Log message:
python3[4567]: find_library() fixes; remove -stack_size from LDFLAGS on Darwin.

PkgSrc changes:
* Make find_library() consitant for all Python versions:
  - Fallback to clang, when gcc is not installed.
  - Find libraries in PkgSrc prefix.
* Do not use -stack_size; it ends up in 'pythonNN-config --ldflags', and some
  modules fail to build.

python36: updated to 3.6.8

Python 3.6.8 final

Library
- bpo-31715: Associate .mjs file extension with application/javascript MIME Type.

Build
- bpo-35499: make profile-opt no longer replaces CFLAGS_NODIST with CFLAGS. It \ 
now adds profile-guided optimization (PGO) flags to CFLAGS_NODIST: existing \ 
CFLAGS_NODIST flags are kept.
- bpo-35257: Avoid leaking the linker flags from Link Time Optimizations (LTO) \ 
into distutils when compiling C extensions.

C API
- bpo-35259: Conditionally declare Py_FinalizeEx() (new in 3.6) based on \ 
Py_LIMITED_API.

Python 3.6.8 release candidate 1

Security
- bpo-34812: The -I command line option (run Python in isolated mode) is now \ 
also copied by the multiprocessing and distutils modules when spawning child \ 
processes. Previously, only -E and -s options (enabled by -I) were copied.
- bpo-34791: The xml.sax and xml.dom.domreg no longer use environment variables \ 
to override parser implementations when sys.flags.ignore_environment is set by \ 
-E or -I arguments.

Core and Builtins
- bpo-35444: Fixed error handling in pickling methods when fail to look up \ 
builtin “getattr”.
- bpo-35436: Fix various issues with memory allocation error handling. Patch by \ 
Zackery Spytz.
- bpo-35357: Internal attributes’ names of unittest.mock._Call and \ 
unittest.mock.MagicProxy (name, parent & from_kall) are now prefixed with \ 
_mock_ in order to prevent clashes with widely used object attributes. Fixed \ 
minor typo in test function name.
- bpo-35372: Fixed the code page decoder for input longer than 2 GiB containing \ 
undecodable bytes.
- bpo-33954: For str.format(), float.__format__() and complex.__format__() \ 
methods for non-ASCII decimal point when using the “n” formatter.
- bpo-35214: Fixed an out of bounds memory access when parsing a truncated \ 
unicode escape sequence at the end of a string such as '\N'. It would read one \ 
byte beyond the end of the memory allocation.
- bpo-35214: The interpreter and extension modules have had annotations added so \ 
that they work properly under clang’s Memory Sanitizer. A new configure flag \ 
–with-memory-sanitizer has been added to make test builds of this nature \ 
easier to perform.
- bpo-35193: Fix an off by one error in the bytecode peephole optimizer where it \ 
could read bytes beyond the end of bounds of an array when removing unreachable \ 
code. This bug was present in every release of Python 3.6 until now.
- bpo-29341: Clarify in the docstrings of os methods that path-like objects are \ 
also accepted as input parameters.
- bpo-35050: socket: Fix off-by-one bug in length check for AF_ALG name and type.

and return the result of using the side effect the same way that it is done with \ 
return_value.
- bpo-34172: Revert the fix for this issue previously released in 3.6.7 pending \ 
further investigation: Fix a reference issue inside multiprocessing.Pool that \ 
caused the pool to remain alive if it was deleted without being closed or \ 
terminated explicitly.
- bpo-10496: posixpath.expanduser() now returns the input path unchanged if the \ 
HOME environment variable is not set and the current user has no home directory \ 
(if the current user identifier doesn’t exist in the password database). This \ 
change fix the site module if the current user doesn’t exist in the password \ 
database (if the user has no home directory).
- bpo-35310: Fix a bug in select.select() where, in some cases, the file \ 
descriptor sequences were returned unmodified after a signal interruption, even \

- bpo-28604: locale.localeconv() now sets temporarily the LC_CTYPE locale to the \ 
LC_MONETARY locale if the two locales are different and monetary strings are \ 
non-ASCII. This temporary change affects other threads.
- bpo-35277: Update ensurepip to install pip 18.1 and setuptools 40.6.2.
- bpo-35226: Recursively check arguments when testing for equality of \ 
unittest.mock.call objects and add note that tracking of parameters used to \ 
create ancestors of mocks in mock_calls is not possible.

signal (EINTR): flock, lockf, fnctl
- bpo-35062: Fix incorrect parsing of _io.IncrementalNewlineDecoder’s \ 
translate argument.
- bpo-35079: Improve difflib.SequenceManager.get_matching_blocks doc by adding \

