Please feel free to ask questions about hydrus here.

As a reminder, the help and getting started guide is here:

I've been trying to scrape some things by character tags off gelbooru lately, but I notice that hydrus can only seem to find between 50-70% of the content for the character. Is this something on gelbooru's end messing with it? For example, there are 770 images tagged as 'hacka_doll_3', but hydrus only finds 464. I assume it's something to do with lolicon/shotacon tags. I've not tried making a gelbooru account yet, but I don't want to have to pay for anything just to save art that's free to access.

Hey, I tried merging my windows hydrus db with my linux hydrus DB by clicking file>import and export folders>manage export folders and then in the destination hydrus client, adding the exported files via file>import files>add folder.

However, this doesn't seem to preserve tags so I was wondering how I could do that?

Additionally, I noticed most of the .webm, .mp4, .webm files failed to import to the new client. Any help would be greatly appreciated!

Yes, I think it is. There's some cookie or something for gelb to unlock spicy content. I'll be extending the login script system to allow adding static cookies so some other users who are working on a new login script can add this, but for now, your best bet is to either add the cookie manually (check your web browser, once you apply the 'show all' or whatever it is form on gelb, and then load up in hydrus network->data->review session cookies), or use Hydrus Companion browser add-on to sync it across automatically:

Check the new 'tag migration' system under services->review services. I assume the tags are under 'my tags', right? Go to that services panel on review services and then hit 'tag migration'. That'll let you export all current tags to a Hydrus Tag Archive. You can do the same on the other end to import to your 'my tags'.

For the videos that failed, what's your FFMPEG version under help->about. For the Linux release of hydrus, it uses whatever your OS has. If it is old (I think current version on Windows is 4.1 or so), try updating it on the system level or putting a static built executable under hydrus's install_dir/bin. There should be a readme there explaining the situation as well.

Otherwise, do you have any of the error traceback 'notes' for the failed video imports? This might help figure out what went wrong. Click the little icon button on the importer that failed and find the import row that failed and then right-click->copy notes.

Yes I can confirm that Gelbooru requires you to set a cookie to access all the content. This is because they recently added an option on the website which hides loli by default. The setting doesn't require an account to toggle because it simply uses a cookie to check if you've enabled it. This means it's pretty easy to set in Hydrus.

Go Network -> Data -> Review session cookies

There should be a cookie for gelbooru.com. The setting you need to add uses name "fringeBenefits", and the value is "yup". That's all you need to do, Hydrus should then import all content.

So I have a weird question/idea about image collections

I have a lot of porn, a lot of amateur stuff.

Now, whats the best way to tag all this outside what you see, how do you identify a person assuming you don't have a name or pornstar name for them.

I'm thinking maybe some kind of either metatag or some kid of hidden identifier tag?

The help guide and the discord make it sound like there's a big collection of pre-tagged images that other hydrus users share publicly. (not from booru sites, images from other users)
How do I access this? Does it have any good memes?

Anonymous 10/06/2019 (Sun) 02:57:17 [Preview] No.156 del
So, I was wondering if there was a way to order my images when they display in hydrus? So, like, before they were in files and had names so I could rename them and ensure that, for instance, panel 1 of a 3 panel comic always came first, and the 3 panels were always grouped together, but I had a large number of duplicates because of the lack of tag support so things that were both "memes" and "comics" would get copied bloating my drive(and there is some shortcut and sysmlink BS I've pulled to help with redundancy with larger collections of like images). Now in hydrus after importing some test images I recently grabbed I'm seeing that nothing has names, but it is out of order. How can I force certain elements to be grouped in an ordered subset when they are visible? For instance when I have a tag "dilbert" with a parent "comics" and I want all the dilbert comics to appear when I include the "dilbert" tag, I want all the comic strips to be grouped together with the panels in order, a consecutive ordered subset, folowed by the next comic strip, also in order, and so on. I expect I will also have an issue when importing full manga and comics. There are also some images from models I have that I don't have a good name for, and where I don't know the name of the model, but I would still like to be able to select them all and group them, and give them an order so similar images appear one after the next(If I have to manually order them this is not a huge deal, though I have enough doujins in particular it would be nice if I could import that based on the file name somehow so I don't need to manually re-order thousands and thousands of files).

Also, I have a slightly different question. I noticed there is some kind of special tag for system inbox and system archive, but I'm not sure what the difference is? are they just local collections, or something else, and if so can I make my own custom collection and sub collections?

Has anyone been using an image viewer to interact with Hydrus? I know it has its' built-in image viewer but I've been thinking about something more minimalist, something without any menus, only a thin border that'll change the the shown image at every 10 minutes - this could be configurable - or by a shortcut. In other words, an image viewer that'll use hydrus as the backend. Maybe this could be added to Hydrus even but it seems like too much to ask from hydrus dev.

My biggest thing about tags is that they are for searching, not describing. If you are likely to search for 'amateur' or 'blonde hair' or 'favourites', that may be much more useful to you than person names. If you do not know the name, I recommend you leave that blank until you do. If you sync with the PTR and these are likely to be on some 'realbooru' or similar, another Anon will probably eventually add the right person: tags for you either manually or by parsing a booru they are on.

If these are for 'my tags', you can of course do anything you like, but in general, I have learned that trying to tag everything you see, or try to do anything like a 'perfect' job, is a rabbit hole with no end and very low productivity.

You could try a kind of 'artist request' tag for 'person' if you like, like 'unidentified person', as a 'my tags' tracker just so you can revisit these files at some point.

I do not know of any large public file repositories. I know some users are playing around with them in private, mostly 1-5 friends sharing kind-of-thing.

I used to run a simple file repo that had a couple hundred of my old imageboard files and some fine art, just as a demo for how the tech works, but I no longer run this. Perhaps that was what you had heard about?

Hydrus is not excellent at paged content. I hope to improve this in future, along with more general cbr/cbz support. For now, try adding 'page:1', 'page:2' and 'chapter:10', 'volume:5' and 'series:blame!' style tags. It takes a little effort to set up, but you can often regex-parse these from your original file import filenames. Then, in the client, set it to sort files by 'creator-title-series-volume-chapter-page'. This will line things up nice, but the workflow, particularly for editing things once in the client, is not as I'd like it.

inbox/archive is a hardcoded special 'tag' that works like your email inbox. New files start 'inbox', with the little envelope icon, and then if you decide you want to keep a file (e.g. it was not some garbage you downloaded by accident), you hit F7 to archive it. The system:inbox/archive system search predicates let you filter by these statuses, letting you set up a 'filter this new stuff' page or 'look at this good stuff' page. It is just a neat way to keep track of new and verified 'good' files. Check out the 'archive/delete' filter as well, as per here:

It is parsed from the website at the moment. It is not currently user-editable. If you edit the parser, you can change what gets added, but this is fairly advanced.

If you are making a thread parser and want to see how it works, check out the existing 4chan/8chan defaults to see how I did it. There's a special content type you attach to your content parser, and that value gets sent to the downloader object for its 'name'.

Due an issue on my HDD, I've lost some files from my data folder. Specifically, 6 full folders, to the tune of 3600 files. I have a recovery program running, so I might be able to find them. But if not, I have the thumbnail folders still available, so I could reverse search to replace the files manually. If I did this, ended up with a slightly smaller version of the file, put this file into the correct folder with the correct name... What would happen? Would it break my database? Would it still be tagged with the previously saved tags?

tl;dr: If I replaced an image with another of the exact same name, but it didn't have the exact same properties, what would happen? Would the file still have the same tags? Or would it just bork everything?

