Vscode-jupyter: In a notebook (.ipynb file) paste double pastes.

[ddouglas87]

Issue Type: Bug

If I copy text from one cell and paste into another cell it double pastes.

If I cmd+z to undo it undoes one of the two pastes implying the issue is pasting. In .ipynb files, VSC double pastes.

I tried pasting in a .py file with no issue. Likewise pasting in the issue reporter has no issue, just in Jupyter Notebook cells.

I manually restarted VSC and the issue went away. After a while (12 minutes of use) the issue randomly came back when pasting between different notebooks.

The issue seems intermittent coming and going seemingly randomly.

VS Code version: Code 1.45.0 (d69a79b73808559a91206d73d7717ff5f798f23c, 2020-05-07T15:57:33.467Z)

I just came here to report this and I saw this.
I have the exact same OS and VSCode version and I see the exact same issue, as perfectly described by @ddouglas87

[juanitorduz]

Exact same here.

[DonJayamanne]

Thanks for reporting this issue.
This is odd, I understand this is intermittent, but would appreciate some help trying to repro this so we can try to trace the underlying issue at our end.

Please could you:

• Provide output from console window:
  
  
  
  • Open Developer: Toggle Developer Tools
  
  
  • Go into console tab
  
  
  • Provide all of the contents from the console window. (i.e. past into this issue).
  
  
  • Please do this when you come across the bug
  
  
• Please could you try reverting to the previous version of the extension to confirm it works
• Please could you try reverting to an older version of VS Code (1.44) & confirm it works
  
  
  
  • Recently we may have identified a regression caused by the latest update to VSCode itself, though not sure how it could impact this.
  
  
• Any other information/steps that u think might be useful in repro-ing this issue.
  
  
  
  • When u are pasting into a cell, are you in the middle of a cell execution?
  
  
  • Are you pasting into a new cell or existing cell (i.e. pasting over something else)?
  
  

[ddouglas87]

Toggle Developer Tools is under the Help menu drop down, not Developer.

Provide all of the contents from the console window. (i.e. past into this issue).

Here is a paste of the console. It's a lot of text. The double paste happened May 14th at 11:13am. I grabbed a copy of the console (ctrl+a, ctrl+c) seconds after it happened.

Please could you try reverting to the previous version of the extension to confirm it works

I don't know how to do this.

Please could you try reverting to an older version of VS Code (1.44) & confirm it works

This issue is brand new to the newest VS Code. To verify, I do not know how to revert to an older version. I'm sure someone else will verify this though.

Any other information/steps that u think might be useful in repro-ing this issue.

When u are pasting into a cell, are you in the middle of a cell execution?
Are you pasting into a new cell or existing cell (i.e. pasting over something else)?

Both. It happens randomly in the middle of cells and in new cells. It has to do with pasting into cells, any cell.

When doing a cmd+v into a cell CSV reads it as two cmd+Vs being pressed, which is why cmd+z will undo one of the two pastes.

Because it is intermittent it might be a race issue?

[greazer]

Looks like a possible regression.

[DonJayamanne]

@ddouglas87 Thanks for providing the information.
Unfortunately I'm unable to replicate this at our end and cannot find anything in the logs.

This issue is brand new to the newest VS Code. To verify, I do not know how to revert to an older version. I'm sure someone else will verify this though.

You can go to their releases page, see here https://code.visualstudio.com/updates/v1_44

Please let me know if it repros.

[greazer]

@ddouglas87, please follow Don's suggestion on installing an older version of VS Code to see if the problem is dependent on the latest build. Please let us know if the problem no longer repro's in 1.44 but does in the latest. If it repro's in the older version, then any additional details you can provide to help us reproduce the problem would be ideal.

[santoshkumarradha]

Can confirm, experiencing same issue on the latest version.

[DavidKutu]

Same issue is happening to @Saafo, here is his info:

• Jupyter server running: Local
• Extension version: 2020.5.80290
• VS Code version: 1.45.1
• Setting python.jediEnabled: false
• Setting python.languageServer: Microsoft
• Python and/or Anaconda version: Python 3.7.7 & conda 4.8.3
• OS: Mac
• Virtual environment: conda

[jbeyer16]

Been experiencing the same thing (1.45.1). This is not the first version I've noticed it on. Not sure if the screen grab is helpful or not, but you can definitely see how it's intermittent. I only do CNTRL + C when you see the text highlighted. As you can see, it happens, then seems to also clear itself, but is not consistent across tabs. Although this example includes copy and paste across two notebooks, I've seen it in just one as well.

