globals

问题 I would like to clarify, how globals from different modules are scoped? I failed to find relevant documentation for this matter, thus I am relying on observation, but I would like to have some more insight, if my findings are pure implementation coincidence, or if I can trust them? Testcase: module_1.py: global_var1 = 'm1_v1' global_var2 = 'm1_v2' def f(): print('f: {}'.format(global_var1)) print('f: {}'.format(global_var2)) module_2.py: import module_1 global_var1 = 'm2_v1' def g(): print('g

问题 I am learning and exploring applications of PHPUnit with PHP 5.2.9 and have run into the globals issue. I have set $backupGlobals to FALSE, included the doc '@backupGlobals disabled' and this doesn't seem to affect the behaviour of PHPUnit's backing up of the globals. Is there something I'm missing? Do I need to alter PHPUnit's xml file? Create a bootstrap? config.php: $testString = 'Hello world!'; basicApp.php: require ('D:\data\clients\security.ca\web_sites\QRASystems.com\wwwroot\__tests

问题 How do i detect or capture change of value of a global variable in python variable = 10 print(variable) variable = 20 # Detect changes to the value using a signal to trigger a function UPDATE AST docs - GOOD INTRO https://greentreesnakes.readthedocs.io/en/latest/ 回答1: To my knowledge, it is not possible to generically capture the assignment of a global symbol in Python (At least in CPython where globals are stored in a dict in the module object, both are C types that cannot be monkey patched)

问题 From the DailyJS "Let's build a JavaScript Framework" I'm not quite sure on the following code, obviously used as a global abatement technique. My understanding so far balks at (function(){}) . I understand setting the turing var up, setting global.turing to turing, and return either window or this (if not in a browser), but the (function(global){})(this or window) thing confuses me...I've seen things like var mything = {} and setting all your code up under mything, but this idiom confuses me

问题 When declaring and using global variables within Drools, are globals entirely bound to the session in the sense that once the session is closed, the globals are disposed of too? Is there some way of storing data in drools memory that can be accessed by numerous sessions at any one time without needing it to be reloaded each time? 回答1: A DRL global is a POJO, which exists as long as there exists at least one reference to it. After setGlobal, a session keeps one (additional) reference, which is