* Fixed reset of the SIGINT handler to SIG_DFL on interpreter shutdown even when \ 
there was a custom handler set previously.
* Fixed a leak when the garbage collector fails to add an object with the \ 
__del__ method or referenced by it into the gc.garbage list. PyGC_Collect() can \ 
now be called when an exception is set and preserves it.

key-sharing dict.
* Fixed jumping when the function contains an async for loop.
* Fix an unnecessary ifdef in the include of VersionHelpers.h in socketmodule on \

TypeError instead of SystemError when performed on mmap.mmap objects.
* Fix gather to propagate cancellation of itself even with return_exceptions.
* Fix a race condition in SSLProtocol.connection_made() of asyncio.sslproto: \ 
start immediately the handshake instead of using call_soon(). Previously, \ 
data_received() could be called before the handshake started, causing the \ 
handshake to hang or fail.
* Fixed bug where calling write_eof() on a _SelectorSocketTransport after it’s \ 
already closed raises AttributeError.
* Fix Task.__repr__ crash with Cython’s bogus coroutines
* Fix RuntimeError after closing loop that used run_in_executor

the cache of parsed strings from clearing after finishing the decoding. Based on \ 
patch by c-fos.
* tempfile._candidate_tempdir_list should consider common TEMP locations
* Prevent uuid.get_node from using a DUID instead of a MAC on Windows.

* random.Random.choice() now raises IndexError for empty sequences consistently \ 
even when called from subclasses without a getrandbits() implementation.
* Update difflib.mdiff() for PEP 479. Convert an uncaught StopIteration in a \ 
generator into a return-statement.
* End framing at the end of C implementation of pickle.Pickler.dump().
* The urllib.robotparser’s __str__ representation now includes wildcard \ 
entries and the “Crawl-delay” and “Request-rate” fields.
* Allow ttk.Treeview.insert to insert iid that has a false boolean value. Note \ 
iid=0 and iid=False would be same.
* The ssl module now compiles with LibreSSL 2.7.1.
* Release the GIL during fstat() calls, avoiding hang of all threads when \ 
calling mmap.mmap(), os.urandom(), and random.seed().

addresses.
* Fix wrong redirection of a low descriptor (0 or 1) to stderr in subprocess if \ 
another low descriptor is closed.

emitted cover files only when --missing option was used.
* If nested log adapters are used, the inner process() methods are no longer omitted.
* Support arrays >=2GiB in ctypes.
* pydoc: the stop() method of the private ServerThread class now waits until \ 
DocServer.serve_until_quit() completes and then explicitly sets its docserver \ 
attribute to None to break a reference cycle.

python36: updated to 3.6.5

Python 3.6.5:

Security
* Minimal fix to prevent buffer overrun in os.symlink on Windows
* Regexes in difflib and poplib were vulnerable to catastrophic backtracking. \ 
These regexes formed potential DOS vectors (REDOS). They have been refactored. \ 
This resolves CVE-2018-1060 and CVE-2018-1061.

Core and Builtins
* Fixed jumping out of “with” block by setting f_lineno.
* Prevent jumps from ‘return’ and ‘exception’ trace events.
* Update Valgrind suppression list to account for the rename of \ 
Py_ADDRESS_IN_RANG to address_in_range.
* Pdb and other debuggers dependent on bdb.py will correctly step over (next \ 
command) native coroutines.
* Improve suggestion when the Python 2 form of print statement is either present \ 
on the same line as the header of a compound statement or else terminated by a \ 
semi-colon instead of a newline.
* Fix possible crashing in builtin Unicode decoders caused by write out-of- \ 
bound errors when using customized decode error handlers.
* Improved frozenset() hash to create more distinct hash values when faced with \ 
datasets containing many similar values.
* The __debug__ constant is now optimized out at compile time. This fixes also \ 
bpo-22091.
* sys.flags.hash_randomization is now properly set to 0 when hash randomization \ 
is turned off by PYTHONHASHSEED=0.
* The optimizer is now protected from spending much time doing complex \ 
calculations and consuming much memory for creating large constants in constant \ 
folding.
* repr() on a dict containing its own values() or items() no longer raises \ 
RecursionError; OrderedDict similarly. Instead, use ..., as for other recursive \ 
structures.
* Leading whitespace is now correctly ignored when generating suggestions for \ 
converting Py2 print statements to Py3 builtin print function calls.
* The repr of deeply nested dict now raises a RecursionError instead of crashing \ 
due to a stack overflow.

