* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* arbiter: return ENOSYS for 'non readable' FOPsNiels de Vos2017-09-051-10/+35
| | | | | | | | | | | | | | | | AFR marks the arbiter as 'non readable'. This has been introduced with commit 8ab87137 (afr: do not set arbiter as a readable subvol in inode context). arbiter_readv() should not get called anymore, so it could be removed. However, it is a good defensive approach to have all the inode read FOPs that can not be handled by the arbiter to return ENOSYS.

* arbiter: Fix memleak in arbiter_inode ctxRavishankar N2016-08-231-25/+11
| | | | | | | | | | | | | | | | | | | | | Problem: The iattbuf ptr stored in arbiter's inode context was not freed during inode forget. Fix: Change it to a statically allocated value so that we don't have to deal with allocating/freeing it.

* arbiter: write performance improvementRavishankar N2016-04-111-8/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The throughput for a 'dd' workload was much less for arbiter configuration when compared to normal replica-3 volume. There were 2 issues: i)arbiter_writev was using the request dict as response dict while unwinding, leading to incorect GLUSTERFS_WRITE_IS_APPEND and GLUSTERFS_OPEN_FD_COUNT values (=4), leading to immediate post-ops because is_afr_delayed_changelog_post_op_needed() failed due to afr_are_multiple_fds_opened() check. ii) The arbiter code in afr was setting local->transaction.{start and len} =0 to take full file locks. What this meant was even for simultaenous but non-overlapping writevs, afr_transaction_eager_lock_init() was not happening because afr_locals_overlap() always stays true. Consequently is_afr_delayed_changelog_post_op_needed() failed due to local->delayed_post_op not being set. Fix: i) Send appropriate response dict values in arbiter_writev. ii) Modify flock params instead of local->transaction.{start and len} to take full file locks in the transaction. Also changed _fill_writev_xdata() in posix to fill rsp_xdata for whatever key is requested for.

* build: do not #include "config.h" in each fileNiels de Vos2015-05-291-5/+0
| | | | | | | | | | | | | | | | | | 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.

* afr: arbiter xlatorRavishankar N2015-03-191-0/+324
This patch adds the arbiter translator into the tree. This is a server side xlator used for replica 3 volumes. It sits above posix and will be loaded on the 3rd (last) brick of every afr subvolume in a replica 3 configuration. It intercepts inode read/write operations: reads are unwound with ENOTCONN, inode writes are unwound with success without actually passing them down to posix. Metadata operations are allowed to pass through. The CLI for creating a 3 way replica with arbiter is also added but kept disabled (A 'normal' 3 way replica is created instead). This patch is a part of the arbiter logic implementation for 3 way AFR, details of which can be found at http://review.gluster.org/#/c/9656/ Change-Id: I395b81f49d5da52c466daf5c8518f1bbad9c16fa BUG: 1199985 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/9840 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
