newlines about bfg-repo-cleaner HOT 3 CLOSED

Please make it preserve cr/lf at least on unaffected files. After running bgf repo cleaner all files where converted from lf to crlf.

This is definitely not how the BFG is supposed to behave, and I suspect that the BFG wasn't responsible for these changes.

If a file isn't specified for a change, the BFG will leave it exactly how it is, verifiable to the fidelity of a SHA-1 hash. If a file is specified for a change, the BFG will use this specific library for processing the text, which specifically preserves line-breaks:

It's possible there is a bug somewhere, but it's a bit unlikely. If you could provide a small sample repo containing 'LF' line endings, along with a BFG command that exhibits the behaviour you specify when run against the repo, I can take a further look?

Sorry, I can't provide a sample. Command was bfg --replace-text passwords.txt .git in the root directory where .git was.

I've added a couple of specific tests for newline-preservation with #486, but they pass successfully and I haven't been able to reproduce the issue you saw. I think it's quite likely that the newline changes you saw were produced by some other effect than the action of the BFG. If you'd like to produce a small sample repo and a mock passwords.txt that reproduces the issue, I could take another look, but otherwise I'll be closing this issue for now.
