2025-06 Monthly Summary (percona/pg_tde and percona/postgres) Key features delivered - Vault provider enhancements and documentation for pg_tde: added HTTPS guidance in docs, unified argument order across KMIP and Vault providers, and tests ensuring Vault CA path is optional for pg_tde_change_key_provider. - Keyring cleanup and refactoring: cleanup of static functions in tde_keyring.c, improved KeyringGenerateNewKey handling, upgrade to OpenTransientFile for safer I/O, and header/struct hygiene improvements. - Partitioned Index Encryption: PG-1663 ensures indexes on partitioned tables are encrypted. Major bugs fixed - Key retrieval and provider-change fixes: return all nulls for key info when no key exists; do not fetch from old provider when changing provider settings; corrected string handling and header/implementation argument naming. - Shared memory cleanup and access method handling: fixed shared memory cleanup merge issue and standardized handling that not finding a key in the provider is a success; corrected changes to partitioned table access method. - TAP tests stability and pre-test handling: ensure key files are deleted before TAP tests; switch test start strategy to polling (poll_start). - Frontend handling and table encryption workflows: remove frontend handling from pg_tde_guc; ensure encryption of indexes on partitioned tables and correct access method changes. Overall impact and accomplishments - Strengthened security and reliability of the TDE workflow through improved Vault integration and robust keyring management. - Reduced maintenance overhead via comprehensive code cleanup, API hygiene, and formatting improvements. - Increased confidence in deployment and test stability with enhanced TAP test practices and pre-test cleanup. Technologies/skills demonstrated - C development for PostgreSQL extensions; memory management and zero-initialization standards. - Vault/KMIP integration and secure key provisioning workflows. - Code hygiene: header/implementation alignment, safe file I/O patterns, and modernizing access checks. - Testing practices: improved TAP test reliability and pre-test cleanup procedures.
