How can I determine current version of my repository to see if I need to upgrade it (svnadmin upgrade)?
In reality I'm hosting SVN with 3rd party and I want to find out if I need to ask them to upgrade my repos or not.
I'm asking since 1.5 server will keep repo version at 1.4, unless I miss something?
Have a look at <REPO>/db/format. After upgrading to 1.5 format, my format file shows:
3
layout sharded 1000
Before it used to be:
2
Take the http or https link to your repository and cut & paste it into a browser. The Subversion repository server version appears in the footer by default.
Powered by Subversion version 1.4.5 (r25188).
One would assume that a 1.4 server won't be running against a 1.5 repository.
For details, see the Subversion 1.5 Release Notes
Thanks to @Omus for the correction.
You can check the content of the file "format" under the "db" directory. If it shows 3 then it has been upgraded to 1.5 (that's the version of the updated fielsystem). If it is 2 then it is 1.4 or older.
I would also suggest spoofing response headers because some server installations (VisualSVN Server comes to mind) uses custom pages which unfortunately doesn't show Subversion server version.
You could use Fiddler2 to spoof request/response to the server. If You're using an HTTPS connection be sure to check "Decrypt HTTPS traffic" option in: Tools->Fiddler Options->HTTPS
If you use VisualSVN Server you can find out the format of the repository via the VisualSVN Server Manager console or via PowerShell. Read the article KB135: Understanding the Subversion repository types and formats for more information.
