode
- Child processes are killed (not orphaned) on timeout
- returncode is -2 on timeout
- Timeout is described in stderr
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Root cause: The instrumented test JVM holds a SQLite connection open while
writing results. The Python reader and the Java Comparator were trying to
read the same file without a busy_timeout, causing immediate SQLITE_BUSY
failures (~126 occurrences in codeflash_all_3.log).
Fixes applied:
1. instrumentation.py (_generate_sqlite_write_code):
Emit PRAGMA journal_mode=WAL and PRAGMA busy_timeout=30000 right after
each inline connection open. WAL mode lets readers see the last committed
state while a writer is active; busy_timeout makes lock collisions retry
instead of immediately failing.
2. parse_test_output.py (parse_sqlite_test_results):
Add timeout=30 to sqlite3.connect() so Python waits up to 30 s for a
transient lock to clear (default was 5 s, which was too short for a busy
Maven/JVM process).
3. Comparator.java (readTestResults):
Execute PRAGMA busy_timeout=30000 on the same connection before running
the SELECT, so the Java Comparator also retries instead of failing with
[SQLITE_BUSY].
4. CodeflashHelper.java (initializeDatabase) and ResultWriter.java (constructor):
Same WAL + busy_timeout PRAGMAs added after the initial getConnection() call
for the long-lived database connections used by these helper classes.
5. Updated codeflash-runtime-1.0.0.jar (rebuilt after Comparator/ResultWriter fix).
tests: add TestSQLiteLockedFix with two assertions —
• _generate_sqlite_write_code emits PRAGMA journal_mode=WAL and
PRAGMA busy_timeout=30000 before CREATE TABLE
• parse_sqlite_test_results uses timeout= in sqlite3.connect()

When the LLM optimises a method by introducing a new final field (e.g.
caching Arrays.hashCode in Expression.hashCode, or caching map.values() in
LuaMap.valuesIterator), it also modifies the class constructors to initialise
the field. Previously codeflash:
1. Added the new field to the class ✓
2. Replaced the target method ✓
3. Did NOT update the constructors ✗
This caused "variable X might not have been initialized" compilation errors.
Changes:
- `JavaAnalyzer.find_constructors` (+ `_walk_tree_for_constructors`,
`_extract_constructor_info`): new parser methods to locate
`constructor_declaration` nodes via tree-sitter.
- `JavaMethodNode.formal_parameters_text`: captures the raw parameter list
text so constructors can be matched by signature.
- `ParsedOptimization.modified_constructors`: new field to carry constructor
source texts that need to be replaced.
- `_parse_optimization_source`: extract constructors from the same class as
the target method and store in `modified_constructors`.
- `_replace_constructors`: new helper that replaces constructors in the
original source by matching on formal parameter signature.
- `replace_function`: call `_replace_constructors` after the main method
replacement when `modified_constructors` is non-empty.
Fixes regressions observed in codeflash_all_3.log:
LuaMap.valuesIterator, Expression.hashCode, Bin.hashCode,
NettyTlsContext.createHandler, Pool.capacity.

When the optimisation target lives in a static inner class (e.g.
ObjectUnpacker inside Unpacker<T>), the LLM-generated class often wraps the
inner class inside the full outer class. Previously, methods belonging to the
outer class were extracted as "helpers" and injected into the inner class,
causing compilation errors:
- "non-static type variable T cannot be referenced from a static context"
- "non-static variable offset cannot be referenced from a static context"
Two related fixes:
1. When _parse_optimization_source extracts helpers, it now skips any method
whose class_name differs from the target method's class_name.
2. The function now accepts an optional target_class_name parameter. When
there are multiple methods with the same name in the generated code (e.g.
an abstract outer-class method and the concrete inner-class override), the
method in the target class is preferred over outer-class methods.
Fixes the Unpacker.ObjectUnpacker.getString regression from codeflash_all_3.log.

Resolve `module.exports = varName` where varName is an object literal
containing methods. For patterns like `const utils = { match() {} };
module.exports = utils;`, the individual methods are now recognized as
exported. This fixes function discovery for CJS libraries like Moleculer.

Post-process find_functions() to mark functions as exported when they appear
in named export clauses like `export { joinBy }`. This fixes discovery for
TypeScript codebases (e.g., Strapi) that define const arrow functions and
export them via a separate export statement.

Ship a zero-dependency jest-reporter.js inside the codeflash runtime package
instead of requiring the external jest-junit npm package. This ensures the
reporter is always available when codeflash is installed, fixing Jest-based
projects (Strapi, Moleculer) that failed because jest-junit wasn't installed.

