*.pc: Fix include path in Cflags

2017-11-08T11:10:44+00:00

The include path in glusterfs-api.pc looks like

  -I${includedir}/glusterfs

However, client code will include the glusterfs headers using

  #include 

rather than

  #include 

which makes the "/glusterfs" part entirely unnecessary.

More importantly, on some platforms such as FreeBSD, the header files
for glusterfs will be installed in /usr/local/include, which is *not*
part of the compiler's default include path, so compilation will fail
with something like

  fatal error: 'glusterfs/api/glfs.h' file not found
  #include 
           ^~~~~~~~~~~~~~~~~~~~~~

The fix is to simply drop the extra "/glusterfs". The same change
is applied to other *.pc files as well, althought I haven't actually
tested those.

A test program (gfapi-load-volfile) and the glfsxmp example
application were using the wrong include paths, so they had to be
fixed as well.

build: make contrib/uuid dependency optional

2015-04-10T11:39:52+00:00

On Linux systems we should use the libuuid from the distribution and not
bundle and statically link the contrib/uuid/ bits.

libglusterfs/src/compat-uuid.h has been introduced and should become an
abstraction layer for different UUID APIs. Non-Linux operating systems
should implement their compatibility layer there.

Once all operating systems have an implementation in compat-uuid.h, we
can remove contrib/uuid/ from the repository completely.

Adding Libgfdb to GlusterFS

2015-03-18T17:36:42+00:00

*************************************************************************
			Libgfdb						|
*************************************************************************
Libgfdb provides abstract mechanism to record extra/rich metadata
required for data maintenance, such as data tiering/classification.
It provides consumer with API for recording and querying, keeping
the consumer abstracted from the data store used beneath for storing data.
It works in a plug-and-play model, where data stores can be plugged-in.
Presently we have plugin for Sqlite3. In the future will provide recording
and querying performance optimizer. In the current implementation the schema
of metadata is fixed.

Schema:
~~~~~~
      GF_FILE_TB Table:
      ~~~~~~~~~~~~~~~~~
      This table has one entry per file inode. It holds the metadata required to
      make decisions in data maintenance.
      GF_ID (Primary key)	: File GFID (Universal Unique IDentifier in the namespace)
      W_SEC, W_MSEC 		: Write wind time in sec & micro-sec
      UW_SEC, UW_MSEC		: Write un-wind time in sec & micro-sec
      W_READ_SEC, W_READ_MSEC 	: Read wind time in sec & micro-sec
      UW_READ_SEC, UW_READ_MSEC : Read un-wind time in sec & micro-sec
      WRITE_FREQ_CNTR INTEGER	: Write Frequency Counter
      READ_FREQ_CNTR INTEGER	: Read Frequency Counter

      GF_FLINK_TABLE:
      ~~~~~~~~~~~~~~
      This table has all the hardlinks to a file inode.
      GF_ID		: File GFID               (Composite Primary Key)``|
      GF_PID		: Parent Directory GFID  (Composite Primary Key)   |-> Primary Key
      FNAME 		: File Base Name          (Composite Primary Key)__|
      FPATH 		: File Full Path (Its redundant for now, this will go)
      W_DEL_FLAG 	: This Flag is used for crash consistancy, when a link is unlinked.
                  	  i.e Set to 1 during unlink wind and during unwind this record
                          is deleted
      LINK_UPDATE 	: This Flag is used when a link is changed i.e rename.
                          Set to 1 when rename wind and set to 0 in rename unwind