Anonymous Board owner 10/08/2019 (Tue) 00:31:24 Id: ea6894 [Preview] No.179 del
Some different things would happen depending on various maintenance timers. The client does not constantly monitor its file store, and it only ever accesses a file when it needs to do something with it like showing it in the media viewer. It does not rescan a file when it loads it.

If a file were to change, the client will try to load it with its current understanding, so if you swapped one jpeg for another with a different resolution ratio, it would probably draw it ok but all stretched to the wrong size canvas. It wouldn't lose the tags for those files, as tags and so on apply to the db store's understanding of the file, which is still all correct for you. It might sperg out if it needed to generate a thumbnail or something else clever.

A problem would come if hydrus ever did file maintenance on those files. It would recognise the files had changed in terms of bytes and throw some errors, and probably remove the file and put it in a 'missing_and_invalid_files' directory in your install_dir/db directory. Maintenance can be triggered by things like thumbnail resizes gone bad, so I expect these weird files would get looked at eventually.

I recommend you make a copy of those thumbnail folders, just in case you want to try something clever with them later. Then get the client going with empty file folders and go database->maintain->file maintenance->review scheduled jobs and then add a 'check if file is present in file system' for a 'system:everything' search. Force it to do that job, and it'll clear itself of the missing records and export all those files' known urls to that 'missing_and_invalid_files' directory. There will be a 'all_urls.txt' masterfile, which you can open, copy-all, and then paste back into a 'urls' download page in the client. The client will then download all those correct files again. This will make for a more 'correct' db and get you nice files again. It would not work well if most of your files were not downloaded and do not have nice known urls.

If you wanted to have thumbnails in lieu of the files, it is probably safer just to import those thumbnail files, although they won't get the tags of course. There's the slightest chance that your png thumbnails will be the same file as the original png, but I can't say that with confidence.

Let me know how you get on here.

Hydrus isn't saving any page changes. Whether I import files in a URL import page, close a page, or open a new page; closing the client and reopening it reverts any changes. The files I import are still in the database, but they don't appear in the page where they were imported. Any idea how I can fix this?

It only works for hard drive imports, and works on file paths. When you drag and drop some files onto the client and it opens up the window with the list of files to import, click the 'add tags based on files' button, which will launch a new, more complicated dialog. The 'advanced' tab here lets you match tags based on some regex rules.

Here is the API stuff, if you are interested:


There are links to several libraries, and a nice python interface that makes it easier. The API isn't 'complete' by any means, but I am slowly adding more to it.

I can think of two possibilities:

1) Is your default gui session under options->gui pages 'last session', or something else? The 'last session' is special, and is saved regularly and on exit, but if you have it set to something else, you will need to re-save that session if you want the next boot-load to reflect those changes.

2) If your session is gigantic, it may be that hydrus is having trouble saving it, and because it is doing so on exit, it is unable to report that error properly. Does your session have millions of total thumbnails&urls in it? Or are you on a slightly lower-end machine, with say 4GB ram? If you look at your install_dir/db directory and look through the latest client.log, are there errors in there about your session?

Well, whatever was wrong seems to have fixed itself. My default gui session was set to 'last session' and there weren't any errors in the client.log file. I have 16GB of RAM, but my web browser was eating up quite a bit of it. Maybe that was the issue? Anyway, thank you for the help!

Hydrus Dev says he uses ToDoList in the Hydrus documentation. https://hydrusnetwork.github.io/hydrus/help/getting_started_installing.html
The link in the docs goes to a 404 page, but the homepage http://www.abstractspoon.com works fine.

Yeah, that's the one. I'll fix the broken link, thanks.

ToDoList is tremendously customisable. I prefer to cut down almost all of the features to just time_due, recurrence, and job name. If you find there are too many fields to customise, don't be afraid to just hide them. I have many daily tasks and also birthday/dentist tracking and so on. Most of them re-occur every day/week/whatever. Even stuff like 'check this web page for new vidya releases this month that might be interesting'. Probably 200 jobs a day, it runs my whole life.

Hmm, thank you for the note about your session as well. I am not sure if that was it. Maybe memory shortage was stopping the session from packing and saving right, but I would usually expect you to see OS warnings at that point.

Are there any plans to include Hydrus in some package manager's repo? I'm talking about stuff like NixOS or Guix System, since they seem to be pretty interesting package managers to use, and in the case of Guix, I know you can run such packages on other distros without Guix.

Is there yet a way to default exclude a tag/namespace from searches that don't explicitly include them in the query?
Like if I were to blacklist "pepe" and I had an image tagged with both "pepe" and "meme," querying "meme" would not bring up that image because I explicitly didn't include the blacklisted term "pepe" attributed to it. I'm aware that I could get this functionality with "-pepe" in my search, but it's not exactly the functionality I'm seeking

You could add a "Show" tag to all whitelisted items. I actually uses a "visibility" namespace and I use the subtags "public","school","work","politics","family","personal", and "private". Unfortunately, this way if you want to show "school" and "work" you still have to '-' the other tags, but to prevent people from knowing I have edge lord "offensive" memes like PePe, NRA, and right wing memes, I just stick them in politics instead of public, and I do a similar thing with the "private" tag which is also a namespace for "sexy", "porn", "ecchi", and "hentai" Maybe that will help you if all you want to do is keep people from seeing your dank memes when working with colleagues when searching for a flowcart, etc? Still not perfect though and the having an | operator for queries would be really nice.

That said, my question is, is there an easy way to download galleries from sites like https://mangakakalot.com/
while preserving all the tags? I actually wrote a macro to automatically use hotkeys to grab URLs to the clipboard and generate the image downloads to attempt(by parsing the URL to the gallery and generating 3 entries per image (the page number followed by the extension[jpg,png,gif]) but this is slow, and wastes a lot of time waiting for non existent images to timeout, as well as having sites like https://e-hentai.org/ using obfuscated URLs that make it impossible to tell how to generate the image from the URL pattern alone(and I'm not a web developer, so I don't know how to loop over the next pages on the site through script to grab the image links...).

I have a bunch of manga stored into different folders by story, and along with the pictures each folder has a .json file with all the tags and data like title and page count. How can I import this into hydrus easily? Doing a few folders manually wouldn't be a big deal, but I have probably collected around 1500 or so folders of manga, maybe more. I don't want to have to manually add 1500 files and all the tags when the data is already there in json, and is probably parse-able in some way

I am not totally sure what you want to do here.

There's a paste button beside the text input--if your clipboard has newline-separated urls, it should pull them all in one go. I know some users who have pasted like 10,000 urls all at once like this.

Have you tried this and not had it work? Did it not split by newline? Do you know if your text editor is using NL (newline) or TLCR (newline-carriage return)? I think it is supposed to be able to handle either, but maybe it is misfiring.

There is no way to do this at the moment, but I expect to add it at some point. Can you say how ifran view takes multiple files as a launch parameter? Is it something like:
program_exe file1.jpg file2.jpg file3.jpg

Different programs have different 'playlist' formats, so I'll have to extend the 'launch external program' code to have some way of describing that.

