Re: svnadmin verify

Thanks. I wrote a script to output the exit code of the supplied command, and got the following from a new repository:

$ show_exit_code "svnadmin verify ."
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
* Verified revision 3.
Exit Code: 0

...and the following after I added a couple of garbage characters to db/revs/3

$ show_exit_code "svnadmin verify ."
* Verified revision 0.
* Verified revision 1.
* Verified revision 2.
svnadmin: Missing node-id in node-rev
Exit Code: 1

With different corruptions I got different error messages, but they all began with "svnadmin:", so I guess that's what I need to grep for. The return code was always 1 though. I guess that answers both my questions! Thanks for your help.

One further question - is there any way you can think of for the script to get the revision number of the bad revision? It's not a massive issue, as it will need manual intervention anyway and you can check then, but it might be a useful thing to send in the error output, if possible.

  you are correct about svnadmin verify. It only tells you if there is corruption. A successfull verification seems to return 0 and an invalid verification a non-zero (usually 1) - as with most unix commands. You can test this easily. Make a copy of your repository with a new name like test. Corrupt a file and run svnadmin verify and test $?.

  Hope this helps
