The simplest way to manipulate the GIL in Python C extensions is to use the macros provided: my_awesome_C_function() { blah; Py_BEGIN_ALLOW_THREADS // do stuff that doesn't need the GIL if (should_i_call_back) { Py_BLOCK_THREADS // do stuff that needs the GIL Py_UNBLOCK_THREADS } Py_END_ALLOW_THREADS return blah blah; } This works great,
在Python C扩展中操纵GIL的最简单方法是使用提供的宏： my_awesome_C_function() { blah; Py_BEGIN_ALLOW_THREADS // do stuff that doesn't need the GIL if (should_i_call_back) { Py_BLOCK_THREADS // do stuff that needs the GIL Py_UNBLOCK_THREADS } Py_END_ALLOW_THREADS return blah blah; } 这很好，让我释放大部分代码中的GIL，但重新获取需要它的小部
I have many inter-dependant Java projects kept inside a folder named 'Source'. Each project has build.xml also. I need to run all build.xml one by one from python. I was trying the following: import subprocess import os def callBuild(str, counter): proc = subprocess.check_output(["start", "cmd", "/k", "ant -v -d -f "+str], shell=True) return path = 'D:/ar/Source' for subdir
我有许多相互依赖的Java项目保存在名为“Source”的文件夹中。 每个项目也有build.xml。 我需要从python一个接一个地运行所有的build.xml。 我正在尝试以下内容： import subprocess import os def callBuild(str, counter): proc = subprocess.check_output(["start", "cmd", "/k", "ant -v -d -f "+str], shell=True) return path = 'D:/ar/Source' for subdir, dirs, files in os.walk(path): for file in fi
I am aware of the die() command in PHP which stops a script early. How can I do this in Python? import sys sys.exit() details from the sys module documentation: sys. exit ([arg]) Exit from Python. This is implemented by raising the SystemExit exception, so cleanup actions specified by finally clauses of try statements are honored, and it is possible to intercept the exit attempt at an ou
我知道PHP中的die()命令可以尽早停止脚本。 我怎样才能在Python中做到这一点？ import sys sys.exit() 来自sys模块文档的详细信息： sys. exit ([arg]) 从Python退出。 这是通过引发SystemExit异常实现的，所以try语句的finally子句指定的清理操作得到遵守，并且可以在外层拦截退出尝试。 可选参数arg可以是一个给出退出状态的整数（默认为零）或其他类型的对象。 如果它是一个整数，零被认为是“成功终止”，并且任何
I have the following situation in my python code: class Parent(object): def run(self): print "preparing for run" self.runImpl() print "run done" class Child(Parent): def runImpl(self): print "child running" However, I have several such 'decorators', doing different setup/teardown steps before and after 'runImpl', and I don't like havi
我的python代码中有以下情况： class Parent(object): def run(self): print "preparing for run" self.runImpl() print "run done" class Child(Parent): def runImpl(self): print "child running" 然而，我有几个这样的“装饰器”，在'runImpl'之前和之后进行不同的设置/拆卸步骤，我不喜欢定义run() ， runImpl() ， runImplSingleProcess()等。 我正在寻找以下形式的解
totally confused by now... I am developing in python/django and using python logging. All of my app requires unicode and all my models have only a unicode ()`, return u'..' methods implemented. Now when logging I have come upon a really strange issue that it took a long time to discover that I could reproduce it. I have tried both Py 2.5.5 and Py 2.6.4 and same thing. So Whenever I
现在完全混淆了......我正在开发python / django并使用python日志记录。 我所有的应用程序都需要unicode，我的所有模型都只有一个unicode （）`，return u'..'方法。 现在当我记录时，我遇到了一个很奇怪的问题，那就是花了很长时间才发现我可以重现它。 我已经尝试了Py 2.5.5和Py 2.6.4以及同样的东西。 所以 每当我做一些简单的日志记录就像： logging.debug(u'new value %s' % group) 这称为模型组。 unico
