* [2.7] bpo-35441: Remove dead and buggy code related to PyList_SetItem(). ↵Serhiy Storchaka2018-12-192-3/+3
| | | | | | | | | | | | | | (GH-11033) (GH-11234) 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(). (cherry picked from commit 99d56b53560b3867844472ae381fb3f858760621) Co-authored-by: Zackery Spytz <zspytz@gmail.com>
* ceval.c: mark debug 'filename' variable as unused (GH-11074)Victor Stinner2018-12-101-3/+7
| | | | Use GCC __attribute__((unused)) to mark the debug variable 'filename' as unused in Python/ceval.c.
* bpo-33015: Use malloc() in PyThread_start_new_thread() (GH-10829)Victor Stinner2018-11-301-3/+3
| | | | | The pthread implementation of PyThread_start_new_thread() now uses malloc/free rather than PyMem_Malloc/PyMem_Free, since the latters are not thread-safe.
* bpo-33015: Fix UB in pthread PyThread_start_new_thread (GH-6008) (GH-10823)Victor Stinner2018-11-301-4/+36
| | | | | | | | | Fix an undefined behaviour in the pthread implementation of PyThread_start_new_thread(): add a function wrapper to always return NULL. Add pythread_callback struct and pythread_wrapper() to thread_pthread.h. (cherry picked from commit 9eea6eaf23067880f4af3a130e3f67c9812e2f30)
* Add a missed PyErr_NoMemory() in symtable_new(). (GH-10576)Miss Islington (bot)2018-11-161-1/+3
| | | | | | | This missed PyErr_NoMemory() could cause a SystemError when calling _symtable.symtable(). (cherry picked from commit ad65f15581173542f1d2a9968a63bee272510ce3) Co-authored-by: Zackery Spytz <zspytz@gmail.com>

| | | | | | | | | | | | lines. (GH-10284) (GH-10335) (GH-10336) Two kind of mistakes: 1. Missed space. After concatenating there is no space between words. 2. Missed comma. Causes unintentional concatenating in a list of strings. (cherry picked from commit 34fd4c20198dea6ab2fe8dc6d32d744d9bde868d) (cherry picked from commit 7054e5c80b6e98cd44e22d1bc2d7f0a94343089d)

| | | | | | | | | Fix the following warning: Python/pystrtod.c: In function 'format_float_short': Python/pystrtod.c:1007:13: warning: 'strncpy' output truncated before terminating nul copying 3 bytes from a string of the same length [-Wstringop-truncation] strncpy(p, "ERR", 3); (cherry picked from commit 9fb84157595a385f15799e5d0729c1e1b0ba9d38)
* bpo-25083: Python can sometimes create incorrect .pyc files (GH-8449)tzickel2018-09-101-0/+3
| | | | | | Python 2 never checked for I/O error when reading .py files and thus could mistake an I/O error for EOF and create incorrect .pyc files. This adds an check for this and aborts on an error.

| | | | | | | | | | | | | | | | | GCC says: ../cpython/Python/marshal.c: In function ‘PyMarshal_WriteLongToFile’: ../cpython/Python/marshal.c:70:35: warning: ‘wf.ptr’ may be used uninitialized in this function [-Wmaybe-uninitialized] else if ((p)->ptr != (p)->end) *(p)->ptr++ = (c); \ ^~ ../cpython/Python/marshal.c:70:47: warning: ‘wf.end’ may be used uninitialized in this function [-Wmaybe-uninitialized] else if ((p)->ptr != (p)->end) *(p)->ptr++ = (c); \ ^~ ../cpython/Python/marshal.c:77:10: warning: ‘wf.str’ may be used uninitialized in this function [-Wmaybe-uninitialized] if (p->str == NULL) ~^~~~~ This isn't a real problem because if the file pointer is not NULL, the string-related fields are never touched. But, it doesn't hurt to set the unused fields to NULL.

Moreover, allocations statistics are now dumped into stderr rather than stdout. * Add @test.support.requires_type_collecting decorator: skip test if COUNT_ALLOCS is defined * Fix tests for COUNT_ALLOCS: decorate some methods with @requires_type_collecting * test_sys.test_objecttypes(): update object type when COUNT_ALLOCS is defined
