From: Christian Halstrick <christian.halstrick@xxxxxxx> Honor the configuration parameter core.logAllRefUpdates when writing reflogs. Instead of writing reflog entries always only write reflogs if this parameter is set to true or if the corresponding file in the <git-dir>/logs directory already exists. In other words: if you are updating a ref and this parameter is set to false and there is no file corresponding to your ref in the <git-dir>/logs folder then no reflog will be written. This is a fix for the issue http://code.google.com/p/egit/issues/detail?id=4 Signed-off-by: Matthias Sohn <matthias.sohn@xxxxxxx> Signed-off-by: Christian Halstrick <christian.halstrick@xxxxxxx> --- .../tst/org/spearce/jgit/lib/ReflogConfigTest.java | 116 ++++++++++++++++++++ .../src/org/spearce/jgit/lib/CoreConfig.java | 10 ++ .../src/org/spearce/jgit/lib/RefLogWriter.java | 18 ++-- .../src/org/spearce/jgit/lib/Repository.java | 1 + 4 files changed, 137 insertions(+), 8 deletions(-) create mode 100644 org.spearce.jgit.test/tst/org/spearce/jgit/lib/ReflogConfigTest.java diff --git a/org.spearce.jgit.test/tst/org/spearce/jgit/lib/ReflogConfigTest.java b/org.spearce.jgit.test/tst/org/spearce/jgit/lib/ReflogConfigTest.java new file mode 100644 index 0000000..7f067c0 --- /dev/null +++ b/org.spearce.jgit.test/tst/org/spearce/jgit/lib/ReflogConfigTest.java @@ -0,0 +1,116 @@ +/* + * Copyright (C) 2009, Christian Halstrick, Matthias Sohn, SAP AG + * + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or + * without modification, are permitted provided that the following + * conditions are met: + * + * - Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * + * - Redistributions in binary form must reproduce the above + * copyright notice, this list of conditions and the following + * disclaimer in the documentation and/or other materials provided + * with the distribution. + * + * - Neither the name of the Git Development Community nor the + * names of its contributors may be used to endorse or promote + * products derived from this software without specific prior + * written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND + * CONTRIBUTORS "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, + * INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES + * OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE + * ARE DISCLAIMED.
