Where to get svn

When you commit your change to button. To bring her project up to date, Sally can ask Subversion to update her working copy, by using the svn update command. This will incorporate your changes into her working copy, as well as any others that have been committed since she checked it out. The output from the svn update command indicates that Subversion updated the contents of button.

Note that Sally didn't need to specify which files to update; Subversion uses the information in the. As a general principle, Subversion tries to be as flexible as possible. One special kind of flexibility is the ability to have a working copy containing files and directories with a mix of different working revision numbers.

Subversion working copies do not always correspond to any single revision in the repository; they may contain files from several different revisions.

For example, suppose you check out a working copy from a repository whose most recent revision is At the moment, this working directory corresponds exactly to revision 4 in the repository.

However, suppose you make a change to button. Assuming no other commits have taken place, your commit will create revision 5 of the repository, and your working copy will now look like this:. Suppose that, at this point, Sally commits a change to integer.

If you use svn update to bring your working copy up to date, it will look like this:. Sally's change to integer. In this example, the text of Makefile is identical in revisions 4, 5, and 6, but Subversion will mark your working copy of Makefile with revision 6 to indicate that it is still current. So, after you do a clean update at the top of your working copy, it will generally correspond to exactly one revision in the repository. Just because you're ready to submit new changes to the repository doesn't mean you're ready to receive changes from other people.

And if you have new changes still in progress, svn update should gracefully merge repository changes into your own, rather than forcing you to publish them. The main side effect of this rule is that it means a working copy has to do extra bookkeeping to track mixed revisions as well as be tolerant of the mixture.

It's made more complicated by the fact that directories themselves are versioned. For example, suppose you have a working copy entirely at revision You edit the file foo. After the commit succeeds, many new users would expect the working copy to be entirely at revision 15, but that's not the case! Any number of changes might have happened in the repository between revisions 10 and The client knows nothing of those changes in the repository, since you haven't yet run svn update , and svn commit doesn't pull down new changes.

Therefore, the only safe thing the Subversion client can do is mark the one file— foo. The rest of the working copy remains at revision Only by running svn update can the latest changes be downloaded and the whole working copy be marked as revision The fact is, every time you run svn commit your working copy ends up with some mixture of revisions. The things you just committed are marked as having larger working revisions than everything else. After several commits with no updates in between , your working copy will contain a whole mixture of revisions.

Even if you're the only person using the repository, you will still see this phenomenon. Often, new users are completely unaware that their working copy contains mixed revisions.

This can be confusing, because many client commands are sensitive to the working revision of the item they're examining. When the user invokes this command on a working copy object, he expects to see the entire history of the object. But if the object's working revision is quite old often because svn update hasn't been run in a long time , the history of the older version of the object is shown. If your project is sufficiently complex, you'll discover that it's sometimes nice to forcibly backdate or update to a revision older than the one you already have portions of your working copy to an earlier revision; you'll learn how to do that in Chapter 2, Basic Usage.

Perhaps you'd like to test an earlier version of a submodule contained in a subdirectory, or perhaps you'd like to figure out when a bug first came into existence in a specific file. However you make use of mixed revisions in your working copy, there are limitations to this flexibility.

First, you cannot commit the deletion of a file or directory that isn't fully up to date. If a newer version of the item exists in the repository, your attempt to delete will be rejected to prevent you from accidentally destroying changes you've not yet seen. Second, you cannot commit a metadata change to a directory unless it's fully up to date. A directory's working revision defines a specific set of entries and properties, and thus committing a property change to an out-of-date directory may destroy properties you've not yet seen.

Finally, beginning in Subversion 1. This new requirement was introduced to prevent common problems which stem from doing so. You are reading Version Control with Subversion for Subversion 1. Active 1 year, 7 months ago. Viewed 19k times.

I'm on a Windows machine. When I type in svn --version , I get this: 'svn' is not recognized as an internal or external command, operable program or batch file. I'm using TortoiseSVN. Is there some way to view the version through it? Improve this question. Community Bot 1 1 1 silver badge. IIRC Tortoise doesn't come with a command line client, but works with an embedded svn library or something like that.

I don't know of any way to know the server SVN version without accessing the server. KenWhite Where's it? Show 5 more comments. Active Oldest Votes.