I have been on the hunt for over two hours now, and I feel it is now time to ask a professional: why is my regex, that works the way I want in an online simulator, not working when I actually use it in hydrus?
The attached picture is there to show what I am trying to do:
I want the yellow marked column in a month:xx and the red circled column in a day:yy namespace, but as you can see my shit is being fucked up here.
I basically want to know what two regexes I need to perform to get the month and the day filtered out, so that I can put them in two separate namespaces.
Sorry if this is a stupid question, but as it turn out I am too much of a brainlet for regex.
The second picture shows that I had theoretically figured it out, but to no avail. :(

Hey, yeah, regex is a pain in the ass at the best of times, and the way I apply some of it isn't totally standard.

Just a quick thing, if it happens to help, hydrus is in python rather than PHP. I'm not sure there will be any big differences, but maybe in some edge cases.

I think in my regex parsing there, I get every matching string, rather than just the first, as perhaps that online one is doing. If you want day and month with those paths, I'd probably go for:

month - (?<=\\\d{4}\-)\d+
day - (?<=\-\d\d\-)\d+

I am making sure the look-behind matches the right number of numbers (\d) in order to capture the second or third group in the yyyy-mm-dd set.

Ah, was just checking back to look for the answer, and I saw this reply to another post: >>197
I think I want to do this, but with URLs. To be clear, all the images do import properly, but the information about the title and page is lost which I'd hoped to parse into tags using regex from the URL as it is part of the path. Doesn't look like that's an option though? In that case I would like to suggest/request you please support that feature if you can? Would be really handy.

If I add a "hydrus tag repository" and point it at the PTR, will it sync all my current private tags, like person:<familly member name: last middle first>
? I've spent a lot of time tagging my personal familly photos and vacations with relevent tags, but I would prefer to not leak those to some public repo. I want to tag a bunch of images I grabbed from boorus and chans though with the PTR. I've read the help article, but exactly what happens with my local tags is still very confusing. It also talked about "committing" tags to the repo? What if when I'm setting tags 99% of the time it will be for personal use and I don't want to push them to a repo? It mentions that you can have multiple repos, but I can't find more information on this in the help.

When tagging I used to be able to enter a namespace and Hydrus would suggest me all tags of that namespace, which was really crucial to my "workflow".
Today I updated after skipping several versions and that isn't the case anymore.

Is there a way to re-enable this? Can't find anything under "tag suggestions" in the options.

Core parts of the 'old place' are (more-or-less) back online, so smaller boards have been given a deadline of 2nd December for the former Board Owners to verify / claim their boards, which will restore them to their pre-shutdown state; have you secured the /hydrus/ board yet?

Anonymous Board owner 11/24/2019 (Sun) 02:02:54 Id: 3e4345 [Preview] No.372 del
Hmm, yeah, you can parse tag info from URL string easily at the moment. You could probably wangle a custom parser to pull this, but it would be impractical for real use. Is there any chance the title/page info is available in a web page the file is in, like you would see in a gallery site like Hentai Foundry, or do you only have access to a raw jpg file URL? Normally, hydrus likes to grab that data from json or html.

Converting tags to ratings, or ratings to tags, or now tags from URLs, any sort of cross-metadata-type conversion, is not really supported right now. It is complicated and requires a bunch of new UI. I am not opposed to the idea, but I don't think I could fit it into normal weekly work.

I will soonish be adding the ability to easily export and import URLs using neighbouring .txt files. It is possible you could cobble something together here by exporting the files you care about here with their URLs in a txt file, using a script to convert the urls.txt to a neighbouring tags.txt file, and then importing those tag .txts and the files again and pulling the tags. Is that something you might be interested in, or is it a bit too inconvenient?

No. When you add something like the PTR, it'll make a completely separate service that will appear in the manage tags dialog as a second tab. PTR tags will stay in one list, your 'my tags' will stay in another. Any time you choose to edit tags, or to parse them from something like a booru download, you will be choosing which tag 'domain' they will go to.

Normally when you search on search pages, you will see the tag domain is 'all known tags'. This is essentially a union of all your tag services, which for you at the moment is just 'my tags'. It'll be 'my tags' and the PTR if you add the PTR.

The only way the tags you have added to 'my tags' can be moved to the PTR is if you specifically choose to. You might copy them from the 'my tags' page and paste them to the PTR's, or you might do a larger migration using services->tag migration. If set up to sync with the PTR and touch nothing, no privacy violation will occur. You can't really make a 'mistake' here unless you are specifically reckless, you have to choose everything.

The 'commit' part is a special part of sending tags to the PTR. Rather than upload immediately, when you add them to the manage tags dialog, they are instead in a local-only 'pending' mode. This lets you edit them if you like before you commit by uploading them to the server. When you have pending tags, you will get a new 'pending (count)' menu in your main gui's menubar that lets you send them all up in one go when you are ready. This is the only way that tags can ever be uploaded to the public space--you control it completely.

If you do wish, you do not ever have to pend a tag to the PTR, and can use it exclusively in a read-only way.

If you want to get a feel for multiple tag services, try going into services->manage services and adding a new 'local tag service'. Call it 'clothing' or something and experiment with the new 'clothing' page you have anywhere you edit tags.

Let me know if there is anything still confusing. Thank you for your feedback, I will improve that help.

Thanks. Yep, we should be good, assuming it actually comes back ok. I sent an email a few weeks back, along with dozens of other other BOs, when they sent out a tweet asking for emails with shared secrets, but unfortunately those emails it seems were not actioned. Most of us did not get replies, wew. I guess they got eaten when one of the domains got killed.

Today on another bunker, there was a thread to figure out the mess, and /hydrus/ is now on an explicit list for migration. My BO username and pass don't work atm, let's hope they do in December!

I am not super enthused about the new terms of service or the situation in general, but we'll see how it goes. If most of us end up shitposting there again, I'll cheerfully run /hydrus/ from there too, but if we don't, or they can't stay up, I'll throw up a poll to figure out how people feel about different places for a permanent home, here on Endchan or elsewhere.

The only site I have kind of working, is https://nhentai.net/ I navigate to the last page and hit a key that runs a macro to copy the current URL from the clipboard to parse it and generate the page numbers. I then click on the floppy icon to paste this as a URL download. Unforunately, I then have to manaully enter "Page:1", "Page:2", etc, which is the most annoying part as it must be done for every page. However as the URls I amp parsing are formatted like this "https://i.nhentai.net/galleries/1516309/2.jpg" where the 2 at the end is the page number, I had hoped to regex pars that for each image as it downloads. I have another hotkey macro that lets me select the tag text for all the images in the gallery and parse it into the multi-line tags that hydrus understands. But currently, my macro that tags the page numbers needs to wait for all of the images to download, then I give my macro the number of pages, and it uses keyboard controls to add the page numbers by hitting "home" sleep 1000ms "f3" sleep 1000ms "page:x" sleep 1000ms "enter" sleep 1000ms "right" and then it repeats from the "f3' key. but, this always takes at least 4 seconds to run plus some time wile waiting for the window to activate. So if I have 600 images in a doujin it I have to leave my computer running and not touch it for like 40 minutes minimum where I can't do anything. This is better than manually adding hundreds of tags, but I would prefer to be able to parse at least the page from the urls I paste into the URL downloaded to a tag for just that file. Btw, if anyone is interested in the Auto hot key scripts I wrote to do this, here they are:

So, I added the PTR to my hydrus and let it sync overnight, but it looks like non of my files have been tagged with those PTR tags? I thought the Syncing was to download all the tags and the hashes for the files that would be recieving those tags, and then they would be applied? But this doesn't seem to be how it works? So how do I get my files to update their tags from the PTR, and do I need to broadcast the image hash as a fetch to the PTR or something to get the tags back? If possible I would rather not leak hashes either, or be able to just look up a subset of my files and try to fetch tags that way if this is the case? Or is there just some setting I have missed enableing that would let my client used the data I have already spent all night syncing tag my files? Because I assumed that I was essentially syncing a dictionary/map of Dictionary<string, vector<int>> lookupTable. where string was the tag, and int was the hash? Or did I just sync tags/keys when DLing the PTR? And how do I see what tags I actually DLed?

