The following URL provides URLs about the latest stable releases of Subversion built by third parties for all major operating systems:. On Windows, if you install Subversion through the installer package, then ensure that you choose an installer which includes the server binary files.
Select System , and then Advanced System Settings. Under Advanced , select Environment Variables. This starts the server when you start up your system. You must register svnserve with the service manager. To register svnserve , run the following command:. After Subversion is installed, you must create a repository. The command-line utility called svnadmin is the primary tool for server-side administrative operations. Access to the repository is controlled by file permissions and the user referenced for accessing the repository through the SVN client.
Ensure that user and group permissions for all files in the new repository reflect the type of access control that you want to have over the repository contents. By default, anonymous, read-only access is enabled for a new repository. This means that anyone with SSH access, regardless of repository permissions settings, can check out repository files.
Now that you have created a repository, you can use the Subversion client to perform standard operations against the new repository by using the following base URL:. Refer to the Subversion documentation for information on how to configure other protocols. Although Subversion does not require any particular subdirectory structure within a repository, it is a good idea to follow an established convention, as this book does.
The typical repository layout should resemble the following figure:. Development of the main code line occurs in the trunk directories. When a release is made, the current trunk source is copied into the tags directory, to a tag corresponding to the release. Subversion copy operations are not expensive in terms of storage because the server tracks changes internally.
In the preceding example, 3. A tag is important for future work that might be necessary for patch creation or bug-fix releases. Another importance of a release tag is to facilitate investigation regarding issues in the associated release. If a patch or subsequent change of a tag is considered necessary, then you must create a branch. A branch is a copy of a location elsewhere in the repository and does not differ in composition from a tag.

A repository is not automatically updated unless the administrator runs 'svnadmin upgrade'. To be sure of the version number of the repository, check the 'format' file.

This works only if the server will display this information, some server like google code hosting does not. Is that the server version, or the repository version? CollabNet also does not display a version number - either visibly or in the source of the page. Show 3 more comments.

This answer is not clear that svnserve --version must be used on the server. If it's run on the client, it gives the version number of the client, not the server. This is a good collection. This answer is being discussed on Meta. SmartSVN view page source does NOT show version numbers, and the mention to click the powered by link leaves the server, and takes one to the vendor site instead visualsvn.
For completeness. Milen A. Radev Milen A. Radev As Joe J mentions below, I believe this will just give you the version of the svnserve client program which will most likely match the svn client program — Kirby.

Likewise this is the only answer that worked for me amongst all the answers here. I used Firefox Live HTTP Headers and to read the response of the server because I was also having ssl certificate problems that I didn't feel like going to the trouble to figure out. Thank you, Christopher — Kirby. Kirby I've added a --no-check--certificate parameter, a --user and --password to handle servers that require credentials but don't have a valid ssh certificate.

The cvs2svn conversion tool seems to be what most people use. If you are running a Linux or BSD-based system, your distribution might have a cvs2svn package. The Subversion client can go through a proxy, if you configure it to do so.
First, edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. There are comments in the file explaining what to do. If you don't have that file, get the latest Subversion client and run any command; this will cause the configuration directory and template files to be created.
In general, solving this depends on the particular proxy software. For Squid, the config option is. If it's difficult or impossible to get the proxy to allow Subversion traffic, but you want to check out the Subversion sources, you may be able to go around the proxy. Some proxies that filter port 80 nevertheless allow anything on port In many other cases proxies don't filter https as strict as they filter http.
The svn. Of course, your svn client will have to have been built with ssl support. You can check to see whether the 'https' scheme is supported by running svn --version. A simple option is to use the svnserve server instead of Apache. See chapter 6 in the Subversion book for details. However, if your admins don't want you to run Apache, it's very likely they don't want you to run a custom server process on port either! So the rest of this answer assumes that your admins are okay with you using an existing SSH infrastructure.
This makes your SSH program launch a private 'svnserve' process on the remote box, which accesses the repository as your UID and tunnels the information back over the encrypted link. You would connect via SSH to a machine behind your firewall that can access your Subversion server. Note that this SSH server does not have to be the same as where Subversion is installed. It can be, but it doesn't have to be. Then, you create a local port forward that connects to the HTTP server that houses your Subversion repository.
You would then 'connect' to the Subversion repository via this local port. Then, the request will be sent 'tunneled' via SSH server to your Subversion server. Your company allows SSH access via publicly accessible ssh-server. Example : client connecting to ssh-server with port-forwarding and checking out via the port forward.
Note that your svn-server. This will allow your Subversion server not to require root access. It depends upon the projects involved. If the projects are related, and are likely to share data, then it's best to create one repository with several subdirectories like this:. If the projects are completely unrelated, and not likely to share data between them, then it's probably best to create separate and unrelated repositories.
