I am rather new to SVN, and actually use it mostly via GIT, i.e. `git svn

What is the best way to backport specific patches from trunk to 8.5, 7.0,
etc.? Patch utility? SVN Merge? GIT cherry-pick (though the git
mirrors
have a separate repos which adds some complexity I think)
I'd appreciate any tips that will point me in the right direction, or if
anyone can share their workflow.
I use svn for backports. I use the following scripts. The first to merge
from trunk to 8.5.x, the second to merge from 8.5.x to 7.0.x. I `cd`
into the root of the repo for the version I want to merge to and then
call the script with the revision of the commit I want to back-port.
HTH,

mark@study04:~/bin$ cat tc-merge.sh
#!/bin/sh
svn up
svn merge -c $1 https://svn.apache.org/repos/asf/tomcat/trunk
mark@study04:~/bin$ cat tc85-merge.sh
#!/bin/sh
svn up
svn merge -c $1 https://svn.apache.org/repos/asf/tomcat/tc8.5.x/trunk
It helps, thanks, but I don't know if the target file has been changed or
if I did something wrong, I'm getting a conflict (in git I can see the
differences and choose resolution, but here I don't know which one to
pick). Or is it because I waited too long and didn't do this immediately
after committing the original patch to trunk?
Here's the output from the script:
tc8.5.x]$ ~/bin/svn-merge-tc-trunk-to-85.sh 1842849

Subversion is not smart enough to resolve this tree conflict automatically!
Apparently neither am I :s
Not sure, but from the prompt it looks like your shell working directory
is a 8.5 checkout and your are using the script that contains the
command to merge from 8.5 to some older branch.
When standiung in 8.5 you want to merge from trunk (9.0) into 8.5. That
would be done by the tc-merge.sh script. You might now need to first
reset your checkout using something like "svn -R revert ." before try
running that script.