Is there a straightforward use case to sync a database between two computers on LAN?

I use both a laptop and a desktop and I store my large media on a NAS, so I'd like to manage the same database no matter which computer I'm using. Network mounting the hydrus directory would probably be too slow (not yet tested), and I'm wary of running a full server per the warning above help/server.html.

Thank you for your work on Hydrus!

Hey, I am sorry for late reply. Did this fix itself? It is possible that if you do a huge sync from nothing, you might not see tags until the next client reboot. You can check this by opening a new search page, changing the tag domain from 'all known tags' to 'public tag repo', and then doing a search for system:number of tags>0. Does anything show up at all?

The PTR in hydrus should just make tags appear, you don't have to do anything but wait for some syncing. If you check the PTR's page under services->review services->remote->tags->ptr, how far is the 'processing' stage done? Is it mostly finished? It should have a mappings count, and as soon as you get, say, 50 million mappings, you should see a bunch appearing on older popular files.

For some situations, tags will not line up with a file. A couple of hydrus users had run their files through image resizers/optimisers years ago, and since the file content here has changed uniquely, those files will not line up with the (hash, tag) pairs the PTR offers. But if you have any decent sample of original files from the big boorus, you should see some tags from the PTR.

Here's a picture of Samus:


If you select and drag and drop that URL onto hydrus, it should import into a new page. The file has tags on the PTR--do you see them?

I dont know which of these boards is used more so im gonna post here too.

Im getting disk I/O errors because my hdd is presumably dying on me and I neglected to make any backups of my database. I move the entirety of the db over to a new drive successfully except for client.mappings, I get errors whenever I try to move or copy it. Am I fucked?

I have tried cloning it in sqlite, seems like its getting stuck at current_mappings_10.

The program also still works fine, no tags seem affected though I dont really know what client.mappings handles. The only reason I noticed something was wrong was because I suddenly couldn't process repository updates.

It stores the tags. You are not permanently fucked, but it might take a little work to get back up and running, and if you have a lot of 'my tags' (as opposed to just, say, the public tag repository), it may be trickier.

It may be simpler to do this one-on-one by email (hydrus.admin@gmail.com) or discord DMs (https://discord.gg/3H8UTpb), but we can also do it here.

My best first suggestion is to try to copy as much of client.mappings.db to the nice drive. If your OS is doing some of the move but sperging out and cancelling due to a bad hard drive sector, maybe a program like FreeFileSync will let you copy most of the file and still leave the truncated half-copy in the nice drive after the error. I am not sure if FFS will do that, but I think some copying program or command line call will be able to do the front half. You may have more luck cloning this half-copied db, and if that works you should be able to just boot and reset your PTR processing cache and be back up and running.

If you absolutely cannot copy any of client.mappings.db, we'll have to see if we can possibly create a barebones one and fool the client into thinking that is the correct one.

Great, I am glad you are basically working again. If you used a 'fresh' client.mappings.db, you will run into trouble sooner or later when you add new tags or process the PTR. The tags you see are probably being nicely loaded from the fast caches on client.caches.db, but the actual tags (and the storage areas where they should be) are missing from the real-deal client.mappings.db. This may need you to hit services->review services and completely reset your PTR's processing, to reformat client.mappings.db and fill it up again properly.

Also, if you have local 'my tags', they may now only exist in the semi-ephemeral client.caches.db. Make sure you have a good backup of this current 'working' db before you do anything crazy, as they may be wiped by a big 'reset/recalc' action.

The 145k tags is for the 'pending (145,000)' menu, right? This again is because it thinks there are pending tags, but the actual ones have disappeared, so it is out of sync with the db. We can reset it, but this may cause an error. Hit help->debug->data actions->clear db service info cache and then restart the client, which will force it to re-count that number from raw db tables. I expect the true number is 0, so the pending menu will disappear on restart.

Let me know how you get on. If you have a lot of local 'my tags', make sure you have a backup of client.caches.db at least--we may be able to do some SQLite magic to re-populate the missing tables in the bare client.mappings.db.

Yeah, it is a constant battle. You can go crazy falling down this rabbit hole, and it is easy to become unproductive. My very strong tl;dr recommendation in tagging is to follow two rules:

1) Don't try to be perfect.
2) Only add tags for things you search for.

Tags are for searching, not describing. If you aren't searching for 'series' tags, don't get lost in them.

Delete the App from Applications, and delete the folder at /Users/You/Library/Hydrus. That library folder is all my code writes to permanently. If you want to be very thorough, clear out your OS temp folder, as there may be some old temp files hanging around if you have had crashes.

I am not an expert at macOS. Perhaps there are also some system shortcuts or history or something that is added at the OS level. If you know macOS does this and you want to completely wipe all memory of hydrus, you'll have to search how to do this.

Hey, just catching up after Endchan downtime.

There is no way to do this at the moment. I am ultimately unhappy with how collections work in many ways and want to clean up and rewrite handling of multi-page content, both with explicit cbr-style file support and a virtualised 'single object, multi-file comic' cbr format to handle paged comics as single thumbs rather than auto-sorted files.

I apologise for the inconvenience in the meantime. The next time I am in that code, I will see if adding a simple double-sort system as in >>523 is easy to add, but if not, this may have to wait for the bigger rewrite.

>to handle paged comics as single thumbs rather than auto-sorted files
when/if you do this, you should give priority for files tagged as "doujinshi cover", "cover", "medium:cover", "cover page", "doujin cover", etc, as the thumbnail.

It's fine. In the mean time, I'll just hold off on importing my comics and series until I can. If I imported them now, the individual files would just get in the way, since "random" is the primary way I browse.

I agree, but if that were to be done, then instead of it being hard-coded, there should be an option to set which tags get thumbnail priority, and maybe just have the tags you listed be the defaults. This ensures flexibility in the case that there are other groups of files where one kind makes obvious sense as the thumbnail.

When adding tags manually, there's an option that auto-replaces old siblings with new siblings when you enter the old sibling, but it can be disabled, and I do. How do you disable that for tags that are automatically added through the gallery downloader. I checked the tag import options, but I didn't see anything about siblings there.

I'm importing files from Sankaku Channel, and I want the tags that are imported into Hydrus to be the tags that are there exactly as they are on Sankaku Channel. For example, I have 1boy as the old sibling of "1 male" in "my tags" but when I import a file from Sankaku Channel, "1boy" is just replaced by "1 male" entirely. I don't want that to happen. I want the underlying tag that's imported to still be 1boy, even though it will displayed as "1 male" since it's the old sibling.

