Locally, the submodule directory is replaced with a symlink to the existing checkout at `/home/fpawlowski/repo/universal-driver` to avoid a redundant clone. The symlink is added to `.gitignore` so git does not attempt to track it as a file; the submodule reference is tracked via `.gitmodules` and the commit SHA in the index. + +--- + +### 2026-03-09 — Datasource collection errors — two-part fix + +**Decision:** (a) Append stub empty-dict names to `tests/parameters.py`; (b) use `--ignore=tests/integ/datasource` for local runs. + +**Rationale:** Several test files in `tests/integ/datasource/` do a top-level `from tests.parameters import MYSQL_CONNECTION_PARAMETERS` that fails at collection when the names are absent. Additionally, `tests/resources/test_data_source_dir/test_jdbc_data.py` subscripts the dicts at module load (`ORACLEDB_CONNECTION_PARAMETERS["host"]` etc.), which cannot be made safe by stubs alone. The real values are injected in CI by `decrypt_parameters.sh`. Locally: (a) stubs make the names importable for any non-datasource test that references them, and (b) `--ignore=tests/integ/datasource` prevents the `test_jdbc_data.py` module-level subscript from running. In CI the datasource directory is not ignored — the full real parameters are available. + +**Stub parameters added to `tests/parameters.py`:** +- `DATABRICKS_CONNECTION_PARAMETERS = {}` +- `MYSQL_CONNECTION_PARAMETERS = {}` +- `POSTGRES_CONNECTION_PARAMETERS = {}` +- `ORACLEDB_CONNECTION_PARAMETERS = {}` +- `SQL_SERVER_CONNECTION_PARAMETERS = {}` + +--- + +### 2026-03-09 — Fix OpenTelemetry collection errors + +**Decision:** Guard OTel imports at module level in two test files. + +**`tests/integ/test_open_telemetry.py`:** Had unconditional `from opentelemetry import trace` at module level — fails before any `pytestmark` skip markers can apply.

Snowpark's `setup.py` has the constraint `>=3.17.0, <5.0.0` targeting `snowflake-connector-python` by name. After the swap, pip metadata is technically inconsistent (snowpark "requires" a package that isn't installed), but the Python runtime works because `snowflake.connector` is present via the UD package.

Several existing Snowflake ecosystem projects (snowflake-cli, snowfort) depend on legacy `snowflake.connector` symbols (`execute_string`, `DictCursor`, `SnowflakeConnection`, `fetchmany`, `config_manager`, `SnowflakeRestful`, `split_statements`, `compat.py`, `constants.py` enums, key-pair auth) that the UD `main` branch does not yet expose. + +**Hypothesis (confirmed):** A compatibility-focused UD branch exists that backfills these symbols as thin wrappers over the Rust core. + +**Finding:** Branch `turbaszek-ecosystem-compatibility-cli` on `snowflakedb/universal-driver` (24 commits ahead of `main` at time of writing) adds: +- `execute_string`, `execute_stream` +- `DictCursor`, `SnowflakeConnection` alias +- `fetchmany`, `config_manager`, `SnowflakeRestful`, `split_statements` +- `compat.py`, `constants.py` enums +- Key-pair auth + +**Decision:** Created `snowpark-compatibility` branch in the `universal-driver` submodule, branching from `turbaszek-ecosystem-compatibility-cli`. This is the branch used for all local test runs and future CI targeting. Reason for a separate branch rather than tracking the upstream directly: lets us add snowpark-specific patches without polluting the upstream compat branch. + +**Notable difference from `main`:** This branch uses `rustls = { version = "0.23.20", features = ["aws_lc_rs"] }` (same as main, no `"fips"` feature). Also carries `openssl = "0.10.73"` and `jwt = { version = "0.16.0", features = ["openssl"] }` as direct dependencies in `sf_core/Cargo.toml`, which link dynamically against the system's `libssl.so.3`. + +--- + +### 2026-03-10 — Local wheel build: environment issues and fixes + +#### Issue 1: FIPS delocator (resolved — not applicable to this branch) + +**Hypothesis (wrong):** The `turbaszek-ecosystem-compatibility-cli` branch enables the `fips` feature on `rustls`, pulling in `aws-lc-fips-sys` which requires a Go-based delocator