test(dm): add DDL option regression coverage

[GMHDBJD]

What problem does this PR solve?

Issue Number: close #12429

DM should continue to accept upstream CREATE TABLE DDLs that include MariaDB-specific table options such as PAGE_CHECKSUM and TRANSACTIONAL, and MySQL-specific table options such as AUTOEXTEND_SIZE.

On current upstream/master, the reported DDL statements are already accepted by the TiDB parser dependency, so the original parser/schema-tracker failure is not reproducible anymore. This PR adds focused regression coverage in DM to prevent this compatibility behavior from regressing.

What is changed and how it works?

• Add parser regression coverage for CREATE TABLE statements using:
  • TRANSACTIONAL=0
  • PAGE_CHECKSUM=1 TRANSACTIONAL=0
  • AUTOEXTEND_SIZE=4M
• Add schema tracker regression coverage for the same DDL patterns and verify the tables/columns are tracked successfully.

Check List

Tests

• Unit test

Commands run:

go test ./dm/pkg/parser -run TestParserSpecificCreateTableOptions -count=1
go test ./dm/pkg/schema -run TestDDLWithSpecificCreateTableOptions -count=1
go test ./dm/pkg/parser ./dm/pkg/schema -count=1
make fmt
git diff --check

Questions

Will it cause performance regression or break compatibility?

No. This PR only adds regression tests and does not change runtime behavior.

Do you need to update user documentation, design documentation or monitoring documentation?

No. This PR only adds regression test coverage for existing compatible behavior.

None

Code Review

This pull request introduces new unit tests to verify the parsing and tracking of DDLs with specific CREATE TABLE options, such as 'transactional=0', 'PAGE_CHECKSUM=1', and 'AUTOEXTEND_SIZE=4M'. Feedback was provided to address a potential loop variable capture issue in the parallel subtests of 'TestParserSpecificCreateTableOptions' to prevent race conditions in Go versions prior to 1.22.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

In Go versions prior to 1.22, referencing the loop variable sql directly inside a parallel subtest (t.Parallel()) causes all subtests to run using the value of the loop variable from the last iteration. To prevent this race condition and ensure all test cases are executed correctly, capture the loop variable sql locally within the loop.