Thanks, I agree. I will have to be careful about how we do this stuff. As we have found with collections, page: tags are not comprehensive.

For a long time, I have thought that virtual comic support in the client, and related tasks like 'please tag these twenty files with page:x, starting with 17 and adding 1 each time' really needs thumbnail re-ordering with mouse drag and drop.

Once we have that, it will be much easier to solve niggling file sort problems where a comic has 'main page' vs 'front page' vs 'copyright page' vs 'last page' in just a couple of mouse drags.

When a sibling relationship is created or petitioned to the PTR, the changes show up for you, even if it gets rejected by janitors to be shown to everyone.

This sounds a very long time. Normally SQLite is ok at this stuff, sometimes as slow as 250KB/s, but rarely that bad. It could be due to abnormally high drive latency (which could be due to it being mechanical and over a usb, and/or it being very very fragged), or your machine being very tight on free memory (so your OS's disk cache cannot populate, or perhaps the drive itself is having trouble.

Were you able to run a program like CrystalDiskInfo? Is the drive itself healthy?

Run time normally scales with file size, so if your client.mappings.db is 20-odd gigs, it could be several days to run. This sounds ridiculous to me, so I would suggest you cancel the job and figure out what is wrong with the connection to the drive first. It would likely be easier to copy the file to your system drive with sqlite3.exe, especially if it is an ssd, and run the integrity check there.

Please let me know how you get on.

Unfortunately, there is not. In its development, the biggest problems with the tag repo code have been in dealing with its growth, and admin and user controls took a back seat behind the back seat.

This is now a bigger deal, and the PTR janitorial team have given me some suggestions as well. I do not know if I can make it as nice as you want, but when I next do a big iteration on tag repo content updates, I expect to add better client knowledge of clientside changes, the ability to make changes locally and not upload them, and likely some sort of anon 'petitioner id' so you can see your petitions' results and exchange anon messages with janitors.

Hmm, not completely. There are some options under options->connection that limit how many network jobs can run at once, but that isn't really what you want.

The client's ideal has generally been to run all simultaneously and let the bandwidth rules slow things down, but there are some hardcoded limits, I think around about 10 or 15 file and gallery downloaders running at once, to stop some back-end things getting gummed up.

I could just expose those hardcoded options to you, probably on options->downloading, so you can set them as low as you like. I'll just say/warn that these limits are hacks that I put in an emergency because the system grew faster than my back-end could deal with it, so it is a bit ugly--downloaders that are blocked by this limit just sit there, no status updates, because they can't even boot to say they are paused. The whole system is pending a rewrite, but if you want to artificially limit, I can keep those options in the new system.

Just downloaded 401, first time actually using this software.
I have no doubt my use-case is a little unusual, but as I begin tagging my collection (a scant 2,000 images but I want to be able to find old vacation images but I can't remember which vacation it was) I find myself wanting to remember if I tagged this aspect before, and if so how I spelled it, etc.

It would be very helpful if I could find a list of all extant tags, but the closest I seem to be able to get is to stop tagging, search system:everything, choose no particular image, and scroll up/down the left where the associated tags that overlap with the current image search results are shown. Then I have to write down the one I used last time, then go back to system:inbox and find what I was about to tag.

It would, as I say, be useful if there was a toggle I could throw, that would populate "recent tags" with instead "every tag" although if the client is allowed to sync with the PTR that list would be both ponderous and useless. So, maybe a toggle for "all *my* tags"

On an unrelated note, and a note of thanks, it took me some time to find how to search for images by their ratio. But I'm very grateful I don't have to create a namespace of 3, with a single member of 4, just to indicate I tipped the camera on its side for that photo.

In hydrus, I have it set to automatically import tags into the PTR when I download images from websites. Most of these tags that are imported are correct but sometimes they're wrong. If someone else sees these incorrect tags and removes them, will I ever get those changes, or does it work kinda like tag parents and siblings where, because I (technically, though it was automatic) added those tags, changes to them by other users will be ignored and I won't sync those changes.

I have tag-importing on because I think that overall it does much more good than harm, but if I have to individually correct every misapplied tag, that probably swings the balance in favor of it not being worth the effort for me.

Yeah, if a janitor cleans up a bad tag, it will be deleted your end within a day or so, even if you were the original uploader. No worries, sending typical booru tags up to the PTR is a good and useful practice.

Siblings and parents work a bit different since a janitor needs to approve to add them in the first place. In that situation, where the sibling or parent was never approved to be added in the first place, your client keeps them. But if you add a sibling, and it is accepted (and hence sent to all users, including, redundantly, to you), and then it is later deleted or reassigned in some way, you will get the deletion update.

So all tags that you add or remove are added and removed for other users, and vice versa. Good to know, thanks!

I wasn't aware of this. Thanks for the info. This should probably be stated somewhere on the help pages. I was under the impression that once you add or remove a sibling or parent from the PTR, your client basically ignores everything after that, and you're on your own.

Is there any way to select the desired search distance in the duplicate filter for each search? I like having 10 prepared for some cases but it does tend to give me a lot of false positives most of the time.

Hmm, I don't think so, I am afraid. Do you mean like when you want to do some dupe filtering, say 'only show me things that are tagged 'blah' and are also exact matches' and such?

At the moment, the actual dupe system does not store search distances that pairs were found at. All that works in the discovery side, which works on a different search system and data structure than the dupe system proper and normal file searches.

If it helps, the likely next step for the dupe system for me is to write a checkbox or something for 'only show pixel-for-pixel-duplicates', as part of a push to early user-customisable auto-resolution rules. Once we can do the easier issue of pixel dupes, I expect the natural next step will be to add search info for very similar dupes (like 'if the files are 99.998% similar, follow these rules').

In the PTR, there's a tag that's incorrectly applied to a file. I tried to remove it, but in the "manage tags" window, there's no tag there to be removed. As a test to see if it was a sibling that I just wasn't noticing, I petitioned every tag to be removed (to see the -1 on the tags) and that tag DIDN'T have a -1 next to it. What's going on here?

If this is some sort of moderation thing by the people who run the PTR and the tag is unremovable for some reason, then is there some way that I can locally override that, and have it be removed on my client specifically? I know that the tag is incorrect, so it's a little annoying that I can't fix it.

Anonymous Board owner 09/19/2020 (Sat) 21:44:55 Id: 2dd545 [Preview] No.800 del
Hmm, no, that sounds like a bug. There's no 'pinned' tags system atm.

If you type the tag in the manage tags dialog autocomplete, does it appear to be in any siblings? e.g.:

the ghost tag is "character:samus aran"
you type in "samus"
you see "samus aran (will display as character:samus aran)" in the list somewhere

There appears to be a bug in the new siblings code where sometimes a sibling implication does not remove when the base tag it was implicated by is removed. I am still chasing this down. It seems to occur more often from tag changes by the Client API, but it does not sound like you have been using this to edit tags.

I don't have a good maintenance task to fix a small number of bad files in the case of a miscount, but I will write one when I get to the parents cache in a couple of weeks.

