Kim van der Riet updated QPID-2017:
-----------------------------------
Attachment: BindingDbt.h
TxnCtxt.cpp
TxnCtxt.h
See notes in this JIRA about preparing these files for ASL
> Files for Async Store interface layer (NOTE, read carefully - license issues)

> Key: QPID-2017
> URL: https://issues.apache.org/jira/browse/QPID-2017
> Project: Qpid
> Issue Type: Task
> Components: C++ Broker
> Reporter: Kim van der Riet
> Attachments: BindingDbt.h, MessageStoreImpl.cpp, MessageStoreImpl.h,
> StorePlugin.cpp, TxnCtxt.cpp, TxnCtxt.h
>
>
> These are the interface layer files for the C++ async store. They are
> encumbered with BDB, which is used to save the broker state. For this reason,
> these files are LGPL - and may not be checked in to subversion until BDB is
> replaced with an appropriate ASF-compatible replacement. Then these files may
> be re-licensed with an ASF license.
> The StorePlugin.cpp file contains the actual plugin code; this in turn
> creates an instance of MessageStoreImpl, subclassed from
> qpid::broker::MessageStore.
> MessageStoreImpl: This class is the centre of the async store and is
> responsible for coordinating recovery, initialization, transactions (both
> local and distributed), flow-to-disk loading and unloading and persisting
> broker state (queues, bindings etc.) in BDB. This class is in need of a
> tidy-up and refactorization - it has become rather large and unwieldy.
> JournalImpl: This is the implementation of the async store. The header file
> is provided for context, as this is used throughout the MessageStoreImpl
> class.
> DataTokenImpl: This is also a part of the async store implementation: an
> instance of this class tracks each stored message through the asyncronous
> write cycle, and can be used to track its status and find information such as
> the record ID (rid) in the store.
> TxnCtxt: This class is the transaction context; an instance of this class is
> created for each transaction.
> The remaining files are for various data structures which are reasonably
> straight forward to understand.
> ASF legal recommends cleaning the files, then re-attaching to the JIRA
> without BDB code & with ASL headers before then committing to svn.
