cratedb_toolkit/docs/model.py (1)
1-22: 🛠️ Refactor suggestionGood addition of the DocsItem data class for documentation metadata management.
This new file and class bring better structure to documentation item handling by encapsulating metadata and source URL in a dedicated class. The
fetchmethod provides centralized HTTP request handling with proper timeout settings.Two suggestions for improvement:
- Consider adding explicit exception handling in the
fetchmethod to handle connection errors:def fetch(self) -> str: - response = requests.get(self.source_url, timeout=10) - if response.status_code != 200: - logger.error( - f"Failed to fetch documentation from {self.source_url}: HTTP {response.status_code}\n{response.text}" - ) - return response.text + try: + response = requests.get(self.source_url, timeout=10) + if response.status_code != 200: + logger.error( + f"Failed to fetch documentation from {self.source_url}: HTTP {response.status_code}\n{response.text}" + ) + return response.text + except requests.RequestException as e: + logger.error(f"Failed to fetch documentation from {self.source_url}: {e}") + return ""
- Consider returning None or raising an exception when the request fails, rather than returning potentially invalid content:
def fetch(self) -> str: response = requests.get(self.source_url, timeout=10) if response.status_code != 200: logger.error( f"Failed to fetch documentation from {self.source_url}: HTTP {response.status_code}\n{response.text}" ) - return response.text + return "" # or raise an exception + return response.text
🧹 Nitpick comments (5)
cratedb_toolkit/docs/settings.py (5)
35-39: GlobalDOCS_ITEMcreation is fine, but consider clarifying the ephemeral timestamp.
Usingdt.datetime.now().isoformat()ensures consistent logging. However, if the module is reloaded repeatedly, the creation time can differ across runs. A brief comment clarifying this behavior might help maintainers.
59-59: Consider handling non-200 responses more robustly.
AlthoughDocsItem.fetch()logs an error upon a non-200 response, the code continues with whatever content is returned. As an optional improvement, raise an exception to catch failed fetches early.For example, in
cratedb_toolkit/docs/model.py(unmodified in this PR), you could do:def fetch(self) -> str: response = requests.get(self.source_url, timeout=10) if response.status_code != 200: + logger.error( + f"Failed to fetch documentation from {self.source_url}: " + f"HTTP {response.status_code}\n{response.text}" + ) + response.raise_for_status() # Raise an exception instead of returning partial data return response.text
641-641: Guard against missing"settings"key into_markdown.
Ifself.thingis empty, referencingself.thing["settings"]may cause aKeyError. You could do the following to avoid potential runtime errors:-def to_markdown(self): - return write_markdown_table(self.thing["settings"]) +def to_markdown(self): + settings_data = self.thing.get("settings", {}) + return write_markdown_table(settings_data)
650-650: Likewise, avoidKeyErrorinto_sql.
Encapsulate the same guard to safely handle absent'settings'entries:-def to_sql(self): - return write_sql_statements(self.thing["settings"]) +def to_sql(self): + settings_data = self.thing.get("settings", {}) + return write_sql_statements(settings_data)
698-699: Generating SQL statements then synchronizingself.thingwithself.responseis logical.
You might consider exclusively relying onself.responseto reduce duplication, but the current approach is valid and preserves backward compatibility.

