Project goal: pure-Python implementation of the Informix SQLI wire protocol. No CSDK, no JVM, no native deps. Targets icr.io/informix /informix-developer-database (port 9088) as the dev/test instance. Phase 0 is a documentation-only spike that gates all implementation work. The four scaffolds: - README.md: project status and Phase 0 deliverable index - docs/PROTOCOL_NOTES.md: byte-level wire-format reference (TBD) - docs/JDBC_NOTES.md: reverse-lookup index into the decompiled IBM JDBC driver (4.50.4.1), populated from build/jdbc-src/ once the decompile lands - docs/DECISION_LOG.md: running rationale, with the Phase-1 paramstyle /Python-floor/autocommit decisions pre-locked so they don't churn later CLAUDE.md is gitignored — operator-private context, public-PyPI repo.
informix-db
Pure-Python driver for IBM Informix IDS, speaking the SQLI wire protocol over raw sockets. No IBM Client SDK. No JVM. No native libraries.
Status
🚧 Phase 0 — Spike. Characterizing the SQLI wire protocol. No library code yet.
The protocol has never been published byte-for-byte by IBM. Every existing Informix driver in every language wraps either IBM's CSDK or the JDBC JAR. This project closes that gap.
Phase 0 deliverables
docs/PROTOCOL_NOTES.md— byte-level wire-format reference, derived from packet captures + JDBC decompilationdocs/JDBC_NOTES.md— index into the decompiled IBM JDBC driver's wire-protocol classesdocs/DECISION_LOG.md— running rationale for protocol/auth/type decisionsdocs/CAPTURES/*.pcap— annotated packet captures of reference exchanges
If Phase 0's exit criteria are met, library implementation begins in Phase 1.
Test target
icr.io/informix/informix-developer-database (port 9088, native SQLI). See tests/docker-compose.yml once Phase 1 lands.
