Hi folks, *Short Version:* * * I may have a fix for Jenkins-14551 ( https://issues.jenkins-ci.org/browse/JENKINS-14551). I've submitted this potential resolution to SVNKit as well as their 1.7.6 SVN branch has the same issue (http://issues.tmatesoft.com/issue/SVNKIT-368). I've compiled the change into the subversion-plugin on my test server, and the fix appears to work.
Can a contributor peer review this change? How do I go about submitting this fix to the Jenkins SVNKit repo? Do I need a unit test before I can do a pull request? The bug is obvious when you look at the code, and the unit test setup and execution seems like it would be complicated. I've forked the Jenkins SVNKit repo and committed the modification here: https://github.com/theotherwhitemeat/svnkit-1/commit/27decb28216ee4fd15b8fcbdb769bf41d81978eb *Longer Version:* * * In org.tmatesoft.svn.core.internal.wc.SVNUpdateEditor15.java, in function addFileWithHistory (line 867), there's a code block that calls myFileFetcher.fetchFile() twice. Each time this is called, baseTextOS is written to. Upon the second write, the file contents are duplicated. Here's the code: baseTextOS = SVNFileUtil.openFileForWriting(info.copiedBaseText); myFileFetcher.fetchFile(copyFromPath, copyFromRevision, baseTextOS, baseProperties); SVNChecksumOutputStream checksumBaseTextOS = new SVNChecksumOutputStream(baseTextOS, SVNChecksumOutputStream.MD5_ALGORITHM, true); baseTextOS = checksumBaseTextOS; myFileFetcher.fetchFile(copyFromPath, copyFromRevision, baseTextOS, baseProperties); info.copiedBaseChecksum = checksumBaseTextOS.getDigest(); I was able to find this by stepping through the code using NetBeans IDE 7.3 attached to a remote debugging session on Jenkins. I've compiled and tested this change inside the context of the subversion-plugin and the file contents are no longer duplicated. I've forked the svnkit repo used in Jenkins here, and committed this change if anyone would like to download the fix and do some testing: https://github.com/theotherwhitemeat/svnkit-1/commit/27decb28216ee4fd15b8fcbdb769bf41d81978eb Here's my patch: Index: SVNUpdateEditor15.java =================================================================== --- SVNUpdateEditor15.java (revision 9722) +++ SVNUpdateEditor15.java (working copy) @@ -864,7 +864,6 @@ OutputStream baseTextOS = null; try { baseTextOS = SVNFileUtil.openFileForWriting(info.copiedBaseText); - myFileFetcher.fetchFile(copyFromPath, copyFromRevision, baseTextOS, baseProperties); SVNChecksumOutputStream checksumBaseTextOS = new SVNChecksumOutputStream(baseTextOS, SVNChecksumOutputStream.MD5_ALGORITHM, true); baseTextOS = checksumBaseTextOS; Thank you, Kenny Ayers -- You received this message because you are subscribed to the Google Groups "Jenkins Developers" group.
