remove lots of depricated files. move some files to appropriate directories (pcertdb *_rand associated headers to soft token, for instance) rename several stan files which had the same name as other nss files. remove depricated functions.

** nssilock.h - Instrumented locking functions for NSS
|
|
**
|
|
** Description:
|
|
** nssilock provides instrumentation for locks and monitors in
|
|
** the NSS libraries. The instrumentation, when enabled, causes
|
|
** each call to the instrumented function to record data about
|
|
** the call to an external file. The external file
|
|
** subsequently used to extract performance data and other
|
|
** statistical information about the operation of locks used in
|
|
** the nss library.
|
|
**
|
|
** To enable compilation with instrumentation, build NSS with
|
|
** the compile time switch NEED_NSS_ILOCK defined.
|
|
**
|
|
** say: "gmake OS_CFLAGS+=-DNEED_NSS_ILOCK" at make time.
|
|
**
|
|
** At runtime, to enable recording from nssilock, one or more
|
|
** environment variables must be set. For each nssILockType to
|
|
** be recorded, an environment variable of the form NSS_ILOCK_x
|
|
** must be set to 1. For example:
|
|
**
|
|
** set NSS_ILOCK_Cert=1
|
|
**
|
|
** nssilock uses PRLOG is used to record to trace data. The
|
|
** PRLogModule name associated with nssilock data is: "nssilock".
|
|
** To enable recording of nssilock data you will need to set the
|
|
** environment variable NSPR_LOG_MODULES to enable
|
|
** recording for the nssilock log module. Similarly, you will
|
|
** need to set the environment variable NSPR_LOG_FILE to specify
|
|
** the filename to receive the recorded data. See prlog.h for usage.
|
|
** Example:
|
|
**
|
|
** export NSPR_LOG_MODULES=nssilock:6
|
|
** export NSPR_LOG_FILE=xxxLogfile
|
|
**
|
|
** Operation:
|
|
** nssilock wraps calls to NSPR's PZLock and PZMonitor functions
|
|
** with similarly named functions: PZ_NewLock(), etc. When NSS is
|
|
** built with lock instrumentation enabled, the PZ* functions are
|
|
** compiled into NSS; when lock instrumentation is disabled,
|
|
** calls to PZ* functions are directly mapped to PR* functions
|
|
** and the instrumentation arguments to the PZ* functions are
|
|
** compiled away.
|
|
**
|
|
**
|
|
** File Format:
|
|
** The format of the external file is implementation
|
|
** dependent. Where NSPR's PR_LOG() function is used, the file
|
|
** contains data defined for PR_LOG() plus the data written by
|
|
** the wrapped function. On some platforms and under some
|
|
** circumstances, platform dependent logging or
|
|
** instrumentation probes may be used. In any case, the
|
|
** relevant data provided by the lock instrumentation is:
|
|
**
|
|
** lockType, func, address, duration, line, file [heldTime]
|
|
**
|
|
** where:
|
|
**
|
|
** lockType: a character representation of nssILockType for the
|
|
** call. e.g. ... "cert"
|
|
**
|
|
** func: the function doing the tracing. e.g. "NewLock"
|
|
**
|
|
** address: address of the instrumented lock or monitor
|
|
**
|
|
** duration: is how long was spent in the instrumented function,
|
|
** in PRIntervalTime "ticks".
|
|
**
|
|
** line: the line number within the calling function
|
|
**
|
|
** file: the file from which the call was made
|
|
**
|
|
** heldTime: how long the lock/monitor was held. field
|
|
** present only for PZ_Unlock() and PZ_ExitMonitor().
|
|
**
|
|
** Design Notes:
|
|
** The design for lock instrumentation was influenced by the
|
|
** need to gather performance data on NSS 3.x. It is intended
|
|
** that the effort to modify NSS to use lock instrumentation
|
|
** be minimized. Existing calls to locking functions need only
|
|
** have their names changed to the instrumentation function
|
|
** names.
|
|
**
|
|
** Private NSS Interface:
|
|
** nssilock.h defines a private interface for use by NSS.
|
|
** nssilock.h is experimental in nature and is subject to
|
|
** change or revocation without notice. ... Don't mess with
|
|
** it.