If you don't care about retaining all the history of one of the repositories, you can just create a new directory under one project's repository, then import the other. If you care about retaining the history of both, then you can use 'svnadmin dump' to dump one repository, and 'svnadmin load' to load it into the other repository.
The revision numbers will be off, but you'll still have the history. As long as the merging takes place in separate directory trees, you can use svn's version of CVS modules.
Set the svn:externals property on a directory to checkout directories from other repositories whenever the original directory is checked out. The repository remains separate, but in the working copy it appears that they have been merged. If you commit to the imported directory, it will affect the external repository. The merge isn't completely clean: the import only affects working copies, so you won't be able to use a URL in the first repository to access modules imported from the second.
They remain separate URLs. There are also some helpful tools floating around on the internet, to select and reorder revisions when merging several repositories. For instance the svn-merge-repos. If you are using a repository with the Berkeley DB back end default for repositories created with Subversion 1. While Berkeley DB databases and log files can be stored on remote filesystems, the Berkeley DB shared region files cannot be stored on a remote filesystem, so the repository may be safely accessed by only a single filesystem client, and not all Subversion functionality will be available to even that one client.
On Linux NFS servers, due to the volume of renames used internally in Subversion when checking out files, some users have reported that 'subtree checking' should be disabled it's enabled by default. We've had at least one report of working copies getting wedged after being accessed via SMB. The server in question was running a rather old version of Samba 2. The problem didn't recur with a newer Samba 3.
Try to have as few users access the repository as possible. For example, run apache or 'svnserve -d' as a specific user, and make the repository wholly owned by that user. In that case, read the last section in chapter 6 , and pay particular attention to the "checklist" sidebar at the bottom.
It outlines a number of steps to make this scenario safer. In addition to regular Unix permissions, under SELinux every file, directory, process, etc. When a process attempts to access a file, besides checking the Unix permissions the system also checks to see if the security context of the process is compatible with the security context of the file.
Fedora Core 3, among other systems, comes with SELinux installed by default, configured so that Apache runs in a fairly restricted security context. To run Subversion under Apache, you have to set the security context of the repository to allow Apache access or turn off the restrictions on Apache, if you think all this is overkill. The chcon command is used to set the security context of files similarly to how the chmod sets the traditional Unix permissions. For example, one user had to issue this command.
There are special cases where you might want to destroy all evidence of a file or commit. Perhaps somebody accidentally committed a confidential document. This isn't so easy, because Subversion is deliberately designed to never lose information. Revisions are immutable trees which build upon one another. Removing a revision from history would cause a domino effect, creating chaos in all subsequent revisions and possibly invalidating all working copies.
The project has plans, however, to someday implement an svnadmin obliterate command which would accomplish the task of permanently deleting information. See issue In the meantime, your only recourse is to svnadmin dump your repository, then pipe the dumpfile through svndumpfilter excluding the bad path into an svnadmin load command. See chapter 5 of the Subversion book for details about this.
An alternative approach is to replicate the repository with svnsync after configuring path-based authorization rules that deny read access to any paths that need to be filtered from history. Unlike svndumpfilter , svnsync will automatically translate copy operations with an unreadable source path into normal additions, which is useful if history involving copy operations needs to be filtered. 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:. 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.
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. Once you've digested that, send a mail to the dev list with the word [PATCH] and a one-line description in the subject, and include the patch inline in your mail unless your MUA munges it up totally.
Then a committer will pick it up, apply it making any formatting or content changes necessary , and check it in. Of course, the email you send should contain a nice long explanation about what the patch does, as per the Subversion Community Guide , but you already know that, since you read and completely understood it before actually hacking the code, right?
This takes advantage of a not-immediately-obvious feature of svn checkout : you can check out a directory from the repository directly into an existing directory. Once that is done, you can use normal svn add commands to select files and subtrees to add to the repository. If the entire contents of the directory shall be imported, rather than a subset of contents, this shorter sequence of commands can be used to perform the import and then transform the directory into a Subversion working copy:.
There is an issue filed for enhancing svn import to be able to convert the imported tree to a working copy automatically; see issue Subversion's repository database schema has changed occasionally during development.
To take advantage of new features, you may have to dump and load the repository to recreate the back-end database. However, most upgrades of Subversion do not involve a dump and load.