cratedb_toolkit/docs/cli.py (2)
84-84: Great improvement to error logging.Changing
logger.errortologger.exceptionwill capture the full exception traceback, which is extremely helpful for debugging. This change enhances error observability while maintaining the same behavior for end users.
111-111: Great improvement to error logging.Similar to the previous change, using
logger.exceptionhere ensures the full exception details are logged for the settings extraction process.tests/docs/test_cli.py (2)
28-28: Test updated to match new nested response structure.The test has been correctly updated to verify the new response structure, where settings data is now nested under a dedicated "settings" key. This aligns with the PR objective of giving metadata a dedicated slot.
93-93: Test updated to match new nested response structure.The YAML format test has been correctly updated to match the same nested structure pattern as the JSON test, maintaining consistency across output formats.
cratedb_toolkit/docs/functions.py (4)
13-13: Good addition of the new model import.Importing the newly created
DocsItemclass is necessary for the refactoring approach.
19-23: Good replacement of string constant with DocsItem instance.Replacing the simple string URL with a structured
DocsIteminstance improves code organization and allows for additional metadata to be associated with the documentation source.
48-48: Good update to the type of the meta field.Updating the
metafield type from a dictionary to theDocsItemclass aligns with the new approach for handling documentation metadata.
110-110: Good use of the DocsItem fetch method.Using
DOCS_ITEM.fetch()centralizes the HTTP request logic in theDocsItemclass, which is a good practice for code maintainability.cratedb_toolkit/docs/settings.py (11)
16-16: Import usage is appropriate.
The import fromdatetimeappears correctly used below for constructing thecreatedtimestamp.
26-26: ImportingDocsItemis correct.
This import aligns with the new approach to fetch documentation metadata viaDocsItem.
53-53: Logging the source URL is helpful.
Good to see the log referencingDOCS_ITEM.source_url, making troubleshooting easier.
63-63: Parsing payload with BeautifulSoup is straightforward.
Ifpayloadis empty, you'll simply parse an empty document, which is safe in this context.
653-653: Using@dataclasses.dataclassis a good move.
This aligns with Pythonic best practices for structured data handling.
654-658:SettingsResponsefields are well-defined.
Encapsulating the doc metadata (meta) and extracted settings in a single response object clarifies responsibility.
660-668: Returningdataclasses.asdict(self)is straightforward and reliable.
This approach simplifies conversions without manual dictionary assembly.
682-682: AttachingSettingsResponsetoSettingsExtractoris seamless.
This ensures all relevant data (including metadata) is readily available for rendering.
693-694: Storing extracted settings inresponseis consistent.
Replacing direct local usage ofextract_cratedb_settings()withself.response.settingscentralizes data handling in the dataclass.
696-696: Conditional check ofself.response.settingsis prudent.
Graceful handling of an empty result is important for debugging.
721-725: Runtime configurability log message is clear and informative.
Good to see the final count, helping users quickly confirm coverage.

cratedb_toolkit/docs/model.py (1)
19-26: Consider adding error retry logic to the fetch method.The fetch method correctly handles HTTP errors, but network requests can fail due to transient issues.
def fetch(self) -> str: - response = requests.get(self.source_url, timeout=10) - if response.status_code != 200: - logger.error( - f"Failed to fetch documentation from {self.source_url}: HTTP {response.status_code}\n{response.text}" - ) - response.raise_for_status() - return response.text + max_retries = 3 + retry_delay = 1 + + for attempt in range(max_retries): + try: + response = requests.get(self.source_url, timeout=10) + if response.status_code != 200: + logger.error( + f"Failed to fetch documentation from {self.source_url}: HTTP {response.status_code}\n{response.text}" + ) + response.raise_for_status() + return response.text + except (requests.RequestException) as e: + if attempt < max_retries - 1: + logger.warning(f"Fetch attempt {attempt + 1} failed, retrying in {retry_delay}s: {str(e)}") + time.sleep(retry_delay) + retry_delay *= 2 # Exponential backoff + else: + logger.error(f"Failed to fetch after {max_retries} attempts: {str(e)}") + raiseDon't forget to add
import timeat the top of the file if you implement this change.The static analysis hints indicate a lack of test coverage for this new class. Consider adding unit tests to verify both the success and error paths of the
fetchmethod.🧰 Tools

79-89: Assess metadata consistency forstats.enabled.
The metadata forstats.enabledis comprehensive; however, there is noticeable overlap between the"raw_description"and"purpose"fields. Consider consolidating the shared details to avoid redundancy, or ensure that each field serves a distinct purpose in downstream processing.
90-102: Verify consistency instats.jobs_log_sizemetadata.
Similar tostats.enabled, the metadata forstats.jobs_log_sizecontains overlapping content in the"raw_description"and"purpose"fields. It may be beneficial to review whether this duplication is intentional or if a streamlined approach could improve clarity.

56-57: Refined settings extraction description.
The change to specify [settings] in the description clarifies that the tool extracts settings-specific documentation. This clearer delineation should help users better understand the output structure.
73-77: Updated settings metadata.
The settings meta block now introduces a"source_url"that points to the CrateDB cluster configuration documentation. Confirm that the URL (line 76) accurately targets the intended resource and that the timestamp format matches the one used in the functions metadata.
108-109: New reference links added.
The document now includes explicit reference definitions for [scalar functions] and [settings], which will help users quickly navigate to the relevant CrateDB documentation. Ensure these links remain accurate as the documentation evolves.
