CppCMS Roadmap

CppCMS 1.4.0

HTTP Server improvements

Add Support of multiple event loops

Today, asynchronous applications do not scale well on multi-core systems.

Add required support of multiple event loops so different asynchronous applications would be able to use them.

CppCMS 2.0 and later

Break ABI to fix some design issues. API change should be transparent or almost transparent.

Moving to C++11 + Design Cleanup

Remove deprecated C++03 API (auto_ptr) require C++11 as minimal, replace some of booster tools with C++11 std equivalents where possible.

Cache Improvements

Contention

When an entry is invalidated many requests may try to generate it and create significant load.

Solution, delay "fetch" if some other fetching.

Active Invalidation

Distributed Cache system implements L1/L2 cache allowing a cache client to check if the data is has is still up-to-date without reading it back.

However each access to cache still require TCP-ping-pong.

So instead active cache invalidation may be done: when trigger is risen or new data is stored a sort of a message that causes all clients to drop invalid cache is broad-casted.

Need to be implemented.

Object invalidation

Use cache to invalidate general object

Enable O(1) invalidation and lazy collection

Implementing UDP Support for booster::aio::socket

Booster.Aio socket supports stream sockets well, but has very poor (if any) support of data-gram sockets.

You can open them and use them but there are no operations like sendto or recvfrom that are data-gram oriented.

Add their implementations to Booster analogously to implementations of async/sync read/write operations.

Booster.Filesystem

Implement Directory Iterator.

Implement Locale sensitive Date-Time Form Widgets

ICU provides good features for parsing and formatting dates and times, implement Date-Time Widget for this purpose.

It is not so-straightforward as user should know the format he/she enters the data, such information is not supplied by any existing widgets.

Think what to do in case of no-icu builds.

Replace LRU with 2Q scan resistant algorithm

Check possibility of changing this.

Degraded Mode of work

Problem:

What happens when one of cache/session servers fails?

Solution:

Provide automatic servers fail-detection procedures and continue to work in degraded mode.

Implement Connection Forwarding over unix-sockets

CppCMS forwarding framework allows to forward any connection to other network node over SCGI API.

Is is very useful to be able to forward connections between forked processes of same application.

It can be done in much cheaper between forked processes by forwarding a file descriptor over Unix domain socket and passing already read information via shared memory.
