Files, purpose, and dependencies.
-------------------------------------------------------------------------------
*----------------*
*- AIS INCLUDES -*
*----------------*
include/ais_amf.h
-----------------
Definitions for AMF interface.
include/ais_ckpt.h
------------------
Definitions for CKPT interface.
include/ais_clm.h
-----------------
Definitions for CLM interface.
include/ais_msg.h
-----------------
All the stuff that is used to specify how lib and executive communicate
including message identifiers, message request data, and mesage response
data.
include/ais_types.h
-------------------
Base type definitions for AIS interface.
include/list.h
-------------
Doubly linked list inline implementation.
include/queue.h
---------------
FIFO queue inline implementation.
depends on list.
include/sq.h
------------
Sort queue where items are sorted according to a sequence number. Avoids
Sort, hence, install of a new element takes is O(1). Inline implementation.
depends on list.
*---------------*
* AIS LIBRARIES *
*---------------*
lib/amf.c
---------
AMF user library linked into user application.
lib/ckpt.c
----------
CKPT user library linked into user application.
lib/clm.c
---------
CLM user library linked into user application.
lib/util.c
----------
Utility functions used by all libraries.
*-----------------*
*- AIS EXECUTIVE -*
*-----------------*
exec/amf.{h|c}
-------------
Server side implementation of Availability Management Framework (AMF API).
exec/ckpt.{h|c}
Server side implementation of Checkpointing (CKPT API).
exec/clm.{h|c}
Server side implementation of Cluster Membership (CLM API).
exec/gmi.{h|c}
--------------
group messaging interface supporting reliable totally ordered group multicast
using ring topology. Supports extended virtual synchrony delivery semantics
with strong membership guarantees.
depends on cglpoll.
depends on queue.
depends on sq.
depends on list.
exec/handlers.h
---------------
Functional specification of a service that connects into AIS executive.
If all functions are implemented, new services can easily be added.
exec/main.{h|c}
--------------
Main dispatch functionality and global data types used to connect AIS
services into one component.
exec/mempool.{h|c}
------------------
Memory pool implementation that supports preallocated memory blocks to
avoid OOM errors.
exec/parse.{h|c}
----------------
Parsing functions for parsing /etc/ais/groups.conf and
/etc/ais/network.conf into internally used data structures.
exec/poll.{h|c}
---------------
poll abstraction with support for nearly unlimited large poll handlers
and timer handlers.
depends on tlist.
exec/print.{h|c}
----------------
Logging implementation meant to replace syslog. syslog has nasty side
effect of causing a signal every time a message is logged.
exec/tlist.{h|c}
-----------------
Timer list interface for supporting timer addition, removal, expiry, and
determination of timeout period left for next timer to expire.
depends on list.
exec/log/print.{h|c}
--------------------
Prototype implementation of logging to syslog without using syslog C
library call.
loc
---
Counts the lines of code in the AIS implementation.
