📝 Walkthrough

Walkthrough

Enhances webhook participant loading with per-participant timeouts to avoid hangs, adds connection-pool tuning to multiple Postgres DataSource configs, and refactors the subscriber afterUpdate flow to reload, enrich, and debounce post‑commit entity notifications.

Changes

Cohort / File(s)	Summary
Webhook participant loading platforms/cerberus/src/controllers/WebhookController.ts	Replaced prior per-participant async loading with a per-item async function that safely extracts userId, wraps each repository call in a 5s Promise.race timeout, and uses Promise.allSettled to collect valid participants; adds per-index error logging.
Subscriber reload-and-notify workflow platforms/cerberus/src/web3adapter/watchers/subscriber.ts	Reworked afterUpdate handling to derive entityId from multiple sources and schedule a debounced post‑commit reload. Added private handleChangeWithReload and executeReloadAndSend methods that reload/enrich the entity, convert to plain data, skip junctions/non-system messages, and call adapter.handleChange. Includes additional guards and logging.
Database connection pool configs platforms/cerberus/src/database/data-source.ts, infrastructure/evault-core/src/config/database.ts, platforms/dreamsync-api/src/database/data-source.ts, platforms/eCurrency-api/src/database/data-source.ts, platforms/eReputation-api/src/database/data-source.ts, platforms/emover-api/src/database/data-source.ts, platforms/esigner-api/src/database/data-source.ts, platforms/evoting-api/src/database/data-source.ts, platforms/file-manager-api/src/database/data-source.ts, platforms/group-charter-manager-api/src/database/data-source.ts, platforms/pictique-api/src/database/data-source.ts, platforms/registry/src/config/database.ts	Added an extra block to DataSource/DataSource options across multiple platforms with connection-pool and timeout settings (max: 10, min: 2, idleTimeoutMillis: 30000, connectionTimeoutMillis: 5000, statement_timeout: 10000). Review for consistent naming/typing and environment compatibility.

Poem

🐰
I hopped through logs and timeouts bright,
Per‑participant naps cut short at night,
I fetch, I reload, I debounce with care,
Group chats chirp now — no hangs in the air! ✨

🚥 Pre-merge checks | ✅ 3 | ❌ 2

❌ Failed checks (2 inconclusive)

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The PR addresses issue #638 (Cerberus group chat failures) through connection pool additions and webhook/subscriber improvements, but the connection between specific code changes and the expected behavior is not explicitly documented.	Clarify in the PR description how the connection pool and webhook timeout changes specifically address the notification and charter violation processing failures described in issue #638.
Out of Scope Changes check	❓ Inconclusive	The PR contains mostly in-scope changes (database pool configurations and webhook/subscriber enhancements) related to fixing database hangups, but includes additional changes to subscriber reload logic that may extend beyond the immediate scope of connection pooling.	Review whether the subscriber reload-and-notify workflow (155 lines added) is necessary for the core hangup fix or if it should be separated into a distinct PR for better clarity.

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'Fix/add connection pools to fix db hangup' directly relates to the main changes in the PR, which add connection pool configurations across multiple database data sources to address database hangup issues.
Description check	✅ Passed	The PR description follows the provided template structure with Issue Number (#638) and lists all change type options, but the 'Type of change' section is not properly checked and 'How the change has been tested' is empty.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
