-** 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. |
