Once I determined that it is the ADO.NET connection at the root of the problem, this thread led me to the answer. Basically connections through Sql Server Management Studio (SSMS) by default have SET ARITHABORT ON. ADO.NET connections do not. Setting ARITHABORT OFF and executing the query directly through SSMS gives me the same slow … Read more
There is a nice Perl script on CPAN to do just this: http://search.cpan.org/~rsoliv/mysql-genocide-0.03/mysql-genocide One only needs to schedule it to run with the proper parameters. Create a CRONtab file /etc/cron.d/mysql_query_timeout to schedule it to run every minute: * * * * * root /path/to/mysql-genocide -t 7200 -s -K Where 7200 is the maxiumum allowed execution … Read more
I suspect this is implementation-dependent. That said, for CPython: From socket.create_connection, If no timeout is supplied, the global default timeout setting returned by :func:getdefaulttimeout is used. From socketmodule.c, static PyObject * socket_getdefaulttimeout(PyObject *self) { if (defaulttimeout < 0.0) { Py_INCREF(Py_None); return Py_None; } else return PyFloat_FromDouble(defaulttimeout); } Earlier in the same file, static double defaulttimeout … Read more
I will try to answer it a little bit more informally. Connection timeout – is a time period within which a connection between a client and a server must be established. Suppose that you navigate your browser (client) to some website (server). What happens is that your browser starts to listen for a response message … Read more
You can simplify things a bit by putting command right in the test and doing increments a bit differently. Otherwise the script looks fine: NEXT_WAIT_TIME=0 until [ $NEXT_WAIT_TIME -eq 5 ] || command; do sleep $(( NEXT_WAIT_TIME++ )) done [ $NEXT_WAIT_TIME -lt 5 ]
Server is trying to read data from the request, but its taking longer than the timeout value for the data to arrive from the client. Timeout here would typically be tomcat connector -> connectionTimeout attribute. Correct. Client has a read timeout set, and server is taking longer than that to respond. No. That would cause … Read more
The following will keep looking for someVariable until it is found. It checks every 0.25 seconds. function waitForElement(){ if(typeof someVariable !== “undefined”){ //variable exists, do what you want } else{ setTimeout(waitForElement, 250); } }
I’ve searched a bit on this topic and came to conclusion that in some case (if you are using linux) you can use ‘timeout’ command. It’s pretty flexible Usage: timeout [OPTION] DURATION COMMAND [ARG]… or: timeout [OPTION] in my particular case I’m trying to run sphinx indexer from PHP, kinda migration data script so I … Read more
A thread can not gracefully kill another thread, so with your current code, foo never terminates. (With thread.daemon = True the Python program will exit when only daemon threads are left, but that does not allow you to terminate foo without also terminating the main thread.) Some people have tried to use signals to halt … Read more
You can do this efficiently using select from Ruby’s IO class. IO::select takes 4 parameters. The first three are arrays of sockets to monitor and the last one is a timeout (specified in seconds). The way select works is that it makes lists of IO objects ready for a given operation by blocking until at … Read more
