It computes a constant about 60% higher on my Win98SE box than the old method, and the new constant appears much more realistic. Deleted the undocumented simple(), instrumented(), and profiler_simulation() methods (which existed only to support the previous calibration method).

* Guido points out that the comments for self.cur[2] were subtly butTim Peters2001-10-071-17/+29
| | | | | | | | seriously wrong. This started out by just fixing the docs, but then it occurred to me that the doc confusion propagated into misleading vrbl names too, so I also renamed those to match reality. As a result, INO the time computations are much easier to understand now (within the limitations of vast quantities of 3-character names <wink>).

* Hopefully fix the profiler right. Add a test suite that checks thatGuido van Rossum2001-10-041-18/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | it deals correctly with some anomalous cases; according to this test suite I've fixed it right. The anomalous cases had to do with 'exception' events: these aren't generated when they would be most helpful, and the profiler has to work hard to recover the right information. The problems occur when C code (such as hasattr(), which is used as the example here) calls back into Python code and clears an exception raised by that Python code. Consider this example: def foo(): hasattr(obj, "bar") Where obj is an instance from a class like this: class C: def __getattr__(self, name): raise AttributeError The profiler sees the following sequence of events: call (foo) call (__getattr__) exception (in __getattr__) return (from foo) Previously, the profiler would assume the return event returned from __getattr__. An if statement checking for this condition and raising an exception was commented out... This version does the right thing.

* Change the sense of a test in how the profiler interprets exception events.Fred Drake2001-09-271-1/+1
| | | | | This should fix a bug in how time is allocated during exception propogation (esp. in the presence of finally clauses).

* Performance improvements to the profiler:Fred Drake2001-06-081-57/+93
| | | | | | | | | | | | | | | | | Ensure that all the default timers are called as functions, not an expensive method wrapper around a variety of different functions. Agressively avoid dictionary lookups. Modify the dispatch scheme (Profile.trace_dispatch_*(), where * is not 'call', 'exception' or 'return') so that the callables dispatched to are simple functions and not bound methods -- this reduces the number of layers of Python call machinery that gets touched. Remove a couple of duplicate imports from the "if __name__ == ..." section. This closes SF patch #430948.
* Add doc string for run from profile.doc. (pydoc motivates me to writeJeremy Hylton2001-03-141-5/+13
| | | | | | | | | | good doc strings.) Fix silly argument handling; was using *args but really wanted 1 optional arg. XXX Should profile.doc be merged into the documentation and removed from the Lib directory?

| | | | | | | | | | comments, docstrings or error messages. I fixed two minor things in test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't"). There is a minor style issue involved: Guido seems to have preferred English grammar (behaviour, honour) in a couple places. This patch changes that to American, which is the more prominent style in the source. I prefer English myself, so if English is preferred, I'd be happy to supply a patch myself ;)
* More trivial comment -> docstring transformations by Ka-Ping Yee,Guido van Rossum2000-02-041-58/+52
| | | | | | | | | | | | | | | | | | who writes: Here is batch 2, as a big collection of CVS context diffs. Along with moving comments into docstrings, i've added a couple of missing docstrings and attempted to make sure more module docstrings begin with a one-line summary. I did not add docstrings to the methods in profile.py for fear of upsetting any careful optimizations there, though i did move class documentation into class docstrings. The convention i'm using is to leave credits/version/copyright type of stuff in # comments, and move the rest of the descriptive stuff about module usage into module docstrings. Hope this is okay.
