Python 的原生 multithreading 支援

在 Simon Willison 這邊看到的：「Real Multithreading is Coming to Python - Learn How You Can Use It Now」，他引用的原文在「Real Multithreading is Coming to Python - Learn How You Can Use It Now」這邊，在講 Python 3.12 將會有原生 multithreading 支援。

Python 裡知名的 GIL 問題將會用 Per-Interpreter GIL 的技術來解決，把 GIL 的 global-based 改寫變成 thread-based：

With introduction of "Per-Interpreter GIL", individual Python interpreters don't share the same GIL anymore. This level of isolation allows each of these sub-interpreters to run really concurrently.

這算是基礎建設，之後應該會有蠻長的陣痛期要轉換，尤其是各個其他程式語言寫的 library 要考慮到 thread-safe 的問題。

話說回來，PHP 就沒繼續討論過 threading 這個問題了，大家還是繼續用 process 架構在搞 XD

Multithreading 版本 pt-online-schema-change

看起來是個嘗試，Percona 的人試著修改 pt-online-schema-change，讓他可以在 INSERT 時 multi-threading，然後看效果：「Multithreaded ALTER TABLE with pt-online-schema-change and myloader」。 可以看出來 thread 夠多的情況下其實都變快不少 (上圖主要是看絕對數字，下圖是看相對比率)： 如果沒有意外的話應該會有更多的測試，而這些測試沒問題的話，之後的官方版本裡面應該就會有這個功能。

Google 弄出來的 Grumpy：把 Python 2.7 的程式碼轉成 Go...

Google 放出 Grumpy，可以把 Python 2.7 的程式碼轉成 Go：「Grumpy: Go running Python!」。 下面看到一個留言頗有趣的： This sad to see that Grumpy is mean to be a replacement of CPython 2.7 instead of CPython 3.x . I presume the code from youtube was written in python 2.x hence the reason but I hope we'll see…

HipHop for PHP 計畫

由 HipHop for PHP project 的幾位帶領者所說明的會議中解釋了不少東西 (在 USTREAM 有錄影可以觀看：Facebook Technology Tasting - HipHop for PHP)。 前半部份等於是把「HipHop for PHP: Move Fast」重講一次，並且說明他們在不少 case 下可以分析出 variable type，所以不需要用 zval (一般性的變數)。 比較重要的是後半段的 Q&A 部份。 就會場所提到的，他們目前跑在 Apache 1.3 + prefork 上面。有計劃要支援 multithreading，好處是 shared resource 可以共用，像是 database connection，但解法是苦工 (修正所有 thread-safe 的問題)。而既有的 extension (包括他們自己寫的) 則是維持相容，這應該是指維持 PHP extension 介面相容性。…
