* Use different logging messages when criteria is not available due to mod permissions (property not available to non-mods)
* Change logging level for missing/unavailable criteria to reduce logging noise. On unavailable use debug, on missing use warn
* Improve activity removed/deleted detection based on whether activity is moddable by current user
* Generate perceptual hashes using blockhash-js of images that can be cache/stored
* Take advantage of reddit thumbnail code ImageData to hash lower-res to begin with (but represent full url)
* Refactor imageDetection config so hash and pixel approaches have different configs
* Cache phash results to reduce reddit traffic and speed up performance
Addresses cpu/memory issues with pixel comparison. Allow pixel for finer comparisons if needed using tiered thresholds. Closes#26
* Refactor image comparison to use pixelmatch only so resemblejs can be removed (too much memory usage)
* Heavier usage of sharp to get images into same dimensions prior to pixelmatch
* Refactor image conversion into ImageData to clean up utils/recent activity rule
* Implement staggered startup for bots (reddit accounts, top-level)
* Implement staggered startup for managers (subreddits) and subreddit polling
* Introduce random -1/+1 second to polling interval for every stream to ensure none are synced so there is no instantaneous spike in cpu/traffic/memory on host/reddit
* Add user-configurable stagger interval for shared mod polling
* Implement second image comparison approach with pixelmatch for reduced memory usage when image dimensions are exactly the same
* Use sharp to resize images to 400 width max when using resemblejs to reduce memory usage
* Refactor image acquisition/parsing to use on-demand fetching and track different resolutions
* Try to use smaller previews (under 1000px), when possible, for comparing images and downloading
* Do image comparisons in parallel
* Change 'after' type to string duration for friendlier configuration
* Decrease list size trigger === limit instead of 2x (not necessary to have a list that big for polling new)
* Increase initial shared mod polling to max limit (100)
The list of processed activities SnooStorm uses to ensure only new activities are emitted when polling is never cleared. MayorMonty/Snoostorm#35
To mitigate the memory bloat this creates when RCB runs for a long time on high-volume subreddits implement user-configurable (with defaults) behavior for clearing the processed activity list. Default values ensure clearing the list does not interfere with checking for new activities.
When using full criteria for subreddit state we can save a ton of api calls by get info for all uncached subreddits at the same time rather than individually
* Don't store subreddit state cache results for now since nothing computationally expensive or requires api requests
* Return early on item state check if there is nothing to check so we don't store an empty result in cache
* allow both over_18 and over18 criteria in case user accidentally used name from sub/comm state
* correctly determine if subreddit property exists when testing
* fix cache hit subreddit name logging
* Trim value before parsing
* If not a valid regex string then when generating regex from simple string add qualifiers for beginning/end of string so any matches must be exact
* By dynamically importing the module any user not using image comparison will not be affected by a lack of node-canvas dependency
* try-catch on import and provide a helpful error message about node-canvas dep
Majority of mods that have used this rule assume it does not aggregate on reddit domains by default (only external links), which is reasonable.
So update the default to follow this assumption.
* Add `redditMedia` as distinct domain type from `self` for more granular aggregation
* Use `redditMedia` to fix bug where video and galleries were being counted as `media`
* Allow checking if user is shadowbanned via authorIs (AuthorCriteria)
* try-catch on history get or author criteria to try to detect shadowbanned user for a more descriptive error
