Re: git rm / format-patch / am fails on my file: patch does not apply
Hi Philip. I don't have any setting like that in either my ~/.gitconfig, or in the .git/config files. I really haven't tweaked my git config at all. This is a typical .git/config file: [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true [remote origin] url = ssh://ktan...@git.code.sf.net/p/agency/code fetch = +refs/heads/*:refs/remotes/origin/* [branch master] remote = origin merge = refs/heads/master My ~/.gitconfig just has name and email settings in it.

I am not very much surprised if such a file misbehaves, because the format-patch | am pipeline is designed to be used on patches that can be transferred in plain-text e-mail safely. Long lines should probably be OK, but mixed CRLF, CR and LF may be problematic. I'm not sure I understand this comment. format-patch seems to work fine on binary files. So if it can handle any random collection of bytes, why not text files with (admittedly funky) CRs and LFs?

Not having read the man page, but copied this global config from some '1000 git tips in 5 minutes' years ago, I do expect a setting set to warn to actually not change the program flow except some inserted prints with warnings.

The formatted patch does have the same file endings on the respective line of that file here. I was trying to change just one line ending to 2 lines (LF CR - LF LF) with a hex editor, so there it becomes a smaller (and more debugable ) patch.

This file seems to be a special nasty kind, as the number of LFs is equal to the number of CRs in the file (373 of 0x0a and 0x0d each), but only 343 occurences of LF strictly following a CR, so there are 30 CRs and 30 LFs. This shouldn't be as problematic as my first thought was, there is never a direct comparison of stats.cr to stats.lf in convert.c. The CR and LF count are only compared to either the crlf count or 0.

git rm / format-patch / am fails on my file: patch does not apply
I originally posted about this to the git-users list (https://groups.google.com/forum/#!topic/git-users/G5D0bldEbTo). If this would normally be expected to work: git add file git commit git rm file git commit git format-patch HEAD~1 git reset --hard HEAD~1 git am 0001*patch then I'm having a problem with at least one (maybe more) file I have in a repository that seems like a bug. Even if I copy it to a new repository, it will still fail, so it seems something about how git handles the file, which file reports as: ASCII text, with very long lines, with CRLF, CR, LF line terminators I've confirmed with the following test case on three machines, so it seems reproducible: mkdir temp_test_case cd temp_test_case git init # my file.
