* bpo-40612: Fix SyntaxError edge cases in traceback formatting (GH-20072)Guido van Rossum2020-05-151-11/+18
| | | | | | | | | | | | | This fixes both the traceback.py module and the C code for formatting syntax errors (in Python/pythonrun.c). They now both consistently do the following: - Suppress caret if it points left of text - Allow caret pointing just past end of line - If caret points past end of line, clip to *just* past end of line The syntax error formatting code in traceback.py was mostly rewritten; small, subtle changes were applied to the C code in pythonrun.c. There's still a difference when the text contains embedded newlines. Neither handles these very well, and I don't think the case occurs in practice. Automerge-Triggered-By: @gvanrossum
* Fix typo in Lib/tracepack.py (GH-19605)Galden2020-04-201-1/+1

* bpo-26502: Implement FrameSummary.__len__() (GH-8632)Berker Peksag2018-09-101-0/+3

* bpo-34588: Fix an off-by-one error in traceback formatting. (GH-9077)Benjamin Peterson2018-09-101-10/+19
| | | | | | | | The recursive frame pruning code always undercounted the number of elided frames by one. That is, in the "[Previous line repeated N more times]" message, N would always be one too few. Near the recursive pruning cutoff, one frame could be silently dropped. That situation is demonstrated in the OP of the bug report. The fix is to start the identical frame counter at 1.
* bpo-27910: Update documentation of traceback module (GH-6116)torsava2018-08-021-13/+16
| | | | | | | | | | In the documentation for the traceback module, the definitions of functions extract_tb(), format_list() and classmethod StackSummary.from_list() mention the old style 4-tuples that these functions used to return or accept. Since Python 3.5, however, they return or accept a FrameSummary object instead of a 4-tuple, or a StackSummary object instead of a list of 4-tuples.

| * Issue #27348: Restore “Exception: None” formatting in traceback moduleMartin Panter2016-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression caused by revision 73afda5a4e4c. Also reverts the decimal test workaround added in revision 5f3dd0a2b1ab. Remove test_without_exception(). According to revision ecaafc32c500, this was added in Python 2 so that print_exc() would output “None” when called with no exception set. However print_exc() never worked like this in Python 3, and the use case is not documented. Restore TracebackCases class name (instead of SyntaxTracebackCases), because the class also tests other exceptions.

* | Issue #26823: Abbreviate recursive tracebacksNick Coghlan2016-08-151-0/+23
| | | | | | | | | | | | | | | | Large sections of repeated lines in tracebacks are now abbreviated as "[Previous line repeated {count} more times]" by both the traceback module and the builtin traceback rendering. Patch by Emanuel Barry.

* Remaining fallout from 17911Robert Collins2015-03-051-2/+8
| | | | | | | | | | | | | The code module was using a private function from traceback in order to skip a frame - used the direct interface to do that instead, The decimal module suffered minor fallout from formatting changes ('None' as a value is now not printed by traceback, the same as None was not before). The cgitb module was passing a bogus exception type (type.__name__) into format_exception, which uncovered that format_exception and print_exception had been ignoring the etype for some time, so the compatibility thunk to the new code now does the same thing.
* Issue #17911: traceback module overhaulRobert Collins2015-03-041-133/+351
| | | | | | | | | Provide a way to seed the linecache for a PEP-302 module without actually loading the code. Provide a new object API for traceback, including the ability to not lookup lines at all until the traceback is actually rendered, without any trace of the original objects being kept alive.
