* 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.

* gfapi: Offload callback notifications to synctaskSoumya Koduri2018-11-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | Upcall notifications are received from server via epoll and same thread is used to forward these notifications to the application. This may lead to deadlock and hang in the following scenario. Consider if as part of handling these callbacks, application has to do some operations which involve sending I/Os to gfapi stack which inturn have to wait for epoll threads to receive repsonse. Thus this may lead to deadlock if all the epoll threads are waiting to complete these callback notifications. To address it, instead of using epoll thread itself, make use of synctask to send those notificaitons to the application.

* libgfapi: Add new api for supporting mandatory-locksAnoop C S2018-01-221-1/+3
| | | | | | | | | | | | | | | | The current API for byte-range locks [glfs_posix_lock()] doesn't allow applications to specify whether it is advisory or mandatory type locks. This particular change is to introduce an extended byte-range lock API with an additional argument for including the byte-range lock mode to be one among advisory(default) or mandatory. Patch also includes a gfapi test case which make use of this new api to acquire mandatory locks.

* gfapi/handleops: Introducing glfs_xreaddirplus_r() fop for handleopsSoumya Koduri2017-05-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Its known that readdirplus operation fetches stat as well for each of the dirents. But often applications may need extra information, like for eg., NFS-Ganesha which operates on handles needs handles for each of those dirents returned. So this would require extra calls to the backend, in this case LOOKUP (which is very expensive operation) resulting in very low readdir performance. To address that introducing this new API using which applications can make request for any extra information to be returned as part of readdirplus response. Currently this new api returns stat and handles as demanded by application. The synopsis of the API is noted in glfs.h. @todo: * Enhance test script using this new API Below were the perf results on single brick volume with and without these changes - Dataset used - 10*100 directories and each directory containing 100 empty files. I used NFS-Ganesha application to test these changes - >for i in {1..5}; do systemctl restart nfs-ganesha; sleep 10; mount -t nfs -o vers=4 localhost:/brick_vol /mnt; cd /mnt; echo "ITERATION$i"; date; find . > tmp-nfs.log; date; cd /; umount /mnt; sleep 2; done; Without these changes - ITERATION1 Mon Mar 20 17:22:26 IST 2017 Mon Mar 20 17:23:18 IST 2017 ITERATION2 Mon Mar 20 17:23:39 IST 2017 Mon Mar 20 17:24:28 IST 2017 ITERATION3 Mon Mar 20 17:24:49 IST 2017 Mon Mar 20 17:25:36 IST 2017 ITERATION4 Mon Mar 20 17:30:57 IST 2017 Mon Mar 20 17:31:37 IST 2017 ITERATION5 Mon Mar 20 17:31:57 IST 2017 Mon Mar 20 17:32:40 IST 2017 [root@dhcp35-197 /]# On an average ~46.2 sec With these changes applied - ITERATION1 Mon Mar 20 17:35:03 IST 2017 Mon Mar 20 17:35:15 IST 2017 ITERATION2 Mon Mar 20 17:35:36 IST 2017 Mon Mar 20 17:35:46 IST 2017 ITERATION3 Mon Mar 20 17:36:06 IST 2017 Mon Mar 20 17:36:17 IST 2017 ITERATION4 Mon Mar 20 17:41:38 IST 2017 Mon Mar 20 17:41:49 IST 2017 ITERATION5 Mon Mar 20 17:42:10 IST 2017 Mon Mar 20 17:42:20 IST 2017 On an average ~10.8 sec Updates #174 BUG: 1442950 Change-Id: I0f74f74dc62085ca4c4a23c38e3edc84bd850876 Signed-off-by: Soumya Koduri <skoduri@redhat.com> Reviewed-on: https://review.gluster.org/15663 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

* gfapi: add API to trigger events for debugging and troubleshootingNiels de Vos2017-01-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce glfs_sysrq() as a generic API for triggering debug and troubleshoot events. This interface will be used by the feature to get statedumps for applications using libgfapi. The current events that can be requested through this API are: - 'h'elp: log a mesage with all supported events - 's'tatedump: trigger a statedump for the passed glfs_t In future, this API can be used by a CLI to trigger statedumps from storage servers. At the moment it is limited to take statedumps, but it is extensible to set the log-level, clear caches, force reconnects and much more.