I want to write python bindings to ac library using cython. The library represents a multithreaded http server and exposes it's API via a header file. Following the cython guide, I wrote a pxd and a pyc file, containing definitions for 3 basic functions: struct server *server_init() int server_start(struct server *) int server_stop(struct server *) The python wrappers looks similar to: c
我想用cython编写python绑定到ac库。 该库表示一个多线程的http服务器，并通过头文件公开它的API。 遵循cython指南，我写了一个pxd和pyc文件，其中包含3个基本函数的定义： struct server *server_init() int server_start(struct server *) int server_stop(struct server *) python包装看起来类似于： cdef class Server: cdef library.server *_server def __cinit__(self): self._server = library.ser
I'm fairly new to lxml and HTML Parsers as a whole. I was wondering if there is a way to replace an element within a tree with another element... For example I have: body = """<code> def function(arg): print arg </code> Blah blah blah <code> int main() { return 0; } </code> """ doc = lxml.html.fromstring(body) codeblocks = doc.cssselect('code') for block in codeb
作为一个整体，我对lxml和HTML Parsers相当陌生。 我想知道是否有方法用另一个元素替换树中的元素... 例如，我有： body = """<code> def function(arg): print arg </code> Blah blah blah <code> int main() { return 0; } </code> """ doc = lxml.html.fromstring(body) codeblocks = doc.cssselect('code') for block in codeblocks: lexer = guess_lexer(block.text_content()) hilited =
In python setuptools, python setup.py test runs the testsuite. However if I have an import error in my testsuite, the only error message I obtain is an AttributeError complaining that my test class is missing. Is there a way to obtain a more detailed error message, so I can fix the testsuite ? I will explain myself better with the following example. Suppose I have a package called foo, creat
在python setuptools中，python setup.py测试运行测试套件。 但是，如果我的测试套件中存在导入错误，则我得到的唯一错误消息是一个AttributeError，它抱怨我的测试类缺失。 有没有办法获得更详细的错误信息，所以我可以修复测试套件？ 下面的例子我会更好地解释自己。 假设我有一个名为foo的包，用paster重新创建。 然后我添加测试 ./foo ./foo/__init__.py ./foo/tests ./foo/tests/__init__.py ./foo/tests/mytest.py .
We're considering re-factoring a large application with a complex GUI which is isolated in a decoupled fashion from the back-end, to use the new (Python 2.6) multiprocessing module. The GUI/backend interface uses Queues with Message objects exchanged in both directions. One thing I've just concluded (tentatively, but feel free to confirm it) is that "object identity" would no
我们正在考虑重新构建一个大型应用程序，使用复杂的GUI，并以与后端分离的方式隔离，以使用新的（Python 2.6）多处理模块。 GUI /后端接口使用两个方向交换消息对象的队列。 我刚刚总结的一件事（暂时性的，但可以自由地确认它）是在多处理接口中不会保留“对象标识”。 目前，当我们的GUI向后端发布消息时，它期望获得相同的消息并将结果附加为属性。 它使用对象标识（ if received_msg is message_i_sent:以在某些情况下标
I want to dynamically update the scatter plot based on the y-axis data received from a socket connection. I used python matplot lib in interactive mode to do this, but during dynamic updation if i move the window to a different location or minimize the window then the plot updation stops abruptly. How to do this? I have attached a sample dynamic updation code used here and the same problem ap
我想根据从套接字连接接收到的Y轴数据动态更新散点图。 我在交互模式下使用python matplot lib来做到这一点，但是在动态更新期间，如果我将窗口移动到不同的位置或最小化窗口，那么绘图更新会突然停止。 这个怎么做？ 我附上了这里使用的示例动态更新代码，同样的问题也出现在这里。 import matplotlib.pyplot as plt import random import time items = [25.5,26.7,23.4,22.5,20,13.4,15.6,-12,-16,20] x = [1,2,3,4,5,6,7,
