* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | xlators/features/changelog/lib/src/gf-changelog-journal-handler.c xlators/features/changelog/lib/src/gf-changelog.c xlators/features/changelog/src/changelog-helpers.c xlators/features/changelog/src/changelog-misc.h strncpy may not be very efficient for short strings copied into a large buffer: If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written. Instead, use snprintf(). Where possible, ensure there's no truncation of the output. Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN (sizeof() ) for const strings. - switch a strncpy to a memcpy. Compile-tested only!

* features/changelog: RPC'fy {libgf}changelogVenky Shankar2015-03-181-0/+985
This patch introduces RPC based communication between the changelog translator and libgfchangelog. It replaces the old pathetic stream based interaction that existed earlier (due to time constraints :-/). Changelog, upon initialization starts a RPC server (rpcsvc) allowing clients to invoke a probe API as a bootup mechanism to request for event notifications. During probe, clients can choose an event filter specifying the type(s) of events they are interested in. As of now there is no way to change the event notification set once the probe RPC call is made, but that is easier to implement. The actual event notifications is done on a separate RPC session. The client (libgfchangelog) itself starts and RPC server which the changelog translator "connects back" during probe. Notifications are dispatched by a bunch of threads from the server (translator) and the client optionally orders them if ordered notifications are requried. FOPs fill in their respective event details in a buffer (rot-buffs to be particular) and a bunch of threads (consumers) swap the buffers out of roatation and dispatch them via RPC. To avoid writer starvation, then number of dispatcher threads is one less than the number of buffer list in rot-buffs.x libgfchangelog becomes purely callback based -- upon event notification from the server (and re-ordering them if required) invoke a callback routine specified by consumer(s). A major part of the patch is also aimed at providing backward compatibility for geo-replication, which was one of the main consumer of the stream based API. Also, this patch does not\ "turn on" event notifications for all fops, just a bunch which is currently in requirement. Another pain point is that the server does not filter events before dispatching it to the clients. That load is taken up by the client itself (although it's done at the library layer rather than making it hard on the callback implementor). This needs improvement and care needs to be taken to not load the server up with expensive filtering mechanisms.
