* 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.

* 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-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-38392: PyObject_GC_Track() validates object in debug mode (GH-16615)Victor Stinner2019-10-081-0/+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.

* bpo-13153: Use OS native encoding for converting between Python and Tcl. ↵Serhiy Storchaka2019-10-041-0/+4
| | | | | | | | | | | | | (GH-16545) On Windows use UTF-16 (or UTF-32 for 32-bit Tcl_UniChar) with the "surrogatepass" error handler for converting to/from Tcl Unicode objects. On Linux use UTF-8 with the "surrogateescape" error handler for converting to/from Tcl String objects. Converting strings from Tcl to Python and back now never fails (except MemoryError).

* bpo-37474: Don't call fedisableexcept() on FreeBSD (GH-16515)Victor Stinner2019-10-011-0/+3
| | | | | On FreeBSD, Python no longer calls fedisableexcept() at startup to control the floating point control mode. The call became useless since FreeBSD 6: it became the default mode.
* bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)Victor Stinner2019-10-011-3/+0
| | | | | | | For now, we'll rely on the fact that the config structures aren't covered by the stable ABI. We may revisit this in the future if we further explore the idea of offering a stable embedding API. (cherry picked from commit bdace21b769998396d0ccc8da99a8ca9b507bfdf)

This bug has affected many people and in some cases has been a dealbreaker to the adoption of the otherwise wonderful pathlib and PEP519. https://stackoverflow.com/questions/33625931/copy-file-with-pathlib-in-python.

I'm not sure if the idea is for all these modules to strictly avoid circular dependencies. They are already using os.path which is just as much a citizen in 3.8 as pathlib right? e.g. `real_dst = os.path.join(dst, _basename(src))` becomes `real_dst = Path(dst) / Path(src).name` I've looked around and familiarized myself, and I now think importing pathlib here is fine. My only remaining concern is that of performance. Here's the performance difference for this step. ``` In [46]: %timeit real_dst = os.path.join("a/b/c", _basename('b/')) 2.71 µs ± 62.6 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) In [47]: %timeit real_dst = Path("a/b/c") / Path('b/').name 12.4 µs ± 65.3 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each) ``` Is 10us significant or insignificant compared to the least expensive operation this function will do? I don't know. Let's find out. ``` In [55]: %timeit os.rename('/tmp/a/a.txt', '/tmp/a/b.txt'); os.rename('/tmp/a/b.txt', '/tmp/a/a.txt') 124 µs ± 2.18 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each) ``` 62us to rename. 10us seems significant enough that we wouldn't want to favor the Path sugar suggestion. 16% speed decrease from adding the 10us. What do people think? I was hoping to get to use pathlib.Path here, but I suspect for this low level move, it should be as fast as possible, and 16% is not worth one line of sugary code to me. https://bugs.python.org/issue32689 Automerge-Triggered-By: @gvanrossum

| | | | | | | | | | Document that lnotab can contain invalid bytecode offsets (because of terrible reasons that are difficult to fix). Make dis.findlinestarts() ignore invalid offsets in lnotab. All other uses of lnotab in CPython (various reimplementations of addr2line or line2addr in Python, C and gdb) already ignore this, because they take an address to look for, instead. Add tests for the result of dis.findlinestarts() on wacky constructs in test_peepholer.py, because it's the easiest place to add them.

Now, you can: - Strip a part of path from a beggining of path into compiled file example "-s /test /test/build/real/test.py" → "build/real/test.py" - Append some new path to a beggining of path into compiled file example "-p /boo real/test.py" → "/boo/real/test.py" You can also use both options in the same time. In that case, striping is done before appending. * Add a possibility to specify multiple optimization levels Each optimization level then leads to separated compiled file. Use `action='append'` instead of `nargs='+'` for the -o option. Instead of `-o 0 1 2`, specify `-o 0 -o 1 -o 2`. It's more to type, but much more explicit. * Add a symlinks limitation feature This feature allows us to limit byte-compilation of symbolic links if they are pointing outside specified dir (build root for example).
