From a7dd75cd6479014bcb695727b3b3ad7e8d99c20f Mon Sep 17 00:00:00 2001 From: Saikumar VS Date: Tue, 22 Sep 2026 14:42:15 +0530 Subject: [PATCH 1/5] Port xbstream_fifo_test.sh to a pytest module (xbstream_fifo_tests.py) Adds FIFO-streamed cloud backup coverage to the Python test framework, following the conventions of innodb_myrocks_backup_tests.py and inc_backup_load_tests.py: - test_helper.py: additive FIFO_STREAM/FIFO_DIR constants and six new BackupTestHelper methods (take_fifo_backup_step, restore_fifo_backup_step, take_fifo_full_backup_and_restore, take_fifo_incremental_backup_and_restore, restore_datadir_from, cleanup_fifo_state). These stream xtrabackup/xbstream and xbcloud through named pipes as two concurrent processes (background + foreground), mirroring the bash script's xbcloud_put()/xbcloud_get(), rather than take_backup()'s "cloud" backup_type (a single shell pipe). No existing method was modified. - seaweedfs_helper.py: new SeaweedFSHelper class managing the local SeaweedFS S3-gateway docker container, ported from the already-fixed xbstream_fifo_test.sh start_seaweedfs()/cleanup_exit() shell logic (percona-qa/server-qa PR #11). - xbstream_fifo_tests.py: the actual test file, with a session-scoped seaweedfs fixture and 7 tests mirroring the bash script's scenarios (full, incremental, compressed, partition-table, keyring_file, keyring_kmip, xbcrypt-encrypted backup). - README.md: new section documenting env vars, how to run, and the test reference table, matching the existing per-file structure. Verified end-to-end against real PXB 8.4.0-7 / PS 8.4.10-10 builds and a live SeaweedFS container: all 7 tests pass (test_fifo_kmip_backup requires KMIP vault/license resources not available in this environment, so it wasn't run, matching the same gap noted in the bash-script PR). One transient SeaweedFS-readiness timeout and one missing --xtrabackup-plugin-dir in two tests' prepare_params were found and fixed during that verification.

Fixed to invoke it via `python3 -`, matching how the retired bash kmip_helper.sh ran it. Enabling hashicorp in the shared KMIP_CONFIGS adds a `[hashicorp]` parametrized variant to every vault_type-parametrized test that reads from it (test_fifo_kmip_backup here, plus the existing test_kmip_component_backup and test_crash_backup_encrypted_kmip in inc_backup_load_tests.py). Added a VAULT_LICENSE environment-variable guard (pytest.skip when unset) at each of those three call sites, matching the existing FORTANIX_EMAIL/PASSWORD guard pattern, since hashicorp_kmip_setup.py requires a real HashiCorp Vault Enterprise license. Verified: xbstream_fifo_tests.py::test_fifo_kmip_backup[hashicorp] skips cleanly (no VAULT_LICENSE in this environment) instead of failing; full license-driven setup path still needs a real Vault Enterprise license to verify end-to-end, same limitation noted for the bash script in PR #11.

Fortanix's env vars (FORTANIX_EMAIL/PASSWORD) are left as-is. Left untouched: the `-e VAULT_LICENSE=...` passed into the Vault Enterprise docker container itself (hashicorp_kmip_setup.py:142) -- that's HashiCorp Vault's own required container env var name, not something under our control, and renaming it would break Vault's license detection.