The tag in question is "2 females", so it appears in plenty of sibling pairs as the "new" sibling. That's why I clicked "petition all tags" to make sure that it wasn't just that I missed a sibling that I didn't know about being displayed as that tag.

>It seems to occur more often from tag changes by the Client API, but it does not sound like you have been using this to edit tags.

I don't even know what that is, so I don't think I'm doing any of that.

It's good that this is a bug though. I thought it might be a feature. Having tags from the PTR that I can't remove, at least in my own DB, would've been a dealbreaker for using the PTR. I can't have the PTR tags eternally ruining my searches and there being nothing I could do to fix it for myself at least.

I was able to reproduce this and fix the bug for 414, which should be out on Oct 14th. There should also be some better maintenance tools to fix files' presented tags in these cases. The bug was when you remove two sibling tags that both point to the same thing at once (i.e. in one dialog apply). A quick fix for now is to go back in and add/remove one of those sibling tags to reset the calculation. Thanks again for the report, and I am sorry for the trouble. Let me know if you run into anything else.

At the moment, I do not have options for this. The client tries to pull from your system UI scaling value. I will introduce some better font scaling options in the client.

For now, if you add this text to a new qss file in install_dir/static/qss/, and then set that as your style in options->style, you can force different font sizes:

/* You can set the pt value to whatever you like */

font-size: 14pt

Tag siblings and parents are now virtual at all times. Unfortunately, it was too technically complicated to maintain a system that could do both soft and hard replace, and it was too difficult for the PTR janitors to manage clients who could hard-spam variously incorrect tags based on personal sibling relationships. The PTR problem would have only become worse as I added the ability to apply different services' siblings to each other.

So, for now, the ability to hard-replace tags with their preferred siblings is gone. Tags show more reliably as their sibling ideals in normal displays, but they aren't stored that way. The nice thing about this is that siblings (and parents) are now completely undoable in the case of mistakes.

I expect to add in a different system for hard-renaming and so on, for local tag services, in the future. It will be a different system than siblings, probably called 'alias' or similar, as some boorus do.

If you want to change how all tags of a certain kind display, for instance changing all 'samus_aran' to 'character:samus aran', you want the 'siblings' system.

If you just want to add or remove tags from a file, select it in the thumbgrid and hit F3 to open the manage tags dialog.

If you want to do really clever large-scale deletes or other operations--although be warned this is advanced--the best tool at the moment is tags->migrate tags.

Hmm, I am not sure there is, I am afraid. You can manually jigger rechecks for URLs when the file is actually at the URL, but not a 'get the tags from this URL and apply them somewhere else'.

My current prototype for fetching tags as suggestions for files from individual booru URLs is the 'file lookup script' system, which you can turn on for tag suggestions and can do some iqdb stuff. I was never really happy with the first version of this, but when I update and expand it in future, it would be nice to just be able to say 'hey, grab tags from this URL and stick them on the clipboard' kind of thing.

I will keep this in mind.

Any plans to add a pixel-identical deduplication system? As in, if a duplicate is detected with the "outline fuzzy matching" system then render out the jpeg or bitmap or whatever the file is for each potential duplicate to an array of ARGB and diff it, and if there's no differences run the normal "duplicates of equal quality" operation?

I understand Hydrus can't compare two jpegs to see which one is better, and that if the files aren't exact matches then a human needs to be in the loop somewhere, but I keep running into duplicate photos which have been compressed or had metadata stripped vs the original while in the comparison tool and can't help but feel that comparing identical arrays of bytes should be the computer's job.

There's already a detection algorithm for pixel identical pics, but there's no way to go through them outside the generic duplicate processing thing.
It'd be nice to have some set all pixel duplicates as better based on X/set all pixel duplicates as better based on X and delete option, with X being smaller size, number of tags, or some other parameter.

Hey, I am sorry, some of these options are ending up in disparate locations as I add them incrementally. I should go through all this search/tag shit and unify it to the same location.

To change the default file/tag domains for manage tags window autocompletes, hit tags->manage tags display and search, and then select the specific tag service.

That 'default tag service in search pages' governs the tag domain in autocompletes when you open a search page for finding files. It is normally 'all known tags', but you can set it to 'my tags' or something by default. I need to rename and tooltip all this shit, sorry for the trouble.

This is me, forgot which site I was on.

I want to add a pixel duplicate cache to the database and let you queue up these easy decisions differently in the dupe filter. At the moment, I calculate that on the fly when each pair is loaded, so I can't search for it, so I just have to write a maintenance task for it (and also do some ICC colour profile detection stuff to weed out this special false positive case).

The pixel-duplicate queue will be the first place where I try out automatic duplicate resolution. It will be completely optional, but you'll be able to set 'if a png and a jpeg are exactly the same, say the jpeg is better and delete the png', and it'll activate even on file import with a nice import status to reflect it.

Once we have db cache and automatic decision tech prototyped, we can explore automatic high-confidence jpeg quality comparison too.

I expect dupe improvements to do well on the 'big work' poll I'll put up for Christmas.

I haven't used Hydrus in about a year, just coming back now.

/help/getting_started_files.html states this:
>If you want to do private sexy slideshows of your shy wife, that's great, but think twice before you upload files or tags anywhere, particularly as you learn. It is impossible to contain leaks of private information.
Just curious, I read hydrus uploads no *files* anywhere right? It's all hash based? So no pictures or videos are actually being uploaded EVER (no matter which options you select).
Uploads are JUST matching hashes 200% of the time correct? This is what I inferred from the page.
Just wanted to ensure I understand this.

Also is there a way to disable a tag from being uploaded to the PTR? For example if I wanted to tag a bunch of stuff or an import so I can sort through it locally easier, but it would make no sense in the PTR, I can choose not to have it uploaded/blacklist it from being uploaded?

Not yet. Best way for now is to load up the search you want to do the big job on with a 'system:limit=4096' or similar, and then do it in manageable chunks.

You can take that limit off if you want. Just clear the rule for the PTR service under network->data->review bandwidth usage.

I think the new default rule is 512MB. It doesn't matter for existing users, and the guy who runs the PTR wants it removed completely, but I still need it for new users for now because of a maintenance initialisation issue. I don't want people processing 2GB of data before first round of idle maintenance kicks in.

It shouldn't matter once you are synced, as most update days are far less than the limits, it just spreads out initial sync over a more easily digestible duration.

For your hashes question, yes, files are not uploaded when you add tags, just hashes. I will never upload anything unless you specifically say it. The theory behind the shy wife scenario is you tag a whole bunch of stuff in the PTR, sharing that with thousands of anons, and then years later the images leak and some lad looks them up and see you helpfully tagged them all with name info.

A client by default comes with a 'my tags' tag service that is local only. You can create more local tag services under services->manage services as well. Any time you enter tags or set up tags to be added with a download using tag import options, you should see 'my tags' listed beside 'PTR' and any other tag services. Those are the different partitions you are putting tags into. 'My tags' is completely private, 'PTR' is shared with everyone.

If you want to add 'favourite' or 'process these wallpapers later' tags, put them in a local tag service like 'my tags'. PTR is best for booru-style tags, entered manually or via a downloader and tag import options.

I have to do more work on my end before apps can be more user friendly, unfortunately. It will come in time.

