Name svnadmin hotcopy — Make a hot copy of a repository. Synopsis svnadmin hotcopy REPOS_PATH NEW_REPOS_PATH Description This subcommand makes a full “hot” backup of your repository, including all hooks, configura- tion files, and, of course, database files. If you pass the clean-logs option, svnadmin will perform a hotcopy of your repository, and then remove unused Berkeley DB logs from the ori- ginal repository. You can run this command at any time and make a safe copy of the reposit- ory, regardless of whether other processes are using the repository. Options clean-logs As described in the section called “Berkeley DB”, hot-copied Berkeley DB reposit- ories are not portable across operating systems, nor will they work on machines with a different “endianness” than the machine where they were created. Subversion Complete Reference 275 Name svnadmin list-dblogs — Ask Berkeley DB which log files exist for a given Subversion repository (applies only to repositories using the bdb backend). Synopsis svnadmin list-dblogs REPOS_PATH Description Berkeley DB creates logs of all changes to the repository, which allow it to recover in the face of catastrophe. Unless you enable DB_LOG_AUTOREMOVE, the log files accumulate, although most are no longer used and can be deleted to reclaim disk space. See the section called “Managing Disk Space” for more information. Subversion Complete Reference 276 Name svnadmin list-unused-dblogs — Ask Berkeley DB which log files can be safely deleted (applies only to repositories using the bdb backend). Synopsis svnadmin list-unused-dblogs REPOS_PATH Description Berkeley DB creates logs of all changes to the repository, which allow it to recover in the face of catastrophe. Unless you enable DB_LOG_AUTOREMOVE, the log files accumulate, although most are no longer used and can be deleted to reclaim disk space. See the section called “Managing Disk Space” for more information. Examples Remove all unused log files from a repository: $ svnadmin list-unused-dblogs /path/to/repos /path/to/repos/log.0000000031 /path/to/repos/log.0000000032 /path/to/repos/log.0000000033 $ svnadmin list-unused-dblogs /path/to/repos | xargs rm ## disk space reclaimed! Subversion Complete Reference 277 Name svnadmin load — Read a “dumpfile”-formatted stream from stdin. Synopsis svnadmin load REPOS_PATH Description Read a “dumpfile”-formatted stream from stdin, committing new revisions into the repository's filesystem. Send progress feedback to stdout. Options quiet (-q) ignore-uuid force-uuid use-pre-commit-hook use-post-commit-hook parent-dir Example This shows the beginning of loading a repository from a backup file (made, of course, with svnadmin dump): $ svnadmin load /usr/local/svn/restored < repos-backup <<< Started new txn, based on original revision 1 * adding path : test done. * adding path : test/a done. … Or if you want to load into a subdirectory: $ svnadmin load parent-dir new/subdir/for/project /usr/local/svn/restored < repos-backup <<< Started new txn, based on original revision 1 * adding path : test done. * adding path : test/a done. … Subversion Complete Reference 278 Name svnadmin lslocks — Print descriptions of all locks. Synopsis svnadmin lslocks REPOS_PATH Description Print descriptions of all locks in a repository. Options None Example This lists the one locked file in the repository at /svn/repos: $ svnadmin lslocks /svn/repos Path: /tree.jpg UUID Token: opaquelocktoken:ab00ddf0-6afb-0310-9cd0-dda813329753 Owner: harry Created: 2005-07-08 17:27:36 -0500 (Fri, 08 Jul 2005) Expires: Comment (1 line): Rework the uppermost branches on the bald cypress in the foreground. Subversion Complete Reference 279 Name svnadmin lstxns — Print the names of all uncommitted transactions. Synopsis svnadmin lstxns REPOS_PATH Description Print the names of all uncommitted transactions. See the section called “Removing dead trans- actions” for information on how uncommitted transactions are created and what you should do with them. Examples List all outstanding transactions in a repository. $ svnadmin lstxns /usr/local/svn/repos/ 1w 1x Subversion Complete Reference 280 Name svnadmin recover — Bring a repository database back into a consistent state (applies only to repositories using the bdb backend). In addition, if repos/conf/passwd does not exist, it will create a default password file . Synopsis svnadmin recover REPOS_PATH Description Run this command if you get an error indicating that your repository needs to be recovered. Options wait Examples Recover a hung repository: $ svnadmin recover /usr/local/svn/repos/ Repository lock acquired. Please wait; recovering the repository may take some time Recovery completed. The latest repos revision is 34. Recovering the database requires an exclusive lock on the repository. (This is a “database lock”; see The three meanings of “lock”.) If another process is accessing the repository, then svnadmin recover will error: $ svnadmin recover /usr/local/svn/repos svn: Failed to get exclusive repository access; perhaps another process such as httpd, svnserve or svn has it open? $ The wait option, however, will cause svnadmin recover to wait indefinitely for other pro- cesses to disconnect: $ svnadmin recover /usr/local/svn/repos wait Waiting on repository lock; perhaps another process has it open? ### time goes by… Repository lock acquired. Please wait; recovering the repository may take some time Recovery completed. The latest repos revision is 34.

Synopsis svnadmin rmlocks REPOS_PATH LOCKED_PATH Description Remove lock from each LOCKED_PATH.

Synopsis svnadmin rmtxns REPOS_PATH TXN_NAME Description Delete outstanding transactions from a repository. This is covered in detail in the section called “Removing dead transactions”. Options quiet (-q) Examples Remove named transactions: $ svnadmin rmtxns /usr/local/svn/repos/ 1w 1x Fortunately, the output of lstxns works great as the input for rmtxns: $ svnadmin rmtxns /usr/local/svn/repos/ `svnadmin lstxns /usr/local/svn/repos/` Which will remove all uncommitted transactions from your repository.
