+INTRODUCTION
 
-Output of profile.run(statement) and of the print_stats() method of
-the `Stats' class consists of the following fields.
+A "profiler" is a program that describes the run time performance of a
+program, providing a variety of statistics.  This documentation
+describes the profiler functionality provided in the modules
+"profile" and "pstats."  This profiler provides "deterministic
+profiling" of any Python programs.  It also provides a series of
+report generation tools to allow users to rapidly examine the results
+of a profile operation.
 
-	Number of times the function was called.
-	Total time spent in the function.
-	Mean time per function call (second field divided by first).
-	Total time spent in the function and all functions it called,
-		recursively.
-	Mean time time spent in the function and all functions it
-		called (fourth field divided by first).
-	Name of the function in the format
-		<file name>:<line number>(<function name>)
 
-The output of the print_callers and print_callees methods consists of
-the name of the function and the names of all function it called or
-was called from.  The latter names are followed by a parenthesised
-number which is the number of calls for this function.
+HOW IS THIS profile DIFFERENT FROM THE OLD profile MODULE?
+
+The big changes from standard profiling module are that you get more
+information, and you pay less CPU time.  It's not a trade-off, it's a
+trade-up.
+
+To be specific:
+
+ bugs removed: local stack frame is no longer molested, execution time
+      is now charged to correct functions, ....
+
+ accuracy increased: profiler execution time is no longer charged to
+      user's code, calibration for platform is supported, file reads
+      are not done *by* profiler *during* profiling (and charged to
+      user's code!), ...
+
+ speed increased: Overhead CPU cost was reduced by more than a factor of
+      two (perhaps a factor of five), lightweight profiler module is
+      all that must be loaded, and the report generating module
+      (pstats) is not needed during profiling. 
+
+ recursive functions support: cumulative times in recursive functions
+      are correctly calculated; recursive entries are counted; ...
+
+ large growth in report generating UI: distinct profiles runs can be added
+       together forming a comprehensive report; functions that import
+       statistics take arbitrary lists of files; sorting criteria is now
+       based on keywords (instead of 4 integer options); reports shows
+       what functions were profiled as well as what profile file was
+       referenced; output format has been improved, ...
+
+
+INSTANT USERS MANUAL
+
+This section is provided for users that "don't want to read the
+manual." It provides a very brief overview, and allows a user to
+rapidly perform profiling on an existing application.
+
+To profile an application with a main entry point of "foo()", you
+would add the following to your module:
+
+	import profile
+	profile.run("foo()")
+
+The above action would cause "foo()" to be run, and a series of
+informative lines (the profile) to be printed.  The above approach is
+most useful when working with the interpreter.  If you would like to
+save the results of a profile into a file for later examination, you
+can supply a file name as the second argument to the run() function:
+
+	import profile
+	profile.run("foo()", 'fooprof')
+
+When you wish to review the profile, you should use the methods in the
+pstats module.  Typically you would load the statistics data as
+follows:
+
+	import pstats
+	p = pstats.Stats('fooprof')
+
+The class "Stats" (the above code just created an instance of this
+class) has a variety of methods for manipulating and printing the data
+that was just read into "p".  When you ran profile.run() above, what
+was printed was the result of three method calls:
+
+	p.strip_dirs().sort_stats(-1).print_stats()
+
+The first method removed the extraneous path from all the module
+names. The second method sorted all the entries according to the
+standard module/line/name string that is printed (this is to comply
+with the semantics of the old profiler).  The third method printed out
+all the statistics.  You might try the following sort calls:
+
+	p.sort_stats('name')
+	p.print_stats()
+
+The first call will actually sort the list by function name, and the
+second call will print out the statistics.  The following are some
+interesting calls to experiment with:
+
+	p.sort_stats('cumulative').print_stats(10)
+
+This sorts the profile by cumulative time in a function, and then only
+prints the ten most significant lines.  If you want to understand what
+algorithms are taking time, the above line is what you would use.
+
+If you were looking to see what functions were looping a lot, and
+taking a lot of time, you would do:
+
+	p.sort_stats('time').print_stats(10)
+
+to sort according to time spent within each function, and then print
+the statistics for the top ten functions.
+
+You might also try:
+
+	p.sort_stats('file').print_stats('__init__')
+
+This will sort all the statistics by file name, and then print out
+statistics for only the class init methods ('cause they are spelled
+with "__init__" in them).  As one final example, you could try:
+
+	p.sort_stats('time', 'cum').print_stats(.5, 'init')
+
+This line sorts stats with a primary key of time, and a secondary key
+of cumulative time, and then prints out some of the statistics.  To be
+specific, the list is first culled down to 50% (re: .5) of its
+original size, then only lines containing "init" are maintained, and
+that sub-sub-list is printed.