I had the dev console open while recording this, but nothing printed to the screen at any point while noticing the duplicate pasting.

[YashKarthik]

Same here I've been experiencing this issue for the past few days,
also now copy paste doesn't work :/,
will be opening an issue

[YashKarthik]

I just updated the extension and now it's back to normal

@YashKarthik which extension do you update?

[YashKarthik]

@danielaik I updated the entire python extension
I hadn't used vscode in a long time so the updates were pending for me.

[widovanheemstra]

This is still an issue for me. Copying between two locally saved notebooks on MacBook Pro causes still to paste the content twice.

I checked the python extension version, which I use daily (2020.06.88468 (16 June 2020))
And running VS Code 1.46 May 2020.

Update: If I select the contents of a cell, then click on an extension to see its information and then paste from clipboard, the contents is not duplicated. I know this is not a procedure that you would normally do, but performing an action in between prevents the duplication.
Switching the tabs on the left does the same.

Hello,

I also confirm having the same bug, I tried to check if it was linked with the "copy" or the "paste" process however it only happens when I paste content in a cell (it doesn't matter if it is from the cell or from outside of VS Code, when a cell is copied and pasted outside of a notebook, it works properly.

Sorry to add to your trouble but now this bug is also present in Python Interactive terminal!! No matter where I copy from it always pastes double. But this bug appeared very recently. Like in past few days. So I guess it may be related but not the same. So I'll open a new issue as well. 😉

@dimitry-ishenko
Thanks for the steps outlined in https://github.com/microsoft/vscode-python/issues/12731#issue-650190783
Unfortunately I'm unable to repro this issue. Are you still able to repro this consistently.
I.e. close VS Code open a notebook and check again.
Once again, thanks for the great steps, we're stuck at trying to repro this at our end.

[dimitry-ishenko]

@DonJayamanne thank you and correct, I can reproduce the issue with 100% "success" rate.

Here's another demo, which includes launching vscode, creating new blank notebook, entering foo bar baz, copying (Ctrl + C) and pasting it (Ctrl + V) with resulting double-paste:

[DonJayamanne]

@dimitry-ishenko
Thanks, I can replicate this, though its not easy.
Now I cannot replicate thsi, need to keep trying to get the timing right, there's clearly some issue with some timing.

Now I cannot replicate thsi, need to keep trying to get the timing right, there's clearly some issue with some timing.

Interesting... I don't have to do any sort of timing "tricks" to trigger this. It happens 100% of the time.

[DonJayamanne]

@dimitry-ishenko
Please could you try installing our current development/insider build of the extension.
You can do this by going into your command palette & selecting Python: Switch to Insiders Daily Channel.
This will download and install a new extension. Then go into your extensions list and you should see Python 2020.7.0-dev as the version of the extension.
YOu can always opt out of this later on by going into the settings and updating the setting Python: Insiders Channel to off

Please let met know how this goes. FYI - u will need to reload VS Code after the new extension has been installed.

[dimitry-ishenko]

@DonJayamanne sadly, that didn't help:

[DonJayamanne]

This is very frustrating, i can no longer replicate this.
@IanMatthewHuff @rchiodo @joyceerhl @DavidKutu Please could you check if you can replicate this.
I was able to replicate using the above video in VSC Stable & Stable extension. Now nothing.
The user can replicate this in insiders & latest insider version of extension as well.

[DavidKutu]

I was never able to repro this on Windows or Ubuntu, as far as I know it only happens on Mac.

[dimitry-ishenko]

@IanMatthewHuff @rchiodo @joyceerhl @DavidKutu to spare you some reading, I am on vscode-insiders:

Running Ubuntu 20.04.

I am using minimal amount of extensions:

Tried disabling all extensions other than Python - didn't help.

[IanMatthewHuff]

I don't think that I've seen it on Mac. But I have a Linux VM. Let me spin that up quick and look.

[j450h1]

I can confirm this issue on Mac OS Catalina for at least a few weeks and still ongoing. And I have the latest: Extension version: 2020.6.91350

[dimitry-ishenko]

I am also able to reproduce this issue on another Ubuntu 20.04 box:

[luabud]

I'm also reproducing it 100% of the time and I'm on Windows

[arachid1]

quick fix is to Control+Z on mac (cancel) which is gonna cancel the second paste.

[dimitry-ishenko]

@rchiodo if you are interested, I can bisect this at least on the version level to see which version this was introduced in.

[rchiodo]

@dimitry-ishenko if you don't mind, that would help. I'm unable to determine the root cause at the moment.

