* libglusterfs: pass buffer size to gf_store_read_and_tokenize functionGaurav Kumar Garg2016-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is backport of: http://review.gluster.org/#/c/12346/ Previously if user set an option where length of key=value goes beyond PATH_MAX (4096) character then tokenzing the option at the time of reading configuration file will fail. This is because of the we was having restraction in fgets to read maximum of PATH_MAX (4096) length of character. Consequence of this is when user try to restart glusterd, after setting key=value length beyond PATH_MAX (4096) character, glusterd will not restart. With this fix instead of PATH_MAX, consumer of gf_store_read_and_tokenize function will decide the size of the buffer length.

* nfs: make it possible to disable nfs.mount-rmtabNiels de Vos2015-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are many NFS-clients doing very often mount/unmount actions, the updating of the 'rmtab' can become a bottleneck and cause delays. In these situations, the output of 'showmount' may be less important than the responsiveness of the (un)mounting. By setting 'nfs.mount-rmtab' to the value "/-", the cache file is not updated anymore, and the entries are only kept in memory.

* mgmt/gluster: Use fsync instead of O_SYNCPranith Kumar K2014-05-051-0/+1
| | | | | | | | | | | | | | | | | Glusterd uses O_SYNC to write to temp file then performs renames to the actual file and performs fsync on parent directory. Until this rename happens syncing writes to the file can be deferred. In this patch O_SYNC open of temp file is removed and fsync of the fd before rename is done.

* store: Add (un)locking functionalityNiels de Vos2013-08-021-0/+10
| | | | | | | | | | | | | | | | | | | | | Some configuration/cache files (like the NFS rmtab) can be stored on a GlusterFS volume and be used by multiple storage servers. This requires suitable locking for the gf_store_handle_t structure. Introduce gf_store_lock() and gf_store_unlock() for this purpose. The gf_store_locked_local() function can be used to check if the gf_store_handle_t has been locked by the current process. This change also includes an unrelated correction where a FILE* was getting leaked. Krishnan Parthasarathi identified this while reviewing the new locking functionality.