+
+If you wondered what functions called the above functions, you could
+now (p is still sorted according to the last criteria) do:
+
+	p.print_callers(.5, 'init')
+
+and you would get a list of callers for each of the listed functions. 
+
+If you want more functionality, you're going to have to read the
+manual (or guess) what the following functions do:
+
+	p.print_callees()
+	p.add('fooprof')
+
+
+WHAT IS DETERMINISTIC PROFILING?
+
+"Deterministic profiling" is meant to reflect the fact that all
+"function call", "function return", and "exception" events are
+monitored, and precise timings are made for the intervals between
+these events (during which time the user's code is executing).  In
+contrast, "statistical profiling" (which is not done by this module)
+randomly samples the effective instruction pointer, and deduces where
+time is being spent.  The latter technique traditionally involves less
+overhead (as the code does not need to be instrumented), but provides
+only relative indications of where time is being spent.
+
+In Python, since there is an interpreter active during execution, the
+presence of instrumented code is not required to do deterministic
+profiling. Python automatically provides a hook (optional callback)
+for each event.  In addition, the interpreted nature of Python tends
+to add so much overhead to execution, that deterministic profiling
+tends to only add small processing overhead, in typical applications.
+The result is that deterministic profiling is not that expensive, but
+yet provides extensive run time statistics about the execution of a
+Python program.  
+
+Call count statistics can be used to identify bugs in code (surprising
+counts), and to identify possible inline-expansion points (high call
+counts).  Internal time statistics can be used to identify hot loops
+that should be carefully optimized.  Cumulative time statistics should
+be used to identify high level errors in the selection of algorithms.
+Note that the unusual handling of cumulative times in this profiler
+allows statistics for recursive implementations of algorithms to be
+directly compared to iterative implementations.
+
+
+REFERENCE MANUAL			  
+
+The primary entry point for the profiler is the global function
+profile.run().  It is typically used to create any profile
+information.  The reports are formatted and printed using methods for
+the class pstats.Stats.  The following is a description of all of
+these standard entry points and functions.  For a more in-depth view
+of some of the code, consider reading the later section on "Profiler
+Extensions," which includes discussion of how to derive "better"
+profilers from the classes presented, or reading the source code for
+these modules.
+
+
+FUNCTION	profile.run(string, filename_opt)
+
+This function takes a single argument that has can be passed to the
+"exec" statement, and an optional file name.  In all cases this
+routine attempts to "exec" its first argument, and gather profiling
+statistics from the execution. If no file name is present, then this
+function automatically prints a simple profiling report, sorted by the
+standard name string (file/line/function-name) that is presented in
+each line.  The following is a typical output from such a call:
+
+cut here----
+
+         main()
+         2706 function calls (2004 primitive calls) in 4.504 CPU seconds
+
+   Ordered by: standard name
+
+   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
+        2    0.006    0.003    0.953    0.477 pobject.py:75(save_objects)
+     43/3    0.533    0.012    0.749    0.250 pobject.py:99(evaluate)
+	...
+
+cut here----
+
+The first line indicates that this profile was generated by the call:
+profile.run('main()'), and hence the exec'ed string is 'main()'.  The
+second line indicates that 2706 calls were monitored.  Of those calls,
+2004 were "primitive."  We define "primitive" to mean that the call
+was not induced via recursion.  The next line: "Ordered by: standard
+name", indicates that the text string in the far right column was used
+to sort the output.  The column headings include:
+
+	"ncalls" for the number of calls, 
+	"tottime" for the total time spent in the given function
+		(and excluding time made in calls to sub-functions), 
+	"percall" is the quotient of "tottime" divided by "ncalls"
+	"cumtime" is the total time spent in this and all subfunctions
+		(i.e., from invocation till exit). This figure is
+		accurate *even* for recursive functions.
+	"percall" is the quotient of "cumtime" divided by primitive
+		calls
+	"filename:lineno(function)" provides the respective data of
+		each function
+
+When there are two numbers in the first column (e.g.: 43/3), then the
+latter is the number of primitive calls, and the former is the actual
+number of calls.  Note that when the function does not recurse, these
+two values are the same, and only the single figure is printed.
+
+
+CLASS	Stats(filename, ...)
+
+This class constructor creates an instance of a statistics object from
+a filename (or set of filenames).  Stats objects are manipulated by
+methods, in order to print useful reports.  
