Hey, noob here, trying to figure out how to get tagging to work. I heard that I could use Hydrus to automatically scrape tags from sites and tag based on hashes, but I can't figure out how to do that. Do I have to wait for the repository sync to finish? So far it's taken several days for it to sync and it still isn't 50% done, it seems to get slower and slower as time goes on. It started off at a speedy 200-300 rows/s, but it's down to 12 rows/s, sometimes dropping to 1-2 rows/s.

I have also had issues with Hydrus lock up seemingly at random. Sometimes it'll start responding, other times the process has to be killed and program restarted.

My system is an AMD FX-6300, 12gb ram, R9 270 if that helps diagnose any issues

Update: After installing the newest update, it seems to run a lot faster!

I just realised I forgot this in the help rewrite this week!

When you have a download page open for danbooru or whatever (if you haven't seen this before, go F9->download->gallery->whatever), there should be an import options - tags collapsible panel. Hit the 'expand' button and you'll have a list of your tag services and the namespaces that hydrus knows how to parse. Set these checkboxes how you want and as the page downloads each file, it will parse those namespaces and pass them to the respective tag services.

If you have existing, imported files that you want to tag with a site's tags, that's more complicated. There's an explanation here:

Under 'tag archives'.

I have decided to work on tag processing a little more this week. I think I'll split it up and push it to idle time, when the user isn't using the program, so it doesn't slow their gui experience so much. I'll be able to make it run a lot faster if I don't have to worry about trying to give the gui time to respond to user actions, as well.

Furthermore, I think with it set to sync in one long go, the db file fragments so much that it slows down hdd access. I suspect that hydrus either vacuumed or your OS defragged between your updates, which is why it is faster. I didn't touch the processing code last week, so it can't be that. Maybe there is some memory bottleneck stuff as well. I'll keep looking. Thank you for your feedback.

Hey, thanks for the reply! I think what may have done it as far as speed is that at one point I removed all of the images and import folders from hydrus because I found that it was pulling in a lot of copies that I had in various folders, and I wanted to go through everything to remove the extra junk, but there were so many images Hydrus was having trouble loading them all without becoming unresponsive. Another issue that I've started having though is that if I try to exit normally, it'll give me a splash screen saying, "exiting gui", but it doesn't seem to ever finish exiting the gui, and so I have to close it via task manager.

Thanks for the help with tagging, once the repo finishes syncing I'll go download some of the tag archives

When it takes a long time to shutdown, it is probably vacuuming, which is basically database defragging. The closing splash screen usually updates to say it is doing this, but maybe it isn't for you. You should to see the client still doing CPU/HDD activity in task manager. In this case, it will eventually shut down, but if you are on the end of a long sync, it might take a while.

Or maybe something in the gui really is stuck in a loop and won't shut down.

When the client is running, try going database->maintenance->vacuum. It'll take a couple of minutes. See if your client shuts down fast after that. You can set how often the client wants to try vacuuming in file->options->maintenance and memory.
