* [3.10] bpo-44446: support lineno being None in traceback.FrameSummary ↵Pablo Galindo2021-07-081-0/+4
| | | | | | | | | | | | | (GH-26781) (GH-27072) As of 088a15c49d99ecb4c3bef93f8f40dd513c6cae3b, lineno is None instead of -1 if there is no line number. Signed-off-by: Filipe Laíns <lains@riseup.net>.

* bpo-40612: Fix SyntaxError edge cases in traceback formatting (GH-20072)Guido van Rossum2020-05-151-8/+26
| | | | | | | | | | | | | 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

* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-5/+5
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135

* bpo-34588: Fix an off-by-one error in traceback formatting. (GH-9077)Benjamin Peterson2018-09-101-2/+59
| | | | | | | | 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.

| * Issue #27348: Restore “Exception: None” formatting in traceback moduleMartin Panter2016-09-221-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

CALL_FUNCTION_VAR and CALL_FUNCTION_VAR_KW opcodes have been removed. 2 tests of test_traceback are currently broken: skip test, the issue #28050 was created to track the issue. Patch by Demur Rumed, design by Serhiy Storchaka, reviewed by Serhiy Storchaka and Victor Stinner.

| | | | | | | | | 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.

|\ | | | | | | | | | | | | | | | | | | | | | | | | Python finalization. Before the module kept a reference to the builtins module, but the module attributes are cleared during Python finalization. Instead, keep directly a reference to the open() function. This enhancement is not perfect, calling tokenize.open() can still fail if called very late during Python finalization. Usually, the function is called by the linecache module which is called to display a traceback or emit a warning.