There's an annoying issue with Qt tabs and the way I rename tabs according to file count. More info in options->gui pages. Best solution, although it sucks, is to have nested 'page of pages' (e.g. "subs a-m" "subs n-z") and just multiple rows of page tabs that don't make the scroll arrows.

Yeah, you can do some neat auto-importing under file->import/export folders->manage import folders.

Hydrus can't do much uploading at the moment, but if you have another tool that can pull from a folder and auto-upload from there, then perhaps an 'export folder' under the same menu could do the job for you.

Two Questions:

1) Are tags with spaces, automatically recognized as tags with underscores too? For example, when managing siblings, if the parent is just as a rough example 'armpit hair', and I wanted to add 'hairy armpits' as a sibling, does this also mean I need to add 'hairy_armpits'?
It seems like I do by looking at siblings, some have underscores, some have spaces.

2) Managing tag siblings area is kinda confusing. The docs look out of date.
So if I were to add the tags in my first question, how should this be done?

I right click a tag, click 'add siblings to armpit hair'
and I am presented with this dialog (pic).

So if I want to add two siblings, it looks like I need to do so on the bottom right? But it only lets me add one, if I add a second, it just replaces what shows up.

If I type 'hairy armpits' in the bottom right box, then click add in the top right, it then asks to enter a reason for armpit hair->hairy armpits.

This makes it seem like, it's trying to replace the parent tag of 'armpit hair' to be 'hairy armpits', which is not my goal. My goal is to add 'hairy armpits' as a sibling.

I am a bit confused on these dialogs. They're labeled kinda unclear to me.

If you go to network -> data -> cookies you can create a pixiv cookie and then copy your login info from your browser(F12 -> application -> cookies on chrome). I think all you need is the PHPSESSID and __cfduid. I'm not sure if there's a way to log in through the companion.
A parser is what looks at the code in a page and takes stuff out like links and text.
Take this page for example https://gelbooru.com/index.php?page=post&s=view&id=5825934
If you press f12 you can see the html code that the page is build from. If you download that page through hydrus the parser will look at the html it receives from that page to detect the link for the image it should download and the text it should interpret as tags for that image.
The PTR is just a centralized repo for the tags. The PTR tags themselves are saved on your computer.
It is a single point of failure, but due to the offline nature of the data it isn't that bad.
There's file relationships like alternates and custom ones, but I don't think there's a good way to have before/after relationships that way.
There's the page: and title: namespaces which are sometimes used in the PTR though. Those are pretty useful for image sets and mangos.

The plan to move to Endchan only has changed!

Sorry for the sudden change, this all came together this week!

Codexx on 8chan.moe has kindly offered to host me on /t/ over there. As I have never been a comfortable BO, this is a much better solution for me as the primary place to talk Anon about hydrus.

I will be maintaining a Hydrus Network General, the first instance is here: https://8chan.moe/t/res/2219.html

The links in the release tomorrow will reflect this. Endchan will remain as a bunker.

Hmm, I am not sure. Perhaps the API the downloader uses puts private URLs in a different location, even if they are now technically accessible. I am afraid I do not know much about the current state of pixiv parsing.

If this is a one-shot job, you might have luck messing around with either extracting your private faves' URLs as a list using your browsers developer tools, and then pasting them all in to a hydrus URL downloader page, or if you are ok trying out some simple hydrus parsing, perhaps you can figure out a way to autoparse that with a 'simple downloader' page and its very simple 'parsing formulae' to do the same job of just ripping a list of URLs the client is otherwise ok to download. Then you would just be pasting a bunch of 'private fave' gallery pages into the simple downloader page.

1) I have somewhat recently started treating 'blue_eyes' and 'blue eyes' as the same when you type in tags for tag autocomplete results--if you type either, you will get results for both--but they are different tags in hydrus. If there are a bunch of 'hairy_armpits' results beside 'hairy armpits', you will want to sibling them if you want to merge.

The same is true for some other punctuation characters. '[intensifies]' is the same as 'intensifies', etc... But these rules only apply to searching for tag autocomplete results, not files.

As the sibling system matures, I expect I will write a 'just merge all underscores into whitespace m8' master checkbox somewhere. I am someone who would prefer things this way in my own client, essentially banning an underscore from being in a tag, but a number of users prefer strongly to have underscores available.

2)Yes, unfortunately I just finished a large round of reworks to siblings and parents at the end of last year. Some things work much nicer, but the edit workflows are still bad and the docs are out of date. I will keep working on it and parents this year. At some point I want to do away with the hellish pair system and have some nice graph UI that you can just drag and drop arrows around, but that is still a dream.

In that dialog, any tag on the left will be replaced by that on the right. Since tags can only be replaced by one tag, you can have a bunch on the left, but only one on the right. Often in the program and help I write a shorthand style or UI pattern of "A->B", which means 'tag A siblinged to tag B' or 'tag A should appear as tag B in the UI'. If you want 'hairy armpits' to appear as 'armpit hair', put 'hairy armpits' on the left, and 'armpit hair' on the right.

I should update that 'add siblings' text label to be something like 'make this tag appear as something else with siblings'. What do you think would be a good label?

I am also likely to rename the siblings and parents systems. This has been an ongoing discussion. Many boorus use 'alias' and 'implication', which I like much more, and is less confusing.

Still a bit confused still on the tag siblings thing.
If I type 'armpit hair' on the left dialog, it shows all the aliases at the top.
So if I want to add two siblings to 'armpit hair', lets say 'hairy armpits' and 'hairy_armpits' just as an example, I would type one of these on the right box, then click the add button, then ok on the popup.

Then I would do this again?

It doesn't seem like I can just say to make both of those a sibling in one go.

If I remove 'armpit hair' from the left, the siblings go away above, so it seems like that should be there.

The left is the parent, the right is where you type a desired sibling correct?


Typed that before I tried it, just tried it and it looked like what I just did replaced 'armpit hair' with 'hairy_armpits' which was not my intention although I submitted it. Not sure but I would suggest denying that change that I submitted to the PTR lmao sorry.

So yeah I'm very confused still.

When adding a tag to multiple files using the tag manager, it asks to either pend or petition the tag to the files.

What exactly is the difference?
I always clicked pend, I thought it was like append, but I just looked at the definition and it says "to remain undecided or unsettled. to hang." lol. So I was using that wrong I think

Does this mean all the tags I pended applied to the files, but won't go to the PTR?

Or does this only mean, they will only be local, until Hydrus runs the commit to PTR scheduler?
Where as if I petitioned them, they'd go directly to the PTR for review?

Didn't find any area on the docs that literally just explained those two buttons and what they did. I would suggest making that clearer.

Is it possible to remote control Hydrus from another computer running Hydrus?

For example, if I install Hydrus on computer 2, Hydrus 1 would be the host. If I'm on computer 2, I could pass links to have them download on Hydrus 1, I could also view all images and search stuff from Hydrus 1 on Hydrus 2.

It'd essentially be connecting to Hydrus 1, from Hydrus 2.
Nothing gets downloaded on Hydrus 2, it just is a remote control for Hydrus 1.

I know you can use the API for stuff like this, but I couldn't figure out if I can connect to the API from another Hydrus Network install. Not seeing where I would do that.

Hey, I am sorry, catching up after a long delay.

Not yet. Some network job controls let you override error delay from the little cog icon, but there's a domain-level block I have hardcoded atm. Ultimately, I will expose that system in some new UI to govern current domain status across the program and let you reset it.

