setlog - tortoise svn edit commit message
How to edit log message already committed in Subversion? (6)
Is there a way to edit the log message of a certain revision in Subversion? I accidentally wrote the wrong filename in my commit message which could be confusing later.
I've seen How do I edit an incorrect commit message in Git?, but the solution to that question doesn't seem to be similar for Subversion (according to
svn help commit).
Essentially you have to have admin rights (directly or indirectly) to the repository to do this. You can either configure the repository to allow all users to do this, or you can modify the log message directly on the server.
Log messages are kept in the repository as properties attached to each revision. By default, the log message property (svn:log) cannot be edited once it is committed. That is because changes to revision properties (of which svn:log is one) cause the property's previous value to be permanently discarded, and Subversion tries to prevent you from doing this accidentally. However, there are a couple of ways to get Subversion to change a revision property.
The first way is for the repository administrator to enable revision property modifications. This is done by creating a hook called "pre-revprop-change" (see this section in the Subversion book for more details about how to do this). The "pre-revprop-change" hook has access to the old log message before it is changed, so it can preserve it in some way (for example, by sending an email). Once revision property modifications are enabled, you can change a revision's log message by passing the --revprop switch to svn propedit or svn propset, like either one of these:
$svn propedit -r N --revprop svn:log URL $svn propset -r N --revprop svn:log "new log message" URL
where N is the revision number whose log message you wish to change, and URL is the location of the repository. If you run this command from within a working copy, you can leave off the URL.
The second way of changing a log message is to use svnadmin setlog. This must be done by referring to the repository's location on the filesystem. You cannot modify a remote repository using this command.
$ svnadmin setlog REPOS_PATH -r N FILE
where REPOS_PATH is the repository location, N is the revision number whose log message you wish to change, and FILE is a file containing the new log message. If the "pre-revprop-change" hook is not in place (or you want to bypass the hook script for some reason), you can also use the --bypass-hooks option. However, if you decide to use this option, be very careful. You may be bypassing such things as email notifications of the change, or backup systems that keep track of revision properties.
Here's a handy variation that I don't see mentioned in the faq. You can return the current message for editing by specifying a text editor.
svn propedit svn:log --revprop -r N --editor-cmd vim
If you are using an IDE like eclipse, you can use this easy way.
Right click on the project -> Team - Show history
right click on the revision id for your commit and select 'Set commit properties'.
You can modify the message as you want from here.
If your repository enables setting revision properties via the pre-revprop-change hook you can change log messages much easier.
svn propedit --revprop -r 1234 url://to/repository
Or in TortoiseSVN, AnkhSVN and probably many other subversion clients by right clicking on a log entry and then 'change log message'.
The Subversion FAQ covers this, but uses a bunch of confusing undefined terms like
REPOS_PATH without giving any actual examples.
It might take a few tries to get it to work, so save your updated commit message in a file. Unlike with
svn-commit.tmp files, Subversion won’t preserve your typing if there’s a problem.
In your working directory, run
svn propedit -r N --revprop svn:log
to edit the commit message. If that works, great! But it probably won’t, because the
svn:log revision property is unversioned and Subversion by default will stop you from overwriting it, either with the hook script
pre-revprop-change, or an error message that you don’t have such a hook.
To change the hooks, you need access to the filesystem on which the repository is hosted.
svn info will tell you the Repository Root. Suppose it’s
- Is there a
pre-revprop-change.batscript? If so, temporarily comment out the part of it that aborts if you try to change
Otherwise, on Windows, create a blank file called
pre-revprop-change.bat. Here’s one way to do that:
copy con pre-revprop-change.bat ^Z
Otherwise, on Unix, run
echo '#!/bin/sh' > pre-revprop-change chmod +x pre-revprop-change
In the working copy, run
svn propedit -r N --revprop svn:logagain
- Undo your changes to
When you run this command,
svn propedit svn:log --revprop -r NNN
and just in case you see this message:
DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent
Its because Subversion doesn’t allow you to modify log messages because they are unversioned and will be lost permanently.
Go to the hooks directory on your Subversion server (replace ~/svn/reponame with the directory of your repository)
Remove the extension
mv pre-revprop-change.tmpl pre-revprop-change
Make it executable (cannot do chmod +x!)
chmod 755 pre-revprop-change
