Hi, I m using the project to do mysql binlog to redis thing. but in some cases, my cpu goes up to 100% and the sync process seems to hang. i did some digging and found the stack always stop at Program received signal SIGINT, Interrupt. 0x00007fe57a06e698 in __memcpy_ssse3_back ...
The line signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM) is the line to determine which signals the application should respond with. For testing purposes, we would set it up such that it would be able to respond and capture for the Termination signal as well Interrupt signal. SIGTERM mig...
When killing the program in gdb, and runningbacktrace full, I get: Thread1"findpng2"received signal SIGINT, Interrupt.0x00007ffff757cd2din __GI___pthread_timedjoin_ex (threadid=140737201288960, thread_return=0x0, abstime=0x0, block=<optimized out>) at pthread_join_common.c:8989pthread_jo...
Have you ever thought of what goes behind this. Well, whenever ctrl+c is pressed, a signal SIGINT is sent to the process. The default action of this signal is to terminate the process. But this signal can also be handled. The following code demonstrates this : #include<stdio.h> #includ...

Sending a Signal to a Program Thedbxcontcommand supports the-sigsignaloption, which lets you resume execution of a program with the program behaving as if it had received the system signalsignal. For example, if a program has an interrupt handler forSIGINT(^C), you can type^Cto stop the ...
trap {your handler script here} SIGINT You might want to make the handler script (which can be a multi-line thing) send the signal on to the inner process… trap { send \x03 send_user "You pressed Ctrl+C\n" } SIGINT But take care! When the user presses Ctrl+C in a text-mode...

Check out line 8—we tell the program to ignore SIGINT, the interrupt signal that’s raised when CTRL-C is hit. No matter how much you hit it, the signal remains ignored. If you comment out line 8, you’ll see you can CTRL-C with impunity and quit the program on the spot. ...
I can think of at least one very good reasons for doing this with the SIGINT signal. Namely implementing a signal handler that executes either a last ditch backup, saves a memory dump, or writes to log, before reverting to the default signal operation that terminates the...
