| | | | | | | | * bpo-35454: Fix miscellaneous minor issues in error handling. * Fix a null pointer dereference. (cherry picked from commit 8905fcc85a6fc3ac394bc89b0bbf40897e9497a6) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* bpo-35441: Remove dead and buggy code related to PyList_SetItem(). (GH-11033)Miss Islington (bot)2018-12-081-2/+2
| | | | | | | | | | | | In _localemodule.c and selectmodule.c, remove dead code that would cause double decrefs if run. In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases where a new list is populated and there is no possibility of an error. In addition, check if the list changed size in the loop in array_array_fromlist().

| | | | | | | This kludge is from 1992. Any C99 compiler is going to be able to handle the ceval dispatch switch. Anyway, we have much bigger switches than the ceval dispatch one around. (See, e.g., Objects/unicodetype_db.h.)

* bpo-28411: Support other mappings in PyInterpreterState.modules. (#3593)Eric Snow2017-09-151-2/+1
| | | | | The concrete PyDict_* API is used to interact with PyInterpreterState.modules in a number of places. This isn't compatible with all dict subclasses, nor with other Mapping implementations. This patch switches the concrete API usage to the corresponding abstract API calls. We also add a PyImport_GetModule() function (and some other helpers) to reduce a bunch of code duplication.

* bpo-30039: Don't run signal handlers while resuming a yield from stack (#1081)Nathaniel J. Smith2017-05-171-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we have a chain of generators/coroutines that are 'yield from'ing each other, then resuming the stack works like: - call send() on the outermost generator - this enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - which calls send() on the next generator - which enters _PyEval_EvalFrameDefault, which re-executes the YIELD_FROM opcode - ...etc. However, every time we enter _PyEval_EvalFrameDefault, the first thing we do is to check for pending signals, and if there are any then we run the signal handler. And if it raises an exception, then we immediately propagate that exception *instead* of starting to execute bytecode. This means that e.g. a SIGINT at the wrong moment can "break the chain" – it can be raised in the middle of our yield from chain, with the bottom part of the stack abandoned for the garbage collector. The fix is pretty simple: there's already a special case in _PyEval_EvalFrameEx where it skips running signal handlers if the next opcode is SETUP_FINALLY. (I don't see how this accomplishes anything useful, but that's another story.) If we extend this check to also skip running signal handlers when the next opcode is YIELD_FROM, then that closes the hole – now the exception can only be raised at the innermost stack frame. This shouldn't have any performance implications, because the opcode check happens inside the "slow path" after we've already determined that there's a pending signal or something similar for us to process; the vast majority of the time this isn't true and the new check doesn't run at all.

| | | | | | | | | | When LOAD_METHOD is used for calling C mehtod, PyMethodDescrObject was passed to profilefunc from 5566bbb. But lsprof traces only PyCFunctionObject. Additionally, there can be some third party extension which assumes passed arg is PyCFunctionObject without calling PyCFunction_Check(). So make PyCFunctionObject from PyMethodDescrObject when tstate->c_profilefunc is set.
