Editor writes inserted text to different in-file location than displayed

[dr-1]

When editing a file with the integrated editor, new text occasionally gets written somewhere else in the file than what is shown on screen. For example, when I add a function to the end of a script it may actually be written further up in the file, in the middle of a line, as confirmed by viewing the file in other editors. The JupyterLab editor will show the new text in the intended location even after closing and re-opening the file.

I am not able to reproduce this behavior but notice it crops up from time to time. Perhaps others have more insight into when and why this happens.

Hi @dr-1, we have heard of this happening one other time, but we weren't able to track down the cause.

• What version of JupyterLab?
• Were you using the google-drive extension?
• What kind of file were you editing?
• Were you viewing it in more than one pane (such as Markdown Preview or New View into File)?

If it happens again, can you open your browser's JavaScript console and look for any errors? We added this debug output in light of the last report.

[dr-1]

When it happened yesterday I was editing a Python script

• with JupyterLab 0.27.0
• in Google Chrome 60.0.3112.113
• on Ubuntu 17.04

No google-drive extension. The file was open in one pane only. I had several other editor tabs open to edit other files, as well as a notebook pane to run the script.

I will keep an eye on it and check the output in the JavaScript console.

Experienced the same issue here:

• Jupyter Lab alpha release version: 0.27.0
• Windows 10
• Firefox 55.0.3 (32-bit)

running within virtual env with Python 3.5.3

I still haven't been able to reproduce, but https://github.com/jupyterlab/jupyterlab/pull/2967 makes it easier to report when something goes wrong.

Hope this helps!!

Hi @aeroaks, can you please paste those file contents here (or paste a link) so I can try them?

Progress, thanks @aeroaks! It looks like a line endings issue. I reproduce the error on Windows 10 by making sure the above file has CRLF line endings.

[blink1073]

Although it does not explain the error happening on Linux, which should have the LF endings that CodeMirror expects.

[sccolbert]

A file on linux can still have CRLF endings, especially if its from a git repo with multiple contributors.

[dr-1]

I can confirm the line ending issue. On Linux, when I convert line endings of a file to CRLF and then edit it in the JupyterLab editor, the error occurs and Chrome's JavaScript console shows the "Uh oh, the string model is out of sync:" error message.

[timvink]

I have the same issue. Lines are 'scrambled' after saving + reopening text file in JupyterLab.

• JupyterLab 0.27.0
• Google Chrome 60.0.3112.78
• Red Hat Enterprise Linux Server release 7.2

I was able to fully resolve the problem by removing windows line endings (^M) with:

sed -i 's/^M$//' <filename> # for the special ^M char, use CTRL+V then CTRL+M

Must have something to do with special characters. I somehow got a bunch of hidden delete characters in my cells. When I would try to run and it errors out with the syntax error it shows missing characters where the errors is. I cut and paste as plain text and the issue goes away.

Hi @megamindbrian, do you have the original file? If you save it as TXT, you can drop it into the comment box here.

[ghost]

interpret questions.txt

[blink1073]

Thanks! However, I wasn't able to reproduce the bug with that file. What version of JupyterLab, and which OS and browser are you using?

[ghost]

Using Windows and Mac. Windows line endings are \n\r and Mac is just \r This popup is so awful doing some reformatting I might have to switch editors.

[ghost]

I take that back. Doing a find and replace for \r", and replacing \n", appears to have worked.

[theloni-monk]

I'm on windows 10 using the latest version of Chrome with the lastest Jupyter Lab version

and I just ran into the same issue while editing a python file, but doing the find and replace did not fix it.

[ghost]

I realized there are more find and replaces, "\r" with "\n", or \r\n" with \n". I didn't run into any problems editing .ipynb files directly, but if it doesn't open you may want to repair it by changing the extension to .json. Make backups.

I am pretty convinced it has something to do with the \r character. It started to clear up once they were all removed.

I think you are right, I just restarted my computer, and replaced all the \r with \n, and the code appears to be behaving normally after editing.

For those that saw this recently, can you try with the latest prerelease, 1.0a3, and see if it is still an issue. It should have been fixed in 1.0a0.

