svn repository on Windows network share

阅读更多关于 svn repository on Windows network share

问题 Is it safe for multiple computers to concurrently access an svn repository stored on a shared filesystem? I'm building an application in which each Windows client machine has a local working set of files, and can periodically synchronize with the rest of the team. From a server standpoint, I'd like to rely on nothing except a Windows shared mount point. Does the svn file:// URL protocol support shared filesystems, or does it assume that the filesystem is local? The Subversion docs mention

How can I determine whether a Subversion repository was created with a BDB or fsfs backend?

问题 If you arrive at a pre-existing Subversion repository, how can you determine whether it was created with a BDB or fsfs backend storage method? 回答1: Open the file repository\db\fs-type with a text editor. It either contains bdb or fsfs indicating which backend it uses. 来源： https://stackoverflow.com/questions/6122054/how-can-i-determine-whether-a-subversion-repository-was-created-with-a-bdb-or-fs

What is the maximum revision number supported by SVN?

阅读更多关于 What is the maximum revision number supported by SVN?

问题 What is the maximum revision number supported by SVN? The repo is of type FSFS, hosted on a Fedora box. Thank you, 回答1: If you're using a 32-bit computer it's 2147483647, that's 2 31 -1, the maximum value of a signed 32-bit integer. For a 64-bit computer, it's... more. In any case, it should be enough for any practical purpose where humans are doing commits. In practice, you're probably going to run out of disk space or your directory indexes become too slow before you hit the maximum

Migrating Subversion Repositories across servers

阅读更多关于 Migrating Subversion Repositories across servers

问题 We're in the process of moving servers and one of the last items is moving over the svn repositories. There are about 10 gigs of various svn repositories. They were created using this command: svnadmin create --fs-type fsfs Server A(original) has svn 1.4 while Server B(target) has svn 1.6. My thought was to use rsync to migrate the whole set of repositories (they are all in 1 folder on the server), but I am worried that some things might either not get migrated or I need special switches for

问题 How can I determine current version of my repository to see if I need to upgrade it (svnadmin upgrade)?

How exactly does subversion store files in the repository?

阅读更多关于 How exactly does subversion store files in the repository?

问题 I read the subversion book and it is clear to me that subversion does not store individual files but only deltas in order to minimize disk space. Subversion also does the same with binary files as well (this used to be a huge weakness of CVS). However I do not understand the exact mechanism. When I commit a file what happens? Subversion stores only the diff (and already has the old version) Subversion deletes the previous version, stores the new file intact and creates a reverse diff in order

Where does SVN store the data on the server side?

阅读更多关于 Where does SVN store the data on the server side?

问题 I have created an svn repo on my web host server and successfully commit files to it and updated files from it but I can't seem to actually find the files on the server! My svn repo is in ~/svn/my-first-repo/ which contains the following: ./ ../ README.txt conf/ db/ format hooks/ locks/ . But where are the files I'm actually versioning?! It's definitely worked because I was able to checkout the same remote repo into another local directory and all the files magically appeared! As if from

350GB SVN repo creates atleast 1MB revision for even a simplest task like branch/tag

阅读更多关于 350GB SVN repo creates atleast 1MB revision for even a simplest task like branch/tag

This all started when I noticed that my repository size is increasing at a daily rate of 1GB. I did a simple test. Created a branch/tag of an existing folder that had a size of 35KB. I took note of revision number and went to $REPO/db/revs/<K-rev>/rev-number/ and checked the size of the revision. It was 1 mega byte. That sounds fishy. Any ideas on what might be wrong here. My repo is about 350GB in size with about 600,000 revisions. P.S. I have already started a rebuild of the whole repository to see if that makes any difference but it will probably take days to complete. Posted same question