These need to be copied over manually from source to target see below in the "complex procedure". If you need to copy the complete repository, without rebuilding the back-end database, svnadmin hotcopy may be a better option. For larger repositories, where you want to minimize the maintenance window, a slightly more complex procedure can be used. You can iterate over this as long as you keep the old repository open At the end you make the original repository inaccessible for a couple of minutes, while you enable the new one Caveat: if you move your new repos in the same disk location as the old one, and you use Apache httpd to serve it, make sure you restart httpd to reset its caches.
Tip: for a large repo I strongly suggest building the new repository the target of your 'svnadmin load' on very fast storage, even ramdisk if possible, and running 'svnadmin pack' while on fast storage and copy it over to the final disk afterwards. It's the 'svnadmin load' part that is very time-consuming right now this will probably be much improved in svn 1.
See this section of the Subversion book for more details on dumping and loading. You can ignore this minor corruption while loading into your new repository by adding --bypass-prop-validation to your 'svnadmin load' command you can always repair this later in the new repository. There is no standard procedure for normalizing the line endings in the svn:log property, but using the administrative commands 'svnlook propget', 'svnlook log' and 'svnadmin setlog' can get you there:.
You can stitch them together into a script to handle all revisions in a repository, like in these bash oneliners:. This FAQ entry has not been updated since and is known to contain information no longer accurate or relevant.
Because the client never asks for credentials, any action that requires authentication will fail. We recommend that you live with ". Or you could use a completely custom name for the administrative directory. We recommend against this, because your working copy would probably not work with Subversion clients other than the one you customized. This problem comes up in two situations. If you're adding files on an operating system with a case-insensitive filesystem, such as Windows, you might find you accidentally add a file with the wrong case in the filename.
Alternatively, you may just decide to change the case of an existing file in the repository. If you're working in a case-sensitive file system, this is no problem at all. Just move the file to the new name, e. From Subversion 1.
If you are using Subversion 1. In this case, you can accomplish this by copying the file somewhere temporary, deleting the file from Subversion, then adding the copy with the correct case.
Or a better way is to perform a move operation with Subversion URLs. Using URLs is recommended, because it will preserve history for the file, and will take effect immediately. Both ways will leave Windows working copies with problems, however, because Windows can still get confused when trying to update the conflicting filenames. You'll get a message like svn: Failed to add file 'File. One way of fixing the problem is to delete your working copy and check out again. If you do not want to do this, you must perform a two step update.
The first update will remove file. Or if you had a lot of problematic files, you can update the working copy this way:. As you can see, adding a file with the wrong case is tricky to fix on an operating system that has a case insensitive filesystem.
Do try to get it right when you add the file the first time! To prevent the problem from occurring in the first place, you can create a pre-commit hook that calls the file check-case-insensitive. As shown below it is possible to merge from a branch to the trunk without remembering one revision number. Or vice versa not shown in the example. Subversion increments the revision number of the repository as a whole, so it can't expand any keyword to be that number - it would have to search and possibly modify every file in your working copy on every update and commit.
The information you want the revision of your working copy is available from the command svnversion ; it gives you information on the revision level of a working copy given a path see svnversion --help for details. You can incorporate it into your build or release process to get the information you need into the source itself. For example, in a build environment based on GNU make , add something like this to your Makefile :. Note that this will not work on non-GNU versions of make.
Don't use it if your build process needs to be portable. Windows users may want to use SubWCRev. Another alternative is creating a wrapper for 'svn commit', which does some automatic replacement in files before commit be careful not to mess things up though -- silent manipulation of files right before commit can be scary for a user.
That way you can inject any metadata you want and it will be committed with the regular content of the file into the repository. If you want to retrieve a log for a specific file, you can run 'svn log your-file-name' or 'svn log url-to-your-file'. There are no plans to implement it ourselves or accept patches which implement this feature.
If you want to distribute your files with some kind of changelog included, you might be able to work around this limitation in your build system.
The answer is: don't put that file under version control. Instead, put a template of the file under version control, something like "file. Then, after the initial 'svn checkout', have your users or your build system do a normal OS copy of the template to the proper filename, and have users customize the copy.
The file is unversioned, so it will never be committed. And if you wish, you can add the file to its parent directory's svn:ignore property, so it doesn't show up as '? Its auth caching is external to Subversion, and must be set up independently of Subversion. OpenSSH includes ssh-keygen to create the keys, ssh-agent to cache passphrases, and ssh-add to add passphrases to the agent's cache.
A popular script to simplify usage of ssh-agent is keychain. Setting up ssh-agent is outside the scope of this document, but a Google search for "ssh-agent" will quickly get you answers.
Or if you're really impatient, try this one:. Note: this all assumes you're using OpenSSH. There are other ssh implementations out there, and presumably they will allow you to do something similar, but we don't yet know the details. You've tried fiddling with their various login files, like. That's because ssh ignores those files when the Subversion client invokes it. But there's no need to modify PATH ; instead, you can directly give ssh the full name of the svnserve command.