What version of JupyterLab do you have?

[kellington]

jupyter --version 4.4.0

jupyter lab --version 0.32.1

jupyter notebook --version 5.4.0

[kellington]

Jason - unfortunately, I can't recreate it right now - I deleted the notebook I was working - wasn't thinking it would be useful.

[jasongrout]

jupyter lab --version 0.32.1

That is a very old version of JupyterLab at this point. This issue should have been fixed in newer versions. I'd suggest upgrading to 0.35.x.

[jasongrout]

Actually, looking at the PR that fixed this issue above, this was fixed in 1.0a1. I'd suggest upgrading to 1.0a3 if you can, or waiting until 1.0 (which should be fairly soon).

[wongjoel]

I realize this issue is closed, but I was directed to this issue directly by an error message from running an ipython console in jupyter lab.

Browser console output below: from editor.js:888

Please paste the following to https://github.com/jupyterlab/jupyterlab/issues/2951

Steps taken to reproduce

1. Make a new text file with jupyter lab, rename to hello.py

   print("hello_world")

2. Open a python3 console in jupyer lab
3. Run %load hello.py

4. A pop up appears, with the message Code Editor out of Sync. Please open your browser JavaScript console for bug report instructions

Similar repro as described by @wongjoel: I just executed a \load (which is the equivalent for %load in this kernel) on a console. Executing \load in a notebook works fine

[TRM13]

---

Update: When I had these 3 lines in one code cell the third command would cause the problem. Once I put them all in their own cells it now works:

New-Item -ItemType Directory -Path "C:\Users\Administrator\Documents\WindowsPowershell" Set-Location C:\Users\Administrator\Documents\WindowsPowershell New-Item -ItemType file -force $profile

If I run them all on one line separated by semi-colons it also works. It also runs fine if I put it in a PS1 script. Only when the 3 lines are in one cell does the "caching" happen and you have to run following cells twice to get the correct result.

---

Original: This may be related. I've run into this on Windows 10 (native), Server 2016 & 2019 (VMware WS 15), Firefox 68.0.1 (and Chrome and Brave). Runnng with Powershell kernel 0.0.7

In FF I've turned off all caching (devtools.cache.disabled = true; browser.cache.disk.enable = false; browser.cache.memory.enable = false)

When I hit a code cell with output that is long it seems to cache it and when I click the next code cell it outputs the previous cell's output. When I click the cell and run it a second time the output is then correct. Enabling cell scrolling did not fix it.

This behavior also occurs in the console but not the terminal.

When I look at the notebook file in Notepad++ it shows all the lines with "LF" not the "CR LF" I was expecting in windows but even changing that to "CR LF" did not fix the issue.

If you want the notebook for testing let me know.

I got this error today in JupyterLab version 3.1.4 with the following traceback, which I think might have been triggered by ctrl + z after I noticed that I lost one of my cells with important output (I figured I must have deleted it accidentally but it might have been a bug instead):

I hope that #10756 will fix this, but let's see nope, that fix is already in since 3.1.2, so that did not fix it. It could be also relevant to discussion in #10694.

[krassowski]

CC @hbcarlos and @dmonad on the above issue which seems to be a new addition to the repertoire; the traceback is coming from on of the non-null assertion operators in:

https://github.com/jupyterlab/jupyterlab/blob/21b3fdf053701368569736bce7661ad3925236fb/packages/shared-models/src/ymodels.ts#L553-L570

this is just FYI for now, I am not yet confident if the shared models are the culprit or just a first place that gets kicked after an actual error, but in any case it might be worth considering if we should use .? there.

I wrote some jupyter notebooks code in VS code and copied it to a unix server -- and got this message all the time. After some experimentation, it seemed that the literal "\r" (carriage returns) in the code was the culprit.

in.ipynb | sed 's/\\r//g' > out.ipynb

fixed the issue I was having. I see that "\r" appears in a number of comments above and that it was suggested that it was the culprit. I suggest changing the error message on jupyter from

Please paste the following to https://github.com/jupyterlab/jupyterlab/issues/2951

to

Please remove all instances of \r in your code.

Or something like that. Or just fix the bug?
