* gh-93883: elide traceback indicators when possible (#93994)John Belmonte2022-07-111-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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).

* gh-92228: disable the compiler's 'small exit block inlining' optimization ↵Irit Katriel2022-07-071-0/+14
| | | | | | | for blocks that have a line number (GH-94592) Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature. This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None".

| | | | | | | (GH-94255) Seems in the past the copy of builtins was not made in some scenarios, and the error was silenced. Write it now to stderr, so we have a chance to see it.

| | | | | | pthread _PyThread_cond_after() implementation now uses the _PyTime_t type to handle properly overflow: clamp to the maximum value. Remove MICROSECONDS_TO_TIMESPEC() function.

* gh-93937: PyOS_StdioReadline() uses PyConfig.legacy_windows_stdio (#94024)Victor Stinner2022-06-201-0/+3
| | | | | | | On Windows, PyOS_StdioReadline() now gets PyConfig.legacy_windows_stdio from _PyOS_ReadlineTState, rather than using the deprecated global Py_LegacyWindowsStdioFlag variable. Fix also a compiler warning in Py_SetStandardStreamEncoding().
* GH-93516: Speedup line number checks when tracing. (GH-93763)Mark Shannon2022-06-201-7/+9

| | | | | | | | Reformat the pthread implementation of PyThread_acquire_lock_timed() using a mutex and a conditioinal variable. * Add goto to avoid multiple indentation levels and exit quickly * Use "while(1)" and make the control flow more obvious. * PEP 7: Add braces around if blocks.
