[issue27850] Remove 3DES from cipher list (sweet32 CVE-2016-2183)

[Cory Benfield]

Cory Benfield added the comment:

Thanks for your response Larry. I think it cleared up my understanding a bit, 
and I'm (extremely!) sympathetic to your desire to not get any closer to this 
problem than you have to.

I think it may be worth, in future, defining what effort will be made to 
achieve compatibility with libraries that Python relies on. I can see several 
questions here that, AFAIK, have no concrete answer:

- Can a Python minor version increase (e.g. 3.6 -> 3.7) add support for a new 
ABI in a library dependency? (This one has an answer, which is certainly yes, 
but we could still stand to write it down because you'd be amazed how often it 
helps to write down the basic starting point of the argument.)
- Can a Python patch version increase *before* security release mode (e.g. 
3.6.1 -> 3.6.2) add support for a new ABI in a library dependency?
- What about a new API that maintains ABI compatibility?
- Can a Python security version increase (e.g. 3.4.5 -> 3.4.6) add support for 
a new ABI in a library dependency?
- What about a new API that maintains ABI compatibility?
- How do the answers to the above questions vary if the change is 
security-focused (e.g. AES is broken tomorrow so ChaCha20 is the only safe 
cipher left in OpenSSL)?

I'm not qualified or authoritative enough to answer those questions, but having 
an answer to them would help modulate expectations from people like myself.

[issue28005] Broken encoding modules are silently skipped.

[Marc-Andre Lemburg]

Marc-Andre Lemburg added the comment:

Thinking about this some, we could go ahead and document somewhere that if a 
codec wants to tell the search function that it cannot work due to some missing 
dependency, it will have to raise an ImportError from the codec module level 
(instead of just lettering ImportError bubble up), possibly reraising the error 
to assure this.

[issue28015] configure --with-lto builds fail when CC=clang on Linux, requires gold linker

[Gregory P. Smith]

New submission from Gregory P. Smith:

The error message you will see when building may look something like:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Makefile:793: recipe for target 'Parser/pgen' failed

as seen on ubuntu 16.04.

Related to 
https://bugs.launchpad.net/ubuntu/+source/llvm-toolchain-snapshot/+bug/1254970 
which suggests we also need -B/usr/lib/gold-ld in our LDFLAGS and/or CFLAGS 
when using clang on Linux with LTO.

testing with it set in both still runs into errors; someone with clang LTO 
experience will need to untangle this.

(is this related to why --with-lto doesn't work on MacOS as well?)

/dev/tty is seakable on AIX, like on some other Unix on wich this assertion is

[issue28017] bluetooth.h on big endian needs GNU C extensions

[Christian Heimes]

New submission from Christian Heimes:

PPC Fedora build bot is not able to build the _ssl and _socket module. It looks 
like bluetooth.h is not compatible with std=c99. It uses some GNU C extensions 
like __extension__, __attribute__((packed)) and __typeof__. The C99 variant 
-std=gnu99 should do the trick.

[issue28016] test_fileio fails on AIX

[Martin Panter]

Martin Panter added the comment:

You should be able to provide a tuple of prefixes (I can easily change to that 
change when I commit):

not sys.platform.startswith(('sunos', 'aix'))

However I noticed the AIX buildbots are all passing test_fileio. I wonder what 
the difference is? Maybe the buildbot process doesn’t have a /dev/tty and skips 
the test.

Would this also be needed on 2.7? The test seems to be called testAblesOnTTY() 
there.

[issue28018] Cross compilation fails in regen

[Chi Hsuan Yen]

New submission from Chi Hsuan Yen:

Since issue23968 landed (changeset 5c77488830bc), cross compilation fails. It's 
not regression of a single revision but is caused by a combination of multiple 
changes. Here are my steps:

1. git clone https://github.com/yan12125/python3-android
2. comment `patch -p1 < "${FILESDIR}/cross-compile.patch"` from

3. `make`

bash (I'm using 4.3.046) does not parse environment variables in quotation 
marks. For example the following script fails:

FOO="BAR=1 ls"
$FOO

The attached patch makes regen work again. I see /usr/bin/env used everywhere 
in CPython, so I guess it's OK to use it in configure without loss of 
portability.

Also added some people from issue14330, where $PYTHON_FOR_BUILD appeared for 
the first time.

sent to the address you have registered with as "jojo".


So your config.log confirms that the configure script does use 
${exec_prefix}/lib64.
Your system may be configured with a configure system-wide initialization file 
[1]. In that case, configure will print a line starting with:
"loading site script ..."
and showing the path to the config.site file that is being loaded. As described 
at the end of [1], this is where libdir may be set to '${exec_prefix}/lib64'.

[issue1602] windows console doesn't print or input Unicode

[Martin Panter]

Martin Panter added the comment:

+++ b/Lib/test/test_winconsoleio.py
+to real people with real keyborads.
Should be keyboards
There are still assert_() calls in this file (1602_6.patch). Did you miss them?