Two bugs in _parse_optimization_source (replacement.py) caused Maven compilation
failures when codeflash optimised aerospike-client-java:
Bug 1 – standalone method with wrong name replaces target
When the LLM generated a standalone method whose name did not match the
optimisation target (e.g. generated `unpackMap` for target `unpackObjectMap`,
or generated `sizeTxn` for target `estimateKeySize`), the function fell back to
using the entire generated snippet as `target_method_source`. This silently
replaced the target with the wrong method, producing:
• a duplicate definition of the wrong method
• removal of the target method (breaking all callers)
Fix: after parsing standalone (class-free) code, verify that at least one
discovered method matches the target name. If no match is found, set
`target_method_source` to the empty string and log a warning. A corresponding
guard in `replace_function` returns the original source unchanged when
`target_method_source` is empty.
The same guard is applied to the full-class path: if the generated class does
not contain the target method, the candidate is also rejected.
Bug 2 – anonymous inner-class methods hoisted as top-level helpers
When an optimised method returned an anonymous class (e.g. `keySetIterator`
returning `new Iterator<LuaValue>() { … }`), tree-sitter's recursive walk
found the anonymous class's `hasNext`, `next`, and `remove` method_declaration
nodes and classified them as helpers to be inserted at the outer-class level.
The inserted methods carried `@Override` annotations that matched nothing in the
outer class and referenced local variables (`it`) that were only in scope inside
the optimised method body, producing compilation errors.
Fix: when extracting helpers from the optimised class, skip any method whose
line range is entirely contained within the target method's line range. Such
methods belong to anonymous/nested classes inside the method body and must not
be hoisted out as standalone class members.
Tests added for both bugs in TestWrongMethodNameGeneration and
TestAnonymousInnerClassMethods.

- Base class keeps the language-routing replacement logic (used by both
Python and JS); Python subclass adds unused-helper revert on top via super()

- Move `ast` to TYPE_CHECKING in optimizer.py (fixes prek)
Handle itertools.cycle on Python 3.14 where __reduce__ was removed by
falling back to element-by-element sampling. Add version guards for
pairwise (3.10+) and batched (3.12+) tests.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add a catch-all handler for itertools iterators (chain, islice, product,
permutations, combinations, starmap, accumulate, compress, dropwhile,
takewhile, filterfalse, zip_longest, groupby, pairwise, batched, tee).
Uses module check (type.__module__ == "itertools") so it automatically
covers any itertools type without version-specific enumeration. groupby
gets special handling to also materialize its group iterators.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
itertools.repeat uses repr() comparison (same approach as count).
itertools.cycle uses __reduce__() to extract internal state (saved items,
remaining items, and first-pass flag) since repr() only shows a memory
address. The __reduce__ approach is deprecated in 3.14 but is the only
way to access cycle state without consuming elements.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The comparator had no handler for itertools.count (an infinite iterator),
causing it to fall through all type checks and return False even for
equal objects. Use repr() comparison which reliably reflects internal
state and avoids the __reduce__ deprecation coming in Python 3.14.

Nested functions are now skipped by FunctionVisitor, and
discover_functions no longer swallows parse/IO errors — callers
handle them. Update test expectations accordingly.
Extend extract_parameter_type_constructors to scan function bodies for
isinstance/type() patterns and collect base class names from enclosing
classes. Add one-level transitive stub extraction so the LLM also sees
constructor signatures for types referenced in __init__ parameters.
In enrich_testgen_context, branch on source: project classes get full
definitions, third-party (site-packages) classes get compact __init__
stubs to avoid blowing token limits.
Replace substring assertions with exact equality check against the full
expected output (EXPECTED_OUTPUT constant). Extract shared setup into a
run_replacement helper.

detect_unused_helper_functions only walked ast.Call nodes, missing methods
referenced via attribute assignment (e.g., self._parse1 = self._parse_literal).
This caused optimized helper methods used as callbacks to be incorrectly
reverted to their original code.

