How do I revert an SVN commit?

问题

I have found various examples of how to revert an SVN commit like

svn merge -r [current_version]:[previous_version] [repository_url]

svn merge -c -[R] .

But neither of them seems to work. I tried those commands and checked the files that were changed by hand.

How do I revert a commit with revision number 1944? How do I check that the revert has been done (without looking in the actual file to the changes have been reverted)?

回答1:

Both examples must work, but

svn merge -r UPREV:LOWREV . undo range

svn merge -c -REV . undo single revision

in this syntax - if current dir is WC and (as in must done after every merge) you'll commit results

Do you want to see logs?

回答2:

If you're using the TortoiseSVN client, it's easily done via the Show Log dialog.

回答3:

svn merge -r 1944:1943 . should revert the changes of r1944 in your working copy. You can then review the changes in your working copy (with diff), but you'd need to commit in order to apply the revert into the repository.

回答4:

First, revert the working copy to 1943.

> svn merge -c -1943 .

Second, check what is about to be commited.

> svn status

Third, commit version 1945.

> svn commit -m "Fix bad commit."

Fourth, look at the new log.

> svn log -l 4

------------------------------------------------------------------------
1945 | myname | 2015-04-20 19:20:51 -0700 (Mon, 20 Apr 2015) | 1 line

Fix bad commit.
------------------------------------------------------------------------
1944 | myname | 2015-04-20 19:09:58 -0700 (Mon, 20 Apr 2015) | 1 line

This is the bad commit that I made.
------------------------------------------------------------------------
1943 | myname | 2015-04-20 18:36:45 -0700 (Mon, 20 Apr 2015) | 1 line

This was a good commit.

It is impossible to "uncommit" a revision, but you can revert your working copy to version 1943 and commit that as version 1945. The versions 1943 and 1945 will be identical, effectively reverting the changes.

回答6:

The following will do a dry run, as it says. HEAD being current version, PREV is previous, then the path to your file, or committed item:

svn merge --dry-run -rHEAD:PREV https://example.com/svn/myproject/trunk

If the dry run looks good, run the command without the --dry-run

Verify the change in revision and re-commit. To browse for version numbers try:

svn log

回答7:

F=code.c
REV=123
svn diff -c $REV $F | patch -R -p0 \
    && svn commit -m "undid rev $REV" $F

回答8:

Alex, try this: svn merge [WorkingFolderPath] -r 1944:1943

回答9:

While the suggestions given already may work for some people, it does not work for my case. When performing the merge, users at rev 1443 who update to rev 1445, still sync all files changed in 1444 even though they are equal to 1443 from the merge. I needed end users to not see the update at all.

If you want to completely hide the commit it is possible by creating a new branch at correct revision and then swapping the branches. The only thing is you need to remove and re add all locks.

copy -r 1443 file:///<your_branch> file:///<your_branch_at_correct_rev>
svn move file:///<your_branch> file:///<backup_branch>
svn move file:///<your_branch_at_correct_rev> file:///<your_branch>

This worked for me, perhaps it will be helpful to someone else out there =)

回答10:

svn merge -c -M PATH

This saved my life.

I was having the same issue, after reverting back also I was not seeing old code. After running the above command I got a clean old version code.

回答11:

I tried the above, (svn merge) and you're right, it does jack. However

svn update -r <revision> <target> [-R]

seems to work, but isn't permanent (my svn is simply showing an old revision). So I had to

mv <target> <target backup>
svn update <target>
mv <target backup> <target>
svn commit -m "Reverted commit on <target>" <target>

In my particular case my target is interfaces/AngelInterface.php. I made changes to the file, committed them, updated the build computer ran the phpdoc compiler and found my changes were a waste of time. svn log interfaces/AngelInterface.php shows my change as r22060 and the previous commit on that file was r22059. So I can svn update -r 22059 interfaces/AngelInterface.php and I end up with code as it was in -r22059 again. Then :-

mv interfaces/AngelInterface.php interfaces/AngelInterface.php~
svn update interfaces/AngelInterface.php
mv interfaces/AngelInterface.php~ interfaces/AngelInterface.php
svn commit -m "reverted -r22060" interfaces/AngelInterface.php

Alternatively I could do the same thing on a directory, by specifying . -R in place of interfaces/AngelInterface.php in all the above.

回答12:

If you want to completely remove commits from history, you can also do a dump of the repo at a specific revision, then import that dump. Specifically:

svnrdump dump -r 1:<rev> <url> > filename.dump

The svnrdump command performs the same function as svnadmin dump but works on a remote repo.

Next just import the dump file into your repo of choice. This was tested to worked well on Beanstalk.
