multiple xlators: reduce key length

2020-01-14T17:11:22+00:00

In many cases, we were freely allocating long keys with no need.
Smaller char arrays are just fine almost anywhere, so just went ahead
and looked where they we can use smaller ones.

In some cases, annotated the functions as static and the prefixes
passed as const as it was easier to read and understand.

Where relevant, converted the dict functions to use known key length.

mgmt/brick-mux: Avoid sending two response when attach is failed.

2019-12-31T13:35:10+00:00

We were sending two response back to glusterd when an attach is
failed. One from the handler function glusterfs_handle_attach and
another from rpcsvc_check_and_reply_error. It was causing problems
like ref leaks, transport disconnect etc.

[RFC]#ifdef gNFS related code if we are not compiling gNFS

2019-12-18T03:47:42+00:00

If we are not compiling gNFS (--enable-gnfs is not given in the
./configure script params), there is little point in compiling code
that is related to it.

This patch tries to eliminate it.
My hope (and it's not clear from the code ) is that I did not break
the NFS Ganesha support as well.

Other than that, tried to compile with and without anad it looks sane.

glusterfsd.c: remove sys_lstat() call

2019-11-27T07:21:10+00:00

get_volfp() in glfs.c doesn't use it, so get_volfp() in glusterfsd.c
can just open the file without the stat call as well, IMHO.

glusterfsd-mgmt.c: move INFO log outside a LOCK

2019-11-19T10:03:28+00:00

In glusterfs_handle_attach() we can:
1. Move an INFO level to be executed before the LOCK.
2. Skip the LOCK altogether, if there's no active graph.

I hope it's safe - I've seen that in other functions
you could look at ctx->active outside of a lock.
