* bpo-32374: m_traverse may be called with m_state=NULL (GH-5140)Marcel Plch2018-03-175-7/+96
| | | | | Multi-phase initialized modules allow m_traverse to be called while the module is still being initialized, so module authors may need to account for that.
* bpo-33021: Fix GCC 7 warning (-Wmaybe-uninitialized) in mmapmodule.c (#6117)Zackery Spytz2018-03-141-1/+1

* bpo-17288: Prevent jumps from 'return' and 'exception' trace events. (GH-6107)xdegaye2018-03-133-15/+93
| | | (cherry picked from commit e32bbaf376a09c149fa7c7f2919d7c9ce4e2a055)
* bpo-32885: Tools/scripts/pathfix.py: Add -n option for no backup~ (#5772)Miro Hrončok2018-03-133-8/+23
| | | | | | | Creating backup files with ~ suffix can be undesirable in some environment, such as when building RPM packages. Instead of requiring the user to remove those files manually, option -n was added, that simply disables this feature. -n was selected because 2to3 has the same option with this behavior.
* bpo-33064: lib2to3: support trailing comma after *args and **kwargs (#6096)Łukasz Langa2018-03-133-26/+39
| | | | | | | New tests also added. I also made the comments in line with the builtin Grammar/Grammar. PEP 306 was withdrawn, Kees Blom's railroad program has been lost to the sands of time for at least 16 years now (I found a python-dev post from people looking for it).

* bpo-33021: Release the GIL during fstat() calls (GH-6019)Nir Soffer2018-03-113-3/+17
| | | | | | | | | | | | | | fstat may block for long time if the file descriptor is on a non-responsive NFS server, hanging all threads. Most fstat() calls are handled by _Py_fstat(), releasing the GIL internally, but but _Py_fstat_noraise() does not release the GIL, and most calls release the GIL explicitly around it. This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs when calling: - mmap.mmap() - os.urandom() - random.seed()
* bpo-31804: Fix multiprocessing.Process with broken standard streams (#6079)Antoine Pitrou2018-03-115-12/+47
| | | | | In some conditions the standard streams will be None or closed in the child process (for example if using "pythonw" instead of "python" on Windows). Avoid failing with a non-0 exit code in those conditions. Report and initial patch by poxthegreat.

| | | | | | | | Fix a crash on fork when using a custom memory allocator (ex: using PYTHONMALLOC env var). _PyGILState_Reinit() and _PyInterpreterState_Enable() now use the default RAW memory allocator to allocate a new interpreters mutex on fork.
* Fix strncpy warning with gcc 8 (#5840)Siddhesh Poyarekar2018-03-061-2/+2
| | | | | The length in strncpy is one char too short and as a result it leads to a build warning with gcc 8. Comment out the strncpy since the interpreter aborts immediately after anyway.

* bpo-32984: IDLE - set __file__ for startup files (GH-5981)Terry Jan Reedy2018-03-052-0/+10
| | | | | | | | | Like Python, IDLE optionally runs one startup file in the Shell window before presenting the first interactive input prompt. For IDLE, option -s runs a file named in environmental variable IDLESTARTUP or PYTHONSTARTUP; -r file runs file. Python sets __file__ to the startup file name before running the file and unsets it before the first prompt. IDLE now does the same when run normally, without the -n option.

* bpo-32981: Fix catastrophic backtracking vulns (#5955)Jamie Davis2018-03-046-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Prevent low-grade poplib REDOS (CVE-2018-1060) The regex to test a mail server's timestamp is susceptible to catastrophic backtracking on long evil responses from the server. Happily, the maximum length of malicious inputs is 2K thanks to a limit introduced in the fix for CVE-2013-1752. A 2KB evil response from the mail server would result in small slowdowns (milliseconds vs. microseconds) accumulated over many apop calls. This is a potential DOS vector via accumulated slowdowns. Replace it with a similar non-vulnerable regex. The new regex is RFC compliant. The old regex was non-compliant in edge cases. * Prevent difflib REDOS (CVE-2018-1061) The default regex for IS_LINE_JUNK is susceptible to catastrophic backtracking. This is a potential DOS vector. Replace it with an equivalent non-vulnerable regex. Also introduce unit and REDOS tests for difflib.