Objects with __slots__ but no __dict__ (e.g. textual.cache.LRUCache)
fell through all comparator branches, logging "Unknown comparator input
type" and returning False — causing spurious test mismatches.
Changed iteration_id in performance mode markers to properly encode
inner loop iterations for test case grouping:
- Single call: iteration_id = innerIteration (0, 1, 2...)
- Multiple calls: iteration_id = callId_innerIteration (1_0, 1_1, 2_0, 2_1...)
This allows test results to be properly grouped by InvocationId, where
each unique (call, inner_iteration) pair gets its own group for
calculating minimum runtimes across outer loops.
Fixed test expectations to match the new format.
All 43 Java performance tests passing.

parse_code_and_prune_cst now returns cst.Module instead of str.
add_needed_imports_from_module accepts cst.Module | str, skipping re-parse
when a Module is passed. This eliminates the string round-trip that caused
comments to migrate from statement leading_lines to Module.header,
resulting in comments appearing above imports instead of at their
original position.
Implemented CUDA-style loop ID calculation for performance mode:
- loopId = outerLoop * maxInnerIterations + innerIteration
- Behavior mode uses simple loop index (no inner iterations)
- Invocation ID simplified to call counter only
- Default CODEFLASH_INNER_ITERATIONS set to 10
Fixed critical bug in JavaAssertTransformer:
- Removed duplicate _special_re assignment that was missing parentheses
- Combined patterns into single regex: [\"'{}()]
- This fixes _find_balanced_parens and enables assertion transformation
Updated test expectations to match new marker format and loop ID calculation.
All 41 Java instrumentation tests passing.

Cache inspect.getmembers() results per module so repeated loop
iterations skip the expensive rescan. Add tests for get_runtime_from_stdout,
should_stop, _set_nodeid, _get_total_time, _timed_out, logreport, and
setup/teardown hooks.
feat: extend testgen type context to include function body references
Extract types referenced in the function body (constructor calls, attribute
access, isinstance/issubclass args) in addition to parameter annotations.
Use full class extraction instead of init-stub-only, with instance resolution
fallback and project/site-packages filtering.
Java stdout markers now include the test method name in the class field
(e.g., "TestClass.testMethod") matching the Python marker format. The
parser extracts the test method name from this combined field.

The instrumented Java test code was storing "{class_name}Test" as the
test_function_name in SQLite instead of the actual test method name
(e.g., "testAdd"). This fixes parity with Python instrumentation.
- Add _extract_test_method_name() with compiled regex patterns
- Inject _cf_test variable with actual method name in behavior code
- Fix setString(3, ...) to use _cf_test instead of hardcoded class name
- Optimize _byte_to_line_index() with bisect.bisect_right()
- Update all behavior mode test expectations

Increase tolerance for individual timing measurements from ±2% to ±5%
to accommodate JIT warmup effects where first iterations run slower

Four bugs in _insert_class_members / replace_function:
1. Extra indentation on injected methods (textwrap.dedent now normalises source before re-indenting)
2. New fields were prepended before existing ones (now inserted after the last existing field)
3. Helper methods were always appended at end of class (now placed before/after target based on their position in the optimised code)
4. No blank lines between consecutively injected helpers (each helper is now followed by a blank line)

Replace lazy `.*?` quantifiers in matches_re_start/matches_re_end with
negated character classes (`[^:]`, `[^#]`, `[^.:]`) to eliminate
quadratic backtracking. Replace per-line regex search for the pytest
FAILURES header with a simple `"= FAILURES =" in line` string check.

- Increase imported type skeleton token budget from 2000 to 4000
- Add constructor signature summary headers to skeleton output
- Expand wildcard imports (e.g., import com.foo.*) into individual types
instead of silently skipping them
- Prioritize skeleton processing for types referenced in the target method
so parameter types are guaranteed context before less-critical types
- Fix invalid [no-arg] annotation in constructor summaries

Fix 10 failing tests: remove wrong assertions expecting import statements
inside extracted class code, use substring matching for UserDict class
signature, and rewrite click-dependent tests as project-local equivalents.
Add tests for resolve_instance_class_name, enhanced extract_init_stub_from_class,
and enrich_testgen_context instance resolution.
Add enrichment step that parses FTO parameter type annotations, resolves
types via jedi (following re-exports), and extracts full __init__ source
to give the LLM constructor context for typed parameters.
Bug 4 (candidate_early_exit.py - 6 tests):
- All tests failed → 0 total passed (guard triggers)
- Some tests passed → nonzero (guard does not trigger)
- Empty results → 0 passed (guard triggers)
- Only non-loop1 results → ignored by report (guard triggers)
- Mixed test types all failing → 0 across all types
- Single passing among many failures → prevents early exit
Bug 3 edge cases (context.py - 8 tests):
- Wildcard imports are skipped (class_name=None)
- Import to nonexistent class returns None skeleton
- Skeleton output is well-formed Java (has braces)
- Protected and package-private methods excluded
- Overloaded public methods all extracted
- Generic method signatures extracted correctly
- Round-trip: _extract_type_skeleton → _format_skeleton_for_context
- Round-trip with real MathHelper fixture file

Replace inline code injection with a helper file approach that writes
decorator implementations to a separate codeflash_async_wrapper.py file.

