snowtimeglass commented 2 years ago

Thank you always, developers.

Reproduction Steps

(In short, answer with "HARD" button, then display "Card info" of the card.)

  1. Display a card on Study screen
  2. Tap "SHOW ANSWER" button
  3. Tap "HARD" button test 3 half
  4. Tap "≡" button (Open Drawer)
  5. Tab "Card browser"
  6. Longtap the row of the card (then the row is selected)
  7. Tap "⁝" button, then tap "Card info"
Expected Result

The interval written in the study row is consistent with the one written in the "HARD" button.

Actual Result

The interval written in the study row is inconsistent with the one written in the "HARD" button. image

Long time no see @snowtimeglass :-), thanks as always for a thorough bug report. Now if only you would log things that looked easier to fix ;-)

david-allison commented 2 years ago

What does Anki Desktop show here (for the same cards)?

snowtimeglass commented 2 years ago

Long time no see @mikehardy @david-allison :-), thank you so much for the wonderful progress.

@mikehardy

Excuse me, but I'm not sure what you meant. Did you mean that if only more information would be added? :-)

@david-allison

What does Anki Desktop show here (for the same cards)?

I should have specified that point. Anki Desktop shows consistent intervals properly. Examples (of Anki Desktop and AnkiDroid) are as follows. They are the results of the third study of the above sample card.

I'm not sure what you meant

I just meant scheduler bugs are usually hard! Much easier when something is just the wrong color. But better to know there is a problem then not, of course, I was just joking and always appreciate the reports

snowtimeglass commented 2 years ago

Thanks. I was not so sure of that, but felt you were just joking, so please don't worry :-) I always appreciate your arduous work, too.

david-allison commented 2 years ago

Thanks so much, so it appears to be a display bug in CardInfo.

This is a massive relief: this implies a bug in some quick code that I wrote, rather than a bug in the scheduler. We will be replacing CardInfo entirely with Rust.

snowtimeglass commented 2 years ago

Thanks, I'm glad to hear that :-)

By the way, I just now unexpectedly saw #7762 (a CardInfo topic) and remembered it. How about reopening it?

david-allison commented 2 years ago

Reopened! To be honest, I expect it'll go stale again, but more than happy for someone to pick it up as side work

In general, my plans are:

snowtimeglass commented 2 years ago

Thanks! I hope your plans will go well.

@david-allison can i work on this issue

@david-allison can i work on this issue

Yep! Thanks!!

@Prince-kushwaha, Are You Still Working On This Issue?

suman-somu commented 2 years ago

@david-allison @mikehardy I have a question related to this issue, I was working on this issue before it was assigned, and was checking for the possible errors in the main code. So I searched for possible errors in the "HARD" button part, as well as for the display part in the "card info". And the result, I didn't find any errors in both. In this process I found out that they were connected through the database (as per my knowledge, its referenced as this).

So, I know its possible that I might have missed the wrong code in the searched files, but is there a chance that the bug is in the database ?

suman-somu commented 2 years ago

@Arthur-Milchior , would you answer the previous question i.e. ...is there a chance that the bug is in the database ?

Arthur-Milchior commented 2 years ago

@suman-somu (if you are still interested) Essentially, we don't know. We didn't investigate in depth this bug, we had and still have more urgent things to do. The bug can be anywhere, in the database, in the scheduler code, in the display code. Discussion above concluded it was in the display code, so that's personally where I'd start looking. But if this analysis was wrong, you can do your own investigation and try to find why. In particular, you may want to learn how to read the database content directly, e.g. with sqlitebrowser on your computer, so that you can check the actual value and compare it to the displayed value. You may want also to use the same collection on anki and ankidroid, so they should have the same database content and this should allow to confirm whether the value displayed is different on both devices

suman-somu commented 2 years ago

Okay, I will go through it again thoroughly.

I have confirmed that this issue remains on 2.16alpha83, so please keep this open.

mikehardy commented 2 years ago

@snowtimeglass does this happen if you alter settings --> advanced --> enable new backend + enable v3 scheduler?

snowtimeglass commented 2 years ago

Ah, this doesn't happen in these settings! Thanks for the advise!

mikehardy commented 2 years ago

Okay - we are moving towards that as the default hopefully soon, so this may be considered a low priority in my opinion. If we fixed it, we would be working on code that will soon be deleted, so it is not worth a lot

snowtimeglass commented 2 years ago

Well noted :-)
