New Revision: 956921
URL: http://svn.apache.org/viewvc?rev=956921&view=rev
Log:
Correct the FSFS structure documentation for lock storage, which
doesn't appear to match the implementation.
If a repository has a locked file /A/D/G/rho, there will be a
serialized hash file for that path (as an MD5 digest,
".../db/2d9/2d9ce8aaac06331d75dae9dad43473bd", in this example), and
that digest file will be directly referenced from the digest files for
/A/D/G, /A/D, /A and /. The documentation implies that the digest
file for /A/D/G/rho will only be referenced by a digest file for
/A/D/G (which is then referenced by the digest file for /A/D, which
itself is referenced by the digest for /A, etc.)
