X-Git-Url: http://these/git/%7B%60%24%7BwebArchiveUrl%7D/%22%7B%7D/%7BpictshareAvatarThumbnail%28admin.avatar%29%7D?a=commitdiff_plain;h=4e12e25c59beef296c750fec640b0b80c4c11de9;p=lemmy.git

Adding admin purging of DB items and pictures. #904 #1331 (#1809)

* First pass at adding admin purge. #904 #1331

* Breaking out purge into 4 tables for the 4 purgeable types.

* Using CommunitySafe instead in view

* Fix db_schema features flags.

* Attempting to pass API key.

* Adding pictrs image purging

- Added pictrs_config block, for API_KEY
- Clear out image columns after purging

* Remove the remove_images field from a few of the purge API calls.

* Fix some suggestions by @nutomic.

* Add separate pictrs reqwest client.

* Update defaults.hjson
