What is changed and how it works?

Summary:

This PR fixes an issue related to wildcard handling in the scripts/download-integration-test-binaries.sh script, which is used to download and extract required binaries for integration tests in TiCDC. The problem affects systems with certain tar implementations where wildcard matching is not enabled by default, causing the extraction of PD binaries to fail and integration tests to break.

Issue Explanation:

In the current implementation, the following command is used to extract the pd-server.tar.gz package:

tar -xz -C third_bin 'bin/*' -f tmp/pd-server.tar.gz && mv third_bin/bin/* third_bin/

This command uses a wildcard pattern 'bin/*' to match and extract all files within the bin directory of the compressed pd-server.tar.gz archive.

However, not all versions of tar handle wildcard patterns by default. In particular:

• Older or non-GNU versions of tar: These versions do not enable wildcard support unless the --wildcards option is explicitly specified.
• GNU tar: Newer versions of GNU tar generally support wildcards by default, but it's not guaranteed across all environments.

When the script is executed on systems where tar does not natively support wildcard patterns, the command fails to extract the necessary PD executables. As a result:

• The third_bin directory remains empty of PD-related binaries.
• The subsequent integration tests fail due to missing dependencies.

Proposed Solution:

To resolve this issue, I have added the --wildcards option to the tar command in the script, ensuring that wildcard matching works correctly across all versions of tar. Here is the updated command:

tar -xz --wildcards -C third_bin 'bin/*' -f tmp/pd-server.tar.gz && mv third_bin/bin/* third_bin/

By explicitly adding the --wildcards option:

• We ensure consistent behavior of the script across different systems and tar implementations.
• The PD binaries are correctly extracted into the third_bin directory, allowing the integration tests to run successfully.

Steps Taken:

• Updated the tar command in the scripts/download-integration-test-binaries.sh script to include the --wildcards option.
• Verified that the script runs successfully on systems with both GNU tar and non-GNU tar versions.
• Confirmed that the PD binaries are correctly extracted, and the integration tests complete without issues.

Impact:

This fix ensures that the integration test binaries are reliably downloaded and extracted across different environments, preventing failures caused by missing PD executables. This improves the stability and portability of the TiCDC integration tests.

No other parts of the system are affected by this change, and no additional dependencies are introduced.