tool. On aarch64 Amazon/Rocky Linux with devtoolset-10 GCC 10.2.1, the delocator produces `parse error near WS` on the generated assembly. + +**Correction:** The `snowpark-compatibility` branch (`turbaszek-ecosystem-compatibility-cli` base) does **not** have `"fips"` in `rustls` features and `aws-lc-fips-sys` is absent from `Cargo.lock`. This issue does not apply. The hypothesis was formed while investigating an earlier branch state. + +#### Issue 2: `cmake` not found inside `uv run` subprocess + +**Observation:** Running `uv run --with hatch ... hatch build` failed with `Missing dependency: cmake`. `/usr/bin/cmake` exists on the system but is not on the `PATH` visible to the `cargo` subprocess spawned from within `uv`'s isolated environment on Rocky Linux 9.7. + +**Fix:** Pass `CMAKE=/usr/bin/cmake` as an explicit env var (the `aws-lc-sys` build script checks `$CMAKE` before searching `PATH`). Added to `scripts/build_ud_connector.sh`: +```bash +CMAKE="${CMAKE:-$(command -v cmake 2>/dev/null)}" \ + uv run --with hatch --with cython --with setuptools hatch build +``` +On systems where cmake is on PATH (e.g. Ubuntu CI), `command -v cmake` resolves it and the env var is a no-op. + +**Outcome (observation):** Wheel built successfully: +``` +dist/snowflake_connector_python_ud-0.1.0-py3-none-any.whl +``` +Contains `libsf_core.so` (55 MB unstripped release build) and `arrow_stream_iterator.cpython-310-aarch64-linux-gnu.so`. The `py3-none-any` tag is cosmetic — hatchling doesn't auto-tag platform wheels when binaries are injected via build hooks. + +#### Issue 3: `libssl.so.3` not found at runtime (OPEN) + +**Observation:** After installing the wheel into the tox venv, importing `snowflake.connector` fails with `RuntimeError: Couldn't load core driver dependency`. Root cause: `libsf_core.so` was compiled against system OpenSSL 3.5.1 (`/lib64/libssl.so.3`) because `openssl-sys` detects it via pkg-config. The tox venv uses the nix-managed Python interpreter (`/opt/sfc/python3.10`), which runs with `LD_LIBRARY_PATH` pointing exclusively to nix store paths. Those paths contain only OpenSSL 1.1.x (`libssl.so.1.1`), not 3.x. + +**Hypothesis A (tested, failed):** Add `/lib64` to `LD_LIBRARY_PATH`. Result: nix bash (glibc 2.34) collides with system `libc.so.6` (requires GLIBC_2.35) — the two glibc stacks cannot be mixed. + +**Hypothesis B (tested, failed):** `OPENSSL_STATIC=1` during cargo build. Result: linker still emits `-Wl,-Bdynamic -lssl -lcrypto`. `OPENSSL_STATIC=1` did not propagate into the `openssl-sys` build script subprocess. Static `.a` files may also be absent. + +**Hypothesis C (not yet tested):** `RUSTFLAGS="-C link-arg=-Wl,-rpath,/lib64"` embeds `/lib64` into the `.so` RPATH. Since RPATH is consulted before `LD_LIBRARY_PATH`, this would let nix Python find `libssl.so.3` without mixing glibc stacks. + +**Hypothesis D (not yet tested):** Copy `libssl.so.3` and `libcrypto.so.3` from `/lib64` into the wheel's `_core/` directory next to `libsf_core.so`. The existing `$ORIGIN` RPATH would find them. Avoids any rebuild. Requires bundling ~5 MB of system libs in the local wheel; CI wheels are built on Ubuntu where this issue does not arise. + +**Open question:** Which of C or D is the right fix? D is simpler for local dev but potentially violates OpenSSL licensing/distribution expectations if the wheel were ever published. C is cleaner but requires a rebuild. + +--- + +--- + +### 2026-03-11 — Env fixes: libssl.so.3 (resolved), GLIBCXX_3.4.29 (resolved), missing symbols (resolved) + +#### libssl.so.3 — Hypothesis D confirmed + +**Conclusion:** Copying `/lib64/libssl.so.3` and `/lib64/libcrypto.so.3` into the wheel's `_core/` directory resolves the `RuntimeError: Couldn't load core driver dependency` failure. The `$ORIGIN` RPATH on `libsf_core.so` causes the dynamic linker to find the bundled copies before consulting `LD_LIBRARY_PATH`. Implemented in `scripts/build_ud_connector.sh` as a conditional post-build step (no-op on Ubuntu CI where `libssl.so.3` is on the default search path). + +**Note:** `libssl.so.3` and `libcrypto.so.3` require GLIBC up to 2.34; the nix Python uses GLIBC_2.34, so no collision. + +#### GLIBCXX_3.4.29 — new blocker (resolved via LD_PRELOAD) + +**Observation:** After libssl was fixed, the next error was: +``` +ImportError: /nix/store/.../gcc-9.3.0-lib/lib/libstdc++.so.6: version 'GLIBCXX_3.4.29' not found +(required by snowflake/connector/_internal/arrow_stream_iterator.cpython-310-aarch64-linux-gnu.so) +``` + +**Root cause (observation):** `arrow_stream_iterator.so` was compiled against the system GCC (GLIBCXX_3.4.29). The nix Python environment loads the nix gcc-9.3.0 libstdc++ first (via pyarrow importing it), which only has GLIBCXX up to 3.4.28. The `$ORIGIN` trick is ineffective here because `libstdc++.so.6` is already loaded in the process image before `arrow_stream_iterator.so` is imported. + +**$ORIGIN approach (hypothesis E, tested, failed):** Copying `/usr/lib64/libstdc++.so.6` into `_internal/` alongside the .so did not help — the already-loaded nix version wins the soname race. + +**Fix (hypothesis F — confirmed):** `LD_PRELOAD=/usr/lib64/libstdc++.so.6` forces the system libstdc++ to be loaded before the nix Python environment loads its own. The system `libstdc++.so.6` requires GLIBC_2.34 (not 2.35), so no glibc collision occurs. Implemented in `scripts/run_tests_with_ud.sh` (conditional, no-op where `/usr/lib64/libstdc++.so.6` is absent) and `LD_PRELOAD` added to `passenv` in `tox.ini`. + +#### Missing Python symbols — resolved + +**Observation:** After env fixes, Snowpark could not be imported due to missing symbols in the UD connector.

This change was NOT committed. + +**Hypothesis (unconfirmed — exact error not recorded):** The working-tree removal was applied to silence a local build failure. `aws-lc-fips-sys` requires `cmake` and a Go-based delocator at build time. The probable failure mode is category: **Build failure** — `cmake` or the delocator was unavailable during a local build attempt on the Rocky Linux / aarch64 build host. The same issue was documented for the `turbaszek-ecosystem-compatibility-cli` branch in "Issue 1" above, and `cmake` unavailability was separately documented as "Issue 2" in the same section. The connection between FIPS and cmake is well-supported by context, but the exact cargo/cmake error output was not captured at the time. + +**Note on earlier ADR section ("Issue 1 — FIPS delocator — resolved — not applicable"):** That section stated the `snowpark-compatibility` branch does not have `"fips"` features. This is now contradicted by the committed branch state. The earlier statement was accurate when written (it described the `turbaszek-ecosystem-compatibility-cli` base), but the `snowpark-compatibility` branch diverged and the `"fips"` feature appears in its current commits (introduced by `63e04d74` or earlier snowpark-specific commits). The "resolved — not applicable" label in Issue 1 applies to the base branch as originally described, not to the current `snowpark-compatibility` HEAD. The working-tree removal is the correct local workaround; the committed state carries the FIPS dependency. + +**Decision:** The working-tree modification (FIPS removal) is being reverted. The committed state is left as-is. + +**Deferred — real fix required:** The `snowpark-compatibility` branch carries `"fips"` in rustls, which adds a build-time dependency on `cmake` and `aws-lc-fips-sys`. For local development on aarch64 / Rocky Linux where cmake is unavailable in the cargo subprocess PATH, this will continue to cause build failures. The real fix has two candidates: +1. Remove `"fips"` from `rustls` in `sf_core/Cargo.toml` in a proper commit on `snowpark-compatibility` with rationale — this is valid if FIPS is not required for Snowpark CI targets. +2. Ensure cmake is available on the PATH in the cargo subprocess during local builds (extend the `CMAKE=...` env var approach in `build_ud_connector.sh` to also cover the FIPS delocator). + +**Scope ruling:** This fix is out of scope for the current task (Phase 5 — test collection).