+
+The file selected by the above constructor must have been created by
+the corresponding version of profile.  To be specific, there is *NO*
+file compatibility guaranteed with future versions of this profiler,
+and there is no compatibility with files produced by other profilers
+(e.g., the standard system profiler).
+
+If several files are provided, all the statistics for identical
+functions will be coalesced, so that an overall view of several
+processes can be considered in a single report.  If additional files
+need to be combined with data in an existing Stats object, the add()
+method can be used.
+
+
+METHOD	strip_dirs()
+
+This method for the Stats class removes all leading path information
+from file names.  It is very useful in reducing the size of the
+printout to fit within (close to) 80 columns.  This method modifies
+the object, and the striped information is lost.  After performing a
+strip operation, the object is considered to have its entries in a
+"random" order, as it was just after object initialization and
+loading.  If strip_dir() causes two function names to be
+indistinguishable (i.e., they are on the same line of the same
+filename, and have the same function name), then the statistics for
+these two entries are accumulated into a single entry.
+
+
+METHOD	add(filename, ...)
+
+This methods of the Stats class accumulates additional profiling
+information into the current profiling object.  Its arguments should
+refer to filenames created my the corresponding version of
+profile.run().  Statistics for identically named (re: file, line,
+name) functions are automatically accumulated into single function
+statistics.
+
+
+METHOD	sort_stats(key, ...)
+
+This method modifies the Stats object by sorting it according to the
+supplied criteria.  The argument is typically a string identifying the
+basis of a sort (example: "time" or "name").
+
+When more than one key is provided, then additional keys are used as
+secondary criteria when the there is equality in all keys selected
+before them.  For example, sort_stats('name', 'file') will sort all
+the entries according to their function name, and resolve all ties
+(identical function names) by sorting by file name.
+
+Abbreviations can be used for any key names, as long as the
+abbreviation is unambiguous.  The following are the keys currently
+defined: 
+
+		Valid Arg       Meaning
+		  "calls"      call count
+		  "cumulative" cumulative time
+		  "file"       file name
+		  "module"     file name
+		  "pcalls"     primitive call count
+		  "line"       line number
+		  "name"       function name
+		  "nfl"        name/file/line
+		  "stdname"    standard name
+		  "time"       internal time
+
+Note that all sorts on statistics are in descending order (placing most
+time consuming items first), where as name, file, and line number
+searches are in ascending order (i.e., alphabetical). The subtle
+distinction between "nfl" and "stdname" is that the standard name is a
+sort of the name as printed, which means that the embedded line
+numbers get compared in an odd way.  For example, lines 3, 20, and 40
+would (if the file names were the same) appear in the string order
+"20" "3" and "40".  In contrast, "nfl" does a numeric compare of the
+line numbers.  In fact, sort_stats("nfl") is the same as
+sort_stats("name", "file", "line").
+
+For compatibility with the standard profiler, the numeric argument -1,
+0, 1, and 2 are permitted.  They are interpreted as "stdname",
+"calls", "time", and "cumulative" respectively.  If this old style
+format (numeric) is used, only one sort key (the numeric key) will be
+used, and additionally arguments will be silently ignored.
+
+
+METHOD	reverse_order()
+
+This method for the Stats class reverses the ordering of the basic
+list within the object.  This method is provided primarily for
+compatibility with the standard profiler.  Its utility is questionable
+now that ascending vs descending order is properly selected based on
+the sort key of choice.
+
+
+METHOD	print_stats(restriction, ...)
+
+This method for the Stats class prints out a report as described in
+the profile.run() definition.  
+
+The order of the printing is based on the last sort_stats() operation
+done on the object (subject to caveats in add() and strip_dirs()).
+
+The arguments provided (if any) can be used to limit the list down to
+the significant entries.  Initially, the list is taken to be the
+complete set of profiled functions.  Each restriction is either an
+integer (to select a count of lines), or a decimal fraction between
+0.0 and 1.0 inclusive (to select a percentage of lines), or a regular
+expression (to pattern match the standard name that is printed).  If
+several restrictions are provided, then they are applied sequentially.
+For example:
+
+	print_stats(.1, "foo:")
+
+would first limit the printing to first 10% of list, and then only 
+print functions that were part of filename ".*foo:".  In contrast, the
+command: 
+
+	print_stats("foo:", .1)
+
+would limit the list to all functions having file names ".*foo:", and
+then proceed to only print the first 10% of them.
+
+
+METHOD	print_callers(restrictions, ...)
