* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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. Change-Id: Id2a98854e671a7ee5d73be44da5ba1a74252423b Updates: bz#1193929 Signed-off-by: ShyamsundarR <>

* features/compress: Compression/DeCompression translatorPrashanth Pai2013-11-111-0/+107
* When a writev call occurs, the client compresses the data before sending it to server. On the server, compressed data is decompressed. Similarly, when a readv call occurs, the server compresses the data before sending it to client. On the client, the compressed data is decompressed. Thus the amount of data sent over the wire is minimized. * Compression/Decompression is done using Zlib library. * During normal operation, this is the format of data sent over wire : <compressed-data> + trailer(8) The trailer contains the CRC32 checksum and length of original uncompressed data. This is used for validation.