Library
* lib2to3 now properly supports trailing commas after *args and **kwargs in \ 
function signatures.
* Avoid failing in multiprocessing.Process if the standard streams are closed or \ 
None at exit.
* Skip sending/receiving data after SSL transport closing.
* Fix ctypes pass-by-value for structs on 64-bit Cygwin/MinGW.
* Fix inspect.signature() for single-parameter partialmethods.
* Expose several missing constants in zlib and fix corresponding documentation.
* Fixed tarfile.itn handling of out-of-bounds float values.
* The ssl module now detects missing NPN support in LibreSSL.
* dbm.open() now encodes filename with the filesystem encoding rather than \ 
default encoding.
* In os.dup2, don’t check every call whether the dup3 syscall exists or not.
* Rewrite confusing message from setup.py upload from “No dist file created in \ 
earlier command” to the more helpful “Must create and upload files in one \ 
command”.
* In tkinter, after_cancel(None) now raises a ValueError instead of canceling \ 
the first scheduled function.
* Make sure sys.argv remains as a list when running trace.
* Fixed asyncio.Condition issue which silently ignored cancellation after \ 
notifying and cancelling a conditional lock.
* Fixed refleaks of __init__() methods in various modules. (Contributed by Oren \ 
Milman)
* Fixed guessing quote and delimiter in csv.Sniffer.sniff() when only the last \ 
field is quoted.
* socket: Remove TCP_FASTOPEN, TCP_KEEPCNT flags on older version Windows during \ 
run-time.
* Fix a rare but potential pre-exec child process deadlock in subprocess on \ 
POSIX systems when marking file descriptors inheritable on exec in the child \ 
process. This bug appears to have been introduced in 3.4.
* The ctypes module used to depend on indirect linking for dlopen. The shared \ 
extension is now explicitly linked against libdl on platforms with dl.
* Fixed asyncio.Lock() safety issue which allowed acquiring and locking the same \ 
lock multiple times, without it being free.
* Do not include name field in SMTP envelope from address.
* Fix email address header parsing error when the username is an empty quoted string.
* distutils’ upload command no longer corrupts tar files ending with a CR \ 
byte, and no longer tries to convert CR to CRLF in any of the upload text \ 
fields.
* uuid.uuid1 no longer raises an exception if a 64-bit hardware address is \ 
encountered.
* Fix the error handling in Aifc_read.initfp() when the SSND chunk is not found.
* On FreeBSD and Solaris, os.strerror() now always decode the byte string from \ 
the current locale encoding, rather than using ASCII/surrogateescape in some \ 
cases.
* The nis module is now compatible with new libnsl and headers location.
* Improve ABCMeta._dump_registry() output readability
* glibc has removed Sun RPC. Use replacement libtirpc headers and library in nis \ 
module.
* Ensure that truncate() preserves the file position (as reported by tell()) \ 
after writes longer than the buffer size.
* Don’t unsubscribe signals in asyncio UNIX event loop on interpreter shutdown.
* The SSL module no longer sends IP addresses in SNI TLS extension on platforms \ 
with OpenSSL 1.0.2+ or inet_pton.
* urllib.parse.urlsplit() does not convert zone-id (scope) to lower case for \ 
scoped IPv6 addresses in hostnames now.
* Fix bdist_wininst of distutils for CRT v142: it binary compatible with CRT v140.
* A single empty field is now always quoted when written into a CSV file. This \ 
allows to distinguish an empty row from a row consisting of a single empty \ 
field.
* Raise NotImplementedError instead of SystemError on platforms where chmod(..., \ 
follow_symlinks=False) is not supported.
* The getnode() ip getter now uses ‘ip link’ instead of ‘ip link list’.
* Ensure TCP_NODELAY is set on Linux. Tests by Victor Stinner.
* The locale.localeconv() function now sets temporarily the LC_CTYPE locale to \ 
the LC_NUMERIC locale to decode decimal_point and thousands_sep byte strings if \ 
they are non-ASCII or longer than 1 byte, and the LC_NUMERIC locale is different \ 
than the LC_CTYPE locale. This temporary change affects other threads.
Same change for the str.format() method when formatting a number (int, float, \ 
float and subclasses) with the n type (ex: '{:n}'.format(1234)).
* Importing native path module (posixpath, ntpath) now works even if the os \ 
module still is not imported.

  method. Patch by Oren Milman.

- bpo-30817: PyErr_PrintEx() clears now the ignored exception that may be
  raised by _PySys_SetObjectId(), for example when no memory.

Library
-------
- bpo-28556: Two minor fixes for typing module: allow shallow copying
  instances of generic classes, improve interaction of __init_subclass__
  with generics.

Log message:
python36: Disable libpython3.so.

This is a useless library (we've built it incorrectly for a long time so it
contains no valid symbols) that only creates CONFLICTS with other python3
packages.  No objection on tech-pkg.  Bump PKGREVISION.
