| | | | | | Include sys/sysmacros.h for major(), minor(), and makedev(). GNU C libray plans to remove the functions from sys/types.h. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-30102: Call OPENSSL_add_all_algorithms_noconf (#3112)Christian Heimes2017-09-053-2/+13
| | | | | | | | The ssl and hashlib modules now call OPENSSL_add_all_algorithms_noconf() on OpenSSL < 1.1.0. The function detects CPU features and enables optimizations on some CPU architectures such as POWER8. Patch is based on research from Gustavo Serra Scalet.

* bpo-17852: Maintain a list of BufferedWriter objects. Flush them on exit. ↵Neil Schemenauer2017-09-055-1/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#1908) * Maintain a list of BufferedWriter objects. Flush them on exit. In Python 3, the buffer and the underlying file object are separate and so the order in which objects are finalized matters. This is unlike Python 2 where the file and buffer were a single object and finalization was done for both at the same time. In Python 3, if the file is finalized and closed before the buffer then the data in the buffer is lost. This change adds a doubly linked list of open file buffers. An atexit hook ensures they are flushed before proceeding with interpreter shutdown. This is addition does not remove the need to properly close files as there are other reasons why buffered data could get lost during finalization. Initial patch by Armin Rigo. * Use weakref.WeakSet instead of WeakKeyDictionary. * Simplify buffered double-linked list types. * In _flush_all_writers(), suppress errors from flush(). * Remove NEWS entry, use blurb.

* Add comment to explain the implications of not sorting keywords (#3331)Raymond Hettinger2017-09-051-0/+4
| | | In Python 3.6, sorted() was removed from _make_key() for the lru_cache and instead rely on guaranteed keyword argument order preservation. This makes keyword argument handling faster but it also causes multiple callers with a different keyword argument order to be cached as separate items. Depending on your point of view, this is either a performance regression (increased number of cache misses) or a performance enhancement (faster computation of keys).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Change NPN detection: Version breakdown, support disabled (pre-patch/post-patch): - pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will be defined -> True/False Version breakdown support enabled (pre-patch/post-patch): - pre-1.0.1: OPENSSL_NPN_NEGOTIATED will not be defined -> False/False - 1.0.1 and 1.0.2: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True - 1.1.0+: OPENSSL_NPN_NEGOTIATED will be defined and OPENSSL_NO_NEXTPROTONEG will not be defined -> True/True * Refine NPN guard: - If NPN is disabled, but ALPN is available we need our callback - Make clinic's ssl behave the same way This created a working ssl module for me, with NPN disabled and ALPN enabled for OpenSSL 1.1.0f. Concerns to address: The initial commit for NPN support into OpenSSL [1], had the OPENSSL_NPN_* variables defined inside the OPENSSL_NO_NEXTPROTONEG guard. The question is if that ever made it into a release. This would need an ugly hack, something like: #if defined(OPENSSL_NO_NEXTPROTONEG) && \ !defined(OPENSSL_NPN_NEGOTIATED) # define OPENSSL_NPN_UNSUPPORTED 0 # define OPENSSL_NPN_NEGOTIATED 1 # define OPENSSL_NPN_NO_OVERLAP 2 #endif [1] https://github.com/openssl/openssl/commit/68b33cc5c7
