Hi, I've found the following issue. When I pipe the output of "svn diff --diff-cmd diff" and a broken pipe occurs on the diff command, I get a "Broken pipe" error:
diff: standard output: Broken pipe svn: E200012: 'diff' returned 2 Tested with svn, version 1.14.1 (r1886195) under Debian 11 (bullseye). The cause is that svn runs the diff command with SIGPIPE ignored, so that diff gets an EPIPE write error instead of being killed by the signal. I think that a fix should be to reset SIGPIPE to the default action just before executing the external diff command. To reproduce the bug: ---------------------------------------- #!/bin/sh set -e export LC_ALL=C mkdir my-test-svn cd my-test-svn svnadmin create svn svn co file://`pwd`/svn wc cd wc seq 10000 > file svn add file svn diff | head svn diff --diff-cmd diff | head cd ../.. rm -rf my-test-svn ---------------------------------------- This gives: Checked out revision 0.
