SVN merging is very time consuming (especially on large code bases) and error prone. Eclipse and Netbeans plugins don't serve me very well. At the moment I'm using a combination of manual "svn merge" and the graphical diff Meld. Are there better alternatives (non-win32)?
I figured out how to use SvnMerge, which is a Python script(s), and had quite a lot of success with it. You can google for the instructions I put on my blog, or drop me a line and I'll post the vanity link.
Meld is arguably one of the best and one of the most used tools for non-win32. On Windows or with Wine WinMerge wins hands down. Some alternatives for Linux:
P.S. Actually on Windows the TortoiseSVN merge tool gives great results too :)
Actually there are reports of people using git-svn or hg-svn bridges to download a tree, preform a merge, then upload the merge. Doesn't solve the messiness part but the increased speed of the merge makes it less tedious.
Which platform are you running on? On Windows I use TortoiseSVN to carry out most diffs and merges pretty easily. Only some of the more complicated strands of diffs are performed with UltraCompare.
I really like Sourcegear Diffmerge. http://www.sourcegear.com/diffmerge/
I have recently started using the new Beyond Compare 3 (for Windows and Linux). It seems to consistently make better automated merge decisions then TortoiseSVN or KDiff3. Particularly on whitespace, I believe this is due to BC3s better file type configuration.
I also think its merge interface is cleaner and easier to understand then KDiff.
I've used svnmerge and it helps a lot. It's a command line utility, so it may not be the best tool for everyone, but it's good for me.
