|
- Current priority list for Needle 2.1
|
|
|
---------------------------------------
|
|
|
-* disallow binding to localhost (Honza)
|
|
|
-* don't rely on mcast loop (Honza)
|
|
|
-* Add support for LOG_TRACE and log received messages in this level (Honza)
|
|
|
-* Proper support for DNS (always return one address even if function
|
|
|
- is called multiple times) (Honza)
|
|
|
-* porting of qdisk to votequorum and eventually finalize qdevice API
|
|
|
- in votequorum. (Fabio)
|
|
|
-* Cleaner shutdown process -> free memory (Fabio)

- Current priority list for Needle 2.X
|
|
|
---------------------------------------
|
|
|
-* logsys glue layer removal
|
|
|
-* harden and finish ykd algorithm
|
|
|
-* implement topic-xmlschema
|
|
|
-* Modify totemsrp to allow dynamic definitions of the ring counts
|
|
|
- to allow a larger number of redundant rings then 2.
|
|
|
-* Investigate always-on flight recorder
|
|
|
-* implement topic-rdmaud
|

|
|
-Ideas for future releases (3.0+)
|
|
|
---------------------------------
|
|
|
-* topic-netmalloc
|
|
|
-* doxygenize include and lib directories.
|
|
|
-* re-evaluate using libtool to link libraries.
|
|
|
-* Support for clang as compiler (depends on libtool)
|
|
|
-* reorganize library/headers/code in the tree
|
|
|
-* change and simplify build defaults
|
|
|
-* libtotem cleanup/rewrite
|
|
|
- * Rewrite totem fragmentation layer
|
|
|
- * rewrite top level totempg interface
|
|
|
- * Split fragmentation layer in totem (ie: totempg talks to totemfrg
|
|
|
- talks to totemsrp)
|
|
|
- * Add a getopt and setopt feature to top level interface to allow
|
|
|
- runtime configuration of the interface
|
|
|
-* Improve cpg - opaque data in callbacks (client stores data about
|
|
|
- itself, every node can access them), permissions (read only/read
|
|
|
- write/ some application may disable listeners) - Probably implemented
|
|
|
- as extra user space library on top of normal cpg
|
|
|
-* Better statistic - histogram
|
|
|
-* totem multiring
|
|
|
-* load balancing over different speed links in RRP

-We use topic branches in our git repository to develop new disruptive features
|
|
|
-that define our future roadmap. This file describes the topic branches
|
|
|
-the developers have interest in investigating further.
|
|
|
-
|
|
|
-targets can be: needle2.1, needle2.X, or future (3.0).
|
|
|
-Once in a shipped version, please remove from the topic list.

-topic-xmlschema
|
|
|
-------------------------------------------------------------------------------
|
|
|
-XML configuration for corosync exists, but imput file is not checked against
|
|
|
-XML schema. This topic is about implementing preferably RelaxNG schema of
|
|
|
-corosync configuration.

-topic-onecrypt
|
|
|
-------------------------------------------------------------------------------
|
|
|
-Currently encryption code is located in totemudp.c, totemudpu.c, and iba has
|
|
|
-no encryption support. This topic merges the encryption code into a new
|
|
|
-file such as totemcrp.c and provides a mechanism for totemnet.c to register
|
|
|
-encrypt and decrypt functions with totem[udp|iba|udpu] and use them as
|
|
|
-requested by the configuration.

-topic-netmalloc
|
|
|
-------------------------------------------------------------------------------
|
|
|
-The totemiba.c driver must allocate memory and assign it to a protection domain
|
|
|
-in order for an infiniband driver to transmit memory. In the current
|
|
|
-implementation, totemsrp.c also allocates these same frames. This results in
|
|
|
-an extra memcpy when transmitting with libibverbs technology. Memory copies
|
|
|
-are to be avoided. The simple solution is to have each network driver provide
|
|
|
-a memory allocation function. When totemsrp wants a free frame, it requests
|
|
|
-it from the network driver.

-topic-rdmaud
|
|
|
-------------------------------------------------------------------------------
|
|
|
-Currently our RDMA code uses librdmacm to setup connections. We are not
|
|
|
-certain this extra library is needed, and may be able to use only ibverbs. If
|
|
|
-this is possible, the totem code may be more reliable, especially around
|
|
|
-failure conditions.
