The easiest way to revert the changes from a single revision,
or from a range of revisions,
is to use the revision log dialog.
This is also the method to use of you want to discard recent
changes and make an earlier revision the new HEAD.
Select the file or folder in which you need to revert
the changes. If you want to revert all changes, this
should be the top level folder.
Select
TortoiseSVN → Show Log
to display a list of revisions. You may need to use
Show All or
Next 100
to show the revision(s) you are interested in.
Select the revision you wish to revert. If you want
to undo a range of revisions, select the first one
and hold the Shift key while selecting the last one.
Note that for multiple revisions, the range must be
unbroken with no gaps.
Right click on the selected revision(s),
then select
Context Menu → Revert changes from this revision.
Or if you want to make an earlier revision the new HEAD revision,
right click on the selected revision,
then select
Context Menu → Revert to this revision.
This will discard all changes after
the selected revision.
You have reverted the changes within your working copy.
Check the results, then commit the changes.
B.4.2. Use the merge dialog
To undo a larger range of revisions, you can use the Merge dialog.
The previous method uses merging behind the scenes; this method
uses it explicitly.
In your working copy select
TortoiseSVN → Merge.
In the From: field enter the full
folder URL of the branch or tag containing the changes
you want to revert in your working copy. This should come
up as the default URL.
In the From Revision field enter the
revision number that you are currently at. If you are
sure there is no-one else making changes, you can use the
HEAD revision.
make sure the Use "From:" URL
checkbox is checked.
In the To Revision field enter the
revision number that you want to revert to, namely the one
before the first revision to be reverted.
Click OK to complete the merge.
You have reverted the changes within your working copy.
Check the results, then commit the changes.
B.4.3. Use svndumpfilter
Since TortoiseSVN never loses data, your “rolled back”
revisions still exist as intermediate revisions in the repository. Only
the HEAD revision was changed to a previous state.
If you want to make revisions disappear completely from your
repository, erasing all trace that they ever existed, you have
to use more extreme measures. Unless there is a really good reason
to do this, it is not recommended. One
possible reason would be that someone committed a confidential
document to a public repository.
The only way to remove data from the repository is to use the
Subversion command line tool svnadmin.
You can find a description of how this works in the
Repository Maintenance.