[dimitry-ishenko]

Executive summary:

• The above tests were done with python extension version v2020.7.92789-dev
• The bug seems to have been introduced by a change in vscode and not the python extension.
• Last "good" version of vscode-insiders: 1.47.0-1593413883, commit: 7923112cdd20575406ec547b55a99c289dd7d7e2
• First "bad" version of vscode-insiders: 1.47.0-1593495868, commit: da73d2d11540232a5c75788ac0c9b41c3d432b2d

Unfortunately, I've torn down my docker container for building vscode (and I am too lazy to set it up again), but with the above commit IDs one should be able to bisect further and figure out where the issue was introduced.

[dimitry-ishenko]

One thing of note is that between the good and the bad versions Electron was downgraded from 8.3.3 to 7.3.2.

This happened in commit 85402615934f3c8b97ad14d8c483383833287a82

[rchiodo]

Thanks @dimitry-ishenko. We might be able to use that to get VS code to fix this.

In the meantime we've implemented a workaround. Can you give it a try to see if it fixes the problem for you?
https://pvsc.blob.core.windows.net/extension-builds/ms-python-insiders.vsix

Thanks

[dimitry-ishenko]

@rchiodo thank you, it does handle the double-paste problem. :tada: However, another aspect of the problem, which I brought up in my original issue microsoft/vscode-python#12731 is still unresolved.

Watch me perform copy/paste below, which works as expected and then cut the original line:

The pasted line below it falls into the abyss.

Should I open a separate issue for this? Or maybe modify and reopen my original issue?

[rchiodo]

That looks like a similar problem for cut. It's double cutting. Blech. We should attempt to repro this with a simple example in a VS code webview (not our python one). Then we can log this on VS code and get them to fix it.

Thanks @dimitry-ishenko. Can you open another bug for the double cut? It's the same thing but we can start there and try to create a repro for VS code.

This worked for me too for now. Started having the problem after closing the window and letting the new release to come. Good workaround until the bug is fixed.

Additionally, after doing 'Ctrl + V' and getting the double paste, doing 'Ctrl+Z' removes the duplicated element, so the paste action is somehow done twice individually.

[aadityakapoor06]

I am facing this same issue of double pasting in the JUNE 2020 update, Version: 1.47. Please have a look at this asap, its quite annoying.

To re-iterate for people newly experiencing this problem: this happens because the paste command is triggered twice.

Your options are:

1. Press Ctrl + Z to undo the second paste.

2. Some users have reported that pressing Ctrl + Shft + V works well on Windows (haven't tested myself).

3. This has been fixed in the insiders version of vscode. You can upgrade if you feel adventurous :smile:

[tasilva96]

Ctrl + Shft + V worked on Ubuntu. Thanks.

[visini]

I have the same issue but also noticed that undoing after I pasted would randomly jump between cells.

This is an issue which I'm experiencing too. In the past few versions, I had to rewrite cells entirely due to inconsistencies in undo/redo, which randomly triggered "undos" with strange fragmented data from my clipboard history and/or from other cells "undo" state, leaving the whole cell corrupted. Extremely hard to reproduce, since it happens only once or twice every few hours, but annoying still... I too am suspecting the undo/redo bug is related to this issue.

@visini I've seen this one as well. Agreed very confusing because it's not exactly clear where the "undo/redo" text ends up coming from. Also agree very hard to reproduce - thankfully rare. Curious to see if this fix in 1.48 will prevent it entirely or not.

[EricChen1248]

does anyone know what the editor.action.clipboardpasteaction actually does? That seems to be the problem. It's default registered to 2 keybinds "Ctrl + V" and "Shift + Insert" both of which causes the double pasting behaviour here.

Removing the "Ctrl + V" keybinding fixes the issue for me, and I have yet to notice where the removal of this keybind causes any difference elsewhere.

[lixm1121]

Issue Type: Bug

If I copy text from one cell and paste into another cell it double pastes.

If I cmd+z to undo it undoes one of the two pastes implying the issue is pasting. In .ipynb files, VSC double pastes.

I tried pasting in a .py file with no issue. Likewise pasting in the issue reporter has no issue, just in Jupyter Notebook cells.

I manually restarted VSC and the issue went away. After a while (12 minutes of use) the issue randomly came back when pasting between different notebooks.

The issue seems intermittent coming and going seemingly randomly.

Solved, and delete ctrl+x keybinding for editor.action.clipboardCutAction solve double cut problem too.
But I guess after devs fix this bug we need to take these keybinding back?

[lucas-hattori-costa]

does anyone know what the editor.action.clipboardpasteaction actually does? That seems to be the problem. It's default registered to 2 keybinds "Ctrl + V" and "Shift + Insert" both of which causes the double pasting behaviour here.

