accidently press of ctrl+C or Option+C clears clipboard. even nothing is selected

Brackets version
I found following bug in Brackets Release 0.42 and 0.43. I don't know if it has in previous versions.

OS version
Mavericks 10.9.4

steps to trigger the problem
By following this scenario you can notice the bug...

.. type something in Brackets
.. select some text
.. copy that by pressing "Ctrl+C" or "Options+C" or "Edit -> Copy"
.. In the new lines press "Ctrl+V" or "Options+V" etc.. that copied text is pasted..
.. now Don't select anything. and just press "Ctrl/Option+C" on some empty line.
.. try to paste the previously copied text By pressing Ctrl/Option+V... you wouldn't get anything. our pasted text is empty.

what you expected to happen
. while untill we don't select anything, our previously copied text should remain on the clipboard...

What happened
I'm working on a one page application using HTML+JS on one page and CSS on another.. it's 3000 lines of code almost .. It might get longer in next few days..
If i find something within my codes and copy them to paste on other lines.. one accidental press of Option+C or Ctrl+C on next blank lines empties my clipboard

Please notice this as bug and remove this. I have used Adobe Code CC .. This kind of issue doesn't exists in Adobe Code CC.

Summary: Ctrl+C copies entire line when cursor is at beginning or end of line (but not when in middle). This should be prevented when line is empty.

@redmunds I think not in my case. It copies in either cases... either on the beginning or at the end..or even in middle .. it should be prevented until nothing is selected.. not only empty line.. while duplicate works good even if nothing is selected.

This bug is definitely valid. I downloaded Edge Code CC and used the steps @mfarooqi gave, and indeed in Brackets (running at 24b58df on master) copying a blank line actually copies a blank line, while in Edge Code CC (which is based on Brackets 0.38), copying a blank line does nothing. I almost want to call this a CodeMirror bug.

As I thought, it is a CodeMirror bug. I've traced it to codemirror/codemirror5@f4ae5b4, specifically the d.input.value = lastCopied.join("\n"); and d.input.value = text.join("\n"); lines (this also remedies most of my issues in #9130).

I'll file this bug in CodeMirror.

EDIT: Filed as codemirror/codemirror5#2824.

@le717 Nice detective work!

[mfarooqi]

@le717 Thanks for proceeding the further

@redmunds @mfarooqi No prob, I had a few minutes of free time, so I figured I'd track it down. :)

This is currently the intended behavior. Adding 'needs review' and PM tags so we can sort this out. We could consider adding a preference for this...
