I am getting the following error calling watchDirectory for the following program. On mac osx mavericks. Any help is appreciated, thanks.
The log output
starting watch
CoreTaskFiber was terminated unexpectedly: Assertion failure
Here is the program
import vibe.d;
shared static this()
{
runTask({
logInfo("starting watch");
auto dw = watchDirectory("/Users/glen/_a/");
logInfo("watching");
});
}
Okay I admit I am a markdown newb. Here is the relevant info using properly formatted markdown
{
import vibe.d;
shared static this()
{
runTask({
logInfo("starting watch");
auto dw = watchDirectory("/Users/glen/_a/");
logInfo("watching");
});
}
}
The log output is
{
starting watch
CoreTaskFiber was terminated unexpectedly: Assertion failure
}

try to run you program with all logging enabled (i think --vvv) to get more info
Thanks, here is the output. Note I noticed the event loop hadn't started before the call to watchDirectory failed. So I added a sleep for 10 seconds before the failing call to watchDirectory. It still failed but now with a full stack trace.

The reason is that watchDirectory unfortunately isn't implemented yet
for the libevent driver. I've added a proper message to the assertion now.
I'll need this feature in the mid term, so if nobody beats me to it, it
will be scheduled for the next version (0.7.20).
Thanks for the quick response. That certainly explains the issue.
Also thanks for making this project possible. I am really excited at the possibilities to build first class async io based apps without having to play the deeply nested event handlers game.
