- misc:
- the 'file log' and 'search log' buttons are now a new widget class that puts an arrow on the side that opens a menu. the secret right-click menus of these buttons is now exposed for all
- fixed a bug affecting some greyscale pngs with ICC profiles--they were coming out pure white due to a colourspace conversion problem
- fixed an import problem when PIL could not load a file (due to file malformation) but OpenCV could. this was causing a failed import from the new ICC profile detection code
- when the downloader hits a broken image file that cannot be imported due to malformation, the status is now 'error' instead of the incorrect 'ignored'
- fixed the duplicate file filesize comparison statement sometimes showing > in one direction and ≈ in the other. it happened when the larger file was between 20/19 and 21/20 times the size of the smaller, just a logic typo (issue #1028)
- the trash maintenance daemon is moved from the old threaded daemon system to the new repeating job worker pool. this is the last daemon cleaned up, so I am retiring the old and mostly defunct 'no_daemons' launch argument. a variety of other daemon infrastructure for things like shutdown checks is similarly removed. the program also now waits for the newer daemon jobs to finish working on shutdown
- moved most client daemon jobs like repository sync and dirty object save down so they start after the first session is loaded rather than right after boot
- if a file is called to regen its thumbnail but currently has no dimension, this is now a no-op rather than an error. in the situation where users force thumb regen before metadata regen and encounter this, it is sorted out later when the metadata regen recognises new dimensions and reschedules the thumb regen
- added an extensive user-written guide to the --db_synchronous_override launch argument to the launch arguments help page. it is possible and safe to run the program with synchronous=0 as long as certain caveats are obeyed. thanks to the user who figured this out and wrote it up
- the downloader engine now discards source urls in an import job if they have the same domain as any existing primary url. this will ensure that if a booru has a link back to itself as a source url, when the 'source' is really an alternate rather than a dupe, it won't be added in hydrus as a known url for that imported file
- misc cleanup in downloader system and file/search log UI
- fixed a type bug in the file and search log 'import from png' action. if you have existing pngs previously exported from here, they will import ok now
- refactored the various hydrus compression code to a new HydrusCompression file
- exported serialisable data pngs such as from file or search log that hold simple Strings now always compress the data before embedding it in the png. existing pngs that hold uncompressed strings should still load ok
- the payload in an exported png is now always compressed, and the payload description always states the uncompressed size
- sped up client shutdown when network traffic has been paused the whole time and a repo sync job might have wanted to run. these jobs also do not hang on a thread worker if network traffic is paused, but they should wake immediately when it is unpaused