I would like to maintain a bunker for those who are uncomfortable. I hope we can keep talking here.

I have improved some of the UI labels on this dialog. I hope it is more obvious now. basically you put the 'bad' tag(s) on the left, and the 'good' tag on the right.

The list at the top is what is currently stored in your database. When as you enter tags in the bottom, either side, the UI shows what those are already involved in, so you can see if you are overwriting or joining existing relationships.

One of these days I will carve out a few months to write the whole thing and have drag and drop networks of arrows.

Anonymous 02/20/2021 (Sat) 20:16:58 Id: eac545 [Preview] No.992 del
Hey, I think we already spoke elsewhere. If not, there is no way to do this en masse. But if you just have one or two parent relationships to change, just enter in what you actually want, and the dialog should say like 'hey, this conflicts with what is already stored, do you want to overwrite?', and if you hit yes, it will automatically petition for the old stuff to be deleted.

If you are on an HDD, unfortunately yes. I do not recommend syncing to the PTR on an HDD any more. There are just too many tags. About a billion mappings in the current PTR, which is ~42GB of complicated data on your drive.

If you are on an SSD, most users get around 1,000 to 5,000 rows a second once they are synced. You should see peaks of 50,000+ when you are earlier in sync.

If you are only getting 100 rows a second or similar, please pause your sync. If you are on an HDD, I recommend you pause it permanently and resume whenever you next update your hardware. If you are on SSD with those kinds of speeds, please let me know. Sending me some profiles as under help->debug->profile modes would be helpful so I can see what is going on.

Thank you, I believe this is now fixed. It turns out before '6+girls' was only working when it was mixed with other tags in a multi-tag query. Let me know if you still have trouble.

Anonymous 02/20/2021 (Sat) 20:27:22 Id: eac545 [Preview] No.993 del
I do not know much about this myself, but I think this is the current guide:

If you did that and it still doesn't work, I guess hit network->data->review session cookies and then clear everything and try again.

In hydrus, pend is add, petition is remove. Let's say you open a manage tags dialog on 10 files, 6 of which have 'character:samus aran'. You then double-click that tag. You then have the options:

pend samus to 4 (add that tag to the other four that don't have it yet)
petition samus from 6 (remove it from the six that do have it)

The terms 'pend' and 'petition' are different from 'add' and 'delete', yeah, because when you are talking to the PTR, all changes you make wait in the 'pending' menu up top. They only actually become 'real' when you commit by uploading to the server. You get the little (+) and (-) symbols after the tags, meaning they are 'waiting' to be added/deleted.

Thank you, I will clean up the help on this, and the UI.

Encryption is notoriously difficult to get right. I am not confident I can do as good a job as third party programs, so I strongly recommend you figure out a solution using one of them. Hydrus works completely fine out of a mounted encrypted partition as ciphershed-style software will create.

Syncing to a remote server is not as simple in this situation, but perhaps a program that encrypts individual files would fit into your workflow. Or if your remote connection is secure, and the client and server are also operating out of encrypted containers you trust, it may work.

It is generally not safe to touch the database file while the client is running. I know google-cloud backup has corrupted a hydrus database it was watching. I recommend you only do backups while the client is shut down.

Anonymous 02/20/2021 (Sat) 20:33:05 Id: eac545 [Preview] No.994 del
Are you synced with the PTR? That makes your four client.db files about 40-50GB now. The internal backup is basically just a copy of your 'install_dir/db' folder, which is:

The four client*.db files.
256 'fxx' file folders under 'client_files' folder
256 'txx' thumbnail folders under 'client_files' folder

Not much yet. Everything at the moment is here:


You can queue up URLs for download and fetch simple searches back, and files/thumbnails.

I hope to keep expanding it, including eventual full session control so you can make new pages and so on.

Giving them new names should do it. The basic 'new defaults' overwrite I use in my update (whenever I say 'rolled in a new blahbooru url class' in a changelog) works on name.

Yep, mostly you just have to wait for sync. It'll take a couple of weeks, and you need to have an SSD with 50GB of space. As long as your files are 'popular', the same as those stored on the big boorus and other gallery sites, you'll see the tags given to them by other anons on hydrus.

you can manually save a session of your pages, which can then be appended to an existing session if you accidentally close that tab. see the 'pages' menu -> 'sessions.'

making this automatic is already implemented in two ways:
- there's session restore, and a decent history of previous sessions saved.
- the 'undo' menu. you can reopen a closed tab within the same client session.

does reopening that page from the undo menu not preserve the tab's configuration for for a watched thread page? is that what you're asking for being improved?

I'm confused on your reply here, you're saying it IS possible to use Hydrus Network client on a second computer to remote control it's just limited?

I am familiar with the client api, as I am using Lolisnatcher Droid with Hydrus for mobile.

My question is basically, where do I go to input the client api information on the secondary Hydrus Network client.
And how does it grab the pages? Do I just go to new page, and choose files and search and it pulls everything from my other Hydrus client?

I'm just confused on the setup on the remote machine when using Hydrus Network client.

Also unrelated, but if I may suggest adding Nginx example configurations to the Hydrus docs.

Hydrus is extremely bloated, I think it would be amazing to see it come with the bare minimum, then allow users to add on whatever features they want.
This would allow for better security, better performance, less bloat, and I would imagine a bit easier to maintain and focus on stuff individually during development.

On a sidenote, is it possible to move the PTR to one drive, but keep hydrus and the db on another? I see no options to select ptr location.

I also think the docs need a major revision, and a search box.

I don't mean set rsync on the entire database directory.

I mean in Hydrus when you "update database backup", it backs it up to a separate folder of choice. So it's syncing the folder hydrus backs up the db to, not the hydrus db itself.

Is it safe to set rsync on the folder hydrus backs up to is my question?

secondly, i'm not sure how im supposed to actually connect to this from another machine locally, am i expected to just my OS's native network share function and just have sort of a shared installation across machines accessing my hydrus locally?

I was hoping for htis to be an easy way to access and manage all my images across PCs

i've been using the PTR for a while, and most of the tagging I've done has been done in the PTR rather than my tags. but i think the PTR is taking up too much space on my SSD

if i use "migrate tags" with the default settings, can i copy the PTR tags to the local my tags for JUST the files that I currently have, so that I can remove the PTR without losing all the tagging I've done up till now?

The e621 login script seems to be half-broken: when trying to login it consistently gets blocked by cloudflare, but when testing it on the "edit login script" page it works perfectly.
This happens even on the same IP, and with less than a minute between both tests.
Anyone has a clue as to what might be causing this difference?

when using stuff like "collect by title" in the search page, is it possible to sort by random for the overall results page but sort by page number within the individual collection?

e.g. say I have a few titled image sets with red_hair tag, with 2-10 images in each. when I sort by random I would like to see a random image set, but then as I scroll through the page I want to see page 1, page 2, page 3 etc from that image set. right now, if I sort by random and group by title, I will see pages in a random order like 6,10,4,1,9, etc

Is there way for nitter importer to apply post date as file metadata date and if it is possible for multiple images in one tweet to have relationship between each other?

How could I set Hydrus to download the entirety of e621? I'm new to Hydrus but want to backup the site due to how much seems to get removed from it
