* gh-93883: elide traceback indicators when possible (#93994)John Belmonte2022-07-111-13/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * gh-93883: elide traceback indicators when possible Elide traceback column indicators when the entire line of the frame is implicated. This reduces traceback length and draws even more attention to the remaining (very relevant) indicators. Example: ``` Traceback (most recent call last): File "query.py", line 99, in <module> bar() File "query.py", line 66, in bar foo() File "query.py", line 37, in foo magic_arithmetic('foo') File "query.py", line 18, in magic_arithmetic return add_counts(x) / 25 ^^^^^^^^^^^^^ File "query.py", line 24, in add_counts return 25 + query_user(user1) + query_user(user2) ^^^^^^^^^^^^^^^^^ File "query.py", line 32, in query_user return 1 + query_count(db, response['a']['b']['c']['user'], retry=True) ~~~~~~~~~~~~~~~~~~^^^^^ TypeError: 'NoneType' object is not subscriptable ``` Rather than going out of our way to provide indicator coverage in every traceback test suite, the indicator test suite should be responible for sufficient coverage (e.g. by adding a basic exception group test to ensure that margin strings are covered).

* bpo-43950: support some multi-line expressions for PEP 657 (GH-27339)Batuhan Taskaya2021-07-251-8/+10
| | | | | | | | | | | | | | | | | | | | | This is basically something that I noticed up while fixing test runs for another issue. It is really common to have multiline calls, and when they fail the display is kind of weird since we omit the annotations. E.g; ``` $ ./python t.py Traceback (most recent call last): File "/home/isidentical/cpython/cpython/t.py", line 11, in <module> frame_1() ^^^^^^^^^ File "/home/isidentical/cpython/cpython/t.py", line 5, in frame_1 frame_2( File "/home/isidentical/cpython/cpython/t.py", line 2, in frame_2 return a / 0 / b / c ~~^~~ ZeroDivisionError: division by zero ``` This patch basically adds support for annotating the rest of the line, if the instruction covers multiple lines (start_line != end_line).

* 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