+++ b/Lib/io.py
+from _io import WindowsConsoleIO
+__all__.append('WindowsConsoleIO')
I think you should either document this class, or remove it from __all__ to 
clarify it is just an implementation detail.

+++ b/Modules/_io/winconsoleio.c
+_io_WindowsConsoleIO___init___impl
+PyObject *decodedname = Py_None;
+Py_INCREF(decodedname);
+int d = PyUnicode_FSDecoder(nameobj, (void*)&decodedname);
Won’t this leak a reference to Py_None?
(Also, I think needless casting like in the last line can mask mistakes that 
the compiler would otherwise pick up. Imagine if you got the parameters around 
the wrong way.)

+read_console_w(HANDLE handle, DWORD maxlen, DWORD *readlen) {
+/* If we didn't read a full buffer that time, don't try
+   again or we will block a second time. */
I’m not familiar with the Windows APIs involved, but this doesn’t seem robust. 
What if there were exactly one full buffer waiting, would the next call block 
without returning anything?

[issue28019] itertools.count() falls back to fast (integer) mode when step rounds to 1

[Marcos Dione]

New submission from Marcos Dione:

If the `step` parameter for `itertools.count()` rounds to 1 (f.i., 1.1, 
1.437643, 1.9), then it fallsback to fast (integer) mode and increases the 
counter by 1. Here's an example:

Python 3.6.0a4+ (default:ddc95a9bc2e0+, Sep  8 2016, 14:46:19)
>>> import itertools
>>> for i in itertools.count(1, step=1.5):
... print(i)
... if i > 10:
... break
1

[issue28020] Python 3 logging HTTPHandler doesn't implement a standard http basic authorize

[SenBin Yu]

New submission from SenBin Yu:

The standard http basic authorization is

basic-credentials = "Basic" SP basic-cookie

basic-cookie  = 

userid-password   = [ token ] ":" *TEXT

but the logging/handlers module do the fllowing:

s = ('u%s:%s' % self.credentials).encode('utf-8')

s = 'Basic ' + base64.b64encode(s).strip()

why there is a redundant chr 'u'?

[issue28005] Broken encoding modules are silently skipped.

[Steve Dower]

Steve Dower added the comment:

Is it deliberate that inner import errors should be treated as if the codec is 
missing? Another search function isn't going to help in that case unless it 
finds the same encoding in another place. I didn't see any evidence of that, 
and apparently neither did Eric (but I was bitten by a misspelt import within 
my new encodings/oem.py giving a confusing message).

I don't think any encoding modules in the stdlib should fail to import. This 
change ensures that we hear about it if they do fail.

[issue28019] itertools.count() falls back to fast (integer) mode when step rounds to 1

[Facundo Batista]

Facundo Batista added the comment:

I think the fix nails it; all the problem was that the "fast" mode was wrongly 
detected, and all the problems (counting badly, or a bad repr, etc) is a 
problem after setting cnt into PY_SSIZE_T_MAX.

IIUC there is nothing special to do when step=1.0, as later on the original 
objects are used (they don't suffer a wrong cast to integer anymore).

[issue20994] Disable TLS Compression

the default context sets context.options |= getattr(_ssl, "OP_NO_COMPRESSION",

[issue23033] Disallow support for a*.example.net, *a.example.net, and a*b.example.net in certificate wildcard handling.

[Christian Heimes]

Christian Heimes added the comment:

Sounds good to me!

For 3.7 I'm planning to use OpenSSL's hostname verification system and 
deprecate match_hostname(). It does support partial matching by default.

It's 2016. Everybody should have a host with Python 3. In fact it's more likely

[issue28022] SSL releated deprecation for 3.6

[Christian Heimes]

New submission from Christian Heimes:

I like to deprecate some SSL related parts of Python:

- ssl.wrap_socket() is a horrible abomination. People should use 
SSLContext.wrap_socket() instead
- all certfile/cert_file, keyfile/key_file and check_hostname arguments. Use 
context / ssl_context instead.
- make ftplib, imaplib, nntplib, pop3lib, smtplib etc. validate certs by 
default.

[issue23843] ssl.wrap_socket doesn't handle virtual TLS hosts

[Christian Heimes]

Christian Heimes added the comment:

ssl.wrap_socket() will be deprecated in 3.6. Please use a context. You can 
still inspect the server cert with a context. In fact ssl.wrap_socket() uses a 
context internally.

[issue24372] Documentation for ssl.wrap_socket's ssl_version parameter is odd

[Christian Heimes]

Christian Heimes added the comment:

OpenSSL 1.1.0 has deprecated all versions except TLS_METHOD and DTLS_METHOD. 
TLS_METHOD is the new name for auto-nego SSLv23_METHOD. Python 3.6 defaults to 
TLS_METHOD already. #27876 will add a better way to configure accepted versions.
