| | | | bpo-34679, bpo-38563: asyncio.ProactorEventLoop.close() now only calls signal.set_wakeup_fd() in the main thread.
* bpo-37415: Fix stdatomic.h header check for ICC compiler (GH-16717)Victor Stinner2019-10-221-0/+2
| | | | | | | | | | | | Fix stdatomic.h header check for ICC compiler: the ICC implementation lacks atomic_uintptr_t type which is needed by Python. Test: * atomic_int and atomic_uintptr_t types * atomic_load_explicit() and atomic_store_explicit() * memory_order_relaxed and memory_order_seq_cst constants But don't test ATOMIC_VAR_INIT(): it's not used in Python.

* bpo-38502: regrtest uses process groups if available (GH-16829)Victor Stinner2019-10-181-0/+3
| | | | | test.regrtest now uses process groups in the multiprocessing mode (-jN command line option) if process groups are available: if os.setsid() and os.killpg() functions are available.
* bpo-27657: Fix urlparse() with numeric paths (#661)Tim Graham2019-10-181-0/+2
| | | | | | | | | | * bpo-27657: Fix urlparse() with numeric paths Revert parsing decision from bpo-754016 in favor of the documented consensus in bpo-16932 of how to treat strings without a // to designate the netloc. * bpo-22891: Remove urlsplit() optimization for 'http' prefixed inputs.

* bpo-33604: Raise TypeError on missing hmac arg. (GH-16805)Gregory P. Smith2019-10-181-0/+3
| | | | | | | | | | Also updates the documentation to clarify the situation surrounding the digestmod parameter that is required despite its position in the argument list as of 3.8.0 as well as removing old python2 era references to "binary strings". We indavertently had this raise ValueError in 3.8.0 for the missing arg. This is not considered an API change as no reasonable code would be catching this missing argument error in order to handle it.
* bpo-37587: json: Use _PyUnicodeWriter when scanning string. (GH-15591)Inada Naoki2019-10-171-0/+2

* bpo-35998: Fix test_asyncio.test_start_tls_server_1() (GH-16815)Victor Stinner2019-10-161-0/+5
| | | | | | | | | | main() is now responsible to send the ANSWER, rather than ServerProto. main() now waits until it got the HELLO before sending the ANSWER over the new transport. Previously, there was a race condition between main() replacing the protocol and the protocol sending the ANSWER once it gets the HELLO. TLSv1.3 was disabled for the test: reenable it.
* bpo-38468 : Refactor python-config (#16749)Joannah Nanjekye2019-10-152-5/+7

* bpo-37961, tracemalloc: add Traceback.total_nframe (GH-15545)Julien Danjou2019-10-151-0/+2
| | | | Add a total_nframe field to the traces collected by the tracemalloc module. This field indicates the original number of frames before it was truncated.

* bpo-38470: Fix test_compileall.test_compile_dir_maxlevels() (GH-16789)Victor Stinner2019-10-151-0/+3
| | | | | | | | | Fix test_compile_dir_maxlevels() on Windows without long path support: only create 3 subdirectories instead of between 20 and 100 subdirectories. Fix also compile_dir() to use the current sys.getrecursionlimit() value as the default maxlevels value, rather than using sys.getrecursionlimit() value read at startup.
* bpo-11410: Standardize and use symbol visibility attributes across POSIX and ↵Vinay Sajip2019-10-151-0/+4
| | | | Windows. (GH-16347)
* bpo-32498: urllib.parse.unquote also accepts bytes (GH-7768)Stein Karlsen2019-10-141-0/+2

* bpo-38469: Handle named expression scope with global/nonlocal keywords ↵Pablo Galindo2019-10-141-0/+2
| | | | | (GH-16755) The symbol table handing of PEP572's assignment expressions is not resolving correctly the scope of some variables in presence of global/nonlocal keywords in conjunction with comprehensions.
* bpo-38379: Don't block collection of unreachable objects when some objects ↵Pablo Galindo2019-10-131-0/+4
| | | | | | | resurrect (GH-16687) Currently if any finalizer invoked during garbage collection resurrects any object, the gc gives up and aborts the collection. Although finalizers are assured to only run once per object, this behaviour of the gc can lead to an ever-increasing memory situation if new resurrecting objects are allocated in every new gc collection. To avoid this, recompute what objects among the unreachable set need to be resurrected and what objects can be safely collected. In this way, resurrecting objects will not block the collection of other objects in the unreachable set.
* bpo-38431: Fix __repr__ method of InitVar to work with typing objects. ↵Samuel Colvin2019-10-131-0/+1
| | | | | | (GH-16702)
* bpo-38378: Rename parameters "out" and "in" of os.sendfile(). (GH-16742)Serhiy Storchaka2019-10-131-0/+2
| | | | | | | They conflicted with keyword "in". Also rename positional-only parameters of private os._fcopyfile() for consistency.
* bpo-38417: Add umask support to subprocess (GH-16726)Gregory P. Smith2019-10-121-0/+2
| | | | On POSIX systems, allow the umask to be set in the child process before we exec.
* bpo-35800: Deprecate smtpd.MailmanProxy (GH-11675)Samuel Colvin2019-10-122-0/+2
| | | | | | Since `smtpd.MailmanProxy` is already broken, it is not formally deprecated in 3.9. It will be removed in 3.10. https://bugs.python.org/issue35800
* bpo-38449: Revert "bpo-22347: Update mimetypes.guess_type to allow oper ↵Abhilash Raj2019-10-122-2/+2
| | | | | | | | | parsing of URLs (GH-15522)" (GH-16724) This reverts commit 87bd2071c756188b6cd577889fb1682831142ceb. https://bugs.python.org/issue38449
* bpo-38347: find pathfix for Python scripts whose name contain a '-' (GH-16536)Ruediger Pluem2019-10-111-0/+1
| | | pathfix.py: Assume all files that end on '.py' are Python scripts when working recursively.
* bpo-38437: Activate GC_DEBUG when PY_DEBUG is set (GH-16707)Pablo Galindo2019-10-101-0/+2
|
* bpo-38109: Add missing constants to Lib/stat.py (GH-16665)Ronan Lamy2019-10-101-0/+3
| | | | | Add missing stat.S_IFDOOR, stat.S_IFPORT, stat.S_IFWHT, stat.S_ISDOOR, stat.S_ISPORT, and stat.S_ISWHT values to the Python implementation of the stat module.
* bpo-38379: don't claim objects are collected when they aren't (#16658)Tim Peters2019-10-091-0/+1
| | | | | | * bpo-38379: when a finalizer resurrects an object, nothing is actually collected in this run of gc. Change the stats to relect that truth.
* closes bpo-36161: Use thread-safe ttyname_r instead of ttyname. (GH-14868)Antonio Gutierrez2019-10-091-0/+1

