glusterd/tier: remove tier related code from glusterd

2019-05-27T07:50:24+00:00

The handler functions are pointed to dummy functions.
The switch case handling for tier also have been moved to
point default case to avoid issues, if reintroduced.

The tier changes in DHT still remain as such.

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

glusterd: perform rcu_read_lock/unlock() under cleanup_lock mutex

2018-12-03T17:03:57+00:00

Problem: glusterd should not try to acquire locks on any resources,
when it already received a SIGTERM and cleanup is started. Otherwise
we might hit segfault, since the thread which is going through
cleanup path will be freeing up the resouces and some other thread
might be trying to acquire locks on freed resources.

Solution: perform rcu_read_lock/unlock() under cleanup_lock mutex.

Some (mgmt) xlators: use dict_{setn|getn|deln|get_int32n|set_int32n|set_strn}

2018-09-09T01:53:59+00:00

In a previous patch (https://review.gluster.org/20769) we've
added the key length to be passed to dict_* funcs, to remove the need
to strlen() it. This patch moves some xlators to use it.

- It also adds dict_get_int32n which was missing.
- It also reduces the size of some key variables.
They were set to 1024b or PATH_MAX, where sometimes 64 bytes were
really enough.

Please review carefully:
1. That I did not reduce some the size of the key variables too much.
2. That I did not mix up some keys.

Compile-tested only!

Move to GF_MALLOC() instead of GF_CALLOC() when possible

It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.

In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.

1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.

Only compile-tested!

.. and allocate memory as much as needed.

xlators/nfs/server/src/mount3.c :

Don't blindly allocate PATH_MAX, but strlen() the string and allocate
appropriately.
Also, align error messges.
