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.

io-cache: xdata needs to be passed for readv operations

2018-12-04T05:23:03+00:00

io-cache xlator has been skipping xdata references when the
date needs to be read into page cache. This patch fixes the same.

Note: similar changes may be needed for other fops as well
which are handled by io-cache.

Multiple xlators: perform gettimeofday() not under lock

2018-10-16T06:33:29+00:00

While it may slightly reduce accuracy, I think it's better to
acquire the time outside a lock and then memcpy the value while
under lock.

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.

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.
