| | | | | | | | * Added new opcode END_ASYNC_FOR. * Setting global StopAsyncIteration no longer breaks "async for" loops. * Jumping into an "async for" loop is now disabled. * Jumping out of an "async for" loop no longer corrupts the stack. * Simplify the compiler.

* bpo-31453: Add setter for min/max protocol version (#5259)Christian Heimes2018-02-271-0/+5
| | | | | | | | | | | | OpenSSL 1.1 has introduced a new API to set the minimum and maximum supported protocol version. The API is easier to use than the old OP_NO_TLS1 option flags, too. Since OpenSSL has no call to set minimum version to highest supported, the implementation emulate maximum_version = MINIMUM_SUPPORTED and minimum_version = MAXIMUM_SUPPORTED by figuring out the minumum and maximum supported version at compile time.

* bpo-32951: Disable SSLSocket/SSLObject constructor (#5864)Christian Heimes2018-02-271-0/+6
| | | | | | | | | | | | | | | | Direct instantiation of SSLSocket and SSLObject objects is now prohibited. The constructors were never documented, tested, or designed as public constructors. The SSLSocket constructor had limitations. For example it was not possible to enabled hostname verification except was ssl_version=PROTOCOL_TLS_CLIENT with cert_reqs=CERT_REQUIRED. SSLContext.wrap_socket() and SSLContext.wrap_bio are the recommended API to construct SSLSocket and SSLObject instances. ssl.wrap_socket() is also deprecated. The only test case for direct instantiation was added a couple of days ago for IDNA testing. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-28124: deprecate ssl.wrap_socket() (#5888)Christian Heimes2018-02-271-0/+5
| | | | | | | The ssl module function ssl.wrap_socket() has been de-emphasized and deprecated in favor of the more secure and efficient SSLContext.wrap_socket() method. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-32947: OpenSSL 1.1.1-pre1 / TLS 1.3 fixes (#5663)Christian Heimes2018-02-271-0/+3
| | | | | | | | | | | | | | | | | | * bpo-32947: OpenSSL 1.1.1-pre1 / TLS 1.3 fixes Misc fixes and workarounds for compatibility with OpenSSL 1.1.1-pre1 and TLS 1.3 support. With OpenSSL 1.1.1, Python negotiates TLS 1.3 by default. Some test cases only apply to TLS 1.2. Other tests currently fail because the threaded or async test servers stop after failure. I'm going to address these issues when OpenSSL 1.1.1 reaches beta. OpenSSL 1.1.1 has added a new option OP_ENABLE_MIDDLEBOX_COMPAT for TLS 1.3. The feature is enabled by default for maximum compatibility with broken middle boxes. Users should be able to disable the hack and CPython's test suite needs it to verify default options.

* [bpo-28414] Make all hostnames in SSL module IDN A-labels (GH-5128)Christian Heimes2018-02-241-0/+8
| | | | | | | | | | | | Previously, the ssl module stored international domain names (IDNs) as U-labels. This is problematic for a number of reasons -- for example, it made it impossible for users to use a different version of IDNA than the one built into Python. After this change, we always convert to A-labels as soon as possible, and use them for all internal processing. In particular, server_hostname attribute is now an A-label, and on the server side there's a new sni_callback that receives the SNI servername as an A-label rather than a U-label.

* bpo-31429: Define TLS cipher suite on build time (#3532)Christian Heimes2018-01-291-0/+6
| | | | | | | | | | | | | Until now Python used a hard coded white list of default TLS cipher suites. The old approach has multiple downsides. OpenSSL's default selection was completely overruled. Python did neither benefit from new cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites. For example we used to re-enable 3DES. Python now defaults to OpenSSL DEFAULT cipher suite selection and black lists all unwanted ciphers. Downstream vendors can override the default cipher list with --with-ssl-default-suites.

| | | | | | | | | | | | | | | bpo-31399: Let OpenSSL verify hostname and IP The ssl module now uses OpenSSL's X509_VERIFY_PARAM_set1_host() and X509_VERIFY_PARAM_set1_ip() API to verify hostname and IP addresses. * Remove match_hostname calls * Check for libssl with set1_host, libssl must provide X509_VERIFY_PARAM_set1_host() * Add documentation for OpenSSL 1.0.2 requirement * Don't support OpenSSL special mode with a leading dot, e.g. ".example.org" matches "www.example.org".

* bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)Nick Coghlan2018-01-081-0/+40
| | | | | | | | | | | | | - primary change is to add a new default filter entry for 'default::DeprecationWarning:__main__' - secondary change is an internal one to cope with plain strings in the warning module's internal filter list (this avoids the need to create a compiled regex object early on during interpreter startup) - assorted documentation updates, including many more examples of configuring the warnings settings - additional tests to ensure that both the pure Python and the C accelerated warnings modules have the expected default configuration
* bpo-32206: Pdb can now run modules (GH-4752)Mario Corchero2018-01-061-0/+4
| | | | | | | | | | | Add a new argument "-m" to the pdb module to allow users to run `python -m pdb -m my_module_name`. This relies on private APIs in the runpy module to work, but we can get away with that since they're both part of the standard library and can be updated together if the runpy internals get refactored.
