Changelog
Prism-v1.5.8.1
- Adding an automatic reconnect attempt if the db server driver reports the connection was closed
- Adding a connection validation process so we ignore stale connections returned by the pool
Prism-v1.5.8
- Major rewrite of database purge cycle system to resolve issue that allowed queries to be active simultaneously, and fill the pool
- Fixed database connections being leaked when an unrelated exception was thrown
- Removed old code to handle "deferred" blocks. Improvements to our core query system with 1.1/1.2 eliminated the need for it
- Fixed critical error with item/entity rollbacks (planned rollbacks) not being applied after a preview.
- Fixed per-page flag not working.
- Fixed issue with database pool full-reconnect code not being re-assigned properly
- Minor internal tweaks of logging code
Prism-v1.5.7
Requires CB #2700+
- Adding tracking for item insert/remove for droppers (CB 2700+)
- Moved all action lists off /pr params and onto /pr actions.
- Cleaned and updated /pr params help page
- Added new /pr flags help page that lists current flags and how to use them.
- Added command for checking item profile data for currently held item - /what
- Adding config on whether or not to log illegal command and use alerts to console
- Correcting array index error on a small group of container rollbacks
- Correcting NPE on preview cancel
- Fixed issue with item/entity previews being applied before the preview is.
- Changing how we handle counting "planned" restores/rollbacks with preview, so they don't count as skipped.
- Adding system that counts pool exhaustion/db connection errors for the recorder. If a configurable count is exceeded, the system will stop trying to record for a configurable duration, and will attempt to reconnect to the database when it tries again. This will reduce the number of db connection errors in the console, it will properly attempt to recover a db connection if the server is unavailable, etc.
- We won't print a stack trace when it's a pool exhaustion error.
Prism-v1.5.6
- Added default perm nodes so that the alert defaults will not ignore OPs unless set specifically
- Added an internal method of determining if we should cancel an action recording
- Tweak that allows prism to ignore other plugins setting item stacks to 0 instead of properly canceling the event
- Fixed bug with older potion data formats being misread as the wrong data type
- Added config that disables the lookup result grouping
- Fixed calculation bug that showed events between 1 and 2 days ago as today.
- Fixed entity kills being rolled back on previews
- Added deferred blocks to the preview system
- Correcting issue with custom metrics graph
Prism-v1.5.5
Requires craftbukkit 2665+.
- Fixed failure of rollbacks/restores of block-place actions that replaced deferred blocks (snow mostly)
- Custom entity names are properly recorded and restored
- Correcting error with sign text being skipped on restores
- Tracking players punching fire blocks a a block-break on "fire". Rollbacks won't ever restore it though because fire is a black-listed block.
- Using the -extended flag will also disable record grouping, as if using -no-group as well.
Prism-v1.5.4
Requires craftbukkit 2665+.
- Re-merged work that wasn't properly included with 1.5.3
- Fixed a problem with water/lava-break events not recording when water/lava-flow is disabled
- Fixed a regression where splash potions did not properly rollback
- Added trapped chests to list of containers we track a:removes for on block break
- Fixed critical server crash in burn rollbacks due to missing internal extinguish process action in the registry
- Updated internal item alias list
Prism-v1.5.3
Requires craftbukkit 2665+.
- Added initial tracking for items inserted/removed from hoppers by a player. Requires craftbukkit 2665+.
- Corrected first-install not using current schema version, thinking it has to apply updates and generating a duplicate column error
Prism-v1.5.2
Please note: Prism 1.5 requires CraftBukkit 2647+.
- Fixing a database query issue that caused trouble with block parameters
- Fixed a related query issue that caused sql errors, and eventually pool exhaustion errors with inspection wand
- Fixed
/pr
not showing the default page. - Fixed sign events erroring out when another plugin rejected the sign text change.
Prism-v1.5.1
Requires craftbukkit 2647+
- Updated to the new Minecart interface changes with bukkit 1700/craftbukkit 2647
- Fixed player teleport events not tracking properly due to a missing entity assignment
- Add a maxIdle declaration to match the max active, some users saw errors when defaults were higher
- Adding a new config for sqlite users
prism.sqlite.enable-delete-limit
. sqlite doesn't allow us to delete records in batches, unless you have specifically compiled sqlite with this feature. See: http://www.sqlite.org/compile.html#enable_update_delete_limit for more info. Again, we strongly recommend mysql - sqlite is just too limited for a logging plugin.
Prism-v1.5
This plugin requires CraftBukkit Build 2645 for Minecraft 1.5 support.
While Prism 1.5 works wonderfully for 1.5, Bukkit has not yet fully added support for determining the contents and inventory click events for droppers/hobbers, and related information for the new minecarts.
I will release updates as soon as possible as bukkit 1.5 matures.
Misc New Features/Improvements
Minor Additions
- Adding alternate player name syntax so that users can use tab-complete.
