Move sqllogictests to sqllogictests crate to break cyclic dependency #7284

alamb · 2023-08-14T22:21:05Z

Which issue does this PR close?

Closes #7281

Rationale for this change

feat: add sqllogictests crate #7134 introduced a circular dependency which means we can't publish to crates.io
Elevating the sqllogictests into a less deep directory hierarchy will make it more discoverable

What changes are included in this PR?

Move sqllogictest drivers from datafusion/core/tests/sqlloictest to datafusion/sqllogictest
Update TestContext and include it in the datafusion_sqllogictest module
Update CI jobs that use sqllogictest to use the new module
Update readme
Leave backwards compatibility MOVED.md

Are these changes tested?

Yes, both manually and via CI

Are there any user-facing changes?

No, but this likely will affect developer tests

New Command

sqllogictest, is now run like this:

cargo test --test sqllogictest

The old command was like this

cargo test -p datafusion --test sqllogictest

Bonus it also fixes the error called out by @Dandandan in the mailing list thread: https://lists.apache.org/thread/mbm8smv4rombbbsnfgll922768b103z6

.github/workflows/dev_pr/labeler.yml

  - datafusion/substrait/**/*

 sqllogictest:
-  - datafusion/core/tests/sqllogictests/**/*


This illustrates that the sqllogictest code is no longer so deeply nested in the tree, which I think is a good change overall

alamb · 2023-08-15T10:36:50Z

.github/workflows/rust.yml

          rustup default stable
      - name: Run sqllogictest
-        run: PG_COMPAT=true PG_URI="postgresql://postgres:postgres@localhost:$POSTGRES_PORT/db_test" cargo test -p datafusion --test sqllogictests
+        run: PG_COMPAT=true PG_URI="postgresql://postgres:postgres@localhost:$POSTGRES_PORT/db_test" cargo test --features=postgres --test sqllogictests


Now running the posgres compatibility tests requires a feature flag, which I think is a good thing and will speed up normal developer workflows

alamb · 2023-08-15T10:37:01Z

.github/workflows/rust.yml

+          export TPCH_DATA=`realpath datafusion/sqllogictest/test_files/tpch/data`
          cargo test serde_q --profile release-nonlto --features=ci -- --test-threads=1
-          INCLUDE_TPCH=true cargo test -p datafusion --test sqllogictests
+          INCLUDE_TPCH=true cargo test --test sqllogictests


Arguable it is easier to run these tests now

alamb · 2023-08-15T10:37:27Z

datafusion/core/Cargo.toml

 criterion = { version = "0.5", features = ["async_tokio"] }
 csv = "1.1.6"
 ctor = "0.2.0"
-datafusion-sqllogictest = { path = "../sqllogictest", version = "29.0.0", features = ["postgres"] }


Removing this line to remove the circular dependency is the entire reason for this PR

alamb · 2023-08-15T10:38:31Z

datafusion/sqllogictest/Cargo.toml

 tokio = {version = "1.0"}
 bytes = {version = "1.4.0", optional = true}
-futures = {version = "0.3.28", optional = true}
+futures = {version = "0.3.28"}


datafusion depends on futures anyways so this is not a new dependency

alamb · 2023-08-15T10:39:36Z

datafusion/sqllogictest/bin/sqllogictests.rs

    } = test_file;
    info!("Running with DataFusion runner: {}", path.display());
-    let Some(test_ctx) = context_for_test_file(&relative_path).await else {
+    let Some(test_ctx) = TestContext::try_new_for_test_file(&relative_path).await else {


I moved the logic for creating TestContext into the datafusion_sqllogictest library (and out of the runner) to avoid making the runner even longer

datafusion/sqllogictest/bin/sqllogictests.rs

    )
 }

-/// Create a SessionContext, configured for the specific test, if


moved to test_context.rs

datafusion/sqllogictest/test_files/array.slt


 statement ok
-CREATE EXTERNAL TABLE fixed_size_list_array STORED AS PARQUET LOCATION 'tests/data/fixed_size_list_array.parquet';
+CREATE EXTERNAL TABLE fixed_size_list_array STORED AS PARQUET LOCATION '../core/tests/data/fixed_size_list_array.parquet';


Eventually it might make sense to move the data files, but for now I just updated the test paths

I only briefly skimmed through the change. Removing the cyclic dependency looks sane to me.
