Another way to examine your changes is with the svn diff command.
For example, if you asked svn diff to compare revisions 99 and 102 of foo.
In fact, it turns out that there are three distinct uses of svn diff.
Run svn diff to see unified diff output of your changes.
Add the--ignore-ancestry option to your merge command,and it will behave just like svn diff.
You can still use svn diff and redirect its output to create a usable patch file.
(And conversely, the--notice-ancestry option will cause svn diff to behave like the merge command.).
We have already seen svn diff before- it displays file differences in unified diff format;
The reason for bringing this up is to point out an important difference between svn diff and svn merge.
For example, you can ask svn diff to show you the exact change made by Sally in revision 344.
If Sally's change had, say, added a new directory,the output of svn diff wouldn't have mentioned it at all.
Svn diff only outputs the limited patch-format, so there are some ideas it simply can't express.
(And conversely, the--notice-ancestry option will cause svn diff to behave like the merge command.) Common Use-Cases.
The svn diff command produces this output by comparing your working files against its pristine text-base.
You can see exactly what changes you have made by using svn status, svn diff, and svn revert.
A word of warning: while svn diff and svn merge are very similar in concept, they do have different syntax in many cases.
C in context output format while ignoring whitespace changes,you might run svn diff--diff-cmd /usr/bin/diff--extensions'-bc' foo.c.
The svn diff command produces this output by comparing your working files against the cached“pristine” copies within the. svn area.
This does, unfortunately, mean that to fully apply a patch generated by svn diff, any property modifications will need to be applied by hand.
As we have seen, invoking svn diff with no switches will compare your working files to the cached“pristine” copies in the. svn area.
It's useful for getting a“high level” preview of the potential merge, for those times when running svn diff gives too much detail.
You can use the commands svn status, svn diff, and svn revert without any network access even if your repository is across the network.
Also, you can receive interesting information about the state of your file anddirectory properties by using the svn status and svn diff commands.
You can find out exactly how you have modified things by running svn diff with no arguments, which prints out file changes in unified diff format:[4].
Svn diff also prints filename and offset information useful to the patch program, so you can generate“patches” by redirecting the diff output to a file:$ svn diff> patchfile.
Keep in mind that rolling back a change like this is just like any other svn merge operation,so you should use svn status and svn diff to confirm that your work is in the state you want it to be in, and then use svn commit to send the final version to the repository.
Not only can you use svn diff to compare files in your working copy to the repository, but if you supply a URL argument, you can examine the differences between items in the repository without even having a working copy.
Since svn merge operates like svn diff, comparing the latest trunk and branch trees will not merely describe the set of changes you made to your branch.
Instead of running svn diff and sending a patch file(which won't capture tree changes, symlink changes or changes in properties), you can instead use svn copy to“upload” your working copy to a private area of the repository.
One simple way to do that is to run svn diff with the same arguments you plan to pass to svn merge, as we already showed in our first example of merging.