Here's how to do it:. You also might want to specify the full path to the Subversion repository in the command by using the -r option , to save your users some typing. This file discusses this topic in more detail. Subversion will not change a file's contents by default; you have to deliberately set the svn:eol-style or svn:keywords property on a file for that to happen. That makes Subversion a lot safer than CVS's default behavior, but with that safety comes some inconvenience.
Answering the first question: to set properties on all files already in the repository, you'll need to do it the hard way. All you can do is run svn propset on every file in a working copy , and then svn commit.
Scripting can probably help you with this. But what about future files? Unfortunately, there's no server mechanism to automatically set properties on files being committed.
This means that all of your users need to remember to set certain properties whenever they svn add a file. Fortunately, there's a client-side tool to help with this. Read about the auto-props feature in the book. You need to make sure all your users configure their clients' auto-props settings appropriately. However, this approach may be overkill.
If somebody forgets to set svn:eol-style , for example, it will be noticed the minute somebody else opens the file on a different OS.
Once noticed, it's easy to fix: just set the property and commit. Note: many users have asked for a feature whereby the server automatically "broadcasts" run-time settings to clients, such as auto-props settings. There's already a feature request filed for this issue , though this feature is still being debated by developers, and isn't being worked on yet. Note that there is no need to escape the quotes in the Windows shell as they are not part of the syntax for the set command.
On UNIX systems you would need to follow your shell's specific methods for setting the variable. For example, in a bash shell, the following should work:.
For example, if the options -nx -r would be wanted for the above editors, the following will provide those options:. This is done all the time, and is easily accomplished by adding a post-commit hook script to your repository. Read about hook scripts in Chapter 5 of the book. The basic idea is to make the "live site" just an ordinary working copy, and then have your post-commit hook script run 'svn update' on it.
In practice, there are a couple of things to watch out for. The server program performing the commit svnserve or apache is the same program that will be running the post-commit hook script. That means that this program must have proper permissions to update the working copy. In other words, the working copy must be owned by the same user that svnserve or apache runs as -- or at least the working copy must have appropriate permissions set. Compile a tiny C program:. Then in the post-commit hook, add a line to run the binary.
If you have problems getting the hook to work, see "Why aren't my repository hooks working? Also, you'll probably want to prevent apache from exporting the. Add this to your httpd. Finally, if the working copy to be updated isn't on the same machine as the Subversion server, svnpubsub can be used on the Subversion server to advertise the commit to a listening svnwcsub client on the Web server.
Subversion does not support checkout of a single file, it only supports checkout of directory structures. However, you can use 'svn export' to export a single file. This will retrieve the file's contents, it just won't create a versioned working copy. The basic design of the working copy has two rules: 1 edit files as you please, and 2 use a Subversion client to make any tree-changes add, delete, move, copy. If these rules are followed, the client can sucessfully manage the working copy.
If renames or other rearrangements happen outside of Subversion, then the UI has been violated and the working copy might be broken. The client cannot guess what happened. People sometimes run into this problem because they want to make version control "transparent". They trick users into using a working copy, then have a script run later that tries to guess what happened and run appropriate client commands.
Unfortunately, this technique only goes a short distance. But if a move or copy has happened, you're out of luck. Even if the script has a foolproof way of detecting these things, 'svn mv' and 'svn cp' can't operate after the action has already occurred.
In summary: a working copy is wholly under Subversion's control, and Subversion wasn't designed to be transparent. If you're looking for transparency, try setting up an apache server and using the "SVNAutoversioning" feature described in appendix C of the book.
This will allow users to mount the repository as a network disk, and any changes made to the volume cause automatic commits on the server. For versions 1. When you first add or import a file into Subversion, the file is examined to determine if it is a binary file. You can always override this by using the auto-props feature or by setting the property manually with svn propset.
This feature is used only for binary files for which no MIME type is found via auto-props or the mime-types-file configuration option. If libmagic identifies a file as a text file, Subversion will treat the file as a text file by default.
In all other respects, Subversion treats binary files the same as text files, e. Note that whether or not a file is binary does not affect the amount of repository space used to store changes to that file, nor does it affect the amount of traffic between client and server. For storage and transmission purposes, Subversion uses a diffing method that works equally well on binary and text files; this is completely unrelated to the diffing method used by the 'svn diff' command.
Technically speaking, Subversion does not expand wildcards in local paths either, but on most operating systems the shell expands wildcards in local paths in the command line before passing the resulting list to Subversion. In Subversion v1. You have to issue multiple commands. If you happen to have a working copy that contains all the source files as well as the destination directory, then you can exploit your shell's wildcard feature to do the move, like this for Bash :.
