Date: Thu, 02 Apr 2026 12:25:39 +0000
Message-ID: <E1w8H7C-002bgT-3C@gemulon.postgresql.org> (raw)
perl tap: Show failed command output
Capture stdout and stderr from command_ok() and command_fails() and emit
them as TAP diagnostics on failure. Output is truncated to the first
and last 30 lines per channel to avoid flooding.
A new helper _diag_command_output() is introduced in Utils.pm so
both functions share the same truncation and formatting logic.
