# CRLF Handling
# -------------
# The ideal situation would be to do no EOL normalization. Each file
# would have a default EOL, and tools on Windows and Linux would handle
# both EOL formats.
# We're not in the ideal world. A popular editor on Windows (possibly
# Visual Studio) silently introduces EOL corruption -- it displays an
# LF-file normally, but any newly added lines have CRLF. On Linux,
# Emacs and versions of VI handle LF-files and CRLF-files properly.
# However, emacs doesn't like files with both LF and CRLF EOLs. Editing
# the file without additional action will increase the EOL corruption
# in the file.
# Another vector for mixed EOLs is scripts. We mostly don't have scripts
# that add new lines -- so we rarely see this. However, one major event
# in the tree was the addition of copyright headers using a script. That
# script introduced EOL corruption.
# Any automated EOL normalization of files already in the repository will
# cause difficulties in traversing histories, assigning blame, etc. So, we
# don't want to change what's in the repository significantly, even if it
# causes trouble.
# What we do now:
# a) we ensure that there's no further corruption of LF-files. So, we use
# git's 'crlf' attribute on those files to ensure that things are fine
# when we work on Windows. We could use 'crlf=input', but it doesn't buy
# us much -- we might as well be working with consistent EOLs for files in
# working directories as well as in the repository
# b) if the file already of CRLFs, we don't do any normalization. We use '-crlf'
# so that git doesn't do any EOL-conversion of the file. As I said, this
# is mostly harmless on Linux. We can't mark these files as 'crlf' or use
# the new (git 1.7.2) 'eol=crlf' attribute, since it changes the contents
# _inside_ the repository [1], and hence makes history traversal annoying.
# So, we live with occasional EOL corruption.
# c) We can handle mixed-EOL files on a case-by-case basis, converting them to
# LF- or CRLF-files based on which causes fewer lines to change
# d) We try to ensure no further headaches, by declaring EOL normalization on
# code files, and Unix-flavoured files, like shell-scripts, makefiles, etc.
# [1] GIT use LFs as the normalized internal representation.
