Re-use the existing crlf data generation script for creating the to-odb dataset. Also, store the actual file contents instead of the ID so that we can identify differences instead of detecting that differences exist.

# This script will generate the test corpus for CR/LF data using git;
|
|
# we create files with all possible line ending varieties (all LF, all
|
|
# CRLF, mixed, etc) on all the possible line ending configurations
|
|
# (`core.autocrlf=true`, `text=auto` in gitattributes, etc). This
|
|
# allows us to validate that our configuration will match byte-for-byte
|
|
# the configuration that git produces.
|
|
#
|
|
# To update the test resource data, from the test resource directory:
|
|
# git rm -r ./crlf_data/{posix,windows}
|
|
# sh ./generate_crlf.sh ./crlf ./crlf_data /tmp/crlf_gitdirs
|
|
# git add ./crlf_data/{posix,windows}
