#3954: Fix error handling code in _hotshot.logreader
Will port to 2.6. hotshot was deleted from python 3.
........
This is the first batch of fixes that should be easy to verify based on context.
This fixes problem numbers: 220 (ast), 323-324 (symtable),
321-322 (structseq), 215 (array), 210 (hotshot), 182 (codecs), 209 (etree).
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.
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.
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.
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.
[ 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.
- 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.
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.
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.
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.
