Overview

Reports fatal errors related to conditional statement processing in pgbench scripts.

Definition

static void ConditionError(const char *desc, int cmdn, const char *msg)

Detailed Description

This is a specialized error reporting function for conditional statement errors in pgbench benchmark scripts. It formats and displays a fatal error message that includes the script description, command number, and specific error message, then terminates the program. The function is specifically designed to handle errors in if/elif/else/endif conditional constructs.

Parameters / Member Variables

  • desc: Description or name of the script being processed
  • cmdn: Command number where the error occurred (for pinpointing location)
  • msg: Specific error message describing what went wrong

Dependencies

  • Functions called/Symbols referenced:
    • pg_fatal (implicitly terminates program)
  • Called from:
    • CheckConditional (multiple calls at src/bin/pgbench/pgbench.c:5910, 5912, 5916, 5918, 5923, 5932)

Notes and Other Information

  • This is a fatal error function that does not return to caller
  • Part of pgbench's conditional statement validation system
  • Provides structured error reporting for script debugging
  • The error message format includes script name and command number for precise error location
  • Used exclusively by CheckConditional function for various conditional syntax errors

Simplified Source

static void ConditionError(const char *desc, int cmdn, const char *msg) {
    // Report fatal conditional error with script context
    pg_fatal("condition error in script \"%s\" command %d: %s",
             desc, cmdn, msg);
}
