LCORE-1072: Better comments in models #877
Conversation
WalkthroughExpanded and clarified docstrings across configuration, request, and response models; added targeted runtime validations (CORS credential+wildcard, DB backend selection/default-to-SQLite, LlamaStack library-mode and path checks, JWT role/regex validation, user-data writability) and tightened FeedbackRequest normalization/validation.

135-143: Clarify the docstring summary to specify wildcard origins.The summary "credentials are not allowed" is ambiguous. Consider rewording to make it clear this constraint applies specifically when wildcard origins are configured.
Apply this diff:
- """ - Validate CORS settings and enforce that credentials are not allowed. + """ + Validate CORS settings and enforce that credentials are not allowed with wildcard origins.

936-983: Authentication validator docstring should mention API key module requirementsThe validator enforces module‑specific config for three cases: JWK, RH Identity, and API key. The docstring, however, only mentions JWK and RH Identity in both the high‑level description and the
Raisessection. To avoid confusion, consider updating it, e.g.:- Checks that the selected authentication module is supported and that any module-specific - configuration (JWK or RH Identity) is present when required. + Checks that the selected authentication module is supported and that any module-specific + configuration (JWK, RH Identity, or API key) is present when required. @@ - ValueError: If the module is unsupported, or if a required module-specific - configuration (jwk_config for JWK token or rh_identity_config for RH Identity) - is missing. + ValueError: If the module is unsupported, or if a required module-specific + configuration (jwk_config for JWK token, rh_identity_config for RH Identity, + or api_key_config/api_key for API key auth) is missing.This will better reflect the existing
AUTH_MOD_APIKEY_TOKENbranch and theapi_keypresence check.

src/models/config.py (3)
133-152: Clarify credentials restriction to wildcard origins onlyThe phrase “enforce that credentials are not allowed” reads as if credentials are never allowed, whereas the implementation only forbids
allow_credentials=Truewhen"*"is inallow_origins. Consider tightening the wording to avoid confusion, e.g.:- Validate CORS settings and enforce that credentials are not allowed. + Validate CORS settings and enforce that credentials are not allowed + when "*" is present in `allow_origins`.
499-518: Llama Stack validator docstring mostly matches logic; clarify URL semantics in library modeThe docstring accurately describes:
- Requiring explicit library‑client mode when
urlisNone.- Requiring
library_client_config_pathand checking it viafile_checkwhenuse_as_library_clientisTrue.- Normalizing
use_as_library_client is NonetoFalse.However, the inline comment later states that in library‑client mode “Llama Stack URL should not be set”, while the code does not enforce
url is Nonewhenuse_as_library_clientisTrue. Consider either:
- Adding a validation that raises if
use_as_library_clientisTrueandurlis notNone, or- Relaxing that comment/doc wording to say the URL is ignored in library mode instead of forbidden.
This will keep behavior and documentation aligned.
1171-1187: Conversation cache validation docstring matches main cases; consider documentingnoopsemanticsThe documented
ValueErrorconditions fortype is Nonewith a backend, and for mismatchedtypevsmemory/sqlite/postgresconfigs, match the implementation.One possible enhancement: when
type == "noop"(allowed by the field type), the current logic silently accepts any provided backend configs, which may surprise users. If the intended semantics are “no caching and no backend should be configured”, you might either:
- Extend validation to reject backends when
type == "noop", and/or- Mention in the docstring how
noopinteracts with backend configs.This would make the behavior around the
nooptype less ambiguous.

73-82: TLS post‑validation docstring matches current no‑op behaviorThe expanded docstring correctly states that this validator is currently a no‑op that returns
self, which matches the implementation.
177-188: PostgreSQL configuration overview is accurate and helpfulThe additional context on how PostgreSQL is used (conversation IDs, history, quota usage) is clear and aligns with the surrounding configuration.
245-257: PostgreSQL port validation docstring matches logicDocstring correctly documents that only ports
> 65535are rejected, with the lower bound already enforced byPositiveInt.
279-302: Database backend selection docstring matches defaulting behaviorThe description of defaulting to
/tmp/lightspeed-stack.dbwhen no backend is configured, and erroring when multiple backends are set, matches the implementation.
304-316:db_typeproperty docstring matches behaviorThe documented return values (
"sqlite"/"postgres") and theValueErrorcase when neither is set are consistent with the property logic.
323-336:configproperty docstring is precise and accurateThe Returns/Raises sections correctly describe the selection between SQLite and PostgreSQL configs and the error when neither is configured.
345-351: Service description is clearer and aligned with implementationThe expanded explanation of host/port, auth, and worker behavior matches how
ServiceConfigurationis used.
408-421: Service port validation docstring matches logicDocstring correctly notes that ports above 65535 raise
ValueError, which matches the validator body.
424-438: MCP server description is clear and consistentThe explanation of MCP servers and the note that only those defined in
lightspeed-stack.yamlare available is clear and consistent with the config shape.
582-595: User data storage validation docstring matches checksThe docstring correctly states that when feedback/transcripts are enabled, their respective storage paths must be provided and writable (exist or creatable), matching the
directory_checkusage.
667-679: JSONPath validation docstring matches error behaviorThe description of parsing
jsonpathand raisingValueErrorwith the offending expression and parser error is consistent with thetry/except JSONPathErrorblock.
690-700: Role list validation docstring matches implemented constraintsDocstring correctly documents the three checks (non‑empty, unique roles, no
"*"), all of which are present in the implementation.
715-726: Regex pattern validation docstring matches MATCH behaviorThe documented requirement for
valueto be a valid regex string whenoperator == MATCHaligns with theisinstance(self.value, str)andre.compilechecks.
740-749:compiled_regexdocstring is now clear and line‑length compliantThe Returns description precisely matches the logic (compile only for MATCH + string value, otherwise
None) and resolves the prior line‑length linter complaint.
985-996: JWK configuration accessor docstring matches behavior and lint fixThe Returns/Raises description matches the property logic and the reflowed
Raisesline resolves the earlier line‑length issue.
1005-1016: RH Identity accessor docstring matches error casesDocstring correctly documents that it raises if the module is not RH Identity or if the configuration is missing when it should be present, consistent with the implementation.
1065-1071: Custom profile prompts accessor docstring is accurateThe method simply returns
self.prompts, and the docstring clearly describes this mapping.
1084-1095: Customization loading docstring matches profile/system prompt behaviorThe explanation of preferring
profile_pathoversystem_prompt_path, validating files, and populatingcustom_profileorsystem_promptreflects the control flow in the validator, and the reflow fixes prior line‑length issues.
1122-1132: Default model/provider coupling docstring matches validationThe docstring correctly states that
default_modelanddefault_providermust be set together or both unset; the two conditional checks enforce exactly that.
1467-1477: Configuration dump docstring matches implementation and addresses line lengthThe description of JSON serialization (indent=4, UTF‑8, overwrite behavior) matches the
open(..., "w", encoding="utf-8")andmodel_dump_json(indent=4)call, and the wrapped lines fix the prior linter complaint.
