Automatic code formatting duplicates lines and blocks of code

[sjuvonen]

There seems to be a bug in automatic code formatting. The bug is triggered by opening the same code file into multiple tabs in separate panes. Having two tabs (of the same file) will cause the bug to occur once, three tabs will cause it to repeat twice, and so on.

I have been using the ide-python package only for a couple days, so I don't know about the specifics. This bug is present in both versions 1.9.4 and 1.9.5 at least. I turned off all checkboxes in the module's settings and restarted Atom, but this bug will still persist. I am using the "format on save" option.

Also, the file status is "modified" again after I save the file and automatic formatting is applied, so the file has to be manually saved twice. I don't think it should be like this.

Example 1

Original code

def foo():
    pass

def bar():
    pass

Result after automating formatting

def foo():
    pass


def bar():
    pass
    pass

Here the keyword pass is duplicated inside function bar.

Example 2

Original code

def foo():
    pass
def bar():
    pass

Result after automating formatting

def foo():
    pass


def bar():
    pass
def bar():
    pass

Here the whole function block for bar is duplicated. Formatting is also messed up.
