Not possible to save huge file ("Invalid string length")

[mehrdd]

Hello,

I have a mysqldump file which is 620mb.
it opens fine and it's way faster than sublime text (except highlighting SQL which is not important for such a big file)

but when i try to save the file it says : "Invalid string length"

VSCode : Version 1.15.0 (1.15.0)

This is an out of memory exception. Here is the stack trace:

Invalid string length: RangeError: Invalid string length
    at Array.join (native)
    at Model.TextModel.getValueInRange (file:///Users/bpasero/Development/Microsoft/monaco/out/vs/editor/common/model/textModel.js:325:32)
    at Model.TextModel.getValue (file:///Users/bpasero/Development/Microsoft/monaco/out/vs/editor/common/model/textModel.js:293:39)
    at TextFileEditorModel.BaseTextEditorModel.getValue (file:///Users/bpasero/Development/Microsoft/monaco/out/vs/workbench/common/editor/textEditorModel.js:135:30)

Looks like we should change our IFileService.updateContent method to work with a stream instead of requiring the entire value to be there upfront. We call this method 2 times, once for creating a backup of the file and once for saving the contents back.

I have a similar issue - but mine is for reading a file.

The file is a 13.12GB JSON Firebase backup file. I may be pushing the limit on VSCode's new "large file support", but figured I'd try :). The Macbook Pro I am using has 16GB RAM.

It looks like V8 62 lifts the max string length to 2^30 (via https://v8project.blogspot.ch/2017/09/v8-release-62.html):

The maximum string length on 64-bit platforms increased from 2**28 - 16 to 2**30 - 25 characters.

(from 256 MB => 1 GB)

Same problem on saving huge files.
Any updates to this issue?

I have the same problem, when I'm trying to save huge file. And when I click on Close button after this error I get another:
Cannot read property 'message' of undefined
