Introduce pthread_condattr_setclock() This is one of the few POSIX APIs that was missing. It lets you choose a monotonic clock for your condition variables. This might improve perf on some platforms. It might also grant more flexibility with NTP configs. I know Qt is one project that believes it needs this. To introduce this, I needed to change some the *NSYNC APIs, to support passing a clock param. There's also new benchmarks, demonstrating Cosmopolitan's supremacy over many libc implementations when it comes to mutex performance. Cygwin has an alarmingly bad pthread_mutex_t implementation. It is so bad that they would have been significantly better off if they'd used naive spinlocks.

COSMOPOLITAN_C_END_
Improve Libc by making Python work even better Actually Portable Python is now outperforming the Python binaries that come bundled with Linux distros, at things like HTTP serving. You can now have a fully featured Python install in just one .com file that runs on six operating systems and is about 10mb in size. With tuning, the tiniest is ~1mb. We've got most of the libraries working, including pysqlite, and the repl now feels very pleasant. The things you can't do quite yet are: threads and shared objects but that can happen in the future, if the community falls in love with this project and wants to see it developed further. Changes: - Add siginterrupt() - Add sqlite3 to Python - Add issymlink() helper - Make GetZipCdir() faster - Add tgamma() and finite() - Add legacy function lutimes() - Add readlink() and realpath() - Use heap allocations when appropriate - Reorganize Python into two-stage build - Save Lua / Python shell history to dotfile - Integrate Python Lib embedding into linkage - Make isregularfile() and isdirectory() go faster - Make Python shell auto-completion work perfectly - Make crash reports work better if changed directory - Fix Python+NT open() / access() flag overflow error - Disable Python tests relating to \N{LONG NAME} syntax - Have Python REPL copyright() show all notice embeddings The biggest technical challenge at the moment is working around when Python tries to be too clever about filenames.

Graduate some clock_gettime() constants to #define - CLOCK_THREAD_CPUTIME_ID - CLOCK_PROCESS_CPUTIME_ID Cosmo now supports the above constants universally across supported OSes therefore it's now safe to let programs detect their presence w/ #ifdefs
