What job does vscode file watcher do? - visual-studio-code

I met error "Visual Studio Code is unable to watch for file changes in this large workspace" when I work on a remote server. The solution to this problem is here: https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc
As I do not have permission to edit /etc/sysctl.conf to increase the limit, I have to exclude some directories from file watcher. I wonder what job does vscode file watcher do, and what happens if certain files are not tracked by the file watcher? So far I think file watcher is not so important so it should be safe to exclude files from file watcher?

Unable to watch for file changes in this large workspace which has only two cpp files

I am trying to run the first example of zguide (zeromq). The project has two files, client and server, and I am doing this using vscode ssh remote on a RHEL7 machine.
Here is the structure of the folder and how it looks like in VSCode explorer:
ZEROMQ[SSH:remote_machine]
|_.vscode
|_tasks.json
|_c_cpp_properties.json
|_client.cpp
|_server.cpp
Once in a while I receive this warning:
Unable to watch for file changes in this large workspace folder. Please follow the instructions link to resolve this issue.
The instructions are of course telling me to increase the limit size which I don't think is the issue here with such a small project.
So, any ideas what's happening and how to resolve this?

Custom referenced file from launch.json for Visual Studio Code

we have a project in which there are a number of launch/debug options referenced in the top-level Visual Studio Code's .vscode/launch.json file.
The issue is that this file needs to be edited for custom local debug options so it constantly triggers Git issues when doing a pull (stash etc) and at worst, sometimes gets committed with changes people needed locally. Yes, I know that's what PRs are for but somehow they keep sneaking in...
Unfortunately there are plenty of entries in the launch.json that need to be shared between devs so ignoring it is not an option.
Ideally I'd like to keep launch.json clean and have it reference another file that devs can tinker with and keep that one out of source.
Is there a way to do this or maybe have an approach that amounts to the same thing?
thanks
with the extension Command Variable you can use the command extension.commandvariable.file.content to read parts of a file and use it in your launch config. You can place the file in your .vscode directory and place that file also in your .gitignore.
The file can be a Key-Value text file or a JSON file.

Eclipse immediately undeletes deleted file

When attempting to delete log4j.properties Eclipse undeletes in the very next moment. The file is not used at the moment, no build process is running, the project containing the file is not being deployed. Yet the file is being restored immediately. Even when the IDE and all shell (ie. Git bash) sessions are closed and the file is not open anywhere, it can be successfully deleted using Windows Explorer or Total Commander, but the moment the IDE is started the file is there again.
The intention was to replace the old properties structure with an xml, but I couldn't even overwrite it as upon saving the original content got restored. Any advice on this?

