* time.clock() now emits a DeprecationWarning (GH-4020)Victor Stinner2017-10-171-1/+1
| | | | | | | | | | bpo-31803: time.clock() and time.get_clock_info('clock') now emit a DeprecationWarning warning. Replace time.clock() with time.perf_counter() in tests and demos. Remove also hasattr(time, 'monotonic') in test_time since time.monotonic() is now always available since Python 3.5.

* Issue #14428: Use the new time.perf_counter() and time.process_time() functionsVictor Stinner2012-04-291-34/+2
| | | | | | | | | | | | * Replace "time.clock on windows, or time.time" with time.perf_counter() * profile module: only use time.process_time() instead of trying different functions providing the process time * timeit module: use time.perf_counter() by default, time.time() and time.clock() can still be used using --time and --clock options * pybench program: use time.perf_counter() by default, add support for the new time.process_time() and time.perf_counter() functions, but stay backward compatible. Use also time.get_clock_info() to display information of the timer.

| | | | | | | | | | and .keys(), .items(), .values() return dict views. The dict views aren't fully functional yet; in particular, they can't be compared to sets yet. but they are useful as "iterator wells". There are still 27 failing unit tests; I expect that many of these have fairly trivial fixes, but there are so many, I could use help.
* Fix most trivially-findable print statements.Guido van Rossum2007-02-091-8/+8
| | | | | | | | | There's one major and one minor category still unfixed: doctests are the major category (and I hope to be able to augment the refactoring tool to refactor bona fide doctests soon); other code generating print statements in strings is the minor category. (Oh, and I don't know if the compiler package works.)

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>).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
