Saving a file should not corrupt existing files when disk is full

[eagles051387]

I save my project files to a Samba file share. Without my awareness of the shared disk being full, I overwrote a previously existing project file in LMMS without any error or warning. LMMS wrote to a file of 0KB in size and the mistake was not made known to me until later when I tried to reload the project again in LMMS.
pgib in irc suggested I write a ticket for this issue, regarding file saving errors, such as the above. I hope pgib won't mind me pasting their words here.
"10:54 <+pgib> That is a defect though: LMMS shouldn't write a 0-sized file without warning. and it definitely shouldn't overwrite an old file until the new one is committed to disk (atomic write)
...
11:48 <+pgib> Something along the lines of: Saving to a file should not corrupt existing files (save to a temporary file, then rename). Additionally, any error to create the new file should result in an error message with the ability to save to a different filesystem."

kriskropd: I made a mistake in the ticket description and I don't know how to edit the original. I mistakenly said that I did not receive an error when overwriting a file in LMMS. I did receive a warning indicating the filename already existed. What I meant was there was no error or warning that the disk was full and that the file would be corrupted.