* bpo-37531: regrtest ignores output on timeout (GH-16659)Victor Stinner2019-10-081-0/+5
| | | | | | | | | | | bpo-37531, bpo-38207: On timeout, regrtest no longer attempts to call `popen.communicate() again: it can hang until all child processes using stdout and stderr pipes completes. Kill the worker process and ignores its output. Reenable test_regrtest.test_multiprocessing_timeout(). bpo-37531: Change also the faulthandler timeout of the main process from 1 minute to 5 minutes, for Python slowest buildbots.
* bpo-38395: Fix ownership in weakref.proxy methods (GH-16632)Pablo Galindo2019-10-081-0/+3
| | | | | | | | | | | | | The implementation of weakref.proxy's methods call back into the Python API using a borrowed references of the weakly referenced object (acquired via PyWeakref_GET_OBJECT). This API call may delete the last reference to the object (either directly or via GC), leaving a dangling pointer, which can be subsequently dereferenced. To fix this, claim a temporary ownership of the referenced object when calling the appropriate method. Some functions because at the moment they do not need to access the borrowed referent, but to protect against future changes to these functions, ownership need to be fixed in all potentially affected methods.
* bpo-38118: Ignore Valgrind false alarm in PyUnicode_Decode() (GH-16651)Victor Stinner2019-10-082-0/+13
| | | | | | | Valgrind emits "Conditional jump or move depends on uninitialised value(s)" false alarms on GCC builtin strcmp() function. The GCC code is correct. Valgrind bug: https://bugs.kde.org/show_bug.cgi?id=264936
* bpo-38405: Make nested subclasses of typing.NamedTuple pickleable. (GH-16641)Serhiy Storchaka2019-10-081-0/+1
|
* bpo-36698: IDLE no longer fails when write non-encodable characters to ↵Serhiy Storchaka2019-10-081-0/+3
| | | | | | | stderr. (GH-16583) It now escapes them with a backslash, as the regular Python interpreter. Added the "errors" field to the standard streams.
* bpo-38371: Tkinter: deprecate the split() method. (GH-16584)Serhiy Storchaka2019-10-081-0/+3
|
* closes bpo-38402: Check error of primitive crypt/crypt_r. (GH-16599)Antonio Gutierrez2019-10-081-0/+1
| | | | | | | Checks also for encryption algorithms methods not supported in different OSs. Signed-off-by: Antonio Gutierrez <chibby0ne@gmail.com>
* bpo-38392: PyObject_GC_Track() validates object in debug mode (GH-16615)Victor Stinner2019-10-071-0/+3
| | | | | | | | In debug mode, PyObject_GC_Track() now calls tp_traverse() of the object type to ensure that the object is valid: test that objects visited by tp_traverse() are valid. Fix pyexpat.c: only track the parser in the GC once the parser is fully initialized.
* bpo-38344: Fix syntax in activate.bat (GH-16533)James Abel2019-10-071-0/+1
|
* bpo-38294: Add list of no-longer-escaped chars to re.escape documentation. ↵Ricardo Bánffy2019-10-071-0/+1
| | | | | | | | | (GH-16442) Prior to 3.7, re.escape escaped many characters that don't have special meaning in Python, but that use to require escaping in other tools and languages. This commit aims to make it clear which characters were, but are no longer escaped.
* bpo-36389: _PyObject_CheckConsistency() available in release mode (GH-16612)Victor Stinner2019-10-071-0/+3
| | | | | | | | | | | | | | | | | | | | | bpo-36389, bpo-38376: The _PyObject_CheckConsistency() function is now also available in release mode. For example, it can be used to debug a crash in the visit_decref() function of the GC. Modify the following functions to also work in release mode: * _PyDict_CheckConsistency() * _PyObject_CheckConsistency() * _PyType_CheckConsistency() * _PyUnicode_CheckConsistency() Other changes: * _PyMem_IsPtrFreed(ptr) now also returns 1 if ptr is NULL (equals to 0). * _PyBytesWriter_CheckConsistency() now returns 1 and is only used with assert(). * Reorder _PyObject_Dump() to write safe fields first, and only attempt to render repr() at the end.
