lib-dict: Keep a linked list of all transactions in dict. This helps debugging if a transaction is leaked.

lib-dict: Track transaction counts

lib-dict: Add dict-fail driver It can be used for providing various failures

lib-dict: Add assert to make sure all iterators are deinitialized.

lib-dict: Add dict_transaction_set_timestamp()

lib-dict: Added dict_iterate_set_limit()

lib-dict: Added dict_transaction_no_slowness_warning()

dict-client: Don't log slow background async commit/iteration replies. If a caller has already finished iteration, or does async commit without a callback, it means that it started the query without caring when it finishes. The caller may already have been doing blocking work while waiting for the dict reply. We don't want to log a warning, because it could be completely wrong.

lib-dict: Added dict_switch_ioloop()

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

lib-dict: Changed internal transaction_commit() to return void Somewhat simplifies the code now that it doesn't have to both call a callback and return the same ret.

lib-dict: dict_iterate_deinit() returns now error string

lib-dict: Changed dict_wait() to return void. If it encounters any failures, it should just make sure to abort any pending async requests before returning.

lib-dict: dict_lookup() returns now error string

lib-dict: remove dict_append() Remove all *_dict_append and redis_append functions and corresponding command from lib-dict.

lib-dict: Added async API for lookup and iteration.

lib-dict: Changed dict.init() API to take struct dict_settings and added dict_init_full(). This allows giving more settings to dict in future as needed. Unfortunately it also breaks the internal dict API, but there aren't really any plugins widely using it, so it's not a big problem.

lib-dict: Added "fs" wrapper dict backend, which uses lib-fs. Each dict key is a separate file where the file's contents are the dict value.

dict: Added support for cdb backend. Based on patch by Hleb Valoshka.

lib-dict: dict_init() now returns error string instead of logging it

dict_init() API changed to return int.

lib-dict: Added memcached_ascii backend.

dict: Implemented dict_append()

lib-dict: Added memcached backend using its binary protocol.

lib-dict: Added initial version of Redis support. The code is a bit ugly and doesn't handle anything except key lookups.

dict: Added dict_iterate_init_multiple(). --HG-- branch : HEAD

lib-dict: Changed dict_iterate API. --HG-- branch : HEAD

dict: Added support for async commits. Changed dict_atomic_inc() behavior. --HG-- branch : HEAD

dict proxy: Use base_dir as the default dict-server location. --HG-- branch : HEAD

Added dict_transaction_commit_async(). --HG-- branch : HEAD

Added a simple flat file dict backend. --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Berkeley DB dict support is now enabled only when using --with-db configure option. --HG-- branch : HEAD

Dictionary changes: Added support for defining value's type. Key is still always a string. Added support for sorting the iteration replies. Added dict_unset(). Added Berkeley DB support. Most of the code written by Tianyan Liu. --HG-- branch : HEAD

If invalid key is given to dict_set() or dict_atomic_inc() fail the whole transaction in commit. Keep track of changes that are actually done, so if nothing has changed in transaction don't even bother to commit it. --HG-- branch : HEAD

Dictionary takes now a username parameter, which is used for private queries. Made dict-sql use "insert .. on duplicate key update" syntax, which unfortunately doesn't work with PostgreSQL yet. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Added dictinary lookup server and a "proxy" dict implementation to talk to it. --HG-- branch : HEAD

Added dictionary API and implementation for SQL. It's meant for looking and modifying key=value pairs. In future we may need to use this for many different things, but for now it's only used by quota-dict plugin. --HG-- branch : HEAD
