* Once the Logger has been set, for any logging related operations, we have
|
|

|
|
* corresponding callback. The overhead to check for DEBUG and TRACE in each
|
|
* PKIX function entering and exiting is very expensive (400X), and redundant
|
|
* if they are not the interest of the Logger. Therefore, the PKIX_Logger List
|
|
* pkixLoggers is separated into two lists based on its Loggers' trace level.
|
|
*
|
|
* Whenever the pkixLoggers List is updated by PKIX_Logger_AddLogger() or
|
|
* PKIX_Logger_SetLoggers(), we destroy and reconstruct pkixLoggersErrors
|
|
* and pkixLoggersDebugTrace Logger Lists. The ERROR, FATAL_ERROR and
|
|
* WARNING goes to pkixLoggersErrors and the DEBUG and TRACE goes to
|
|
* pkixLoggersDebugTrace.
|
|
*
|
|
* Currently we provide five logging levels and the default setting are by:
|
|
*
|
|
* PKIX_FATAL_ERROR() macro invokes pkix_Logger_Check of FATAL_ERROR level
|
|
* PKIX_ERROR() macro invokes pkix_Logger_Check of ERROR level
|
|
* WARNING is not invoked as default
|
|
* PKIX_DEBUG() macro invokes pkix_Logger_Check of DEBUG level. This needs
|
|
* compilation -DPKIX_<component>DEBUG flag to turn on
|
|
* PKIX_ENTER() and PKIX_RETURN() macros invoke pkix_Logger_Check of TRACE
|
|
* level. TRACE provides duplicate information of DEBUG, but needs no
|
|
* recompilation and cannot choose component. To allow application
|
|
* to use DEBUG level, TRACE is put as last.

* FUNCTION: pkix_Logger_CheckErrors
|
|
* DESCRIPTION:
|
|
*
|
|
* This function goes through each PKIX_Logger at "pkixLoggersList" and
|
|
* checks if "maxLevel" and "logComponent" satisfies what is specified in the
|
|
* PKIX_Logger. If satisfies, it invokes the callback in PKIX_Logger and
|
|
* passes a PKIX_PL_String that is the concatenation of "message" and
|
|
* "message2" to the application for processing.
|
|
* Since this call is inserted into a handful of PKIX macros, no macros are
|
|
* applied in this function, to avoid infinite recursion.
|
|
* If an error occurs, this call is aborted.
|
|
*
|
|
* PARAMETERS:
|
|
* "pkixLoggersList"
|
|
* A list of PKIX_Loggers to be examined for invoking callback. Must be
|
|
* non-NULL.
|
|
* "message"
|
|
* Address of "message" to be logged. Must be non-NULL.
|
|
* "message2"
|
|
* Address of "message2" to be concatenated and logged. May be NULL.
|
|
* "logComponent"
|
|
* A PKIX_UInt32 that indicates the component the message is from.
|
|
* "maxLevel"
|
|
* A PKIX_UInt32 that represents the level of severity of the message.
|
|
* "plContext"
|
|
* Platform-specific context pointer.
|
|
* THREAD SAFETY:
|
|
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
|
|
* RETURNS:
|
|
* Returns NULL if the function succeeds
|
|
* Returns a Fatal Error if the function fails in an unrecoverable way
