Multiple files: reduce work while under lock.

2019-01-29T09:27:22+00:00

Mostly, unlock before logging.
In some cases, moved different code that was not needed
to be under lock (for example, taking time, or malloc'ing)
to be executed before taking the lock.

Note: logging might be slightly less accurate in order, since it may
not be done now under the lock, so order of logs is racy. I think
it's a reasonable compromise.

Compile-tested only!

all: handle USE_AFTER_FREE warnings

2018-12-20T06:26:37+00:00

* we shouldn't be using 'local' after DHT_STACK_UNWIND() as it frees
the content of local. Add a 'goto out' or similar logic to handle
the situation.

* fix possible overlook of unref(dict), instead of unref(xdata).

* make coverity happy by re-ordering unref in meta-defaults.

* gfid-access: re-order dictionary allocation so we don't have to
  do a extra unref.

* other obvious errors reported.

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.

all: fix warnings on non 64-bits architectures

2018-10-10T05:50:29+00:00

When compiling in other architectures there appear many warnings. Some
of them are actual problems that prevent gluster to work correctly on
those architectures.

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.