Restore a deleted file in the Visual Studio Code Recycle Bin

Using Visual Studio Code Version 1.8.1 how do I restore a deleted file in the recycle bin?
It uses the normal trash bin of your system. So you can grab it our of there.
In Windows you find it in the explorer, in Linux it is as well in Konquerer / Nemo / ...
First go to Recycle Bin of your local machine.
Your VS code deleted files is there in Recycle Bin.
So, Right click on deleted files and select-> Restore option then your deleted files
will be automatically restored in your VS code.
If you just deleted the file, know that VSCode 1.52 (Dec. 2020) will support:
Undo file operations in Explorer
Explorer now supports Undo and Redo for all file operations: delete, rename, copy, move, new file and new folder.
Make sure the focus is in the Explorer and trigger the Undo or Redo commands and your last file operation will be undone or redone respectively.
Keep in mind that we have separate undo stacks for the editor and the explorer and we choose which one to undo based on focus.
Running on Ubuntu 18.04, with VS code 1.51.0
My deleted files from VS Code are located at:
~/.local/share/Trash/files
Every deleted file have a corresponding .trashinfo file which contains details about where the file is deleted from and deletion date and these are located at:
~/.local/share/Trash/info
More info here.
To search for your deleted files:
find ~/.local/share/Trash/files -name your_file_name
In case you deleted files form a mounted ntfs filesystem, they will be located at:
/path_to_mounted_fs/.Trash-$UID
You can get $UID by doing echo $UID in your terminal.
Hope my case helped!
Click in empty space of VS Code's explorer (it's where you see files listed vertically) and press undo Ctrl + z
It'll recover your permanently deleted files too.
VS Code is a lifesaver. ✌
I know the OP says Recycle Bin. What I do though is recreate the file, especially if it's a single file. And when in the file, I just press CMD+Z (I'm on a Mac) and I get my file back.
Recreate the file in the same directory from where it was
deleted.
CMD+Z inside of the newly created file.
I accidentally discarded changes in the Source Control in VS Code, I just needed to reopen this file and press Ctrl-Z few times, glad that VS Code saves your changes like that.
If you can't find your files in the Windows Recycle Bin as it happended to me
(debugger went rogue and deleted the project folder)
look in the %APPDATA%\Code\User\History\ subfolders sorted by date modified.
There I could retrieve my seemingly lost files.
who still facing the problem on linux
and didnt find it on trash
try this solution
https://github.com/Microsoft/vscode/issues/32078#issuecomment-434393058
find / -name "delete_file_name"
If you have permanently deleted files, on macOS, you can see the history (the last month I guess) in $HOME/Library/Application Support/Code/User/History/. You will have to find your file(s) by looking at each entries.json file in every subfolder and rename the last version of your file.
There is probably a similar way on windows and linux but I don't know the precise paths.
I tried most of the options above but none worked.
What worked for me was clicking and highlighting the folder where the file was deleted from in vscode. Then while it is selected, hit CTRL + Z.
This works on windows.
Hitting CTRL+Z without highlighting that folder didn't work.
Just look up the files you deleted, inside Recycle Bin. Right click on it and do restore as you do normally with other deleted files. It is similar as you do normally because VS code also uses normal trash of your system.
While pushing a repository to Github through Vs Studio code I deleted whole folder and they were not available in Recycle bin also. Here is how I recovered those files.
For Windows.
The method is to restore the previous version of the Drive in which the deleted file existed
I had deleted files from G: drive, the below images are self explanatory
Open properties menu of the drive
In properties go to previous versions tab,
where you can find the previously stored versions of that drive along with date at time of backup
use open or click on restore to get the previous version of that drive.
Note: Manipulations in the drive after restore point won't be available
I am not sure how I deleted a file in VS Code, and couldn't find it in recycle bin. Found the file using the History feature of File Explorer.
A month recovery can be done in visual studio code
1 Right click on file and
2 click Open Timeline and
3 select file from timeline
4 the last time file saved by you
5 and your last change of the file is recovered
NOTE : Not only last but all the previously saved check points can be recoverd from vs code
For Mac, try to search some parts of the code in the deleted file in the following path:
~/Library/Application Support/Code
I found a deleted file in this folder
~/Library/Application Support/Code/Backups
Yes, I know this question is about VS Code but I think I can help someone.
I permanently deleted a file, and I tried all the tips wrote here with no success. So I had to recover the file from OS Linux following this
grep -a -C 500 -F 'Unique string in text file' /dev/sda
It was asked above if there is a way to disable the ability to delete a file you created with an undo (#rochasdv).
There is a new setting to disable undo for file operations:
Explorer: Enable Undo default is warn, confirmation dialog
You can also set it to disable so that your files/folders will not participate in undo operations.
You can alo set it to allow - the pre-new setting situation.
Currently, this new setting is in the Insiders Build v1.64 so it may be in Stable early February, 2022.
I am working on Windows with a Ubuntu WSL. I permanently deleted a file by mistake and was not able to restore it from the recycle bin nor by doing anything else.
I however, was able to get my files content by going to "Timeline" and see all my previous modification (it will open a comparison window).
Hope it will help somebody.
I had the case that I, accidentally, deleted a committed file (git) with a ton of additional uncommitted changes, and I could not get it back. (two days of work! yeah, I know, commit early commit often, I know ...)
I had no linux trash can setup on my docker instance and was developing via remote ssh.
I tried to recreate the file and then do a ctrl+Z to recapture the changes as some suggested here. This did not work for me.
So after a struggle over an hour I finally gave up and thought the changes to the file were lost.
However,
I discarded the changes in git, that the file was deleted.
And THEN I retried ctrl+Z and boom all the changes previously came back
magically!
I was a happy camper!
If your local directory has git initialized and you have not committed the changes that include the delete, you can use git checkout -f to throw away local changes.
If you completely delete any of the components in angular using visual code, you can restore it
Go to Recycle Bin and restore the deleted component that will be restored in the project.

cp: copyFileSync: could not write to dest file (code=EBUSY)

I have an issue using the copy task in https://www.visualstudio.com/docs/build/steps/utility/copy-files
My task failed with an error cp: copyFileSync: could not write to dest file (code=EBUSY): ...
Looking up, I found out that somehow the file couldn't be overridden. When I delete that file and queue the build again, it succeeded.
Is there any permanent solution for this issue? I don't want to use the option "Clean target folder" in the copy task because in that folder there will be additional files that are not copied by the build task.
According to the error message, the file is being used when the copy files task is running. You need to check which application is using it and make sure the application is closed when the task running. If the file is locked by any application, you may get "rm: could not remove the file (code EBUSY):..." error message even if you use the "Clean target folder" option.
You run a web server reset command as workaround to pass through this problem if your application is running on web server for the open files to be released.
