RE: Redirection "svn info -r HEAD"

The TortoiseSVN build of the commandline binaries in 1.9.0 and 1.9.1 have known issues. Please retry with another release (following the CRT linkage rules), or use a newer 1.9.x daily build of TortoiseSVN where the linkage problem is fixed.

I’m not sure if this fixes your specific problem, but I don’t have this known broken set of commandline binaries installed on my system. (I had to track a few similar cases earlier this week, all caused by this CRT linkage problem)

Subject: Redirection "svn info -r HEAD"

TL;DR: "svn info -r HEAD > testfile" produces and empty file with svn 1.9.1 on Windows. But svn 1.8.13 produces expected output in the file. Does this only happen for me?

When I updated to TortoiseSVN 1.9.1 (from 1.8.11), which uses svn 1.9.1 it seems redirection of "svn info -r HEAD" (or any other revision specification) no longer works for me in MS Windows. So I wonder if anyone else has experienced this too with subversion 1.9.1?

Some steps to reproduce the issue.
1. Install TortosieSVN 1.9.1
2. In a cmd.exe prompt with cwd being a svn working copy, type:
 svn info
(expected output)
 svn info > testfile
 type testfile
(output that matches running without redirection)
3. Then try with the revisionargument (using -r or --revision):
 svn info -r HEAD
(expected output)
 svn info -r HEAD > testfile
 type testfile
(nothing, i.e .file is empty; cf. running without the redirect)

And just for the sake of testing adding "--xml" makes svn info produce the expected output to the redirected file (that is "svn info -r HEAD --xml > testfile" works). So it seems only "plain"/"old" output is broken.

Downgrading to TortoiseSVN 1.8.11 which uses svn 1.8.13 makes "svn info -r HEAD > testfile" produce the expected file contents in the test file again.

For good measure, I've also tested building on a Linux machine, using subversion 1.9.1 (build from the svn tag/1.9.1). Redirection of "svn info -r ..." works as expected with that build. (My distro uses 1.8.13 currently so that's why I build from vanilla sources to test that). So this seems to only affect Windows.

Some additional info:
OS version: Windows 7 Professional (x64)

I couldn't find any bug report for this, but maybe I just didn't ask the database the right question. I haven't had time to try to build trunk or 1.9.1 vanilla on Windows, and I don't know if TortoiseSVN applies any patches on top of the svn it includes (I'd guess they do not apply any though).

Passing a path to a repo does not affect the behavior. Passing an invalid revision (e.g. "-r FOOBAR") produces an error message (as expected).

Cheers