/pr l a:place ollie2000 viveleroi
is the same aspr l a:place p:ollie2000,viveleroi
. Thep:
is still useful for exclusions, likep:!viveleroi
, as well as: - Adding support for partial player name matches. Prefix any player's name with
~
- For example, usingp:~vive
you can match anyone with the string anywhere in their username. Just be careful - be sure you know which users match, so that you don't impact people you don't intent to. - Added new parameter
id:#
to specify a single record for l/r/r/p. - Items moved out of your hand are now put back when you disable the wand
- Added dirt/grass to the list of related blocks so the rollback of one's placement won't skip the other
- Added dirt/mycel to the list of related blocks so the rollback of one's placement won't skip the other
- Adding support for properly tracking and restoring firework star data
- Adding new event
firework-launch
, tracks launching firework rockets. Duh? - Adding new event
fire-spread
, off by default. Currently we auto-extinguish fires (if configured) ona:burn
event rollbacks, but if you often have extremely large fires, the ext action may be inefficient. If you track fire-spread, it will be more efficient to run/pr rb a:spread,burn -no-ext
, or if they had access to place the fire block itself instead of using a lighter, usea:place
as well. - Tracking all block-placements of fire blocks. This will show a block-place of fire after each lighter event - and although it seems superflous, it's necessary.
Fixes
crop-trample
on soil without any crops says "trampled empty soil" instead if "air".- Fixed trapdoors on the side of blocks not being tracked when a base block is broken
- Fixed minor error that didn't properly recognize furnace and redstone lamp states as the same block.
- Properly closing db pool connection on plugin disable.
Internal Improvements
- Muliple performance improvements.
- On startup, Prism will now run your purge rules in batches. You can configure the number of records deleted per batch as well the duration of the delay. This way, large purges won't consume the database/pool connections and will spread the load over time.
- Converted to jdbc-pool from the Apache Tomcat project instead of the commons-dbcp pooling classes. They're better maintained and profiling shows they're faster with less overhead/shaded file size.
- Added a custom metric for which database mode is used
- Skipping block relationship checks for blocks that can't have such attachments
- Only passing ore blocks to the orealerts class
- Refactored our system for determining what to ignore so we do all necessary checks before processing an event instead of some before, some after.
Perm/Config Enchancements
- Removed the
prism.alerts.ignore-staff
in favor of permission nodes you can now give players to ignore them:prism.alerts.ores.ignore
,prism.alerts.use.place.ignore
,prism.alerts.use.break.ignore
,prism.alerts.use.lighter.ignore
,prism.alerts.use.lavabucket.ignore
or justprism.alerts.ignore
- Added the results per page default to the config
- Added two new configs for controller how the new purge batch system works.
Proper Vehicle Support
- Adding support for
vehicle-place
andvehicle-break
for powered/storage/normal minecarts, and boats. - Tracking
vehicle-enter
andvehicle-exit
for minecarts and boats. vehicle-break
may be rolled back.- We properly track boat placement even if you didn't put it on water.
- We track vehicle breaks by external entities/players hitting them, as well riders being reckless and crashing.
- Attackers/riders may be either players or mobs.
- Storage minecart item insert/removes now tracked
- Tracking fueling a powered minecart
Preliminary Minecraft 1.5 Support
- Added support for new items
- Adding ore alert config (off by default) for nether quartz ore
- Adding early support for new minecart types - it knows them by name only but bukkit has no API yet to get their contents, etc.
Block/Item Info DB Change
There will be a small schema change to the database (estimated wait time is 30 minutes for 22 million records). We apologize for the wait times but this schema change has dramatic benefits.
- A significant reduction in the number of characters stored per block/item.
- Major reduction in overhead processing during event logging, and database query result retrieval
- Those two add up to a very noticeable performance gain
We originally designed our block data storage system with the ability to track any extra data for items/blocks/entities, but we trapped ourselves into that system for how we track every block - and 90% of blocks don't have any extra data to track. So we've overhauled how that information is tracked.
We spent a lot of time exploring other db schema changes but have seen mixed results in profiling query speeds and will not be making any larger changes.
API: (Major Feature): Custom Event Tracking/Rollback/Restore API
Track, search, rollback, and restore custom plugin events. Links to example api code at bottom
Using our API, any other bukkit plugin developer may now define custom actions and trigger events for them that Prism records - with full support for lookups, action type parameter searches, and even rolbacks/restores. That's right - Prism allows other plugins to provide code to rollback their own events!
Example: Virtual Inventory Tracking/Rollbacks
A developer of a virtual inventory plugin can easily add two new events, say vi-item-insert
and vi-item-remove
. His plugin can fire a custom event that tells Prism when one of those two actions occurred. Prism will record the data like any other event, and the action shortnames will even be included with a:insert
searches.
The developer can also (if he wants to) define a custom "handler" - code that handles a rollback/restore event. This way, if a user does a rollback of an a:vi-item-remove b:diamondblock
the custom code will actually know what to do.
Example: Custom Event Recording
DarkMythos is a plugin that randomly drops spell books from blocks, mobs, and more. The only record of players finding spells is the server log. With only a few lines of code, DarkMythos can add it's own action types to prism, and then fire an event when they happen:
This picture shows the dm-spell-used
and dm-player-cursed
events. There's not much possible for a rollback so DarkMythos just uses the events API as a way to record read-only data - like a player-chat event might.
API: Lookup, Rollback, Restore
Perform lookups/rollbacks/restores from your own plugin.
The lookup API is ready for use. However, with all the API work we've been doing we decided to throw in support for rollbacks/restores through the API as well.
Your plugins can easily define the parameters of the l/r/r action. Prism will handle the process,
and will supply the results to you - whether it's just raw action data from a lookup or the result of a rollback/restore process.
API: Prism Events
Prism will let you know that a drain, extinguish or rollback process has completed by triggering appropriate events. The event contains information about who run it, the parameters, and the block changes performed.
At this time, the events only contain information on block changes - mainly because plugins that will likely use the information need the block data.
