Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.
What did you do before the bug happened? (Steps to reproduce your issue)
create a file containing multiline trailer:
$ echo "Test" > test.txt
$ git interpret-trailers --where end --if-exists addIfDifferent
--trailer "SingleLineTrailer: This is a single line trailer"
--in-place test.txt
$ git interpret-trailers --where end --if-exists addIfDifferent
--trailer "MultiLineTrailer: This is"$'\n a folded multi-line\n
trailer' --in-place test.txt
parse trailers:
$ git interpret-trailers --parse test.txt
SingleLineTrailer: This is a single line trailer
MultiLineTrailer: This is a folded multi-line trailer
(so far, all is as expected)
now, adding multiline trailer containing empty line:
$ git interpret-trailers --where end --if-exists addIfDifferent
--trailer "MultiLineTrailer: This is"$'\n a folded multi-line\n
trailer which\n \n contains an\n empty line' --in-place test.txt
parse trailers again:
$ git interpret-trailers --parse test.txt
What did you expect to happen? (Expected behavior)
I would expect the following output:
$ git interpret-trailers --parse test.txt
SingleLineTrailer: This is a single line trailer
MultiLineTrailer: This is a folded multi-line trailer
MultiLineTrailer: This is a folded multi-line trailer which
contains an empty line
What happened instead? (Actual behavior)
no output is generated, but exit code is nevertheless 0:
$ git interpret-trailers --parse test.txt
$ echo $?
0
What's different between what you expected and what actually happened?
I would expect either to get an output or the call to exit non-zero
Anything else you want to add:
According to my interpretation of the documentation of git
intepret-trailers, empty lines should be supported if properly folded,
in the same way as for example the PGP signature added to the commit
header contains a (properly folded) empty line
Please review the rest of the bug report below.
You can delete any lines you don't wish to share.
