+Subject: [PATCH] t/lib-httpd: try harder to find a port for apache
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When running multiple builds concurrently, tests which run daemons, like
+apache httpd, sometimes conflict with each other, leading to spurious
+failures:
+
+    ++ /usr/sbin/httpd -d '/tmp/git-t.ck9I/trash directory.t9118-git-svn-funky-branch-names/httpd' \
+       -f /builddir/build/BUILD/git-2.37.2/t/lib-httpd/apache.conf -DDAV -DSVN -c 'Listen 127.0.0.1:9118' \
+       -k start
+    (98)Address already in use: AH00072: make_sock: could not bind to address 127.0.0.1:9118
+    no listening sockets available, shutting down
+    AH00015: Unable to open logs
+    ++ test 1 -ne 0
+
+Try a bit harder to find an open port to use to avoid these intermittent
+failures.  If we fail to start httpd, increment the port number and try
+again.  By default, we make 3 attempts.  This may be overridden by
+setting GIT_TEST_START_HTTPD_TRIES to a different value.

+Run svnserve in daemon mode and use 'test_atexit' to stop it.  This is
+cleaner than running in the foreground with --listen-once and having to
+manage the PID ourselves.
