If you’re calling third-party code you can’t control, which catches BaseException, set this to a low number If your code traps a specific exception type, this will allow you #raiseEvery seconds to cleanup before exit. MyExceptionType not raiseEvery Default 2.0 - We will keep raising this exception every #raiseEvery seconds, This should be a class/type, NOT an instance, i.e. That inherits from BaseException (so except Exception as e: continue isn’t a problem) Stops the thread by raising a given exception - Exception to throw.

The StoppableThread class (you must extend this for your thread) adds a function, stop, which can be called to stop the thread.ĭef stop(self, exception, raiseEvery=2.0): This will allow you to call functions in stoppable threads, for example handlers in an event loop, which can be stopped later via the. MyThread = StoppableThread( target=myFunction, args=(‘ordered’, ‘args’, ‘here’), kwargs= ) stop( StopExceptionType ) to stop it ( more in “Stopping a Thread” belowĪlternatively, you can instantiate StoppableThread directly and pass the “target”, “args”, and “kwargs” arguments to the constructor Then, at any time during the thread’s execution, you can call. will terminate/join automatically upon main thread exit # Uncomment next line to start thread in “daemon mode” - i.e. Then, you can create and start this thread like: Your thread can extend func_ and implement the “run” method, same as a normal thread.įrom func_timeout.StoppableThread import StoppableThread You can use StoppableThread one of two ways: # Handle any exceptions that doit might raise here Print ( “doit(‘arg1’, ‘arg2’) could not complete within 5 seconds and was terminated.\n”) So, for esxample, if you have a function “doit(‘arg1’, ‘arg2’)” that you want to limit to running for 5 seconds, with func_timeout you can call it like this:įrom func_timeout import func_timeout, FunctionTimedOutĭoitReturnValue = func_timeout(5, doit, args=(‘arg1’, ‘arg2’)) Raises any exceptions #func# would raise, returns what #func# would return (unless timeout is exceeded), in which case it raises timeout - Maximum number of seconds to run #func# before func - The function to args - Any ordered arguments to pass to the kwargs - Keyword arguments to pass to the - FunctionTimedOut if #timeout# is exceeded, otherwise anything #func# could raise will be - The return value that #func# gives If Curl cannot establish a connection within the specified interval, the command fails.This is the function wherein you pass the timeout, the function you want to call, and any arguments, and it runs it for up to #timeout# seconds, and will return/raise anything the passed function would otherwise return or raise.ĭef func_timeout(timeout, func, args=(), kwargs=None):įunc_timeout - Runs the given function for up to #timeout# seconds.

The connection timeout value is specified in seconds. The –connect-timeout parameter limits the amount of time Curl will spend trying to connect to the remote host.

What is -connect-timeout and how to use it? To set a timeout for a Curl command, you can use the -connect-timeout parameter to set the maximum time in seconds that you allow Curl to connect to the server, or the -max-time (or -m) parameter for the total time in seconds that you authorize the whole operation. Curl has default timeouts for connection and total request time, but we can specify our timeouts for each Curl command. Establishing a connection with a remote server may take some time, depending on network speed, network latency, and server load. The first step in getting a resource from a server is to connect to that server. Curl sends requests works over a network connection. Curl works on all modern platforms like Windows, Linux, and macOS. Developers use Curl to test APIs, automate tasks, and support SSL certificates and HTTP Cookies. Curl supports all popular internet protocols, including HTTP and HTTPS.
