qemu-block: deprecated/defunct, remove from tree

2016-03-07T11:34:59+00:00

qemu-block xlator is not used by anyone, or so I'm told.

It's also substantially out of date. There's little reason to keep
it in our sources. (And FedoraProject doesn't like bundled software
either.)

quota/marker: use smaller stacksize in synctask for marker updation

2015-07-10T06:54:23+00:00

Default stacksize that synctask uses is 2M.
For marker we set it to 16k

Also move market xlator close to io-threads
to have smaller stack

features/qemu-block: Don't unref root inode

2015-05-30T12:37:18+00:00

Root inode doesn't participate in ref/unref. Don't do it
in fini as by the time fini is called itable would be destroyed.

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.

libglusterfs/syncop: Add xdata to all syncop calls

2015-04-08T15:14:59+00:00

This patch adds support for xdata in both the
request and response path of syncops.

Few calls like lookup already had the support;
have renamed variables in few places to maintain
uniformity.

xdata passed downwards is known as xdata_in
and xdata passed upwards is known as xdata_out.

There is an old patch by Jeff Darcy at
http://review.gluster.org/#/c/8769/3 which does the
same for some selected calls. It also brings in
xdata support at gfapi level.

xdata support at gfapi level would be introduced
in subsequent patches.

Avoid conflict between contrib/uuid and system uuid

2015-04-04T17:48:35+00:00

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.

Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.

A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.

Do not assume sizeof(size_t)

2014-09-16T11:47:15+00:00

This fixes an assumption that sizeof(size_t) == sizeof(uint64_t), which
is not guaranteed. At least on NetBSD/i386, size_t is 32 bit long.
