I've posted messages about the following problem in the users list, but here's other information.
After a "svnadmin upgrade" with svn version 1.5.1 (r32289), which terminated without any error, and svn-populate-node-origins-index, the repository got corrupted: /svnroot/mpfr/db/format now contains: 3 layout linear without an ending \n, while the documentation[*] says: The format file is a single line of the form "<format number>\n", followed by any number of lines specifying 'format options' - additional information about the filesystem's format. Each format option line is of the form "<option>\n" or "<option> <parameters>\n". The "current" file hasn't been updated to the new format; it is still in the format 2 (with the old timestamp). According to the documentation: The format of the "current" file is: * Format 3 and above: a single line of the form "<youngest-revision>\n" giving the youngest revision for the repository. * Format 2 and below: a single line of the form "<youngest-revision> <next-node-id> <next-copy-id>\n" giving the youngest revision, the next unique node-ID, and the next unique copy-ID for the repository. [*] http://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_fs_fs/structure The following files/directory have been created: -rw-r--r-- 1 www-data scm_mpfr 2 2010-08-06 16:01:43 txn-current -rw-r--r-- 1 www-data scm_mpfr 0 2010-08-06 16:01:43 txn-current-lock drwxr-sr-x 2 www-data scm_mpfr 4096 2010-08-06 16:01:43 txn-protorevs and they prevent any commit (due to the lock, I assume). The contents themselves are correct (tested with "svnadmin verify" and a dump comparison).
