Source reading all lines on each change

[hariso]

Bug description

The source connector is reading all lines on each change.

Steps to reproduce

1. Run a pipeline with the following config:

---
version: 1.0
pipelines:
  pipeline1:
    status: running
    name: pipeline1
    description: 'file source, file destination'
    connectors:
      file-source:
        type: source
        plugin: "builtin:file"
        name: file-source
        settings:
          path: /home/haris/projects/other/conduit-utils/file-source.txt
      file-destination:
        type: destination
        plugin: "builtin:file"
        name: file-destination
        settings:
          path: /home/haris/projects/other/conduit-utils/file-destination.txt

2. Write a new line to the source file.
3. Check the destination file

Expected behavior: Only the new line appears in the destination file.

Actual behavior: All the lines in the source file are added to the destination file.

I was using the Sublime text editor to edit the source file. When using echo, this issue is not reproduced. It looks like Sublime is always overwriting a file when saving it.