+
+This method for the Stats class prints a list of all functions that
+called each function in the profiled database.  The ordering is
+identical to that provided by print_stats(), and the definition of the
+restricting argument is also identical.  For convenience, a number is
+shown in parentheses after each caller to show how many times this
+specific call was made.  A second non-parenthesized number is the
+cumulative time spent in the function at the right.
+
+
+METHOD	print_callees(restrictions, ...)
+
+This method for the Stats class prints a list of all function that
+were called by the indicated function.  Aside from this reversal of
+direction of calls (re: called vs was called by), the arguments and
+ordering are identical to the print_callers() method.
+
+
+METHOD	ignore()
+
+This method of the Stats class is used to dispose of the value
+returned by earlier methods.  All standard methods in this class
+return the instance that is being processed, so that the commands can
+be strung together.  For example:
+
+pstats.Stats('foofile').strip_dirs().sort_stats('cum').print_stats().ignore()
+
+would perform all the indicated functions, but it would not return
+the final reference to the Stats instance.
+
+
+
+	
+LIMITATIONS
+
+There are two fundamental limitations on this profiler.  The first is
+that it relies on the Python interpreter to dispatch "call", "return",
+and "exception" events.  Compiled C code does not get interpreted,
+and hence is "invisible" to the profiler.  All time spent in C code
+(including builtin functions) will be charged to the Python function
+that was invoked the C code.  IF the C code calls out to some native
+Python code, then those calls will be profiled properly.
+
+The second limitation has to do with accuracy of timing information.
+There is a fundamental problem with deterministic profilers involving
+accuracy.  The most obvious restriction is that the underlying "clock"
+is only ticking at a rate (typically) of about .001 seconds.  Hence no
+measurements will be more accurate that that underlying clock.  If
+enough measurements are taken, then the "error" will tend to average
+out. Unfortunately, removing this first error induces a second source
+of error...
+
+The second problem is that it "takes a while" from when an event is
+dispatched until the profiler's call to get the time actually *gets*
+the state of the clock.  Similarly, there is a certain lag when
+exiting the profiler event handler from the time that the clock's
+value was obtained (and then squirreled away), until the user's code
+is once again executing.  As a result, functions that are called many
+times, or call many functions, will typically accumulate this error.
+The error that accumulates in this fashion is typically less than the
+accuracy of the clock (i.e., less than one clock tick), but it *can*
+accumulate and become very significant.  This profiler provides a
+means of calibrating itself for a give platform so that this error can
+be probabilistically (i.e., on the average) removed.  After the
+profiler is calibrated, it will be more accurate (in a least square
+sense), but it will sometimes produce negative numbers (when call
+counts are exceptionally low, and the gods of probability work against
+you :-). )  Do *NOT* be alarmed by negative numbers in the profile.
+They should *only* appear if you have calibrated your profiler, and
+the results are actually better than without calibration.
+
+
+CALIBRATION
+
+The profiler class has a hard coded constant that is added to each
+event handling time to compensate for the overhead of calling the time
+function, and socking away the results.  The following procedure can
+be used to obtain this constant for a given platform (see discussion
+in LIMITATIONS above). 
+
+	import profile
+	pr = profile.Profile()
+	pr.calibrate(100)
+	pr.calibrate(100)
+	pr.calibrate(100)
+
+The argument to calibrate() is the number of times to try to do the
+sample calls to get the CPU times.  If your computer is *very* fast,
+you might have to do:
+
+	pr.calibrate(1000)
+
+or even:
+
+	pr.calibrate(10000)
+
+The object of this exercise is to get a fairly consistent result.
+When you have a consistent answer, you are ready to use that number in
+the source code.  For a Sun Sparcstation 1000 running Solaris 2.3, the
+magical number is about .00053.  If you have a choice, you are better
+off with a smaller constant, and your results will "less often" show
+up as negative in profile statistics.
+
+The following shows how the trace_dispatch() method in the Profile
+class should be modified to install the calibration constant on a Sun
+Sparcstation 1000:
+
+	def trace_dispatch(self, frame, event, arg):
+		t = self.timer()
+		t = t[0] + t[1] - self.t - .00053 # Calibration constant
+
+		if self.dispatch[event](frame,t):
+			t = self.timer()
+			self.t = t[0] + t[1]
+		else:
+			r = self.timer()
+			self.t = r[0] + r[1] - t # put back unrecorded delta
+		return
+
+Note that if there is no calibration constant, then the line
+containing the callibration constant should simply say:
+
+		t = t[0] + t[1] - self.t  # no calibration constant
+
+You can also achieve the same results using a derived class (and the
+profiler will actually run equally fast!!), but the above method is
+the simplest to use.  I could have made the profiler "self
+calibrating", but it would have made the initialization of the
+profiler class slower, and would have required some *very* fancy
+coding, or else the use of a variable where the constant .00053 was
+placed in the code shown.  This is a ****VERY**** critical performance
+section, and there is no reason to use a variable lookup at this
+point, when a constant can be used.
