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!
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.
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.
Turns out the mysterious "expected output" file contained exactly N dots,
because test_poll() has a loop that *usually* went around N times,
printing one dot on each loop trip. But there's no guarantee of that,
because the exact value of N depended on the vagaries of scheduling
time.sleep()s across two different processes. So stopped printing dots,
and got rid of the expected output file. Add a loop counter instead,
and verify that the loop goes around at least a couple of times. Also
cut the minimum time needed for this test from 4 seconds to 1.
mapping tests as possible in mapping_test.py and reuse the tests in
test_dict.py, test_userdict.py, test_weakref.py, test_os.py and test_shelve.py.
From SF patch #736962.
test_tuple.py and test_list.py. Common tests for tuple, list and UserList
are shared (in seq_tests.py and list_tests.py). Port tests to PyUnit.

unicode filenames"
Reorganize tests into functions so more combinations of
unicode/encoded/ascii can be tested, and while I was at it, upgrade to
unittest based test.

* Convert three test modules to unittest format.
* Expanded coverage in test_structseq.py.
* Raymond added a new test in test_sets.py
* It ran fine under "python regrtest.py test_warnings" but failed under
"python regrtest.py" presumably because other tests would add to
filtered warnings and not reset them at the end of the test.
* Converted to a unittest format for better control. Renamed
monkey() and unmonkey() to setUp() and tearDown().
* Increased coverage by testing all warnings in __builtin__.
* Increased coverage by testing regex matching of specific messages.
reported consistently with the *nix world. 'Lib/test/test_warnings.py'
came out as 'lib\test\test_warnings.py'. The basename is all we care
about so I used that.
Add API function simplefilter() that does not create or install
regular expressions to match message or module. Extend the filters
data structure to store None as an alternative to re.compile("").
Move the _test() function to test_warnings and add some code to try
and avoid disturbing the global state of the warnings module.
The compiler was reseting the list comprehension tmpname counter for each function, but the symtable was using the same counter for the entire module. Repair by move tmpname into the symtable entry.
Bugfix candidate.
getpwnam()/getpwuid() return consistent data.
Change test_grp to check that getgrall() and
getgrnam()/getgrgid() return consistent data.
Add error checks similar to test_pwd.py.
Port test___all__.py to PyUnit.
From SF patch #662807.
between str, unicode, UserString and the string module
as possible. This increases code coverage in stringobject.c
from 83% to 86% and should help keep the string classes
in sync in the future. From SF patch #662807
extension implemented flush() was fixed. Scott also rewrite the
zlib test suite using the unittest module. (SF bug #640230 and
patch #678531.)
Backport candidate I think.
port the tests to PyUnit and add many tests for error
cases. This increases code coverage in Python/bltinmodule.c
from 75% to 92%. (From SF patch #662807, with
assert_(not fcmp(x, y)) replaced with assertAlmostEqual(x, y)
where possible)
sys.getwindowsversion() on Windows (new enahanced Tim-proof <wink>
version), and fix test_pep277.py in a few minor ways.
Including doc and NEWS entries.
the tokenize module by test_tokenize.py. The FutureWarnings only
appeared during installation, and I've figured out a way to suppress
those in a different way.
existed at the time atexit first got imported. That's a bug, and this
fixes it.
Also reworked test_atexit.py to test for this too, and to stop using
an "expected output" file, and to test what actually happens at exit
instead of just simulating what it thinks atexit will do at exit.
Bugfix candidate, but it's messy so I'll backport to 2.2 myself.
If multiple header fields with the same name occur, they are combined
according to the rules in RFC 2616 sec 4.2:
Appending each subsequent field-value to the first, each separated by
a comma. The order in which header fields with the same field-name are
received is significant to the interpretation of the combined field
value.
Also add a test that Python doesn't die with SIGXFSZ if it exceeds the
file rlimit. (Assuming this will also test the behavior when the 2GB
limit is exceed on a platform that doesn't have large file support.)
PEP 285. Everything described in the PEP is here, and there is even
some documentation. I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison. I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.
Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.
457466: popenx() argument mangling hangs python
226766: popen('python -c"...."') tends to hang
Fixes argument quoting in w9xpopen.exe for Windows 9x. w9xpopen.exe
also never attempts to display a MessageBox when not executed
interactively.
Added test_popen() test. This test currently just executes
"python -c ..." as a child process, and checks that the expected
arguments were all recieved correctly by the child process. This
test succeeds for me on Win9x, win2k and Linux, and I hope it does
for other popen supported platforms too :)
There were never tests for the fact that list() always returns a *new*
list object, even when the argument is a list, while tuple() may
return a reference to the argument when it is a tuple. Now there are.
Fix for the UTF-8 decoder: it will now accept isolated surrogates
(previously it raised an exception which causes round-trips to
fail).
Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for
marshalling Unicode objects, so we better make sure it works for
all Unicode code points, including isolated surrogates).
Bumped the PYC magic in a non-standard way -- please review. This
was needed because the old PYC format used illegal UTF-8 sequences
for isolated high surrogates which now raise an exception.
type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
