Based on lsprof (patch #1212837) by Brett Rosen and Ted Czotter.
With further editing by Michael Hudson and myself.
History in svn repo: http://codespeak.net/svn/user/arigo/hack/misc/lsprof
* Module/_lsprof.c is the internal C module, Lib/cProfile.py a wrapper.
* pstats.py updated to display cProfile's caller/callee timings if available.
* setup.py and NEWS updated.
* documentation updates in the profiler section:
- explain the differences between the three profilers that we have now
- profile and cProfile can use a unified documentation, like (c)Pickle
- mention that hotshot is "for specialized usage" now
- removed references to the "old profiler" that no longer exists
* test updates:
- extended test_profile to cover delicate cases like recursion
- added tests for the caller/callee displays
- added test_cProfile, performing the same tests for cProfile
* TO-DO:
- cProfile gives a nicer name to built-in, particularly built-in methods,
which could be backported to profile.
- not tested on Windows recently!
Not sure why/how _handlers/_handlerList is out of sync. This could
indicate a deeper problem.
In test_logging, the only absolutely necessary change to get working
was tcpserver.abort = 1. But we don't want to wait infinitely
to join the threads, so give a 2.0 second timeout.
There doesn't appear to be a need for a local abort variable
in serve_until_stopped, so just use the instance member.
Note the problem is only on HEAD, not in 2.4.
on both Unix (SVR4 and BSD) and Windows. Restores behaviour of passing -1
for anonymous memory on Unix. Use MAP_ANONYMOUS instead of _ANON since
the latter is deprecated according to Linux (gentoo) man pages.
Should we continue to allow mmap.mmap(0, length) to work on Windows?
0 is a valid fd.
Will backport bugfix portions.
tty opened by os.openpty() isn't always a tty according to os.isatty(), when
it's tested inside the process that opened it. Doesn't affect actual
functionality, as using a tty this way is rarely, if ever, useful. Ignoring
the failure allows the test for actual functionality to continue.
Will backport to 2.4-maint.
Expand set of errors caught in set_context(). Some new errors, some
old error messages changed for consistency.
Fixed error checking in generator expression code. The first set of
tests were impossible condition given the grammar. In general, the
ast code uses REQ() for those sanity checks.
Fix some error handling for augmented assignments. As comments in the
code explain, set_context() ought to work here, but I got unexpected
crashes when I tried it. Should come back to this.
Add note to Grammar that yield expression is a special case.
Add doctest cases for SyntaxErrors raised by ast.c.
before the listener was ready (on gentoo x86 buildslave). This
caused the listener to not exit normally since nobody connected to it
(waited in accept()). The exception was raised in the other thread
and the test failed.
This fix doesn't completely eliminate the race, but should make it
near impossible to trigger. Hopefully it's good enough.
bugs which cause the interpreter to crash. I'm sure we can find a few
more. Many missing bugs deal with variations on unchecked infinite recursion
(like coerce.py).
cases if TERM isn't set or is unknown (perhaps we should only check if
unset or empty?)
Skip the test if TERM isn't set. This seems to occur when running under
buildbot and presumably cron.

Will backport if it works.
the tests. This stops the confusing/annoying:
No handlers could be found for logger "cookielib"
message we got whenever some test running after test_logging
happened to use cookielib.py (when not using regrtest's -r,
this happened during test_urllib2; when using -r, it varied).