+
+
+EXTENSIONS: Deriving Better Profilers
+
+The Profile class of profile was written so that derived classes
+could be developed to extend the profiler.  Rather than describing all
+the details of such an effort, I'll just present the following two
+examples of derived classes that can be used to do profiling.  If the
+reader is an avid Python programmer, then it should be possible to use
+these as a model and create similar (and perchance better) profile
+classes. 
+
+If all you want to do is change how the timer is called, or which
+timer function is used, then the basic class has an option for that in
+the constructor for the class.  Consider passing the name of a
+function to call into the constructor:
+
+	pr = profile.Profile(your_time_func)
+
+The resulting profiler will call your time function instead of
+os.times().  The function should return either a single number, or a
+list of numbers (like what os.times() returns).  If the function
+returns a single time number, or the list of returned numbers has
+length 2, then you will get an especially fast version of the dispatch
+routine.  
+
+Be warned that you *should* calibrate the profiler class for the
+timer function that you choose.  For most machines, a timer that
+returns a lone integer value will provide the best results in terms of
+low overhead during profiling.  (os.times is *pretty* bad, 'cause it
+returns a tuple of floating point values, so all arithmetic is
+floating point in the profiler!).  If you want to be substitute a
+better timer in the cleanest fashion, you should derive a class, and
+simply put in the replacement dispatch method that better handles your timer
+call, along with the appropriate calibration constant :-).

+	# The following calculates the overhead for using a profiler.  The
+	# problem is that it takes a fair amount of time for the profiler
+	# to stop the stopwatch (from the time it recieves an event).
+	# Similarly, there is a delay from the time that the profiler
+	# re-starts the stopwatch before the user's code really gets to
+	# continue.  The following code tries to measure the difference on
+	# a per-event basis. The result can the be placed in the
+	# Profile.dispatch_event() routine for the given platform.  Note
+	# that this difference is only significant if there are a lot of
+	# events, and relatively little user code per event.  For example,
+	# code with small functions will typically benefit from having the
+	# profiler calibrated for the current platform.  This *could* be
+	# done on the fly during init() time, but it is not worth the
+	# effort.  Also note that if too large a value specified, then
+	# execution time on some functions will actually appear as a
+	# negative number.  It is *normal* for some functions (with very
+	# low call counts) to have such negative stats, even if the
+	# calibration figure is "correct." 
+	#
+	# One alternative to profile-time calibration adjustments (i.e.,
+	# adding in the magic little delta during each event) is to track
+	# more carefully the number of events (and cumulatively, the number
+	# of events during sub functions) that are seen.  If this were
+	# done, then the arithmetic could be done after the fact (i.e., at
+	# display time).  Currintly, we track only call/return events.
+	# These values can be deduced by examining the callees and callers
+	# vectors for each functions.  Hence we *can* almost correct the
+	# internal time figure at print time (note that we currently don't
+	# track exception event processing counts).  Unfortunately, there
+	# is currently no similar information for cumulative sub-function
+	# time.  It would not be hard to "get all this info" at profiler
+	# time.  Specifically, we would have to extend the tuples to keep
+	# counts of this in each frame, and then extend the defs of timing
+	# tuples to include the significant two figures. I'm a bit fearful
+	# that this additional feature will slow the heavily optimized
+	# event/time ratio (i.e., the profiler would run slower, fur a very
+	# low "value added" feature.)

-/* What happens here is not trivial.
-   The BSD_TIME code needs <sys/time.h> (for struct timeval).
-   The rest of the code needs only time_t, except some MS-DOS
-   code which needs clock_t as well.
-   Standard C says that time_t is defined in <time.h>, and
-   does not have <sys/types.h>; THINK C agrees (MS-DOS too?).
-   What's worse, in pure 4.3 BSD, older SunOS versions, and
-   probably everything derived from BSD, you can't #include
-   both <time.h> and <sys/time.h> in the same file, since
-   <sys/time.h> includes <time.h> without any protection,
-   and <time.h> contains a typedef, which can't be parsed twice!
-   So on traditional UNIX systems we include <sys/types.h>
-   and <sys/time.h> and hope this implies <time.h> and time_t,
-   while on other systems, including conforming Standard C
-   systems (where 'unix' can't be defined), we rely on <time.h>.
-   Still one problem: BSD_TIME won't work with strict Standard C...
