Jeffrey Yasskin c8d30fec16 Fix issue #1689458 by teaching frame_setlineno how to jump to the first line of
a code object.

Jeffrey Yasskin 61328eef1f While I was modifying test_trace, it threw an exception when I accidentally
made it try to set the line number from the trace callback for a 'call' event.
This patch makes the error message a little more helpful in that case, and
makes it a little less likely that a future editor will make the same mistake
in test_trace.

Amaury Forgeot d'Arc 48ebc264f8 Disable gc when running test_trace, or we may record the __del__ of collected objects.
See http://mail.python.org/pipermail/python-checkins/2008-April/068633.html
the extra events perfectly match several calls to socket._fileobject.__del__()

Amaury Forgeot d'Arc 99af7dbc07 Change r60575 broke test_compile:
there is no need to emit co_lnotab item when both offsets are zeros.

Amaury Forgeot d'Arc 6fd03bb607 #1750076: Debugger did not step on every iteration of a while statement.
The mapping between bytecode offsets and source lines (lnotab) did not contain
an entry for the beginning of the loop.

Now it does, and the lnotab can be a bit larger:
in particular, several statements on the same line generate several entries.
However, this does not bother the settrace function, which will trigger only
one 'line' event.

The lnotab seems to be exactly the same as with python2.4.

Georg Brandl 56112895d6 #1648: add sys.gettrace() and sys.getprofile(). 2008-01-20 13:59:46 +00:00
Amaury Forgeot d'Arc 0d75f09177 Merge from py3k branch:
Correction for issue1265 (pdb bug with "with" statement).

When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set.  This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.

It is necessary to save/restore the exception around the call to the trace
function.

This happens a lot with py3k: isinstance() of an ABCMeta instance runs
    def __instancecheck__(cls, instance):
        """Override for isinstance(instance, cls)."""
        return any(cls.__subclasscheck__(c)
                   for c in {instance.__class__, type(instance)})
which lets an opened generator expression each time it returns True.

Backport candidate, even if the case is less frequent in 2.5.

Neal Norwitz 4ffedadb10 Bug #1191458: tracing over for loops now produces a line event
on each iteration.  I'm not positive this is the best way to handle
this.  I'm also not sure that there aren't other cases where
the lnotab is generated incorrectly.  It would be great if people
that use pdb or tracing could test heavily.

Also:
 * Remove dead/duplicated code that wasn't used/necessary
   because we already handled the docstring prior to entering the loop.
 * add some debugging code into the compiler (#if 0'd out).

Jeremy Hylton ed40ea1159 Generate line number table entries for except handlers.
Re-enable all the tests in test_trace.py except one.  Still not sure that these tests test what they used to test, but they pass.  One failing test seems to be caused by undocumented line number table behavior in Python 2.4.

Armin Rigo 706933821c The fix in ceval.c 2.386 allows iteration-by-iteration line tracing even in
single-line loops.

Walter Dörwald 21d3a32b99 Combine the functionality of test_support.run_unittest()
and test_support.run_classtests() into run_unittest()
and use it wherever possible.

Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.

From SF patch #662807.

Michael W. Hudson 58ee2af48e Armin Rigo's fix & test for
[ 729622 ] line tracing hook errors

with massaging from me to integrate test into test suite.

Michael W. Hudson cfd3884882 This is Richie Hindle's patch
[ 643835 ] Set Next Statement for Python debuggers

with a few tweaks by me: adding an unsigned or two, mentioning that
not all jumps are allowed in the doc for pdb, adding a NEWS item and
a note to whatsnew, and AuCTeX doing something cosmetic to libpdb.tex.

Michael W. Hudson 006c75265f This is Richie Hindle's patch:
[ 631276 ] Exceptions raised by line trace function

It conflicted with the patches from Armin I just checked it, so I had
to so some bits by hand.

Michael W. Hudson fb4d6ecd07 Fix for the recursion_level bug Armin Rigo reported in sf
patch #617312, both on the trunk and the 22-maint branch.

Also added a test case, and ported the test_trace I wrote for HEAD
to 2.2.2 (with all those horrible extra 'line' events ;-).
2002-10-02 13:13:45 +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.
2002-09-11 15:36:32 +00:00
Michael W. Hudson 519a342d79 Bunch more tests. 2002-09-11 14:47:51 +00:00
Michael W. Hudson 53d58bb369 Further SET_LINENO reomval fixes. See comments in patch #587933.
Use a slightly different strategy to determine when not to call the line
trace function.  This removes the need for the RETURN_NONE opcode, so
that's gone again.  Update docs and comments to match.

Thanks to Neal and Armin!

Also add a test suite.  This should have come with the original patch...
