Builtin and extension modules are now initialized in a multi-phase process, which is similar to how Python modules are loaded. (See PEP 489 overview.) 标准库中的重大改进: collections.OrderedDict is now implemented in C, which makes it 4 to 100 times faster. The ssl module gained support ...
为connect/handle()、 enable_load_extension() 和load_extension() 加入审计事件。(由 Erlend E. Aasland 贡献于 bpo-43762) sys 加入了 sys.orig_argv 属性:传给 Python 可执行文件的初始命令行参数列表。(由 Victor Stinner 贡献于 bpo-23427) 添加了 sys.stdlib_module_names,包含标准库模块名称的列表。
connector = C:\Program Files (x86)\MySQL\MySQL Connector C 6.0.2 然后注意到了,上面的编译过程中的include的路径,就是此处的connector的值。 7.又在这里: Unofficial Windows Binaries for Python Extension Packages 找到了一个已编译的版本的下载地址: ...
gcc -g -shared ext/misc/json1.c -I. -I./src -o json1.dll 就生成了json1的插件了 要使用的话 再在python里执行 conn=sqlite3.connect(":memory:")conn.enable_load_extension(True)conn.load_extension("./json1.dll") 2021-03-21更新 插入了b站新支持的代码块 ...
Transitions includes an extension module which allows nesting states. This allows us to create contexts and to model cases where states are related to certain subtasks in the state machine. To create a nested state, either import NestedState from transitions or use a dictionary with the ...
我们看到在超时回调里 V8 分配了一个 ArrayBufferExtension 对象并记录到 ArrayBufferSweeper 中。 接着看一下触发 GC 时的逻辑。 V8 在 GC 中会调用 heap_->array_buffer_sweeper()->RequestSweepYoung() 回收堆外内存,另外 Node.js 本身似乎也使用线程去回收 堆外内存。我们再看一下自己管理内存的情况下回调...

This threadsafe callback request mechanism may also be used to delegate publishing of messages, etc., from a background thread to the connection adapter's thread. Connection recovery Some RabbitMQ clients (Bunny, Java, .NET, Objective-C, Swift) provide a way to automatically recover connection,...
