Assure

Assure2((condition), #condition)

Like assert() but throws an exception instead of aborting the process. Use this macro to detect code logic mistakes (i.e. bugs) where aborting the current AsyncJob or a similar task is unlikely to jeopardize Squid service integrity. For example, this macro is not appropriate for detecting bugs that indicate a dangerous global state corruption which may go unnoticed by other jobs after the current job or task is aborted.

Assure2

#define Assure2	(		condition,
			description
	)		Assure_(0, (condition), ("assurance failed: " description), Here())

Like Assure() but allows the caller to customize the exception message.

Parameters

description

string literal describing the condition (i.e. what MUST happen)

Definition at line 40 of file Assure.h.

Assure_

#define Assure_	(		debugLevel,
			condition,
			description,
			location
	)

Value:

    while (!(condition)) \
        ReportAndThrow_((debugLevel), (description), (location))

Calls ReportAndThrow() if needed. Reduces caller code duplication. Do not call directly; use Assure() instead.

Parameters

description

c-string explaining the condition (i.e. what MUST happen)

Definition at line 23 of file Assure.h.

Function Documentation

ReportAndThrow_()

void ReportAndThrow_	(	int	debugLevel,
		const char *	description,
		const SourceLocation &	location
	)

Reports the description (at the given debugging level) and throws the corresponding exception. Reduces compiled code size of Assure() and Must() callers. Do not call directly; use Assure() instead.

Parameters

description

explains the condition (i.e. what MUST happen)
