performance/io-cache: update pages with write data

2018-12-18T09:19:16+00:00

Currently io-cache invalidate pages falling in the range of write. But
instead it can update pages with same data so that reads can make use
of the cache.

New xlator option to control enable/disable of xlators in Gd2

2018-12-07T05:28:23+00:00

Since glusterd2 don't maintain the xlator option details in code, it
directly reads the xlators options table from `*.so` files. To support
enable and disable of xlator new option added to the option table with
the name same as xlator name itself.

This change will not affect the functionality with glusterd1.

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.

all: fix the format string exceptions

2018-11-05T18:50:59+00:00

Currently, there are possibilities in few places, where a user-controlled
(like filename, program parameter etc) string can be passed as 'fmt' for
printf(), which can lead to segfault, if the user's string contains '%s',
'%d' in it.

While fixing it, makes sense to make the explicit check for such issues
across the codebase, by making the format call properly.

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!

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.
