Dispatch Sources
I recently asked if anyone had suggestions concerning a seeming kqueue deadlock
in writing a OS X native java WatchService.
Someone, I think off-list, did suggest using VDKQueue[1], an updated version of
Uli Kusterer’s UKKQueue.
Looking at that the main difference seemed to be that is used GCD for the event
notification part.
As a quick test I changed my code to do this…
dispatch_async(dispatch_get_main_queue(),^{
[self
postJava:context about:FILE_MODIFIED withWatchKey:watchKey];
});
This didn’t seem to correct the problem.
I did notice that Dispatch Sources[2] seem to be a newer feature that is even
more GCD based.
I looked for examples of it’s use…
googling
DISPATCH_SOURCE_TYPE_VNODE filetype:m
There do appear to be examples for directories but as near as I’ve been able to
tell in quick scans of the source they only have an open file descriptor for
the directory and then sometimes seem to sweep the directory to determine what
has changed.
Is this correct? Is this the normal use for this code. You would not have open
fd’s for every file in the directory?
Does anyone know of any full fledged file monitors implemented with this that I
might of missed in my search? (open source)
Would my chances be decent that using this might avoid the deadlock issues I
was running into with kqueue?

Re: Uploading binary troubles?
Oh, I guess the magic is to first complain to the list, then try again. It finally worked. It's really flaky, though. > On Dec 10, 2016, at 02:06 , Rick Mann wrote: > > I've been having no end of problems trying to upload a new binary to Apple > today. Has anyone else?

Uploading binary troubles?
I've been having no end of problems trying to upload a new binary to Apple today. Has anyone else? Either I get complaints about my binary, which I addressed, or I get "This action could not be completed. Try again. (-22421)." I've gotten the try-again error six times today, in the afternoon, and now (about 2 am PST). Has anyone successfully uploaded a binary in the last 24 hours? -- Rick Mann rm...@latencyzero.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
