Martin v. Löwis 6685128b97 Fix more ssize_t issues. 2006-04-22 11:40:03 +00:00
Martin v. Löwis f24de1e990 Patch #1470300: Port _hotshot to QNX4.25 port. 2006-04-14 15:07:46 +00:00
Anthony Baxter 7cbc0f5524 C++ compiler changes. casts, rename variables with reserved names. 2006-04-13 07:19:01 +00:00
Tim Peters df44ab7b1c _hotshot hotshot_profiler(): If write_header() returned
an error code, this let `self` leak.  This is a disaster
on Windows, since `self` already points to a newly-opened
file object, and it was impossible for Python code to
close the thing since the only reference to it was in a
blob of leaked C memory.

test_hotshot test_bad_sys_path():  This new test provoked
the C bug above.  This test passed, but left an open
"@test" file behind, which caused a massive cascade of
bogus test failures in later, unrelated tests on Windows.
Changed the test code to remove the @test file it leaves
behind, which relies on the change above to close that
file first.

Neal Norwitz 60da31660c Thanks to Coverity, these were all reported by their Prevent tool.
All of these (except _lsprof.c) should be backported.  Particularly
the hotshot change which validates sys.path.  Can someone backport?

Armin Rigo de5f05f3b1 Nobody on python-dev seemed particularly bothered that Hotshot generates half-
meaningless numbers, but I figured out I would fix that bug anyway.

Jeremy Hylton ec97a28b60 Fix a bunch of imports to use code.h instead of compile.h.

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
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.

Armin Rigo a41276956d SF bug #808756: refleaks in _hotshot.c. 2004-08-03 08:33:55 +00:00
Neal Norwitz 7a135166f6 SF patch #969180, hotshot incorrectly computes elapsed time by Jason
Beardsley.

If the seconds are different, we still need to calculate the differences
between milliseconds.

Also, on a Gentoo Linux (2.6.5) dual Athlon MP box with glibc 2.3,
time can go backwards.  This probably happens when the process switches
the CPU it's running on.  Time can also go backwards when running NTP.
If we detect a negative time delta (ie, time went backwards), return
a delta of 0.  This prevents an illegal array access elsewhere.
I think it's safest to *not* update prev_timeofday in this case, so we
return without updating.

Backport candidate.

Jack Jansen eddc1449ba Getting rid of all the code inside #ifdef macintosh too. 2003-11-20 01:44:59 +00:00
Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter
to more accurately describe what the function does.

Suggested by Thomas Wouters.
2003-03-17 19:46:11 +00:00
Raymond Hettinger e0cce8f8f0 Created PyObject_GenericGetIter().
Factors out the common case of returning self.

Jason Tishler fb8595df4f Patch #661760: Cygwin auto-import module patch
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Michael W. Hudson 806d1c817a Fix *really* embarrassing typo reported by Raymond Hettinger. 2002-09-11 17:09:45 +00:00
Michael W. Hudson 02ff6a9952 A slight change to SET_LINENO-less tracing.
This makes things a touch more like 2.2.  Read the comments in
Python/ceval.c for more details.

Michael W. Hudson dd32a91cc0 This is my patch
[ 587993 ] SET_LINENO killer

Remove SET_LINENO.  Tracing is now supported by inspecting co_lnotab.

Many sundry changes to document and adapt to this change.

Jason Tishler 4df78cddaa Patch #588561: Cygwin _hotshot patch
YA Cygwin module patch very similar to other patches
that I have submitted.  I tested under Cygwin and Red
Hat Linux 7.1.

Guido van Rossum 0b624f69b5 unpack_string(): avoid a compiler warning (about a real bug!) by
copying the result of fgetc() into an int variable before testing it
for EOF.

Fred Drake 666bf52a16 - When the log reader detects end-of-file, close the file.
- The log reader now provides a "closed" attribute similar to the
  profiler.
- Both the profiler and log reader now provide a fileno() method.
- Use METH_NOARGS where possible, allowing simpler code in the method
  implementations.
2002-07-18 19:11:44 +00:00
Fred Drake 5c3ed3db9a Mark the closed attribute of the profiler with PyDoc_STR(), and added
a docstring for the info attribute of the logreader object.
2002-07-17 19:38:05 +00:00
Fred Drake d1eb8b61d0 Added a docstring for the closed attribute.
write_header():  When we encounter a non-string object in sys.path, record
    a fairly mindless placeholder rather than dying.  Possibly could record
    the repr of the object found, but not clear whether that matters.
2002-07-17 18:54:20 +00:00
Guido van Rossum 9cb64b954a Some modernization. Get rid of the redundant next() method. Always
assume tp_iter and later fields exist.  Use PyObject_GenericGetAttr
instead of providing our own tp_getattr hook.

Neil Schemenauer 8b6b491ed7 The logreader object did not always refill the input buffer correctly
and got confused by certain log files.  Remove logreader_refill and the
associated logic and replace with fgetc.

Fred Drake 2c146bfa28 start() and stop() methods: return None where there is no exception;
returning NULL causes the interpreter to raise a SystemError.
Noted by Anthony Baxter at Python 10.

Martin v. Löwis cdc4451222 Include <unistd.h> in Python.h. Fixes #500924. 2002-01-12 11:05:12 +00:00
Fred Drake 62c1e3c1b9 Make sure to propogate errors that arise when profiling data cannot be
written to the log file, and turn off the profiler.
This closes SF bug #483925.

Tim Peters 885d457709 sprintf -> PyOS_snprintf in some "obviously safe" cases.
Also changed <>-style #includes to ""-style in some places where the
former didn't make sense.

Fred Drake f12a68ccd0 Fix memory leak. This is (very!) similar to part of SF patch #478006. 2001-11-09 15:59:36 +00:00
Fred Drake 4c2e1af890 Make the low-level log-reader object export a dictionary mapping keys
to lists of values, giving the contents of all the ADD_INFO records
seen so far.  This is initialized agressively when the log file is
opened, so that whoever is looking at the log reader can always see
the initial data loaded into the data stream.  ADD_INFO events later
in the log file continue to be reported to the application layer as
before.

Add a new method, addinfo(), to the profiler.  This can be used to
insert additional ADD_INFO records into the profiler log.

Fix the tp_flags and tp_name slots on the type objects.

Jack Jansen 963659af29 Got this to work in MacPython. The code is #ifdef macintosh style (to match the existing #ifdef MS_WINDOWS), but eventually ifdeffing on configure features is probably better. 2001-10-23 22:26:16 +00:00
Fred Drake 30d1c75d15 Removed useless code to count the number of calls into the profiler.
Added support for saving the names of the functions observed into the
profile log.
Added support for using the profiler to measure coverage without collecting
timing information (which is the slow part).  Coverage logs can also be
substantially smaller than profiling logs where per-line information is
being collected.
Updated comments on the log format; corrected record type values in some
of the record descriptions.

Tim Peters feab23f834 My editor can't deal with long backslash-continued strings. Changed 'em.
This still doesn't compile on Windows, but at least I have a shot at
fixing that now.
2001-10-13 00:11:10 +00:00
Tim Peters 1566a17af5 Get hotshot closer to compiling on Windows.
Still broken:  GETTIMEOFDAY.  This macro obviously isn't being defined
on Windows, so there's logic errors here I'd rather Fred untangled.
