Stefan Hett created SVN-4660:
--------------------------------
Summary: svn info --show-item=revision produces trailing whitespace
Key: SVN-4660
URL: https://issues.apache.org/jira/browse/SVN-4660
Project: Subversion
Issue Type: Bug
Components: cmdline client
Affects Versions: 1.9.4
Reporter: Stefan Hett
Steps to reproduce:
1. Run svn info --show-item=revision >out.txt
Expected result:
The file out.txt contains just the revision number and a newline.
Actual result:
The file out.txt contains the revision number, followed by some whitespaces and
a newline.
The issue was passed on to the dev list here:
http://mail-archives.apache.org/mod_mbox/subversion-dev/201610.mbox/browser
Rational for this being a bug/unintended behavior:
1. One (if not the) main use-case for the newly introduced --show-item option
is to make it easier to be used in scripts. For revisions, I used that to
generate a revision range as in: -rXXX:YYY. XXX was retrieved using
--show-item=revision. Since that produced unexpected trailing whitespaces the
script command resulted in [...] -rXXX :YYY [...] which obviously caused an
error message which was hard to debug since I didn't immediately get the idea
that the trailing whitespaces might cause the script error I saw.
2. It's not what the documentation in the release notes state:
https://subversion.apache.org/docs/release-notes/1.9.html#svn-info-item
where it's explicitly shown that the reported revision number does not have any
trailing whitespace:
{noformat}
## Display the youngest revision of a repository:
% svn info --show-item=revision

## Find the root directory of a working copy:
% svn info --show-item=wc-root
/home/jrandom/src/svn/trunk