Removing the "Ctrl + V" keybinding fixes the issue for me, and I have yet to notice where the removal of this keybind causes any difference elsewhere.

Solved for me as well

[akshitgupta29]

Not only in insiders version, but this is also there in the stable version 1.47 as well

This is Instant Solution about this issue.

Details:

1. Go to [Keyboard Shortcut] Menu (Ctrl+K Ctrl+S)
2. Search
   
   
   
   • editor.action.clipboardCutAction
   
   
   • editor.action.clipboardCopyAction
   
   
   • editor.action.clipboardPasteAction
   
   
   • If the actions above are bind by "Ctrl+X", "Ctrl+C", "Ctrl+V", remove that binds.
   
   

Good Luck to all :D

This fixed the double paste issue but I still get an undo issue where undoing a large paste will only undo half and ends it with ellipses (...)

[dlefcoe]

From Keyboard Shortcuts in VScode.

search for: editor.action.clipboardPasteAction
remove the CTRL+V keybinding.

This works in Windows 10

VScode version: 1.47.1 (installed in 2020)

I also still had issues with Undo (Ctrl + Z) after removing the bindings for Ctrl + V. I simply removed the bindings for Ctrl + Z as well and that seems to have fixed it. In my case, there were two bindings of which one specific to notebooks, I removed both of them.

[luismsalazare]

I can confirm that Ctrl + Shift + V is a workaround in Windows 10 too.
Context: I got this issue after I opened Python Interactive Window for the first time (although previously I worked with Jupyter notebooks in VS code smoothly, without this error).

Good tip. Thanks!!

[marianatuma]

I'm having this issue with other commands as well, like Ctrl+x, Shift+delete, etc. Rebinding them works, but I thought it was worth it to add it here.

[kjohnsen]

I'm having the same problem with both cutting and pasting. That is, Ctrl+X cuts two lines, and Ctrl+V pastes twice.

[blucifer22]

Same problem here.

[haduong83]

Same here even for windows 10. And that only happens to a notebook

search for: editor.action.clipboardPasteAction
remove the CTRL+V keybinding.

This solution works for me too.

[clone95]

@EricChen1248 I love you <3 It worked like charm!

[udaykapur]

Came here to report this exact issue and found this thread - issue still exists without the workaround of removing key bindings posted above.

Using VS Code 1.47.1 on Win10 Pro

Thank you so much for the help @amaruak00 . It worked Perfectly

[JSym]

yep, removing the ctrl+v keybind on editor.action.clipboardPasteAction worked for me too. thanks @EricChen1248

I misunderstood this at first, so to make it clear:
For some reason removing the keybindings still leaves them functional,
it only avoids the bug.

Encounter same bug. Removing the ctrl+v keybind works in Mint 20, vs code 1.47.1 too.

[kyyky]

Suggest use Ctrl+Z after paste for this stage -_-

[marc-rauckhorst]

Unfortunately, the solution from @EricChen1248 does not work for me. Unlike others, removing the keybindings does not leave them functional, and remapping them produces the same doubled behavior for both cutting and pasting.

The oddest part of all of this is that the behavior is so intermittent. It's definitely triggered by copy/cut-pasting from one notebook to another (regardless of the kernel from what I can tell) but doesn't happen every time and will sometimes go away for a while only to come back later.

I'm not having this problem in 1.47.2.

[mcmar]

Don't want to add spam here, but because someone commented above about a potentially fixed version, I feel that I need to add that I'm still having this issue on 1.47.3. I've also observed this issue intermittently with no obvious cause, so I'd have to guess that the above person simply had a lucky day.

Shortcuts affected: ctrl-x, ctrl-v
I'm not sure about ctrl-c because it's idempotent, so it doesn't really matter.

And now ctrl+c copy word not working inside cell, also. Can' t believe how could developers use this?

[rebornix]

Can anyone try the latest Insiders (built yesterday) https://code.visualstudio.com/insiders/ and see if you still see such problem? It's going to be the stable release so want to confirm that the problems you are seeing here are resolved.

Funny enough, in my case, I had to add editor.action.clipboardCutAction and editor.action.clipboardCopyAction key bindings as they were not set. There was no editor.action.clipboardPasteAction nor any other Paste action worked.
After these two were set, I can cut and copy texts in .ipynb files.
Use Ctrl+Shift+V for pasting (no setting needed). I'm using Python extension on coder.com's code-server

The keybindings stopped being functional.

Does this mean the underlying problem has been fixed?