Instead of injecting `from codeflash.code_utils.codeflash_wrap_decorator import ...`
into instrumented source files, inject the decorator function definitions directly.
This removes the hard dependency on the codeflash package being importable at runtime
in the target environment, matching the pattern already used for sync instrumentation.
In --all mode, stale line numbers in FunctionToOptimize caused
InvalidJavaSyntaxError when a prior optimization modified the same file.
Now extract_function_source re-parses with tree-sitter to find methods

Move code_context_extractor.py and unused_definition_remover.py from
codeflash/context/ to codeflash/languages/python/context/ and update
all import sites.
Consolidate three enricher functions (get_imported_class_definitions,
get_external_base_class_inits, get_external_class_inits) into a single
enrich_testgen_context that parses code context once. Extract shared
helpers, unify prune_cst variants, deduplicate loop bodies, and remove
dead UsedNameCollector class.
The formatter correctly removed the unused re-exports from
parse_test_output.py. Update the test to import directly from
codeflash.languages.javascript.parse.
Add BFS-based transitive resolution so that classes referenced in __init__
type annotations of imported external classes are also extracted. This gives
the LLM the constructor signatures it needs to instantiate parameter types.
When tests_root overlaps with module_root (e.g., both set to "."),
the pattern matching in is_test_file() missed Python's standard
test_*.py naming convention and conftest.py files. Also adds pytest
fixture filtering in the libcst FunctionVisitor to prevent fixtures
from being discovered as optimizable functions.
The coverage system was using bare function_name (e.g., "__init__")
instead of qualified_name (e.g., "HttpInterface.__init__"), causing
it to match the wrong class's method when multiple classes define
the same method name (like __init__).
Changes:
- function_optimizer.py: pass qualified_name to parse_test_results
- build_fully_qualified_name: skip re-qualifying already-qualified names
- extract_dependent_function: compare using bare name from qualified input
- grab_dependent_function_from_coverage_data: replace substring match with
exact or dot-bounded suffix match
Add DependencyResolver protocol and IndexResult to base.py, move
call_graph.py to languages/python/, and use factory method in optimizer
instead of is_python() gating.

Fixed two test failures in omni-java:
1. test_formatter_cmds_non_existent:
- Default formatter-cmds changed from ["black $file"] to [] (commit c587c475)
- Updated test expectation to match new default
- Formatter detection now handled by project detector
- Empty list prevents "Could not find formatter: black" errors for Java projects
2. test_float_values_slightly_different:
- Python comparator now uses math.isclose(rel_tol=1e-9) for numeric comparison (commit 98a5a438)
- Updated test to expect equivalent=True for values within epsilon tolerance
- Added test_float_values_significantly_different to verify detection of actual differences
- Test added before epsilon-based comparison was implemented, causing mismatch
Both tests now pass and accurately reflect current codebase behavior.

Resolved conflicts by merging the best of both branches:
- Kept exception_class field from PR for better exception type detection
- Adopted more general variable assignment detection from omni-java
- Combined exception replacement logic to use exception_class with fallback
- Added double catch (specific exception + generic Exception) for robustness
- Merged test cases from both branches with updated expectations
Changes:
- Updated AssertionMatch to include all fields: assigned_var_type, assigned_var_name, exception_class
- Lambda extraction now works for all exception assertions
- Exception class extraction specifically for assertThrows
- Variable assignment detection handles final modifier and fully qualified types
- Exception replacement uses exception_class or falls back to assigned_var_type

When assertThrows was assigned to a variable to validate exception
properties, the transformation generated invalid Java syntax by
replacing the assertThrows call with try-catch while leaving the
variable assignment intact.
Example of invalid output:
IllegalArgumentException e = try { code(); } catch (Exception) {}
This fix detects variable assignments, extracts the exception type
from assertThrows arguments, and generates proper exception capture:
IllegalArgumentException e = null;
try { code(); } catch (IllegalArgumentException _cf_caught1) { e = _cf_caught1; } catch (Exception _cf_ignored1) {}

Merged omni-java base into PR #1279 to resolve conflicts.
Resolution approach:
1. test_discovery.py: Used refactored method call resolution from base
- New approach uses sophisticated type tracking (jedi-like "goto")
- Already includes duplicate checking (line 141)
- Removed old Strategy 3 (class-based fallback) as it's not needed
and caused single-function optimization issues
2. test_instrumentation.py: Combined both changes
- Added API key setup from PR #1279
- Kept FunctionToOptimize imports from base
The refactored code is more accurate and fixes the single-function
optimization issue that existed in the original PR.
