Hi All,
This is my first post in the dev list :)
I wrote a methods to be triggered during release callback and added it
to xlator_cbks struct in trace.c but this method is not invoked at
all.
I can see that some other performance xlators such as write-behind and
read-ahead have similar callback handlers over release but but don't
know why my method is not called.
Is there any other config required besides setting release variable in
xlator_cbks struct to my function pointer?
I tried to set two others (releasedir and forget) but they are not
called either. I suppose editing a file in vim should call release at
the end. BTW my case is very similar to this issue in FUSE (
http://www.nabble.com/No-release-callback-after-cp-td23050110.html )
but I don't think there is any need for such a config in Gluster.
You need to set some context related to trace in fd->ctx. Only xlators who have stored their contexts in fd, will have their cbks called. You can set context in fd from trace as,
fd_ctx_set (this, fd, 1);
Generally last argument will be a pointer to structure holding context of the translator. Here its just a dummy value.
Thanks for your help,