In any case, you can always accumulate a list of the names of the source files, and then run "svn mv" on each item in that list, like this:. Note, however, that this will generate one commit per source file; that's in contrast to the above method using a working copy which generates just one commit total.
There is a program called "svnmucc" previously "mucc" , whose source is distributed with Subversion, that enables you to combine multiple commands into one commit. See the Tools and Contrib page. People frequently want to use Subversion to track their local changes to third-party code, even across upgrades from the third-party — that is, they want to maintain their own divergent branch, while still incorporating new releases from the upstream source.
This is commonly called a vendor branch the term long predates Subversion , and the techniques for maintaining one in Subversion are described here. If the vendor code is hosted in a remote Subversion repository, then you can use Piston to manage your copy of the vendor's code. This solution does not make use of the space saving features in the Subversion backend when you copy new code over old code; in this solution, each import of a vendor code gets an entire new copy and there is no space savings for identical files.
Use 'svn merge' or 'svn copy', as described in the Subversion book. Your working copy is not corrupt, nor is your data lost. Subversion's working copy is a journaling system, meaning that it logs everything it is about to do before it does so. If the svn client program is interrupted violently segfault or killed, not with Control-C , then one or more lockfiles are left behind, along with logfiles describing unfinished business.
Any other process that attempts to access the working copy will fail when it sees the locks. To awaken your working copy, you need to tell the svn client to finish the work. Simply run:. You may have had a commit that went sour between the time the new revision was added in the server and the time your client performed its post-commit admin tasks including refreshing your local text-base copy.
This might happen for various reasons including rarely problems in the database back end or more commonly network dropouts at exactly the wrong time. If this happens, it's possible that you have already committed the very changes you are trying now to commit. You can use 'svn log -rHEAD' to see if your supposed-failed commit actually succeeded.
If it did, run 'svn revert' to revert your local changes, then run 'svn update' to get your own changes back from the server. Note that only 'svn update' brings your local copies up-to-date; revert doesn't do that. When Subversion commits, the client only bumps the revision numbers of the nodes the commit touches, not all nodes in the working copy. This means that in a single working copy, the files and subdirectories might be at different revisions, depending on when you last committed them.
In certain operations for example, directory property modifications , if the repository has a more recent version of the node, the commit will be rejected, to prevent data loss.
See Mixed revisions have limitations in the Version Control with Subversion book for details. You might be genuinely out of date — that is, you're trying to commit a change to a file that has been changed by someone else since you last updated your copy of that file. Again, 'svn update' is the way to fix this. In order to include your new file in the patch you likely ran the svn add command so that the svn diff command would include the new file in the patch.
If your patch is committed to the code base and you run an svn update , then you might receive an error message of: "svn: Failed to add file 'my. The reason that you received this error is that you still have your local copy of the file in your working copy. The steps to correct this problem are:. Subversion uses a plugin system to allow access to repositories. When you attempt to perform an operation in Subversion, the program tries to dynamically load a plugin based on the URL scheme.
It also happens when you build Subversion with shared libraries, then attempt to run it without first running 'make install'. Probably you just need to get the latest platform SDK. Visual Studio can use a web subsystem for ASP. Net, which uses frontpage server extensions to do remote publishing through IIS. This subsystem rejects any pathname that starts with ". This causes a problem when you try to remotely publish a Subversion working copy, because of the ".
The error message says something like "unable to read project information". See the relevant section of the Subversion 1. Subversion places a very high priority on protecting your data, and not just your versioned data. Modifications that you make to already-versioned files, and new files scheduled for addition to the version control system, must be treated with care. Making the svn revert command require an explicit target—even if that target is just '. This requirement as well as requiring you to supply the --recursive -R flag if you want that behavior is intended to make you really think about what you're doing, because once your files are reverted, your local modifications are gone forever.
If you allow anonymous write access to the repository via Apache, the Apache server never challenges the SVN client for a username, and instead permits the write operation without authentication. Since Subversion has no idea who did the operation, this results in a log like this:. See the Subversion book to learn about configuring access restrictions in Apache. This is not really a bug in Subversion, which makes it difficult for us to fix.
A summary of the current state of the investigation is available here. A workaround that should reduce the incidence rate for most people was implemented in revision ; if you have an earlier version, please update to the latest release. This is usually due to a lack of available entropy on the system.
You probably need to configure the system to gather entropy from sources such as hard-disk and network interrupts. Consult your system manpages, specifically random 4 and rndcontrol 8 on how to effect this change. It means your httpd.
